Add PosixSignalNotifier utility class to covert POSIX signals to
Qt signals and allow qTox to quit appropriately on Linux, FreeBSD
and macOS.
Might protect from data corruption bugs when application is being
terminated during I/O.
Fixes: #4470
Fixes#1926 : When an IPC event was processed locally, if the window was closed before the core could start, the event handler would be forever stuck in the background waiting for the core to start. We fix this by substituting QApplication::quit() by a Nexus::quit() function and a Nexus::isRunning() function, which gives us a condition for exiting blocking processEvents() loops. We cannot simply use QApplication::quit(), because this function has no effect before the start of the event loop.
The problem was further exacerbated by the Tox URI event handler being (incorrectly) blocking. The IPC owner would block in this event handler, and the sender of the event would give up waiting and process the event itself a second time, potentially triggering the first bug. We fix the event handlers accordingly to be (mostly) non-blocking.
Also fixes a related deadlock between ~Core and ~Profile in the case of an early exit
Revert needed, since otherwise there is no way to do automatic sorting
of includes.
Also reverted change to the docs, as leaving it would make incorrect
docs.
In case of conflicts, includes were sorted according to the coding
standards from #3839.
This reverts commit b4a9f04f92.
This reverts commit 5921122960.
In cmake builds, `__FILE__` is the absolute file path. In qmake, it's a
relative path. For in-tree qmake builds, it would be `"src/..."`, for
out of tree, it could be `"../src/..."` or `"../qTox/src/..."` or any
other relative path depending on how qTox was built. This change
normalises them to paths based in src.
Previously HiDPI support is conditionally enabled based on compilation
parameters as well as environmental variables which makes binary
distribution difficult. This commit automatically enables runtime DPI
scaling if Qt supports it (version 5.6 and beyond).
This is to prevent log files from ever exceeding a limit of 1MB each. Only the current and one other log file are kept, giving hopefully enough history for any neccessary debugging.
* Removed duplicate code of ipc event sending
* Removed duplicate code of profile loading
* Fixed bug where activating existing instance still started new instance of qtox asking to select a profile
* IPC messages are now profile-aware and are sent to instance that runs specified profile in -p flag or to ipc owner if -p is not specified.
If -p flag is specified ipc events will be send to instance which runs specified profile. If instance using that profile does not run - new qTox instance will be started. This works with password-protected profiles too - new instance will handle "uri" or "save" events after accepting user password.
