-GIT v1.5.1.1 Release Notes (draft)
+GIT v1.5.1.1 Release Notes
==========================
Fixes since v1.5.1
- The documentation for cvsimport has been majorly improved.
+ - "git-show-ref --exclude-existing" was documented.
+
* Bugfixes
+ - The implementation of -p option in "git cvsexportcommit" had
+ the meaning of -C (context reduction) option wrong, and
+ loosened the context requirements when it was told to be
+ strict.
+
+ - "git cvsserver" did not behave like the real cvsserver when
+ client side removed a file from the working tree without
+ doing anything else on the path. In such a case, it should
+ restore it from the checked out revision.
+
+ - "git fsck" issued an alarming error message on detached
+ HEAD. It is not an error since at least 1.5.0.
+
- "git send-email" produced of References header of unbounded length;
fixed this with line-folding.
- gitweb did not show type-changing patch correctly in the
blobdiff view.
-* Performance Tweaks
+ - git-svn did not error out with incorrect command line options.
+
+ - git-svn fell into an infinite loop when insanely long commit
+ message was found.
+
+ - git-svn dcommit and rebase was confused by patches that were
+ merged from another branch that is managed by git-svn.

+ spec (e.g. "branches = proj/branches/*:refs/remotes/origin/*")

+GIT v1.5.1.2 Release Notes
+==========================
+
+Fixes since v1.5.1.1
+--------------------
+
+* Bugfixes
+
+ - "git clone" over http from a repository that has lost the
+ loose refs by running "git pack-refs" were broken (a code to
+ deal with this was added to "git fetch" in v1.5.0, but it
+ was missing from "git clone").
+
+ - "git diff a/ b/" incorrectly fell in "diff between two
+ filesystem objects" codepath, when the user most likely
+ wanted to limit the extent of output to two tracked
+ directories.
+
+ - git-quiltimport had the same bug as we fixed for
+ git-applymbox in v1.5.1.1 -- it gave an alarming "did not
+ have any patch" message (but did not actually fail and was
+ harmless).
+
+ - various git-svn fixes.
+
+ - Sample update hook incorrectly always refused requests to
+ delete branches through push.
+
+ - git-blame on a very long working tree path had buffer
+ overrun problem.
+
+ - git-apply did not like to be fed two patches in a row that created
+ and then modified the same file.
+
+ - git-svn was confused when a non-project was stored directly under
+ trunk/, branches/ and tags/.
+
+ - git-svn wants the Error.pm module that was at least as new
+ as what we ship as part of git; install ours in our private
+ installation location if the one on the system is older.
+
+ - An earlier update to command line integer parameter parser was
+ botched and made 'update-index --cacheinfo' completely useless.
+
+
+* Documentation updates
+
+ - Various documentation updates from J. Bruce Fields, Frank
+ Lichtenheld, Alex Riesen and others. Andrew Ruder started a
+ war on undocumented options.
- "git bisect start" can optionally take a single bad commit and
zero or more good commits on the command line.
+ - "git shortlog" can optionally be told to wrap its output.
+
+ - "subtree" merge strategy allows another project to be merged in as
+ your subdirectory.
+
+ - "git format-patch" learned a new --subject-prefix=<string>
+ option, to override the built-in "[PATCH]".
+
* Updated behavior of existing commands.
- "git diff --stat" shows size of preimage and postimage blobs
the root commit). We used to refuse to operate without a
good and a bad commit.
+ - "git push", when pushing into more than one repository, does
+ not stop at the first error.
+
+ - "git archive" does not insist you to give --format parameter
+ anymore; it defaults to "tar".
+
* Builds
- git-p4import has never been installed; now there is an

