* Fix usage of condition variable in TQThread which could lead to a thread ↵Michele Calgaro2025-03-231-3/+5
| | | | | | | | | | | | being run multiple times in parallel. Although highly unlikely, the following situation was possible: - a thread is restarted while still running. The call to the second 'start()' blocks because the thread is still running - the OS decides to randomly wake up the thread that called 'start()' - a second thread is started and runs in parallel to the first thread, with obvious undefined behavior Signed-off-by: Michele Calgaro <michele.calgaro@yahoo.it> (cherry picked from commit 3143d2d40ab5af1053596cd9b46c7034f22c4624)

* Make sure to release thread resources back to the OS once the thread completes.Michele Calgaro2024-10-031-0/+1
| | | | | | | | | | Threads created with pthread are created in detach mode. Threads created using glib thread functions are instead created as joinable. The fix makes glib-created threads detached, so that the thread resources are released when the thread completes. This resolves TDE/amarok#30 and will benefit any place where a TQThread is used.

* Improve handling of the global post event list in order to minimize possible ↵Michele Calgaro2024-08-293-77/+92
| | | | | | | | | | | | | | | crashes on exit. Key points: 1. a TQPostEventList can now have an associated mutex, which is used in case of the global post event list (GPEL) 2. the lifetime of the GPEL is no longer associated to the lifetime of the TQApplication object, but rather extended to the lifetime of the main thread. The GPEL is a static local initialized on first access and destroyed when the global static object destructor is invoked 3. access to the GPEL after the TQApplication object has been destroyed has been minimized by protecting calls in ~TQObject() and ~TQWidget(). 4. special care was taken not to affect performances or unnecessarily create tons of unused TQMutexes This replaces PR #182. Technically it is still possibly unsafe due to the order of destruction of the globat static objects not being guaranteed across multiple compilation units, but the aforementioned changes should minimize (possible to zero) the chances of a SEGV happening.

* Fix TQThreadStorage destruction in the main threadAlexander Golubev2024-03-185-2/+47
| | | | | | | | | | | | | | | | Before that the allocations of TQThreadStorage objects from the main thread were never destroyed and memory associated with them were never freed. The second one isn't a huge problem as at that point program is terminating anyway (but it still makes valgrind complain). The first one is the bigger issue as destructors might contain some essential external cleanups like removing temporary files. Also make `TQApplication::guiThread()` return `0` when the thread is destroyed (may happen on the program exiting during destruction of statics).

* Fix compilation with -disable-inputmethod and -no-inputmethodAlexander Golubev2024-03-084-5/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | As for now here are two sets of inputmethod options: - -enable-inputmethod/disable-inputmethod - which seems to supposed to control whether build the 'inputmethod' module or not - -inputmethod/-no-inputmethod - which seems to supposed to enable/disable inputmethod support without changing the ABI. Before the patch both -disable-inputmethod and -no-inputmethod were just breaking the build: -no-inputmethod were disabling some code with support for the module, but didn't disabled the module build itself nor build of plugins. -disable-inputmethod were disabling build of plugins and module, but didn't disabled code depending upon it. It seems the inputmethod support were still WIP when the last release of Qt3 came to be, hence the mess. This patch fixes the build if both -disable-inputmethod AND -no-inputmethod are supplied. Disabling only one is not enough due to tqmake/configure have problems handling two different options of the same name. Later the -inputmethod/-no-inputmethod should be probably removed entirely.
