Are we able to use extension1 here (that's where we normally have flowdb, except private wikis)?

I know wikitech is special, but don't recall all the details.

No, wikitech cannot depend on extension1.

Flow can be enabled, AFAIK, but it will have to live on its own database (like officewiki or some other one?).

This is to prevent that an outage on the main cluster will not bring down the documentation for it (wikitech/labswiki/silver).

@Krenair would storing in the main db make things easier or harder for the process of mirroring content to https://wikitech-static.wikimedia.org?

Hm, wikitech-static, good point. I don't think it matters as long as all the correct data comes out of MediaWiki's dumpBackup.php script (see modules/openstack/files/mw-xml.sh in puppet for how that's run) and goes back in through importDump.php

We have our own dump script (Flow/maintenance/dumpBackup.php). To do a Flow import, you use the regular import script.

modules/openstack/files/mw-xml.sh in the puppet repository probably needs to be altered then. Is wikitech-static going to need parsoid installed?

See update to the description regarding External Store.

*bump* on this?

@Mattflaschen-WMF So I confirm $wgDefaultExternalStore is false on wikitech.

We can move it a little bit in CS.

@jcrespo Do you prefer to create a new labswiki_flow database for Flow on wikitech, or do you prefer we directly use the labswiki db?

For consistency I'd suggest using the labswiki DB directly, because that's what we do in other places where the central Flow DB isn't used (testwiki and mediawikiwiki IIRC). But if there's a reason why creating a new DB for this is better, then let's do that; I'm just saying that if there's no real difference, we should use the existing DB for consistency.

It's the private Flow wikis (currently just officewiki).

I checked, and this has product approval.

We should either:

• Update wikitech-static scripts immediately

or:

• Make sure the wikitech-static import at least keeps working for the non-Flow pages (temporarily, until we can get the Flow importing as well).

before keeping Flow enabled.

We need $wgFlowDefaultWikiDb to be set before to be able to create the tables:

$ mwscript extensions/WikimediaMaintenance/createExtensionTables.php --wiki=labswiki flow

Warning: Memcached::touch(): touch is only supported with binary protocol in /srv/mediawiki/php-1.28.0-wmf.20/includes/libs/objectcache/MemcachedPeclBagOStuff.php on line 253

This wiki uses  for Flow tables. They don't need to be created on the project database, which is the scope of this script.

Please, just don't. Wikitext talk pages are working just fine. Thanks.
