Subject [jira] Updated: (COUCHDB-992) replicator doesn't respect .ini settings for http sources
Date Tue, 21 Dec 2010 08:05:00 GMT


Randall Leeds updated COUCHDB-992:

    Attachment: 0001-respect-replicator-config-settings-COUCHDB-992.patch

Here's the patch.

couch_rep_reader no longer sets these settings when init is called, leaving it to the http_db
record to hold the correct defaults.

I changed the #http_db record to use the defaults that had been forced by couch_rep_reader
before. I thought this was safest. Since each replication between two hosts will open as many
as 100 requests at a time any change which lowered the default value of (sessions x pipeline_size)
could cause user's replications to experience a regression of surprising back-off or even

Each replication reader registers on config changes too, so it should be possible to change
how many sessions continuous or long-running replications are using without restarting them.

Thankfully, I think most of this goes away with the new replicator, but since that's not default
yet I propose this for backport to 1.0.2 and 1.1.

Unfortunately, I actually have a situation where a pre-release xulrunner-devel on my system
is preventing CouchDB from compiling. I'll have to open a separate ticket for that, but please
forgive me if this patch contains some tiny syntax error. I wanted to file it before I forgot
