It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +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 this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. 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 not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +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 +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the 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 +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "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 +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY 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 +LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey 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 library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library 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.

Adapted Material means material subject to Copyright and Similar + Rights that is derived from or based upon the Licensed Material + and in which the Licensed Material is translated, altered, + arranged, transformed, or otherwise modified in a manner requiring + permission under the Copyright and Similar Rights held by the + Licensor.

Adapter's License means the license You apply to Your Copyright + and Similar Rights in Your contributions to Adapted Material in + accordance with the terms and conditions of this Public License. + + c.

Copyright and Similar Rights means copyright and/or similar rights + closely related to copyright including, without limitation, + performance, broadcast, sound recording, and Sui Generis Database + Rights, without regard to how the rights are labeled or + categorized. For purposes of this Public License, the rights + specified in Section 2(b)(1)-(2) are not Copyright and Similar + Rights. + + e. Effective Technological Measures means those measures that, in the + absence of proper authority, may not be circumvented under laws + fulfilling obligations under Article 11 of the WIPO Copyright + Treaty adopted on December 20, 1996, and/or similar international + agreements. + + f. Exceptions and Limitations means fair use, fair dealing, and/or + any other exception or limitation to Copyright and Similar Rights + that applies to Your use of the Licensed Material. + + g.

Licensed Material means the artistic or literary work, database, + or other material to which the Licensor applied this Public + License. + + i.

Sui Generis Database Rights means rights other than copyright + resulting from Directive 96/9/EC of the European Parliament and of + the Council of 11 March 1996 on the legal protection of databases, + as amended and/or succeeded, as well as other essentially + equivalent rights anywhere in the world. + + m.

Exceptions and Limitations. For the avoidance of doubt, where + Exceptions and Limitations apply to Your use, this Public + License does not apply, and You do not need to comply with + its terms and conditions. + + 3. Term.

The + Licensor authorizes You to exercise the Licensed Rights in + all media and formats whether now known or hereafter created, + and to make technical modifications necessary to do so. The + Licensor waives and/or agrees not to assert any right or + authority to forbid You from making technical modifications + necessary to exercise the Licensed Rights, including + technical modifications necessary to circumvent Effective + Technological Measures. For purposes of this Public License, + simply making modifications authorized by this Section 2(a) + (4) never produces Adapted Material. + + 5. Downstream recipients. + + a. Offer from the Licensor -- Licensed Material. Every + recipient of the Licensed Material automatically + receives an offer from the Licensor to exercise the + Licensed Rights under the terms and conditions of this + Public License. + + b.

No downstream restrictions. You may not offer or impose + any additional or different terms or conditions on, or + apply any Effective Technological Measures to, the + Licensed Material if doing so restricts exercise of the + Licensed Rights by any recipient of the Licensed + Material. + + 6.

