Ok, I guess I found some kind of a bug. While working on restoring my Wiki manually (restore deleted documents in old space, revise links, delete pages in new space) I ended up being unable to delete a page with attachments. The root error is com.mysql.jdbc.PacketTooBigException: Packet for query is too large (37285720 > 33554432) (see attached log for full http://xwiki.475771.n2.nabble.com/file/n6862011/DeletePageFailure.txt DeletePageFailure.txt stack trace) and it occurs when we try to store the deleted page in [com.xpn.xwiki.doc.XWikiDeletedDocument] I guess the problem is that if e.g. max_allowed_packet 30MB then we can upload 10 files of 30MB in size. But when we later delete the page and it gets stored into recycle bin, max allowed packet is still 30MB while the page is treated as one with all its attachments thus weighing 300MB causing this error. Is my assumption correct? -- View this message in context: http://xwiki.475771.n2.nabble.com/Is-Rename-Space-code-snippet-still-up-to-… Sent from the XWiki- Users mailing list archive at Nabble.com.
