antirez 7178cac031 Revert "Jemalloc updated to 4.4.0."
This reverts commit 153f2f00ea.

Jemalloc 4.4.0 is apparently causing deadlocks in certain
systems. See for example https://github.com/antirez/redis/issues/3799.
As a cautionary step we are reverting the commit back and
releasing a new stable Redis version.

antirez 33fad43c0f Fix MIGRATE closing of cached socket on error.
After investigating issue #3796, it was discovered that MIGRATE
could call migrateCloseSocket() after the original MIGRATE c->argv
was already rewritten as a DEL operation. As a result the host/port
passed to migrateCloseSocket() could be anything, often a NULL pointer
that gets deferenced crashing the server.

Now the socket is closed at an earlier time when there is a socket
error in a later stage where no retry will be performed, before we
rewrite the argument vector. Moreover a check was added so that later,
in the socket_err label, there is no further attempt at closing the
socket if the argument was rewritten.

This fix should resolve the bug reported in #3796.

antirez 3876d985a8 Ziplist: insertion bug under particular conditions fixed.
Ziplists had a bug that was discovered while investigating a different
issue, resulting in a corrupted ziplist representation, and a likely
segmentation foult and/or data corruption of the last element of the
ziplist, once the ziplist is accessed again.

The bug happens when a specific set of insertions / deletions is
performed so that an entry is encoded to have a "prevlen" field (the
length of the previous entry) of 5 bytes but with a count that could be
encoded in a "prevlen" field of a since byte. This could happen when the
"cascading update" process called by ziplistInsert()/ziplistDelete() in
certain contitious forces the prevlen to be bigger than necessary in
order to avoid too much data moving around.

Once such an entry is generated, inserting a very small entry
immediately before it will result in a resizing of the ziplist for a
count smaller than the current ziplist length (which is a violation,
inserting code expects the ziplist to get bigger actually). So an FF
byte is inserted in a misplaced position. Moreover a realloc() is
performed with a count smaller than the ziplist current length so the
final bytes could be trashed as well.

SECURITY IMPLICATIONS:

Currently it looks like an attacker can only crash a Redis server by
providing specifically choosen commands. However a FF byte is written
and there are other memory operations that depend on a wrong count, so
even if it is not immediately apparent how to mount an attack in order
to execute code remotely, it is not impossible at all that this could be
done. Attacks always get better... and we did not spent enough time in
order to think how to exploit this issue, but security researchers
or malicious attackers could.

REPRODUCING:

The bug can be reproduced with the following commands.

    redis-cli del list
    redis-cli rpush list one
    redis-cli rpush list two
    redis-cli rpush list
    AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
    redis-cli rpush list
    AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
    redis-cli rpush list three
    redis-cli rpush list a
    redis-cli lrem list 1
    AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
    redis-cli linsert list after
    AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
    10
    redis-cli lrange list 0 -1

Instead of "rpush list a", use "rpush list 10" in order to trigger a
data corruption instead of a crash.

antirez 874804da0c Security: Cross Protocol Scripting protection.
This is an attempt at mitigating problems due to cross protocol
scripting, an attack targeting services using line oriented protocols
like Redis that can accept HTTP requests as valid protocol, by
discarding the invalid parts and accepting the payloads sent, for
example, via a POST request.

For this to be effective, when we detect POST and Host: and terminate
the connection asynchronously, the networking code was modified in order
to never process further input. It was later verified that in a
pipelined request containing a POST command, the successive commands are
not executed.

A bug was reported in the context in issue #3631. The root cause of the

function was wrong.

A few debugging infos where enhanced and moved in other parts of the
code. A check to avoid steps=0 was added, but is unrelated to this
issue and I did not verified it was an actual bug in practice.

antirez 0539634777 Security: CONFIG SET client-output-buffer-limit overflow fixed.
This commit fixes a vunlerability reported by Cory Duplantis
of Cisco Talos, see TALOS-2016-0206 for reference.

