I created an article 'G' with text 'g', deleted it, and now this is in the database: select * from text where old_text='g'; +--------+----------+-----------+ | old_id | old_text | old_flags | +--------+----------+-----------+ | 1031 | g | utf-8 | +--------+----------+-----------+ select * from revision where rev_text_id=1031; Empty set (0.00 sec) select * from page where page_title='G'; Empty set (0.02 sec) select * from archive where ar_text='g' or ar_title='G'; Empty set (0.00 sec) The text should be in table 'archive', not in 'text'. I can reproduce this error, but sometimes it works normally. I am not sure about the exact circumstances.
Text is no longer removed on deletion; this is necessary to keep block-compression from exploding, and working cleanly with other backend storage changes in progress or to be made. I've checked in a fix to make this work properly. page and revision entries are removed, and archive entries retain the original revision.rev_id and text.old_id; revision records are recreated on undelete, while text records are retained, and simply not visible except through the sysop's undelete interface or the raw database.
