d5c8ce7cc0 Issue #19612: On Windows, subprocess.Popen.communicate() now ignores
OSError(22, 'Invalid argument') when writing input data into stdin, whereas
the process already exited.

72e7761301 issue12085: Use more Pythonic way to check _child_created.
_active shouldn't be cached, it set to None on shutdown.

589ecda56e Fixes issue #19929: Call os.read with 32768 within subprocess.Popen
communicate rather than 4096 for efficiency.  A microbenchmark shows
Linux and OS X both using ~50% less cpu time this way.

774f909489 Fixes issue #19506: Use a memoryview to avoid a data copy when piping data
to stdin within subprocess.Popen.communicate.  5-10% less cpu usage.

361e30c17a Undo supposed fix for Issue #15798 until I understand why this is
causing test_multiprocessing_forkserver and test_multiprocessing_spawn
failures on head (3.4).

Reformulated the textual change, and applied it to the docstring as well.

b5461b9884 Prevent a possible double close of parent pipe fds when the subprocess
exec runs into an error.  Prevent a regular multi-close of the /dev/null
fd when any of stdin, stdout and stderr was set to DEVNULL.

a1b9ed32ee Fixes issue #17488: Change the subprocess.Popen bufsize parameter default value
from unbuffered (0) to buffering (-1) to match the behavior existing code
expects and match the behavior of the subprocess module in Python 2 to avoid
introducing hard to track down bugs.

available when configured at compile time.

91110f5e55 Use a larger amount of data for tests such as the interrupted_write
tests that depend on filling up an OS pipe so that they work properly
on systems configured with large pipe buffers.

c8ac03d936 Fixes issue #16140: The subprocess module no longer double closes its
child subprocess.PIPE parent file descriptors on child error prior to
exec().

This would lead to race conditions in multithreaded programs where
another thread opened a file reusing the fd which was then closed out
from beneath it by the errant second close.

6893732c35 Remove the subprocess "bad exception data" warning (formerly a print!)
all together and just include the repr of the data in the exception
itself instead of the useless string "Unknown".

This code path is unlikely to even be possible to take given the
nature of the pipe it gets subprocess data from.

1f83866ecd Rename a local variable for readability and change a "this can't
happen" print() call into a RuntimeWarning as it should've been in the
first place.  Because nothing should ever cause unexpected stdout output.