Nothing in this Public License constitutes or + may be construed as permission to assert or imply that You + are, or that Your use of the Licensed Material is, connected + with, or sponsored, endorsed, or granted official status by, + the Licensor or others designated to receive attribution as + provided in Section 3(a)(1)(A)(i). + + b. Other rights. + + 1. Moral rights, such as the right of integrity, are not + licensed under this Public License, nor are publicity, + privacy, and/or other similar personality rights; however, to + the extent possible, the Licensor waives and/or agrees not to + assert any such rights held by the Licensor to the limited + extent necessary to allow You to exercise the Licensed + Rights, but not otherwise. + + 2. Patent and trademark rights are not licensed under this + Public License. + + 3. To the extent possible, the Licensor waives any right to + collect royalties from You for the exercise of the Licensed + Rights, whether directly or through a collecting society + under any voluntary or waivable statutory or compulsory + licensing scheme. In all other cases the Licensor expressly + reserves any right to collect such royalties. + + +Section 3 -- License Conditions. + +Your exercise of the Licensed Rights is expressly made subject to the +following conditions. + + a. Attribution. + + 1. If You Share the Licensed Material (including in modified + form), You must: + + a. retain the following if it is supplied by the Licensor + with the Licensed Material: + + i. identification of the creator(s) of the Licensed + Material and any others designated to receive + attribution, in any reasonable manner requested by + the Licensor (including by pseudonym if + designated); + + ii. a copyright notice; + + iii. a notice that refers to this Public License; + + iv. a notice that refers to the disclaimer of + warranties; + + v. a URI or hyperlink to the Licensed Material to the + extent reasonably practicable; + + b. indicate if You modified the Licensed Material and + retain an indication of any previous modifications; and + + c. indicate the Licensed Material is licensed under this + Public License, and include the text of, or the URI or + hyperlink to, this Public License. + + 2. You may satisfy the conditions in Section 3(a)(1) in any + reasonable manner based on the medium, means, and context in + which You Share the Licensed Material. For example, it may be + reasonable to satisfy the conditions by providing a URI or + hyperlink to a resource that includes the required + information. + + 3. If requested by the Licensor, You must remove any of the + information required by Section 3(a)(1)(A) to the extent + reasonably practicable. + + b. ShareAlike. + + In addition to the conditions in Section 3(a), if You Share + Adapted Material You produce, the following conditions also apply. + + 1. The Adapter's License You apply must be a Creative Commons + license with the same License Elements, this version or + later, or a BY-SA Compatible License. + + 2. You must include the text of, or the URI or hyperlink to, the + Adapter's License You apply. You may satisfy this condition + in any reasonable manner based on the medium, means, and + context in which You Share Adapted Material. + + 3. You may not offer or impose any additional or different terms + or conditions on, or apply any Effective Technological + Measures to, Adapted Material that restrict exercise of the + rights granted under the Adapter's License You apply. + + +Section 4 -- Sui Generis Database Rights. + +Where the Licensed Rights include Sui Generis Database Rights that +apply to Your use of the Licensed Material: + + a. for the avoidance of doubt, Section 2(a)(1) grants You the right + to extract, reuse, reproduce, and Share all or a substantial + portion of the contents of the database; + + b. if You include all or a substantial portion of the database + contents in a database in which You have Sui Generis Database + Rights, then the database in which You have Sui Generis Database + Rights (but not its individual contents) is Adapted Material, + + including for purposes of Section 3(b); and + c. You must comply with the conditions in Section 3(a) if You Share + all or a substantial portion of the contents of the database. + +For the avoidance of doubt, this Section 4 supplements and does not +replace Your obligations under this Public License where the Licensed +Rights include other Copyright and Similar Rights. + + +Section 5 -- Disclaimer of Warranties and Limitation of Liability. + + a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE + EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS + AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF + ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, + IMPLIED, STATUTORY, OR OTHER.

