* Make watchdog kills use a distinct Unix signal and ExitStatusRobert Griebl2025-06-061-0/+13
| | | | | | | | | | | | | By raising an otherwise unused system signal (*), the System UI can now distinguish between crashes, forced kills from the sys-ui and also kills by the watchdog. (*) SIGSTKFLT on Linux x86 and ARM and SIGEMT on Linux MIPS, BSD and QNX. Change-Id: I5cdb9084c1f822c36d24cbb0905479e18a3f1b69 Pick-to: 6.10 Reviewed-by: Dominik Holland <[email protected]>
* Crashhandler: reinstall ourselves, if our handlers got disconnectedRobert Griebl2024-10-291-36/+87
| | | | | | | | | | | | One example is Squish which resets ALL signal handlers to default, if it is instructed to NOT handle signals (this is actually a bug in Squish). Since we have to live with these kinds of tools, the better option is to check at runtime, if the AM's handler got disabled.

There are a few limitations, e.g. filesystem mount monitoring and startup timer are not supported and there's only a rudimentary stack trace in case of a crash, etc. Since Qt Network doesn't provide a HW address and there's currently a cross-compilation issue, the following options need to be passed to configure: -DINPUT_hardware_id=dummyHwId -DQT_FORCE_BUILD_TOOLS=ON Change-Id: Ia58d09d15a781666fe788f21dfe9c7af7a2a74ef Pick-to: 6.4 Reviewed-by: Qt CI Bot <[email protected]> Reviewed-by: Robert Griebl <[email protected]>

* Fix glibc compatibility problemRobert Griebl2021-11-301-1/+1
| | | | | | | | | | | | | | | | | | | | | glibc 2.32 deprecated sys_siglist: the symbol is not available to link against anymore, but it is available at runtime for apps that have been linked against an older glibc version. Our problem is now that the CI builds release version of the AM against an older glibc, which works for the appman binary itself, but if you want to compile a custom appman executable on a modern, glibc 2.32 based system, you get a "missing symbol" linker error in libQt6AppManCommon.a(unixsignalhandler.cpp.o) Detecting this at runtime would be a nightmare for little gain, so we fall back to using the non-async-signal-safe strsignal() function when initially building against a glibc < 2.32.
