+Git v1.7.10.1 Release Notes
+===========================
+
+Additions since v1.7.10
+-----------------------
+
+Localization message files for Danish and German have been added.
+
+
+Fixes since v1.7.10
+-------------------
+
+ * "git add -p" is not designed to deal with unmerged paths but did
+   not exclude them and tried to apply funny patches only to fail.
+
+ * "git blame" started missing quite a few changes from the origin
+   since we stopped using the diff minimalization by default in v1.7.2
+   era.
+
+ * When PATH contains an unreadable directory, alias expansion code
+   did not kick in, and failed with an error that said "git-subcmd"
+   was not found.
+
+ * "git clean -d -f" (not "-d -f -f") is supposed to protect nested
+   working trees of independent git repositories that exist in the
+   current project working tree from getting removed, but the
+   protection applied only to such working trees that are at the
+   top-level of the current project by mistake.
+
+ * "git commit --author=$name" did not tell the name that was being
+   recorded in the resulting commit to hooks, even though it does do
+   so when the end user overrode the authorship via the
+   "GIT_AUTHOR_NAME" environment variable.
+
+ * When "git commit --template F" errors out because the user did not
+   touch the message, it claimed that it aborts due to "empty
+   message", which was utterly wrong.
+
+ * The regexp configured with diff.wordregex was incorrectly reused
+   across files.
+
+ * An age-old corner case bug in combine diff (only triggered with -U0
+   and the hunk at the beginning of the file needs to be shown) has
+   been fixed.
+
+ * Rename detection logic used to match two empty files as renames
+   during merge-recursive, leading to unnatural mismerges.
+
+ * The parser in "fast-import" did not diagnose ":9" style references
+   that is not followed by required SP/LF as an error.
+
+ * When "git fetch" encounters repositories with too many references,
+   the command line of "fetch-pack" that is run by a helper
+   e.g. remote-curl, may fail to hold all of them. Now such an
+   internal invocation can feed the references through the standard
+   input of "fetch-pack".
+
+ * "git fetch" that recurses into submodules on demand did not check
+   if it needs to go into submodules when non branches (most notably,
+   tags) are fetched.
+
+ * "log -p --graph" used with "--stat" had a few formatting error.
+
+ * Running "notes merge --commit" failed to perform correctly when run
+   from any directory inside $GIT_DIR/.  When "notes merge" stops with
+   conflicts, $GIT_DIR/NOTES_MERGE_WORKTREE is the place a user edits
+   to resolve it.
+
+ * The 'push to upstream' implementation was broken in some corner
+   cases. "git push $there" without refspec, when the current branch
+   is set to push to a remote different from $there, used to push to
+   $there using the upstream information to a remote unreleated to
+   $there.
+
+ * Giving "--continue" to a conflicted "rebase -i" session skipped a
+   commit that only results in changes to submodules.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.10.2 Release Notes
+===========================
+
+Fixes since v1.7.10.1
+---------------------
+
+ * The test scaffolding for git-daemon was flaky.
+
+ * The test scaffolding for fast-import was flaky.
+
+ * The filesystem boundary was not correctly reported when .git directory
+   discovery stopped at a mount point.
+
+ * HTTP transport that requires authentication did not work correctly when
+   multiple connections are used simultaneously.
+
+ * In the older days, the header "Conflicts:" in "cherry-pick" and "merge"
+   was separated by a blank line from the list of paths that follow for
+   readability, but when "merge" was rewritten in C, we lost it by
+   mistake. Remove the newline from "cherry-pick" to make them match
+   again.
+
+ * The command line parser choked "git cherry-pick $name" when $name can
+   be both revision name and a pathname, even though $name can never be a
+   path in the context of the command.
+
+ * The "include.path" facility in the configuration mechanism added in
+   1.7.10 forgot to interpret "~/path" and "~user/path" as it should.
+
+ * "git config --rename-section" to rename an existing section into a
+   bogus one did not check the new name.
+
+ * The "diff --no-index" codepath used limited-length buffers, risking
+   pathnames getting truncated.  Update it to use the strbuf API.
+
+ * The report from "git fetch" said "new branch" even for a non branch
+   ref.
+
+ * The http-backend (the server side of the smart http transfer) used
+   to overwrite GIT_COMMITTER_NAME and GIT_COMMITTER_EMAIL with the
+   value obtained from REMOTE_USER unconditionally, making it
+   impossible for the server side site-specific customization to use
+   different identity sources to affect the names logged. It now uses
+   REMOTE_USER only as a fallback value.
+
+ * "log --graph" was not very friendly with "--stat" option and its
+   output had line breaks at wrong places.
+
+ * Octopus merge strategy did not reduce heads that are recorded in the
+   final commit correctly.
+
+ * "git push" over smart-http lost progress output a few releases ago;
+   this release resurrects it.
+
+ * The insn sheet given by "rebase -i" did not make it clear that the
+   insn lines can be re-ordered to affect the order of the commits in
+   the resulting history.
+
+ * A contrib script "rerere-train" did not work out of the box unless
+   user futzed with her $PATH.
+
+ * The i18n of error message "git stash save" was not properly done.
+
+ * "git submodule" used a sed script that some platforms mishandled.
+
+ * When using a Perl script on a system where "perl" found on user's
+   $PATH could be ancient or otherwise broken, we allow builders to
+   specify the path to a good copy of Perl with $PERL_PATH.  The
+   gitweb test forgot to use that Perl when running its test.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.10 Release Notes
+=========================
+
+Compatibility Notes
+-------------------
+
+ * From this release on, the "git merge" command in an interactive
+   session will start an editor when it automatically resolves the
+   merge for the user to explain the resulting commit, just like the
+   "git commit" command does when it wasn't given a commit message.
+
+   If you have a script that runs "git merge" and keeps its standard
+   input and output attached to the user's terminal, and if you do not
+   want the user to explain the resulting merge commits, you can
+   export GIT_MERGE_AUTOEDIT environment variable set to "no", like
+   this:
+
+	#!/bin/sh
+	GIT_MERGE_AUTOEDIT=no
+	export GIT_MERGE_AUTOEDIT
+
+   to disable this behavior (if you want your users to explain their
+   merge commits, you do not have to do anything).  Alternatively, you
+   can give the "--no-edit" option to individual invocations of the
+   "git merge" command if you know everybody who uses your script has
+   Git v1.7.8 or newer.
+
+ * The "--binary/-b" options to "git am" have been a no-op for quite a
+   while and were deprecated in mid 2008 (v1.6.0).  When you give these
+   options to "git am", it will now warn and ask you not to use them.
+
+ * When you do not tell which branches and tags to push to the "git
+   push" command in any way, the command used "matching refs" rule to
+   update remote branches and tags with branches and tags with the
+   same name you locally have.  In future versions of Git, this will
+   change to push out only your current branch according to either the
+   "upstream" or the "current" rule.  Although "upstream" may be more
+   powerful once the user understands Git better, the semantics
+   "current" gives is simpler and easier to understand for beginners
+   and may be a safer and better default option.  We haven't decided
+   yet which one to switch to.
+
+
+Updates since v1.7.9
+--------------------
+
+UI, Workflows & Features
+
+ * various "gitk" updates.
+   - show the path to the top level directory in the window title
+   - update preference edit dialog
+   - display file list correctly when directories are given on command line
+   - make "git-describe" output in the log message into a clickable link
+   - avoid matching the UNIX timestamp part when searching all fields
+   - give preference to symbolic font names like sans & monospace
+   - allow comparing two commits using a mark
+   - "gitk" honors log.showroot configuration.
+
+ * Teams for localizing the messages from the Porcelain layer of
+   commands are starting to form, thanks to Jiang Xin who volunteered
+   to be the localization coordinator.  Translated messages for
+   simplified Chinese, Swedish and Portuguese are available.
+
+ * The configuration mechanism learned an "include" facility; an
+   assignment to the include.path pseudo-variable causes the named
+   file to be included in-place when Git looks up configuration
+   variables.
+
+ * A content filter (clean/smudge) used to be just a way to make the
+   recorded contents "more useful", and allowed to fail; a filter can
+   now optionally be marked as "required".
+
+ * Options whose names begin with "--no-" (e.g. the "--no-verify"
+   option of the "git commit" command) can be negated by omitting
+   "no-" from its name, e.g. "git commit --verify".
+
+ * "git am" learned to pass "-b" option to underlying "git mailinfo", so
+   that a bracketed string other than "PATCH" at the beginning can be kept.
+
+ * "git clone" learned "--single-branch" option to limit cloning to a
+   single branch (surprise!); tags that do not point into the history
+   of the branch are not fetched.
+
+ * "git clone" learned to detach the HEAD in the resulting repository
+   when the user specifies a tag with "--branch" (e.g., "--branch=v1.0").
+   Clone also learned to print the usual "detached HEAD" advice in such
+   a case, similar to "git checkout v1.0".
+
+ * When showing a patch while ignoring whitespace changes, the context
+   lines are taken from the postimage, in order to make it easier to
+   view the output.
+
+ * "git diff --stat" learned to adjust the width of the output on
+   wider terminals, and give more columns to pathnames as needed.
+
+ * "diff-highlight" filter (in contrib/) was updated to produce more
+   aesthetically pleasing output.
+
+ * "fsck" learned "--no-dangling" option to omit dangling object
+   information.
+
+ * "git log -G" and "git log -S" learned to pay attention to the "-i"
+   option.  With "-i", "log -G" ignores the case when finding patch
+   hunks that introduce or remove a string that matches the given
+   pattern.  Similarly with "-i", "log -S" ignores the case when
+   finding the commit the given block of text appears or disappears
+   from the file.
+
+ * "git merge" in an interactive session learned to spawn the editor
+   by default to let the user edit the auto-generated merge message,
+   to encourage people to explain their merges better. Legacy scripts
+   can export GIT_MERGE_AUTOEDIT=no to retain the historical behavior.
+   Both "git merge" and "git pull" can be given --no-edit from the
+   command line to accept the auto-generated merge message.
+
+ * The advice message given when the user didn't give enough clue on
+   what to merge to "git pull" and "git merge" has been updated to
+   be more concise and easier to understand.
+
+ * "git push" learned the "--prune" option, similar to "git fetch".
+
+ * The whole directory that houses a top-level superproject managed by
+   "git submodule" can be moved to another place.
+
+ * "git symbolic-ref" learned the "--short" option to abbreviate the
+   refname it shows unambiguously.
+
+ * "git tag --list" can be given "--points-at <object>" to limit its
+   output to those that point at the given object.
+
+ * "gitweb" allows intermediate entries in the directory hierarchy
+   that leads to a project to be clicked, which in turn shows the
+   list of projects inside that directory.
+
+ * "gitweb" learned to read various pieces of information for the
+   repositories lazily, instead of reading everything that could be
+   needed (including the ones that are not necessary for a specific
+   task).
+
+ * Project search in "gitweb" shows the substring that matched in the
+   project name and description highlighted.
+
+ * HTTP transport learned to authenticate with a proxy if needed.
+
+ * A new script "diffall" is added to contrib/; it drives an
+   external tool to perform a directory diff of two Git revisions
+   in one go, unlike "difftool" that compares one file at a time.
+
+Foreign Interface
+
+ * Improved handling of views, labels and branches in "git-p4" (in contrib).
+
+ * "git-p4" (in contrib) suffered from unnecessary merge conflicts when
+   p4 expanded the embedded $RCS$-like keywords; it can be now told to
+   unexpand them.
+
+ * Some "git-svn" updates.
+
+ * "vcs-svn"/"svn-fe" learned to read dumps with svn-deltas and
+   support incremental imports.
+
+ * "git difftool/mergetool" learned to drive DeltaWalker.
+
+Performance
+
+ * Unnecessary calls to parse_object() "git upload-pack" makes in
+   response to "git fetch", have been eliminated, to help performance
+   in repositories with excessive number of refs.
+
+Internal Implementation (please report possible regressions)
+
+ * Recursive call chains in "git index-pack" to deal with long delta
+   chains have been flattened, to reduce the stack footprint.
+
+ * Use of add_extra_ref() API is now gone, to make it possible to
+   cleanly restructure the overall refs API.
+
+ * The command line parser of "git pack-objects" now uses parse-options
+   API.
+
+ * The test suite supports the new "test_pause" helper function.
+
+ * Parallel to the test suite, there is a beginning of performance
+   benchmarking framework.
+
+ * t/Makefile is adjusted to prevent newer versions of GNU make from
+   running tests in seemingly random order.
+
+ * The code to check if a path points at a file beyond a symbolic link
+   has been restructured to be thread-safe.
+
+ * When pruning directories that has become empty during "git prune"
+   and "git prune-packed", call closedir() that iterates over a
+   directory before rmdir() it.
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.7.9
+------------------
+
+Unless otherwise noted, all the fixes since v1.7.9 in the maintenance
+releases are contained in this release (see release notes to them for
+details).
+
+ * Build with NO_PERL_MAKEMAKER was broken and Git::I18N did not work
+   with versions of Perl older than 5.8.3.
+   (merge 5eb660e ab/perl-i18n later to maint).
+
+ * "git tag -s" honored "gpg.program" configuration variable since
+   1.7.9, but "git tag -v" and "git verify-tag" didn't.
+   (merge a2c2506 az/verify-tag-use-gpg-config later to maint).
+
+ * "configure" script learned to take "--with-sane-tool-path" from the
+   command line to record SANE_TOOL_PATH (used to avoid broken platform
+   tools in /usr/bin) in config.mak.autogen.  This may be useful for
+   people on Solaris who have saner tools outside /usr/xpg[46]/bin.
+
+ * zsh port of bash completion script needed another workaround.

+
+ * "git remote rename $a $b" were not careful to match the remote name

+
+ * "gitweb" used to produce a non-working link while showing the contents
+   of a blob, when JavaScript actions are enabled.

