2009-05-16replicator memory management and buffer flush calculation updatesAdam Kocoloski
* new should_flush fun considers ndocs, nattachments, memory in making decision * memory utilized by attachment receivers is accounted for * download attachments using standalone connections instead of conn pool. This prevents a document request from getting stuck behind a huge attachment, which would prevent us from triggering a buffer flush in time. We also consider the memory utilization of the standalone ibrowse connection in should_flush git-svn-id: https://svn.apache.org/repos/asf/couchdb/trunk@775507 13f79535-47bb-0310-9956-ffa450edef68

update seq numbers and pointers to bodies on disk, for use in the _changes api. This is a new file version, but the code can continue to serve the old 0.9 version without problems, though certain features in the _changes api will not be able to work. Upgrade to new file version (from 1 to 2) by compacting the file. Also fixed bugs with how the stats api tracks open databases. git-svn-id: https://svn.apache.org/repos/asf/couchdb/trunk@772406 13f79535-47bb-0310-9956-ffa450edef68

2009-03-16Fix for occasional replication failure where replication would complete ↵Damien F. Katz
before before the caller had a chance to request the results.

2009-03-08beefier fault tolerance in the replicatorAdam Kocoloski
- trap exits (enumerator and attachment streamers are linked) - retry by respawning enumerator with last known good source seq - checkpoint replication record on every flush of document buffer - reformat nicer error messages to listeners if we need to exit git-svn-id: https://svn.apache.org/repos/asf/couchdb/trunk@751491 13f79535-47bb-0310-9956-ffa450edef68
