MediaWiki Job Queue

From WikiMLT

I'm writ­ing this ar­ti­cle at the time while mi­grat­ing this wi­ki from Me­di­aWi­ki ver­sion 1.38 to ver­sion 1.39. Ac­cord­ing to the Cir­rusSearch extension's page and I was in need to mi­grate from Elas­tic­search ver­sion 6.8.23 to ver­sion 7.10.2.

So af­ter in­stalling Elas­tic­search ver­sion 7.10.2, in­stead fol­low­ing the Up­grade man­u­al I've Re­build the Elas­tic­search da­ta from scratch which leads me to an in­fi­nite MediaWiki's Job queue. For this rea­son I was need to get much fa­mil­iar with the MediaWiki's main­te­nance scripts re­lat­ed the Job queue.

If it is a wi­ki fam­i­ly, you may need to spec­i­fy the $wiki­Id, like be­low.

sudo -u ${OWNER} php "${IP}/maintenance/showJobs.php" --wiki="${wikiId}"

Man­age Jobs

Re-push aban­doned jobs of cer­tain type.

sudo -u ${OWNER} php "${IP}/maintenance/manageJobs.php" --type typeName --action "repush-abandoned"

Delete Jobs of cer­tain type.

sudo -u ${OWNER} php "${IP}/maintenance/manageJobs.php" --type typeName --action "delete"

Use showJobs.php –group, as it is shown above, to find avail­able job types in the cur­rent job queue. Note the quote marks at the ac­tion op­tions in the ex­am­ples above are used here just for bet­ter high­light.
