Comparison of version-control software

The following is a comparison of version-control software. The following tables include general and technical information on notable version control and software configuration management (SCM) software. For SCM software not suitable for source code, see Comparison of open-source configuration-management software.

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.

General information

Table explanation

  • Repository model describes the relationship between various copies of the source code repository. In a client–server model, users access a master repository via a client; typically, their local machines hold only a working copy of a project tree. Changes in one working copy must be committed to the master repository before they are propagated to other users. In a distributed model, repositories act as peers, and users typically have a local repository with version history available, in addition to their working copies.
  • Concurrency model describes how changes to the working copy are managed to prevent simultaneous edits from causing nonsensical data in the repository. In a lock model, changes are disallowed until the user requests and receives an exclusive lock on the file from the master repository. In a merge model, users may freely edit files, but are informed of possible conflicts upon checking their changes into the repository, whereupon the version control system may merge changes on both sides, or let the user decide when conflicts arise. Distributed version control systems usually use a merge concurrency model.

Technical information

Table explanation

  • Software: The name of the application that is described.
  • Programming language: The coding language in which the application is being developed
  • Storage Method: Describes the form in which files are stored in the repository. A snapshot indicates that a committed file(s) is stored in its entirety—usually compressed. A changeset, in this context, indicates that a committed file(s) is stored in the form of a difference between either the previous version or the next.
  • Scope of change: Describes whether changes are recorded for individual files or for entire directory trees.
  • Revision IDs: are used internally to identify specific versions of files in the repository. Systems may use pseudorandom identifiers, content hashes of revisions, or filenames with sequential version numbers (namespace). With Integrated Difference, revisions are based on the Changesets themselves, which can describe changes to more than one file.
  • Network protocols: lists the protocols used for synchronization of changes.
  • Source code size: Gives the size of the source code in megabytes.

Features

Table explanation

  • Software: The name of the application that is described.
  • Atomic commits: refers to a guarantee that all changes are made, or that no change at all will be made.
  • File renames: describes whether a system allows files to be renamed while retaining their version history.
  • Merge file renames: describes whether a system can merge changes made to a file on one branch into the same file that has been renamed on another branch (or vice versa). If the same file has been renamed on both branches then there is a rename conflict that the user must resolve.
  • Symbolic links: describes whether a system allows revision control of symbolic links as with regular files. Versioning symbolic links is considered by some people a feature and some people a security breach (e.g., a symbolic link to /etc/passwd). Symbolic links are only supported on select platforms, depending on the software.
  • Pre-/post-event hooks: indicates the capability to trigger commands before or after an action, such as a commit, takes place.
  • Signed revisions: refers to integrated digital signing of revisions, in a format such as OpenPGP.
  • Merge tracking: describes whether a system remembers what changes have been merged between which branches and only merges the changes that are missing when merging one branch into another.
  • End of line conversions: describes whether a system can adapt the end of line characters for text files such that they match the end of line style for the operating system under which it is used. The granularity of control varies. Subversion, for example, can be configured to handle EOLs differently according to the file type, whereas Perforce converts all text files according to a single, per-client setting.
  • Tags: indicates if meaningful names can be given to specific revisions, regardless of whether these names are called tags or labels.
  • International support: indicates if the software has support for multiple language environments and operating system
  • Unicode filename support: indicates if the software has support for interoperations under file systems using different character encodings.
  • Supports large repos: Can the system handle repositories of around a gigabyte or larger effectively?

Advanced features

Table explanation

  • keyword expansion: supports automatic expansion of keywords such as file revision number.
  • interactive commits: interactive commits allow the user to cherrypick common lines of code used to anchor files (patch-hunks) that become part of a commit (leaving unselected changes as changes in the working copy), instead of having only a file-level granularity.
  • external references: embedding of foreign repositories in the source tree
  • partial checkout/clone: ability to check out or clone only a specified subdirectory from a repository.
  • permissions: tracks file permission bits in the revision history.
  • timestamp preservation: overwrites the last modified filesystem attribute with the commit time upon checkout.
  • custom automatic merge tool: automatic merging can be attempted by any tool of the user's choice (hopefully configurable on a per-file basis)
  • supported formats: either read/write support or read-only (conversion, potentially repeated)
  • shared build cache of derived objects: the ability to automatically substitute (wink-in) derived-objects that were built by other confederated clients that share exactly the same dependencies instead of rebuilding them locally

User interfaces

Table explanation

  • Software: The name of the application that is described.
  • Web Interface: Describes whether the software application contains a web interface. A web interface could allow the software to post diagnostics data to a website, or could even allow remote control of the software application.
  • GUIs: A GUI is a graphical user interface. If a software product features a GUI its functionality can be accessed through application windows as opposed to accessing functionality based upon typing commands at the command prompt such as a DOS interface.
  • Plug-ins: functionality is available through an Integrated Development Environment. Minimum functionality should be to list the revision state of a file and check in/check out files.

