This avoids all the problems with using signals. In practice, all supported platforms were probably using the non-signal tickers already, which is probably why we do not get lots of reports about deadlocks and other weirdness: we were definately using functions that are not async signal safe in the tick handler (such as fflush to flussh the eventlog). Only Solaris was explicitly using the timer_create ticker impl, and even Solaris could probably use the pthreads one (if anyone cared: Solaris is no longer a Teir 3 supported platform). Plausibly the only supported platform that this will change will be AIX, which should now use the pthreads impl. - - - - - 51b32b0d by Duncan Coutts at 2026-04-01T19:01:52-04:00 Tidy up some timer/ticker comments elsewhere - - - - - 7562bcd7 by Duncan Coutts at 2026-04-01T19:01:52-04:00 Remove now-unused install_vtalrm_handler Support function used by both of the signal-based ticker implementations. - - - - - 6da127c7 by Duncan Coutts at 2026-04-01T19:01:52-04:00 No longer probe for timer_create in rts/configure It was only used by the TimerCreate.c ticker impl. - - - - - 3fd490fa by Duncan Coutts at 2026-04-01T19:01:53-04:00 Note that rtsTimerSignal is deprecated. - - - - - 63099b0f by Simon Jakobi at 2026-04-01T19:02:39-04:00 Add perf test for #13960 Closes #13960. - - - - - f1428321 by Matthew Pickering at 2026-04-02T14:01:46+02:00 bytecode: Add magic header/version to bytecode files In order to avoid confusing errors when using stale interface files (ie from an older compiler version), we add a simple header/version check like the one for interface files.