+ - Merging branches that have a file in one and a directory in

+-b::
+ Show blank SHA-1 for boundary commits. This can also
+ be controlled via the `blame.blankboundary` config option.
+
+--root::
+ Do not treat root commits as boundaries. This can also be
+ controlled via the `blame.showroot` config option.
+
+--show-stats::
+ Include additional statistics at the end of blame output.
+
+-L n,m::
+ Annotate only the specified line range (lines count from 1).
+
+-l::
+ Show long rev (Default: off).
+
+-t::
+ Show raw timestamp (Default: off).
+
+-S <revs-file>::
+ Use revs from revs-file instead of calling gitlink:git-rev-list[1].
+
+-p, --porcelain::
+ Show in a format designed for machine consumption.
+
+--incremental::
+ Show the result incrementally in a format designed for
+ machine consumption.
+
+--contents <file>::
+ When <rev> is not specified, the command annotates the
+ changes starting backwards from the working tree copy.
+ This flag makes the command pretend as if the working
+ tree copy has the contents of he named file (specify
+ `-` to make the command read from the standard input).
+
+-M|<num>|::
+ Detect moving lines in the file as well. When a commit
+ moves a block of lines in a file (e.g. the original file
+ has A and then B, and the commit changes it to B and
+ then A), traditional 'blame' algorithm typically blames
+ the lines that were moved up (i.e. B) to the parent and
+ assigns blame to the lines that were moved down (i.e. A)
+ to the child commit. With this option, both groups of lines
+ are blamed on the parent.
+
+ <num> is optional but it is the lower bound on the number of
+ alphanumeric characters that git must detect as moving
+ within a file for it to associate those lines with the parent
+ commit.
+
+-C|<num>|::
+ In addition to `-M`, detect lines copied from other
+ files that were modified in the same commit. This is
+ useful when you reorganize your program and move code
+ around across files. When this option is given twice,
+ the command looks for copies from all other files in the
+ parent for the commit that creates the file in addition.
+
+ <num> is optional but it is the lower bound on the number of
+ alphanumeric characters that git must detect as moving
+ between files for it to associate those lines with the parent
+ commit.
+
+-h, --help::
+ Show help message.
the working copy are ignored; useful on broken filesystems like FAT.
See gitlink:git-update-index[1]. True by default.
+core.autocrlf::
+ If true, makes git convert `CRLF` at the end of lines in text files to
+ `LF` when reading from the filesystem, and convert in reverse when
+ writing to the filesystem. The variable can be set to
+ 'input', in which case the conversion happens only while
+ reading from the filesystem but files are written out with
+ `LF` at the end of lines. Currently, which paths to consider
+ "text" (i.e. be subjected to the autocrlf mechanism) is
+ decided purely based on the contents.
+
core.symlinks::
If false, symbolic links are checked out as small plain files that
contain the link text. gitlink:git-update-index[1] and

+ Path to a log file where the cvs server interface well... logs
various stuff. See gitlink:git-cvsserver[1].
+gitcvs.allbinary::
+ If true, all files are sent to the client in mode '-kb'. This
+ causes the client to treat all files as binary files which suppresses
+ any newline munging it otherwise might do. A work-around for the
+ fact that there is no way yet to set single files to mode '-kb'.
+
+gitcvs.dbname::
+ Database used by git-cvsserver to cache revision information
+ derived from the git repository. The exact meaning depends on the
+ used database driver, for SQLite (which is the default driver) this
+ is a filename. Supports variable substitution (see
+ gitlink:git-cvsserver[1] for details). May not contain semicolons (`;`).
+ Default: '%Ggitcvs.%m.sqlite'
+
+gitcvs.dbdriver::
+ Used Perl DBI driver. You can specify any available driver
+ for this here, but it might not work. git-cvsserver is tested
+ with 'DBD::SQLite', reported to work with 'DBD::Pg', and
+ reported *not* to work with 'DBD::mysql'. Experimental feature.
+ May not contain double colons (`:`). Default: 'SQLite'.
+ See gitlink:git-cvsserver[1].
+
+gitcvs.dbuser, gitcvs.dbpass::
+ Database user and password. Only useful if setting 'gitcvs.dbdriver',
+ since SQLite has no concept of database users and/or passwords.
+ 'gitcvs.dbuser' supports variable substitution (see
+ gitlink:git-cvsserver[1] for details).
+
+All gitcvs variables except for 'gitcvs.allbinary' can also specifed
+as 'gitcvs.<access_method>.<varname>' (where 'access_method' is one
+of "ext" and "pserver") to make them apply only for the given access
+method.
+
http.sslVerify::
Whether to verify the SSL certificate when fetching or pushing
over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
http.noEPSV::
A boolean which disables using of EPSV ftp command by curl.
- This can helpful with some "poor" ftp servers which doesn't

---dotest=<dir>::
+-d=<dir>, --dotest=<dir>::
Instead of `.dotest` directory, use <dir> as a working
area to store extracted patches.

