Updates to image, oldimage, and archive tables are being applied on the slave servers. The new additions will: * Speed up user renames * Allow cleaner lookups of uploaded files by name * Store of file content hashes for various purposes * Store page_id of deleted pages for later use in restore or other sorting out of fun situations There will be intermittent slave lag while these run. Once all the slaves are done, we'll have to swap masters and run them on the old masters before updating code. -- brion vibber (brion @ wikimedia.org) _______________________________________________ Wikitech-l mailing list Wikitech-l(a)lists.wikimedia.org http://lists.wikimedia.org/mailman/listinfo/wikitech-l

Are there any proper software mechanisms available, though? _______________________________________________ Wikitech-l mailing list Wikitech-l(a)lists.wikimedia.org http://lists.wikimedia.org/mailman/listinfo/wikitech-l

In the process of disabling this feature, are you going to provide a new way to merge article histories?
