Enrico Giordani a822725873 [Cleanup] Code refactoring to minimize changes in antirez code. 2015-07-16 11:48:46 +02:00
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.

The new return value is the number of keys existing, among the ones

Date:   Fri Jun 19 21:22:48 2015 +0200

    RejoinCOWPages and background threads should be synchronized

    RejoinCOWPages is copying dirty pages to a new view
    of the memory map.
    If another thread modifies the heap between when
    RejoincCOWPages copies the data and when the view is
    remapped, the modification will be lost, leading to a
    memory corruption.
    In short, when RejoincCOWPages is running, all other
    threads must be stopped.

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.

Related to issues #2609 and #2612.

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 60a28fad8a Net: improve prepareClientToWrite() error handling and comments. 
When we fail to setup the write handler it does not make sense to take
the client around, it is missing writes: whatever is a client or a slave
anyway the connection should terminated ASAP.

Moreover what the function does exactly with its return value, and in
which case the write handler is installed on the socket, was not clear,
so the functions comment are improved to make the goals of the function
more obvious.

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.

This commit moves the process of generating a new config epoch without

FAILOVER option forcing the failover when no master majority is
reachable).

Moreover the commit moves other functions which are similarly related to
config epochs in a new logical section of the cluster.c file, just for
clarity.

antirez 2d7d75adb3 Net: clientsArePaused() should not touch blocked clients. 
When the list of unblocked clients were processed, btype was set to
blocking type none, but the client remained flagged with REDIS_BLOCKED.
When timeout is reached (or when the client disconnects), unblocking it
will trigger an assertion.

There is no need to process pending requests from blocked clients, so

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 e772c8e7eb redis-cli --latency-dist: one gray more, and --mono support. 2015-03-18 11:29:32 +01:00
antirez 99764d2722 redis-cli --latency-dist, hopefully better palette. 
Less grays: more readable palette since usually we have a non linear
distribution of percentages and very near gray tones are hard to take
apart. Final part of the palette is gradient from yellow to red. The red
part is hardly reached because of usual distribution of latencies, but
shows up mainly when latencies are very high because of the logarithmic
scale, this is coherent to what people expect: red = bad.

Leandro López (inkel) b10c2b7bb2 Support CLIENT commands in Redis Sentinel 
When trying to debug sentinel connections or max connections errors it
would be very useful to have the ability to see the list of connected
clients to a running sentinel. At the same time it would be very helpful
to be able to name each sentinel connection or kill offending clients.

This commits adds the already defined CLIENT commands back to Redis
Sentinel.

antirez 4793ea982a redis-cli: interactive reconnection for latency modes. 
--stat mode already used to reconnect automatically if the server is no

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.

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 23cc0a3f1c AOF rewrite: set iterator var to NULL when freed. 
The cleanup code expects that if 'di' is not NULL, it is a valid
iterator that should be freed.

The result of this bug was a crash of the AOF rewriting process if an
error occurred after the DBs data are written and the iterator is no
longer valid.

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.

Same as the original bind fixes (we just missed these the

to a specific IP address (e.g. with multiple IP aliases on one

To perform a socket write() for each RDB rio API write call was

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

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.

happens to always be populated.

Howver technically connect(2) with a non blocking socket may return an

Recently we introduced the ability to load truncated AOFs, but
unfortuantely the support was broken since the server, after loading 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.

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 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

master.

antirez 2570eeb711 tryObjectEncoding(): use shared objects with maxmemory and non-LRU policy. 
In order to make sure every object has its own private LRU counter, when
maxmemory is enabled tryObjectEncoding() does not use the pool of shared
integers. However when the policy is not LRU-based, it does not make
sense to do so, and it is much better to save memory using shared
integers.

antirez 2264b9816c Variadic PING with support for Pub/Sub. 
PING can now be called with an additional arugment, behaving exactly
like the ECHO command. PING can now also be called in Pub/Sub mode (with
one more more subscriptions to channels / patterns) in order to trigger
the delivery of an asynchronous pong message with the optional payload.

This fixes issue #420.

antirez 23c1408963 PubSub clients refactoring and new PUBSUB flag. 
The code tested many times if a client had active Pub/Sub subscriptions
by checking the length of a list and dictionary where the patterns and
channels are stored. This was substituted with a client flag called
REDIS_PUBSUB that is simpler to test for. Moreover in order to manage
this flag some code was refactored.

This commit is believed to have no effects in the behavior of the
server.

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
if you sent this:

OBJECT foo

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 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.

Eventual configuration convergence is guaranteed by our periodic hello

message to other Sentinal and Redis instances within the next 100
milliseconds of a config update, which is practically better than
waiting a few seconds.

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 8d75a20ab1 Sentinel: send SLAVEOF with MULTI, CLIENT KILL, CONFIG REWRITE. 
This implements the new Sentinel-Client protocol for the Sentinel part:
now instances are reconfigured using a transaction that ensures that the
config is rewritten in the target instance, and that clients lose the
connection with the instance, in order to be forced to: ask Sentinel,
reconnect to the instance, and verify the instance role with the new
ROLE command.

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.
 2014-06-21 15:18:32 +02:00
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
users who use large strings of just integers.

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.

Fixes #1118 again.

