cron: respect PATH from login.conf

2020-03-30T03:26:52Z

As a followup to the use of login.conf environment vars (other than PATH) in cron, this patch adds PATH (and HOME) to the list of login.conf settings respected. The new logic is as follows: 1. SHELL is always _PATH_BSHELL unless explicitly overridden in the crontab file itself; no other settings are respected. This is unchanged. 2. PATH is taken from the first of: crontab file, login.conf, _PATH_DEFPATH 3. HOME is taken from the first of: crontab file, login.conf, passwd entry, unset 4. The current directory for invoking the command is taken from the crontab file's value of HOME (existing behavior), or the passwd entry, but not anywhere else (so it might not equal HOME if that was set in login.conf).

cron(8): convert vfork() usage to fork()

2020-02-10T02:40:23Z

vfork() is error-prone, and the usage here definitely grew to not be clearly OK given vfork-semantics; e.g. setusercontext(3) within the child. Rip out vfork() and the rest of the references to it. fork is heavier, but it's unclear that the difference will be all that obvious. Reported by: Andrew Gierth and sigsys@gmail.com

cron: add log suppression and mail suppression for successful runs

2019-09-25T02:37:40Z

This commit adds two new extensions to crontab, ported from OpenBSD: - -n: suppress mail on succesful run - -q: suppress logging of command execution The -q option appears decades old, but -n is relatively new. The original proposal by Job Snijder can be found here [1], and gives very convincing reasons for inclusion in base. This patch is a nearly identical port of OpenBSD cron for -q and -n features. It is written to follow existing conventions and style of the existing codebase. Example usage: # should only send email, but won't show up in log * * * * * -q date # should not send email * * * * * -n date # should not send email or log * * * * * -n -q date # should send email because of ping failure * * * * * -n -q ping -c 1 5.5.5.5 [1]: https://marc.info/?l=openbsd-tech&m=152874866117948&w=2 PR: 237538 Submitted by: Naveen Nathan Reviewed by: bcr (manpages) MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D20046

Add new functionality and syntax to cron(1) to allow to run jobs at a

given interval, which is counted in seconds since exit of the previous invocation of the job. Example user crontab entry: @25 sleep 10 The example will launch 'sleep 10' every 35 seconds. This is a rather useless example above, but clearly explains the functionality. The practical goal here is to avoid overlap of previous job invocation to a new one, or to avoid too short interval(s) for jobs that last long and doesn't have any point of immediate launch soon after previous run. Another useful effect of interval jobs can be noticed when a cluster of machines periodically communicates with a single node. Running the task time based creates too much load on the node. Running interval based spreads invocations across machines in cluster. Note that -j/-J won't help in this case. Sponsored by: Netflix
