The interpretation of +// binary messages is left to the application. +// +// This package uses the TextMessage and BinaryMessage integer constants to +// identify the two data message types. The ReadMessage and NextReader methods +// return the type of the received message. The messageType argument to the +// WriteMessage and NextWriter methods specifies the type of a sent message. +// +// It is the application's responsibility to ensure that text messages are +// valid UTF-8 encoded text. +// +// Control Messages +// +// The WebSocket protocol defines three types of control messages: close, ping +// and pong. Call the connection WriteControl, WriteMessage or NextWriter +// methods to send a control message to the peer. +// +// Connections handle received close messages by calling the handler function +// set with the SetCloseHandler method and by returning a *CloseError from the +// NextReader, ReadMessage or the message Read method. The default close +// handler sends a close message to the peer. +// +// Connections handle received ping messages by calling the handler function +// set with the SetPingHandler method. The default ping handler sends a pong +// message to the peer. +// +// Connections handle received pong messages by calling the handler function +// set with the SetPongHandler method. The default pong handler does nothing. +// If an application sends ping messages, then the application should set a +// pong handler to receive the corresponding pong. +// +// The control message handler functions are called from the NextReader, +// ReadMessage and message reader Read methods. The default close and ping +// handlers can block these methods for a short time when the handler writes to +// the connection. +// +// The application must read the connection to process close, ping and pong +// messages sent from the peer. If the application is not otherwise interested +// in messages from the peer, then the application should start a goroutine to +// read and discard messages from the peer. A simple example is: +// +// func readLoop(c *websocket.Conn) { +// for { +// if _, _, err := c.NextReader(); err != nil { +// c.Close() +// break +// } +// } +// } +// +// Concurrency +// +// Connections support one concurrent reader and one concurrent writer. +// +// Applications are responsible for ensuring that no more than one goroutine +// calls the write methods (NextWriter, SetWriteDeadline, WriteMessage, +// WriteJSON, EnableWriteCompression, SetCompressionLevel) concurrently and +// that no more than one goroutine calls the read methods (NextReader, +// SetReadDeadline, ReadMessage, ReadJSON, SetPongHandler, SetPingHandler) +// concurrently. +// +// The Close and WriteControl methods can be called concurrently with all other +// methods. +// +// Origin Considerations +// +// Web browsers allow Javascript applications to open a WebSocket connection to +// any host. It's up to the server to enforce an origin policy using the Origin +// request header sent by the browser. +// +// The Upgrader calls the function specified in the CheckOrigin field to check +// the origin. If the CheckOrigin function returns false, then the Upgrade +// method fails the WebSocket handshake with HTTP status 403. +// +// If the CheckOrigin field is nil, then the Upgrader uses a safe default: fail +// the handshake if the Origin request header is present and the Origin host is +// not equal to the Host request header. +// +// The deprecated package-level Upgrade function does not perform origin +// checking.

(Don't include + the brackets!) The text should be enclosed in the appropriate + comment syntax for the file format. We also recommend that a + file or class name and description of purpose be included on the + same "printed page" as the copyright notice for easier + identification within third-party archives. + + Copyright [yyyy] [name of copyright owner] + + Licensed under the Apache License, Version 2.0 (the "License"); + you may not use this file except in compliance with the License. + You may obtain a copy of the License at + + http://www.apache.org/licenses/LICENSE-2.0 + + Unless required by applicable law or agreed to in writing, software + distributed under the License is distributed on an "AS IS" BASIS, + WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + See the License for the specific language governing permissions and + limitations under the License. + +------------------------------------------------------------------------------ + +The software is released under the terms of the GNU Affero General Public +License, version 3. + + GNU AFFERO GENERAL PUBLIC LICENSE + Version 3, 19 November 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The GNU Affero General Public License is a free, copyleft license for +software and other kinds of works, specifically designed to ensure +cooperation with the community in the case of network server software. + + The licenses for most software and other practical works are designed +to take away your freedom to share and change the works. By contrast, +our General Public Licenses are intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + Developers that use our General Public Licenses protect your rights +with two steps: (1) assert copyright on the software, and (2) offer +you this License which gives you legal permission to copy, distribute +and/or modify the software. + + A secondary benefit of defending all users' freedom is that +improvements made in alternate versions of the program, if they +receive widespread use, become available for other developers to +incorporate. Many developers of free software are heartened and +encouraged by the resulting cooperation. However, in the case of +software used on network servers, this result may fail to come about. +The GNU General Public License permits making a modified version and +letting the public access it on a server without ever releasing its +source code to the public. + + The GNU Affero General Public License is designed specifically to +ensure that, in such cases, the modified source code becomes available +to the community. It requires the operator of a network server to +provide the source code of the modified version running there to the +users of that server. Therefore, public use of a modified version, on +a publicly accessible server, gives the public access to the source +code of the modified version. + + An older license, called the Affero General Public License and +published by Affero, was designed to accomplish similar goals. This is +a different license, not a version of the Affero GPL, but Affero has +released a new version of the Affero GPL which permits relicensing under +this license. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU Affero General 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. 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. + + 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 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 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. Remote Network Interaction; Use with the GNU General Public License. + + Notwithstanding any other provision of this License, if you modify the +Program, your modified version must prominently offer all users +interacting with it remotely through a computer network (if your version +supports such interaction) an opportunity to receive the Corresponding +Source of your version by providing access to the Corresponding Source +from a network server at no charge, through some standard or customary +means of facilitating copying of software. This Corresponding Source +shall include the Corresponding Source for any work covered by version 3 +of the GNU General Public License that is incorporated pursuant to the +following paragraph. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the work with which it is combined will remain governed by version +3 of the GNU General Public License. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU Affero General Public License from time to time. Such new versions +will be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU Affero General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU Affero General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU Affero General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU Affero General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU Affero General Public License for more details. + + You should have received a copy of the GNU Affero General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If your software can interact with users remotely through a computer +network, you should also make sure that it provides a way for users to +get its source. For example, if your program is a web application, its +interface could display a "Source" link that leads users to an archive +of the code. There are many ways you could offer source, and different +solutions will be better for different programs; see section 13 for the +specific requirements. + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU AGPL, see +. diff --git a/build/manifest/vendor/github.com/mattermost/mattermost-server/NOTICE.txt b/build/manifest/vendor/github.com/mattermost/mattermost-server/NOTICE.txt new file mode 100644 index 000000000..87c144e25 --- /dev/null +++ b/build/manifest/vendor/github.com/mattermost/mattermost-server/NOTICE.txt @@ -0,0 +1,2723 @@ +Mattermost Server +© 2015-present Mattermost, Inc.

"Executable Form" + means any form of the work other than Source Code Form. + +1.7. "Larger Work" + means a work that combines Covered Software with other material, in + a separate file or files, that is not Covered Software. + +1.8. "License" + means this document. + +1.9.

"Patent Claims" of a Contributor + means any patent claim(s), including without limitation, method, + process, and apparatus claims, in any patent Licensable by such + Contributor that would be infringed, but for the grant of the + License, by the making, using, selling, offering for sale, having + made, import, or transfer of either its Contributions or its + Contributor Version. + +1.12. "Secondary License" + means either the GNU General Public License, Version 2.0, the GNU + Lesser General Public License, Version 2.1, the GNU Affero General + Public License, Version 3.0, or any later versions of those + licenses. + +1.13.

License Grants and Conditions +-------------------------------- + +2.1. Grants + +Each Contributor hereby grants You a world-wide, royalty-free, +non-exclusive license: + +(a) under intellectual property rights (other than patent or trademark) + Licensable by such Contributor to use, reproduce, make available, + modify, display, perform, distribute, and otherwise exploit its + Contributions, either on an unmodified basis, with Modifications, or + as part of a Larger Work; and + +(b) under Patent Claims of such Contributor to make, use, sell, offer + for sale, have made, import, and otherwise transfer either its + Contributions or its Contributor Version. + +2.2. Effective Date + +The licenses granted in Section 2.1 with respect to any Contribution +become effective for each Contribution on the date the Contributor first +distributes such Contribution. + +2.3. Limitations on Grant Scope + +The licenses granted in this Section 2 are the only rights granted under +this License. No additional rights or licenses will be implied from the +distribution or licensing of Covered Software under this License. +Notwithstanding Section 2.1(b) above, no patent license is granted by a +Contributor: + +(a) for any code that a Contributor has removed from Covered Software; + or + +(b) for infringements caused by: (i) Your and any other third party's + modifications of Covered Software, or (ii) the combination of its + Contributions with other software (except as part of its Contributor + Version); or + +(c) under Patent Claims infringed by Covered Software in the absence of + its Contributions. + +This License does not grant any rights in the trademarks, service marks, +or logos of any Contributor (except as may be necessary to comply with +the notice requirements in Section 3.4). + +2.4. Subsequent Licenses + +No Contributor makes additional grants as a result of Your choice to +distribute the Covered Software under a subsequent version of this +License (see Section 10.2) or under the terms of a Secondary License (if +permitted under the terms of Section 3.3). + +2.5. Representation + +Each Contributor represents that the Contributor believes its +Contributions are its original creation(s) or it has sufficient rights +to grant the rights to its Contributions conveyed by this License. + +2.6. Fair Use + +This License is not intended to limit any rights You have under +applicable copyright doctrines of fair use, fair dealing, or other +equivalents. + +2.7. Conditions + +Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted +in Section 2.1. + +3. Responsibilities +------------------- + +3.1. Distribution of Source Form + +All distribution of Covered Software in Source Code Form, including any +Modifications that You create or to which You contribute, must be under +the terms of this License. You must inform recipients that the Source +Code Form of the Covered Software is governed by the terms of this +License, and how they can obtain a copy of this License. You may not +attempt to alter or restrict the recipients' rights in the Source Code +Form. + +3.2. Distribution of Executable Form + +If You distribute Covered Software in Executable Form then: + +(a) such Covered Software must also be made available in Source Code + Form, as described in Section 3.1, and You must inform recipients of + the Executable Form how they can obtain a copy of such Source Code + Form by reasonable means in a timely manner, at a charge no more + than the cost of distribution to the recipient; and + +(b) You may distribute such Executable Form under the terms of this + License, or sublicense it under different terms, provided that the + license for the Executable Form does not attempt to limit or alter + the recipients' rights in the Source Code Form under this License. + +3.3. Distribution of a Larger Work + +You may create and distribute a Larger Work under terms of Your choice, +provided that You also comply with the requirements of this License for +the Covered Software. If the Larger Work is a combination of Covered +Software with a work governed by one or more Secondary Licenses, and the +Covered Software is not Incompatible With Secondary Licenses, this +License permits You to additionally distribute such Covered Software +under the terms of such Secondary License(s), so that the recipient of +the Larger Work may, at their option, further distribute the Covered +Software under the terms of either this License or such Secondary +License(s). + +3.4. Notices + +You may not remove or alter the substance of any license notices +(including copyright notices, patent notices, disclaimers of warranty, +or limitations of liability) contained within the Source Code Form of +the Covered Software, except that You may alter any license notices to +the extent required to remedy known factual inaccuracies. + +3.5. Application of Additional Terms + +You may choose to offer, and to charge a fee for, warranty, support, +indemnity or liability obligations to one or more recipients of Covered +Software. However, You may do so only on Your own behalf, and not on +behalf of any Contributor. You must make it absolutely clear that any +such warranty, support, indemnity, or liability obligation is offered by +You alone, and You hereby agree to indemnify every Contributor for any +liability incurred by such Contributor as a result of warranty, support, +indemnity or liability terms You offer. You may include additional +disclaimers of warranty and limitations of liability specific to any +jurisdiction. + +4. Inability to Comply Due to Statute or Regulation +--------------------------------------------------- + +If it is impossible for You to comply with any of the terms of this +License with respect to some or all of the Covered Software due to +statute, judicial order, or regulation then You must: (a) comply with +the terms of this License to the maximum extent possible; and (b) +describe the limitations and the code they affect. Such description must +be placed in a text file included with all distributions of the Covered +Software under this License. Except to the extent prohibited by statute +or regulation, such description must be sufficiently detailed for a +recipient of ordinary skill to be able to understand it. + +5. Termination +-------------- + +5.1. The rights granted under this License will terminate automatically +if You fail to comply with any of its terms. However, if You become +compliant, then the rights granted under this License from a particular +Contributor are reinstated (a) provisionally, unless and until such +Contributor explicitly and finally terminates Your grants, and (b) on an +ongoing basis, if such Contributor fails to notify You of the +non-compliance by some reasonable means prior to 60 days after You have +come back into compliance. Moreover, Your grants from a particular +Contributor are reinstated on an ongoing basis if such Contributor +notifies You of the non-compliance by some reasonable means, this is the +first time You have received notice of non-compliance with this License +from such Contributor, and You become compliant prior to 30 days after +Your receipt of the notice. + +5.2. If You initiate litigation against any entity by asserting a patent +infringement claim (excluding declaratory judgment actions, +counter-claims, and cross-claims) alleging that a Contributor Version +directly or indirectly infringes any patent, then the rights granted to +You by any and all Contributors for the Covered Software under Section +2.1 of this License shall terminate. + +5.3. In the event of termination under Sections 5.1 or 5.2 above, all +end user license agreements (excluding distributors and resellers) which +have been validly granted by You or Your distributors under this License +prior to termination shall survive termination. + +************************************************************************ +* * +* 6.

