antirez cb61d003ab Cluster: resharding test now checks AOF consistency.
It's a key invariant that when AOF is enabled, after the cluster
reshards, a crash-recovery event causes all the keys to be still fine
with the expected logical content. Now this is part of unit 04.

antirez d999f5a68e Fix a race that may lead to the active (slave) client to be freed.
In issue #2948 a crash was reported in processCommand(). Later Oran Agra
(@oranagra) traced the bug (in private chat) in the following sequence
of events:

1. Some maxmemory is set.
2. The slave is the currently active client and is executing PING or
   REPLCONF or whatever a slave can send to its master.
3. freeMemoryIfNeeded() is called since maxmemory is set.
4. flushSlavesOutputBuffers() is called by freeMemoryIfNeeded().
5. During slaves buffers flush, a write error could be encoutered in
   writeToClient() or sendReplyToClient() depending on the version of
   Redis. This will trigger freeClient() against the currently active
   client, so a segmentation fault will likely happen in
   processCommand() immediately after the call to freeMemoryIfNeeded().

There are different possible fixes:

1. Add flags to writeToClient() (recent versions code base) so that
   we can ignore the write errors, and use this flag in
   flushSlavesOutputBuffers(). However this is not simple to do in older
   versions of Redis.
2. Use freeClientAsync() during write errors. This works but changes the
   current behavior of releasing clients ASAP when possible. Normally
   we write to clients during the normal event loop processing, in the
   writable client, where there is no active client, so no care must be
   taken.
3. The fix of this commit: to detect that the current client is no
   longer valid. This fix is a bit "ad-hoc", but works across all the
   versions and has the advantage of not changing the remaining
   behavior. Only alters what happens during this race condition,
   hopefully.

antirez a5d27d395f Fix 3.0 merge issues with new MIGRATE. 2015-12-13 10:23:04 +01:00
antirez ea89733833 Cluster: redis-trib: use variadic MIGRATE.
We use the new variadic/pipelined MIGRATE for faster migration.
Testing is not easy because to see the time it takes for a slot to be
migrated requires a very large data set, but even with all the overhead
of migrating multiple slots and to setup them properly, what used to
take 4 seconds (1 million keys, 200 slots migrated) is now 1.6 which is
a good improvement. However the improvement can be a lot larger if:

1. We use large datasets where a single slot has many keys.
2. By moving more than 10 keys per iteration, making this configurable,
   which is planned.

antirez bf09e58d9d Cluster: replica migration with delay.
We wait a fixed amount of time (5 seconds currently) much greater than
the usual Cluster node to node communication latency, before migrating.
This way when a failover occurs, before detecting the new master as a
target for migration, we give the time to its natural slaves (the slaves
of the failed over master) to announce they switched to the new master,
preventing an useless migration operation.

antirez 5ad4f7e0b1 Cluster: more reliable migration tests.
The old version was modeled with two failovers, however after the first
it is possible that another slave will migrate to the new master, since
for some time the new master is not backed by any slave. Probably there
should be some pause after a failover, before the migration. Anyway the
test is simpler in this way, and depends less on timing.

antirez 2e43bcffaf Fix replicas migration by adding a new flag.
Some time ago I broken replicas migration (reported in #2924).
The idea was to prevent masters without replicas from getting replicas
because of replica migration, I remember it to create issues with tests,
but there is no clue in the commit message about why it was so
undesirable.

However my patch as a side effect totally ruined the concept of replicas
migration since we want it to work also for instances that, technically,
never had slaves in the past: promoted slaves.

So now instead the ability to be targeted by replicas migration, is a
new flag "migrate-to". It only applies to masters, and is set in the
following two cases:

1. When a master gets a slave, it is set.
2. When a slave turns into a master because of fail over, it is set.

This way replicas migration targets are only masters that used to have
slaves, and slaves of masters (that used to have slaves... obviously)
and are promoted.

The new flag is only internal, and is never exposed in the output nor
persisted in the nodes configuration, since all the information to
handle it are implicit in the cluster configuration we already have.

antirez 3626699f1f Handle wait3() errors.
My guess was that wait3() with WNOHANG could never return -1 and an
error. However issue #2897 may possibly indicate that this could happen
under non clear conditions. While we try to understand this better,
better to handle a return value of -1 explicitly, otherwise in the
case a BGREWRITE is in progress but wait3() returns -1, the effect is to
match the first branch of the if/else block since server.rdb_child_pid
is -1, and call backgroundSaveDoneHandler() without a good reason, that
will, in turn, crash the Redis server with an assertion.

Kevin McGehee dc03e4c51b Fix master timeout during handshake
This change allows a slave to properly time out a dead master during
the extended asynchronous synchronization state machine.  Now, slaves
will record their last interaction with the master and apply the
replication timeout before a response to the PSYNC request is received.

antirez 30978004b3 redis-cli pipe mode: don't stay in the write loop forever.
The code was broken and resulted in redis-cli --pipe to, most of the
times, writing everything received in the standard input to the Redis
connection socket without ever reading back the replies, until all the
content to write was written.

This means that Redis had to accumulate all the output in the output
buffers of the client, consuming a lot of memory.

Fixed thanks to the original report of anomalies in the behavior
provided by Twitter user @fsaintjacques.

antirez 490847c681 Undo slaves state change on failed rdbSaveToSlavesSockets().
As Oran Agra suggested, in startBgsaveForReplication() when the BGSAVE
attempt returns an error, we scan the list of slaves in order to remove
them since there is no way to serve them currently.

However we check for the replication state BGSAVE_START, which was
modified by rdbSaveToSlaveSockets() before forking(). So when fork fails
the state of slaves remain BGSAVE_END and no cleanup is performed.

This commit fixes the problem by making rdbSaveToSlavesSockets() able to
undo the state change on fork failure.

antirez c20218eb57 Sentinel: fix bug in config rewriting during failover
We have a check to rewrite the config properly when a failover is in
progress, in order to add the current (already failed over) master as
slave, and don't include in the slave list the promoted slave itself.

However there was an issue, the variable with the right address was
computed but never used when the code was modified, and no tests are
available for this feature for two reasons:

1. The Sentinel unit test currently does not test Sentinel ability to
persist its state at all.
2. It is a very hard to trigger state since it lasts for little time in
the context of the testing framework.

However this feature should be covered in the test in some way.

The bug was found by @badboy using the clang static analyzer.

Effects of the bug on safety of Sentinel
===

This bug results in severe issues in the following case:

1. A Sentinel is elected leader.
2. During the failover, it persists a wrong config with a known-slave
entry listing the master address.
3. The Sentinel crashes and restarts, reading invalid configuration from
disk.
4. It sees that the slave now does not obey the logical configuration
(should replicate from the current master), so it sends a SLAVEOF
command to the master (since the slave master is the same) creating a
replication loop (attempt to replicate from itself) which Redis is
currently unable to detect.
5. This means that the master is no longer available because of the bug.

However the lack of availability should be only transient (at least
in my tests, but other states could be possible where the problem
is not recovered automatically) because:

6. Sentinels treat masters reporting to be slaves as failing.
7. A new failover is triggered, and a slave is promoted to master.

Bug lifetime
===

The bug is there forever. Commit 16237d78 actually tried to fix the bug
but in the wrong way (the computed variable was never used! My fault).
So this bug is there basically since the start of Sentinel.

Since the bug is hard to trigger, I remember little reports matching
this condition, but I remember at least a few. Also in automated tests
where instances were stopped and restarted multiple times automatically
I remember hitting this issue, however I was not able to reproduce nor
to determine with the information I had at the time what was causing the
issue.

antirez c2ff9de31b startBgsaveForReplication(): handle waiting slaves state change.
Before this commit, after triggering a BGSAVE it was up to the caller of
startBgsavForReplication() to handle slaves in WAIT_BGSAVE_START in
order to update them accordingly. However when the replication target is
the socket, this is not possible since the process of updating the
slaves and sending the FULLRESYNC reply must be coupled with the process
of starting an RDB save (the reason is, we need to send the FULLSYNC
command and spawn a child that will start to send RDB data to the slaves
ASAP).

This commit moves the responsibility of handling slaves in
WAIT_BGSAVE_START to startBgsavForReplication() so that for both
diskless and disk-based replication we have the same chain of
responsiblity. In order accomodate such change, the syncCommand() also
needs to put the client in the slave list ASAP (just after the initial
checks) and not at the end, so that startBgsavForReplication() can find
the new slave alrady in the list.

Another related change is what happens if the BGSAVE fails because of
fork() or other errors: we now remove the slave from the list of slaves
and send an error, scheduling the slave connection to be terminated.

As a side effect of this change the following errors found by
Oran Agra are fixed (thanks!):

1. rdbSaveToSlavesSockets() on failed fork will get the slaves cleaned
up, otherwise they remain in a wrong state forever since we setup them
for full resync before actually trying to fork.

2. updateSlavesWaitingBgsave() with replication target set as "socket"
was broken since the function changed the slaves state from
WAIT_BGSAVE_START to WAIT_BGSAVE_END via
replicationSetupSlaveForFullResync(), so later rdbSaveToSlavesSockets()
will not find any slave in the right state (WAIT_BGSAVE_START) to feed.

antirez 4363fa1d76 Force slaves to resync after unsuccessful PSYNC.
Using chained replication where C is slave of B which is in turn slave of
A, if B reconnects the replication link with A but discovers it is no
longer possible to PSYNC, slaves of B must be disconnected and PSYNC
not allowed, since the new B dataset may be completely different after
the synchronization with the master.

Note that there are varius semantical differences in the way this is
handled now compared to the past. In the past the semantics was:

1. When a slave lost connection with its master, disconnected the chained
slaves ASAP. Which is not needed since after a successful PSYNC with the
master, the slaves can continue and don't need to resync in turn.

2. However after a failed PSYNC the replication backlog was not reset, so a
slave was able to PSYNC successfully even if the instance did a full
sync with its master, containing now an entirely different data set.

Now instead chained slaves are not disconnected when the slave lose the
connection with its master, but only when it is forced to full SYNC with
its master. This means that if the slave having chained slaves does a
successful PSYNC all its slaves can continue without troubles.

See issue #2694 for more details.

antirez ba3237604f Replication: add REPLCONF CAPA EOF support.
Add the concept of slaves capabilities to Redis, the slave now presents
to the Redis master with a set of capabilities in the form:

    REPLCONF capa SOMECAPA capa OTHERCAPA ...

This has the effect of setting slave->slave_capa with the corresponding
SLAVE_CAPA macros that the master can test later to understand if it
the slave will understand certain formats and protocols of the
replication process. This makes it much simpler to introduce new
replication capabilities in the future in a way that don't break old
slaves or masters.

This patch was designed and implemented together with Oran Agra
(@oranagra).

antirez 27c0ab238b Make sure we re-emit SELECT after each new slave full sync setup.
In previous commits we moved the FULLRESYNC to the moment we start the

also means that we need to re-emit the SELECT statement every time a new
slave starts to accumulate the changes.

To obtian this effect in a more clean way, the function that sends the
FULLRESYNC reply was overloaded with a more important role of also doing
this and chanigng the slave state. So it was renamed to
replicationSetupSlaveForFullResync() to better reflect what it does now.

antirez 9d2972183e PSYNC initial offset fix.
This commit attempts to fix a bug involving PSYNC and diskless
replication (currently experimental) found by Yuval Inbar from Redis Labs
and that was later found to have even more far reaching effects (the bug also
exists when diskstore is off).

The gist of the bug is that, a Redis master replies with +FULLRESYNC to
a PSYNC attempt that fails and requires a full resynchronization.
However, the baseline offset sent along with FULLRESYNC was always the
current master replication offset. This is not ok, because there are
many reasosn that may delay the RDB file creation. And... guess what,
the master offset we communicate must be the one of the time the RDB
was created. So for example:

1) When the BGSAVE for replication is delayed since there is one
   already but is not good for replication.
2) When the BGSAVE is not needed as we attach one currently ongoing.
3) When because of diskless replication the BGSAVE is delayed.

In all the above cases the PSYNC reply is wrong and the slave may
reconnect later claiming to need a wrong offset: this may cause
data curruption later.

antirez b029ff11b6 Client timeout handling improved.
The previos attempt to process each client at least once every ten
seconds was not a good idea, because:

1. Usually because of the past min iterations set to 50, you get much
better processing period most of the times.

2. However when there are many clients and a normal setting for
server.hz, the edge case is triggered, and waiting 10 seconds for a
BLPOP that asked for 1 second is not ok.

3. Moreover, because of the high min-itereations limit of 50, when HZ
was set to an high value, the actual behavior was to process a lot of
clients per second.

Also the function checking for timeouts called gettimeofday() at each
iteration which can be costly.

The new implementation will try to process each client once per second,
gets the current time as argument, and does not attempt to process more
than 5 clients per iteration if not needed.

So now:

1. The CPU usage of an idle Redis process is the same or better.
2. The CPU usage of a busy Redis process is the same or better.
3. However a non trivial amount of work may be performed per iteration
when there are many many clients. In this particular case the user may
want to raise the "HZ" value if needed.

Btw with 4000 clients it was still not possible to noticy any actual
latency created by processing 400 clients per second, since the work
performed for each client is pretty small.

antirez 4e8759c65e Use best effort address binding to connect to the master
We usually want to reach the master using the address of the interface
Redis is bound to (via the "bind" config option). That's useful since
the master will get (and publish) the slave address getting the peer
name of the incoming socket connection from the slave.

However, when this is not possible, for example because the slave is
bound to the loopback interface but repliaces from a master accessed via
an external interface, we want to still connect with the master even
from a different interface: in this case it is not really important that
the master will provide any other address, while it is vital to be able
to replicate correctly.

therealbill b065f4441b Making sentinel flush config on +slave
Originally, only the +slave event which occurs when a slave is
reconfigured during sentinelResetMasterAndChangeAddress triggers a flush
of the config to disk.  However, newly discovered slaves don't
apparently trigger this flush but do trigger the +slave event issuance.

So if you start up a sentinel, add a master, then add a slave to the
master (as a way to reproduce it) you'll see the +slave event issued,
but the sentinel config won't be updated with the known-slave entry.

This change makes sentinel do the flush of the config if a new slave is
deteted in sentinelRefreshInstanceInfo.

antirez bd99b26bc5 Sentinel: remove useless sentinelFlushConfig() call
To rewrite the config in the loop that adds slaves back after a master
reset, in order to handle switching to another master, is useless: it
just adds latency since there is an fsync call in the inner loop,
without providing any additional guarantee, but the contrary, since if
after the first loop iteration the server crashes we end with just a
single slave entry losing all the other informations.

It is wiser to rewrite the config at the end when the full new
state is configured.

antirez 315e3b14ef Fix Sentinel memory leak (hiredis bug)
This fixes issue #2535, that was actually an hiredis library bug (I
submitted an issue and fix to the redis/hiredis repo as well).

When an asynchronous hiredis connection subscribes to a Pub/Sub channel
and gets an error, and in other related conditions, the function
redisProcessCallbacks() enters a code path where the link is
disconnected, however the function returns before freeing the allocated
reply object. This causes a memory leak. The memory leak was trivial to
trigger in Redis Sentinel, which uses hiredis, every time we tried to
subscribe to an instance that required a password, in case the Sentinel
was configured either with the wrong password or without password at
all. In this case, the -AUTH error caused the leaking code path to be
executed.

It was verified with Valgrind that after this change the leak no longer
happens in Sentinel with a misconfigured authentication password.

antirez 7e78ab4b6f Replication: disconnect blocked clients when switching to slave role.
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.

antirez 3468cd3664 Cluster: redirection refactoring + handling of blocked clients.
There was a bug in Redis Cluster caused by clients blocked in a blocking
list pop operation, for keys no longer handled by the instance, or
in a condition where the cluster became down after the client blocked.

A typical situation is:

1) BLPOP <somekey> 0
2) <somekey> hash slot is resharded to another master.

The client will block forever int this case.

A symmentrical non-cluster-specific bug happens when an instance is
turned from master to slave. In that case it is more serious since this
will desynchronize data between slaves and masters. This other bug was
discovered as a side effect of thinking about the bug explained and
fixed in this commit, but will be fixed in a separated commit.

antirez 62893f5b9f Cluster: better cluster state transiction handling.
Before we relied on the global cluster state to make sure all the hash
slots are linked to some node, when getNodeByQuery() is called. So
finding the hash slot unbound was checked with an assertion. However
this is fragile. The cluster state is often updated in the
clusterBeforeSleep() function, and not ASAP on state change, so it may
happen to process clients with a cluster state that is 'ok' but yet
certain hash slots set to NULL.

With this commit the condition is also checked in getNodeByQuery() and
reported with a identical error code of -CLUSTERDOWN but slightly
different error message so that we have more debugging clue in the
future.

Root cause of issue #2288.

antirez 4793ea982a redis-cli: interactive reconnection for latency modes.
--stat mode already used to reconnect automatically if the server is no
longer available. This is useful since this is an interactive mode used
for debugging, however the same applies to --latency and --latency-dist
modes, so now both use the reconnecting command execution as well.

