Description

The VisualEditor backend on WMF production sites should no longer use RESTbase.

Rationale: This will remove one of the primary consumers of the parsoid endpoints on RESTbase, and one of two reason we need to store pre-generated parsoid output on restbase (the other reason being PCS, for now).

  • beta (some) T320531
  • testwiki and labtestwiki T320531
  • officewiki
  • labswiki (aka wikitech)
  • mediawikiwiki
  • hewiki
  • small wikis
  • medium wikis
  • enwiki
  • all wikis

Relevant configuration:

$wmgUseRestbaseVRS= false;
NOTE: Notify the community via TechNews when this is happening!

Deployment to enwiki is looking good. Client side latency didn't change, server side performance got a good boost:

VE has been switched to direct mode on all wikis as of 13:20 UTC. So far, all metrics look good.

Screenshot 2023-06-15 160036.png (953×1 px, 199 KB)

Client side activation latency was unaffected. Utilization of the RESTbase API dropped to nearly zero, as expected. The remaining calls are from ongoing eiting sessions and should be gone within 24 hours.

Screenshot 2023-06-15 160120.png (951×1 px, 188 KB)

Server side latency of the VE API modules went down as expected, since direct mode removes the overhead of connecting to RESTbase. getPageHTML didn't benefit much got a bit slower (from 88ms up to around 100ms) since it now needs to load data from ParserCache, but HTML-to-wikitext fransformation became significantly faster, going from 270ms down to 110ms. This would benefit switchoing from visual to source mode, and should also improve save times.

Screenshot 2023-06-15 160146.png (903×1 px, 162 KB)

Stash write rates more than doubled, as expected based on the number of edits on the wikis where direct mode was previously disabled. The write rate went from about 60 to roughly 150 writes per minute. This change however barely registers on the database cluster that backs the stash: write operations on the x2 cluster remained stable at about 1500 per minute, replication lag was unaffected.

I am curious if the phab metrics are affected by the Country protection list - there is ruwiki (one of top-10 of projects) - thus silently disregarded.

Because ever since the event - a mass problem reported at the local techforum, see (in Russian) Википедия:Форум/Технический#Визред - with VE stopped to load completely.

It look like besides other changes ve.init.Target.actionGroups stopped to work.

Or your metrics are fine and it is just a fraction of ruwiki VE users (represented at the techforum) who are affected.

My metrics only show that loading VE dodn't get slower - it would not show VE failing to load.

Thank you for the report!

@Neolexx I have just successfully made a couple of edits on Russion wikipedia using Visual Editor: https://ru.wikipedia.org/w/index.php?title=%D0%A3%D1%87%D0%B0%D1%81%D1%82%D0%BD%D0%B8%D0%BA:DKinzler_(WMF)/Sandbox&action=history

If VE is failing, please file a separate bug report. You can tag me on the report, and also link to this task if you think it is related. Please include as much information as possible in the report.

matmarex added a comment.EditedJun 15 2023, 8:02 PM

@Neolexx That seems like an unrelated problem. I think this might be caused by change https://gerrit.wikimedia.org/r/c/mediawiki/extensions/VisualEditor/+/928049, which slightly changed how the VE toolbar is defined.
