+Git v1.9.0 Release Notes
+========================
+
+Backward compatibility notes
+----------------------------
+
+"git submodule foreach $cmd $args" used to treat "$cmd $args" the same
+way "ssh" did, concatenating them into a single string and letting the
+shell unquote. Careless users who forget to sufficiently quote $args
+get their argument split at $IFS whitespaces by the shell, and got
+unexpected results due to this. Starting from this release, the
+command line is passed directly to the shell, if it has an argument.
+
+Read-only support for experimental loose-object format, in which users
+could optionally choose to write their loose objects for a short
+while between v1.4.3 and v1.5.3 era, has been dropped.
+
+The meanings of the "--tags" option to "git fetch" has changed; the
+command fetches tags _in addition to_ what is fetched by the same
+command line without the option.
+
+The way "git push $there $what" interprets the $what part given on the
+command line, when it does not have a colon that explicitly tells us
+what ref at the $there repository is to be updated, has been enhanced.
+
+A handful of ancient commands that have long been deprecated are
+finally gone (repo-config, tar-tree, lost-found, and peek-remote).
+
+
+Backward compatibility notes (for Git 2.0.0)
+--------------------------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there). In Git 2.0, the default will change to the "simple"
+semantics, which pushes:
+
+ - only the current branch to the branch with the same name, and only
+ when the current branch is set to integrate with that remote
+ branch, if you are pushing to the same remote as you fetch from; or
+
+ - only the current branch to the branch with the same name, if you
+ are pushing to a remote that is not where you usually fetch from.
+
+Use the user preference configuration variable "push.default" to
+change this. If you are an old-timer who is used to the "matching"
+semantics, you can set the variable to "matching" to keep the
+traditional behaviour. If you want to live in the future early, you
+can set it to "simple" today without waiting for Git 2.0.
+
+When "git add -u" (and "git add -A") is run inside a subdirectory and
+does not specify which paths to add on the command line, it
+will operate on the entire tree in Git 2.0 for consistency
+with "git commit -a" and other commands. There will be no
+mechanism to make plain "git add -u" behave like "git add -u .".
+Current users of "git add -u" (without a pathspec) should start
+training their fingers to explicitly say "git add -u ."
+before Git 2.0 comes. A warning is issued when these commands are
+run without a pathspec and when you have local changes outside the
+current directory, because the behaviour in Git 2.0 will be different
+from today's version in such a situation.
+
+In Git 2.0, "git add <path>" will behave as "git add -A <path>", so
+that "git add dir/" will notice paths you removed from the directory
+and record the removal. Versions before Git 2.0, including this
+release, will keep ignoring removals, but the users who rely on this
+behaviour are encouraged to start using "git add --ignore-removal <path>"
+now before 2.0 is released.
+
+The default prefix for "git svn" will change in Git 2.0. For a long
+time, "git svn" created its remote-tracking branches directly under
+refs/remotes, but it will place them under refs/remotes/origin/ unless
+it is told otherwise with its --prefix option.
+
+
+Updates since v1.8.5
+--------------------
+
+Foreign interfaces, subsystems and ports.
+
+ * The HTTP transport, when talking GSS-Negotiate, uses "100
+ Continue" response to avoid having to rewind and resend a large
+ payload, which may not be always doable.
+
+ * Various bugfixes to remote-bzr and remote-hg (in contrib/).
+
+ * The build procedure is aware of MirBSD now.
+
+ * Various "git p4", "git svn" and "gitk" updates.
+
+
+UI, Workflows & Features
+
+ * Fetching from a shallowly-cloned repository used to be forbidden,
+ primarily because the codepaths involved were not carefully vetted
+ and we did not bother supporting such usage. This release attempts
+ to allow object transfer out of a shallowly-cloned repository in a
+ more controlled way (i.e. the receiver becomes a shallow repository
+ with a truncated history).
+
+ * Just like we give a reasonable default for "less" via the LESS
+ environment variable, we now specify a reasonable default for "lv"
+ via the "LV" environment variable when spawning the pager.
+
+ * Two-level configuration variable names in "branch.*" and "remote.*"
+ hierarchies, whose variables are predominantly three-level, were
+ not completed by hitting a <TAB> in bash and zsh completions.
+
+ * Fetching a 'frotz' branch with "git fetch", while a 'frotz/nitfol'
+ remote-tracking branch from an earlier fetch was still there, would
+ error out, primarily because the command was not told that it is
+ allowed to lose any information on our side. "git fetch --prune"
+ now can be used to remove 'frotz/nitfol' to make room for fetching and
+ storing the 'frotz' remote-tracking branch.
+
+ * "diff.orderfile=<file>" configuration variable can be used to
+ pretend as if the "-O<file>" option were given from the command
+ line of "git diff", etc.
+
+ * The negative pathspec syntax allows "git log -- . ':!dir'" to tell
+ us "I am interested in everything but 'dir' directory".
+
+ * "git difftool" shows how many different paths there are in total,
+ and how many of them have been shown so far, to indicate progress.
+
+ * "git push origin master" used to push our 'master' branch to update
+ the 'master' branch at the 'origin' repository. This has been
+ enhanced to use the same ref mapping "git push origin" would use to
+ determine what ref at the 'origin' to be updated with our 'master'.
+ For example, with this configuration
+
+ [remote "origin"]
+ push = refs/heads/*:refs/review/*
+
+ that would cause "git push origin" to push out our local branches
+ to corresponding refs under refs/review/ hierarchy at 'origin',
+ "git push origin master" would update 'refs/review/master' over
+ there. Alternatively, if push.default is set to 'upstream' and our
+ 'master' is set to integrate with 'topic' from the 'origin' branch,
+ running "git push origin" while on our 'master' would update their
+ 'topic' branch, and running "git push origin master" while on any
+ of our branches does the same.
+
+ * "gitweb" learned to treat ref hierarchies other than refs/heads as
+ if they are additional branch namespaces (e.g. refs/changes/ in
+ Gerrit).
+
+ * "git for-each-ref --format=..." learned a few formatting directives;
+ e.g. "%(color:red)%(HEAD)%(color:reset) %(refname:short) %(subject)".
+
+ * The command string given to "git submodule foreach" is passed
+ directly to the shell, without being eval'ed. This is a backward
+ incompatible change that may break existing users.
+
+ * "git log" and friends learned the "--exclude=<glob>" option, to
+ allow people to say "list history of all branches except those that
+ match this pattern" with "git log --exclude='*/*' --branches".
+
+ * "git rev-parse --parseopt" learned a new "--stuck-long" option to
+ help scripts parse options with an optional parameter.
+
+ * The "--tags" option to "git fetch" no longer tells the command to
+ fetch _only_ the tags. It instead fetches tags _in addition to_
+ what are fetched by the same command line without the option.
+
+
+Performance, Internal Implementation, etc.
+
+ * When parsing a 40-hex string into the object name, the string is
+ checked to see if it can be interpreted as a ref so that a warning
+ can be given for ambiguity. The code kicked in even when the
+ core.warnambiguousrefs is set to false to squelch this warning, in
+ which case the cycles spent to look at the ref namespace were an
+ expensive no-op, as the result was discarded without being used.
+
+ * The naming convention of the packfiles has been updated; it used to
+ be based on the enumeration of names of the objects that are
+ contained in the pack, but now it also depends on how the packed
+ result is represented---packing the same set of objects using
+ different settings (or delta order) would produce a pack with
+ different name.
+
+ * "git diff --no-index" mode used to unnecessarily attempt to read
+ the index when there is one.
+
+ * The deprecated parse-options macro OPT_BOOLEAN has been removed;
+ use OPT_BOOL or OPT_COUNTUP in new code.
+
+ * A few duplicate implementations of prefix/suffix string comparison
+ functions have been unified to starts_with() and ends_with().
+
+ * The new PERLLIB_EXTRA makefile variable can be used to specify
+ additional directories Perl modules (e.g. the ones necessary to run
+ git-svn) are installed on the platform when building.
+
+ * "git merge-base" learned the "--fork-point" mode, that implements
+ the same logic used in "git pull --rebase" to find a suitable fork
+ point out of the reflog entries for the remote-tracking branch the
+ work has been based on. "git rebase" has the same logic that can be
+ triggered with the "--fork-point" option.
+
+ * A third-party "receive-pack" (the responder to "git push") can
+ advertise the "no-thin" capability to tell "git push" not to use
+ the thin-pack optimization. Our receive-pack has always been
+ capable of accepting and fattening a thin-pack, and will continue
+ not to ask "git push" to use a non-thin pack.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v1.8.5
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.5 in the maintenance
+track are contained in this release (see the maintenance releases' notes
+for details).
+
+ * The pathspec matching code, while comparing two trees (e.g. "git
+ diff A B -- path1 path2") was too aggressive and failed to match
+ some paths when multiple pathspecs were involved.
+
+ * "git repack --max-pack-size=8g" stopped being parsed correctly when
+ the command was reimplemented in C.
+
+ * An earlier update in v1.8.4.x to "git rev-list --objects" with
+ negative ref had a performance regression.
+ (merge 200abe7 jk/mark-edges-uninteresting later to maint).
+
+ * A recent update to "git send-email" broke platforms where
+ /etc/ssl/certs/ directory exists but cannot be used as SSL_ca_path
+ (e.g. Fedora rawhide).
+
+ * A handful of bugs around interpreting $branch@{upstream} notation
+ and its lookalike, when $branch part has interesting characters,
+ e.g. "@", and ":", have been fixed.
+
+ * "git clone" would fail to clone from a repository that has a ref
+ directly under "refs/", e.g. "refs/stash", because different
+ validation paths do different things on such a refname. Loosen the
+ client side's validation to allow such a ref.
+
+ * "git log --left-right A...B" lost the "leftness" of commits
+ reachable from A when A is a tag as a side effect of a recent
+ bugfix. This is a regression in 1.8.4.x series.
+
+ * documentations to "git pull" hinted there is an "-m" option because
+ it incorrectly shared the documentation with "git merge".
+
+ * "git diff A B submod" and "git diff A B submod/" ought to have done
+ the same for a submodule "submod", but didn't.
+
+ * "git clone $origin foo\bar\baz" on Windows failed to create the
+ leading directories (i.e. a moral-equivalent of "mkdir -p").
+
+ * "submodule.*.update=checkout", when propagated from .gitmodules to
+ .git/config, turned into a "submodule.*.update=none", which did not
+ make much sense.
+ (merge efa8fd7 fp/submodule-checkout-mode later to maint).
+
+ * The implementation of 'git stash $cmd "stash@{...}"' did not quote
+ the stash argument properly and left it split at IFS whitespace.
+
+ * The "--[no-]informative-errors" options to "git daemon" were parsed
+ a bit too loosely, allowing any other string after these option
+ names.
+
+ * There is no reason to have a hardcoded upper limit for the number of
+ parents of an octopus merge, created via the graft mechanism, but
+ there was.
+
+ * The basic test used to leave unnecessary trash directories in the
+ t/ directory.
+ (merge 738a8be jk/test-framework-updates later to maint).
+
+ * "git merge-base --octopus" used to leave cleaning up suboptimal
+ result to the caller, but now it does the clean-up itself.
+
+ * A "gc" process running as a different user should be able to stop a
+ new "gc" process from starting, but it didn't.
+
+ * An earlier "clean-up" introduced an unnecessary memory leak.
+
+ * "git add -A" (no other arguments) in a totally empty working tree
+ used to emit an error.
+
+ * "git log --decorate" did not handle a tag pointed by another tag
+ nicely.
+
+ * When we figure out how many file descriptors to allocate for
+ keeping packfiles open, a system with non-working getrlimit() could
+ cause us to die(), but because we make this call only to get a
+ rough estimate of how many are available and we do not even attempt
+ to use up all available file descriptors ourselves, it is nicer to
+ fall back to a reasonable low value rather than dying.
+
+ * read_sha1_file(), that is the workhorse to read the contents given
+ an object name, honoured object replacements, but there was no
+ corresponding mechanism to sha1_object_info() that was used to
+ obtain the metainfo (e.g. type & size) about the object. This led
+ callers to weird inconsistencies.
+ (merge 663a856 cc/replace-object-info later to maint).
+
+ * "git cat-file --batch=", an admittedly useless command, did not
+ behave very well.
+
+ * "git rev-parse <revs> -- <paths>" did not implement the usual
+ disambiguation rules the commands in the "git log" family used in
+ the same way.
+
+ * "git mv A B/", when B does not exist as a directory, should error
+ out, but it didn't.
+
+ * A workaround to an old bug in glibc prior to glibc 2.17 has been
+ retired; this would remove a side effect of the workaround that
+ corrupts system error messages in non-C locales.
+
+ * SSL-related options were not passed correctly to underlying socket
+ layer in "git send-email".
+
+ * "git commit -v" appends the patch to the log message before
+ editing, and then removes the patch when the editor returned
+ control. However, the patch was not stripped correctly when the
+ first modified path was a submodule.
+
+ * "git fetch --depth=0" was a no-op, and was silently ignored.
+ Diagnose it as an error.
+
+ * Remote repository URLs expressed in scp-style host:path notation are
+ parsed more carefully (e.g. "foo/bar:baz" is local, "[::1]:/~user" asks
+ to connect to user's home directory on host at address ::1.
+
+ * "git diff -- ':(icase)makefile'" was unnecessarily rejected at the
+ command line parser.
+
+ * "git cat-file --batch-check=ok" did not check the existence of
+ the named object.
+
+ * "git am --abort" sometimes complained about not being able to write
+ a tree with an 0{40} object in it.
+
+ * Two processes creating loose objects at the same time could have
+ failed unnecessarily when the name of their new objects started
+ with the same byte value, due to a race condition.

