+Redis 2.6 release notes
+=======================
 
-There is no release notes for this branch, it gets forked into another branch
-every time there is a partial feature freeze in order to eventually create
-a new stable release.
+** IMPORTANT ** Check the 'Migrating from 2.4 to 2.6' section at the end of
+                this file for information about what changed between 2.4 and
+                2.6 and how this may affect your application.
 
-Usually "unstable" is stable enough for you to use it in development environments
-however you should never use it in production environments. It is possible
-to download the latest stable release here:
+--------------------------------------------------------------------------------
+Upgrade urgency levels:
 
-    https://download.redis.io/redis-stable.tar.gz
+LOW:      No need to upgrade unless there are new features you want to use.
+MODERATE: Program an upgrade of the server, but it's not urgent.
+HIGH:     There is a critical bug that may affect a subset of users. Upgrade!
+CRITICAL: There is a critical bug affecting MOST USERS. Upgrade ASAP.

+UPGRADE URGENCY: HIGH
+
+* [BUGFIX]   Theoretical bug in ziplist fixed.
+* [BUGFIX]   Better out of memory handling (Log produced in log file).
+* [BUGFIX]   Incrementally flush RDB file on slave side while performing the
+             first synchronization with the master. This makes Redis less
+             blocking in environments where disk I/O is slow.
+* [BUGFIX]   Don't crash with Lua's redis.call() without arguments.
+* [BUGFIX]   Don't crash after a big number of Lua calls on 32 bit systems
+             because of a failed assertion.
+* [BUGFIX]   Fix SORT behaviour when called from scripting.
+* [BUGFIX]   Adjust slave PING period accordingly to REDIS_HZ define.
+* [BUGFIX]   BITCOUNT: fix crash on overflowing arguments.
+* [BUGFIX]   Return an error when SELECT argument is not an integer.
+* [BUGFIX]   Blocking operations on lists were completely reimplemented for
+             correctness. Now blocking list ops and pushes originated from
+             Lua scripts will play well together and will be replicated
+             and transmitted to the AOF correctly.
+* [IMPROVED] Send async PING before starting replication to avoid blocking if
+             master allows us to connect but it is actually not able to reply.
+* [IMPROVED] Support slave-priority for Redis Sentinel.
+* [IMPROVED] Hiredis library updated.
+
+---[ Redis 2.5.12 (2.6 Release Candidate 6) ]
+
+UPGRADE URGENCY: MODERATE.
+
+* [BUGFIX]   Fixed a timing attack on AUTH (Issue #560).
+* [BUGFIX]   Don't assume that "char" is signed.
+* [BUGFIX]   Check that we have connection before enabling pipe mode.
+* [BUGFIX]   Use the optimized version of the function to convert a double to
+             its string representation. Compilation was disabled because of
+             a typo in the #if statement.
+* [IMPROVED} REPLCONF internal command introduced, now INFO shows slaves with
+             correct port numbers. This makes 2.5.12 Redis Sentinel compatible.
+* [IMPROVED] Truncate short write from the AOF for a cleaner restart. On short
+             writes (for instance out of space) Redis will now try to remove
+             the half-written data so that the next restart will work without
+             the need for the "redis-check-aof" utility.
+* [IMPROVED] New in INFO: aof_last_bgrewrite_status
+* [IMPROVED] Allow Pub/Sub in contexts where other commands are blocked.
+* [BUGFIX]   mark fd as writable when EPOLLERR or EPOLLHUP is returned by
+             epoll_wait.
+
+---[ Redis 2.5.11 (2.6 Release Candidate 5) ]
+
+UPGRADE URGENCY: HIGH.
+
+* [BUGFIX]   Fixed Hash corruption when loading an RDB file generated by
+             previous versions of Redis that encoded hashes using
+             a different ziplist encoding format for small integers.
+             All the fileds that are integers in the range 0-255 may not
+             be recognized, or duplicated un updates, causing a crash
+             when the ziplist is converted to a real hash. (Issue #547).
+* [BUGFIX]   Fixed the count of memory used by output buffers in the
+             setDeferredMultiBulkLength() function.
+
+---[ Redis 2.5.10 (2.6 Release Candidate 4) ]
+
+UPGRADE URGENCY: HIGH.
+
+* [BUGFIX]   Allow PREFIX to be overwritten on "make install".
+* [BUGFIX]   Run the test with just one client if the computer is slow.
+* [BUGFIX]   Event port support in our event driven libray.
+* [BUGFIX]   Jemalloc updated to 3.0.0. This fixes a possibly AOF rewrite issue.
+             See https://github.com/antirez/redis/issues/504 for info.
+* [BUGFIX]   Fixed issue #516: ZINTERSTORE / ZUNIONSTORE with mixed sets/zsets.
+* [BUGFIX]   Set fd to writable when poll(2) detects POLLERR or POLLHUP event.
+* [BUGFIX]   Fixed RESTORE hash failure (Issue #532).
+* [IMPROVED] Allow an AOF rewrite buffer > 2GB (Related to issue #504).
+* [IMPROVED] Server cron function frequency is now configurable (REDIS_HZ).
+* [IMPROVED] Better, less blocking expired keys collection algorithm.
+* [FEATURE]  New commands: BITOP and BITCOUNT.
+* [FEATURE]  redis-cli --pipe for mass import.
+
+What's new in Redis 2.5.9 (aka 2.6 Release Candidate 3)
+=======================================================
+
+UPGRADE URGENCY: critical, upgrade ASAP.
+
+* [BUGFIX] Fix for issue #500 (https://github.com/antirez/redis/pull/500).
+           Redis 2.6-RC1 and RC2 may corrupt ziplist-encoded sorted sets
+           produced by Redis 2.4.x.
+* [BUGFIX] Fixed several bugs in init.d script.
+* [BUGFIX] syncio.c functions modified for speed and correctness. On osx
+           (and possibly other BSD-based systems) the slave would block on
+           replication to send the SYNC command when the master was not
+           available. This is fixed now, but was not affecting Linux installs.
+* Now when slave-serve-stale-data is set to yes and the master is down, instead
+  of reporting a generic error Redis replies with -MASTERDOWN.
+
+What's new in Redis 2.5.8 (aka 2.6 Release Candidate 2)
+=======================================================
+
+UPGRADE URGENCY: high for all the users of the KEYS command, otherwise low.
+
+* [BUGFIX] Fix for KEYS command: if the DB contains keys with expires the KEYS
+           command may return the wrong output, having duplicated or missing
+           keys. See issue #487 and #488 on github for details.
+
+What's new in Redis 2.5.7 (aka 2.6 Release Candidate 1)
+=======================================================
+
+UPGRADE URGENCY: upgrade not recommended because this is an RC release.
+
+* This is the first release candidate for Redis 2.6. We are not aware of
+  bugs, but part of this code is young and was never tested in production
+  environments, so handle with care.
+
+An overview of new features and changes in Redis 2.6.x
+======================================================
+
+* Server side Lua scripting, see http://redis.io/commands/eval
+* Virtual Memory removed (was deprecated in 2.4)
+* Hardcoded limits about max number of clients removed.
+* AOF low level semantics is generally more sane, and especially when used
+  in slaves.
+* Milliseconds resolution expires, also added new commands with milliseconds
+  precision (PEXPIRE, PTTL, ...).
+* Better memory usage for "small" lists, ziplists and hashes when fields or
+  values contain small integers.
+* Read only slaves.
+* New bit opeations: BITCOUNT and BITOP commands.
+* Clients max output buffer soft and hard limits. You can specifiy different
+  limits for different classes of clients (normal,pubsub,slave).
+* More incremental (less blocking) expired keys collection algorithm, in
+  practical terms this means that Redis is more responsive when a very
+  big number of keys expire about at the same time.
+* AOF is now able to rewrite aggregate data types using variadic commands,
+  often producing an AOF that is faster to save, load, and is smaller in size.
+* Every redis.conf directive is now accepted as a command line option for the
+  redis-server binary, with the same name and number of arguments.
+* Hash table seed randomization for protection against collisions attacks.
+* Performances improved when writing large objects to Redis.
+* Integrated memory test, see redis-server --test-memory.
+* INCRBYFLOAT and HINCRBYFLOAT commands.
+* New DUMP, RESTORE, MIGRATE commands (back ported from Redis Cluster to 2.6).
+* CRC64 checksump in RDB files.
+* Better MONITOR output and behavior (now commands are logged before execution).
+* "Software Watchdog" feature to debug latency issues.
+* Significant parts of the core refactored or rewritten. New internal APIs
+  and core changes allowed to develop Redis Cluster on top of the new code,
+  however for 2.6 all the cluster code was removed, and will be released with
+  Redis 3.0 when it is more complete and stable.
+* Redis ASCII art logo added at startup.
+* Crash report on memory violation or failed asserts improved significantly
+  to make debugging of hard to catch bugs simpler.
+* redis-benchmark improvements: ability to run selected tests,
+  CSV output, faster, better help.
+* redis-cli improvements: --eval for comfortable development of Lua scripts.
+* SHUTDOWN now supports two optional arguments: "SAVE" and "NOSAVE".
+* INFO output split into sections, the command is now able to just show 
+  pecific sections.
+* New statistics about how many time a command was called, and how much
+  execution time it used (INFO commandstats).
+* More predictable SORT behavior in edge cases.
+* Better support for big endian and *BSD systems.
+* Build system improved.
+
+Migrating from 2.4 to 2.6
+=========================
+
+Redis 2.4 is mostly a strict subset of 2.6. However there are a few things
+that you should be aware of:
+
+* You can't use .rdb and AOF files generated with 2.6 into a 2.4 instance.
+* 2.6 slaves can be attached to 2.4 masters, but not the contrary, and only
+  for the time needed to perform the version upgrade.
+
+There are also a few API differences, that are unlikely to cause problems,
+but it is better to keep them in mind:
+
+* SORT now will refuse to sort in numerical mode elements that can't be parsed
+  as numbers.
+* EXPIREs now all have millisecond resolution (but this is very unlikely to
+  break code that was not conceived exploting the previous resolution error
+  in some way.)
+* INFO output is a bit different now, and contains empty lines and comments
+  starting with '#'. All the major clients should be already fixed to work
+  with the new INFO format.
+* Slaves are only read-only by default (but you can change this easily
+  setting the "slave-read-only" configuration option to "no" editing your
+  redis.conf or using CONFIG SET.
+
+The following INFO fields were renamed for consistency:
+
+     changes_since_last_save -> rdb_changes_since_last_save
+     bgsave_in_progress -> rdb_bgsave_in_progress
+     last_save_time -> rdb_last_save_time
+     last_bgsave_status -> rdb_last_bgsave_status
+     bgrewriteaof_in_progress -> aof_rewrite_in_progress
+     bgrewriteaof_scheduled -> aof_rewrite_scheduled
+
+The following redis.conf and CONFIG GET / SET parameters changed:
+
+    * hash-max-zipmap-entries, now replaced by hash-max-ziplist-entries
+    * hash-max-zipmap-value, now replaced by hash-max-ziplist-value
+    * glueoutputbuf option was now completely removed (was deprecated)