+Git v1.7.8.1 Release Notes
+==========================
+
+Fixes since v1.7.8
+------------------
+
+ * In some codepaths (notably, checkout and merge), the ignore patterns
+   recorded in $GIT_DIR/info/exclude were not honored. They now are.
+
+ * "git apply --check" did not error out when given an empty input
+   without any patch.
+
+ * "git archive" mistakenly allowed remote clients to ask for commits
+   that are not at the tip of any ref.
+
+ * "git checkout" and "git merge" treated in-tree .gitignore and exclude
+   file in $GIT_DIR/info/ directory inconsistently when deciding which
+   untracked files are ignored and expendable.
+
+ * LF-to-CRLF streaming filter used when checking out a large-ish blob
+   fell into an infinite loop with a rare input.
+
+ * The function header pattern for files with "diff=cpp" attribute did
+   not consider "type *funcname(type param1,..." as the beginning of a
+   function.
+
+ * The error message from "git diff" and "git status" when they fail
+   to inspect changes in submodules did not report which submodule they
+   had trouble with.
+
+ * After fetching from a remote that has very long refname, the reporting
+   output could have corrupted by overrunning a static buffer.
+
+ * "git pack-objects" avoids creating cyclic dependencies among deltas
+   when seeing a broken packfile that records the same object in both
+   the deflated form and as a delta.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.8.2 Release Notes
+==========================
+
+Fixes since v1.7.8.1
+--------------------
+
+ * Porcelain commands like "git reset" did not distinguish deletions
+   and type-changes from ordinary modification, and reported them with
+   the same 'M' moniker. They now use 'D' (for deletion) and 'T' (for
+   type-change) to match "git status -s" and "git diff --name-status".
+
+ * The configuration file parser used for sizes (e.g. bigFileThreshold)
+   did not correctly interpret 'g' suffix.
+
+ * The replacement implemention for snprintf used on platforms with
+   native snprintf that is broken did not use va_copy correctly.
+
+ * LF-to-CRLF streaming filter replaced all LF with CRLF, which might
+   be techinically correct but not friendly to people who are trying
+   to recover from earlier mistakes of using CRLF in the repository
+   data in the first place. It now refrains from doing so for LF that
+   follows a CR.
+
+ * git native connection going over TCP (not over SSH) did not set
+   SO_KEEPALIVE option which failed to receive link layer errors.
+
+ * "git branch -m <current branch> HEAD" is an obvious no-op but was not
+   allowed.
+
+ * "git checkout -m" did not recreate the conflicted state in a "both
+   sides added, without any common ancestor version" conflict
+   situation.
+
+ * "git cherry-pick $commit" (not a range) created an unnecessary
+   sequencer state and interfered with valid workflow to use the
+   command during a session to cherry-pick multiple commits.
+
+ * You could make "git commit" segfault by giving the "--no-message"
+   option.
+
+ * "fast-import" did not correctly update an existing notes tree,
+   possibly corrupting the fan-out.
+
+ * "git fetch-pack" accepted unqualified refs that do not begin with
+   refs/ by mistake and compensated it by matching the refspec with
+   tail-match, which was doubly wrong. This broke fetching from a
+   repository with a funny named ref "refs/foo/refs/heads/master" and a
+   'master' branch with "git fetch-pack refs/heads/master", as the
+   command incorrectly considered the former a "match".
+
+ * "git log --follow" did not honor the rename threshold score given
+   with the -M option (e.g. "-M50%").
+
+ * "git mv" gave suboptimal error/warning messages when it overwrites
+   target files. It also did not pay attention to "-v" option.
+
+ * Authenticated "git push" over dumb HTTP were broken with a recent
+   change and failed without asking for password when username is
+   given.
+
+ * "git push" to an empty repository over HTTP were broken with a
+   recent change to the ref handling.
+
+ * "git push -v" forgot how to be verbose by mistake. It now properly
+   becomes verbose when asked to.
+
+ * When a "reword" action in "git rebase -i" failed to run "commit --amend",
+   we did not give the control back to the user to resolve the situation, and
+   instead kept the original commit log message.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.8.4 Release Notes
+==========================

+
+ * The code to look up attributes for paths reused entries from a wrong

+
+ * A wildcard that matches deeper hierarchy given to the "diff-index" command,

+   matching files even when there is no change.
+
+ * When producing a "thin pack" (primarily used in bundles and smart

+
+ * "git send-email" did not properly treat sendemail.multiedit as a
+   boolean (e.g. setting it to "false" did not turn it off).

+Git v1.7.9.1 Release Notes
+==========================
+
+Fixes since v1.7.9
+------------------
+
+ * The makefile allowed environment variable X seep into it result in
+   command names suffixed with unnecessary strings.
+
+ * The set of included header files in compat/inet-{ntop,pton}
+   wrappers was updated for Windows some time ago, but in a way that
+   broke Solaris build.
+
+ * rpmbuild noticed an unpackaged but installed *.mo file and failed.
+
+ * Subprocesses spawned from various git programs were often left running
+   to completion even when the top-level process was killed.
+
+ * "git add -e" learned not to show a diff for an otherwise unmodified
+   submodule that only has uncommitted local changes in the patch
+   prepared by for the user to edit.
+
+ * Typo in "git branch --edit-description my-tpoic" was not diagnosed.
+
+ * Using "git grep -l/-L" together with options -W or --break may not
+   make much sense as the output is to only count the number of hits
+   and there is no place for file breaks, but the latter options made
+   "-l/-L" to miscount the hits.
+
+ * "git log --first-parent $pathspec" did not stay on the first parent
+   chain and veered into side branch from which the whole change to the
+   specified paths came.
+
+ * "git merge --no-edit $tag" failed to honor the --no-edit option.
+
+ * "git merge --ff-only $tag" failed because it cannot record the
+   required mergetag without creating a merge, but this is so common
+   operation for branch that is used _only_ to follow the upstream, so
+   it was changed to allow fast-forwarding without recording the mergetag.
+
+ * "git mergetool" now gives an empty file as the common base version
+   to the backend when dealing with the "both sides added, differently"
+   case.
+
+ * "git push -q" was not sufficiently quiet.
+
+ * When "git push" fails to update any refs, the client side did not
+   report an error correctly to the end user.
+
+ * "rebase" and "commit --amend" failed to work on commits with ancient
+   timestamps near year 1970.
+
+ * When asking for a tag to be pulled, "request-pull" did not show the
+   name of the tag prefixed with "tags/", which would have helped older
+   clients.
+
+ * "git submodule add $path" forgot to recompute the name to be stored
+   in .gitmodules when the submodule at $path was once added to the
+   superproject and already initialized.
+
+ * Many small corner case bugs on "git tag -n" was corrected.
+
+Also contains minor fixes and documentation updates.

+
+Fixes since v1.7.9.1
+--------------------
+
+ * Bash completion script (in contrib/) did not like a pattern that
+   begins with a dash to be passed to __git_ps1 helper function.
+
+ * Adaptation of the bash completion script (in contrib/) for zsh
+   incorrectly listed all subcommands when "git <TAB><TAB>" was given
+   to ask for list of porcelain subcommands.
+
+ * The build procedure for profile-directed optimized binary was not
+   working very well.
+
+ * Some systems need to explicitly link -lcharset to get locale_charset().
+
+ * t5541 ignored user-supplied port number used for HTTP server testing.
+
+ * The error message emitted when we see an empty loose object was
+   not phrased correctly.
+
+ * The code to ask for password did not fall back to the terminal
+   input when GIT_ASKPASS is set but does not work (e.g. lack of X
+   with GUI askpass helper).
+
+ * We failed to give the true terminal width to any subcommand when
+   they are invoked with the pager, i.e. "git -p cmd".
+
+ * map_user() was not rewriting its output correctly, which resulted
+   in the user visible symptom that "git blame -e" sometimes showed
+   excess '>' at the end of email addresses.
+
+ * "git checkout -b" did not allow switching out of an unborn branch.
+
+ * When you have both .../foo and .../foo.git, "git clone .../foo" did not
+   favor the former but the latter.
+
+ * "git commit" refused to create a commit when entries added with
+   "add -N" remained in the index, without telling Git what their content
+   in the next commit should be. We should have created the commit without
+   these paths.
+
+ * "git diff --stat" said "files", "insertions", and "deletions" even
+   when it is showing one "file", one "insertion" or one "deletion".
+
+ * The output from "git diff --stat" for two paths that have the same
+   amount of changes showed graph bars of different length due to the
+   way we handled rounding errors.
+
+ * "git grep" did not pay attention to -diff (hence -binary) attribute.
+
+ * The transport programs (fetch, push, clone)ignored --no-progress
+   and showed progress when sending their output to a terminal.
+
+ * Sometimes error status detected by a check in an earlier phase of
+   "git receive-pack" (the other end of "git push") was lost by later
+   checks, resulting in false indication of success.
+
+ * "git rev-list --verify" sometimes skipped verification depending on
+   the phase of the moon, which dates back to 1.7.8.x series.
+
+ * Search box in "gitweb" did not accept non-ASCII characters correctly.
+
+ * Search interface of "gitweb" did not show multiple matches in the same file
+   correctly.
+
+Also contains minor fixes and documentation updates.

+   the system.
+
+ * When the filter driver exits before reading the content before the
+   main git process writes the contents to be filtered to the pipe to
+   it, the latter could be killed with SIGPIPE instead of ignoring
+   such an event as an error.
+
+ * "git add --refresh <pathspec>" used to warn about unmerged paths
+   outside the given pathspec.
+
+ * The bulk check-in codepath in "git add" streamed contents that
+   needs smudge/clean filters without running them, instead of punting
+   and delegating to the codepath to run filters after slurping
+   everything to core.
+
+ * "git branch --with $that" assumed incorrectly that the user will never
+   ask the question with nonsense value in $that.
+
+ * "git bundle create" produced a corrupt bundle file upon seeing
+   commits with excessively long subject line.
+
+ * When a remote helper exits before reading the blank line from the
+   main git process to signal the end of commands, the latter could be
+   killed with SIGPIPE. Instead we should ignore such event as a
+   non-error.
+
+ * The commit log template given with "git merge --edit" did not have
+   a short instructive text like what "git commit" gives.
+
+ * "git rev-list --verify-objects -q" omitted the extra verification
+   it needs to do over "git rev-list --objects -q" by mistake.
+
+ * "gitweb" used to drop warnings in the log file when "heads" view is
+   accessed in a repository whose HEAD does not point at a valid
+   branch.
+
+ * An invalid regular expression pattern given by an end user made
+   "gitweb" to return garbled response.

+Git v1.7.9 Release Notes
+========================
+
+Updates since v1.7.8
+--------------------
+
+ * gitk updates accumulated since early 2011.
+
+ * git-gui updated to 0.16.0.
+
+ * git-p4 (in contrib/) updates.
+
+ * Git uses gettext to translate its most common interface messages
+   into the user's language if translations are available and the
+   locale is appropriately set. Distributors can drop new PO files
+   in po/ to add new translations.
+
+ * The code to handle username/password for HTTP transactions used in
+   "git push" & "git fetch" learned to talk "credential API" to
+   external programs to cache or store them, to allow integration with
+   platform native keychain mechanisms.
+
+ * The input prompts in the terminal use our own getpass() replacement
+   when possible. HTTP transactions used to ask for the username without
+   echoing back what was typed, but with this change you will see it as
+   you type.
+
+ * The internals of "revert/cherry-pick" have been tweaked to prepare
+   building more generic "sequencer" on top of the implementation that
+   drives them.
+
+ * "git rev-parse FETCH_HEAD" after "git fetch" without specifying
+   what to fetch from the command line will now show the commit that
+   would be merged if the command were "git pull".
+
+ * "git add" learned to stream large files directly into a packfile
+   instead of writing them into individual loose object files.
+
+ * "git checkout -B <current branch> <elsewhere>" is a more intuitive
+   way to spell "git reset --keep <elsewhere>".
+
+ * "git checkout" and "git merge" learned "--no-overwrite-ignore" option
+   to tell Git that untracked and ignored files are not expendable.
+
+ * "git commit --amend" learned "--no-edit" option to say that the
+   user is amending the tree being recorded, without updating the
+   commit log message.
+
+ * "git commit" and "git reset" re-learned the optimization to prime
+   the cache-tree information in the index, which makes it faster to
+   write a tree object out after the index entries are updated.
+
+ * "git commit" detects and rejects an attempt to stuff NUL byte in
+   the commit log message.
+
+ * "git commit" learned "-S" to GPG-sign the commit; this can be shown
+   with the "--show-signature" option to "git log".
+
+ * fsck and prune are relatively lengthy operations that still go
+   silent while making the end-user wait. They learned to give progress
+   output like other slow operations.
+
+ * The set of built-in function-header patterns for various languages
+   knows MATLAB.
+
+ * "git log --format='<format>'" learned new %g[nNeE] specifiers to
+   show information from the reflog entries when walking the reflog
+   (i.e. with "-g").
+
+ * "git pull" can be used to fetch and merge an annotated/signed tag,
+   instead of the tip of a topic branch. The GPG signature from the
+   signed tag is recorded in the resulting merge commit for later
+   auditing.
+
+ * "git log" learned "--show-signature" option to show the signed tag
+   that was merged that is embedded in the merge commit. It also can
+   show the signature made on the commit with "git commit -S".
+
+ * "git branch --edit-description" can be used to add descriptive text
+   to explain what a topic branch is about.
+
+ * "git fmt-merge-msg" learned to take the branch description into
+   account when preparing a merge summary that "git merge" records
+   when merging a local branch.
+
+ * "git request-pull" has been updated to convey more information
+   useful for integrators to decide if a topic is worth merging and
+   what is pulled is indeed what the requestor asked to pull,
+   including:
+
+   - the tip of the branch being requested to be merged;
+   - the branch description describing what the topic is about;
+   - the contents of the annotated tag, when requesting to pull a tag.
+
+ * "git pull" learned to notice 'pull.rebase' configuration variable,
+   which serves as a global fallback for setting 'branch.<name>.rebase'
+   configuration variable per branch.
+
+ * "git tag" learned "--cleanup" option to control how the whitespaces
+   and empty lines in tag message are cleaned up.
+
+ * "gitweb" learned to show side-by-side diff.
+
+Also contains minor documentation updates and code clean-ups.

