Fix regression in reconnect logic.
Very much need automated tests for reconnection and queue logic.
Many contributed fixes. Thanks everybody.
- [GH-127] - properly re-initialize parser on reconnect
- [GH-136] - handle passing undefined as callback (Ian Babrou)
- [GH-139] - properly handle exceptions thrown in pub/sub event handlers (Felix Geisendörfer)
- [GH-141] - detect closing state on stream error (Felix Geisendörfer)
- [GH-142] - re-select database on reconnection (Jean-Hugues Pinson)
- [GH-146] - add sort example (Maksim Lin)
Some more goodies:
- Fix bugs with node 0.6
- Performance improvements
- New version of
multi_bench.jsthat tests more realistic scenarios - [GH-140] - support optional callback for subscribe commands
- Properly flush and error out command queue when connection fails
- Initial work on reconnection thresholds
(accidentally skipped v0.6.6)
Fix and test for [GH-123]
Passing an Array as as the last argument should expand as users expect. The old behavior was to coerce the arguments into Strings, which did surprising things with Arrays.
Contributed changes:
- Support SlowBuffers (Umair Siddique)
- Add Multi to exports (Louis-Philippe Perron)
- Fix for drain event calculation (Vladimir Dronnikov)
Thanks!
Fix bug with optional callbacks for hmset.
Bugs fixed:
- authentication retry while server is loading db (danmaz74) [GH-101]
- command arguments processing issue with arrays
New features:
- Auto update of new commands from redis.io (Dave Hoover)
- Performance improvements and backpressure controls.
- Commands now return the true/false value from the underlying socket write(s).
- Implement command_queue high water and low water for more better control of queueing.
See examples/backpressure_drain.js for more information.
Add support and tests for Redis scripting through EXEC command.
Bug fix for monitor mode. (forddg)
Auto update of new commands from redis.io (Dave Hoover)
Lots of bugs fixed.
- connection error did not properly trigger reconnection logic [GH-85]
- client.hmget(key, [val1, val2]) was not expanding properly [GH-66]
- client.quit() while in pub/sub mode would throw an error [GH-87]
- client.multi(['hmset', 'key', {foo: 'bar'}]) fails [GH-92]
- unsubscribe before subscribe would make things very confused [GH-88]
- Add BRPOPLPUSH [GH-79]
Added DISCARD
I originally didn't think DISCARD would do anything here because of the clever MULTI interface, but somebody pointed out to me that DISCARD can be used to flush the WATCH set.
Added HVALS
Fix bug with empty Array arguments - Andy Ray
Add MONITOR command and special monitor command reply parsing.
Add magical auth command.
Authentication is now remembered by the client and will be automatically sent to the server on every connection, including any reconnections.
Fix bug in ready check with return_buffers set to true.
Thanks to Dean Mao and Austin Chau.
Add probe for server readiness.
When a Redis server starts up, it might take a while to load the dataset into memory. During this time, the server will accept connections, but will return errors for all non-INFO commands. Now node_redis will send an INFO command whenever it connects to a server. If the info command indicates that the server is not ready, the client will keep trying until the server is ready. Once it is ready, the client will emit a "ready" event as well as the "connect" event. The client will queue up all commands sent before the server is ready, just like it did before. When the server is ready, all offline/non-ready commands will be replayed. This should be backward compatible with previous versions.
To disable this ready check behavior, set options.no_ready_check when creating the client.
As a side effect of this change, the key/val params from the info command are available as
client.server_options. Further, the version string is decomposed into individual elements
in client.server_options.versions.
Fix excess memory consumption from Queue backing store.
Thanks to Gustaf Sjöberg.
Fix multi/exec error reply callback logic.
Thanks to Stella Laurenzo.
Fix bug where unhandled error replies confuse the parser.
Fix bug where subscribe commands would not handle redis-server startup error properly.
Some bug fixes:
- An important bug fix in reconnection logic. Previously, reply callbacks would be invoked twice after a reconnect.
- Changed error callback argument to be an actual Error object.
New feature:
- Add friendly syntax for HMSET using an object.
Remove warning about missing hiredis. You probably do want it though.
Support for multiple response parsers and hiredis C library from Pieter Noordhuis. Return Strings instead of Buffers by default. Empty nested mb reply bug fix.
Fix parser bug on failed EXECs.
Fix for null MULTI response when WATCH condition fails.
Add "drain" and "idle" events.
Add all known Redis commands from Redis master, even ones that are coming in 2.2 and beyond.
Send a friendlier "error" event message on stream errors like connection refused / reset.
A few bug fixes.
- Fixed bug with
nilmulti-bulk reply lengths that showed up withBLPOPtimeouts. - Only emit
endonce when connection goes away. - Fixed bug in
test.jswhere driver finished before all tests completed.