WHERE DISCLAIMERS OF WARRANTIES ARE NOT + ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU. + + b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE + TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, + NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, + INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, + COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR + USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN + ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR + DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR + IN PART, THIS LIMITATION MAY NOT APPLY TO YOU. + + c. The disclaimer of warranties and limitation of liability provided + above shall be interpreted in a manner that, to the extent + possible, most closely approximates an absolute disclaimer and + waiver of all liability. + + +Section 6 -- Term and Termination. + + a. This Public License applies for the term of the Copyright and + Similar Rights licensed here. However, if You fail to comply with + this Public License, then Your rights under this Public License + terminate automatically. + + b. Where Your right to use the Licensed Material has terminated under + Section 6(a), it reinstates: + + 1. automatically as of the date the violation is cured, provided + it is cured within 30 days of Your discovery of the + violation; or + + 2. upon express reinstatement by the Licensor. + + For the avoidance of doubt, this Section 6(b) does not affect any + right the Licensor may have to seek remedies for Your violations + of this Public License. + + c. For the avoidance of doubt, the Licensor may also offer the + Licensed Material under separate terms or conditions or stop + distributing the Licensed Material at any time; however, doing so + will not terminate this Public License. + + d. Sections 1, 5, 6, 7, and 8 survive termination of this Public + License. + + +Section 7 -- Other Terms and Conditions. + + a. The Licensor shall not be bound by any additional or different + terms or conditions communicated by You unless expressly agreed. + + b. Any arrangements, understandings, or agreements regarding the + Licensed Material not stated herein are separate from and + independent of the terms and conditions of this Public License. + + +Section 8 -- Interpretation. + + a. For the avoidance of doubt, this Public License does not, and + shall not be interpreted to, reduce, limit, restrict, or impose + conditions on any use of the Licensed Material that could lawfully + be made without permission under this Public License. + + b. To the extent possible, if any provision of this Public License is + deemed unenforceable, it shall be automatically reformed to the + minimum extent necessary to make it enforceable. If the provision + cannot be reformed, it shall be severed from this Public License + without affecting the enforceability of the remaining terms and + conditions. + + c. No term or condition of this Public License will be waived and no + failure to comply consented to unless expressly agreed to by the + Licensor. + + d. Nothing in this Public License constitutes or may be interpreted + as a limitation upon, or waiver of, any privileges and immunities + that apply to the Licensor or You, including from the legal + processes of any jurisdiction or authority. + + +======================================================================= + +Creative Commons is not a party to its public licenses. +Notwithstanding, Creative Commons may elect to apply one of its public +licenses to material it publishes and in those instances will be +considered the "Licensor."

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.

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.

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.

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.

