2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	960 - Phase 2 of the Great Renaming has been executed. The header files
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	961 now use the new names (PyObject instead of object, etc.). The linker
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	962 also sees the new names. Most source files still use the old names,
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	963 by virtue of the rename2.h header file. If you include Python.h, you

2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	969 execution") are in place. Specifically, the import statement is
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	970 implemented by calling the built-in function __import__, and the
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	971 built-in names used in a particular scope are taken from the
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	972 dictionary __builtins__ in that scope's global dictionary. See also

2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	976 "from a.b.c import name". No officially supported implementation
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	977 exists, but one can be prototyped by replacing the built-in __import__
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	978 function. A proposal by Ken Manheimer is provided as newimp.py.

2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	980 - All machinery used by the import statement (or the built-in
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	981 __import__ function) is now exposed through the new built-in module
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	982 "imp" (see the library reference manual). All dynamic loading
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	983 machinery is moved to the new file importdl.c.

2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	985 - Persistent storage is supported through the use of the modules
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	986 "pickle" and "shelve" (implemented in Python). There's also a "copy"
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	987 module implementing deepcopy and normal (shallow) copy operations.

2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	990 - Documentation strings for many objects types are accessible through
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	991 the __doc__ attribute. Modules, classes and functions support special
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	992 syntax to initialize the __doc__ attribute: if the first statement
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	993 consists of just a string literal, that string literal becomes the
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	994 value of the __doc__ attribute. The default __doc__ attribute is
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	995 None. Documentation strings are also supported for built-in
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	996 functions, types and modules; however this feature hasn't been widely
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	997 used yet. See the 'new' module for an example. (Basically, the type
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	998 object's tp_doc field contains the doc string for the type, and the
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	999 4th member of the methodlist structure contains the doc string for the
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	1000 method.)
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	1001
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	1002 - The __coerce__ and __cmp__ methods for user-defined classes once
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	1003 again work as expected. As an example, there's a new standard class

2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	1007 third argument to specify the buffer size, and default their second
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	1008 (mode) argument to 'r' -- in analogy to the builtin open() function.
2a4d130373db added 1.2 news Guido van Rossum <guido@python.org> parents: 2067 diff changeset	1009 The same applies to posixfile.open() and the socket method makefile().

1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1086 This release adds several new features, improved configuration and
1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1087 portability, and fixes more bugs than I can list here (including some
1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1088 memory leaks).
1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1089
1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1090 The source compiles and runs out of the box on more platforms than
1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1091 ever -- including Windows NT. Makefiles or projects for a variety of

1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1094 APOLOGY: some new features are badly documented or not at all. I had
1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1095 the choice -- postpone the new release indefinitely, or release it
1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1096 now, with working code but some undocumented areas. The problem with
1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1097 postponing the release is that people continue to suffer from existing
1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1098 bugs, and send me patches based on the previous release -- which I
1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1099 can't apply directly because my own source has changed. Also, some
1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1100 new modules (like signal) have been ready for release for quite some
1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1101 time, and people are anxiously waiting for them. In the case of
1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1102 signal, the interface is simple enough to figure out without
1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1103 documentation (if you're anxious enough :-). In this case it was not
1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1104 simple to release the module on its own, since it relies on many small

1b99451fa143 Moved 1.1 and 1.1.1 news here Guido van Rossum <guido@python.org> parents: 1948 diff changeset	1108 explain how to use them. Documentation for the Tk interface, written

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1462 * The built-in module strop now defines fast versions of three more
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1463 functions of the standard string module: atoi(), atol() and atof().
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1464 The strop versions of atoi() and atol() support an optional second
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1465 argument to specify the base (default 10). NOTE: you don't have to
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1466 explicitly import strop to use the faster versions -- the string
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1467 module contains code to let versions from stop override the default
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1468 versions.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1469
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1470 * There is now a working Lib/dospath.py for those who use Python under
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1471 DOS (or Windows). Thanks, Jaap!

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1473 * There is now a working Modules/dosmodule.c for DOS (or Windows)
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1474 system calls.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1475
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1476 * Lib.os.py has been reorganized (making it ready for more operating
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1477 systems).
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1478
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1479 * Lib/ospath.py is now obsolete (use os.path instead).
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1480
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1481 * Many fixes to the tutorial to make it match Python 1.0. Thanks,
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1482 Tim!
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1483
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1484 * Fixed Doc/Makefile, Doc/README and various scripts there.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1485
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1486 * Added missing description of fdopen to Doc/libposix.tex.

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1488 * Made cleanup() global, for the benefit of embedded applications.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1489
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1490 * Added parsing of addresses and dates to Lib/rfc822.py.

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1492 * Small fixes to Lib/aifc.py, Lib/sunau.py, Lib/tzparse.py to make
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1493 them usable at all.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1494
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1495 * New module Lib/wave.py reads RIFF (*.wav) audio files.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1496
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1497 * Module Lib/filewin.py moved to Lib/stdwin/filewin.py where it
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1498 belongs.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1499
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1500 * New options and comments for Modules/makesetup (used by new
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1501 Extension mechanism).
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1502
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1503 * Misc/HYPE contains text of announcement of 1.0.0 in comp.lang.misc
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1504 and elsewhere.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1505
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1506 * Fixed coredump in filter(None, 'abcdefg').
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1507
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1508

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1510 ==> Release 1.0.0 (26 January 1994) <==
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1511 =======================================
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1512
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1513 As is traditional, so many things have changed that I can't pretend to
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1514 be complete in these release notes, but I'll try anyway :-)
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1515
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1516 Note that the very last section is labeled "remaining bugs".
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1517
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1518
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1519 Source organization and build process
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1520 -------------------------------------
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1521
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1522 * The sources have finally been split: instead of a single src
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1523 subdirectory there are now separate directories Include, Parser,
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1524 Grammar, Objects, Python and Modules. Other directories also start
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1525 with a capital letter: Misc, Doc, Lib, Demo.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1526
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1527 * A few extensions (notably Amoeba and X support) have been moved to a
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1528 separate subtree Extensions, which is no longer in the core
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1529 distribution, but separately ftp'able as extensions.tar.Z. (The
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1530 distribution contains a placeholder Ext-dummy with a description of
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1531 the Extensions subtree as well as the most recent versions of the
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1532 scripts used there.)
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1533
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1534 * A few large specialized demos (SGI video and www) have been
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1535 moved to a separate subdirectory Demo2, which is no longer in the core
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1536 distribution, but separately ftp'able as demo2.tar.Z.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1537
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1538 * Parts of the standard library have been moved to subdirectories:
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1539 there are now standard subdirectories stdwin, test, sgi and sun4.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1540
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1541 * The configuration process has radically changed: I now use GNU
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1542 autoconf. This makes it much easier to build on new Unix flavors, as
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1543 well as fully supporting VPATH (if your Make has it). The scripts
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1544 Configure.py and Addmodule.sh are no longer needed. Many source files
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1545 have been adapted in order to work with the symbols that the configure
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1546 script generated by autoconf defines (or not); the resulting source is
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1547 much more portable to different C compilers and operating systems,
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1548 even non Unix systems (a Mac port was done in an afternoon). See the
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1549 toplevel README file for a description of the new build process.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1550
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1551 * GNU readline (a slightly newer version) is now a subdirectory of the
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1552 Python toplevel. It is still not automatically configured (being
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1553 totally autoconf-unaware :-). One problem has been solved: typing
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1554 Control-C to a readline prompt will now work. The distribution no
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1555 longer contains a "super-level" directory (above the python toplevel
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1556 directory), and dl, dl-dld and GNU dld are no longer part of the
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1557 Python distribution (you can still ftp them from
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1558 ftp.cwi.nl:/pub/dynload).
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1559
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1560 * The DOS functions have been taken out of posixmodule.c and moved
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1561 into a separate file dosmodule.c.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1562
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1563 * There's now a separate file version.c which contains nothing but
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1564 the version number.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1565
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1566 * The actual main program is now contained in config.c (unless NO_MAIN
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1567 is defined); pythonmain.c now contains a function realmain() which is
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1568 called from config.c's main().
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1569
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1570 * All files needed to use the built-in module md5 are now contained in
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1571 the distribution. The module has been cleaned up considerably.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1572
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1573
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1574 Documentation
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1575 -------------
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1576
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1577 * The library manual has been split into many more small latex files,
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1578 so it is easier to edit Doc/lib.tex file to create a custom library
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1579 manual, describing only those modules supported on your system. (This
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1580 is not automated though.)
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1581
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1582 * A fourth manual has been added, titled "Extending and Embedding the
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1583 Python Interpreter" (Doc/ext.tex), which collects information about
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1584 the interpreter which was previously spread over several files in the
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1585 misc subdirectory.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1586
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1587 * The entire documentation is now also available on-line for those who
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1588 have a WWW browser (e.g. NCSA Mosaic). Point your browser to the URL
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1589 "http://www.cwi.nl/~guido/Python.html".