If you modify this Library, you +may apply this exception to your version of this Library, but you are not +obliged to do so. If you do not wish to do so, delete this exception +statement from your version. This exception does not (and cannot) modify any +license terms which apply to the Application, with which you must still +comply. + + + GNU LESSER GENERAL PUBLIC LICENSE + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + + This version of the GNU Lesser General Public License incorporates +the terms and conditions of version 3 of the GNU General Public +License, supplemented by the additional permissions listed below. + + 0. Additional Definitions. + + As used herein, "this License" refers to version 3 of the GNU Lesser +General Public License, and the "GNU GPL" refers to version 3 of the GNU +General Public License. + + "The Library" refers to a covered work governed by this License, +other than an Application or a Combined Work as defined below. + + An "Application" is any work that makes use of an interface provided +by the Library, but which is not otherwise based on the Library. +Defining a subclass of a class defined by the Library is deemed a mode +of using an interface provided by the Library. + + A "Combined Work" is a work produced by combining or linking an +Application with the Library. The particular version of the Library +with which the Combined Work was made is also called the "Linked +Version". + + The "Minimal Corresponding Source" for a Combined Work means the +Corresponding Source for the Combined Work, excluding any source code +for portions of the Combined Work that, considered in isolation, are +based on the Application, and not on the Linked Version. + + The "Corresponding Application Code" for a Combined Work means the +object code and/or source code for the Application, including any data +and utility programs needed for reproducing the Combined Work from the +Application, but excluding the System Libraries of the Combined Work. + + 1. Exception to Section 3 of the GNU GPL. + + You may convey a covered work under sections 3 and 4 of this License +without being bound by section 3 of the GNU GPL. + + 2. Conveying Modified Versions. + + If you modify a copy of the Library, and, in your modifications, a +facility refers to a function or data to be supplied by an Application +that uses the facility (other than as an argument passed when the +facility is invoked), then you may convey a copy of the modified +version: + + a) under this License, provided that you make a good faith effort to + ensure that, in the event an Application does not supply the + function or data, the facility still operates, and performs + whatever part of its purpose remains meaningful, or + + b) under the GNU GPL, with none of the additional permissions of + this License applicable to that copy. + + 3. Object Code Incorporating Material from Library Header Files. + + The object code form of an Application may incorporate material from +a header file that is part of the Library. You may convey such object +code under terms of your choice, provided that, if the incorporated +material is not limited to numerical parameters, data structure +layouts and accessors, or small macros, inline functions and templates +(ten or fewer lines in length), you do both of the following: + + a) Give prominent notice with each copy of the object code that the + Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the object code with a copy of the GNU GPL and this license + document. + + 4. Combined Works. + + You may convey a Combined Work under terms of your choice that, +taken together, effectively do not restrict modification of the +portions of the Library contained in the Combined Work and reverse +engineering for debugging such modifications, if you also do each of +the following: + + a) Give prominent notice with each copy of the Combined Work that + the Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the Combined Work with a copy of the GNU GPL and this license + document. + + c) For a Combined Work that displays copyright notices during + execution, include the copyright notice for the Library among + these notices, as well as a reference directing the user to the + copies of the GNU GPL and this license document. + + d) Do one of the following: + + 0) Convey the Minimal Corresponding Source under the terms of this + License, and the Corresponding Application Code in a form + suitable for, and under terms that permit, the user to + recombine or relink the Application with a modified version of + the Linked Version to produce a modified Combined Work, in the + manner specified by section 6 of the GNU GPL for conveying + Corresponding Source. + + 1) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (a) uses at run time + a copy of the Library already present on the user's computer + system, and (b) will operate properly with a modified version + of the Library that is interface-compatible with the Linked + Version. + + e) Provide Installation Information, but only if you would otherwise + be required to provide such information under section 6 of the + GNU GPL, and only to the extent that such information is + necessary to install and execute a modified version of the + Combined Work produced by recombining or relinking the + Application with a modified version of the Linked Version. (If + you use option 4d0, the Installation Information must accompany + the Minimal Corresponding Source and Corresponding Application + Code. If you use option 4d1, you must provide the Installation + Information in the manner specified by section 6 of the GNU GPL + for conveying Corresponding Source.) + + 5. Combined Libraries. + + You may place library facilities that are a work based on the +Library side by side in a single library together with other library +facilities that are not Applications and are not covered by this +License, and convey such a combined library under terms of your +choice, if you do both of the following: + + a) Accompany the combined library with a copy of the same work based + on the Library, uncombined with any other library facilities, + conveyed under the terms of this License. + + b) Give prominent notice with the combined library that part of it + is a work based on the Library, and explaining where to find the + accompanying uncombined form of the same work. + + 6. Revised Versions of the GNU Lesser General Public License. + + The Free Software Foundation may publish revised and/or new versions +of the GNU Lesser General Public License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. + + Each version is given a distinguishing version number. If the +Library as you received it specifies that a certain numbered version +of the GNU Lesser General Public License "or any later version" +applies to it, you have the option of following the terms and +conditions either of that published version or of any later version +published by the Free Software Foundation. If the Library as you +received it does not specify a version number of the GNU Lesser +General Public License, you may choose any version of the GNU Lesser +General Public License ever published by the Free Software Foundation. + + If the Library as you received it specifies that a proxy can decide +whether future versions of the GNU Lesser General Public License shall +apply, that proxy's public statement of acceptance of any version is +permanent authorization for you to choose that version for the +Library. + +--- + +## throttled + +This product contains a modified portion of 'throttled', a package throttled implementing different throttling strategies for controlling access to HTTP handlers by Martin Angers and Contributors. + +* HOMEPAGE: + * https://github.com/throttled/throttled/tree/v1.0.0 + +* LICENSE: + +Copyright (c) 2014, Martin Angers and Contributors. +All rights reserved. + +Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: + +* 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 author nor the names of its contributors may be used to endorse or promote products derived from this software without specific prior written permission. + +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.

