Adding externallinks.el_from_namespace on wmf databases
Closed, ResolvedPublic
Actions

Description

With https://gerrit.wikimedia.org/r/#/c/163470/ there should be a new column on the externallinks table which is called el_from_namespace. Please add the new column to production to allow merging of that patch set in the future.

This is the first step for merge of that patch set. After the column is added the patch set can be merged.
After merge and deployment on all wikis the maintenance script "populateBacklinkNamespace.php --tables externallinks" needs to be run.
After the run on all wikis the config $wgUseExternallinksNamespaceDBField can be set to true (in mediawiki/core or in operations/mediawiki-config).

@Springle: Any vague ETA, now that five weeks have passed?

The schema change is now complete.

The other steps in this task probably deserve their own tasks, or else reassigning this one...

Thanks for the schema change. I will open new task(s) as needed. First the patch set needs merging and deployment.

This is not done. The column does not exist on labswiki.

labswiki will run updater after pull of the last changes from master and than the column will be there.

Only production needs manual database changes, because there are some big databases in there.

labswiki is part of the normal production deployment system. I don't think we run update.php there.

Okay, that I was not aware of. I was assuming the same behaviour like beta wikis (http://de.wikipedia.beta.wmflabs.org).

@Springle can you have a look? Thanks.

Checked with @jcrespo, it's just 26k rows and on wikitech (no replication or major traffic to worry about), so no problem, done.