+Git v1.9.1 Release Notes
+========================
+
+Fixes since v1.9.0
+------------------
+
+ * "git clean -d pathspec" did not use the given pathspec correctly
+ and ended up cleaning too much.
+
+ * "git difftool" misbehaved when the repository is bound to the
+ working tree with the ".git file" mechanism, where a textual file
+ ".git" tells us where it is.
+
+ * "git push" did not pay attention to branch.*.pushremote if it is
+ defined earlier than remote.pushdefault; the order of these two
+ variables in the configuration file should not matter, but it did
+ by mistake.
+
+ * Codepaths that parse timestamps in commit objects have been
+ tightened.
+
+ * "git diff --external-diff" incorrectly fed the submodule directory
+ in the working tree to the external diff driver when it knew it is
+ the same as one of the versions being compared.
+
+ * "git reset" needs to refresh the index when working in a working
+ tree (it can also be used to match the index to the HEAD in an
+ otherwise bare repository), but it failed to set up the working
+ tree properly, causing GIT_WORK_TREE to be ignored.
+
+ * "git check-attr" when working on a repository with a working tree
+ did not work well when the working tree was specified via the
+ --work-tree (and obviously with --git-dir) option.
+
+ * "merge-recursive" was broken in 1.7.7 era and stopped working in
+ an empty (temporary) working tree, when there are renames
+ involved. This has been corrected.
+
+ * "git rev-parse" was loose in rejecting command line arguments
+ that do not make sense, e.g. "--default" without the required
+ value for that option.
+
+ * include.path variable (or any variable that expects a path that
+ can use ~username expansion) in the configuration file is not a
+ boolean, but the code failed to check it.
+
+ * "git diff --quiet -- pathspec1 pathspec2" sometimes did not return
+ correct status value.
+
+ * Attempting to deepen a shallow repository by fetching over smart
+ HTTP transport failed in the protocol exchange, when no-done
+ extension was used. The fetching side waited for the list of
+ shallow boundary commits after the sending end stopped talking to
+ it.
+
+ * Allow "git cmd path/", when the 'path' is where a submodule is
+ bound to the top-level working tree, to match 'path', despite the
+ extra and unnecessary trailing slash (such a slash is often
+ given by command line completion).