The reconnection code was modified to use basic VT100 escape sequences
in order to play better with different kinds of output on the screen
when the reconnection happens, and to hide the reconnection attempt
output when finally the reconnection happens.

Otherwise it is impossible to receive the majority of failure reports in

Still with a 200 nodes cluster, 20 gossip sections are a very reasonable
amount of bytes to send.

A side effect of this change is also fater cluster nodes joins for large
clusters, because the cluster layout makes less time to propagate.

On Darwin /dev/urandom depletes terribly fast. This is not an issue

example during nodes handshakes. Our IDs need just to be unique without
other strong crypto requirements, so this commit turns the function into
something that gets a 20 bytes seed from /dev/urandom, and produces the
rest of the output just using SHA1 in counter mode.

antirez df1a7fc4fe Cluster: fetch my IP even if msg is not MEET for the first time.
In order to avoid that misconfigured cluster nodes at some time may
force an IP update on other nodes, it is required that nodes update
their own address only on MEET messages. However it does not make sense
to do this the first time a node is contacted and yet does not have an
IP, we just risk that myself->ip remains not assigned if there are
messages lost or cluster creation procedures that don't make sure
everybody is targeted by at least one incoming MEET message.

Also fix the logging of the IP switch avoiding the :-1 tail.

antirez 69efb59ac7 Mark PFCOUNT as read-only, even if not true.
PFCOUNT is technically speaking a write command, since the cached value
of the HLL is exposed in the data structure (design error, mea culpa), and
can be modified by PFCOUNT.

However if we flag PFCOUNT as "w", read only slaves can't execute the
command, which is a problem since there are environments where slaves
are used to scale PFCOUNT reads.

Nor it is possible to just prevent PFCOUNT to modify the data structure
in slaves, since without the cache we lose too much efficiency.

So while this commit allows slaves to create a temporary inconsistency
(the strings representing the HLLs in the master and slave can be
different in certain moments) it is actually harmless.

In the long run this should be probably fixed by turning the HLL into a
more opaque representation, for example by storing the cached value in
the part of the string which is not exposed (this should be possible
with SDS strings).

Matt Stancliff 03ca2231f0 Lua: Upgrade cjson to 2.1.0 (2012-03-01)
The new cjson has some improvements over our current version including
increased platform compatability, a new resource limit to restrict
decode depth, and better invalid number handling.

One minor change was required to deps/Makefile because this version
of cjson doesn't export itself globally, so we added a quick little
define of -DENABLE_CJSON_GLOBAL.

cjson now has an optional higher performing float parsing interface,
but we are not including it (g_fmt.c, dtoa.c) because it requires
endianness declaration during compile time.

This commit is exactly lua_cjson.c from 2.1.0 with one minor
change of altering the two Lua includes for local search
instead of system-wide importing.

Matt Stancliff d071e5feab Lua: Add bitop
A few people have written custom C commands because bit
manipulation isn't exposed through Lua.  Let's give
them Mike Pall's bitop.

This adds bitop 1.0.2 (2012-05-08) from http://bitop.luajit.org/

bitop is imported as "bit" into the global namespace.

New Lua commands: bit.tobit, bit.tohex, bit.bnot, bit.band, bit.bor, bit.bxor,
bit.lshift, bit.rshift, bit.arshift, bit.rol, bit.ror, bit.bswap

Verification of working (the asserts would abort on error, so (nil) is correct):
127.0.0.1:6379> eval "assert(bit.tobit(1) == 1); assert(bit.band(1) == 1); assert(bit.bxor(1,2) == 3); assert(bit.bor(1,2,4,8,16,32,64,128) == 255)" 0
(nil)
127.0.0.1:6379> eval 'assert(0x7fffffff == 2147483647, "broken hex literals"); assert(0xffffffff == -1 or 0xffffffff == 2^32-1, "broken hex literals"); assert(tostring(-1) == "-1", "broken tostring()"); assert(tostring(0xffffffff) == "-1" or tostring(0xffffffff) == "4294967295", "broken tostring()")' 0
(nil)

Tests also integrated into the scripting tests and can be run with:
./runtest --single unit/scripting

Tests are excerpted from `bittest.lua` included in the bitop distribution.

antirez 90911905f8 Diskless SYNC: fix RDB EOF detection.
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.

antirez 55e9a71317 Diskless replication: rio fdset target new supports buffering.
To perform a socket write() for each RDB rio API write call was
extremely unefficient, so now rio has minimal buffering capabilities.
Writes are accumulated into a buffer and only when a given limit is
reacehd are actually wrote to the N slaves FDs.

Trivia: rio lacked support for buffering since our targets were:

1) Memory buffers.
2) C standard I/O.

Both were buffered already.

If we turn from diskless to disk-based replication via CONFIG SET, we
need a way to start a BGSAVE if there are slaves alerady waiting for a
BGSAVE to start. Normally with disk-based replication we do it as soon
as the previous child exits, but when there is a configuration change
via CONFIG SET, we may have slaves in WAIT_BGSAVE_START state without
an RDB background process currently active.

Fdset target is used when we want to write an RDB file directly to
slave's sockets. In this setup as long as there is a single slave that
is still receiving our payload, we want to continue sennding instead of
aborting. However rio calls should abort of no FD is ok.

Also we want the errors reported so that we can signal the parent who is
ok and who is broken, so there is a new set integers with the state of
each fd. Zero is ok, non-zero is the errno of the failure, if avaialble,
or a generic EIO.

antirez 0ad99ccf75 DEBUG POPULATE two args form implemented.
The old DEBUG POPULATE form for automatic creation of test keys is:

    DEBUG POPULATE <count>

Now an additional form is available:

    DEBUG POPULATE <count> <prefix>

When prefix is not specified, it defaults to "key", so the keys are
named incrementally from key:0 to key:<count-1>. Otherwise the specified
prefix is used instead of "key".

The command is useful in order to populate different Redis instances
with key names guaranteed to don't collide. There are other debugging
uses, for example it is possible to add additional N keys using a count
of N and a random prefix at every call.

This fixes a potential bug that was never observed in practice since

happens to always be populated.

Howver technically connect(2) with a non blocking socket may return an
error synchronously, so before this fix the code was not correct.

It is not clear if files open in append only mode will automatically fix

antirez ac76d56e6f On AOF end of file, truncate the AOF to last valid command.
Recently we introduced the ability to load truncated AOFs, but
unfortuantely the support was broken since the server, after loading the
truncated AOF, continues appending to the file that is corrupted at the
end. The problem is fixed only in the next AOF rewrite.

This commit fixes the issue by truncating the AOF to the last valid
opcode, and aborting if it is not possible to truncate the file
correctly.

This means that there is a changing majority on partitions, even if

Kashif Rasul 54e054fff3 Fix issues raised by clang analyzer
Modified by @antirez since the original fix to genInfoString() looked
weak. Probably the clang analyzer complained about `section` being
possibly NULL, and strcasecmp() called with a NULL pointer. In the
practice this can never happen, still for the sake of correctness
the right fix is not to modify only the first call, but to set `section`
to the value of "default" if it happens to be NULL.

antirez d6f309d4c0 Faster ll2string() implementation.
Based on ideas documented in this blog post:

https://www.facebook.com/notes/facebook-engineering/three-optimization-tips-for-c/10151361643253920

The original code was modified to handle signed integers, reformetted to
fit inside the Redis code base, and was stress-tested with a program
in order to validate the implementation against snprintf().

Redis was measured to be measurably faster from the point of view of
clients in real-world operations because of this change, since sometimes
number to string conversion is used extensively (for example every time
a GET results into an integer encoded object to be returned to the
user).

antirez dd50295de6 PFSELFTEST: less false positives.
This is just a quickfix, for the nature of the test the right way to fix

this possibility we may end testing with too much "large" error ranges.

antirez 5e88bd0526 ZUNIONSTORE reimplemented for speed.
The user @kjmph provided excellent ideas to improve speed of ZUNIONSTORE
(in certain cases by many order of magnitude), together with an
implementation of the ideas.

While the ideas were sounding, the implementation could be improved both
in terms of speed and clearness, so that's my attempt at reimplementing
the speedup proposed, trying to improve by directly using just a
dictionary with an embedded score inside, and reusing the single-pass
aggregate + order-later approach.

Note that you can't apply this commit without applying the previous
commit in this branch that adds a double in the dictEntry value union.

antirez 955b25624e CLUSTER RESET: Flush dataset if node is a slave.
For non-empty masters, CLUSTER RESET is denied, and the user requires to
start to reset a node by explicitly clearing it with FLUSHALL.
However CLUSTER RESET when executed with slaves don't have this
restrictions since data is just a replica of the master, and with
read-only slaves it is also not possible to remove the data set. However
the node was turned from slave to master after a reset, without touching
the old slave data. This is 99.99% of times not appropriate and forces
full resets to follow this path to work with both slave and master
nodes:

    FLUSHALL
    CLUSTER RESET HARD
    FLUSHALL

Since we need the first flushall for masters, and the second for slaves.

This commit changes the behavior so that CLUSTER RESET removes the data set
of a slave node during a reset, in the moment it gets turned into a master,
so the new pattern is simply:

    FLUSHALL (that may fail for slaves)
    CLUSTER RESET

make sure that the elected slave was replicating correctly with the
master.

REDIS_PUBSUB that is simpler to test for. Moreover in order to manage
this flag some code was refactored.

michael-grunder d75fc09354 Fix OBJECT arity
Previously, the command definition for the OBJECT command specified
a minimum of two args (and that it was variadic), which meant that

When cluster was enabled, it would result in an assertion/SEGFAULT
when Redis was attempting to extract keys.

It appears that OBJECT is not variadic, and only ever takes 3 args.

antirez cc7b10cb52 Better "final read from parent" algorithm in rewriteAppendOnlyFile*(.
We now wait up to 1 second for diff data to come from the parent,
however we use poll(2) to wait for more data, and use a counter of
contiguous failures to get data for N times (set to 20 experimentally
after different tests) as an early stop condition to avoid wasting 1
second when the write traffic is too low.

antirez 44cf7395a2 Latency monitor: collect slow commands.
We introduce the distinction between slow and fast commands since those
are two different sources of latency. An O(1) or O(log N) command without
side effects (can't trigger deletion of large objects as a side effect of
its execution) if delayed is a symptom of inherent latency of the system.

A non-fast command (commands that may run large O(N) computations) if
delayed may just mean that the user is executing slow operations.

The advices LATENCY should provide in this two different cases are
different, so we log the two classes of commands in a separated way.

Matt Stancliff 60d62a99d2 Cluster: Add COMMANDS command
COMMANDS returns a nested multibulk reply for each
command in the command table.  The reply for each
command contains:
  - command name
  - arity
  - array of command flags
  - start key position
  - end key position
  - key offset step
  - optional: if the keys are not deterministic and
    Redis uses an internal key evaluation function,
    the 6th field appears and is defined as a status
    reply of: REQUIRES ARGUMENT PARSING

Cluster clients need to know where the keys are in each
command to implement proper routing to cluster nodes.

Redis commands can have multiple keys, keys at offset steps, or other
issues where you can't always assume the first element after
the command name is the cluster routing key.

Using the information exposed by COMMANDS, client implementations
can have live, accurate key extraction details for all commands.

Also implements COMMANDS INFO [commands...] to return only a
specific set of commands instead of all 160+ commands live in Redis.

Matt Stancliff 77fb9fd4fd Allow __powerpc__ to define HAVE_ATOMIC too
From mailing list post https://groups.google.com/forum/#!topic/redis-db/D3k7KmJmYgM

In the file “config.h”, the definition HAVE_ATOMIC is used to indicate
if an architecture on which redis is implemented supports atomic
synchronization primitives.  Powerpc  supports atomic synchronization
primitives, however, it is not listed as one of the architectures
supported in config.h. This patch  adds the __powerpc__ to the list of
architectures supporting these primitives. The improvement of redis
due to the atomic synchronization on powerpc is significant,
around 30% to 40%, over the default implementation using pthreads.

This proposal adds __powerpc__ to the list of architectures designated
to support atomic builtins.
2014-06-26 15:16:23 +02:00
Matt Stancliff 27e30e2f8b Allow atomic memory count update with C11 builtins
From mailing list post https://groups.google.com/forum/#!topic/redis-db/QLjiQe4D7LA

In zmalloc.c the following primitives are currently used
to synchronize access to single global variable:
__sync_add_and_fetch
__sync_sub_and_fetch

In some architectures such as powerpc these primitives are overhead
intensive. More efficient C11 __atomic builtins are available with
newer GCC versions, see
http://gcc.gnu.org/onlinedocs/gcc-4.8.2/gcc/_005f_005fatomic-Builtins.html#_005f_005fatomic-Builtins

By substituting the following  __atomic… builtins:
__atomic_add_fetch
__atomic_sub_fetch

the performance improvement on certain architectures such as powerpc can be significant,
around 10% to 15%, over the implementation using __sync builtins while there is only slight uptick on
Intel architectures because it was already enforcing Intel Strongly ordered memory semantics.

The selection of __atomic built-ins can be predicated on the definition of ATOMIC_RELAXED
which Is available on in gcc 4.8.2 and later versions.

antirez a7bef1bb7c CLUSTER SLOTS: don't output failing slaves.
While we have to output failing masters in order to provide an accurate
map (that may be the one of a Redis Cluster in down state because not
all slots are served by a working master), to provide slaves in FAIL
state is not a good idea since those are not necesarely needed, and the
client will likely incur into a latency penalty trying to connect with a
slave which is down.

Note that this means that CLUSTER SLOTS does not provide a *complete*
map of slaves, however this would not be of any help since slaves may be
added later, and a client that needs to scale reads and requires to
stay updated with the list of slaves, need to do a refresh of the map
from time to time, anyway.

Matt Stancliff 237188bf1b Cluster: Add CLUSTER SLOTS command
CLUSTER SLOTS returns a Redis-formatted mapping from
slot ranges to IP/Port pairs serving that slot range.

The outer return elements group return values by slot ranges.

The first two entires in each result are the min and max slots for the range.

The third entry in each result is guaranteed to be either
an IP/Port of the master for that slot range - OR - null
if that slot range, for some reason, has no master

The 4th and higher entries in each result are replica instances
for the slot range.

antirez 6adf0e092c Sentinel test: more correct sentinels config reset.
In the initialization test for each instance we used to unregister the
old master and register it again to clear the config.
However there is a race condition doing this: as soon as we unregister
and re-register "mymaster", another Sentinel can update the new
configuration with the old state because of gossip "hello" messages.

So the correct procedure is instead, unregister "mymaster" from all the
sentinel instances, and re-register it everywhere again.

antirez 6588ef2944 Sentinel: handle SRI_PROMOTED flag correctly.
Lack of check of the SRI_PROMOTED flag caused Sentienl to act with the
promoted slave turned into a master during failover like if it was a
normal instance.

Normally this problem was not apparent because during real failovers the
old master is down so the bugged code path was not entered, however with
manual failovers via the SENTINEL FAILOVER command, the problem was
easily triggered.

This commit prevents promoted slaves from getting reconfigured, moreover
we now explicitly check that during a failover the slave turning into a
master is the one we selected for promotion and not a different one.

antirez b7dd451892 Assign an unique non-repeating ID to each new client.
This will be used by CLIENT KILL and is also a good way to ensure a
given client is still the same across CLIENT LIST calls.

The output of CLIENT LIST was modified to include the new ID, but this
change is considered to be backward compatible as the API does not imply
you can do positional parsing, since each filed as a different name.

antirez d97d1a6430 Client types generalized.
Because of output buffer limits Redis internals had this idea of type of
clients: normal, pubsub, slave. It is possible to set different output
buffer limits for the three kinds of clients.

However all the macros and API were named after output buffer limit
classes, while the idea of a client type is a generic one that can be
reused.

This commit does two things:

1) Rename the API and defines with more general names.
2) Change the class of clients executing the MONITOR command from "slave"
   to "normal".

"2" is a good idea because you want to have very special settings for
slaves, that are not a good idea for MONITOR clients that are instead
normal clients even if they are conceptually slave-alike (since it is a
push protocol).

The backward-compatibility breakage resulting from "2" is considered to
be minimal to care, since MONITOR is a debugging command, and because
anyway this change is not going to break the format or the behavior, but
just when a connection is closed on big output buffer issues.

antirez 2b57d96ea0 Fix semantics of Lua calls to SELECT.
Lua scripts are executed in the context of the currently selected
database (as selected by the caller of the script).

However Lua scripts are also free to use the SELECT command in order to
affect other DBs. When SELECT is called frm Lua, the old behavior, before
this commit, was to automatically set the Lua caller selected DB to the
last DB selected by Lua. See for example the following sequence of
commands:

    SELECT 0
    SET x 10
    EVAL "redis.call('select','1')" 0
    SET x 20

Before this commit after the execution of this sequence of commands,
we'll have x=10 in DB 0, and x=20 in DB 1.

Because of the problem above, there was a bug affecting replication of
Lua scripts, because of the actual implementation of replication. It was
possible to fix the implementation of Lua scripts in order to fix the
issue, but looking closely, the bug is the consequence of the behavior
of Lua ability to set the caller's DB.

