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. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, 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 + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. 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 PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +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. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Unlike submodules, subtrees do not need any special +constructions (like .gitmodule files or gitlinks) be present in +your repository, and do not force end-users of your +repository to do anything special or to understand how subtrees +work. A subtree is just a subdirectory that can be +committed to, branched, and merged along with your project in +any way you want. + +They are also not to be confused with using the subtree merge +strategy. The main difference is that, besides merging +the other project as a subdirectory, you can also extract the +entire history of a subdirectory from your project and make it +into a standalone project. Unlike the subtree merge strategy +you can alternate back and forth between these +two operations. If the standalone library gets updated, you can +automatically merge the changes into your project; if you +update the library inside your project, you can "split" the +changes back out again and merge them back into the library +project. + +For example, if a library you made for one application ends up being +useful elsewhere, you can extract its entire history and publish +that as its own git repository, without accidentally +intermingling the history of your application project. + +[TIP] +In order to keep your commit messages clean, we recommend that +people split their commits between the subtrees and the main +project as much as possible. That is, if you make a change that +affects both the library and the main application, commit it in +two pieces. That way, when you split the library commits out +later, their descriptions will still make sense. But if this +isn't important to you, it's not *necessary*. git subtree will +simply leave out the non-library-related parts of the commit +when it splits it out into the subproject later. + + +COMMANDS +-------- +add:: + Create the <prefix> subtree by importing its contents + from the given <refspec> or <repository> and remote <refspec>. + A new commit is created automatically, joining the imported + project's history with your own. With '--squash', imports + only a single commit from the subproject, rather than its + entire history. + +merge:: + Merge recent changes up to <commit> into the <prefix> + subtree. As with normal 'git merge', this doesn't + remove your own local changes; it just merges those + changes into the latest <commit>. With '--squash', + creates only one commit that contains all the changes, + rather than merging in the entire history. + + If you use '--squash', the merge direction doesn't + always have to be forward; you can use this command to + go back in time from v2.5 to v2.4, for example. If your + merge introduces a conflict, you can resolve it in the + usual ways. + +pull:: + Exactly like 'merge', but parallels 'git pull' in that + it fetches the given commit from the specified remote + repository. + +push:: + Does a 'split' (see above) using the <prefix> supplied + and then does a 'git push' to push the result to the + repository and refspec. This can be used to push your + subtree to different branches of the remote repository. + +split:: + Extract a new, synthetic project history from the + history of the <prefix> subtree. The new history + includes only the commits (including merges) that + affected <prefix>, and each of those commits now has the + contents of <prefix> at the root of the project instead + of in a subdirectory. Thus, the newly created history + is suitable for export as a separate git repository. + + After splitting successfully, a single commit id is + printed to stdout. This corresponds to the HEAD of the + newly created tree, which you can manipulate however you + want. + + Repeated splits of exactly the same history are + guaranteed to be identical (ie. to produce the same + commit ids). Because of this, if you add new commits + and then re-split, the new commits will be attached as + commits on top of the history you generated last time, + so 'git merge' and friends will work as expected. + + Note that if you use '--squash' when you merge, you + should usually not just '--rejoin' when you split. + + +OPTIONS +------- +-q:: +--quiet:: + Suppress unnecessary output messages on stderr. + +-d:: +--debug:: + Produce even more unnecessary output messages on stderr. + +-P <prefix>:: +--prefix=<prefix>:: + Specify the path in the repository to the subtree you + want to manipulate. This option is mandatory + for all commands. + +-m <message>:: +--message=<message>:: + This option is only valid for add, merge and pull (unsure). + Specify <message> as the commit message for the merge commit. + + +OPTIONS FOR add, merge, push, pull +---------------------------------- +--squash:: + This option is only valid for add, merge, push and pull + commands. + + Instead of merging the entire history from the subtree + project, produce only a single commit that contains all + the differences you want to merge, and then merge that + new commit into your project. + + Using this option helps to reduce log clutter. People + rarely want to see every change that happened between + v1.0 and v1.1 of the library they're using, since none of the + interim versions were ever included in their application. + + Using '--squash' also helps avoid problems when the same + subproject is included multiple times in the same + project, or is removed and then re-added. In such a + case, it doesn't make sense to combine the histories + anyway, since it's unclear which part of the history + belongs to which subtree. + + Furthermore, with '--squash', you can switch back and + forth between different versions of a subtree, rather + than strictly forward. 