* Apple: Use POSIX IPC instead of System V in sandboxed applicationsTor Arne Vestbø2021-06-161-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | System V semaphores are not supported in sandboxed applications, so when Qt is configured with App Store compliance, or the user requests POSIX IPC explicitly, we use that instead. https://developer.apple.com/library/archive/documentation/Security/Conceptual/AppSandboxDesignGuide/AppSandboxInDepth/AppSandboxInDepth.html#//apple_ref/doc/uid/TP40011183-CH3-SW24 As the shared memory name limit on Apple platforms is very low, we have to skip the existing logic for naming, and instead use a truncated hash of the key. This should still be fine for avoiding any collisions in practice. An explicit check for the ENAMETOOLONG error has been added to catch any cases where they key goes beyond the allowed length. Sandboxed applications also have an extra requirement that the key must include an application group identifier. This requirement has been pushed up to the user and documented, as we don't have enough information in Qt to know which identifier to use. Both tst_QSystemSemaphore and tst_QSharedMemory work as before with both sandboxed and non-sandboxed applications, after removing some assumptions in tst_QSharedMemory about System V behavior.

* Windows: Don't cause a malloc before calling GetLastError()Andy Shaw2015-03-161-2/+2
| | | | | | | | | | When creating a string it would cause a malloc which would reset GetLastError() so we need to ensure that GetLastError() is the first thing it calls if a Windows API call fails.

* Update copyright headersJani Heikkinen2015-02-111-7/+7
| | | | | | | | | | | | | | | | | | 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 Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination.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>