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1591
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1592 Syntax
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1593 ------
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1594
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1595 * Strings may now be enclosed in double quotes as well as in single
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1596 quotes. There is no difference in interpretation. The repr() of
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1597 string objects will use double quotes if the string contains a single
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1598 quote and no double quotes. Thanks to Amrit Prem for these changes!
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1599
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1600 * There is a new keyword 'exec'. This replaces the exec() built-in
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1601 function. If a function contains an exec statement, local variable
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1602 optimization is not performed for that particular function, thus
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1603 making assignment to local variables in exec statements less
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1604 confusing. (As a consequence, os.exec and python.exec have been

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1607 * There is a new keyword 'lambda'. An expression of the form
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1608
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1609 lambda <parameters> : <expression>

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1611 yields an anonymous function. This is really only syntactic sugar;
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1612 you can just as well define a local function using
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1613
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1614 def some_temporary_name(<parameters>): return <expression>

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1616 Lambda expressions are particularly useful in combination with map(),
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1617 filter() and reduce(), described below. Thanks to Amrit Prem for
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1618 submitting this code (as well as map(), filter(), reduce() and
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1619 xrange())!

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1625 * The built-in module containing the built-in functions is called
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1626 __builtin__ instead of builtin.

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1628 * New built-in functions map(), filter() and reduce() perform standard
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1629 functional programming operations (though not lazily):
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1630
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1631 - map(f, seq) returns a new sequence whose items are the items from
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1632 seq with f() applied to them.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1633
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1634 - filter(f, seq) returns a subsequence of seq consisting of those
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1635 items for which f() is true.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1636
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1637 - reduce(f, seq, initial) returns a value computed as follows:
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1638 acc = initial
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1639 for item in seq: acc = f(acc, item)
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1640 return acc

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1642 * New function xrange() creates a "range object". Its arguments are
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1643 the same as those of range(), and when used in a for loop a range
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1644 objects also behaves identical. The advantage of xrange() over
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1645 range() is that its representation (if the range contains many
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1646 elements) is much more compact than that of range(). The disadvantage
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1647 is that the result cannot be used to initialize a list object or for
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1648 the "Python idiom" [RED, GREEN, BLUE] = range(3). On some modern
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1649 architectures, benchmarks have shown that "for i in range(...): ..."
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1650 actually executes faster than "for i in xrange(...): ...", but on
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1651 memory starved machines like PCs running DOS range(100000) may be just
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1652 too big to be represented at all...

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1654 * Built-in function exec() has been replaced by the exec statement --
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1655 see above.

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1661 * Syntax errors are now not printed to stderr by the parser, but
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1662 rather the offending line and other relevant information are packed up
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1663 in the SyntaxError exception argument. When the main loop catches a
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1664 SyntaxError exception it will print the error in the same format as
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1665 previously, but at the proper position in the stack traceback.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1666
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1667 * You can now set a maximum to the number of traceback entries
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1668 printed by assigning to sys.tracebacklimit. The default is 1000.

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1670 * The version number in .pyc files has changed yet again.

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1672 * It is now possible to have a .pyc file without a corresponding .py
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1673 file. (Warning: this may break existing installations if you have an
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1674 old .pyc file lingering around somewhere on your module search path
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1675 without a corresponding .py file, when there is a .py file for a
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1676 module of the same name further down the path -- the new interpreter
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1677 will find the first .pyc file and complain about it, while the old
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1678 interpreter would ignore it and use the .py file further down.)
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1679
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1680 * The list sys.builtin_module_names is now sorted and also contains
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1681 the names of a few hardwired built-in modules (sys, __main__ and
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1682 __builtin__).
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1683
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1684 * A module can now find its own name by accessing the global variable
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1685 __name__. Assigning to this variable essentially renames the module
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1686 (it should also be stored under a different key in sys.modules).
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1687 A neat hack follows from this: a module that wants to execute a main
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1688 program when called as a script no longer needs to compare
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1689 sys.argv[0]; it can simply do "if __name__ == '__main__': main()".

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1691 * When an object is printed by the print statement, its implementation
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1692 of str() is used. This means that classes can define __str__(self) to
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1693 direct how their instances are printed. This is different from
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1694 __repr__(self), which should define an unambigous string
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1695 representation of the instance. (If __str__() is not defined, it
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1696 defaults to __repr__().)
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1697
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1698 * Functions and code objects can now be compared meaningfully.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1699
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1700 * On systems supporting SunOS or SVR4 style shared libraries, dynamic
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1701 loading of modules using shared libraries is automatically configured.

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1708 * File objects have acquired a new method writelines() which is the
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1709 reverse of readlines(). (It does not actually write lines, just a
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1710 list of strings, but the symmetry makes the choice of name OK.)

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1716 * Socket objects no longer support the avail() method. Use the select
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1717 module instead, or use this function to replace it:

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1723 * Initialization of stdwin is done differently. It actually modifies
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1724 sys.argv (taking out the options the X version of stdwin recognizes)
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1725 the first time it is imported.

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1727 * A new built-in module parser provides a rudimentary interface to the
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1728 python parser. Corresponding standard library modules token and symbol

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1731 * The posix module has aquired new functions setuid(), setgid(),
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1732 execve(), and exec() has been renamed to execv().

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1734 * The array module is extended with 8-byte object swaps, the 'i'
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1735 format character, and a reverse() method. The read() and write()
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1736 methods are renamed to fromfile() and tofile().

