-BEFORE REDIS 1.0.0-rc1
-
-- Contrib dir with RHL for Centos and other contributions like init scripts
-- Update the FAQ with max number of keys in a DB and the overcommit thing
-- Add number of keys for every DB in INFO
-- maxmemory support in config file.
-- Resize the expires hash tables if needed as well
-- TTL command that returns -1 if a key is not volatile otherwise the time to live of a volatile key.
-- Remove max number of args limit
-- 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.
-- maxclients directive
-- 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.
-- Document replication
-- Objects sharing configuration, add the directive "objectsharingpool <size>"
-- Make sure to convert all the fstat() calls to 64bit versions.
-- SINTERCOUNT, SUNIONCOUNT, SDIFFCOUNT
-
-AFTER 1.0 stable release
-
-- Use partial qsort for SORT + LIMIT. Don't copy the list into a vector when BY argument is constant.
-- Locking primitives
-- MDEL (or vararg DEL)
-- 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
-- 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
+==============
+
+* Fix FLUSHALL/FLUSHDB: the queue of pending reads/writes should be handled.
+* 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.
+* 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
+
+* dscache.c near 236, kobj = createStringObject... we could use static obj.
+
+APPEND ONLY FILE
+================
+
+* in AOF rewirte use HMSET to rewrite small hashes instead of multiple calls
+ to HSET.
+
+OPTIMIZATIONS
+=============
+
+* Avoid COW due to incrementing the dict iterators counter.
+* 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.
+* Redis big lists as linked lists of small ziplists?
+ Possibly a simple heuristic that join near nodes when some node gets smaller than the low_level, and split it into two if gets bigger than high_level.
+
+REPORTING
+=========
+
+* Better INFO output with sections.
+
+RANDOM
+======
+
+* Clients should be closed as far as the output buffer list is bigger than a given number of elements (configurable in redis.conf)
+* Should the redis default configuration, and the default redis.conf, just bind 127.0.0.1?
+
+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.