Under the old semantics, a script selecting a different DB, has no simple
ways to restore the state and select back the previously selected DB.
Moreover the script auhtor must remember that the restore is needed,
otherwise the new commands executed by the caller, will be executed in
the context of a different DB.

So this commit fixes both the replication issue, and this hard-to-use
semantics, by removing the ability of Lua, after the script execution,
to force the caller to switch to the DB selected by the Lua script.

The new behavior of the previous sequence of commadns is to just set
X=20 in DB 0. However Lua scripts are still capable of writing / reading
from different DBs if needed.

WARNING: This is a semantical change that will break programs that are
conceived to select the client selected DB via Lua scripts.

This fixes issue #1811.

antirez 0f4b925de5 Scripting: Fix for a #1118 regression simplified.
It is more straightforward to just test for a numerical type avoiding
Lua's automatic conversion. The code is technically more correct now,
however Lua should automatically convert to number only if the original
type is a string that "looks like a number", and not from other types,
so practically speaking the fix is identical AFAIK.

Matt Stancliff 9ca83c82bf Scripting: Fix regression from #1118
The new check-for-number behavior of Lua arguments broke

The Lua number check would convert the string to a number, but
that breaks user data because
Lua numbers have limited precision compared to an arbitrarily
precise number wrapped in a string.

Regression fixed and new test added.

Matt Stancliff 7fc1fc8ca7 Fix blocking operations from missing new lists
Behrad Zari discovered [1] and Josiah reported [2]: if you block
and wait for a list to exist, but the list creates from
a non-push command, the blocked client never gets notified.

This commit adds notification of blocked clients into
the DB layer and away from individual commands.

Lists can be created by [LR]PUSH, SORT..STORE, RENAME, MOVE,
and RESTORE.  Previously, blocked client notifications were
only triggered by [LR]PUSH.  Your client would never get
notified if a list were created by SORT..STORE or RENAME or
a RESTORE, etc.

Blocked client notification now happens in one unified place:
  - dbAdd() triggers notification when adding a list to the DB

Two new tests are added that fail prior to this commit.

All test pass.

antirez c3967f42d7 Scripting: better Lua number -> string conversion in luaRedisGenericCommand().
The lua_to*string() family of functions use a non optimal format
specifier when converting integers to strings. This has both the problem
of the number being converted in exponential notation, which we don't
use as a Redis return value when floating point numbers are involed,
and, moreover, there is a loss of precision since the default format
specifier is not able to represent numbers that must be represented
exactly in the IEEE 754 number mantissa.

The new code handles it as a special case using a saner conversion.

This fixes issue #1118.

antirez 5efa5501e8 CLUSTER RESET implemented.
The new command is able to reset a cluster node so that it starts again
as a fresh node. By default the command performs a soft reset (the same
as calling it as CLUSTER RESET SOFT), and the following steps are
performed:

1) All slots are set as unassigned.
2) The list of known nodes is flushed.
3) Node is set as master if it is a slave.

When an hard reset is performed with CLUSTER RESET HARD the following
additional operations are performed:

4) A new Node ID is created at random.
5) Epochs are set to 0.

CLUSTER RESET is useful both when the sysadmin wants to reconfigure a
node with a different role (for example turning a slave into a master)
and for testing purposes.

It also may play a role in automatically provisioned Redis Clusters,
since it allows to reset a node back to the initial state in order to be
reconfigured.

antirez b8a71e5a77 Cluster: better handling of stolen slots.
The previous code handling a lost slot (by another master with an higher
configuration for the slot) was defensive, considering it an error and
putting the cluster in an odd state requiring redis-cli fix.

This was changed, because actually this only happens either in a
legitimate way, with failovers, or when the admin messed with the config
in order to reconfigure the cluster. So the new code instead will try to
make sure that the keys stored match the new slots map, by removing all
the keys in the slots we lost ownership from.

The function that deletes the keys from the lost slots is called only
if the node does not lose all its slots (resulting in a reconfiguration
as a slave of the node that got ownership). This is an optimization
since the replication code will anyway flush all the instance data in
a faster way.

Using CLUSTER FAILOVER FORCE it is now possible to failover a master in

2) No data age of the slave is checked. Evan a slave with very old data
   can manually failover a master in this way.

Automatic failovers only happen in Redis Cluster if the slave trying to

manual failovers, since these are initiated by the sysadmin that, in
theory, knows what she is doing when a slave is selected to be promoted.

antirez 83c92d50a6 Cluster: bulk-accept new nodes connections.
The same change was operated for normal client connections. This is
important for Cluster as well, since when a node rejoins the cluster,
when a partition heals or after a restart, it gets flooded with new
connection attempts by all the other nodes trying to form a full
mesh again.

antirez 6eadeb7236 Sentinel: log when a failover will be attempted again.
When a Sentinel performs a failover (successful or not), or when a
Sentinel votes for a different Sentinel trying to start a failover, it
sets a min delay before it will try to get elected for a failover.

While not strictly needed, because if multiple Sentinels will try
to failover the same master at the same time, only one configuration
will eventually win, this serialization is practically very useful.
Normal failovers are cleaner: one Sentinel starts to failover, the
others update their config when the Sentinel performing the failover
is able to get the selected slave to move from the role of slave to the
one of master.

However currently this timeout was implicit, so users could see
Sentinels not reacting, after a failed failover, for some time, without
giving any feedback in the logs to the poor sysadmin waiting for clues.

This commit makes Sentinels more verbose about the delay: when a master
is down and a failover attempt is not performed because the delay has
still not elaped, something like that will be logged:

    Next failover delay: I will not start a failover

antirez 35b94422f6 Scripting test: check that Lua can call commands rewirting argv.
SPOP, tested in the new test, is among the commands rewritng the
client->argv argument vector (it gets rewritten as SREM) for command
replication purposes.

Because of recent optimizations to client->argv caching in the context
of the Lua internal Redis client, it is important to test for SPOP to be
callable from Lua without bad effects to the other commands.

antirez c4c7389fea CLUSTER SET-CONFIG-EPOCH implemented.
Initially Redis Cluster accepted that after cluster creation all the
nodes were at configEpoch 0, evolving from zero as failovers happen.

However later the semantic was made more strict in order to make sure a
cluster has always all the master nodes with a different configEpoch,
which is more robust in some corner case (especially resulting from
errors by the system administrator).

To assign different configEpochs to different nodes at startup was a
task performed naturally by the config conflicts resolution algorithm
(see the Cluster specification). However this works well only for small
clusters or when there are actually just a few collisions, since it is
designed for exceptional cases.

When a large cluster is created hundred of nodes can be at epoch 0, so
the conflict resolution code is slow to provide an unique config to each
node. For this reason this new command was introduced. It can be called
only when a node is totally fresh: no other nodes known, and configEpoch
set to zero, so it is safe even against misuses.

redis-trib will use the new command in order to start the cluster
already setting an incremental unique config to every node.

antirez 0ab06bb500 sdscatfmt() added to SDS library.
sdscatprintf() relies on printf() family libc functions and is sometimes
too slow in critical code paths. sdscatfmt() is an alternative which is:

1) Far less capable.
2) Format specifier uncompatible.
3) Faster.

It is suitable to be used in those speed critical code paths such as
CLIENT LIST output generation.

antirez cdd2bd5632 Process events with processEventsWhileBlocked() when blocked.
When we are blocked and a few events a processed from time to time, it
is smarter to call the event handler a few times in order to handle the
accept, read, write, close cycle of a client in a single pass, otherwise
there is too much latency added for clients to receive a reply while the
server is busy in some way (for example during the DB loading).
2014-04-28 18:17:02 +02:00
antirez 357b039fdb Accept multiple clients per iteration.
When the listening sockets readable event is fired, we have the chance
to accept multiple clients instead of accepting a single one. This makes
Redis more responsive when there is a mass-connect event (for example
after the server startup), and in workloads where a connect-disconnect
pattern is used often, so that multiple clients are waiting to be
accepted continuously.

As a side effect, this commit makes the LOADING, BUSY, and similar
errors much faster to deliver to the client, making Redis more
responsive when there is to return errors to inform the clients that the
server is blocked in an not interruptible operation.

other reason.

antirez 71d71814a9 Lock nodes.conf to avoid multiple processes using the same file.
This was a common source of problems among users.
The solution adopted is not bullet-proof as if the user deletes the
nodes.conf file manually, and starts a new instance with the same
nodes.conf file path, two instances will use the same file. However
following this reasoning the user may drop a nuclear bomb into the
datacenter as well.

The internal HLL raw encoding used by PFCOUNT when merging multiple keys

After running a few benchmarks, 3000 looks like a reasonable value to

still not huge.

This covers all the cases where the dense representation would use N
orders of magnitude more space, like in the case of many HLLs with
carinality of a few tens or hundreds.

It is not impossible that in the future this gets user configurable,
however it is easy to pick an unreasoable value just looking at savings
in the space dimension without checking what happens in the time
dimension.

antirez 63ba5f5a8c Changed HyperLogLog hash seed to a non-zero value.
Using a seed of zero has the side effect of having the empty string
hashing to what is a very special case in the context of HyperLogLog: a
very long run of zeroes.

This did not influenced the correctness of the result with 16k registers
because of the harmonic mean, but still it is inconvenient that a so
obvious value maps to a so special hash.

The seed 0xadc83b19 is used instead, which is the first 64 bits of the
SHA1 of the empty string.

antirez 7acccc7ef9 HyperLogLog approximated cardinality caching.
The more we add elements to an HyperLogLog counter, the smaller is
the probability that we actually update some register.

From this observation it is easy to see how it is possible to use
caching of a previously computed cardinality and reuse it to serve
HLLCOUNT queries as long as no register was updated in the data
structure.

This commit does exactly this by using just additional 8 bytes for the
data structure to store a 64 bit unsigned integer value cached
cardinality. When the most significant bit of the 64 bit integer is set,
it means that the value computed is no longer usable since at least a
single register was modified and we need to recompute it at the next
call of HLLCOUNT.

The value is always stored in little endian format regardless of the
actual CPU endianess.

antirez 8be30eca17 String value unsharing refactored into proper function.
All the Redis functions that need to modify the string value of a key in
a destructive way (APPEND, SETBIT, SETRANGE, ...) require to make the

We need to be sure that you can save a dataset in a Redis instance,

So 32 and 64 bit, little or bit endian, must all guarantee to output the
same hash for the same element.

antirez f704678d07 HyperLogLog internal representation modified.
The new representation is more obvious, starting from the LSB of the
first byte and using bits going to MSB, and passing to next byte as
needed.

There was also a subtle error: first two bits were unused, everything
was carried over on the right of two bits, even if it worked because of
the code requirement of always having a byte more at the end.

During the rewrite the code was made safer trying to avoid undefined
behavior due to shifting an uint8_t for more than 8 bits.

redis-trib used to allocate slots not considering fractions of nodes
when computing the slots_per_node amount. So the fractional part was
carried over till the end of the allocation, where the last node
received a few more slots than any other (or a lot more if the cluster
was composed of many nodes).

The computation was changed to allocate slots more evenly when they are
not exactly divisible for the number of masters we have.

antirez 431573ae98 Cluster: configEpoch collisions resolution.
The slave election in Redis Cluster guarantees that slaves promoted to

manual reshardings, software bugs and operational errors may in theory
cause two nodes to have the same configEpoch.

This commit introduces a mechanism to eventually always end with different
configEpochs if a collision ever happens.

As a (wanted) side effect, this also ensures that after a new cluster
is created, all nodes will end with a different configEpoch automatically.

Matt Stancliff 1e7b99809b Fix infinite loop on startup if ulimit too low
Fun fact: rlim_t is an unsigned long long on all platforms.

Continually subtracting from a rlim_t makes it get smaller
and smaller until it wraps, then you're up to 2^64-1.

This was causing an infinite loop on Redis startup if
your ulimit was extremely (almost comically) low.

The case of (f > oldlimit) would never be met in a case like:

    f = 150
    while (f > 20) f -= 128

Since f is unsigned, it can't go negative and would
take on values of:

    Iteration 1: 150 - 128 => 22
    Iteration 2:  22 - 128 => 18446744073709551510
    Iterations 3-∞: ...

To catch the wraparound, we use the previous value of f
stored in limit.rlimit_cur.  If we subtract from f and
get a larger number than the value it had previously,
we print an error and exit since we don't have enough
file descriptors to help the user at this point.

Thanks to @bs3g for the inspiration to fix this problem.
Patches existed from @bs3g at antirez#1227, but I needed to repair a few other
parts of Redis simultaneously, so I didn't get a chance to use them.

Matt Stancliff f701a347b8 Improve error handling around setting ulimits
The log messages about open file limits have always
been slightly opaque and confusing.  Here's an attempt to
fix their wording, detail, and meaning.  Users will have a
better understanding of how to fix very common problems
with these reworded messages.

Also, we handle a new error case when maxclients becomes less
than one, essentially rendering the server unusable.  We
now exit on startup instead of leaving the user with a server
unable to handle any connections.

This fixes antirez#356 as well.
2014-03-25 09:07:17 +01:00
Matt Stancliff 6f4be45997 Replace magic 32 with REDIS_EVENTLOOP_FDSET_INCR
32 was the additional number of file descriptors Redis
would reserve when managing a too-low ulimit.  The
number 32 was in too many places statically, so now
we use a macro instead that looks more appropriate.

When Redis sets up the server event loop, it uses:
    server.maxclients+REDIS_EVENTLOOP_FDSET_INCR

So, when reserving file descriptors, it makes sense to
reserve at least REDIS_EVENTLOOP_FDSET_INCR FDs instead
of only 32.  Currently, REDIS_EVENTLOOP_FDSET_INCR is
set to 128 in redis.h.

Also, I replaced the static 128 in the while f < old loop
with REDIS_EVENTLOOP_FDSET_INCR as well, which results
in no change since it was already 128.

Impact: Users now need at least maxclients+128 as
their open file limit instead of maxclients+32 to obtain
actual "maxclients" number of clients.  Redis will carve
the extra REDIS_EVENTLOOP_FDSET_INCR file descriptors it
needs out of the "maxclients" range instead of failing
to start (unless the local ulimit -n is too low to accomidate
the request).
2014-03-25 09:07:17 +01:00
Matt Stancliff 49b576cb6c Fix maxclients error handling
Everywhere in the Redis code base, maxclients is treated
as an int with (int)maxclients or `maxclients = atoi(source)`,
so let's make maxclients an int.

This fixes a bug where someone could specify a negative maxclients
on startup and it would work (as well as set maxclients very high)
because:

    unsigned int maxclients;
    char *update = "-300";
    maxclients = atoi(update);
    if (maxclients < 1) goto fail;

But, (maxclients < 1) can only catch the case when maxclients
is exactly 0.  maxclients happily sets itself to -300, which isn't
-300, but rather 4294966996, which isn't < 1, so... everything
"worked."

maxclients config parsing checks for the case of < 1, but maxclients
CONFIG SET parsing was checking for case of < 0 (allowing
maxclients to be set to 0).  CONFIG SET parsing is now updated to
match config parsing of < 1.

It's tempting to add a MINIMUM_CLIENTS define, but... I didn't.

These changes were inspired by antirez#356, but this doesn't
fix that issue.

Matt Stancliff ee18135a19 Cluster: Fix trib create when masters==replicas
This bug was introduced in 2e5c394f during a refactor.

It took me a while to understand what was going on with
the code, so I've refactored it further by:
  - Replacing boolean values with meaningful symbols
  - Replacing 'i' with a meaningful variable name
  - Adding the proper abort check
  - Factoring out now duplicated conditionals
  - Adding optional verbose logging (we're inside *four*
    different looping constructs, so it takes a while to
    figure out where all the moving parts are)
  - Updating comment for the section

This fixes a problem when the number of master instances
equaled the number of replica instances.  Before, when
there were equal numbers of both, nodes_count would go to
zero, but the while loop would spin in i < @replicas because
i would never be updated (because the nodes_list of each ip
was length == 0, which triggered an endless loop of
next -> i = 0 -> 0 < 1? -> true -> next -> i = 0 ...)

Thanks to carlo who found this problem at:

Matt Stancliff a7478079a1 Cluster: remove variable causing warning
GCC-4.9 warned about this, but clang didn't.

This commit fixes warning:
sentinel.c: In function 'sentinelReceiveHelloMessages':

antirez 2dd8c46249 Sample and cache RSS in serverCron().
Obtaining the RSS (Resident Set Size) info is slow in Linux and OSX.
This slowed down the generation of the INFO 'memory' section.

Since the RSS does not require to be a real-time measurement, we
now sample it with server.hz frequency (10 times per second by default)
and use this value both to show the INFO rss field and to compute the
fragmentation ratio.

Practically this does not make any difference for memory profiling of
Redis but speeds up the INFO call significantly.
2014-03-24 12:03:41 +01:00
antirez ae211be98b sdscatvprintf(): Try to use a static buffer.
For small content the function now tries to use a static buffer to avoid
a malloc/free cycle that is too costly when the function is used in the
context of performance critical code path such as INFO output generation.