However, if You become compliant, + then the rights granted under this License from a particular Contributor + are reinstated (a) provisionally, unless and until such Contributor + explicitly and finally terminates Your grants, and (b) on an ongoing basis, + if such Contributor fails to notify You of the non-compliance by some + reasonable means prior to 60 days after You have come back into compliance. + Moreover, Your grants from a particular Contributor are reinstated on an + ongoing basis if such Contributor notifies You of the non-compliance by + some reasonable means, this is the first time You have received notice of + non-compliance with this License from such Contributor, and You become + compliant prior to 30 days after Your receipt of the notice. + +5.2. If You initiate litigation against any entity by asserting a patent + infringement claim (excluding declaratory judgment actions, counter-claims, + and cross-claims) alleging that a Contributor Version directly or + indirectly infringes any patent, then the rights granted to You by any and + all Contributors for the Covered Software under Section 2.1 of this License + shall terminate. + +5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user + license agreements (excluding distributors and resellers) which have been + validly granted by You or Your distributors under this License prior to + termination shall survive termination. + +6. Disclaimer of Warranty + + Covered Software is provided under this License on an “as is” basis, without + warranty of any kind, either expressed, implied, or statutory, including, + without limitation, warranties that the Covered Software is free of defects, + merchantable, fit for a particular purpose or non-infringing. The entire + risk as to the quality and performance of the Covered Software is with You. + Should any Covered Software prove defective in any respect, You (not any + Contributor) assume the cost of any necessary servicing, repair, or + correction. This disclaimer of warranty constitutes an essential part of this + License. No use of any Covered Software is authorized under this License + except under this disclaimer. + +7. Limitation of Liability + + Under no circumstances and under no legal theory, whether tort (including + negligence), contract, or otherwise, shall any Contributor, or anyone who + distributes Covered Software as permitted above, be liable to You for any + direct, indirect, special, incidental, or consequential damages of any + character including, without limitation, damages for lost profits, loss of + goodwill, work stoppage, computer failure or malfunction, or any and all + other commercial damages or losses, even if such party shall have been + informed of the possibility of such damages. This limitation of liability + shall not apply to liability for death or personal injury resulting from such + party’s negligence to the extent applicable law prohibits such limitation. + Some jurisdictions do not allow the exclusion or limitation of incidental or + consequential damages, so this exclusion and limitation may not apply to You. + +8. Litigation + + Any litigation relating to this License may be brought only in the courts of + a jurisdiction where the defendant maintains its principal place of business + and such litigation shall be governed by laws of that jurisdiction, without + reference to its conflict-of-law provisions. Nothing in this Section shall + prevent a party’s ability to bring cross-claims or counter-claims. + +9. Miscellaneous + + This License represents the complete agreement concerning the subject matter + hereof. If any provision of this License is held to be unenforceable, such + provision shall be reformed only to the extent necessary to make it + enforceable. Any law or regulation which provides that the language of a + contract shall be construed against the drafter shall not be used to construe + this License against a Contributor. + + +10. Versions of the License + +10.1. New Versions + + Mozilla Foundation is the license steward. Except as provided in Section + 10.3, no one other than the license steward has the right to modify or + publish new versions of this License. Each version will be given a + distinguishing version number. + +10.2. Effect of New Versions + + You may distribute the Covered Software under the terms of the version of + the License under which You originally received the Covered Software, or + under the terms of any subsequent version published by the license + steward. + +10.3. Modified Versions + + If you create software not governed by this License, and you want to + create a new license for such software, you may create and use a modified + version of this License if you rename the license and remove any + references to the name of the license steward (except to note that such + modified license differs from this License). + +10.4.

The license + affects thus the FreeType font engine, the test programs, + documentation and makefiles, at the very least. + + This license was inspired by the BSD, Artistic, and IJG + (Independent JPEG Group) licenses, which all encourage inclusion + and use of free software in commercial and freeware products + alike. As a consequence, its main points are that: + + o We don't promise that this software works. However, we will be + interested in any kind of bug reports. (`as is' distribution) + + o You can use this software for whatever you want, in parts or + full form, without having to pay us. (`royalty-free' usage) + + o You may not pretend that you wrote this software. If you use + it, or only parts of it, in a program, you must acknowledge + somewhere in your documentation that you have used the + FreeType code. (`credits') + + We specifically permit and encourage the inclusion of this + software, with or without modifications, in commercial products. + We disclaim all warranties covering The FreeType Project and + assume no liability related to The FreeType Project. + + + Finally, many people asked us for a preferred form for a + credit/disclaimer to use in compliance with this license. We thus + encourage you to use the following text: + + """ + Portions of this software are copyright � The FreeType + Project (www.freetype.org). All rights reserved. + """ + + Please replace with the value from the FreeType version you + actually use. + + +Legal Terms +=========== + +0. Definitions +-------------- + + Throughout this license, the terms `package', `FreeType Project', + and `FreeType archive' refer to the set of files originally + distributed by the authors (David Turner, Robert Wilhelm, and + Werner Lemberg) as the `FreeType Project', be they named as alpha, + beta or final release. + + `You' refers to the licensee, or person using the project, where + `using' is a generic term including compiling the project's source + code as well as linking it to form a `program' or `executable'. + This program is referred to as `a program using the FreeType + engine'. + + This license applies to all files distributed in the original + FreeType Project, including all source code, binaries and + documentation, unless otherwise stated in the file in its + original, unmodified form as distributed in the original archive. + If you are unsure whether or not a particular file is covered by + this license, you must contact us to verify this. + + The FreeType Project is copyright (C) 1996-2000 by David Turner, + Robert Wilhelm, and Werner Lemberg. All rights reserved except as + specified below. + +1. No Warranty +-------------- + + THE FREETYPE PROJECT IS PROVIDED `AS IS' WITHOUT WARRANTY OF ANY + KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, + WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR + PURPOSE. IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS + BE LIABLE FOR ANY DAMAGES CAUSED BY THE USE OR THE INABILITY TO + USE, OF THE FREETYPE PROJECT. + +2. Redistribution +----------------- + + This license grants a worldwide, royalty-free, perpetual and + irrevocable right and license to use, execute, perform, compile, + display, copy, create derivative works of, distribute and + sublicense the FreeType Project (in both source and object code + forms) and derivative works thereof for any purpose; and to + authorize others to exercise some or all of the rights granted + herein, subject to the following conditions: + + o Redistribution of source code must retain this license file + (`FTL.TXT') unaltered; any additions, deletions or changes to + the original files must be clearly indicated in accompanying + documentation. The copyright notices of the unaltered, + original files must be preserved in all copies of source + files. + + o Redistribution in binary form must provide a disclaimer that + states that the software is based in part of the work of the + FreeType Team, in the distribution documentation. We also + encourage you to put an URL to the FreeType web page in your + documentation, though this isn't mandatory. + + These conditions apply to any software derived from or based on + the FreeType Project, not just the unmodified files. If you use + our work, you must acknowledge us. However, no fee need be paid + to us. + +3. Advertising +-------------- + + Neither the FreeType authors and contributors nor you shall use + the name of the other for commercial, advertising, or promotional + purposes without specific prior written permission. + + We suggest, but do not require, that you use one or more of the + following phrases to refer to this software in your documentation + or advertising materials: `FreeType Project', `FreeType Engine', + `FreeType library', or `FreeType Distribution'. + + As you have not signed this license, you are not required to + accept it. However, as the FreeType Project is copyrighted + material, only this license, or another one contracted with the + authors, grants you the right to use, distribute, and modify it. + Therefore, by using, distributing, or modifying the FreeType + Project, you indicate that you understand and accept all the terms + of this license. + +4. Contacts +----------- + + There are two mailing lists related to FreeType: + + o freetype@nongnu.org + + Discusses general use and applications of FreeType, as well as + future and wanted additions to the library and distribution. + If you are looking for support, start in this list if you + haven't found anything to help you in the documentation. + + o freetype-devel@nongnu.org + + Discusses bugs, as well as engine internals, design issues, + specific licenses, porting, etc. + + Our home page can be found at + + http://www.freetype.org + +--- end of FTL.TXT --- diff --git a/build/manifest/vendor/github.com/mattermost/mattermost-server/app/license.go b/build/manifest/vendor/github.com/mattermost/mattermost-server/app/license.go new file mode 100644 index 000000000..310a61fdb --- /dev/null +++ b/build/manifest/vendor/github.com/mattermost/mattermost-server/app/license.go @@ -0,0 +1,219 @@ +// Copyright (c) 2017-present Mattermost, Inc.

+# go-toml
+
+Go library for the [TOML](https://github.com/mojombo/toml) format.
+
+This library supports TOML version
+[v0.4.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.4.0.md)
+
+[![GoDoc](https://godoc.org/github.com/pelletier/go-toml?status.svg)](http://godoc.org/github.com/pelletier/go-toml)
+[![license](https://img.shields.io/github/license/pelletier/go-toml.svg)](https://github.com/pelletier/go-toml/blob/master/LICENSE)
+[![Build Status](https://travis-ci.org/pelletier/go-toml.svg?branch=master)](https://travis-ci.org/pelletier/go-toml)
+[![Coverage Status](https://coveralls.io/repos/github/pelletier/go-toml/badge.svg?branch=master)](https://coveralls.io/github/pelletier/go-toml?branch=master)
+[![Go Report Card](https://goreportcard.com/badge/github.com/pelletier/go-toml)](https://goreportcard.com/report/github.com/pelletier/go-toml)
+
+## Features
+
+Go-toml provides the following features for using data parsed from TOML documents:
+
+* Load TOML documents from files and string data
+* Easily navigate TOML structure using Tree
+* Mashaling and unmarshaling to and from data structures
+* Line & column position data for all parsed elements
+* [Query support similar to JSON-Path](query/)
+* Syntax errors contain line and column numbers
+
+## Import
+
+```go
+import "github.com/pelletier/go-toml"
+```
+
+## Usage example
+
+Read a TOML document:
+
+```go
+config, _ := toml.Load(`
+[postgres]
+user = "pelletier"
+password = "mypassword"`)
+// retrieve data directly
+user := config.Get("postgres.user").(string)
+
+// or using an intermediate object
+postgresConfig := config.Get("postgres").(*toml.Tree)
+password := postgresConfig.Get("password").(string)
+```
+
+Or use Unmarshal:
+
+```go
+type Postgres struct {
+    User     string
+    Password string
+}
+type Config struct {
+    Postgres Postgres
+}
+
+doc := []byte(`
+[Postgres]
+User = "pelletier"
+Password = "mypassword"`)
+
+config := Config{}
+toml.Unmarshal(doc, &config)
+fmt.Println("user=", config.Postgres.User)
+```
+
+Or use a query:
+
+```go
+// use a query to gather elements without walking the tree
+q, _ := query.Compile("$..[user,password]")
+results := q.Execute(config)
+for ii, item := range results.Values() {
+    fmt.Println("Query result %d: %v", ii, item)
+}
+```
+
+## Documentation
+
+The documentation and additional examples are available at
+[godoc.org](http://godoc.org/github.com/pelletier/go-toml).
+
+## Tools
+
+Go-toml provides two handy command line tools:
+
+* `tomll`: Reads TOML files and lint them.
+
+    ```
+    go install github.com/pelletier/go-toml/cmd/tomll
+    tomll --help
+    ```
+* `tomljson`: Reads a TOML file and outputs its JSON representation.
+
+    ```
+    go install github.com/pelletier/go-toml/cmd/tomljson
+    tomljson --help
+    ```
+
+## Contribute
+
+Feel free to report bugs and patches using GitHub's pull requests system on
+[pelletier/go-toml](https://github.com/pelletier/go-toml). Any feedback would be
+much appreciated!
+
+### Run tests
+
+You have to make sure two kind of tests run:
+
+1. The Go unit tests
+2. The TOML examples base
+
+You can run both of them using `./test.sh`.
+
+### Fuzzing
+
+The script `./fuzz.sh` is available to
+run [go-fuzz](https://github.com/dvyukov/go-fuzz) on go-toml.
+

