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.

ce32eb7406 #6416: Fix compilation of the select module on Windows, as well as test_subprocess: 
PIPE_BUF is not defined on Windows, and probably has no meaning there.

Anyway the subprocess module uses another way to perform non-blocking reads (with a thread)

dd7ca24eb5 Use select.poll() in subprocess, when available, rather than select() so that 
it does not fail when file descriptors are large.  Fixes issue3392.

Patch largely contributed by Frank Chu (fpmc) with some improvements by me.
See http://bugs.python.org/issue3392.

Candidate for backporting to release26-maint as it is a bug fix and changes no
public API.

03446c43ca Remove warnings generated for the suprocess module when run under -3. Required 
commenting out True/False compatbility stuff, remove a use of apply(), and
remove a use of buffer() (just pulled the solution used in 3.0 which is direct
slicing).

a36f8fefb0 - Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword 
argument in python 2.5, this broke code that subclassed Popen to include its
  own poll method.  Fixed my moving _deadstate to an _internal_poll method.

4036fd4b75 Fixes issue2791: subprocess.Popen.communicate leaked a file descripton until 
the last reference to the Popen instance was dropped.  Adding explicit
close() calls fixes it.

e74c8f2879 Added kill, terminate and send_signal to subprocess.Popen 
The bits and pieces for the Windows side were already in place. The POSIX side is trivial (as usual) and uses os.kill().

92ffc634e4 Undo an unnecessary else: and indentation that r60104 added. 
try:
  ...
except:
  ...
  raise
else:

the else: is unecessary due to the blind except: with a raise.

87d49792b5 Fixes issue1336 - a race condition could occur when forking if the gc 
kicked in during the critical section.  solution: disable gc during
that section.  Patch contributed by jpa and updated by me to cover the
race condition still existing what therve from twistedmatrix pointed
out (already seen and fixed in twisted's own subprocess code).

f54000325b We had several if statements checking the value of a fd. This is unsafe, since valid fds might be zero. We should check for not None instead. 2007-02-02 19:06:36 +00:00
