All rights reserved.
1. DEFINITIONS
Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met:
"Contribution" means:
Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer.
Redistributions in binary form must reproduce the above copyright notice, this list of conditions and the following disclaimer in the documentation and/or other materials provided with the distribution.
Neither the name of the Eclipse Foundation, Inc. nor the names of its contributors may be used to endorse or promote products derived from this software without specific prior written permission.
a) in the case of the initial Contributor, the initial content
Distributed under this Agreement, and
THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED. IN NO EVENT SHALL THE COPYRIGHT OWNER OR CONTRIBUTORS BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO, PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, OR PROFITS; OR BUSINESS INTERRUPTION) HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OF THIS SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.
b) in the case of each subsequent Contributor:
i) changes to the Program, and
ii) additions to the Program;
where such changes and/or additions to the Program originate from
and are Distributed by that particular Contributor. A Contribution
"originates" from a Contributor if it was added to the Program by
such Contributor itself or anyone acting on such Contributor's behalf.
Contributions do not include changes or additions to the Program that
are not Modified Works.
"Contributor" means any person or entity that Distributes the Program.
"Licensed Patents" mean patent claims licensable by a Contributor which
are necessarily infringed by the use or sale of its Contribution alone
or when combined with the Program.
"Program" means the Contributions Distributed in accordance with this
Agreement.
"Recipient" means anyone who receives the Program under this Agreement
or any Secondary License (as applicable), including Contributors.
"Derivative Works" shall mean any work, whether in Source Code or other
form, that is based on (or derived from) the Program and for which the
editorial revisions, annotations, elaborations, or other modifications
represent, as a whole, an original work of authorship.
"Modified Works" shall mean any work in Source Code or other form that
results from an addition to, deletion from, or modification of the
contents of the Program, including, for purposes of clarity any new file
in Source Code form that contains any contents of the Program. Modified
Works shall not include works that contain only declarations,
interfaces, types, classes, structures, or files of the Program solely
in each case in order to link to, bind by name, or subclass the Program
or Modified Works thereof.
"Distribute" means the acts of a) distributing or b) making available
in any manner that enables the transfer of a copy.
"Source Code" means the form of a Program preferred for making
modifications, including but not limited to software source code,
documentation source, and configuration files.
"Secondary License" means either the GNU General Public License,
Version 2.0, or any later versions of that license, including any
exceptions or additional permissions as identified by the initial
Contributor.
2. GRANT OF RIGHTS
a) Subject to the terms of this Agreement, each Contributor hereby
grants Recipient a non-exclusive, worldwide, royalty-free copyright
license to reproduce, prepare Derivative Works of, publicly display,
publicly perform, Distribute and sublicense the Contribution of such
Contributor, if any, and such Derivative Works.
b) Subject to the terms of this Agreement, each Contributor hereby
grants Recipient a non-exclusive, worldwide, royalty-free patent
license under Licensed Patents to make, use, sell, offer to sell,
import and otherwise transfer the Contribution of such Contributor,
if any, in Source Code or other form. This patent license shall
apply to the combination of the Contribution and the Program if, at
the time the Contribution is added by the Contributor, such addition
of the Contribution causes such combination to be covered by the
Licensed Patents. The patent license shall not apply to any other
combinations which include the Contribution. No hardware per se is
licensed hereunder.
c) Recipient understands that although each Contributor grants the
licenses to its Contributions set forth herein, no assurances are
provided by any Contributor that the Program does not infringe the
patent or other intellectual property rights of any other entity.
Each Contributor disclaims any liability to Recipient for claims
brought by any other entity based on infringement of intellectual
property rights or otherwise. As a condition to exercising the
rights and licenses granted hereunder, each Recipient hereby
assumes sole responsibility to secure any other intellectual
property rights needed, if any. For example, if a third party
patent license is required to allow Recipient to Distribute the
Program, it is Recipient's responsibility to acquire that license
before distributing the Program.
d) Each Contributor represents that to its knowledge it has
sufficient copyright rights in its Contribution, if any, to grant
the copyright license set forth in this Agreement.
e) Notwithstanding the terms of any Secondary License, no
Contributor makes additional grants to any Recipient (other than
those set forth in this Agreement) as a result of such Recipient's
receipt of the Program under the terms of a Secondary License
(if permitted under the terms of Section 3).
3. REQUIREMENTS
3.1 If a Contributor Distributes the Program in any form, then:
a) the Program must also be made available as Source Code, in
accordance with section 3.2, and the Contributor must accompany
the Program with a statement that the Source Code for the Program
is available under this Agreement, and informs Recipients how to
obtain it in a reasonable manner on or through a medium customarily
used for software exchange; and
b) the Contributor may Distribute the Program under a license
different than this Agreement, provided that such license:
i) effectively disclaims on behalf of all other Contributors all
warranties and conditions, express and implied, including
warranties or conditions of title and non-infringement, and
implied warranties or conditions of merchantability and fitness
for a particular purpose;
ii) effectively excludes on behalf of all other Contributors all
liability for damages, including direct, indirect, special,
incidental and consequential damages, such as lost profits;
iii) does not attempt to limit or alter the recipients' rights
in the Source Code under section 3.2; and
iv) requires any subsequent distribution of the Program by any
party to be under a license that satisfies the requirements
of this section 3.
3.2 When the Program is Distributed as Source Code:
a) it must be made available under this Agreement, or if the
Program (i) is combined with other material in a separate file or
files made available under a Secondary License, and (ii) the initial
Contributor attached to the Source Code the notice described in
Exhibit A of this Agreement, then the Program may be made available
under the terms of such Secondary Licenses, and
b) a copy of this Agreement must be included with each copy of
the Program.
3.3 Contributors may not remove or alter any copyright, patent,
trademark, attribution notices, disclaimers of warranty, or limitations
of liability ("notices") contained within the Program from any copy of
the Program which they Distribute, provided that Contributors may add
their own appropriate notices.
4. COMMERCIAL DISTRIBUTION
Commercial distributors of software may accept certain responsibilities
with respect to end users, business partners and the like. While this
license is intended to facilitate the commercial use of the Program,
the Contributor who includes the Program in a commercial product
offering should do so in a manner which does not create potential
liability for other Contributors. Therefore, if a Contributor includes
the Program in a commercial product offering, such Contributor
("Commercial Contributor") hereby agrees to defend and indemnify every
other Contributor ("Indemnified Contributor") against any losses,
damages and costs (collectively "Losses") arising from claims, lawsuits
and other legal actions brought by a third party against the Indemnified
Contributor to the extent caused by the acts or omissions of such
Commercial Contributor in connection with its distribution of the Program
in a commercial product offering. The obligations in this section do not
apply to any claims or Losses relating to any actual or alleged
intellectual property infringement. In order to qualify, an Indemnified
Contributor must: a) promptly notify the Commercial Contributor in
writing of such claim, and b) allow the Commercial Contributor to control,
and cooperate with the Commercial Contributor in, the defense and any
related settlement negotiations. The Indemnified Contributor may
participate in any such claim at its own expense.
For example, a Contributor might include the Program in a commercial
product offering, Product X. That Contributor is then a Commercial
Contributor. If that Commercial Contributor then makes performance
claims, or offers warranties related to Product X, those performance
claims and warranties are such Commercial Contributor's responsibility
alone. Under this section, the Commercial Contributor would have to
defend claims against the other Contributors related to those performance
claims and warranties, and if a court requires any other Contributor to
pay any damages as a result, the Commercial Contributor must pay
those damages.
5. NO WARRANTY
EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
PERMITTED BY APPLICABLE LAW, THE PROGRAM IS PROVIDED 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. Each Recipient is solely responsible for determining the
appropriateness of using and distributing the Program and assumes all
risks associated with its exercise of rights under this Agreement,
including but not limited to the risks and costs of program errors,
compliance with applicable laws, damage to or loss of data, programs
or equipment, and unavailability or interruption of operations.
6. DISCLAIMER OF LIABILITY
EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
PERMITTED BY APPLICABLE LAW, NEITHER RECIPIENT NOR ANY CONTRIBUTORS
SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,
EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST
PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN
CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE)
ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE
EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
7. GENERAL
If any provision of this Agreement is invalid or unenforceable under
applicable law, it shall not affect the validity or enforceability of
the remainder of the terms of this Agreement, and without further
action by the parties hereto, such provision shall be reformed to the
minimum extent necessary to make such provision valid and enforceable.