THE PORCELAIN FORMAT
--------------------
When <paths> are given, this command does *not* switch
branches. It updates the named paths in the working tree from
-the index file (i.e. it runs `git-checkout-index -f -u`), or a
-named commit. In
-this case, `-f` and `-b` options are meaningless and giving
+the index file (i.e. it runs `git-checkout-index -f -u`), or
+from a named commit. In
+this case, the `-f` and `-b` options are meaningless and giving
either of them results in an error. <tree-ish> argument can be
used to specify a specific tree-ish (i.e. commit, tag or tree)
to update the index for the given paths before updating the
Quiet, supress feedback messages.
-f::
- Force a re-read of everything.
+ Proceed even if the index or the working tree differs
+ from HEAD. This is used to throw away local changes.
-b::
Create a new branch named <new_branch> and start it at
--track::
When -b is given and a branch is created off a remote branch,
- setup so that git-pull will automatically retrieve data from
- the remote branch.
+ set up configuration so that git-pull will automatically
+ retrieve data from the remote branch. Set the
+ branch.autosetupmerge configuration variable to true if you
+ want git-checkout and git-branch to always behave as if
+ '--track' were given.
--no-track::
When -b is given and a branch is created off a remote branch,
- force that git-pull will automatically retrieve data from
- the remote branch independent of the configuration settings.
+ set up configuration so that git-pull will not retrieve data
+ from the remote branch, ignoring the branch.autosetupmerge
+ configuration variable.
-l::
Create the new branch's ref log. This activates recording of
development branch), adding this information can be
useful.
--r|--replay::
+-r::
It used to be that the command defaulted to do `-x`
described above, and `-r` was to disable it. Now the
default is not to do `-x` so this option is a no-op.

CVS clients cannot tag, branch or perform GIT merges.

+from what most CVS users would expect since in CVS modules usually represent
+one or more directories.
+
INSTALLATION
------------
------
Note: you need to ensure each user that is going to invoke git-cvsserver has
-write access to the log file and to the git repository. When offering anon
-access via pserver, this means that the nobody user should have write access
-to at least the sqlite database at the root of the repository.
+write access to the log file and to the database (see
+<<dbbackend,Database Backend>>. If you want to offer write access over
+SSH, the users of course also need write access to the git repository itself.
+
+[[configaccessmethod]]
+All configuration variables can also be overriden for a specific method of
+access. Valid method names are "ext" (for SSH access) and "pserver". The
+following example configuration would disable pserver access while still
+allowing access over SSH.
+------
+ [gitcvs]
+ enabled=0
+
+ [gitcvs "ext"]
+ enabled=1
+------
--
3. On the client machine you need to set the following variables.
CVSROOT should be set as per normal, but the directory should point at the
cvs co -d project-master master
------
+[[dbbackend]]
+Database Backend
+----------------
+
+git-cvsserver uses one database per git head (i.e. CVS module) to
+store information about the repository for faster access. The
+database doesn't contain any persitent data and can be completly
+regenerated from the git repository at any time. The database
+needs to be updated (i.e. written to) after every commit.
+
+If the commit is done directly by using git (as opposed to
+using git-cvsserver) the update will need to happen on the
+next repository access by git-cvsserver, independent of
+access method and requested operation.
+
+That means that even if you offer only read access (e.g. by using
+the pserver method), git-cvsserver should have write access to
+the database to work reliably (otherwise you need to make sure
+that the database if up-to-date all the time git-cvsserver is run).
+
+By default it uses SQLite databases in the git directory, named
+`gitcvs.<module_name>.sqlite`. Note that the SQLite backend creates
+temporary files in the same directory as the database file on
+write so it might not be enough to grant the users using
+git-cvsserver write access to the database file without granting
+them write access to the directory, too.
+
+You can configure the database backend with the following
+configuration variables:
+
+Configuring database backend
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+git-cvsserver uses the Perl DBI module. Please also read
+its documentation if changing these variables, especially
+about `DBI->connect()`.
+
+gitcvs.dbname::
+ Database name. The exact meaning depends on the
+ used database driver, for SQLite this is a filename.
+ Supports variable substitution (see below). May
+ not contain semicolons (`;`).
+ Default: '%Ggitcvs.%m.sqlite'
+
+gitcvs.dbdriver::
+ Used DBI driver. You can specify any available driver
+ for this here, but it might not work. cvsserver is tested
+ with 'DBD::SQLite', reported to work with
+ 'DBD::Pg', and reported *not* to work with 'DBD::mysql'.
+ Please regard this as an experimental feature. May not
+ contain double colons (`:`).
+ Default: 'SQLite'
+
+gitcvs.dbuser::
+ Database user. Only useful if setting `dbdriver`, since
+ SQLite has no concept of database users. Supports variable
+ substitution (see below).
+
+gitcvs.dbpass::
+ Database password. Only useful if setting `dbdriver`, since
+ SQLite has no concept of database passwords.
+
+All variables can also be set per access method, see <<configaccessmethod,above>>.
+
+Variable substitution
+^^^^^^^^^^^^^^^^^^^^^
+In `dbdriver` and `dbuser` you can use the following variables:
+
+%G::
+ git directory name
+%g::

