Brett Cannon 417439e6cd Partially revert the over-reaching r80813. 2010-05-05 20:24:30 +00:00
Brett Cannon 0b03f10afb Remove three unneeded variable assignments.
Found using Clang's static analyzer.

Mark Dickinson ef9b4abfea Fix trailing whitespace. 2010-05-04 16:19:06 +00:00
Mark Dickinson a8d2668818 Issue #1533: fix inconsistency in range function argument processing:
any non-float non-integer argument is now converted to an integer (if
possible) using its __int__ method.  Previously, only small arguments
were treated this way; larger arguments (those whose __int__ was
outside the range of a C long) would produce a TypeError.

Patch by Alexander Belopolsky (with minor modifications).

Brett Cannon 1994969c15 When DeprecationWarning was silenced by default, it also silenced any use of -Q
by default as well. This change fixes that by treating -Q like -3 when it comes
to DeprecationWarning; using it causes the silencing to not occur.

Fixes issue #7319.

[svn r6499] Support for keyword arguments (PyArg_ParseTupleAndKeywords) donated by
Geoff Philbrick <philbric@delphi.hks.com> (slightly changed by me).

Also a little change to make the file acceptable to K&R C compilers
(HPUX, SunOS 4.x).

Benjamin Peterson 565d78586b normalize exceptions passed to the __exit__ method #7853
In Python 2.x, exceptions in finally blocks are not normalized.  Since with

distinguish between with finally blocks and normal ones.

A test for the finalization of generators containing with statements was also
added.

Brett Cannon 3ffa43db48 The silencing of DeprecationWarning was not taking -3 into consideration. Since
Py3K warnings are DeprecationWarning by default this was causing -3 to
essentially be a no-op. Now DeprecationWarning is only silenced if -3 is not
used.

Brett Cannon 6fdd3dcb6a DeprecationWarning is now silent by default.
This was originally suggested by Guido, discussed on the stdlib-sig mailing
list, and given the OK by Guido directly to me. What this change essentially
means is that Python has taken a policy of silencing warnings that are only
of interest to developers by default. This should prevent users from seeing
warnings which are triggered by an application being run against a new
interpreter before the app developer has a chance to update their code.

Closes issue #7319. Thanks to Antoine Pitrou, Ezio Melotti, and Brian Curtin
for helping with the issue.

2009-09-29 19:01:06 +00:00
Thomas Wouters c4dcb3801e Fix issue #1590864, multiple threads and fork() can cause deadlocks, by
acquiring the import lock around fork() calls. This prevents other threads
from having that lock while the fork happens, and is the recommended way of
dealing with such issues. There are two other locks we care about, the GIL
and the Thread Local Storage lock. The GIL is obviously held when calling
Python functions like os.fork(), and the TLS lock is explicitly reallocated
instead, while also deleting now-orphaned TLS data.

This only fixes calls to os.fork(), not extension modules or embedding
programs calling C's fork() directly. Solving that requires a new set of API
functions, and possibly a rewrite of the Python/thread_*.c mess. Add a
warning explaining the problem to the documentation in the mean time.

This also changes behaviour a little on AIX. Before, AIX (but only AIX) was
getting the import lock reallocated, seemingly to avoid this very same
problem. This is not the right approach, because the import lock is a
re-entrant one, and reallocating would do the wrong thing when forking while
holding the import lock.

Will backport to 2.6, minus the tiny AIX behaviour change.
