# We set commands.c's merge driver to `binary` so when it conflicts during a
# merge git will leave the local version unmodified. This way our Makefile
# will rebuild it based on src/commands/*.json before trying to compile it.
# Otherwise the file gets modified and gets the same timestamp as the .json

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

# How to provide a patch for a new feature
1. If it is a major feature or a semantical change, write an RCP (Redis Change Proposal). Check the documentation here: https://github.com/redis/redis-rcp
2. If in step 1 you get an acknowledge from the project leaders, use the
following procedure to submit a patch:
a. Fork Redis on github ( http://help.github.com/fork-a-repo/ )
b. Create a topic branch (git checkout -b my_branch)
c. Push to your branch (git push origin my_branch)
d. Initiate a pull request on github ( http://help.github.com/send-pull-requests/ )
e. Done :)
For minor fixes just open a pull request on Github.
Thanks!

By contributing code to the Redis project in any form you agree to the Redis Software Grant and
Contributor License Agreement attached below. Only contributions made under the Redis Software Grant
and Contributor License Agreement may be accepted by Redis, and any contribution is subject to the
terms of the Redis dual-license under RSALv2/SSPLv1 as described in the LICENSE.txt file included in
the Redis source distribution.
# REDIS SOFTWARE GRANT AND CONTRIBUTOR LICENSE AGREEMENT
To specify the intellectual property license granted in any Contribution, Redis Ltd., ("**Redis**")
requires a Software Grant and Contributor License Agreement ("**Agreement**"). This Agreement is for
your protection as a contributor as well as the protection of Redis and its users; it does not
change your rights to use your own Contribution for any other purpose.
By making any Contribution, You accept and agree to the following terms and conditions for the
Contribution. Except for the license granted in this Agreement to Redis and the recipients of the
software distributed by Redis, You reserve all right, title, and interest in and to Your
Contribution.
1. **Definitions**
1.1. "**You**" (or "**Your**") means the copyright owner or legal entity authorized by the
copyright owner that is entering into this Agreement with Redis. For legal entities, the entity
making a Contribution and all other entities that Control, are Controlled by, or are under
common Control with that entity are considered to be a single contributor. For the purposes of
this definition, "**Control**" means (i) the power, direct or indirect, to cause the direction
or management of such entity, whether by contract or otherwise, or (ii) ownership of fifty
percent (50%) or more of the outstanding shares, or (iii) beneficial ownership of such entity.
1.2. "**Contribution**" means the code, documentation, or any original work of authorship,
including any modifications or additions to an existing work described above.
2. "**Work**" means any software project stewarded by Redis.
3. **Grant of Copyright License**. Subject to the terms and conditions of this Agreement, You grant
to Redis and to the recipients of the software distributed by Redis a perpetual, worldwide,
non-exclusive, no-charge, royalty-free, irrevocable copyright license to reproduce, prepare
derivative works of, publicly display, publicly perform, sublicense, and distribute Your
Contribution and such derivative works.
4. **Grant of Patent License**. Subject to the terms and conditions of this Agreement, You grant to
Redis and to the recipients of the software distributed by Redis a perpetual, worldwide,
non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent
license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable by You that are necessarily
infringed by Your Contribution alone or by a combination of Your Contribution with the Work to
which such Contribution was submitted. If any entity institutes patent litigation against You or
any other entity (including a cross-claim or counterclaim in a lawsuit) alleging that your
Contribution, or the Work to which you have contributed, constitutes a direct or contributory
patent infringement, then any patent licenses granted to the claimant entity under this Agreement
for that Contribution or Work terminate as of the date such litigation is filed.
5. **Representations and Warranties**. You represent and warrant that: (i) You are legally entitled
to grant the above licenses; and (ii) if You are an entity, each employee or agent designated by
You is authorized to submit the Contribution on behalf of You; and (iii) your Contribution is
Your original work, and that it will not infringe on any third party's intellectual property
right(s).
6. **Disclaimer**. You are not expected to provide support for Your Contribution, except to the
extent You desire to provide support. You may provide support for free, for a fee, or not at all.
Unless required by applicable law or agreed to in writing, You provide Your Contribution on an
"AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
including, without limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT,
MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.
7. **Enforceability**. Nothing in this Agreement will be construed as creating any joint venture,
employment relationship, or partnership between You and Redis. If any provision of this Agreement
is held to be unenforceable, the remaining provisions of this Agreement will not be affected.
This represents the entire agreement between You and Redis relating to the Contribution.