patches being generated, and any patch that matches is
ignored.
+--subject-prefix=<Subject-Prefix>::
+ Instead of the standard '[PATCH]' prefix in the subject

+ allows for useful naming of a patch series, and can be
+ combined with the --numbered option.
+
--suffix=.<sfx>::
Instead of using `.patch` as the suffix for generated
filenames, use specifed suffix. A common alternative is
message can later be searched for within all .keep files to
locate any which have outlived their usefulness.

+The --exclude-existing form is a filter that does the inverse, it shows the

Use of this utility is encouraged in favor of directly accessing files under

Do not print any results to stdout. When combined with '--verify' this
can be used to silently check if a reference exists.

+ (2) ignore if pattern is provided and does not head-match refname;
+ (3) warn if refname is not a well-formed refname and skip;

------------------------------------------------
-A freshly cloned repository contains a single branch head, named
-"master", and working directory is initialized to the state of
-the project referred to by "master".
+A freshly cloned repository contains a single branch head, by default
+named "master", with the working directory initialized to the state of
+the project referred to by that branch head.
Most projects also use <<def_tag,tags>>. Tags, like heads, are
references into the project's history, and can be listed using the
create a new branch <new> referencing <start-point>, and
check it out.
-It is also useful to know that the special symbol "HEAD" can always
-be used to refer to the current branch.
+The special symbol "HEAD" can always be used to refer to the current
+branch. In fact, git uses a file named "HEAD" in the .git directory to
+remember which branch is current:
+
+------------------------------------------------
+$ cat .git/HEAD
+ref: refs/heads/master
+------------------------------------------------
+
+[[detached-head]]
+Examining an old version without creating a new branch
+------------------------------------------------------
+
+The git-checkout command normally expects a branch head, but will also
+accept an arbitrary commit; for example, you can check out the commit
+referenced by a tag:
+
+------------------------------------------------
+$ git checkout v2.6.17
+Note: moving to "v2.6.17" which isn't a local branch
+If you want to create a new branch from this checkout, you may do so
+(now or later) by using -b with the checkout command again. Example:
+ git checkout -b <new_branch_name>
+HEAD is now at 427abfa... Linux v2.6.17
+------------------------------------------------
+
+The HEAD then refers to the SHA1 of the commit instead of to a branch,
+and git branch shows that you are no longer on a branch:
+
+------------------------------------------------
+$ cat .git/HEAD
+427abfa28afedffadfca9dd8b067eb6d36bac53f
+git branch
+* (no branch)
+ master
+------------------------------------------------
+
+In this case we say that the HEAD is "detached".
+
+This can be an easy way to check out a particular version without having
+to make up a name for a new branch. However, keep in mind that when you
+switch away from the (for example, by checking out something else), you
+can lose track of what the HEAD used to point to.

-------------------------------------------
(Either gitk or git-log may be useful for finding the commit.)
-Then check out a new branch at that commit, edit it, and rebase the rest of
-the series on top of it:
+Then check out that commit, edit it, and rebase the rest of the series