'git subtree merge --squash' + always adjusts the subtree to match the exactly + specified commit, even if getting to that commit would + require undoing some changes that were added earlier. + + Whether or not you use '--squash', changes made in your + local repository remain intact and can be later split + and send upstream to the subproject. + + +OPTIONS FOR split +----------------- +--annotate=<annotation>:: + This option is only valid for the split command. + + When generating synthetic history, add <annotation> as a + prefix to each commit message. Since we're creating new + commits with the same commit message, but possibly + different content, from the original commits, this can help + to differentiate them and avoid confusion. + + Whenever you split, you need to use the same + <annotation>, or else you don't have a guarantee that + the new re-created history will be identical to the old + one. That will prevent merging from working correctly. + git subtree tries to make it work anyway, particularly + if you use --rejoin, but it may not always be effective. + +-b <branch>:: +--branch=<branch>:: + This option is only valid for the split command. + + After generating the synthetic history, create a new + branch called <branch> that contains the new history. + This is suitable for immediate pushing upstream. + <branch> must not already exist. + +--ignore-joins:: + This option is only valid for the split command. + + If you use '--rejoin', git subtree attempts to optimize + its history reconstruction to generate only the new + commits since the last '--rejoin'. '--ignore-join' + disables this behaviour, forcing it to regenerate the + entire history. In a large project, this can take a + long time. + +--onto=<onto>:: + This option is only valid for the split command. + + If your subtree was originally imported using something + other than git subtree, its history may not match what + git subtree is expecting. In that case, you can specify + the commit id <onto> that corresponds to the first + revision of the subproject's history that was imported + into your project, and git subtree will attempt to build + its history from there. + + If you used 'git subtree add', you should never need + this option. + +--rejoin:: + This option is only valid for the split command. + + After splitting, merge the newly created synthetic + history back into your main project. That way, future + splits can search only the part of history that has + been added since the most recent --rejoin. + + If your split commits end up merged into the upstream + subproject, and then you want to get the latest upstream + version, this will allow git's merge algorithm to more + intelligently avoid conflicts (since it knows these + synthetic commits are already part of the upstream + repository). + + Unfortunately, using this option results in 'git log' + showing an extra copy of every new commit that was + created (the original, and the synthetic one). + + If you do all your merges with '--squash', don't use + '--rejoin' when you split, because you don't want the + subproject's history to be part of your project anyway. + + +EXAMPLE 1. Add command +---------------------- +Let's assume that you have a local repository that you would like +to add an external vendor library to. In this case we will add the +git-subtree repository as a subdirectory of your already existing +git-extensions repository in ~/git-extensions/: + + $ git subtree add --prefix=git-subtree --squash \ + git://github.com/apenwarr/git-subtree.git master + +'master' needs to be a valid remote ref and can be a different branch +name + +You can omit the --squash flag, but doing so will increase the number +of commits that are incldued in your local repository. + +We now have a ~/git-extensions/git-subtree directory containing code +from the master branch of git://github.com/apenwarr/git-subtree.git +in our git-extensions repository. + +EXAMPLE 2. Extract a subtree using commit, merge and pull +--------------------------------------------------------- +Let's use the repository for the git source code as an example. +First, get your own copy of the git.git repository: + + $ git clone git://git.kernel.org/pub/scm/git/git.git test-git + $ cd test-git + +gitweb (commit 1130ef3) was merged into git as of commit +0a8f4f0, after which it was no longer maintained separately. +But imagine it had been maintained separately, and we wanted to +extract git's changes to gitweb since that time, to share with +the upstream. You could do this: + + $ git subtree split --prefix=gitweb --annotate='(split) ' \ + 0a8f4f0^.. --onto=1130ef3 --rejoin \ + --branch gitweb-latest + $ gitk gitweb-latest + $ git push git@github.com:whatever/gitweb.git gitweb-latest:master + +(We use '0a8f4f0^..' because that means "all the changes from +0a8f4f0 to the current version, including 0a8f4f0 itself.") + +If gitweb had originally been merged using 'git subtree add' (or +a previous split had already been done with --rejoin specified) +then you can do all your splits without having to remember any +weird commit ids: + + $ git subtree split --prefix=gitweb --annotate='(split) ' --rejoin \ + --branch gitweb-latest2 + +And you can merge changes back in from the upstream project just +as easily: + + $ git subtree pull --prefix=gitweb \ + git@github.com:whatever/gitweb.git master + +Or, using '--squash', you can actually rewind to an earlier +version of gitweb: + + $ git subtree merge --prefix=gitweb --squash gitweb-latest~10 + +Then make some changes: + + $ date >gitweb/myfile + $ git add gitweb/myfile + $ git commit -m 'created myfile' + +And fast forward again: + + $ git subtree merge --prefix=gitweb --squash gitweb-latest + +And notice that your change is still intact: + + $ ls -l gitweb/myfile + +And you can split it out and look at your changes versus +the standard gitweb: + + git log gitweb-latest..$(git subtree split --prefix=gitweb) + +EXAMPLE 3. Extract a subtree using branch +----------------------------------------- +Suppose you have a source directory with many files and +subdirectories, and you want to extract the lib directory to its own +git project. Here's a short way to do it: + +First, make the new repository wherever you want: + + $ <go to the new location> + $ git init --bare + +Back in your original directory: + + $ git subtree split --prefix=lib --annotate="(split)" -b split + +Then push the new branch onto the new empty repository: + + $ git push <new-repo> split:master + + +AUTHOR +------ +Written by Avery Pennarun <apenwarr@gmail.com> + + +GIT +--- +Part of the linkgit:git[1] suite diff --git a/contrib/subtree/t/Makefile b/contrib/subtree/t/Makefile new file mode 100644 index 0000000000..c864810389 --- /dev/null +++ b/contrib/subtree/t/Makefile @@ -0,0 +1,69 @@ +# Run tests +# +# Copyright (c) 2005 Junio C Hamano +# + +-include ../../../config.mak.autogen +-include ../../../config.mak + +#GIT_TEST_OPTS=--verbose --debug +SHELL_PATH ?= $(SHELL) +PERL_PATH ?= /usr/bin/perl +TAR ?= $(TAR) +RM ?= rm -f +PROVE ?= prove +DEFAULT_TEST_TARGET ?= test + +# Shell quote;