If Recipient institutes patent litigation against any entity
(including a cross-claim or counterclaim in a lawsuit) alleging that the
Program itself (excluding combinations of the Program with other software
or hardware) infringes such Recipient's patent(s), then such Recipient's
rights granted under Section 2(b) shall terminate as of the date such
litigation is filed.
All Recipient's rights under this Agreement shall terminate if it
fails to comply with any of the material terms or conditions of this
Agreement and does not cure such failure in a reasonable period of
time after becoming aware of such noncompliance. If all Recipient's
rights under this Agreement terminate, Recipient agrees to cease use
and distribution of the Program as soon as reasonably practicable.
However, Recipient's obligations under this Agreement and any licenses
granted by Recipient relating to the Program shall continue and survive.
Everyone is permitted to copy and distribute copies of this Agreement,
but in order to avoid inconsistency the Agreement is copyrighted and
may only be modified in the following manner. The Agreement Steward
reserves the right to publish new versions (including revisions) of
this Agreement from time to time. No one other than the Agreement
Steward has the right to modify this Agreement. The Eclipse Foundation
is the initial Agreement Steward. The Eclipse Foundation may assign the
responsibility to serve as the Agreement Steward to a suitable separate
entity. Each new version of the Agreement will be given a distinguishing
version number. The Program (including Contributions) may always be
Distributed subject to the version of the Agreement under which it was
received. In addition, after a new version of the Agreement is published,
Contributor may elect to Distribute the Program (including its
Contributions) under the new version.
Except as expressly stated in Sections 2(a) and 2(b) above, Recipient
receives no rights or licenses to the intellectual property of any
Contributor under this Agreement, whether expressly, by implication,
estoppel or otherwise. All rights in the Program not expressly granted
under this Agreement are reserved. Nothing in this Agreement is intended
to be enforceable by any entity that is not a Contributor or Recipient.
No third-party beneficiary rights are created under this Agreement.
Exhibit A - Form of Secondary Licenses Notice
"This Source Code may also be made available under the following
Secondary Licenses when the conditions for such availability set forth
in the Eclipse Public License, v. 2.0 are satisfied: {name license(s),
version(s), and exceptions or additional permissions here}."
Simply including a copy of this Agreement, including this Exhibit A
is not sufficient to license the Source Code under Secondary Licenses.
If it is not possible or desirable to put the notice in a particular
file, then You may include the notice in a location (such as a LICENSE
file in a relevant directory) where a recipient would be likely to
look for such a notice.
You may add additional accurate notices of copyright ownership.

`ClientOptions.KeepAlive` (sends regular messages to check the link is active).
* Brokers offer many configuration options; some settings may lead to unexpected results. If using Mosquitto check
`max_inflight_messages`, `max_queued_messages`, `persistence` (the defaults may not be what you expect).
`ClientOptions.KeepAlive` (sends regular messages to check the link is active).
* Reusing a `Client` is not completely safe. After calling `Disconnect` please create a new Client (`NewClient()`) rather
than attempting to reuse the existing one (note that features such as `SetAutoReconnect` mean this is rarely necessary).
* Brokers offer many configuration options; some settings may lead to unexpected results.
* Publish tokens will complete if the connection is lost and re-established using the default
options.SetAutoReconnect(true) functionality (token.Error() will return nil). Attempts will be made to re-deliver the
message but there is currently no easy way know when such messages are delivered.
If using Mosquitto then there are a range of fairly common issues:
* `listener` - By default [Mosquitto v2+](https://mosquitto.org/documentation/migrating-to-2-0/) listens on loopback
interfaces only (meaning it will only accept connections made from the computer its running on).
* `max_inflight_messages` - Unless this is set to 1 mosquitto does not guarantee ordered delivery of messages.
* `max_queued_messages` / `max_queued_bytes` - These impose limits on the number/size of queued messages. The defaults
may lead to messages being silently dropped.
* `persistence` - Defaults to false (messages will not survive a broker restart)
* `max_keepalive` - defaults to 65535 and, from version 2.0.12, `SetKeepAlive(0)` will result in a rejected connection
by default.
Reporting bugs
--------------
Please report bugs by raising issues for this project in github https://github.com/eclipse/paho.mqtt.golang/issues
*A limited number of contributors monitor the issues section so if you have a general question please consider the
resources in the [more information](#more-information) section (your question will be seen by more people, and you are
likely to receive an answer more quickly).*
A limited number of contributors monitor the issues section so if you have a general question please see the
resources in the [more information](#more-information) section for help.
We welcome bug reports, but it is important they are actionable. A significant percentage of issues reported are not
resolved due to a lack of information. If we cannot replicate the problem then it is unlikely we will be able to fix it.
The information required will vary from issue to issue but consider including:
The information required will vary from issue to issue but almost all bug reports would be expected to include:
* Which version of the package you are using (tag or commit - this should be in your go.mod file)
* A [Minimal, Reproducible Example](https://stackoverflow.com/help/minimal-reproducible-example). Providing an example
is the best way to demonstrate the issue you are facing; it is important this includes all relevant information
(including broker configuration). Docker (see `cmd/docker`) makes it relatively simple to provide a working end-to-end
example.
* Which version of the package you are using (tag or commit - this should be in your `go.mod` file)
* A full, clear, description of the problem (detail what you are expecting vs what actually happens).
* Configuration information (code showing how you connect, please include all references to `ClientOption`)
* Broker details (name and version).
If at all possible please also include:
* Details of your attempts to resolve the issue (what have you tried, what worked, what did not).
* [Application Logs](#logging) covering the period the issue occurred. Unless you have isolated the root cause of the issue please include a link to a full log (including data from well before the problem arose).
* Broker Logs covering the period the issue occurred.

Eclipse Public License - v 1.0
THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
1. DEFINITIONS
"Contribution" means:
a) in the case of the initial Contributor, the initial code and documentation distributed under this Agreement, and
b) in the case of each subsequent Contributor:
i) changes to the Program, and
ii) additions to the Program;
where such changes and/or additions to the Program originate from and are distributed by that particular Contributor. A Contribution 'originates' from a Contributor if it was added to the Program by such Contributor itself or anyone acting on such Contributor's behalf. Contributions do not include additions to the Program which: (i) are separate modules of software distributed in conjunction with the Program under their own license agreement, and (ii) are not derivative works of the Program.
"Contributor" means any person or entity that distributes the Program.
"Licensed Patents" mean patent claims licensable by a Contributor which are necessarily infringed by the use or sale of its Contribution alone or when combined with the Program.
"Program" means the Contributions distributed in accordance with this Agreement.
"Recipient" means anyone who receives the Program under this Agreement, including all Contributors.
2. GRANT OF RIGHTS
a) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, distribute and sublicense the Contribution of such Contributor, if any, and such derivative works, in source code and object code form.
b) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free patent license under Licensed Patents to make, use, sell, offer to sell, import and otherwise transfer the Contribution of such Contributor, if any, in source code and object code form. This patent license shall apply to the combination of the Contribution and the Program if, at the time the Contribution is added by the Contributor, such addition of the Contribution causes such combination to be covered by the Licensed Patents. The patent license shall not apply to any other combinations which include the Contribution. No hardware per se is licensed hereunder.
c) Recipient understands that although each Contributor grants the licenses to its Contributions set forth herein, no assurances are provided by any Contributor that the Program does not infringe the patent or other intellectual property rights of any other entity. Each Contributor disclaims any liability to Recipient for claims brought by any other entity based on infringement of intellectual property rights or otherwise. As a condition to exercising the rights and licenses granted hereunder, each Recipient hereby assumes sole responsibility to secure any other intellectual property rights needed, if any. For example, if a third party patent license is required to allow Recipient to distribute the Program, it is Recipient's responsibility to acquire that license before distributing the Program.
d) Each Contributor represents that to its knowledge it has sufficient copyright rights in its Contribution, if any, to grant the copyright license set forth in this Agreement.
3. REQUIREMENTS
A Contributor may choose to distribute the Program in object code form under its own license agreement, provided that:
a) it complies with the terms and conditions of this Agreement; and
b) its license agreement:
i) effectively disclaims on behalf of all Contributors all warranties and conditions, express and implied, including warranties or conditions of title and non-infringement, and implied warranties or conditions of merchantability and fitness for a particular purpose;
ii) effectively excludes on behalf of all Contributors all liability for damages, including direct, indirect, special, incidental and consequential damages, such as lost profits;
iii) states that any provisions which differ from this Agreement are offered by that Contributor alone and not by any other party; and
iv) states that source code for the Program is available from such Contributor, and informs licensees how to obtain it in a reasonable manner on or through a medium customarily used for software exchange.
