Hi all,First post to the list. I've got a bunch of questions, and I hope this isthe right place to ask them.I'm interested in the idea of wiki 'mirroring': updating a second wiki ('B')periodically with content from wiki A. (There's of course some discussion ofthis on the web, so I'm aware that there's been quite a bit of thinking onthis already, but I couldn't quite find the solution I was looking for.)A first stab at mirroring would be to do a Special:Export on the whole of A,and then do a Special:Import on B. But this becomes impractical for largerwikis: Ideally, I just want to update what needs updating.The best way to do this would probably be something like list=recentchanges(going back to the date of last transfer). Of course this doesn't work,because recentchanges are are periodically purged, so cannot be used betweenarbitrary dates. The log doesn't seem to record edits (is this correct?), sothis can't be used to get a list of changes between two arbitrary dates.So, question 1: Is it possible to get a list of all changes (includingedits) between two dates (in a single query)?If one wanted the complete version history, then another way to do thiswould be to get all revisions since the last transfer made, i.e. somethinglike:action=query&prop=revisions&revids=1450|1451|1452|...&rvprop=content(then transform xml to Special:Import format, and upload). Together with aquery of the log, this would give you all changes.But suppose the wiki is very active or you don't have much bandwidth or yousimply don't want the whole version history, but just the latest versions(since the last transfer). The only way I can see is to do something likethis: - 1. Fetch the list of namespaces - 2. Get the list of revisions in each namespace (action=query&prop=revisions&generator=allpages for each namespace) - 3. See what needs updating, and then fetch all the changed pages.Question 2: Can you see a better way of doing this? Also, why won'tgenerator=allpages work across namespaces? (I guess there my be a reason whythat isn't possible to do easily.)One way would be to try something like:action=query&prop=revisions&generator=allpages&rvstart=20090521000000but this doesn't work.So, my question 3: Do you know why this doesn't work? I assume there isn'tan efficient mysql query to accomplish this, or are there other reasons?Finally, I guess I am wondering whether there are people actively interestedin discussing issues around wiki mirroring/synchronisation more. If so,what's the best mailing list for this?Sorry, the post got a bit longer than I expected - thanks for consideringthis!All the best,Bjoern