This change was verified to have positive effects in the execution speed
of the INFO command.
2014-03-24 10:23:55 +01:00
antirez 571d6b01de Cache uname() output across INFO calls.
Uname was profiled to be a slow syscall. It produces always the same
output in the context of a single execution of Redis, so calling it at
every INFO output generation does not make too much sense.

The uname utsname structure was modified as a static variable. At the
same time a static integer was added to check if we need to call uname
the first time.
2014-03-24 10:02:55 +01:00
antirez 06b2a389eb sdscatvprintf(): guess buflen using format length.
sdscatvprintf() uses a loop where it tries to output the formatted
string in a buffer of the initial length, if there was not enough room,
a buffer of doubled size is tried and so forth.

The initial guess for the buffer length was very poor, an hardcoded
"16". This caused the printf to be processed multiple times without a
good reason. Given that printf functions are already not fast, the
overhead was significant.

The new heuristic is to use a buffer 4 times the length of the format
buffer, and 32 as minimal size. This appears to be a good balance for
typical uses of the function inside the Redis code base.

This change improved INFO command performances 3 times.

antirez fd70c68c97 Add test-lru.rb to utils.
This is a program useful to evaluate the Redis LRU algorithm behavior.

antirez 24c350245d Use getLRUClock() instead of server.lruclock to create objects.
Thanks to Matt Stancliff for noticing this error. It was in the original
code but somehow I managed to remove the change from the commit...
2014-03-21 09:57:02 +01:00
antirez 7f274e3bfe The default maxmemory policy is now noeviction.
This is safer as by default maxmemory should just set a memory limit
without any key to be deleted, unless the policy is set to something
more relaxed.
2014-03-21 09:57:02 +01:00
antirez a219339ee0 Use 24 bits for the lru object field and improve resolution.
There were 2 spare bits inside the Redis object structure that are now
used in order to enlarge 4x the range of the LRU field.

At the same time the resolution was improved from 10 to 1 second: this
still provides 194 days before the LRU counter overflows (restarting from
zero).

This is not a problem since it only causes lack of eviction precision for
objects not touched for a very long time, and the lack of precision is
only temporary.

antirez fd5e8c0132 Use new dictGetRandomKeys() API to get samples for eviction.
The eviction quality degradates a bit in my tests, but since the API is

antirez 10c8d86242 struct dictEntry -> dictEntry. 2014-03-21 09:57:02 +01:00
antirez 26292670fa Added dictGetRandomKeys() to dict.c: mass get random entries.
This new function is useful to get a number of random entries from an
hash table when we just need to do some sampling without particularly
good distribution.

It just jumps at a random place of the hash table and returns the first
N items encountered by scanning linearly.

The main usefulness of this function is to speedup Redis internal
sampling of the key space, for example for key eviction or expiry.
2014-03-21 09:57:02 +01:00
antirez c641074a21 LRU eviction pool implementation.
This is an improvement over the previous eviction algorithm where we use
an eviction pool that is persistent across evictions of keys, and gets
populated with the best candidates for evictions found so far.

It allows to approximate LRU eviction at a given number of samples
better than the previous algorithm used.

antirez c9ac817cc0 Fix OBJECT IDLETIME return value converting to seconds.
estimateObjectIdleTime() returns a value in milliseconds now, so we need

2014-03-21 09:57:02 +01:00
antirez 205c2ccc0c Obtain LRU clock in a resolution dependent way.
For testing purposes it is handy to have a very high resolution of the
LRU clock, so that it is possible to experiment with scripts running in
just a few seconds how the eviction algorithms works.

This commit allows Redis to use the cached LRU clock, or a value
computed on demand, depending on the resolution. So normally we have the
good performance of a precomputed value, and a clock that wraps in many
days using the normal resolution, but if needed, changing a define will
switch behavior to an high resolution LRU clock.

2014-03-21 09:57:02 +01:00
antirez 9997b51ff8 Sentinel failure detection implementation improved.
Failure detection in Sentinel is ping-pong based. It used to work by
remembering the last time a valid PONG reply was received, and checking
if the reception time was too old compared to the current current time.

PINGs were sent at a fixed interval of 1 second.

This works in a decent way, but does not scale well when we want to set
very small values of "down-after-milliseconds" (this is the node
timeout basically).

This commit reiplements the failure detection making a number of
changes. Some changes are inspired to Redis Cluster failure detection
code:

* A new last_ping_time field is added in representation of instances.
  If non zero, we have an active ping that was sent at the specified
  time. When a valid reply to ping is received, the field is zeroed
  again.
* last_ping_time is not reset when we reconnect the link or send a new
  ping, so from our point of view it represents the time we started
  waiting for the instance to reply to our pings without receiving a
  reply.
* last_ping_time is now used in order to check if the instance is
  timed out. This means that we can have a node timeout of 100
  milliseconds and yet the system will work well since the new check is
  not bound to the period used to send pings.
* Pings are now sent every second, or often if the value of
  down-after-milliseconds is less than one second. With a lower limit of
  10 HZ ping frequency.
* Link reconnection code was improved. This is used in order to try to
  reconnect the link when we are at 50% of the node timeout without a
  valid reply received yet. However the old code triggered unnecessary
  reconnections when the node timeout was very small. Now that should be
  ok.

The new code passes the tests but more testing is needed and more unit
tests stressing the failure detector, so currently this is merged only
in the unstable branch.

Matt Stancliff 0c8f0079f9 Fix segfault from accessing array out of bounds
argc == 2; argv[2] == crash
2014-03-14 22:57:29 +01:00
antirez 668a95a583 Sentinel: be safe under crash-recovery assumptions.
Sentinel's main safety argument is that there are no two configurations
for the same master with the same version (configuration epoch).

For this to be true Sentinels require to be authorized by a majority.
Additionally Sentinels require to do two important things:

* Never vote again for the same epoch.
* Never exchange an old vote for a fresh one.

The first prerequisite, in a crash-recovery system model, requires to
persist the master->leader_epoch on durable storage before to reply to
messages. This was not the case.

We also make sure to persist the current epoch in order to never reply
to stale votes requests from other Sentinels, after a recovery.

The configuration is persisted by making use of fsync(), this is
considered in the context of this code a good enough guarantee that
after a restart our durable state is restored, however this may not
always be the case depending on the kind of hardware and operating
system used.

antirez ca2a3b3240 Sentinel: fake PUBLISH command to receive HELLO messages.
Now the way HELLO messages are received is unified.
Now it is no longer needed for Sentinels to converge to the higher
configuration for a master to be able to chat via some Redis instance,
the are able to directly exchanges configurations.

Note that this commit does not include the (trivial) change needed to
send HELLO messages to Sentinel instances as well, since for an error I
committed the change in the previous commit that refactored hello
messages processing into a separated function.

antirez 48702e0011 Cluster: set slot error if we receive an update for a busy slot.
By manually modifying nodes configurations in random ways, it is possible
to create the following scenario:

A is serving keys for slot 10
B is manually configured to serve keys for slot 10

A receives an update from B (or another node) where it is informed that
the slot 10 is now claimed by B with a greater configuration epoch,
however A still has keys from slot 10.

With this commit A will put the slot in error setting it in IMPORTING
state, so that redis-trib can detect the issue.

antirez 01eee56f4f DEBUG ERROR implemented.
The new "error" subcommand of the DEBUG command can reply with an user
selected error, specified as its sole argument:

    DEBUG ERROR "LOADING please wait..."

The error is generated just prefixing the command argument with a "-"
character, and replacing newlines with spaces (since error replies can't
include newlines).

The goal of the command is to help in Client libraries unit tests by
making simple to simulate a command call triggering a given error.

antirez 81efa0d296 Cluster: evalGetKey() added for EVAL/EVALSHA.
Previously we used zunionInterGetKeys(), however after this function was
fixed to account for the destination key (not needed when the API was

antirez a2a72b87e0 Cluster: getKeysFromCommand() API cleaned up.
This API originated from the "diskstore" experiment, not for Redis

that need to be fetched from disk (preloaded).

All useless with Cluster, so removed with the result of code
simplification.

antirez 3119f4f694 Cluster: better timeout and retry time for failover.
When node-timeout is too small, in the order of a few milliseconds,
there is no way the voting process can terminate during that time, so we

The retry time is set to two times the failover timeout time, so it is
at least 4 seconds.

Matt Stancliff a0ea8f235e Cluster: error out quicker if port is unusable

Matt Stancliff 6f4b5ef6d5 Fix "can't bind to address" error reporting.
Report the actual port used for the listening attempt instead of
server.port.

Originally, Redis would just listen on server.port.
But, with clustering, Redis uses a Cluster Port too,
so we can't say server.port is always where we are listening.

If you tried to launch Redis with a too-high port number (any
port where Port+10000 > 65535), Redis would refuse to start, but
only print an error saying it can't connect to the Redis port.

antirez ef4e465316 Sentinel test: set less time sensitive defaults.
This commit sets the failover timeout to 30 seconds instead of the 180
seconds default, and allows to reconfigure multiple slaves at the same
time.

This makes tests less sensible to timing, with the result that there are
less false positives due to normal behaviors that require time to
succeed or to be retried.

However the long term solution is probably some way in order to detect
when a test failed because of timing issues (for example split brain
during leader election) and retry it.
2014-03-05 10:22:07 +01:00
antirez 313f8831ed Sentinel: more aggressive failover start desynchronization.
Sentinel needs to avoid split brain conditions due to multiple sentinels
trying to get voted at the exact same time.

So far some desynchronization was provided by fluctuating server.hz,
that is the frequency of the timer function call. However the
desynchonization provided in this way was not enough when using many
Sentinel instances, especially when a large quorum value is used in
order to force a greater degree of agreement (more than N/2+1).

It was verified that it was likely to trigger a split brain
condition, forcing the system to try again after a timeout.
Usually the system will succeed after a few retries, but this is not
optimal.

This commit desynchronizes instances in a more effective way to make it
likely that the first attempt will be successful.

antirez e4833ed8bf Fix configEpoch assignment when a cluster slot gets "closed".
This is still code to rework in order to use agreement to obtain a new
configEpoch when a slot is migrated, however this commit handles the
special case that happens when the nodes are just started and everybody
has a configEpoch of 0. In this special condition to have the maximum
configEpoch is not enough as the special epoch 0 is not unique (all the
others are).

This does not fixes the intrinsic race condition of a failover happening
while we are resharding, that will be addressed later.

Matt Stancliff 7c092b679f Force INFO used_memory_peak to match peak memory
used_memory_peak only updates in serverCron every server.hz,
but Redis can use more memory and a user can request memory
INFO before used_memory_peak gets updated in the next
cron run.

This patch updates used_memory_peak to the current
memory usage if the current memory usage is higher
than the recorded used_memory_peak value.

(And it only calls zmalloc_used_memory() once instead of
twice as it was doing before.)

antirez 9104f1e672 warnigns -> warnings in redisBitpos(). 2014-02-27 15:52:43 +01:00
antirez eacc0951a2 More consistent BITPOS behavior with bit=0 and ranges.
With the new behavior it is possible to specify just the start in the
range (the end will be assumed to be the first byte), or it is possible
to specify both start and end.

This is useful to change the behavior of the command when looking for
zeros inside a string.

1) If the user specifies both start and end, and no 0 is found inside
   the range, the command returns -1.

2) If instead no range is specified, or just the start is given, even
   if in the actual string no 0 bit is found, the command returns the
   first bit on the right after the end of the string.

So for example if the string stored at key foo is "\xff\xff":

    BITPOS foo (returns 16)
    BITPOS foo 0 -1 (returns -1)
    BITPOS foo 0 (returns 16)

The idea is that when no end is given the user is just looking for the
first bit that is zero and can be set to 1 with SETBIT, as it is
"available". Instead when a specific range is given, we just look for a
zero within the boundaries of the range.

This error was conceived for the older version of Sentinel that worked

slaves.

This reply does not make sense today, every Sentinel should reply with
the best information it has currently. The error will make even more
sense in the future since the plan is to allow Sentinels to update the
configuration of other Sentinels via gossip with a direct chat without
the prerequisite that they have at least a monitored instance in common.

antirez 3c1672da7d Update cached time in rdbLoad() callback.
server.unixtime and server.mstime are cached less precise timestamps
that we use every time we don't need an accurate time representation and
a syscall would be too slow for the number of calls we require.

Such an example is the initialization and update process of the last
interaction time with the client, that is used for timeouts.

However rdbLoad() can take some time to load the DB, but at the same
time it did not updated the time during DB loading. This resulted in the
bug described in issue #1535, where in the replication process the slave
loads the DB, creates the redisClient representation of its master, but
the timestamp is so old that the master, under certain conditions, is
sensed as already "timed out".

Thanks to @yoav-steinberg and Redis Labs Inc for the bug report and
analysis.

antirez 14143fbede Fix script cache bug in the scripting engine.
This commit fixes a serious Lua scripting replication issue, described
by Github issue #1549. The root cause of the problem is that scripts
were put inside the script cache, assuming that slaves and AOF already
contained it, even if the scripts sometimes produced no changes in the
data set, and were not actaully propagated to AOF/slaves.

Example:

    eval "if tonumber(KEYS[1]) > 0 then redis.call('incr', 'x') end" 1 0

Then:

    evalsha <sha1 step 1 script> 1 0

At this step sha1 of the script is added to the replication script cache
(the script is marked as known to the slaves) and EVALSHA command is
transformed to EVAL. However it is not dirty (there is no changes to db),
so it is not propagated to the slaves. Then the script is called again:

    evalsha <sha1 step 1 script> 1 1

At this step master checks that the script already exists in the
replication script cache and doesn't transform it to EVAL command. It is
dirty and propagated to the slaves, but they fail to evaluate the script
as they don't have it in the script cache.

The fix is trivial and just uses the new API to force the propagation of
the executed command regardless of the dirty state of the data set.

Thank you to @minus-infinity on Github for finding the issue,
understanding the root cause, and fixing it.

For fsync == always we still abort on errors since there is currently no

antirez 2e3f6b0fb3 Cluster: on resharding upgrade version of receiving node.
The node receiving the hash slot needs to have a version that wins over
the other versions in order to force the ownership of the slot.

However the current code is far from perfect since a failover can happen
during the manual resharding. The fix is a work in progress but the
bottom line is that the new version must either be voted as usually,
set by redis-trib manually after it makes sure can't be used by other
nodes, or reserved configEpochs could be used for manual operations (for
example odd versions could be never used by slaves and are always used
by CLUSTER SETSLOT NODE).

antirez a221ae5ce2 Cluster: fsync at every SETSLOT command puts too pressure on disks.
During slots migration redis-trib can send a number of SETSLOT commands.
Fsyncing every time is a bit too much in production as verified
empirically.

To make sure configs are fsynced on all nodes after a resharding
redis-trib may send something like CLUSTER CONFSYNC.

In this case fsyncs were not providing too much value since anyway
processes can crash in the middle of the resharding of an hash slot, and
redis-trib should be able to recover from this condition anyway.

If the slot is manually assigned to another node, clear the migrating
status regardless of the fact it was previously assigned to us or not,
as long as we no longer have keys for this slot.

This avoid a race during slots migration that may leave the slot in
migrating status in the source node, since it received an update message
from the destination node that is already claiming the slot.

This way we are sure that redis-trib at the end of the slot migration is
always able to close the slot correctly.

antirez fa6f4f21c3 Cluster: ignore slot config changes if we are importing it. 2014-02-11 00:38:59 +01:00
antirez 30214fff3e Cluster: update configEpoch after manually messing with slots. 2014-02-11 00:38:56 +01:00
antirez cfcb09bf76 Cluster: redis-trib, more info about open slots error. 2014-02-11 00:38:53 +01:00
antirez 8e12fae05e Cluster: fixed inverted arguments in logging function call. 2014-02-10 17:21:17 +01:00
antirez 6a01545744 Cluster: clear the FAIL status for masters without slots.
Masters without slots don't participate to the cluster but just do
redirections, no need to take them in FAIL state if they are back
reachable.
2014-02-10 17:19:16 +01:00
antirez 969a4f1db3 Cluster: replica migration should only work for masters serving slots. 2014-02-10 17:08:47 +01:00
antirez cb92a1ef08 Cluster: redis-trib del-node variable typo fixed. 2014-02-10 16:59:17 +01:00
antirez 6987a95952 Cluster: clusterReadHandler() fixed to work with new message header. 2014-02-10 16:28:44 +01:00
antirez ad85f520f8 Cluster: don't propagate PUBLISH two times.
PUBLISH both published messages via Cluster bus and replication when
cluster was enabled, resulting in duplicated message in the slave.
2014-02-10 16:05:26 +01:00
antirez b82b66b51d Cluster: signature changed to "RCmb" (Redis Cluster message bus).
Sounds better after all.

