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. ↑ "a workspace can be synchronized with more than one LibreSource Synchronizer. As a limitation, the network must have tree topology." says LibreSource Synchronizer.
  3. ↑ As of version 2.5, "LibreSource is now released under GPL Version 2".
  4. ↑ RTC is not a distributed revision control system; but has some distributed feature that can be configured
  5. ↑ Various forks of the original Unix sources exist, only one of which is actively maintained
  6. ↑ 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.
  7. ↑ While some forks of SCCS are free software, others remain closed as parts of commercial Unix distributions.
  8. ↑ SVK allows Subversion to have Distributed branches.
  9. ↑ 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.
  10. ↑ 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.
  11. ↑ A Bazaar bundle is a summary diff, with sufficient extra information to preserve history.
  12. ↑ Snapshots with binary files. It's discussed to have binary changesets in future (darcs 3)
  13. ↑ 4 MB of which are sqlite3.c
  14. ↑ Mercurial revision numbers are local to a repository; they can differ from repository to repository depending on in which order merges are performed.
  15. ↑ 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.
  16. ↑ Veracity revision numbers are local to a repository; they can differ from repository to repository depending on in which order merges are performed.
  17. ↑ Evil twins are common.Evil Twins in SCM, Not Hollywood
  18. ↑ Atomic commit can be enabled for individual checkin's ClearCase 7.1.1 release notes.
  19. ↑ See FAQ
  20. ↑ darcs' patches each bear a unique identifier, impossible to merge twice the same patch in a repository (without destructively modifying history using "unsafe" commands).
  21. ↑ Although it stores (and shows by default) 8-bit filename. See FAQ
  22. ↑ Using Item Revision Attributes ("Working with Items" demo, covering user define attributes).
  23. ↑ 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.
  24. ↑ Controlled by the 'crnl-glob' setting ()
  25. ↑ 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.
  26. ↑ Since git-1.7.9 (see release notes). Older versions do not sign commits, only tags (see the -s option in git-tag(1) Manual page)
  27. ↑ UTF-8 filenames are supported as of version 1.7.10 (MSysGit release notes).
  28. ↑ 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.
  29. ↑ Integrity enabled change packages provide complete workflow and 21 CFR Part 11 compliant digital signatures against the item controlling the change package.
  30. ↑ 2009 SP5 added a feature to merge child development paths.
  31. ↑ Its possible to embed the action in a shell or Ant script.
  32. ↑ A merged is tracked by its workspace origin.
  33. ↑ Mercurial is in the process of being translated to at least Dutch and Chinese
  34. ↑ Support depends upon host OS and is well supported under Unix, but not Windows OSs, due to lack of host support. See
  35. ↑ It could be done via user level hooks
  36. ↑ 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.
  37. ↑ Through the procees behaviour components: Operation advisors and Operation participants. http://jazz.net/library/article/292
  38. ↑ While the source code of SCCS has been written to support internationalisation, only English message texts exist.
  39. ↑ StarTeam supports atomic commits as of version 2006
  40. ↑ 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 such as svk.
  41. ↑ Since SVN 1.8 subversion supports improved move-tracking on the client side. On the server-side it's not supported yet.
  42. ↑ New to SVN 1.5 <http://subversion.apache.org/docs/release-notes/1.5.html#merge-tracking>. A separate tool "svnmerge" <http://www.dellroad.org/svnmerge/> provides merge tracking for older versions.
  43. ↑ 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.
  44. ↑ Uses subversion server
  45. ↑ in Asian releases (v6.6a to v7.1a) and since version 7.2 in general
  46. ↑ Version change history is removed upon rename; old name not referenced.
  47. ↑ not implemented yet
  48. ↑ Can not be disabled in dynamic views.
  49. ↑ Using alias of the CVSROOT/modules file.
  50. ↑ CVS records executable bit when a file is added, but does not allow changing it later on.
  51. ↑ This is a GUI feature supported by TortoiseCVS and WinCVS both of which include/use CVSNT.
  52. ↑ Same as CVS, plus also the ability to have replicated repositories including 'shadow' repositories.
  53. ↑ Use the module/directory name or an alias created using CVSROOT/modules or CVSROOT/modules2 administration file.
  54. ↑ CVSNT supports this when the make/build tool used also supports it.
  55. ↑ Darcs can do sparse checkouts from explicit checkpoints on darcs-1 repositories, but not from darcs-2 ones
  56. ↑ Darcs can automatically detect #! scripts and make them executable on checkout.
  57. ↑ Using Sub Project functionality (Documentation Portfolio | User's Guide | Relating a Project or Stream to Other Objects).
  58. ↑ Checkouts can be nested with "fossil open --nested"
  59. ↑ The Git FAQ states that keyword expansion is not a good thing
  60. ↑ add -i and add -p, see git-add(1) Manual Page
  61. ↑ The Git FAQ explains why preserving modification time is considered harmful
  62. ↑ Configurable on server as a Project Option and on the client as a User Option.
  63. ↑ commit --interactive, see SVK::Command::Commit
  64. ↑ Through third-party tools such as Tortoise SVN.
  65. ↑ 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.
  66. ↑ 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
  67. ↑ Standalone Branch
  68. ↑ Shared Repository
  69. ↑ Standalone Branch
  70. ↑ Heavyweight Checkout and Lightweight Checkout
  71. ↑ rebase plugin
  72. ↑ darcs doesn't have named branches, local or not, branching is handled solely through repository cloning
  73. ↑ darcs send prepares a bundle of patches, defaults to sending it by mail but can send it to a file instead
  74. ↑ pull is fetch plus merge.
  75. ↑ copies are detected after the fact, much like renames
  76. ↑ Mercurial Bookmarks are similar to local branches.
  77. ↑ Through any of various means, place (to-be-immutable) file in an immutable directory prior to vcheckin.
  78. ↑ mv(1) or link(2) the immutable file from its origin immutable directory to its destination immutable directory prior to vcheckin.
  79. ↑ Through any of various means, copy the immutable file from its origin immutable directory to its destination immutable directory prior to vcheckin.
  80. ↑ You can also enable this as a central preference in the repository server control panel or configuration file
  81. ↑ Requires administrator privileges. You can 'rollback' a change using 'cvs update –e –j @commitid –j "@<commitid"' but the change and rollback evidence remains in the history
  82. ↑ yes – use TortoiseCVS or WinCVS to commit the change to the destination and select which specific files to keep
  83. ↑ bisect is also available for cvs which should work with CVSNT
  84. ↑ 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
  85. ↑ fossil stash supports multiple shelves with comments.
  86. ↑ git stash is a multi-level shelve, it's possible to shelve several change groups at the same time
  87. ↑ Only works on a local repository and only on revisions without children. The disapprove command might be an alternative.
  88. ↑ svk status lists differences between working copy and repository, not differences between two repositories
  89. ↑ SVN Bisect tool svn-bisect
  90. ↑ svn status lists differences between working copy and repository, not differences between two repositories
  91. ↑ locks are advisory, and can't be enforced on disconnected instances
  92. ↑ Any OS that support a Java Virtual Machine 1.5
  93. ↑ hgweb for single-repository access and hgwebdir for multiple repository access from a single HTTP address
