By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Lesser General Public License instead.) You can apply it to -your programs, too. - - 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 -this service 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. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -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 Program or any portion -of it, thus forming a work based on the Program, 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) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -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 Program, 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 Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) 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; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, 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 executable. However, as a -special exception, the source code 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. - -If distribution of executable or 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 counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program 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. - - 5. 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 Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program 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 to -this License. - - 7. 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 Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program 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 Program. - -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. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program 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. - - 9. The Free Software Foundation may publish revised and/or new versions -of the 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 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 Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10.

Such a -repo-specific config file may contain any of the repo-specific options -described above, except "repo.url" and "repo.path". Additionally, the "filter" -options are only acknowledged in repo-specific config files when -"enable-filter-overrides" is set to "1". - -Note: the "repo." prefix is dropped from the option names in repo-specific -config files, e.g. "repo.desc" becomes "desc". - - -FILTER API ----------- -By default, filters are separate processes that are executed each time they -are needed. Alternative technologies may be used by prefixing the filter -specification with the relevant string; available values are: - -'exec:':: - The default "one process per filter" mode. - - -Parameters are provided to filters as follows. - -about filter:: - This filter is given a single parameter: the filename of the source - file to filter. The filter can use the filename to determine (for - example) the type of syntax to follow when formatting the readme file. - The about text that is to be filtered is available on standard input - and the filtered text is expected on standard output. - -auth filter:: - The authentication filter receives 12 parameters: - - filter action, explained below, which specifies which action the - filter is called for - - http cookie - - http method - - http referer - - http path - - http https flag - - cgit repo - - cgit page - - cgit url - - cgit login url - When the filter action is "body", this filter must write to output the - HTML for displaying the login form, which POSTs to the login url. When - the filter action is "authenticate-cookie", this filter must validate - the http cookie and return a 0 if it is invalid or 1 if it is invalid, - in the exit code / close function. If the filter action is - "authenticate-post", this filter receives POST'd parameters on - standard input, and should write a complete CGI response, preferably - with a 302 redirect, and write to output one or more "Set-Cookie" - HTTP headers, each followed by a newline. - -commit filter:: - This filter is given no arguments. The commit message text that is to - be filtered is available on standard input and the filtered text is - expected on standard output. - -email filter:: - This filter is given two parameters: the email address of the relevant - author and a string indicating the originating page. The filter will - then receive the text string to format on standard input and is - expected to write to standard output the formatted text to be included - in the page. - -owner filter:: - This filter is given no arguments. The owner text is available on - standard input and the filter is expected to write to standard - output. The output is included in the Owner column. - -source filter:: - This filter is given a single parameter: the filename of the source - file to filter. The filter can use the filename to determine (for - example) the syntax highlighting mode. The contents of the source - file that is to be filtered is available on standard input and the - filtered contents is expected on standard output. - - -All filters are handed the following environment variables: - -- CGIT_REPO_URL (from repo.url) -- CGIT_REPO_NAME (from repo.name) -- CGIT_REPO_PATH (from repo.path) -- CGIT_REPO_OWNER (from repo.owner) -- CGIT_REPO_DEFBRANCH (from repo.defbranch) -- CGIT_REPO_SECTION (from repo.section) -- CGIT_REPO_CLONE_URL (from repo.clone-url) - -If a setting is not defined for a repository and the corresponding global -setting is also not defined (if applicable), then the corresponding -environment variable will be unset. - - -MACRO EXPANSION ---------------- -The following cgitrc options support a simple macro expansion feature, -where tokens prefixed with "$" are replaced with the value of a similarly -named environment variable: - -- cache-root -- include -- project-list -- scan-path - -Macro expansion will also happen on the content of $CGIT_CONFIG, if -defined. - -One usage of this feature is virtual hosting, which in its simplest form -can be accomplished by adding the following line to /etc/cgitrc: - - include=/etc/cgitrc.d/$HTTP_HOST - -The following options are expanded during request processing, and support -the environment variables defined in "FILTER API": - -- clone-url -- repo.clone-url - - -CACHE ------ - -All cache ttl values are in minutes. Negative ttl values indicate that a page -type will never expire, and thus the first time a URL is accessed, the result -will be cached indefinitely, even if the underlying git repository changes. -Conversely, when a ttl value is zero, the cache is disabled for that -particular page type, and the page type is never cached. - -SIGNATURES ----------- - -Cgit can host .asc signatures corresponding to various snapshot formats, -through use of git notes. For example, the following command may be used to -add a signature to a .tar.xz archive: - - git notes --ref=refs/notes/signatures/tar.xz add -C "$( - gpg --output - --armor --detach-sign cgit-1.1.tar.xz | - git hash-object -w --stdin - )" v1.1 - -If it is instead desirable to attach a signature of the underlying .tar, this -will be linked, as a special case, beside a .tar.* link that does not have its -own signature. For example, a signature of a tarball of the latest tag might -be added with a similar command: - - tag="$(git describe --abbrev=0)" - git notes --ref=refs/notes/signatures/tar add -C "$( - git archive --format tar --prefix "cgit-${tag#v}/" "$tag" | - gpg --output - --armor --detach-sign | - git hash-object -w --stdin - )" "$tag" - -Since git-archive(1) is expected to produce stable output between versions, -this allows one to generate a long-term signature of the contents of a given -tag. - -EXAMPLE CGITRC FILE -------------------- - -.... -# Enable caching of up to 1000 output entries -cache-size=1000 - - -# Specify some default clone urls using macro expansion -clone-url=git://foo.org/$CGIT_REPO_URL git@foo.org:$CGIT_REPO_URL - -# Specify the css url -css=/css/cgit.css - - -# Show owner on index page -enable-index-owner=1 - - -# Allow http transport git clone -enable-http-clone=1 - - -# Show extra links for each repository on the index page -enable-index-links=1 - - -# Enable blame page and create links to it from tree page -enable-blame=1 - - -# Enable ASCII art commit history graph on the log pages -enable-commit-graph=1 - - -# Show number of affected files per commit on the log pages -enable-log-filecount=1 - - -# Show number of added/removed lines per commit on the log pages -enable-log-linecount=1 - - -# Sort branches by date -branch-sort=age - - -# Add a cgit favicon -favicon=/favicon.ico - - -# Use a custom logo -logo=/img/mylogo.png - - -# Enable statistics per week, month and quarter -max-stats=quarter - - -# Set the title and heading of the repository index page -root-title=example.com git repositories - - -# Set a subheading for the repository index page -root-desc=tracking the foobar development - - -# Include some more info about example.com on the index page -root-readme=/var/www/htdocs/about.html - - -# Allow download of tar.gz, tar.bz2 and zip-files -snapshots=tar.gz tar.bz2 zip - - -## -## List of common mimetypes -## - -mimetype.gif=image/gif -mimetype.html=text/html -mimetype.jpg=image/jpeg -mimetype.jpeg=image/jpeg -mimetype.pdf=application/pdf -mimetype.png=image/png -mimetype.svg=image/svg+xml - - -# Highlight source code with python pygments-based highlighter -source-filter=/var/www/cgit/filters/syntax-highlighting.py - -# Format markdown, restructuredtext, manpages, text files, and html files -# through the right converters -about-filter=/var/www/cgit/filters/about-formatting.sh - -## -## Search for these files in the root of the default branch of repositories -## for coming up with the about page: -## -readme=:README.md -readme=:readme.md -readme=:README.mkd -readme=:readme.mkd -readme=:README.rst -readme=:readme.rst -readme=:README.html -readme=:readme.html -readme=:README.htm -readme=:readme.htm -readme=:README.txt -readme=:readme.txt -readme=:README -readme=:readme -readme=:INSTALL.md -readme=:install.md -readme=:INSTALL.mkd -readme=:install.mkd -readme=:INSTALL.rst -readme=:install.rst -readme=:INSTALL.html -readme=:install.html -readme=:INSTALL.htm -readme=:install.htm -readme=:INSTALL.txt -readme=:install.txt -readme=:INSTALL -readme=:install - - -## -## List of repositories. -## PS: Any repositories listed when section is unset will not be -## displayed under a section heading -## PPS: This list could be kept in a different file (e.g. '/etc/cgitrepos') -## and included like this: -## include=/etc/cgitrepos -## - - -repo.url=foo -repo.path=/pub/git/foo.git -repo.desc=the master foo repository -repo.owner=fooman@example.com -repo.readme=info/web/about.html - - -repo.url=bar -repo.path=/pub/git/bar.git -repo.desc=the bars for your foo -repo.owner=barman@example.com -repo.readme=info/web/about.html - - -# The next repositories will be displayed under the 'extras' heading -section=extras - - -repo.url=baz -repo.path=/pub/git/baz.git -repo.desc=a set of extensions for bar users - -repo.url=wiz -repo.path=/pub/git/wiz.git -repo.desc=the wizard of foo - - -# Add some mirrored repositories -section=mirrors - - -repo.url=git -repo.path=/pub/git/git.git -repo.desc=the dscm - - -repo.url=linux -repo.path=/pub/git/linux.git -repo.desc=the kernel - -# Disable adhoc downloads of this repo -repo.snapshots=0 - -# Disable line-counts for this repo -repo.enable-log-linecount=0 - -# Restrict the max statistics period for this repo -repo.max-stats=month -.... - - -BUGS ----- -Comments currently cannot appear on the same line as a setting; the comment -will be included as part of the value.