Git internals
=============
-There are two object abstractions: the "object database", and the
-"current directory cache" aka "index".
+Git depends on two fundamental abstractions: the "object database", and
+the "current directory cache" aka "index".
The Object Database
-------------------
determined at object creation time, and which identifies the format of
the object (i.e. how it is used, and how it can refer to other
objects). There are currently four different object types: "blob",
-"tree", "commit" and "tag".
+"tree", "commit", and "tag".
-A "blob" object cannot refer to any other object, and is, like the type
-implies, a pure storage object containing some user data. It is used to
-actually store the file data, i.e. a blob object is associated with some
-particular version of some file.
+A <<def_blob_object,"blob" object>> cannot refer to any other object,
+and is, as the name implies, a pure storage object containing some
+user data. It is used to actually store the file data, i.e. a blob
+object is associated with some particular version of some file.
-A "tree" object is an object that ties one or more "blob" objects into a
-directory structure. In addition, a tree object can refer to other tree
-objects, thus creating a directory hierarchy.
+A <<def_tree_object,"tree" object>> is an object that ties one or more
+"blob" objects into a directory structure. In addition, a tree object
+can refer to other tree objects, thus creating a directory hierarchy.
-A "commit" object ties such directory hierarchies together into
-a DAG of revisions - each "commit" is associated with exactly one tree
-(the directory hierarchy at the time of the commit). In addition, a
-"commit" refers to one or more "parent" commit objects that describe the
-history of how we arrived at that directory hierarchy.
+A <<def_commit_object,"commit" object>> ties such directory hierarchies
+together into a <<def_DAG,directed acyclic graph>> of revisions - each
+"commit" is associated with exactly one tree (the directory hierarchy at
+the time of the commit). In addition, a "commit" refers to one or more
+"parent" commit objects that describe the history of how we arrived at
+that directory hierarchy.
As a special case, a commit object with no parents is called the "root"
object, and is the point of an initial project commit. Each project
just going to confuse people. So aim for the notion of "one root object
per project", even if git itself does not enforce that.
-A "tag" object symbolically identifies and can be used to sign other
-objects. It contains the identifier and type of another object, a
-symbolic name (of course!) and, optionally, a signature.
+A <<def_tag_object,"tag" object>> symbolically identifies and can be
+used to sign other objects. It contains the identifier and type of
+another object, a symbolic name (of course!) and, optionally, a
+signature.
Regardless of object type, all objects share the following
characteristics: they are all deflated with zlib, and have a header

+Invoked as: update refname old-sha1 new-sha1
+
+This script is run by git-receive-pack once for each ref that the
+client is trying to modify. If we exit with a non-zero exit value
+then the update for that particular ref is denied, but updates for
+other refs in the same run of receive-pack may still be allowed.
+
+We are run after the objects have been uploaded, but before the
+ref is actually modified. We take advantage of that fact when we
+look for "new" commits and tags (the new objects won't show up in
+`rev-list --all`).
+
+This script loads and parses the content of the config file
+"users/$this_user.acl" from the $acl_branch commit of $acl_git ODB.
+The acl file is a git-config style file, but uses a slightly more
+restricted syntax as the Perl parser contained within this script
+is not nearly as permissive as git-config.
+
+Example:
+
+ [user]
+ committer = John Doe <john.doe@example.com>
+ committer = John R. Doe <john.doe@example.com>
+
+ [repository "acls"]
+ allow = heads/master
+ allow = CDUR for heads/jd/
+ allow = C for ^tags/v\\d+$
+
+For all new commit or tag objects the committer (or tagger) line
+within the object must exactly match one of the user.committer
+values listed in the acl file ("HEAD:users/$this_user.acl").
+
+For a branch to be modified an allow line within the matching
+repository section must be matched for both the refname and the
+opcode.
+
+Repository sections are matched on the basename of the repository
+(after removing the .git suffix).
+
+The opcode abbrevations are:
+
+ C: create new ref
+ D: delete existing ref
+ U: fast-forward existing ref (no commit loss)
+ R: rewind/rebase existing ref (commit loss)
+
+if no opcodes are listed before the "for" keyword then "U" (for
+fast-forward update only) is assumed as this is the most common
+usage.
+
+Refnames are matched by always assuming a prefix of "refs/".
+This hook forbids pushing or deleting anything not under "refs/".
+
+Refnames that start with ^ are Perl regular expressions, and the ^
+is kept as part of the regexp. \\ is needed to get just one \, so
+\\d expands to \d in Perl. The 3rd allow line above is an example.
+
+Refnames that don't start with ^ but that end with / are prefix
+matches (2nd allow line above); all other refnames are strict
+equality matches (1st allow line).
+
+Anything pushed to "heads/" (ok, really "refs/heads/") must be
+a commit. Tags are not permitted here.
+
+Anything pushed to "tags/" (err, really "refs/tags/") must be an
+annotated tag. Commits, blobs, trees, etc. are not permitted here.
+Annotated tag signatures aren't checked, nor are they required.
+
+The special subrepository of 'info/new-commit-check' can
+be created and used to allow users to push new commits and
