Hi all,

I'm beginning to get familiar with the administrative functions of couchdb 0.11
and had a question about rev limits and compaction.  In my testing it seems
rev limits are being reset to the default 1000 after I run _compact, even
though the wiki states otherwise:

"_revs_limit defines a upper bound of document revisions which CouchDB keeps 
track of, even after Compaction"
http://wiki.apache.org/couchdb/HTTP_database_API#Accessing_Database-specific_options

For instance if I run the following series of curl commands that create a new 
db,set the revs limit, get the revs limit, run compact, and get the revs limit 
again I see that the revs limit gets reset.

Searching jira for "_revs_limit" doesn't return any results,  so if anyone could 
shed any light on the subject for me I would greatly appreciate it.

Thank you,

Erick Johnson

curl and server logs follow....

$ curl -XPUT http://erick:foobar@127.0.0.40:5984/testing-compaction
{"ok":true}
$ curl -XPUT http://erick:foobar@127.0.0.40:5984/testing-compaction/_revs_limit 
-d "100"
{"ok":true}
$ curl http://erick:foobar@127.0.0.40:5984/testing-compaction/_revs_limit
100
$ curl -XPOST http://erick:foobar@127.0.0.40:5984/testing-compaction/_compact
{"ok":true}
$ curl http://erick:foobar@127.0.0.40:5984/testing-compaction/_revs_limit
1000