-# IMPORTANT: HOW TO USE REDIS GITHUB ISSUES
-
-GitHub issues SHOULD ONLY BE USED to report bugs and for DETAILED feature
-requests. Everything else should be asked on Discord:
-      
-    https://discord.com/invite/redis
-
-PLEASE DO NOT POST GENERAL QUESTIONS that are not about bugs or suspected
-bugs in the GitHub issues system. We'll be delighted to help you and provide
-all the support on Discord.
-
-There is also an active community of Redis users at Stack Overflow:
-
-    https://stackoverflow.com/questions/tagged/redis
-
-Issues and pull requests for documentation belong on the redis-doc repo:
-
-    https://github.com/redis/redis-doc
-
-If you are reporting a security bug or vulnerability, see SECURITY.md.
-
-# How to provide a patch for a new feature
-
-1. If it is a major feature or a semantical change, please don't start coding
-straight away: if your feature is not a conceptual fit you'll lose a lot of
-time writing the code without any reason. Start by posting in the mailing list
-and creating an issue at Github with the description of, exactly, what you want
-to accomplish and why. Use cases are important for features to be accepted.
-Here you can see if there is consensus about your idea.
-
-2. If in step 1 you get an acknowledgment from the project leaders, use the
-   following procedure to submit a patch:
-
-    a. Fork Redis on GitHub ( https://docs.github.com/en/github/getting-started-with-github/fork-a-repo )
-    b. Create a topic branch (git checkout -b my_branch)
-    c. Push to your branch (git push origin my_branch)
-    d. Initiate a pull request on GitHub ( https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request )
-    e. Done :)
-
-3. Keep in mind that we are very overloaded, so issues and PRs sometimes wait
-for a *very* long time. However this is not a lack of interest, as the project
-gets more and more users, we find ourselves in a constant need to prioritize
-certain issues/PRs over others. If you think your issue/PR is very important
-try to popularize it, have other users commenting and sharing their point of
-view, and so forth. This helps.
-
-4. For minor fixes - open a pull request on GitHub.
-
-Additional information on the RSALv2/SSPLv1 dual-license is also found in the LICENSE.txt file.

