* asyncio: sync with TulipVictor Stinner2014-08-251-6/+25
| | | | | | | | | | | | | | | | | | | | | | | * PipeServer.close() now cancels the "accept pipe" future which cancels the overlapped operation. * Fix _SelectorTransport.__repr__() if the transport was closed * Fix debug log in BaseEventLoop.create_connection(): get the socket object from the transport because SSL transport closes the old socket and creates a new SSL socket object. Remove also the _SelectorSslTransport._rawsock attribute: it contained the closed socket (not very useful) and it was not used. * Issue #22063: socket operations (sock_recv, sock_sendall, sock_connect, sock_accept) of the proactor event loop don't raise an exception in debug mode if the socket are in blocking mode. 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.

| | | | | | | | | | | | | | | | | | | | | | | | * _WaitHandleFuture.cancel() now notify IocpProactor through the overlapped object that the wait was cancelled. * Optimize IocpProactor.wait_for_handle() gets the result if the wait is signaled immediatly. * Enhance representation of Future and Future subclasses - Add "created at filename:lineno" in the representation - Add Future._repr_info() method which can be more easily overriden than Future.__repr__(). It should now be more easy to enhance Future representation without having to modify each subclass. For example, _OverlappedFuture and _WaitHandleFuture get the new "created at" information. - Use reprlib to format Future result, and function arguments when formatting a callback, to limit the length of the representation. * Fix repr(_WaitHandleFuture) * _WaitHandleFuture and _OverlappedFuture: hide frames of internal calls in the source traceback. * Cleanup ProactorIocp._poll(): set the timeout to 0 after the first call to GetQueuedCompletionStatus() * test_locks: close the temporary event loop and check the condition lock * Remove workaround in test_futures, no more needed
* asyncio, tulip issue 196: ProactorIocp._register() now registers the overlappedVictor Stinner2014-07-271-15/+38
| | | | | | | | | | | | | | | | in the _cache dictionary, even if we already got the result. We need to keep a reference to the overlapped object, otherwise the memory may be reused and GetQueuedCompletionStatus() may use random bytes and behaves badly. There is still a hack for ConnectNamedPipe(): the overlapped object is not register into _cache if the overlapped object completed directly. Log also an error in debug mode in ProactorIocp._loop() if we get an unexpected event. Add a protection in ProactorIocp.close() to avoid blocking, even if it should not happen. I still don't understand exactly why some the completion of some overlapped objects are not notified.

* asyncio: sync with TulipVictor Stinner2014-07-251-0/+5
| | | | | | | | * Tulip issue #196: IocpProactor._poll() clears the reference to the overlapped operation when the operation is done. It would be better to clear the reference in a new _OverlappedFuture.set_result() method, but it cannot be done yet because of a weird bug. * BaseSelectorEventLoop._write_to_self() now logs errors in debug mode.

| | | | | | | | | | | | * Fix _WaitHandleFuture.cancel(): return the result of the parent cancel() method. * _OverlappedFuture.cancel() now clears its reference to the overlapped object. Make also the _OverlappedFuture.ov attribute private. * Check if _WaitHandleFuture completed before unregistering it in the callback. Add also _WaitHandleFuture._poll() and repr(_WaitHandleFuture). * _WaitHandleFuture now unregisters its wait handler if WaitForSingleObject() raises an exception. * _OverlappedFuture.set_exception() now cancels the overlapped operation.

| | | | | | | | | | | | | | | | | | | | | | Improve stability of the proactor event loop, especially operations on overlapped objects: * Tulip issue 195: Don't call UnregisterWait() twice if a _WaitHandleFuture is cancelled twice to fix a crash. * IocpProactor.close(): cancel futures to cancel overlapped operations, instead of cancelling directly overlapped operations. Future objects may not call ov.cancel() if the future was cancelled or if the overlapped was already cancelled. The cancel() method of the future may also catch exceptions. Log also errors on cancellation. * tests: rename "f" to "fut" * Add a __repr__() method to IocpProactor * Add a destructor to IocpProactor which closes it * _OverlappedFuture.cancel() doesn't cancel the overlapped anymore if it is done: if it is already cancelled or completed. Log also an error if the cancellation failed. * Add the address of the overlapped object in repr(_OverlappedFuture) * _OverlappedFuture truncates the source traceback to hide the call to the parent constructor (useless in debug).

| | | | | | | | | | | | | | | | | | | * Tulip issue #183: log socket events in debug mode - Log most important socket events: socket connected, new client, connection reset or closed by peer (EOF), etc. - Log time elapsed in DNS resolution (getaddrinfo) - Log pause/resume reading - Log time of SSL handshake - Log SSL handshake errors - Add a __repr__() method to many classes * Fix ProactorEventLoop() in debug mode. ProactorEventLoop._make_self_pipe() doesn't call call_soon() directly because it checks for the current loop which fails, because the method is called to build the event loop. * Cleanup _ProactorReadPipeTransport constructor. Not need to set again _read_fut attribute to None, it is already done in the base class.