However, there might be a way to implement -that feature *on top of* libcontainer. - -### Discuss your design on the mailing list - -We recommend discussing your plans [on the mailing -list](https://groups.google.com/forum/?fromgroups#!forum/libcontainer) -before starting to code - especially for more ambitious contributions. -This gives other contributors a chance to point you in the right -direction, give feedback on your design, and maybe point out if someone -else is working on the same thing. - -### Create issues... - -Any significant improvement should be documented as [a GitHub -issue](https://github.com/docker/libcontainer/issues) before anybody -starts working on it. - -### ...but check for existing issues first! - -Please take a moment to check that an issue doesn't already exist -documenting your bug report or improvement proposal. If it does, it -never hurts to add a quick "+1" or "I have this problem too". This will -help prioritize the most common problems and requests. - -### Conventions - -Fork the repo and make changes on your fork in a feature branch: - -- If it's a bugfix branch, name it XXX-something where XXX is the number of the - issue -- If it's a feature branch, create an enhancement issue to announce your - intentions, and name it XXX-something where XXX is the number of the issue. - -Submit unit tests for your changes. Go has a great test framework built in; use -it! Take a look at existing tests for inspiration. Run the full test suite on -your branch before submitting a pull request. - -Update the documentation when creating or modifying features. Test -your documentation changes for clarity, concision, and correctness, as -well as a clean documentation build. See ``docs/README.md`` for more -information on building the docs and how docs get released. - -Write clean code. Universally formatted code promotes ease of writing, reading, -and maintenance. Always run `gofmt -s -w file.go` on each changed file before -committing your changes. Most editors have plugins that do this automatically. - -Pull requests descriptions should be as clear as possible and include a -reference to all the issues that they address. - -Pull requests must not contain commits from other users or branches. - -Commit messages must start with a capitalized and short summary (max. 50 -chars) written in the imperative, followed by an optional, more detailed -explanatory text which is separated from the summary by an empty line. - -Code review comments may be added to your pull request. Discuss, then make the -suggested modifications and push additional commits to your feature branch. Be -sure to post a comment after pushing. The new commits will show up in the pull -request automatically, but the reviewers will not be notified unless you -comment. - -Before the pull request is merged, make sure that you squash your commits into -logical units of work using `git rebase -i` and `git push -f`. After every -commit the test suite should be passing. Include documentation changes in the -same commit so that a revert would remove all traces of the feature or fix. - -Commits that fix or close an issue should include a reference like `Closes #XXX` -or `Fixes #XXX`, which will automatically close the issue when merged. - -### Testing - -Make sure you include suitable tests, preferably unit tests, in your pull request -and that all the tests pass. - -*Instructions for running tests to be added.* - -### Merge approval - -libcontainer maintainers use LGTM (looks good to me) in comments on the code review -to indicate acceptance. - -A change requires LGTMs from at lease two maintainers. One of those must come from -a maintainer of the component affected. For example, if a change affects `netlink/` -and `security`, it needs at least one LGTM from a maintainer of each. Maintainers -only need one LGTM as presumably they LGTM their own change. - -For more details see [MAINTAINERS.md](MAINTAINERS.md) - -### Sign your work - -The sign-off is a simple line at the end of the explanation for the -patch, which certifies that you wrote it or otherwise have the right to -pass it on as an open-source patch. The rules are pretty simple: if you -can certify the below (from -[developercertificate.org](http://developercertificate.org/)): - -``` -Developer Certificate of Origin -Version 1.1 - -Copyright (C) 2004, 2006 The Linux Foundation and its contributors. -660 York Street, Suite 102, -San Francisco, CA 94110 USA - -Everyone is permitted to copy and distribute verbatim copies of this -license document, but changing it is not allowed. - - -Developer's Certificate of Origin 1.1 - -By making a contribution to this project, I certify that: - -(a) The contribution was created in whole or in part by me and I - have the right to submit it under the open source license - indicated in the file; or - -(b) The contribution is based upon previous work that, to the best - of my knowledge, is covered under an appropriate open source - license and I have the right under that license to submit that - work with modifications, whether created in whole or in part - by me, under the same open source license (unless I am - permitted to submit under a different license), as indicated - in the file; or - -(c) The contribution was provided directly to me by some other - person who certified (a), (b) or (c) and I have not modified - it. - -(d) I understand and agree that this project and the contribution - are public and that a record of the contribution (including all - personal information I submit with it, including my sign-off) is - maintained indefinitely and may be redistributed consistent with - this project or the open source license(s) involved. -``` - -then you just add a line to every git commit message: - - Docker-DCO-1.1-Signed-off-by: Joe Smith (github: github_handle) - -using your real name (sorry, no pseudonyms or anonymous contributions.) - -One way to automate this, is customise your get ``commit.template`` by adding -a ``prepare-commit-msg`` hook to your libcontainer checkout: - -``` -curl -o .git/hooks/prepare-commit-msg https://raw.githubusercontent.com/docker/docker/master/contrib/prepare-commit-msg.hook && chmod +x .git/hooks/prepare-commit-msg -``` - -* Note: the above script expects to find your GitHub user name in ``git config --get github.user`` - -#### Small patch exception - -There are several exceptions to the signing requirement.

