* QIODevice: handle incomplete readsAlex Trotsenko2016-01-121-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a transaction mechanism that gives the ability to read the data atomically. Current implementation supports transactions for both types of devices. For sequential devices, it records the whole input stream during transaction. For random-access devices, device position is saved when transaction starts. If an error occurs, the application may be able to recover the input stream by rolling back to the start point. Also, QIODevice::peek() was rewritten to make use of transactions internally. The replacement of QIODevicePrivateLinearBuffer by QRingBuffer is closely entangled with that, which makes it unfeasible to do separately. Bump the TypeInformationVersion field in qtHookData, to notify the Qt Creator developers that the offset of QFilePrivate::fileName was changed and dumpers should be adapted. [ChangeLog][QtCore] Added QIODevice's startTransaction(), commitTransaction(), rollbackTransaction(), isTransactionStarted() functions to support the read transactions.

| | | | | | | | | | | | | On Unix we get a detailed error message when a process fails to start, but later on we overwrite it with a generic "Process fails to start". Fix this by keeping the original error message (if one is available). This fixes a regression introduced in commit 5147f73ac3.

* | Use forkfd in QProcessThiago Macieira2015-01-231-7/+6
|/ | | | | | | | | | | | | | | | | | | | Replace the existing code in QProcess that dealt with signaling of child processes exiting with forkfd and spawnfd. The previous code was convoluted and hard to maintain, having shown its age in the last year. I've been running it for a year and a half and the new implementation is definitely an improvement. 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 Macieira2014-06-121-9/+19
| | | | | | | | | | | | | | | | | | | | | | 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.

* Don't try to read from invalid file descriptors in QProcessThiago Macieira2014-06-121-0/+3
| | | | | | | | | strace reveals that we do ioctl(-1, FIONREAD) and get EBADF. The only case where this could happen is inside _q_processDied, which calls the read functions without checking if the pipe is still open.

* Rename QProcessPrivate::destroyChannel to closeChannelThiago Macieira2014-06-121-7/+7
| | | | | | | | | | | The QProcessPrivate::Channel object contains some structures that may survive the closing of the pipe, so calling this function "destroy" is incorrect. Let it be just the closing. For symmetry, the createChannel() function is renamed to openChannel().