+You can include one config file from another by setting the special
+`include.path` variable to the name of the file to be included. The
+included file is expanded immediately, as if its contents had been
+found at the location of the include directive. If the value of the
+`include.path` variable is a relative path, the path is considered to be
+relative to the configuration file in which the include directive was
+found. The value of `include.path` is subject to tilde expansion: `{tilde}/`
+is expanded to the value of `$HOME`, and `{tilde}user/` to the specified
+user's home directory. See below for examples.

+=======================
+
+NAME
+----
+git-credential-cache - helper to temporarily store passwords in memory
+
+SYNOPSIS
+--------
+-----------------------------
+git config credential.helper 'cache [options]'
+-----------------------------
+
+DESCRIPTION
+-----------
+
+This command caches credentials in memory for use by future git
+programs. The stored credentials never touch the disk, and are forgotten
+after a configurable timeout.  The cache is accessible over a Unix
+domain socket, restricted to the current user by filesystem permissions.
+
+You probably don't want to invoke this command directly; it is meant to
+be used as a credential helper by other parts of git. See
+linkgit:gitcredentials[7] or `EXAMPLES` below.
+
+OPTIONS
+-------
+
+--timeout <seconds>::
+
+	Number of seconds to cache credentials (default: 900).
+
+--socket <path>::
+
+	Use `<path>` to contact a running cache daemon (or start a new
+	cache daemon if one is not started). Defaults to
+	`~/.git-credential-cache/socket`. If your home directory is on a
+	network-mounted filesystem, you may need to change this to a
+	local filesystem.
+
+CONTROLLING THE DAEMON
+----------------------
+
+If you would like the daemon to exit early, forgetting all cached
+credentials before their timeout, you can issue an `exit` action:
+
+--------------------------------------
+git credential-cache exit
+--------------------------------------
+
+EXAMPLES
+--------
+
+The point of this helper is to reduce the number of times you must type
+your username or password. For example:
+
+------------------------------------
+$ git config credential.helper cache
+$ git push http://example.com/repo.git
+Username: <type your username>
+Password: <type your password>
+
+[work for 5 more minutes]
+$ git push http://example.com/repo.git
+[your credentials are used automatically]
+------------------------------------
+
+You can provide options via the credential.helper configuration
+variable (this example drops the cache time to 5 minutes):

+NAME
+----
+git-credential-store - helper to store credentials on disk
+
+SYNOPSIS
+--------
+-------------------
+git config credential.helper 'store [options]'
+-------------------
+
+DESCRIPTION
+-----------
+
+NOTE: Using this helper will store your passwords unencrypted on disk,
+protected only by filesystem permissions. If this is not an acceptable
+security tradeoff, try linkgit:git-credential-cache[1], or find a helper
+that integrates with secure storage provided by your operating system.
+
+This command stores credentials indefinitely on disk for use by future
+git programs.
+
+You probably don't want to invoke this command directly; it is meant to
+be used as a credential helper by other parts of git. See
+linkgit:gitcredentials[7] or `EXAMPLES` below.
+
+OPTIONS
+-------
+
+--store=<path>::
+
+	Use `<path>` to store credentials. The file will have its
+	filesystem permissions set to prevent other users on the system
+	from reading it, but will not be encrypted or otherwise
+	protected. Defaults to `~/.git-credentials`.
+
+EXAMPLES
+--------
+
+The point of this helper is to reduce the number of times you must type
+your username or password. For example:
+
+------------------------------------------
+$ git config credential.helper store
+$ git push http://example.com/repo.git
+Username: <type your username>
+Password: <type your password>
+
+[several days later]
+$ git push http://example.com/repo.git
+[your credentials are used automatically]
+------------------------------------------
+
+STORAGE FORMAT
+--------------
+
+The `.git-credentials` file is stored in plaintext. Each credential is
+stored on its own line as a URL like:
+
+------------------------------
+https://user:pass@example.com
+------------------------------
+
+When git needs authentication for a particular URL context,
+credential-store will consider that context a pattern to match against
+each entry in the credentials file.  If the protocol, hostname, and
+username (if we already have one) match, then the password is returned
+to git. See the discussion of configuration in linkgit:gitcredentials[7]
+for more information.

+git-fsck tests SHA1 and general object sanity, and it does full tracking
+of the resulting reachability and everything else. It prints out any
 corruption it finds (missing or bad objects), and if you use the
-'--unreachable' flag it will also print out objects that exist but
-that aren't reachable from any of the specified head nodes.
-
-So for example
-
-	git fsck --unreachable HEAD \
-		$(git for-each-ref --format="%(objectname)" refs/heads)
-
-will do quite a _lot_ of verification on the tree. There are a few
-extra validity tests to be added (make sure that tree objects are
-sorted properly etc), but on the whole if 'git fsck' is happy, you
-do have a valid tree.
+'--unreachable' flag it will also print out objects that exist but that
+aren't reachable from any of the specified head nodes (or the default
+set, as mentioned above).
 
 Any corrupt objects you will have to find in backups or other archives
 (i.e., you can just remove them and do an 'rsync' with some other site in
 the hopes that somebody else has the object you have corrupted).
 
-Of course, "valid tree" doesn't mean that it wasn't generated by some
-evil person, and the end result might be crap. git is a revision
-tracking system, not a quality assurance system ;)

+NAME

+git-p4 - Import from and submit to Perforce repositories
+
+
+SYNOPSIS
+--------
+[verse]
+'git p4 clone' [<sync options>] [<clone options>] <p4 depot path>...
+'git p4 sync' [<sync options>] [<p4 depot path>...]
+'git p4 rebase'
+'git p4 submit' [<submit options>] [<master branch name>]
+
+
+DESCRIPTION
+-----------
+This command provides a way to interact with p4 repositories
+using git.
+
+Create a new git repository from an existing p4 repository using
+'git p4 clone', giving it one or more p4 depot paths.  Incorporate
+new commits from p4 changes with 'git p4 sync'.  The 'sync' command
+is also used to include new branches from other p4 depot paths.
+Submit git changes back to p4 using 'git p4 submit'.  The command
+'git p4 rebase' does a sync plus rebases the current branch onto
+the updated p4 remote branch.
+
+
+EXAMPLE
+-------
+* Create an alias for 'git p4', using the full path to the 'git-p4'
+  script if needed:
++
+------------
+$ git config --global alias.p4 '!git-p4'
+------------
+
+* Clone a repository:
++
+------------
+$ git p4 clone //depot/path/project
+------------
+
+* Do some work in the newly created git repository:
++
+------------
+$ cd project
+$ vi foo.h
+$ git commit -a -m "edited foo.h"
+------------
+
+* Update the git repository with recent changes from p4, rebasing your
+  work on top:
++
+------------
+$ git p4 rebase
+------------
+
+* Submit your commits back to p4:
++
+------------
+$ git p4 submit
+------------
+
+
+COMMANDS
+--------
+
+Clone
+~~~~~
+Generally, 'git p4 clone' is used to create a new git directory
+from an existing p4 repository:
+------------
+$ git p4 clone //depot/path/project
+------------
+This:
+
+1.   Creates an empty git repository in a subdirectory called 'project'.
++
+2.   Imports the full contents of the head revision from the given p4
+depot path into a single commit in the git branch 'refs/remotes/p4/master'.
++
+3.   Creates a local branch, 'master' from this remote and checks it out.
+
+To reproduce the entire p4 history in git, use the '@all' modifier on
+the depot path:
+------------
+$ git p4 clone //depot/path/project@all
+------------
+
+
+Sync
+~~~~
+As development continues in the p4 repository, those changes can
+be included in the git repository using:
+------------
+$ git p4 sync
+------------
+This command finds new changes in p4 and imports them as git commits.
+
+P4 repositories can be added to an existing git repository using
+'git p4 sync' too:
+------------
+$ mkdir repo-git
+$ cd repo-git
+$ git init
+$ git p4 sync //path/in/your/perforce/depot
+------------
+This imports the specified depot into
+'refs/remotes/p4/master' in an existing git repository.  The
+'--branch' option can be used to specify a different branch to
+be used for the p4 content.
+
+If a git repository includes branches 'refs/remotes/origin/p4', these
+will be fetched and consulted first during a 'git p4 sync'.  Since
+importing directly from p4 is considerably slower than pulling changes
+from a git remote, this can be useful in a multi-developer environment.
+
+
+Rebase
+~~~~~~
+A common working pattern is to fetch the latest changes from the p4 depot
+and merge them with local uncommitted changes.  Often, the p4 repository
+is the ultimate location for all code, thus a rebase workflow makes
+sense.  This command does 'git p4 sync' followed by 'git rebase' to move
+local commits on top of updated p4 changes.
+------------
+$ git p4 rebase
+------------
+
+
+Submit
+~~~~~~
+Submitting changes from a git repository back to the p4 repository
+requires a separate p4 client workspace.  This should be specified
+using the 'P4CLIENT' environment variable or the git configuration
+variable 'git-p4.client'.  The p4 client must exist, but the client root
+will be created and populated if it does not already exist.
+
+To submit all changes that are in the current git branch but not in
+the 'p4/master' branch, use:
+------------
+$ git p4 submit
+------------
+
+To specify a branch other than the current one, use:
+------------
+$ git p4 submit topicbranch
+------------
+
+The upstream reference is generally 'refs/remotes/p4/master', but can
+be overridden using the '--origin=' command-line option.
+
+The p4 changes will be created as the user invoking 'git p4 submit'. The
+'--preserve-user' option will cause ownership to be modified
+according to the author of the git commit.  This option requires admin
+privileges in p4, which can be granted using 'p4 protect'.
+
+
+OPTIONS
+-------
+
+General options
+~~~~~~~~~~~~~~~
+All commands except clone accept this option.
+
+--git-dir <dir>::
+	Set the 'GIT_DIR' environment variable.  See linkgit:git[1].
+
+Sync options
+~~~~~~~~~~~~
+These options can be used in the initial 'clone' as well as in
+subsequent 'sync' operations.
+
+--branch <branch>::
+	Import changes into given branch.  If the branch starts with
+	'refs/', it will be used as is, otherwise the path 'refs/heads/'
+	will be prepended.  The default branch is 'master'.  If used
+	with an initial clone, no HEAD will be checked out.
++
+This example imports a new remote "p4/proj2" into an existing
+git repository:
++
+----
+    $ git init
+    $ git p4 sync --branch=refs/remotes/p4/proj2 //depot/proj2
+----
+
+--detect-branches::
+	Use the branch detection algorithm to find new paths in p4.  It is
+	documented below in "BRANCH DETECTION".
+
+--changesfile <file>::
+	Import exactly the p4 change numbers listed in 'file', one per
+	line.  Normally, 'git p4' inspects the current p4 repository
+	state and detects the changes it should import.
+
+--silent::
+	Do not print any progress information.
+
+--verbose::
+	Provide more progress information.
+
+--detect-labels::
+	Query p4 for labels associated with the depot paths, and add
+	them as tags in git.
+
+--import-local::
+	By default, p4 branches are stored in 'refs/remotes/p4/',
+	where they will be treated as remote-tracking branches by
+	linkgit:git-branch[1] and other commands.  This option instead
+	puts p4 branches in 'refs/heads/p4/'.  Note that future
+	sync operations must specify '--import-local' as well so that
+	they can find the p4 branches in refs/heads.
+
+--max-changes <n>::
+	Limit the number of imported changes to 'n'.  Useful to
+	limit the amount of history when using the '@all' p4 revision
+	specifier.
+
+--keep-path::
+	The mapping of file names from the p4 depot path to git, by
+	default, involves removing the entire depot path.  With this
+	option, the full p4 depot path is retained in git.  For example,
+	path '//depot/main/foo/bar.c', when imported from
+	'//depot/main/', becomes 'foo/bar.c'.  With '--keep-path', the
+	git path is instead 'depot/main/foo/bar.c'.
+
+--use-client-spec::
+	Use a client spec to find the list of interesting files in p4.
+	See the "CLIENT SPEC" section below.
+
+Clone options
+~~~~~~~~~~~~~
+These options can be used in an initial 'clone', along with the 'sync'
+options described above.
+
+--destination <directory>::
+	Where to create the git repository.  If not provided, the last
+	component in the p4 depot path is used to create a new
+	directory.
+
+--bare::
+	Perform a bare clone.  See linkgit:git-clone[1].
+
+-/ <path>::
+	Exclude selected depot paths when cloning.
+
+Submit options
+~~~~~~~~~~~~~~
+These options can be used to modify 'git p4 submit' behavior.
+
+--verbose::
+	Provide more progress information.
+
+--origin <commit>::
+	Upstream location from which commits are identified to submit to
+	p4.  By default, this is the most recent p4 commit reachable
+	from 'HEAD'.
+
+-M[<n>]::
+	Detect renames.  See linkgit:git-diff[1].  Renames will be
+	represented in p4 using explicit 'move' operations.  There
+	is no corresponding option to detect copies, but there are
+	variables for both moves and copies.
+
+--preserve-user::
+	Re-author p4 changes before submitting to p4.  This option
+	requires p4 admin privileges.
+
+
+DEPOT PATH SYNTAX
+-----------------
+The p4 depot path argument to 'git p4 sync' and 'git p4 clone' can
+be one or more space-separated p4 depot paths, with an optional
+p4 revision specifier on the end:
+
+"//depot/my/project"::
+    Import one commit with all files in the '#head' change under that tree.
+
+"//depot/my/project@all"::
+    Import one commit for each change in the history of that depot path.
+
+"//depot/my/project@1,6"::
+    Import only changes 1 through 6.
+
+"//depot/proj1@all //depot/proj2@all"::
+    Import all changes from both named depot paths into a single
+    repository.  Only files below these directories are included.
+    There is not a subdirectory in git for each "proj1" and "proj2".
+    You must use the '--destination' option when specifying more
+    than one depot path.  The revision specifier must be specified
+    identically on each depot path.  If there are files in the
+    depot paths with the same name, the path with the most recently
+    updated version of the file is the one that appears in git.
+
+See 'p4 help revisions' for the full syntax of p4 revision specifiers.
+
+
+CLIENT SPEC
+-----------
+The p4 client specification is maintained with the 'p4 client' command
+and contains among other fields, a View that specifies how the depot
+is mapped into the client repository.  The 'clone' and 'sync' commands
+can consult the client spec when given the '--use-client-spec' option or
+when the useClientSpec variable is true.  After 'git p4 clone', the
+useClientSpec variable is automatically set in the repository
+configuration file.  This allows future 'git p4 submit' commands to
+work properly; the submit command looks only at the variable and does
+not have a command-line option.
+
+The full syntax for a p4 view is documented in 'p4 help views'.  Git-p4
+knows only a subset of the view syntax.  It understands multi-line
+mappings, overlays with '+', exclusions with '-' and double-quotes
+around whitespace.  Of the possible wildcards, git-p4 only handles
+'...', and only when it is at the end of the path.  Git-p4 will complain
+if it encounters an unhandled wildcard.
+
+Bugs in the implementation of overlap mappings exist.  If multiple depot
+paths map through overlays to the same location in the repository,
+git-p4 can choose the wrong one.  This is hard to solve without
+dedicating a client spec just for git-p4.
+
+The name of the client can be given to git-p4 in multiple ways.  The
+variable 'git-p4.client' takes precedence if it exists.  Otherwise,
+normal p4 mechanisms of determining the client are used:  environment
+variable P4CLIENT, a file referenced by P4CONFIG, or the local host name.
+
+
+BRANCH DETECTION
+----------------
+P4 does not have the same concept of a branch as git.  Instead,
+p4 organizes its content as a directory tree, where by convention
+different logical branches are in different locations in the tree.
+The 'p4 branch' command is used to maintain mappings between
+different areas in the tree, and indicate related content.  'git p4'
+can use these mappings to determine branch relationships.
+
+If you have a repository where all the branches of interest exist as
+subdirectories of a single depot path, you can use '--detect-branches'
+when cloning or syncing to have 'git p4' automatically find
+subdirectories in p4, and to generate these as branches in git.
+
+For example, if the P4 repository structure is:
+----
+//depot/main/...
+//depot/branch1/...
+----
+
+And "p4 branch -o branch1" shows a View line that looks like:
+----
+//depot/main/... //depot/branch1/...
+----
+
+Then this 'git p4 clone' command:
+----
+git p4 clone --detect-branches //depot@all
+----
+produces a separate branch in 'refs/remotes/p4/' for //depot/main,
+called 'master', and one for //depot/branch1 called 'depot/branch1'.
+
+However, it is not necessary to create branches in p4 to be able to use
+them like branches.  Because it is difficult to infer branch
+relationships automatically, a git configuration setting
+'git-p4.branchList' can be used to explicitly identify branch
+relationships.  It is a list of "source:destination" pairs, like a
+simple p4 branch specification, where the "source" and "destination" are
+the path elements in the p4 repository.  The example above relied on the
+presence of the p4 branch.  Without p4 branches, the same result will
+occur with:
+----
+git config git-p4.branchList main:branch1
+git p4 clone --detect-branches //depot@all
+----
+
+
+PERFORMANCE
+-----------
+The fast-import mechanism used by 'git p4' creates one pack file for
+each invocation of 'git p4 sync'.  Normally, git garbage compression
+(linkgit:git-gc[1]) automatically compresses these to fewer pack files,
+but explicit invocation of 'git repack -adf' may improve performance.
+

