charsyam b37512a28f Fix AOF bug: expire could be removed from key on AOF rewrite. 
There was a race condition in the AOF rewrite code that, with bad enough
timing, could cause a volatile key just about to expire to be turned
into a non-volatile key. The bug was never reported to cause actualy
issues, but was found analytically by an user in the Redis mailing list:

https://groups.google.com/forum/?fromgroups=#!topic/redis-db/Kvh2FAGK4Uk

This commit fixes issue #1079.

antirez 4f38d03254 Sentinel: changes to tilt mode. 
Tilt mode was too aggressive (not processing INFO output), this
resulted in a few problems:

1) Redirections were not followed when in tilt mode. This opened a
   window to misinform clients about the current master when a Sentinel
   was in tilt mode and a fail over happened during the time it was not
   able to update the state.

2) It was possible for a Sentinel exiting tilt mode to detect a false
   fail over start, if a slave rebooted with a wrong configuration
   about at the same time. This used to happen since in tilt mode we
   lose the information that the runid changed (reboot).

   Now instead the Sentinel in tilt mode will still remove the instance
   from the list of slaves if it changes state AND runid at the same
   time.

Both are edge conditions but the changes should overall improve the
reliability of Sentinel.

antirez 59ff2fe9a4 Sentinel: more sensible delay in master demote after tilt. 2013-04-30 15:09:31 +02:00
antirez fb0d08e35f Sentinel: only demote old master into slave under certain conditions. 
We used to always turn a master into a slave if the DEMOTE flag was set,
as this was a resurrecting master instance.

However the following race condition is possible for a Sentinel that
got partitioned or internal issues (tilt mode), and was not able to
refresh the state in the meantime:

1) Sentinel X is running, master is instance "A".
3) "A" fails, sentinels will promote slave "B" as master.
2) Sentinel X goes down because of a network partition.
4) "A" returns available, Sentinels will demote it as a slave.
5) "B" fails, other Sentinels will promote slave "A" as master.
6) At this point Sentinel X comes back.

When "X" comes back he thinks that:

"B" is the master.
"A" is the slave to demote.

We want to avoid that Sentinel "X" will demote "A" into a slave.
We also want that Sentinel "X" will detect that the conditions changed
and will reconfigure itself to monitor the right master.

There are two main ways for the Sentinel to reconfigure itself after
this event:

1) If "B" is reachable and already configured as a slave by other
sentinels, "X" will perform a redirection to "A".
2) If there are not the conditions to demote "A", the fact that "A"
reports to be a master will trigger a failover detection in "X", that
will end into a reconfiguraiton to monitor "A".

However if the Sentinel was not reachable, its state may not be updated,
so in case it titled, or was partiitoned from the master instance of the
slave to demote, the new implementation waits some time (enough to
guarantee we can detect the new INFO, and new DOWN conditions).

If after some time still there are not the right condiitons to demote
the instance, the DEMOTE flag is cleared.

antirez 34a57a5b52 Sentinel: always redirect on master->slave transition. 
Sentinel redirected to the master if the instance changed runid or it
was the first time we got INFO, and a role change was detected from
master to slave.

While this is a good idea in case of slave->master, since otherwise we
could detect a failover without good reasons just after a reboot with a
slave with a wrong configuration, in the case of master->slave
transition is much better to always perform the redirection for the
following reasons:

1) A Sentinel may go down for some time. When it is back online there is
no other way to understand there was a failover.
2) Pointing clients to a slave seems to be always the wrong thing to do.
3) There is no good rationale about handling things differently once an
instance is rebooted (runid change) in that case.

antirez 40861516ac redis-cli: raise error on bad command line switch. 
Previously redis-cli never tried to raise an error when an unrecognized
switch was encountered, as everything after the initial options is to be
transmitted to the server.

However this is too liberal, as there are no commands starting with "-".
So the new behavior is to produce an error if there is an unrecognized
switch starting with "-". This should not break past redis-cli usages
but should prevent broken options to be silently discarded.

As far the first token not starting with "-" is encountered, all the
rest is considered to be part of the command, so you cna still use
strings starting with "-" as values, like in:

antirez ed2d988192 Throttle BGSAVE attempt on saving error. 
When a BGSAVE fails, Redis used to flood itself trying to BGSAVE at
every next cron call, that is either 10 or 100 times per second
depending on configuration and server version.

This commit does not allow a new automatic BGSAVE attempt to be
performed before a few seconds delay (currently 5).

This avoids both the auto-flood problem and filling the disk with
logs at a serious rate.

The five seconds limit, considering a log entry of 200 bytes, will use
less than 4 MB of disk space per day that is reasonable, the sysadmin
should notice before of catastrofic events especially since by default
Redis will stop serving write queries after the first failed BGSAVE.

This fixes issue #849

antirez 611dcb56ee Transactions: propagate MULTI/EXEC only when needed. 
MULTI/EXEC is now propagated to the AOF / Slaves only once we encounter
the first command that is not a read-only one inside the transaction.

The old behavior was to always propagate an empty MULTI/EXEC block when
the transaction was composed just of read only commands, or even
completely empty. This created two problems:

1) It's a bandwidth waste in the replication link and a space waste
   inside the AOF file.

2) We used to always increment server.dirty to force the propagation of
   the EXEC command, resulting into triggering RDB saves more often
   than needed.

Note: even read-only commands may also trigger writes that will be
propagated, when we access a key that is found expired and Redis will
synthesize a DEL operation. However there is no need for this to stay
inside the transaction itself, but only to be ordered.

So for instance something like:

    MULTI
    GET foo
    SET key zap
    EXEC

May be propagated into:

    DEL foo
    MULTI
    SET key zap
    EXEC

While the DEL is outside the transaction, the commands are delivered in
the right order and it is not possible for other commands to be inserted
between DEL and MULTI.

Redis-tools is a connection of tools no longer mantained that was
intented as a way to economically make sense of Redis in the pre-vmware
sponsorship era. However there was a nice redis-stat utility, this
commit imports one of the functionalities of this tool here in redis-cli
as it seems to be pretty useful.

Usage: redis-cli --stat

The output is similar to vmstat in the format, but with Redis specific
stuff of course.

From the point of view of the monitored instance, only INFO is used in
order to grab data.

antirez 48f4f77189 activeExpireCycle() smarter with many DBs and under expire pressure. 
activeExpireCycle() tries to test just a few DBs per iteration so that
it scales if there are many configured DBs in the Redis instance.
However this commit makes it a bit smarter when one a few of those DBs
are under expiration pressure and there are many many keys to expire.

