* Geo: GEOADD implementation improved, replication fixedantirez2015-06-231-0/+1
| | | | | | | 1. We no longer use a fake client but just rewriting. 2. We group all the inserts into a single ZADD dispatch (big speed win). 3. As a side effect of the correct implementation, replication works. 4. The return value of the command is now correct.
* Geo: big refactoring of geo.c, zset.[ch] removed.antirez2015-06-231-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit simplifies the implementation in a few ways: 1. zsetScore implementation improved a bit and moved into t_zset.c where is now also used to implement the ZSCORE command. 2. Range extraction from the sorted set remains a separated implementation from the one in t_zset.c, but was hyper-specialized in order to avoid accumulating results into a list and remove the ones outside the radius. 3. A new type is introduced: geoArray, which can accumulate geoPoint structures in a vector with power of two expansion policy. This is useful since we have to call qsort() against it before returning the result to the user. 4. As a result of 1, 2, 3, the two files zset.c and zset.h are now removed, including the function to merge two lists (now handled with functions that can add elements to existing geoArray arrays) and the machinery used in order to pass zset results. 5. geoPoint structure simplified because of the general code structure simplification, so we no longer need to take references to objects. 6. Not counting the JSON removal the refactoring removes 200 lines of code for the same functionalities, with a simpler to read implementation. 7. GEORADIUS is now 2.5 times faster testing with 10k elements and a radius resulting in 124 elements returned. However this is mostly a side effect of the refactoring and simplification. More speed gains can be achieved by trying to optimize the code.
* Geo: zsetScore refactoringantirez2015-06-221-0/+1
| | | | Now used both in geo.c and t_zset to provide ZSCORE.
* [In-Progress] Add Geo CommandsMatt Stancliff2015-06-221-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | Current todo: - replace functions in zset.{c,h} with a new unified Redis zset access API. Once we get the zset interface fixed, we can squash relevant commits in this branch and have one nice commit to merge into unstable. This commit adds: - Geo commands - Tests; runnable with: ./runtest --single unit/geo - Geo helpers in deps/geohash-int/ - src/geo.{c,h} and src/geojson.{c,h} implementing geo commands - Updated build configurations to get everything working - TEMPORARY: src/zset.{c,h} implementing zset score and zset range reading without writing to client output buffers. - Modified linkage of one t_zset.c function for use in zset.c Conflicts: src/Makefile src/redis.c
* Replication: disconnect blocked clients when switching to slave role.antirez2015-03-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug as old as Redis and blocking operations. It's hard to trigger since only happens on instance role switch, but the results are quite bad since an inconsistency between master and slave is created. How to trigger the bug is a good description of the bug itself. 1. Client does "BLPOP mylist 0" in master. 2. Master is turned into slave, that replicates from New-Master. 3. Client does "LPUSH mylist foo" in New-Master. 4. New-Master propagates write to slave. 5. Slave receives the LPUSH, the blocked client get served. Now Master "mylist" key has "foo", Slave "mylist" key is empty. Highlights: * At step "2" above, the client remains attached, basically escaping any check performed during command dispatch: read only slave, in that case. * At step "5" the slave (that was the master), serves the blocked client consuming a list element, which is not consumed on the master side. This scenario is technically likely to happen during failovers, however since Redis Sentinel already disconnects clients using the CLIENT command when changing the role of the instance, the bug is avoided in Sentinel deployments. Closes #2473.
* CONFIG refactoring: configEnum abstraction.antirez2015-03-111-9/+9
| | | | | | Still many things to convert inside config.c in the next commits. Some const safety in String objects creation and addReply() family functions.
* Hash: HSTRLEN (was HVSTRLEN) improved.antirez2015-02-271-1/+1
| | | | | | | | | | | 1. HVSTRLEN -> HSTRLEN. It's unlikely one needs the length of the key, not clear how the API would work (by value does not make sense) and there will be better names anyway. 2. Default is to return 0 when field is missing. 3. Default is to return 0 when key is missing. 4. The implementation was slower than needed, and produced unnecessary COW. Related issue #2415.

