Updating QA crontabs

This page is about changing the nightly cron jobs that run on hgwdev to a controlled fashion.

DO NOT EDIT THE QATEAM hgwdev CRONTAB FILE DIRECTLY

Summary

• Edit (in your home dir): genecats/qa/crontabs/hgwdev.crontab.
• Make a file with the contents of QA Team's hgwdev crontab file, and do a diff with YOUR genecats file you just edited.
• Run a command to update QA Team's hgwdev crontab file so that it reflects your changes.

Steps

Step 1. Go to your genecats repository and do a git pull to bring it up to date.

Step 2. Edit your genecats/qa/crontabs/hgwdev.crontab (add a new cronjob, change an exisiting cronjob, etc.). For example:

MAILTO=braney@soe.ucsc.edu,brianlee@soe.ucsc.edu
HGDB_CONF=.hg.conf.beta

15 03 * * * /cluster/bin/x86_64/hubPublicCheck hubPublic  -udcDir=/data/tmp/qa
16 02 * * * /cluster/bin/x86_64/hgsql -e "select hubUrl from hubPublic" hgcentralbeta | tail -n +2 | while read url; do /cluster/bin/x86_64/hubCheck  -udcDir=/data/tmp/qa $url; done

(Reminder of first numbers: Minute then Hour DOM Month DOW command)

Step 3. In another terminal you can ssh qateam@hgwdev

Step 4. [OPTIONAL STEP, only needed for a new job] If you have a new cronjob, test your changes from qateam, for example in the above run /cluster/bin/x86_64/hubPublicCheck hubPublic -udcDir=/data/tmp/qa and your other commands to see if they will work as expected from the home directory.

Step 5. Commit and push your changes to the genecats repository hgwdev.crontab.

Step 6. This step provides instructions on how to compare YOUR genecats crontab with QA Team's hgwdev crontab. In the qateam@hgwdev window you can output the current crontab with "crontab -l", which essentially creates a copy of the crontab, which does not have your edits yet, because you made your edits in YOUR genecats repo, not to the crontab on QA Team's hgwdev. You can put this in a temp file such as crontab -l > /data/tmp/deleteMe, but it really doesn't matter where you put this file. You could even put it in your home directory, such as ~/temp/crontab.hgwdev

Step 7. Now that you have your comparison file, you can compare the two to be sure your changes are all you are updating (where brianlee is changed to your directory). diff /data/tmp/deleteMe ~brianlee/genecats/qa/crontabs/hgwdev.crontab. Once you do the diff, you should only see the line that you added or edited.

1. From qateam@hgwdev, you now need to update QA Team's hgwdev current crontab by "running" your revised genecats version: crontab ~brianlee/genecats/qa/crontabs/hgwdev.crontab . Now your crontab from your home dir (in the genecats repository) will match the crontab for QA Team's hgwdev.