-2. Server Side Public License (SSPL)
-====================================
-
-                     Server Side Public License
-                     VERSION 1, OCTOBER 16, 2018
-
-                    Copyright (c) 2018 MongoDB, Inc.
-
-  Everyone is permitted to copy and distribute verbatim copies of this
-  license document, but changing it is not allowed.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to Server Side Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-  works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-  License.  Each licensee is addressed as "you". "Licensees" and
-  "recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work in
-  a fashion requiring copyright permission, other than the making of an
-  exact copy. The resulting work is called a "modified version" of the
-  earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based on
-  the Program.
-
-  To "propagate" a work means to do anything with it that, without
-  permission, would make you directly or secondarily liable for
-  infringement under applicable copyright law, except executing it on a
-  computer or modifying a private copy. Propagation includes copying,
-  distribution (with or without modification), making available to the
-  public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-  parties to make or receive copies. Mere interaction with a user through a
-  computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices" to the
-  extent that it includes a convenient and prominently visible feature that
-  (1) displays an appropriate copyright notice, and (2) tells the user that
-  there is no warranty for the work (except to the extent that warranties
-  are provided), that licensees may convey the work under this License, and
-  how to view a copy of this License. If the interface presents a list of
-  user commands or options, such as a menu, a prominent item in the list
-  meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work for
-  making modifications to it. "Object code" means any non-source form of a
-  work.
-
-  A "Standard Interface" means an interface that either is an official
-  standard defined by a recognized standards body, or, in the case of
-  interfaces specified for a particular programming language, one that is
-  widely used among developers working in that language.  The "System
-  Libraries" of an executable work include anything, other than the work as
-  a whole, that (a) is included in the normal form of packaging a Major
-  Component, but which is not part of that Major Component, and (b) serves
-  only to enable use of the work with that Major Component, or to implement
-  a Standard Interface for which an implementation is available to the
-  public in source code form. A "Major Component", in this context, means a
-  major essential component (kernel, window system, and so on) of the
-  specific operating system (if any) on which the executable work runs, or
-  a compiler used to produce the work, or an object code interpreter used
-  to run it.
-
-  The "Corresponding Source" for a work in object code form means all the
-  source code needed to generate, install, and (for an executable work) run
-  the object code and to modify the work, including scripts to control
-  those activities. However, it does not include the work's System
-  Libraries, or general-purpose tools or generally available free programs
-  which are used unmodified in performing those activities but which are
-  not part of the work. For example, Corresponding Source includes
-  interface definition files associated with source files for the work, and
-  the source code for shared libraries and dynamically linked subprograms
-  that the work is specifically designed to require, such as by intimate
-  data communication or control flow between those subprograms and other
-  parts of the work.
-
-  The Corresponding Source need not include anything that users can
-  regenerate automatically from other parts of the Corresponding Source.
-
-  The Corresponding Source for a work in source code form is that same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-  copyright on the Program, and are irrevocable provided the stated
-  conditions are met. This License explicitly affirms your unlimited
-  permission to run the unmodified Program, subject to section 13. The
-  output from running a covered work is covered by this License only if the
-  output, given its content, constitutes a covered work. This License
-  acknowledges your rights of fair use or other equivalent, as provided by
-  copyright law.  Subject to section 13, you may make, run and propagate
-  covered works that you do not convey, without conditions so long as your
-  license otherwise remains in force. You may convey covered works to
-  others for the sole purpose of having them make modifications exclusively
-  for you, or provide you with facilities for running those works, provided
-  that you comply with the terms of this License in conveying all
-  material for which you do not control copyright. Those thus making or
-  running the covered works for you must do so exclusively on your
-  behalf, under your direction and control, on terms that prohibit them
-  from making any copies of your copyrighted material outside their
-  relationship with you.
-
-  Conveying under any other circumstances is permitted solely under the
-  conditions stated below. Sublicensing is not allowed; section 10 makes it
-  unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-  measure under any applicable law fulfilling obligations under article 11
-  of the WIPO copyright treaty adopted on 20 December 1996, or similar laws
-  prohibiting or restricting circumvention of such measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-  circumvention of technological measures to the extent such circumvention is
-  effected by exercising rights under this License with respect to the
-  covered work, and you disclaim any intention to limit operation or
-  modification of the work as a means of enforcing, against the work's users,
-  your or third parties' legal rights to forbid circumvention of
-  technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-  receive it, in any medium, provided that you conspicuously and
-  appropriately publish on each copy an appropriate copyright notice; keep
-  intact all notices stating that this License and any non-permissive terms
-  added in accord with section 7 apply to the code; keep intact all notices
-  of the absence of any warranty; and give all recipients a copy of this
-  License along with the Program.  You may charge any price or no price for
-  each copy that you convey, and you may offer support or warranty
-  protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-  produce it from the Program, in the form of source code under the terms
-  of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified it,
-    and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is released
-    under this License and any conditions added under section 7. This
-    requirement modifies the requirement in section 4 to "keep intact all
-    notices".
-
-    c) You must license the entire work, as a whole, under this License to
-    anyone who comes into possession of a copy. This License will therefore
-    apply, along with any applicable section 7 additional terms, to the
-    whole of the work, and all its parts, regardless of how they are
-    packaged. This License gives no permission to license the work in any
-    other way, but it does not invalidate such permission if you have
-    separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your work
-    need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-  works, which are not by their nature extensions of the covered work, and
-  which are not combined with it such as to form a larger program, in or on
-  a volume of a storage or distribution medium, is called an "aggregate" if
-  the compilation and its resulting copyright are not used to limit the
-  access or legal rights of the compilation's users beyond what the
-  individual works permit. Inclusion of a covered work in an aggregate does
-  not cause this License to apply to the other parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms of
-  sections 4 and 5, provided that you also convey the machine-readable
-  Corresponding Source under the terms of this License, in one of these
-  ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium customarily
-    used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a written
-    offer, valid for at least three years and valid for as long as you
-    offer spare parts or customer support for that product model, to give
-    anyone who possesses the object code either (1) a copy of the
-    Corresponding Source for all the software in the product that is
-    covered by this License, on a durable physical medium customarily used
-    for software interchange, for a price no more than your reasonable cost
-    of physically performing this conveying of source, or (2) access to
-    copy the Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source. This alternative is
-    allowed only occasionally and noncommercially, and only if you received
-    the object code with such an offer, in accord with subsection 6b.
-
-    d) Convey the object code by offering access from a designated place
-    (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge. You need not require recipients to copy the
-    Corresponding Source along with the object code. If the place to copy
-    the object code is a network server, the Corresponding Source may be on
-    a different server (operated by you or a third party) that supports
-    equivalent copying facilities, provided you maintain clear directions
-    next to the object code saying where to find the Corresponding Source.
-    Regardless of what server hosts the Corresponding Source, you remain
-    obligated to ensure that it is available for as long as needed to
-    satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided you
-    inform other peers where the object code and Corresponding Source of
-    the work are being offered to the general public at no charge under
-    subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-  from the Corresponding Source as a System Library, need not be included
-  in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-  tangible personal property which is normally used for personal, family,
-  or household purposes, or (2) anything designed or sold for incorporation
-  into a dwelling. In determining whether a product is a consumer product,
-  doubtful cases shall be resolved in favor of coverage. For a particular
-  product received by a particular user, "normally used" refers to a
-  typical or common use of that class of product, regardless of the status
-  of the particular user or of the way in which the particular user
-  actually uses, or expects or is expected to use, the product. A product
-  is a consumer product regardless of whether the product has substantial
-  commercial, industrial or non-consumer uses, unless such uses represent
-  the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-  procedures, authorization keys, or other information required to install
-  and execute modified versions of a covered work in that User Product from
-  a modified version of its Corresponding Source. The information must
-  suffice to ensure that the continued functioning of the modified object
-  code is in no case prevented or interfered with solely because
-  modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-  specifically for use in, a User Product, and the conveying occurs as part
-  of a transaction in which the right of possession and use of the User
-  Product is transferred to the recipient in perpetuity or for a fixed term
-  (regardless of how the transaction is characterized), the Corresponding
-  Source conveyed under this section must be accompanied by the
-  Installation Information. But this requirement does not apply if neither
-  you nor any third party retains the ability to install modified object
-  code on the User Product (for example, the work has been installed in
-  ROM).
-
-  The requirement to provide Installation Information does not include a
-  requirement to continue to provide support service, warranty, or updates
-  for a work that has been modified or installed by the recipient, or for
-  the User Product in which it has been modified or installed. Access
-  to a network may be denied when the modification itself materially
-  and adversely affects the operation of the network or violates the
-  rules and protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided, in
-  accord with this section must be in a format that is publicly documented
-  (and with an implementation available to the public in source code form),
-  and must require no special password or key for unpacking, reading or
-  copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-  License by making exceptions from one or more of its conditions.
-  Additional permissions that are applicable to the entire Program shall be
-  treated as though they were included in this License, to the extent that
-  they are valid under applicable law. If additional permissions apply only
-  to part of the Program, that part may be used separately under those
-  permissions, but the entire Program remains governed by this License
-  without regard to the additional permissions.  When you convey a copy of
-  a covered work, you may at your option remove any additional permissions
-  from that copy, or from any part of it. (Additional permissions may be
-  written to require their own removal in certain cases when you modify the
-  work.) You may place additional permissions on material, added by you to
-  a covered work, for which you have or can give appropriate copyright
-  permission.
-
-  Notwithstanding any other provision of this License, for material you add
-  to a covered work, you may (if authorized by the copyright holders of
-  that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some trade
-    names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that material
-    by anyone who conveys the material (or modified versions of it) with
-    contractual assumptions of liability to the recipient, for any
-    liability that these contractual assumptions directly impose on those
-    licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-  restrictions" within the meaning of section 10. If the Program as you
-  received it, or any part of it, contains a notice stating that it is
-  governed by this License along with a term that is a further restriction,
-  you may remove that term. If a license document contains a further
-  restriction but permits relicensing or conveying under this License, you
-  may add to a covered work material governed by the terms of that license
-  document, provided that the further restriction does not survive such
-  relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you must
-  place, in the relevant source files, a statement of the additional terms
-  that apply to those files, or a notice indicating where to find the
-  applicable terms.  Additional terms, permissive or non-permissive, may be
-  stated in the form of a separately written license, or stated as
-  exceptions; the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-  provided under this License. Any attempt otherwise to propagate or modify
-  it is void, and will automatically terminate your rights under this
-  License (including any patent licenses granted under the third paragraph
-  of section 11).
-
-  However, if you cease all violation of this License, then your license
-  from a particular copyright holder is reinstated (a) provisionally,
-  unless and until the copyright holder explicitly and finally terminates
-  your license, and (b) permanently, if the copyright holder fails to
-  notify you of the violation by some reasonable means prior to 60 days
-  after the cessation.
-
-  Moreover, your license from a particular copyright holder is reinstated
-  permanently if the copyright holder notifies you of the violation by some
-  reasonable means, this is the first time you have received notice of
-  violation of this License (for any work) from that copyright holder, and
-  you cure the violation prior to 30 days after your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-  licenses of parties who have received copies or rights from you under
-  this License. If your rights have been terminated and not permanently
-  reinstated, you do not qualify to receive new licenses for the same
-  material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or run a
-  copy of the Program. Ancillary propagation of a covered work occurring
-  solely as a consequence of using peer-to-peer transmission to receive a
-  copy likewise does not require acceptance. However, nothing other than
-  this License grants you permission to propagate or modify any covered
-  work. These actions infringe copyright if you do not accept this License.
-  Therefore, by modifying or propagating a covered work, you indicate your
-  acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically receives
-  a license from the original licensors, to run, modify and propagate that
-  work, subject to this License. You are not responsible for enforcing
-  compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-  organization, or substantially all assets of one, or subdividing an
-  organization, or merging organizations. If propagation of a covered work
-  results from an entity transaction, each party to that transaction who
-  receives a copy of the work also receives whatever licenses to the work
-  the party's predecessor in interest had or could give under the previous
-  paragraph, plus a right to possession of the Corresponding Source of the
-  work from the predecessor in interest, if the predecessor has it or can
-  get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the rights
-  granted or affirmed under this License. For example, you may not impose a
-  license fee, royalty, or other charge for exercise of rights granted
-  under this License, and you may not initiate litigation (including a
-  cross-claim or counterclaim in a lawsuit) alleging that any patent claim
-  is infringed by making, using, selling, offering for sale, or importing
-  the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-  License of the Program or a work on which the Program is based. The work
-  thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims owned or
-  controlled by the contributor, whether already acquired or hereafter
-  acquired, that would be infringed by some manner, permitted by this
-  License, of making, using, or selling its contributor version, but do not
-  include claims that would be infringed only as a consequence of further
-  modification of the contributor version. For purposes of this definition,
-  "control" includes the right to grant patent sublicenses in a manner
-  consistent with the requirements of this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-  patent license under the contributor's essential patent claims, to make,
-  use, sell, offer for sale, import and otherwise run, modify and propagate
-  the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-  agreement or commitment, however denominated, not to enforce a patent
-  (such as an express permission to practice a patent or covenant not to
-  sue for patent infringement). To "grant" such a patent license to a party
-  means to make such an agreement or commitment not to enforce a patent
-  against the party.
-
-  If you convey a covered work, knowingly relying on a patent license, and
-  the Corresponding Source of the work is not available for anyone to copy,
-  free of charge and under the terms of this License, through a publicly
-  available network server or other readily accessible means, then you must
-  either (1) cause the Corresponding Source to be so available, or (2)
-  arrange to deprive yourself of the benefit of the patent license for this
-  particular work, or (3) arrange, in a manner consistent with the
-  requirements of this License, to extend the patent license to downstream
-  recipients. "Knowingly relying" means you have actual knowledge that, but
-  for the patent license, your conveying the covered work in a country, or
-  your recipient's use of the covered work in a country, would infringe
-  one or more identifiable patents in that country that you have reason
-  to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-  arrangement, you convey, or propagate by procuring conveyance of, a
-  covered work, and grant a patent license to some of the parties receiving
-  the covered work authorizing them to use, propagate, modify or convey a
-  specific copy of the covered work, then the patent license you grant is
-  automatically extended to all recipients of the covered work and works
-  based on it.
-
-  A patent license is "discriminatory" if it does not include within the
-  scope of its coverage, prohibits the exercise of, or is conditioned on
-  the non-exercise of one or more of the rights that are specifically
-  granted under this License. You may not convey a covered work if you are
-  a party to an arrangement with a third party that is in the business of
-  distributing software, under which you make payment to the third party
-  based on the extent of your activity of conveying the work, and under
-  which the third party grants, to any of the parties who would receive the
-  covered work from you, a discriminatory patent license (a) in connection
-  with copies of the covered work conveyed by you (or copies made from
-  those copies), or (b) primarily for and in connection with specific
-  products or compilations that contain the covered work, unless you
-  entered into that arrangement, or that patent license was granted, prior
-  to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting any
-  implied license or other defenses to infringement that may otherwise be
-  available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-  otherwise) that contradict the conditions of this License, they do not
-  excuse you from the conditions of this License. If you cannot use,
-  propagate or convey a covered work so as to satisfy simultaneously your
-  obligations under this License and any other pertinent obligations, then
-  as a consequence you may not use, propagate or convey it at all. For
-  example, if you agree to terms that obligate you to collect a royalty for
-  further conveying from those to whom you convey the Program, the only way
-  you could satisfy both those terms and this License would be to refrain
-  entirely from conveying the Program.
-
-  13. Offering the Program as a Service.
-
-  If you make the functionality of the Program or a modified version
-  available to third parties as a service, you must make the Service Source
-  Code available via network download to everyone at no charge, under the
-  terms of this License. Making the functionality of the Program or
-  modified version available to third parties as a service includes,
-  without limitation, enabling third parties to interact with the
-  functionality of the Program or modified version remotely through a
-  computer network, offering a service the value of which entirely or

