+GIT v1.5.3.7 Release Notes
+==========================
+
+Fixes since v1.5.3.6
+--------------------
+
+ * git-send-email added 8-bit contents to the payload without
+ marking it as 8-bit in a CTE header.
+
+ * "git-bundle create a.bndl HEAD" dereferenced the symref and
+ did not record the ref as 'HEAD'; this prevented a bundle
+ from being used as a normal source of git-clone.
+
+ * The code to reject nonsense command line of the form
+ "git-commit -a paths..." and "git-commit --interactive
+ paths..." were broken.
+
+ * Adding a signature that is not ASCII-only to an original
+ commit that is ASCII-only would make the result non-ASCII.
+ "git-format-patch -s" did not mark such a message correctly
+ with MIME encoding header.
+
+ * git-add sometimes did not mark the resulting index entry
+ stat-clean. This affected only cases when adding the
+ contents with the same length as the previously staged
+ contents, and the previous staging made the index entry
+ "racily clean".
+
+ * git-commit did not honor GIT_INDEX_FILE the user had in the
+ environment.
+
+ * When checking out a revision, git-checkout did not report where the
+ updated HEAD is if you happened to have a file called HEAD in the
+ work tree.
+
+ * "git-rev-list --objects" mishandled a tree that points at a
+ submodule.
+
+ * "git cvsimport" was not ready for packed refs that "git gc" can
+ produce and gave incorrect results.
+
+ * Many scripted Porcelains were confused when you happened to have a
+ file called "HEAD" in your work tree.
+
+Also it contains updates to the user manual and documentation.
GIT v1.5.4 Release Notes
========================
+Removal
+-------
+
+ * "git svnimport" was removed in favor of "git svn".
+
+
+Deprecation notices
+-------------------
+
+ * Next feature release of git (this change is scheduled for v1.5.5 but
+ it could slip) will by default install dashed form of commands
+ (e.g. "git-commit") outside of users' normal $PATH, and will install
+ only selected commands ("git" itself, and "gitk") in $PATH. This
+ implies:
+
+ - Using dashed form of git commands (e.g. "git-commit") from the
+ command line has been informally deprecated since early 2006, but
+ now it officially is, and will be removed in the future. Use
+ dashless form (e.g. "git commit") instead.
+
+ - Using dashed from from your scripts, without first prepending the
+ return value from "git --exec-path" to the scripts' PATH, has been
+ informally deprecated since early 2006, but now it officially is.
+
+ - Use of dashed form with "PATH=$(git --exec-path):$PATH; export
+ PATH" early in your script is not deprecated with this change.
+
+ Users are strongly encouraged to adjust their habits and scripts now
+ to prepare for this.
+
+ * The post-receive hook was introduced in March 2007 to supersede
+ post-update hook, primarily to overcome the command line length
+ limitation of the latter. Use of post-update hook will be deprecated
+ in future versions of git, perhaps in v1.5.5.
+
+ * "git lost-found" was deprecated in favor of "git fsck"'s --lost-found
+ option, and will be removed in the future.
+
+ * "git peek-remote" is deprecated, as "git ls-remote" was written in C
+ and works for all transports, and will be removed in the future.
+
+
Updates since v1.5.3
--------------------
* Comes with much improved gitk.
- * Comes with git-gui 0.9.0 with i18n.
+ * Comes with "git gui" 0.9.0 with i18n.
+
+ * progress display from many commands are a lot nicer to the eye.
+ Transfer commands show throughput data.
+
+ * many commands that pay attention to per-directory .gitignore now do
+ so lazily, which makes the usual case go much faster.
- * git-lost-found was deprecated in favor of git-fsck's --lost-found
- option.
+ * Output processing for '--pretty=format:<user format>' has been
+ optimized.
- * git-peek-remote is deprecated, as git-ls-remote was written in C and
- works for all transports.
+ * Rename detection of diff family, while detecting exact matches, has
+ been greatly optimized.
- * "progress display" from many commands are a lot nicer to the
- eye. Transfer commands show throughput data.
