A new release of git,, has been uploaded, replacing as
the current version.

This is a new upstream release.  See also the package documentation in
/usr/share/doc/git-, along with the attached upstream release notes.

When compiled out of the box, the upstream git maintainers cater to older
cygwin releases, and intentionally disable certain features that have been
reported on their mailing list, even though they work with the latest
cygwin.  Therefore, this build turns those features back on.  However, it
means that this version does assume that you are not using FAT or FAT32 to
hold your repositories, since they do not store file permissions very

Git is popular version control system designed to handle very large
projects with speed and efficiency; it is used mainly for various open
source projects, most notably the Linux kernel.

Git falls in the category of distributed source code management tools,
similar to e.g. GNU Arch or Monotone (or BitKeeper in the proprietary
world). Every Git working directory is a full-fledged repository with full
revision tracking capabilities, not dependent on network access or a
central server.

    working tree was dirty and cannot fast forward.  It does

  - 'cvsexportcommit' does not lose yet-to-be-used message file.

    over 2GB long.

  - 'git apply --whitespace=strip' should not touch unmodified

  - 'git-mailinfo' choke when a logical header line was too long.

  - 'git show A..B' did not error out.  Negative ref ("not A" in
    this example) does not make sense for the purpose of the
    command, so now it errors out.

  - 'git fmt-merge-msg --file' without file parameter did not
    correctly error out.

  - 'git archimport' barfed upon encountering a commit without

  - Other formatting and spelling fixes.

GIT v1.5.0.2 Release Notes

Fixes since v1.5.0.1

* Bugfixes

  - Automated merge conflict handling when changes to symbolic
    links conflicted were completely broken.  The merge-resolve
    strategy created a regular file with conflict markers in it
    in place of the symbolic link.  The default strategy,
    merge-recursive was even more broken.  It removed the path
    that was pointed at by the symbolic link.  Both of these
    problems have been fixed.

  - 'git diff maint master next' did not correctly give combined
    diff across three trees.

  - 'git fast-import' portability fix for Solaris.

  - 'git show-ref --verify' without arguments did not error out
    but segfaulted.

  - 'git diff :tracked-file `pwd`/an-untracked-file' gave an extra
    slashes after a/ and b/.

  - 'git format-patch' produced too long filenames if the commit
    message had too long line at the beginning.

  - Running 'make all' and then without changing anything
    running 'make install' still rebuilt some files.  This
    was inconvenient when building as yourself and then
    installing as root (especially problematic when the source
    directory is on NFS and root is mapped to nobody).

  - 'git-rerere' failed to deal with two unconflicted paths that
    sorted next to each other.

  - 'git-rerere' attempted to open(2) a symlink and failed if
    there was a conflict.  Since a conflicting change to a
    symlink would not benefit from rerere anyway, the command
    now ignores conflicting changes to symlinks.

  - 'git-repack' did not like to pass more than 64 arguments
    internally to underlying 'rev-list' logic, which made it
    impossible to repack after accumulating many (small) packs
    in the repository.

  - 'git-diff' to review the combined diff during a conflicted
    merge were not reading the working tree version correctly
    when changes to a symbolic link conflicted.  It should have
    read the data using readlink(2) but read from the regular
    file the symbolic link pointed at.

  - 'git-remote' did not like period in a remote's name.

* Documentation updates

  - added and clarified core.bare, core.legacyheaders configurations.

  - updated "git-clone --depth" documentation.

* Assorted git-gui fixes.

GIT v1.5.0.1 Release Notes

Fixes since v1.5.0

* Documentation updates

  - Clarifications and corrections to 1.5.0 release notes.

  - The main documentation did not link to git-remote documentation.

  - Clarified introductory text of git-rebase documentation.

  - Converted remaining mentions of update-index on Porcelain
    documents to git-add/git-rm.

  - Some i18n.* configuration variables were incorrectly
    described as core.*; fixed.

* Bugfixes

  - git-add and git-update-index on a filesystem on which
    executable bits are unreliable incorrectly reused st_mode
    bits even when the path changed between symlink and regular

  - git-daemon marks the listening sockets with FD_CLOEXEC so
    that it won't be leaked into the children.