What we do is to remember if in the last iteration had to return because
we ran out of time. In that case the next iteration we'll test all the
configured DBs so that we are sure we'll test again the DB under
pressure.

Before of this commit after some mass-expire in a given DB the function
tested just a few of the next DBs, possibly empty, a few per iteration,
so it took a long time for the function to reach again the DB under
pressure. This resulted in a lot of memory being used by already expired
keys and never accessed by clients.

antirez 13f84841b5 activeExpireCycle(): process only a small number of DBs per iteration. 
This small number of DBs is set to 16 so actually in the default
configuraiton Redis should behave exactly like in the past.
However the difference is that when the user configures a very large
number of DBs we don't do an O(N) operation, consuming a non trivial
amount of CPU per serverCron() iteration.

This is the first step to lower the CPU usage when many databases are

antirez aec5ea5d07 serverCron() frequency is now a runtime parameter (was REDIS_HZ). 
REDIS_HZ is the frequency our serverCron() function is called with.
A more frequent call to this function results into less latency when the
server is trying to handle very expansive background operations like
mass expires of a lot of keys at the same time.

Redis 2.4 used to have an HZ of 10. This was good enough with almost
every setup, but the incremental key expiration algorithm was working a
bit better under *extreme* pressure when HZ was set to 100 for Redis
2.6.

However for most users a latency spike of 30 milliseconds when million
of keys are expiring at the same time is acceptable, on the other hand a
default HZ of 100 in Redis 2.6 was causing idle instances to use some
CPU time compared to Redis 2.4. The CPU usage was in the order of 0.3%
for an idle instance, however this is a shame as more energy is consumed
by the server, if not important resources.

This commit introduces HZ as a runtime parameter, that can be queried by
INFO or CONFIG GET, and can be modified with CONFIG SET. At the same
time the default frequency is set back to 10.

In this way we default to a sane value of 10, but allows users to
easily switch to values up to 500 for near real-time applications if
needed and if they are willing to pay this small CPU usage penalty.

 2013-03-06 16:50:56 +01:00
antirez e7a61d287e API to lookup commands with their original name. 
A new server.orig_commands table was added to the server structure, this
contains a copy of the commant table unaffected by rename-command
statements in redis.conf.

A new API lookupCommandOrOriginal() was added that checks both tables,
new first, old later, so that rewriteClientCommandVector() and friends
can lookup commands with their new or original name in order to fix the
client->cmd pointer when the argument vector is renamed.

This fixes the segfault of issue #986, but does not fix a wider range of
problems resulting from renaming commands that actually operate on data
and are registered into the AOF file or propagated to slaves... That is
command renaming should be handled with care.

charsyam 45b1b2f7ad Turn off TCP_NODELAY on the slave socket after SYNC. 
Further details from @antirez:

It was reported by @StopForumSpam on Twitter that the Redis replication
link was strangely using multiple TCP packets for multiple commands.
This wastes a lot of bandwidth and is due to the TCP_NODELAY option we
enable on the socket after accepting a new connection.

However the master -> slave channel is a one-way channel since Redis
replication is asynchronous, so there is no point in trying to reduce
the latency, we should aim to reduce the bandwidth. For this reason this
commit introduces the ability to disable the nagle algorithm on the
socket after a successful SYNC.

This feature is off by default because the delay can be up to 40
milliseconds with normally configured Linux kernels.

antirez 742e580f40 UNSUBSCRIBE and PUNSUBSCRIBE: always provide a reply. 
UNSUBSCRIBE and PUNSUBSCRIBE commands are designed to mass-unsubscribe
the client respectively all the channels and patters if called without
arguments.

However when these functions are called without arguments, but there are
no channels or patters we are subscribed to, the old behavior was to
don't reply at all.

This behavior is broken, as every command should always reply.
Also it is possible that we are no longer subscribed to a channels but we
are subscribed to patters or the other way around, and the client should
be notified with the correct number of subscriptions.

Also it is not pretty that sometimes we did not receive a reply at all
in a redis-cli session from these commands, blocking redis-cli trying
to read the reply.

This fixes issue #714.

antirez da540228d8 Whitelist SIGUSR1 to avoid auto-triggering errors. 
This commit fixes issue #875 that was caused by the following events:

1) There is an active child doing BGSAVE.
2) flushall is called (or any other condition that makes Redis killing
the saving child process).
3) An error is sensed by Redis as the child exited with an error (killed
by a singal), that stops accepting write commands until a BGSAVE happens
to be executed with success.

Whitelisting SIGUSR1 and making sure Redis always uses this signal in
order to kill its own children fixes the issue.

Nathan Parry 0f4dbd9a11 redis-cli --rdb fails if server sends a ping 
Redis pings slaves in "pre-synchronization stage" with newlines. (See
https://github.com/antirez/redis/blob/2.6.9/src/replication.c#L814)
However, redis-cli does not expect this - it sees the newline as the end
of the bulk length line, and ends up returning 0 as bulk the length.
This manifests as the following when running redis-cli:

    $ ./src/redis-cli --rdb some_file
    SYNC sent to master, writing 0 bytes to 'some_file'
    Transfer finished with success.

With this commit, we just ignore leading newlines while reading the bulk
length line.

To reproduce the problem, load enough data into Redis so that the
preparation of the RDB snapshot takes long enough for a ping to occur
while redis-cli is waiting for the data.

antirez c5f23ca79b CLIENT GETNAME and CLIENT SETNAME introduced. 
Sometimes it is much simpler to debug complex Redis installations if it
is possible to assign clients a name that is displayed in the CLIENT
LIST output.

This is the case, for example, for "leaked" connections. The ability to
provide a name to the client makes it quite trivial to understand what
is the part of the code implementing the client not releasing the
resources appropriately.

Behavior:

    CLIENT SETNAME: set a name for the client, or remove the current
                    name if an empty name is set.
    CLIENT GETNAME: get the current name, or a nil.
    CLIENT LIST: now displays the client name if any.

Thanks to Mark Gravell for pushing this idea forward.

Issue #828 shows how Redis was not correctly undoing a non-blocking
connection attempt with the previous master when the master was set to a

This was also a result of lack of refactoring, so now there is a
function to cancel the non blocking handshake with the master.
The new function is now used when SLAVEOF NO ONE is called or when
SLAVEOF is used to set the master to a different address.

I simply forgot to free the new allocated dictionary in the client

testing memory leaks. This problem was also fixed.

antirez 54b08c86a6 Blocking POP: use a dictionary to store keys clinet side. 
To store the keys we block for during a blocking pop operation, in the
case the client is blocked for more data to arrive, we used a simple
linear array of redis objects, in the blockingState structure:

    robj **keys;
    int count;

However in order to fix issue #801 we also use a dictionary in order to
avoid to end in the blocked clients queue for the same key multiple
times with the same client.