+	'-h <host>'.
+	The environment variable 'P4HOST' can be used instead.
+
+git-p4.client::
+	Client specified as an option to all p4 commands, with
+	'-c <client>', including the client spec.
+
+Clone and sync variables
+~~~~~~~~~~~~~~~~~~~~~~~~
+git-p4.syncFromOrigin::
+	Because importing commits from other git repositories is much faster
+	than importing them from p4, a mechanism exists to find p4 changes
+	first in git remotes.  If branches exist under 'refs/remote/origin/p4',
+	those will be fetched and used when syncing from p4.  This
+	variable can be set to 'false' to disable this behavior.
+
+git-p4.branchUser::
+	One phase in branch detection involves looking at p4 branches
+	to find new ones to import.  By default, all branches are
+	inspected.  This option limits the search to just those owned
+	by the single user named in the variable.
+
+git-p4.branchList::
+	List of branches to be imported when branch detection is
+	enabled.  Each entry should be a pair of branch names separated
+	by a colon (:).  This example declares that both branchA and
+	branchB were created from main:
++
+-------------
+git config       git-p4.branchList main:branchA
+git config --add git-p4.branchList main:branchB
+-------------
+
+git-p4.useClientSpec::
+	Specify that the p4 client spec should be used to identify p4
+	depot paths of interest.  This is equivalent to specifying the
+	option '--use-client-spec'.  See the "CLIENT SPEC" section above.
+	This variable is a boolean, not the name of a p4 client.
+
+Submit variables
+~~~~~~~~~~~~~~~~
+git-p4.detectRenames::
+	Detect renames.  See linkgit:git-diff[1].
+
+git-p4.detectCopies::
+	Detect copies.  See linkgit:git-diff[1].
+
+git-p4.detectCopiesHarder::
+	Detect copies harder.  See linkgit:git-diff[1].
+
+git-p4.preserveUser::
+	On submit, re-author changes to reflect the git author,
+	regardless of who invokes 'git p4 submit'.
+
+git-p4.allowMissingP4Users::
+	When 'preserveUser' is true, 'git p4' normally dies if it
+	cannot find an author in the p4 user map.  This setting
+	submits the change regardless.
+
+git-p4.skipSubmitEdit::
+	The submit process invokes the editor before each p4 change
+	is submitted.  If this setting is true, though, the editing
+	step is skipped.
+
+git-p4.skipSubmitEditCheck::
+	After editing the p4 change message, 'git p4' makes sure that
+	the description really was changed by looking at the file
+	modification time.  This option disables that test.
+
+git-p4.allowSubmit::
+	By default, any branch can be used as the source for a 'git p4
+	submit' operation.  This configuration variable, if set, permits only
+	the named branches to be used as submit sources.  Branch names
+	must be the short names (no "refs/heads/"), and should be
+	separated by commas (","), with no spaces.
+
+git-p4.skipUserNameCheck::
+	If the user running 'git p4 submit' does not exist in the p4
+	user map, 'git p4' exits.  This option can be used to force
+	submission regardless.
+
+git-p4.attemptRCSCleanup::
+    If enabled, 'git p4 submit' will attempt to cleanup RCS keywords
+    ($Header$, etc). These would otherwise cause merge conflicts and prevent
+    the submit going ahead. This option should be considered experimental at
+    present.
+
+IMPLEMENTATION DETAILS
+----------------------
+* Changesets from p4 are imported using git fast-import.
+* Cloning or syncing does not require a p4 client; file contents are
+  collected using 'p4 print'.
+* Submitting requires a p4 client, which is not in the same location
+  as the git repository.  Patches are applied, one at a time, to
+  this p4 client and submitted from there.
+* Each commit imported by 'git p4' has a line at the end of the log
+  message indicating the p4 depot location and change number.  This
+  line is used by later 'git p4 sync' operations to know which p4
+  changes are new.

 DESCRIPTION
 -----------
-Remove multiple empty lines, and empty lines at beginning and end.
+
+Clean the input in the manner used by 'git' for text such as commit
+messages, notes, tags and branch descriptions.
+
+With no arguments, this will:
+
+- remove trailing whitespace from all lines
+- collapse multiple consecutive empty lines into one empty line
+- remove empty lines from the beginning and end of the input
+- add a missing '\n' to the last line if necessary.
+
+In the case where the input consists entirely of whitespace characters, no
+output will be produced.
+
+*NOTE*: This is intended for cleaning metadata, prefer the `--whitespace=fix`
+mode of linkgit:git-apply[1] for correcting whitespace of patches or files in
+the repository.

+gitcredentials(7)
+=================
+
+NAME
+----
+gitcredentials - providing usernames and passwords to git
+
+SYNOPSIS
+--------
+------------------
+git config credential.https://example.com.username myusername
+git config credential.helper "$helper $options"
+------------------
+
+DESCRIPTION
+-----------
+
+Git will sometimes need credentials from the user in order to perform
+operations; for example, it may need to ask for a username and password
+in order to access a remote repository over HTTP. This manual describes
+the mechanisms git uses to request these credentials, as well as some
+features to avoid inputting these credentials repeatedly.
+
+REQUESTING CREDENTIALS
+----------------------
+
+Without any credential helpers defined, git will try the following
+strategies to ask the user for usernames and passwords:
+
+1. If the `GIT_ASKPASS` environment variable is set, the program
+   specified by the variable is invoked. A suitable prompt is provided
+   to the program on the command line, and the user's input is read
+   from its standard output.
+
+2. Otherwise, if the `core.askpass` configuration variable is set, its
+   value is used as above.
+
+3. Otherwise, if the `SSH_ASKPASS` environment variable is set, its
+   value is used as above.
+
+4. Otherwise, the user is prompted on the terminal.
+
+AVOIDING REPETITION
+-------------------
+
+It can be cumbersome to input the same credentials over and over.  Git
+provides two methods to reduce this annoyance:
+
+1. Static configuration of usernames for a given authentication context.
+
+2. Credential helpers to cache or store passwords, or to interact with
+   a system password wallet or keychain.
+
+The first is simple and appropriate if you do not have secure storage available
+for a password. It is generally configured by adding this to your config:
+
+---------------------------------------
+[credential "https://example.com"]
+	username = me
+---------------------------------------
+
+Credential helpers, on the other hand, are external programs from which git can
+request both usernames and passwords; they typically interface with secure
+storage provided by the OS or other programs.
+
+To use a helper, you must first select one to use. Git currently
+includes the following helpers:
+
+cache::
+
+	Cache credentials in memory for a short period of time. See
+	linkgit:git-credential-cache[1] for details.
+
+store::
+
+	Store credentials indefinitely on disk. See
+	linkgit:git-credential-store[1] for details.
+
+You may also have third-party helpers installed; search for
+`credential-*` in the output of `git help -a`, and consult the
+documentation of individual helpers.  Once you have selected a helper,
+you can tell git to use it by putting its name into the
+credential.helper variable.
+
+1. Find a helper.
++
+-------------------------------------------
+$ git help -a | grep credential-
+credential-foo
+-------------------------------------------
+
+2. Read its description.
++
+-------------------------------------------
+$ git help credential-foo
+-------------------------------------------
+
+3. Tell git to use it.
++
+-------------------------------------------
+$ git config --global credential.helper foo
+-------------------------------------------
+
+If there are multiple instances of the `credential.helper` configuration
+variable, each helper will be tried in turn, and may provide a username,
+password, or nothing. Once git has acquired both a username and a
+password, no more helpers will be tried.
+
+
+CREDENTIAL CONTEXTS
+-------------------
+
+Git considers each credential to have a context defined by a URL. This context
+is used to look up context-specific configuration, and is passed to any
+helpers, which may use it as an index into secure storage.
+
+For instance, imagine we are accessing `https://example.com/foo.git`. When git
+looks into a config file to see if a section matches this context, it will
+consider the two a match if the context is a more-specific subset of the
+pattern in the config file. For example, if you have this in your config file:
+
+--------------------------------------
+[credential "https://example.com"]
+	username = foo
+--------------------------------------
+
+then we will match: both protocols are the same, both hosts are the same, and
+the "pattern" URL does not care about the path component at all. However, this
+context would not match:
+
+--------------------------------------
+[credential "https://kernel.org"]
+	username = foo
+--------------------------------------
+
+because the hostnames differ. Nor would it match `foo.example.com`; git
+compares hostnames exactly, without considering whether two hosts are part of
+the same domain. Likewise, a config entry for `http://example.com` would not
+match: git compares the protocols exactly.
+
+
+CONFIGURATION OPTIONS
+---------------------
+
+Options for a credential context can be configured either in
+`credential.\*` (which applies to all credentials), or
+`credential.<url>.\*`, where <url> matches the context as described
+above.
+
+The following options are available in either location:
+
+helper::
+
+	The name of an external credential helper, and any associated options.
+	If the helper name is not an absolute path, then the string `git
+	credential-` is prepended. The resulting string is executed by the
+	shell (so, for example, setting this to `foo --option=bar` will execute
+	`git credential-foo --option=bar` via the shell. See the manual of
+	specific helpers for examples of their use.
+
+username::
+
+	A default username, if one is not provided in the URL.
+
+useHttpPath::
+
+	By default, git does not consider the "path" component of an http URL
+	to be worth matching via external helpers. This means that a credential
+	stored for `https://example.com/foo.git` will also be used for
+	`https://example.com/bar.git`. If you do want to distinguish these
+	cases, set this option to `true`.
+
+
+CUSTOM HELPERS
+--------------
+
+You can write your own custom helpers to interface with any system in
+which you keep credentials. See the documentation for git's
+link:technical/api-credentials.html[credentials API] for details.