When the Program is made available in source code form:
a) it must be made available under this Agreement; and
b) a copy of this Agreement must be included with each copy of the Program.
Contributors may not remove or alter any copyright notices contained within the Program.
Each Contributor must identify itself as the originator of its Contribution, if any, in a manner that reasonably allows subsequent Recipients to identify the originator of the Contribution.
4. COMMERCIAL DISTRIBUTION
Commercial distributors of software may accept certain responsibilities with respect to end users, business partners and the like. While this license is intended to facilitate the commercial use of the Program, the Contributor who includes the Program in a commercial product offering should do so in a manner which does not create potential liability for other Contributors. Therefore, if a Contributor includes the Program in a commercial product offering, such Contributor ("Commercial Contributor") hereby agrees to defend and indemnify every other Contributor ("Indemnified Contributor") against any losses, damages and costs (collectively "Losses") arising from claims, lawsuits and other legal actions brought by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such Commercial Contributor in connection with its distribution of the Program in a commercial product offering. The obligations in this section do not apply to any claims or Losses relating to any actual or alleged intellectual property infringement. In order to qualify, an Indemnified Contributor must: a) promptly notify the Commercial Contributor in writing of such claim, and b) allow the Commercial Contributor to control, and cooperate with the Commercial Contributor in, the defense and any related settlement negotiations. The Indemnified Contributor may participate in any such claim at its own expense.
For example, a Contributor might include the Program in a commercial product offering, Product X. That Contributor is then a Commercial Contributor. If that Commercial Contributor then makes performance claims, or offers warranties related to Product X, those performance claims and warranties are such Commercial Contributor's responsibility alone. Under this section, the Commercial Contributor would have to defend claims against the other Contributors related to those performance claims and warranties, and if a court requires any other Contributor to pay any damages as a result, the Commercial Contributor must pay those damages.
5. NO WARRANTY
EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED 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. Each Recipient is solely responsible for determining the appropriateness of using and distributing the Program and assumes all risks associated with its exercise of rights under this Agreement , including but not limited to the risks and costs of program errors, compliance with applicable laws, damage to or loss of data, programs or equipment, and unavailability or interruption of operations.
6. DISCLAIMER OF LIABILITY
EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
7. GENERAL
If any provision of this Agreement is invalid or unenforceable under applicable law, it shall not affect the validity or enforceability of the remainder of the terms of this Agreement, and without further action by the parties hereto, such provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable.
If Recipient institutes patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Program itself (excluding combinations of the Program with other software or hardware) infringes such Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate as of the date such litigation is filed.
All Recipient's rights under this Agreement shall terminate if it fails to comply with any of the material terms or conditions of this Agreement and does not cure such failure in a reasonable period of time after becoming aware of such noncompliance. If all Recipient's rights under this Agreement terminate, Recipient agrees to cease use and distribution of the Program as soon as reasonably practicable. However, Recipient's obligations under this Agreement and any licenses granted by Recipient relating to the Program shall continue and survive.
Everyone is permitted to copy and distribute copies of this Agreement, but in order to avoid inconsistency the Agreement is copyrighted and may only be modified in the following manner. The Agreement Steward reserves the right to publish new versions (including revisions) of this Agreement from time to time. No one other than the Agreement Steward has the right to modify this Agreement. The Eclipse Foundation is the initial Agreement Steward. The Eclipse Foundation may assign the responsibility to serve as the Agreement Steward to a suitable separate entity. Each new version of the Agreement will be given a distinguishing version number. The Program (including Contributions) may always be distributed subject to the version of the Agreement under which it was received. In addition, after a new version of the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the new version. Except as expressly stated in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or otherwise. All rights in the Program not expressly granted under this Agreement are reserved.
This Agreement is governed by the laws of the State of New York and the intellectual property laws of the United States of America. No party to this Agreement will bring a legal action under this Agreement more than one year after the cause of action arose. Each party waives its rights to a jury trial in any resulting litigation.

Version 2.0, or any later versions of that license, including any
exceptions or additional permissions as identified by the initial
Contributor.
2. GRANT OF RIGHTS
a) Subject to the terms of this Agreement, each Contributor hereby
grants Recipient a non-exclusive, worldwide, royalty-free copyright
license to reproduce, prepare Derivative Works of, publicly display,
publicly perform, Distribute and sublicense the Contribution of such
Contributor, if any, and such Derivative Works.
b) Subject to the terms of this Agreement, each Contributor hereby
grants Recipient a non-exclusive, worldwide, royalty-free patent
license under Licensed Patents to make, use, sell, offer to sell,
import and otherwise transfer the Contribution of such Contributor,
if any, in Source Code or other form. This patent license shall
apply to the combination of the Contribution and the Program if, at
the time the Contribution is added by the Contributor, such addition
of the Contribution causes such combination to be covered by the
Licensed Patents. The patent license shall not apply to any other
combinations which include the Contribution. No hardware per se is
licensed hereunder.
c) Recipient understands that although each Contributor grants the
licenses to its Contributions set forth herein, no assurances are
provided by any Contributor that the Program does not infringe the
patent or other intellectual property rights of any other entity.
Each Contributor disclaims any liability to Recipient for claims
brought by any other entity based on infringement of intellectual
property rights or otherwise. As a condition to exercising the
rights and licenses granted hereunder, each Recipient hereby
assumes sole responsibility to secure any other intellectual
property rights needed, if any. For example, if a third party
patent license is required to allow Recipient to Distribute the
Program, it is Recipient's responsibility to acquire that license
before distributing the Program.
d) Each Contributor represents that to its knowledge it has
sufficient copyright rights in its Contribution, if any, to grant
the copyright license set forth in this Agreement.
e) Notwithstanding the terms of any Secondary License, no
Contributor makes additional grants to any Recipient (other than
those set forth in this Agreement) as a result of such Recipient's
receipt of the Program under the terms of a Secondary License
(if permitted under the terms of Section 3).
3. REQUIREMENTS
3.1 If a Contributor Distributes the Program in any form, then:
a) the Program must also be made available as Source Code, in
accordance with section 3.2, and the Contributor must accompany
the Program with a statement that the Source Code for the Program
is available under this Agreement, and informs Recipients how to
obtain it in a reasonable manner on or through a medium customarily
used for software exchange; and
b) the Contributor may Distribute the Program under a license
different than this Agreement, provided that such license:
i) effectively disclaims on behalf of all other Contributors all
warranties and conditions, express and implied, including
warranties or conditions of title and non-infringement, and
implied warranties or conditions of merchantability and fitness
for a particular purpose;
ii) effectively excludes on behalf of all other Contributors all
liability for damages, including direct, indirect, special,
incidental and consequential damages, such as lost profits;
iii) does not attempt to limit or alter the recipients' rights
in the Source Code under section 3.2; and
iv) requires any subsequent distribution of the Program by any
party to be under a license that satisfies the requirements
of this section 3.
3.2 When the Program is Distributed as Source Code:
a) it must be made available under this Agreement, or if the
Program (i) is combined with other material in a separate file or
files made available under a Secondary License, and (ii) the initial
Contributor attached to the Source Code the notice described in
Exhibit A of this Agreement, then the Program may be made available
under the terms of such Secondary Licenses, and
b) a copy of this Agreement must be included with each copy of
the Program.
3.3 Contributors may not remove or alter any copyright, patent,
trademark, attribution notices, disclaimers of warranty, or limitations
of liability ("notices") contained within the Program from any copy of
the Program which they Distribute, provided that Contributors may add
their own appropriate notices.
4. COMMERCIAL DISTRIBUTION
Commercial distributors of software may accept certain responsibilities
with respect to end users, business partners and the like. While this
license is intended to facilitate the commercial use of the Program,
the Contributor who includes the Program in a commercial product
offering should do so in a manner which does not create potential
liability for other Contributors. Therefore, if a Contributor includes
the Program in a commercial product offering, such Contributor
("Commercial Contributor") hereby agrees to defend and indemnify every
other Contributor ("Indemnified Contributor") against any losses,
damages and costs (collectively "Losses") arising from claims, lawsuits
and other legal actions brought by a third party against the Indemnified
Contributor to the extent caused by the acts or omissions of such
Commercial Contributor in connection with its distribution of the Program
in a commercial product offering. The obligations in this section do not
apply to any claims or Losses relating to any actual or alleged
intellectual property infringement. In order to qualify, an Indemnified
Contributor must: a) promptly notify the Commercial Contributor in
writing of such claim, and b) allow the Commercial Contributor to control,
and cooperate with the Commercial Contributor in, the defense and any
related settlement negotiations. The Indemnified Contributor may
participate in any such claim at its own expense.
