| | | | _active shouldn't be cached, it set to None on shutdown.
* Fixes issue #19929: Call os.read with 32768 within subprocess.PopenGregory P. Smith2013-12-081-1/+1
| | | | | communicate rather than 4096 for efficiency. A microbenchmark shows Linux and OS X both using ~50% less cpu time this way.
* Fixes issue #19506: Use a memoryview to avoid a data copy when piping dataGregory P. Smith2013-12-081-2/+5

* Cleanup of documentation change from #17860Ronald Oussoren2013-07-071-0/+3

* Prevent a possible double close of parent pipe fds when the subprocessGregory P. Smith2013-06-161-18/+25

|\ | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | misleading error message stating that args[0] did not exist when either the cwd or executable keyword arguments specified a path that did not exist. It now keeps track of if the child got as far as preexec and reports it if not back to the parent via a special "noexec" error message value in the error pipe so that the cwd can be blamed for a failed chdir instead of the exec of the executable being blamed instead. The executable is also always reported accurately when exec fails. Unittests enhanced to cover these cases.