  - segfault from git-blame when the mandatory pathname
    parameter was missing was fixed; usage() message is given

  - git-rev-list did not read $GIT_DIR/config file, which means
    that did not honor i18n.logoutputencoding correctly.

* Tweaks

  - sliding mmap() inefficiently mmaped the same region of a
    packfile with an access pattern that used objects in the
    reverse order.  This has been made more efficient.

GIT v1.5.0 Release Notes

Old news

This section is for people who are upgrading from ancient
versions of git.  Although all of the changes in this section
happened before the current v1.4.4 release, they are summarized
here in the v1.5.0 release notes for people who skipped earlier

As of git v1.5.0 there are some optional features that changes
the repository to allow data to be stored and transferred more
efficiently.  These features are not enabled by default, as they
will make the repository unusable with older versions of git.
Specifically, the available options are:

 - There is a configuration variable core.legacyheaders that
   changes the format of loose objects so that they are more
   efficient to pack and to send out of the repository over git
   native protocol, since v1.4.2.  However, loose objects
   written in the new format cannot be read by git older than
   that version; people fetching from your repository using
   older clients over dumb transports (e.g. http) using older
   versions of git will also be affected.

 - Since v1.4.3, configuration repack.usedeltabaseoffset allows
   packfile to be created in more space efficient format, which
   cannot be read by git older than that version.

The above two are not enabled by default and you explicitly have
to ask for them, because these two features make repositories
unreadable by older versions of git, and in v1.5.0 we still do
not enable them by default for the same reason.  We will change
this default probably 1 year after 1.4.2's release, when it is
reasonable to expect everybody to have new enough version of

 - 'git pack-refs' appeared in v1.4.4; this command allows tags
   to be accessed much more efficiently than the traditional
   'one-file-per-tag' format.  Older git-native clients can
   still fetch from a repository that packed and pruned refs
   (the server side needs to run the up-to-date version of git),
   but older dumb transports cannot.  Packing of refs is done by
   an explicit user action, either by use of "git pack-refs
   --prune" command or by use of "git gc" command.

 - 'git -p' to paginate anything -- many commands do pagination
   by default on a tty.  Introduced between v1.4.1 and v1.4.2;
   this may surprise old timers.

 - 'git archive' superseded 'git tar-tree' in v1.4.3;

 - 'git cvsserver' was new invention in v1.3.0;

 - 'git repo-config', 'git grep', 'git rebase' and 'gitk' were
   seriously enhanced during v1.4.0 timeperiod.

 - 'gitweb' became part of git.git during v1.4.0 timeperiod and
   seriously modified since then.

 - reflog is an v1.4.0 invention.  This allows you to name a
   revision that a branch used to be at (e.g. "git diff
   master@{yesterday} master" allows you to see changes since
   yesterday's tip of the branch).

Updates in v1.5.0 since v1.4.4 series

* Index manipulation

 - git-add is to add contents to the index (aka "staging area"
   for the next commit), whether the file the contents happen to
   be is an existing one or a newly created one.

 - git-add without any argument does not add everything
   anymore.  Use 'git-add .' instead.  Also you can add
   otherwise ignored files with an -f option.

 - git-add tries to be more friendly to users by offering an
   interactive mode ("git-add -i").

 - git-commit <path> used to refuse to commit if <path> was
   different between HEAD and the index (i.e. update-index was
   used on it earlier).  This check was removed.

 - git-rm is much saner and safer.  It is used to remove paths
   from both the index file and the working tree, and makes sure
   you are not losing any local modification before doing so.

 - git-reset <tree> <paths>... can be used to revert index
   entries for selected paths.

 - git-update-index is much less visible.  Many suggestions to
  use the command in git output and documentation have now been
  replaced by simpler commands such as "git add" or "git rm".

* Repository layout and objects transfer

 - The data for origin repository is stored in the configuration
   file $GIT_DIR/config, not in $GIT_DIR/remotes/, for newly
   created clones.  The latter is still supported and there is
   no need to convert your existing repository if you are
   already comfortable with your workflow with the layout.