+ * Rename detection of diff family tries to make more naturally looking
+ pairing. Earlier if more than one identical rename sources were
+ found in the preimage, they were picked pretty much at random.
- * git-reset is now built-in and its output can be squelched with -q.
+ * "git reset" is now built-in and its output can be squelched with -q.
- * git-send-email can optionally talk over ssmtp and use SMTP-AUTH.
+ * "git send-email" can optionally talk over ssmtp and use SMTP-AUTH.
- * git-rebase learned --whitespace option.
+ * "git rebase" learned --whitespace option.
- * In git-rebase, when you decide not to replay a particular change
- after the command stopped with a conflict, you can say "git-rebase
+ * In "git rebase", when you decide not to replay a particular change
+ after the command stopped with a conflict, you can say "git rebase
--skip" without first running "git reset --hard", as the command now
runs it for you.
- * git-remote knows --mirror mode.
+ * "git merge" can call the "post-merge" hook.
- * git-merge can call the "post-merge" hook.
+ * "git pack-objects" can optionally run deltification with multiple
+ threads.
- * git-pack-objects can optionally run deltification with multiple threads.
-
- * git-archive can optionally substitute keywords in files marked with
+ * "git archive" can optionally substitute keywords in files marked with
export-subst attribute.
- * git-for-each-ref learned %(xxxdate:<dateformat>) syntax to
- show the various date fields in different formats.
+ * "git cherry-pick" made a misguided attempt to repeat the original
+ command line in the generated log message, when told to cherry-pick a
+ commit by naming a tag that points at it. It does not anymore.
- * git-gc --auto is a low-impact way to automatically run a
- variant of git-repack that does not lose unreferenced objects
- (read: safer than the usual one) after the user accumulates
- too many loose objects.
+ * "git for-each-ref" learned %(xxxdate:<dateformat>) syntax to show the
+ various date fields in different formats.
- * You need to explicitly set clean.requireForce to "false" to allow
- git-clean without -f to do any damage (lack of the configuration
- variable used to mean "do not require", but we now use the safer
- default).
+ * "git gc --auto" is a low-impact way to automatically run a variant of
+ "git repack" that does not lose unreferenced objects (read: safer
+ than the usual one) after the user accumulates too many loose
+ objects.
- * git-clean has been rewritten in C.
+ * You need to explicitly set clean.requireForce to "false" to allow
+ "git clean" without -f to do any damage (lack of the configuration
+ variable used to mean "do not require -f option to lose untracked
+ files", but we now use the safer default).
- * git-push has been rewritten in C.
+ * "git clean" has been rewritten in C.
- * git-push learned --dry-run option to show what would happen
- if a push is run.
+ * "git push" learned --dry-run option to show what would happen if a
+ push is run.
- * git-push does not update a tracking ref on the pushing side when the
+ * "git push" does not update a tracking ref on the local side when the
remote refused to update the corresponding ref.
- * git-push learned --mirror option. This is to push the local refs
+ * "git push" learned --mirror option. This is to push the local refs
one-to-one to the remote, and deletes refs from the remote that do
not exist anymore in the repository on the pushing side.
- * git-remote learned "rm" subcommand.
+ * "git remote" knows --mirror mode. This is to set up configuration to
+ push into a remote repository to store local branch heads to the same
+ branch on the remote side, and remove branch heads locally removed
+ from local repository at the same time. Suitable for pushing into a
+ back-up repository.
- * git-rebase --interactive mode can now work on detached HEAD.
+ * "git remote" learned "rm" subcommand.
- * git-cvsserver can be run via git-shell.
+ * "git rebase --interactive" mode can now work on detached HEAD.
- * git-am and git-rebase are far less verbose.
+ * "git cvsserver" can be run via "git shell".
- * git-pull learned to pass --[no-]ff option to underlying git-merge.
+ * "git am" and "git rebase" are far less verbose.
+
+ * "git pull" learned to pass --[no-]ff option to underlying "git
+ merge".
* Various Perforce importer updates.

- GUI implementations.
+ * "git log" learned --early-output option to help interactive GUI
+ implementations.
