  Changes 54857 and 54840 broke code and were reverted in Py2.5 just before
  it was released, but that reversion never made it to the Py2.6 head.

  Make 'testall' work again when building in a separate directory.
  test_distutils still fails when doing that.
........
  r60305 | neal.norwitz | 2008-01-26 06:54:48 +0100 (Sat, 26 Jan 2008) | 3 lines

  Prevent this test from failing if there are transient network problems
  by retrying the host for up to 3 times.
........
  r60306 | neal.norwitz | 2008-01-26 08:26:12 +0100 (Sat, 26 Jan 2008) | 12 lines

  Use a condition variable (threading.Event) rather than sleeps and checking a
  global to determine when the server is ready to be used.  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.

  Cleanup the code a bit.  test_rfind is failing on PPC and PPC64 buildbots,
  this might fix the problem.
........
  r60330 | neal.norwitz | 2008-01-26 22:02:45 +0100 (Sat, 26 Jan 2008) | 1 line

  Always try to remove the test file even if close raises an exception
........
  r60331 | neal.norwitz | 2008-01-26 22:21:59 +0100 (Sat, 26 Jan 2008) | 3 lines

  Reduce the race condition by signalling when the server is ready
  and not trying to connect before.
........
  r60334 | neal.norwitz | 2008-01-27 00:13:46 +0100 (Sun, 27 Jan 2008) | 5 lines

  On some systems (e.g., Ubuntu on hppa) the flush()
  doesn't cause the exception, but the close() does.

  Will backport.
........
  r60335 | neal.norwitz | 2008-01-27 00:14:17 +0100 (Sun, 27 Jan 2008) | 2 lines

........
  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