+Git v1.9.2 Release Notes
+========================
+
+Fixes since v1.9.1
+------------------
+
+ * Documentation and in-code comments had many instances of mistaken
+ use of "nor", which have been corrected.
+
+ * "git fetch --prune", when the right-hand-side of multiple fetch
+ refspecs overlap (e.g. storing "refs/heads/*" to
+ "refs/remotes/origin/*", while storing "refs/frotz/*" to
+ "refs/remotes/origin/fr/*"), aggressively thought that lack of
+ "refs/heads/fr/otz" on the origin site meant we should remove
+ "refs/remotes/origin/fr/otz" from us, without checking their
+ "refs/frotz/otz" first.
+
+ Note that such a configuration is inherently unsafe (think what
+ should happen when "refs/heads/fr/otz" does appear on the origin
+ site), but that is not a reason not to be extra careful.
+
+ * "git update-ref --stdin" did not fail a request to create a ref
+ when the ref already existed.
+
+ * "git diff --no-index -Mq a b" fell into an infinite loop.
+
+ * When it is not necessary to edit a commit log message (e.g. "git
+ commit -m" is given a message without specifying "-e"), we used to
+ disable the spawning of the editor by overriding GIT_EDITOR, but
+ this means all the uses of the editor, other than to edit the
+ commit log message, are also affected.
+
+ * "git status --porcelain --branch" showed its output with labels
+ "ahead/behind/gone" translated to the user's locale.
+
+ * "git mv" that moves a submodule forgot to adjust the array that
+ uses to keep track of which submodules were to be moved to update
+ its configuration.
+
+ * Length limit for the pathname used when removing a path in a deep
+ subdirectory has been removed to avoid buffer overflows.
+
+ * The test helper lib-terminal always run an actual test_expect_*
+ when included, which screwed up with the use of skil-all that may
+ have to be done later.
+
+ * "git index-pack" used a wrong variable to name the keep-file in an
+ error message when the file cannot be written or closed.
+
+ * "rebase -i" produced a broken insn sheet when the title of a commit
+ happened to contain '\n' (or ended with '\c') due to a careless use
+ of 'echo'.
+
+ * There were a few instances of 'git-foo' remaining in the
+ documentation that should have been spelled 'git foo'.
+
+ * Serving objects from a shallow repository needs to write a
+ new file to hold the temporary shallow boundaries but it was not
+ cleaned when we exit due to die() or a signal.
+
+ * When "git stash pop" stops after failing to apply the stash
+ (e.g. due to conflicting changes), the stash is not dropped. State
+ that explicitly in the output to let the users know.
+
+ * The labels in "git status" output that describe the nature of
+ conflicts (e.g. "both deleted") were limited to 20 bytes, which was
+ too short for some l10n (e.g. fr).

