| * Plug padding holes in QHostAddressPrivateThiago Macieira2016-06-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ABIs where quint64 is aligned on 8-byte boundaries (such 32-bit Windows and all 64-bit systems), there was a padding hole of 4 bytes between QHostAddressPrivate::a and the anonymous union. If we move the member to after the union, there is no hole anymore. That operation causes the tail padding to grow from 3 to 7 bytes. Since we also don't need full 32 bits for the protocol, we can shrink the structure by 8 bytes on those architectures and by 4 bytes on 32-bit Unix systems.

|/ | | | | | | | | | | | Storing them in a single byte is the first step towards the Short QDateTime Optimization. The bump in the "private version" by 10 is to accommodate possible changes in the Qt 5.7 branch.

* QIODevice: make the read/write chunk sizes configurableAlex Trotsenko2016-01-271-1/+1
| | | | | | | | | | | | | | | By default, the read chunk size is QIODEVICE_BUFFERSIZE and the write chunk size is 0 (which means that we don't use the internal write buffer). Derived classes may override these values to define the size of QIODevice's write buffer or to optimize the read buffer use. 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.

* QIODevice: add infrastructure for multistreamingAlex Trotsenko2016-01-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Trotsenko2016-01-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add a qtHookData field for Qt Creator's data displayhjk2015-09-031-1/+10
| | | | | | | | | | | | | | | Qt Creator needs to be able to determine structure sizes and data member offsets for certain private types even in the absence of debug information. It is sufficient to keep and test the actual data sets on the Qt Creator side, as long library provides a hint which data set is needed. So far, HookDataVersion was meant to be used for that purpose. To make it more explicit, this patch introduce a TypeInformationVersion field in qtHookData.

* Add a more reliable replacement for qt_add/removeObject().Volker Krause2014-04-151-0/+69
These hooks only worked reliably with LD_PRELOAD on Linux/GCC, on other platforms they depended on what exactly the compiler optimizer is doing as well as some nasty assembler rewriting to actually access them. The new system uses a simple array of function pointers that can be set to custom hooks by tools that need this (based on ideas from Andre Poenitz). This also covers qt_startup_hook (similar problem), and the Qt version number that Andre had asked for.