Contributor Covenant Code of Conduct
Our Pledge
We as members, contributors, and leaders pledge to make participation in our
community a harassment-free experience for everyone, regardless of age, body
size, visible or invisible disability, ethnicity, sex characteristics, gender
identity and expression, level of experience, education, socio-economic status,
nationality, personal appearance, race, religion, or sexual identity
and orientation.
We pledge to act and interact in ways that contribute to an open, welcoming,
diverse, inclusive, and healthy community.
Our Standards
Examples of behavior that contributes to a positive environment for our
community include:
* Demonstrating empathy and kindness toward other people
* Being respectful of differing opinions, viewpoints, and experiences
* Giving and gracefully accepting constructive feedback
* Accepting responsibility and apologizing to those affected by our mistakes,
and learning from the experience
* Focusing on what is best not just for us as individuals, but for the
overall community
Examples of unacceptable behavior include:
* The use of sexualized language or imagery, and sexual attention or
advances of any kind
* Trolling, insulting or derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or email
address, without their explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
Enforcement Responsibilities
Community leaders are responsible for clarifying and enforcing our standards of
acceptable behavior and will take appropriate and fair corrective action in
response to any behavior that they deem inappropriate, threatening, offensive,
or harmful.
Community leaders have the right and responsibility to remove, edit, or reject
comments, commits, code, wiki edits, issues, and other contributions that are
not aligned to this Code of Conduct, and will communicate reasons for moderation
decisions when appropriate.
Scope
This Code of Conduct applies within all community spaces, and also applies when
an individual is officially representing the community in public spaces.
Examples of representing our community include using an official e-mail address,
posting via an official social media account, or acting as an appointed
representative at an online or offline event.
Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported to the community leaders responsible for enforcement at
this email address: redis@redis.io.
All complaints will be reviewed and investigated promptly and fairly.
All community leaders are obligated to respect the privacy and security of the
reporter of any incident.
Enforcement Guidelines
Community leaders will follow these Community Impact Guidelines in determining
the consequences for any action they deem in violation of this Code of Conduct:
1. Correction
Community Impact: Use of inappropriate language or other behavior deemed
unprofessional or unwelcome in the community.
Consequence: A private, written warning from community leaders, providing
clarity around the nature of the violation and an explanation of why the
behavior was inappropriate. A public apology may be requested.
2. Warning
Community Impact: A violation through a single incident or series
of actions.
Consequence: A warning with consequences for continued behavior. No
interaction with the people involved, including unsolicited interaction with
those enforcing the Code of Conduct, for a specified period of time. This
includes avoiding interactions in community spaces as well as external channels
like social media. Violating these terms may lead to a temporary or
permanent ban.
3. Temporary Ban
Community Impact: A serious violation of community standards, including
sustained inappropriate behavior.
Consequence: A temporary ban from any sort of interaction or public
communication with the community for a specified period of time. No public or
private interaction with the people involved, including unsolicited interaction
with those enforcing the Code of Conduct, is allowed during this period.
Violating these terms may lead to a permanent ban.
4. Permanent Ban
Community Impact: Demonstrating a pattern of violation of community
standards, including sustained inappropriate behavior, harassment of an
individual, or aggression toward or disparagement of classes of individuals.
Consequence: A permanent ban from any sort of public interaction within
the community.
Attribution
This Code of Conduct is adapted from the Contributor Covenant,
version 2.0, available at
https://www.contributor-covenant.org/version/2/0/code_of_conduct.html.
Community Impact Guidelines were inspired by Mozilla's code of conduct
enforcement ladder.
For answers to common questions about this code of conduct, see the FAQ at
https://www.contributor-covenant.org/faq. Translations are available at
https://www.contributor-covenant.org/translations.

# IMPORTANT: HOW TO USE REDIS GITHUB ISSUES
* Github issues SHOULD ONLY BE USED to report bugs, and for DETAILED feature
requests. Everything else belongs to the Redis Google Group.
PLEASE DO NOT POST GENERAL QUESTIONS that are not about bugs or suspected
bugs in the Github issues system. We'll be very happy to help you and provide
all the support Reddit sub:
http://reddit.com/r/redis
There is also an active community of Redis users at Stack Overflow:
http://stackoverflow.com/questions/tagged/redis
# How to provide a patch for a new feature
1. If it is a major feature or a semantical change, please post it as a new submission in r/redis on Reddit at http://reddit.com/r/redis. Try to be passionate about why the feature is needed, make users upvote your proposal to gain traction and so forth. Read feedbacks about the community. But in this first step **please don't write code yet**.
2. If in step 1 you get an acknowledge from the project leaders, use the
following procedure to submit a patch:
a. Fork Redis on github ( http://help.github.com/fork-a-repo/ )
b. Create a topic branch (git checkout -b my_branch)
c. Push to your branch (git push origin my_branch)
d. Initiate a pull request on github ( http://help.github.com/send-pull-requests/ )
e. Done :)
For minor fixes just open a pull request on Github.
Thanks!

# IMPORTANT: HOW TO USE REDIS GITHUB ISSUES
GitHub issues SHOULD ONLY BE USED to report bugs and for DETAILED feature
requests. Everything else should be asked on Discord:
https://discord.com/invite/redis
PLEASE DO NOT POST GENERAL QUESTIONS that are not about bugs or suspected
bugs in the GitHub issues system. We'll be delighted to help you and provide
all the support on Discord.
There is also an active community of Redis users at Stack Overflow:
https://stackoverflow.com/questions/tagged/redis
Issues and pull requests for documentation belong on the redis-doc repo:
https://github.com/redis/redis-doc
If you are reporting a security bug or vulnerability, see SECURITY.md.
# How to provide a patch for a new feature
1. If it is a major feature or a semantical change, please don't start coding
straight away: if your feature is not a conceptual fit you'll lose a lot of
time writing the code without any reason. Start by posting in the mailing list
and creating an issue at Github with the description of, exactly, what you want
to accomplish and why. Use cases are important for features to be accepted.
Here you can see if there is consensus about your idea.
2. If in step 1 you get an acknowledgment from the project leaders, use the
following procedure to submit a patch:
a. Fork Redis on GitHub ( https://docs.github.com/en/github/getting-started-with-github/fork-a-repo )
b. Create a topic branch (git checkout -b my_branch)
c. Push to your branch (git push origin my_branch)
d. Initiate a pull request on GitHub ( https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request )
e. Done :)
3. Keep in mind that we are very overloaded, so issues and PRs sometimes wait
for a *very* long time. However this is not a lack of interest, as the project
gets more and more users, we find ourselves in a constant need to prioritize
certain issues/PRs over others. If you think your issue/PR is very important
try to popularize it, have other users commenting and sharing their point of
view, and so forth. This helps.
4. For minor fixes - open a pull request on GitHub.

higher order protocols and features: Redis Cluster and the upcoming
Redis Proxy are our main goals. A shared nothing approach is not just
much simpler (see the previous point in this document), is also optimal
in NUMA systems. In the specific case of Redis it allows for each instance

Where to find complete Redis documentation?
-------------------------------------------
This README is just a fast "quick start" document. You can find more detailed
documentation at http://redis.io
Building Redis
--------------
Redis can be compiled and used on Linux, OSX, OpenBSD, NetBSD, FreeBSD.
We support big endian and little endian architectures.
It may compile on Solaris derived systems (for instance SmartOS) but our
support for this platform is "best effort" and Redis is not guaranteed to
work as well as in Linux, OSX, and *BSD there.
It is as simple as:
% make
You can run a 32 bit Redis binary using:
% make 32bit
After building Redis is a good idea to test it, using:
% make test
Fixing build problems with dependencies or cached build options
—--------
Redis has some dependencies which are included into the "deps" directory.
"make" does not rebuild dependencies automatically, even if something in the
source code of dependencies is changes.
When you update the source code with `git pull` or when code inside the
dependencies tree is modified in any other way, make sure to use the following
command in order to really clean everything and rebuild from scratch:
make distclean
This will clean: jemalloc, lua, hiredis, linenoise.
Also if you force certain build options like 32bit target, no C compiler
optimizations (for debugging purposes), and other similar build time options,
those options are cached indefinitely until you issue a "make distclean"
command.
Fixing problems building 32 bit binaries
---------
If after building Redis with a 32 bit target you need to rebuild it
with a 64 bit target, or the other way around, you need to perform a
"make distclean" in the root directory of the Redis distribution.
In case of build errors when trying to build a 32 bit binary of Redis, try
the following steps:
* Install the packages libc6-dev-i386 (also try g++-multilib).
* Try using the following command line instead of "make 32bit":
make CFLAGS="-m32 -march=native" LDFLAGS="-m32"
Allocator
---------
Selecting a non-default memory allocator when building Redis is done by setting
the `MALLOC` environment variable. Redis is compiled and linked against libc
malloc by default, with the exception of jemalloc being the default on Linux
systems. This default was picked because jemalloc has proven to have fewer
fragmentation problems than libc malloc.
To force compiling against libc malloc, use:
% make MALLOC=libc
To compile against jemalloc on Mac OS X systems, use:
% make MALLOC=jemalloc
Verbose build
-------------
Redis will build with a user friendly colorized output by default.
If you want to see a more verbose output use the following:
% make V=1
Running Redis
-------------
To run Redis with the default configuration just type:
% cd src
% ./redis-server
If you want to provide your redis.conf, you have to run it using an additional
parameter (the path of the configuration file):
% cd src
% ./redis-server /path/to/redis.conf
It is possible to alter the Redis configuration passing parameters directly
as options using the command line. Examples:
% ./redis-server --port 9999 --slaveof 127.0.0.1 6379
% ./redis-server /etc/redis/6379.conf --loglevel debug
All the options in redis.conf are also supported as options using the command
line, with exactly the same name.
Playing with Redis
------------------
You can use redis-cli to play with Redis. Start a redis-server instance,
then in another terminal try the following:
% cd src
% ./redis-cli
redis> ping
PONG
redis> set foo bar
OK
redis> get foo
"bar"
redis> incr mycounter
(integer) 1
redis> incr mycounter
(integer) 2
redis>
You can find the list of all the available commands here:
http://redis.io/commands
Installing Redis
-----------------
In order to install Redis binaries into /usr/local/bin just use:
% make install
You can use "make PREFIX=/some/other/directory install" if you wish to use a
different destination.
Make install will just install binaries in your system, but will not configure
init scripts and configuration files in the appropriate place. This is not
needed if you want just to play a bit with Redis, but if you are installing
it the proper way for a production system, we have a script doing this
for Ubuntu and Debian systems:
% cd utils
% ./install_server.sh
The script will ask you a few questions and will setup everything you need
to run Redis properly as a background daemon that will start again on
system reboots.
You'll be able to stop and start Redis using the script named
/etc/init.d/redis_<portnumber>, for instance /etc/init.d/redis_6379.

This README is just a fast *quick start* document. You can find more detailed documentation at [redis.io](https://redis.io).
### What is Redis?
For developers, who are building real-time data-driven applications, Redis is the preferred, fastest, and most feature-rich cache, data structure server, and document and vector query engine.
Redis covers a wide range of use cases across a wide range of industries and projects, serving as
- **A cache**, supporting multiple key eviction policies, key expiration, and hash-field expiration
- **A distributed session store**, supporting multiple session data modeling options (string, JSON, hash).
- **A data structure server**: low-level data structures (string, JSON, list, hash, set, sorted set, bitmap, bitfield, and more - see full list below) with high-level semantics (counter, stack, queue, priority queue, rate limiter, leaderboard, ...), and with transactions and scripting support.
- **A NoSQL data store**: key-value, document, and time series.
- **A secondary index and a search and query engine**: with Redis Query Engine users can define indexes for hash and JSON documents, and use a rich query language for vector search, full-text search, geospatial queries, ranking, and aggregations.
- **A distributed event store, stream-processing platform, and message broker**: queue (list), priority queue (sorted set), event deduplication (set), streams, and pub/sub, with probabilistic stream processing capabilities.
- **A vector store**, integrated with GenAI applications and ecosystems (e.g., LangGraph, mem0), providing short-term memory (checkpointers), long-term memory (store), LLM response caching (LLM semantic cache), and context retrieval (RAG applications).
- **Real time analytics**, including personalization, recommendations, fraud and anomaly detection, and risk assessment.
Redis can be relied upon (it is robust and has a well-defined behavior), it comes with a long-term commitment (we keep maintaining Redis, avoid introducing breaking changes, and keep it innovative and competitive). Redis is fast and has a low memory footprint (with the right tradeoffs), easy to understand, learn, and use, and easy to adopt across a wide range of development environments and languages.
If you want to know more, here is a list of starting points:
- Introduction to Redis data types - https://redis.io/docs/latest/develop/data-types/
- The full list of Redis commands - https://redis.io/commands
- Redis for AI - https://redis.io/docs/latest/develop/ai/
- and much more - https://redis.io/documentation
### What is Redis Open Source?
Redis Community Edition (Redis CE) was renamed Redis Open Source with the v8.0 release.
Redis Ltd. also offers [Redis Software](https://redis.io/enterprise/), a self-managed software with additional compliance, reliability, and resiliency for enterprise scaling,
and [Redis Cloud](https://redis.io/cloud/), a fully managed service integrated with Google Cloud, Azure, and AWS for production-ready apps.
Read more about the differences between Redis Open Source and Redis [here](https://redis.io/technology/advantages/).
### Redis Open Source - binary distributions
The fastest way to deploy Redis is using one the binary distributions:
- Alpine and Debian Docker images - https://hub.docker.com/_/redis
- Install using snap - see https://github.com/redis/redis-snap
- Install using brew - see https://github.com/redis/homebrew-redis
- Install using RPM - see https://github.com/redis/redis-rpm
- Install using Debian APT - see https://github.com/redis/redis-debian
If you prefer to build Redis from source - see instructions below.
### Using Redis with redis-cli
`redis-cli` is Redis' command line interface. It is available as part of all the binary distributions and when you build Redis from source.
See https://redis.io/docs/latest/develop/tools/cli/
You can start a redis-server instance, and then, in another terminal try the following:
```
% cd src
% ./redis-cli
redis> ping
PONG
redis> set foo bar
OK
redis> get foo
"bar"
redis> incr mycounter
(integer) 1
redis> incr mycounter
(integer) 2
redis>
```
### Using Redis with Redis Insight
For a more visual and user-friendly experience, use Redis Insight - a tool that lets you explore data, design, develop, and optimize your applications while also serving as a platform for Redis education and onboarding. Redis Insight integrates Redis Copilot, a natural language AI assistant that improves the experience when working with data and commands.
See https://redis.io/docs/latest/develop/tools/insight/ and https://github.com/RedisInsight/RedisInsight.
### Using Redis with client libraries
To connect your application to Redis, you will need a client library. The list of client libraries is available in https://redis.io/docs/latest/develop/clients/.
### Redis Data types, processing engines, and capabilities
Redis provides a variety of data types, processing engines, and capabilities to support a wide range of use cases:
1. **String**
- Strings store sequences of bytes, including text, serialized objects, and binary arrays. As such, strings are the simplest type of value you can associate with a Redis key.
- [Documentation: Strings](https://redis.io/docs/latest/develop/data-types/strings)
1. **JSON** (*)
- The JSON data type provides JavaScript Object Notation (JSON) support for Redis. It lets you store, retrieve, and update JSON documents. A JSON document can be queried and manipulated using JSONPath expressions. JSON also works seamlessly with the Redis Query Engine to let you index and query JSON documents.
- [Documentation: JSON quick start](https://redis.io/docs/latest/develop/data-types/json/#use-redisjson)
1. **Hash**
- A hash is a collection of fields, each field is a name-value string pair. You can use hashes to represent flat objects and to store groupings of counters, among other things. Expiration time or a time-to-live can be set for each hash field.
- [Documentation: Hashes](https://redis.io/docs/latest/develop/data-types/hashes)
1. **Redis Query Engine** (*)
- The Redis Query Engine allows you to use Redis as a document database, a vector database, a secondary index, and a search engine. With Redis Query Engine, users can define indexes for hash and JSON documents, and use a rich query language for vector search, full-text search, geospatial queries, and aggregations.
- [Documentation: Redis Query Engine](https://redis.io/docs/latest/develop/interact/search-and-query/)
1. **List**
- A list is a list of strings, sorted by insertion order. They are great for stacks, queues, and for queue management and worker systems.
- [Documentation: Lists](https://redis.io/docs/latest/develop/data-types/lists)
1. **Set**
- A set is an unordered collection of unique strings (members). Sets can be used to track unique items (e.g., track all unique IP addresses accessing a given blog post), represent relations (e.g., the set of all users with a given role). Redis also supports common set operations such as intersection, unions, and differences.
- [Documentation: Sets](https://redis.io/docs/latest/develop/data-types/sets)
1. **Sorted Set**
- A sorted set is similar to a set, but each member is associated with a score. When more than one member has the same score, the members are ordered lexicographically. Some use cases for sorted sets include leaderboards and sliding-window rate limiters.
- [Documentation: Sorted Sets](https://redis.io/docs/latest/develop/data-types/sorted-sets)
1. **Vector Set** (beta)
- Vector set is a data type similar to a sorted set, but instead of a score, each member is associated with a vector embedding. You can add items to a vector set, and then retrieve the members that are the most similar to a specified vector embedding, or to the vector embedding of an existing member.
- [Documentation: Vector sets](https://redis.io/docs/latest/develop/data-types/vector-sets)
1. **Geospatial Index**
- Geospatial indexes let you store coordinates and search for them. This data structure is useful for finding nearby points within a given radius or bounding box.
- [Documentation: Geo](https://redis.io/docs/latest/develop/data-types/geospatial/)
1. **Bitmap**
- Bitmaps provide bit-oriented operations on a bit vector. You can get bits, set bits, and perform bitwise operations between bitmaps. Bitmaps are often used for efficient management of memberships or permissions, where each bit represents a particular member.
- [Documentation: Bitmap](https://redis.io/docs/latest/develop/data-types/bitmaps/)
1. **Bitfield**
- Bitfields let you set, increment, and get integer values of arbitrary bit length - from unsigned 1-bit integers to signed 63-bit integers. Bitfields are often used for efficient management of arrays of limited-range counters or numerical values.
- [Documentation: Bitfield](https://redis.io/docs/latest/develop/data-types/bitfields/)
1. **HyperLogLog**
- HyperLogLog is a probabilistic data structure used for approximating the cardinality of a stream (i.e., the number of unique elements).
- [Documentation: HyperLogLog](https://redis.io/docs/latest/develop/data-types/hyperloglogs)
1. **Bloom filter** (*)
- Bloom filter is a probabilistic data structure used for checking if a given value is present in a stream.
- [Documentation: Bloom filter](https://redis.io/docs/latest/develop/data-types/probabilistic/bloom-filter/)
1. **Cuckoo filter** (*)
- Cuckoo filter, just like Bloom filter, is a probabilistic data structure for checking if a given value is present in a stream, while also allowing limited counting and deletions.
- [Documentation: Cuckoo filter](https://redis.io/docs/latest/develop/data-types/probabilistic/cuckoo-filter/)
1. **Top-k** (*)
- Top-k is a probabilistic data structure used for tracking the most frequent values in a data stream.
- [Documentation: Top-k](https://redis.io/docs/latest/develop/data-types/probabilistic/top-k/)
1. **Count-min sketch** (*)
- Count-Min Sketch is a probabilistic data structure used for estimating how many times a given value appears in the data stream.
- [Documentation: Count-min sketch](https://redis.io/docs/latest/develop/data-types/probabilistic/count-min-sketch/)
1. **t-digest** (*)
- t-digest is a probabilistic data structure used for estimating which fraction / how many values in a data stream are smaller than a given value, which value is smaller than p percent of the values in a data stream, or what are the smallest/largest values in the data stream.
- [Documentation: t-digeset](https://redis.io/docs/latest/develop/data-types/probabilistic/t-digest/)
1. **Time series** (*)
- a time series allows storing and querying timetagged data points (samples).
- [Documentation: Time series quick start](https://redis.io/docs/latest/develop/data-types/timeseries/quickstart/)
1. **Pub/Sub**
- Pub/Sub (short for publish/subscribe) is a lightweight messaging capability. Publishers send messages to a channel, and subscribers receive messages from that channel.
- [Documentation: Redis streams](https://redis.io/docs/latest/develop/interact/pubsub/)
1. **Stream**
- A stream is a data structure that acts like an append-only log. Each stream entry consists of name-value string pairs, similar to a hash. Streams support multiple consumption strategies, where consumers can pop entries, consume entries by range, or listen to entries. Consumer groups allow multiple workers to retrieve different stream entries in order to scale message processing.
- [Documentation: Redis streams](https://redis.io/docs/latest/develop/data-types/streams/)
1. **Transactions**
- A transaction allows the execution of a group of commands in a single step. A request sent by another client will never be served in the middle of the execution of a transaction. This guarantees that the commands are executed as a single isolated operation.
- [Documentation: Transactions](https://redis.io/docs/latest/develop/interact/transactions/)
1. **Programmability**
- Users can upload and execute Lua scripts on the server. Scripts can employ programmatic control structures and use most of the commands while executing to access the database. Because scripts are executed on the server, reading and writing data from scripts is very efficient. Functions provide the same core functionality as scripts but are first-class software artifacts of the database. Redis manages functions as an integral part of the database and ensures their availability via data persistence and replication.
- [Documentation: Scripting with Lua](https://redis.io/docs/latest/develop/interact/programmability/eval-intro/)
- [Documentation: Functions](https://redis.io/docs/latest/develop/interact/programmability/functions-intro/)