+
+ * "git bisect" learned "skip" action to mark untestable commits.
+
+ * "git format-patch" learned "format.numbered" configuration variable
+ to automatically turn --numbered option on when more than one commits
+ are formatted.
- * git-svnimport was removed in favor of git-svn.
+ * "git ls-files" learned "--exclude-standard" to use the canned set of
+ exclude files.
- * git-bisect learned "skip" action to mark untestable commits.
+ * "git rebase" now detaches head during its operation, so after a
+ successful "git rebase" operation, the reflog entry branch@{1} for
+ the current branch points at the commit before the rebase was
+ started.
- * git-format-patch learned "format.numbered" configuration variable
- to automatically turn --numbered option on when more than one
- commits are formatted.
+ * "git tag -a -f existing" begins the editor session using the existing
+ annotation message.
- * git-ls-files learned "--exclude-standard" to use the canned
- set of exclude files.
+ * "git tag -m one -m bar" (multiple -m options) behaves similarly to
+ "git commit"; the parameters to -m options are formatted as separate
+ paragraphs.
- * git-rebase now detaches head during its operation, so after a
- successful "git rebase" operation, the reflog entry branch@{1}
- for the current branch points at the commit before the rebase
- was started.
+ * "git cvsexportcommit" learned -w option to specify and switch to the
+ CVS working directory.
- * "git-tag -a -f existing" begins the editor session using the
- existing annotation message.
+ * "git checkout" from a subdirectory learned to use "../path" to allow
+ checking out a path outside the current directory without cd'ing up.

- without cd'ing up.
+ * "git merge-ours" is now built-in.
- * "git send-email --dry-run" shows full headers for easier
- diagnosis.
+ * "git svn" learned "info" and "show-externals" subcommands.
- * "git merge-ours" is built-in.
+ * "git svn" run from a subdirectory failed to read settings from the
+ .git/config.
- * "git svn" learned "info" subcommand.
+ * "git svn" learned --use-log-author option, which picks up more
+ descriptive name from From: and Signed-off-by: lines in the commit
+ message.
- * "git status" from a subdirectory now shows relative paths
- which makes copy-and-pasting for git-checkout/git-add/git-rm
- easier.
+ * "git status" from a subdirectory now shows relative paths which makes
+ copy-and-pasting for git-checkout/git-add/git-rm easier.
- * Output processing for '--pretty=format:<user format>' has
- been optimized.
+ * "git checkout" from and to detached HEAD leaves a bit more
+ information in the reflog.
- * Rename detection diff family, while detecting exact matches,
- has been greatly optimized.
+ * "git branch" learned --contains option, to show only branches that
+ can reach a given commit.
* Example update and post-receive hooks have been improved.
+ * "git push" can remove a corrupt ref at the remote site with the usual
+ ":ref" refspec.
+
* In addition there are quite a few internal clean-ups. Notably
- many fork/exec have been replaced with run-command API,
All of the fixes in v1.5.3 maintenance series are included in
this release, unless otherwise noted.
- * git-svn talking with the SVN over http will correctly quote branch
- and project names.
+These fixes are only in v1.5.4 and not backported to v1.5.3 maintenance
+series.
- * "git rev-list --objects A..B" choked when the lower boundary
- of the range involved a subproject. This fix is also queued
- for 'maint' (but not in there yet).
+ * "git svn" talking with the SVN over http will correctly quote branch
+ and project names.

+--get-color name default::
+
+ Find the color configured for `name` (e.g. `color.diff.new`) and

+ there is no color configured for `name`.

------------
+An example to use customized color from the configuration in your
+script:

+RESET=$(git config --get-color "" "reset")
+echo "${WS}your whitespace color or blue reverse${RESET}"

+\--rebase::
+ Instead of a merge, perform a rebase after fetching.
+ *NOTE:* This is a potentially _dangerous_ mode of operation.
+ It rewrites history, which does not bode well when you
+ published that history already. Do *not* use this option
+ unless you have read gitlink:git-rebase[1] carefully.
