Extension talk:SpecialDeleteOldRevisions2

Does not work with Postgres (Fixed)
If the extension is used with a Postgres database as backend, the following error occurs:

A database error has occurred Query: SELECT rev_id FROM revision,page WHERE (rev_id NOT IN ( 10918, 10950, 10977, 6545, 7219, 5893, 6399, 1655, 10411, 1931, 2704, 7876, 7882, 7878, 7880, 6702, 6909, 6910, 6950, 6705 ) AND rev_timestamp <= '20100311999999') AND (rev_page = page_id AND page_title LIKE 'Z%') Function: Database::select Error: 1 ERROR: invalid input syntax for type timestamp with time zone: "20100311999999"

Obviously, '20100311999999' isn't a valid date. I assume MySQL is doing some magick behind the scenes so that it works nevertheless. Why is the '999999' appended anyway? Because just removing them seems to work fine.
 * Fixed in 1.4.1 Jehy 01:40, 23 March 2010 (UTC)

I still get a similar error select rev_id FROM revision,page WHERE (rev_id NOT IN ( 2704, 1655, 10411, 1931, 7876, 7878, 7880, 7882, 6702, 5893, 6705, 6545, 10950, 6399, 6909, 6910, 7219, 10918, 10977, 6950 ) AND rev_timestamp <= '20100413235959') AND (rev_page = page_id AND page_title  LIKE 'Z%'); ERROR: invalid input syntax for type timestamp with time zone: "20100413235959" Assing a space between the day and the hour works fine: "20100413 235959"

 * Thank you for your reply. Could you tell me more - what type of field is used for storing this timestamp in postgres? In MySQL, it is binary field and obviously I can't add this space... Possibly, there is some workaround using mediawiki functions. Jehy 00:10, 16 April 2010 (UTC)

80.65.225.88 09:18, 24 July 2010 (UTC)

Putting a space doesn't work with me (I use mediawiki 1.15.4 with PostgreSQL 8.3.7, and version 1.4.1 of this extension). This is how rev_timestamp is defined:

Column          Type                         Not Null     Default rev_timestamp   timestamp with time zone     NOT NULL Sample value: 2010-07-23 19:27:15+00

hope this helps.

80.65.225.88 09:54, 24 July 2010 (UTC)

Well. As a quick workarround, I replaced line 486: $maxDate = str_replace('-','',$this->mRequest->getText( 'wpMaxDate' )). ' 235959'; with: $maxDate = $this->mRequest->getText( 'wpMaxDate' )) . ' 23:59:59+00';

Next error is:

I guess this extension was written with MySQL in mind. Postgres doesn't support DISTINCTROW. By the way, I may be wrong, but it seems that DISTINCT is more appropriate in your script (I'm not MySQL nor PHP fluent, but it looks like you want to build a set as a filter, and DISTINCTROW may return useless duplicates).

The extension seems to work with Postgres when you change (line 103): $res = $dbw->query( "SELECT DISTINCTROW rev_text_id FROM $tbl_rev" ); with: $res = $dbw->query( "SELECT DISTINCT rev_text_id FROM $tbl_rev" ); and (line 111): $res = $dbw->query( "SELECT DISTINCTROW ar_text_id FROM $tbl_arc" ); with $res = $dbw->query( "SELECT DISTINCT ar_text_id FROM $tbl_arc" );

Table Optimization in 1.4.3 Breaks it Further (Fixed)
The added "Optimize Table" loop breaks it for any database other than MySQL, since MySQL specific commands are used. Other databased either have other methods to "optimize" tables or don't need that step at all.