 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.

-    implement and manipulate in memory with good performance, making Redis very
-    simple. Redis will continue to explore alternative options (where data can

-4 - We believe in code efficiency. Computers get faster and faster, yet we
-    believe that abusing computing capabilities is not wise: the amount of
-    operations you can do for a given amount of energy remains anyway a
-    significant parameter: it allows to do more with less computers and, at
-    the same time, having a smaller environmental impact. Similarly Redis is
-    able to "scale down" to smaller devices. It is perfectly usable in a
-    Raspberry Pi and other small ARM based computers. Faster code having
-    just the layers of abstractions that are really needed will also result,
-    often, in more predictable performances. We think likewise about memory
-    usage, one of the fundamental goals of the Redis project is to
-    incrementally build more and more memory efficient data structures, so that
-    problems that were not approachable in RAM in the past will be perfectly
-    fine to handle in the future.
+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.

-    of code. Most of the time the best way to fight complexity is by not
-    creating it at all. Complexity is also a form of lock-in: code that is
-    very hard to understand cannot be modified by users in an independent way
-    regardless of the license. One of the main Redis goals is to remain
-    understandable, enough for a single programmer to have a clear idea of how
-    it works in detail just reading the source code for a couple of weeks.
+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 - Threading is not a silver bullet. Instead of making Redis threaded we
-    believe on the idea of an efficient (mostly) single threaded Redis core.
-    Multiple of such cores, that may run in the same computer or may run
-    in multiple computers, are abstracted away as a single big system by
-    higher order protocols and features: Redis Cluster and the upcoming
-    Redis Proxy are our main goals. A shared nothing approach is not just
-    much simpler (see the previous point in this document), is also optimal
-    in NUMA systems. In the specific case of Redis it allows for each instance
-    to have a more limited amount of data, making the Redis persist-by-fork
-    approach more sounding. In the future we may explore parallelism only for
-    I/O, which is the low hanging fruit: minimal complexity could provide an
-    improved single process experience.
+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.

-    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

-
-10 - All the above points are put together in what we call opportunistic
-     programming: trying to get the most for the user with minimal increases
-     in complexity (hanging fruits). Solve 95% of the problem with 5% of the
-     code when it is acceptable. Avoid a fixed schedule but follow the flow of
-     user requests, inspiration, Redis internal readiness for certain features
-     (sometimes many past changes reach a critical point making a previously
-     complex feature very easy to obtain).

+Where to find complete Redis documentation?
+-------------------------------------------
+
+This README is just a fast "quick start" document. You can find more detailed
+documentation at http://redis.io
+
+Building Redis
+--------------
+
+Redis can be compiled and used on Linux, OSX, OpenBSD, NetBSD, FreeBSD.
+We support big endian and little endian architectures.
+
+It may compile on Solaris derived systems (for instance SmartOS) but our
+support for this platform is "best effort" and Redis is not guaranteed to
+work as well as in Linux, OSX, and *BSD there.
+
+It is as simple as:
+
+    % make
+
+You can run a 32 bit Redis binary using:
+
+    % make 32bit
+
+After building Redis is a good idea to test it, using:
+
+    % make test
+
+NOTE: if after building Redis with a 32 bit target you need to rebuild it
+      with a 64 bit target you need to perform a "make clean" in the root
+      directory of the Redis distribution.
+
+Allocator
+---------
+
+Selecting a non-default memory allocator when building Redis is done by setting
+the `MALLOC` environment variable. Redis is compiled and linked against libc
+malloc by default, with the exception of jemalloc being the default on Linux
+systems. This default was picked because jemalloc has proven to have fewer
+fragmentation problems than libc malloc.
+
+To force compiling against libc malloc, use:
+
+    % make MALLOC=libc
+
+To compile against jemalloc on Mac OS X systems, use:
+
+    % make MALLOC=jemalloc
+
+Verbose build
+-------------
+
+Redis will build with a user friendly colorized output by default.
+If you want to see a more verbose output use the following:
+
+    % make V=1
+
+Running Redis
+-------------
+
+To run Redis with the default configuration just type:
+
+    % cd src
+    % ./redis-server
+    
+If you want to provide your redis.conf, you have to run it using an additional
+parameter (the path of the configuration file):
+
+    % cd src
+    % ./redis-server /path/to/redis.conf
+
+It is possible to alter the Redis configuration passing parameters directly
+as options using the command line. Examples:
+
+    % ./redis-server --port 9999 --slaveof 127.0.0.1 6379
+    % ./redis-server /etc/redis/6379.conf --loglevel debug
+
+All the options in redis.conf are also supported as options using the command
+line, with exactly the same name.
+
+Playing with Redis
+------------------
+
+You can use redis-cli to play with Redis. Start a redis-server instance,
+then in another terminal try the following:
+
+    % cd src
+    % ./redis-cli
+    redis> ping
+    PONG
+    redis> set foo bar
+    OK
+    redis> get foo
+    "bar"
+    redis> incr mycounter
+    (integer) 1
+    redis> incr mycounter
+    (integer) 2
+    redis> 
+
+You can find the list of all the available commands here:
+
+    http://redis.io/commands
+
+Installing Redis
+-----------------
+
+In order to install Redis binaries into /usr/local/bin just use:
+
+    % make install
+
+You can use "make PREFIX=/some/other/directory install" if you wish to use a
+different destination.
+
+Make install will just install binaries in your system, but will not configure
+init scripts and configuration files in the appropriate place. This is not
+needed if you want just to play a bit with Redis, but if you are installing
+it the proper way for a production system, we have a script doing this
+for Ubuntu and Debian systems:
+
+    % cd utils
+    % ./install_server
+
+The script will ask you a few questions and will setup everything you need
+to run Redis properly as a background daemon that will start again on
+system reboots.
+
+You'll be able to stop and start Redis using the script named
+/etc/init.d/redis_<portnumber>, for instance /etc/init.d/redis_6379.
+
+Enjoy!

