+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.
+
+
+Updates since v1.9 series
+-------------------------
+
+UI, Workflows & Features
+
+ * "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" have been updated to help C++ source better.
+
+ * "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 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.
+
+ * transport-helper, fast-import and fast-export have been updated to
+ allow the ref mapping and ref deletion 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 an attempt to use an object that
+ is not a blob as an error.
+
+ * "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 of
+ course is rejected).
+
+ * 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", "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 "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.
+
+ * "git reset" learned "-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 form a
+ repository that uses it.
+
+ * The way "git log --cc" shows a combined diff against multiple
+ parents have 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 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).
+
+ * Codepaths 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 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 later 655ee9e mw/symlinks to maint.)
+
+ * "git diff --quiet -- pathspec1 pathspec2" sometimes did not return
+ 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 no-done
+ extension was used. The fetching side waited for the list of
+ shallow boundary commits after the sending end 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).

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>::
- URL to include in the summary.
+ 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
+
+ git request-pull v1.0 https://git.ko.xz/project master:for-linus

for the protocol is on the 'git archive' side, and the program pair
is meant to be used to get an archive from a remote repository.
+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.

-
- Release memory associated with the hash table.
-
-`insert_hash`::
-
- Insert a pointer into the hash table. If an entry with that hash

- Lookup an entry in the hash table. If an entry with that hash exists
- the entry's value is returned. Otherwise NULL is returned.
-
-`for_each_hash`::

+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.
+[source,c]
+------------
+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;
+}
+
+void set_value(long key, double value)
+{
+ struct long2double *e = find_entry(key);
+ if (!e) {
+ e = malloc(sizeof(struct long2double));
+ hashmap_entry_init(e, memhash(&key, sizeof(long)));
+ e->key = key;
+ hashmap_add(&map, e);
+ }
+ e->value = value;
+}
+------------
+
+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).

+How to write RIGHT test cases
+=============================
+
+Insert the word "ChangeMe" (exactly this form) at a distance of
+at least two lines from the line that must appear in the hunk header.
+
+The text that must appear in the hunk header must contain the word
+"right", but in all upper-case, like in the title above.
+
+To mark a test case that highlights a malfunction, insert the word
+BROKEN in all lower-case somewhere in the file.
+
+This text is a bit twisted and out of order, but it is itself a
+test case for the default hunk header pattern. Know what you are doing
+if you change it.
+
+BTW, this tests that the head line goes to the hunk header, not the line
+of equal signs.
