This slows the test down, but should make it correct. There was a race condition before where the server could have assigned a port, yet it wasn't ready to serve requests. If the client sent a request before the server was completely ready, it would get an exception. There was machinery to try to handle this condition. All of that should be unnecessary and removed if this change works. A NOTE was added as a comment about what needs to be fixed. The buildbots will tell us if there are more errors or if this test is now stable. ........ r60307 | neal.norwitz | 2008-01-26 08:38:03 +0100 (Sat, 26 Jan 2008) | 3 lines Fix exception in tearDown on ppc buildbot. If there's no directory, that shouldn't cause the test to fail. Just like it setUp. ........ r60308 | raymond.hettinger | 2008-01-26 09:19:06 +0100 (Sat, 26 Jan 2008) | 3 lines Make PySet_Add() work with frozensets. Works like PyTuple_SetItem() to build-up values in a brand new frozenset. ........ r60309 | neal.norwitz | 2008-01-26 09:26:00 +0100 (Sat, 26 Jan 2008) | 1 line The OS X buildbot had errors with the unavailable exceptions disabled. Restore it. ........ r60310 | raymond.hettinger | 2008-01-26 09:37:28 +0100 (Sat, 26 Jan 2008) | 4 lines Let marshal build-up sets and frozensets one element at a time. Saves the unnecessary creation of a tuple as intermediate container. ........ r60311 | raymond.hettinger | 2008-01-26 09:41:13 +0100 (Sat, 26 Jan 2008) | 1 line Update test code for change to PySet_Add(). ........ r60312 | raymond.hettinger | 2008-01-26 10:31:11 +0100 (Sat, 26 Jan 2008) | 1 line Revert PySet_Add() changes. ........ r60314 | georg.brandl | 2008-01-26 10:43:35 +0100 (Sat, 26 Jan 2008) | 2 lines #1934: fix os.path.isabs docs. ........ r60316 | georg.brandl | 2008-01-26 12:00:18 +0100 (Sat, 26 Jan 2008) | 2 lines Add missing things in re docstring. ........ r60317 | georg.brandl | 2008-01-26 12:02:22 +0100 (Sat, 26 Jan 2008) | 2 lines Slashes allowed on Windows. ........ r60319 | georg.brandl | 2008-01-26 14:41:21 +0100 (Sat, 26 Jan 2008) | 2 lines Fix markup again. ........ r60320 | andrew.kuchling | 2008-01-26 14:50:51 +0100 (Sat, 26 Jan 2008) | 1 line Add some items ........ r60321 | georg.brandl | 2008-01-26 15:02:38 +0100 (Sat, 26 Jan 2008) | 2 lines Clarify "b" mode under Unix. ........ r60322 | georg.brandl | 2008-01-26 15:03:47 +0100 (Sat, 26 Jan 2008) | 3 lines #1940: make it possible to use curses.filter() before curses.initscr() as the documentation says. ........ r60324 | georg.brandl | 2008-01-26 15:14:20 +0100 (Sat, 26 Jan 2008) | 3 lines #1473257: add generator.gi_code attribute that refers to the original code object backing the generator.

Will backport. ........ r60335 | neal.norwitz | 2008-01-27 00:14:17 +0100 (Sun, 27 Jan 2008) | 2 lines Consistently use tempfile.tempdir for the db_home directory. ........ r60338 | neal.norwitz | 2008-01-27 02:44:05 +0100 (Sun, 27 Jan 2008) | 4 lines Eliminate the sleeps that assume the server will start in .5 seconds. This should make the test less flaky. It also speeds up the test by about 75% on my box (20+ seconds -> ~4 seconds). ........ r60342 | neal.norwitz | 2008-01-27 06:02:34 +0100 (Sun, 27 Jan 2008) | 6 lines Try to prevent this test from being flaky. We might need a sleep in here which isn't as bad as it sounds. The close() *should* raise an exception, so if it didn't we should give more time to sync and really raise it. Will backport. ........ r60344 | jeffrey.yasskin | 2008-01-27 06:40:35 +0100 (Sun, 27 Jan 2008) | 3 lines Make rational.gcd() public and allow Rational to take decimal strings, per Raymond's advice. ........ r60345 | neal.norwitz | 2008-01-27 08:36:03 +0100 (Sun, 27 Jan 2008) | 3 lines Mostly reformat. Also set an error and return NULL if neither MS_WINDOWS nor UNIX is defined. This may have caused problems on cygwin. ........ r60346 | neal.norwitz | 2008-01-27 08:37:38 +0100 (Sun, 27 Jan 2008) | 3 lines Use int for the sign rather than a char. char can be signed or unsigned. It's system dependent. This might fix the problem with test_rfind failing. ........ r60347 | neal.norwitz | 2008-01-27 08:41:33 +0100 (Sun, 27 Jan 2008) | 1 line Add stdarg include for va_list to get this to compile on cygwin ........ r60348 | raymond.hettinger | 2008-01-27 11:13:57 +0100 (Sun, 27 Jan 2008) | 1 line Docstring nit ........ r60349 | raymond.hettinger | 2008-01-27 11:47:55 +0100 (Sun, 27 Jan 2008) | 1 line Removed an unnecessary and confusing paragraph from the namedtuple docs. ........

-``'b'`` appended to the mode opens the file in binary mode, so there are
-also modes like ``'rb'``, ``'wb'``, and ``'r+b'``. Python distinguishes
-between text and binary files. Binary files are read and written without
-any data transformation. In text mode, platform-specific newline
-representations are automatically converted to newlines when read and
-newline characters are automatically converted to the proper

-code which reads or writes text files easier. In addition, when reading

+On Windows and the Macintosh, ``'b'`` appended to the mode opens the file in

+Windows makes a distinction between text and binary files; the end-of-line

+text files, but it'll corrupt binary data like that in :file:`JPEG` or
+:file:`EXE` files. Be very careful to use binary mode when reading and writing
+such files. On Unix, it doesn't hurt to append a ``'b'`` to the mode, so
+you can use it platform-independently for all binary files.