-
-What is Redis?
----
-
-Redis is often referred to as a *data structures* server. What this means is that Redis provides access to mutable data structures via a set of commands, which are sent using a *server-client* model with TCP sockets and a simple protocol. So different processes can query and modify the same data structures in a shared way.
-
-Data structures implemented into Redis have a few special properties:
-
-* Redis cares to store them on disk, even if they are always served and modified into the server memory. This means that Redis is fast, but that it is also non-volatile.
-* The implementation of data structures emphasizes memory efficiency, so data structures inside Redis will likely use less memory compared to the same data structure modelled using a high-level programming language.
-* Redis offers a number of features that are natural to find in a database, like replication, tunable levels of durability, clustering, and high availability.
-
-Another good example is to think of Redis as a more complex version of memcached, where the operations are not just SETs and GETs, but operations that work with complex data types like Lists, Sets, ordered data structures, and so forth.
-
-If you want to know more, this is a list of selected starting points:
-
-* Introduction to Redis data types. https://redis.io/topics/data-types-intro
-* The full list of Redis commands. https://redis.io/commands
-* There is much more inside the official Redis documentation. https://redis.io/documentation
-
-What is Redis Community Edition?
----
-
-Redis OSS was renamed Redis Community Edition (CE) with the v7.4 release.
-
-Redis Ltd. also offers [Redis Software](https://redis.io/enterprise/), a self-managed software with additional compliance, reliability, and resiliency for enterprise scaling,
-and [Redis Cloud](https://redis.io/cloud/), a fully managed service integrated with Google Cloud, Azure, and AWS for production-ready apps.
-
-Read more about the differences between Redis Community Edition and Redis [here](https://redis.io/comparisons/oss-vs-enterprise/).
-
-Building Redis
----
-
-Redis can be compiled and used on Linux, OSX, OpenBSD, NetBSD, FreeBSD.
-We support big endian and little endian architectures, and both 32 bit
-and 64 bit systems.
-
-It may compile on Solaris derived systems (for instance SmartOS) but our
-support for this platform is *best effort* and Redis is not guaranteed to
-work as well as in Linux, OSX, and \*BSD.
-
-It is as simple as:
-
-    % make
-
-To build with TLS support, you'll need OpenSSL development libraries (e.g.
-libssl-dev on Debian/Ubuntu) and run:
-
-    % make BUILD_TLS=yes
-
-To build with systemd support, you'll need systemd development libraries (such 
-as libsystemd-dev on Debian/Ubuntu or systemd-devel on CentOS) and run:
-
-    % make USE_SYSTEMD=yes
-
-To append a suffix to Redis program names, use:
-
-    % make PROG_SUFFIX="-alt"
-
-You can build a 32 bit Redis binary using:
-
-    % make 32bit
-
-After building Redis, it is a good idea to test it using:
-
-    % make test
-
-If TLS is built, running the tests with TLS enabled (you will need `tcl-tls`
-installed):
-
-    % ./utils/gen-test-certs.sh
-    % ./runtest --tls
-
-
-Fixing build problems with dependencies or cached build options
----
-
-Redis has some dependencies which are included in the `deps` directory.
-`make` does not automatically rebuild dependencies even if something in
-the source code of dependencies changes.
-
-When you update the source code with `git pull` or when code inside the
-dependencies tree is modified in any other way, make sure to use the following
-command in order to really clean everything and rebuild from scratch:
-
-    % make distclean
-
-This will clean: jemalloc, lua, hiredis, linenoise and other dependencies.
-
-Also if you force certain build options like 32bit target, no C compiler
-optimizations (for debugging purposes), and other similar build time options,
-those options are cached indefinitely until you issue a `make distclean`
-command.
-
-Fixing problems building 32 bit binaries
----
-
-If after building Redis with a 32 bit target you need to rebuild it
-with a 64 bit target, or the other way around, you need to perform a
-`make distclean` in the root directory of the Redis distribution.
-
-In case of build errors when trying to build a 32 bit binary of Redis, try
-the following steps:
-
-* Install the package libc6-dev-i386 (also try g++-multilib).
-* Try using the following command line instead of `make 32bit`:
-  `make CFLAGS="-m32 -march=native" LDFLAGS="-m32"`
-
-Allocator
----
-
-Selecting a non-default memory allocator when building Redis is done by setting
-the `MALLOC` environment variable. Redis is compiled and linked against libc
-malloc by default, with the exception of jemalloc being the default on Linux
-systems. This default was picked because jemalloc has proven to have fewer
-fragmentation problems than libc malloc.
-
-To force compiling against libc malloc, use:
-
-    % make MALLOC=libc
-
-To compile against jemalloc on Mac OS X systems, use:
-
-    % make MALLOC=jemalloc
-
-Monotonic clock
----
-
-By default, Redis will build using the POSIX clock_gettime function as the
-monotonic clock source.  On most modern systems, the internal processor clock
-can be used to improve performance.  Cautions can be found here: 
-    http://oliveryang.net/2015/09/pitfalls-of-TSC-usage/
-
-To build with support for the processor's internal instruction clock, use:
-
-    % make CFLAGS="-DUSE_PROCESSOR_CLOCK"
-
-Verbose build
----
-
-Redis will build with a user-friendly colorized output by default.
-If you want to see a more verbose output, use the following:

-If you want to provide your redis.conf, you have to run it using an additional
-parameter (the path of the configuration file):

-All the options in redis.conf are also supported as options using the command
-line, with exactly the same name.

