Gregory P. Smith 0d207fd8cf Fixes issue #26083: Workaround a subprocess bug that raised an incorrect
"ValueError: insecure string pickle" exception instead of the actual exception
on some platforms such as Mac OS X when an exception raised in the forked child
process prior to the exec() was large enough that it overflowed the internal
errpipe_read pipe buffer.

  Fix #8956. ValueError message was only mentioning one signal.

  Rather than list out the three signals (or more over time), the message was
  made less specific but still descriptive.

Jean-Paul Calderone b33f0c1ccd Revert r60115
This revision introduced quoting for strings containing | based
on a misunderstanding of the commonly used quoting rules used
on Windows.

| is interpreted by cmd.exe, not by the MS C runtime argv initializer.
It only needs to be quoted if it is part of an argument passed through
cmd.exe.

Victor Stinner 2b271f7e30 Fix regression introduced by r81154 (Issue #5099, subprocess destructor) 2010-05-14 21:52:26 +00:00
Brett Cannon 42a0ba7b2c subprocess.Popen.__del__ referenced global objects, which is a no-no thanks to
interpreter shutdown semantics. Same issue goes for the methods that __del__
called. Now all the methods capture the global objects it needs as default
values to private parameters (could have stuck them on the class object itself,
but since the objects have nothing directly to do with the class that seemed
wrong).

There is no test as making one that works is hard. This patch was
verified against a consistently failing test in Mercurial's test suite, though,
so it has been tested in some regard.

Closes issue #5099. Thanks to Mary Stern for the bug report and Gabriel
Genellina for writing another patch for the same issue and attempting to write
a test.

Brett Cannon 3d6137962c Revert an accidental commit from r80492. 2010-04-25 23:11:51 +00:00
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.

Brian Curtin a2936cfa09 Fix #7838. Add docstrings and privatize _subprocess implementation details.
Since CREATE_NEW_* are used for the creation flags of a subprocess, they
were added to __all__. The rest of the previously exposed attributes are
now qualified by _subprocess.ATTR rather than importing *.

Brian Curtin e5aa886b44 Implement #1220212. Add os.kill support for Windows.
os.kill takes one of two newly added signals, CTRL_C_EVENT and
CTRL_BREAK_EVENT, or any integer value. The events are a special case
which work with subprocess console applications which implement a
special console control handler. Any other value but those two will
cause os.kill to use TerminateProcess, outright killing the process.

This change adds win_console_handler.py, which is a script to implement
SetConsoleCtrlHandler and applicable handler function, using ctypes.

subprocess also gets another attribute which is a necessary flag to
creationflags in Popen in order to send the CTRL events.