+Git v2.0 Release Notes
+======================
+
+Backward compatibility notes
+----------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there). In Git 2.0, the default is now the "simple" semantics,
+which pushes:
+
+ - only the current branch to the branch with the same name, and only
+ when the current branch is set to integrate with that remote
+ branch, if you are pushing to the same remote as you fetch from; or
+
+ - only the current branch to the branch with the same name, if you
+ are pushing to a remote that is not where you usually fetch from.
+
+You can use the configuration variable "push.default" to change
+this. If you are an old-timer who wants to keep using the
+"matching" semantics, you can set the variable to "matching", for
+example. Read the documentation for other possibilities.
+
+When "git add -u" and "git add -A" are run inside a subdirectory
+without specifying which paths to add on the command line, they
+operate on the entire tree for consistency with "git commit -a" and
+other commands (these commands used to operate only on the current
+subdirectory). Say "git add -u ." or "git add -A ." if you want to
+limit the operation to the current directory.
+
+"git add <path>" is the same as "git add -A <path>" now, so that
+"git add dir/" will notice paths you removed from the directory and
+record the removal. In older versions of Git, "git add <path>" used
+to ignore removals. You can say "git add --ignore-removal <path>" to
+add only added or modified paths in <path>, if you really want to.
+
+The "-q" option to "git diff-files", which does *NOT* mean "quiet",
+has been removed (it told Git to ignore deletion, which you can do
+with "git diff-files --diff-filter=d").
+
+"git request-pull" lost a few "heuristics" that often led to mistakes.
+
+The default prefix for "git svn" has changed in Git 2.0. For a long
+time, "git svn" created its remote-tracking branches directly under
+refs/remotes, but it now places them under refs/remotes/origin/ unless
+it is told otherwise with its "--prefix" option.
+
+
+Updates since v1.9 series
+-------------------------
+
+UI, Workflows & Features
+
+ * The "multi-mail" post-receive hook (in contrib/) has been updated
+ to a more recent version from upstream.
+
+ * The "remote-hg/bzr" remote-helper interfaces (used to be in
+ contrib/) are no more. They are now maintained separately as
+ third-party plug-ins in their own repositories.
+
+ * "git gc --aggressive" learned "--depth" option and
+ "gc.aggressiveDepth" configuration variable to allow use of a less
+ insane depth than the built-in default value of 250.
+
+ * "git log" learned the "--show-linear-break" option to show where a
+ single strand-of-pearls is broken in its output.
+
+ * The "rev-parse --parseopt" mechanism used by scripted Porcelains to
+ parse command-line options and to give help text learned to take
+ the argv-help (the placeholder string for an option parameter,
+ e.g. "key-id" in "--gpg-sign=<key-id>").
+
+ * The pattern to find where the function begins in C/C++ used in
+ "diff" and "grep -p" has been updated to improve viewing C++
+ sources.
+
+ * "git rebase" learned to interpret a lone "-" as "@{-1}", the
+ branch that we were previously on.
+
+ * "git commit --cleanup=<mode>" learned a new mode, scissors.
+
+ * "git tag --list" output can be sorted using "version sort" with
+ "--sort=version:refname".
+
+ * Discard the accumulated "heuristics" to guess from which branch the
+ result wants to be pulled from and make sure that what the end user
+ specified is not second-guessed by "git request-pull", to avoid
+ mistakes. When you pushed out your 'master' branch to your public
+ repository as 'for-linus', use the new "master:for-linus" syntax to
+ denote the branch to be pulled.
+
+ * "git grep" learned to behave in a way similar to native grep when
+ "-h" (no header) and "-c" (count) options are given.
+
+ * "git push" via transport-helper interface has been updated to
+ allow forced ref updates in a way similar to the natively
+ supported transports.
+
+ * The "simple" mode is the default for "git push".
+
+ * "git add -u" and "git add -A", when run without any pathspec, is a
+ tree-wide operation even when run inside a subdirectory of a
+ working tree.
+
+ * "git add <path>" is the same as "git add -A <path>" now.
+
+ * "core.statinfo" configuration variable, which is a
+ never-advertised synonym to "core.checkstat", has been removed.
+
+ * The "-q" option to "git diff-files", which does *NOT* mean
+ "quiet", has been removed (it told Git to ignore deletion, which
+ you can do with "git diff-files --diff-filter=d").
+
+ * Server operators can loosen the "tips of refs only" restriction for
+ the remote archive service with the uploadarchive.allowUnreachable
+ configuration option.
+
+ * The progress indicators from various time-consuming commands have
+ been marked for i18n/l10n.
+
+ * "git notes -C <blob>" diagnoses as an error an attempt to use an
+ object that is not a blob.
+
+ * "git config" learned to read from the standard input when "-" is
+ given as the value to its "--file" parameter (attempting an
+ operation to update the configuration in the standard input is
+ rejected, of course).
+
+ * Trailing whitespaces in .gitignore files, unless they are quoted
+ for fnmatch(3), e.g. "path\ ", are warned and ignored. Strictly
+ speaking, this is a backward-incompatible change, but very unlikely
+ to bite any sane user and adjusting should be obvious and easy.
+
+ * Many commands that create commits, e.g. "pull" and "rebase",
+ learned to take the "--gpg-sign" option on the command line.
+
+ * "git commit" can be told to always GPG sign the resulting commit
+ by setting the "commit.gpgsign" configuration variable to "true"
+ (the command-line option "--no-gpg-sign" should override it).
+
+ * "git pull" can be told to only accept fast-forward by setting the
+ new "pull.ff" configuration variable.
+
+ * "git reset" learned the "-N" option, which does not reset the index
+ fully for paths the index knows about but the tree-ish the command
+ resets to does not (these paths are kept as intend-to-add entries).
+
+
+Performance, Internal Implementation, etc.
+
+ * The compilation options to port to AIX and to MSVC have been
+ updated.
+
+ * We started using wildmatch() in place of fnmatch(3) a few releases
+ ago; complete the process and stop using fnmatch(3).
+
+ * Uses of curl's "multi" interface and "easy" interface do not mix
+ well when we attempt to reuse outgoing connections. Teach the RPC
+ over HTTP code, used in the smart HTTP transport, not to use the
+ "easy" interface.
+
+ * The bitmap-index feature from JGit has been ported, which should
+ significantly improve performance when serving objects from a
+ repository that uses it.
+
+ * The way "git log --cc" shows a combined diff against multiple
+ parents has been optimized.
+
+ * The prefixcmp() and suffixcmp() functions are gone. Use
+ starts_with() and ends_with(), and also consider if skip_prefix()
+ suits your needs better when using the former.
+
+
+Also contains various documentation updates and code clean-ups. Many
+of them came from flurry of activities as GSoC candidate microproject
+exercises.
+
+
+Fixes since v1.9 series
+-----------------------
+
+Unless otherwise noted, all the fixes since v1.9 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git p4" was broken in 1.9 release to deal with changes in binary
+ files.
+ (merge 749b668 cl/p4-use-diff-tree later to maint).
+
+ * The shell prompt script (in contrib/), when using the PROMPT_COMMAND
+ interface, used an unsafe construct when showing the branch name in
+ $PS1.
+ (merge 1e4119c8 rh/prompt-pcmode-avoid-eval-on-refname later to maint).
+
+ * "git rebase" used a POSIX shell construct FreeBSD's /bin/sh does not
+ work well with.
+ (merge 8cd6596 km/avoid-non-function-return-in-rebase later to maint).
+
+ * zsh prompt (in contrib/) leaked unnecessary error messages.
+
+ * Bash completion (in contrib/) did not complete the refs and remotes
+ correctly given "git pu<TAB>" when "pu" is aliased to "push".
+
+ * Some more Unicode code points, defined in Unicode 6.3 as having zero
+ width, have been taught to our display column counting logic.
+ (merge d813ab9 tb/unicode-6.3-zero-width later to maint).
+
+ * Some tests used shell constructs that did not work well on FreeBSD
+ (merge ff7a1c6 km/avoid-bs-in-shell-glob later to maint).
+ (merge 00764ca km/avoid-cp-a later to maint).
+
+ * "git update-ref --stdin" did not fail a request to create a ref
+ when the ref already existed.
+ (merge b9d56b5 mh/update-ref-batch-create-fix later to maint).
+
+ * "git diff --no-index -Mq a b" fell into an infinite loop.
+ (merge ad1c3fb jc/fix-diff-no-index-diff-opt-parse later to maint).
+
+ * "git fetch --prune", when the right-hand side of multiple fetch
+ refspecs overlap (e.g. storing "refs/heads/*" to
+ "refs/remotes/origin/*", while storing "refs/frotz/*" to
+ "refs/remotes/origin/fr/*"), aggressively thought that lack of
+ "refs/heads/fr/otz" on the origin site meant we should remove
+ "refs/remotes/origin/fr/otz" from us, without checking their
+ "refs/frotz/otz" first.
+
+ Note that such a configuration is inherently unsafe (think what
+ should happen when "refs/heads/fr/otz" does appear on the origin
+ site), but that is not a reason not to be extra careful.
+ (merge e6f6371 cn/fetch-prune-overlapping-destination later to maint).
+
+ * "git status --porcelain --branch" showed its output with labels
+ "ahead/behind/gone" translated to the user's locale.
+ (merge 7a76c28 mm/status-porcelain-format-i18n-fix later to maint).
+
+ * A stray environment variable $prefix could have leaked into and
+ affected the behaviour of the "subtree" script (in contrib/).
+
+ * When it is not necessary to edit a commit log message (e.g. "git
+ commit -m" is given a message without specifying "-e"), we used to
+ disable the spawning of the editor by overriding GIT_EDITOR, but
+ this means all the uses of the editor, other than to edit the
+ commit log message, are also affected.
+ (merge b549be0 bp/commit-p-editor later to maint).
+
+ * "git mv" that moves a submodule forgot to adjust the array that
+ uses to keep track of which submodules were to be moved to update
+ its configuration.
+ (merge fb8a4e8 jk/mv-submodules-fix later to maint).
+
+ * Length limit for the pathname used when removing a path in a deep
+ subdirectory has been removed to avoid buffer overflows.
+ (merge 2f29e0c mh/remove-subtree-long-pathname-fix later to maint).
+
+ * The test helper lib-terminal always run an actual test_expect_*
+ when included, which screwed up with the use of skil-all that may
+ have to be done later.
+ (merge 7e27173 jk/lib-terminal-lazy later to maint).
+
+ * "git index-pack" used a wrong variable to name the keep-file in an
+ error message when the file cannot be written or closed.
+ (merge de983a0 nd/index-pack-error-message later to maint).
+
+ * "rebase -i" produced a broken insn sheet when the title of a commit
+ happened to contain '\n' (or ended with '\c') due to a careless use
+ of 'echo'.
+ (merge cb1aefd us/printf-not-echo later to maint).
+
+ * There were a few instances of 'git-foo' remaining in the
+ documentation that should have been spelled 'git foo'.
+ (merge 3c3e6f5 rr/doc-merge-strategies later to maint).
+
+ * Serving objects from a shallow repository needs to write a
+ new file to hold the temporary shallow boundaries, but it was not
+ cleaned when we exit due to die() or a signal.
+ (merge 7839632 jk/shallow-update-fix later to maint).
+
+ * When "git stash pop" stops after failing to apply the stash
+ (e.g. due to conflicting changes), the stash is not dropped. State
+ that explicitly in the output to let the users know.
+ (merge 2d4c993 jc/stash-pop-not-popped later to maint).
+
+ * The labels in "git status" output that describe the nature of
+ conflicts (e.g. "both deleted") were limited to 20 bytes, which was
+ too short for some l10n (e.g. fr).
+ (merge c7cb333 jn/wt-status later to maint).
+
+ * "git clean -d pathspec" did not use the given pathspec correctly
+ and ended up cleaning too much.
+ (merge 1f2e108 jk/clean-d-pathspec later to maint).
+
+ * "git difftool" misbehaved when the repository is bound to the
+ working tree with the ".git file" mechanism, where a textual file
+ ".git" tells us where it is.
+ (merge fcfec8b da/difftool-git-files later to maint).
+
+ * "git push" did not pay attention to "branch.*.pushremote" if it is
+ defined earlier than "remote.pushdefault"; the order of these two
+ variables in the configuration file should not matter, but it did
+ by mistake.
+ (merge 98b406f jk/remote-pushremote-config-reading later to maint).
+
+ * Code paths that parse timestamps in commit objects have been
+ tightened.
+ (merge f80d1f9 jk/commit-dates-parsing-fix later to maint).
+
+ * "git diff --external-diff" incorrectly fed the submodule directory
+ in the working tree to the external diff driver when it knew that it
+ is the same as one of the versions being compared.
+ (merge aba4727 tr/diff-submodule-no-reuse-worktree later to maint).
+
+ * "git reset" needs to refresh the index when working in a working
+ tree (it can also be used to match the index to the HEAD in an
+ otherwise bare repository), but it failed to set up the working
+ tree properly, causing GIT_WORK_TREE to be ignored.
+ (merge b7756d4 nd/reset-setup-worktree later to maint).
+
+ * "git check-attr" when working on a repository with a working tree
+ did not work well when the working tree was specified via the
+ "--work-tree" (and obviously with "--git-dir") option.
+ (merge cdbf623 jc/check-attr-honor-working-tree later to maint).
+
+ * "merge-recursive" was broken in 1.7.7 era and stopped working in
+ an empty (temporary) working tree, when there are renames
+ involved. This has been corrected.
+ (merge 6e2068a bk/refresh-missing-ok-in-merge-recursive later to maint.)
+
+ * "git rev-parse" was loose in rejecting command-line arguments
+ that do not make sense, e.g. "--default" without the required
+ value for that option.
+ (merge a43219f ds/rev-parse-required-args later to maint.)
+
+ * "include.path" variable (or any variable that expects a path that
+ can use ~username expansion) in the configuration file is not a
+ boolean, but the code failed to check it.
+ (merge 67beb60 jk/config-path-include-fix later to maint.)
+
+ * Commands that take pathspecs on the command line misbehaved when
+ the pathspec is given as an absolute pathname (which is a
+ practice not particularly encouraged) that points at a symbolic
+ link in the working tree.
+ (merge 6127ff6 mw/symlinks later to maint.)
+
+ * "git diff --quiet -- pathspec1 pathspec2" sometimes did not return
+ the correct status value.
+ (merge f34b205 nd/diff-quiet-stat-dirty later to maint.)
+
+ * Attempting to deepen a shallow repository by fetching over smart
+ HTTP transport failed in the protocol exchange, when the no-done
+ extension was used. The fetching side waited for the list of
+ shallow boundary commits after the sending side stopped talking to
+ it.
+ (merge 0232852 nd/http-fetch-shallow-fix later to maint.)
+
+ * Allow "git cmd path/", when the 'path' is where a submodule is
+ bound to the top-level working tree, to match 'path', despite the
+ extra and unnecessary trailing slash (such a slash is often
+ given by command-line completion).
+ (merge 2e70c01 nd/submodule-pathspec-ending-with-slash later to maint.)
+
+ * Documentation and in-code comments had many instances of mistaken
+ use of "nor", which have been corrected.
+ (merge 235e8d5 jl/nor-or-nand-and later to maint).