+Subject: Using signed tag in pull requests
+Abstract: Beginning v1.7.9, a contributor can push a signed tag to her
+ publishing repository and ask her integrator to pull it. This assures the
+ integrator that the pulled history is authentic and allows others to
+ later validate it.
+Content-type: text/asciidoc
+
+Using signed tag in pull requests
+=================================
+
+A typical distributed workflow using Git is for a contributor to fork a
+project, build on it, publish the result to her public repository, and ask
+the "upstream" person (often the owner of the project where she forked
+from) to pull from her public repository. Requesting such a "pull" is made
+easy by the `git request-pull` command.
+
+Earlier, a typical pull request may have started like this:
+
+------------
+ The following changes since commit 406da78032179...:
+
+   Froboz 3.2 (2011-09-30 14:20:57 -0700)
+
+ are available in the git repository at:
+
+   example.com:/git/froboz.git for-xyzzy
+------------
+
+followed by a shortlog of the changes and a diffstat.
+
+The request was for a branch name (e.g. `for-xyzzy`) in the public
+repository of the contributor, and even though it stated where the
+contributor forked her work from, the message did not say anything about
+the commit to expect at the tip of the for-xyzzy branch. If the site that
+hosts the public repository of the contributor cannot be fully trusted, it
+was unnecessarily hard to make sure what was pulled by the integrator was
+genuinely what the contributor had produced for the project. Also there
+was no easy way for third-party auditors to later verify the resulting
+history.
+
+Starting from Git release v1.7.9, a contributor can add a signed tag to
+the commit at the tip of the history and ask the integrator to pull that
+signed tag. When the integrator runs `git pull`, the signed tag is
+automatically verified to assure that the history is not tampered with.
+In addition, the resulting merge commit records the content of the signed
+tag, so that other people can verify that the branch merged by the
+integrator was signed by the contributor, without fetching the signed tag
+used to validate the pull request separately and keeping it in the refs
+namespace.
+
+This document describes the workflow between the contributor and the
+integrator, using Git v1.7.9 or later.
+
+
+A contributor or a lieutenant
+-----------------------------
+
+After preparing her work to be pulled, the contributor uses `git tag -s`
+to create a signed tag:
+
+------------
+ $ git checkout work
+ $ ... "git pull" from sublieutenants, "git commit" your own work ...
+ $ git tag -s -m "Completed frotz feature" frotz-for-xyzzy work
+------------
+
+Note that this example uses the `-m` option to create a signed tag with
+just a one-liner message, but this is for illustration purposes only. It
+is advisable to compose a well-written explanation of what the topic does
+to justify why it is worthwhile for the integrator to pull it, as this
+message will eventually become part of the final history after the
+integrator responds to the pull request (as we will see later).
+
+Then she pushes the tag out to her public repository:
+
+------------
+ $ git push example.com:/git/froboz.git/ +frotz-for-xyzzy
+------------
+
+There is no need to push the `work` branch or anything else.
+
+Note that the above command line used a plus sign at the beginning of
+`+frotz-for-xyzzy` to allow forcing the update of a tag, as the same
+contributor may want to reuse a signed tag with the same name after the
+previous pull request has already been responded to.
+
+The contributor then prepares a message to request a "pull":
+
+------------
+ $ git request-pull v3.2 example.com:/git/froboz.git/ frotz-for-xyzzy >msg.txt
+------------
+
+The arguments are:
+
+. the version of the integrator's commit the contributor based her work on;
+. the URL of the repository, to which the contributor has pushed what she
+  wants to get pulled; and
+. the name of the tag the contributor wants to get pulled (earlier, she could
+  write only a branch name here).
+
+The resulting msg.txt file begins like so:
+
+------------
+ The following changes since commit 406da78032179...:
+
+   Froboz 3.2 (2011-09-30 14:20:57 -0700)
+
+ are available in the git repository at:
+
+   example.com:/git/froboz.git tags/frotz-for-xyzzy
+
+ for you to fetch changes up to 703f05ad5835c...:
+
+   Add tests and documentation for frotz (2011-12-02 10:02:52 -0800)
+
+ -----------------------------------------------
+ Completed frotz feature
+ -----------------------------------------------
+------------
+
+followed by a shortlog of the changes and a diffstat.  Comparing this with
+the earlier illustration of the output from the traditional `git request-pull`
+command, the reader should notice that:
+
+. The tip commit to expect is shown to the integrator; and
+. The signed tag message is shown prominently between the dashed lines
+  before the shortlog.
+
+The latter is why the contributor would want to justify why pulling her
+work is worthwhile when creating the signed tag.  The contributor then
+opens her favorite MUA, reads msg.txt, edits and sends it to her upstream
+integrator.
+
+
+Integrator
+----------
+
+After receiving such a pull request message, the integrator fetches and
+integrates the tag named in the request, with:
+
+------------
+ $ git pull example.com:/git/froboz.git/ tags/frotz-for-xyzzy
+------------
+
+This operation will always open an editor to allow the integrator to fine
+tune the commit log message when merging a signed tag.  Also, pulling a
+signed tag will always create a merge commit even when the integrator does
+not have any new commit since the contributor's work forked (i.e. 'fast
+forward'), so that the integrator can properly explain what the merge is
+about and why it was made.
+
+In the editor, the integrator will see something like this:
+
+------------
+ Merge tag 'frotz-for-xyzzy' of example.com:/git/froboz.git/
+
+ Completed frotz feature
+ # gpg: Signature made Fri 02 Dec 2011 10:03:01 AM PST using RSA key ID 96AFE6CB
+ # gpg: Good signature from "Con Tributor <nitfol@example.com>"
+------------
+
+Notice that the message recorded in the signed tag "Completed frotz
+feature" appears here, and again that is why it is important for the
+contributor to explain her work well when creating the signed tag.
+
+As usual, the lines commented with `#` are stripped out. The resulting
+commit records the signed tag used for this validation in a hidden field
+so that it can later be used by others to audit the history. There is no
+need for the integrator to keep a separate copy of the tag in his
+repository (i.e. `git tag -l` won't list the `frotz-for-xyzzy` tag in the
+above example), and there is no need to publish the tag to his public
+repository, either.
+
+After the integrator responds to the pull request and her work becomes
+part of the permanent history, the contributor can remove the tag from
+her public repository, if she chooses, in order to keep the tag namespace
+of her public repository clean, with:
+
+------------
+ $ git push example.com:/git/froboz.git :frotz-for-xyzzy
+------------
+
+
+Auditors
+--------
+
+The `--show-signature` option can be given to `git log` or `git show` and
+shows the verification status of the embedded signed tag in merge commits
+created when the integrator responded to a pull request of a signed tag.
+
+A typical output from `git show --show-signature` may look like this:
+
+------------
+ $ git show --show-signature
+ commit 02306ef6a3498a39118aef9df7975bdb50091585
+ merged tag 'frotz-for-xyzzy'
+ gpg: Signature made Fri 06 Jan 2012 12:41:49 PM PST using RSA key ID 96AFE6CB
+ gpg: Good signature from "Con Tributor <nitfol@example.com>"
+ Merge: 406da78 703f05a

+
+     * tag 'frotz-for-xyzzy' (100 commits)
+       Add tests and documentation for frotz
+       ...
+------------
+
+There is no need for the auditor to explicitly fetch the contributor's
+signature, or to even be aware of what tag(s) the contributor and integrator
+used to communicate the signature.  All the required information is recorded
+as part of the merge commit.

+config API
+==========
+
+The config API gives callers a way to access git configuration files
+(and files which have the same syntax). See linkgit:git-config[1] for a
+discussion of the config file syntax.
+
+General Usage
+-------------
+
+Config files are parsed linearly, and each variable found is passed to a
+caller-provided callback function. The callback function is responsible
+for any actions to be taken on the config option, and is free to ignore
+some options. It is not uncommon for the configuration to be parsed
+several times during the run of a git program, with different callbacks
+picking out different variables useful to themselves.
+
+A config callback function takes three parameters:
+
+- the name of the parsed variable. This is in canonical "flat" form: the
+  section, subsection, and variable segments will be separated by dots,
+  and the section and variable segments will be all lowercase. E.g.,
+  `core.ignorecase`, `diff.SomeType.textconv`.
+
+- the value of the found variable, as a string. If the variable had no
+  value specified, the value will be NULL (typically this means it
+  should be interpreted as boolean true).
+
+- a void pointer passed in by the caller of the config API; this can
+  contain callback-specific data
+
+A config callback should return 0 for success, or -1 if the variable
+could not be parsed properly.
+
+Basic Config Querying
+---------------------
+
+Most programs will simply want to look up variables in all config files
+that git knows about, using the normal precedence rules. To do this,
+call `git_config` with a callback function and void data pointer.
+
+`git_config` will read all config sources in order of increasing
+priority. Thus a callback should typically overwrite previously-seen
+entries with new ones (e.g., if both the user-wide `~/.gitconfig` and
+repo-specific `.git/config` contain `color.ui`, the config machinery
+will first feed the user-wide one to the callback, and then the
+repo-specific one; by overwriting, the higher-priority repo-specific
+value is left at the end).
+
+The `git_config_with_options` function lets the caller examine config
+while adjusting some of the default behavior of `git_config`. It should
+almost never be used by "regular" git code that is looking up
+configuration variables. It is intended for advanced callers like
+`git-config`, which are intentionally tweaking the normal config-lookup
+process. It takes two extra parameters:
+
+`filename`::
+If this parameter is non-NULL, it specifies the name of a file to
+parse for configuration, rather than looking in the usual files. Regular
+`git_config` defaults to `NULL`.
+
+`respect_includes`::
+Specify whether include directives should be followed in parsed files.
+Regular `git_config` defaults to `1`.
+
+There is a special version of `git_config` called `git_config_early`.
+This version takes an additional parameter to specify the repository
+config, instead of having it looked up via `git_path`. This is useful
+early in a git program before the repository has been found. Unless
+you're working with early setup code, you probably don't want to use
+this.
+
+Reading Specific Files
+----------------------
+
+To read a specific file in git-config format, use
+`git_config_from_file`. This takes the same callback and data parameters
+as `git_config`.
+
+Value Parsing Helpers
+---------------------
+
+To aid in parsing string values, the config API provides callbacks with
+a number of helper functions, including:
+
+`git_config_int`::
+Parse the string to an integer, including unit factors. Dies on error;
+otherwise, returns the parsed result.
+
+`git_config_ulong`::
+Identical to `git_config_int`, but for unsigned longs.
+
+`git_config_bool`::
+Parse a string into a boolean value, respecting keywords like "true" and
+"false". Integer values are converted into true/false values (when they
+are non-zero or zero, respectively). Other values cause a die(). If
+parsing is successful, the return value is the result.
+
+`git_config_bool_or_int`::
+Same as `git_config_bool`, except that integers are returned as-is, and
+an `is_bool` flag is unset.
+
+`git_config_maybe_bool`::
+Same as `git_config_bool`, except that it returns -1 on error rather
+than dying.
+
+`git_config_string`::
+Allocates and copies the value string into the `dest` parameter; if no
+string is given, prints an error message and returns -1.
+
+`git_config_pathname`::
+Similar to `git_config_string`, but expands `~` or `~user` into the
+user's home directory when found at the beginning of the path.
+
+Include Directives
+------------------
+
+By default, the config parser does not respect include directives.
+However, a caller can use the special `git_config_include` wrapper
+callback to support them. To do so, you simply wrap your "real" callback
+function and data pointer in a `struct config_include_data`, and pass
+the wrapper to the regular config-reading functions. For example:
+
+-------------------------------------------
+int read_file_with_include(const char *file, config_fn_t fn, void *data)
+{
+	struct config_include_data inc = CONFIG_INCLUDE_INIT;
+	inc.fn = fn;
+	inc.data = data;
+	return git_config_from_file(git_config_include, file, &inc);
+}
+-------------------------------------------
+
+`git_config` respects includes automatically. The lower-level
+`git_config_from_file` does not.