### Build and run Redis with all data structures - macOS 15 (Sequoia)
Support and instructions will be provided at a later date.
### Building Redis - flags and general notes
Redis can be compiled and used on Linux, OSX, OpenBSD, NetBSD, FreeBSD.
We support big endian and little endian architectures, and both 32 bit and 64 bit systems.
It may compile on Solaris derived systems (for instance SmartOS) but our support for this platform is *best effort* and Redis is not guaranteed to work as well as in Linux, OSX, and \*BSD.
To build Redis with all the data structures (including JSON, time series, Bloom filter, cuckoo filter, count-min sketch, top-k, and t-digest) and with Redis Query Engine, make sure first that all the prerequisites are installed (see build instructions above, per operating system). You need to use the following flag in the make command:
```
make BUILD_WITH_MODULES=yes
```
To build Redis with just the core data structures, use:
```
make
```
To build with TLS support, you need OpenSSL development libraries (e.g. libssl-dev on Debian/Ubuntu) and the following flag in the make command:
```
make BUILD_TLS=yes
```
To build with systemd support, you need systemd development libraries (such as libsystemd-dev on Debian/Ubuntu or systemd-devel on CentOS), and the following flag:
```
make USE_SYSTEMD=yes
```
To append a suffix to Redis program names, add the following flag:
```
make PROG_SUFFIX="-alt"
```
You can build a 32 bit Redis binary using:
```
make 32bit
```
After building Redis, it is a good idea to test it using:
```
make test
```
If TLS is built, running the tests with TLS enabled (you will need `tcl-tls` installed):
```
./utils/gen-test-certs.sh
./runtest --tls
```
### Fixing build problems with dependencies or cached build options
Redis has some dependencies which are included in the `deps` directory. `make` does not automatically rebuild dependencies even if something in the source code of dependencies changes.
When you update the source code with `git pull` or when code inside the dependencies tree is modified in any other way, make sure to use the following command in order to really clean everything and rebuild from scratch:
```
make distclean
```
This will clean: jemalloc, lua, hiredis, linenoise and other dependencies.
Also if you force certain build options like 32bit target, no C compiler optimizations (for debugging purposes), and other similar build time options, those options are cached indefinitely until you issue a `make distclean`
command.
### Fixing problems building 32 bit binaries
If after building Redis with a 32 bit target you need to rebuild it
with a 64 bit target, or the other way around, you need to perform a `make distclean` in the root directory of the Redis distribution.
In case of build errors when trying to build a 32 bit binary of Redis, try the following steps:
* Install the package libc6-dev-i386 (also try g++-multilib).
* Try using the following command line instead of `make 32bit`:
`make CFLAGS="-m32 -march=native" LDFLAGS="-m32"`
### Allocator
Selecting a non-default memory allocator when building Redis is done by setting the `MALLOC` environment variable. Redis is compiled and linked against libc malloc by default, with the exception of jemalloc being the default on Linux systems. This default was picked because jemalloc has proven to have fewer fragmentation problems than libc malloc.
To force compiling against libc malloc, use:
```
make MALLOC=libc
```
To compile against jemalloc on Mac OS X systems, use:
```
make MALLOC=jemalloc
```
### Monotonic clock
By default, Redis will build using the POSIX clock_gettime function as the monotonic clock source. On most modern systems, the internal processor clock can be used to improve performance. Cautions can be found here: http://oliveryang.net/2015/09/pitfalls-of-TSC-usage/
To build with support for the processor's internal instruction clock, use:
```
make CFLAGS="-DUSE_PROCESSOR_CLOCK"
```
### Verbose build
Redis will build with a user-friendly colorized output by default.
If you want to see a more verbose output, use the following:
```
make V=1
```

# Security Policy
## Supported Versions
Redis is generally backward compatible with very few exceptions, so we
recommend users to always use the latest version to experience stability,
performance and security.
We generally backport security issues to a single previous major version,
unless this is not possible or feasible with a reasonable effort.
| Version | Supported |
|---------|-------------------------------------------------------------|
| 8.0.x | :white_check_mark: |
| 7.4.x | :white_check_mark: |
| 7.2.x | :white_check_mark: |
| < 7.2.x | :x: |
| 6.2.x | :white_check_mark: Support may be removed after end of 2025 |
| < 6.2.x | :x: |
## Reporting a Vulnerability
If you believe you've discovered a serious vulnerability, please contact the
Redis core team at redis@redis.io. We will evaluate your report and if
necessary issue a fix and an advisory. If the issue was previously undisclosed,
we'll also mention your name in the credits.
## Responsible Disclosure
In some cases, we may apply a responsible disclosure process to reported or
otherwise discovered vulnerabilities. We will usually do that for a critical
vulnerability, and only if we have a good reason to believe information about
it is not yet public.
This process involves providing an early notification about the vulnerability,
its impact and mitigations to a short list of vendors under a time-limited
embargo on public disclosure.
If you believe you should be on the list, please contact us and we will
consider your request based on the above criteria.

TLS Support
===========
Getting Started
---------------
### Building
To build with TLS support you'll need OpenSSL development libraries (e.g.
libssl-dev on Debian/Ubuntu).
To build TLS support as Redis built-in:
Run `make BUILD_TLS=yes`.
Or to build TLS as Redis module:
Run `make BUILD_TLS=module`.
Note that sentinel mode does not support TLS module.
### Tests
To run Redis test suite with TLS, you'll need TLS support for TCL (i.e.
`tcl-tls` package on Debian/Ubuntu).
1. Run `./utils/gen-test-certs.sh` to generate a root CA and a server
certificate.
2. Run `./runtest --tls` or `./runtest-cluster --tls` to run Redis and Redis
Cluster tests in TLS mode.
3. Run `./runtest --tls-module` or `./runtest-cluster --tls-module` to
run Redis and Redis cluster tests in TLS mode with Redis module.
### Running manually
To manually run a Redis server with TLS mode (assuming `gen-test-certs.sh` was
invoked so sample certificates/keys are available):
For TLS built-in mode:
./src/redis-server --tls-port 6379 --port 0 \
--tls-cert-file ./tests/tls/redis.crt \
--tls-key-file ./tests/tls/redis.key \
--tls-ca-cert-file ./tests/tls/ca.crt
For TLS module mode:
./src/redis-server --tls-port 6379 --port 0 \
--tls-cert-file ./tests/tls/redis.crt \
--tls-key-file ./tests/tls/redis.key \
--tls-ca-cert-file ./tests/tls/ca.crt \
--loadmodule src/redis-tls.so
To connect to this Redis server with `redis-cli`:
./src/redis-cli --tls \
--cert ./tests/tls/redis.crt \
--key ./tests/tls/redis.key \
--cacert ./tests/tls/ca.crt
This will disable TCP and enable TLS on port 6379. It's also possible to have
both TCP and TLS available, but you'll need to assign different ports.
To make a Replica connect to the master using TLS, use `--tls-replication yes`,
and to make Redis Cluster use TLS across nodes use `--tls-cluster yes`.
Connections
-----------
All socket operations now go through a connection abstraction layer that hides
I/O and read/write event handling from the caller.
**Multi-threading I/O is not currently supported for TLS**, as a TLS connection
needs to do its own manipulation of AE events which is not thread safe. The
solution is probably to manage independent AE loops for I/O threads and longer
term association of connections with threads. This may potentially improve
overall performance as well.
Sync IO for TLS is currently implemented in a hackish way, i.e. making the
socket blocking and configuring socket-level timeout. This means the timeout
value may not be so accurate, and there would be a lot of syscall overhead.
However I believe that getting rid of syncio completely in favor of pure async
work is probably a better move than trying to fix that. For replication it would
probably not be so hard. For cluster keys migration it might be more difficult,
but there are probably other good reasons to improve that part anyway.
To-Do List
----------
- [ ] redis-benchmark support. The current implementation is a mix of using
hiredis for parsing and basic networking (establishing connections), but
directly manipulating sockets for most actions. This will need to be cleaned
up for proper TLS support. The best approach is probably to migrate to hiredis
async mode.
- [ ] redis-cli `--slave` and `--rdb` support.
Multi-port
----------
Consider the implications of allowing TLS to be configured on a separate port,
making Redis listening on multiple ports:
1. Startup banner port notification
2. Proctitle
3. How slaves announce themselves
4. Cluster bus port calculation

This directory contains all Redis dependencies, except for the libc that
should be provided by the operating system.
* **Jemalloc** is our memory allocator, used as replacement for libc malloc on Linux by default. It has good performances and excellent fragmentation behavior. This component is upgraded from time to time.
* **hiredis** is the official C client library for Redis. It is used by redis-cli, redis-benchmark and Redis Sentinel. It is part of the Redis official ecosystem but is developed externally from the Redis repository, so we just upgrade it as needed.
* **linenoise** is a readline replacement. It is developed by the same authors of Redis but is managed as a separated project and updated as needed.
* **lua** is Lua 5.1 with minor changes for security and additional libraries.
* **hdr_histogram** Used for per-command latency tracking histograms.
How to upgrade the above dependencies
===
Jemalloc
---
Jemalloc is modified with changes that allow us to implement the Redis
active defragmentation logic. However this feature of Redis is not mandatory
and Redis is able to understand if the Jemalloc version it is compiled
against supports such Redis-specific modifications. So in theory, if you
are not interested in the active defragmentation, you can replace Jemalloc
just following these steps:
1. Remove the jemalloc directory.
2. Substitute it with the new jemalloc source tree.
3. Edit the Makefile located in the same directory as the README you are
reading, and change the --with-version in the Jemalloc configure script
options with the version you are using. This is required because otherwise
Jemalloc configuration script is broken and will not work nested in another
git repository.
However note that we change Jemalloc settings via the `configure` script of Jemalloc using the `--with-lg-quantum` option, setting it to the value of 3 instead of 4. This provides us with more size classes that better suit the Redis data structures, in order to gain memory efficiency.
If you want to upgrade Jemalloc while also providing support for
active defragmentation, in addition to the above steps you need to perform
the following additional steps:
5. In Jemalloc tree, file `include/jemalloc/jemalloc_macros.h.in`, make sure
to add `#define JEMALLOC_FRAG_HINT`.
6. Implement the function `je_get_defrag_hint()` inside `src/jemalloc.c`. You
can see how it is implemented in the current Jemalloc source tree shipped
with Redis, and rewrite it according to the new Jemalloc internals, if they
changed, otherwise you could just copy the old implementation if you are
upgrading just to a similar version of Jemalloc.
#### Updating/upgrading jemalloc
The jemalloc directory is pulled as a subtree from the upstream jemalloc github repo. To update it you should run from the project root:
1. `git subtree pull --prefix deps/jemalloc https://github.com/jemalloc/jemalloc.git <version-tag> --squash`<br>
This should hopefully merge the local changes into the new version.
2. In case any conflicts arise (due to our changes) you'll need to resolve them and commit.
3. Reconfigure jemalloc:<br>
```sh
rm deps/jemalloc/VERSION deps/jemalloc/configure
cd deps/jemalloc
./autogen.sh --with-version=<version-tag>-0-g0
```
4. Update jemalloc's version in `deps/Makefile`: search for "`--with-version=<old-version-tag>-0-g0`" and update it accordingly.
5. Commit the changes (VERSION,configure,Makefile).
Hiredis
---
Hiredis is used by Sentinel, `redis-cli` and `redis-benchmark`. Like Redis, uses the SDS string library, but not necessarily the same version. In order to avoid conflicts, this version has all SDS identifiers prefixed by `hi`.
1. `git subtree pull --prefix deps/hiredis https://github.com/redis/hiredis.git <version-tag> --squash`<br>
This should hopefully merge the local changes into the new version.
2. Conflicts will arise (due to our changes) you'll need to resolve them and commit.
Linenoise
---
Linenoise is rarely upgraded as needed. The upgrade process is trivial since
Redis uses a non modified version of linenoise, so to upgrade just do the
following:
1. Remove the linenoise directory.
2. Substitute it with the new linenoise source tree.
Lua
---
We use Lua 5.1 and no upgrade is planned currently, since we don't want to break
Lua scripts for new Lua features: in the context of Redis Lua scripts the
capabilities of 5.1 are usually more than enough, the release is rock solid,
and we definitely don't want to break old scripts.
So upgrading of Lua is up to the Redis project maintainers and should be a
manual procedure performed by taking a diff between the different versions.
Currently we have at least the following differences between official Lua 5.1
and our version:
1. Makefile is modified to allow a different compiler than GCC.
2. We have the implementation source code, and directly link to the following external libraries: `lua_cjson.o`, `lua_struct.o`, `lua_cmsgpack.o` and `lua_bit.o`.
3. There is a security fix in `ldo.c`, line 498: The check for `LUA_SIGNATURE[0]` is removed in order to avoid direct bytecode execution.
Hdr_Histogram
---
Updated source can be found here: https://github.com/HdrHistogram/HdrHistogram_c
We use a customized version based on master branch commit e4448cf6d1cd08fff519812d3b1e58bd5a94ac42.
1. Compare all changes under /hdr_histogram directory to upstream master commit e4448cf6d1cd08fff519812d3b1e58bd5a94ac42
2. Copy updated files from newer version onto files in /hdr_histogram.
3. Apply the changes from 1 above to the updated files.

