[GSoC - Alan McIntyre] ........ r56488 | nick.coghlan | 2007-07-22 03:18:07 -0700 (Sun, 22 Jul 2007) | 1 line Add explicit relative import tests for runpy.run_module ........ r56509 | nick.coghlan | 2007-07-23 06:41:45 -0700 (Mon, 23 Jul 2007) | 5 lines Correctly cleanup sys.modules after executing runpy relative import tests Restore Python 2.4 ImportError when attempting to execute a package (as imports cannot be guaranteed to work properly if you try it) ........ r56519 | nick.coghlan | 2007-07-24 06:07:38 -0700 (Tue, 24 Jul 2007) | 1 line Tweak runpy test to do a better job of confirming that sys has been manipulated correctly ........ r56520 | nick.coghlan | 2007-07-24 06:58:28 -0700 (Tue, 24 Jul 2007) | 1 line Fix an incompatibility between the -i and -m command line switches as reported on python-dev by PJE - runpy.run_module now leaves any changes it makes to the sys module intact after the function terminates ........ r56523 | nick.coghlan | 2007-07-24 07:39:23 -0700 (Tue, 24 Jul 2007) | 1 line Try to get rid of spurious failure in test_resource on the Debian buildbots by changing the file size limit before attempting to close the file ........ r56533 | facundo.batista | 2007-07-24 14:20:42 -0700 (Tue, 24 Jul 2007) | 7 lines New tests for basic behavior of smtplib.SMTP and smtpd.DebuggingServer. Change to use global host & port number variables. Modified the 'server' to take a string to send back in order to vary test server responses. Added a test for the reaction of smtplib.SMTP to a non-200 HELO response. [GSoC - Alan McIntyre] ........ r56538 | nick.coghlan | 2007-07-25 05:57:48 -0700 (Wed, 25 Jul 2007) | 1 line More buildbot cleanup - let the OS assign the port for test_urllib2_localnet ........ r56539 | nick.coghlan | 2007-07-25 06:18:58 -0700 (Wed, 25 Jul 2007) | 1 line Add a temporary diagnostic message before a strange failure on the alpha Debian buildbot ........ r56543 | martin.v.loewis | 2007-07-25 09:24:23 -0700 (Wed, 25 Jul 2007) | 2 lines Change location of the package index to pypi.python.org/pypi ........ r56551 | georg.brandl | 2007-07-26 02:36:25 -0700 (Thu, 26 Jul 2007) | 2 lines tabs, newlines and crs are valid XML characters. ........ r56553 | nick.coghlan | 2007-07-26 07:03:00 -0700 (Thu, 26 Jul 2007) | 1 line Add explicit test for a misbehaving math.floor ........ r56561 | mark.hammond | 2007-07-26 21:52:32 -0700 (Thu, 26 Jul 2007) | 3 lines In consultation with Kristjan Jonsson, only define WINVER and _WINNT_WIN32 if (a) we are building Python itself and (b) no one previously defined them ........ r56562 | mark.hammond | 2007-07-26 22:08:54 -0700 (Thu, 26 Jul 2007) | 2 lines Correctly detect AMD64 architecture on VC2003 ........ r56566 | nick.coghlan | 2007-07-27 03:36:30 -0700 (Fri, 27 Jul 2007) | 1 line Make test_math error messages more meaningful for small discrepancies in results ........ r56588 | martin.v.loewis | 2007-07-27 11:28:22 -0700 (Fri, 27 Jul 2007) | 2 lines Bug #978833: Close https sockets by releasing the _ssl object. ........ r56601 | martin.v.loewis | 2007-07-28 00:03:05 -0700 (Sat, 28 Jul 2007) | 3 lines Bug #1704793: Return UTF-16 pair if unicodedata.lookup cannot represent the result in a single character. ........ r56604 | facundo.batista | 2007-07-28 07:21:22 -0700 (Sat, 28 Jul 2007) | 9 lines Moved all of the capture_server socket setup code into the try block so that the event gets set if a failure occurs during server setup (otherwise the test will block forever). Changed to let the OS assign the server port number, and client side of test waits for port number assignment before proceeding. The test data in DispatcherWithSendTests is also sent in multiple send() calls instead of one to make sure this works properly. [GSoC - Alan McIntyre] ........ r56611 | georg.brandl | 2007-07-29 01:26:10 -0700 (Sun, 29 Jul 2007) | 2 lines Clarify PEP 343 description. ........ r56614 | georg.brandl | 2007-07-29 02:11:15 -0700 (Sun, 29 Jul 2007) | 2 lines try-except-finally is new in 2.5. ........ r56617 | facundo.batista | 2007-07-29 07:23:08 -0700 (Sun, 29 Jul 2007) | 9 lines Added tests for asynchat classes simple_producer & fifo, and the find_prefix_at_end function. Check behavior of a string given as a producer. Added tests for behavior of asynchat.async_chat when given int, long, and None terminator arguments. Added usepoll attribute to TestAsynchat to allow running the asynchat tests with poll support chosen whether it's available or not (improves coverage of asyncore code). [GSoC - Alan McIntyre] ........ r56620 | georg.brandl | 2007-07-29 10:38:35 -0700 (Sun, 29 Jul 2007) | 2 lines Bug #1763149: use proper slice syntax in docstring. (backport) ........ r56624 | mark.hammond | 2007-07-29 17:45:29 -0700 (Sun, 29 Jul 2007) | 4 lines Correct use of Py_BUILD_CORE - now make sure it is defined before it is referenced, and also fix definition of _WIN32_WINNT. Resolves patch 1761803. ........ r56632 | facundo.batista | 2007-07-30 20:03:34 -0700 (Mon, 30 Jul 2007) | 8 lines When running asynchat tests on OS X (darwin), the test client now overrides asyncore.dispatcher.handle_expt to do nothing, since select.poll gives a POLLHUP error at the completion of these tests. Added timeout & count arguments to several asyncore.loop calls to avoid the possibility of a test hanging up a build. [GSoC - Alan McIntyre] ........ r56633 | nick.coghlan | 2007-07-31 06:38:01 -0700 (Tue, 31 Jul 2007) | 1 line Eliminate RLock race condition reported in SF bug #1764059 ........ r56636 | martin.v.loewis | 2007-07-31 12:57:56 -0700 (Tue, 31 Jul 2007) | 2 lines Define _BSD_SOURCE, to get access to POSIX extensions on OpenBSD 4.1+. ........ r56653 | facundo.batista | 2007-08-01 16:18:36 -0700 (Wed, 01 Aug 2007) | 9 lines Allow the OS to select a free port for each test server. For DebuggingServerTests, construct SMTP objects with a localhost argument to avoid abysmally long FQDN lookups (not relevant to items under test) on some machines that would cause the test to fail. Moved server setup code in the server function inside the try block to avoid the possibility of setup failure hanging the test. Minor edits to conform to PEP 8. [GSoC - Alan McIntyre] ........ r56681 | matthias.klose | 2007-08-02 14:33:13 -0700 (Thu, 02 Aug 2007) | 2 lines - Allow Emacs 22 for building the documentation in info format. ........ r56689 | neal.norwitz | 2007-08-02 23:46:29 -0700 (Thu, 02 Aug 2007) | 1 line Py_ssize_t is defined regardless of HAVE_LONG_LONG. Will backport ........ r56727 | hyeshik.chang | 2007-08-03 21:10:18 -0700 (Fri, 03 Aug 2007) | 3 lines Fix gb18030 codec's bug that doesn't map two-byte characters on GB18030 extension in encoding. (bug reported by Bjorn Stabell) ........ r56751 | neal.norwitz | 2007-08-04 20:23:31 -0700 (Sat, 04 Aug 2007) | 7 lines Handle errors when generating a warning. The value is always written to the returned pointer if getting it was successful, even if a warning causes an error. (This probably doesn't matter as the caller will probably discard the value.) Will backport. ........ ................
