Programmatically abort updates

[dcook]

Is it possible to have a hook in the update workflow that does some validation and aborts the update?
Eg if url_errors.log contains 5xx errors, abort (and send email alert).

Hi Mr. Cook.

You could try using workflow commands which can abort the update if the script returns a non-zero status.

For example, if you want to abort an update after the gather phase on web collection based on url_error.log, you could do the following:

• Create groovy script which consumes url_errors.log and runs the test you need. If the tests do not pass, throw an exception which causes the script to "fail"
• In collection.cfg, reference this script in post_gather_command e.g. post_gather_command=$GROOVY_COMMAND /path/to/script/AbortOnTooManyErrors.groovy

Note: Please pay special attention to the way you specify workflow commands so that you have an easier time during upgrades.

Hope this helps.

Perfect, this sounds very straightforward thanks Gioan!

Just reporting back, I've been able to cause the update to abort by returning an error code from a bash script in a workflow command:
post_gather_command

In the bash file:
exit 1
