antirez aa96122d96 Mask SIGALRM everything but in the main thread. 
This is required to ensure that the signal will be delivered to the main
thread when the watchdog timer expires.
 2012-03-27 13:48:57 +02:00
antirez a354da9acd Correctly set the SIGARLM timer for the software watchdog. 2012-03-27 12:11:37 +02:00

antirez a323870450 SIGSEGV handler refactored so that we can reuse stack trace and current client logging functionalities in other contexts. 2012-03-27 10:40:07 +02:00
antirez ca09ad4d64 CONFIG RESETSTAT resets two more fields. 2012-03-25 11:43:19 +02:00
antirez c1d01b3c57 New INFO field aof_delayed_fsync introduced. 
This new field counts all the times Redis is configured with AOF enabled and
fsync policy 'everysec', but the previous fsync performed by the
background thread was not able to complete within two seconds, forcing
Redis to perform a write against the AOF file while the fsync is still
in progress (likely a blocking operation).

antirez 1f6146df0c Result of INCRBYFLOAT and HINCRBYFLOAT should never be in exponential form, and also should never contain trailing zeroes. This is not possible with vanilla printf() format specifiers, so we alter the output. 2012-03-22 18:17:05 +01:00
antirez b22eab8faf Correctly create shared.oomerr as an sds string. 2012-03-21 12:11:07 +01:00
antirez 7dcdd281f5 DEBUG should not be flagged as w otherwise we can not call DEBUG DIGEST and other commands against read only slaves. 2012-03-20 17:53:47 +01:00
antirez f3fd419fc9 Support for read-only slaves. Semantical fixes. 
This commit introduces support for read only slaves via redis.conf and CONFIG GET/SET commands. Also various semantical fixes are implemented here:

1) MULTI/EXEC with only read commands now work where the server is into a state where writes (or commands increasing memory usage) are not allowed. Before this patch everything inside a transaction would fail in this conditions.

2) Scripts just calling read-only commands will work against read only
slaves, when the server is out of memory, or when persistence is into an
error condition. Before the patch EVAL always failed in this condition.

antirez a5801142a4 Fixed typo. 2012-03-18 17:27:56 +01:00
antirez 1a197a3c1a Number of iteration of --test-memory is now 300 (several minutes per gigabyte). Memtest86 and Memtester links are also displayed while running the test. 2012-03-18 17:25:00 +01:00
antirez 525be599a8 On crash suggest to give --test-memory a try. 2012-03-18 11:35:35 +01:00

antirez c5166e3fc5 First implementation of --test-memory. Still a work in progress. 2012-03-16 17:17:39 +01:00
antirez c9d3dda29c Fix for issue #391. 
Use a simple protocol between clientsCron() and helper functions to
understand if the client is still valind and clientsCron() should
continue processing or if the client was freed and we should continue
with the next one.

huangz1990 9448ddb0c6 fix typo 2012-03-15 14:27:14 +08:00
antirez ae22bf1ef6 Reclaim space from the client querybuf if needed. 2012-03-14 15:32:30 +01:00
antirez 739803c064 sds.c: sdsAllocSize() function added. 2012-03-14 14:58:26 +01:00
antirez 9555f8f21b sds.c new function sdsRemoveFreeSpace(). 
The new function is used in order to resize the string allocation so
that only the minimal allocation possible is used, removing all the free
space at the end of the string normally used to improve efficiency of
concatenation operations.
 2012-03-14 10:13:23 +01:00
antirez 529bde82ec Call all the helper functions needed by clientsCron() as clientsCronSomething() for clarity. 2012-03-14 09:56:22 +01:00