 - git-clone always uses what is known as "separate remote"
   layout for a newly created repository with a working tree.

   A repository with the separate remote layout starts with only
   one default branch, 'master', to be used for your own
   development.  Unlike the traditional layout that copied all
   the upstream branches into your branch namespace (while
   renaming their 'master' to your 'origin'), the new layout
   puts upstream branches into local "remote-tracking branches"
   with their own namespace. These can be referenced with names
   such as "origin/$upstream_branch_name" and are stored in
   .git/refs/remotes rather than .git/refs/heads where normal
   branches are stored.

   This layout keeps your own branch namespace less cluttered,
   avoids name collision with your upstream, makes it possible
   to automatically track new branches created at the remote
   after you clone from it, and makes it easier to interact with
   more than one remote repository (you can use "git remote" to
   add other repositories to track).  There might be some

   * 'git branch' does not show the remote tracking branches.
     It only lists your own branches.  Use '-r' option to view
     the tracking branches.

   * If you are forking off of a branch obtained from the
     upstream, you would have done something like 'git branch
     my-next next', because traditional layout dropped the
     tracking branch 'next' into your own branch namespace.
     With the separate remote layout, you say 'git branch next
     origin/next', which allows you to use the matching name
     'next' for your own branch.  It also allows you to track a
     remote other than 'origin' (i.e. where you initially cloned
     from) and fork off of a branch from there the same way
     (e.g. "git branch mingw j6t/master").

   Repositories initialized with the traditional layout continue
   to work.

 - New branches that appear on the origin side after a clone is
   made are also tracked automatically.  This is done with an
   wildcard refspec "refs/heads/*:refs/remotes/origin/*", which
   older git does not understand, so if you clone with 1.5.0,
   you would need to downgrade remote.*.fetch in the
   configuration file to specify each branch you are interested
   in individually if you plan to fetch into the repository with
   older versions of git (but why would you?).

 - Similarly, wildcard refspec "refs/heads/*:refs/remotes/me/*"
   can be given to "git-push" command to update the tracking
   branches that is used to track the repository you are pushing
   from on the remote side.

 - git-branch and git-show-branch know remote tracking branches
   (use the command line switch "-r" to list only tracked branches).

 - git-push can now be used to delete a remote branch or a tag.
   This requires the updated git on the remote side (use "git
   push <remote> :refs/heads/<branch>" to delete "branch").

 - git-push more aggressively keeps the transferred objects
   packed.  Earlier we recommended to monitor amount of loose
   objects and repack regularly, but you should repack when you
   accumulated too many small packs this way as well.  Updated
   git-count-objects helps you with this.

 - git-fetch also more aggressively keeps the transferred objects
   packed.  This behavior of git-push and git-fetch can be
   tweaked with a single configuration transfer.unpacklimit (but
   usually there should not be any need for a user to tweak it).

 - A new command, git-remote, can help you manage your remote
   tracking branch definitions.

 - You may need to specify explicit paths for upload-pack and/or
   receive-pack due to your ssh daemon configuration on the
   other end.  This can now be done via remote.*.uploadpack and
   remote.*.receivepack configuration.

* Bare repositories

 - Certain commands change their behavior in a bare repository
   (i.e. a repository without associated working tree).  We use
   a fairly conservative heuristic (if $GIT_DIR is ".git", or
   ends with "/.git", the repository is not bare) to decide if a
   repository is bare, but "core.bare" configuration variable
   can be used to override the heuristic when it misidentifies
   your repository.

 - git-fetch used to complain updating the current branch but
   this is now allowed for a bare repository.  So is the use of
   'git-branch -f' to update the current branch.

 - Porcelain-ish commands that require a working tree refuses to
   work in a bare repository.

* Reflog

 - Reflog records the history from the view point of the local
   repository. In other words, regardless of the real history,
   the reflog shows the history as seen by one particular
   repository (this enables you to ask "what was the current
   revision in _this_ repository, yesterday at 1pm?").  This
   facility is enabled by default for repositories with working
   trees, and can be accessed with the "branch@{time}" and
   "branch@{Nth}" notation.