CONFIG SET client-output-buffer-limit accepts as client class "master"
which is actually only used to implement CLIENT KILL. The "master" class
has ID 3. What happens is that the global structure:

    server.client_obuf_limits[class]

Is accessed with class = 3. However it is a 3 elements array, so writing
the 4th element means to write up to 24 bytes of memory *after* the end
of the array, since the structure is defined as:

    typedef struct clientBufferLimitsConfig {
        unsigned long long hard_limit_bytes;
        unsigned long long soft_limit_bytes;
        time_t soft_limit_seconds;
    } clientBufferLimitsConfig;

EVALUATION OF IMPACT:

Checking what's past the boundaries of the array in the global
'server' structure, we find AOF state fields:

    clientBufferLimitsConfig client_obuf_limits[CLIENT_TYPE_OBUF_COUNT];
    /* AOF persistence */
    int aof_state;                  /* AOF_(ON|OFF|WAIT_REWRITE) */
    int aof_fsync;                  /* Kind of fsync() policy */
    char *aof_filename;             /* Name of the AOF file */
    int aof_no_fsync_on_rewrite;    /* Don't fsync if a rewrite is in prog. */
    int aof_rewrite_perc;           /* Rewrite AOF if % growth is > M and... */
    off_t aof_rewrite_min_size;     /* the AOF file is at least N bytes. */
    off_t aof_rewrite_base_size;    /* AOF size on latest startup or rewrite. */
    off_t aof_current_size;         /* AOF current size. */

Writing to most of these fields should be harmless and only cause problems in
Redis persistence that should not escalate to security problems.
However unfortunately writing to "aof_filename" could be potentially a
security issue depending on the access pattern.

Searching for "aof.filename" accesses in the source code returns many different
usages of the field, including using it as input for open(), logging to the
Redis log file or syslog, and calling the rename() syscall.

It looks possible that attacks could lead at least to informations
disclosure of the state and data inside Redis. However note that the
attacker must already have access to the server. But, worse than that,
it looks possible that being able to change the AOF filename can be used
to mount more powerful attacks: like overwriting random files with AOF
data (easily a potential security issue as demostrated here:
http://antirez.com/news/96), or even more subtle attacks where the
AOF filename is changed to a path were a malicious AOF file is loaded
in order to exploit other potential issues when the AOF parser is fed
with untrusted input (no known issue known currently).

The fix checks the places where the 'master' class is specifiedf in
order to access configuration data structures, and return an error in
this cases.

WHO IS AT RISK?

The "master" client class was introduced in Redis in Jul 28 2015.
Every Redis instance released past this date is not vulnerable
while all the releases after this date are. Notably:

    Redis 3.0.x is NOT vunlerable.
    Redis 3.2.x IS vulnerable.
    Redis unstable is vulnerable.

In order for the instance to be at risk, at least one of the following
conditions must be true:

    1. The attacker can access Redis remotely and is able to send
       the CONFIG SET command (often banned in managed Redis instances).

    2. The attacker is able to control the "redis.conf" file and
       can wait or trigger a server restart.

The problem was fixed 26th September 2016 in all the releases affected.

This feature is useful, especially in deployments using Sentinel in

"ROLE" command, don't match the real addresses at which the slave is

antirez fdafe23315 Multiple GEORADIUS bugs fixed.
By grepping the continuous integration errors log a number of GEORADIUS
tests failures were detected.

Fortunately when a GEORADIUS failure happens, the test suite logs enough
information in order to reproduce the problem: the PRNG seed,
coordinates and radius of the query.

By reproducing the issues, three different bugs were discovered and
fixed in this commit. This commit also improves the already good
reporting of the fuzzer and adds the failure vectors as regression
tests.

The issues found:

1. We need larger squares around the poles in order to cover the area
requested by the user. There were already checks in order to use a
smaller step (larger squares) but the limit set (+/- 67 degrees) is not
enough in certain edge cases, so 66 is used now.

2. Even near the equator, when the search area center is very near the
edge of the square, the north, south, west or ovest square may not be
able to fully cover the specified radius. Now a test is performed at the
edge of the initial guessed search area, and larger squares are used in
case the test fails.