Query failed: ERROR: unrecognized configuration parameter "tables" in /var/www/wiki/htdocs/mediawiki/includes/db/DatabasePostgres.php on line 580

I have commented out the optimization loop around line 369 to get it working.
 * Thanks, fixed this in 1.4.4 - now extension detects database type. Also, replaced "distinctrow" with "distinct" - it's really better, and it bugged you ealier :)Jehy 23:47, 20 September 2010 (UTC)

Keep at least five or ten revisions, regardless of date
I would like to keep at least five or ten revisions per article. Regardless of how old the next-to-lat revision was. If Mr. Schmidt would add that function I would be grateful. Otherwise, I might take a look at how 'maxdate' is handled and add a 'maxcount' for this purpose. Thanks for making this extension. --John S. Peterson 16:25, 7 February 2010 (UTC)

I agree, an option to leave the last 5 or so revisions would be really helpful and add great value to this extension. -Seb

Thanks
Great job. Thanks! It works fine on Mediawiki 1.14.0 with MySql 5.0.67-0ubuntu6 Enzo

Deleting only archived revisions
Is there any possibility of modifying this to allow deleting only deleted revisions, that is, the "archived" revisions that can be selected in the current version of the extension?

There are some times when it is helpful to keep a history, but when one would like to delete garbage revisions (e.g., revisions made during testing) and keep the size of the database down. Currently, first, I delete the page, then restore the revisions I want to keep, then I run the following MySQL queries, but they don't seem to get everything:

To list the deleted revisions:

SELECT `tblprefix_archive`.`ar_text_id`, `tblprefix_archive`.`ar_title`,`tblprefix_text`.`old_id`,`tblprefix_text`.`old_text`, `tblprefix_revision`.`rev_id` FROM tblprefix_archive, tblprefix_text, tblprefix_revision WHERE ((`tblprefix_text`.`old_id`=`tblprefix_archive`.`ar_text_id`) AND (`tblprefix_text`.`old_id`=`tblprefix_revision`.`rev_id`)) ORDER BY `tblprefix_text`.`old_id` DESC

To delete them:

DELETE FROM tblprefix_archive, tblprefix_revision, tblprefix_text USING tblprefix_archive, tblprefix_revision, tblprefix_text WHERE WHERE ((`tblprefix_archive`.`ar_text_id` >0) AND (`tblprefix_text`.`old_id`=`tblprefix_archive`.`ar_text_id`) AND (`tblprefix_text`.`old_id`=`tblprefix_revision`.`rev_id`))

Is this a reasonable approach that gets all the old text (and all references to it) out of the database?

If you don't have time to change the extension, I'd appreciate any tips about how I could modify the extension myself (or at least fix my SQL queries), but I'm more of a "front-end" user - I don't know much about PHP or MySQL.

Thanks! --Fungiblename 19:51, 2 February 2009 (UTC)

Strange error message
Hello, I get an error message, when trying to use this tool. the error message is partially in german language:

Es ist ein Datenbankfehler aufgetreten. Der Grund kann ein Timeout sein, der Ausfall eines Servers oder auch ein Programmierfehler. Die letzte Datenbankabfrage lautete:

pruning revisions using a "pruning date"

[FIX] The latest change conflicts with HTMLForm at least here
Hi, I'm the guy that had made the change for SVN above recently.

In 1.4.1, at least in a local windows installation, HTMLForm.php isn't properly read so the wiki fails to load [with PHP Fatal error: Class 'DeleteOldRevisions_HTMLForm' not found].

However, it is fixed if also HTMLForm.php is renamed to DeleteOldRevisions_HTMLForm.php and that is also reflected in the appropriate 'require_once'. --Athinker 21:50, 6 April 2010 (UTC)

PS. What is also peculiar is that it worked if there was no rename and Class was returned to previous; Apparently there was already an HTMLForm on the system used correctly.


 * That's because you didn't overwrite HTMLForm.php with newer version at first time. In 1.4.1, file name for inclusion is "HTMLForm.php" and the class name is "DeleteOldRevisions_HTMLForm" - everything is fine with it. Jehy 16:20, 7 April 2010 (UTC)
 * That can clearly not be the case since I renamed it and included it and it worked. If I renamed it and included the same old file it wouldn't work since it would call a wrong function.

For me it doesn't even appear in special pages, it worked fine in 1.15.5. I am bureaucrat.

Not deleting old versions of in the File namespace
I installed this extension with a view to deleting old versions of files (Images). I ran the extension which worked perfectly in removing the revision history from pages, but looking at File pages, the old versions are still there. This means when I clean out the images/archive directory I will have pages linking to non-existant files.