The dictionary was only temporary, just to avoid duplicates, but since
we create / destroy it there is no point in doing this duplicated work,
so this commit simply use a dictionary as the main structure to store
the keys we are blocked for. So instead of the previous fields we now
just have:

    dict *keys;

This simplifies the code and reduces the work done by the server during
a blocking POP operation.

antirez cac49a9031 Client should not block multiple times on the same key. 
Sending a command like:

BLPOP foo foo foo foo 0

Resulted into a crash before this commit since the client ended being
inserted in the waiting list for this key multiple times.
This resulted into the function handleClientsBlockedOnLists() to fail
because we have code like that:

    if (de) {
        list *clients = dictGetVal(de);
        int numclients = listLength(clients);

        while(numclients--) {
            listNode *clientnode = listFirst(clients);

            /* server clients here... */
        }
    }

The code to serve clients used to remove the served client from the
waiting list, so if a client is blocking multiple times, eventually the
call to listFirst() will return NULL or worse will access random memory
since the list may no longer exist as it is removed by the function
unblockClientWaitingData() if there are no more clients waiting for this
list.

To avoid making the rest of the implementation more complex, this commit
modifies blockForKeys() so that a client will be put just a single time
into the waiting list for a given key.

Since it is Saturday, I hope this fixes issue #801.

CRITICAL: There is a critical bug affecting MOST USERS. Upgrade ASAP.
--------------------------------------------------------------------------------
--[ Redis 2.6.14 ] Release date: 20 Jun 2013
UPGRADE URGENCY: HIGH because of the following two issues:
* Lua scripting + Replication + AOF in slaves problem (see Issue #1164).

* [FIX] AOF bug: expire could be removed from key on AOF rewrite.
* [FIX] Allow writes from scripts called by AOF loading in read-only slaves.
* [FIX] Sentinel: parse new verison of INFO replication output correctly.
* [NEW] Reset masterauth if an empty string is configured.
--[ Redis 2.6.13 ]
UPGRADE URGENCY: MODERATE, nothing very critical but upgrading is suggested
if you experienced:
1) Strange issues with Lua scripting.
2) Not reconfigured reappearing master using Sentinel.
3) Server continusly trying to save on save error.
This version of Redis may also help with AOF and slow / busy
disks and latency issues.
* [FIX] Throttle BGSAVE attempt on saving error.
* [FIX] redis-cli: raise error on bad command line switch.
* [FIX] Redis/Jemalloc Gitignore were too aggressive.

* [FIX] Sentinel: always redirect on master->slave transition.
* [FIX] Lua updated to version 5.1.5. Fixes rare scripting issues.
* [NEW] AOF: improved latency figures with slow/busy disks.
* [NEW] Sentinel: turn old master into a slave when it comes back.
* [NEW] More explicit panic message on out of memory.
* [NEW] redis-cli: --latency-history mode implemented.
--[ Redis 2.6.12 ]
UPGRADE URGENCY: MODERATE, nothing very critical but a few non trivial bugs.
* [BUGFIX] redis-cli --bigkeys: don't crash with empty DB.

* [BUGFIX] Allow SELECT while loading the DB.
* [BUGFIX] Don't replicate/AOF an empty MULTI/EXEC if the transaction
is empty or containing just read-only commands.
* [BUGFIX] EXPIRE should not be able to resurrect keys (see issue #1026).
* [IMPROVED] Extended SET back ported from Redis 2.8 / unstable
See http://redis.io/commands/set for more information.

Redis Manifesto
===============
1 - A DSL for Abstract Data Types. Redis is a DSL (Domain Specific Language) that manipulates abstract data types and implemented as a TCP daemon. Commands manipulate a key space where keys are binary-safe strings and values are different kinds of abstract data types. Every data type represents an abstract version of a fundamental data structure. For instance Redis Lists are an abstract representation of linked lists. In Redis, the essence of a data type isn't just the kind of operations that the data types support, but also the space and time complexity of the data type and the operations performed upon it.

operations performed upon it.
2 - Memory storage is #1. The Redis data set, composed of defined key-value pairs, is primarily stored in the computer's memory. The amount of memory in all kinds of computers, including entry-level servers, is increasing significantly each year. Memory is fast, and allows Redis to have very predictable performance. Datasets composed of 10k or 40 millions keys will perform similarly. Complex data types like Redis Sorted Sets are easy to implement and manipulate in memory with good performance, making Redis very simple. Redis will continue to explore alternative options (where data can be optionally stored on disk, say) but the main goal of the project remains the development of an in-memory database.

3 - Fundamental data structures for a fundamental API. The Redis API is a direct consequence of fundamental data structures. APIs can often be arbitrary but not an API that resembles the nature of fundamental data structures. If we ever meet intelligent life forms from another part of the universe, they'll likely know, understand and recognize the same basic data structures we have in our computer science books. Redis will avoid intermediate layers in API, so that the complexity is obvious and more complex operations can be performed as the sum of the basic operations.

4 - Code is like a poem; it's not just something we write to reach some practical result. Sometimes people that are far from the Redis philosophy suggest using other code written by other authors (frequently in other languages) in order to implement something Redis currently lacks. But to us this is like if Shakespeare decided to end Enrico IV using the Paradiso from the Divina Commedia. Is using any external code a bad idea? Not at all. Like in "One Thousand and One Nights" smaller self contained stories are embedded in a bigger story, we'll be happy to use beautiful self contained libraries when needed. At the same time, when writing the Redis story we're trying to write smaller stories that will fit in to other code.

5 - We're against complexity. We believe designing systems is a fight against complexity. We'll accept to fight the complexity when it's worthwhile but we'll try hard to recognize when a small feature is not worth 1000s of lines of code. Most of the time the best way to fight complexity is by not creating it at all.

6 - Two levels of API. The Redis API has two levels: 1) a subset of the API fits naturally into a distributed version of Redis and 2) a more complex API that supports multi-key operations. Both are useful if used judiciously but there's no way to make the more complex multi-keys API distributed in an opaque way without violating our other principles. We don't want to provide the illusion of something that will work magically when actually it can't in all cases. Instead we'll provide commands to quickly migrate keys from one instance to another to perform multi-key operations and expose the tradeoffs to the user.
7 - We optimize for joy. We believe writing code is a lot of hard work, and the only way it can be worth is by enjoying it. When there is no longer joy in writing code, the best thing to do is stop. To prevent this, we'll avoid taking paths that will make Redis less of a joy to develop.

