+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

intrusive change.
+ - Merging branches that have a file in one and a directory in
+ another at the same path used to get quite confused. We
+ handle such a case a bit more carefully, even though that is
+ still left as a conflict for the user to sort out. This
+ will not be backported to 1.5.1.x series, as it is rather an
+ intrusive change.

--remove-section::
Remove the given section from the configuration file.
CVS clients cannot tag, branch or perform GIT merges.
+git-cvsserver maps GIT branches to CVS modules. This is very different
+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"]

------
+[[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::
+ git directory name, where all characters except for
+ alpha-numeric ones, `.`, and `-` are replaced with
+ `_` (this should make it easier to use the directory
+ name in a filename if wanted)
+%m::
+ CVS module/git head name
+%a::
+ access method (one of "ext" or "pserver")
+%u::
+ Name of the user running git-cvsserver.
+ If no name can be determined, the
+ numeric uid is used.

+================
+
+NAME
+----
+gitattributes - defining attributes per path
+
+SYNOPSIS
+--------
+.gitattributes
+
+
+DESCRIPTION
+-----------
+
+A `gitattributes` file is a simple text file that gives
+`attributes` to pathnames.
+
+Each line in `gitattributes` file is of form:
+
+ glob attr1 attr2 ...
+
+That is, a glob pattern followed by an attributes list,
+separated by whitespaces. When the glob pattern matches the
+path in question, the attributes listed on the line are given to
+the path.
+
+Each attribute can be in one of these states for a given path:
+
+Set::
+
+ The path has the attribute with special value "true";
+ this is specified by listing only the name of the
+ attribute in the attribute list.
+
+Unset::
+
+ The path has the attribute with special value "false";
+ this is specified by listing the name of the attribute
+ prefixed with a dash `-` in the attribute list.
+
+Set to a value::
+
+ The path has the attribute with specified string value;
+ this is specified by listing the name of the attribute
+ followed by an equal sign `=` and its value in the
+ attribute list.
+
+Unspecified::
+
+ No glob pattern matches the path, and nothing says if
+ the path has or does not have the attribute.
+
+When more than one glob pattern matches the path, a later line
+overrides an earlier line.
+
+When deciding what attributes are assigned to a path, git
+consults `$GIT_DIR/info/attributes` file (which has the highest
+precedence), `.gitattributes` file in the same directory as the
+path in question, and its parent directories (the further the
+directory that contains `.gitattributes` is from the path in
+question, the lower its precedence).
+
+Sometimes you would need to override an setting of an attribute
+for a path to `unspecified` state. This can be done by listing
+the name of the attribute prefixed with an exclamation point `!`.
+
+
+EFFECTS
+-------
+
+Certain operations by git can be influenced by assigning
+particular attributes to a path. Currently, three operations
+are attributes-aware.
+
+Checking-out and checking-in
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The attribute `crlf` affects how the contents stored in the
+repository are copied to the working tree files when commands
+such as `git checkout` and `git merge` run. It also affects how
+git stores the contents you prepare in the working tree in the
+repository upon `git add` and `git commit`.
+
+Set::
+
+ Setting the `crlf` attribute on a path is meant to mark
+ the path as a "text" file. 'core.autocrlf' conversion
+ takes place without guessing the content type by
+ inspection.
+
+Unset::
+
+ Unsetting the `crlf` attribute on a path is meant to
+ mark the path as a "binary" file. The path never goes
+ through line endings conversion upon checkin/checkout.
+
+Unspecified::
+
+ Unspecified `crlf` attribute tells git to apply the
+ `core.autocrlf` conversion when the file content looks
+ like text.
+
+Set to string value "input"::
+
+ This is similar to setting the attribute to `true`, but
+ also forces git to act as if `core.autocrlf` is set to
+ `input` for the path.
+
+Any other value set to `crlf` attribute is ignored and git acts
+as if the attribute is left unspecified.
+
+
+The `core.autocrlf` conversion
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If the configuration variable `core.autocrlf` is false, no
+conversion is done.
+
+When `core.autocrlf` is true, it means that the platform wants
+CRLF line endings for files in the working tree, and you want to
+convert them back to the normal LF line endings when checking
+in to the repository.
+
+When `core.autocrlf` is set to "input", line endings are
+converted to LF upon checkin, but there is no conversion done
+upon checkout.
+
+
+Generating diff text
+~~~~~~~~~~~~~~~~~~~~
+
+The attribute `diff` affects if `git diff` generates textual
+patch for the path or just says `Binary files differ`.
+
+Set::
+
+ A path to which the `diff` attribute is set is treated
+ as text, even when they contain byte values that
+ normally never appear in text files, such as NUL.
+
+Unset::
+
+ A path to which the `diff` attribute is unset will
+ generate `Binary files differ`.
+
+Unspecified::
+
+ A path to which the `diff` attribute is unspecified
+ first gets its contents inspected, and if it looks like
+ text, it is treated as text. Otherwise it would
+ generate `Binary files differ`.
+
+Any other value set to `diff` attribute is ignored and git acts
+as if the attribute is left unspecified.
+
+
+Performing a three-way merge
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The attribute `merge` affects how three versions of a file is
+merged when a file-level merge is necessary during `git merge`,
+and other programs such as `git revert` and `git cherry-pick`.
+
+Set::
+
+ Built-in 3-way merge driver is used to merge the
+ contents in a way similar to `merge` command of `RCS`
+ suite. This is suitable for ordinary text files.
+
+Unset::
+
+ Take the version from the current branch as the
+ tentative merge result, and declare that the merge has
+ conflicts. This is suitable for binary files that does
+ not have a well-defined merge semantics.
+
+Unspecified::
+
+ By default, this uses the same built-in 3-way merge
+ driver as is the case the `merge` attribute is set.
+ However, `merge.default` configuration variable can name
+ different merge driver to be used for paths to which the
+ `merge` attribute is unspecified.
+
+Any other string value::
+
+ 3-way merge is performed using the specified custom
+ merge driver. The built-in 3-way merge driver can be
+ explicitly specified by asking for "text" driver; the
+ built-in "take the current branch" driver can be
+ requested by "binary".
+
+
+Defining a custom merge driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The definition of a merge driver is done in `gitconfig` not
+`gitattributes` file, so strictly speaking this manual page is a
+wrong place to talk about it. However...
+
+To define a custom merge driver `filfre`, add a section to your
+`$GIT_DIR/config` file (or `$HOME/.gitconfig` file) like this:
+
+----------------------------------------------------------------
+[merge "filfre"]
+ name = feel-free merge driver
+ driver = filfre %O %A %B
+ recursive = binary
+----------------------------------------------------------------
+
+The `merge.*.name` variable gives the driver a human-readable
+name.
+
+The `merge.*.driver` variable's value is used to construct a
+command to run to merge ancestor's version (`%O`), current
+version (`%A`) and the other branches' version (`%B`). These
+three tokens are replaced with the names of temporary files that
+hold the contents of these versions when the command line is
+built.
+
+The merge driver is expected to leave the result of the merge in
+the file named with `%A` by overwriting it, and exit with zero
+status if it managed to merge them cleanly, or non-zero if there
+were conflicts.
+
+The `merge.*.recursive` variable specifies what other merge
+driver to use when the merge driver is called for an internal
+merge between common ancestors, when there are more than one.
+When left unspecified, the driver itself is used for both
+internal merge and the final merge.
+
+
+EXAMPLE
+-------
+
+If you have these three `gitattributes` file:
+
+----------------------------------------------------------------
+(in $GIT_DIR/info/attributes)
+
+a* foo !bar -baz
+
+(in .gitattributes)
+abc foo bar baz
+
+(in t/.gitattributes)
+ab* merge=filfre
+abc -foo -bar
+*.c frotz
+----------------------------------------------------------------
+
+the attributes given to path `t/abc` are computed as follows:
+
+1. By examining `t/.gitattributes` (which is in the same
+ diretory as the path in question), git finds that the first
+ line matches. `merge` attribute is set. It also finds that
+ the second line matches, and attributes `foo` and `bar`