This includes IRC, GitHub requests and the mailing - list. -* 4) Make sure their component respects the philosophy, design and - roadmap of the project. - -## How are decisions made? - -Short answer: with pull requests to the libcontainer repository. - -libcontainer is an open-source project with an open design philosophy. This -means that the repository is the source of truth for EVERY aspect of the -project, including its philosophy, design, roadmap and APIs. *If it's -part of the project, it's in the repo. It's in the repo, it's part of -the project.* - -As a result, all decisions can be expressed as changes to the -repository. An implementation change is a change to the source code. An -API change is a change to the API specification. A philosophy change is -a change to the philosophy manifesto. And so on. - -All decisions affecting libcontainer, big and small, follow the same 3 steps: - -* Step 1: Open a pull request. Anyone can do this. - -* Step 2: Discuss the pull request. Anyone can do this. - -* Step 3: Accept (`LGTM`) or refuse a pull request. The relevant maintainers do -this (see below "Who decides what?") - - -## Who decides what? - -All decisions are pull requests, and the relevant maintainers make -decisions by accepting or refusing the pull request. Review and acceptance -by anyone is denoted by adding a comment in the pull request: `LGTM`. -However, only currently listed `MAINTAINERS` are counted towards the required -two LGTMs. - -libcontainer follows the timeless, highly efficient and totally unfair system -known as [Benevolent dictator for life](http://en.wikipedia.org/wiki/Benevolent_Dictator_for_Life), with Michael Crosby in the role of BDFL. -This means that all decisions are made by default by Michael. Since making -every decision himself would be highly un-scalable, in practice decisions -are spread across multiple maintainers. - -The relevant maintainers for a pull request can be worked out in two steps: - -* Step 1: Determine the subdirectories affected by the pull request. This - might be `netlink/` and `security/`, or any other part of the repo. - -* Step 2: Find the `MAINTAINERS` file which affects this directory. If the - directory itself does not have a `MAINTAINERS` file, work your way up - the repo hierarchy until you find one. - -### I'm a maintainer, and I'm going on holiday - -Please let your co-maintainers and other contributors know by raising a pull -request that comments out your `MAINTAINERS` file entry using a `#`. - -### I'm a maintainer, should I make pull requests too? - -Yes. Nobody should ever push to master directly.

