View info is available at the URL: http://127.0.0.1:5984/db_name/_design/ddocid/_info New fields include: updater_running [true|false] : Whether the view is being built waiting_commit [true|false] : Whether this view is a head of db commits waiting_clients [integer] : How many clients are waiting on this view update_seq [integer] : The update sequence that has been indexed purge_seq [integer] : The purge sequence that has been processed Other fields for reference: signature [string] : The md5 signature of the design document's functions language [string] : The language of the design document disk_size [integer] : Number of bytes the view file occupies on disk compact_running [boolean] : Whether the view is currently being compacted git-svn-id: https://svn.apache.org/repos/asf/couchdb/trunk@824970 13f79535-47bb-0310-9956-ffa450edef68

2009-07-22various bugfixes and improvements for view compactionAdam Kocoloski
View compaction was broken after the switch to signature-based index files, but we don't have tests for it yet so we didn't notice. I also committed a few changes that should make compaction faster and more robust: * commit the header immediately after compaction finishes. We used to wait 1 seconds, but if the server restarted in that second the index would be reset. * unlink from old index file at the end. Prevents process crashes that could couch_view (and with the delayed commit would sometimes cause index resets). * don't wait for running view updates to finish before replacing old view index file. If an update is running, restart it and point it to the new view group. This alleviates the situation where the view compaction goes into a busy wait, printing "still behind main file" 1000s of times to the log, and generally makes compaction finish more quickly. * better logging git-svn-id: https://svn.apache.org/repos/asf/couchdb/trunk@796805 13f79535-47bb-0310-9956-ffa450edef68

2009-07-16checkpoint long-running view updatesAdam Kocoloski
Improves stale=ok view queries, which will now see gradually updating indexes. Also reduces the consequences of an updater crash because we can restart from the latest checkpoint. git-svn-id: https://svn.apache.org/repos/asf/couchdb/trunk@794843 13f79535-47bb-0310-9956-ffa450edef68

2009-07-04Name view index files by their function hashes for no downtime deploys. ↵John Christopher Anderson
Closes COUCHDB-218 Adds ability to switch view indexes on the fly by building the index from a "staging" design doc, and then COPYing the staging doc to the production doc's id. Since indexes are referenced by view definition, the new version of the production design doc will point immediately to the index files already built in staging. Please use and give feedback. git-svn-id: https://svn.apache.org/repos/asf/couchdb/trunk@791140 13f79535-47bb-0310-9956-ffa450edef68
