Git is a free
distributed revision control, or software source codemanagement project with an emphasis on being fast. Git was initially created by Linus Torvaldsfor Linux kerneldevelopment.
Every Git working directory is a full-fledged repository with complete history and full revision tracking capabilities, not dependent on network access or a central server.
Several high-profile software projects now use Git for revision control [cite web |url=http://git.or.cz/gitwiki/GitProjects |title=Projects that use Git for their source code management |accessdate=2008-02-20] , most notably the
Linux kernel, X.org Server, Qt (toolkit), One Laptop per Child(OLPC) core development [cite web |url=http://wiki.laptop.org/go/Project_hosting |title=Project hosting |author=OLPC wiki |accessdate=2008-02-20] , Ruby on Railsweb framework [cite web |url=http://weblog.rubyonrails.org/2008/4/2/rails-is-moving-from-svn-to-git |title= "Rails is moving from SVN to Git" |accessdate=2008-04-03] , VLC, and Wine.
software maintenanceis overseen by Junio Hamano.
Linus Torvaldshas quipped about the name "", which is British Englishslang for a stupid or unpleasant person: [cite journal |url=http://www.infoworld.com/article/05/04/19/HNtorvaldswork_1.html |title=After controversy, Torvalds begins work on git |journal=InfoWorld |issn=0199-6649 |date=2005-04-19 |accessdate=2008-02-20] Cquote|I'm an egotistical bastard, and I name all my projects after myself. First Linux, now git. This self-deprecationis certainly tongue-in-cheek, insofar as Torvalds did not, in fact, name Linux after himself (see History of Linux).
The official Git wiki also gives a number of alternative explanations for the name. [ [http://git.or.cz/gitwiki/GitFaq#head-90fa13ebe170116f1586156e73b549cc2135b784 GitFaq: Why the 'git' name?] ]
Git's design was inspired by
BitKeeperand Monotone.

[cite mailing list |mailinglist=git |author=Linus Torvalds |url=http://marc.info/?l=git&m=114314642000462 |title=Re: Errors GITtifying GCC and Binutils |date=2006-03-23]
Git's design is a synthesis of Torvalds's experience maintaining a large distributed development project, his intimate knowledge of file system performance, and an urgent need to produce a working system in short order. (See the history section for details.) These influences led to the following implementation choices:
* Strong support for non-linear development. Git supports rapid branching and merging, and includes specific tools for visualizing and navigating a non-linear development history. A core assumption in Git is that a change will be merged more often than it is written, as it is passed around various reviewers.
* Distributed development. Like
Darcs, BitKeeper, Mercurial, SVK, Bazaar and Monotone, Git gives each developer a local copy of the entire development history, and changes are copied from one such repository to another. These changes are imported as additional development branches, and can be merged in the same way as a locally developed branch.
* Repositories can be published via HTTP, FTP, ssh,
rsync, or a Git protocol. Git also has a CVS server emulation, which enables the use of existing CVS clients and IDE plugins to access Git repositories.
* Subversion and svk repositories can be used directly with git-svn.
* Efficient handling of large projects. Torvalds has described Git as being very fast and scalable, [cite mailing list | author=Linus Torvalds |url=http://marc.info/?l=git&m=116128307511686 |title=Re: VCS comparison table |date=2006-10-19 |mailinglist=git] and performance tests done by

* Cryptographic authentication of history. The Git history is stored in such a way that the name of a particular revision (a "commit" in Git terms) depends upon the complete development history leading up to that commit. Once it is published, it is not possible to change the old versions without it being noticed. (Mercurial and Monotone also have this property.)
* Toolkit design. Git was designed as a set of programs written in C, and a number of shell scripts that provide wrappers around those programs. [cite mailing list
title=Re: VCS comparison table
date=2006-10-18, describing Git's script-oriented design] Although most of those scripts have been rewritten in C as part of an ongoing effort to port it to Microsoft Windows, the design remains, and it is easy to chain the components together to do other clever things. [cite web
date=2005-12-22, praising Git's scriptability]
* Pluggable merge strategies. As part of its toolkit design, Git has a well-defined model of an incomplete merge, and it has multiple algorithms for completing it, culminating in telling the user that it is unable to complete the merge automatically and manual editing is required.
* Garbage accumulates unless collected. Aborting operations or backing out changes will leave useless dangling objects in the database. These are generally a small fraction of the continuously growing history of wanted objects, but reclaiming the space using
git-gc --prunecan be slow. [cite web
title= Git User's Manual
One property of Git is that it snapshots directory trees of files. The earliest systems for tracking versions of source code, SCCS and RCS, worked on individual files and emphasized the space savings to be gained from
delta encodingthe (mostly similar) versions. Later revision control systems maintained this notion of a file having an identity across multiple revisions of a project.
Torvalds rejected this concept; [cite mailing list
title=Re: more git updates..
date=2005-04-10] consequently, Git does not explicitly record file revision relationships at any level below the source code tree. This has some significant consequences:
* It is slightly more expensive to examine the change history of a single file than the whole project. [cite mailing list
title=how to speed up "git log"?
date=2007-02-11] To obtain a history of changes affecting a given file, Git must walk the global history and then determine whether each change modified that file. This method of examining history does, however, let Git produce with equal efficiency a single history showing the changes to an arbitrary set of files. For example, a subdirectory of the source tree plus an associated global header file is a very common case.
* Renames are handled implicitly rather than explicitly. A common complaint with CVS is that it uses the name of a file to identify its revision history, so moving or renaming a file is not possible without either interrupting its history, or renaming the history and thereby making the history inaccurate. Most post-CVS revision control systems solve this by giving a file a unique long-lived name (a sort of inode number) that survives renaming. Git does not record such an identifier, and this is claimed as an advantage. [cite mailing list

