5e8dc97a09 Backport of r65032 from trunk 
Fixes Issue #874900: after an os.fork() call the threading module state is cleaned
up in the child process to prevent deadlock and report proper thread counts
if the new process uses the threading module.

bc212104e4 No need to emit co_lnotab item when both offsets are zeros. 
r60579 broke a test test_compile, which seems to test an "implementation detail" IMO.

Also test that this correction does not impact the debugger.

316f8a8d3c backport of r60575 (issue #1750076): Debugger did not step on every iteration of a while statement. 
The mapping between bytecode offsets and source lines (lnotab) did not contain
an entry for the beginning of the loop.

Now it does, and the lnotab can be a bit larger:
in particular, several statements on the same line generate several entries.
However, this does not bother the settrace function, which will trigger only
one 'line' event.

The lnotab seems to be exactly the same as with python2.4.

f1a7178cd5 #1920: when considering a block starting by "while 0", the compiler optimized the 
whole construct away, even when an 'else' clause is present::

    while 0:
        print("no")
    else:
        print("yes")

did not generate any code at all.

Now the compiler emits the 'else' block, like it already does for 'if' statements.

Backport of r60265.

c572dc3752 Backport for issue1265 (pdb bug with "with" statement). 
When an unfinished generator-iterator is garbage collected, PyEval_EvalFrameEx
is called with a GeneratorExit exception set.  This leads to funny results
if the sys.settrace function itself makes use of generators.
A visible effect is that the settrace function is reset to None.
Another is that the eventual "finally" block of the generator is not called.

It is necessary to save/restore the exception around the call to the trace
function.

This happens a lot with py3k: isinstance() of an ABCMeta instance runs
    def __instancecheck__(cls, instance):
        """Override for isinstance(instance, cls)."""
        return any(cls.__subclasscheck__(c)
                   for c in {instance.__class__, type(instance)})
which lets an opened generator expression each time it returns True.

And the problem can be reproduced in 2.5 with pure python code.

b4c285a25b Fix NonRecursiveMutex on x64. The signature of the faux-InterlockedCompareExchange function was wrong: It works with LONG and not PVOID objects, and it needs to have the target marked as volatile. Further, it is not needed at all for x64 targets, since that platform always has the real McCoy. 2007-05-07 18:28:12 +00:00

e471317a08 Backport trunk revision 53527: 
SF patch #1630975: Fix crash when replacing sys.stdout in sitecustomize

When running the interpreter in an environment that would cause it to set
stdout/stderr/stdin's encoding, having a sitecustomize that would replace
them with something other than PyFile objects would crash the interpreter.
Fix it by simply ignoring the encoding-setting for non-files.

This could do with a test, but I can think of no maintainable and portable
way to test this bug, short of adding a sitecustomize.py to the buildsystem
and have it always run with it (hmmm....)