+Git v2.1 Release Notes
+======================
+
+Updates since v2.0
+------------------
+
+UI, Workflows & Features
+
+ * "git commit --date=<date>" option learned to read from more
+ timestamp formats, including "--date=now".
+
+ * "git grep" learned grep.fullname configuration variable to force
+ "--full-name" to be default. This may cause regressions on
+ scripted users that do not expect this new behaviour.
+
+ * "git merge" without argument, even when there is an upstream
+ defined for the current branch, refused to run until
+ merge.defaultToUpstream is set to true. Flip the default of that
+ configuration variable to true.
+
+ * "git mergetool" learned to drive the vimdiff3 backend.
+
+ * mergetool.prompt used to default to 'true', always asking "do you
+ really want to run the tool on this path?". Among the two
+ purposes this prompt serves, ignore the use case to confirm that
+ the user wants to view particular path with the named tool, and
+ redefine the meaning of the prompt only to confirm the choice of
+ the tool made by the autodetection (for those who configured the
+ tool explicitly, the prompt shown for the latter purpose is
+ simply annoying).
+
+ Strictly speaking, this is a backward incompatible change and the
+ users need to explicitly set the variable to 'true' if they want
+ to resurrect the now-ignored use case.
+
+ * "git svn" learned to cope with malformed timestamps with only one
+ digit in the hour part, e.g. 2014-01-07T5:01:02.048176Z, emitted
+ by some broken subversion server implementations.
+
+
+Performance, Internal Implementation, etc.
+
+ * "git diff" that compares 3-or-more trees (e.g. parents and the
+ result of a merge) have been optimized.
+
+ * The API to update/delete references are being converted to handle
+ updates to multiple references in a transactional way. As an
+ example, "update-ref --stdin [-z]" has been updated to use this
+ API.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.0
+----------------
+
+Unless otherwise noted, all the fixes since v2.0 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "--ignore-space-change" option of "git apply" ignored the spaces
+ at the beginning of line too aggressively, which is inconsistent
+ with the option of the same name "diff" and "git diff" have.
+ (merge 14d3bb4 jc/apply-ignore-whitespace later to maint).
+
+ * "git blame" miscounted number of columns needed to show localized
+ timestamps, resulting in jaggy left-side-edge of the source code
+ lines in its output.
+ (merge dd75553 jx/blame-align-relative-time later to maint).
+
+ * We used to disable threaded "git index-pack" on platforms without
+ thread-safe pread(); use a different workaround for such
+ platforms to allow threaded "git index-pack".
+ (merge 3953949 nd/index-pack-one-fd-per-thread later to maint).
+
+ * "git rerere forget" did not work well when merge.conflictstyle
+ was set to a non-default value.
+ (merge de3d8bb fc/rerere-conflict-style later to maint).
+
+ * "git status", even though it is a read-only operation, tries to
+ update the index with refreshed lstat(2) info to optimize future
+ accesses to the working tree opportunistically, but this could
+ race with a "read-write" operation that modify the index while it
+ is running. Detect such a race and avoid overwriting the index.
+ (merge 426ddee ym/fix-opportunistic-index-update-race later to maint).