+// Package toml is a TOML parser and manipulation library.
+//
+// This version supports the specification as described in
+// https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.4.0.md
+//
+// Marshaling
+//
+// Go-toml can marshal and unmarshal TOML documents from and to data
+// structures.
+//
+// TOML document as a tree
+//
+// Go-toml can operate on a TOML document as a tree. Use one of the Load*
+// functions to parse TOML data and obtain a Tree instance, then one of its
+// methods to manipulate the tree.
+//
+// JSONPath-like queries
+//
+// The package github.com/pelletier/go-toml/query implements a system
+// similar to JSONPath to quickly retrieve elements of a TOML document using a
+// single expression. See the package documentation for more information.
+//

+
+Package errors provides simple error handling primitives.
+
+`go get github.com/pkg/errors`
+
+The traditional error handling idiom in Go is roughly akin to
+```go
+if err != nil {
+        return err
+}
+```
+which applied recursively up the call stack results in error reports without context or debugging information. The errors package allows programmers to add context to the failure path in their code in a way that does not destroy the original value of the error.
+
+## Adding context to an error
+
+The errors.Wrap function returns a new error that adds context to the original error. For example
+```go
+_, err := ioutil.ReadAll(r)
+if err != nil {
+        return errors.Wrap(err, "read failed")
+}
+```
+## Retrieving the cause of an error
+
+Using `errors.Wrap` constructs a stack of errors, adding context to the preceding error. Depending on the nature of the error it may be necessary to reverse the operation of errors.Wrap to retrieve the original error for inspection. Any error value which implements this interface can be inspected by `errors.Cause`.
+```go
+type causer interface {
+        Cause() error
+}
+```
+`errors.Cause` will recursively retrieve the topmost error which does not implement `causer`, which is assumed to be the original cause. For example:
+```go
+switch err := errors.Cause(err).(type) {
+case *MyError:
+        // handle specifically
+default:
+        // unknown error
+}
+```
+
+[Read the package documentation for more information](https://godoc.org/github.com/pkg/errors).

+# atomic [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov] [![Go Report Card][reportcard-img]][reportcard]
+
+Simple wrappers for primitive types to enforce atomic access.
+
+## Installation
+`go get -u go.uber.org/atomic`
+
+## Usage
+The standard library's `sync/atomic` is powerful, but it's easy to forget which
+variables must be accessed atomically. `go.uber.org/atomic` preserves all the
+functionality of the standard library, but wraps the primitive types to
+provide a safer, more convenient API.
+
+```go
+var atom atomic.Uint32
+atom.Store(42)
+atom.Sub(2)
+atom.CAS(40, 11)
+```
+
+See the [documentation][doc] for a complete API specification.
+
+## Development Status
+Stable.

+Releases
+========
+
+v1.1.0 (2017-06-30)
+===================

+// 	multierr.Combine(
+// 		reader.Close(),
+// 		writer.Close(),
+// 		conn.Close(),
+// 	)
+//
+// If only two errors are being combined, the Append function may be used
+// instead.
+//
+// 	err = multierr.Combine(reader.Close(), writer.Close())

+// This makes it possible to record resource cleanup failures from deferred
+// blocks with the help of named return values.

+// 		if err != nil {
+// 			return err
+// 		}
+// 		defer func() {
+// 			err = multierr.Append(err, conn.Close())
+// 		}()
+// 		// ...
+// 	}
+//
+// The underlying list of errors for a returned error object may be retrieved
+// with the Errors function.
+//
+// 	errors := multierr.Errors(err)
+// 	if len(errors) > 0 {
+// 		fmt.Println("The following errors occurred:")
+// 	}

+// Advanced Usage
+//
+// Errors returned by Combine and Append MAY implement the following
+// interface.
+//
+// 	type errorGroup interface {
+// 		// Returns a slice containing the underlying list of errors.
+// 		//
+// 		// This slice MUST NOT be modified by the caller.
+// 		Errors() []error
+// 	}
+//
+// Note that if you need access to list of errors behind a multierr error, you
+// should prefer using the Errors function. That said, if you need cheap
+// read-only access to the underlying errors slice, you can attempt to cast
+// the error to this interface. You MUST handle the failure case gracefully
+// because errors returned by Combine and Append are not guaranteed to
+// implement this interface.

+# :zap: zap [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov]
+
+Blazing fast, structured, leveled logging in Go.
+
+## Installation
+
+`go get -u go.uber.org/zap`
+
+Note that zap only supports the two most recent minor versions of Go.
+
+## Quick Start
+
+In contexts where performance is nice, but not critical, use the
+`SugaredLogger`. It's 4-10x faster than other structured logging
+packages and includes both structured and `printf`-style APIs.
+
+```go
+logger, _ := zap.NewProduction()
+defer logger.Sync() // flushes buffer, if any
+sugar := logger.Sugar()
+sugar.Infow("failed to fetch URL",
+  // Structured context as loosely typed key-value pairs.
+  "url", url,
+  "attempt", 3,
+  "backoff", time.Second,
+)
+sugar.Infof("Failed to fetch URL: %s", url)
+```
+
+When performance and type safety are critical, use the `Logger`. It's even
+faster than the `SugaredLogger` and allocates far less, but it only supports
+structured logging.
+
+```go
+logger, _ := zap.NewProduction()
+defer logger.Sync()
+logger.Info("failed to fetch URL",
+  // Structured context as strongly typed Field values.
+  zap.String("url", url),
+  zap.Int("attempt", 3),
+  zap.Duration("backoff", time.Second),
+)
+```
+
+See the [documentation][doc] and [FAQ](FAQ.md) for more details.
+
+## Performance
+
+For applications that log in the hot path, reflection-based serialization and
+string formatting are prohibitively expensive — they're CPU-intensive
+and make many small allocations. Put differently, using `encoding/json` and
+`fmt.Fprintf` to log tons of `interface{}`s makes your application slow.
+
+Zap takes a different approach. It includes a reflection-free, zero-allocation
+JSON encoder, and the base `Logger` strives to avoid serialization overhead
+and allocations wherever possible. By building the high-level `SugaredLogger`
+on that foundation, zap lets users *choose* when they need to count every
+allocation and when they'd prefer a more familiar, loosely typed API.
+
+As measured by its own [benchmarking suite][], not only is zap more performant
+than comparable structured logging packages — it's also faster than the
+standard library. Like all benchmarks, take these with a grain of salt.[1](#footnote-versions)
+
+Log a message and 10 fields:
+
+{{.BenchmarkAddingFields}}
+
+Log a message with a logger that already has 10 fields of context:
+
+{{.BenchmarkAccumulatedContext}}
+
+Log a static string, without any context or `printf`-style templating:
+
+{{.BenchmarkWithoutFields}}
+
+## Development Status: Stable
+
+All APIs are finalized, and no breaking changes will be made in the 1.x series
+of releases. Users of semver-aware dependency management systems should pin
+zap to `^1`.
+
+## Contributing
+
+We encourage and support an active, healthy community of contributors —
+including you! Details are in the [contribution guide](CONTRIBUTING.md) and
+the [code of conduct](CODE_OF_CONDUCT.md). The zap maintainers keep an eye on
+issues and pull requests, but you can also report any negative conduct to
+oss-conduct@uber.com. That email list is a private, safe space; even the zap
+maintainers don't have access, so don't hesitate to hold us to a high
+standard.

+It is fully backward-compatible.
+
+Bugfixes:
+
+* [#385][]: Fix caller path trimming on Windows.
+* [#396][]: Fix a panic when attempting to use non-existent directories with
+  zap's configuration struct.
+
+Enhancements:
+
+* [#386][]: Add filtering helpers to zaptest's observing logger.
+
+Thanks to @moitias for contributing to this release.
+
+## v1.0.0 (14 Mar 2017)
+
+This is zap's first stable release. All exported APIs are now final, and no
+further breaking changes will be made in the 1.x release series. Anyone using a
+semver-aware dependency manager should now pin to `^1`.
+
+Breaking changes:
+
+* [#366][]: Add byte-oriented APIs to encoders to log UTF-8 encoded text without
+  casting from `[]byte` to `string`.
+* [#364][]: To support buffering outputs, add `Sync` methods to `zapcore.Core`,
+  `zap.Logger`, and `zap.SugaredLogger`.
+* [#371][]: Rename the `testutils` package to `zaptest`, which is less likely to
+  clash with other testing helpers.
+
+Bugfixes:
+
+* [#362][]: Make the ISO8601 time formatters fixed-width, which is friendlier
+  for tab-separated console output.
+* [#369][]: Remove the automatic locks in `zapcore.NewCore`, which allows zap to
+  work with concurrency-safe `WriteSyncer` implementations.
+* [#347][]: Stop reporting errors when trying to `fsync` standard out on Linux
+  systems.
+* [#373][]: Report the correct caller from zap's standard library
+  interoperability wrappers.
+
+Enhancements:
+
+* [#348][]: Add a registry allowing third-party encodings to work with zap's
+  built-in `Config`.
+* [#327][]: Make the representation of logger callers configurable (like times,
+  levels, and durations).
+* [#376][]: Allow third-party encoders to use their own buffer pools, which
+  removes the last performance advantage that zap's encoders have over plugins.
+* [#346][]: Add `CombineWriteSyncers`, a convenience function to tee multiple
+  `WriteSyncer`s and lock the result.
+* [#365][]: Make zap's stacktraces compatible with mid-stack inlining (coming in
+  Go 1.9).
+* [#372][]: Export zap's observing logger as `zaptest/observer`. This makes it
+  easier for particularly punctilious users to unit test their application's
+  logging.
+
+Thanks to @suyash, @htrendev, @flisky, @Ulexus, and @skipor for their
+contributions to this release.
+
+## v1.0.0-rc.3 (7 Mar 2017)
+
+This is the third release candidate for zap's stable release. There are no
+breaking changes.
+
+Bugfixes:
+
+* [#339][]: Byte slices passed to `zap.Any` are now correctly treated as binary blobs
+  rather than `[]uint8`.
+
+Enhancements:
+
+* [#307][]: Users can opt into colored output for log levels.
+* [#353][]: In addition to hijacking the output of the standard library's
+  package-global logging functions, users can now construct a zap-backed
+  `log.Logger` instance.
+* [#311][]: Frames from common runtime functions and some of zap's internal
+  machinery are now omitted from stacktraces.
+
+Thanks to @ansel1 and @suyash for their contributions to this release.
+
+## v1.0.0-rc.2 (21 Feb 2017)
+
+This is the second release candidate for zap's stable release. It includes two
+breaking changes.
+
+Breaking changes:
+
+* [#316][]: Zap's global loggers are now fully concurrency-safe
+  (previously, users had to ensure that `ReplaceGlobals` was called before the
+  loggers were in use). However, they must now be accessed via the `L()` and
+  `S()` functions. Users can update their projects with
+
+  ```
+  gofmt -r "zap.L -> zap.L()" -w .
+  gofmt -r "zap.S -> zap.S()" -w .
+  ```
+* [#309][] and [#317][]: RC1 was mistakenly shipped with invalid
+  JSON and YAML struct tags on all config structs. This release fixes the tags
+  and adds static analysis to prevent similar bugs in the future.
+
+Bugfixes:
+
+* [#321][]: Redirecting the standard library's `log` output now
+  correctly reports the logger's caller.
+
+Enhancements:
+
+* [#325][] and [#333][]: Zap now transparently supports non-standard, rich
+  errors like those produced by `github.com/pkg/errors`.
+* [#326][]: Though `New(nil)` continues to return a no-op logger, `NewNop()` is
+  now preferred. Users can update their projects with `gofmt -r 'zap.New(nil) ->
+  zap.NewNop()' -w .`.
+* [#300][]: Incorrectly importing zap as `github.com/uber-go/zap` now returns a
+  more informative error.
+
+Thanks to @skipor and @chapsuk for their contributions to this release.
+
+## v1.0.0-rc.1 (14 Feb 2017)
+
+This is the first release candidate for zap's stable release. There are multiple
+breaking changes and improvements from the pre-release version. Most notably:
+
+* **Zap's import path is now "go.uber.org/zap"** — all users will
+  need to update their code.
+* User-facing types and functions remain in the `zap` package. Code relevant
+  largely to extension authors is now in the `zapcore` package.
+* The `zapcore.Core` type makes it easy for third-party packages to use zap's
+  internals but provide a different user-facing API.
+* `Logger` is now a concrete type instead of an interface.
+* A less verbose (though slower) logging API is included by default.
+* Package-global loggers `L` and `S` are included.
+* A human-friendly console encoder is included.
+* A declarative config struct allows common logger configurations to be managed
+  as configuration instead of code.
+* Sampling is more accurate, and doesn't depend on the standard library's shared
+  timer heap.
+
+## v0.1.0-beta.1 (6 Feb 2017)
+
+This is a minor version, tagged to allow users to pin to the pre-1.0 APIs and
+upgrade at their leisure. Since this is the first tagged release, there are no
+backward compatibility concerns and all functionality is new.
+
+Early zap adopters should pin to the 0.1.x minor version until they're ready to
+upgrade to the upcoming stable release.

