Alexander Shorin updated COUCHDB-991:
-------------------------------------
Component/s: View Server Support
> Native query server show function does not respect os_process_timeout setting
> -----------------------------------------------------------------------------
>
> Key: COUCHDB-991
> URL: https://issues.apache.org/jira/browse/COUCHDB-991
> Project: CouchDB
> Issue Type: Bug
> Components: Database Core, View Server Support
> Affects Versions: 1.0.1
> Environment: Mac OSX 10.6; CouchDB/1.0.1 (Erlang OTP/R13B)
> Reporter: Paul Mietz Egli
>
> I have a design document containing show functions written in Erlang for
> performance reasons, and I found that some calls to these shows were timing
> out after about eight seconds (according to curl). I increased
> os_process_timeout to 300000 but still saw the show timing out after seven or
> eight seconds. Log shows:
> {exit, {timeout, {gen_server,call, [<0.135.0>,{prompt,[my data]}]}}}
> I asked about this problem in IRC, and kocolosk said that the problem is that
> couch_native_process only checks the timeout for a couple of commands, like
> list_row. The gen_server:call/2 function is timing out because
> ddoc(...<<"show">>) is taking more than five seconds to process. Changing
> line 63 to the following prevents the timeout:
> gen_server:call(Pid, {prompt, Data}, infinity)
> Ideally, though, each run/2 call in couch_native_process would respect the
> configured timeout value. Workaround for now is to wrap the
> ddoc(..<<"shows">>..) call in a timer using State#evstate.timeout as a
> duration (thanks for the solution, kocolosk!).