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 8b059f06d7 Cluster: check that configEpoch never goes back. 
Since there are ways to alter the configEpoch outside of the failover
procedure (for exampel CLUSTER SET-CONFIG-EPOCH and via the configEpoch
collision resolution algorithm), make always sure, before replacing our
configEpoch with a new one, that it is greater than the current one.

server to set its configEpoch to a value smaller than the current one
(since configEpochs are obtained using currentEpoch).

The bug totally break the Redis Cluster algorithms and protocols
allowing for permanent split brain conditions about the slots
configuration as shown in issue #1799.

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.

for config save/fsync flags which are slow to execute and not a good
idea to repeat without a good reason.

antirez 5685d15af1 Fixed typo in CLUSTER RESET implementation. 2014-05-20 17:45:50 +02:00
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

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.

antirez e84dcabf83 Cluster: forced failover implemented. 
Using CLUSTER FAILOVER FORCE it is now possible to failover a master in
a forced way, which means:

1) No check to understand if the master is up is performed.
2) No data age of the slave is checked. Evan a slave with very old data
   can manually failover a master in this way.
3) No chat with the master is attempted to reach its replication offset:
   the master can just be down.
 2014-05-20 17:45:49 +02:00
antirez b5cdd42bf3 Cluster: bypass data_age check for manual failovers. 
Automatic failovers only happen in Redis Cluster if the slave trying to
be elected was disconnected from its master for no more than 10 times
the node-timeout value. However there should be no such a check for
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.

The same change was operated for normal client connections. This is

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 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 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.

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

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.

Better results can be achieved by compensating for the bias of the raw

The curve used was found using this web page:

The following form is given:

No element is provided in the above case so if 'myhll' var does not
exist the result is to just create an empty HLL structure, and no update
will be performed on the registers.

In this case, the DB should still be set dirty and the command
propagated.

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.
 2014-04-16 15:09:45 +02:00
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
object unshared (if refcount > 1) and encoded in raw format (if encoding
is not already REDIS_ENCODING_RAW).

This was cut & pasted many times in multiple places of the code. This
commit puts the small logic needed into a function called
dbUnshareStringValue().
 2014-04-16 15:09:45 +02:00
antirez f3aa086b6d Use endian neutral hash function for HyperLogLog. 
We need to be sure that you can save a dataset in a Redis instance,
reload it in a different architecture, and continue to count in the same
HyperLogLog structure.

So 32 and 64 bit, little or bit endian, must all guarantee to output the
same hash for the same element.
 2014-04-16 15:09:45 +02:00
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.

antirez 6837863902 Cluster: redis-trib cluster allocation more even across nodes. 
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
masters always end with unique config epochs, however failures during
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

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.

antirez 317ec18214 Fixed undefined variable value with certain code paths. 
In sentinelFlushConfig() fd could be undefined when the following if

Matt Stancliff 65e0452886 Fix data loss when save AOF/RDB with no free space 
Previously, the (!fp) would only catch lack of free space
under OS X.  Linux waits to discover it can't write until
it actually writes contents to disk.

(fwrite() returns success even if the underlying file
has no free space to write into.  All the errors
only show up at flush/sync/close time.)

Matt Stancliff 4af72d326e Cluster: Restore proper trib master iteration 
This got removed in 2e5c394 during a new feature addition.

The prior commit had "break if masters.length == masters_count"
but we are guaranteed to aready have that condition met since
otherwise we would haven't gotten this far.

Without this break statement, it's possible some masters may
be forgotten and have zero replicas while other masters have
more than their requested number of replicas.

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:

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 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 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

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

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.

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.

 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 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
set a lower limit for the failover timeout of two seconds.

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

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.

This patch fixes much confusions.

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.

This is still code to rework in order to use agreement to obtain a new

has a configEpoch of 0. In this special condition to have the maximum

others are).

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

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 reply does not make sense today, every Sentinel should reply with

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,

antirez 0296aab6da AOF write error: retry with a frequency of 1 hz. 2014-02-12 16:57:08 +01:00
antirez dd73a7bf43 AOF: don't abort on write errors unless fsync is 'always'. 
A system similar to the RDB write error handling is used, in which when
we can't write to the AOF file, writes are no longer accepted until we
are able to write again.

For fsync == always we still abort on errors since there is currently no
easy way to avoid replying with success to the user otherwise, and this
would violate the contract with the user of only acknowledging data
already secured on disk.

antirez 6d550f2de4 Cluster: configEpoch assignment in SETNODE improved. 
Avoid to trash a configEpoch for every slot migrated if this node has
already the max configEpoch across the cluster.

Still work to do in this area but this avoids both ending with a very
high configEpoch without any reason and to flood the system with fsyncs.
 2014-02-11 10:21:58 +01:00
antirez 585e9fb886 Cluster: clusterSetStartupEpoch() made more generally useful. 
The actual goal of the function was to get the max configEpoch found in
the cluster, so make it general by removing the assignment of the max
epoch to currentEpoch that is useful only at startup.
 2014-02-11 10:21:55 +01:00
antirez 8b5196addf Cluster: always increment the configEpoch in SETNODE after import. 
Removed a stale conditional preventing the configEpoch from incrementing
after the import in certain conditions. Since the master got a new slot
it should always claim a new configuration.
 2014-02-11 10:21:52 +01:00
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).
 2014-02-11 00:39:24 +01:00
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.
 2014-02-11 00:39:20 +01:00
antirez 77c6fa65f1 Cluster: conditions to clear "migrating" on slot for SETSLOT ... NODE changed. 
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.