+# Contributing
+
+We'd love your help making zap the very best structured logging library in Go!
+
+If you'd like to add new exported APIs, please [open an issue][open-issue]
+describing your proposal — discussing API changes ahead of time makes
+pull request review much smoother. In your issue, pull request, and any other
+communications, please remember to treat your fellow contributors with
+respect! We take our [code of conduct](CODE_OF_CONDUCT.md) seriously.
+
+Note that you'll need to sign [Uber's Contributor License Agreement][cla]
+before we can accept any of your contributions. If necessary, a bot will remind
+you to accept the CLA when you open your pull request.
+
+## Setup
+
+[Fork][fork], then clone the repository:
+
+```
+mkdir -p $GOPATH/src/go.uber.org
+cd $GOPATH/src/go.uber.org
+git clone git@github.com:your_github_username/zap.git
+cd zap
+git remote add upstream https://github.com/uber-go/zap.git
+git fetch upstream
+```
+
+Install zap's dependencies:
+
+```
+make dependencies
+```
+
+Make sure that the tests and the linters pass:
+
+```
+make test
+make lint
+```
+
+If you're not using the minor version of Go specified in the Makefile's
+`LINTABLE_MINOR_VERSIONS` variable, `make lint` doesn't do anything. This is
+fine, but it means that you'll only discover lint failures after you open your
+pull request.
+
+## Making Changes
+
+Start by creating a new branch for your changes:
+
+```
+cd $GOPATH/src/go.uber.org/zap
+git checkout master
+git fetch upstream
+git rebase upstream/master
+git checkout -b cool_new_feature
+```
+
+Make your changes, then ensure that `make lint` and `make test` still pass. If
+you're satisfied with your changes, push them to your fork.
+
+```
+git push origin cool_new_feature
+```
+
+Then use the GitHub UI to open a pull request.
+
+At this point, you're waiting on us to review your changes. We *try* to respond
+to issues and pull requests within a few business days, and we may suggest some
+improvements or alternatives. Once your changes are approved, one of the
+project maintainers will merge them.
+
+We're much more likely to approve your changes if you:
+
+* Add tests for new functionality.
+* Write a [good commit message][commit-message].
+* Maintain backward compatibility.

+# Frequently Asked Questions
+
+## Design
+
+### Why spend so much effort on logger performance?
+
+Of course, most applications won't notice the impact of a slow logger: they
+already take tens or hundreds of milliseconds for each operation, so an extra
+millisecond doesn't matter.
+
+On the other hand, why *not* make structured logging fast? The `SugaredLogger`
+isn't any harder to use than other logging packages, and the `Logger` makes
+structured logging possible in performance-sensitive contexts. Across a fleet
+of Go microservices, making each application even slightly more efficient adds
+up quickly.
+
+### Why aren't `Logger` and `SugaredLogger` interfaces?
+
+Unlike the familiar `io.Writer` and `http.Handler`, `Logger` and
+`SugaredLogger` interfaces would include *many* methods. As [Rob Pike points
+out][go-proverbs], "The bigger the interface, the weaker the abstraction."
+Interfaces are also rigid — *any* change requires releasing a new major
+version, since it breaks all third-party implementations.
+
+Making the `Logger` and `SugaredLogger` concrete types doesn't sacrifice much
+abstraction, and it lets us add methods without introducing breaking changes.
+Your applications should define and depend upon an interface that includes
+just the methods you use.
+
+### Why sample application logs?
+
+Applications often experience runs of errors, either because of a bug or
+because of a misbehaving user. Logging errors is usually a good idea, but it
+can easily make this bad situation worse: not only is your application coping
+with a flood of errors, it's also spending extra CPU cycles and I/O logging
+those errors. Since writes are typically serialized, logging limits throughput
+when you need it most.
+
+Sampling fixes this problem by dropping repetitive log entries. Under normal
+conditions, your application writes out every entry. When similar entries are
+logged hundreds or thousands of times each second, though, zap begins dropping
+duplicates to preserve throughput.
+
+### Why do the structured logging APIs take a message in addition to fields?
+
+Subjectively, we find it helpful to accompany structured context with a brief
+description. This isn't critical during development, but it makes debugging
+and operating unfamiliar systems much easier.
+
+More concretely, zap's sampling algorithm uses the message to identify
+duplicate entries. In our experience, this is a practical middle ground
+between random sampling (which often drops the exact entry that you need while
+debugging) and hashing the complete entry (which is prohibitively expensive).
+
+### Why include package-global loggers?
+
+Since so many other logging packages include a global logger, many
+applications aren't designed to accept loggers as explicit parameters.
+Changing function signatures is often a breaking change, so zap includes
+global loggers to simplify migration.
+
+Avoid them where possible.
+
+### Why include dedicated Panic and Fatal log levels?
+
+In general, application code should handle errors gracefully instead of using
+`panic` or `os.Exit`. However, every rule has exceptions, and it's common to
+crash when an error is truly unrecoverable. To avoid losing any information
+— especially the reason for the crash — the logger must flush any
+buffered entries before the process exits.
+
+Zap makes this easy by offering `Panic` and `Fatal` logging methods that
+automatically flush before exiting. Of course, this doesn't guarantee that
+logs will never be lost, but it eliminates a common error.
+
+See the discussion in uber-go/zap#207 for more details.
+
+### What's `DPanic`?
+
+`DPanic` stands for "panic in development." In development, it logs at
+`PanicLevel`; otherwise, it logs at `ErrorLevel`. `DPanic` makes it easier to
+catch errors that are theoretically possible, but shouldn't actually happen,
+*without* crashing in production.
+
+If you've ever written code like this, you need `DPanic`:
+
+```go
+if err != nil {
+  panic(fmt.Sprintf("shouldn't ever get here: %v", err))
+}
+```
+
+## Installation
+
+### What does the error `expects import "go.uber.org/zap"` mean?
+
+Either zap was installed incorrectly or you're referencing the wrong package
+name in your code.
+
+Zap's source code happens to be hosted on GitHub, but the [import
+path][import-path] is `go.uber.org/zap`. This gives us, the project
+maintainers, the freedom to move the source code if necessary. However, it
+means that you need to take a little care when installing and using the
+package.
+
+If you follow two simple rules, everything should work: install zap with `go
+get -u go.uber.org/zap`, and always import it in your code with `import
+"go.uber.org/zap"`. Your code shouldn't contain *any* references to
+`github.com/uber-go/zap`.
+
+## Usage
+
+### Does zap support log rotation?
+
+Zap doesn't natively support rotating log files, since we prefer to leave this
+to an external program like `logrotate`.
+
+However, it's easy to integrate a log rotation package like
+[`gopkg.in/natefinch/lumberjack.v2`][lumberjack] as a `zapcore.WriteSyncer`.
+
+```go
+// lumberjack.Logger is already safe for concurrent use, so we don't need to
+// lock it.
+w := zapcore.AddSync(&lumberjack.Logger{
+  Filename:   "/var/log/myapp/foo.log",
+  MaxSize:    500, // megabytes
+  MaxBackups: 3,
+  MaxAge:     28, // days
+})
+core := zapcore.NewCore(
+  zapcore.NewJSONEncoder(zap.NewProductionEncoderConfig()),
+  w,
+  zap.InfoLevel,
+)
+logger := zap.New(core)
+```
+
+## Extensions
+
+We'd love to support every logging need within zap itself, but we're only
+familiar with a handful of log ingestion systems, flag-parsing packages, and
+the like. Rather than merging code that we can't effectively debug and
+support, we'd rather grow an ecosystem of zap extensions.
+
+We're aware of the following extensions, but haven't used them ourselves:
+
+| Package | Integration |
+| --- | --- |
+| `github.com/tchap/zapext` | Sentry, syslog |
+| `github.com/fgrosse/zaptest` | Ginkgo |
+| `github.com/blendle/zapdriver` | Stackdriver |