 - "git show-branch" learned showing the reflog data with the
   new -g option.  "git log" has -s option to view reflog
   entries in a more verbose manner.

 - git-branch knows how to rename branches and moves existing
   reflog data from the old branch to the new one.

 - In addition to the reflog support in v1.4.4 series, HEAD
   reference maintains its own log.  "HEAD@{5.minutes.ago}"
   means the commit you were at 5 minutes ago, which takes
   branch switching into account.  If you want to know where the
   tip of your current branch was at 5 minutes ago, you need to
   explicitly say its name (e.g. "master@{5.minutes.ago}") or
   omit the refname altogether i.e. "@{5.minutes.ago}".

 - The commits referred to by reflog entries are now protected
   against pruning.  The new command "git reflog expire" can be
   used to truncate older reflog entries and entries that refer
   to commits that have been pruned away previously with older
   versions of git.

   Existing repositories that have been using reflog may get
   complaints from fsck-objects and may not be able to run
   git-repack, if you had run git-prune from older git; please
   run "git reflog expire --stale-fix --all" first to remove
   reflog entries that refer to commits that are no longer in
   the repository when that happens.

* Crufts removal

 - We used to say "old commits are retrievable using reflog and
   'master@{yesterday}' syntax as long as you haven't run
   git-prune".  We no longer have to say the latter half of the
   above sentence, as git-prune does not remove things reachable
   from reflog entries.

 - 'git-prune' by default does not remove _everything_
   unreachable, as there is a one-day grace period built-in.

 - There is a toplevel garbage collector script, 'git-gc', that
   runs periodic cleanup functions, including 'git-repack -a -d',
   'git-reflog expire', 'git-pack-refs --prune', and 'git-rerere

 - The output from fsck ("fsck-objects" is called just "fsck"
   now, but the old name continues to work) was needlessly
   alarming in that it warned missing objects that are reachable
   only from dangling objects.  This has been corrected and the
   output is much more useful.

* Detached HEAD

 - You can use 'git-checkout' to check out an arbitrary revision
   or a tag as well, instead of named branches.  This will
   dissociate your HEAD from the branch you are currently on.

   A typical use of this feature is to "look around".  E.g.

	$ git checkout v2.6.16
	... compile, test, etc.
	$ git checkout v2.6.17
	... compile, test, etc.

 - After detaching your HEAD, you can go back to an existing
   branch with usual "git checkout $branch".  Also you can
   start a new branch using "git checkout -b $newbranch" to
   start a new branch at that commit.

 - You can even pull from other repositories, make merges and
   commits while your HEAD is detached.  Also you can use "git
   reset" to jump to arbitrary commit, while still keeping your
   HEAD detached.

   Going back to attached state (i.e. on a particular branch) by
   "git checkout $branch" can lose the current stat you arrived
   in these ways, and "git checkout" refuses when the detached
   HEAD is not pointed by any existing ref (an existing branch,
   a remote tracking branch or a tag).  This safety can be
   overridden with "git checkout -f $branch".

* Packed refs

 - Repositories with hundreds of tags have been paying large
   overhead, both in storage and in runtime, due to the
   traditional one-ref-per-file format.  A new command,
   git-pack-refs, can be used to "pack" them in more efficient
   representation (you can let git-gc do this for you).

 - Clones and fetches over dumb transports are now aware of
   packed refs and can download from repositories that use

* Configuration

 - configuration related to color setting are consolidated under
   color.* namespace (older diff.color.*, status.color.* are
   still supported).

 - 'git-repo-config' command is accessible as 'git-config' now.

* Updated features

 - git-describe uses better criteria to pick a base ref.  It
   used to pick the one with the newest timestamp, but now it
   picks the one that is topologically the closest (that is,
   among ancestors of commit C, the ref T that has the shortest
   output from "git-rev-list T..C" is chosen).

