Possible fixes:

  • Increase LUASANDBOX_MAX_TIMERS until the error no longer appears. Repeat as necessary in the future. Cost appears to be around 56 bytes each, per thread, FYI.
  • Finish Gerrit change 159822, currently stalled on looking like it's needing a good-sized chunk of complicated code to be written/imported and tested.

@JanZerebecki explained that the actual "No tests executed" error is unrelated to the "timer" messages.

Dynamically allocate luasandbox_timer instances

hoo raised the priority of this task from Medium to High.Jun 1 2015, 7:08 PM

Patch got merged, but I guess a new php-luasandbox deb needs to be packaged. Raising priority as this is disrupting both Scribunto and Capiunto tests.

I created T101275 to track the work of creating new debs and deploying them to Jenkins.
