* 2.4.9 (in development)
* Removed socket retry logic in Connection. This is the responsbility of
the caller to determine if the command is safe and can be retried. Thanks
David Wolver.
* 2.4.8
* Imported with_statement from __future__ for Python 2.5 compatability.
* 2.4.7
* Fixed a bug where some connections were not getting released back to the
connection pool after pipeline execution.
* Pipelines can now be used as context managers. This is the preferred way
of use to ensure that connections get cleaned up properly. Thanks
David Wolever.
* Added a convenience method called transaction() on the base Redis class.
This method eliminates much of the boilerplate used when using pipelines
to watch Redis keys. See the documentation for details on usage.
* 2.4.6
* Variadic arguments for SADD, SREM, ZREN, HDEL, LPUSH, and RPUSH. Thanks
Raphaël Vinot.
* (CRITICAL) Fixed an error in the Hiredis parser that occasionally caused
the socket connection to become corrupted and unusable. This became
noticeable once connection pools started to be used.
* ZRANGE, ZREVRANGE, ZRANGEBYSCORE, and ZREVRANGEBYSCORE now take an
additional optional argument, score_cast_func, which is a callable used
to cast the score value in the return type. The default is float.
* Removed the PUBLISH method from the PubSub class. Connections that are
[P]SUBSCRIBEd cannot issue PUBLISH commands, so it doesn't make sense
to have it here.
* Pipelines now contain WATCH and UNWATCH. Calling WATCH or UNWATCH from
the base client class will result in a deprecation warning. After
WATCHing one or more keys, the pipeline will be placed in immediate
execution mode until UNWATCH or MULTI are called. Refer to the new
pipeline docs in the README for more information. Thanks to David Wolever
and Randall Leeds for greatly helping with this.
* 2.4.5
* The PythonParser now works better when reading zero length strings.
* 2.4.4
* Fixed a typo introduced in 2.4.3
* 2.4.3
* Fixed a bug in the UnixDomainSocketConnection caused when trying to
form an error message after a socket error.
* 2.4.2
* Fixed a bug in pipeline that caused an exception while trying to
reconnect after a connection timeout.
* 2.4.1
* Fixed a bug in the PythonParser if disconnect is called before connect.
* 2.4.0
* WARNING: 2.4 contains several backwards incompatible changes.
* Completely refactored Connection objects. Moved much of the Redis
protocol packing for requests here, and eliminated the nasty dependencies
it had on the client to do AUTH and SELECT commands on connect.
* Connection objects now have a parser attribute. Parsers are responsible
for reading data Redis sends. Two parsers ship with redis-py: a
PythonParser and the HiRedis parser. redis-py will automatically use the
HiRedis parser if you have the Python hiredis module installed, otherwise
it will fall back to the PythonParser. You can force or the other, or even
an external one by passing the `parser_class` argument to ConnectionPool.
* Added a UnixDomainSocketConnection for users wanting to talk to the Redis
instance running on a local machine only. You can use this connection
by passing it to the `connection_class` argument of the ConnectionPool.
* Connections no longer derive from threading.local. See threading.local
note below.
* ConnectionPool has been comletely refactored. The ConnectionPool now
maintains a list of connections. The redis-py client only hangs on to
a ConnectionPool instance, calling get_connection() anytime it needs to
send a command. When get_connection() is called, the command name and
any keys involved in the command are passed as arguments. Subclasses of
ConnectionPool could use this information to identify the shard the keys
belong to and return a connection to it. ConnectionPool also implements
disconnect() to force all connections in the pool to disconnect from
the Redis server.
* redis-py no longer support the SELECT command. You can still connect to
a specific database by specifing it when instantiating a client instance
or by creating a connection pool. If you need to talk to multiplate
databases within your application, you should use a separate client
instance for each database you want to talk to.
* Completely refactored Publish/Subscribe support. The subscribe and listen
commands are no longer available on the redis-py Client class. Instead,
the `pubsub` method returns an instance of the PubSub class which contains
all publish/subscribe support. Note, you can still PUBLISH from the
redis-py client class if you desire.
* Removed support for all previously deprecated commands or options.
* redis-py no longer uses threading.local in any way. Since the Client
class no longer holds on to a connection, it's no longer needed. You can
now pass client instances between threads, and commands run on those
threads will retrieve an available connection from the pool, use it and
release it. It should now be trivial to use redis-py with eventlet or
greenlet.
* ZADD now accepts pairs of value=score keyword arguements. This should help
resolve the long standing #72. The older value and score arguements have
been deprecated in favor of the keyword argument style.
* Client instances now get their own copy of RESPONSE_CALLBACKS. The new
set_response_callback method adds a user defined callback to the instance.
* Support Jython, fixing #97. Thanks to Adam Vandenberg for the patch.
* Using __getitem__ now properly raises a KeyError when the key is not
found. Thanks Ionuț Arțăriși for the patch.
* Newer Redis versions return a LOADING message for some commands while
the database is loading from disk during server start. This could cause
problems with SELECT. We now force a socket disconnection prior to
raising a ResponseError so subsuquent connections have to reconnect and
re-select the appropriate database. Thanks to Benjamin Anderson for
finding this and fixing.
* 2.2.4
* WARNING: Potential backwards incompatible change - Changed order of
parameters of ZREVRANGEBYSCORE to match those of the actual Redis command.
This is only backwards-incompatible if you were passing max and min via
keyword args. If passing by normal args, nothing in user code should have
to change. Thanks Stéphane Angel for the fix.
* Fixed INFO to properly parse the Redis data correctly for both 2.2.x and
2.3+. Thanks Stéphane Angel for the fix.
* Lock objects now store their timeout value as a float. This allows floats
to be used as timeout values. No changes to existing code required.
* WATCH now supports multiple keys. Thanks Rich Schumacher.
* Broke out some code that was Python 2.4 incompatible. redis-py should
now be useable on 2.4, but this hasn't actually been tested. Thanks
Dan Colish for the patch.
* Optimized some code using izip and islice. Should have a pretty good
speed up on larger data sets. Thanks Dan Colish.
* Better error handling when submitting an empty mapping to HMSET. Thanks
Dan Colish.
* Subscription status is now reset after every (re)connection.
* 2.2.3
* Added support for Hiredis. To use, simply "pip install hiredis" or
"easy_install hiredis". Thanks for Pieter Noordhuis for the hiredis-py
bindings and the patch to redis-py.
* The connection class is chosen based on whether hiredis is installed
or not. To force the use of the PythonConnection, simply create
your own ConnectionPool instance with the connection_class argument
assigned to to PythonConnection class.
* Added missing command ZREVRANGEBYSCORE. Thanks Jay Baird for the patch.
* The INFO command should be parsed correctly on 2.2.x server versions
and is backwards compatible with older versions. Thanks Brett Hoerner.
* 2.2.2
* Fixed a bug in ZREVRANK where retriving the rank of a value not in
the zset would raise an error.
* Fixed a bug in Connection.send where the errno import was getting
overwritten by a local variable.
* Fixed a bug in SLAVEOF when promoting an existing slave to a master.
* Reverted change of download URL back to redis-VERSION.tar.gz. 2.2.1's
change of this actually broke Pypi for Pip installs. Sorry!
* 2.2.1
* Changed archive name to redis-py-VERSION.tar.gz to not conflict
with the Redis server archive.
* 2.2.0
* Implemented SLAVEOF
* Implemented CONFIG as config_get and config_set
* Implemented GETBIT/SETBIT
* Implemented BRPOPLPUSH
* Implemented STRLEN
* Implemented PERSIST
* Implemented SETRANGE
