* Centralize the implementation of move assignment operatorsGiuseppe D'Angelo2020-10-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment we have two main strategies for dealing with move assignment in Qt: 1) move-and-swap, used by "containers" (in the broad sense): containers, but also smart pointers and similar classes that can hold user-defined types; 2) pure swap, used by containers that hold only memory (e.g. QString, QByteArray, ...) as well as most implicitly shared datatypes. Given the fact that a move assignment operator's code is just boilerplate (whether it's move-and-swap or pure swap), provide two _strictly internal_ macros to help write them, and apply the macros across corelib and gui, porting away from the hand-rolled implementations. The rule of thumb when porting to the new macros is: * Try to stick to the existing code behavior, unless broken * if changing, then follow this checklist: * if the class does not have a move constructor => pure swap (but consider ADDING a move constructor, if possible!) * if the class does have a move constructor, try to follow the criteria above, namely: * if the class holds only memory, pure swap; * if the class may hold anything else but memory (file handles, etc.), then move and swap. Noteworthy details: * some operators planned to be removed in Qt 6 were not ported; * as drive-by, some move constructors were simplified to be using qExchange(); others were outright broken and got fixed; * some contained some more interesting code and were not touched.

| | | | | | | | | | [ChangeLog][QtCore][QStorageInfo] Added QStorageInfo::subvolume(), which returns the name of the subvolume of a volume that was mounted, if one was detected. This is currently implemented only for btrfs on Linux.

| | | | | | | | | | | | | | | | | | 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 Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>
* Add the QStorageInfo classIvan Komissarov2014-08-131-0/+122
Allows to retrieve information about mounted volumes such as label, total/available size, filesystem type and so on. Possible use cases are: - allows to do checks about filesystem before performing actual operation (such as available/maximum volume size) - allows to retrive information about volume that can be shown in file dialogs - allows to retrieve volume for specific path and check if two or more paths belong to the same volume or not [ChangeLog][QtCore] Added QStorageInfo class to retrive information about mounted volumes and drives Change-Id: Ibf9c2e6b53ef39c5605894a4422acdbbca4030c4 Reviewed-by: Shawn Rutledge <shawn.rutledge@digia.com>
