2009-09-02fix continuous replication occurring after identical normal oneAdam Kocoloski
Both forms of replication had the same child ID in the replication supervisor. As a result, a continuous replication triggered after an otherwise-identical normal replication would "forget" that it was continuous. The tricky part about this patch is that it lets a normal and a continuous replication with the same source and target execute simultaneously. That's inefficient, but other solutions are convoluted or give surprising results to the client. git-svn-id: https://svn.apache.org/repos/asf/couchdb/trunk@810358 13f79535-47bb-0310-9956-ffa450edef68

2009-08-15better failure modes in replication. See COUCHDB-193, COUCHDB-416Adam Kocoloski
If you try to replicate a DB to itself, the replication will proceed, but no checkpoints will be saved, and the logs will say "checkpoint failure: conflict (are you replicating to yourself?)" If you try to specify a non-existent DB as source or target, replication will fail immediately with a 404. The response body will indicate which DB could not be opened. git-svn-id: https://svn.apache.org/repos/asf/couchdb/trunk@804436 13f79535-47bb-0310-9956-ffa450edef68

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
