Description lɛʁi לערי ריינהארט 2005-05-07 06:51:43 UTC
Halló,

I experienced in many Wikimedia Foundation wiki's that categories have been
added to EXISTING templates.

So far I do not know another method then making a minor change to the page
containing that MODIFIED template.

a) NEIGHTER purge will help
b) NOR deleting and restoring the page

Nevertheless if the problem affects HUNDEREDS of pages an automated method
should be available.

c) it would be usefull that purge should update the membership in the category
so that if you load the category page after, you will see the page purged before

d) if a page is restored the membership in the category should be updated so
that if you load the category page after, you will see the page restored before

f) if there are reasons not to modify action=purge then a more effectiv action
like action=update should be implemented

Regards Reinhardt

One way to rebuild categories is to run the refreshLinks.php maintenance script.
This is a very expensive operation. I do not believe there is any way of
effectively updating a single category listing without looking through the text
of /all/ articles.

I agree that there should be an action for a page to cause it to rebuild all
related index entries - text index, links, category links, etc. Although this
won't solve the problem of out-of-date category listings, at least it would make
it possible to manually update it without having to open each page and save it
again.
Comment 2 Richard J. Holton 2005-05-09 14:54:17 UTC
What might make more sense for dealing with category entries in templates would
be to have a refresh option associated with the template page. This could cause
a category refresh for all pages that include that template. However:

- You can have nested templates. This complicates the process.
- For each page that transcludes the template directly or indirectly, the entire
page has to be parsed (including all transclusions) for category membership.
This is, as they say, "non-trivial".
- Some templates are transcluded into a huge number of pages. Consider {{stub}}
on en.wikipedia.
Comment 3 lɛʁi לערי ריינהארט 2005-06-14 13:31:34 UTC
note on comment 0 item f)

comparing the "''actual code of a page''" (and knowing how it interpreted in the
wiki system) whith the result from action=purge and the known workarounds to fix
related bugs these can be split in:

a) requiring one (minor) edit to get the requested result
example(s):
bug 1119: Page move updates categories with sorting tweak
...

b) requiring more (minor) edits to get the requested result
example(s):
bug 1993: Categories added to templates are not added to including pages
 duplicate of 39: changes to links in a template do not update 'links',
'categorylinks', etc for pages including it
bug 2258: Category links in image upload summary field have wrong sort key
bug 2327: sort key is not evaluated again if a page is moved
bug 2331: undeleting pages does not add the pages to categories
...

If you are not shure what is necessary to do (remove the categories and insert
them back again) you will need more (minor) edits. In addition a lot of
verifying and possible purging will be necessary.

The correct implementation of a more effectiv action=update or action=rebuild
should be a powerful workaround for all these situations. It is a "handling
tool" not a fix for the mentioned bugs.

removed
http://jadesukka.homelinux.org:8180/mediawiki15c/index.php?title=Luokka:Stub&action=purge
because the Nike's test wiki *Betawiki* is behind a firewall
new URL
http://yi.wiktionary.org/w/index.php?title=template:word&action=history

changing to *enhancement*

Hallo!

Is there anything new about this issue?
At
http://yi.wiktionary.org/wiki/special:Recentchangeslinked/category:1
you can see that minor edits are required to *"update category membership"*
whenever the *basic template* is changed.
At the beginning there are quite a lot of changes:
http://yi.wiktionary.org/w/index.php?title=template:word&action=history

Providing this enhancement would limit the number of revisions and keep the
database small storing *onlyreal* content changes.

Comment 6 lɛʁi לערי ריינהארט 2006-02-09 07:29:27 UTC
Same as
Bug 1119: Page move updates categories with sorting tweak
this bug is "half" fixed; see:
http://test.wikipedia.org/wiki/User:Gangleri/tests/bugzilla/02098
'A bugzilla 02098' was created and moved to 'B bugzilla 02098'

http://test.wikipedia.org/w/index.php?title=Category:Bugzilla&action=purge
action=purge was enough to see 'B bugzilla 02098' at letter B *no* "minor edit
was required any more.

What is still required is to "clear the cache for the category page".

The difference between bug 1119 and bug 2098 was:
bug 1119 did not specify the existance of a sort key
bug 2098 did specify a sort key which changes with pages moves

(In reply to comment #6)
This was posted at the wrong place. Now at bug 2327 comment 6.

bug 1119 and bug 2327 do not require an action=update or action=rebuild any more

This might still be required for
Bug 3622: "Rollback doesn't roll back category sort key"
Bug 4713: "Moved pages dissapear from "Whatlinkshere" of templates they include"
Comment 8 Rob Church 2006-02-09 20:44:24 UTC
Duping this up to 4857 since the daemon described there would handle this.

*** This bug has been marked as a duplicate of 4857 ***