What is Redis?
--------------
[![NuGet version](http://img.shields.io/nuget/v/redis-64.svg?style=flat-square)](http://www.nuget.org/packages/redis-64/)
[![NuGet downloads](http://img.shields.io/nuget/dt/redis-64.svg?style=flat-square)](http://www.nuget.org/packages/redis-64/)
Redis is often referred as a *data structures* server. What this means is that Redis provides access to mutable data structures via a set of commands, which are sent using a *server-client* model with TCP sockets and a simple protocol. So different processes can query and modify the same data structures in a shared way.
[![Chocolatey version](http://img.shields.io/chocolatey/v/redis-64.svg?style=flat-square)](http://www.chocolatey.org/packages/redis-64/)
[![Chocolatey downloads](http://img.shields.io/chocolatey/dt/redis-64.svg?style=flat-square)](http://www.chocolatey.org/packages/redis-64/)
Data structures implemented into Redis have a few special properties:
Redis on Windows
===
* Redis cares to store them on disk, even if they are always served and modified into the server memory. This means that Redis is fast, but that is also non-volatile.
* Implementation of data structures stress on memory efficiency, so data structures inside Redis will likely use less memory compared to the same data structure modeled using an high level programming language.
* Redis offers a number of features that are natural to find in a database, like replication, tunable levels of durability, cluster, high availability.
## Redis 2.8 Branch
Another good example is to think of Redis as a more complex version of memcached, where the operations are not just SETs and GETs, but operations to work with complex data types like Lists, Sets, ordered data structures, and so forth.
- This is a port for Windows based on Redis 2.8.
- There is support for the 64-bit version. We have dropped official support for the 32-bit version, though you can build it from source if desired.
- You can download the latest binaries (unsigned) from [http://github.com/MSOpenTech/redis/releases](http://github.com/MSOpenTech/redis/releases "Release page"). For releases prior to 2.8.17.1, the binaries can found in a zip file inside the source archive, under the bin/release folder.
- Signed binaries can be downloaded using Nuget and Chocolatey.
- There is a replacement for the UNIX fork() API that simulates the copy-on-write behavior using a memory mapped file.
- Because Redis makes some assumptions about the values of File Descriptors, we have built a virtual file descriptor mapping layer.
- Redis can be installed as a Windows Service.

Building Redis
--------------
## How to configure and deploy Redis on Windows
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.
- [Memory Configuration](https://github.com/MSOpenTech/redis/wiki/Memory-Configuration "Memory Configuration")
- [Redis on Windows](https://raw.githubusercontent.com/MSOpenTech/redis/2.8/Redis%20on%20Windows.md "Redis on Windows")
- [Windows Service Documentation](https://raw.githubusercontent.com/MSOpenTech/redis/2.8/Windows%20Service%20Documentation.md "Windows Service Documentation")
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.
## How to build Redis using Visual Studio
It is as simple as:
You can use the free Visual Studio Community edition available at http://www.visualstudio.com/products/visual-studio-community-vs.
% make
- Open the solution file msvs\redisserver.sln in Visual Studio, select a build configuration (Debug or Release) and target (x64) then build.
You can run a 32 bit Redis binary using:
This should create the following executables in the msvs\$(Target)\$(Configuration) folder:
% make 32bit
- redis-server.exe
- redis-benchmark.exe
- redis-cli.exe
- redis-check-dump.exe
- redis-check-aof.exe
After building Redis is a good idea to test it, using:
## Unit Testing
% make test
To run the Redis test suite requires some manual work:
Fixing build problems with dependencies or cached build options
---------
- The tests assume that the binaries are in the src folder. Use mklink to create a symbolic link to the files in the msvs\x64\Debug|Release folders. You will
need symbolic links for src\redis-server, src\redis-benchmark, src\redis-check-aof, src\redis-check-dump, src\redis-cli, and src\redis-sentinel.
- The tests make use of TCL. This must be installed separately.
- To run the tests you need to have a Unix shell on your machine, or MinGW tools in your path. To execute the tests, run the following command:
"tclsh8.5.exe tests/test_helper.tcl --clients N", where N is the number of parallel clients . If a Unix shell is not installed you may see the
following error message: "couldn't execute "cat": no such file or directory".
- By default the test suite launches 16 parallel tests, but some of the tests may fail when the number of clients is greater than 2.
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 changed.
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 at 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`.