antirez 573373802e c->bufpos initialization moved for aesthetics. 2012-03-13 12:59:27 +01:00
antirez c3e7441dad RDB hashes loading, fixed another bug in the loading of HT-encoded hashes: when the hash entry is too big for ziplist, add the field, then convert. The code used to break before the new entry was inserted, resulting into missing fields in the loaded Hash object. 2012-03-13 11:00:18 +01:00
antirez c3c856228d RDB hashes loading fixed removing the assertion that failed every time an HT-encoded hash was loaded. 2012-03-13 09:49:11 +01:00
antirez 64b4c33c0b Build dependencies updated. 2012-03-10 12:40:03 +01:00
antirez f12d0224f3 RDB4 support in redis-check-dump. 2012-03-10 12:38:42 +01:00
antirez c7d7d0a80f RDB version is no 4, because small hashes are now encoded as ziplists, so older versions of Redis will not understand this format. 2012-03-10 12:35:31 +01:00
antirez 753bb3dcbd More vertical space saved. 2012-03-10 11:19:17 +01:00
antirez c0caa1cf54 Minor code aesthetic change to use Redis code base style rule of saving vertical space when possible. 2012-03-10 11:09:43 +01:00
antirez d22248ae99 Removed handling of deprecated hash-max-zipmap-entries nad hash-map-zipmap-value. Pieter is too good with users ;). Better to have them switch to a saner configuration ASAP after the 2.6 upgrade. 2012-03-10 10:41:39 +01:00
antirez addc032756 Added a top-function comment to rioWriteHashIteratorCursor() to better specify what the function does. Not immediately clear from the name. 2012-03-10 10:36:51 +01:00
antirez 8562798308 Merge conflicts resolved. 2012-03-09 22:07:45 +01:00
antirez 250e7f6908 Instantaneous ops/sec figure in INFO output. 2012-03-08 16:15:37 +01:00
antirez 0823e48fb9 Support for all the redis.conf fields in CONFIG GET. config.c refactored a bit. 2012-03-08 12:14:23 +01:00
antirez 91d664d6ce run_id added to INFO output. 
The Run ID is a field that identifies a single execution of the Redis
server. It can be useful for many purposes as it makes easy to detect if
the instance we are talking about is the same, or if it is a different
one or was rebooted. An application of run_id will be in the partial
synchronization of replication, where a slave may request a partial sync
from a given offset only if it is talking with the same master. Another
application is in failover and monitoring scripts.
 2012-03-08 10:13:36 +01:00
antirez 44f508f1a8 clusterGetRandomName() generalized into getRandomHexChars() so that we can use it for the run_id field as well. 2012-03-08 10:08:44 +01:00
antirez 4d3bbf3590 By default Redis refuses writes with an error if the latest BGSAVE failed (and at least one save point is configured). However people having good monitoring systems may prefer a server that continues to work, since they are notified that there are problems by their monitoring systems. This commit implements the ability to turn the feature on or off via redis.conf and CONFIG SET. 2012-03-07 18:02:26 +01:00
antirez c25e7eafef Refuse writes if can't persist on disk. 
Redis now refuses accepting write queries if RDB persistence is
configured, but RDB snapshots can't be generated for some reason.
The status of the latest background save operation is now exposed
in the INFO output as well. This fixes issue #90.
 2012-03-07 13:05:53 +01:00
antirez e31b615e62 Better MONITOR output, now includes client ip:port or the lua string if the command was executed by the scripting engine. 2012-03-07 12:12:15 +01:00
antirez 7b845b6228 anetPeerToString() automatically populates ip/port with something that may be provided to the user as output in case of errors. 2012-03-07 11:30:30 +01:00
antirez 9494f1f15b TIME command. 2012-03-07 10:38:01 +01:00
antirez 60893c6cc6 redis-cli: CSV output added, used for the --slave mode. 2012-02-29 17:43:06 +01:00
antirez b8283ab218 Initial implementation of redis-cli --slave support. 2012-02-29 17:10:21 +01:00

antirez c1db214eeb Better implementation for BRPOP/BLPOP in the non blocking case. 2012-02-29 14:41:57 +01:00
antirez cd8bdea31b lpush arguments vector rewrite modified for more speed and to memory leak removal. 2012-02-29 13:38:30 +01:00
antirez b67feecacd Version bumped to 2.9.5 2012-02-29 00:54:52 +01:00
antirez 78d6a22dc3 Better system for additional commands replication. 
The new code uses a more generic data structure to describe redis operations.
The new design allows for multiple alsoPropagate() calls within the scope of a
single command, that is useful in different contexts. For instance there
when there are multiple clients doing BRPOPLPUSH against the same list,
and a variadic LPUSH is performed against this list, the blocked clients
will both be served, and we should correctly replicate multiple LPUSH
commands after the replication of the current command.
 2012-02-29 00:46:50 +01:00
antirez eeb34eff52 Added a new API to replicate an additional command after the replication of the currently executed command, in order to propagte the LPUSH originating from RPOPLPUSH and indirectly by BRPOPLPUSH. 2012-02-28 18:03:08 +01:00
antirez d8b1228bf6 propagate() prototype added to redis.h 2012-02-28 16:20:41 +01:00
antirez edba65d090 Var renamed into pushGenericCommand() to better reflect what it means. 2012-02-28 16:17:55 +01:00
antirez ad08d059d0 Added command propagation API. 2012-02-28 16:17:00 +01:00
Jakub Wieczorek 1d6628c088 Fix the build on Mac OS X, where features.h is non-existent 2012-02-26 15:13:05 +01:00