+
+\--no-rebase::
+ Override earlier \--rebase.
+
DEFAULT BEHAVIOUR
-----------------
Typing "git tag" without arguments, also lists all tags.
-m <msg>::
- Use the given tag message (instead of prompting)
+ Use the given tag message (instead of prompting).
+ If multiple `-m` options are given, there values are
+ concatenated as separate paragraphs.
-F <file>::
Take the tag message from the given file. Use '-' to

NOTE! A `--remove` flag does 'not' mean that subsequent filenames will
necessarily be removed: if the files still exist in your directory
structure, the index will be updated with their new status, not
-removed. The only thing `--remove` means is that update-cache will be
+removed. The only thing `--remove` means is that update-index will be
considering a removed file to be a valid thing, and if the file really
does not exist any more, it will update the index accordingly.

How to configure gitweb for your local system
---------------------------------------------
+See also "Build time configuration" section in INSTALL
+file for gitweb (in gitweb/INSTALL).
+
You can specify the following configuration variables when building GIT:
+ * GIT_BINDIR
+ Points out where to find git executable. You should set up it to
+ the place where git binary was installed (usually /usr/bin) if you
+ don't install git from sources together with gitweb. [Default: $(bindir)]
* GITWEB_SITENAME
- Shown in the title of all generated pages, defaults to the servers name.
+ Shown in the title of all generated pages, defaults to the server name
+ (SERVER_NAME CGI environment variable) if not set. [No default]
* GITWEB_PROJECTROOT
- The root directory for all projects shown by gitweb.
+ The root directory for all projects shown by gitweb. Must be set
+ correctly for gitweb to find repositories to display. See also
+ "Gitweb repositories" in INSTALL file for gitweb. [Default: /pub/git]
+ * GITWEB_PROJECT_MAXDEPTH
+ The filesystem traversing limit for getting projects list; the number
+ is taken as depth relative to the projectroot. It is used when
+ GITWEB_LIST is a directory (or is not set; then project root is used).
+ Is is meant to speed up project listing on large work trees by limiting
+ find depth. [Default: 2007]
* GITWEB_LIST
- points to a directory to scan for projects (defaults to project root)
- or to a file for explicit listing of projects.
+ Points to a directory to scan for projects (defaults to project root
+ if not set / if empty) or to a file with explicit listing of projects
+ (together with projects' ownership). See "Generating projects list
+ using gitweb" in INSTALL file for gitweb to find out how to generate
+ such file from scan of a directory. [No default, which means use root
+ directory for projects]
+ * GITWEB_EXPORT_OK
+ Show repository only if this file exists (in repository). Only
+ effective if this variable evaluates to true. [No default / Not set]
+ * GITWEB_STRICT_EXPORT
+ Only allow viewing of repositories also shown on the overview page.
+ This for example makes GITWEB_EXPORT_OK to decide if repository is
+ available and not only if it is shown. If GITWEB_LIST points to
+ file with list of project, only those repositories listed would be
+ available for gitweb. [No default]
* GITWEB_HOMETEXT
- points to an .html file which is included on the gitweb project
- overview page.
+ Points to an .html file which is included on the gitweb project
+ overview page ('projects_list' view), if it exists. Relative to
+ gitweb.cgi script. [Default: indextext.html]
+ * GITWEB_SITE_HEADER
+ Filename of html text to include at top of each page. Relative to
+ gitweb.cgi script. [No default]
+ * GITWEB_SITE_FOOTER
+ Filename of html text to include at bottom of each page. Relative to
+ gitweb.cgi script. [No default]
+ * GITWEB_HOME_LINK_STR
+ String of the home link on top of all pages, leading to $home_link
+ (usually main gitweb page, which means projects list). Used as first
+ part of gitweb view "breadcrumb trail": <home> / <project> / <view>.