README for fast_float v6.1.4
----------------------------------------------
We're using the fast_float library[1] in our (compiled-in)
floating-point fast_float_strtod implementation for faster and more
portable parsing of 64 decimal strings.
The single file fast_float.h is an amalgamation of the entire library,
which can be (re)generated with the amalgamate.py script (from the
fast_float repository) via the command
```
git clone https://github.com/fastfloat/fast_float
cd fast_float
git checkout v6.1.4
python3 ./script/amalgamate.py --license=MIT \
> $REDIS_SRC/deps/fast_float/fast_float.h
```

Creative Commons Legal Code
CC0 1.0 Universal
CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
HEREUNDER.
Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator
and subsequent owner(s) (each and all, an "owner") of an original work of
authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for
the purpose of contributing to a commons of creative, cultural and
scientific works ("Commons") that the public can reliably and without fear
of later claims of infringement build upon, modify, incorporate in other
works, reuse and redistribute as freely as possible in any form whatsoever
and for any purposes, including without limitation commercial purposes.
These owners may contribute to the Commons to promote the ideal of a free
culture and the further production of creative, cultural and scientific
works, or to gain reputation or greater distribution for their Work in
part through the use and efforts of others.
For these and/or other purposes and motivations, and without any
expectation of additional consideration or compensation, the person
associating CC0 with a Work (the "Affirmer"), to the extent that he or she
is an owner of Copyright and Related Rights in the Work, voluntarily
elects to apply CC0 to the Work and publicly distribute the Work under its
terms, with knowledge of his or her Copyright and Related Rights in the
Work and the meaning and intended legal effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be
protected by copyright and related or neighboring rights ("Copyright and
Related Rights"). Copyright and Related Rights include, but are not
limited to, the following:
i. the right to reproduce, adapt, distribute, perform, display,
communicate, and translate a Work;
ii. moral rights retained by the original author(s) and/or performer(s);
iii. publicity and privacy rights pertaining to a person's image or
likeness depicted in a Work;
iv. rights protecting against unfair competition in regards to a Work,
subject to the limitations in paragraph 4(a), below;
v. rights protecting the extraction, dissemination, use and reuse of data
in a Work;
vi. database rights (such as those arising under Directive 96/9/EC of the
European Parliament and of the Council of 11 March 1996 on the legal
protection of databases, and under any national implementation
thereof, including any amended or successor version of such
directive); and
vii. other similar, equivalent or corresponding rights throughout the
world based on applicable law or treaty, and any national
implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention
of, applicable law, Affirmer hereby overtly, fully, permanently,
irrevocably and unconditionally waives, abandons, and surrenders all of
Affirmer's Copyright and Related Rights and associated claims and causes
of action, whether now known or unknown (including existing as well as
future claims and causes of action), in the Work (i) in all territories
worldwide, (ii) for the maximum duration provided by applicable law or
treaty (including future time extensions), (iii) in any current or future
medium and for any number of copies, and (iv) for any purpose whatsoever,
including without limitation commercial, advertising or promotional
purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
member of the public at large and to the detriment of Affirmer's heirs and
successors, fully intending that such Waiver shall not be subject to
revocation, rescission, cancellation, termination, or any other legal or
equitable action to disrupt the quiet enjoyment of the Work by the public
as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason
be judged legally invalid or ineffective under applicable law, then the
Waiver shall be preserved to the maximum extent permitted taking into
account Affirmer's express Statement of Purpose. In addition, to the
extent the Waiver is so judged Affirmer hereby grants to each affected
person a royalty-free, non transferable, non sublicensable, non exclusive,
irrevocable and unconditional license to exercise Affirmer's Copyright and
Related Rights in the Work (i) in all territories worldwide, (ii) for the
maximum duration provided by applicable law or treaty (including future
time extensions), (iii) in any current or future medium and for any number
of copies, and (iv) for any purpose whatsoever, including without
limitation commercial, advertising or promotional purposes (the
"License"). The License shall be deemed effective as of the date CC0 was
applied by Affirmer to the Work. Should any part of the License for any
reason be judged legally invalid or ineffective under applicable law, such
partial invalidity or ineffectiveness shall not invalidate the remainder
of the License, and in such case Affirmer hereby affirms that he or she
will not (i) exercise any of his or her remaining Copyright and Related
Rights in the Work or (ii) assert any associated claims and causes of
action with respect to the Work, in either case contrary to Affirmer's
express Statement of Purpose.
4. Limitations and Disclaimers.
a. No trademark or patent rights held by Affirmer are waived, abandoned,
surrendered, licensed or otherwise affected by this document.
b. Affirmer offers the Work as-is and makes no representations or
warranties of any kind concerning the Work, express, implied,
statutory or otherwise, including without limitation warranties of
title, merchantability, fitness for a particular purpose, non
infringement, or the absence of latent or other defects, accuracy, or
the present or absence of errors, whether or not discoverable, all to
the greatest extent permissible under applicable law.
c. Affirmer disclaims responsibility for clearing rights of other persons
that may apply to the Work or any use thereof, including without
limitation any person's Copyright and Related Rights in the Work.
Further, Affirmer disclaims responsibility for obtaining any necessary
consents, permissions or other rights required for any use of the
Work.
d. Affirmer understands and acknowledges that Creative Commons is not a
party to this document and has no duty or obligation with respect to
this CC0 or use of the Work.

HdrHistogram_c: 'C' port of High Dynamic Range (HDR) Histogram
HdrHistogram
----------------------------------------------
[![Gitter chat](https://badges.gitter.im/HdrHistogram/HdrHistogram.png)](https://gitter.im/HdrHistogram/HdrHistogram)
This port contains a subset of the functionality supported by the Java
implementation. The current supported features are:
* Standard histogram with 64 bit counts (32/16 bit counts not supported)
* All iterator types (all values, recorded, percentiles, linear, logarithmic)
* Histogram serialisation (encoding version 1.2, decoding 1.0-1.2)
* Reader/writer phaser and interval recorder
Features not supported, but planned
* Auto-resizing of histograms
Features unlikely to be implemented
* Double histograms
* Atomic/Concurrent histograms
* 16/32 bit histograms
# Simple Tutorial
## Recording values
```C
#include <hdr_histogram.h>
struct hdr_histogram* histogram;
// Initialise the histogram
hdr_init(
1, // Minimum value
INT64_C(3600000000), // Maximum value
3, // Number of significant figures
&histogram) // Pointer to initialise
// Record value
hdr_record_value(
histogram, // Histogram to record to
value) // Value to record
// Record value n times
hdr_record_values(
histogram, // Histogram to record to
value, // Value to record
10) // Record value 10 times
// Record value with correction for co-ordinated omission.
hdr_record_corrected_value(
histogram, // Histogram to record to
value, // Value to record
1000) // Record with expected interval of 1000.
// Print out the values of the histogram
hdr_percentiles_print(
histogram,
stdout, // File to write to
5, // Granularity of printed values
1.0, // Multiplier for results
CLASSIC); // Format CLASSIC/CSV supported.
```
## More examples
For more detailed examples of recording and logging results look at the
[hdr_decoder](examples/hdr_decoder.c)
and [hiccup](examples/hiccup.c)
examples. You can run hiccup and decoder
and pipe the results of one into the other.
```
$ ./examples/hiccup | ./examples/hdr_decoder

[Full Changelog](https://github.com/redis/hiredis/compare/v0.14.1...v1.0.0)
**BREAKING CHANGES**:
* `redisOptions` now has two timeout fields. One for connecting, and one for commands. If you're presently using `options->timeout` you will need to change it to use `options->connect_timeout`. (See [example](https://github.com/redis/hiredis/commit/38b5ae543f5c99eb4ccabbe277770fc6bc81226f#diff-86ba39d37aa829c8c82624cce4f049fbL36))
* Bulk and multi-bulk lengths less than -1 or greater than `LLONG_MAX` are now protocol errors. This is consistent
with the RESP specification. On 32-bit platforms, the upper bound is lowered to `SIZE_MAX`.
* `redisReplyObjectFunctions.createArray` now takes `size_t` for its length parameter.

* Better handling of NULL reply in example code (Jan-Erik Rediger [1b8ed3])
* Prevent overflow when formatting an error (Jan-Erik Rediger [0335cb])
* Compatibility fix for strerror_r (Tom Lee [bb1747])
* Properly detect integer parse/overflow errors (Justin Brewer [93421f])
* Adds CI for Windows and cygwin fixes (owent, [6c53d6, 6c3e40])
* Catch a buffer overflow when formatting the error message
* Import latest upstream sds. This breaks applications that are linked against the old hiredis v0.13
* Fix warnings, when compiled with -Wshadow
* Make hiredis compile in Cygwin on Windows, now CI-tested
* Bulk and multi-bulk lengths less than -1 or greater than `LLONG_MAX` are now
protocol errors. This is consistent with the RESP specification. On 32-bit
platforms, the upper bound is lowered to `SIZE_MAX`.
* Remove backwards compatibility macro's
This removes the following old function aliases, use the new name now:
| Old | New |
| --------------------------- | ---------------------- |
| redisReplyReaderCreate | redisReaderCreate |
| redisReplyReaderCreate | redisReaderCreate |
| redisReplyReaderFree | redisReaderFree |
| redisReplyReaderFeed | redisReaderFeed |
| redisReplyReaderGetReply | redisReaderGetReply |
| redisReplyReaderSetPrivdata | redisReaderSetPrivdata |
| redisReplyReaderGetObject | redisReaderGetObject |
| redisReplyReaderGetError | redisReaderGetError |
* The `DEBUG` variable in the Makefile was renamed to `DEBUG_FLAGS`
Previously it broke some builds for people that had `DEBUG` set to some arbitrary value,
due to debugging other software.
By renaming we avoid unintentional name clashes.
Simply rename `DEBUG` to `DEBUG_FLAGS` in your environment to make it working again.
### 0.13.3 (2015-09-16)
* Revert "Clear `REDIS_CONNECTED` flag when connection is closed".
* Make tests pass on FreeBSD (Thanks, Giacomo Olgeni)
If the `REDIS_CONNECTED` flag is cleared,
the async onDisconnect callback function will never be called.
This causes problems as the disconnect is never reported back to the user.
### 0.13.2 (2015-08-25)
* Prevent crash on pending replies in async code (Thanks, @switch-st)
* Clear `REDIS_CONNECTED` flag when connection is closed (Thanks, Jerry Jacobs)
* Add MacOS X addapter (Thanks, @dizzus)
* Add Qt adapter (Thanks, Pietro Cerutti)
* Add Ivykis adapter (Thanks, Gergely Nagy)
All adapters are provided as is and are only tested where possible.
### 0.13.1 (2015-05-03)
This is a bug fix release.
The new `reconnect` method introduced new struct members, which clashed with pre-defined names in pre-C99 code.
Another commit forced C99 compilation just to make it work, but of course this is not desirable for outside projects.
Other non-C99 code can now use hiredis as usual again.
Sorry for the inconvenience.
* Fix memory leak in async reply handling (Salvatore Sanfilippo)
* Rename struct member to avoid name clash with pre-c99 code (Alex Balashov, ncopa)
### 0.13.0 (2015-04-16)
This release adds a minimal Windows compatibility layer.
The parser, standalone since v0.12.0, can now be compiled on Windows
(and thus used in other client libraries as well)
* Windows compatibility layer for parser code (tzickel)
* Properly escape data printed to PKGCONF file (Dan Skorupski)
* Fix tests when assert() undefined (Keith Bennett, Matt Stancliff)
* Implement a reconnect method for the client context, this changes the structure of `redisContext` (Aaron Bedra)
### 0.12.1 (2015-01-26)
* Fix `make install`: DESTDIR support, install all required files, install PKGCONF in proper location
* Fix `make test` as 32 bit build on 64 bit platform
### 0.12.0 (2015-01-22)
* Add optional KeepAlive support
* Try again on EINTR errors
* Add libuv adapter
* Add IPv6 support
* Remove possibility of multiple close on same fd
* Add ability to bind source address on connect
* Add redisConnectFd() and redisFreeKeepFd()
* Fix getaddrinfo() memory leak
* Free string if it is unused (fixes memory leak)
* Improve redisAppendCommandArgv performance 2.5x
* Add support for SO_REUSEADDR
* Fix redisvFormatCommand format parsing
* Add GLib 2.0 adapter
* Refactor reading code into read.c
* Fix errno error buffers to not clobber errors
* Generate pkgconf during build
* Silence _BSD_SOURCE warnings
* Improve digit counting for multibulk creation
### 0.11.0
* Increase the maximum multi-bulk reply depth to 7.

Hiredis is a minimalistic C client library for the Redis database.
It is minimalistic because it just adds minimal support for the protocol, \
but at the same time it uses a high level printf-alike API in order to make \
it much higher level than otherwise suggested by its minimal code base and the \
lack of explicit bindings for every Redis command.
Apart from supporting sending commands and receiving replies, it comes with a \
reply parser that is decoupled from the I/O layer. It is a stream parser designed \
for easy reusability, which can for instance be used in higher level language bindings \
for efficient reply parsing.
Hiredis only supports the binary-safe Redis protocol, so you can use it with any Redis \
version >= 1.2.0.
The library comes with multiple APIs. There is the synchronous API, the asynchronous API \
and the reply parsing API.")

The library comes with multiple APIs. There is the
*synchronous API*, the *asynchronous API* and the *reply parsing API*.
## Upgrading to `1.1.0`
Almost all users will simply need to recompile their applications against the newer version of hiredis.
**NOTE**: Hiredis can now return `nan` in addition to `-inf` and `inf` in a `REDIS_REPLY_DOUBLE`.
Applications that deal with `RESP3` doubles should make sure to account for this.
## Upgrading to `1.0.2`
<span style="color:red">NOTE: v1.0.1 erroneously bumped SONAME, which is why it is skipped here.</span>
Version 1.0.2 is simply 1.0.0 with a fix for [CVE-2021-32765](https://github.com/redis/hiredis/security/advisories/GHSA-hfm9-39pp-55p2). They are otherwise identical.
## Upgrading to `1.0.0`
Version 1.0.0 marks the first stable release of Hiredis.
It includes some minor breaking changes, mostly to make the exposed API more uniform and self-explanatory.
It also bundles the updated `sds` library, to sync up with upstream and Redis.
For code changes see the [Changelog](CHANGELOG.md).
_Note: As described below, a few member names have been changed but most applications should be able to upgrade with minor code changes and recompiling._
## IMPORTANT: Breaking changes from `0.14.1` -> `1.0.0`
* `redisContext` has two additional members (`free_privdata`, and `privctx`).
* `redisOptions.timeout` has been renamed to `redisOptions.connect_timeout`, and we've added `redisOptions.command_timeout`.
* `redisReplyObjectFunctions.createArray` now takes `size_t` instead of `int` for its length parameter.
## IMPORTANT: Breaking changes when upgrading from 0.13.x -> 0.14.x
Bulk and multi-bulk lengths less than -1 or greater than `LLONG_MAX` are now
protocol errors. This is consistent with the RESP specification. On 32-bit
platforms, the upper bound is lowered to `SIZE_MAX`.
Change `redisReply.len` to `size_t`, as it denotes the the size of a string
User code should compare this to `size_t` values as well. If it was used to
compare to other values, casting might be necessary or can be removed, if
casting was applied before.

