Queue up jobs to be run later.
Jobqueue can be used to simpy 'put' and 'pop' jobs to run later. You can also 'lease' a job for a given timeout. If the task ends successfully you can mark it as 'done'; if it fails, you can mark it as 'exit'.
Jobqueue is useful to keep track of which jobs you've run and whether they were OK, failed or timed out.
# Load up some jobs
jobqueue put echo foo
echo 'echo bar "baz quux"' | jobqueue put
# Simple pop
$(jobqueue pop) # outputs: 'foo'
# Lease example
job_id=$(jobqueue lease -t 20) # lease a job for 20s
$(jobqueue get $job_id) # outputs: 'bar "baz quux"'
status=$?
if [[ $status -eq 0 ]]; then
jobqueue done $job_id
else
jobqueue exit $job_id
fi
Jobs are stored in sqlite as follows:
$ echo "SELECT * FROM Jobs;" | sqlite3 .jobsQueue -cmd ".header on"
Id|Details|Created|Status|Timeout
1|echo foo|1441582092|UNKNOWN|0
2|echo bar "baz quux"|1441582098|DONE|1441582133
pip install git+https://github.com/bewt85/jobqueue.git
If you need to include -h or --help in your job, you need to pass it
via stdin.
