Great. It sounds like I don't need my patch. I have since found the page on the wiki which documents this feature. It crept into 1.1.1 without me noticing. http://wiki.apache.org/couchdb/Performance#JavaScript_View_Server Unfortunately I've now tried using this option and it doesn't help even if I set it to crazy sizes like 1G. I have isolated the offending document (22M of JSON) and have been running couchjs manually on it but I get 'out of memory' no matter what I do. I also tried applying my original patch but that didn't help either (which is good in some sense). So for the moment I have trimmed down the document and updated it in the database and my views are building once again. It only seems to be one document out of ~80 million so far and I guess sometimes life is too short. > >Re custom patches on build-couchdb, simplest approach is to fork, apply >your patch to a custom branch and then use something like: > > rake git="git://me.github.com/couchdb.git a_fork" install=a_spoon That sounds like a good solution. I'll do that if I need my own patches in future. Thanks a lot (and Jason too), Paul. ________________________________ Sophos Limited, The Pentagon, Abingdon Science Park, Abingdon, OX14 3YP, United Kingdom. Company Reg No 2096520.