For example, a Contributor might include the Program in a commercial
product offering, Product X. That Contributor is then a Commercial
Contributor. If that Commercial Contributor then makes performance
claims, or offers warranties related to Product X, those performance
claims and warranties are such Commercial Contributor's responsibility
alone. Under this section, the Commercial Contributor would have to
defend claims against the other Contributors related to those performance
claims and warranties, and if a court requires any other Contributor to
pay any damages as a result, the Commercial Contributor must pay
those damages.
5. NO WARRANTY
EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
PERMITTED BY APPLICABLE LAW, THE PROGRAM IS PROVIDED 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. Each Recipient is solely responsible for determining the
appropriateness of using and distributing the Program and assumes all
risks associated with its exercise of rights under this Agreement,
including but not limited to the risks and costs of program errors,
compliance with applicable laws, damage to or loss of data, programs
or equipment, and unavailability or interruption of operations.
6. DISCLAIMER OF LIABILITY
EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
PERMITTED BY APPLICABLE LAW, NEITHER RECIPIENT NOR ANY CONTRIBUTORS
SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,
EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST
PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN
CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE)
ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE
EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
7. GENERAL
If any provision of this Agreement is invalid or unenforceable under
applicable law, it shall not affect the validity or enforceability of
the remainder of the terms of this Agreement, and without further
action by the parties hereto, such provision shall be reformed to the
minimum extent necessary to make such provision valid and enforceable.
If Recipient institutes patent litigation against any entity
(including a cross-claim or counterclaim in a lawsuit) alleging that the
Program itself (excluding combinations of the Program with other software
or hardware) infringes such Recipient's patent(s), then such Recipient's
rights granted under Section 2(b) shall terminate as of the date such
litigation is filed.
All Recipient's rights under this Agreement shall terminate if it
fails to comply with any of the material terms or conditions of this
Agreement and does not cure such failure in a reasonable period of
time after becoming aware of such noncompliance. If all Recipient's
rights under this Agreement terminate, Recipient agrees to cease use
and distribution of the Program as soon as reasonably practicable.
However, Recipient's obligations under this Agreement and any licenses
granted by Recipient relating to the Program shall continue and survive.
Everyone is permitted to copy and distribute copies of this Agreement,
but in order to avoid inconsistency the Agreement is copyrighted and
may only be modified in the following manner. The Agreement Steward
reserves the right to publish new versions (including revisions) of
this Agreement from time to time. No one other than the Agreement
Steward has the right to modify this Agreement. The Eclipse Foundation
is the initial Agreement Steward. The Eclipse Foundation may assign the
responsibility to serve as the Agreement Steward to a suitable separate
entity. Each new version of the Agreement will be given a distinguishing
version number. The Program (including Contributions) may always be
Distributed subject to the version of the Agreement under which it was
received. In addition, after a new version of the Agreement is published,
Contributor may elect to Distribute the Program (including its
Contributions) under the new version.
Except as expressly stated in Sections 2(a) and 2(b) above, Recipient
receives no rights or licenses to the intellectual property of any
Contributor under this Agreement, whether expressly, by implication,
estoppel or otherwise. All rights in the Program not expressly granted
under this Agreement are reserved. Nothing in this Agreement is intended
to be enforceable by any entity that is not a Contributor or Recipient.
No third-party beneficiary rights are created under this Agreement.
Exhibit A - Form of Secondary Licenses Notice
"This Source Code may also be made available under the following
Secondary Licenses when the conditions for such availability set forth
in the Eclipse Public License, v. 2.0 are satisfied: {name license(s),
version(s), and exceptions or additional permissions here}."
Simply including a copy of this Agreement, including this Exhibit A
is not sufficient to license the Source Code under Secondary Licenses.
If it is not possible or desirable to put the notice in a particular
file, then You may include the notice in a location (such as a LICENSE
file in a relevant directory) where a recipient would be likely to
look for such a notice.
You may add additional accurate notices of copyright ownership.

<h3>Applicable Licenses</h3>
<p>Unless otherwise indicated, all Content made available by the Eclipse Foundation is provided to you under the terms and conditions of the Eclipse Public License Version 1.0
(&quot;EPL&quot;). A copy of the EPL is provided with this Content and is also available at <a href="http://www.eclipse.org/legal/epl-v10.html">http://www.eclipse.org/legal/epl-v10.html</a>.
For purposes of the EPL, &quot;Program&quot; will mean the Content.</p>
<p>Content includes, but is not limited to, source code, object code, documentation and other files maintained in the Eclipse Foundation source code
repository (&quot;Repository&quot;) in software modules (&quot;Modules&quot;) and made available as downloadable archives (&quot;Downloads&quot;).</p>
<ul>
<li>Content may be structured and packaged into modules to facilitate delivering, extending, and upgrading the Content. Typical modules may include plug-ins (&quot;Plug-ins&quot;), plug-in fragments (&quot;Fragments&quot;), and features (&quot;Features&quot;).</li>
<li>Each Plug-in or Fragment may be packaged as a sub-directory or JAR (Java&trade; ARchive) in a directory named &quot;plugins&quot;.</li>
<li>A Feature is a bundle of one or more Plug-ins and/or Fragments and associated material. Each Feature may be packaged as a sub-directory in a directory named &quot;features&quot;. Within a Feature, files named &quot;feature.xml&quot; may contain a list of the names and version numbers of the Plug-ins
and/or Fragments associated with that Feature.</li>
<li>Features may also include other Features (&quot;Included Features&quot;). Within a Feature, files named &quot;feature.xml&quot; may contain a list of the names and version numbers of Included Features.</li>

# A minimal logging API for Go
[![Go Reference](https://pkg.go.dev/badge/github.com/go-logr/logr.svg)](https://pkg.go.dev/github.com/go-logr/logr)
logr offers an(other) opinion on how Go programs and libraries can do logging
without becoming coupled to a particular logging implementation. This is not
an implementation of logging - it is an API. In fact it is two APIs with two
different sets of users.
The `Logger` type is intended for application and library authors. It provides
a relatively small API which can be used everywhere you want to emit logs. It
defers the actual act of writing logs (to files, to stdout, or whatever) to the
`LogSink` interface.
The `LogSink` interface is intended for logging library implementers. It is a
pure interface which can be implemented by logging frameworks to provide the actual logging
functionality.
This decoupling allows application and library developers to write code in
terms of `logr.Logger` (which has very low dependency fan-out) while the
implementation of logging is managed "up stack" (e.g. in or near `main()`.)
Application developers can then switch out implementations as necessary.
Many people assert that libraries should not be logging, and as such efforts
like this are pointless. Those people are welcome to convince the authors of
the tens-of-thousands of libraries that *DO* write logs that they are all
wrong. In the meantime, logr takes a more practical approach.
## Typical usage
Somewhere, early in an application's life, it will make a decision about which
logging library (implementation) it actually wants to use. Something like:
```
func main() {
// ... other setup code ...
// Create the "root" logger. We have chosen the "logimpl" implementation,
// which takes some initial parameters and returns a logr.Logger.
logger := logimpl.New(param1, param2)
// ... other setup code ...
```
Most apps will call into other libraries, create structures to govern the flow,
etc. The `logr.Logger` object can be passed to these other libraries, stored
in structs, or even used as a package-global variable, if needed. For example:
```
app := createTheAppObject(logger)
app.Run()
```
Outside of this early setup, no other packages need to know about the choice of
implementation. They write logs in terms of the `logr.Logger` that they
received:
```
type appObject struct {
// ... other fields ...
logger logr.Logger
// ... other fields ...
}
func (app *appObject) Run() {
app.logger.Info("starting up", "timestamp", time.Now())
// ... app code ...
```
## Background
If the Go standard library had defined an interface for logging, this project
probably would not be needed. Alas, here we are.
### Inspiration
Before you consider this package, please read [this blog post by the
inimitable Dave Cheney][warning-makes-no-sense]. We really appreciate what
he has to say, and it largely aligns with our own experiences.
### Differences from Dave's ideas
The main differences are:
1. Dave basically proposes doing away with the notion of a logging API in favor
of `fmt.Printf()`. We disagree, especially when you consider things like output
locations, timestamps, file and line decorations, and structured logging. This
package restricts the logging API to just 2 types of logs: info and error.
Info logs are things you want to tell the user which are not errors. Error
logs are, well, errors. If your code receives an `error` from a subordinate
function call and is logging that `error` *and not returning it*, use error
logs.