| * Improve networking type correctnessMatt Stancliff2015-01-191-5/+5
| | | | | | | | | | | | | | | | read() and write() return ssize_t (signed long), not int. For other offsets, we can use the unsigned size_t type instead of a signed offset (since our replication offsets and buffer positions are never negative).
* | SPOP with count: initial fixes to the implementation.antirez2015-02-111-1/+3
| | | | | | | | | | | | | | | | | | | | | | Severan problems are addressed but still a few missing. Since replication of this command was more complex than others since it needs to replicate multiple SREM commands, an old API able to do this was reused (it was taken inside the implementation since it was pretty obvious soon or later that would be useful). The API was improved a bit so that now a command may opt-out for the standard command replication when the server.dirty counter is incremented, in order to "manually" replicate what it wants.
* | Handle redis-check-rdb as a standalone program.antirez2015-02-031-0/+1
| | | | | | | | | | | | | | | | | | | | This also makes it backward compatible in the usage, but for the command name. However the old command name was less obvious so it is worth to break it probably. With the new setup the program main can perform argument parsing and everything else useful for an RDB check regardless of the Redis server itself.
* | Convert check-dump to Redis check-rdb modeMatt Stancliff2015-01-281-0/+3
|/ | | | | | | | | | | | | redis-check-dump is now named redis-check-rdb and it runs as a mode of redis-server instead of an independent binary. You can now use 'redis-server redis.conf --check-rdb' to check the RDB defined in redis.conf. Using argument --check-rdb checks the RDB and exits. We could potentially also allow the server to continue starting if the RDB check succeeds. This change also enables us to use RDB checking programatically from inside Redis for certain failure conditions.
* Cluster: clusterMsgDataGossip structure, explict padding + minor stuff.antirez2015-01-131-1/+1
| | | | | | | | | | Also explicitly set version to 0, add a protocol version define, improve comments in the gossip structure. Note that the structure layout is the same after the change, we are just making the padding explicit with an additional not used 16 bits field. So this commit is still able to talk with the previous versions of cluster nodes.
* Supervise redis processes only if configuredMatt Stancliff2015-01-091-1/+8
| | | | | | | | | | | Adds configuration option 'supervised [no | upstart | systemd | auto]' Also removed 'bzero' from the previous implementation because it's 2015. (We could actually statically initialize those structs, but clang throws an invalid warning when we try, so it looks bad even though it isn't bad.) Fixes #2264

* Config: Add quicklist, remove old list optionsMatt Stancliff2015-01-021-4/+8
| | | | | | | | | | | | | This removes: - list-max-ziplist-entries - list-max-ziplist-value This adds: - list-max-ziplist-size - list-compress-depth Also updates config file with new sections and updates tests to use quicklist settings instead of old list settings.
* Add quicklist implementationMatt Stancliff2015-01-021-6/+6
| | | | | | | | This replaces individual ziplist vs. linkedlist representations for Redis list operations. Big thanks for all the reviews and feedback from everybody in https://github.com/antirez/redis/pull/2143
* Allow all code tests to run using Redis argsMatt Stancliff2014-12-231-0/+6
| | | | | | | | | | | | | | | | | | | | | Previously, many files had individual main() functions for testing, but each required being compiled with their own testing flags. That gets difficult when you have 8 different flags you need to set just to run all tests (plus, some test files required other files to be compiled aaginst them, and it seems some didn't build at all without including the rest of Redis). Now all individual test main() funcions are renamed to a test function for the file itself and one global REDIS_TEST define enables testing across the entire codebase. Tests can now be run with: - `./redis-server test <test>` e.g. ./redis-server test ziplist If REDIS_TEST is not defined, then no tests get included and no tests are included in the final redis-server binary.

| | | | | | | | | | | | | | | | | | spopCommand() now runs spopWithCountCommand() in case the <count> param is found. Added intsetRandomMembers() to Intset: Copies N random members from the set into inputted 'values' array. Uses either the Knuth or Floyd sample algos depending on ratio count/size. Added setTypeRandomElements() to SET type: Returns a number of random elements from a non empty set. This is a version of setTypeRandomElement() that is modified in order to return multiple entries, using dictGetRandomKeys() and intsetRandomMembers(). Added tests for SPOP with <count>: unit/type/set, unit/scripting, integration/aof -- Cleaned up code a bit to match with required Redis coding style
* | Add cached total system memory to INFO outputMatt Stancliff2014-12-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no standard cross-platform way of obtaining system memory info, but I found a useful function convering all common platforms. I removed support for uncommon Redis platforms (windows, AIX) and left others intact. For more info, see: http://nadeausoftware.com/articles/2012/09/c_c_tip_how_get_physical_memory_size_system The system memory info is cached on startup, but some systems may be able to change the amount of memory visible to Redis at runtime if Redis is deployed in a VM or container. Also see #1820

| * Support daemon supervision by upstart or systemdPierre-Yves Ritschard2014-11-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both upstart and systemd provide a way for daemons to be supervised, as well as a mechanism for them to signal their readyness status. This patch provides compatibility with this functionality while not interfering with other methods. With this, it will be possible to use `expect stop` with upstart and `Type=notify` with systemd. A more detailed explanation of the mechanism can be found here: http://spootnik.org/entries/2014/11/09_pid-tracking-in-modern-init-systems.html

* | Diskless SYNC: fix RDB EOF detection.antirez2014-11-111-0/+1
|/ | | | | | | | | | | | | | | | | | | RDB EOF detection was relying on the final part of the RDB transfer to be a magic 40 bytes EOF marker. However as the slave is put online immediately, and because of sockets timeouts, the replication stream is actually contiguous with the RDB file. This means that to detect the EOF correctly we should either: 1) Scan all the stream searching for the mark. Sucks CPU-wise. 2) Start to send the replication stream only after an acknowledge. 3) Implement a proper chunked encoding. For now solution "2" was picked, so the master does not start to send ASAP the stream of commands in the case of diskless replication. We wait for the first REPLCONF ACK command from the slave, that certifies us that the slave correctly loaded the RDB file and is ready to get more data.
