Extension talk:SpecialDeleteOldRevisions2

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)

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)

 * If you still need this, I can add an option. Jehy 03:02, 1 December 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:

(SQL-Abfrage versteckt)

aus der Funktion „“. MySQL meldete den Fehler „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 ', , , , , , , , , , , , , , , , , , , , , , , , , , , 139, 140, 143, 144, 145, ' at line 1 (localhost)“.

Is it possible that this extension does not work for MySQL 5 and above? Or what is wrong?

Thanks for help! -- Roy, 12:05, 22 March 2009 (GMT)
 * Extension works fine for MySQL 5, we need to take a closer look at your problem. Jehy 03:02, 1 December 2009 (UTC)

How to shrink database?
After deleting old revisions from a page, a message is displayed:

Remember to shrink your database after deleting many articles.

How do you shrink the database?

 * I think this is what you need to do:
 * If using MySQL you need to optimize the tables afterwards, you can do that with phpMyAdmin.

Problems downloading extension
It appears as though Jehy's site is gone. Is there a backup site with the code?


 * Maybe its a temp downtime. --Choshi 15:52, 13 September 2009 (UTC)


 * Yeah, sorry for this, all ok now. Thanks for providing backup link. Jehy 03:02, 1 December 2009 (UTC)

pruning revisions using a "pruning date"
Hello,

I am very interested in a single parameter for your extension, a single date to prune (delete) the revision table before that date. I will pay a bounty (give you a donation) for such a modification (stable program version needed). --Wikinaut 22:47, 22 December 2009 (UTC)
 * No problem, just contact me (see in my profile, how) Jehy 13:10, 27 December 2009 (UTC)