+
+2. Then it examines `.gitattributes` (which is in the parent
+ directory), and finds that the first line matches, but
+ `t/.gitattributes` file already decided how `merge`, `foo`
+ and `bar` attributes should be given to this path, so it
+ leaves `foo` and `bar` unset. Attribute `baz` is set.
+
+3. Finally it examines `$GIT_DIR/info/gitattributes`. This file
+ is used to override the in-tree settings. The first line is
+ a match, and `foo` is set, `bar` is reverted to unspecified
+ state, and `baz` is unset.
+
+As the result, the attributes assignement to `t/abc` becomes:
+
+----------------------------------------------------------------
+foo set to true
+bar unspecified
+baz set to false
+merge set to string value "filfre"
+frotz unspecified

Note: don't forget to 'add' a file again if you modified it after the
first 'add' and before 'commit'. Otherwise only the previous added
state of that file will be committed. This is because git tracks
-content, so what you're really 'add'ing to the commit is the *content*
+content, so what you're really 'adding' to the commit is the *content*
of the file in the state it is in when you 'add' it.

+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
+tags from another local repository to this one, even if they
+aren't the committer/tagger of those objects. In a nut shell
+the info/new-commit-check directory is a Git repository whose
+objects/info/alternates file lists this repository and all other
+possible sources, and whose refs subdirectory contains symlinks
+to this repository's refs subdirectory, and to all other possible
+sources refs subdirectories. Yes, this means that you cannot
+use packed-refs in those repositories as they won't be resolved
+correctly.
