* Fix non implicit job lease detectionChristian Kögler2020-09-061-1/+2
| | | | | | | | | | | If a job is non implicit, the job lease will never be written back via function vacate. The information non implicit is wrongly derived by the counter implicit_jobs, which will never be negative and therefor run_script is always called with implicit job true. This fix checks if implicit is possible before procuring the job lease. Closes: #5 [via git-merge-pr]
* use blocking/nonblocking reads instead of poll(2) v0.2Leah Neukirchen2020-06-261-10/+5
| | | | | | | | | | | | | | | Previously, we used a blocking fd for the token pipe and used poll(2) to see if anything could be read right now in try_procure(). However, there is a race between poll(2) and the subsequent blocking read(2), which can result in processes deadlocking when multiple instances of redo poll at the same time. Instead, we now make the fd nonblocking when needed, so that the read either reads or returns immediately if there is nothing to read. Closes #3. Closes: #4 [via git-merge-pr]

| | | | | | | | Else, a dependency to a subdirectory would change into it, but then look up the subdirectory-relative names in the .dep file according to the dir_fd of the parent. Now, we keep dir_fd updated, and ensure after each .dep line we return to it.