+credentials API
+===============
+
+The credentials API provides an abstracted way of gathering username and
+password credentials from the user (even though credentials in the wider
+world can take many forms, in this document the word "credential" always
+refers to a username and password pair).
+
+Data Structures
+---------------
+
+`struct credential`::
+
+	This struct represents a single username/password combination
+	along with any associated context. All string fields should be
+	heap-allocated (or NULL if they are not known or not applicable).
+	The meaning of the individual context fields is the same as
+	their counterparts in the helper protocol; see the section below
+	for a description of each field.
++
+The `helpers` member of the struct is a `string_list` of helpers.  Each
+string specifies an external helper which will be run, in order, to
+either acquire or store credentials. See the section on credential
+helpers below.
++
+This struct should always be initialized with `CREDENTIAL_INIT` or
+`credential_init`.
+
+
+Functions
+---------
+
+`credential_init`::
+
+	Initialize a credential structure, setting all fields to empty.
+
+`credential_clear`::
+
+	Free any resources associated with the credential structure,
+	returning it to a pristine initialized state.
+
+`credential_fill`::
+
+	Instruct the credential subsystem to fill the username and
+	password fields of the passed credential struct by first
+	consulting helpers, then asking the user. After this function
+	returns, the username and password fields of the credential are
+	guaranteed to be non-NULL. If an error occurs, the function will
+	die().
+
+`credential_reject`::
+
+	Inform the credential subsystem that the provided credentials
+	have been rejected. This will cause the credential subsystem to
+	notify any helpers of the rejection (which allows them, for
+	example, to purge the invalid credentials from storage).  It
+	will also free() the username and password fields of the
+	credential and set them to NULL (readying the credential for
+	another call to `credential_fill`). Any errors from helpers are
+	ignored.
+
+`credential_approve`::
+
+	Inform the credential subsystem that the provided credentials
+	were successfully used for authentication.  This will cause the
+	credential subsystem to notify any helpers of the approval, so
+	that they may store the result to be used again.  Any errors
+	from helpers are ignored.
+
+`credential_from_url`::
+
+	Parse a URL into broken-down credential fields.
+
+Example
+-------
+
+The example below shows how the functions of the credential API could be
+used to login to a fictitious "foo" service on a remote host:
+
+-----------------------------------------------------------------------
+int foo_login(struct foo_connection *f)
+{
+	int status;
+	/*
+	 * Create a credential with some context; we don't yet know the
+	 * username or password.
+	 */
+
+	struct credential c = CREDENTIAL_INIT;
+	c.protocol = xstrdup("foo");
+	c.host = xstrdup(f->hostname);
+
+	/*
+	 * Fill in the username and password fields by contacting
+	 * helpers and/or asking the user. The function will die if it
+	 * fails.
+	 */
+	credential_fill(&c);
+
+	/*
+	 * Otherwise, we have a username and password. Try to use it.
+	 */
+	status = send_foo_login(f, c.username, c.password);
+	switch (status) {
+	case FOO_OK:
+		/* It worked. Store the credential for later use. */
+		credential_accept(&c);
+		break;
+	case FOO_BAD_LOGIN:
+		/* Erase the credential from storage so we don't try it
+		 * again. */
+		credential_reject(&c);
+		break;
+	default:
+		/*
+		 * Some other error occured. We don't know if the
+		 * credential is good or bad, so report nothing to the
+		 * credential subsystem.
+		 */
+	}
+
+	/* Free any associated resources. */
+	credential_clear(&c);
+
+	return status;
+}
+-----------------------------------------------------------------------
+
+
+Credential Helpers
+------------------
+
+Credential helpers are programs executed by git to fetch or save
+credentials from and to long-term storage (where "long-term" is simply
+longer than a single git process; e.g., credentials may be stored
+in-memory for a few minutes, or indefinitely on disk).
+
+Each helper is specified by a single string. The string is transformed
+by git into a command to be executed using these rules:
+
+  1. If the helper string begins with "!", it is considered a shell
+     snippet, and everything after the "!" becomes the command.
+
+  2. Otherwise, if the helper string begins with an absolute path, the
+     verbatim helper string becomes the command.
+
+  3. Otherwise, the string "git credential-" is prepended to the helper
+     string, and the result becomes the command.
+
+The resulting command then has an "operation" argument appended to it
+(see below for details), and the result is executed by the shell.
+
+Here are some example specifications:
+
+----------------------------------------------------
+# run "git credential-foo"
+foo
+
+# same as above, but pass an argument to the helper
+foo --bar=baz
+
+# the arguments are parsed by the shell, so use shell
+# quoting if necessary
+foo --bar="whitespace arg"
+
+# you can also use an absolute path, which will not use the git wrapper
+/path/to/my/helper --with-arguments
+
+# or you can specify your own shell snippet
+!f() { echo "password=`cat $HOME/.secret`"; }; f
+----------------------------------------------------
+
+Generally speaking, rule (3) above is the simplest for users to specify.
+Authors of credential helpers should make an effort to assist their
+users by naming their program "git-credential-$NAME", and putting it in
+the $PATH or $GIT_EXEC_PATH during installation, which will allow a user
+to enable it with `git config credential.helper $NAME`.
+
+When a helper is executed, it will have one "operation" argument
+appended to its command line, which is one of:
+
+`get`::
+
+	Return a matching credential, if any exists.
+
+`store`::
+
+	Store the credential, if applicable to the helper.
+
+`erase`::
+
+	Remove a matching credential, if any, from the helper's storage.
+
+The details of the credential will be provided on the helper's stdin
+stream. The credential is split into a set of named attributes.
+Attributes are provided to the helper, one per line. Each attribute is
+specified by a key-value pair, separated by an `=` (equals) sign,
+followed by a newline. The key may contain any bytes except `=`,
+newline, or NUL. The value may contain any bytes except newline or NUL.
+In both cases, all bytes are treated as-is (i.e., there is no quoting,
+and one cannot transmit a value with newline or NUL in it). The list of
+attributes is terminated by a blank line or end-of-file.
+
+Git will send the following attributes (but may not send all of
+them for a given credential; for example, a `host` attribute makes no
+sense when dealing with a non-network protocol):
+
+`protocol`::
+
+	The protocol over which the credential will be used (e.g.,
+	`https`).
+
+`host`::
+
+	The remote hostname for a network credential.
+
+`path`::
+
+	The path with which the credential will be used. E.g., for
+	accessing a remote https repository, this will be the
+	repository's path on the server.
+
+`username`::
+
+	The credential's username, if we already have one (e.g., from a
+	URL, from the user, or from a previously run helper).
+
+`password`::
+
+	The credential's password, if we are asking it to be stored.
+
+For a `get` operation, the helper should produce a list of attributes
+on stdout in the same format. A helper is free to produce a subset, or
+even no values at all if it has nothing useful to provide. Any provided
+attributes will overwrite those already known about by git.
+
+For a `store` or `erase` operation, the helper's output is ignored.
+If it fails to perform the requested operation, it may complain to
+stderr to inform the user. If it does not support the requested
+operation (e.g., a read-only store), it should silently ignore the
+request.
+
+If a helper receives any other operation, it should silently ignore the
+request. This leaves room for future operations to be added (older
+helpers will just ignore the new requests).

+Bugs
+----
+
+Because diff-highlight relies on heuristics to guess which parts of
+changes are important, there are some cases where the highlighting is
+more distracting than useful. Fortunately, these cases are rare in
+practice, and when they do occur, the worst case is simply a little
+extra highlighting. This section documents some cases known to be
+sub-optimal, in case somebody feels like working on improving the
+heuristics.
+
+1. Two changes on the same line get highlighted in a blob. For example,
+   highlighting:
+
+----------------------------------------------
+-foo(buf, size);
++foo(obj->buf, obj->size);
+----------------------------------------------
+
+   yields (where the inside of "+{}" would be highlighted):
+
+----------------------------------------------
+-foo(buf, size);
++foo(+{obj->buf, obj->}size);
+----------------------------------------------

+-foo(buf, size);
++foo(+{obj->}buf, +{obj->}size);

+
+   Note that doing this right would probably involve a set of
+   content-specific boundary patterns, similar to word-diff. Otherwise
+   you get junk like:
+
+-----------------------------------------------------
+-this line has some -{i}nt-{ere}sti-{ng} text on it
++this line has some +{fa}nt+{a}sti+{c} text on it
+-----------------------------------------------------
+
+   which is less readable than the current output.
+
+2. The multi-line matching assumes that lines in the pre- and post-image
+   match by position. This is often the case, but can be fooled when a
+   line is removed from the top and a new one added at the bottom (or
+   vice versa). Unless the lines in the middle are also changed, diffs
+   will show this as two hunks, and it will not get highlighted at all
+   (which is good). But if the lines in the middle are changed, the
+   highlighting can be misleading. Here's a pathological case:
+
+-----------------------------------------------------
+-one
+-two
+-three
+-four
++two 2
++three 3
++four 4
++five 5
+-----------------------------------------------------
+
+   which gets highlighted as:
+
+-----------------------------------------------------
+-one
+-t-{wo}
+-three
+-f-{our}
++two 2
++t+{hree 3}
++four 4
++f+{ive 5}
+-----------------------------------------------------
+
+   because it matches "two" to "three 3", and so forth. It would be
+   nicer as:
+
+-----------------------------------------------------
+-one
+-two
+-three
+-four
++two +{2}
++three +{3}
++four +{4}
++five 5
+-----------------------------------------------------
+
+   which would probably involve pre-matching the lines into pairs
+   according to some heuristic.

+The git-diffall script provides a directory based diff mechanism
+for git.
+
+To determine what diff viewer is used, the script requires either
+the 'diff.tool' or 'merge.tool' configuration option to be set.
+
+This script is compatible with most common forms used to specify a
+range of revisions to diff:
+
+  1. git diffall: shows diff between working tree and staged changes
+  2. git diffall --cached [<commit>]: shows diff between staged
+     changes and HEAD (or other named commit)
+  3. git diffall <commit>: shows diff between working tree and named
+     commit
+  4. git diffall <commit> <commit>: show diff between two named commits
+  5. git diffall <commit>..<commit>: same as above
+  6. git diffall <commit>...<commit>: show the changes on the branch
+     containing and up to the second, starting at a common ancestor
+     of both <commit>
+
+Note: all forms take an optional path limiter [-- <path>*]
+
+The '--extcmd=<command>' option allows the user to specify a custom
+command for viewing diffs.  When given, configured defaults are
+ignored and the script runs $command $LOCAL $REMOTE.  Additionally,
+$BASE is set in the environment.
+
+This script is based on an example provided by Thomas Rast on the
+Git list [1]:
+

-git-p4 - Perforce <-> Git converter using git-fast-import
-
-Usage
-=====
-
-git-p4 can be used in two different ways:
-
-1) To import changes from Perforce to a Git repository, using "git-p4 sync".
-
-2) To submit changes from Git back to Perforce, using "git-p4 submit".
-
-Importing
-=========
-
-Simply start with
-
-  git-p4 clone //depot/path/project
-
-or
-
-  git-p4 clone //depot/path/project myproject
-
-This will:
-
-1) Create an empty git repository in a subdirectory called "project" (or
-"myproject" with the second command)
-
-2) Import the head revision from the given Perforce path into a git branch
-called "p4" (remotes/p4 actually)
-
-3) Create a master branch based on it and check it out.
-
-If you want the entire history (not just the head revision) then you can simply
-append a "@all" to the depot path:
-
-  git-p4 clone //depot/project/main@all myproject
-
-
-
-If you want more control you can also use the git-p4 sync command directly:
-
-  mkdir repo-git
-  cd repo-git
-  git init
-  git-p4 sync //path/in/your/perforce/depot
-
-This will import the current head revision of the specified depot path into a
-"remotes/p4/master" branch of your git repository. You can use the
---branch=mybranch option to import into a different branch.
-
-If you want to import the entire history of a given depot path simply use:
-
-  git-p4 sync //path/in/depot@all
-
-
-Note:
-
-To achieve optimal compression you may want to run 'git repack -a -d -f' after
-a big import. This may take a while.
-
-Incremental Imports
-===================
-
-After an initial import you can continue to synchronize your git repository
-with newer changes from the Perforce depot by just calling
-
-  git-p4 sync
-
-in your git repository. By default the "remotes/p4/master" branch is updated.
-
-Advanced Setup
-==============
-
-Suppose you have a periodically updated git repository somewhere, containing a
-complete import of a Perforce project. This repository can be cloned and used
-with git-p4. When updating the cloned repository with the "sync" command,
-git-p4 will try to fetch changes from the original repository first. The git
-protocol used with this is usually faster than importing from Perforce
-directly.
-
-This behaviour can be disabled by setting the "git-p4.syncFromOrigin" git
-configuration variable to "false".
-
-Updating
-========
-
-A common working pattern is to fetch the latest changes from the Perforce depot
-and merge them with local uncommitted changes. The recommended way is to use
-git's rebase mechanism to preserve linear history. git-p4 provides a convenient
-
-  git-p4 rebase
-
-command that calls git-p4 sync followed by git rebase to rebase the current
-working branch.
-
-Submitting
-==========
-
-git-p4 has support for submitting changes from a git repository back to the
-Perforce depot. This requires a Perforce checkout separate from your git
-repository. To submit all changes that are in the current git branch but not in
-the "p4" branch (or "origin" if "p4" doesn't exist) simply call
-
-    git-p4 submit
-
-in your git repository. If you want to submit changes in a specific branch that
-is not your current git branch you can also pass that as an argument:
-
-    git-p4 submit mytopicbranch
-
-You can override the reference branch with the --origin=mysourcebranch option.
-
-The Perforce changelists will be created with the user who ran git-p4. If you
-use --preserve-user then git-p4 will attempt to create Perforce changelists
-with the Perforce user corresponding to the git commit author. You need to
-have sufficient permissions within Perforce, and the git users need to have
-Perforce accounts. Permissions can be granted using 'p4 protect'.
-
-If a submit fails you may have to "p4 resolve" and submit manually. You can
-continue importing the remaining changes with
-
-  git-p4 submit --continue
-
-Example
-=======
-
-# Clone a repository
-  git-p4 clone //depot/path/project
-# Enter the newly cloned directory
-  cd project
-# Do some work...
-  vi foo.h
-# ... and commit locally to gi
-  git commit foo.h
-# In the meantime somebody submitted changes to the Perforce depot. Rebase your latest
-# changes against the latest changes in Perforce:
-  git-p4 rebase
-# Submit your locally committed changes back to Perforce
-  git-p4 submit
-# ... and synchronize with Perforce
-  git-p4 rebase
-
-
-Configuration parameters
-========================
-
-git-p4.user ($P4USER)
-
-Allows you to specify the username to use to connect to the Perforce repository.
-
-  git config [--global] git-p4.user public
-
-git-p4.password ($P4PASS)
-
-Allows you to specify the password to use to connect to the Perforce repository.
-Warning this password will be visible on the command-line invocation of the p4 binary.
-
-  git config [--global] git-p4.password public1234
-
-git-p4.port ($P4PORT)
-
-Specify the port to be used to contact the Perforce server. As this will be passed
-directly to the p4 binary, it may be in the format host:port as well.
-
-  git config [--global] git-p4.port codes.zimbra.com:2666
-
-git-p4.host ($P4HOST)
-
-Specify the host to contact for a Perforce repository.
-
-  git config [--global] git-p4.host perforce.example.com
-
-git-p4.client ($P4CLIENT)
-
-Specify the client name to use
-
-  git config [--global] git-p4.client public-view
-
-git-p4.allowSubmit
-
-  git config [--global] git-p4.allowSubmit false
-
-git-p4.syncFromOrigin
-
-A useful setup may be that you have a periodically updated git repository
-somewhere that contains a complete import of a Perforce project. That git
-repository can be used to clone the working repository from and one would
-import from Perforce directly after cloning using git-p4. If the connection to
-the Perforce server is slow and the working repository hasn't been synced for a
-while it may be desirable to fetch changes from the origin git repository using
-the efficient git protocol. git-p4 supports this setup by calling "git fetch origin"
-by default if there is an origin branch. You can disable this using:
-
-  git config [--global] git-p4.syncFromOrigin false
-
-git-p4.useclientspec
-
-  git config [--global] git-p4.useclientspec false
-
-The P4CLIENT environment variable should be correctly set for p4 to be
-able to find the relevant client.  This client spec will be used to
-both filter the files cloned by git and set the directory layout as
-specified in the client (this implies --keep-path style semantics).
-
-git-p4.skipSubmitModTimeCheck
-
-  git config [--global] git-p4.skipSubmitModTimeCheck false
-
-If true, submit will not check if the p4 change template has been modified.
-
-git-p4.preserveUser
-
-  git config [--global] git-p4.preserveUser false
-
-If true, attempt to preserve user names by modifying the p4 changelists. See
-the "--preserve-user" submit option.
-
-git-p4.allowMissingPerforceUsers
-
-  git config [--global] git-p4.allowMissingP4Users false
-
-If git-p4 is setting the perforce user for a commit (--preserve-user) then
-if there is no perforce user corresponding to the git author, git-p4 will
-stop. With allowMissingPerforceUsers set to true, git-p4 will use the
-current user (i.e. the behavior without --preserve-user) and carry on with
-the perforce commit.
-
-git-p4.skipUserNameCheck
-
-  git config [--global] git-p4.skipUserNameCheck false
-
-When submitting, git-p4 checks that the git commits are authored by the current
-p4 user, and warns if they are not. This disables the check.
-
-git-p4.detectRenames
-
-Detect renames when submitting changes to Perforce server. Will enable -M git
-argument. Can be optionally set to a number representing the threshold
-percentage value of the rename detection.
-
-  git config [--global] git-p4.detectRenames true
-  git config [--global] git-p4.detectRenames 50
-
-git-p4.detectCopies
-
-Detect copies when submitting changes to Perforce server. Will enable -C git
-argument. Can be optionally set to a number representing the threshold
-percentage value of the copy detection.
-
-  git config [--global] git-p4.detectCopies true
-  git config [--global] git-p4.detectCopies 80
-
-git-p4.detectCopiesHarder
-
-Detect copies even between files that did not change when submitting changes to
-Perforce server. Will enable --find-copies-harder git argument.
-
-  git config [--global] git-p4.detectCopies true
-
-git-p4.branchUser
-
-Only use branch specifications defined by the selected username.
-
-  git config [--global] git-p4.branchUser username
-
-git-p4.branchList
-
-List of branches to be imported when branch detection is enabled.
-
-  git config [--global] git-p4.branchList main:branchA
-  git config [--global] --add git-p4.branchList main:branchB
-
-Implementation Details...
-=========================
-
-* Changesets from Perforce are imported using git fast-import.
-* The import does not require anything from the Perforce client view as it just uses
-  "p4 print //depot/path/file#revision" to get the actual file contents.
-* Every imported changeset has a special [git-p4...] line at the
-  end of the log message that gives information about the corresponding
-  Perforce change number and is also used by git-p4 itself to find out
-  where to continue importing when doing incremental imports.
-  Basically when syncing it extracts the perforce change number of the
-  latest commit in the "p4" branch and uses "p4 changes //depot/path/...@changenum,#head"
-  to find out which changes need to be imported.
-* git-p4 submit uses "git rev-list" to pick the commits between the "p4" branch
-  and the current branch.
-  The commits themselves are applied using git diff/format-patch ... | git apply