You can customize it all you -want: - -```go -package main - -import ( - "os" - log "github.com/Sirupsen/logrus" - "github.com/Sirupsen/logrus/hooks/airbrake" -) - -func init() { - // Log as JSON instead of the default ASCII formatter. - log.SetFormatter(&log.JSONFormatter{}) - - // Use the Airbrake hook to report errors that have Error severity or above to - // an exception tracker. You can create custom hooks, see the Hooks section. - log.AddHook(airbrake.NewHook("https://example.com", "xyz", "development")) - - // Output to stderr instead of stdout, could also be a file. - log.SetOutput(os.Stderr) - - // Only log the warning severity or above. - log.SetLevel(log.WarnLevel) -} - -func main() { - log.WithFields(log.Fields{ - "animal": "walrus", - "size": 10, - }).Info("A group of walrus emerges from the ocean") - - log.WithFields(log.Fields{ - "omg": true, - "number": 122, - }).Warn("The group's number increased tremendously!") - - log.WithFields(log.Fields{ - "omg": true, - "number": 100, - }).Fatal("The ice breaks!") - - // A common pattern is to re-use fields between logging statements by re-using - // the logrus.Entry returned from WithFields() - contextLogger := log.WithFields(log.Fields{ - "common": "this is a common field", - "other": "I also should be logged always", - }) - - contextLogger.Info("I'll be logged with common and other field") - contextLogger.Info("Me too") -} -``` - -For more advanced usage such as logging to multiple locations from the same -application, you can also create an instance of the `logrus` Logger: - -```go -package main - -import ( - "github.com/Sirupsen/logrus" -) - -// Create a new instance of the logger. You can have any number of instances. -var log = logrus.New() - -func main() { - // The API for setting attributes is a little different than the package level - // exported logger. See Godoc. - log.Out = os.Stderr - - log.WithFields(logrus.Fields{ - "animal": "walrus", - "size": 10, - }).Info("A group of walrus emerges from the ocean") -} -``` - -#### Fields - -Logrus encourages careful, structured logging though logging fields instead of -long, unparseable error messages. For example, instead of: `log.Fatalf("Failed -to send event %s to topic %s with key %d")`, you should log the much more -discoverable: - -```go -log.WithFields(log.Fields{ - "event": event, - "topic": topic, - "key": key, -}).Fatal("Failed to send event") -``` - -We've found this API forces you to think about logging in a way that produces -much more useful logging messages. We've been in countless situations where just -a single added field to a log statement that was already there would've saved us -hours. The `WithFields` call is optional. - -In general, with Logrus using any of the `printf`-family functions should be -seen as a hint you should add a field, however, you can still use the -`printf`-family functions with Logrus. - -#### Hooks - -You can add hooks for logging levels. For example to send errors to an exception -tracking service on `Error`, `Fatal` and `Panic`, info to StatsD or log to -multiple places simultaneously, e.g. syslog. - -Logrus comes with [built-in hooks](hooks/). Add those, or your custom hook, in -`init`: - -```go -import ( - log "github.com/Sirupsen/logrus" - "github.com/Sirupsen/logrus/hooks/airbrake" - "github.com/Sirupsen/logrus/hooks/syslog" - "log/syslog" -) - -func init() { - log.AddHook(airbrake.NewHook("https://example.com", "xyz", "development")) - - hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "") - if err != nil { - log.Error("Unable to connect to local syslog daemon") - } else { - log.AddHook(hook) - } -} -``` - - -| Hook | Description | -| ----- | ----------- | -| [Airbrake](https://github.com/Sirupsen/logrus/blob/master/hooks/airbrake/airbrake.go) | Send errors to an exception tracking service compatible with the Airbrake API. Uses [`airbrake-go`](https://github.com/tobi/airbrake-go) behind the scenes. | -| [Papertrail](https://github.com/Sirupsen/logrus/blob/master/hooks/papertrail/papertrail.go) | Send errors to the Papertrail hosted logging service via UDP. | -| [Syslog](https://github.com/Sirupsen/logrus/blob/master/hooks/syslog/syslog.go) | Send errors to remote syslog server. Uses standard library `log/syslog` behind the scenes. | -| [BugSnag](https://github.com/Sirupsen/logrus/blob/master/hooks/bugsnag/bugsnag.go) | Send errors to the Bugsnag exception tracking service. | -| [Hiprus](https://github.com/nubo/hiprus) | Send errors to a channel in hipchat. | -| [Logrusly](https://github.com/sebest/logrusly) | Send logs to [Loggly](https://www.loggly.com/) | -| [Slackrus](https://github.com/johntdyer/slackrus) | Hook for Slack chat. | -| [Journalhook](https://github.com/wercker/journalhook) | Hook for logging to `systemd-journald` | -| [Graylog](https://github.com/gemnasium/logrus-hooks/tree/master/graylog) | Hook for logging to [Graylog](http://graylog2.org/) | - -#### Level logging - -Logrus has six logging levels: Debug, Info, Warning, Error, Fatal and Panic. - -```go -log.Debug("Useful debugging information.") -log.Info("Something noteworthy happened!") -log.Warn("You should probably take a look at this.") -log.Error("Something failed but I'm not quitting.") -// Calls os.Exit(1) after logging -log.Fatal("Bye.") -// Calls panic() after logging -log.Panic("I'm bailing.") -``` - -You can set the logging level on a `Logger`, then it will only log entries with -that severity or anything above it: - -```go -// Will log anything that is info or above (warn, error, fatal, panic). Default. -log.SetLevel(log.InfoLevel) -``` - -It may be useful to set `log.Level = logrus.DebugLevel` in a debug or verbose -environment if your application has that. - -#### Entries - -Besides the fields added with `WithField` or `WithFields` some fields are -automatically added to all logging events: - -1. `time`. The timestamp when the entry was created. -2. `msg`. The logging message passed to `{Info,Warn,Error,Fatal,Panic}` after - the `AddFields` call. E.g. `Failed to send event.` -3. `level`. The logging level. E.g. `info`. - -#### Environments - -Logrus has no notion of environment. - -If you wish for hooks and formatters to only be used in specific environments, -you should handle that yourself. For example, if your application has a global -variable `Environment`, which is a string representation of the environment you -could do: - -```go -import ( - log "github.com/Sirupsen/logrus" -) - -init() { - // do something here to set environment depending on an environment variable - // or command-line flag - if Environment == "production" { - log.SetFormatter(logrus.JSONFormatter) - } else { - // The TextFormatter is default, you don't actually have to do this. - log.SetFormatter(logrus.TextFormatter) - } -} -``` - -This configuration is how `logrus` was intended to be used, but JSON in -production is mostly only useful if you do log aggregation with tools like -Splunk or Logstash. - -#### Formatters - -The built-in logging formatters are: - -* `logrus.TextFormatter`. Logs the event in colors if stdout is a tty, otherwise - without colors. - * *Note:* to force colored output when there is no TTY, set the `ForceColors` - field to `true`. To force no colored output even if there is a TTY set the - `DisableColors` field to `true` -* `logrus.JSONFormatter`. Logs fields as JSON. -* `logrus_logstash.LogstashFormatter`. Logs fields as Logstash Events (http://logstash.net). - - ```go - logrus.SetFormatter(&logrus_logstash.LogstashFormatter{Type: “application_name"}) - ``` - -Third party logging formatters: - -* [`zalgo`](https://github.com/aybabtme/logzalgo): invoking the P͉̫o̳̼̊w̖͈̰͎e̬͔̭͂r͚̼̹̲ ̫͓͉̳͈ō̠͕͖̚f̝͍̠ ͕̲̞͖͑Z̖̫̤̫ͪa͉̬͈̗l͖͎g̳̥o̰̥̅!̣͔̲̻͊̄ ̙̘̦̹̦. - -You can define your formatter by implementing the `Formatter` interface, -requiring a `Format` method. `Format` takes an `*Entry`. `entry.Data` is a -`Fields` type (`map[string]interface{}`) with all your fields as well as the -default ones (see Entries section above): - -```go -type MyJSONFormatter struct { -} - -log.SetFormatter(new(MyJSONFormatter)) - -func (f *JSONFormatter) Format(entry *Entry) ([]byte, error) { - // Note this doesn't include Time, Level and Message which are available on - // the Entry. Consult `godoc` on information about those fields or read the - // source of the official loggers. - serialized, err := json.Marshal(entry.Data) - if err != nil { - return nil, fmt.Errorf("Failed to marshal fields to JSON, %v", err) - } - return append(serialized, '\n'), nil -} -``` - -#### Logger as an `io.Writer` - -Logrus can be transormed into an `io.Writer`. That writer is the end of an `io.Pipe` and it is your responsibility to close it. - -```go -w := logger.Writer() -defer w.Close() - -srv := http.Server{ - // create a stdlib log.Logger that writes to - // logrus.Logger. - ErrorLog: log.New(w, "", 0), -} -``` - -Each line written to that writer will be printed the usual way, using formatters -and hooks. The level for those entries is `info`. - -#### Rotation - -Log rotation is not provided with Logrus. Log rotation should be done by an -external program (like `logrotate(8)`) that can compress and delete old log -entries. It should not be a feature of the application-level logger. - - -[godoc]: https://godoc.org/github.com/Sirupsen/logrus diff --git a/Godeps/_workspace/src/github.com/docker/libcontainer/vendor/src/github.com/Sirupsen/logrus/entry.go b/Godeps/_workspace/src/github.com/docker/libcontainer/vendor/src/github.com/Sirupsen/logrus/entry.go deleted file mode 100644 index 17fe6f70..00000000 --- a/Godeps/_workspace/src/github.com/docker/libcontainer/vendor/src/github.com/Sirupsen/logrus/entry.go +++ /dev/null @@ -1,252 +0,0 @@ -package logrus - -import ( - "bytes" - "fmt" - "io" - "os" - "time" -) - -// An entry is the final or intermediate Logrus logging entry.