-how to use Redis with TLS.
-
-Playing with Redis

-or you just untarred the Redis distribution tar ball. In both the cases
-you are basically one step away from the source code, so here we explain
-the Redis source code layout, what is in each file as a general idea, the
-most important functions and structures inside the Redis server and so forth.
-We keep all the discussion at a high level without digging into the details
-since this document would be huge otherwise and our code base changes
-continuously, but a general idea should be a good starting point to
-understand more. Moreover most of the code is heavily commented and easy
-to follow.
-
-Source code layout
----
-
-The Redis root directory just contains this README, the Makefile which
-calls the real Makefile inside the `src` directory and an example
-configuration for Redis and Redis Sentinel. You can find a few shell
-scripts that are used in order to execute the Redis, Redis Cluster and
-Redis Sentinel unit tests, which are implemented inside the `tests`
-directory.
-
-Inside the root are the following important directories:
-
-* `src`: contains the Redis implementation, written in C.
-* `tests`: contains the unit tests, implemented in Tcl.
-* `deps`: contains libraries Redis uses. Everything needed to compile Redis is inside this directory; your system just needs to provide `libc`, a POSIX compatible interface and a C compiler. Notably `deps` contains a copy of `jemalloc`, which is the default allocator of Redis under Linux. Note that under `deps` there are also things which started with the Redis project, but for which the main repository is not `redis/redis`.
-
-There are a few more directories but they are not very important for our goals
-here. We'll focus mostly on `src`, where the Redis implementation is contained,
-exploring what there is inside each file. The order in which files are
-exposed is the logical one to follow in order to disclose different layers
-of complexity incrementally.
-
-Note: lately Redis was refactored quite a bit. Function names and file
-names have been changed, so you may find that this documentation reflects the
-`unstable` branch more closely. For instance, in Redis 3.0 the `server.c`
-and `server.h` files were named `redis.c` and `redis.h`. However the overall
-structure is the same. Keep in mind that all the new developments and pull
-requests should be performed against the `unstable` branch.
-
-server.h
----
-
-The simplest way to understand how a program works is to understand the
-data structures it uses. So we'll start from the main header file of
-Redis, which is `server.h`.
-
-All the server configuration and in general all the shared state is
-defined in a global structure called `server`, of type `struct redisServer`.
-A few important fields in this structure are:
-
-* `server.db` is an array of Redis databases, where data is stored.
-* `server.commands` is the command table.
-* `server.clients` is a linked list of clients connected to the server.
-* `server.master` is a special client, the master, if the instance is a replica.
-
-There are tons of other fields. Most fields are commented directly inside
-the structure definition.
-
-Another important Redis data structure is the one defining a client.
-In the past it was called `redisClient`, now just `client`. The structure
-has many fields, here we'll just show the main ones:
-```c
-struct client {
-    int fd;
-    sds querybuf;
-    int argc;
-    robj **argv;
-    redisDb *db;
-    int flags;
-    list *reply;
-    // ... many other fields ...
-    char buf[PROTO_REPLY_CHUNK_BYTES];
-}
-```
-The client structure defines a *connected client*:
-
-* The `fd` field is the client socket file descriptor.
-* `argc` and `argv` are populated with the command the client is executing, so that functions implementing a given Redis command can read the arguments.
-* `querybuf` accumulates the requests from the client, which are parsed by the Redis server according to the Redis protocol and executed by calling the implementations of the commands the client is executing.
-* `reply` and `buf` are dynamic and static buffers that accumulate the replies the server sends to the client. These buffers are incrementally written to the socket as soon as the file descriptor is writable.
-
-As you can see in the client structure above, arguments in a command
-are described as `robj` structures. The following is the full `robj`
-structure, which defines a *Redis object*:
-
-```c
-struct redisObject {
-    unsigned type:4;
-    unsigned encoding:4;
-    unsigned lru:LRU_BITS; /* LRU time (relative to global lru_clock) or
-                            * LFU data (least significant 8 bits frequency
-                            * and most significant 16 bits access time). */
-    int refcount;
-    void *ptr;
-};
-```
-
-Basically this structure can represent all the basic Redis data types like
-strings, lists, sets, sorted sets and so forth. The interesting thing is that
-it has a `type` field, so that it is possible to know what type a given
-object has, and a `refcount`, so that the same object can be referenced
-in multiple places without allocating it multiple times. Finally the `ptr`
-field points to the actual representation of the object, which might vary
-even for the same type, depending on the `encoding` used.
-
-Redis objects are used extensively in the Redis internals, however in order
-to avoid the overhead of indirect accesses, recently in many places
-we just use plain dynamic strings not wrapped inside a Redis object.
-
-server.c
----
-
-This is the entry point of the Redis server, where the `main()` function
-is defined. The following are the most important steps in order to startup
-the Redis server.
-
-* `initServerConfig()` sets up the default values of the `server` structure.
-* `initServer()` allocates the data structures needed to operate, setup the listening socket, and so forth.
-* `aeMain()` starts the event loop which listens for new connections.
-
-There are two special functions called periodically by the event loop:
-
-1. `serverCron()` is called periodically (according to `server.hz` frequency), and performs tasks that must be performed from time to time, like checking for timed out clients.
-2. `beforeSleep()` is called every time the event loop fired, Redis served a few requests, and is returning back into the event loop.
-
-Inside server.c you can find code that handles other vital things of the Redis server:
-
-* `call()` is used in order to call a given command in the context of a given client.
-* `activeExpireCycle()` handles eviction of keys with a time to live set via the `EXPIRE` command.
-* `performEvictions()` is called when a new write command should be performed but Redis is out of memory according to the `maxmemory` directive.
-* The global variable `redisCommandTable` defines all the Redis commands, specifying the name of the command, the function implementing the command, the number of arguments required, and other properties of each command.
-
-commands.c
----
-This file is auto generated by utils/generate-command-code.py, the content is based on the JSON files in the src/commands folder.
-These are meant to be the single source of truth about the Redis commands, and all the metadata about them.
-These JSON files are not meant to be used by anyone directly, instead that metadata can be obtained via the `COMMAND` command.
-
-networking.c
----
-
-This file defines all the I/O functions with clients, masters and replicas
-(which in Redis are just special clients):
-
-* `createClient()` allocates and initializes a new client.
-* The `addReply*()` family of functions are used by command implementations in order to append data to the client structure, that will be transmitted to the client as a reply for a given command executed.
-* `writeToClient()` transmits the data pending in the output buffers to the client and is called by the *writable event handler* `sendReplyToClient()`.
-* `readQueryFromClient()` is the *readable event handler* and accumulates data read from the client into the query buffer.
-* `processInputBuffer()` is the entry point in order to parse the client query buffer according to the Redis protocol. Once commands are ready to be processed, it calls `processCommand()` which is defined inside `server.c` in order to actually execute the command.
-* `freeClient()` deallocates, disconnects and removes a client.
-
-aof.c and rdb.c
----
-
-As you can guess from the names, these files implement the RDB and AOF
-persistence for Redis. Redis uses a persistence model based on the `fork()`
-system call in order to create a process with the same (shared) memory
-content of the main Redis process. This secondary process dumps the content
-of the memory on disk. This is used by `rdb.c` to create the snapshots
-on disk and by `aof.c` in order to perform the AOF rewrite when the
-append only file gets too big.
-
-The implementation inside `aof.c` has additional functions in order to
-implement an API that allows commands to append new commands into the AOF
-file as clients execute them.
-
-The `call()` function defined inside `server.c` is responsible for calling
-the functions that in turn will write the commands into the AOF.
-
-db.c
----
-
-Certain Redis commands operate on specific data types; others are general.
-Examples of generic commands are `DEL` and `EXPIRE`. They operate on keys
-and not on their values specifically. All those generic commands are
-defined inside `db.c`.
-
-Moreover `db.c` implements an API in order to perform certain operations
-on the Redis dataset without directly accessing the internal data structures.
-
-The most important functions inside `db.c` which are used in many command
-implementations are the following:
-
-* `lookupKeyRead()` and `lookupKeyWrite()` are used in order to get a pointer to the value associated to a given key, or `NULL` if the key does not exist.
-* `dbAdd()` and its higher level counterpart `setKey()` create a new key in a Redis database.
-* `dbDelete()` removes a key and its associated value.
-* `emptyData()` removes an entire single database or all the databases defined.
-
-The rest of the file implements the generic commands exposed to the client.
-
-object.c
----
-
-The `robj` structure defining Redis objects was already described. Inside
-`object.c` there are all the functions that operate with Redis objects at
-a basic level, like functions to allocate new objects, handle the reference
-counting and so forth. Notable functions inside this file:
-
-* `incrRefCount()` and `decrRefCount()` are used in order to increment or decrement an object reference count. When it drops to 0 the object is finally freed.
-* `createObject()` allocates a new object. There are also specialized functions to allocate string objects having a specific content, like `createStringObjectFromLongLong()` and similar functions.
-
-This file also implements the `OBJECT` command.
-
-replication.c
----
-
-This is one of the most complex files inside Redis, it is recommended to
-approach it only after getting a bit familiar with the rest of the code base.
-In this file there is the implementation of both the master and replica role
-of Redis.
-
-One of the most important functions inside this file is `replicationFeedSlaves()` that writes commands to the clients representing replica instances connected
-to our master, so that the replicas can get the writes performed by the clients:
-this way their data set will remain synchronized with the one in the master.
-
-This file also implements both the `SYNC` and `PSYNC` commands that are
-used in order to perform the first synchronization between masters and
-replicas, or to continue the replication after a disconnection.
-
-Script
----
-
-The script unit is composed of 3 units:
-* `script.c` - integration of scripts with Redis (commands execution, set replication/resp, ...)
-* `script_lua.c` - responsible to execute Lua code, uses `script.c` to interact with Redis from within the Lua code.
-* `function_lua.c` - contains the Lua engine implementation, uses `script_lua.c` to execute the Lua code.
-* `functions.c` - contains Redis Functions implementation (`FUNCTION` command), uses `functions_lua.c` if the function it wants to invoke needs the Lua engine.
-* `eval.c` - contains the `eval` implementation using `script_lua.c` to invoke the Lua code.
-
-
-Other C files
----
-
-* `t_hash.c`, `t_list.c`, `t_set.c`, `t_string.c`, `t_zset.c` and `t_stream.c` contains the implementation of the Redis data types. They implement both an API to access a given data type, and the client command implementations for these data types.
-* `ae.c` implements the Redis event loop, it's a self contained library which is simple to read and understand.
-* `sds.c` is the Redis string library, check https://github.com/antirez/sds for more information.
-* `anet.c` is a library to use POSIX networking in a simpler way compared to the raw interface exposed by the kernel.
-* `dict.c` is an implementation of a non-blocking hash table which rehashes incrementally.
-* `cluster.c` implements the Redis Cluster. Probably a good read only after being very familiar with the rest of the Redis code base. If you want to read `cluster.c` make sure to read the [Redis Cluster specification][4].
-
-[4]: https://redis.io/topics/cluster-spec
-
-Anatomy of a Redis command
----
-
-All the Redis commands are defined in the following way:
-
-```c
-void foobarCommand(client *c) {
-    printf("%s",c->argv[1]->ptr); /* Do something with the argument. */
-    addReply(c,shared.ok); /* Reply something to the client. */
-}
-```
-
-The command function is referenced by a JSON file, together with its metadata, see `commands.c` described above for details.
-The command flags are documented in the comment above the `struct redisCommand` in `server.h`.
-For other details, please refer to the `COMMAND` command. https://redis.io/commands/command/
-
-After the command operates in some way, it returns a reply to the client,
-usually using `addReply()` or a similar function defined inside `networking.c`.
-
-There are tons of command implementations inside the Redis source code
-that can serve as examples of actual commands implementations (e.g. pingCommand). Writing
-a few toy commands can be a good exercise to get familiar with the code base.
-
-There are also many other files not described here, but it is useless to
-cover everything. We just want to help you with the first steps.
-Eventually you'll find your way inside the Redis code base :-)
-
-Enjoy!

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

-This directory contains all Redis dependencies, except for the libc that

-* **Jemalloc** is our memory allocator, used as replacement for libc malloc on Linux by default. It has good performances and excellent fragmentation behavior. This component is upgraded from time to time.
-* **hiredis** is the official C client library for Redis. It is used by redis-cli, redis-benchmark and Redis Sentinel. It is part of the Redis official ecosystem but is developed externally from the Redis repository, so we just upgrade it as needed.
-* **linenoise** is a readline replacement. It is developed by the same authors of Redis but is managed as a separated project and updated as needed.
-* **lua** is Lua 5.1 with minor changes for security and additional libraries.
-* **hdr_histogram** Used for per-command latency tracking histograms.

