Actually, I'll defer to Aaron Schulz on this (cc'd). Reading the server admin log[1], it looks like he started this on April 24 on "all.dblist", which I'm assuming means a sequential run though all of our dbs. No idea whatsoever what the ETA is for this or how to find out other than asking Aaron.
As Federico pointed out, this is tracked here: https://bugzilla.wikimedia.org/show_bug.cgi?id=36081

That was intended as far as the original deployment. AFAIK, there's a script to backfill values but RobLa should be able to tell you more.

Asher,
As you can see in the conversation below, I discovered that sha1 hashes are not being generated historically for revision content in Wikipedia -- just generated from the time of release (mid-April) forward. Is this intended? If so, is there a plan to fill in the sha1's historically or should we (data monkeys) keep track of THE GREAT SHA1 EPOCH of April, 2012 when performing our analysis from here forward?
Thanks! -Aaron

Hi Aaron,
You are right, it seems not to have been calculated for older pages (I checked it for eswiki). I was under the impression that this either had finished or is in progress. Probably best to ask Asher for more details.
Best,
Diederik

Hey guys,
I'm trying to use the sha1 hashes of Wiki content for the first time (woot! Props to D et al. for seeing it through) but I'm having some trouble actually getting them out of the API/databases. It looks like the checksums only go back to April 19th. Is this true of all pages? Is there any plan to propagate the metric backwards?