3. Because of rounding errors between Redis and Tcl, sometimes the test
signaled false positives. This is now addressed.

Whenever possible the original code was improved a bit in other ways. A
debugging example stanza was added in order to make the next debugging
session simpler when the next bug is found.

antirez a1bfe22a80 Replication: when possible start RDB saving ASAP.
In a previous commit the replication code was changed in order to
centralize the BGSAVE for replication trigger in replicationCron(),
however after further testings, the 1 second delay imposed by this
change is not acceptable.

So now the BGSAVE is only delayed if the AOF rewriting process is
active. However past comments made sure that replicationCron() is always
able to trigger the BGSAVE when needed, making the code generally more
robust.

The new code is more similar to the initial @oranagra patch where the
BGSAVE was delayed only if an AOF rewrite was in progress.

Trivia: delaying the BGSAVE uncovered a minor Sentinel issue that is now
fixed.

antirez 7ca69aff26 Sentinel: new test unit 07 that tests master down conditions. 2016-07-27 12:08:25 +02:00
antirez 5b5e65203f Sentinel: check Slave INFO state more often when disconnected.
During the initial handshake with the master a slave will report to have
a very high disconnection time from its master (since technically it was
disconnected since forever, so the current UNIX time in seconds is
reported).

However when the slave is connected again the Sentinel may re-scan the
INFO output again only after 10 seconds, which is a long time. During
this time Sentinels will consider this instance unable to failover, so
a useless delay is introduced.

Actaully this hardly happened in the practice because when a slave's
master is down, the INFO period for slaves changes to 1 second. However
when a manual failover is attempted immediately after adding slaves
(like in the case of the Sentinel unit test), this problem may happen.

This commit changes the INFO period to 1 second even in the case the
slave's master is not down, but the slave reported to be disconnected
from the master (by publishing, last time we checked, a master
disconnection time field in INFO).

This change is required as a result of an unrelated change in the
replication code that adds a small delay in the master-slave first
synchronization.

antirez 21cffc2681 Avoid simultaneous RDB and AOF child process.
This patch, written in collaboration with Oran Agra (@oranagra) is a companion
to 780a8b1. Together the two patches should avoid that the AOF and RDB saving
processes can be spawned at the same time. Previously conditions that
could lead to two saving processes at the same time were:

1. When AOF is enabled via CONFIG SET and an RDB saving process is
   already active.

2. When the SYNC command decides to start an RDB saving process ASAP in
   order to serve a new slave that cannot partially resynchronize (but
   only if we have a disk target for replication, for diskless
   replication there is not such a problem).

Condition "1" is not very severe but "2" can happen often and is
definitely good at degrading Redis performances in an unexpected way.

The two commits have the effect of always spawning RDB savings for
replication in replicationCron() instead of attempting to start an RDB
save synchronously. Moreover when a BGSAVE or AOF rewrite must be
performed, they are instead just postponed using flags that will try to
perform such operations ASAP.

Finally the BGSAVE command was modified in order to accept a SCHEDULE
option so that if an AOF rewrite is in progress, when this option is
given, the command no longer returns an error, but instead schedules an
RDB rewrite operation for when it will be possible to start it.

antirez 026f9fc7b0 Sentinel: fix cross-master Sentinel address update.
This commit both fixes the crash reported with issue #3364 and
also properly closes the old links after the Sentinel address for the
other masters gets updated.

The two problems where:

1. The Sentinel that switched address may not monitor all the masters,
   it is possible that there is no match, and the 'match' variable is
   NULL. Now we check for no match and 'continue' to the next master.

2. By ispecting the code because of issue "1" I noticed that there was a
   problem in the code that disconnects the link of the Sentinel that
   needs the address update. Basically link->disconnected is non-zero
   even if just *a single link* (cc -- command link or pc -- pubsub
   link) are disconnected, so to check with if (link->disconnected)
   in order to close the links risks to leave one link connected.

I was able to manually reproduce the crash at "1" and verify that the
commit resolves the issue.

antirez f578f08544 In Redis RDB check: initial POC.
So far we used an external program (later executed within Redis) and
parser in order to check RDB files for correctness. This forces, at each
RDB format update, to have two copies of the same format implementation
that are hard to keep in sync. Morover the former RDB checker only
checked the very high-level format of the file, without actually trying
to load things in memory. Certain corruptions can only be handled by
really loading key-value pairs.