# 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.

Starting on March 20th, 2024, Redis follows a dual-licensing model with all Redis project code
contributions under version 7.4 and subsequent releases governed by the Redis Software Grant and
Contributor License Agreement. After this date, contributions are subject to the user's choice of
the Redis Source Available License v2 (RSALv2) or the Server Side Public License v1 (SSPLv1), as
follows:

organization.
Your Licenses: means all the Licenses granted to You for the Software
under this Agreement.
License
-------
The Licensor grants You a non-exclusive, royalty-free, worldwide,
non-sublicensable, non-transferable license to use, copy, distribute,
make available, and prepare derivative works of the Software, in each
case subject to the limitations and conditions below.
Limitations
-----------
You may not make the functionality of the Software or a Modified version
available to third parties as a service or distribute the Software or a
Modified version in a manner that makes the functionality of the
Software available to third parties.
Making the functionality of the Software or Modified version available
to third parties includes, without limitation, enabling third parties to
interact with the functionality of the Software or Modified version in
distributed form or remotely through a computer network, offering a
product or service, the value of which entirely or primarily derives
from the value of the Software or Modified version, or offering a
product or service that accomplishes for users the primary purpose of
the Software or Modified version.
You may not alter, remove, or obscure any licensing, copyright, or other
notices of the Licensor in the Software. Any use of the Licensor's
Trademarks is subject to applicable law.

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

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.

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.

Redis internals
===
If you are reading this README you are likely in front of a GitHub page
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].

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 :-)

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

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

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

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

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

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

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

* 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)
* Rename struct member to avoid name clash with pre-c99 code (Alex Balashov, ncopa)
### 0.13.0 (2015-04-16)
This release adds a minimal Windows compatibility layer.
The parser, standalone since v0.12.0, can now be compiled on Windows
(and thus used in other client libraries as well)
* Windows compatibility layer for parser code (tzickel)
* Properly escape data printed to PKGCONF file (Dan Skorupski)
* Fix tests when assert() undefined (Keith Bennett, Matt Stancliff)
* Implement a reconnect method for the client context, this changes the structure of `redisContext` (Aaron Bedra)
### 0.12.1 (2015-01-26)
* Fix `make install`: DESTDIR support, install all required files, install PKGCONF in proper location
* Fix `make test` as 32 bit build on 64 bit platform
### 0.12.0 (2015-01-22)
* Add optional KeepAlive support
* Try again on EINTR errors
* Add libuv adapter
* Add IPv6 support
* Remove possibility of multiple close on same fd
* Add ability to bind source address on connect
* Add redisConnectFd() and redisFreeKeepFd()
* Fix getaddrinfo() memory leak
* Free string if it is unused (fixes memory leak)
* Improve redisAppendCommandArgv performance 2.5x
* Add support for SO_REUSEADDR
* Fix redisvFormatCommand format parsing
* Add GLib 2.0 adapter
* Refactor reading code into read.c
* Fix errno error buffers to not clobber errors
* Generate pkgconf during build
* Silence _BSD_SOURCE warnings
* Improve digit counting for multibulk creation
### 0.11.0
* Increase the maximum multi-bulk reply depth to 7.

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

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

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

* **`REDIS_REPLY_DOUBLE`**:
* The command replied with a double-precision floating point number.
The value is stored as a string in the `str` member, and can be converted with `strtod` or similar.