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1738 * The rotor module has freed of portability bugs. This introduces a
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1739 backward compatibility problem: strings encoded with the old rotor
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1740 module can't be decoded by the new version.

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1742 * For select.select(), a timeout (4th) argument of None means the same

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1745 * Module strop (and hence standard library module string) has aquired
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1746 a new function: rindex(). Thanks to Amrit Prem!

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1748 * Module regex defines a new function symcomp() which uses an extended
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1749 regular expression syntax: parenthesized subexpressions may be labeled
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1750 using the form "$<labelname>...$", and the group() method can return
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1751 sub-expressions by name. Thanks to Tracy Tims for these changes!

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1759
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1760 * The library is now split in several subdirectories: all stuff using
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1761 stdwin is in Lib/stdwin, all SGI specific (or SGI Indigo or GL) stuff
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1762 is in Lib/sgi, all Sun Sparc specific stuff is in Lib/sun4, and all
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1763 test modules are in Lib/test. The default module search path will
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1764 include all relevant subdirectories by default.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1765
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1766 * Module os now knows about trying to import dos. It defines
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1767 functions execl(), execle(), execlp() and execvp().
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1768
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1769 * New module dospath (should be attacked by a DOS hacker though).
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1770
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1771 * All modules defining classes now define __init__() constructors
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1772 instead of init() methods. THIS IS AN INCOMPATIBLE CHANGE!
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1773
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1774 * Some minor changes and bugfixes module ftplib (mostly Steve
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1775 Majewski's suggestions); the debug() method is renamed to
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1776 set_debuglevel().
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1777
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1778 * Some new test modules (not run automatically by testall though):
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1779 test_audioop, test_md5, test_rgbimg, test_select.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1780
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1781 * Module string now defines rindex() and rfind() in analogy of index()
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1782 and find(). It also defines atof() and atol() (and corresponding
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1783 exceptions) in analogy to atoi().
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1784
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1785 * Added help() functions to modules profile and pdb.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1786
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1787 * The wdb debugger (now in Lib/stdwin) now shows class or instance
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1788 variables on a double click. Thanks to Sjoerd Mullender!
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1789
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1790 * The (undocumented) module lambda has gone -- you couldn't import it
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1791 any more, and it was basically more a demo than a library module...
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1792
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1793

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1797 * The optional built-in modules audioop and imageop are now standard
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1798 parts of the interpreter. Thanks to Sjoerd Mullender and Jack Jansen
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1799 for contributing this code!
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1800
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1801 * There's a new operation in audioop: minmax().
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1802
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1803 * There's a new built-in module called rgbimg which supports portable
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1804 efficient reading of SGI RCG image files. Thanks also to Paul
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1805 Haeberli for the original code! (Who will contribute a GIF reader?)
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1806
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1807 * The module aifc is gone -- you should now always use aifc, which has
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1808 received a facelift.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1809
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1810 * There's a new module sunau., for reading Sun (and NeXT) audio files.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1811
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1812 * There's a new module audiodev which provides a uniform interface to
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1813 (SGI Indigo and Sun Sparc) audio hardware.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1814
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1815 * There's a new module sndhdr which recognizes various sound files by
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1816 looking in their header and checking for various magic words.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1817

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1819 Optimizations
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1820 -------------
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1821
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1822 * Most optimizations below can be configured by compile-time flags.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1823 Thanks to Sjoerd Mullender for submitting these optimizations!
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1824
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1825 * Small integers (default -1..99) are shared -- i.e. if two different
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1826 functions compute the same value it is possible (but not
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1827 guaranteed!!!) that they return the same object. Python programs
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1828 can detect this but should never rely on it.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1829
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1830 * Empty tuples (which all compare equal) are shared in the same
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1831 manner.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1832
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1833 * Tuples of size up to 20 (default) are put in separate free lists
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1834 when deallocated.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1835
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1836 * There is a compile-time option to cache a string's hash function,
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1837 but this appeared to have a negligeable effect, and as it costs 4
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1838 bytes per string it is disabled by default.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1839
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1840

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1842 ----------------
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1843
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1844 * The initialization interface has been simplified somewhat. You now
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1845 only call "initall()" to initialize the interpreter.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1846
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1847 * The previously announced renaming of externally visible identifiers
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1848 has not been carried out. It will happen in a later release. Sorry.

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1851 Miscellaneous bugs that have been fixed
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1852 ---------------------------------------
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1853
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1854 * All known portability bugs.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1855
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1856 * Version 0.9.9 dumped core in <listobject>.sort() which has been
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1857 fixed. Thanks to Jaap Vermeulen for fixing this and posting the fix
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1858 on the mailing list while I was away!
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1859
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1860 * Core dump on a format string ending in '%', e.g. in the expression
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1861 '%' % None.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1862
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1863 * The array module yielded a bogus result for concatenation (a+b would
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1864 yield a+a).
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1865
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1866 * Some serious memory leaks in strop.split() and strop.splitfields().
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1867
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1868 * Several problems with the nis module.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1869
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1870 * Subtle problem when copying a class method from another class
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1871 through assignment (the method could not be called).

9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1874 Remaining bugs
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1875 --------------
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1876
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1877 * One problem with 64-bit machines remains -- since .pyc files are
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1878 portable and use only 4 bytes to represent an integer object, 64-bit
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1879 integer literals are silently truncated when written into a .pyc file.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1880 Work-around: use eval('123456789101112').
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1881
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1882 * The freeze script doesn't work any more. A new and more portable
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1883 one can probably be cooked up using tricks from Extensions/mkext.py.
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1884
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1885 * The dos support hasn't been tested yet. (Really Soon Now we should
9bcac8da0262 Moved older news to HISTORY file Guido van Rossum <guido@python.org> parents: 1529 diff changeset	1886 have a PC with a working C compiler!)

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1892
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1893 I believe these are the main user-visible changes in this release,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1894 but there may be others. SGI users may scan the {src,lib}/ChangeLog
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1895 files for improvements of some SGI specific modules, e.g. aifc and
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1896 cl. Developers of extension modules should also read src/ChangeLog.

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1901
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1902 * This is the last release using the current naming conventions. New
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1903 naming conventions are explained in the file misc/NAMING.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1904 Summarizing, all externally visible symbols get (at least) a "Py"
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1905 prefix, and most functions are renamed to the standard form
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1906 PyModule_FunctionName.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1907
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1908 * Writers of extensions are urged to start using the new naming
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1909 conventions. The next release will use the new naming conventions
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1910 throughout (it will also have a different source directory
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1911 structure).

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1913 * As a result of the preliminary work for the great renaming, many
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1914 functions that were accidentally global have been made static.

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1917 BETA X11 support
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1918 ----------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1919
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1920 * There are now modules interfacing to the X11 Toolkit Intrinsics, the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1921 Athena widgets, and the Motif 1.1 widget set. These are not yet
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1922 documented except through the examples and README file in the demo/x11
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1923 directory. It is expected that this interface will be replaced by a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1924 more powerful and correct one in the future, which may or may not be
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1925 backward compatible. In other words, this part of the code is at most
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1926 BETA level software! (Note: the rest of Python is rock solid as ever!)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1927
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1928 * I understand that the above may be a bit of a disappointment,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1929 however my current schedule does not allow me to change this situation
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1930 before putting the release out of the door. By releasing it
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1931 undocumented and buggy, at least some of the (working!) demo programs,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1932 like itr (my Internet Talk Radio browser) become available to a larger
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1933 audience.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1934
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1935 * There are also modules interfacing to SGI's "Glx" widget (a GL
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1936 window wrapped in a widget) and to NCSA's "HTML" widget (which can
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1937 format HyperText Markup Language, the document format used by the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1938 World Wide Web).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1939
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1940 * I've experienced some problems when building the X11 support. In
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1941 particular, the Xm and Xaw widget sets don't go together, and it
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1942 appears that using X11R5 is better than using X11R4. Also the threads
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1943 module and its link time options may spoil things. My own strategy is
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1944 to build two Python binaries: one for use with X11 and one without
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1945 it, which can contain a richer set of built-in modules. Don't even
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1946 think of loading the X11 modules dynamically...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1947

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1949 Environmental changes
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1950 ---------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1951
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1952 * Compiled files (*.pyc files) created by this Python version are
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1953 incompatible with those created by the previous version. Both
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1954 versions detect this and silently create a correct version, but it
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1955 means that it is not a good idea to use the same library directory for
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1956 an old and a new interpreter, since they will start to "fight" over
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1957 the *.pyc files...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1958
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1959 * When a stack trace is printed, the exception is printed last instead
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1960 of first. This means that if the beginning of the stack trace
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1961 scrolled out of your window you can still see what exception caused
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1962 it.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1963
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1964 * Sometimes interrupting a Python operation does not work because it
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1965 hangs in a blocking system call. You can now kill the interpreter by
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1966 interrupting it three times. The second time you interrupt it, a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1967 message will be printed telling you that the third interrupt will kill
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1968 the interpreter. The "sys.exitfunc" feature still makes limited
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1969 clean-up possible in this case.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1970
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1971
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1972 Changes to the command line interface
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1973 -------------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1974
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1975 * The python usage message is now much more informative.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1976
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1977 * New option -i enters interactive mode after executing a script --
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1978 useful for debugging.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1979
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1980 * New option -k raises an exception when an expression statement
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1981 yields a value other than None.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1982
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1983 * For each option there is now also a corresponding environment
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1984 variable.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1985
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1986
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1987 Using Python as an embedded language
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1988 ------------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1989
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1990 * The distribution now contains (some) documentation on the use of
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1991 Python as an "embedded language" in other applications, as well as a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1992 simple example. See the file misc/EMBEDDING and the directory embed/.

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1995 Speed improvements
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1996 ------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1997
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1998 * Function local variables are now generally stored in an array and
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	1999 accessed using an integer indexing operation, instead of through a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2000 dictionary lookup. (This compensates the somewhat slower dictionary
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2001 lookup caused by the generalization of the dictionary module.)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2002
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2003
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2004 Changes to the syntax
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2005 ---------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2006
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2007 * Continuation lines can now sometimes be written without a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2008 backslash: if the continuation is contained within nesting (), [] or
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2009 {} brackets the \ may be omitted. There's a much improved
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2010 python-mode.el in the misc directory which knows about this as well.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2011
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2012 * You can no longer use an empty set of parentheses to define a class
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2013 without base classes. That is, you no longer write this:
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2014
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2015 class Foo(): # syntax error
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2016 ...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2017
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2018 You must write this instead:
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2019
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2020 class Foo:
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2021 ...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2022
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2023 This was already the preferred syntax in release 0.9.8 but many
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2024 people seemed not to have picked it up. There's a Python script that
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2025 fixes old code: demo/scripts/classfix.py.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2026
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2027 * There's a new reserved word: "access". The syntax and semantics are
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2028 still subject of of research and debate (as well as undocumented), but
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2029 the parser knows about the keyword so you must not use it as a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2030 variable, function, or attribute name.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2031
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2032
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2033 Changes to the semantics of the language proper
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2034 -----------------------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2035
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2036 * The following compatibility hack is removed: if a function was
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2037 defined with two or more arguments, and called with a single argument
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2038 that was a tuple with just as many arguments, the items of this tuple
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2039 would be used as the arguments. This is no longer supported.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2040
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2041
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2042 Changes to the semantics of classes and instances
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2043 -------------------------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2044
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2045 * Class variables are now also accessible as instance variables for
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2046 reading (assignment creates an instance variable which overrides the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2047 class variable of the same name though).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2048
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2049 * If a class attribute is a user-defined function, a new kind of
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2050 object is returned: an "unbound method". This contains a pointer to
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2051 the class and can only be called with a first argument which is a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2052 member of that class (or a derived class).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2053
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2054 * If a class defines a method __init__(self, arg1, ...) then this
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2055 method is called when a class instance is created by the classname()
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2056 construct. Arguments passed to classname() are passed to the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2057 __init__() method. The __init__() methods of base classes are not
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2058 automatically called; the derived __init__() method must call these if
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2059 necessary (this was done so the derived __init__() method can choose
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2060 the call order and arguments for the base __init__() methods).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2061
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2062 * If a class defines a method __del__(self) then this method is called
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2063 when an instance of the class is about to be destroyed. This makes it
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2064 possible to implement clean-up of external resources attached to the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2065 instance. As with __init__(), the __del__() methods of base classes
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2066 are not automatically called. If __del__ manages to store a reference
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2067 to the object somewhere, its destruction is postponed; when the object
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2068 is again about to be destroyed its __del__() method will be called
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2069 again.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2070
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2071 * Classes may define a method __hash__(self) to allow their instances
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2072 to be used as dictionary keys. This must return a 32-bit integer.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2073
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2074
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2075 Minor improvements
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2076 ------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2077
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2078 * Function and class objects now know their name (the name given in
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2079 the 'def' or 'class' statement that created them).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2080
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2081 * Class instances now know their class name.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2082
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2083
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2084 Additions to built-in operations
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2085 --------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2086
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2087 * The % operator with a string left argument implements formatting
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2088 similar to sprintf() in C. The right argument is either a single
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2089 value or a tuple of values. All features of Standard C sprintf() are
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2090 supported except %p.

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2092 * Dictionaries now support almost any key type, instead of just
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2093 strings. (The key type must be an immutable type or must be a class
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2094 instance where the class defines a method __hash__(), in order to
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2095 avoid losing track of keys whose value may change.)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2096
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2097 * Built-in methods are now compared properly: when comparing x.meth1
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2098 and y.meth2, if x is equal to y and the methods are defined by the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2099 same function, x.meth1 compares equal to y.meth2.

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2101
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2102 Additions to built-in functions
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2103 -------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2104
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2105 * str(x) returns a string version of its argument. If the argument is
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2106 a string it is returned unchanged, otherwise it returns `x`.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2107
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2108 * repr(x) returns the same as `x`. (Some users found it easier to
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2109 have this as a function.)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2110
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2111 * round(x) returns the floating point number x rounded to an whole
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2112 number, represented as a floating point number. round(x, n) returns x
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2113 rounded to n digits.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2114
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2115 * hasattr(x, name) returns true when x has an attribute with the given
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2116 name.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2117
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2118 * hash(x) returns a hash code (32-bit integer) of an arbitrary
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2119 immutable object's value.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2120
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2121 * id(x) returns a unique identifier (32-bit integer) of an arbitrary
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2122 object.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2123
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2124 * compile() compiles a string to a Python code object.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2125
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2126 * exec() and eval() now support execution of code objects.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2127
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2128
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2129 Changes to the documented part of the library (standard modules)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2130 ----------------------------------------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2131
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2132 * os.path.normpath() (a.k.a. posixpath.normpath()) has been fixed so
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2133 the border case '/foo/..' returns '/' instead of ''.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2134
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2135 * A new function string.find() is added with similar semantics to
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2136 string.index(); however when it does not find the given substring it
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2137 returns -1 instead of raising string.index_error.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2138
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2139
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2140 Changes to built-in modules
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2141 ---------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2142
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2143 * New optional module 'array' implements operations on sequences of
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2144 integers or floating point numbers of a particular size. This is
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2145 useful to manipulate large numerical arrays or to read and write
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2146 binary files consisting of numerical data.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2147
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2148 * Regular expression objects created by module regex now support a new
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2149 method named group(), which returns one or more $...$ groups by number.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2150 The number of groups is increased from 10 to 100.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2151
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2152 * Function compile() in module regex now supports an optional mapping
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2153 argument; a variable casefold is added to the module which can be used
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2154 as a standard uppercase to lowercase mapping.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2155
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2156 * Module time now supports many routines that are defined in the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2157 Standard C time interface (<time.h>): gmtime(), localtime(),
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2158 asctime(), ctime(), mktime(), as well as these variables (taken from
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2159 System V): timezone, altzone, daylight and tzname. (The corresponding
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2160 functions in the undocumented module calendar have been removed; the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2161 undocumented and unfinished module tzparse is now obsolete and will
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2162 disappear in a future release.)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2163
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2164 * Module strop (the fast built-in version of standard module string)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2165 now uses C's definition of whitespace instead of fixing it to space,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2166 tab and newline; in practice this usually means that vertical tab,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2167 form feed and return are now also considered whitespace. It exports
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2168 the string of characters that are considered whitespace as well as the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2169 characters that are considered lowercase or uppercase.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2170
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2171 * Module sys now defines the variable builtin_module_names, a list of
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2172 names of modules built into the current interpreter (including not
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2173 yet imported, but excluding two special modules that always have to be
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2174 defined -- sys and builtin).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2175
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2176 * Objects created by module sunaudiodev now also support flush() and
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2177 close() methods.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2178
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2179 * Socket objects created by module socket now support an optional
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2180 flags argument for their methods sendto() and recvfrom().
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2181
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2182 * Module marshal now supports dumping to and loading from strings,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2183 through the functions dumps() and loads().
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2184
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2185 * Module stdwin now supports some new functionality. You may have to
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2186 ftp the latest version: ftp.cwi.nl:/pub/stdwin/stdwinforviews.tar.Z.)

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2188
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2189 Bugs fixed
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2190 ----------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2191
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2192 * Fixed comparison of negative long integers.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2193
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2194 * The tokenizer no longer botches input lines longer than BUFSIZ.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2195
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2196 * Fixed several severe memory leaks in module select.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2197
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2198 * Fixed memory leaks in modules socket and sv.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2199
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2200 * Fixed memory leak in divmod() for long integers.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2201
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2202 * Problems with definition of floatsleep() on Suns fixed.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2203
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2204 * Many portability bugs fixed (and undoubtedly new ones added :-).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2205
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2206
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2207 Changes to the build procedure
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2208 ------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2209
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2210 * The Makefile supports some new targets: "make default" and "make
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2211 all". Both are by normally equivalent to "make python".
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2212
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2213 * The Makefile no longer uses $> since it's not supported by all
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2214 versions of Make.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2215
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2216 * The header files now all contain #ifdef constructs designed to make
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2217 it safe to include the same header file twice, as well as support for
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2218 inclusion from C++ programs (automatic extern "C" { ... } added).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2219
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2220
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2221 Freezing Python scripts
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2222 -----------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2223
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2224 * There is now some support for "freezing" a Python script as a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2225 stand-alone executable binary file. See the script
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2226 demo/scripts/freeze.py. It will require some site-specific tailoring
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2227 of the script to get this working, but is quite worthwhile if you write
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2228 Python code for other who may not have built and installed Python.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2229
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2230
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2231 MS-DOS
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2232 ------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2233
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2234 * A new MS-DOS port has been done, using MSC 6.0 (I believe). Thanks,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2235 Marcel van der Peijl! This requires fewer compatibility hacks in
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2236 posixmodule.c. The executable is not yet available but will be soon
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2237 (check the mailing list).

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2271 There's only one big change: the conformance checking for function
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2272 argument lists (of user-defined functions only) is stricter. Earlier,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2273 you could get away with the following:

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2275 (a) define a function of one argument and call it with any
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2276 number of arguments; if the actual argument count wasn't
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2277 one, the function would receive a tuple containing the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2278 arguments arguments (an empty tuple if there were none).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2279
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2280 (b) define a function of two arguments, and call it with more
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2281 than two arguments; if there were more than two arguments,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2282 the second argument would be passed as a tuple containing
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2283 the second and further actual arguments.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2284
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2285 (Note that an argument (formal or actual) that is a tuple is counted as
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2286 one; these rules don't apply inside such tuples, only at the top level
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2287 of the argument list.)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2288
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2289 Case (a) was needed to accommodate variable-length argument lists;
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2290 there is now an explicit "varargs" feature (precede the last argument
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2291 with a '*'). Case (b) was needed for compatibility with old class
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2292 definitions: up to release 0.9.4 a method with more than one argument
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2293 had to be declared as "def meth(self, (arg1, arg2, ...)): ...".
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2294 Version 0.9.6 provide better ways to handle both casees, bot provided
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2295 backward compatibility; version 0.9.8 retracts the compatibility hacks
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2296 since they also cause confusing behavior if a function is called with
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2297 the wrong number of arguments.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2298
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2299 There's a script that helps converting classes that still rely on (b),
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2300 provided their methods' first argument is called "self":
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2301 demo/scripts/methfix.py.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2302
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2303 If this change breaks lots of code you have developed locally, try
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2304 #defining COMPAT_HACKS in ceval.c.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2305
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2306 (There's a third compatibility hack, which is the reverse of (a): if a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2307 function is defined with two or more arguments, and called with a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2308 single argument that is a tuple with just as many arguments, the items
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2309 of this tuple will be used as the arguments. Although this can (and
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2310 should!) be done using the built-in function apply() instead, it isn't
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2311 withdrawn yet.)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2312
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2313
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2314 One minor change: comparing instance methods works like expected, so
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2315 that if x is an instance of a user-defined class and has a method m,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2316 then (x.m==x.m) yields 1.

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2318
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2319 The following was already present in 0.9.7beta, but not explicitly
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2320 mentioned in the NEWS file: user-defined classes can now define types
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2321 that behave in almost allrespects like numbers. See
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2322 demo/classes/Rat.py for a simple example.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2323
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2324
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2325 Changes to the build process
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2326 ----------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2327
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2328 The Configure.py script and the Makefile has been made somewhat more
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2329 bullet-proof, after reports of (minor) trouble on certain platforms.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2330
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2331 There is now a script to patch Makefile and config.c to add a new
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2332 optional built-in module: Addmodule.sh. Read the script before using!
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2333
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2334 Useing Addmodule.sh, all optional modules can now be configured at
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2335 compile time using Configure.py, so there are no modules left that
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2336 require dynamic loading.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2337
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2338 The Makefile has been fixed to make it easier to use with the VPATH
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2339 feature of some Make versions (e.g. SunOS).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2340
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2341
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2342 Changes affecting portability
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2343 -----------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2344
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2345 Several minor portability problems have been solved, e.g. "malloc.h"
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2346 has been renamed to "mymalloc.h", "strdup.c" is no longer used, and
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2347 the system now tolerates malloc(0) returning 0.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2348
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2349 For dynamic loading on the SGI, Jack Jansen's dl 1.6 is now
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2350 distributed with Python. This solves several minor problems, in
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2351 particular scripts invoked using #! can now use dynamic loading.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2352
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2353
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2354 Changes to the interpreter interface
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2355 ------------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2356
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2357 On popular demand, there's finally a "profile" feature for interactive
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2358 use of the interpreter. If the environment variable $PYTHONSTARTUP is
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2359 set to the name of an existing file, Python statements in this file
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2360 are executed when the interpreter is started in interactive mode.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2361
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2362 There is a new clean-up mechanism, complementing try...finally: if you
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2363 assign a function object to sys.exitfunc, it will be called when
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2364 Python exits or receives a SIGTERM or SIGHUP signal.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2365
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2366 The interpreter is now generally assumed to live in
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2367 /usr/local/bin/python (as opposed to /usr/local/python). The script
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2368 demo/scripts/fixps.py will update old scripts in place (you can easily
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2369 modify it to do other similar changes).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2370
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2371 Most I/O that uses sys.stdin/stdout/stderr will now use any object
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2372 assigned to those names as long as the object supports readline() or
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2373 write() methods.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2374
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2375 The parser stack has been increased to 500 to accommodate more
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2376 complicated expressions (7 levels used to be the practical maximum,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2377 it's now about 38).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2378
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2379 The limit on the size of the run-time stack has completely been
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2380 removed -- this means that tuple or list displays can contain any
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2381 number of elements (formerly more than 50 would crash the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2382 interpreter).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2383
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2384
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2385 Changes to existing built-in functions and methods
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2386 --------------------------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2387
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2388 The built-in functions int(), long(), float(), oct() and hex() now
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2389 also apply to class instalces that define corresponding methods
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2390 (__int__ etc.).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2391
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2392
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2393 New built-in functions
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2394 ----------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2395
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2396 The new functions str() and repr() convert any object to a string.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2397 The function repr(x) is in all respects equivalent to `x` -- some
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2398 people prefer a function for this. The function str(x) does the same
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2399 except if x is already a string -- then it returns x unchanged
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2400 (repr(x) adds quotes and escapes "funny" characters as octal escapes).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2401
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2402 The new function cmp(x, y) returns -1 if x<y, 0 if x==y, 1 if x>y.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2403
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2404
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2405 Changes to general built-in modules
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2406 -----------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2407
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2408 The time module's functions are more general: time() returns a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2409 floating point number and sleep() accepts one. Their accuracies
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2410 depends on the precision of the system clock. Millisleep is no longer
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2411 needed (although it still exists for now), but millitimer is still
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2412 needed since on some systems wall clock time is only available with
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2413 seconds precision, while a source of more precise time exists that
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2414 isn't synchronized with the wall clock. (On UNIX systems that support
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2415 the BSD gettimeofday() function, time.time() is as time.millitimer().)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2416
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2417 The string representation of a file object now includes an address:
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2418 '<file 'filename', mode 'r' at #######>' where ###### is a hex number
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2419 (the object's address) to make it unique.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2420
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2421 New functions added to posix: nice(), setpgrp(), and if your system
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2422 supports them: setsid(), setpgid(), tcgetpgrp(), tcsetpgrp().
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2423
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2424 Improvements to the socket module: socket objects have new methods
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2425 getpeername() and getsockname(), and the {get,set}sockopt methods can
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2426 now get/set any kind of option using strings built with the new struct
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2427 module. And there's a new function fromfd() which creates a socket
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2428 object given a file descriptor (useful for servers started by inetd,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2429 which have a socket connected to stdin and stdout).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2430
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2431
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2432 Changes to SGI-specific built-in modules
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2433 ----------------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2434
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2435 The FORMS library interface (fl) now requires FORMS 2.1a. Some new
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2436 functions have been added and some bugs have been fixed.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2437
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2438 Additions to al (audio library interface): added getname(),
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2439 getdefault() and getminmax().
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2440
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2441 The gl modules doesn't call "foreground()" when initialized (this
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2442 caused some problems) like it dit in 0.9.7beta (but not before).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2443 There's a new gl function 'gversion() which returns a version string.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2444
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2445 The interface to sv (Indigo video interface) has totally changed.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2446 (Sorry, still no documentation, but see the examples in
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2447 demo/sgi/{sv,video}.)

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2450 Changes to standard library modules
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2451 -----------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2452
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2453 Most functions in module string are now much faster: they're actually
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2454 implemented in C. The module containing the C versions is called
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2455 "strop" but you should still import "string" since strop doesn't
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2456 provide all the interfaces defined in string (and strop may be renamed
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2457 to string when it is complete in a future release).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2458
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2459 string.index() now accepts an optional third argument giving an index
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2460 where to start searching in the first argument, so you can find second
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2461 and further occurrences (this is similar to the regular expression
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2462 functions in regex).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2463
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2464 The definition of what string.splitfields(anything, '') should return
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2465 is changed for the last time: it returns a singleton list containing
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2466 its whole first argument unchanged. This is compatible with
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2467 regsub.split() which also ignores empty delimiter matches.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2468
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2469 posixpath, macpath: added dirname() and normpath() (and basename() to
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2470 macpath).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2471
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2472 The mainloop module (for use with stdwin) can now demultiplex input
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2473 from other sources, as long as they can be polled with select().
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2474
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2475
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2476 New built-in modules
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2477 --------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2478
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2479 Module struct defines functions to pack/unpack values to/from strings
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2480 representing binary values in native byte order.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2481
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2482 Module strop implements C versions of many functions from string (see
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2483 above).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2484
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2485 Optional module fcntl defines interfaces to fcntl() and ioctl() --
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2486 UNIX only. (Not yet properly documented -- see however src/fcntl.doc.)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2487
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2488 Optional module mpz defines an interface to an altaernative long
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2489 integer implementation, the GNU MPZ library.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2490
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2491 Optional module md5 uses the GNU MPZ library to calculate MD5
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2492 signatures of strings.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2493
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2494 There are also optional new modules specific to SGI machines: imageop
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2495 defines some simple operations to images represented as strings; sv
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2496 interfaces to the Indigo video board; cl interfaces to the (yet
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2497 unreleased) compression library.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2498
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2499
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2500 New standard library modules
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2501 ----------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2502
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2503 (Unfortunately the following modules are not all documented; read the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2504 sources to find out more about them!)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2505
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2506 autotest: run testall without showing any output unless it differs
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2507 from the expected output

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2512 <-> YUV)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2513

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2520 awk functions of the same name: sub() and gsub() do string
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2521 substitution, split() splits a string using a regular expression to
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2522 define how separators are define.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2523
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2524 test_types: test operations on the built-in types of Python
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2525
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2526 toaiff: convert various audio file formats to AIFF format
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2527
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2528 tzparse: parse the TZ environment parameter (this may be less general
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2529 than it could be, let me know if you fix it).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2530
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2531 (Note that the obsolete module "path" no longer exists.)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2532
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2533
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2534 New SGI-specific library modules
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2535 --------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2536
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2537 CL: constants for use with the built-in compression library interface (cl)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2538
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2539 Queue: a multi-producer, multi-consumer queue class implemented for
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2540 use with the built-in thread module
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2541
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2542 SOCKET: constants for use with built-in module socket, e.g. to set/get
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2543 socket options. This is SGI-specific because the constants to be
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2544 passed are system-dependent. You can generate a version for your own
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2545 system by running the script demo/scripts/h2py.py with
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2546 /usr/include/sys/socket.h as input.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2547

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2551
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2552
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2553 New demos
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2554 ---------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2555
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2556 There's an experimental interface to define Sun RPC clients and
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2557 servers in demo/rpc.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2558
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2559 There's a collection of interfaces to WWW, WAIS and Gopher (both
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2560 Python classes and program providing a user interface) in demo/www.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2561 This includes a program texi2html.py which converts texinfo files to
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2562 HTML files (the format used hy WWW).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2563
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2564 The ibrowse demo has moved from demo/stdwin/ibrowse to demo/ibrowse.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2565
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2566 For SGI systems, there's a whole collection of programs and classes
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2567 that make use of the Indigo video board in demo/sgi/{sv,video}. This
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2568 represents a significant amount of work that we're giving away!
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2569
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2570 There are demos "rsa" and "md5test" that exercise the mpz and md5
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2571 modules, respectively. The rsa demo is a complete implementation of
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2572 the RSA public-key cryptosystem!
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2573
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2574 A bunch of games and examples submitted by Stoffel Erasmus have been
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2575 included in demo/stoffel.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2576
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2577 There are miscellaneous new files in some existing demo
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2578 subdirectories: classes/bitvec.py, scripts/{fixps,methfix}.py,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2579 sgi/al/cmpaf.py, sockets/{mcast,gopher}.py.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2580
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2581 There are also many minor changes to existing files, but I'm too lazy
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2582 to run a diff and note the differences -- you can do this yourself if
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2583 you save the old distribution's demos. One highlight: the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2584 stdwin/python.py demo is much improved!
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2585
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2586
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2587 Changes to the documentation
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2588 ----------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2589
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2590 The LaTeX source for the library uses different macros to enable it to
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2591 be converted to texinfo, and from there to INFO or HTML format so it
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2592 can be browsed as a hypertext. The net result is that you can now
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2593 read the Python library documentation in Emacs info mode!
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2594
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2595
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2596 Changes to the source code that affect C extension writers

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2598
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2599 The function strdup() no longer exists (it was used only in one places
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2600 and is somewhat of a a portability problem sice some systems have the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2601 same function in their C library.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2602
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2603 The functions NEW() and RENEW() allocate one spare byte to guard
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2604 against a NULL return from malloc(0) being taken for an error, but
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2605 this should not be relied upon.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2606
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2607
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2608 =========================
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2609 ==> Release 0.9.7beta <==

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2613 Changes to the language proper
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2614 ------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2615
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2616 User-defined classes can now implement operations invoked through
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2617 special syntax, such as x[i] or `x` by defining methods named
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2618 __getitem__(self, i) or __repr__(self), etc.

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2622 ----------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2623
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2624 Instead of extensive manual editing of the Makefile to select
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2625 compile-time options, you can now run a Configure.py script.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2626 The Makefile as distributed builds a minimal interpreter sufficient to
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2627 run Configure.py. See also misc/BUILD
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2628
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2629 The Makefile now includes more "utility" targets, e.g. install and

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2855
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2856 New features in 0.9.6:
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2857 - stricter try stmt syntax: cannot mix except and finally clauses on 1 try
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2858 - New module 'os' supplants modules 'mac' and 'posix' for most cases;
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2859 module 'path' is replaced by 'os.path'
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2860 - os.path.split() return value differs from that of old path.split()
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2861 - sys.exc_type, sys.exc_value, sys.exc_traceback are set to the exception
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2862 currently being handled
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2863 - sys.last_type, sys.last_value, sys.last_traceback remember last unhandled
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2864 exception
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2865 - New function string.expandtabs() expands tabs in a string
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2866 - Added times() interface to posix (user & sys time of process & children)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2867 - Added uname() interface to posix (returns OS type, hostname, etc.)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2868 - New built-in function execfile() is like exec() but from a file
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2869 - Functions exec() and eval() are less picky about whitespace/newlines
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2870 - New built-in functions getattr() and setattr() access arbitrary attributes
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2871 - More generic argument handling in built-in functions (see "./EXTENDING")
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2872 - Dynamic loading of modules written in C or C++ (see "./DYNLOAD")
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2873 - Division and modulo for long and plain integers with negative operands
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2874 have changed; a/b is now floor(float(a)/float(b)) and a%b is defined
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2875 as a-(a/b)*b. So now the outcome of divmod(a,b) is the same as
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2876 (a/b, a%b) for integers. For floats, % is also changed, but of course
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2877 / is unchanged, and divmod(x,y) does not yield (x/y, x%y)...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2878 - A function with explicit variable-length argument list can be declared
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2879 like this: def f(args): ...; or even like this: def f(a, b, rest): ...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2880 - Code tracing and profiling features have been added, and two source
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2881 code debuggers are provided in the library (pdb.py, tty-oriented,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2882 and wdb, window-oriented); you can now step through Python programs!
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2883 See sys.settrace() and sys.setprofile(), and "../lib/pdb.doc"
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2884 - '==' is now the only equality operator; "../demo/scripts/eqfix.py" is
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2885 a script that fixes old Python modules
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2886 - Plain integer right shift now uses sign extension

