| * QWindowsPipeWriter: ensure validity of the write bufferAlex Trotsenko2016-04-301-10/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QWindowsPipeWriter uses asynchronous API to perform writing. Once a cycle has been started, the write buffer must remain valid until the write operation is completed. To avoid data corruption and possibly undefined behavior, this patch makes QWindowsPipeWriter::write() take a QByteArray, which it keeps alive for the duration of the write cycle.

| * Remove QPROCESS_USE_SPAWN and all that it surroundsJames McDonnell2016-03-221-185/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The spawn code was only used to make QProcess work on QNX 6.5.0. Fork works on QNX 6.6.0. The QNX spawn implementation has a flaw that causes a deadlock in certain situations. When a working directory is specified for the process, the QNX spawn implementation stops all threads except the one doing the spawn so that it can temporarily change the process' working directory. This can lead to a deadlock if the thread does anything that conficts with something being done in a stopped thread. QNX 6.5.0 is no longer supported in Qt 5.6.0 so we can just switch QNX to the fork implementation and get rid of the spawn implementation. Made a QNX specific adjustment to the hardExit test. There's a bug in the OS that the test can run into because it does something that normal applications wouldn't.

This change replaces support for the QNX Neutrino spawn() call with the POSIX version. We lose the ability to do setsid(), but we gain quite a few ioctls() that were done to fill in the file descriptor mapping structure. That's also the only OS for which we have the ability to thread-safely chdir() before the call to spawnfd(). Another advantage is that forkfd does not require a dedicated thread running to handle child processes exiting.

* QProcess: Handle spurious socket notifications for stdout and stderrThiago Macieira2014-06-121-0/+4
| | | | | | | | | | | | | | | | | | | | | | On Unix systems where the GUI event dispatcher uses a notification system for socket notifiers that is out of band compared to select(), it's possible for the QSocketNotifier to activate after the pipe has been read from. When that happened, the ioctl(2) call with FIONREAD might return 0 bytes available, which we interpreted to mean EOF. Instead of doing that, always try to read at least one byte and examine the returned byte count from read(2). If it returns 0, that's a real EOF; if it returns -1 EWOULDBLOCK, we simply ignore the situation. That's the case on OS X: the Cocoa event dispatcher uses CFSocket to get notifications and those use kevent (and, apparently, an auxiliary thread) instead of an in-thread select() or poll(). That means the event loop would activate the QSocketNotifier even though there is nothing to be read.

* do not use fileno calls in forked childJoerg Bornemann2014-03-061-4/+4
| | | | | | | | | | | | | | | | | | | | This fixes an issue that causes QProcess::start to silently fail on OS X 10.9. Apparently, fileno(stdout) locks the handle on OS X 10.9. It may happen that the parent process fflush()s stdout while the child has just been forked. The stdout lock of the parent is never released in the child and fileno(stdout) therefore locks forever. According to the fork documentation on opengroup.org one may only call async-signal-safe functions between fork and exec in the child. The fileno() function does not appear in the list of async-signal-safe functions. Also, fileno(stdout) and friends can be easily replaced by the standard constants STDOUT_FILENO etc. Done-with: Fawzi Mohamed <fawzi.mohamed@digia.com> Task-number: QTBUG-37306 Change-Id: I2b1f5f47cc48a1ad020fb0493a955d2bc27aeb47 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