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"

Redis on Windows 2.6 prototype
===
## What's new in this release
- This is a port for Windows based on Redis 2.6. The latest version merged in 2.6.12.
- The port is similar to the port of Redis 2.4, including the same background saving technology.
- There is support for x64 version as well as 32 bit versions.
- For the 64 bit version, there is a limit of 2^32 objects in a structure, and a max length of 2^32 for any object
- Version number now 2.6.8-pre2 to indicate prerelease and to enable changing
- Version 2.6.8-pre2 fixes several failures that existed in 2.6.8-pre1. Most of these were related to handling opening and closing of non-blocking sockets.
- The unit/protocol desync test is updated to use nonblocking socket and now works on Windows
- The binaries (unsigned) have been moved to the root to make them easier to find. Previously they were under msvs.
- Signed binaries can be downloaded using Nuget.
##Acknowledgements
Special thanks to Dušan Majkic (https://github.com/dmajkic, https://github.com/dmajkic/redis/) for his project on GitHub that gave us the opportunity to quickly learn some on the intricacies of Redis code. His project also helped us to build our prototype quickly.
## Repo branches
- 2.6: This is the branch for the Windows Redis port based on Redis 2.6.
- 2.4: This branch has the Windows Redis port based on Redis 2.4.
## How to build Redis using Visual Studio
You can use the free Express Edition available at http://www.microsoft.com/visualstudio/en-us/products/2010-editions/visual-cpp-express.
- Open the solution file msvs\redisserver.sln in Visual Studio 10, select platform (win32 or x64) and build.
This should create the following executables in the msvs\$(Configuration) folder:
- redis-server.exe
- redis-benchmark.exe
- redis-cli.exe
- redis-check-dump.exe
- redis-check-aof.exe
For your convenience all binaries are be available in the msvs/bin/release|debug directories.
## RedisWatcher
So far the RedisWatcher is not carried over to 2.6. However this should not be affected by the Redis version, and the code in the 2.4 branch should work with the Redis 2.6 binaries.
## RedisWAInst
So far the RedisWAInst is not carried over to 2.6. However this should not be affected by the Redis version, and the code in the 2.4 branch should work with the Redis 2.6 binaries.
## Release Notes
The branch has been renamed from 2.6_alpha to 2.6 to indicate that the test pass has been completed.
This is a release version of the software.
To run the Redis test suite requires some manual work:
- The tests assume that the binaries are in the src folder, so you need to copy the binaries from the msvs folder to src.
- 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. To execute the tests, run the following command: `tclsh8.5.exe tests/test_helper.tcl`.
If a Unix shell is not installed you may see the following error message: "couldn't execute "cat": no such file or directory".
## Known issues
None.

