It would be nice if the output of Spezial:Linksearch can be filtered for the different namespaces. e.g. show only the article name space of http://de.wikipedia.org/wiki/Spezial:Linksearch/%2A.dyndns.org
Created attachment 2635 [details] Adds a namespace selector to Special:Linksearch
Hopefully this isn't an index problem; on very often-linked sites, picking a rarely appearing namespace could require shuffling through the entire link set in the database.
Namespace filter added with r20144 (In reply to comment #1) > Created an attachment (id=2635) [edit] > Adds a namespace selector to Special:Linksearch Have seen your patch too late. But it works similiar (In reply to comment #2) > Hopefully this isn't an index problem; on very often-linked sites, picking a rarely appearing namespace > could require shuffling through the entire link set in the database. If you are unhappy with this implementation, please revert. Another not so expensive (hopefully) solution is a simple filter main namespace and non main namespace.
thanks for adding the filter, but is has a bug. If you choose talk pages as filter it shows only talk pages but if you click on "next 50" or "show 500" then the parameter "namespace=x" is missing in the link.

It is fixed, but the Wikimedia servers are still on release r20145 (see [[Special:Version]]. A bigger schema change is pending. Be patient please :-)
for the record, reverted, non-trivial optimization to make it happen.
(In reply to comment #9) > for the record, reverted, non-trivial optimization to make it happen. but in general it worked very fine. (i was already wondering why it since some minutes don't work at all..)
Fixed with r21543, but due to MiserMode not available for WMF Wikis :-(
so we have a namespace filter in Special:Contributions, in Special:Recentchanges and in Special:Watchlist (and more?) but it is not possible in Special:Linksearch? hardly understandable.
Presumably the appropriate table isn't currently indexed by namespace.

Shouldn't this bug be reopened ? This feature doesn't seem to be activated on WMF wikis so far.
See comment #11. The feature exists but has not been activated because it's inefficient due to the structure of the table: the table contains an article ID only, with no namespace stored. I admit I don't see the inefficiency in the join: mysql> EXPLAIN SELECT * FROM externallinks WHERE el_index LIKE 'http://com.disney%'; +----+-------------+---------------+-------+---------------+----------+---------+------+------+-------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+---------------+-------+---------------+----------+---------+------+------+-------------+ | 1 | SIMPLE | externallinks | range | el_index | el_index | 62 | NULL | 4 | Using where | +----+-------------+---------------+-------+---------------+----------+---------+------+------+-------------+ 1 row in set (0.00 sec) mysql> EXPLAIN SELECT * FROM externallinks JOIN page ON (el_from = page_id) WHERE page_namespace = 0 AND el_index LIKE 'http://com.disney%'; +----+-------------+---------------+--------+--------------------+----------+---------+------------------------------+------+-------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+---------------+--------+--------------------+----------+---------+------------------------------+------+-------------+ | 1 | SIMPLE | externallinks | range | el_from,el_index | el_index | 62 | NULL | 4 | Using where | | 1 | SIMPLE | page | eq_ref | PRIMARY,name_title | PRIMARY | 4 | wikidb.externallinks.el_from | 1 | Using where | +----+-------------+---------------+--------+--------------------+----------+---------+------------------------------+------+-------------+ 2 rows in set (0.00 sec) But that's another bug. Feel free to open a new bug requesting that this feature be improved to be efficient enough for inclusion on Wikipedia.
Thank you, this is now bug 10593.