+	   This trick arranges for messages to be emitted in the user's
+	   requested encoding, but avoids setting LC_CTYPE from the
+	   environment for the whole program.
+
+	   This primarily done to avoid a bug in vsnprintf in the GNU C
+	   Library [1]. which triggered a "your vsnprintf is broken" error
+	   on Git's own repository when inspecting v0.99.6~1 under a UTF-8
+	   locale.
+
+	   That commit contains a ISO-8859-1 encoded author name, which
+	   the locale aware vsnprintf(3) won't interpolate in the format
+	   argument, due to mismatch between the data encoding and the
+	   locale.
+
+	   Even if it wasn't for that bug we wouldn't want to use LC_CTYPE at
+	   this point, because it'd require auditing all the code that uses C
+	   functions whose semantics are modified by LC_CTYPE.
+
+	   But only setting LC_MESSAGES as we do creates a problem, since
+	   we declare the encoding of our PO files[2] the gettext
+	   implementation will try to recode it to the user's locale, but
+	   without LC_CTYPE it'll emit something like this on 'git init'
+	   under the Icelandic locale:
+
+	       Bj? til t?ma Git lind ? /hlagh/.git/
+
+	   Gettext knows about the encoding of our PO file, but we haven't
+	   told it about the user's encoding, so all the non-US-ASCII
+	   characters get encoded to question marks.
+
+	   But we're in luck! We can set LC_CTYPE from the environment
+	   only while we call nl_langinfo and
+	   bind_textdomain_codeset. That suffices to tell gettext what
+	   encoding it should emit in, so it'll now say:
+
+	       Bjó til tóma Git lind í /hlagh/.git/
+
+	   And the equivalent ISO-8859-1 string will be emitted under a
+	   ISO-8859-1 locale.
+
+	   With this change way we get the advantages of setting LC_CTYPE
+	   (talk to the user in his language/encoding), without the major
+	   drawbacks (changed semantics for C functions we rely on).
+
+	   However foreign functions using other message catalogs that
+	   aren't using our neat trick will still have a problem, e.g. if
+	   we have to call perror(3):
+
+	   #include <stdio.h>
+	   #include <locale.h>
+	   #include <errno.h>
+
+	   int main(void)
+	   {
+		   setlocale(LC_MESSAGES, "");
+		   setlocale(LC_CTYPE, "C");
+		   errno = ENODEV;
+		   perror("test");
+		   return 0;
+	   }
+
+	   Running that will give you a message with question marks:
+
+	   $ LANGUAGE= LANG=de_DE.utf8 ./test
+	   test: Kein passendes Ger?t gefunden
+
+	   In the long term we should probably see about getting that
+	   vsnprintf bug in glibc fixed, and audit our code so it won't
+	   fall apart under a non-C locale.
+
+	   Then we could simply set LC_CTYPE from the environment, which would
+	   make things like the external perror(3) messages work.
+
+	   See t/t0203-gettext-setlocale-sanity.sh's "gettext.c" tests for
+	   regression tests.
+
+	   1. http://sourceware.org/bugzilla/show_bug.cgi?id=6530

+Core GIT Translations
+=====================
+
+This directory holds the translations for the core of Git. This document
+describes how you can contribute to the effort of enhancing the language
+coverage and maintaining the translation.
+
+The localization (l10n) coordinator, Jiang Xin <worldhello.net@gmail.com>,
+coordinates our localization effort in the l10 coordinator repository:
+
+        https://github.com/git-l10n/git-po/
+
+As a contributor for a language XX, you should first check TEAMS file in
+this directory to see whether a dedicated repository for your language XX
+exists. Fork the dedicated repository and start to work if it exists.
+
+If you are the first contributor for the language XX, please fork this
+repository, prepare and/or update the translated message file po/XX.po
+(described later), and ask the l10n coordinator to pull your work.
+
+If there are multiple contributors for the same language, please first
+coordinate among yourselves and nominate the team leader for your
+language, so that the l10n coordinator only needs to interact with one
+person per language.
+
+The overall data-flow looks like this:
+
+    +-------------------+            +------------------+
+    | Git source code   | ---(1)---> | L10n coordinator |
+    | repository        | <---(4)--- | repository       |
+    +-------------------+            +------------------+
+                                          |      ^
+                                         (2)    (3)
+                                          V      |
+                                     +------------------+
+                                     | Language Team XX |
+                                     +------------------+
+
+ * Translatable strings are marked in the source file.
+ * L10n coordinator pulls from the source (1)
+ * L10n coordinator updates the message template po/git.pot
+ * Language team pulls from L10n coordinator (2)
+ * Language team updates the message file po/XX.po
+ * L10n coordinator pulls from Language team (3)
+ * L10n coordinator asks the result to be pulled (4).
+
+
+Maintaining the po/git.pot file
+-------------------------------
+
+(This is done by the l10n coordinator).
+
+The po/git.pot file contains a message catalog extracted from Git's
+sources. The l10n coordinator maintains it by adding new translations with
+msginit(1), or update existing ones with msgmerge(1).  In order to update
+the Git sources to extract the messages from, the l10n coordinator is
+expected to pull from the main git repository at strategic point in
+history (e.g. when a major release and release candidates are tagged),
+and then run "make pot" at the top-level directory.
+
+Language contributors use this file to prepare translations for their
+language, but they are not expected to modify it.
+
+
+Initializing a XX.po file
+-------------------------
+
+(This is done by the language teams).
+
+If your language XX does not have translated message file po/XX.po yet,
+you add a translation for the first time by running:
+
+    msginit --locale=XX
+
+in the po/ directory, where XX is the locale, e.g. "de", "is", "pt_BR",
+"zh_CN", etc.
+
+Then edit the automatically generated copyright info in your new XX.po
+to be correct, e.g. for Icelandic:
+
+    @@ -1,6 +1,6 @@
+    -# Icelandic translations for PACKAGE package.
+    -# Copyright (C) 2010 THE PACKAGE'S COPYRIGHT HOLDER

+And change references to PACKAGE VERSION in the PO Header Entry to
+just "Git":
+
+    perl -pi -e 's/(?<="Project-Id-Version: )PACKAGE VERSION/Git/' XX.po
+
+Once you are done testing the translation (see below), commit the result
+and ask the l10n coordinator to pull from you.
+
+
+Updating a XX.po file
+---------------------
+
+(This is done by the language teams).
+
+If you are replacing translation strings in an existing XX.po file to
+improve the translation, just edit the file.
+
+If there's an existing XX.po file for your language, but the repository
+of the l10n coordinator has newer po/git.pot file, you would need to first
+pull from the l10n coordinator (see the beginning of this document for its
+URL), and then update the existing translation by running:
+
+    msgmerge --add-location --backup=off -U XX.po git.pot
+
+in the po/ directory, where XX.po is the file you want to update.
+
+Once you are done testing the translation (see below), commit the result
+and ask the l10n coordinator to pull from you.
+
+
+Testing your changes
+--------------------
+
+(This is done by the language teams, after creating or updating XX.po file).
+
+Before you submit your changes go back to the top-level and do:
+
+    make
+
+On systems with GNU gettext (i.e. not Solaris) this will compile your
+changed PO file with `msgfmt --check`, the --check option flags many
+common errors, e.g. missing printf format strings, or translated
+messages that deviate from the originals in whether they begin/end
+with a newline or not.
+
+
+Marking strings for translation
+-------------------------------
+
+(This is done by the core developers).
+
+Before strings can be translated they first have to be marked for
+translation.
+
+Git uses an internationalization interface that wraps the system's
+gettext library, so most of the advice in your gettext documentation
+(on GNU systems `info gettext` in a terminal) applies.
+
+General advice:
+
+ - Don't mark everything for translation, only strings which will be
+   read by humans (the porcelain interface) should be translated.
+
+   The output from Git's plumbing utilities will primarily be read by
+   programs and would break scripts under non-C locales if it was
+   translated. Plumbing strings should not be translated, since
+   they're part of Git's API.
+
+ - Adjust the strings so that they're easy to translate. Most of the
+   advice in `info '(gettext)Preparing Strings'` applies here.
+
+ - If something is unclear or ambiguous you can use a "TRANSLATORS"
+   comment to tell the translators what to make of it. These will be
+   extracted by xgettext(1) and put in the po/*.po files, e.g. from
+   git-am.sh:
+
+       # TRANSLATORS: Make sure to include [y], [n], [e], [v] and [a]
+       # in your translation. The program will only accept English
+       # input at this point.
+       gettext "Apply? [y]es/[n]o/[e]dit/[v]iew patch/[a]ccept all "
+
+   Or in C, from builtin/revert.c:
+
+       /* TRANSLATORS: %s will be "revert" or "cherry-pick" */
+       die(_("%s: Unable to write new index file"), action_name(opts));
+
+We provide wrappers for C, Shell and Perl programs. Here's how they're
+used:
+
+C:
+
+ - Include builtin.h at the top, it'll pull in gettext.h, which
+   defines the gettext interface. Consult with the list if you need to
+   use gettext.h directly.
+
+ - The C interface is a subset of the normal GNU gettext
+   interface. We currently export these functions:
+
+   - _()
+
+    Mark and translate a string. E.g.:
+
+        printf(_("HEAD is now at %s"), hex);
+
+   - Q_()
+
+    Mark and translate a plural string. E.g.:
+
+        printf(Q_("%d commit", "%d commits", number_of_commits));
+
+    This is just a wrapper for the ngettext() function.
+
+   - N_()
+
+    A no-op pass-through macro for marking strings inside static
+    initializations, e.g.:
+
+        static const char *reset_type_names[] = {
+            N_("mixed"), N_("soft"), N_("hard"), N_("merge"), N_("keep"), NULL
+        };
+
+    And then, later:
+
+        die(_("%s reset is not allowed in a bare repository"),
+               _(reset_type_names[reset_type]));
+
+    Here _() couldn't have statically determined what the translation
+    string will be, but since it was already marked for translation
+    with N_() the look-up in the message catalog will succeed.
+
+Shell:
+
+ - The Git gettext shell interface is just a wrapper for
+   gettext.sh. Import it right after git-sh-setup like this:
+
+       . git-sh-setup
+       . git-sh-i18n
+
+   And then use the gettext or eval_gettext functions:
+
+       # For constant interface messages:
+       gettext "A message for the user"; echo
+
+       # To interpolate variables:
+       details="oh noes"
+       eval_gettext "An error occured: \$details"; echo
+
+   In addition we have wrappers for messages that end with a trailing
+   newline. I.e. you could write the above as:
+
+       # For constant interface messages:
+       gettextln "A message for the user"
+
+       # To interpolate variables:
+       details="oh noes"
+       eval_gettextln "An error occured: \$details"
+
+   More documentation about the interface is available in the GNU info
+   page: `info '(gettext)sh'`. Looking at git-am.sh (the first shell
+   command to be translated) for examples is also useful:
+
+       git log --reverse -p --grep=i18n git-am.sh
+
+Perl:
+
+ - The Git::I18N module provides a limited subset of the
+   Locale::Messages functionality, e.g.:
+
+       use Git::I18N;
+       print __("Welcome to Git!\n");
+       printf __("The following error occured: %s\n"), $error;
+
+   Run `perldoc perl/Git/I18N.pm` for more info.
+
+
+Testing marked strings
+----------------------
+
+Even if you've correctly marked porcelain strings for translation
+something in the test suite might still depend on the US English
+version of the strings, e.g. to grep some error message or other
+output.
+
+To smoke out issues like these Git can be compiled with gettext poison
+support, at the top-level:
+
+    make GETTEXT_POISON=YesPlease
+
+That'll give you a git which emits gibberish on every call to
+gettext. It's obviously not meant to be installed, but you should run
+the test suite with it:
+
+    cd t && prove -j 9 ./t[0-9]*.sh
+
+If tests break with it you should inspect them manually and see if
+what you're translating is sane, i.e. that you're not translating
+plumbing output.
+
+If not you should replace calls to grep with test_i18ngrep, or
+test_cmp calls with test_i18ncmp. If that's not enough you can skip
+the whole test by making it depend on the C_LOCALE_OUTPUT
+prerequisite. See existing test files with this prerequisite for
+examples.

