Issue #1353

Updated by cduryee about 6 years ago

When using the export distributor with the "start_date" parameter, the distributor will fail with an exception if there are no rpms or errata associated with the repo since start_date.

For example:

<pre>
pulp-admin rpm repo create --repo-id zoo --feed https://repos.fedorapeople.org/repos/pulp/pulp/demo_repos/zoo/
pulp-admin rpm repo sync run --repo-id zoo
# this works
pulp-admin rpm repo export run --repo-id zoo
# this fails
pulp-admin rpm repo export run --repo-id zoo --start-date <utc date after the time of the last sync>
</pre>

Here is the stack:

It would be better if the task succeeded (with an appropriate message) and simply did not create an export ISO.