Source codefiles are sometimes split or merged as well as simply renamed, [cite mailing list

title=Re: Errors GITtifying GCC and Binutils

git-blameto show code moved between source files] (Briefly, given a file in revision N, a file of the same name in revision N−1 is its default ancestor. However, when there is no like-named file in revision N−1, Git searches for a file that existed only in revision N−1 and is very similar to the new file.) However, it does require more CPU-intensive work every time history is reviewed, and a number of options to adjust the heuristics.
Additionally, people are sometimes upset by the storage model:
* Periodic explicit object packing. Git stores each newly created object as a separate file. Although individually compressed, this takes a great deal of space and is inefficient. This is solved by the use of "packs" that store a large number of objects in a single file (or network byte stream), delta-compressed among themselves. Packs are compressed using the heuristic that files with the same name are probably similar, but do not depend on it for correctness. Newly created objects (newly added history) are still stored singly, and periodic repacking is required to maintain space efficiency. Git does periodic repacking automatically but manual repacking is also possible with the git-gc command.
Git implements several merging strategies; a non-default can be selected at merge time: [cite web | author=Linus Torvalds | url=http://www.kernel.org/pub/software/scm/git/docs/git-merge.html | title=git-merge(1) | date=2007-07-18 ]
; resolve: the traditional
3-way mergealgorithm.; recursive: This is the default when pulling or merging one branch, and is a variant of the 3-way merge algorithm. "When there are more than one common ancestors that can be used for 3-way merge, it creates a merged tree of the common ancestors and uses that as the reference tree for the 3-way merge. This has been reported to result in fewer merge conflicts without causing mis-merges by tests done on actual merge commits taken from Linux 2.6 kernel development history. Additionally this can detect and handle merges involving renames." [cite web | author=Linus Torvalds | url=http://revctrl.org/CrissCrossMerge | title=CrissCrossMerge | date=2007-07-18 ] ; octopus: This is the default when merging more than two heads.
Git development began after many
Linux kerneldevelopers were forced to give up access to the proprietary BitKeeper system (see BitKeeper - Pricing change). The ability to use BitKeeper free of charge had been withdrawn by the copyright holder Larry McVoyafter he claimed Andrew Tridgellhad reverse engineered the BitKeeper protocols in violation of the BitKeeper license. At Linux.Conf.Au2005, Tridgell demonstrated during his keynote that the reverse engineering process he had used was simply to telnetto the appropriate port of a BitKeeper server and type "help". [Citation |author=Jonathan Corbet |journal=Linux Weekly News |url=http://lwn.net/Articles/132938/ |title=How Tridge reverse engineered BitKeeper |date=2005-04-20]
Torvalds wanted a distributed system that he could use like BitKeeper, but none of the available free systems met his needs, particularly his performance needs. From an e-mail he wrote on
April 7 2005while writing the first prototype: [cite mailing list |mailinglist=linux-kernel |author=Linus Torvalds |url=http://marc.info/?l=linux-kernel&m=111288700902396 |title=Re: Kernel SCM saga.. |date=2005-04-07]
However, the SCMs I've looked at make this hard. One of the things (the main thing, in fact) I've been working at is to make that process really "efficient". If it takes half a minute to apply a patch and remember the changeset boundary etc. (and quite frankly, that's "fast" for most SCMs around for a project the size of Linux), then a series of 250 emails (which is not unheard of at all when I sync with Andrew, for example) takes two hours. If one of the patches in the middle doesn't apply, things are bad bad bad.
Now, BK wasn't a speed demon either (actually, compared to everything else, BK "is" a speed deamon [sic] , often by one or two orders of magnitude), and took about 10–15 seconds per email when I merged with Andrew. HOWEVER, with BK that wasn't as big of an issue, since the BK<->BK merges were so easy, so I never had the slow email merges with any of the other main developers. So a patch-application-based SCM “merger” actually would need to be "faster" than BK is. Which is really really really hard.
So I'm writing some scripts to try to track things a whole lot faster. Initial indications are that I should be able to do it almost as quickly as I can just apply the patch, but quite frankly, I'm at most half done, and if I hit a snag maybe that's not true at all. Anyway, the reason I can do it quickly is that my scripts will "not" be an SCM, they'll be a very specific “log Linus' state” kind of thing. That will make the linear patch merge a lot more time-efficient, and thus possible.
(If a patch apply takes three seconds, even a big series of patches is not a problem: if I get notified within a minute or two that it failed half-way, that's fine, I can then just fix it up manually. That's why latency is critical—if I'd have to do things effectively “offline”, I'd by definition not be able to fix it up when problems happen).
Torvalds had several design criteria:
# Take CVS as an example of what "not" to do; if in doubt, make the exact opposite decision. To quote Torvalds, speaking somewhat tongue-in-cheek:
#: “For the first 10 years of kernel maintenance, we literally used tarballs and patches, which is a much superior source control management system than CVS is, but I did end up using CVS for 7 years at a commercial company " [presumably
Transmeta] " and I hate it with a passion. When I say I hate CVS with a passion, I have to also say that if there are any SVN (Subversion) users in the audience, you might want to leave. Because my hatred of CVS has meant that I see Subversion as being the most pointless project ever started. The slogan of Subversion for a while was ‘CVS done right’, or something like that, and if you start with that kind of slogan, there's nowhere you can go. There is no way to do CVS right.”cite video |people=Linus Torvalds |year=2007 |date=05-03 |url=http://www.youtube.com/watch?v=4XpnKHJAok8 |title=Google tech talk: Linus Torvalds on git |time=02:30 |accessdate=2007-05-16]
# Support a distributed, BitKeeper-like workflow
#: “BitKeeper was not only the first source control system that I ever felt was worth using at all, it was also the source control system that taught me why there's a point to them, and how you actually can do things. So Git in many ways, even though from a technical angle it is very very different from BitKeeper (which was another design goal, because I wanted to make it clear that it wasn't a BitKeeper clone), a lot of the flows we use with Git come directly from the flows we learned from BitKeeper.”
# Very strong safeguards against corruption, either accidental or malicious [cite mailing list |author=Linus Torvalds |authorlink=Linus Torvalds |mailinglist=git |date=2007-06-10 |title=Re: fatal: serious inflate inconsistency |url=http://marc.info/?l=git&m=118143549107708 A brief description of Git's data integrity design goals.]
# Very high performanceThe first three criteria eliminated every pre-existing version control system except for Monotone, and the fourth excluded everything.So, immediately after the 2.6.12-rc2 Linux kernel development release, he set out to write his own.