+Notes
+-----
+
+git-filter-branch allows you to make complex shell-scripted rewrites
+of your Git history, but you probably don't need this flexibility if
+you're simply _removing unwanted data_ like large files or passwords.
+For those operations you may want to consider
+http://rtyley.github.io/bfg-repo-cleaner/[The BFG Repo-Cleaner],
+a JVM-based alternative to git-filter-branch, typically at least
+10-50x faster for those use-cases, and with quite different
+characteristics:
+
+* Any particular version of a file is cleaned exactly _once_. The BFG,
+ unlike git-filter-branch, does not give you the opportunity to
+ handle a file differently based on where or when it was committed
+ within your history. This constraint gives the core performance
+ benefit of The BFG, and is well-suited to the task of cleansing bad
+ data - you don't care _where_ the bad data is, you just want it
+ _gone_.
+
+* By default The BFG takes full advantage of multi-core machines,
+ cleansing commit file-trees in parallel. git-filter-branch cleans
+ commits sequentially (ie in a single-threaded manner), though it
+ _is_ possible to write filters that include their own parallellism,
+ in the scripts executed against each commit.
+
+* The http://rtyley.github.io/bfg-repo-cleaner/#examples[command options]
+ are much more restrictive than git-filter branch, and dedicated just
+ to the tasks of removing unwanted data- e.g:
+ `--strip-blobs-bigger-than 1M`.

-EXAMPLE
--------
-
-Suppose you run 'git tag -f' and mistype the tag to overwrite.
-The ref to your tag is overwritten, but until you run 'git

DESCRIPTION
-----------
-Summarizes the changes between two commits to the standard output, and includes
-the given URL in the generated summary.
+Generate a request asking your upstream project to pull changes into
+their tree. The request, printed to the standard output, summarizes
+the changes and indicates from where they can be pulled.
+
+The upstream project is expected to have the commit named by
+`<start>` and the output asks it to integrate the changes you made
+since that commit, up to the commit named by `<end>`, by visiting
+the repository named by `<url>`.
+
OPTIONS
-------
-p::
- Show patch text
+ Include patch text in the output.
<start>::
- Commit to start at.
+ Commit to start at. This names a commit that is already in
+ the upstream history.
<url>::

+ The repository URL to be pulled from.
<end>::
- Commit to end at; defaults to HEAD.
+ Commit to end at (defaults to HEAD). This names the commit
+ at the tip of the history you are asking to be pulled.
++
+When the repository named by `<url>` has the commit at a tip of a
+ref that is different from the ref you have locally, you can use the
+`<local>:<remote>` syntax, to have its local name, a colon `:`, and
+its remote name.
+
+
+EXAMPLE
+-------
+
+Imagine that you built your work on your `master` branch on top of
+the `v1.0` release, and want it to be integrated to the project.
+First you push that change to your public repository for others to
+see:
+
+ git push https://git.ko.xz/project master
+
+Then, you run this command:
+
+ git request-pull v1.0 https://git.ko.xz/project master
+
+which will produce a request to the upstream, summarizing the
+changes between the `v1.0` release and your `master`, to pull it
+from your public repository.
+
+If you pushed your change to a branch whose name is different from
+the one you have locally, e.g.
+
+ git push https://git.ko.xz/project master:for-linus
+
+then you can ask that to be pulled with

-===============
-
-NAME
-----
-git-tar-tree - Create a tar archive of the files in the named tree object
-
-
-SYNOPSIS
---------
-[verse]
-'git tar-tree' [--remote=<repo>] <tree-ish> [ <base> ]
-
-DESCRIPTION
------------
-THIS COMMAND IS DEPRECATED. Use 'git archive' with `--format=tar`
-option instead (and move the <base> argument to `--prefix=base/`).
-
-Creates a tar archive containing the tree structure for the named tree.
-When <base> is specified it is added as a leading path to the files in the
-generated tar archive.
-
-'git tar-tree' behaves differently when given a tree ID versus when given
-a commit ID or tag ID. In the first case the current time is used as
-modification time of each file in the archive. In the latter case the
-commit time as recorded in the referenced commit object is used instead.
-Additionally the commit ID is stored in a global extended pax header.
-It can be extracted using 'git get-tar-commit-id'.
-
-OPTIONS
--------
-
-<tree-ish>::
- The tree or commit to produce tar archive for. If it is
- the object name of a commit object.
-
-<base>::
- Leading path to the files in the resulting tar archive.
-
---remote=<repo>::
- Instead of making a tar archive from local repository,
- retrieve a tar archive from a remote repository.
-
-CONFIGURATION
--------------
-
-tar.umask::
- This variable can be used to restrict the permission bits of
- tar archive entries. The default is 0002, which turns off the
- world write bit. The special value "user" indicates that the
- archiving user's umask will be used instead. See umask(2) for
- details.
-
-EXAMPLES
---------
-`git tar-tree HEAD junk | (cd /var/tmp/ && tar xf -)`::
-
- Create a tar archive that contains the contents of the
- latest commit on the current branch, and extracts it in
- `/var/tmp/junk` directory.
-
-`git tar-tree v1.4.0 git-1.4.0 | gzip >git-1.4.0.tar.gz`::
-
- Create a tarball for v1.4.0 release.
-
-`git tar-tree v1.4.0^{tree} git-1.4.0 | gzip >git-1.4.0.tar.gz`::
-
- Create a tarball for v1.4.0 release, but without a
- global extended pax header.
-
-`git tar-tree --remote=example.com:git.git v1.4.0 >git-1.4.0.tar`::
-
- Get a tarball v1.4.0 from example.com.
-
-`git tar-tree HEAD:Documentation/ git-docs > git-1.4.0-docs.tar`::
-
- Put everything in the current head's Documentation/ directory
- into 'git-1.4.0-docs.tar', with the prefix 'git-docs/'.

+SECURITY
+--------
+
+In order to protect the privacy of objects that have been removed from
+history but may not yet have been pruned, `git-upload-archive` avoids
+serving archives for commits and trees that are not reachable from the
+repository's refs. However, because calculating object reachability is
+computationally expensive, `git-upload-archive` implements a stricter
+but easier-to-check set of rules:
+
+ 1. Clients may request a commit or tree that is pointed to directly by
+ a ref. E.g., `git archive --remote=origin v1.0`.
+
+ 2. Clients may request a sub-tree within a commit or tree using the
+ `ref:path` syntax. E.g., `git archive --remote=origin v1.0:Documentation`.
+
+ 3. Clients may _not_ use other sha1 expressions, even if the end
+ result is reachable. E.g., neither a relative commit like `master^`
+ nor a literal sha1 like `abcd1234` is allowed, even if the result
+ is reachable from the refs.
+
+Note that rule 3 disallows many cases that do not have any privacy
+implications. These rules are subject to change in future versions of
+git, and the server accessed by `git archive --remote` may or may not
+follow these exact rules.
+
+If the config option `uploadArchive.allowUnreachable` is true, these
+rules are ignored, and clients may use arbitrary sha1 expressions.
+This is useful if you do not care about the privacy of unreachable
+objects, or if your object database is already publicly available for
+access via non-smart-http.