MSOpenTech’s Redis on Windows
=============================
Redis is an open source, high performance, key-value store. Values may contain strings, hashes, lists, sets and sorted sets. Redis has been developed primarily for UNIX-like operating systems.
Our goal is to provide a version of Redis that runs on Windows with a performance essentially equal to the performance of Redis on an equivalent UNIX machine.
We strive to have a stable, functionally equivalent and comparably performing version of Redis on Windows. We have achieved performance nearly identical to the POSIX version running head-to-head on identical hardware across the network. Aside from feature differences that help Redis take advantage of the Windows infrastructure, our version of Redis should work in most situations with the identical setup and configuration that one would use on a POSIX operating system.
How is Redis on Windows implemented?
====================================
Redis is a C code base that compiles under Visual Studio. Most of the code compiles with only minor changes to the code due to syntactical differences between compilers and low level API differences on Windows. There are a few areas where there are significant differences in how efficient Windows programs operate relative to POSIX programs. We have encapsulated most these differences in a platform specific library. The areas where there are significant differences are:
- Networking APIs
- POSIX File Descriptors
- POSIX fork()
- Logging
- Windows Services API
Networking Differences
----------------------
The Windows networking stack is split between user mode code and kernel mode code. Transitions between user and kernel mode are expensive operations. The POSIX networking APIs on Windows utilize a programming model that incurs significant performance loss due to the kernel/user mode transitions. Efficient Windows networking code instead uses the IO Completion Port model to reduce the impact of this behavior. The APIs used and the programming model for IO Completion is different enough that we were forced to implement a new networking layer in in Redis.
File Descriptors
----------------
In a POSIX operating system all data sources (files, pipes, sockets, mail slots, etc.) are referenced in code with a handle called a file descriptor. These are low value integers that increment by one with each successive file descriptor created in a given program. All POSIX APIs that work with file descriptors will function without the programmer having to know what kind of data source a file descriptor represents. On Windows generally each kind of data source has a separate kind of HANDLE. APIs that work with one HANDLE type will not work with another kind of HANDLE. In order to make Redis operate with its assumptions about file descriptor values and data source agnosticism, we implemented a Redis File Descriptor API layer.
fork()
------
The POSIX version of Redis uses the fork() API. There is no equivalent in Windows, and it is an exceedingly difficult API to completely simulate. For most of the uses of fork() we have used Windows specific programming idioms to bypass the need to use a fork()-like API. The one case where we could not do so was with the point-in-time heap snapshot behavior that the Redis persistence model is based on. We tried several different approaches to work around the need for a fork()-like API, but always ran into significant performance penalties and stability issues.
Our current approach is to simulate the point-in-time snapshot behavior aspect of fork() without doing a complete simulation of fork(). We do this with a memory mapped file that contains the Redis heap. When a fork() operation is required we do the following:
- Mark every page in the memory mapped file with the Copy on Write page protection
- Start a child process and pass it the handle to the memory mapped file
- Signal the child to start the AOF or RDB persistence process on the memory shared via the memory mapped file
- Wait (asynchronously) for the child process to finish
- Map the changes in the Redis heap that occurred during the fork() operation back into the memory mapped file.
The upside with this implementation is that our performance and stability is now on par with the POSIX version of Redis. The down side is that we have a runtime disk space requirement for Redis equal to the size of the Redis memory mapped heap. The disk space requirement defaults to:
- The size specified by the –maxheap flag if present, otherwise
- 50% more than the --maxmemory setting if present, otherwise
- The size of physical RAM
We also have a runtime page file commit requirement that varies depending on the amount data in the Redis heap during the quasi-fork operation. The maximum for this is about 3 times the size of the memory mapped file. This is usually not a problem because the default configuration of Windows allows the page file to grow to 3.5 times the size of physical memory. There are scenarios where 3<sup>rd</sup> party programs also compete for system swap space at runtime.
Logging
-------
In addition to file based logging, the POSIX version of Redis supports logging via the syslog facility. The equivalent in Windows is the Event Log. With the recent addition of the Windows Service code we have added support for logging to the Event Log. We have mapped the –syslogxxxx flags for this purpose.
Windows Service
---------------
In version 2.8.9 we are adding support to make Redis operate as a service. See the RedisService.docx file included with the GitHub binary distribution for a description of the service commands available.
Redis on Windows Best Practices
===============================
Binary Distributions
--------------------
The GitHub repository should be considered a work in progress until we release the NuGet and Chocolatey packages and tag the repository at that released version.
For instance, the Windows Service feature has taken many iterations with community input to get right. The initial Windows service code was checked in on April 3. Since that time we have added the following to the service based on community input:
- Preshutdown notification in order to clean up the memory mapped file consistently.
- Code to identify and clean up orphaned memory mapped files left behind when a machine running Redis as a service crashes or loses power.
- Self elevation of the Redis executable so that service commands would work from a non-elevated command prompt.
- Service naming so that multiple instances of the Redis service could be installed on one machine.
- Automatically adjusting folder permissions so that when Redis is run under the NETWORK SERVICE account it could modify the files in the installation directory.
- Moved all of the pre-main() error reporting code (service and quasi-fork code) that could write errors to stdout to use the Redis logging code. This allows service initialization errors to reach the Event Log. This required intercepting all of the command line and conf file arguments before main() in order to properly initialize the logging engine. There were several fixes related to the intricacies of how to interpret the arguments passed to Redis.
The final service code has been released as of June 25 in the 2.8.9 Redis-64 packages.
Heap Sizing
-----------
Native heaps are prone to fragmentation. If we are not able to allocate more heap space due to fragmentation Redis will flag the problem and exit. Unlike the POSIX version of Redis, our heap size is constrained by both by disk space and by swap file space. It is important to consider the how much data you are expecting to put into Redis, and how much fragmentation you are likely to see in the Redis heap. With very high levels of fragmentation the 50% overhead that –maxmemory imposes may not be enough to prevent running out of heap space. In this case, the use of –maxheap will supersede the –maxmemory default heap setting.
Installation and Maintenance
----------------------------
Since Redis uses system swap space, the most stable configurations will only have Redis running on essentially a virgin operating system install.
Redis is xcopy deployable. There should be no problem upgrading versions by simply copying new binaries over old ones (assuming they are not currently in use).
Service Account
---------------
When using Redis as a Windows service, the default installation configures Redis to run under the system’s NETWORK SERVICE account. There are some environments where another account must be used (perhaps a domain service account). Configuration of this account needs to be done manually at this point with the service control manager. If this is done, it is also important to give read/write/create permission to the folder that the Redis executable is in to this user identity.
How to develop for Redis
========================
You will need a client library for accessing Redis. There are a wide variety of client libraries available as listed at <http://redis.io/clients>.