Notes
  1. In ClearCase, a trigger may be set to allow for the lock model, and this is done at many sites. However, ClearCase development usually takes place on private branches where each developer is given their own branch, so the lock vs. merge concurrency model doesn't matter as much. Code is merged back to the main branch once the developer is ready to deliver their code to the project.
  2. RTC is not a distributed revision control system; but has some distributed feature that can be configured
  3. Various forks of the original Unix sources exist, only one of which is actively maintained
  4. While it is possible for multiple users to edit the same version of a file concurrently, only one of them can write back the changes.
  5. While some forks of SCCS are free software, others remain closed as parts of commercial Unix distributions.
  6. In Subversion, a file attribute enables the lock model on per-file basis. This file attribute can be set automatically using file name wildcard expressions.
  7. Bazaar's critical modules are written in Pyrex. They are automatically translated to pure C; except for the patience sorting module, used in merge resolution, which is written directly in the C language.
  8. A Bazaar bundle is a summary diff, with sufficient extra information to preserve history.
  9. Snapshots with binary files. It's discussed to have binary changesets in future (darcs 3)
  10. 4 MB of which are sqlite3.c
  11. Mercurial revision numbers are local to a repository; they can differ from repository to repository depending on in which order merges are performed.
  12. A Monotone's revisions represent changesets and its manifests represent snapshots, each revision is linked to some manifest. But manifests are legacy constructs, they aren't kept in the database anymore and reconstructed on the fly if needed. The real work now happen in rosters which are hybrid snapshot/changeset structures.
  13. Evil twins are common.Evil Twins in SCM, Not Hollywood Archived 2013-10-16 at the Wayback Machine
  14. Atomic commit can be enabled for individual checkin's ClearCase 7.1.1 release notes.
  15. See FAQ
  16. darcs' patches each bear a unique identifier, impossible to merge twice the same patch in a repository (without destructively modifying history using "unsafe" commands).
  17. Although it stores (and shows by default) 8-bit filename. See FAQ
  18. Using Item Revision Attributes ("Working with Items" demo, covering user define attributes Archived 2016-03-04 at the Wayback Machine).
  19. In the sense that its messages and graphic interfaces have English only localization, though the software is certified running fine on various language operating systems.
  20. Controlled by the 'crnl-glob' setting ()
  21. Git does not explicitly track renames, because by design it does not track individual files. Renames and split of source files are detected after the fact, if the file content does not change dramatically.
  22. Since git-1.7.9 (see release notes Archived 2013-04-15 at Archive.today). Older versions do not sign commits, only tags (see the -s option in git-tag(1) Manual page)
  23. UTF-8 filenames are supported as of version 1.7.10 (MSysGit release notes).
  24. Git has some issues with very large repositories. See Section Better big-file support and Section Designing a faster index format in SoC 2012 Ideas.
  25. Integrity enabled change packages provide complete workflow and 21 CFR Part 11 compliant digital signatures against the item controlling the change package.
  26. 2009 SP5 added a feature to merge child development paths.
  27. Mercurial includes internationalization for more than 10 languages as of 2017.
  28. Support depends upon host OS and is well supported under Unix, but not Windows OSs, due to lack of host support. See
  29. It could be done via user level hooks
  30. Perforce will version-control symbolic links themselves, but will not recognise its own version-controlled views (local file trees), if you access them via symbolic links.
  31. Through the process behaviour components: Operation advisors and Operation participants. http://jazz.net/library/article/292
  32. While the source code of SCCS has been written to support internationalisation, only English message texts exist.
  33. StarTeam supports atomic commits as of version 2006
  34. Subversion can move a file and conserve its history, if and only if the target of the move is in the same Subversion repository as the source. Cross-repository moves require third-party tools.
  35. Since SVN 1.8 subversion supports improved move-tracking on the client side. On the server-side it's not supported yet.
  36. "Changeset Signing". Apache Subversion Mailing Lists. Retrieved 2016-08-05.
  37. New to SVN 1.5 <http://subversion.apache.org/docs/release-notes/1.5.html#merge-tracking>. A separate tool "svnmerge" <https://cracktower.blogspot.com/%5B%5D> provides merge tracking for older versions.