+hashmap API
+===========
+
+The hashmap API is a generic implementation of hash-based key-value mappings.
+
+Data Structures
+---------------
+
+`struct hashmap`::
+
+ The hash table structure.
++
+The `size` member keeps track of the total number of entries. The `cmpfn`
+member is a function used to compare two entries for equality. The `table` and
+`tablesize` members store the hash table and its size, respectively.
+
+`struct hashmap_entry`::
+
+ An opaque structure representing an entry in the hash table, which must
+ be used as first member of user data structures. Ideally it should be
+ followed by an int-sized member to prevent unused memory on 64-bit
+ systems due to alignment.
++
+The `hash` member is the entry's hash code and the `next` member points to the
+next entry in case of collisions (i.e. if multiple entries map to the same
+bucket).
+
+`struct hashmap_iter`::
+
+ An iterator structure, to be used with hashmap_iter_* functions.
+
+Types
+-----
+
+`int (*hashmap_cmp_fn)(const void *entry, const void *entry_or_key, const void *keydata)`::
+
+ User-supplied function to test two hashmap entries for equality. Shall
+ return 0 if the entries are equal.
++
+This function is always called with non-NULL `entry` / `entry_or_key`
+parameters that have the same hash code. When looking up an entry, the `key`
+and `keydata` parameters to hashmap_get and hashmap_remove are always passed
+as second and third argument, respectively. Otherwise, `keydata` is NULL.
+
+Functions
+---------
+
+`unsigned int strhash(const char *buf)`::
+`unsigned int strihash(const char *buf)`::
+`unsigned int memhash(const void *buf, size_t len)`::
+`unsigned int memihash(const void *buf, size_t len)`::
+
+ Ready-to-use hash functions for strings, using the FNV-1 algorithm (see
+ http://www.isthe.com/chongo/tech/comp/fnv).
++
+`strhash` and `strihash` take 0-terminated strings, while `memhash` and
+`memihash` operate on arbitrary-length memory.
++
+`strihash` and `memihash` are case insensitive versions.
+
+`void hashmap_init(struct hashmap *map, hashmap_cmp_fn equals_function, size_t initial_size)`::
+
+ Initializes a hashmap structure.
++
+`map` is the hashmap to initialize.
++
+The `equals_function` can be specified to compare two entries for equality.
+If NULL, entries are considered equal if their hash codes are equal.
++
+If the total number of entries is known in advance, the `initial_size`
+parameter may be used to preallocate a sufficiently large table and thus
+prevent expensive resizing. If 0, the table is dynamically resized.
+
+`void hashmap_free(struct hashmap *map, int free_entries)`::
+
+ Frees a hashmap structure and allocated memory.
++
+`map` is the hashmap to free.
++
+If `free_entries` is true, each hashmap_entry in the map is freed as well
+(using stdlib's free()).
+
+`void hashmap_entry_init(void *entry, unsigned int hash)`::
+
+ Initializes a hashmap_entry structure.
++
+`entry` points to the entry to initialize.
++
+`hash` is the hash code of the entry.
+
+`void *hashmap_get(const struct hashmap *map, const void *key, const void *keydata)`::
+
+ Returns the hashmap entry for the specified key, or NULL if not found.
++
+`map` is the hashmap structure.
++
+`key` is a hashmap_entry structure (or user data structure that starts with
+hashmap_entry) that has at least been initialized with the proper hash code
+(via `hashmap_entry_init`).
++
+If an entry with matching hash code is found, `key` and `keydata` are passed
+to `hashmap_cmp_fn` to decide whether the entry matches the key.
+
+`void *hashmap_get_next(const struct hashmap *map, const void *entry)`::
+
+ Returns the next equal hashmap entry, or NULL if not found. This can be
+ used to iterate over duplicate entries (see `hashmap_add`).
++
+`map` is the hashmap structure.
++
+`entry` is the hashmap_entry to start the search from, obtained via a previous
+call to `hashmap_get` or `hashmap_get_next`.
+
+`void hashmap_add(struct hashmap *map, void *entry)`::
+
+ Adds a hashmap entry. This allows to add duplicate entries (i.e.
+ separate values with the same key according to hashmap_cmp_fn).
++
+`map` is the hashmap structure.
++
+`entry` is the entry to add.
+
+`void *hashmap_put(struct hashmap *map, void *entry)`::
+
+ Adds or replaces a hashmap entry. If the hashmap contains duplicate
+ entries equal to the specified entry, only one of them will be replaced.
++
+`map` is the hashmap structure.
++
+`entry` is the entry to add or replace.
++
+Returns the replaced entry, or NULL if not found (i.e. the entry was added).
+
+`void *hashmap_remove(struct hashmap *map, const void *key, const void *keydata)`::
+
+ Removes a hashmap entry matching the specified key. If the hashmap
+ contains duplicate entries equal to the specified key, only one of
+ them will be removed.
++
+`map` is the hashmap structure.
++
+`key` is a hashmap_entry structure (or user data structure that starts with
+hashmap_entry) that has at least been initialized with the proper hash code
+(via `hashmap_entry_init`).
++
+If an entry with matching hash code is found, `key` and `keydata` are
+passed to `hashmap_cmp_fn` to decide whether the entry matches the key.
++
+Returns the removed entry, or NULL if not found.
+
+`void hashmap_iter_init(struct hashmap *map, struct hashmap_iter *iter)`::
+`void *hashmap_iter_next(struct hashmap_iter *iter)`::
+`void *hashmap_iter_first(struct hashmap *map, struct hashmap_iter *iter)`::
+
+ Used to iterate over all entries of a hashmap.
++
+`hashmap_iter_init` initializes a `hashmap_iter` structure.
++
+`hashmap_iter_next` returns the next hashmap_entry, or NULL if there are no
+more entries.
++
+`hashmap_iter_first` is a combination of both (i.e. initializes the iterator
+and returns the first entry, if any).
+
+Usage example
+-------------
+
+Here's a simple usage example that maps long keys to double values.
+------------
+struct hashmap map;
+
+struct long2double {
+ struct hashmap_entry ent; /* must be the first member! */
+ long key;
+ double value;
+};
+
+static int long2double_cmp(const struct long2double *e1, const struct long2double *e2, const void *unused)
+{
+ return !(e1->key == e2->key);
+}
+
+void long2double_init(void)
+{
+ hashmap_init(&map, (hashmap_cmp_fn) long2double_cmp, 0);
+}
+
+void long2double_free(void)
+{
+ hashmap_free(&map, 1);
+}
+
+static struct long2double *find_entry(long key)
+{
+ struct long2double k;
+ hashmap_entry_init(&k, memhash(&key, sizeof(long)));
+ k.key = key;
+ return hashmap_get(&map, &k, NULL);
+}
+
+double get_value(long key)
+{
+ struct long2double *e = find_entry(key);
+ return e ? e->value : 0;

+
+Using variable-sized keys
+-------------------------
+
+The `hashmap_entry_get` and `hashmap_entry_remove` functions expect an ordinary
+`hashmap_entry` structure as key to find the correct entry. If the key data is
+variable-sized (e.g. a FLEX_ARRAY string) or quite large, it is undesirable
+to create a full-fledged entry structure on the heap and copy all the key data
+into the structure.
+
+In this case, the `keydata` parameter can be used to pass
+variable-sized key data directly to the comparison function, and the `key`
+parameter can be a stripped-down, fixed size entry structure allocated on the
+stack.
+
+See test-hashmap.c for an example using arbitrary-length strings as keys.

