* QTest::CrashHandler: split into Unix and Windows (1/2)Thiago Macieira2025-05-231-676/+0
| | | | | | | | | | | This file is convoluted and hard to read due to #if all over the place. Let's split the two very different implementations. This is the first commit, which just copies the files around without any changes, to help with Git history.

* QTest::CrashHandler: ask GDB for the memory mapping layout on crash tooThiago Macieira2025-05-191-0/+1
| | | | | | | | | | | | Processes usually crash due to invalid pointers, but sometimes it's hard to know if a given value is valid or not just by eyeballing it. So let's ask GDB to print it. I don't think LLDB has a way to do it. Pick-to: 6.9 Change-Id: I35e35bd3b79eeba49192fffd61474054cd089301 Reviewed-by: Edward Welbourne <[email protected]>
* Fix bad signal restoration which can cause infinite loopEric Beuque2025-02-191-2/+2
| | | | | | | | | | | | This fix the FatalSignalHandler destructor to restore properly the signal handler which cause an infinite loop when a signal is emitted like SIGABRT or SIGINT and when we are using two QTest object in same program.

* Testlib: wrap cycle_p.h headerGiuseppe D'Angelo2025-01-181-1/+1
| | | | | | | | | | | | | The header triggers compile warnings -- -Wundef, to begin with. Since it's included from multiple places, we either fix the header or wrap it. The header isn't maintained upstream (we actually keep patches "on the side"), so I'll go with the wrapping option, and suppress -Wundef in there.

* QTest::CrashHandler: allow debugging crashed tests on Linux+YAMAThiago Macieira2024-09-251-0/+6
| | | | | | | | | | | | | The YAMA LSM by default[1] prevents attaching the debugger to any process that isn't a child. Since our backtracer comes from a child process instead (i.e., tracing the parent), we must grant explicit permission. This also makes QTEST_PAUSE_ON_CRASH=1 work.