While strongly influenced by BitKeeper, Torvalds deliberately attempted to avoid conventional approaches, leading to a very novel design.

Like BitKeeper, Git does not use a centralized server. However, Git's primitives are not inherently a SCM system. Torvalds explains, [cite mailing list
title=Re: more git updates...
In many ways you can just see git as a filesystem — it's content-addressable, and it has a notion of versioning, but I really really designed it coming at the problem from the viewpoint of a "filesystem" person (hey, kernels is what I do), and I actually have absolutely "zero" interest in creating a traditional SCM system.:(Note that his opinion has changed since then.) [cite mailing list
title=Re: Errors GITtifying GCC and Binutils
Git has two
data structures, a mutable "index" that caches information about the working directory and the next revision to be committed, and an immutable, append-only "object database" containing four types of objects:
*A "blob" object is the content of a file. Blob objects have no names, timestamps, or other metadata.
* A "tree" object is the equivalent of a directory: it contains a list of filenames, each with some type bits and the name of a blob or tree object that is that file, symbolic link, or directory's contents. This object describes a snapshot of the source tree.
* A "commit" object links tree objects together into a history. It contains the name of a tree object (of the top-level source directory), a timestamp, a log message, and the names of zero or more parent commit objects.
* A "tag" object is a container that contains reference to another object and can hold additional meta-data related to another object. Most commonly it is used to store a digital signature of a commit object corresponding to a particular release of the data being tracked by Git.
The object database can hold any kind of object. An intermediate layer, the "index", serves as connection point between the object database and the working tree.
Each object is identified by a SHA-1 hash of its contents. Git computes the hash, and uses this value for the object's name. The object is put into a directory matching the first two characters of its hash. The rest of the hash is used as the file name for that object.
Git stores each revision of a file as a unique blob object. The relationships between the blobs can be found through examining the tree and commit objects. Newly added objects are stored in their entirety using
zlibcompression. This can consume a large amount of hard diskspace quickly, so objects can be combined into packs, which use delta compressionto save space, storing blobs as their changes relative to other blobs.
Git is primarily developed on
Linux, but can be used on other Unix-likeoperating systems including BSD, Solaris and Darwin. Git is extremely fast on POSIX-based systems such as Linux.
