* asyncio: sync with githubVictor Stinner2015-07-251-2/+0
| | | | | | | | | * Fix ResourceWarning warnings in test_streams * Return True from StreamReader.eof_received() to fix http://bugs.python.org/issue24539 (but still needs a unittest). Add StreamReader.__repr__() for easy debugging. * remove unused imports * Issue #234: Drop JoinableQueue on Python 3.5+

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #23347: send_signal(), kill() and terminate() methods of BaseSubprocessTransport now check if the transport was closed and if the process exited. Issue #23347: Refactor creation of subprocess transports. Changes on BaseSubprocessTransport: * Add a wait() method to wait until the child process exit * The constructor now accepts an optional waiter parameter. The _post_init() coroutine must not be called explicitly anymore. It makes subprocess transports closer to other transports, and it gives more freedom if we want later to change completly how subprocess transports are created. * close() now kills the process instead of kindly terminate it: the child process may ignore SIGTERM and continue to run. Call explicitly terminate() and wait() if you want to kindly terminate the child process. * close() now logs a warning in debug mode if the process is still running and needs to be killed * _make_subprocess_transport() is now fully asynchronous again: if the creation of the transport failed, wait asynchronously for the process eixt. Before the wait was synchronous. This change requires close() to *kill*, and not terminate, the child process. * Remove the _kill_wait() method, replaced with a more agressive close() method. It fixes _make_subprocess_transport() on error. BaseSubprocessTransport.close() calls the close() method of pipe transports, whereas _kill_wait() closed directly pipes of the subprocess.Popen object without unregistering file descriptors from the selector (which caused severe bugs). These changes simplifies the code of subprocess.py.

* Python issue #23173: sync with TulipVictor Stinner2015-01-141-3/+13
| | | | | | | | * 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.

* asyncio, tulip issue 190: Process.communicate() must ignore BrokenPipeErrorVictor Stinner2014-07-171-1/+5
| | | | | | | | If you want to handle the BrokenPipeError, you can easily reimplement communicate(). Add also a unit test to ensure that stdin.write() + stdin.drain() raises BrokenPipeError.
* asyncio: sync with TulipVictor Stinner2014-07-141-0/+26
| | | | | | | | | | | | | | | | | | | | * 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)
