* [3.6] bpo-31250: test_asyncio: fix dangling threads (#3517)Victor Stinner2017-09-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | * bpo-31250, test_asyncio: fix dangling threads (#3252) * Explicitly call shutdown(wait=True) on executors to wait until all threads complete to prevent side effects between tests. * Fix test_loop_self_reading_exception(): don't mock loop.close(). Previously, the original close() method was called rather than the mock, because how set_event_loop() registered loop.close(). (cherry picked from commit 16432beadb8eba079c9786cc0c0eaacfd9fd2f7b) * bpo-31250, test_asyncio: fix EventLoopTestsMixin.tearDown() (#3264) Call doCleanups() to close the loop after calling executor.shutdown(wait=True): see TestCase.set_event_loop() of asyncio.test_utils. Replace also gc.collect() with support.gc_collect(). (cherry picked from commit e8a533fbc734af6eeb389202ba6c6e9c2548027f)

| | | | | | | | | | * bpo-31034: Reliable signal handler for test_asyncio Don't rely on the current SIGHUP signal handler, make sure that it's set to the "default" signal handler: SIG_DFL. * Add comments (cherry picked from commit 830080913c22a9834d310294b9f7653234dc6a59)

* asyncio: Skip getaddrinfo if host is already resolved.Yury Selivanov2015-12-171-4/+0
| | | | | | | | | | | | | getaddrinfo takes an exclusive lock on some platforms, causing clients to queue up waiting for the lock if many names are being resolved concurrently. Users may want to handle name resolution in their own code, for the sake of caching, using an alternate resolver, or to measure DNS duration separately from connection duration. Skip getaddrinfo if the "host" passed into create_connection is already resolved. See https://github.com/python/asyncio/pull/302 for details. Patch by A. Jesse Jiryu Davis.

* Issue #25114, asyncio: add ssl_object extra info to SSL transportsVictor Stinner2015-09-211-12/+63
| | | | | | This info is required on Python 3.5 and newer to get specific information on the SSL object, like getting the binary peer certificate (instead of getting it as text).
* asyncio: Only call _check_resolved_address() in debug modeVictor Stinner2015-02-041-0/+4
| | | | | | | | | | | | | | | | * _check_resolved_address() is implemented with getaddrinfo() which is slow * If available, use socket.inet_pton() instead of socket.getaddrinfo(), because it is much faster Microbenchmark (timeit) on Fedora 21 (Python 3.4, Linux 3.17, glibc 2.20) to validate the IPV4 address "127.0.0.1" or the IPv6 address "::1": * getaddrinfo() 10.4 usec per loop * inet_pton(): 0.285 usec per loop On glibc older than 2.14, getaddrinfo() always requests the list of all local IP addresses to the kernel (using a NETLINK socket). getaddrinfo() has other known issues, it's better to avoid it when it is possible.
* asyncio: sync with TulipVictor Stinner2015-01-291-17/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | * 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.
* Issue #22560: New SSL implementation based on ssl.MemoryBIOVictor Stinner2015-01-131-10/+48
| | | | | | | | | | | | | | | | | | | The new SSL implementation is based on the new ssl.MemoryBIO which is only available on Python 3.5. On Python 3.4 and older, the legacy SSL implementation (using SSL_write, SSL_read, etc.) is used. The proactor event loop only supports the new implementation. The new asyncio.sslproto module adds _SSLPipe, SSLProtocol and _SSLProtocolTransport classes. _SSLPipe allows to "wrap" or "unwrap" a socket (switch between cleartext and SSL/TLS). Patch written by Antoine Pitrou. sslproto.py is based on gruvi/ssl.py of the gruvi project written by Geert Jansen. This change adds SSL support to ProactorEventLoop on Python 3.5 and newer! It becomes also possible to implement STARTTTLS: switch a cleartext socket to SSL.

Overlapped operations also work on blocking sockets. * Fix unit tests in debug mode: mock a non-blocking socket for socket operations which now raise an exception if the socket is blocking. * _fatal_error() method of _UnixReadPipeTransport and _UnixWritePipeTransport now log all exceptions in debug mode * Don't log expected errors in unit tests * Tulip issue 200: _WaitHandleFuture._unregister_wait() now catchs and logs exceptions. * Tulip issue 200: Log errors in debug mode instead of simply ignoring them.