+GIT bitmap v1 format
+====================
+
+ - A header appears at the beginning:
+
+ 4-byte signature: {'B', 'I', 'T', 'M'}
+
+ 2-byte version number (network byte order)
+ The current implementation only supports version 1
+ of the bitmap index (the same one as JGit).
+
+ 2-byte flags (network byte order)
+
+ The following flags are supported:
+
+ - BITMAP_OPT_FULL_DAG (0x1) REQUIRED
+ This flag must always be present. It implies that the bitmap
+ index has been generated for a packfile with full closure
+ (i.e. where every single object in the packfile can find
+ its parent links inside the same packfile). This is a
+ requirement for the bitmap index format, also present in JGit,
+ that greatly reduces the complexity of the implementation.
+
+ - BITMAP_OPT_HASH_CACHE (0x4)
+ If present, the end of the bitmap file contains
+ `N` 32-bit name-hash values, one per object in the
+ pack. The format and meaning of the name-hash is
+ described below.
+
+ 4-byte entry count (network byte order)
+
+ The total count of entries (bitmapped commits) in this bitmap index.
+
+ 20-byte checksum
+
+ The SHA1 checksum of the pack this bitmap index belongs to.
+
+ - 4 EWAH bitmaps that act as type indexes
+
+ Type indexes are serialized after the hash cache in the shape
+ of four EWAH bitmaps stored consecutively (see Appendix A for
+ the serialization format of an EWAH bitmap).
+
+ There is a bitmap for each Git object type, stored in the following
+ order:
+
+ - Commits
+ - Trees
+ - Blobs
+ - Tags
+
+ In each bitmap, the `n`th bit is set to true if the `n`th object
+ in the packfile is of that type.
+
+ The obvious consequence is that the OR of all 4 bitmaps will result
+ in a full set (all bits set), and the AND of all 4 bitmaps will
+ result in an empty bitmap (no bits set).
+
+ - N entries with compressed bitmaps, one for each indexed commit
+
+ Where `N` is the total amount of entries in this bitmap index.
+ Each entry contains the following:
+
+ - 4-byte object position (network byte order)
+ The position **in the index for the packfile** where the
+ bitmap for this commit is found.
+
+ - 1-byte XOR-offset
+ The xor offset used to compress this bitmap. For an entry
+ in position `x`, a XOR offset of `y` means that the actual
+ bitmap representing this commit is composed by XORing the
+ bitmap for this entry with the bitmap in entry `x-y` (i.e.
+ the bitmap `y` entries before this one).
+
+ Note that this compression can be recursive. In order to
+ XOR this entry with a previous one, the previous entry needs
+ to be decompressed first, and so on.
+
+ The hard-limit for this offset is 160 (an entry can only be
+ xor'ed against one of the 160 entries preceding it). This
+ number is always positive, and hence entries are always xor'ed
+ with **previous** bitmaps, not bitmaps that will come afterwards
+ in the index.
+
+ - 1-byte flags for this bitmap
+ At the moment the only available flag is `0x1`, which hints
+ that this bitmap can be re-used when rebuilding bitmap indexes
+ for the repository.
+
+ - The compressed bitmap itself, see Appendix A.
+
+== Appendix A: Serialization format for an EWAH bitmap
+
+Ewah bitmaps are serialized in the same protocol as the JAVAEWAH
+library, making them backwards compatible with the JGit
+implementation:
+
+ - 4-byte number of bits of the resulting UNCOMPRESSED bitmap
+
+ - 4-byte number of words of the COMPRESSED bitmap, when stored
+
+ - N x 8-byte words, as specified by the previous field
+
+ This is the actual content of the compressed bitmap.
+
+ - 4-byte position of the current RLW for the compressed
+ bitmap
+
+All words are stored in network byte order for their corresponding
+sizes.
+
+The compressed bitmap is stored in a form of run-length encoding, as
+follows. It consists of a concatenation of an arbitrary number of
+chunks. Each chunk consists of one or more 64-bit words
+
+ H L_1 L_2 L_3 .... L_M
+
+H is called RLW (run length word). It consists of (from lower to higher
+order bits):
+
+ - 1 bit: the repeated bit B
+
+ - 32 bits: repetition count K (unsigned)
+
+ - 31 bits: literal word count M (unsigned)
+
+The bitstream represented by the above chunk is then:
+
+ - K repetitions of B
+
+ - The bits stored in `L_1` through `L_M`. Within a word, bits at
+ lower order come earlier in the stream than those at higher
+ order.
+
+The next word after `L_M` (if any) must again be a RLW, for the next
+chunk. For efficient appending to the bitstream, the EWAH stores a
+pointer to the last RLW in the stream.
+
+
+== Appendix B: Optional Bitmap Sections
+
+These sections may or may not be present in the `.bitmap` file; their
+presence is indicated by the header flags section described above.
+
+Name-hash cache
+---------------
+
+If the BITMAP_OPT_HASH_CACHE flag is set, the end of the bitmap contains
+a cache of 32-bit values, one per object in the pack. The value at
+position `i` is the hash of the pathname at which the `i`th object
+(counting in index order) in the pack can be found. This can be fed
+into the delta heuristics to compare objects with similar pathnames.
+
+The hash algorithm used is:
+
+ hash = 0;
+ while ((c = *name++))
+ if (!isspace(c))
+ hash = (hash >> 2) + (c << 24);
+
+Note that this hashing scheme is tied to the BITMAP_OPT_HASH_CACHE flag.
+If implementations want to choose a different hashing scheme, they are
+free to do so, but MUST allocate a new header flag (because comparing
+hashes made under two different schemes would be pointless).

+This capability should only be used with the smart HTTP protocol. If

+thus slightly reduces latency.
+
thin-pack
---------
-This capability means that the server can send a 'thin' pack, a pack
-which does not contain base objects; if those base objects are available
-on client side. Client requests 'thin-pack' capability when it
-understands how to "thicken" it by adding required delta bases making
-it self-contained.
-
-Client MUST NOT request 'thin-pack' capability if it cannot turn a thin
-pack into a self-contained pack.
+A thin pack is one with deltas which reference base objects not
+contained within the pack (but are known to exist at the receiving
+end). This can reduce the network traffic significantly, but it
+requires the receiving end to know how to "thicken" these packs by
+adding the missing bases to the pack.
+
+The upload-pack server advertises 'thin-pack' when it can generate
+and send a thin pack. A client requests the 'thin-pack' capability
+when it understands how to "thicken" it, notifying the server that
+it can receive such a pack. A client MUST NOT request the
+'thin-pack' capability if it cannot turn a thin pack into a
+self-contained pack.
+
+Receive-pack, on the other hand, is assumed by default to be able to
+handle thin packs, but can ask the client not to use the feature by
+advertising the 'no-thin' capability. A client MUST NOT send a thin
+pack if the server advertises the 'no-thin' capability.
+
+The reasons for this asymmetry are historical. The receive-pack
+program did not exist until after the invention of thin packs, so
+historically the reference implementation of receive-pack always
+understood thin packs. Adding 'no-thin' later allowed receive-pack
+to disable the feature in a backwards-compatible manner.