Following are change highlights associated with official releases. Important
bug fixes are all mentioned, but internal enhancements are omitted here for
brevity (even though they are more fun to write about). Much more detail can be
found in the git revision history:
http://www.canonware.com/cgi-bin/gitweb.cgi?p=jemalloc.git
git://canonware.com/jemalloc.git
* 3.0.0 (May 11, 2012)
Although this version adds some major new features, the primary focus is on
internal code cleanup that facilitates maintainability and portability, most
of which is not reflected in the ChangeLog. This is the first release to
incorporate substantial contributions from numerous other developers, and the
result is a more broadly useful allocator (see the git revision history for
contribution details). Note that the license has been unified, thanks to
Facebook granting a license under the same terms as the other copyright
holders (see COPYING).
New features:
- Implement Valgrind support, redzones, and quarantine.
- Add support for additional platforms:
+ FreeBSD
+ Mac OS X Lion
+ MinGW
+ Windows (no support yet for replacing the system malloc)
- Add support for additional architectures:
+ MIPS
+ SH4
+ Tilera
- Add support for cross compiling.
- Add nallocm(), which rounds a request size up to the nearest size class
without actually allocating.
- Implement aligned_alloc() (blame C11).
- Add the "thread.tcache.enabled" mallctl.
- Add the "opt.prof_final" mallctl.
- Update pprof (from gperftools 2.0).
- Add the --with-mangling option.
- Add the --disable-experimental option.
- Add the --disable-munmap option, and make it the default on Linux.
- Add the --enable-mremap option, which disables use of mremap(2) by default.
Incompatible changes:
- Enable stats by default.
- Enable fill by default.
- Disable lazy locking by default.
- Rename the "tcache.flush" mallctl to "thread.tcache.flush".
- Rename the "arenas.pagesize" mallctl to "arenas.page".
- Change the "opt.lg_prof_sample" default from 0 to 19 (1 B to 512 KiB).
- Change the "opt.prof_accum" default from true to false.
Removed features:
- Remove the swap feature, including the "config.swap", "swap.avail",
"swap.prezeroed", "swap.nfds", and "swap.fds" mallctls.
- Remove highruns statistics, including the
"stats.arenas.<i>.bins.<j>.highruns" and
"stats.arenas.<i>.lruns.<j>.highruns" mallctls.
- As part of small size class refactoring, remove the "opt.lg_[qc]space_max",
"arenas.cacheline", "arenas.subpage", "arenas.[tqcs]space_{min,max}", and
"arenas.[tqcs]bins" mallctls.
- Remove the "arenas.chunksize" mallctl.
- Remove the "opt.lg_prof_tcmax" option.
- Remove the "opt.lg_prof_bt_max" option.
- Remove the "opt.lg_tcache_gc_sweep" option.
- Remove the --disable-tiny option, including the "config.tiny" mallctl.
- Remove the --enable-dynamic-page-shift configure option.
- Remove the --enable-sysv configure option.
Bug fixes:
- Fix a statistics-related bug in the "thread.arena" mallctl that could cause
invalid statistics and crashes.
- Work around TLS deallocation via free() on Linux. This bug could cause
write-after-free memory corruption.
- Fix a potential deadlock that could occur during interval- and
growth-triggered heap profile dumps.
- Fix large calloc() zeroing bugs due to dropping chunk map unzeroed flags.
- Fix chunk_alloc_dss() to stop claiming memory is zeroed. This bug could
cause memory corruption and crashes with --enable-dss specified.
- Fix fork-related bugs that could cause deadlock in children between fork
and exec.
- Fix malloc_stats_print() to honor 'b' and 'l' in the opts parameter.
- Fix realloc(p, 0) to act like free(p).
- Do not enforce minimum alignment in memalign().
- Check for NULL pointer in malloc_usable_size().
- Fix an off-by-one heap profile statistics bug that could be observed in
interval- and growth-triggered heap profiles.
- Fix the "epoch" mallctl to update cached stats even if the passed in epoch
is 0.
- Fix bin->runcur management to fix a layout policy bug. This bug did not
affect correctness.
- Fix a bug in choose_arena_hard() that potentially caused more arenas to be
initialized than necessary.
- Add missing "opt.lg_tcache_max" mallctl implementation.
- Use glibc allocator hooks to make mixed allocator usage less likely.
- Fix build issues for --disable-tcache.
- Don't mangle pthread_create() when --with-private-namespace is specified.
* 2.2.5 (November 14, 2011)
Bug fixes:
- Fix huge_ralloc() race when using mremap(2). This is a serious bug that
could cause memory corruption and/or crashes.
- Fix huge_ralloc() to maintain chunk statistics.
- Fix malloc_stats_print(..., "a") output.
* 2.2.4 (November 5, 2011)
Bug fixes:
- Initialize arenas_tsd before using it. This bug existed for 2.2.[0-3], as
well as for --disable-tls builds in earlier releases.
- Do not assume a 4 KiB page size in test/rallocm.c.
* 2.2.3 (August 31, 2011)
This version fixes numerous bugs related to heap profiling.
Bug fixes:
- Fix a prof-related race condition. This bug could cause memory corruption,
but only occurred in non-default configurations (prof_accum:false).
- Fix off-by-one backtracing issues (make sure that prof_alloc_prep() is
excluded from backtraces).
- Fix a prof-related bug in realloc() (only triggered by OOM errors).
- Fix prof-related bugs in allocm() and rallocm().
- Fix prof_tdata_cleanup() for --disable-tls builds.
- Fix a relative include path, to fix objdir builds.
* 2.2.2 (July 30, 2011)
Bug fixes:
- Fix a build error for --disable-tcache.
- Fix assertions in arena_purge() (for real this time).
- Add the --with-private-namespace option. This is a workaround for symbol
conflicts that can inadvertently arise when using static libraries.
* 2.2.1 (March 30, 2011)
Bug fixes:
- Implement atomic operations for x86/x64. This fixes compilation failures
for versions of gcc that are still in wide use.
- Fix an assertion in arena_purge().
* 2.2.0 (March 22, 2011)
This version incorporates several improvements to algorithms and data
structures that tend to reduce fragmentation and increase speed.
New features:
- Add the "stats.cactive" mallctl.
- Update pprof (from google-perftools 1.7).
- Improve backtracing-related configuration logic, and add the
--disable-prof-libgcc option.
Bug fixes:
- Change default symbol visibility from "internal", to "hidden", which
decreases the overhead of library-internal function calls.
- Fix symbol visibility so that it is also set on OS X.
- Fix a build dependency regression caused by the introduction of the .pic.o
suffix for PIC object files.
- Add missing checks for mutex initialization failures.
- Don't use libgcc-based backtracing except on x64, where it is known to work.
- Fix deadlocks on OS X that were due to memory allocation in
pthread_mutex_lock().
- Heap profiling-specific fixes:
+ Fix memory corruption due to integer overflow in small region index