Running Redis as a Service
==========================
If you installed Redis using the MSI package, then Redis was already installed as a Windows service. Nothing further to do. If you would like to change its settings, you can update the *redis.windows.conf* file and then restart the Redis service (Run -\> services.msc -\> Redis -\> Restart).
During installation of the MSI you can either use the installer’s user interface to update the port that Redis listens at and the firewall exception or run it silently without a UI. The following examples show how to install from the command line:
**default install (port 6379 and firewall exception ON):**
*msiexec /i Redis-x64.msi *
**set port and turn OFF firewall exception:**
*msiexec /i Redis-x64.msi PORT=1234 FIREWALL\_ON=""*
**set port and turn ON firewall exception:**
*msiexec /i Redis-x64.msi PORT=1234 FIREWALL\_ON=1*
**install with no user interface:**
*msiexec /quiet /i Redis-x64.msi*
If you did *not* install Redis using the MSI package, then you still run Redis as a Windows service by following these instructions:
In order to better integrate with the Windows Services model, new command line arguments have been introduced to Redis. These service arguments require an elevated user context in order to connect to the service control manager. If these commands are invoked from a non-elevated context, Redis will attempt to create an elevated context in which to execute these commands. This will cause a User Account Control dialog to be displayed by Windows and may require Administrative user credentials in order to proceed.
Installing the Service
----------------------
*--service-install*
This must be the first argument on the redis-server command line. Arguments after this are passed in the order they occur to Redis when the service is launched. The service will be configured as Autostart and will be launched as "NT AUTHORITY\\NetworkService". Upon successful installation a success message will be displayed and Redis will exit.
This command does not start the service.
For instance:
redis-server --service-install redis.windows.conf --loglevel verbose
Uninstalling the Service
------------------------
*--service-uninstall*
This will remove the Redis service configuration information from the registry. Upon successful uninstallation a success message will be displayed and Redis will exit.
This does command not stop the service.
For instance:
redis-server --service-uninstall
Starting the Service
--------------------
*--service-start*
This will start the Redis service. Upon successful start, a success message will be displayed and Redis will begin running.
For instance:
redis-server --service-start
Stopping the Service
--------------------
*--service-stop*
This will stop the Redis service. Upon successful termination a success message will be displayed and Redis will exit.
For instance:
redis-server --service-stop
Naming the Service
------------------
*--service-name **name***
This optional argument may be used with any of the preceding commands to set the name of the installed service. This argument should follow the service-install, service-start, service-stop or service-uninstall commands, and precede any arguments to be passed to Redis via the service-install command.
The following would install and start three separate instances of Redis as a service:
redis-server --service-install –service-name redisService1 –port 10001
redis-server --service-start –service-name redisService1
redis-server --service-install –service-name redisService2 –port 10002
redis-server --service-start –service-name redisService2
redis-server --service-install –service-name redisService3 –port 10003
redis-server --service-start –service-name redisService3

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.
* **geohash-int** is inside the dependencies directory but is actually part of the Redis project, since it is our private fork (heavily modified) of a library initially developed for Ardb, which is in turn a fork of Redis.
* **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.
How to upgrade the above dependencies
===
Jemalloc
---
Jemalloc is unmodified. We only change 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.
So in order to upgrade jemalloc:
1. Remove the jemalloc directory.
2. Substitute it with the new jemalloc source tree.
Geohash
---
This is never upgraded since it's part of the Redis project. If there are changes to merge from Ardb there is the need to manually check differences, but at this point the source code is pretty different.
Hiredis
---
Hiredis uses the SDS string library, that must be the same version used inside Redis itself. Hiredis is also very critical for Sentinel. Historically Redis often used forked versions of hiredis in a way or the other. In order to upgrade it is adviced to take a lot of care:
1. Check with diff if hiredis API changed and what impact it could have in Redis.
2. Make sure thet the SDS library inside Hiredis and inside Redis are compatible.
3. After the upgrade, run the Redis Sentinel test.
4. Check manually that redis-cli and redis-benchmark behave as expecteed, since we have no tests for CLI utilities currently.
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 toa void direct bytecode exectuion.