2. Verbosity-levels on info logs. This gives developers a chance to indicate
arbitrary grades of importance for info logs, without assigning names with
semantic meaning such as "warning", "trace", and "debug." Superficially this
may feel very similar, but the primary difference is the lack of semantics.
Because verbosity is a numerical value, it's safe to assume that an app running
with higher verbosity means more (and less important) logs will be generated.
## Implementations (non-exhaustive)
There are implementations for the following logging libraries:
- **a function** (can bridge to non-structured libraries): [funcr](https://github.com/go-logr/logr/tree/master/funcr)
- **a testing.T** (for use in Go tests, with JSON-like output): [testr](https://github.com/go-logr/logr/tree/master/testr)
- **github.com/google/glog**: [glogr](https://github.com/go-logr/glogr)
- **k8s.io/klog** (for Kubernetes): [klogr](https://git.k8s.io/klog/klogr)
- **a testing.T** (with klog-like text output): [ktesting](https://git.k8s.io/klog/ktesting)
- **go.uber.org/zap**: [zapr](https://github.com/go-logr/zapr)
- **log** (the Go standard library logger): [stdr](https://github.com/go-logr/stdr)
- **github.com/sirupsen/logrus**: [logrusr](https://github.com/bombsimon/logrusr)
- **github.com/wojas/genericr**: [genericr](https://github.com/wojas/genericr) (makes it easy to implement your own backend)
- **logfmt** (Heroku style [logging](https://www.brandur.org/logfmt)): [logfmtr](https://github.com/iand/logfmtr)
- **github.com/rs/zerolog**: [zerologr](https://github.com/go-logr/zerologr)
- **github.com/go-kit/log**: [gokitlogr](https://github.com/tonglil/gokitlogr) (also compatible with github.com/go-kit/kit/log since v0.12.0)
- **bytes.Buffer** (writing to a buffer): [bufrlogr](https://github.com/tonglil/buflogr) (useful for ensuring values were logged, like during testing)
## FAQ
### Conceptual
#### Why structured logging?
- **Structured logs are more easily queryable**: Since you've got
key-value pairs, it's much easier to query your structured logs for
particular values by filtering on the contents of a particular key --
think searching request logs for error codes, Kubernetes reconcilers for
the name and namespace of the reconciled object, etc.
- **Structured logging makes it easier to have cross-referenceable logs**:
Similarly to searchability, if you maintain conventions around your
keys, it becomes easy to gather all log lines related to a particular
concept.
- **Structured logs allow better dimensions of filtering**: if you have
structure to your logs, you've got more precise control over how much
information is logged -- you might choose in a particular configuration
to log certain keys but not others, only log lines where a certain key
matches a certain value, etc., instead of just having v-levels and names
to key off of.
- **Structured logs better represent structured data**: sometimes, the
data that you want to log is inherently structured (think tuple-link
objects.) Structured logs allow you to preserve that structure when
outputting.
#### Why V-levels?
**V-levels give operators an easy way to control the chattiness of log
operations**. V-levels provide a way for a given package to distinguish
the relative importance or verbosity of a given log message. Then, if
a particular logger or package is logging too many messages, the user
of the package can simply change the v-levels for that library.
#### Why not named levels, like Info/Warning/Error?
Read [Dave Cheney's post][warning-makes-no-sense]. Then read [Differences
from Dave's ideas](#differences-from-daves-ideas).
#### Why not allow format strings, too?
**Format strings negate many of the benefits of structured logs**:
- They're not easily searchable without resorting to fuzzy searching,
regular expressions, etc.
- They don't store structured data well, since contents are flattened into
a string.
- They're not cross-referenceable.
- They don't compress easily, since the message is not constant.
(Unless you turn positional parameters into key-value pairs with numerical
keys, at which point you've gotten key-value logging with meaningless
keys.)
### Practical
#### Why key-value pairs, and not a map?
Key-value pairs are *much* easier to optimize, especially around
allocations. Zap (a structured logger that inspired logr's interface) has
[performance measurements](https://github.com/uber-go/zap#performance)
that show this quite nicely.
While the interface ends up being a little less obvious, you get
potentially better performance, plus avoid making users type
`map[string]string{}` every time they want to log.
#### What if my V-levels differ between libraries?
That's fine. Control your V-levels on a per-logger basis, and use the
`WithName` method to pass different loggers to different libraries.
Generally, you should take care to ensure that you have relatively
consistent V-levels within a given logger, however, as this makes deciding
on what verbosity of logs to request easier.
#### But I really want to use a format string!
That's not actually a question. Assuming your question is "how do
I convert my mental model of logging with format strings to logging with
constant messages":
1. Figure out what the error actually is, as you'd write in a TL;DR style,
and use that as a message.
2. For every place you'd write a format specifier, look to the word before
it, and add that as a key value pair.
For instance, consider the following examples (all taken from spots in the
Kubernetes codebase):
- `klog.V(4).Infof("Client is returning errors: code %v, error %v",
responseCode, err)` becomes `logger.Error(err, "client returned an
error", "code", responseCode)`
- `klog.V(4).Infof("Got a Retry-After %ds response for attempt %d to %v",
seconds, retries, url)` becomes `logger.V(4).Info("got a retry-after
response when requesting url", "attempt", retries, "after
seconds", seconds, "url", url)`
If you *really* must use a format string, use it in a key's value, and
call `fmt.Sprintf` yourself. For instance: `log.Printf("unable to
reflect over type %T")` becomes `logger.Info("unable to reflect over
type", "type", fmt.Sprintf("%T"))`. In general though, the cases where
this is necessary should be few and far between.
#### How do I choose my V-levels?
This is basically the only hard constraint: increase V-levels to denote
more verbose or more debug-y logs.
Otherwise, you can start out with `0` as "you always want to see this",
`1` as "common logging that you might *possibly* want to turn off", and
`10` as "I would like to performance-test your log collection stack."
Then gradually choose levels in between as you need them, working your way
down from 10 (for debug and trace style logs) and up from 1 (for chattier
info-type logs.)
#### How do I choose my keys?
Keys are fairly flexible, and can hold more or less any string
value. For best compatibility with implementations and consistency
with existing code in other projects, there are a few conventions you
should consider.
- Make your keys human-readable.
- Constant keys are generally a good idea.
- Be consistent across your codebase.
- Keys should naturally match parts of the message string.
- Use lower case for simple keys and
[lowerCamelCase](https://en.wiktionary.org/wiki/lowerCamelCase) for
more complex ones. Kubernetes is one example of a project that has
[adopted that
convention](https://github.com/kubernetes/community/blob/HEAD/contributors/devel/sig-instrumentation/migration-to-structured-logging.md#name-arguments).
While key names are mostly unrestricted (and spaces are acceptable),
it's generally a good idea to stick to printable ascii characters, or at
least match the general character set of your log lines.
#### Why should keys be constant values?
The point of structured logging is to make later log processing easier. Your
keys are, effectively, the schema of each log message. If you use different
keys across instances of the same log line, you will make your structured logs
much harder to use. `Sprintf()` is for values, not for keys!
#### Why is this not a pure interface?
The Logger type is implemented as a struct in order to allow the Go compiler to
optimize things like high-V `Info` logs that are not triggered. Not all of
these implementations are implemented yet, but this structure was suggested as
a way to ensure they *can* be implemented. All of the real work is behind the
`LogSink` interface.

// This design derives from Dave Cheney's blog:
// http://dave.cheney.net/2015/11/05/lets-talk-about-logging
// Package logr defines a general-purpose logging API and abstract interfaces
// to back that API. Packages in the Go ecosystem can depend on this package,
// while callers can implement logging with whatever backend is appropriate.
//
// Usage
//
// Logging is done using a Logger instance. Logger is a concrete type with
// methods, which defers the actual logging to a LogSink interface. The main
// methods of Logger are Info() and Error(). Arguments to Info() and Error()
// are key/value pairs rather than printf-style formatted strings, emphasizing
// "structured logging".
//
// With Go's standard log package, we might write:
// log.Printf("setting target value %s", targetValue)
//
// With logr's structured logging, we'd write:
// logger.Info("setting target", "value", targetValue)
//
// Errors are much the same. Instead of:
// log.Printf("failed to open the pod bay door for user %s: %v", user, err)
//
// We'd write:
// logger.Error(err, "failed to open the pod bay door", "user", user)
//
// Info() and Error() are very similar, but they are separate methods so that
// LogSink implementations can choose to do things like attach additional
// information (such as stack traces) on calls to Error(). Error() messages are
// always logged, regardless of the current verbosity. If there is no error
// instance available, passing nil is valid.