computation, when using a small enough sample interval that profiling
context pointers are stored in small run headers.
+ Fix a bootstrap ordering bug that only occurred with TLS disabled.
+ Fix a rallocm() rsize bug.
+ Fix error detection bugs for aligned memory allocation.
* 2.1.3 (March 14, 2011)
Bug fixes:
- Fix a cpp logic regression (due to the "thread.{de,}allocatedp" mallctl fix
for OS X in 2.1.2).
- Fix a "thread.arena" mallctl bug.
- Fix a thread cache stats merging bug.
* 2.1.2 (March 2, 2011)
Bug fixes:
- Fix "thread.{de,}allocatedp" mallctl for OS X.
- Add missing jemalloc.a to build system.
* 2.1.1 (January 31, 2011)
Bug fixes:
- Fix aligned huge reallocation (affected allocm()).
- Fix the ALLOCM_LG_ALIGN macro definition.
- Fix a heap dumping deadlock.
- Fix a "thread.arena" mallctl bug.
* 2.1.0 (December 3, 2010)
This version incorporates some optimizations that can't quite be considered
bug fixes.
New features:
- Use Linux's mremap(2) for huge object reallocation when possible.
- Avoid locking in mallctl*() when possible.
- Add the "thread.[de]allocatedp" mallctl's.
- Convert the manual page source from roff to DocBook, and generate both roff
and HTML manuals.
Bug fixes:
- Fix a crash due to incorrect bootstrap ordering. This only impacted
--enable-debug --enable-dss configurations.
- Fix a minor statistics bug for mallctl("swap.avail", ...).
* 2.0.1 (October 29, 2010)
Bug fixes:
- Fix a race condition in heap profiling that could cause undefined behavior
if "opt.prof_accum" were disabled.
- Add missing mutex unlocks for some OOM error paths in the heap profiling
code.
- Fix a compilation error for non-C99 builds.
* 2.0.0 (October 24, 2010)
This version focuses on the experimental *allocm() API, and on improved
run-time configuration/introspection. Nonetheless, numerous performance
improvements are also included.
New features:
- Implement the experimental {,r,s,d}allocm() API, which provides a superset
of the functionality available via malloc(), calloc(), posix_memalign(),
realloc(), malloc_usable_size(), and free(). These functions can be used to
allocate/reallocate aligned zeroed memory, ask for optional extra memory
during reallocation, prevent object movement during reallocation, etc.
- Replace JEMALLOC_OPTIONS/JEMALLOC_PROF_PREFIX with MALLOC_CONF, which is
more human-readable, and more flexible. For example:
JEMALLOC_OPTIONS=AJP
is now:
MALLOC_CONF=abort:true,fill:true,stats_print:true
- Port to Apple OS X. Sponsored by Mozilla.
- Make it possible for the application to control thread-->arena mappings via
the "thread.arena" mallctl.
- Add compile-time support for all TLS-related functionality via pthreads TSD.
This is mainly of interest for OS X, which does not support TLS, but has a
TSD implementation with similar performance.
- Override memalign() and valloc() if they are provided by the system.
- Add the "arenas.purge" mallctl, which can be used to synchronously purge all
dirty unused pages.
- Make cumulative heap profiling data optional, so that it is possible to
limit the amount of memory consumed by heap profiling data structures.
- Add per thread allocation counters that can be accessed via the
"thread.allocated" and "thread.deallocated" mallctls.
Incompatible changes:
- Remove JEMALLOC_OPTIONS and malloc_options (see MALLOC_CONF above).
- Increase default backtrace depth from 4 to 128 for heap profiling.
- Disable interval-based profile dumps by default.
Bug fixes:
- Remove bad assertions in fork handler functions. These assertions could
cause aborts for some combinations of configure settings.
- Fix strerror_r() usage to deal with non-standard semantics in GNU libc.
- Fix leak context reporting. This bug tended to cause the number of contexts
to be underreported (though the reported number of objects and bytes were
correct).
- Fix a realloc() bug for large in-place growing reallocation. This bug could
cause memory corruption, but it was hard to trigger.
- Fix an allocation bug for small allocations that could be triggered if
multiple threads raced to create a new run of backing pages.
- Enhance the heap profiler to trigger samples based on usable size, rather
than request size.
- Fix a heap profiling bug due to sometimes losing track of requested object
size for sampled objects.
* 1.0.3 (August 12, 2010)
Bug fixes:
- Fix the libunwind-based implementation of stack backtracing (used for heap
profiling). This bug could cause zero-length backtraces to be reported.
- Add a missing mutex unlock in library initialization code. If multiple
threads raced to initialize malloc, some of them could end up permanently
blocked.
* 1.0.2 (May 11, 2010)
Bug fixes:
- Fix junk filling of large objects, which could cause memory corruption.
- Add MAP_NORESERVE support for chunk mapping, because otherwise virtual
memory limits could cause swap file configuration to fail. Contributed by
Jordan DeLong.
* 1.0.1 (April 14, 2010)
Bug fixes:
- Fix compilation when --enable-fill is specified.
- Fix threads-related profiling bugs that affected accuracy and caused memory
to be leaked during thread exit.
- Fix dirty page purging race conditions that could cause crashes.
- Fix crash in tcache flushing code during thread destruction.
* 1.0.0 (April 11, 2010)
This release focuses on speed and run-time introspection. Numerous
algorithmic improvements make this release substantially faster than its
predecessors.
New features:
- Implement autoconf-based configuration system.
- Add mallctl*(), for the purposes of introspection and run-time
configuration.
- Make it possible for the application to manually flush a thread's cache, via
the "tcache.flush" mallctl.
- Base maximum dirty page count on proportion of active memory.
- Compute various addtional run-time statistics, including per size class
statistics for large objects.
- Expose malloc_stats_print(), which can be called repeatedly by the
application.
- Simplify the malloc_message() signature to only take one string argument,
and incorporate an opaque data pointer argument for use by the application
in combination with malloc_stats_print().
- Add support for allocation backed by one or more swap files, and allow the
application to disable over-commit if swap files are in use.
- Implement allocation profiling and leak checking.
Removed features:
- Remove the dynamic arena rebalancing code, since thread-specific caching
reduces its utility.
Bug fixes:
- Modify chunk allocation to work when address space layout randomization
(ASLR) is in use.
- Fix thread cleanup bugs related to TLS destruction.
- Handle 0-size allocation requests in posix_memalign().
- Fix a chunk leak. The leaked chunks were never touched, so this impacted
virtual memory usage, but not physical memory usage.
* linux_2008082[78]a (August 27/28, 2008)
These snapshot releases are the simple result of incorporating Linux-specific
support into the FreeBSD malloc sources.