This first commit attempts to unify the Redis RDB loadig code with the
task of checking the RDB file for correctness. More work is needed but
it looks like a sounding direction so far.

antirez 704196790e Fix quicklistReplaceAtIndex() by updating the quicklist ziplist size.
The quicklist takes a cached version of the ziplist representation size
in bytes. The implementation must update this length every time the
underlying ziplist changes. However quicklistReplaceAtIndex() failed to
fix the length.

During LSET calls, the size of the ziplist blob and the cached size
inside the quicklist diverged. Later, when this size is used in an
authoritative way, for example during nodes splitting in order to copy
the nodes, we end with a duplicated node that may contain random
garbage.

This commit should fix issue #3343, however several problems were found
reviewing the quicklist.c code in search of this bug that should be
addressed soon or later.

For example:

1. To take a cached ziplist length is fragile since failing to update it
leads to this kind of issues.

2. The node splitting code needs auditing. For example it works just for
a side effect of ziplistDeleteRange() to be able to cope with a wrong
count of elements to remove. The code inside quicklist.c assumes that
-1 means "delete till the end" while actually it's just a count of how
many elements to delete, and is an unsigned count. So -1 gets converted
into the maximum integer, and just by chance the ziplist code stops
deleting elements after there are no more to delete.

3. Node splitting is extremely inefficient, it copies the node and
removes elements from both nodes even when actually there is to move a
single entry from one node to the other, or when the new resulting node
is empty at all so there is nothing to copy but just to create a new
node.

However at least for Redis 3.2 to introduce fresh code inside
quicklist.c may be even more risky, so instead I'm writing a better
fuzzy tester to stress the internals a bit more in order to anticipate
other possible bugs.

This bug was found using a fuzzy tester written after having some clue
about where the bug could be. The tester eventually created a ~2000
commands sequence able to always crash Redis. I wrote a better version
of the tester that searched for the smallest sequence that could crash
Redis automatically. Later this smaller sequence was minimized by
removing random commands till it still crashed the server. This resulted
into a sequence of 7 commands. With this small sequence it was just a
matter of filling the code with enough printf() to understand enough
state to fix the bug.

antirez 6ad0371c9b Fix Sentinel pending commands counting.
This bug most experienced effect was an inability of Redis to
reconfigure back old masters to slaves after they are reachable again
after a failover. This was due to failing to reset the count of the
pending commands properly, so the master appeared fovever down.

Was introduced in Redis 3.2 new Sentinel connection sharing feature
which is a lot more complex than the 3.0 code, but more scalable.

Many thanks to people reporting the issue, and especially to
@sskorgal for investigating the issue in depth.

Hopefully closes #3285.

antirez 58f1d446c3 redis-cli: really connect to the right server.
I recently introduced populating the autocomplete help array with the
COMMAND command if available. However this was performed before parsing
the arguments, defaulting to instance 6379. After the connection is
performed it remains stable.

The effect is that if there is an instance running on port 6339,
whatever port you specify is ignored and 6379 is connected to instead.
The right port will be selected only after a reconnection.

Close #3314.

antirez f592b4d317 RESTORE: accept RDB dumps with older versions.
Reference issue #3218.

Checking the code I can't find a reason why the original RESTORE
code was so opinionated about restoring only the current version. The
code in to `rdb.c` appears to be capable as always to restore data from
older versions of Redis, and the only places where it is needed the
current version in order to correctly restore data, is while loading the
opcodes, not the values itself as it happens in the case of RESTORE.

For the above reasons, this commit enables RESTORE to accept older
versions of values payloads.