  38. In Subversion, tags are a special case of the more generic "cheap copy" concept of Subversion. Per convention, a tag is a copy into a directory named "tags". Because of this, even tags are versioned. See http://svnbook.red-bean.com/nightly/en/svn.branchmerge.tags.html for more information. The reason for partial support in the table is because Subversion's emulation of tags in this manner does not meet the requirement that the tag name can be used in place of any revision identifier wherever the user may be required to enter one. This column would be meaningless if the definition were to be loosened enough to encompass Subversion's approach as every version control system supports branching and would therefore support tags as well.
  39. in Asian releases (v6.6a to v7.1a) and since version 7.2 in general
  40. Version change history is removed upon rename; old name not referenced.
  41. not implemented yet
  42. Can not be disabled in dynamic views.
  43. Using alias of the CVSROOT/modules file.
  44. CVS records executable bit when a file is added, but does not allow changing it later on.
  45. This is a GUI feature supported by TortoiseCVS and WinCVS both of which include/use CVSNT.
  46. Same as CVS, plus also the ability to have replicated repositories including 'shadow' repositories.
  47. Use the module/directory name or an alias created using CVSROOT/modules or CVSROOT/modules2 administration file.
  48. CVSNT supports this when the make/build tool used also supports it.
  49. Darcs can do sparse checkouts from explicit checkpoints on darcs-1 repositories, but not from darcs-2 ones
  50. Darcs can automatically detect #! scripts and make them executable on checkout.
  51. Using Sub Project functionality (Documentation Portfolio | User's Guide | Relating a Project or Stream to Other Objects).
  52. Checkouts can be nested with "fossil open --nested"
  53. The Git FAQ states that keyword expansion is not a good thing
  54. add -i and add -p, see git-add(1) Manual Page
  55. The Git FAQ explains why preserving modification time is considered harmful
  56. Configurable on server as a Project Option and on the client as a User Option.
  57. Through third-party tools such as Tortoise SVN.
  58. SVN can not preserve file modification times. On request by the client, it can restore check-in time as last-modified time. Disabled by default.
  59. MIME type of the file must be detected as a "human-readable" MIME type, even if the merge tool can work with non-human-readable files
  60. Standalone Branch
  61. Shared Repository
  62. Standalone Branch
  63. Heavyweight Checkout and Lightweight Checkout
  64. rebase plugin
  65. darcs doesn't have named branches, local or not, branching is handled solely through repository cloning
  66. darcs send prepares a bundle of patches, defaults to sending it by mail but can send it to a file instead
  67. copies are detected after the fact, much like renames
  68. Mercurial Bookmarks are similar to local branches.
  69. SCCS has implicit locks, applied when checking out via edit, removed when creating a delta.
  70. Through any of various means, place (to-be-immutable) file in an immutable directory prior to vcheckin.
  71. mv(1) or link(2) the immutable file from its origin immutable directory to its destination immutable directory prior to vcheckin.
  72. Through any of various means, copy the immutable file from its origin immutable directory to its destination immutable directory prior to vcheckin.
  73. One can also enable this as a central preference in the repository server control panel or configuration file.
  74. Requires administrator privileges. One can 'roll back' a change using 'cvs update –e –j @commitid –j "@<commitid"' but the change and rollback evidence remain in the history.
  75. yes – use TortoiseCVS or WinCVS to commit the change to the destination and select which specific files to keep
  76. bisect is also available for cvs which should work with CVSNT
  77. darcs operate on patches not revision, cherrypicking simply consists in pulling a given patch from one repository to another one as long as the dependencies are fulfilled
  78. fossil stash supports multiple shelves with comments.
  79. git stash is a multi-level shelve, it's possible to shelve several change groups at the same time
  80. Only works on a local repository and only on revisions without children. The disapprove command might be an alternative.
  81. experimental in SVN 1.10 (release notes)
  82. SVN Bisect tool svn-bisect
  83. svn status lists differences between working copy and repository, not differences between two repositories
  84. hgweb for single-repository access and hgwebdir for multiple repository access from a single HTTP address