Building and installing jemalloc can be as simple as typing the following while
in the root directory of the source tree:
./configure
make
make install
=== Advanced configuration =====================================================
The 'configure' script supports numerous options that allow control of which
functionality is enabled, where jemalloc is installed, etc. Optionally, pass
any of the following arguments (not a definitive list) to 'configure':
--help
Print a definitive list of options.
--prefix=<install-root-dir>
Set the base directory in which to install. For example:
./configure --prefix=/usr/local
will cause files to be installed into /usr/local/include, /usr/local/lib,
and /usr/local/man.
--with-rpath=<colon-separated-rpath>
Embed one or more library paths, so that libjemalloc can find the libraries
it is linked to. This works only on ELF-based systems.
--with-mangling=<map>
Mangle public symbols specified in <map> which is a comma-separated list of
name:mangled pairs.
For example, to use ld's --wrap option as an alternative method for
overriding libc's malloc implementation, specify something like:
--with-mangling=malloc:__wrap_malloc,free:__wrap_free[...]
Note that mangling happens prior to application of the prefix specified by
--with-jemalloc-prefix, and mangled symbols are then ignored when applying
the prefix.
--with-jemalloc-prefix=<prefix>
Prefix all public APIs with <prefix>. For example, if <prefix> is
"prefix_", API changes like the following occur:
malloc() --> prefix_malloc()
malloc_conf --> prefix_malloc_conf
/etc/malloc.conf --> /etc/prefix_malloc.conf
MALLOC_CONF --> PREFIX_MALLOC_CONF
This makes it possible to use jemalloc at the same time as the system
allocator, or even to use multiple copies of jemalloc simultaneously.
By default, the prefix is "", except on OS X, where it is "je_". On OS X,
jemalloc overlays the default malloc zone, but makes no attempt to actually
replace the "malloc", "calloc", etc. symbols.
--with-private-namespace=<prefix>
Prefix all library-private APIs with <prefix>. For shared libraries,
symbol visibility mechanisms prevent these symbols from being exported, but
for static libraries, naming collisions are a real possibility. By
default, the prefix is "" (empty string).
--with-install-suffix=<suffix>
Append <suffix> to the base name of all installed files, such that multiple
versions of jemalloc can coexist in the same installation directory. For
example, libjemalloc.so.0 becomes libjemalloc<suffix>.so.0.
--enable-cc-silence
Enable code that silences non-useful compiler warnings. This is helpful
when trying to tell serious warnings from those due to compiler
limitations, but it potentially incurs a performance penalty.
--enable-debug
Enable assertions and validation code. This incurs a substantial
performance hit, but is very useful during application development.
--disable-stats
Disable statistics gathering functionality. See the "opt.stats_print"
option documentation for usage details.
--enable-prof
Enable heap profiling and leak detection functionality. See the "opt.prof"
option documentation for usage details. When enabled, there are several
approaches to backtracing, and the configure script chooses the first one
in the following list that appears to function correctly:
+ libunwind (requires --enable-prof-libunwind)
+ libgcc (unless --disable-prof-libgcc)
+ gcc intrinsics (unless --disable-prof-gcc)
--enable-prof-libunwind
Use the libunwind library (http://www.nongnu.org/libunwind/) for stack
backtracing.
--disable-prof-libgcc
Disable the use of libgcc's backtracing functionality.
--disable-prof-gcc
Disable the use of gcc intrinsics for backtracing.
--with-static-libunwind=<libunwind.a>
Statically link against the specified libunwind.a rather than dynamically
linking with -lunwind.
--disable-tcache
Disable thread-specific caches for small objects. Objects are cached and
released in bulk, thus reducing the total number of mutex operations. See
the "opt.tcache" option for usage details.
--enable-mremap
Enable huge realloc() via mremap(2). mremap() is disabled by default
because the flavor used is specific to Linux, which has a quirk in its
virtual memory allocation algorithm that causes semi-permanent VM map holes
under normal jemalloc operation.
--disable-munmap
Disable virtual memory deallocation via munmap(2); instead keep track of
the virtual memory for later use. munmap() is disabled by default (i.e.
--disable-munmap is implied) on Linux, which has a quirk in its virtual
memory allocation algorithm that causes semi-permanent VM map holes under
normal jemalloc operation.
--enable-dss
Enable support for page allocation/deallocation via sbrk(2), in addition to
mmap(2).
--disable-fill
Disable support for junk/zero filling of memory, quarantine, and redzones.
See the "opt.junk", "opt.zero", "opt.quarantine", and "opt.redzone" option
documentation for usage details.
--disable-valgrind
Disable support for Valgrind.
--disable-experimental
Disable support for the experimental API (*allocm()).
--enable-utrace
Enable utrace(2)-based allocation tracing. This feature is not broadly
portable (FreeBSD has it, but Linux and OS X do not).
--enable-xmalloc
Enable support for optional immediate termination due to out-of-memory
errors, as is commonly implemented by "xmalloc" wrapper function for malloc.
See the "opt.xmalloc" option documentation for usage details.
--enable-lazy-lock
Enable code that wraps pthread_create() to detect when an application
switches from single-threaded to multi-threaded mode, so that it can avoid
mutex locking/unlocking operations while in single-threaded mode. In
practice, this feature usually has little impact on performance unless
thread-specific caching is disabled.
--disable-tls
Disable thread-local storage (TLS), which allows for fast access to
thread-local variables via the __thread keyword. If TLS is available,
jemalloc uses it for several purposes.
--with-xslroot=<path>
Specify where to find DocBook XSL stylesheets when building the
documentation.
The following environment variables (not a definitive list) impact configure's
behavior:
CFLAGS="?"
Pass these flags to the compiler. You probably shouldn't define this unless
you know what you are doing. (Use EXTRA_CFLAGS instead.)
EXTRA_CFLAGS="?"
Append these flags to CFLAGS. This makes it possible to add flags such as
-Werror, while allowing the configure script to determine what other flags
are appropriate for the specified configuration.
The configure script specifically checks whether an optimization flag (-O*)
is specified in EXTRA_CFLAGS, and refrains from specifying an optimization
level if it finds that one has already been specified.
CPPFLAGS="?"
Pass these flags to the C preprocessor. Note that CFLAGS is not passed to
'cpp' when 'configure' is looking for include files, so you must use
CPPFLAGS instead if you need to help 'configure' find header files.
LD_LIBRARY_PATH="?"
'ld' uses this colon-separated list to find libraries.
LDFLAGS="?"
Pass these flags when linking.
PATH="?"
'configure' uses this to find programs.
=== Advanced compilation =======================================================
To build only parts of jemalloc, use the following targets:
build_lib_shared
build_lib_static
build_lib
build_doc_html
build_doc_man
build_doc
To install only parts of jemalloc, use the following targets:
install_bin
install_include
install_lib_shared
install_lib_static
install_lib
install_doc_html
install_doc_man
install_doc
To clean up build results to varying degrees, use the following make targets:
clean
distclean
relclean
=== Advanced installation ======================================================
Optionally, define make variables when invoking make, including (not
exclusively):
INCLUDEDIR="?"
Use this as the installation prefix for header files.
LIBDIR="?"
Use this as the installation prefix for libraries.
MANDIR="?"
Use this as the installation prefix for man pages.
DESTDIR="?"
Prepend DESTDIR to INCLUDEDIR, LIBDIR, DATADIR, and MANDIR. This is useful
when installing to a different path than was specified via --prefix.
CC="?"
Use this to invoke the C compiler.
CFLAGS="?"
Pass these flags to the compiler.
CPPFLAGS="?"
Pass these flags to the C preprocessor.
LDFLAGS="?"
Pass these flags when linking.
PATH="?"
Use this to search for programs used during configuration and building.
=== Development ================================================================
If you intend to make non-trivial changes to jemalloc, use the 'autogen.sh'
script rather than 'configure'. This re-generates 'configure', enables
configuration dependency rules, and enables re-generation of automatically
generated source files.
The build system supports using an object directory separate from the source
tree. For example, you can create an 'obj' directory, and from within that
directory, issue configuration and build commands:
autoconf
mkdir obj
cd obj
../configure --enable-autogen
make
=== Documentation ==============================================================
The manual page is generated in both html and roff formats. Any web browser
can be used to view the html manual. The roff manual page can be formatted
prior to installation via the following command:
nroff -man -t doc/jemalloc.3
deps/jemalloc/Makefile.in

