you can see the page is blank on mysite http://see.sl088.com/wiki/Yum_%E8%A2%AB%E9%94%81%E5%AE%9A

Is there any pattern?
Both examples above seem to be page moves / redirects?

On a probably very unrelated note, Firefox browser console lists several errors on the link given in comment 2, for example

• ReferenceError: rm2d_ki101 is not defined (whatever that weird stuff is)
• SecurityError: The operation is insecure in MediaWiki:Gadget-ExtDiscus.js

slboat wrote:

Hmm,I use the counter the server and disqus.

I believe the problem is cause by the last log is move,I found there are 345 blank pages

I'd be interested to know where rm2d_ki101 comes from.

JavaScript error console has nothing to do here IMHO

When you move a page, it creates a new revision, but it doesn't create a new row in the text table, so you end having 2 revisions with the same text identifier.

If deleteOldRevisions.php isn't smart enough to take this into consideration, it may end up deleting the contents of the text table just because it's being referenced by one "old" revision, without checking first if it's also being used by a "current" revision.

yes!you are correct,i believe that's why,that's a big problem,if some not backup but run this script,the clean page never have chance get back.

i wonder why no one report this question,i think it had been a while.

I'm still pending to have time to test this, but if it can delete content from current pages, it's a major bug

now i see the great of open source software!

if i can do any help plz let me know!

Okay, I've tested it and I was unable to reproduce.

I've created a page, and did some edits. Then moved the page (leaving a redirect), ran deleteOldRevisions.php and the contents of the page were still there, and all the page history was deleted (CORRECT).

Then, I performed some more page moves, this time without leaving a redirect, and ran again deleteOldRevisions, and it has the same behavior: page history deleted (only last item is preserved) and the page has the last version of the text.

I've tested that on 1.22 and 1.23. I see your wiki now have 1.23. Was this happening on an earlier MediaWiki version?

How was done the last edit to those articles?

I've tested it by deleting the article, and importing it with Special:Import, then ran the script and still no issues.

them are no such tool,to check which the mediawiki has lost content,so even it lost we cant know,only if we see it.

You could get a list of revisions with missing text using this database query:

select page_namespace, page_title, rev_id from page join revision on rev_page = page_id where not exists (select * from text where old_id = rev_text_id);

thank you!if anything i found i will let you know,so i guess them no more provide to take this as bug yet