I'm the author of this line but I can't see a good reason for it to
don't be a typo, a step of 26 should be valid with 52 bits per
coordinate, moreover the line was:

    if (step > 26) step = 25;

So a step of 26 was actually already used, except when one of 27 was
computed (which is invalid) only then it was trimmed to 25 instead of
26.

antirez 38cf2bd257 Cluster regression test for #3043.
The test works but is very slow so far, since it involves resharding
1/5 of all the cluster slots from master 0 to the other 4 masters and
back into the original master.
2016-05-02 18:36:13 +02:00
antirez 7b618823c1 New masters with slots are now targets of migration if others are.
This fixes issue #3043.

Before this fix, after a complete resharding of a master slots
to other nodes, the master remains empty and the slaves migrate away
to other masters with non-zero nodes. However the old master now empty,
is no longer considered a target for migration, because the system has
no way to tell it had slaves in the past.

This fix leaves the algorithm used in the past untouched, but adds a
new rule. When a new or old master which is empty and without slaves,
are assigend with their first slot, if other masters in the cluster have
slaves, they are automatically considered to be targets for replicas
migration.

The problem with the old implementation is that, the time returned by
a timer event (that is the time after it want to run again) is added
to the event *start time*. So if the event takes, in order to run, more
than the time it says it want to be scheduled again for running, an
infinite loop is triggered.

antirez 761a772871 BITFIELD command initial implementation.
The new bitfield command is an extension to the Redis bit operations,
where not just single bit operations are performed, but the array of
bits composing a string, can be addressed at random, not aligned
offsets, with any width unsigned and signed integers like u8, s5, u10
(up to 64 bit signed integers and 63 bit unsigned integers).

The BITFIELD command supports subcommands that can SET, GET, or INCRBY
those arbitrary bit counters, with multiple overflow semantics.

Trivial and credits:

A similar command was imagined a few times in the past, but for
some reason looked a bit far fetched or not well specified.
Finally the command was proposed again in a clear form by
Yoav Steinberg from Redis Labs, that proposed a set of commands on
arbitrary sized integers stored at bit offsets.

Starting from this proposal I wrote an initial specification of a single
command with sub-commands similar to what Yoav envisioned, using short
names for types definitions, and adding control on the overflow.

This commit is the resulting implementation.

CLUSTER SLOTS now includes IDs in the nodes description associated with

NODES, that is not a stable API and may change frequently depending on
Redis Cluster future requirements.

antirez 6bd409d0c8 Sentinel: improve handling of known Sentinel instances.
1. Bug #3035 is fixed (NULL pointer access). This was happening with the
   folling set of conditions:

* For some reason one of the Sentinels, let's call it Sentinel_A, changed ID (reconfigured from scratch), but is as the same address at which it used to be.

* Sentinel_A performs a failover and/or has a newer configuration compared to another Sentinel, that we call, Sentinel_B.

* Sentinel_B receives an HELLO message from Sentinel_A, where the address and/or ID is mismatched, but it is reporting a newer configuration for the master they are both monitoring.

2. Sentinels now must have an ID otherwise they are not loaded nor persisted in the configuration. This allows to have conflicting Sentinels with the same address since now the master->sentinels dictionary is indexed by Sentinel ID.

3. The code now detects if a Sentinel is annoucing itself with an IP/port pair already busy (of another Sentinel). The old Sentinel that had the same port/pair is set as having port 0, that means, the address is invalid. We may discover the right address later via HELLO messages.

antirez 7f97d75ef6 Cluster: fix missing ntohs() call to access gossip section port. 2016-01-26 14:20:08 +01:00
antirez bd998b7d46 Better address udpate strategy when processing gossip sections.
The change covers the case where:

1. There is a node we can't reach (in fail or pfail state).
2. We see a different address for this node, in the gossip section sent
to us by a node that, instead, is able to talk with the node we cannot
talk to.

In this case it's a good bet to switch to the address reported by this
node, since there was an address switch and it is able to talk with the
node and we are not.

However previosuly this was done in a dangerous way, by initiating an
handshake. The handshake, using the MEET packet, forces the receiver to
join our cluster, and this is not a good idea. If the node in question
really just switched address, but is the same node, it already knows about
us, so we just need to perform an address update and a reconnection.

So with this commit instead we just update the address of the node,
release the node link if any, and attempt to reconnect in the next
clusterCron() cycle.

