* nq: use shared locks when waiting for other lockfilesDuncan Overbruck2021-03-131-4/+4
| | | | | | | | The nq process itself will hold an exclusive lock on its lock file, the other nq processes will now use a shared lock to test if the previous queue item is still locked. By using shared locks, multiple nq processes testing the same shared lock don't interfere with other nq processes checking for locks.
* nq: check d_name fits into newestlocked (our filenames always will)Leah Neukirchen2021-03-131-1/+2

* nq: revamp waiting loop to avoid busy loops in contested casesLeah Neukirchen2021-03-131-18/+27
| | | | | | | | | | | | | | | | | As reported in #37, the current rewind-loop has the issue of waiting for a lock on the first file that is locked, but it could be detected as being locked by another process that also just wants to check this file. As both processes rewind the dir and retry in this case, this can yield a busy loop. Instead, find the newest locked file and wait for that. This should result in most nq processes waiting for different locks, so this kind of synchonization cannot appear. In theory, removing the rewinddir would be enough, as later nq runs should not result in enqueuing earlier jobs, but it's better to be safe and check there are no more locked files before we launch our job.
* nq: don't define _XOPEN_SOURCELeah Neukirchen2018-03-071-2/+0
| | | | | This hides LOCK_* on FreeBSD and OpenBSD, and is not needed anyway. Closes #26.

| | | | | | | `nq -q` could trigger a segfault before. Found by Leonardo Taccari. Fixes #25.

* nq.c: fix time_t overflow on 32-bit machinesLv Zheng2015-08-111-1/+1
| | | | | | | In systems where time_t is defined as 32-bit integer, the multiplication by 1000 to get millisecond will cause an integer overflow. Fix this problem by explicit integer conversion.