It works in concert with the Go source code generated - for .proto files by the protocol compiler. - - A summary of the properties of the protocol buffer interface - for a protocol buffer variable v: - - - Names are turned from camel_case to CamelCase for export. - - There are no methods on v to set fields; just treat - them as structure fields. - - There are getters that return a field's value if set, - and return the field's default value if unset. - The getters work even if the receiver is a nil message. - - The zero value for a struct is its correct initialization state. - All desired fields must be set before marshaling. - - A Reset() method will restore a protobuf struct to its zero state. - - Non-repeated fields are pointers to the values; nil means unset. - That is, optional or required field int32 f becomes F *int32. - - Repeated fields are slices. - - Helper functions are available to aid the setting of fields. - msg.Foo = proto.String("hello") // set field - - Constants are defined to hold the default values of all fields that - have them. They have the form Default_StructName_FieldName. - Because the getter methods handle defaulted values, - direct use of these constants should be rare. - - Enums are given type names and maps from names to values. - Enum values are prefixed by the enclosing message's name, or by the - enum's type name if it is a top-level enum. Enum types have a String - method, and a Enum method to assist in message construction. - - Nested messages, groups and enums have type names prefixed with the name of - the surrounding message type. - - Extensions are given descriptor names that start with E_, - followed by an underscore-delimited list of the nested messages - that contain it (if any) followed by the CamelCased name of the - extension field itself.

