At the very least, let's delist it from SpecialPages... (patch)

One downside to my approach is that, with less traffic, the extension will deteriorate even faster and we'll risk losing the ability to easily produce the archived, static dump.

Deteriorate even faster? Nobody's been making fixes for our version of it in forever...

Provide a configuration option to delist Special:CodeReview

We should probably set up some general-purpose redirects so catch all the old incoming traffic (of which there's a ton of links that will break).

Rewrite old Special:Code urls to Phabricator SVN clones

Too soon for redirects.

Hi. Unfortunately, this was an extension that I have used on my server. I came to reinstall it after a recent Ubuntu update caused my post-commit hooks to freeze up (and break Apache in the process), and saw the header on the extension page.
Is there any fork in development for this extension?

@BFeely file a task about that under the CodeReview project. It's just unused at Wikimedia, not deprecated or archived. In fact, I think @ashley uses it still?

At this point, I am re-deploying it on my newer MediaWiki instance, starting from scratch. I will see if the freezeups go away. I won't be able to test fully of course until I push my next commit.

As a heads-up, I have determined the freeze is not due to the extension but the svn command itself freezing up.

I just posted a test commit on my new CodeReview instance and it completed without issue, though I did have quite a few freezes of the SVN command during the initial import.

@BFeely: Hi and welcome! This task is about removing that extension from being available on WMF websites (but not about removing its code repository). Please file a separate task at https://phabricator.wikimedia.org/maniphest/task/edit/form/1/?projects=mediawiki-extensions-codereview about any problems with running that extension on your server - thanks a lot!

@Krinkle please file a new task for the Code-Stewardship-Reviews instead of hijacking this one.

I believe T222918: Put "shim" code for namespaces, logs, and log i18n into WikimediaMessages so we can undeploy extensions is not a blocker for this because CodeReview did not add any logs nor namespaces to mediawiki.org. The only thing it added were some API modules and the special page. The API modules will obviously break, and we're going to preserve the special page links via Apache rewrites.

Ah, right, cool. :-)

T243055 is done, but I am guessing dropping the table data is blocked on T205361?

Dropping the table is blocked on this task (as otherwise it'll cause a fatal when anyone tries to load https://www.mediawiki.org/wiki/Special:Code/MediaWiki/1 etc.); this task is blocked on that and the Apache redirects so that the pages keep working, if we're going to do that.