+# :zap: zap [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov]
+
+Blazing fast, structured, leveled logging in Go.
+
+## Installation
+
+`go get -u go.uber.org/zap`
+
+Note that zap only supports the two most recent minor versions of Go.
+
+## Quick Start
+
+In contexts where performance is nice, but not critical, use the
+`SugaredLogger`. It's 4-10x faster than other structured logging
+packages and includes both structured and `printf`-style APIs.
+
+```go
+logger, _ := zap.NewProduction()
+defer logger.Sync() // flushes buffer, if any
+sugar := logger.Sugar()
+sugar.Infow("failed to fetch URL",
+  // Structured context as loosely typed key-value pairs.
+  "url", url,
+  "attempt", 3,
+  "backoff", time.Second,
+)
+sugar.Infof("Failed to fetch URL: %s", url)
+```
+
+When performance and type safety are critical, use the `Logger`. It's even
+faster than the `SugaredLogger` and allocates far less, but it only supports
+structured logging.
+
+```go
+logger, _ := zap.NewProduction()
+defer logger.Sync()
+logger.Info("failed to fetch URL",
+  // Structured context as strongly typed Field values.
+  zap.String("url", url),
+  zap.Int("attempt", 3),
+  zap.Duration("backoff", time.Second),
+)
+```
+
+See the [documentation][doc] and [FAQ](FAQ.md) for more details.
+
+## Performance
+
+For applications that log in the hot path, reflection-based serialization and
+string formatting are prohibitively expensive — they're CPU-intensive
+and make many small allocations. Put differently, using `encoding/json` and
+`fmt.Fprintf` to log tons of `interface{}`s makes your application slow.
+
+Zap takes a different approach. It includes a reflection-free, zero-allocation
+JSON encoder, and the base `Logger` strives to avoid serialization overhead
+and allocations wherever possible. By building the high-level `SugaredLogger`
+on that foundation, zap lets users *choose* when they need to count every
+allocation and when they'd prefer a more familiar, loosely typed API.
+
+As measured by its own [benchmarking suite][], not only is zap more performant
+than comparable structured logging packages — it's also faster than the
+standard library. Like all benchmarks, take these with a grain of salt.[1](#footnote-versions)
+
+Log a message and 10 fields:
+
+| Package | Time | Objects Allocated |

+| :zap: zap (sugared) | 4173 ns/op | 21 allocs/op |
+| zerolog | 16154 ns/op | 90 allocs/op |

+| :--- | :---: | :---: |
+| :zap: zap | 380 ns/op | 0 allocs/op |

+| log15 | 28788 ns/op | 79 allocs/op |
+| apex/log | 42063 ns/op | 115 allocs/op |
+
+Log a static string, without any context or `printf`-style templating:
+
+| Package | Time | Objects Allocated |
+| :--- | :---: | :---: |
+| :zap: zap | 361 ns/op | 0 allocs/op |
+| :zap: zap (sugared) | 534 ns/op | 2 allocs/op |
+| zerolog | 323 ns/op | 0 allocs/op |
+| standard library | 575 ns/op | 2 allocs/op |
+| go-kit | 922 ns/op | 13 allocs/op |
+| lion | 1413 ns/op | 10 allocs/op |
+| logrus | 2291 ns/op | 27 allocs/op |
+| apex/log | 3690 ns/op | 11 allocs/op |
+| log15 | 5954 ns/op | 26 allocs/op |
+
+## Development Status: Stable
+
+All APIs are finalized, and no breaking changes will be made in the 1.x series
+of releases. Users of semver-aware dependency management systems should pin
+zap to `^1`.
+
+## Contributing
+
+We encourage and support an active, healthy community of contributors —
+including you! Details are in the [contribution guide](CONTRIBUTING.md) and
+the [code of conduct](CODE_OF_CONDUCT.md). The zap maintainers keep an eye on
+issues and pull requests, but you can also report any negative conduct to
+oss-conduct@uber.com. That email list is a private, safe space; even the zap
+maintainers don't have access, so don't hesitate to hold us to a high
+standard.

+// Package zap provides fast, structured, leveled logging.
+//
+// For applications that log in the hot path, reflection-based serialization
+// and string formatting are prohibitively expensive - they're CPU-intensive
+// and make many small allocations. Put differently, using json.Marshal and
+// fmt.Fprintf to log tons of interface{} makes your application slow.
+//
+// Zap takes a different approach. It includes a reflection-free,
+// zero-allocation JSON encoder, and the base Logger strives to avoid
+// serialization overhead and allocations wherever possible. By building the
+// high-level SugaredLogger on that foundation, zap lets users choose when
+// they need to count every allocation and when they'd prefer a more familiar,
+// loosely typed API.
+//
+// Choosing a Logger
+//
+// In contexts where performance is nice, but not critical, use the
+// SugaredLogger. It's 4-10x faster than other structured logging packages and
+// supports both structured and printf-style logging. Like log15 and go-kit,
+// the SugaredLogger's structured logging APIs are loosely typed and accept a
+// variadic number of key-value pairs. (For more advanced use cases, they also
+// accept strongly typed fields - see the SugaredLogger.With documentation for
+// details.)
+//  sugar := zap.NewExample().Sugar()
+//  defer sugar.Sync()
+//  sugar.Infow("failed to fetch URL",
+//    "url", "http://example.com",
+//    "attempt", 3,
+//    "backoff", time.Second,
+//  )
+//  sugar.Infof("failed to fetch URL: %s", "http://example.com")
+//
+// By default, loggers are unbuffered. However, since zap's low-level APIs
+// allow buffering, calling Sync before letting your process exit is a good
+// habit.
+//
+// In the rare contexts where every microsecond and every allocation matter,
+// use the Logger. It's even faster than the SugaredLogger and allocates far
+// less, but it only supports strongly-typed, structured logging.
+//  logger := zap.NewExample()
+//  defer logger.Sync()
+//  logger.Info("failed to fetch URL",
+//    zap.String("url", "http://example.com"),
+//    zap.Int("attempt", 3),
+//    zap.Duration("backoff", time.Second),
+//  )
+//
+// Choosing between the Logger and SugaredLogger doesn't need to be an
+// application-wide decision: converting between the two is simple and
+// inexpensive.
+//   logger := zap.NewExample()
+//   defer logger.Sync()
+//   sugar := logger.Sugar()
+//   plain := sugar.Desugar()
+//
+// Configuring Zap
+//
+// The simplest way to build a Logger is to use zap's opinionated presets:
+// NewExample, NewProduction, and NewDevelopment. These presets build a logger
+// with a single function call:
+//  logger, err := zap.NewProduction()
+//  if err != nil {
+//    log.Fatalf("can't initialize zap logger: %v", err)
+//  }
+//  defer logger.Sync()
+//
+// Presets are fine for small projects, but larger projects and organizations
+// naturally require a bit more customization. For most users, zap's Config
+// struct strikes the right balance between flexibility and convenience. See
+// the package-level BasicConfiguration example for sample code.
+//
+// More unusual configurations (splitting output between files, sending logs
+// to a message queue, etc.) are possible, but require direct use of
+// go.uber.org/zap/zapcore. See the package-level AdvancedConfiguration
+// example for sample code.
+//
+// Extending Zap
+//
+// The zap package itself is a relatively thin wrapper around the interfaces
+// in go.uber.org/zap/zapcore. Extending zap to support a new encoding (e.g.,
+// BSON), a new log sink (e.g., Kafka), or something more exotic (perhaps an
+// exception aggregation service, like Sentry or Rollbar) typically requires
+// implementing the zapcore.Encoder, zapcore.WriteSyncer, or zapcore.Core
+// interfaces. See the zapcore documentation for details.
+//
+// Similarly, package authors can use the high-performance Encoder and Core
+// implementations in the zapcore package to build their own loggers.
+//
+// Frequently Asked Questions
+//
+// An FAQ covering everything from installation errors to design decisions is
+// available at https://github.com/uber-go/zap/blob/master/FAQ.md.