//
// Verbosity
//
// Often we want to log information only when the application in "verbose
// mode". To write log lines that are more verbose, Logger has a V() method.
// The higher the V-level of a log line, the less critical it is considered.
// Log-lines with V-levels that are not enabled (as per the LogSink) will not
// be written. Level V(0) is the default, and logger.V(0).Info() has the same
// meaning as logger.Info(). Negative V-levels have the same meaning as V(0).
// Error messages do not have a verbosity level and are always logged.
//
// Where we might have written:
// if flVerbose >= 2 {
// log.Printf("an unusual thing happened")
// }
//
// We can write:
// logger.V(2).Info("an unusual thing happened")
//
// Logger Names
//
// Logger instances can have name strings so that all messages logged through
// that instance have additional context. For example, you might want to add
// a subsystem name:
//
// logger.WithName("compactor").Info("started", "time", time.Now())
//
// The WithName() method returns a new Logger, which can be passed to
// constructors or other functions for further use. Repeated use of WithName()
// will accumulate name "segments". These name segments will be joined in some
// way by the LogSink implementation. It is strongly recommended that name
// segments contain simple identifiers (letters, digits, and hyphen), and do
// not contain characters that could muddle the log output or confuse the
// joining operation (e.g. whitespace, commas, periods, slashes, brackets,
// quotes, etc).
//
// Saved Values
//
// Logger instances can store any number of key/value pairs, which will be
// logged alongside all messages logged through that instance. For example,
// you might want to create a Logger instance per managed object:
//
// With the standard log package, we might write:
// log.Printf("decided to set field foo to value %q for object %s/%s",
// targetValue, object.Namespace, object.Name)
//
// With logr we'd write:
// // Elsewhere: set up the logger to log the object name.
// obj.logger = mainLogger.WithValues(
// "name", obj.name, "namespace", obj.namespace)
//
// // later on...
// obj.logger.Info("setting foo", "value", targetValue)
//
// Best Practices
//
// Logger has very few hard rules, with the goal that LogSink implementations
// might have a lot of freedom to differentiate. There are, however, some
// things to consider.
//
// The log message consists of a constant message attached to the log line.
// This should generally be a simple description of what's occurring, and should
// never be a format string. Variable information can then be attached using
// named values.
//
// Keys are arbitrary strings, but should generally be constant values. Values
// may be any Go value, but how the value is formatted is determined by the
// LogSink implementation.
//
// Logger instances are meant to be passed around by value. Code that receives
// such a value can call its methods without having to check whether the
// instance is ready for use.
//
// Calling methods with the null logger (Logger{}) as instance will crash
// because it has no LogSink. Therefore this null logger should never be passed
// around. For cases where passing a logger is optional, a pointer to Logger
// should be used.
//
// Key Naming Conventions
//
// Keys are not strictly required to conform to any specification or regex, but
// it is recommended that they:
// * be human-readable and meaningful (not auto-generated or simple ordinals)
// * be constant (not dependent on input data)
// * contain only printable characters
// * not contain whitespace or punctuation
// * use lower case for simple keys and lowerCamelCase for more complex ones
//
// These guidelines help ensure that log data is processed properly regardless
// of the log implementation. For example, log implementations will try to
// output JSON data or will store data for later database (e.g. SQL) queries.
//
// While users are generally free to use key names of their choice, it's
// generally best to avoid using the following keys, as they're frequently used
// by implementations:
// * "caller": the calling information (file/line) of a particular log line
// * "error": the underlying error value in the `Error` method
// * "level": the log level
// * "logger": the name of the associated logger
// * "msg": the log message
// * "stacktrace": the stack trace associated with a particular log line or
// error (often from the `Error` message)
// * "ts": the timestamp for a log line
//
// Implementations are encouraged to make use of these keys to represent the
// above concepts, when necessary (for example, in a pure-JSON output form, it
// would be necessary to represent at least message and timestamp as ordinary
// named values).
//
// Break Glass
//
// Implementations may choose to give callers access to the underlying
// logging implementation. The recommended pattern for this is:
// // Underlier exposes access to the underlying logging implementation.
// // Since callers only have a logr.Logger, they have to know which
// // implementation is in use, so this interface is less of an abstraction
// // and more of way to test type conversion.
// type Underlier interface {
// GetUnderlying() <underlying-type>
// }
//
// Logger grants access to the sink to enable type assertions like this:
// func DoSomethingWithImpl(log logr.Logger) {
// if underlier, ok := log.GetSink()(impl.Underlier) {
// implLogger := underlier.GetUnderlying()
// ...
// }
// }
//
// Custom `With*` functions can be implemented by copying the complete
// Logger struct and replacing the sink in the copy:
// // WithFooBar changes the foobar parameter in the log sink and returns a
// // new logger with that modified sink. It does nothing for loggers where
// // the sink doesn't support that parameter.
// func WithFoobar(log logr.Logger, foobar int) logr.Logger {
// if foobarLogSink, ok := log.GetSink()(FoobarSink); ok {
// log = log.WithSink(foobarLogSink.WithFooBar(foobar))
// }
// return log
// }
//
// Don't use New to construct a new Logger with a LogSink retrieved from an
// existing Logger. Source code attribution might not work correctly and
// unexported fields in Logger get lost.
//
// Beware that the same LogSink instance may be shared by different logger
// instances. Calling functions that modify the LogSink will affect all of
// those.

## [Unreleased]
## [1.7.0/0.30.0] - 2022-04-28
### Added
- Add the `go.opentelemetry.io/otel/semconv/v1.8.0` package.
The package contains semantic conventions from the `v1.8.0` version of the OpenTelemetry specification. (#2763)
- Add the `go.opentelemetry.io/otel/semconv/v1.9.0` package.
The package contains semantic conventions from the `v1.9.0` version of the OpenTelemetry specification. (#2792)
- Add the `go.opentelemetry.io/otel/semconv/v1.10.0` package.
The package contains semantic conventions from the `v1.10.0` version of the OpenTelemetry specification. (#2842)
- Added an in-memory exporter to metrictest to aid testing with a full SDK. (#2776)
### Fixed
- Globally delegated instruments are unwrapped before delegating asynchronous callbacks. (#2784)
- Remove import of `testing` package in non-tests builds of the `go.opentelemetry.io/otel` package. (#2786)
### Changed
- The `WithLabelEncoder` option from the `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` package is renamed to `WithAttributeEncoder`. (#2790)
- The `LabelFilterSelector` interface from `go.opentelemetry.io/otel/sdk/metric/processor/reducer` is renamed to `AttributeFilterSelector`.
The method included in the renamed interface also changed from `LabelFilterFor` to `AttributeFilterFor`. (#2790)
- The `Metadata.Labels` method from the `go.opentelemetry.io/otel/sdk/metric/export` package is renamed to `Metadata.Attributes`.
Consequentially, the `Record` type from the same package also has had the embedded method renamed. (#2790)
### Deprecated
- The `Iterator.Label` method in the `go.opentelemetry.io/otel/attribute` package is deprecated.
Use the equivalent `Iterator.Attribute` method instead. (#2790)
- The `Iterator.IndexedLabel` method in the `go.opentelemetry.io/otel/attribute` package is deprecated.
Use the equivalent `Iterator.IndexedAttribute` method instead. (#2790)
- The `MergeIterator.Label` method in the `go.opentelemetry.io/otel/attribute` package is deprecated.
Use the equivalent `MergeIterator.Attribute` method instead. (#2790)
### Removed
- Removed the `Batch` type from the `go.opentelemetry.io/otel/sdk/metric/metrictest` package. (#2864)
- Removed the `Measurement` type from the `go.opentelemetry.io/otel/sdk/metric/metrictest` package. (#2864)
## [0.29.0] - 2022-04-11
### Added
- The metrics global package was added back into several test files. (#2764)
- The `Meter` function is added back to the `go.opentelemetry.io/otel/metric/global` package.
This function is a convenience function equivalent to calling `global.MeterProvider().Meter(...)`. (#2750)
### Removed
- Removed module the `go.opentelemetry.io/otel/sdk/export/metric`.
Use the `go.opentelemetry.io/otel/sdk/metric` module instead. (#2720)
### Changed
- Don't panic anymore when setting a global MeterProvider to itself. (#2749)
- Upgrade `go.opentelemetry.io/proto/otlp` in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric` from `v0.12.1` to `v0.15.0`.