 That'll generate a detailed cover report in the "cover_db_html"
 directory, which you can then copy to a webserver, or inspect locally
 in a browser.

-Smoke testing
--------------
-
-The Git test suite has support for smoke testing. Smoke testing is
-when you submit the results of a test run to a central server for
-analysis and aggregation.
-
-Running a smoke tester is an easy and valuable way of contributing to
-Git development, particularly if you have access to an uncommon OS on
-obscure hardware.
-
-After building Git you can generate a smoke report like this in the
-"t" directory:
-
-    make clean smoke
-
-You can also pass arguments via the environment. This should make it
-faster:
-
-    GIT_TEST_OPTS='--root=/dev/shm' TEST_JOBS=10 make clean smoke
-
-The "smoke" target will run the Git test suite with Perl's
-"TAP::Harness" module, and package up the results in a .tar.gz archive
-with "TAP::Harness::Archive". The former is included with Perl v5.10.1
-or later, but you'll need to install the latter from the CPAN. See the
-"Test coverage" section above for how you might do that.
-
-Once the "smoke" target finishes you'll see a message like this:
-
-    TAP Archive created at <path to git>/t/test-results/git-smoke.tar.gz
-
-To upload the smoke report you need to have curl(1) installed, then
-do:
-
-    make smoke_report
-
-To upload the report anonymously. Hopefully that'll return something
-like "Reported #7 added.".
-
-If you're going to be uploading reports frequently please request a
-user account by E-Mailing gitsmoke@v.nix.is. Once you have a username
-and password you'll be able to do:
-
-    SMOKE_USERNAME=<username> SMOKE_PASSWORD=<password> make smoke_report
-
-You can also add an additional comment to attach to the report, and/or
-a comma separated list of tags:
-
-    SMOKE_USERNAME=<username> SMOKE_PASSWORD=<password> \
-        SMOKE_COMMENT=<comment> SMOKE_TAGS=<tags> \
-        make smoke_report
-
-Once the report is uploaded it'll be made available at
-http://smoke.git.nix.is, here's an overview of Recent Smoke Reports
-for Git:
-
-    http://smoke.git.nix.is/app/projects/smoke_reports/1
-
-The reports will also be mirrored to GitHub every few hours:
-
-    http://github.com/gitsmoke/smoke-reports
-
-The Smolder SQLite database is also mirrored and made available for
-download:
-
-    http://github.com/gitsmoke/smoke-database
-
-Note that the database includes hashed (with crypt()) user passwords
-and E-Mail addresses. Don't use a valuable password for the smoke
-service if you have an account, or an E-Mail address you don't want to
-be publicly known. The user accounts are just meant to be convenient
-labels, they're not meant to be secure.

+Git performance tests
+=====================
+
+This directory holds performance testing scripts for git tools.  The
+first part of this document describes the various ways in which you
+can run them.
+
+When fixing the tools or adding enhancements, you are strongly
+encouraged to add tests in this directory to cover what you are
+trying to fix or enhance.  The later part of this short document
+describes how your test scripts should be organized.
+
+
+Running Tests
+-------------
+
+The easiest way to run tests is to say "make".  This runs all
+the tests on the current git repository.
+
+    === Running 2 tests in this tree ===
+    [...]
+    Test                                     this tree
+    ---------------------------------------------------------
+    0001.1: rev-list --all                   0.54(0.51+0.02)
+    0001.2: rev-list --all --objects         6.14(5.99+0.11)
+    7810.1: grep worktree, cheap regex       0.16(0.16+0.35)
+    7810.2: grep worktree, expensive regex   7.90(29.75+0.37)
+    7810.3: grep --cached, cheap regex       3.07(3.02+0.25)
+    7810.4: grep --cached, expensive regex   9.39(30.57+0.24)
+
+You can compare multiple repositories and even git revisions with the
+'run' script:
+
+    $ ./run . origin/next /path/to/git-tree p0001-rev-list.sh
+
+where . stands for the current git tree.  The full invocation is
+
+    ./run [<revision|directory>...] [--] [<test-script>...]
+
+A '.' argument is implied if you do not pass any other
+revisions/directories.
+
+You can also manually test this or another git build tree, and then
+call the aggregation script to summarize the results:
+
+    $ ./p0001-rev-list.sh
+    [...]
+    $ GIT_BUILD_DIR=/path/to/other/git ./p0001-rev-list.sh
+    [...]
+    $ ./aggregate.perl . /path/to/other/git ./p0001-rev-list.sh
+
+aggregate.perl has the same invocation as 'run', it just does not run
+anything beforehand.
+
+You can set the following variables (also in your config.mak):
+
+    GIT_PERF_REPEAT_COUNT
+	Number of times a test should be repeated for best-of-N
+	measurements.  Defaults to 5.
+
+    GIT_PERF_MAKE_OPTS
+	Options to use when automatically building a git tree for
+	performance testing.  E.g., -j6 would be useful.
+
+    GIT_PERF_REPO
+    GIT_PERF_LARGE_REPO
+	Repositories to copy for the performance tests.  The normal
+	repo should be at least git.git size.  The large repo should
+	probably be about linux-2.6.git size for optimal results.
+	Both default to the git.git you are running from.
+
+You can also pass the options taken by ordinary git tests; the most
+useful one is:
+
+--root=<directory>::
+	Create "trash" directories used to store all temporary data during
+	testing under <directory>, instead of the t/ directory.
+	Using this option with a RAM-based filesystem (such as tmpfs)
+	can massively speed up the test suite.
+
+
+Naming Tests
+------------
+
+The performance test files are named as:
+
+	pNNNN-commandname-details.sh
+
+where N is a decimal digit.  The same conventions for choosing NNNN as
+for normal tests apply.
+
+
+Writing Tests
+-------------
+
+The perf script starts much like a normal test script, except it
+sources perf-lib.sh:
+
+	#!/bin/sh
+	#
+	# Copyright (c) 2005 Junio C Hamano
+	#
+
+	test_description='xxx performance test'
+	. ./perf-lib.sh
+
+After that you will want to use some of the following:
+
+	test_perf_default_repo  # sets up a "normal" repository
+	test_perf_large_repo    # sets up a "large" repository
+
+	test_perf_default_repo sub  # ditto, in a subdir "sub"
+
+        test_checkout_worktree  # if you need the worktree too
+
+At least one of the first two is required!
+
+You can use test_expect_success as usual.  For actual performance
+tests, use
+
+	test_perf 'descriptive string' '
+		command1 &&
+		command2
+	'
+
+test_perf spawns a subshell, for lack of better options.  This means
+that
+
+* you _must_ export all variables that you need in the subshell
+
+* you _must_ flag all variables that you want to persist from the
+  subshell with 'test_export':
+
+	test_perf 'descriptive string' '
+		foo=$(git rev-parse HEAD) &&
+		test_export foo
+	'
+
+  The so-exported variables are automatically marked for export in the
+  shell executing the perf test.  For your convenience, test_export is
+  the same as export in the main shell.
+
+  This feature relies on a bit of magic using 'set' and 'source'.
+  While we have tried to make sure that it can cope with embedded

-The facilities are designed so that one could teach Git without
-too much trouble to store the information needed for these keys to
-remain valid over multiple executions.
-
-Functions
----------
-
-pool_intern::
-	Include a string in the string pool and get its key.
-	If that string is already in the pool, retrieves its
-	existing key.
-
-pool_fetch::
-	Retrieve the string associated to a given key.
-
-pool_tok_r::
-	Extract the key of the next token from a string.
-	Interface mimics strtok_r.
-
-pool_print_seq::
-	Print a sequence of strings named by key to a file, using the
-	specified delimiter to separate them.
-
-	If NULL (key ~0) appears in the sequence, the sequence ends
-	early.
-
-pool_tok_seq::
-	Split a string into tokens, storing the keys of segments
-	into a caller-provided array.
-
-	Unless sz is 0, the array will always be ~0-terminated.
-	If there is not enough room for all the tokens, the
-	array holds as many tokens as fit in the entries before
-	the terminating ~0.  Return value is the index after the
-	last token, or sz if the tokens did not fit.
-
-pool_reset::
-	Deallocate storage for the string pool.

-Motivation
-==========
-
-Treaps provide a memory-efficient binary search tree structure.
-Insertion/deletion/search are about as about as fast in the average
-case as red-black trees and the chances of worst-case behavior are
-vanishingly small, thanks to (pseudo-)randomness.  The bad worst-case
-behavior is a small price to pay, given that treaps are much simpler
-to implement.
-
-API
-===
-
-The trp API generates a data structure and functions to handle a
-large growing set of objects stored in a pool.
-
-The caller:
-
-. Specifies parameters for the generated functions with the
-  trp_gen(static, foo_, ...) macro.
-
-. Allocates a `struct trp_root` variable and sets it to {~0}.
-
-. Adds new nodes to the set using `foo_insert`.  Any pointers
-  to existing nodes cannot be relied upon any more, so the caller
-  might retrieve them anew with `foo_pointer`.
-
-. Can find a specific item in the set using `foo_search`.
-
-. Can iterate over items in the set using `foo_first` and `foo_next`.
-
-. Can remove an item from the set using `foo_remove`.
-
-Example:
-
-----
-struct ex_node {
-	const char *s;
-	struct trp_node ex_link;
-};
-static struct trp_root ex_base = {~0};
-obj_pool_gen(ex, struct ex_node, 4096);
-trp_gen(static, ex_, struct ex_node, ex_link, ex, strcmp)
-struct ex_node *item;
-
-item = ex_pointer(ex_alloc(1));
-item->s = "hello";
-ex_insert(&ex_base, item);
-item = ex_pointer(ex_alloc(1));
-item->s = "goodbye";
-ex_insert(&ex_base, item);
-for (item = ex_first(&ex_base); item; item = ex_next(&ex_base, item))
-	printf("%s\n", item->s);
-----

-Functions
----------
-
-trp_gen(attr, foo_, node_type, link_field, pool, cmp)::
-
-	Generate a type-specific treap implementation.
-+
-. The storage class for generated functions will be 'attr' (e.g., `static`).
-. Generated function names are prefixed with 'foo_' (e.g., `treap_`).
-. Treap nodes will be of type 'node_type' (e.g., `struct treap_node`).
-  This type must be a struct with at least one `struct trp_node` field
-  to point to its children.
-. The field used to access child nodes will be 'link_field'.
-. All treap nodes must lie in the 'pool' object pool.
-. Treap nodes must be totally ordered by the 'cmp' relation, with the
-  following prototype:
-+
-int (*cmp)(node_type \*a, node_type \*b)
-+
-and returning a value less than, equal to, or greater than zero
-according to the result of comparison.
-
-node_type {asterisk}foo_insert(struct trp_root *treap, node_type \*node)::
-
-	Insert node into treap.  If inserted multiple times,
-	a node will appear in the treap multiple times.
-+
-The return value is the address of the node within the treap,
-which might differ from `node` if `pool_alloc` had to call
-`realloc` to expand the pool.
-
-void foo_remove(struct trp_root *treap, node_type \*node)::
-
-	Remove node from treap.  Caller must ensure node is
-	present in treap before using this function.
-
-node_type *foo_search(struct trp_root \*treap, node_type \*key)::
-
-	Search for a node that matches key.  If no match is found,
-	result is NULL.
-
-node_type *foo_nsearch(struct trp_root \*treap, node_type \*key)::
-
-	Like `foo_search`, but if the key is missing return what
-	would be key's successor, were key in treap (NULL if no
-	successor).
-
-node_type *foo_first(struct trp_root \*treap)::
-
-	Find the first item from the treap, in sorted order.
-
-node_type *foo_next(struct trp_root \*treap, node_type \*node)::
-
-	Find the next item.