The commit also improves debugging messages printed by Cluster during
address or ID switches.

antirez c9889461aa Cluster: fix setting nodes slaveof pointer to NULL on node release.
With this commit we preserve the list of nodes that have .slaveof set
to the node, even when the node is turned into a slave, and make sure to
fix the .slaveof pointers to NULL when a node is freed from memory,
regardless of the fact it's a slave or a master.

Basically we try to remember the logical master in the current
configuration even if the logical master advertised it as a slave
already. However we still remember the associations, so that when a node
is freed we can fix them.

This should fix issue #3002.

This fix, provided by Paul Kulchenko (@pkulchenko), allows the Lua

Lua can't parse the above if the string does not end with a newline, so
now a final newline is always added automatically. This does not change
the SHA1 of scripts since the SHA1 is computed on the body we pass to
EVAL, without the other code we add to register the function.

antirez 273c49e726 New security feature: Redis protected mode.
An exposed Redis instance on the internet can be cause of serious
issues. Since Redis, by default, binds to all the interfaces, it is easy
to forget an instance without any protection layer, for error.

Protected mode try to address this feature in a soft way, providing a
layer of protection, but giving clues to Redis users about why the
server is not accepting connections.

When protected mode is enabeld (the default), and if there are no
minumum hints about the fact the server is properly configured (no
"bind" directive is used in order to restrict the server to certain
interfaces, nor a password is set), clients connecting from external
intefaces are refused with an error explaining what to do in order to
fix the issue.

Clients connecting from the IPv4 and IPv6 lookback interfaces are still
accepted normally, similarly Unix domain socket connections are not
restricted in any way.

They may be expired or deleted between the GETKEYSINSLOT call and the
MIGRATE call. Otherwise this causes an error during migrations with
redis-trib (or equivalent cluster management tools).

2015-12-17 17:53:29 +01:00
antirez 7a7e46b22f Fix a race that may lead to the active (slave) client to be freed.
In issue #2948 a crash was reported in processCommand(). Later Oran Agra
(@oranagra) traced the bug (in private chat) in the following sequence
of events:

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

There are different possible fixes:

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

antirez fc00042ef9 Hopefully better memory test on crash.
The old test, designed to do a transformation on the bits that was
invertible, in order to avoid touching the original memory content, was
not effective as it was redis-server --test-memory. The former often
reported OK while the latter was able to spot the error.

So the test was substituted with one that may perform better, however
the new one must backup the memory tested, so it tests memory in small
pieces. This limits the effectiveness because of the CPU caches. However
some attempt is made in order to trash the CPU cache between the fill
and the check stages, but not for the addressing test unfortunately.

We'll see if this test will be able to find errors where the old failed.

antirez 87615a81ab Cluster: redis-trib: use variadic MIGRATE.
We use the new variadic/pipelined MIGRATE for faster migration.
Testing is not easy because to see the time it takes for a slot to be
migrated requires a very large data set, but even with all the overhead
of migrating multiple slots and to setup them properly, what used to
take 4 seconds (1 million keys, 200 slots migrated) is now 1.6 which is
a good improvement. However the improvement can be a lot larger if:

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

antirez 6b8a6c2ad9 Cluster: replica migration with delay.
We wait a fixed amount of time (5 seconds currently) much greater than
the usual Cluster node to node communication latency, before migrating.
This way when a failover occurs, before detecting the new master as a
target for migration, we give the time to its natural slaves (the slaves
of the failed over master) to announce they switched to the new master,
preventing an useless migration operation.

antirez 7399195c3f Cluster: more reliable migration tests.
The old version was modeled with two failovers, however after the first
it is possible that another slave will migrate to the new master, since
for some time the new master is not backed by any slave. Probably there
should be some pause after a failover, before the migration. Anyway the
test is simpler in this way, and depends less on timing.

antirez db65f6d374 Fix replicas migration by adding a new flag.
Some time ago I broken replicas migration (reported in #2924).
The idea was to prevent masters without replicas from getting replicas
because of replica migration, I remember it to create issues with tests,
but there is no clue in the commit message about why it was so
undesirable.