+ [Default: projects]
+ * GITWEB_SITENAME
+ Name of your site or organization to appear in page titles. Set it
+ to something descriptive for clearer bookmarks etc. If not set
+ (if empty) gitweb uses "$SERVER_NAME Git", or "Untitled Git" if
+ SERVER_NAME CGI environment variable is not set (e.g. if running
+ gitweb as standalone script). [No default]
+ * GITWEB_BASE_URL
+ Git base URLs used for URL to where fetch project from, i.e. full
+ URL is "$git_base_url/$project". Shown on projects summary page.
+ Repository URL for project can be also configured per repository; this
+ takes precendence over URL composed from base URL and project name.
+ Note that you can setup multiple base URLs (for example one for
+ git:// protocol access, one for http:// access) from gitweb config
+ file. [No default]
* GITWEB_CSS
- Points to the location where you put gitweb.css on your web server.
+ Points to the location where you put gitweb.css on your web server
+ (or to be more generic URI of gitweb stylesheet). Relative to base
+ URI of gitweb. Note that you can setup multiple stylesheets from
+ gitweb config file. [Default: gitweb.css]
* GITWEB_LOGO
- Points to the location where you put git-logo.png on your web server.
+ Points to the location where you put git-logo.png on your web server
+ (or to be more generic URI of logo, 72x27 size, displayed in top right
+ corner of each gitweb page, and used as logo for Atom feed). Relative
+ to base URI of gitweb. [Default: git-logo.png]
+ * GITWEB_FAVICON
+ Points to the location where you put git-favicon.png on your web server
+ (or to be more generic URI of favicon, assumed to be image/png type;
+ web browsers that support favicons (website icons) may display them
+ in the browser's URL bar and next to site name in bookmarks). Relative
+ to base URI of gitweb. [Default: git-favicon.png]
* GITWEB_CONFIG
- This file will be loaded using 'require' and can be used to override any
- of the options above as well as some other options - see the top of
- 'gitweb.cgi' for their full list and description. If the environment
- $GITWEB_CONFIG is set when gitweb.cgi is executed the file in the
- environment variable will be loaded instead of the file
- specified when gitweb.cgi was created.
+ This Perl file will be loaded using 'do' and can be used to override any
+ of the options above as well as some other options -- see the "Runtime
+ gitweb configuration" section below, and top of 'gitweb.cgi' for their
+ full list and description. If the environment variable GITWEB_CONFIG
+ is set when gitweb.cgi is executed, then the file specified in the
+ environment variable will be loaded instead of the file specified
+ when gitweb.cgi was created. [Default: gitweb_config.perl]
Runtime gitweb configuration
You can adjust gitweb behaviour using the file specified in `GITWEB_CONFIG`
(defaults to 'gitweb_config.perl' in the same directory as the CGI).
-See the top of 'gitweb.cgi' for the list of variables and some description.
The most notable thing that is not configurable at compile time are the
-optional features, stored in the '%features' variable. You can find further
-description on how to reconfigure the default features setting in your
-`GITWEB_CONFIG` or per-project in `project.git/config` inside 'gitweb.cgi'.
+optional features, stored in the '%features' variable.
+
+Ultimate description on how to reconfigure the default features setting
+in your `GITWEB_CONFIG` or per-project in `project.git/config` can be found
+as comments inside 'gitweb.cgi'.
+
+See also "Gitweb config file" (with example of gitweb config file), and
+"Gitweb repositories" sections in INSTALL file for gitweb.
+
+
+Gitweb config file is [fragment] of perl code. You can set variables
+using "our $variable = value"; text from "#" character until the end
+of a line is ignored. See perlsyn(1) man page for details.
+
+Below there is list of vaiables which you might want to set in gitweb config.
+See the top of 'gitweb.cgi' for the full list of variables and their
+descriptions.
+
+Gitweb config file variables
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can set, among others, the following variables in gitweb config files:
+ * $GIT
+ Cure git executable to use. By default set to "$GIT_BINDIR/git", which
+ in turn is by default set to "$(bindir)/git". If you use git from binary
+ package, set this to "/usr/bin/git". This can just be "git" if your
+ webserver has a sensible PATH. If you have multiple git versions
+ installed it is / can be used to choose which one to use.