```
redisContext *redisConnect(const char *ip, int port);
void *redisCommand(redisContext *c, const char *format, ...);
void freeReplyObject(void *reply);
### Connecting
The function `redisConnect` is used to create a so-called `redisContext`. The
context is where Hiredis holds state for a connection. The `redisContext`
struct has an integer `err` field that is non-zero when the connection is in
struct has an integer `err` field that is non-zero when an the connection is in
an error state. The field `errstr` will contain a string with a description of
the error. More information on errors can be found in the **Errors** section.
After trying to connect to Redis using `redisConnect` you should
check the `err` field to see if establishing the connection was successful:
```c
redisContext *c = redisConnect("127.0.0.1", 6379);
if (c == NULL || c->err) {
if (c) {
redisContext *c = redisConnect("127.0.0.1", 6379);
if (c != NULL && c->err) {
printf("Error: %s\n", c->errstr);
// handle error
} else {
printf("Can't allocate redis context\n");
}
}
```
One can also use `redisConnectWithOptions` which takes a `redisOptions` argument
that can be configured with endpoint information as well as many different flags
to change how the `redisContext` will be configured.
```c
redisOptions opt = {0};
/* One can set the endpoint with one of our helper macros */
if (tcp) {
REDIS_OPTIONS_SET_TCP(&opt, "localhost", 6379);
} else {
REDIS_OPTIONS_SET_UNIX(&opt, "/tmp/redis.sock");
}
/* And privdata can be specified with another helper */
REDIS_OPTIONS_SET_PRIVDATA(&opt, myPrivData, myPrivDataDtor);
/* Finally various options may be set via the `options` member, as described below */
opt->options |= REDIS_OPT_PREFER_IPV4;
```
If a connection is lost, `int redisReconnect(redisContext *c)` can be used to restore the connection using the same endpoint and options as the given context.
### Configurable redisOptions flags
There are several flags you may set in the `redisOptions` struct to change default behavior. You can specify the flags via the `redisOptions->options` member.
| Flag | Description |
| --- | --- |
| REDIS\_OPT\_NONBLOCK | Tells hiredis to make a non-blocking connection. |
| REDIS\_OPT\_REUSEADDR | Tells hiredis to set the [SO_REUSEADDR](https://man7.org/linux/man-pages/man7/socket.7.html) socket option |
| REDIS\_OPT\_PREFER\_IPV4<br>REDIS\_OPT\_PREFER_IPV6<br>REDIS\_OPT\_PREFER\_IP\_UNSPEC | Informs hiredis to either prefer IPv4 or IPv6 when invoking [getaddrinfo](https://man7.org/linux/man-pages/man3/gai_strerror.3.html). `REDIS_OPT_PREFER_IP_UNSPEC` will cause hiredis to specify `AF_UNSPEC` in the getaddrinfo call, which means both IPv4 and IPv6 addresses will be searched simultaneously.<br>Hiredis prefers IPv4 by default. |
| REDIS\_OPT\_NO\_PUSH\_AUTOFREE | Tells hiredis to not install the default RESP3 PUSH handler (which just intercepts and frees the replies). This is useful in situations where you want to process these messages in-band. |
| REDIS\_OPT\_NOAUTOFREEREPLIES | **ASYNC**: tells hiredis not to automatically invoke `freeReplyObject` after executing the reply callback. |
| REDIS\_OPT\_NOAUTOFREE | **ASYNC**: Tells hiredis not to automatically free the `redisAsyncContext` on connection/communication failure, but only if the user makes an explicit call to `redisAsyncDisconnect` or `redisAsyncFree` |
*Note: A `redisContext` is not thread-safe.*
### Other configuration using socket options
The following socket options are applied directly to the underlying socket.
The values are not stored in the `redisContext`, so they are not automatically applied when reconnecting using `redisReconnect()`.
These functions return `REDIS_OK` on success.
On failure, `REDIS_ERR` is returned and the underlying connection is closed.
To configure these for an asyncronous context (see *Asynchronous API* below), use `ac->c` to get the redisContext out of an asyncRedisContext.
```C
int redisEnableKeepAlive(redisContext *c);
int redisEnableKeepAliveWithInterval(redisContext *c, int interval);
```
Enables TCP keepalive by setting the following socket options (with some variations depending on OS):
* `SO_KEEPALIVE`;
* `TCP_KEEPALIVE` or `TCP_KEEPIDLE`, value configurable using the `interval` parameter, default 15 seconds;
* `TCP_KEEPINTVL` set to 1/3 of `interval`;
* `TCP_KEEPCNT` set to 3.
```C
int redisSetTcpUserTimeout(redisContext *c, unsigned int timeout);
```
Set the `TCP_USER_TIMEOUT` Linux-specific socket option which is as described in the `tcp` man page:
> When the value is greater than 0, it specifies the maximum amount of time in milliseconds that trans mitted data may remain unacknowledged before TCP will forcibly close the corresponding connection and return ETIMEDOUT to the application.
> If the option value is specified as 0, TCP will use the system default.
### Sending commands
There are several ways to issue commands to Redis. The first that will be introduced is
`redisCommand`. This function takes a format similar to printf. In the simplest form,
it is used like this:
```c
reply = redisCommand(context, "SET foo bar");
```
reply = redisCommand(context, "SET foo bar");
The specifier `%s` interpolates a string in the command, and uses `strlen` to
determine the length of the string:
```c
reply = redisCommand(context, "SET foo %s", value);
```
reply = redisCommand(context, "SET foo %s", value);
When you need to pass binary safe strings in a command, the `%b` specifier can be
used. Together with a pointer to the string, it requires a `size_t` length argument
of the string:
```c
reply = redisCommand(context, "SET foo %b", value, (size_t) valuelen);
```
reply = redisCommand(context, "SET foo %b", value, (size_t) valuelen);
Internally, Hiredis splits the command in different arguments and will
convert it to the protocol used to communicate with Redis.
One or more spaces separates arguments, so you can use the specifiers
anywhere in an argument:
```c
reply = redisCommand(context, "SET key:%s %s", myid, value);
```
reply = redisCommand(context, "SET key:%s %s", myid, value);

* **`REDIS_REPLY_DOUBLE`**:
* The command replied with a double-precision floating point number.

Like the MAP type, the data is identical to an array response except there are no duplicate values.
* **`REDIS_REPLY_PUSH`**:
* An array that can be generated spontaneously by Redis.
This array response will always contain at least two subelements. The first contains the type of `PUSH` message (e.g. `message`, or `invalidate`), and the second being a sub-array with the `PUSH` payload itself.
* **`REDIS_REPLY_ATTR`**:
* An array structurally identical to a `MAP` but intended as meta-data about a reply.
_As of Redis 6.0.6 this reply type is not used in Redis_
* **`REDIS_REPLY_BIGNUM`**:
* A string representing an arbitrarily large signed or unsigned integer value.
The number will be encoded as a string in the `str` member of `redisReply`.
* **`REDIS_REPLY_VERB`**:
* A verbatim string, intended to be presented to the user without modification.
The string payload is stored in the `str` member, and type data is stored in the `vtype` member (e.g. `txt` for raw text or `md` for markdown).

The asynchronous context can hold a disconnect callback function that is called when the
connection is disconnected (either because of an error or per user request). This function should
have the following prototype:
```c
void(const redisAsyncContext *c, int status);

On a *connect*, the `status` argument is set to `REDIS_OK` if the connection attempt succeeded. In this
case, the context is ready to accept commands. If it is called with `REDIS_ERR` then the
connection attempt failed. The `err` field in the context can be accessed to find out the cause of the error.
After a failed connection attempt, the context object is automatically freed by the library after calling
the connect callback. This may be a good point to create a new context and retry the connection.
void(const redisAsyncContext *c, int status);
On a disconnect, the `status` argument is set to `REDIS_OK` when disconnection was initiated by the
user, or `REDIS_ERR` when the disconnection was caused by an error. When it is `REDIS_ERR`, the `err`

The context object is always free'd after the disconnect callback fired. When a reconnect is needed,

might look something like this:

### Sending commands and their callbacks
@@ -489,60 +267,43 @@ In an asynchronous context, commands are automatically pipelined due to the natu
Therefore, unlike the synchronous API, there is only a single way to send commands.
Because commands are sent to Redis asynchronously, issuing a command requires a callback function
that is called when the reply is received. Reply callbacks should have the following prototype:
```c
void(redisAsyncContext *c, void *reply, void *privdata);
```
void(redisAsyncContext *c, void *reply, void *privdata);
The `privdata` argument can be used to curry arbitrary data to the callback from the point where
the command is initially queued for execution.
The functions that can be used to issue commands in an asynchronous context are:
```c
int redisAsyncCommand(
redisAsyncContext *ac, redisCallbackFn *fn, void *privdata,
const char *format, ...);
int redisAsyncCommandArgv(
redisAsyncContext *ac, redisCallbackFn *fn, void *privdata,
int argc, const char **argv, const size_t *argvlen);
```
int redisAsyncCommand(
redisAsyncContext *ac, redisCallbackFn *fn, void *privdata,
const char *format, ...);
int redisAsyncCommandArgv(
redisAsyncContext *ac, redisCallbackFn *fn, void *privdata,
int argc, const char **argv, const size_t *argvlen);
Both functions work like their blocking counterparts. The return value is `REDIS_OK` when the command
was successfully added to the output buffer and `REDIS_ERR` otherwise. Example: when the connection
is being disconnected per user-request, no new commands may be added to the output buffer and `REDIS_ERR` is
returned on calls to the `redisAsyncCommand` family.
If the reply for a command with a `NULL` callback is read, it is immediately freed. When the callback
for a command is non-`NULL`, the memory is freed immediately following the callback: the reply is only
If the reply for a command with a `NULL` callback is read, it is immediately free'd. When the callback
for a command is non-`NULL`, the memory is free'd immediately following the callback: the reply is only
valid for the duration of the callback.
All pending callbacks are called with a `NULL` reply when the context encountered an error.
For every command issued, with the exception of **SUBSCRIBE** and **PSUBSCRIBE**, the callback is
called exactly once. Even if the context object id disconnected or deleted, every pending callback
will be called with a `NULL` reply.
For **SUBSCRIBE** and **PSUBSCRIBE**, the callbacks may be called repeatedly until an `unsubscribe`
message arrives. This will be the last invocation of the callback. In case of error, the callbacks
may receive a final `NULL` reply instead.
### Disconnecting
An asynchronous connection can be terminated using:
```c
void redisAsyncDisconnect(redisAsyncContext *ac);
```
void redisAsyncDisconnect(redisAsyncContext *ac);
When this function is called, the connection is **not** immediately terminated. Instead, new
commands are no longer accepted and the connection is only terminated when all pending commands
have been written to the socket, their respective replies have been read and their respective
callbacks have been executed. After this, the disconnection callback is executed with the
`REDIS_OK` status and the context object is freed.
The connection can be forcefully disconnected using
```c
void redisAsyncFree(redisAsyncContext *ac);
```
In this case, nothing more is written to the socket, all pending callbacks are called with a `NULL`
reply and the disconnection callback is called with `REDIS_OK`, after which the context object
is freed.
`REDIS_OK` status and the context object is free'd.

For instance if you have a normal Redis context you can set the maximum idle
buffer to zero (unlimited) just with:
```c
context->reader->maxbuf = 0;
```
context->reader->maxbuf = 0;
This should be done only in order to maximize performances when working with
large payloads. The context should be set back to `REDIS_READER_MAX_BUF` again
as soon as possible in order to prevent allocation of useless memory.
### Reader max array elements
By default the hiredis reply parser sets the maximum number of multi-bulk elements
to 2^32 - 1 or 4,294,967,295 entries. If you need to process multi-bulk replies
with more than this many elements you can set the value higher or to zero, meaning
unlimited with:
```c
context->reader->maxelements = 0;
```
## SSL/TLS Support
### Building
SSL/TLS support is not built by default and requires an explicit flag:
make USE_SSL=1
This requires OpenSSL development package (e.g. including header files to be
available.
When enabled, SSL/TLS support is built into extra `libhiredis_ssl.a` and
`libhiredis_ssl.so` static/dynamic libraries. This leaves the original libraries
unaffected so no additional dependencies are introduced.
### Using it
First, you'll need to make sure you include the SSL header file:
```c
#include <hiredis/hiredis.h>
#include <hiredis/hiredis_ssl.h>
```
You will also need to link against `libhiredis_ssl`, **in addition** to
`libhiredis` and add `-lssl -lcrypto` to satisfy its dependencies.
Hiredis implements SSL/TLS on top of its normal `redisContext` or
`redisAsyncContext`, so you will need to establish a connection first and then
initiate an SSL/TLS handshake.
#### Hiredis OpenSSL Wrappers
Before Hiredis can negotiate an SSL/TLS connection, it is necessary to
initialize OpenSSL and create a context. You can do that in two ways:
1. Work directly with the OpenSSL API to initialize the library's global context
and create `SSL_CTX *` and `SSL *` contexts. With an `SSL *` object you can
call `redisInitiateSSL()`.
2. Work with a set of Hiredis-provided wrappers around OpenSSL, create a
`redisSSLContext` object to hold configuration and use
`redisInitiateSSLWithContext()` to initiate the SSL/TLS handshake.
```c
/* An Hiredis SSL context. It holds SSL configuration and can be reused across
* many contexts.
*/
redisSSLContext *ssl_context;
/* An error variable to indicate what went wrong, if the context fails to
* initialize.
*/
redisSSLContextError ssl_error = REDIS_SSL_CTX_NONE;
/* Initialize global OpenSSL state.
*
* You should call this only once when your app initializes, and only if
* you don't explicitly or implicitly initialize OpenSSL it elsewhere.
*/
redisInitOpenSSL();
/* Create SSL context */
ssl_context = redisCreateSSLContext(
"cacertbundle.crt", /* File name of trusted CA/ca bundle file, optional */
"/path/to/certs", /* Path of trusted certificates, optional */
"client_cert.pem", /* File name of client certificate file, optional */
"client_key.pem", /* File name of client private key, optional */
"redis.mydomain.com", /* Server name to request (SNI), optional */
&ssl_error);
if(ssl_context == NULL || ssl_error != REDIS_SSL_CTX_NONE) {
/* Handle error and abort... */
/* e.g.
printf("SSL error: %s\n",
(ssl_error != REDIS_SSL_CTX_NONE) ?
redisSSLContextGetError(ssl_error) : "Unknown error");
// Abort
*/
}
/* Create Redis context and establish connection */
c = redisConnect("localhost", 6443);
if (c == NULL || c->err) {
/* Handle error and abort... */
}
/* Negotiate SSL/TLS */
if (redisInitiateSSLWithContext(c, ssl_context) != REDIS_OK) {
/* Handle error, in c->err / c->errstr */
}
```
## RESP3 PUSH replies
Redis 6.0 introduced PUSH replies with the reply-type `>`. These messages are generated spontaneously and can arrive at any time, so must be handled using callbacks.
### Default behavior
Hiredis installs handlers on `redisContext` and `redisAsyncContext` by default, which will intercept and free any PUSH replies detected. This means existing code will work as-is after upgrading to Redis 6 and switching to `RESP3`.
### Custom PUSH handler prototypes
The callback prototypes differ between `redisContext` and `redisAsyncContext`.
#### redisContext
```c
void my_push_handler(void *privdata, void *reply) {
/* Handle the reply */
/* Note: We need to free the reply in our custom handler for
blocking contexts. This lets us keep the reply if
we want. */
freeReplyObject(reply);
}
```
#### redisAsyncContext
```c
void my_async_push_handler(redisAsyncContext *ac, void *reply) {
/* Handle the reply */
/* Note: Because async hiredis always frees replies, you should
not call freeReplyObject in an async push callback. */
}
```
### Installing a custom handler
There are two ways to set your own PUSH handlers.
1. Set `push_cb` or `async_push_cb` in the `redisOptions` struct and connect with `redisConnectWithOptions` or `redisAsyncConnectWithOptions`.
```c
redisOptions = {0};
REDIS_OPTIONS_SET_TCP(&options, "127.0.0.1", 6379);
options->push_cb = my_push_handler;
redisContext *context = redisConnectWithOptions(&options);
```
2. Call `redisSetPushCallback` or `redisAsyncSetPushCallback` on a connected context.
```c
redisContext *context = redisConnect("127.0.0.1", 6379);
redisSetPushCallback(context, my_push_handler);
```
_Note `redisSetPushCallback` and `redisAsyncSetPushCallback` both return any currently configured handler, making it easy to override and then return to the old value._
### Specifying no handler
If you have a unique use-case where you don't want hiredis to automatically intercept and free PUSH replies, you will want to configure no handler at all. This can be done in two ways.
1. Set the `REDIS_OPT_NO_PUSH_AUTOFREE` flag in `redisOptions` and leave the callback function pointer `NULL`.
```c
redisOptions = {0};
REDIS_OPTIONS_SET_TCP(&options, "127.0.0.1", 6379);
options->options |= REDIS_OPT_NO_PUSH_AUTOFREE;
redisContext *context = redisConnectWithOptions(&options);
```
3. Call `redisSetPushCallback` with `NULL` once connected.
```c
redisContext *context = redisConnect("127.0.0.1", 6379);
redisSetPushCallback(context, NULL);
```
_Note: With no handler configured, calls to `redisCommand` may generate more than one reply, so this strategy is only applicable when there's some kind of blocking `redisGetReply()` loop (e.g. `MONITOR` or `SUBSCRIBE` workloads)._
## Allocator injection
Hiredis uses a pass-thru structure of function pointers defined in [alloc.h](https://github.com/redis/hiredis/blob/f5d25850/alloc.h#L41) that contain the currently configured allocation and deallocation functions. By default they just point to libc (`malloc`, `calloc`, `realloc`, etc).
### Overriding
One can override the allocators like so:
```c
hiredisAllocFuncs myfuncs = {
.mallocFn = my_malloc,
.callocFn = my_calloc,
.reallocFn = my_realloc,
.strdupFn = my_strdup,
.freeFn = my_free,
};
// Override allocators (function returns current allocators if needed)
hiredisAllocFuncs orig = hiredisSetAllocators(&myfuncs);
```
To reset the allocators to their default libc function simply call:
```c
hiredisResetAllocators();
```
