-BEFORE REDIS 1.0.0-rc1
+Pre 1.1 todo

 
 

- * Replication status in INFO command. role: (master|slave) slaveof: <host:port>, slavestatus: (disconnected|ok)
- * 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.
- * check 'server.dirty' everywere. Make it proprotional to the number of objects modified.
- * 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
+* For now only the last argument gets integer encoded, so make sure that: 1) every multi bulk commands implemented will have the last arg that is indeed a value, and not used otherwise. 2) to explicitly call the function to encode the object in MSET and other commands where there are multiple "values".

+* Expiring algorithm should be adaptive, if there are a lot of keys with an expire set and many of this happen to be already expired it should be, proportionally, more aggressive.
+ * Add a command to inspect the currently selected DB index

  * 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.

+ * some kind of sorted type, example:
+        ZADD mykey foo 100
+        ZADD mykey bar 50
+   ZRANGE mykey 0 1 => bar foo
+   This is able to take elements sorted because a binary tree is used to store
+   the elements by 'score', with the actual value being the key. On the other
+   side the type also takes an hash table with key->score mapping, so that when
+   there is an update we lookup the current score and can traverse the tree.
+ * BITMAP / BYTEARRAY type?
+ * LRANGE 4 0 should return the same elements as LRANGE 0 4 but in reverse order (only if we get enough motivated requests about it)
+ * zmalloc() should avoid to add a private header for archs where there is some other kind of libc-specific way to get the size of a malloced block.