+ * $version
+ Gitweb version, set automatically when creating gitweb.cgi from
+ gitweb.perl. You might want to modify it if you are running modified
+ gitweb.
+ * $my_url, $my_uri
+ URL and absolute URL of gitweb script; you might need to set those
+ variables if you are using 'pathinfo' feature: see also below.
+ * $home_link
+ Target of the home link on top of all pages (the first part of view
+ "breadcrumbs"). By default set to absolute URI of a page; you might
+ need to set it up to [base] gitweb URI if you use 'pathinfo' feature
+ (alternative format of the URLs, with project name embedded directly
+ in the path part of URL).
+ * @stylesheets
+ List of URIs of stylesheets (relative to base URI of a page). You
+ might specify more than one stylesheet, for example use gitweb.css
+ as base, with site specific modifications in separate stylesheet
+ to make it easier to upgrade gitweb. You can add 'site' stylesheet
+ for example by using
+ push @stylesheets, "gitweb-site.css";
+ in gitweb config file.
+ * $logo_url, $logo_label
+ URI and label (title) of GIT logo link (or your site logo, if you choose
+ to use different logo image). By default they point to git homepage;
+ in the past they pointed to git documentation at www.kernel.org.
+ * $projects_list_description_width
+ The width (in characters) of the projects list "Description" column.
+ Longer descriptions will be cut (trying to cut at word boundary);
+ full description is available as 'title' attribute (usually shown on
+ mouseover). By default set to 25, which might be too small if you
+ use long project descriptions.
+ * @git_base_url_list
+ List of git base URLs used for URL to where fetch project from, shown
+ in project summary page. Full URL is "$git_base_url/$project".
+ You can setup multiple base URLs (for example one for git:// protocol
+ access, and one for http:// "dumb" protocol access). Note that per
+ repository configuration in 'cloneurl' file, or as values of gitweb.url
+ project config.
+ * $default_blob_plain_mimetype
+ Default mimetype for blob_plain (raw) view, if mimetype checking
+ doesn't result in some other type; by default 'text/plain'.
+ * $default_text_plain_charset
+ Default charset for text files. If not set, web serwer configuration
+ would be used.
+ * $mimetypes_file
+ File to use for (filename extension based) guessing of MIME types before
+ trying /etc/mime.types. Path, if relative, is taken currently as taken
+ relative to current git repositoy.
+ * $fallback_encoding
+ Gitweb assumes this charset if line contains non-UTF-8 characters.
+ Fallback decoding is used without error checking, so it can be even
+ 'utf-8'. Value mist be valid encodig; see Encoding::Supported(3pm) man
+ page for a list. By default 'latin1', aka. 'iso-8859-1'.
+ * @diff_opts
+ Rename detection options for git-diff and git-diff-tree. By default
+ ('-M'); set it to ('-C') or ('-C', '-C') to also detect copies, or
+ set it to () if you don't want to have renames detection.
+
+Per-repository gitweb configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can also configure individual repositories shown in gitweb by creating
+file in the GIT_DIR of git repository, or by setting some repo configuration
+variable (in GIT_DIR/config).
+
+You can use the following files in repository:
+ * README.html
+ A .html file (HTML fragment) which is included on the gitweb project
+ summary page inside <div> block element. You can use it for longer
+ description of a project, to provide links for example to projects
+ homepage, etc.
+ * description (or gitweb.description)
+ Short (shortened by default to 25 characters in the projects list page)
+ single line description of a project (of a repository). Plain text file;
+ HTML will be escaped. By default set to
+ Unnamed repository; edit this file to name it for gitweb.
+ from the template during creating repository. You can use
+ gitweb.description repo configuration variable, but the file takes
+ precendence.
+ * cloneurl (or multiple-valued gitweb.url)
+ File with repository URL (used for clone and fetch), one per line.
+ Displayed in the project summary page. You can use multiple-valued
+ gitweb.url repository configuration variable for that, but the file
+ takes precendence.
+ * various gitweb.* config variables (in config)
+ Read description of %feature hash for detailed list, and some
+ descriptions.
