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.

f41406409e - Issue #2113: Fix error in subprocess.Popen if the select system call is 
interrupted by a signal.

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.

Candidate for backport to release25-maint.

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).

subprocess creation in close_fds mode. Patch by Mike Klaas.

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

var == None and var != None
with
var is None and var is not None

and type(var) == int
with
instanceof(var, int)