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

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

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

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

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

antirez 1cc7a45440 Handle wait3() errors.
My guess was that wait3() with WNOHANG could never return -1 and an
error. However issue #2897 may possibly indicate that this could happen
under non clear conditions. While we try to understand this better,
better to handle a return value of -1 explicitly, otherwise in the
case a BGREWRITE is in progress but wait3() returns -1, the effect is to
match the first branch of the if/else block since server.rdb_child_pid
is -1, and call backgroundSaveDoneHandler() without a good reason, that
will, in turn, crash the Redis server with an assertion.

antirez b9429fd821 Lua debugger: use sds_malloc() to allocate eval cli array.
Redis-cli handles the debugger "eval" command in a special way since
sdssplitargs() would not be ok: we need to send the Redis debugger the
whole Lua script without any parsing. However in order to later free the
argument vector inside redis-cli using just sdsfreesplitres(), we need
to allocate the array of SDS pointers using the same allocator SDS is
using, that may differ to what Redis is using.

So now a newer version of SDS exports sds_malloc() and other allocator
functions to give access, to the program it is linked to, the allocator
used internally by SDS.

It's handly to just eval "5+5" without the return and see it printed on
the screen as result. However prepending "return" does not always result
into valid Lua code. So what we do is to exploit a common Lua community
trick of trying to compile with return prepended, and if compilation
fails then it's not an expression that can be returned, so we try again
without prepending "return". Works great apparently.

the fuction), but is more correct conceptually, and may be used in
other contexts.

antirez a1d1ca1416 Lua script selective replication WIP. 2015-10-30 12:08:20 +01:00
antirez cbbfaf6ad3 Scripting: single commands replication mode implemented.
By calling redis.replicate_commands(), the scripting engine of Redis
switches to commands replication instead of replicating whole scripts.
This is useful when the script execution is costly but only results in a
few writes performed to the dataset.

Morover, in this mode, it is possible to call functions with side
effects freely, since the script execution does not need to be
deterministic: anyway we'll capture the outcome from the point of view
of changes to the dataset.

In this mode math.random() returns different sequences at every call.

If redis.replicate_commnads() is not called before any other write, the
command returns false and sticks to whole scripts replication instead.

antirez de4d6caf55 CLIENT REPLY command implemented: ON, OFF and SKIP modes.
Sometimes it can be useful for clients to completely disable replies
from the Redis server. For example when the client sends fire and forget
commands or performs a mass loading of data, or in caching contexts
where new data is streamed constantly. In such contexts to use server
time and bandwidth in order to send back replies to clients, which are
going to be ignored, is a shame.

Multiple mechanisms are possible to implement such a feature. For
example it could be a feature of MULTI/EXEC, or a command prefix
such as "NOREPLY SADD myset foo", or a different mechanism that allows
to switch on/off requests using the CLIENT command.

The MULTI/EXEC approach has the problem that transactions are not
strictly part of the no-reply semantics, and if we want to insert a lot
of data in a bulk way, creating a huge MULTI/EXEC transaction in the
server memory is bad.

The prefix is the best in this specific use case since it does not allow
desynchronizations, and is pretty clear semantically. However Redis
internals and client libraries are not prepared to handle this
currently.

So the implementation uses the CLIENT command, providing a new REPLY
subcommand with three options:

    CLIENT REPLY OFF disables the replies, and does not reply itself.
    CLIENT REPLY ON re-enables the replies, replying +OK.
    CLIENT REPLY SKIP only discards the reply of the next command, and
                      like OFF does not reply anything itself.

The reason to add the SKIP command is that it allows to have an easy
way to send conceptually "single" commands that don't need a reply
as the sum of two pipelined commands:

    CLIENT REPLY SKIP
    SET key value

Note that CLIENT REPLY ON replies with +OK so it should be used when
sending multiple commands that don't need a reply. However since it
replies with +OK the client can check that the connection is still
active and all the previous commands were received.

This is currently just into Redis "unstable" so the proposal can be
modified or abandoned based on users inputs.

content to write was written.

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

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

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>].
The following environment variables (not a definitive list) impact configure's
behavior:
