Description Roybb95 2005-05-14 15:17:09 UTC
It would be very usefull if there was special page with a list of all protected
pages.
Comment 1 Ævar Arnfjörð Bjarmason 2005-05-14 15:59:13 UTC
Doing this with the current schema (1.4 and 1.5) is obscenely slow, the
(?:page|cur)_restrictions wasn't designed to be mass searched.

On the 2005-03-09 en.wikipedia dump:
mysql> SELECT cur_title, cur_restrictions FROM cur WHERE cur_restrictions LIKE
'%edit=sysop%';
[...]
297 rows in set (5 min 44.24 sec)
Comment 2 Brion Vibber 2005-05-15 01:27:28 UTC
Would need to add an index on that field, I suppose.

An alternative is splitting the protection to a linked table (perhaps useful for getting at the 
multiple settings in a clearer fashion than the blob we have now).

Comment 4 Borgx 2005-12-02 00:34:54 UTC
is there any progress? 
Comment 5 Filip Maljkovic [Dungodung] 2005-12-02 12:52:00 UTC
A friend of mine made the special page and it looks good IMO (see
http://conversion.vikimedija.org/index.php/Special:Protectedpages). The only
problem Avar suggested to me on the IRC is that the page doesn't support
caching, but I think that's not a hard thing to do. Funny thing - I didn't know
this bug even existed, so I asked Avar to make it. Now there really is a feature
request. Great.

Comment 7 p_simoons 2006-01-12 13:40:16 UTC
As reported on ANI, three admins work daily to keep the manually-generated
[[Wikipedia:Protected page]] up to date with the current situation. Automation
would apparently be a useful timesaver.

*** Bug 6211 has been marked as a duplicate of this bug. ***
Comment 9 Max Semenik 2006-06-06 20:24:32 UTC
And what about my code from Bug 6211? It does not search in page_restrictions, only 
checks length. Is it faster? Can anyone with dumps check?
Comment 10 Darkoneko 2006-06-13 10:40:39 UTC
Now, the same could be asked for the semi-protected pages ;)

If there's a problem about slowness, IMO it's still useful even if the page is
only upgraded every few days or so

Patch

This is a complete patch, ready for commiting. I used the following query:

SELECT 'Protectedpages' AS type, page_namespace AS namespace, page_title AS
title, page_restrictions AS restrictions FROM $page WHERE page_restrictions <>
'' AND page_namespace <> $mediawiki

($page = 'page' normally, $mediawiki = NS_MEDIAWIKI)

and marked it as expensive, because page_restrictions is not (yet?) marked as
index. Running the query on a recent dump of dewiki (couldn't set up enwiki,
too slow to add all these rows) on my computer resulted:

14919 rows in set (8.29 sec)

It seems to be generally OK (my computer is a bit slow - a former test resulted
about 7 seconds), but definitely expensive. For comparison, running the query
of Special:Shortpages on dewiki resulted:

482777 rows in set (6.19 sec)

Two questions:
1. Should I define the caching in some other place?
2. Is it the correct query, or it should be changed somehow?

Thanks.
Comment 12 Aaron Schulz 2006-10-06 18:43:48 UTC
I currently run the bot that has maintains en wikipedia's list of protected
pages for while now. Such a MW feature might be useful, but it will need
protection type filtering for:
*Semi-protected (edit)
*Full-protected (edit)
*Full-protected (move only)

Also, things like redirects and deleted pages (this one might be tricky) would
need to be filtered out. Deleted pages used to *flood* WP:PP until I added a
regexp xml filter check for each page (kind of tedious though) which also checks
for redirects while its at it.

Without these two sets of filters (protection type and redir/DP type) such a
page will be of very limited use on a large wikipedia site, likely not worth
being expensive. However this would be an effective replacement for WP:PP on
smaller wiki sites.

Comment 14 Christopher Hagar 2006-10-14 19:19:23 UTC
As mentioned here,
http://mail.wikipedia.org/pipermail/wikitech-l/2006-October/039204.html, this
page should perhaps be restricted to sysops, at least for semi-protected pages.
Comment 15 Aaron Schulz 2007-01-10 23:59:20 UTC
Perhaps a page_len column or a joint query would help to allow filtering which
pages show on the list to avoid deleted pages from drowing all out.

Patch

page.page_restrictions is no longer used (the table page_restrictions is used
instead). A new patch should be created.
Comment 17 Rotem Liss 2007-01-22 15:10:21 UTC
Werdna added a special page, Special:Protectedpages, in r19561.