* 4.0.3 (September 24, 2015)
This bugfix release continues the trend of xallocx() and heap profiling fixes.
Bug fixes:
- Fix xallocx(..., MALLOCX_ZERO) to zero all trailing bytes of large
allocations when --enable-cache-oblivious configure option is enabled.
- Fix xallocx(..., MALLOCX_ZERO) to zero trailing bytes of huge allocations
when resizing from/to a size class that is not a multiple of the chunk size.
- Fix prof_tctx_dump_iter() to filter out nodes that were created after heap
profile dumping started.
- Work around a potentially bad thread-specific data initialization
interaction with NPTL (glibc's pthreads implementation).
* 4.0.2 (September 21, 2015)
This bugfix release addresses a few bugs specific to heap profiling.
Bug fixes:
- Fix ixallocx_prof_sample() to never modify nor create sampled small
allocations. xallocx() is in general incapable of moving small allocations,
so this fix removes buggy code without loss of generality.
- Fix irallocx_prof_sample() to always allocate large regions, even when
alignment is non-zero.
- Fix prof_alloc_rollback() to read tdata from thread-specific data rather
than dereferencing a potentially invalid tctx.
* 4.0.1 (September 15, 2015)
This is a bugfix release that is somewhat high risk due to the amount of
refactoring required to address deep xallocx() problems. As a side effect of
these fixes, xallocx() now tries harder to partially fulfill requests for
optional extra space. Note that a couple of minor heap profiling
optimizations are included, but these are better thought of as performance
fixes that were integral to disovering most of the other bugs.
Optimizations:
- Avoid a chunk metadata read in arena_prof_tctx_set(), since it is in the
fast path when heap profiling is enabled. Additionally, split a special
case out into arena_prof_tctx_reset(), which also avoids chunk metadata
reads.
- Optimize irallocx_prof() to optimistically update the sampler state. The
prior implementation appears to have been a holdover from when
rallocx()/xallocx() functionality was combined as rallocm().
Bug fixes:
- Fix TLS configuration such that it is enabled by default for platforms on
which it works correctly.
- Fix arenas_cache_cleanup() and arena_get_hard() to handle
allocation/deallocation within the application's thread-specific data
cleanup functions even after arenas_cache is torn down.
- Fix xallocx() bugs related to size+extra exceeding HUGE_MAXCLASS.
- Fix chunk purge hook calls for in-place huge shrinking reallocation to
specify the old chunk size rather than the new chunk size. This bug caused
no correctness issues for the default chunk purge function, but was
visible to custom functions set via the "arena.<i>.chunk_hooks" mallctl.
- Fix heap profiling bugs:
+ Fix heap profiling to distinguish among otherwise identical sample sites
with interposed resets (triggered via the "prof.reset" mallctl). This bug
could cause data structure corruption that would most likely result in a
segfault.
+ Fix irealloc_prof() to prof_alloc_rollback() on OOM.
+ Make one call to prof_active_get_unlocked() per allocation event, and use
the result throughout the relevant functions that handle an allocation
event. Also add a missing check in prof_realloc(). These fixes protect
allocation events against concurrent prof_active changes.
+ Fix ixallocx_prof() to pass usize_max and zero to ixallocx_prof_sample()
in the correct order.
+ Fix prof_realloc() to call prof_free_sampled_object() after calling
prof_malloc_sample_object(). Prior to this fix, if tctx and old_tctx were
the same, the tctx could have been prematurely destroyed.
- Fix portability bugs:
+ Don't bitshift by negative amounts when encoding/decoding run sizes in
chunk header maps. This affected systems with page sizes greater than 8
KiB.
+ Rename index_t to szind_t to avoid an existing type on Solaris.
+ Add JEMALLOC_CXX_THROW to the memalign() function prototype, in order to
match glibc and avoid compilation errors when including both
jemalloc/jemalloc.h and malloc.h in C++ code.
+ Don't assume that /bin/sh is appropriate when running size_classes.sh
during configuration.
+ Consider __sparcv9 a synonym for __sparc64__ when defining LG_QUANTUM.
+ Link tests to librt if it contains clock_gettime(2).
* 4.0.0 (August 17, 2015)
This version contains many speed and space optimizations, both minor and
major. The major themes are generalization, unification, and simplification.
Although many of these optimizations cause no visible behavior change, their
cumulative effect is substantial.
New features:
- Normalize size class spacing to be consistent across the complete size
range. By default there are four size classes per size doubling, but this
is now configurable via the --with-lg-size-class-group option. Also add the
--with-lg-page, --with-lg-page-sizes, --with-lg-quantum, and
--with-lg-tiny-min options, which can be used to tweak page and size class
settings. Impacts:
+ Worst case performance for incrementally growing/shrinking reallocation
is improved because there are far fewer size classes, and therefore
copying happens less often.
+ Internal fragmentation is limited to 20% for all but the smallest size
classes (those less than four times the quantum). (1B + 4 KiB)
and (1B + 4 MiB) previously suffered nearly 50% internal fragmentation.
+ Chunk fragmentation tends to be lower because there are fewer distinct run
sizes to pack.
- Add support for explicit tcaches. The "tcache.create", "tcache.flush", and
"tcache.destroy" mallctls control tcache lifetime and flushing, and the
MALLOCX_TCACHE(tc) and MALLOCX_TCACHE_NONE flags to the *allocx() API
control which tcache is used for each operation.
- Implement per thread heap profiling, as well as the ability to
enable/disable heap profiling on a per thread basis. Add the "prof.reset",
"prof.lg_sample", "thread.prof.name", "thread.prof.active",
"opt.prof_thread_active_init", "prof.thread_active_init", and
"thread.prof.active" mallctls.
- Add support for per arena application-specified chunk allocators, configured
via the "arena.<i>.chunk_hooks" mallctl.
- Refactor huge allocation to be managed by arenas, so that arenas now
function as general purpose independent allocators. This is important in
the context of user-specified chunk allocators, aside from the scalability
benefits. Related new statistics:
+ The "stats.arenas.<i>.huge.allocated", "stats.arenas.<i>.huge.nmalloc",
"stats.arenas.<i>.huge.ndalloc", and "stats.arenas.<i>.huge.nrequests"
mallctls provide high level per arena huge allocation statistics.
+ The "arenas.nhchunks", "arenas.hchunk.<i>.size",
"stats.arenas.<i>.hchunks.<j>.nmalloc",
"stats.arenas.<i>.hchunks.<j>.ndalloc",
"stats.arenas.<i>.hchunks.<j>.nrequests", and
"stats.arenas.<i>.hchunks.<j>.curhchunks" mallctls provide per size class
statistics.
- Add the 'util' column to malloc_stats_print() output, which reports the
proportion of available regions that are currently in use for each small
size class.
- Add "alloc" and "free" modes for for junk filling (see the "opt.junk"
mallctl), so that it is possible to separately enable junk filling for
allocation versus deallocation.
- Add the jemalloc-config script, which provides information about how
jemalloc was configured, and how to integrate it into application builds.
- Add metadata statistics, which are accessible via the "stats.metadata",
"stats.arenas.<i>.metadata.mapped", and
"stats.arenas.<i>.metadata.allocated" mallctls.
- Add the "stats.resident" mallctl, which reports the upper limit of
physically resident memory mapped by the allocator.
- Add per arena control over unused dirty page purging, via the
"arenas.lg_dirty_mult", "arena.<i>.lg_dirty_mult", and
"stats.arenas.<i>.lg_dirty_mult" mallctls.
- Add the "prof.gdump" mallctl, which makes it possible to toggle the gdump
feature on/off during program execution.
- Add sdallocx(), which implements sized deallocation. The primary
optimization over dallocx() is the removal of a metadata read, which often
suffers an L1 cache miss.
- Add missing header includes in jemalloc/jemalloc.h, so that applications
only have to #include <jemalloc/jemalloc.h>.
- Add support for additional platforms:
+ Bitrig
+ Cygwin
+ DragonFlyBSD
+ iOS
+ OpenBSD
+ OpenRISC/or1k
Optimizations:
- Maintain dirty runs in per arena LRUs rather than in per arena trees of
dirty-run-containing chunks. In practice this change significantly reduces
dirty page purging volume.
- Integrate whole chunks into the unused dirty page purging machinery. This
reduces the cost of repeated huge allocation/deallocation, because it
effectively introduces a cache of chunks.
- Split the arena chunk map into two separate arrays, in order to increase
cache locality for the frequently accessed bits.
- Move small run metadata out of runs, into arena chunk headers. This reduces
run fragmentation, smaller runs reduce external fragmentation for small size
classes, and packed (less uniformly aligned) metadata layout improves CPU
cache set distribution.
- Randomly distribute large allocation base pointer alignment relative to page
boundaries in order to more uniformly utilize CPU cache sets. This can be
disabled via the --disable-cache-oblivious configure option, and queried via
the "config.cache_oblivious" mallctl.
- Micro-optimize the fast paths for the public API functions.
- Refactor thread-specific data to reside in a single structure. This assures
that only a single TLS read is necessary per call into the public API.
- Implement in-place huge allocation growing and shrinking.
- Refactor rtree (radix tree for chunk lookups) to be lock-free, and make
additional optimizations that reduce maximum lookup depth to one or two
levels. This resolves what was a concurrency bottleneck for per arena huge
allocation, because a global data structure is critical for determining
which arenas own which huge allocations.
Incompatible changes:
- Replace --enable-cc-silence with --disable-cc-silence to suppress spurious
warnings by default.
- Assure that the constness of malloc_usable_size()'s return type matches that
of the system implementation.
- Change the heap profile dump format to support per thread heap profiling,
rename pprof to jeprof, and enhance it with the --thread=<n> option. As a
result, the bundled jeprof must now be used rather than the upstream
(gperftools) pprof.
- Disable "opt.prof_final" by default, in order to avoid atexit(3), which can
internally deadlock on some platforms.
- Change the "arenas.nlruns" mallctl type from size_t to unsigned.
- Replace the "stats.arenas.<i>.bins.<j>.allocated" mallctl with
"stats.arenas.<i>.bins.<j>.curregs".
- Ignore MALLOC_CONF in set{uid,gid,cap} binaries.
- Ignore MALLOCX_ARENA(a) in dallocx(), in favor of using the
MALLOCX_TCACHE(tc) and MALLOCX_TCACHE_NONE flags to control tcache usage.
Removed features:
- Remove the *allocm() API, which is superseded by the *allocx() API.
- Remove the --enable-dss options, and make dss non-optional on all platforms
which support sbrk(2).
- Remove the "arenas.purge" mallctl, which was obsoleted by the
"arena.<i>.purge" mallctl in 3.1.0.
- Remove the unnecessary "opt.valgrind" mallctl; jemalloc automatically
detects whether it is running inside Valgrind.
- Remove the "stats.huge.allocated", "stats.huge.nmalloc", and
"stats.huge.ndalloc" mallctls.
- Remove the --enable-mremap option.
- Remove the "stats.chunks.current", "stats.chunks.total", and
"stats.chunks.high" mallctls.
Bug fixes:
- Fix the cactive statistic to decrease (rather than increase) when active
memory decreases. This regression was first released in 3.5.0.
- Fix OOM handling in memalign() and valloc(). A variant of this bug existed
in all releases since 2.0.0, which introduced these functions.
- Fix an OOM-related regression in arena_tcache_fill_small(), which could
cause cache corruption on OOM. This regression was present in all releases
from 2.2.0 through 3.6.0.
- Fix size class overflow handling for malloc(), posix_memalign(), memalign(),
calloc(), and realloc() when profiling is enabled.
- Fix the "arena.<i>.dss" mallctl to return an error if "primary" or
"secondary" precedence is specified, but sbrk(2) is not supported.
- Fix fallback lg_floor() implementations to handle extremely large inputs.
- Ensure the default purgeable zone is after the default zone on OS X.
- Fix latent bugs in atomic_*().
- Fix the "arena.<i>.dss" mallctl to handle read-only calls.
- Fix tls_model configuration to enable the initial-exec model when possible.
- Mark malloc_conf as a weak symbol so that the application can override it.
- Correctly detect glibc's adaptive pthread mutexes.
- Fix the --without-export configure option.