Netlink +is the interface a user-space program in linux uses to communicate with +the kernel. It can be used to add and remove interfaces, set ip addresses +and routes, and configure ipsec. Netlink communication requires elevated +privileges, so in most cases this code needs to be run as root. Since +low-level netlink messages are inscrutable at best, the library attempts +to provide an api that is loosely modeled on the CLI provied by iproute2. +Actions like `ip link add` will be accomplished via a similarly named +function like AddLink(). This library began its life as a fork of the +netlink functionality in +[docker/libcontainer](https://github.com/docker/libcontainer) but was +heavily rewritten to improve testability, performance, and to add new +functionality like ipsec xfrm handling. + +## Local Build and Test ## + +You can use go get command: + + go get github.com/vishvananda/netlink + +Testing dependencies: + + go get github.com/vishvananda/netns + +Testing (requires root): + + sudo -E go test github.com/vishvananda/netlink + +## Examples ## + +Add a new bridge and add eth1 into it: + +```go +package main + +import ( + "net" + "github.com/vishvananda/netlink" +) + +func main() { + la := netlink.NewLinkAttrs() + la.Name = "foo" + mybridge := &netlink.Bridge{la}} + _ := netlink.LinkAdd(mybridge) + eth1, _ := netlink.LinkByName("eth1") + netlink.LinkSetMaster(eth1, mybridge) +} + +``` +Note `NewLinkAttrs` constructor, it sets default values in structure. For now +it sets only `TxQLen` to `-1`, so kernel will set default by itself. If you're +using simple initialization(`LinkAttrs{Name: "foo"}`) `TxQLen` will be set to +`0` unless you specify it like `LinkAttrs{Name: "foo", TxQLen: 1000}`. + +Add a new ip address to loopback: + +```go +package main + +import ( + "net" + "github.com/vishvananda/netlink" +) + +func main() { + lo, _ := netlink.LinkByName("lo") + addr, _ := netlink.ParseAddr("169.254.169.254/32") + netlink.AddrAdd(lo, addr) +} + +``` + +## Future Work ## + +Many pieces of netlink are not yet fully supported in the high-level +interface. Aspects of virtually all of the high-level objects don't exist. +Many of the underlying primitives are there, so its a matter of putting +the right fields into the high-level objects and making sure that they +are serialized and deserialized correctly in the Add and List methods. + +There are also a few pieces of low level netlink functionality that still +need to be implemented. Routing rules are not in place and some of the +more advanced link types. Hopefully there is decent structure and testing +in place to make these fairly straightforward to add. diff --git a/Godeps/_workspace/src/github.com/vishvananda/netlink/addr.go b/Godeps/_workspace/src/github.com/vishvananda/netlink/addr.go new file mode 100644 index 00000000..9bbaf508 --- /dev/null +++ b/Godeps/_workspace/src/github.com/vishvananda/netlink/addr.go @@ -0,0 +1,43 @@ +package netlink + +import ( + "fmt" + "net" + "strings" +) + +// Addr represents an IP address from netlink.
