clock_nanosleep (CLOCK_PROCESS_CPUTIME_ID) fails with EINVAL #2116

Open alexrp opened 7 years ago

alexrp commented 7 years ago

Microsoft Windows [Version 10.0.15063]

Calling clock_nanosleep with clock_id = CLOCK_PROCESS_CPUTIME_ID.

It returns EINVAL. It should work as it does on Linux.

strace output for the profiler is huge, so here's the relevant bit:

clock_nanosleep(0xfffffffa /* CLOCK_??? */, TIMER_ABSTIME, {0, 41250000}, NULL) = -1 EINVAL (Invalid argument)

The issue can be reproduced by building Mono and running the profiler test suite, like so:

$ ./autogen.sh
$ make
$ cd mono/profiler
$ make check

(You might need to sudo apt install mono-complete to bootstrap the build.)

You'll see something like:

alexrp@alexrp:~/mono/mono/profiler$ make check
make  check-local

Altering Mono to use CLOCK_MONOTONIC makes the profiler tests pass, but this is not a great solution as we specifically want the semantics of CLOCK_PROCESS_CPUTIME_ID.

Thanks for reporting the issue. Currently wsl only supports a subset of the clokc_nanosleep clock ids and I confirmed CLOCK_PROCESS_CPUTIME_ID is not currently supported. Please give us feedback on UserVoice so we can prioritize appropriately, https://wpdev.uservoice.com/forums/266908-command-prompt-console-bash-on-ubuntu-on-windo.