--disable-cache-oblivious
Disable cache-oblivious large allocation alignment for large allocation
requests with no alignment constraints. If this feature is disabled, all
large allocations are page-aligned as an implementation artifact, which can
severely harm CPU cache utilization. However, the cache-oblivious layout
comes at the cost of one extra page per large allocation, which in the
most extreme case increases physical memory usage for the 16 KiB size class
to 20 KiB.
--with-xslroot=<path>
Specify where to find DocBook XSL stylesheets when building the
documentation.
--with-lg-page=<lg-page>
Specify the base 2 log of the system page size. This option is only useful
when cross compiling, since the configure script automatically determines
the host's page size by default.
--with-lg-page-sizes=<lg-page-sizes>
Specify the comma-separated base 2 logs of the page sizes to support. This
option may be useful when cross-compiling in combination with
--with-lg-page, but its primary use case is for integration with FreeBSD's
libc, wherein jemalloc is embedded.
--with-lg-size-class-group=<lg-size-class-group>
Specify the base 2 log of how many size classes to use for each doubling in
size. By default jemalloc uses <lg-size-class-group>=2, which results in
e.g. the following size classes:
[...], 64,
80, 96, 112, 128,
160, [...]
<lg-size-class-group>=3 results in e.g. the following size classes:
[...], 64,
72, 80, 88, 96, 104, 112, 120, 128,
144, [...]
The minimal <lg-size-class-group>=0 causes jemalloc to only provide size
classes that are powers of 2:
[...],
64,
128,
256,
[...]
An implementation detail currently limits the total number of small size
classes to 255, and a compilation error will result if the
<lg-size-class-group> you specify cannot be supported. The limit is
roughly <lg-size-class-group>=4, depending on page size.
--with-lg-quantum=<lg-quantum>
Specify the base 2 log of the minimum allocation alignment. jemalloc needs
to know the minimum alignment that meets the following C standard
requirement (quoted from the April 12, 2011 draft of the C11 standard):
The pointer returned if the allocation succeeds is suitably aligned so
that it may be assigned to a pointer to any type of object with a
fundamental alignment requirement and then used to access such an object
or an array of such objects in the space allocated [...]
This setting is architecture-specific, and although jemalloc includes known
safe values for the most commonly used modern architectures, there is a
wrinkle related to GNU libc (glibc) that may impact your choice of
<lg-quantum>. On most modern architectures, this mandates 16-byte alignment
(<lg-quantum>=4), but the glibc developers chose not to meet this
requirement for performance reasons. An old discussion can be found at
https://sourceware.org/bugzilla/show_bug.cgi?id=206 . Unlike glibc,
jemalloc does follow the C standard by default (caveat: jemalloc
technically cheats if --with-lg-tiny-min is smaller than
--with-lg-quantum), but the fact that Linux systems already work around
this allocator noncompliance means that it is generally safe in practice to
let jemalloc's minimum alignment follow glibc's lead. If you specify
--with-lg-quantum=3 during configuration, jemalloc will provide additional
size classes that are not 16-byte-aligned (24, 40, and 56, assuming
--with-lg-size-class-group=2).
--with-lg-tiny-min=<lg-tiny-min>
Specify the base 2 log of the minimum tiny size class to support. Tiny
size classes are powers of 2 less than the quantum, and are only
incorporated if <lg-tiny-min> is less than <lg-quantum> (see
--with-lg-quantum). Tiny size classes technically violate the C standard
requirement for minimum alignment, and crashes could conceivably result if
the compiler were to generate instructions that made alignment assumptions,
both because illegal instruction traps could result, and because accesses
could straddle page boundaries and cause segmentation faults due to
accessing unmapped addresses.
The default of <lg-tiny-min>=3 works well in practice even on architectures
that technically require 16-byte alignment, probably for the same reason
--with-lg-quantum=3 works. Smaller tiny size classes can, and will, cause
crashes (see https://bugzilla.mozilla.org/show_bug.cgi?id=691003 for an
example).
This option is rarely useful, and is mainly provided as documentation of a
subtle implementation detail. If you do use this option, specify a
value in [3, ..., <lg-quantum>].
