Add more information to the view info objects. 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
View refactoring and addition of raw collationoption. Significant performance improvements in view indexer.
fix speling, thanks Jason
various bugfixes and improvements for view compaction 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
Deterministic revids, MD5 checking of documents, added tracking of rev when an attachment is edited to allow attachment level replication.
checkpoint long-running view updates 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.
wheeeeeeee
trimmed trailing whitespace
Name view index files by their function hashes for no downtime deploys. 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.
Test and fix for infinite loops in view_servers, fix for crashed OS processes causing leaked erlang processes and fix for view server crashing when view group process terminates.
Merging new tail append storage into trunk. Upgrades are automatic, once opened by this version old versions of CouchDB will not be able to open the files. As a precaution, you should back-up your production databases before upgrading.
reduce_limit error is thrown when the reduce function output is not small enough compared to the input. Errors can be switched off using the config API.
Fixes for leaked file handles, with test.
added compaction for view indexes. See COUCHDB-92 No tests or Futon interface for this feature yet.
Added options member to design docs. Currently the only option is include_designs (views can now run over design docs as well if they need to), the default is false, which is the current behavior. Thanks davisp for the original patch. Closes COUCHDB-156
Added task status checking, to help debug the progress of long running tasks, like view indexing and compaction.
Added support so clients can detect if a server has potentially lost commits after multiple updates, like during bulk imports and so the replicator can detect lost commits on remote replications.
Fixed views to not commit index headers if they are ahead of what has been fully committed to the database. Also, the index headers are now committed async, improving response times updating views.
Rename _temp_views to _slow_views. Any clients who were using temp views are encouraged not to use slow views, and instead transition to design documents (or running the views on the client).
fix for crash of couch_server when database non-existant
move couchdb to tlp
modifications to view server to keep the file descriptor open for the life of the view group.
view group state gen_server. thanks damien and davisp.