jemalloc is a general-purpose scalable concurrent malloc(3) implementation.
This distribution is a "portable" implementation that currently targets
FreeBSD, Linux, Apple OS X, and MinGW. jemalloc is included as the default
allocator in the FreeBSD and NetBSD operating systems, and it is used by the
Mozilla Firefox web browser on Microsoft Windows-related platforms. Depending
on your needs, one of the other divergent versions may suit your needs better
than this distribution.
The COPYING file contains copyright and licensing information.
The INSTALL file contains information on how to configure, build, and install
jemalloc.
The ChangeLog file contains a brief summary of changes for each release.

/*
* The rb_gen() macro generates a type-specific red-black tree implementation,
* based on the above cpp macros.
*
* Arguments:
*
* a_attr : Function attribute for generated functions (ex: static).
* a_prefix : Prefix for generated functions (ex: ex_).
* a_rb_type : Type for red-black tree data structure (ex: ex_t).
* a_type : Type for red-black tree node data structure (ex: ex_node_t).
* a_field : Name of red-black tree node linkage (ex: ex_link).
* a_cmp : Node comparison function name, with the following prototype:
* int (a_cmp *)(a_type *a_node, a_type *a_other);
* ^^^^^^
* or a_key
* Interpretation of comparision function return values:
* -1 : a_node < a_other
* 0 : a_node == a_other
* 1 : a_node > a_other
* In all cases, the a_node or a_key macro argument is the first
* argument to the comparison function, which makes it possible
* to write comparison functions that treat the first argument
* specially.
*
* Assuming the following setup:
*
* typedef struct ex_node_s ex_node_t;
* struct ex_node_s {
* rb_node(ex_node_t) ex_link;
* };
* typedef rb_tree(ex_node_t) ex_t;
* rb_gen(static, ex_, ex_t, ex_node_t, ex_link, ex_cmp)
*
* The following API is generated:
*
* static void
* ex_new(ex_t *tree);
* Description: Initialize a red-black tree structure.
* Args:
* tree: Pointer to an uninitialized red-black tree object.
*
* static ex_node_t *
* ex_first(ex_t *tree);
* static ex_node_t *
* ex_last(ex_t *tree);
* Description: Get the first/last node in tree.
* Args:
* tree: Pointer to an initialized red-black tree object.
* Ret: First/last node in tree, or NULL if tree is empty.
*
* static ex_node_t *
* ex_next(ex_t *tree, ex_node_t *node);
* static ex_node_t *
* ex_prev(ex_t *tree, ex_node_t *node);
* Description: Get node's successor/predecessor.
* Args:
* tree: Pointer to an initialized red-black tree object.
* node: A node in tree.
* Ret: node's successor/predecessor in tree, or NULL if node is
* last/first.
*
* static ex_node_t *
* ex_search(ex_t *tree, ex_node_t *key);
* Description: Search for node that matches key.
* Args:
* tree: Pointer to an initialized red-black tree object.
* key : Search key.
* Ret: Node in tree that matches key, or NULL if no match.
*
* static ex_node_t *
* ex_nsearch(ex_t *tree, ex_node_t *key);
* static ex_node_t *
* ex_psearch(ex_t *tree, ex_node_t *key);
* Description: Search for node that matches key. If no match is found,
* return what would be key's successor/predecessor, were
* key in tree.
* Args:
* tree: Pointer to an initialized red-black tree object.
* key : Search key.
* Ret: Node in tree that matches key, or if no match, hypothetical node's
* successor/predecessor (NULL if no successor/predecessor).
*
* static void
* ex_insert(ex_t *tree, ex_node_t *node);
* Description: Insert node into tree.
* Args:
* tree: Pointer to an initialized red-black tree object.
* node: Node to be inserted into tree.
*
* static void
* ex_remove(ex_t *tree, ex_node_t *node);
* Description: Remove node from tree.
* Args:
* tree: Pointer to an initialized red-black tree object.
* node: Node in tree to be removed.
*
* static ex_node_t *
* ex_iter(ex_t *tree, ex_node_t *start, ex_node_t *(*cb)(ex_t *,
* ex_node_t *, void *), void *arg);
* static ex_node_t *
* ex_reverse_iter(ex_t *tree, ex_node_t *start, ex_node *(*cb)(ex_t *,
* ex_node_t *, void *), void *arg);
* Description: Iterate forward/backward over tree, starting at node. If
* tree is modified, iteration must be immediately
* terminated by the callback function that causes the
* modification.
* Args:
* tree : Pointer to an initialized red-black tree object.
* start: Node at which to start iteration, or NULL to start at
* first/last node.
* cb : Callback function, which is called for each node during
* iteration. Under normal circumstances the callback function
* should return NULL, which causes iteration to continue. If a
* callback function returns non-NULL, iteration is immediately
* terminated and the non-NULL return value is returned by the
* iterator. This is useful for re-starting iteration after
* modifying tree.
* arg : Opaque pointer passed to cb().
* Ret: NULL if iteration completed, or the non-NULL callback return value
* that caused termination of the iteration.

/*
* TLS/TSD-agnostic macro-based implementation of thread-specific data. There
* are four macros that support (at least) three use cases: file-private,
* library-private, and library-private inlined. Following is an example
* library-private tsd variable:
*
* In example.h:
* typedef struct {
* int x;
* int y;
* } example_t;
* #define EX_INITIALIZER JEMALLOC_CONCAT({0, 0})
* malloc_tsd_protos(, example, example_t *)
* malloc_tsd_externs(example, example_t *)
* In example.c:
* malloc_tsd_data(, example, example_t *, EX_INITIALIZER)
* malloc_tsd_funcs(, example, example_t *, EX_INITIALIZER,
* example_tsd_cleanup)
*
* The result is a set of generated functions, e.g.:
*
* bool example_tsd_boot(void) {...}
* example_t **example_tsd_get() {...}
* void example_tsd_set(example_t **val) {...}
*
* Note that all of the functions deal in terms of (a_type *) rather than
* (a_type) so that it is possible to support non-pointer types (unlike
* pthreads TSD). example_tsd_cleanup() is passed an (a_type *) pointer that is
* cast to (void *). This means that the cleanup function needs to cast *and*
* dereference the function argument, e.g.:
*
* void
* example_tsd_cleanup(void *arg)
* {
* example_t *example = *(example_t **)arg;
*
* [...]
* if ([want the cleanup function to be called again]) {
* example_tsd_set(&example);
* }
* }
*
* If example_tsd_set() is called within example_tsd_cleanup(), it will be
* called again. This is similar to how pthreads TSD destruction works, except
* that pthreads only calls the cleanup function again if the value was set to
* non-NULL.

*******************************************************************************
* Implementation of (2^1+,2) cuckoo hashing, where 2^1+ indicates that each
* hash bucket contains 2^n cells, for n >= 1, and 2 indicates that two hash
* functions are employed. The original cuckoo hashing algorithm was described
* in:
*
* Pagh, R., F.F. Rodler (2004) Cuckoo Hashing. Journal of Algorithms
* 51(2):122-144.
*
* Generalization of cuckoo hashing was discussed in:
*
* Erlingsson, U., M. Manasse, F. McSherry (2006) A cool and practical
* alternative to traditional hash tables. In Proceedings of the 7th
* Workshop on Distributed Data and Structures (WDAS'06), Santa Clara, CA,
* January 2006.
*
* This implementation uses precisely two hash functions because that is the
* fewest that can work, and supporting multiple hashes is an implementation
* burden. Here is a reproduction of Figure 1 from Erlingsson et al. (2006)
* that shows approximate expected maximum load factors for various
* configurations:
*
* | #cells/bucket |
* #hashes | 1 | 2 | 4 | 8 |
* --------+-------+-------+-------+-------+
* 1 | 0.006 | 0.006 | 0.03 | 0.12 |
* 2 | 0.49 | 0.86 |>0.93< |>0.96< |
* 3 | 0.91 | 0.97 | 0.98 | 0.999 |
* 4 | 0.97 | 0.99 | 0.999 | |
*
* The number of cells per bucket is chosen such that a bucket fits in one cache
* line. So, on 32- and 64-bit systems, we use (8,2) and (4,2) cuckoo hashing,
* respectively.
