Merged revisions 53952-54987 via svnmerge from svn+ssh://pythondev@svn.python.org/python/trunk ........ r53954 | jeremy.hylton | 2007-02-26 10:41:18 -0800 (Mon, 26 Feb 2007) | 10 lines Do not copy free variables to locals in class namespaces. Fixes bug 1569356, but at the cost of a minor incompatibility in locals(). Add test that verifies that the class namespace is not polluted. Also clarify the behavior in the library docs. Along the way, cleaned up the dict_to_map and map_to_dict implementations and added some comments that explain what they do. ........ r53955 | jeremy.hylton | 2007-02-26 11:00:20 -0800 (Mon, 26 Feb 2007) | 2 lines Fix assertion. ........ r53969 | neal.norwitz | 2007-02-26 14:41:45 -0800 (Mon, 26 Feb 2007) | 3 lines When printing an unraisable error, don't print exceptions. before the name.

We add some new rules that are required for preserving internal invariants of types. 1. If type (or a subclass of type) appears in bases, it must appear before any non-type bases. If a non-type base (like a regular new-style class) occurred first, it could trick type into allocating the new class an __dict__ which must be impossible. 2. There are several checks that are made of bases when creating a type. Those checks are now repeated when assigning to __bases__. We also add the restriction that assignment to __bases__ may not change the metaclass of the type. Add new tests for these cases and for a few other oddball errors that were no previously tested. Remove a crasher test that was fixed. Also some internal refactoring: Extract the code to find the most derived metaclass of a type and its bases. It is now needed in two places. Rewrite the TypeError checks in test_descr to use doctest. The tests now clearly show what exception they expect to see. ........ r53998 | jeremy.hylton | 2007-02-27 10:33:31 -0800 (Tue, 27 Feb 2007) | 2 lines Add news about changes to metaclasses and __bases__ error checking. ........ r54016 | armin.rigo | 2007-02-28 01:25:29 -0800 (Wed, 28 Feb 2007) | 3 lines Modify the segfaulting example to show why r53997 is not a solution to it. ........ r54022 | brett.cannon | 2007-02-28 10:15:00 -0800 (Wed, 28 Feb 2007) | 2 lines Add a test for instantiating SyntaxError with no arguments. ........ r54026 | raymond.hettinger | 2007-02-28 10:27:41 -0800 (Wed, 28 Feb 2007) | 1 line Docstring nit. ........ r54033 | raymond.hettinger | 2007-02-28 10:37:52 -0800 (Wed, 28 Feb 2007) | 1 line Prepare collections module for pure python code entries. ........ r54053 | raymond.hettinger | 2007-02-28 22:16:43 -0800 (Wed, 28 Feb 2007) | 1 line Add collections.NamedTuple ........ r54054 | neal.norwitz | 2007-02-28 23:04:41 -0800 (Wed, 28 Feb 2007) | 1 line Add Pat and Eric for work on PEP 3101 in the sandbox ........ r54061 | andrew.kuchling | 2007-03-01 06:36:12 -0800 (Thu, 01 Mar 2007) | 1 line Add NamedTuple ........ r54080 | georg.brandl | 2007-03-02 06:37:12 -0800 (Fri, 02 Mar 2007) | 2 lines Bug #1628895: some better tries to find HTML documentation in pydoc. ........ r54086 | raymond.hettinger | 2007-03-02 11:20:46 -0800 (Fri, 02 Mar 2007) | 1 line Fix embarrassing typo and fix constantification of None ........ r54088 | georg.brandl | 2007-03-02 12:30:14 -0800 (Fri, 02 Mar 2007) | 2 lines Bugs #1668032, #1668036, #1669304: clarify behavior of PyMem_Realloc and _Resize. ........ r54114 | georg.brandl | 2007-03-04 09:18:54 -0800 (Sun, 04 Mar 2007) | 2 lines Fix a bug in test_dict and test_userdict, found at the PyPy sprint. ........ r54124 | skip.montanaro | 2007-03-04 12:52:28 -0800 (Sun, 04 Mar 2007) | 2 lines Teach setup.py how to find Berkeley DB on Macs using MacPorts. ........ r54125 | skip.montanaro | 2007-03-04 12:54:12 -0800 (Sun, 04 Mar 2007) | 1 line note MacPorts/BerkDB change in setup.py ........ r54136 | neal.norwitz | 2007-03-04 23:52:01 -0800 (Sun, 04 Mar 2007) | 1 line Added Pete for 3101 too ........ r54138 | facundo.batista | 2007-03-05 08:31:54 -0800 (Mon, 05 Mar 2007) | 1 line Minor corrections to docs, and an explanation comentary ........ r54139 | georg.brandl | 2007-03-05 14:28:08 -0800 (Mon, 05 Mar 2007) | 3 lines Patch #1674228: when assigning a slice (old-style), check for the sq_ass_slice instead of the sq_slice slot. ........ r54149 | georg.brandl | 2007-03-06 01:33:01 -0800 (Tue, 06 Mar 2007) | 3 lines Nit: a struct field is set to GenericAlloc, not GenericAlloc(). ........ r54150 | georg.brandl | 2007-03-06 02:02:47 -0800 (Tue, 06 Mar 2007) | 3 lines Patch #1671450: add a section about subclassing builtin types to the "extending and embedding" tutorial. ........ r54152 | martin.v.loewis | 2007-03-06 02:41:24 -0800 (Tue, 06 Mar 2007) | 2 lines Patch #1121142: Implement ZipFile.open. ........ r54154 | georg.brandl | 2007-03-06 03:51:14 -0800 (Tue, 06 Mar 2007) | 2 lines A test case for the fix in #1674228. ........ r54156 | georg.brandl | 2007-03-06 03:52:24 -0800 (Tue, 06 Mar 2007) | 2 lines Patch #1672481: fix bug in idlelib.MultiCall. ........ r54159 | georg.brandl | 2007-03-06 04:17:50 -0800 (Tue, 06 Mar 2007) | 1 line Bug #1674503: close the file opened by execfile() in an error condition. ........ r54160 | georg.brandl | 2007-03-06 05:32:52 -0800 (Tue, 06 Mar 2007) | 3 lines Fix another reincarnation of bug #1576657 in defaultdict. ........ r54162 | georg.brandl | 2007-03-06 05:35:00 -0800 (Tue, 06 Mar 2007) | 2 lines A test case for the defaultdict KeyError bug. ........ r54164 | georg.brandl | 2007-03-06 05:37:45 -0800 (Tue, 06 Mar 2007) | 3 lines Patch #1663234: you can now run doctest on test files and modules using "python -m doctest [-v] filename ...". ........ r54165 | martin.v.loewis | 2007-03-06 06:43:00 -0800 (Tue, 06 Mar 2007) | 3 lines Patch #912410: Replace HTML entity references for attribute values in HTMLParser. ........ r54166 | skip.montanaro | 2007-03-06 07:41:38 -0800 (Tue, 06 Mar 2007) | 1 line patch 1673619 - identify extension modules which cannot be built ........ r54167 | guido.van.rossum | 2007-03-06 07:50:01 -0800 (Tue, 06 Mar 2007) | 5 lines Patch #1646728: datetime.fromtimestamp fails with negative fractional times.

The TarInfo class now contains all necessary logic to process and create tar header data which has been moved there from the TarFile class. The fromtarfile() method was added. The new path and linkpath properties are aliases for the name and linkname attributes in correspondence to the pax naming scheme. The TarFile constructor and classmethods now accept a number of keyword arguments which could only be set as attributes before (e.g. dereference, ignore_zeros). The encoding and pax_headers arguments were added for pax support. There is a new tarinfo keyword argument that allows using subclassed TarInfo objects in TarFile. The boolean TarFile.posix attribute is deprecated, because now three tar formats are supported. Instead, the desired format for writing is specified using the constants USTAR_FORMAT, GNU_FORMAT and PAX_FORMAT as the format keyword argument. This change affects TarInfo.tobuf() as well. The test suite has been heavily reorganized and partially rewritten. A new testtar.tar was added that contains sample data in many formats from 4 different tar programs. Some bugs and quirks that also have been fixed: Directory names do no longer have a trailing slash in TarInfo.name or TarFile.getnames(). Adding the same file twice does not create a hardlink file member. The TarFile constructor does no longer need a name argument. The TarFile._mode attribute was renamed to mode and contains either 'r', 'w' or 'a'. ........ r54336 | georg.brandl | 2007-03-13 05:34:25 -0700 (Tue, 13 Mar 2007) | 3 lines Bug #1622896: fix a rare corner case where the bz2 module raised an error in spite of a succesful compression. ........ r54338 | lars.gustaebel | 2007-03-13 08:47:07 -0700 (Tue, 13 Mar 2007) | 3 lines Quick fix for tests that fail on systems with an encoding other than 'iso8859-1'. ........ r54339 | georg.brandl | 2007-03-13 10:43:32 -0700 (Tue, 13 Mar 2007) | 4 lines Patch #1603688: ConfigParser.SafeConfigParser now checks values that are set for invalid interpolation sequences that would lead to errors on reading back those values. ........ r54341 | georg.brandl | 2007-03-13 11:15:41 -0700 (Tue, 13 Mar 2007) | 3 lines Patch #1581073: add a flag to textwrap that prevents the dropping of whitespace while wrapping. ........ r54343 | georg.brandl | 2007-03-13 11:24:40 -0700 (Tue, 13 Mar 2007) | 2 lines Patch #1605192: list allowed states in error messages for imaplib. ........ r54344 | georg.brandl | 2007-03-13 11:31:49 -0700 (Tue, 13 Mar 2007) | 4 lines Patch #1537850: tempfile.NamedTemporaryFile now has a "delete" parameter which can be set to False to prevent the default delete-on-close behavior. ........ r54345 | collin.winter | 2007-03-13 11:53:04 -0700 (Tue, 13 Mar 2007) | 9 lines Add acks for recent patch checkins: Arvin Schnell - 1668482 S?\195?\169bastien Martini - 1481079 Heiko Wundram - 1491866 Damon Kohler - 1545011 Peter Parente - 1599845 Bjorn Lindqvist - 1678662 ........ r54346 | georg.brandl | 2007-03-13 12:00:36 -0700 (Tue, 13 Mar 2007) | 2 lines Acks for recent patches. ........ r54347 | georg.brandl | 2007-03-13 12:18:18 -0700 (Tue, 13 Mar 2007) | 3 lines Fix a tab. ........ r54348 | georg.brandl | 2007-03-13 12:32:21 -0700 (Tue, 13 Mar 2007) | 4 lines Patch #1533909: the timeit module now accepts callables in addition to strings for the code to time and the setup code.