+
+### Lumberjack is a Go package for writing logs to rolling files.
+
+Package lumberjack provides a rolling logger.
+
+Note that this is v2.0 of lumberjack, and should be imported using gopkg.in
+thusly:
+
+    import "gopkg.in/natefinch/lumberjack.v2"
+
+The package name remains simply lumberjack, and the code resides at
+https://github.com/natefinch/lumberjack under the v2.0 branch.
+
+Lumberjack is intended to be one part of a logging infrastructure.
+It is not an all-in-one solution, but instead is a pluggable
+component at the bottom of the logging stack that simply controls the files
+to which logs are written.
+
+Lumberjack plays well with any logging package that can write to an
+io.Writer, including the standard library's log package.
+
+Lumberjack assumes that only one process is writing to the output files.
+Using the same lumberjack configuration from multiple processes on the same
+machine will result in improper behavior.
+
+
+**Example**
+
+To use lumberjack with the standard library's log package, just pass it into the SetOutput function when your application starts.
+
+Code:
+
+```go
+log.SetOutput(&lumberjack.Logger{
+    Filename:   "/var/log/myapp/foo.log",
+    MaxSize:    500, // megabytes
+    MaxBackups: 3,
+    MaxAge:     28, //days
+})
+```
+
+
+
+## type Logger
+``` go
+type Logger struct {
+    // Filename is the file to write logs to.  Backup log files will be retained
+    // in the same directory.  It uses -lumberjack.log in
+    // os.TempDir() if empty.
+    Filename string `json:"filename" yaml:"filename"`
+
+    // MaxSize is the maximum size in megabytes of the log file before it gets
+    // rotated. It defaults to 100 megabytes.
+    MaxSize int `json:"maxsize" yaml:"maxsize"`
+
+    // MaxAge is the maximum number of days to retain old log files based on the
+    // timestamp encoded in their filename.  Note that a day is defined as 24
+    // hours and may not exactly correspond to calendar days due to daylight
+    // savings, leap seconds, etc. The default is not to remove old log files
+    // based on age.
+    MaxAge int `json:"maxage" yaml:"maxage"`
+
+    // MaxBackups is the maximum number of old log files to retain.  The default
+    // is to retain all old log files (though MaxAge may still cause them to get
+    // deleted.)
+    MaxBackups int `json:"maxbackups" yaml:"maxbackups"`
+
+    // LocalTime determines if the time used for formatting the timestamps in
+    // backup files is the computer's local time.  The default is to use UTC
+    // time.
+    LocalTime bool `json:"localtime" yaml:"localtime"`
+    // contains filtered or unexported fields
+}
+```
+Logger is an io.WriteCloser that writes to the specified filename.
+
+Logger opens or creates the logfile on first Write.  If the file exists and
+is less than MaxSize megabytes, lumberjack will open and append to that file.
+If the file exists and its size is >= MaxSize megabytes, the file is renamed
+by putting the current time in a timestamp in the name immediately before the
+file's extension (or the end of the filename if there's no extension). A new
+log file is then created using original filename.
+
+Whenever a write would cause the current log file exceed MaxSize megabytes,
+the current file is closed, renamed, and a new log file created with the
+original name. Thus, the filename you give Logger is always the "current" log
+file.
+
+Backups use the log file name given to Logger, in the form `name-timestamp.ext`
+where name is the filename without the extension, timestamp is the time at which
+the log was rotated formatted with the time.Time format of
+`2006-01-02T15-04-05.000` and the extension is the original extension.  For
+example, if your Logger.Filename is `/var/log/foo/server.log`, a backup created
+at 6:30pm on Nov 11 2016 would use the filename
+`/var/log/foo/server-2016-11-04T18-30-00.000.log`
+
+### Cleaning Up Old Log Files
+Whenever a new logfile gets created, old log files may be deleted.  The most
+recent files according to the encoded timestamp will be retained, up to a
+number equal to MaxBackups (or all of them if MaxBackups is 0).  Any files
+with an encoded timestamp older than MaxAge days are deleted, regardless of
+MaxBackups.  Note that the time encoded in the timestamp is the rotation
+time, which may differ from the last time that file was written to.
+
+If MaxBackups and MaxAge are both 0, no old log files will be deleted.
+
+
+
+
+
+
+
+
+
+
+
+### func (\*Logger) Close
+``` go
+func (l *Logger) Close() error
+```
+Close implements io.Closer, and closes the current logfile.
+
+
+
+### func (\*Logger) Rotate
+``` go
+func (l *Logger) Rotate() error
+```
+Rotate causes Logger to close the existing log file and immediately create a
+new one.  This is a helper function for applications that want to initiate
+rotations outside of the normal rotation rules, such as in response to
+SIGHUP.  After rotating, this initiates a cleanup of old log files according
+to the normal rules.
+
+**Example**
+
+Example of how to rotate in response to SIGHUP.
+
+Code:
+
+```go
+l := &lumberjack.Logger{}
+log.SetOutput(l)
+c := make(chan os.Signal, 1)
+signal.Notify(c, syscall.SIGHUP)
+
+go func() {
+    for {
+        <-c
+        l.Rotate()
+    }
+}()
+```
+
+### func (\*Logger) Write
+``` go
+func (l *Logger) Write(p []byte) (n int, err error)
+```
+Write implements io.Writer.  If a write would cause the log file to be larger
+than MaxSize, the file is closed, renamed to include a timestamp of the
+current time, and a new log file is created using the original log file name.
+If the length of the write is greater than MaxSize, an error is returned.

+// Lumberjack is intended to be one part of a logging infrastructure.
+// It is not an all-in-one solution, but instead is a pluggable
+// component at the bottom of the logging stack that simply controls the files
+// to which logs are written.
+//
+// Lumberjack plays well with any logging package that can write to an
+// io.Writer, including the standard library's log package.
+//
+// Lumberjack assumes that only one process is writing to the output files.
+// Using the same lumberjack configuration from multiple processes on the same
+// machine will result in improper behavior.

+// Logger is an io.WriteCloser that writes to the specified filename.
+//
+// Logger opens or creates the logfile on first Write.  If the file exists and
+// is less than MaxSize megabytes, lumberjack will open and append to that file.
+// If the file exists and its size is >= MaxSize megabytes, the file is renamed
+// by putting the current time in a timestamp in the name immediately before the
+// file's extension (or the end of the filename if there's no extension). A new
+// log file is then created using original filename.
+//
+// Whenever a write would cause the current log file exceed MaxSize megabytes,
+// the current file is closed, renamed, and a new log file created with the
+// original name. Thus, the filename you give Logger is always the "current" log
+// file.
+//
+// Backups use the log file name given to Logger, in the form
+// `name-timestamp.ext` where name is the filename without the extension,
+// timestamp is the time at which the log was rotated formatted with the
+// time.Time format of `2006-01-02T15-04-05.000` and the extension is the
+// original extension.  For example, if your Logger.Filename is
+// `/var/log/foo/server.log`, a backup created at 6:30pm on Nov 11 2016 would
+// use the filename `/var/log/foo/server-2016-11-04T18-30-00.000.log`
+//
+// Cleaning Up Old Log Files
+//
+// Whenever a new logfile gets created, old log files may be deleted.  The most
+// recent files according to the encoded timestamp will be retained, up to a
+// number equal to MaxBackups (or all of them if MaxBackups is 0).  Any files
+// with an encoded timestamp older than MaxAge days are deleted, regardless of
+// MaxBackups.  Note that the time encoded in the timestamp is the rotation
+// time, which may differ from the last time that file was written to.

+
+   6. Trademarks. This License does not grant permission to use the trade

+# YAML support for the Go language
+
+Introduction
+------------
+
+The yaml package enables Go programs to comfortably encode and decode YAML
+values. It was developed within [Canonical](https://www.canonical.com) as
+part of the [juju](https://juju.ubuntu.com) project, and is based on a
+pure Go port of the well-known [libyaml](http://pyyaml.org/wiki/LibYAML)
+C library to parse and generate YAML data quickly and reliably.
+
+Compatibility
+-------------
+
+The yaml package supports most of YAML 1.1 and 1.2, including support for
+anchors, tags, map merging, etc. Multi-document unmarshalling is not yet
+implemented, and base-60 floats from YAML 1.1 are purposefully not
+supported since they're a poor design and are gone in YAML 1.2.
+
+Installation and usage
+----------------------
+
+The import path for the package is *gopkg.in/yaml.v2*.
+
+To install it, run:
+
+    go get gopkg.in/yaml.v2
+
+API documentation
+-----------------
+
+If opened in a browser, the import path itself leads to the API documentation:
+
+  * [https://gopkg.in/yaml.v2](https://gopkg.in/yaml.v2)
+
+API stability
+-------------
+
+The package API for yaml v2 will remain stable as described in [gopkg.in](https://gopkg.in).
+
+
+License
+-------
+
+The yaml package is licensed under the Apache License 2.0. Please see the LICENSE file for details.
+
+
+Example
+-------
+
+```Go
+package main
+
+import (
+        "fmt"
+        "log"
+
+        "gopkg.in/yaml.v2"
+)
+
+var data = `
+a: Easy!
+b:
+  c: 2
+  d: [3, 4]
+`
+
+// Note: struct fields must be public in order for unmarshal to
+// correctly populate the data.
+type T struct {
+        A string
+        B struct {
+                RenamedC int   `yaml:"c"`
+                D        []int `yaml:",flow"`
+        }
+}
+
+func main() {
+        t := T{}
+    
+        err := yaml.Unmarshal([]byte(data), &t)
+        if err != nil {
+                log.Fatalf("error: %v", err)
+        }
+        fmt.Printf("--- t:\n%v\n\n", t)
+    
+        d, err := yaml.Marshal(&t)
+        if err != nil {
+                log.Fatalf("error: %v", err)
+        }
+        fmt.Printf("--- t dump:\n%s\n\n", string(d))
+    
+        m := make(map[interface{}]interface{})
+    
+        err = yaml.Unmarshal([]byte(data), &m)
+        if err != nil {
+                log.Fatalf("error: %v", err)
+        }
+        fmt.Printf("--- m:\n%v\n\n", m)
+    
+        d, err = yaml.Marshal(&m)
+        if err != nil {
+                log.Fatalf("error: %v", err)
+        }
+        fmt.Printf("--- m dump:\n%s\n\n", string(d))
+}
+```
+
+This example will generate the following output:
+
+```
+--- t:
+{Easy! {2 [3 4]}}
+
+--- t dump:
+a: Easy!
+b:
+  c: 2
+  d: [3, 4]
+
+
+--- m:
+map[a:Easy! b:map[c:2 d:[3 4]]]
+
+--- m dump:
+a: Easy!
+b:
+  c: 2
+  d:
+  - 3
+  - 4
+```