This replaces the use of the now deprecated `InstrumentationLibrary` and `InstrumentationLibraryMetrics` types and fields in the proto library with the equivalent `InstrumentationScope` and `ScopeMetrics`. (#2748)
## [1.6.3] - 2022-04-07
### Fixed
- Allow non-comparable global `MeterProvider`, `TracerProvider`, and `TextMapPropagator` types to be set. (#2772, #2773)
## [1.6.2] - 2022-04-06
### Changed
- Don't panic anymore when setting a global TracerProvider or TextMapPropagator to itself. (#2749)
- Upgrade `go.opentelemetry.io/proto/otlp` in `go.opentelemetry.io/otel/exporters/otlp/otlptrace` from `v0.12.1` to `v0.15.0`.
This replaces the use of the now deprecated `InstrumentationLibrary` and `InstrumentationLibrarySpans` types and fields in the proto library with the equivalent `InstrumentationScope` and `ScopeSpans`. (#2748)
## [1.6.1] - 2022-03-28
### Fixed
- The `go.opentelemetry.io/otel/schema/*` packages now use the correct schema URL for their `SchemaURL` constant.
Instead of using `"https://opentelemetry.io/schemas/v<version>"` they now use the correct URL without a `v` prefix, `"https://opentelemetry.io/schemas/<version>"`. (#2743, #2744)
### Security
- Upgrade `go.opentelemetry.io/proto/otlp` from `v0.12.0` to `v0.12.1`.
This includes an indirect upgrade of `github.com/grpc-ecosystem/grpc-gateway` which resolves [a vulnerability](https://nvd.nist.gov/vuln/detail/CVE-2019-11254) from `gopkg.in/yaml.v2` in version `v2.2.3`. (#2724, #2728)
## [1.6.0/0.28.0] - 2022-03-23
### ⚠️ Notice ⚠️
This update is a breaking change of the unstable Metrics API.
Code instrumented with the `go.opentelemetry.io/otel/metric` will need to be modified.
### Added
- Add metrics exponential histogram support.
New mapping functions have been made available in `sdk/metric/aggregator/exponential/mapping` for other OpenTelemetry projects to take dependencies on. (#2502)
- Add Go 1.18 to our compatibility tests. (#2679)
- Allow configuring the Sampler with the `OTEL_TRACES_SAMPLER` and `OTEL_TRACES_SAMPLER_ARG` environment variables. (#2305, #2517)
- Add the `metric/global` for obtaining and setting the global `MeterProvider`. (#2660)
### Changed
- The metrics API has been significantly changed to match the revised OpenTelemetry specification.
High-level changes include:
- Synchronous and asynchronous instruments are now handled by independent `InstrumentProvider`s.
These `InstrumentProvider`s are managed with a `Meter`.
- Synchronous and asynchronous instruments are grouped into their own packages based on value types.
- Asynchronous callbacks can now be registered with a `Meter`.
Be sure to check out the metric module documentation for more information on how to use the revised API. (#2587, #2660)
### Fixed
- Fallback to general attribute limits when span specific ones are not set in the environment. (#2675, #2677)
## [1.5.0] - 2022-03-16
### Added
- Log the Exporters configuration in the TracerProviders message. (#2578)
- Added support to configure the span limits with environment variables.
The following environment variables are supported. (#2606, #2637)
- `OTEL_SPAN_ATTRIBUTE_VALUE_LENGTH_LIMIT`
- `OTEL_SPAN_ATTRIBUTE_COUNT_LIMIT`
- `OTEL_SPAN_EVENT_COUNT_LIMIT`
- `OTEL_EVENT_ATTRIBUTE_COUNT_LIMIT`
- `OTEL_SPAN_LINK_COUNT_LIMIT`
- `OTEL_LINK_ATTRIBUTE_COUNT_LIMIT`
If the provided environment variables are invalid (negative), the default values would be used.
- Rename the `gc` runtime name to `go` (#2560)
- Add resource container ID detection. (#2418)
- Add span attribute value length limit.
The new `AttributeValueLengthLimit` field is added to the `"go.opentelemetry.io/otel/sdk/trace".SpanLimits` type to configure this limit for a `TracerProvider`.
The default limit for this resource is "unlimited". (#2637)
- Add the `WithRawSpanLimits` option to `go.opentelemetry.io/otel/sdk/trace`.
This option replaces the `WithSpanLimits` option.
Zero or negative values will not be changed to the default value like `WithSpanLimits` does.
Setting a limit to zero will effectively disable the related resource it limits and setting to a negative value will mean that resource is unlimited.
Consequentially, limits should be constructed using `NewSpanLimits` and updated accordingly. (#2637)
### Changed
- Drop oldest tracestate `Member` when capacity is reached. (#2592)
- Add event and link drop counts to the exported data from the `oltptrace` exporter. (#2601)
- Unify path cleaning functionally in the `otlpmetric` and `otlptrace` configuration. (#2639)
- Change the debug message from the `sdk/trace.BatchSpanProcessor` to reflect the count is cumulative. (#2640)
- Introduce new internal `envconfig` package for OTLP exporters. (#2608)
- If `http.Request.Host` is empty, fall back to use `URL.Host` when populating `http.host` in the `semconv` packages. (#2661)
### Fixed
- Remove the OTLP trace exporter limit of SpanEvents when exporting. (#2616)
- Default to port `4318` instead of `4317` for the `otlpmetrichttp` and `otlptracehttp` client. (#2614, #2625)
- Unlimited span limits are now supported (negative values). (#2636, #2637)
### Deprecated
- Deprecated `"go.opentelemetry.io/otel/sdk/trace".WithSpanLimits`.
Use `WithRawSpanLimits` instead.
That option allows setting unlimited and zero limits, this option does not.
This option will be kept until the next major version incremented release. (#2637)
## [1.4.1] - 2022-02-16
### Fixed
- Fix race condition in reading the dropped spans number for the `BatchSpanProcessor`. (#2615)
## [1.4.0] - 2022-02-11
### Added
- Use `OTEL_EXPORTER_ZIPKIN_ENDPOINT` environment variable to specify zipkin collector endpoint. (#2490)
- Log the configuration of `TracerProvider`s, and `Tracer`s for debugging.
To enable use a logger with Verbosity (V level) `>=1`. (#2500)
- Added support to configure the batch span-processor with environment variables.
The following environment variables are used. (#2515)
- `OTEL_BSP_SCHEDULE_DELAY`
- `OTEL_BSP_EXPORT_TIMEOUT`
- `OTEL_BSP_MAX_QUEUE_SIZE`.
- `OTEL_BSP_MAX_EXPORT_BATCH_SIZE`
### Changed
- Zipkin exporter exports `Resource` attributes in the `Tags` field. (#2589)
### Deprecated
- Deprecate module the `go.opentelemetry.io/otel/sdk/export/metric`.
Use the `go.opentelemetry.io/otel/sdk/metric` module instead. (#2382)
- Deprecate `"go.opentelemetry.io/otel/sdk/metric".AtomicFieldOffsets`. (#2445)
### Fixed
- Fixed the instrument kind for noop async instruments to correctly report an implementation. (#2461)
- Fix UDP packets overflowing with Jaeger payloads. (#2489, #2512)
- Change the `otlpmetric.Client` interface's `UploadMetrics` method to accept a single `ResourceMetrics` instead of a slice of them. (#2491)
- Specify explicit buckets in Prometheus example, fixing issue where example only has `+inf` bucket. (#2419, #2493)
- W3C baggage will now decode urlescaped values. (#2529)
- Baggage members are now only validated once, when calling `NewMember` and not also when adding it to the baggage itself. (#2522)
- The order attributes are dropped from spans in the `go.opentelemetry.io/otel/sdk/trace` package when capacity is reached is fixed to be in compliance with the OpenTelemetry specification.
Instead of dropping the least-recently-used attribute, the last added attribute is dropped.
This drop order still only applies to attributes with unique keys not already contained in the span.
If an attribute is added with a key already contained in the span, that attribute is updated to the new value being added. (#2576)
### Removed
- Updated `go.opentelemetry.io/proto/otlp` from `v0.11.0` to `v0.12.0`. This version removes a number of deprecated methods. (#2546)
- [`Metric.GetIntGauge()`](https://pkg.go.dev/go.opentelemetry.io/proto/otlp@v0.11.0/metrics/v1#Metric.GetIntGauge)
- [`Metric.GetIntHistogram()`](https://pkg.go.dev/go.opentelemetry.io/proto/otlp@v0.11.0/metrics/v1#Metric.GetIntHistogram)
- [`Metric.GetIntSum()`](https://pkg.go.dev/go.opentelemetry.io/proto/otlp@v0.11.0/metrics/v1#Metric.GetIntSum)
## [1.3.0] - 2021-12-10
### ⚠️ Notice ⚠️
We have updated the project minimum supported Go version to 1.16
### Added
- Added an internal Logger.
