Operator: Anomie (talk · contribs · SUL · edit count · logs · page moves · block log · rights log · ANI search)

Time filed: 03:59, Tuesday January 7, 2014 (UTC)

Automatic, Supervised, or Manual: Automatic

Programming language(s): Perl

Source code available: User:AnomieBOT/source/tasks/BrokenRedirectDeleter.pm

Function overview: Delete broken redirects

Links to relevant discussions (where appropriate): Wikipedia:Bots/Requests for approval/Yet Another Redirect Cleanup Bot, WP:BOTREQ#Deletion of broken redirects

Edit period(s): Periodic

Estimated number of pages affected: However many broken redirects people create. Currently there are about 48.

Exclusion compliant (Y/N): Yes

Adminbot (Yes/No): Yes

Already has a bot flag (Y/N): No

Function details: The bot will do the following:

  • Attempted interwiki redirects are replaced with {{soft redirect}}
  • Other broken redirects are deleted if the following are true:
    • The redirect has only 1 revision OR was created more than 4 days ago (or some other suitable delay determined by the community, at minimum 24 hours)
    • The redirect is not in the User or User talk namespaces
    • The target page has no log entries less than 12 hours ago
    • The redirect has 10 or fewer incoming links (number may be adjusted by community consensus)
    • The bot is not excluded, e.g. with {{nobots}}
  • When a broken redirect is deleted, any subpages, and the talk page (if any) and its subpages will be deleted, unless:
    • The page is a talk page with an existing subject page
    • The page is tagged with {{G8-exempt}}
    • The page has more than 10 incoming links (number may be adjusted by community consensus)
    • The bot is excluded, e.g. with {{nobots}}
    • The parent subpage wasn't deleted
  • Skipped redirects will be reported to User:AnomieBOT III/Broken redirects

This is, of course, a replacement for User:Yet Another Redirect Cleanup Bot and will be an adminbot. Anomie⚔ 03:59, 7 January 2014 (UTC)[reply]

Anomie has written a number of bots and has proven a conscientious operator. Whilst this is a rewrite (presumably due to unavailable source of the existing bot), and their first adminbot, I have faith in studious deployment. However, given I'm unable to review the work of the bot, I'd be at a disadvantage if I approved a trial. Sysop BAG members who may be around and interested could include Quadell, MBisanz, Jarry1250 or better yet Chris G (operator of Yet Another Redirect Cleanup Bot).

The rewrite is more because I prefer to run everything under the same bot framework rather than under a hodgepodge of different code in different languages; the source for Y.A.R.C.B. was available until sometime yesterday, and that's where I picked up the "10 or fewer incoming links" condition. Anomie⚔ 12:36, 7 January 2014 (UTC)[reply]
The trial could be to report which pages the bot would delete, if necessary. Anomie⚔ 12:36, 7 January 2014 (UTC)[reply]

There is a strong community consensus (see Wikipedia:Requests for adminship/RedirectCleanupBot) for this task to be performed by an adminbot - thank you Anomie for agreeing to take it on.
I would propose reducing the condition "The redirect was created more than 4 days ago" to "24 hours ago". This waiting time was not a feature of the original bot and no issues were encountered as a result. If the redirect has only one revision, creation a couple of days ago should prevent deletion - it will most likely result from an article being created with a typo/miscapitalisation and being renamed before being speedy deleted for not meeting Wikipedia's inclusion criteria. No need for such redirects to hang around for 4 days. If for some reason someone has created a redirect to an article they will create later, 24 hours should be more than sufficient. WJBscribe (talk) 11:06, 7 January 2014 (UTC)[reply]

The 4-day waiting period was part of Y.A.R.C.B. I'm a bit wary of following the example of a bot that last ran 5 years ago over one that ran until last year, although I also have no opposition to adjusting the delay (within reason, 24 hours I think would be the minimum) based on a consensus at someplace like WP:AN or WP:VPR. Anomie⚔ 12:36, 7 January 2014 (UTC)[reply]
The four day waiting period was for deleting pages that had more than one revision. --Chris 02:25, 8 January 2014 (UTC)[reply]
Looking at the code, it seems that it will refuse to delete anything newer than 4 days, and I just misread the BRFA about the "1 revision" thing. Anomie⚔ 02:35, 8 January 2014 (UTC)[reply]
I am comfortable with this task, either at the 4 day or 24 hour timing. How would you like the trial to proceed? Should a crat temp-flag the bot or are you comfortable running it on your main account with a unique deletion summary? MBisanz talk 02:24, 8 January 2014 (UTC)[reply]
Either way is fine. But first I think I'll adjust things slightly based on what Chris G pointed out above. Anomie⚔ 02:35, 8 January 2014 (UTC)[reply]
OK, if it's redirects with more than 1 revision, I agree that we should wait at least 4 days. But no need to wait for 1 revision redirects. WJBscribe (talk) 13:43, 8 January 2014 (UTC)[reply]
Agreed. The only potentially-concerning way to get a broken 1-revision redirect is if someone does page-move vandalism and then someone moves it to a different title for some reason (either move-without-redirect or immediately delete the resulting redirect at the bad title) and fails to clean up any existing redirects to the bad title. And I doubt that happens often enough to worry about. BTW, the changes I mentioned at 02:35 are done now (and were as of about 2:48). Anomie⚔ 14:16, 8 January 2014 (UTC)[reply]
Approved for trial (50 edits or 5 days). Please provide a link to the relevant contributions and/or diffs when the trial is complete. on your existing admin account with a deletion summary linking here. MBisanz talk 01:06, 11 January 2014 (UTC)[reply]
Trial complete.. Edits are here, deletions are here. The bug with the bot status page placing ">1 revision and <4 days old" under the "Skipped" section rather than the "Recently changed" section is already fixed, BTW. Anomie⚔ 03:56, 13 January 2014 (UTC)[reply]
If a malicious user replaced an obscure page with a deliberately broken redirect, and it went without detection for 4 days, would any safeguards be able to prevent its deletion? Jackmcbarn (talk) 00:28, 19 January 2014 (UTC)[reply]
The 4-day waiting period is the safeguard, along with the bot logging such redirects. Anomie⚔ 01:14, 19 January 2014 (UTC)[reply]

{{BAGAssistanceNeeded}} Trial was completed, but nothing was said from any BAG member. 46.107.88.236 (talk) 16:49, 24 January 2014 (UTC)[reply]

 Approved. MBisanz talk 01:59, 26 February 2014 (UTC)[reply]