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

connection is disconnected (either because of an error or per user request). This function should
have the following prototype:
```c
void(const redisAsyncContext *c, int status);
```
On a *connect*, the `status` argument is set to `REDIS_OK` if the connection attempt succeeded. In this
case, the context is ready to accept commands. If it is called with `REDIS_ERR` then the
connection attempt failed. The `err` field in the context can be accessed to find out the cause of the error.
After a failed connection attempt, the context object is automatically freed by the library after calling
the connect callback. This may be a good point to create a new context and retry the connection.
void(const redisAsyncContext *c, int status);
On a disconnect, the `status` argument is set to `REDIS_OK` when disconnection was initiated by the
user, or `REDIS_ERR` when the disconnection was caused by an error. When it is `REDIS_ERR`, the `err`
field in the context can be accessed to find out the cause of the error.
The context object is always freed after the disconnect callback fired. When a reconnect is needed,
The context object is always free'd after the disconnect callback fired. When a reconnect is needed,
the disconnect callback is a good point to do so.
Setting the connect or disconnect callbacks can only be done once per context. For subsequent calls the
api will return `REDIS_ERR`. The function to set the callbacks have the following prototype:
```c
/* Alternatively you can use redisAsyncSetConnectCallbackNC which will be passed a non-const
redisAsyncContext* on invocation (e.g. allowing writes to the privdata member). */
int redisAsyncSetConnectCallback(redisAsyncContext *ac, redisConnectCallback *fn);
int redisAsyncSetDisconnectCallback(redisAsyncContext *ac, redisDisconnectCallback *fn);
```
`ac->data` may be used to pass user data to both callbacks. A typical implementation
might look something like this:
```c
void appOnConnect(redisAsyncContext *c, int status)
{
myAppData *appData = (myAppData*)c->data; /* get my application specific context*/
appData->connecting = 0;
if (status == REDIS_OK) {
appData->connected = 1;
} else {
appData->connected = 0;
appData->err = c->err;
appData->context = NULL; /* avoid stale pointer when callback returns */
}
appAttemptReconnect();
}
Setting the disconnect callback can only be done once per context. For subsequent calls it will
return `REDIS_ERR`. The function to set the disconnect callback has the following prototype:
void appOnDisconnect(redisAsyncContext *c, int status)
{
myAppData *appData = (myAppData*)c->data; /* get my application specific context*/
appData->connected = 0;
appData->err = c->err;
appData->context = NULL; /* avoid stale pointer when callback returns */
if (status == REDIS_OK) {
appNotifyDisconnectCompleted(mydata);
} else {
appNotifyUnexpectedDisconnect(mydata);
appAttemptReconnect();
}
}
```
int redisAsyncSetDisconnectCallback(redisAsyncContext *ac, redisDisconnectCallback *fn);
### Sending commands and their callbacks
@@ -489,60 +267,43 @@ In an asynchronous context, commands are automatically pipelined due to the natu
Therefore, unlike the synchronous API, there is only a single way to send commands.
Because commands are sent to Redis asynchronously, issuing a command requires a callback function
that is called when the reply is received. Reply callbacks should have the following prototype:
```c
void(redisAsyncContext *c, void *reply, void *privdata);
```
void(redisAsyncContext *c, void *reply, void *privdata);
The `privdata` argument can be used to curry arbitrary data to the callback from the point where
the command is initially queued for execution.
The functions that can be used to issue commands in an asynchronous context are:
```c
int redisAsyncCommand(
redisAsyncContext *ac, redisCallbackFn *fn, void *privdata,
const char *format, ...);
int redisAsyncCommandArgv(
redisAsyncContext *ac, redisCallbackFn *fn, void *privdata,
int argc, const char **argv, const size_t *argvlen);
```
int redisAsyncCommand(
redisAsyncContext *ac, redisCallbackFn *fn, void *privdata,
const char *format, ...);
int redisAsyncCommandArgv(
redisAsyncContext *ac, redisCallbackFn *fn, void *privdata,
int argc, const char **argv, const size_t *argvlen);
Both functions work like their blocking counterparts. The return value is `REDIS_OK` when the command
was successfully added to the output buffer and `REDIS_ERR` otherwise. Example: when the connection
is being disconnected per user-request, no new commands may be added to the output buffer and `REDIS_ERR` is
returned on calls to the `redisAsyncCommand` family.
If the reply for a command with a `NULL` callback is read, it is immediately freed. When the callback
for a command is non-`NULL`, the memory is freed immediately following the callback: the reply is only
If the reply for a command with a `NULL` callback is read, it is immediately free'd. When the callback
for a command is non-`NULL`, the memory is free'd immediately following the callback: the reply is only
valid for the duration of the callback.
All pending callbacks are called with a `NULL` reply when the context encountered an error.
For every command issued, with the exception of **SUBSCRIBE** and **PSUBSCRIBE**, the callback is
called exactly once. Even if the context object id disconnected or deleted, every pending callback
will be called with a `NULL` reply.
For **SUBSCRIBE** and **PSUBSCRIBE**, the callbacks may be called repeatedly until an `unsubscribe`
message arrives. This will be the last invocation of the callback. In case of error, the callbacks
may receive a final `NULL` reply instead.
### Disconnecting
An asynchronous connection can be terminated using:
```c
void redisAsyncDisconnect(redisAsyncContext *ac);
```
void redisAsyncDisconnect(redisAsyncContext *ac);
When this function is called, the connection is **not** immediately terminated. Instead, new
commands are no longer accepted and the connection is only terminated when all pending commands
have been written to the socket, their respective replies have been read and their respective
callbacks have been executed. After this, the disconnection callback is executed with the
`REDIS_OK` status and the context object is freed.
The connection can be forcefully disconnected using
```c
void redisAsyncFree(redisAsyncContext *ac);
```
In this case, nothing more is written to the socket, all pending callbacks are called with a `NULL`
reply and the disconnection callback is called with `REDIS_OK`, after which the context object
is freed.
`REDIS_OK` status and the context object is free'd.

For instance if you have a normal Redis context you can set the maximum idle
buffer to zero (unlimited) just with:
```c

This should be done only in order to maximize performances when working with
large payloads. The context should be set back to `REDIS_READER_MAX_BUF` again
as soon as possible in order to prevent allocation of useless memory.
### Reader max array elements
By default the hiredis reply parser sets the maximum number of multi-bulk elements
to 2^32 - 1 or 4,294,967,295 entries. If you need to process multi-bulk replies
with more than this many elements you can set the value higher or to zero, meaning
unlimited with:
```c

## 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();
```
