* PipeHandle now uses None instead of -1 for a closed handle
* Sort imports in windows_utils.
* Fix test_events on Python older than 3.5. Skip SSL tests on the
ProactorEventLoop if ssl.MemoryIO is missing
* Fix BaseEventLoop._create_connection_transport(). Close the transport if the
creation of the transport (if the waiter) gets an exception.
* _ProactorBasePipeTransport now sets _sock to None when the transport is
closed.
* Fix BaseSubprocessTransport.close(). Ignore pipes for which the protocol is
not set yet (still equal to None).
* TestLoop.close() now calls the close() method of the parent class
(BaseEventLoop).
* Cleanup BaseSelectorEventLoop: create the protocol on a separated line for
readability and ease debugging.
* Fix BaseSubprocessTransport._kill_wait(). Set the _returncode attribute, so
close() doesn't try to terminate the process.
* Tests: explicitly close event loops and transports
* UNIX pipe transports: add closed/closing in repr(). Add "closed" or "closing"
state in the __repr__() method of _UnixReadPipeTransport and
_UnixWritePipeTransport classes.
* If an exception is raised during the creation of a subprocess, kill the
subprocess (close pipes, kill and read the return status). Log an error in
such case.
* Fix SubprocessStreamProtocol.connection_made() to handle cancelled waiter.
Add unit test cancelling subprocess methods.
* Fix a race condition in BaseSubprocessTransport._try_finish().
If the process exited before the _post_init() method was called, scheduling
the call to _call_connection_lost() with call_soon() is wrong:
connection_made() must be called before connection_lost().
Reuse the BaseSubprocessTransport._call() method to schedule the call to
_call_connection_lost() to ensure that connection_made() and
connection_lost() are called in the correct order.
* Add repr(PipeHandle)
* Fix typo
* Tulip issue #184: Log subprocess events in debug mode
- Log stdin, stdout and stderr transports and protocols
- Log process identifier (pid)
- Log connection of pipes
- Log process exit
- Log Process.communicate() tasks: feed stdin, read stdout and stderr
- Add __repr__() method to many classes related to subprocesses
* Add BaseSubprocessTransport._pid attribute. Store the pid so it is still
accessible after the process exited. It's more convinient for debug.
* create_connection(): add the socket in the "connected to" debug log
* Clean up some docstrings and comments. Remove unused unimplemented
_read_from_self().
* Add a new asyncio.subprocess module
* Add new create_subprocess_exec() and create_subprocess_shell() functions
* The new asyncio.subprocess.SubprocessStreamProtocol creates stream readers
for stdout and stderr and a stream writer for stdin.
* The new asyncio.subprocess.Process class offers an API close to the
subprocess.Popen class:
- pid, returncode, stdin, stdout and stderr attributes
- communicate(), wait(), send_signal(), terminate() and kill() methods
* Remove STDIN (0), STDOUT (1) and STDERR (2) constants from base_subprocess
and unix_events, to not be confused with the symbols with the same name of
subprocess and asyncio.subprocess modules
* _ProactorBasePipeTransport.get_write_buffer_size() now counts also the size
of the pending write
* _ProactorBaseWritePipeTransport._loop_writing() may now pause the protocol if
the write buffer size is greater than the high water mark (64 KB by default)
