This sounds similar to Bug #1394, although being more general. Could these Bugs/Requests for features be merged
or mor clearly separated? It's not exactly a duplicate.

Hmmm, yes, they are rather similar. The main similarity is in what is needed for
them - both need something to search all databases rather than just one,
although this one would need a special field for interwiki-links too. Once those
have been implemented (which might be hard, I suppose, to do in a not-too-slow
manner), both can easily be implemented.

I'd say you might need a few fields, or maybe even its own table would be best.
Having a separate table would make for a cleaner implementation and you could have a whack of indices to speed queries along nicely.

I think images and articles could be both served by this table...

How has MW changed since April '05, that would help or hinder the resolution of this bug?

Adding "whatlinkshere" to summary for better searching.

• Bug 12830 has been marked as a duplicate of this bug. ***

The Commons part has been solved by GlobalUsage.

However a global "WhatLinksHere" to see incoming links from all wikis, doesn't exist yet.
Perhaps a similar thing called GlobalLinks ?

Global Link Search:

A tool that does what Special:LinkSearch does, but on all projects and languages.

Need to have:
Total number of links.

Nice to have:
Total number of links per project in one table.
Total number of links per language in one table.
Total number of links per project and language in one table.
From the last table, links to each "local" Special:Linksearch.
All links in one table order by number of occurencies descending.
Languages/projects with no links could be left out of the tablee instead of showing "0".

My suggestion is related, but I was mostly curious about external links i.e. showing links to a specific external website. But perhaps, if done in a general way, that wish could be solved by this issue.

Note, there is now interwiki stuff in the api:

All links to wikibooks using b prefix: https://en.wikipedia.org/w/api.php?action=query&list=iwbacklinks&iwblprefix=b

All interwikis on main page:
https://en.wikipedia.org/w/api.php?action=query&prop=iwlinks&titles=Main%20Page

There's not really any special page web interface to this though that i am aware of...

Of course doing this in a cross wiki fashion (anything that links to this specific page from any other wiki) is much harder.

We did talk, and there is a tool on the toolserver for that. But :

Global Link Search:

... that is about external links, this bug is about interwiki links
(http://example.org vs. [[x:foo]])

To keep these issues separated, I started https://bugzilla.wikimedia.org/show_bug.cgi?id=38405 for the Global LinkSearch.

Of course, before we have a cross-wiki one. We should first have a local wiki one.

See T68293 (bug 66293).

Removing the Possible-Tech-Projects tag as we are planning to kill it soon! This project does not seem to fit in the Outreach-Programs-Projects category in its current state, so I am not adding that tag right now!

Another use case for a generalized 'whatLinksHere' -- seeing where a tabular data file is used?

Hmm. I can almost see how to do this the slow way: just ask all the wikis. But this can't possibly work for e.g. multilingual interproject links, since the wiki containing the link only knows about the first prefix, and then the rest are all HTTP redirects :-(. I think it'd require a quite substantial change to interwiki link semantics (and implementation) to get anything really useful here. (Hopefully, this could be done without actually screwing up any of the actual links ...)