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2888 to give more useful results for negative operands
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2889 - Changed/added range checks for long/plain integer shifts
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2890 - Options found after "-c command" are now passed to the command in sys.argv
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2891 (note subtle incompatiblity with "python -c command -- -options"!)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2892 - Module stdwin is better protected against touching objects after they've
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2893 been closed; menus can now also be closed explicitly
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2894 - Stdwin now uses its own exception (stdwin.error)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2895
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2896 New features in 0.9.5 (released as Macintosh application only, 2 Jan 1992):
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2897 - dictionary objects can now be compared properly; e.g., {}=={} is true
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2898 - new exception SystemExit causes termination if not caught;
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2899 it is raised by sys.exit() so that 'finally' clauses can clean up,
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2900 and it may even be caught. It does work interactively!
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2901 - new module "regex" implements GNU Emacs style regular expressions;
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2902 module "regexp" is rewritten in Python for backward compatibility
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2903 - formal parameter lists may contain trailing commas
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2904
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2905 Bugs fixed in 0.9.6:
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2906 - assigning to or deleting a list item with a negative index dumped core
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2907 - divmod(-10L,5L) returned (-3L, 5L) instead of (-2L, 0L)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2908
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2909 Bugs fixed in 0.9.5:
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2910 - masking operations involving negative long integers gave wrong results
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2911
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2912
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2913 ===================================
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2914 ==> RELEASE 0.9.4 (24 Dec 1991) <==
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2915 ===================================
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2916
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2917 - new function argument handling (see below)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2918 - built-in apply(func, args) means func(args[0], args[1], ...)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2919 - new, more refined exceptions
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2920 - new exception string values (NameError = 'NameError' etc.)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2921 - better checking for math exceptions
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2922 - for sequences (string/tuple/list), x[-i] is now equivalent to x[len(x)-i]
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2923 - fixed list assignment bug: "a[1:1] = a" now works correctly
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2924 - new class syntax, without extraneous parentheses
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2925 - new 'global' statement to assign global variables from within a function
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2926
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2927
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2928 New class syntax
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2929 ----------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2930
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2931 You can now declare a base class as follows:
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2932
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2933 class B: # Was: class B():
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2934 def some_method(self): ...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2935 ...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2936
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2937 and a derived class thusly:
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2938
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2939 class D(B): # Was: class D() = B():
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2940 def another_method(self, arg): ...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2941
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2942 Multiple inheritance looks like this:
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2943
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2944 class M(B, D): # Was: class M() = B(), D():
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2945 def this_or_that_method(self, arg): ...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2946
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2947 The old syntax is still accepted by Python 0.9.4, but will disappear
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2948 in Python 1.0 (to be posted to comp.sources).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2949
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2950
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2951 New 'global' statement
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2952 ----------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2953
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2954 Every now and then you have a global variable in a module that you
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2955 want to change from within a function in that module -- say, a count
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2956 of calls to a function, or an option flag, etc. Until now this was
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2957 not directly possible. While several kludges are known that
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2958 circumvent the problem, and often the need for a global variable can
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2959 be avoided by rewriting the module as a class, this does not always
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2960 lead to clearer code.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2961
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2962 The 'global' statement solves this dilemma. Its occurrence in a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2963 function body means that, for the duration of that function, the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2964 names listed there refer to global variables. For instance:
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2965
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2966 total = 0.0
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2967 count = 0
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2968
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2969 def add_to_total(amount):
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2970 global total, count
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2971 total = total + amount
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2972 count = count + 1
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2973
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2974 'global' must be repeated in each function where it is needed. The
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2975 names listed in a 'global' statement must not be used in the function
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2976 before the statement is reached.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2977
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2978 Remember that you don't need to use 'global' if you only want to use
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2979 a global variable in a function; nor do you need ot for assignments to
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2980 parts of global variables (e.g., list or dictionary items or
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2981 attributes of class instances). This has not changed; in fact
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2982 assignment to part of a global variable was the standard workaround.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2983
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2984
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2985 New exceptions
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2986 --------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2987
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2988 Several new exceptions have been defined, to distinguish more clearly
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	2989 between different types of errors.

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3003 The string value of each exception is now its name -- this makes it
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3004 easier to experimentally find out which operations raise which
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3005 exceptions; e.g.:

c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3013 ------------------------------
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3014
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3015 Off-line discussions with Steve Majewski and Daniel LaLiberte have
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3016 convinced me that Python's parameter mechanism could be changed in a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3017 way that made both of them happy (I hope), kept me happy, fixed a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3018 number of outstanding problems, and, given some backward compatibility
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3019 provisions, would only break a very small amount of existing code --
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3020 probably all mine anyway. In fact I suspect that most Python users
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3021 will hardly notice the difference. And yet it has cost me at least
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3022 one sleepless night to decide to make the change...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3023
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3024 Philosophically, the change is quite radical (to me, anyway): a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3025 function is no longer called with either zero or one argument, which
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3026 is a tuple if there appear to be more arguments. Every function now
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3027 has an argument list containing 0, 1 or more arguments. This list is
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3028 always implemented as a tuple, and it is a (run-time) error if a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3029 function is called with a different number of arguments than expected.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3030
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3031 What's the difference? you may ask. The answer is, very little unless
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3032 you want to write variadic functions -- functions that may be called
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3033 with a variable number of arguments. Formerly, you could write a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3034 function that accepted one or more arguments with little trouble, but
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3035 writing a function that could be called with either 0 or 1 argument
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3036 (or more) was next to impossible. This is now a piece of cake: you
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3037 can simply declare an argument that receives the entire argument
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3038 tuple, and check its length -- it will be of size 0 if there are no
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3039 arguments.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3040
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3041 Another anomaly of the old system was the way multi-argument methods
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3042 (in classes) had to be declared, e.g.:
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3043
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3044 class Point():
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3045 def init(self, (x, y, color)): ...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3046 def setcolor(self, color): ...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3047 dev moveto(self, (x, y)): ...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3048 def draw(self): ...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3049
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3050 Using the new scheme there is no need to enclose the method arguments
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3051 in an extra set of parentheses, so the above class could become:
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3052
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3053 class Point:
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3054 def init(self, x, y, color): ...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3055 def setcolor(self, color): ...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3056 dev moveto(self, x, y): ...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3057 def draw(self): ...
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3058
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3059 That is, the equivalence rule between methods and functions has
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3060 changed so that now p.moveto(x,y) is equivalent to Point.moveto(p,x,y)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3061 while formerly it was equivalent to Point.moveto(p,(x,y)).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3062
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3063 A special backward compatibility rule makes that the old version also
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3064 still works: whenever a function with exactly two arguments (at the top
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3065 level) is called with more than two arguments, the second and further
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3066 arguments are packed into a tuple and passed as the second argument.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3067 This rule is invoked independently of whether the function is actually a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3068 method, so there is a slight chance that some erroneous calls of
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3069 functions expecting two arguments with more than that number of
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3070 arguments go undetected at first -- when the function tries to use the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3071 second argument it may find it is a tuple instead of what was expected.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3072 Note that this rule will be removed from future versions of the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3073 language; it is a backward compatibility provision only.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3074
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3075 Two other rules and a new built-in function handle conversion between
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3076 tuples and argument lists:
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3077
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3078 Rule (a): when a function with more than one argument is called with a
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3079 single argument that is a tuple of the right size, the tuple's items
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3080 are used as arguments.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3081
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3082 Rule (b): when a function with exactly one argument receives no
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3083 arguments or more than one, that one argument will receive a tuple
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3084 containing the arguments (the tuple will be empty if there were no
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3085 arguments).
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3086
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3087
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3088 A new built-in function, apply(), was added to support functions that
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3089 need to call other functions with a constructed argument list. The call
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3090
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3091 apply(function, tuple)
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3092
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3093 is equivalent to
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3094
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3095 function(tuple[0], tuple[1], ..., tuple[len(tuple)-1])
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3096
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3097
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3098 While no new argument syntax was added in this phase, it would now be
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3099 quite sensible to add explicit syntax to Python for default argument
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3100 values (as in C++ or Modula-3), or a "rest" argument to receive the
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3101 remaining arguments of a variable-length argument list.
c9b3f77e18ba Initial revision Guido van Rossum <guido@python.org> parents: diff changeset	3102