+// Introduction
+// ************
+//
+// The following notes assume that you are familiar with the YAML specification
+// (http://yaml.org/spec/1.2/spec.html).  We mostly follow it, although in
+// some cases we are less restrictive that it requires.
+//
+// The process of transforming a YAML stream into a sequence of events is
+// divided on two steps: Scanning and Parsing.
+//
+// The Scanner transforms the input stream into a sequence of tokens, while the
+// parser transform the sequence of tokens produced by the Scanner into a
+// sequence of parsing events.
+//
+// The Scanner is rather clever and complicated. The Parser, on the contrary,
+// is a straightforward implementation of a recursive-descendant parser (or,
+// LL(1) parser, as it is usually called).
+//
+// Actually there are two issues of Scanning that might be called "clever", the
+// rest is quite straightforward.  The issues are "block collection start" and
+// "simple keys".  Both issues are explained below in details.
+//
+// Here the Scanning step is explained and implemented.  We start with the list
+// of all the tokens produced by the Scanner together with short descriptions.
+//
+// Now, tokens:
+//
+//      STREAM-START(encoding)          # The stream start.
+//      STREAM-END                      # The stream end.
+//      VERSION-DIRECTIVE(major,minor)  # The '%YAML' directive.
+//      TAG-DIRECTIVE(handle,prefix)    # The '%TAG' directive.
+//      DOCUMENT-START                  # '---'
+//      DOCUMENT-END                    # '...'
+//      BLOCK-SEQUENCE-START            # Indentation increase denoting a block
+//      BLOCK-MAPPING-START             # sequence or a block mapping.
+//      BLOCK-END                       # Indentation decrease.
+//      FLOW-SEQUENCE-START             # '['
+//      FLOW-SEQUENCE-END               # ']'
+//      BLOCK-SEQUENCE-START            # '{'
+//      BLOCK-SEQUENCE-END              # '}'
+//      BLOCK-ENTRY                     # '-'
+//      FLOW-ENTRY                      # ','
+//      KEY                             # '?' or nothing (simple keys).
+//      VALUE                           # ':'
+//      ALIAS(anchor)                   # '*anchor'
+//      ANCHOR(anchor)                  # '&anchor'
+//      TAG(handle,suffix)              # '!handle!suffix'
+//      SCALAR(value,style)             # A scalar.
+//
+// The following two tokens are "virtual" tokens denoting the beginning and the
+// end of the stream:
+//
+//      STREAM-START(encoding)
+//      STREAM-END
+//
+// We pass the information about the input stream encoding with the
+// STREAM-START token.
+//
+// The next two tokens are responsible for tags:
+//
+//      VERSION-DIRECTIVE(major,minor)
+//      TAG-DIRECTIVE(handle,prefix)
+//
+// Example:
+//
+//      %YAML   1.1
+//      %TAG    !   !foo
+//      %TAG    !yaml!  tag:yaml.org,2002:
+//      ---
+//
+// The correspoding sequence of tokens:
+//
+//      STREAM-START(utf-8)
+//      VERSION-DIRECTIVE(1,1)
+//      TAG-DIRECTIVE("!","!foo")
+//      TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:")
+//      DOCUMENT-START
+//      STREAM-END
+//
+// Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole
+// line.
+//
+// The document start and end indicators are represented by:
+//
+//      DOCUMENT-START
+//      DOCUMENT-END
+//
+// Note that if a YAML stream contains an implicit document (without '---'
+// and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be
+// produced.
+//
+// In the following examples, we present whole documents together with the
+// produced tokens.
+//
+//      1. An implicit document:
+//
+//          'a scalar'
+//
+//      Tokens:
+//
+//          STREAM-START(utf-8)
+//          SCALAR("a scalar",single-quoted)
+//          STREAM-END
+//
+//      2. An explicit document:
+//
+//          ---
+//          'a scalar'
+//          ...
+//
+//      Tokens:
+//
+//          STREAM-START(utf-8)
+//          DOCUMENT-START
+//          SCALAR("a scalar",single-quoted)
+//          DOCUMENT-END
+//          STREAM-END
+//
+//      3. Several documents in a stream:
+//
+//          'a scalar'
+//          ---
+//          'another scalar'
+//          ---
+//          'yet another scalar'
+//
+//      Tokens:
+//
+//          STREAM-START(utf-8)
+//          SCALAR("a scalar",single-quoted)
+//          DOCUMENT-START
+//          SCALAR("another scalar",single-quoted)
+//          DOCUMENT-START
+//          SCALAR("yet another scalar",single-quoted)
+//          STREAM-END
+//
+// We have already introduced the SCALAR token above.  The following tokens are
+// used to describe aliases, anchors, tag, and scalars:
+//
+//      ALIAS(anchor)
+//      ANCHOR(anchor)
+//      TAG(handle,suffix)
+//      SCALAR(value,style)
+//
+// The following series of examples illustrate the usage of these tokens:
+//
+//      1. A recursive sequence:
+//
+//          &A [ *A ]
+//
+//      Tokens:
+//
+//          STREAM-START(utf-8)
+//          ANCHOR("A")
+//          FLOW-SEQUENCE-START
+//          ALIAS("A")
+//          FLOW-SEQUENCE-END
+//          STREAM-END
+//
+//      2. A tagged scalar:
+//
+//          !!float "3.14"  # A good approximation.
+//
+//      Tokens:
+//
+//          STREAM-START(utf-8)
+//          TAG("!!","float")
+//          SCALAR("3.14",double-quoted)
+//          STREAM-END
+//
+//      3. Various scalar styles:
+//
+//          --- # Implicit empty plain scalars do not produce tokens.
+//          --- a plain scalar
+//          --- 'a single-quoted scalar'
+//          --- "a double-quoted scalar"
+//          --- |-
+//            a literal scalar
+//          --- >-
+//            a folded
+//            scalar
+//
+//      Tokens:
+//
+//          STREAM-START(utf-8)
+//          DOCUMENT-START
+//          DOCUMENT-START
+//          SCALAR("a plain scalar",plain)
+//          DOCUMENT-START
+//          SCALAR("a single-quoted scalar",single-quoted)
+//          DOCUMENT-START
+//          SCALAR("a double-quoted scalar",double-quoted)
+//          DOCUMENT-START
+//          SCALAR("a literal scalar",literal)
+//          DOCUMENT-START
+//          SCALAR("a folded scalar",folded)
+//          STREAM-END
+//
+// Now it's time to review collection-related tokens. We will start with
+// flow collections:
+//
+//      FLOW-SEQUENCE-START
+//      FLOW-SEQUENCE-END
+//      FLOW-MAPPING-START
+//      FLOW-MAPPING-END
+//      FLOW-ENTRY
+//      KEY
+//      VALUE
+//
+// The tokens FLOW-SEQUENCE-START, FLOW-SEQUENCE-END, FLOW-MAPPING-START, and
+// FLOW-MAPPING-END represent the indicators '[', ']', '{', and '}'
+// correspondingly.  FLOW-ENTRY represent the ',' indicator.  Finally the
+// indicators '?' and ':', which are used for denoting mapping keys and values,
+// are represented by the KEY and VALUE tokens.
+//
+// The following examples show flow collections:
+//
+//      1. A flow sequence:
+//
+//          [item 1, item 2, item 3]
+//
+//      Tokens:
+//
+//          STREAM-START(utf-8)
+//          FLOW-SEQUENCE-START
+//          SCALAR("item 1",plain)
+//          FLOW-ENTRY
+//          SCALAR("item 2",plain)
+//          FLOW-ENTRY
+//          SCALAR("item 3",plain)
+//          FLOW-SEQUENCE-END
+//          STREAM-END
+//
+//      2. A flow mapping:
+//
+//          {
+//              a simple key: a value,  # Note that the KEY token is produced.
+//              ? a complex key: another value,
+//          }
+//
+//      Tokens:
+//
+//          STREAM-START(utf-8)
+//          FLOW-MAPPING-START
+//          KEY
+//          SCALAR("a simple key",plain)
+//          VALUE
+//          SCALAR("a value",plain)
+//          FLOW-ENTRY
+//          KEY
+//          SCALAR("a complex key",plain)
+//          VALUE
+//          SCALAR("another value",plain)
+//          FLOW-ENTRY
+//          FLOW-MAPPING-END
+//          STREAM-END
+//
+// A simple key is a key which is not denoted by the '?' indicator.  Note that
+// the Scanner still produce the KEY token whenever it encounters a simple key.
+//
+// For scanning block collections, the following tokens are used (note that we
+// repeat KEY and VALUE here):
+//
+//      BLOCK-SEQUENCE-START
+//      BLOCK-MAPPING-START
+//      BLOCK-END
+//      BLOCK-ENTRY
+//      KEY
+//      VALUE
+//
+// The tokens BLOCK-SEQUENCE-START and BLOCK-MAPPING-START denote indentation
+// increase that precedes a block collection (cf. the INDENT token in Python).
+// The token BLOCK-END denote indentation decrease that ends a block collection
+// (cf. the DEDENT token in Python).  However YAML has some syntax pecularities
+// that makes detections of these tokens more complex.
+//
+// The tokens BLOCK-ENTRY, KEY, and VALUE are used to represent the indicators
+// '-', '?', and ':' correspondingly.
+//
+// The following examples show how the tokens BLOCK-SEQUENCE-START,
+// BLOCK-MAPPING-START, and BLOCK-END are emitted by the Scanner:
+//
+//      1. Block sequences:
+//
+//          - item 1
+//          - item 2
+//          -
+//            - item 3.1
+//            - item 3.2
+//          -
+//            key 1: value 1
+//            key 2: value 2
+//
+//      Tokens:
+//
+//          STREAM-START(utf-8)
+//          BLOCK-SEQUENCE-START
+//          BLOCK-ENTRY
+//          SCALAR("item 1",plain)
+//          BLOCK-ENTRY
+//          SCALAR("item 2",plain)
+//          BLOCK-ENTRY
+//          BLOCK-SEQUENCE-START
+//          BLOCK-ENTRY
+//          SCALAR("item 3.1",plain)
+//          BLOCK-ENTRY
+//          SCALAR("item 3.2",plain)
+//          BLOCK-END
+//          BLOCK-ENTRY
+//          BLOCK-MAPPING-START
+//          KEY
+//          SCALAR("key 1",plain)
+//          VALUE

+//          BLOCK-END
+//          STREAM-END
+//
+//      2. Block mappings:
+//
+//          a simple key: a value   # The KEY token is produced here.
+//          ? a complex key
+//          : another value
+//          a mapping:
+//            key 1: value 1
+//            key 2: value 2
+//          a sequence:

+//          KEY
+//          SCALAR("a simple key",plain)

+### Please review our Code of Conduct 
+
+Thank you for visiting the virtual office of the Mattermost core team, and for your interest in the [Mattermost open source project](http://www.mattermost.org/vision/#mattermost-teams-v1). 
+
+This is the virtual office of for the Mattermost core team, project contributors, testers and invited guests. Please behave here as you would as a guest in an office space where people are working. 
+
+Important notes:
+
+##### 1) This is a virtual office, not a demo server
+
+You can use [Mattermost install guides](http://www.mattermost.org/installation/) to install your own version of Matterrmost if you want to experiment with features. 
+
+##### 2) This is a virtual office, not the Mattermost public forum (the [forum](https://forum.mattermost.org/) is here)
+
+Please do not create public channels or private groups. If you want to discuss something that’s not a topic started by the core team, please start a topic on the [public forum](https://forum.mattermost.org/), or discuss in the [IRC Public Discussion channel](https://pre-release.mattermost.com/core/channels/irc#). 
+
+If people are responding to your @ mentions, it’s fine to continue a conversation. If your mentions have been repeatedly been ignored, please stop. 
+
+Please move conversations to the appropriate channel by topic and do not post long threads in the Reception area. Moderators delete or move your messages if the topic isn't relevant to 300+ members viewing the Reception area. 
+
+##### 3) This is a virtual office, not a substitute for community systems
+
+There are standard community systems for [bugs, feature ideas, and troubleshooting help](http://docs.mattermost.com/process/community-systems.html). 
+
+If you receive a request from the core team, or matterbot, to change your behavior in the office, please follow the request or leave the office. 
+
+In addition to the basics discussed above the [Contributor Code of Conduct](http://contributor-covenant.org/version/1/3/0/code_of_conduct.txt) also applies.