 - git-describe gives the number of commits since the base ref
   between the refname and the hash suffix.  E.g. the commit one
   before v2.6.20-rc6 in the kernel repository is:


   which tells you that its object name begins with a21b069,
   v2.6.20-rc5 is an ancestor of it (meaning, the commit
   contains everything -rc5 has), and there are 306 commits
   since v2.6.20-rc5.

 - git-describe with --abbrev=0 can be used to show only the
   name of the base ref.

 - git-blame learned a new option, --incremental, that tells it
   to output the blames as they are assigned.  A sample script
   to use it is also included as contrib/blameview.

 - git-blame starts annotating from the working tree by default.

* Less external dependency

 - We no longer require the "merge" program from the RCS suite.
   All 3-way file-level merges are now done internally.

 - The original implementation of git-merge-recursive which was
   in Python has been removed; we have a C implementation of it

 - git-shortlog is no longer a Perl script.  It no longer
   requires output piped from git-log; it can accept revision
   parameters directly on the command line.

* I18n

 - We have always encouraged the commit message to be encoded in
   UTF-8, but the users are allowed to use legacy encoding as
   appropriate for their projects.  This will continue to be the
   case.  However, a non UTF-8 commit encoding _must_ be
   explicitly set with i18n.commitencoding in the repository
   where a commit is made; otherwise git-commit-tree will
   complain if the log message does not look like a valid UTF-8

 - The value of i18n.commitencoding in the originating
   repository is recorded in the commit object on the "encoding"
   header, if it is not UTF-8.  git-log and friends notice this,
   and reencodes the message to the log output encoding when
   displaying, if they are different.  The log output encoding
   is determined by "git log --encoding=<encoding>",
   i18n.logoutputencoding configuration, or i18n.commitencoding
   configuration, in the decreasing order of preference, and
   defaults to UTF-8.

 - Tools for e-mailed patch application now default to -u
   behavior; i.e. it always re-codes from the e-mailed encoding
   to the encoding specified with i18n.commitencoding.  This
   unfortunately forces projects that have happily been using a
   legacy encoding without setting i18n.commitencoding to set
   the configuration, but taken with other improvement, please
   excuse us for this very minor one-time inconvenience.

* e-mailed patches

 - See the above I18n section.

 - git-format-patch now enables --binary without being asked.
   git-am does _not_ default to it, as sending binary patch via
   e-mail is unusual and is harder to review than textual
   patches and it is prudent to require the person who is
   applying the patch to explicitly ask for it.

 - The default suffix for git-format-patch output is now ".patch",
   not ".txt".  This can be changed with --suffix=.txt option,
   or setting the config variable "format.suffix" to ".txt".

* Foreign SCM interfaces

  - git-svn now requires the Perl SVN:: libraries, the
    command-line backend was too slow and limited.

  - the 'commit' subcommand of git-svn has been renamed to
    'set-tree', and 'dcommit' is the recommended replacement for
    day-to-day work.

  - git fast-import backend.

* User support

 - Quite a lot of documentation updates.

 - Bash completion scripts have been updated heavily.

 - Better error messages for often used Porcelainish commands.

 - Git GUI.  This is a simple Tk based graphical interface for
   common Git operations.

* Sliding mmap

 - We used to assume that we can mmap the whole packfile while
   in use, but with a large project this consumes huge virtual
   memory space and truly huge ones would not fit in the
   userland address space on 32-bit platforms.  We now mmap huge
   packfile in pieces to avoid this problem.

* Shallow clones

 - There is a partial support for 'shallow' repositories that
   keeps only recent history.  A 'shallow clone' is created by
   specifying how deep that truncated history should be
   (e.g. "git clone --depth=5 git://some.where/repo.git").

   Currently a shallow repository has number of limitations:

   - Cloning and fetching _from_ a shallow clone are not
     supported (nor tested -- so they might work by accident but
     they are not expected to).

   - Pushing from nor into a shallow clone are not expected to

   - Merging inside a shallow repository would work as long as a
     merge base is found in the recent history, but otherwise it
     will be like merging unrelated histories and may result in
     huge conflicts.

   but this would be more than adequate for people who want to
   look at near the tip of a big project with a deep history and
   send patches in e-mail format.