This can be used by the SDK and API to provide users with feedback of the internal state.
To enable verbose logs configure the logger which will print V(1) logs. For debugging information configure to print V(5) logs. (#2343)
- Add the `WithRetry` `Option` and the `RetryConfig` type to the `go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetrichttp` package to specify retry behavior consistently. (#2425)
- Add `SpanStatusFromHTTPStatusCodeAndSpanKind` to all `semconv` packages to return a span status code similar to `SpanStatusFromHTTPStatusCode`, but exclude `4XX` HTTP errors as span errors if the span is of server kind. (#2296)
### Changed
- The `"go.opentelemetry.io/otel/exporter/otel/otlptrace/otlptracegrpc".Client` now uses the underlying gRPC `ClientConn` to handle name resolution, TCP connection establishment (with retries and backoff) and TLS handshakes, and handling errors on established connections by re-resolving the name and reconnecting. (#2329)
- The `"go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetricgrpc".Client` now uses the underlying gRPC `ClientConn` to handle name resolution, TCP connection establishment (with retries and backoff) and TLS handshakes, and handling errors on established connections by re-resolving the name and reconnecting. (#2425)
- The `"go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetricgrpc".RetrySettings` type is renamed to `RetryConfig`. (#2425)
- The `go.opentelemetry.io/otel/exporter/otel/*` gRPC exporters now default to using the host's root CA set if none are provided by the user and `WithInsecure` is not specified. (#2432)
- Change `resource.Default` to be evaluated the first time it is called, rather than on import. This allows the caller the option to update `OTEL_RESOURCE_ATTRIBUTES` first, such as with `os.Setenv`. (#2371)
### Fixed
- The `go.opentelemetry.io/otel/exporter/otel/*` exporters are updated to handle per-signal and universal endpoints according to the OpenTelemetry specification.
Any per-signal endpoint set via an `OTEL_EXPORTER_OTLP_<signal>_ENDPOINT` environment variable is now used without modification of the path.
When `OTEL_EXPORTER_OTLP_ENDPOINT` is set, if it contains a path, that path is used as a base path which per-signal paths are appended to. (#2433)
- Basic metric controller updated to use sync.Map to avoid blocking calls (#2381)
- The `go.opentelemetry.io/otel/exporter/jaeger` correctly sets the `otel.status_code` value to be a string of `ERROR` or `OK` instead of an integer code. (#2439, #2440)
### Deprecated
- Deprecated the `"go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetrichttp".WithMaxAttempts` `Option`, use the new `WithRetry` `Option` instead. (#2425)
- Deprecated the `"go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetrichttp".WithBackoff` `Option`, use the new `WithRetry` `Option` instead. (#2425)
### Removed
- Remove the metric Processor's ability to convert cumulative to delta aggregation temporality. (#2350)
- Remove the metric Bound Instruments interface and implementations. (#2399)
- Remove the metric MinMaxSumCount kind aggregation and the corresponding OTLP export path. (#2423)
- Metric SDK removes the "exact" aggregator for histogram instruments, as it performed a non-standard aggregation for OTLP export (creating repeated Gauge points) and worked its way into a number of confusing examples. (#2348)
## [1.2.0] - 2021-11-12
## Changed
### Changed
- Metric SDK `export.ExportKind`, `export.ExportKindSelector` types have been renamed to `aggregation.Temporality` and `aggregation.TemporalitySelector` respectively to keep in line with current specification and protocol along with built-in selectors (e.g., `aggregation.CumulativeTemporalitySelector`, ...). (#2274)
- The Metric `Exporter` interface now requires a `TemporalitySelector` method instead of an `ExportKindSelector`. (#2274)
@ -24,7 +279,7 @@ This project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.htm
- Add the `"go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc".WithGRPCConn` option so the exporter can reuse an existing gRPC connection. (#2002)
- Added a new `schema` module to help parse Schema Files in OTEP 0152 format. (#2267)
- Added a new `MapCarrier` to the `go.opentelemetry.io/otel/propagation` package to hold propagated coss-cutting concerns as a `map[string]string` held in memory. (#2334)

### Compatibility
OpenTelemetry-Go attempts to track the current supported versions of the
[Go language](https://golang.org/doc/devel/release#policy). The release
schedule after a new minor version of go is as follows:
- The first release or one month, which ever is sooner, will add build steps for the new go version.
- The first release after three months will remove support for the oldest go version.
This project is tested on the following systems.

While this project should work for other systems, no compatibility guarantees
are made for those systems currently.
Go 1.18 was added in March of 2022.
Go 1.16 will be removed around June 2022.

## Semantic Convention Generation
If a new version of the OpenTelemetry Specification has been released it will be necessary to generate a new
semantic convention package from the YAML definitions in the specification repository. There is a `semconvgen` utility
installed by `make tools` that can be used to generate the a package with the name matching the specification
version number under the `semconv` package. This will ideally be done soon after the specification release is
tagged. Make sure that the specification repo contains a checkout of the the latest tagged release so that the
generated files match the released semantic conventions.
New versions of the [OpenTelemetry specification] mean new versions of the `semconv` package need to be generated.
The `semconv-generate` make target is used for this.
There are currently two categories of semantic conventions that must be generated, `resource` and `trace`.
1. Checkout a local copy of the [OpenTelemetry specification] to the desired release tag.
2. Run the `make semconv-generate ...` target from this repository.
```
.tools/semconvgen -i /path/to/specification/repo/semantic_conventions/resource -t semconv/template.j2
.tools/semconvgen -i /path/to/specification/repo/semantic_conventions/trace -t semconv/template.j2
For example,
```sh
export TAG="v1.7.0" # Change to the release version you are generating.
export OTEL_SPEC_REPO="/absolute/path/to/opentelemetry-specification"
git -C "$OTEL_SPEC_REPO" checkout "tags/$TAG"
make semconv-generate # Uses the exported TAG and OTEL_SPEC_REPO.
```
Using default values for all options other than `input` will result in using the `template.j2` template to
generate `resource.go` and `trace.go` in `/path/to/otelgo/repo/semconv/<version>`.
There are several ancillary files that are not generated and should be copied into the new package from the
prior package, with updates made as appropriate to canonical import path statements and constant values.
These files include:
* doc.go
* exception.go
* http(_test)?.go
* schema.go
Uses of the previous schema version in this repository should be updated to use the newly generated version.
No tooling for this exists at present, so use find/replace in your editor of choice or craft a `grep | sed`
pipeline if you like living on the edge.
This should create a new sub-package of [`semconv`](./semconv).
Ensure things look correct before submitting a pull request to include the addition.

This package is currently in a pre-GA phase. Backwards incompatible changes
may be introduced in subsequent minor version releases as we work to track the
evolving OpenTelemetry specification and user feedback.
Measurements can be made about an operation being performed or the state of a
system in general. These measurements can be crucial to the reliable operation
of code and provide valuable insights about the inner workings of a system.
Measurements are made using instruments provided by this package. The type of
instrument used will depend on the type of measurement being made and of what
part of a system is being measured.
Instruments are categorized as Synchronous or Asynchronous and independently
as Adding or Grouping. Synchronous instruments are called by the user with a
Context. Asynchronous instruments are called by the SDK during collection.
Adding instruments are semantically intended for capturing a sum. Grouping
instruments are intended for capturing a distribution.
Adding instruments may be monotonic, in which case they are non-decreasing
and naturally define a rate.
The synchronous instrument names are:
Counter: adding, monotonic
UpDownCounter: adding
Histogram: grouping
and the asynchronous instruments are:
CounterObserver: adding, monotonic
UpDownCounterObserver: adding
GaugeObserver: grouping
All instruments are provided with support for either float64 or int64 input
values.
An instrument is created using a Meter. Additionally, a Meter is used to
record batches of synchronous measurements or asynchronous observations. A
Meter is obtained using a MeterProvider. A Meter, like a Tracer, is unique to
the instrumentation it instruments and must be named and versioned when
created with a MeterProvider with the name and version of the instrumentation
library.
Instrumentation should be designed to accept a MeterProvider from which it can
create its own unique Meter. Alternatively, the registered global
MeterProvider from the go.opentelemetry.io/otel package can be used as a
default.
