* Add QIODevice::NewOnly and QIODevice::ExistingOnly OpenMode flagsd3fault2018-01-171-1/+3
| | | | | | | | | | | | | | | | When QFile::open is called with the NewOnly flag, the call will fail if the file already exists. As usual, if the file does not exist, it will be created. Like QTemporaryFile, there is a guarantee from the operating system that you are not accidentally creating a new file on top of an older file. When QFile::open is called with the ExistingOnly flag, the call will fail if the file does not exist. The ExistingOnly flag only provides new functionality when used with the WriteOnly flag. For ReadOnly it provides no change in functionality, as ReadOnly by itself already never creates.

* QIODevice: add infrastructure for multistreamingAlex Trotsenko2016-01-271-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some sequential devices allow data to be partitioned into several channels that have the property of independently sequenced delivery. Supporting such devices uniformly requires a unified API which provides the user with a uniform concept of multistreaming. This patch is based on QProcess's multiplexing model and introduces the following features: - ability to get the number of channels; - multiple internal read/write buffers; - channel selection functions; - notification signals on channel activity. To keep the source code compatible with single-channel implementations, introduce a private class that references the current read buffer and hides multistreaming internals from the user. 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 multistreaming to QIODevice.

* QIODevice: handle incomplete readsAlex Trotsenko2016-01-121-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination.