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

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

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

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

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

-## [1.0.0-rc1](https://github.com/redis/hiredis/tree/v1.0.0-rc1) - (2020-07-29)
-
-_Note:  There were no changes to code between v1.0.0-rc1 and v1.0.0 so see v1.0.0 for changelog_
-
-### 0.14.1 (2020-03-13)
-
-* Adds safe allocation wrappers (CVE-2020-7105, #747, #752) (Michael Grunder)
-
-### 0.14.0 (2018-09-25)
-**BREAKING CHANGES**:
-
-* Change `redisReply.len` to `size_t`, as it denotes the the size of a string
-
-  User code should compare this to `size_t` values as well.
-  If it was used to compare to other values, casting might be necessary or can be removed, if casting was applied before.
-
-* Make string2ll static to fix conflict with Redis (Tom Lee [c3188b])
-* Use -dynamiclib instead of -shared for OSX (Ryan Schmidt [a65537])
-* Use string2ll from Redis w/added tests (Michael Grunder [7bef04, 60f622])
-* Makefile - OSX compilation fixes (Ryan Schmidt [881fcb, 0e9af8])
-* Remove redundant NULL checks (Justin Brewer [54acc8, 58e6b8])
-* Fix bulk and multi-bulk length truncation (Justin Brewer [109197])
-* Fix SIGSEGV in OpenBSD by checking for NULL before calling freeaddrinfo (Justin Brewer [546d94])
-* Several POSIX compatibility fixes (Justin Brewer [bbeab8, 49bbaa, d1c1b6])
-* Makefile - Compatibility fixes (Dimitri Vorobiev [3238cf, 12a9d1])
-* Makefile - Fix make install on FreeBSD (Zach Shipko [a2ef2b])
-* Makefile - don't assume $(INSTALL) is cp (Igor Gnatenko [725a96])
-* Separate side-effect causing function from assert and small cleanup (amallia [b46413, 3c3234])
-* Don't send negative values to `__redisAsyncCommand` (Frederik Deweerdt [706129])
-* Fix leak if setsockopt fails (Frederik Deweerdt [e21c9c])
-* Fix libevent leak (zfz [515228])
-* Clean up GCC warning (Ichito Nagata [2ec774])
-* Keep track of errno in `__redisSetErrorFromErrno()` as snprintf may use it (Jin Qing [25cd88])
-* Solaris compilation fix (Donald Whyte [41b07d])
-* Reorder linker arguments when building examples (Tustfarm-heart [06eedd])
-* Keep track of subscriptions in case of rapid subscribe/unsubscribe (Hyungjin Kim [073dc8, be76c5, d46999])
-* libuv use after free fix (Paul Scott [cbb956])
-* Properly close socket fd on reconnect attempt (WSL [64d1ec])
-* Skip valgrind in OSX tests (Jan-Erik Rediger [9deb78])
-* Various updates for Travis testing OSX (Ted Nyman [fa3774, 16a459, bc0ea5])
-* Update libevent (Chris Xin [386802])
-* Change sds.h for building in C++ projects (Ali Volkan ATLI [f5b32e])
-* Use proper format specifier in redisFormatSdsCommandArgv (Paulino Huerta, Jan-Erik Rediger [360a06, 8655a6])
-* Better handling of NULL reply in example code (Jan-Erik Rediger [1b8ed3])
-* Prevent overflow when formatting an error (Jan-Erik Rediger [0335cb])
-* Compatibility fix for strerror_r (Tom Lee [bb1747])
-* Properly detect integer parse/overflow errors (Justin Brewer [93421f])
-* Adds CI for Windows and cygwin fixes (owent, [6c53d6, 6c3e40])
-* Catch a buffer overflow when formatting the error message
-* Import latest upstream sds. This breaks applications that are linked against the old hiredis v0.13
-* Fix warnings, when compiled with -Wshadow
-* Make hiredis compile in Cygwin on Windows, now CI-tested
-* Bulk and multi-bulk lengths less than -1 or greater than `LLONG_MAX` are now
-  protocol errors. This is consistent with the RESP specification. On 32-bit
-  platforms, the upper bound is lowered to `SIZE_MAX`.
-
-* Remove backwards compatibility macro's
-
-This removes the following old function aliases, use the new name now:
-
-| Old                         | New                    |
-| --------------------------- | ---------------------- |
-| redisReplyReaderCreate      | redisReaderCreate      |
-| redisReplyReaderCreate      | redisReaderCreate      |
-| redisReplyReaderFree        | redisReaderFree        |
-| redisReplyReaderFeed        | redisReaderFeed        |
-| redisReplyReaderGetReply    | redisReaderGetReply    |
-| redisReplyReaderSetPrivdata | redisReaderSetPrivdata |
-| redisReplyReaderGetObject   | redisReaderGetObject   |
-| redisReplyReaderGetError    | redisReaderGetError    |
-
-* The `DEBUG` variable in the Makefile was renamed to `DEBUG_FLAGS`
-
-Previously it broke some builds for people that had `DEBUG` set to some arbitrary value,
-due to debugging other software.
-By renaming we avoid unintentional name clashes.
-
-Simply rename `DEBUG` to `DEBUG_FLAGS` in your environment to make it working again.
-
-### 0.13.3 (2015-09-16)
-
-* Revert "Clear `REDIS_CONNECTED` flag when connection is closed".
-* Make tests pass on FreeBSD (Thanks, Giacomo Olgeni)
-
-
-If the `REDIS_CONNECTED` flag is cleared,
-the async onDisconnect callback function will never be called.
-This causes problems as the disconnect is never reported back to the user.
-
-### 0.13.2 (2015-08-25)
-
-* Prevent crash on pending replies in async code (Thanks, @switch-st)
-* Clear `REDIS_CONNECTED` flag when connection is closed (Thanks, Jerry Jacobs)
-* Add MacOS X addapter (Thanks, @dizzus)
-* Add Qt adapter (Thanks, Pietro Cerutti)
-* Add Ivykis adapter (Thanks, Gergely Nagy)
-
-All adapters are provided as is and are only tested where possible.
-
-### 0.13.1 (2015-05-03)
-
-This is a bug fix release.
-The new `reconnect` method introduced new struct members, which clashed with pre-defined names in pre-C99 code.
-Another commit forced C99 compilation just to make it work, but of course this is not desirable for outside projects.
-Other non-C99 code can now use hiredis as usual again.
-Sorry for the inconvenience.
-
-* Fix memory leak in async reply handling (Salvatore Sanfilippo)

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

-
-**NOTE**:  Hiredis can now return `nan` in addition to `-inf` and `inf` in a `REDIS_REPLY_DOUBLE`.

-
-## Upgrading to `1.0.0`
-
-Version 1.0.0 marks the first stable release of Hiredis.
-It includes some minor breaking changes, mostly to make the exposed API more uniform and self-explanatory.
-It also bundles the updated `sds` library, to sync up with upstream and Redis.
-For code changes see the [Changelog](CHANGELOG.md).
-
-_Note:  As described below, a few member names have been changed but most applications should be able to upgrade with minor code changes and recompiling._

-## IMPORTANT:  Breaking changes from `0.14.1` -> `1.0.0`
-
-* `redisContext` has two additional members (`free_privdata`, and `privctx`).
-* `redisOptions.timeout` has been renamed to `redisOptions.connect_timeout`, and we've added `redisOptions.command_timeout`.
-* `redisReplyObjectFunctions.createArray` now takes `size_t` instead of `int` for its length parameter.
-
-## IMPORTANT:  Breaking changes when upgrading from 0.13.x -> 0.14.x
-
-Bulk and multi-bulk lengths less than -1 or greater than `LLONG_MAX` are now

-Change `redisReply.len` to `size_t`, as it denotes the the size of a string

+struct has an integer `err` field that is non-zero when an the connection is in
 an error state. The field `errstr` will contain a string with a description of
 the error. More information on errors can be found in the **Errors** section.
 After trying to connect to Redis using `redisConnect` you should
 check the `err` field to see if establishing the connection was successful:
 
-```c
-redisContext *c = redisConnect("127.0.0.1", 6379);
-if (c == NULL || c->err) {
-    if (c) {

         // handle error
-    } else {
-        printf("Can't allocate redis context\n");
     }
-}
-```
-
-One can also use `redisConnectWithOptions` which takes a `redisOptions` argument

-to change how the `redisContext` will be configured.
-
-```c
-redisOptions opt = {0};
-
-/* One can set the endpoint with one of our helper macros */
-if (tcp) {
-    REDIS_OPTIONS_SET_TCP(&opt, "localhost", 6379);

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

 ### Sending commands and their callbacks
 
@@ -489,60 +265,43 @@ In an asynchronous context, commands are automatically pipelined due to the natu
 Therefore, unlike the synchronous API, there is only a single way to send commands.
 Because commands are sent to Redis asynchronously, issuing a command requires a callback function
 that is called when the reply is received. Reply callbacks should have the following prototype:
-```c
-void(redisAsyncContext *c, void *reply, void *privdata);
-```
+
+    void(redisAsyncContext *c, void *reply, void *privdata);
+
 The `privdata` argument can be used to curry arbitrary data to the callback from the point where
 the command is initially queued for execution.
 
