-BEFORE REDIS 1.0.0-rc1
-
- * Warning if using default config, with hint about 'redis-server redis.conf'
- * Add number of keys for every DB in INFO
- * maxmemory support
- * maxclients support
- * Resize the expires and Sets hash tables if needed as well? For Sets the right moment to check for this is probably in SREM
- * What happens if the saving child gets killed or segfaults instead of ending normally? Handle this.
- * Make sinterstore / unionstore / sdiffstore returning the cardinality of the resulting set.
- * check 'server.dirty' everywere
- * Shutdown must kill other background savings before to start saving. Otherwise the DB can get replaced by the child that rename(2) after the parent for some reason. Child should trap the signal and remove the temp file name.
- * Objects sharing configuration, add the directive `objectsharingpool <size>`
- * Make sure to convert all the fstat() calls to 64bit versions.
- * Cover most of the source code with test-redis.tcl
-
-AFTER 1.0 stable release
-
- * Consistent hashing implemented in all the client libraries having an user base
- * SORT: Don't copy the list into a vector when BY argument is constant.
- * SORT ... STORE keyname. Instead to return the SORTed data set it into key.
- * Profiling and optimization in order to limit the CPU usage at minimum
- * Write the hash table size of every db in the dump, so that Redis can resize the hash table just one time when loading a big DB.
- * Elapsed time in logs for SAVE when saving is going to take more than 2 seconds
- * LOCK / TRYLOCK / UNLOCK as described many times in the google group
- * Replication automated tests
-
-FUTURE HINTS
-
-- In memory compression: if in-memory values compression will be implemented, make sure to implement this so that addReply() is able to handle compressed objects, just creating an uncompressed version on the fly and adding this to the output queue instead of the original one. When insetad we need to look at the object string value (SORT BY for example), call a function that will turn the object into an uncompresed one.
+Redis TODO
+----------
+
+WARNING: are you a possible Redis contributor?
+ Before implementing what is listed what is listed in this file
+ please drop a message in the Redis google group or chat with
+ antirez or pietern on irc.freenode.org #redis to check if the work
+ is already in progress and if the feature is still interesting for
+ us, and *how* exactly this can be implemented to have good changes
+ of a merge. Otherwise it is probably wasted work! Thank you
+
+DISKSTORE TODO
+==============
+
+* Check that 00/00 and ff/ff exist at startup, otherwise exit with error.
+* Implement sync flush option, where data is written synchronously on disk when a command is executed.
+* Implement MULTI/EXEC as transaction abstract API to diskstore.c, with transaction_start, transaction_end, and a journal to recover.
+* Stop BGSAVE thread on shutdown and any other condition where the child is killed during normal bgsave.
+* Use a mutex to log on the file, so that we don't get overlapping messages, or even better make sure to use a single write against it.
+* Fix RANDOMKEY to really do something interesting
+* Fix DBSIZE to really do something interesting
+* Add a DEBUG command to check if an entry is or not in memory currently
+* Prevent io jobs from running while there is a BGSAVE thread.
+
+REPLICATION
+===========
+
+* PING between master and slave from time to time, so we can subject the
+master-slave link to timeout, and detect when the connection is gone even
+if the socket is still up.
+
+OPTIMIZATIONS
+=============
+
+* SORT: Don't copy the list into a vector when BY argument is constant.
+* Write the hash table size of every db in the dump, so that Redis can resize the hash table just one time when loading a big DB.
+* Read-only mode for slaves.
+
+KNOWN BUGS
+==========
+
+* What happens in the following scenario:
+ 1) We are reading an AOF file.
+ 2) SETEX FOO 5 BAR
+ 3) APPEND FOO ZAP
+ What happens if between 1 and 2 for some reason (system under huge load
+ or alike) too many time passes? We should prevent expires while the
+ AOF is loading.