Extension name in Special Pages List

Preserving page history but not revisions?
How about only deleting the data in the field 'old_text' (table `mw_text`) for old revisions, instead of deleting that whole row? This will preserve the page history and still reduce the DB size. The links wont work any more or perhaps will only show changes from 0 Bytes to the next but thats ok. I really dont like loosing the page histories. --Choshi 02:15, 12 September 2010 (UTC)
 * Hi. I don't see any meaning to this:) Why do you want to preserve editing metadata but not revicions itself? What use has metadata without the article text? Jehy 09:41, 14 September 2010 (UTC)
 * With what it is right now, everything is deleted. We dont know when the page was created and who edited and when. The only thing we have left is the last editor. All other information is lost. Often we want to see who has edited the page and when, when it was created. If the diff link doesnt work, thats still ok because we would have at least some information in the history. So if the field 'old_text' (table `mw_text`) was set to null or zero, that would do the job. I believe in that way, you would also not have to change/delete any other tables since the main data that takes up space has been deleted and we keep everything else.
 * What do you think? I understand this means changing a code a lot and maybe you dont agree this is a good way. I'll try to play with your code and see if I can come up with something. The way I would do it is: 1) set old text = '0/null' 2) add "diff not available (article size in KB)" in the end or start of the edit summary of that certain revision to let people know they cant see the changes, but everything else is still there. --Choshi 15:20, 15 September 2010 (UTC)

Response to error reports above
If anyone encountered an error during installation (a blank screen, for instance), then there may be a simple mismatch between the names of the files you downloaded and the lines to be inserted in localsettings (which is case sensitive). Rename the folder ("specialdeleteoldrevisions2") to "SpecialDeleteOldRevisions2" and if you're still experiencing trouble, rename the line beginning "require_once" as follows:
 * require_once( $IP.'/extensions/SpecialDeleteOldRevisions2/SpecialDeleteOldRevisions2.php');
 * to
 * require_once( "$IP/extensions/SpecialDeleteOldRevisions2/SpecialDeleteOldRevisions2.php");

Two questions
Regards, Cavila 20:15, 25 January 2011 (UTC)
 * 1) When an article title is specified for "View content page", the query finds no old revisions and nothing is deleted. Is that normal?
 * 2) If an article was last revised before the cut-off date, will it still preserve the latest version (I guess so but I'm asking just make sure).

Empty table handling
If you misspell the name of the article to one that does not exist, you get an "undefined variable" error message ('$cur').

Likewise, if it's not in the archive, for '$arc'. (MW 1.16.2, MySQL 5.1.30)

Mickeyf 18:59, 14 February 2011 (UTC)

Just try this right before the line where the error occured in SpecialDeleteOldRevisions2.php:

if (!isset($cur)) $cur = NULL;

This could be repeated for the variables $oldText, $old, $arc

 * The buttons labels are garbled. Specifically, the button for "delete old revisions" button shows the label  (exchange the colons for semi-colons. I was having formatting issues). I would assume that &lt and &gt are some representation of "<" and ">".
 * The "test only" command seems to work properly.
 * The "delete old revisions" button hangs on a blank screen. Reloading shows that it has not deleted the old revisions.

SQL syntax error on MediaWiki 1.15
SELECT old_id FROM `text` WHERE old_id NOT IN ( 16911, 16912, 17340, 17518, 17519, ..., 20148,, 17820, 18752, 1325, 1326, 17758, 130, 17538, 17619, 16853, 16861, 16862, 16863, 19922 ) ... 1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' 17820, 18752, 1325, 1326, 17758, 130, 17538, 17619, 16853, 16861, 16862, 16863,' at line 1 (localhost)“.

See the empty value between 20148,, 17820

Any idea, what is wrong ? This Wiki has 20159 revisions in the database for a few content pages. I think, something went wrong with the database in the past, but I do not know what. I wanted to use SpecialDeleteOldRevision2 to get rid of all old revisions.

Content pages	44 (All pages in the wiki, including talk pages, redirects, etc.)	244 Uploaded files	88 Page edits since the wiki was set up 20,159 <<<< this is very strange and certainly wrong Average edits per page	82.6