 The functions that can be used to issue commands in an asynchronous context are:
-```c
-int redisAsyncCommand(
-  redisAsyncContext *ac, redisCallbackFn *fn, void *privdata,
-  const char *format, ...);
-int redisAsyncCommandArgv(
-  redisAsyncContext *ac, redisCallbackFn *fn, void *privdata,

+      redisAsyncContext *ac, redisCallbackFn *fn, void *privdata,
+      int argc, const char **argv, const size_t *argvlen);
+
 Both functions work like their blocking counterparts. The return value is `REDIS_OK` when the command
 was successfully added to the output buffer and `REDIS_ERR` otherwise. Example: when the connection
 is being disconnected per user-request, no new commands may be added to the output buffer and `REDIS_ERR` is
 returned on calls to the `redisAsyncCommand` family.

+for a command is non-`NULL`, the memory is free'd immediately following the callback: the reply is only

 All pending callbacks are called with a `NULL` reply when the context encountered an error.
 
-For every command issued, with the exception of **SUBSCRIBE** and **PSUBSCRIBE**, the callback is
-called exactly once.  Even if the context object id disconnected or deleted, every pending callback
-will be called with a `NULL` reply.
-
-For **SUBSCRIBE** and **PSUBSCRIBE**, the callbacks may be called repeatedly until an `unsubscribe`
-message arrives.  This will be the last invocation of the callback. In case of error, the callbacks
-may receive a final `NULL` reply instead.

-```c
-void redisAsyncDisconnect(redisAsyncContext *ac);

 When this function is called, the connection is **not** immediately terminated. Instead, new
 commands are no longer accepted and the connection is only terminated when all pending commands
 have been written to the socket, their respective replies have been read and their respective
 callbacks have been executed. After this, the disconnection callback is executed with the
-`REDIS_OK` status and the context object is freed.

-```c

-## SSL/TLS Support
-
-### Building
-
-SSL/TLS support is not built by default and requires an explicit flag:
-
-    make USE_SSL=1
-
-This requires OpenSSL development package (e.g. including header files to be
-available.
-
-When enabled, SSL/TLS support is built into extra `libhiredis_ssl.a` and
-`libhiredis_ssl.so` static/dynamic libraries. This leaves the original libraries
-unaffected so no additional dependencies are introduced.
-
-### Using it
-
-First, you'll need to make sure you include the SSL header file:
-
-```c
-#include <hiredis/hiredis.h>
-#include <hiredis/hiredis_ssl.h>
-```
-
-You will also need to link against `libhiredis_ssl`, **in addition** to
-`libhiredis` and add `-lssl -lcrypto` to satisfy its dependencies.
-
-Hiredis implements SSL/TLS on top of its normal `redisContext` or
-`redisAsyncContext`, so you will need to establish a connection first and then
-initiate an SSL/TLS handshake.
-
-#### Hiredis OpenSSL Wrappers
-
-Before Hiredis can negotiate an SSL/TLS connection, it is necessary to
-initialize OpenSSL and create a context. You can do that in two ways:
-
-1. Work directly with the OpenSSL API to initialize the library's global context
-   and create `SSL_CTX *` and `SSL *` contexts. With an `SSL *` object you can
-   call `redisInitiateSSL()`.
-2. Work with a set of Hiredis-provided wrappers around OpenSSL, create a
-   `redisSSLContext` object to hold configuration and use
-   `redisInitiateSSLWithContext()` to initiate the SSL/TLS handshake.
-
-```c
-/* An Hiredis SSL context. It holds SSL configuration and can be reused across
- * many contexts.
- */
-redisSSLContext *ssl_context;
-
-/* An error variable to indicate what went wrong, if the context fails to
- * initialize.
- */
-redisSSLContextError ssl_error = REDIS_SSL_CTX_NONE;
-
-/* Initialize global OpenSSL state.
- *
- * You should call this only once when your app initializes, and only if
- * you don't explicitly or implicitly initialize OpenSSL it elsewhere.
- */
-redisInitOpenSSL();
-
-/* Create SSL context */
-ssl_context = redisCreateSSLContext(
-    "cacertbundle.crt",     /* File name of trusted CA/ca bundle file, optional */
-    "/path/to/certs",       /* Path of trusted certificates, optional */
-    "client_cert.pem",      /* File name of client certificate file, optional */
-    "client_key.pem",       /* File name of client private key, optional */
-    "redis.mydomain.com",   /* Server name to request (SNI), optional */
-    &ssl_error);
-
-if(ssl_context == NULL || ssl_error != REDIS_SSL_CTX_NONE) {
-    /* Handle error and abort... */
-    /* e.g.
-    printf("SSL error: %s\n",
-        (ssl_error != REDIS_SSL_CTX_NONE) ?
-            redisSSLContextGetError(ssl_error) : "Unknown error");
-    // Abort
-    */
-}
-
-/* Create Redis context and establish connection */
-c = redisConnect("localhost", 6443);
-if (c == NULL || c->err) {
-    /* Handle error and abort... */
-}
-
-/* Negotiate SSL/TLS */
-if (redisInitiateSSLWithContext(c, ssl_context) != REDIS_OK) {
-    /* Handle error, in c->err / c->errstr */

-## RESP3 PUSH replies
-Redis 6.0 introduced PUSH replies with the reply-type `>`.  These messages are generated spontaneously and can arrive at any time, so must be handled using callbacks.
-
-### Default behavior
-Hiredis installs handlers on `redisContext` and `redisAsyncContext` by default, which will intercept and free any PUSH replies detected.  This means existing code will work as-is after upgrading to Redis 6 and switching to `RESP3`.
-
-### Custom PUSH handler prototypes
-The callback prototypes differ between `redisContext` and `redisAsyncContext`.
-
-#### redisContext
-```c
-void my_push_handler(void *privdata, void *reply) {
-    /* Handle the reply */
-
-    /* Note: We need to free the reply in our custom handler for
-             blocking contexts.  This lets us keep the reply if
-             we want. */
-    freeReplyObject(reply);
-}
-```
-
-#### redisAsyncContext
-```c
-void my_async_push_handler(redisAsyncContext *ac, void *reply) {
-    /* Handle the reply */
-
-    /* Note:  Because async hiredis always frees replies, you should
-              not call freeReplyObject in an async push callback. */
-}
-```
-
-### Installing a custom handler
-There are two ways to set your own PUSH handlers.
-
-1. Set `push_cb` or `async_push_cb` in the `redisOptions` struct and connect with `redisConnectWithOptions` or `redisAsyncConnectWithOptions`.
-    ```c
-    redisOptions = {0};
-    REDIS_OPTIONS_SET_TCP(&options, "127.0.0.1", 6379);
-    options->push_cb = my_push_handler;
-    redisContext *context = redisConnectWithOptions(&options);
-    ```
-2.  Call `redisSetPushCallback` or `redisAsyncSetPushCallback` on a connected context.
-    ```c
-    redisContext *context = redisConnect("127.0.0.1", 6379);
-    redisSetPushCallback(context, my_push_handler);
-    ```
-
-    _Note `redisSetPushCallback` and `redisAsyncSetPushCallback` both return any currently configured handler,  making it easy to override and then return to the old value._
-
-### Specifying no handler
-If you have a unique use-case where you don't want hiredis to automatically intercept and free PUSH replies, you will want to configure no handler at all.  This can be done in two ways.
-1.  Set the `REDIS_OPT_NO_PUSH_AUTOFREE` flag in `redisOptions` and leave the callback function pointer `NULL`.
-    ```c
-    redisOptions = {0};
-    REDIS_OPTIONS_SET_TCP(&options, "127.0.0.1", 6379);
-    options->options |= REDIS_OPT_NO_PUSH_AUTOFREE;
-    redisContext *context = redisConnectWithOptions(&options);
-    ```
-3.  Call `redisSetPushCallback` with `NULL` once connected.
-    ```c
-    redisContext *context = redisConnect("127.0.0.1", 6379);
-    redisSetPushCallback(context, NULL);
-    ```
-
-    _Note:  With no handler configured, calls to `redisCommand` may generate more than one reply, so this strategy is only applicable when there's some kind of blocking `redisGetReply()` loop (e.g. `MONITOR` or `SUBSCRIBE` workloads)._
-
-## Allocator injection
-
-Hiredis uses a pass-thru structure of function pointers defined in [alloc.h](https://github.com/redis/hiredis/blob/f5d25850/alloc.h#L41) that contain the currently configured allocation and deallocation functions.  By default they just point to libc (`malloc`, `calloc`, `realloc`, etc).
-
-### Overriding
-
-One can override the allocators like so:
-
-```c
-hiredisAllocFuncs myfuncs = {
-    .mallocFn = my_malloc,
-    .callocFn = my_calloc,
-    .reallocFn = my_realloc,
-    .strdupFn = my_strdup,
-    .freeFn = my_free,
-};
-
-// Override allocators (function returns current allocators if needed)
-hiredisAllocFuncs orig = hiredisSetAllocators(&myfuncs);
-```
-
-To reset the allocators to their default libc function simply call:
-
-```c
-hiredisResetAllocators();
-```
