+Git v2.2 Release Notes
+======================
+
+Updates since v2.1
+------------------
+
+Ports
+
+ * Building on older MacOS X systems automatically sets
+ the necessary NO_APPLE_COMMON_CRYPTO build-time option.
+
+
+UI, Workflows & Features
+
+ * "git config --edit --global" starts from a skeletal per-user
+ configuration file contents, instead of a total blank, when the
+ user does not already have any. This immediately reduces the
+ need for a later "Have you forgotten setting core.user?" and we
+ can add more to the template as we gain more experience.
+
+ * "git stash list -p" used to be almost always a no-op because each
+ stash entry is represented as a merge commit. It learned to show
+ the difference between the base commit version and the working tree
+ version, which is in line with what "git show" gives.
+
+ * Sometimes users want to report a bug they experience on their
+ repository, but they are not at liberty to share the contents of
+ the repository. "fast-export" was taught an "--anonymize" option
+ to replace blob contents, names of people and paths and log
+ messages with bland and simple strings to help them.
+
+ * "log --date=iso" uses a slight variant of ISO 8601 format that is
+ made more human readable. A new "--date=iso-strict" option gives
+ datetime output that is more strictly conformant.
+
+ * A broken reimplementation of Git could write an invalid index that
+ records both stage #0 and higher stage entries for the same path.
+ We now notice and reject such an index, as there is no sensible
+ fallback (we do not know if the broken tool wanted to resolve and
+ forgot to remove higher stage entries, or if it wanted to unresolve
+ and forgot to remove the stage#0 entry).
+
+ * The "pre-receive" and "post-receive" hooks are no longer required
+ to consume their input fully (not following this requirement used
+ to result in intermittent errors in "git push").
+
+ * The pretty-format specifier "%d", which expanded to " (tagname)"
+ for a tagged commit, gained a cousin "%D" that just gives the
+ "tagname" without frills.
+
+Performance, Internal Implementation, etc.
+
+ * The API to manipulate the "refs" is currently undergoing a revamp
+ to make it more transactional, with the eventual goal to allow
+ all-or-none atomic updates and migrating the storage to something
+ other than the traditional filesystem based one (e.g. databases).
+
+ * We no longer attempt to keep track of individual dependencies to
+ the header files in the build procedure, relying on automated
+ dependency generation support from modern compilers.
+
+ * In tests, we have been using NOT_{MINGW,CYGWIN} test prerequisites
+ long before negated prerequisites e.g. !MINGW were invented.
+ The former has been converted to the latter to avoid confusion.
+
+ * Looking up remotes configuration in a repository with very many
+ remotes defined has been optimized.
+
+ * There are cases where you lock and open to write a file, close it
+ to show the updated contents to external processes, and then have
+ to update the file again while still holding the lock, but the
+ lockfile API lacked support for such an access pattern.
+
+ * The API to allocate the structure to keep track of commit
+ decoration has been updated to make it less cumbersome to use.
+
+ * An in-core caching layer to let us avoid reading the same
+ configuration files number of times has been added. A few commands
+ have been converted to use this subsystem.
+
+ * Various code paths have been cleaned up and simplified by using
+ "strbuf", "starts_with()", and "skip_prefix()" APIs more.
+
+ * A few codepaths that died when large blobs that would not fit in
+ core are involved in their operation have been taught to punt
+ instead, by e.g. marking too large a blob as not to be diffed.
+
+ * A few more code paths in "commit" and "checkout" have been taught
+ to repopulate the cache-tree in the index, to help speed up later
+ "write-tree" (used in "commit") and "diff-index --cached" (used in
+ "status").
+
+ * A common programming mistake to assign the same short option name
+ to two separate options is detected by parse_options() API to help
+ developers.
+
+ * The code path to write out the packed-refs file has been optimized,
+ which especially matters in a repository with a large number of
+ refs.
+
+ * The check to see if a ref $F can be created by making sure no
+ existing ref has $F/ as its prefix has been optimized, which
+ especially matters in a repository with a large number of existing
+ refs.
+
+ * "git fsck" was taught to check contents of tag objects a bit more.
+
+ * "git hash-object" was taught a "--literally" option to help
+ debugging.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.1
+----------------
+
+Unless otherwise noted, all the fixes since v2.1 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git log --pretty/format=" with an empty format string did not
+ mean the more obvious "No output whatsoever" but "Use default
+ format", which was counterintuitive.
+
+ * Implementations of "tar" that do not understand an extended pax
+ header would extract the contents of it in a regular file; make
+ sure the permission bits of this file follows the same tar.umask
+ configuration setting.
+
+ * "git -c section.var command" and "git -c section.var= command"
+ should pass the configuration differently (the former should be a
+ boolean true, the latter should be an empty string).
+
+ * Applying a patch not generated by Git in a subdirectory used to
+ check the whitespace breakage using the attributes for incorrect
+ paths. Also whitespace checks were performed even for paths
+ excluded via "git apply --exclude=<path>" mechanism.
+
+ * "git bundle create" with date-range specification were meant to
+ exclude tags outside the range, but it didn't.
+
+ * "git add x" where x that used to be a directory has become a
+ symbolic link to a directory misbehaved.
+
+ * The prompt script checked $GIT_DIR/ref/stash file to see if there
+ is a stash, which was a no-no.
+
+ * Pack-protocol documentation had a minor typo.
+
+ * "git checkout -m" did not switch to another branch while carrying
+ the local changes forward when a path was deleted from the index.
+
+ * With sufficiently long refnames, "git fast-import" could have
+ overflown an on-stack buffer.
+
+ * After "pack-refs --prune" packed refs at the top-level, it failed
+ to prune them.
+
+ * Progress output from "git gc --auto" was visible in "git fetch -q".
+
+ * We used to pass -1000 to poll(2), expecting it to also mean "no
+ timeout", which should be spelled as -1.
+
+ * "git rebase" documentation was unclear that it is required to
+ specify on what <upstream> the rebase is to be done when telling it
+ to first check out <branch>.
+ (merge 95c6826 so/rebase-doc later to maint).
+
+ * "git push" over HTTP transport had an artificial limit on number of
+ refs that can be pushed imposed by the command line length.
+ (merge 26be19b jk/send-pack-many-refspecs later to maint).
+
+ * When receiving an invalid pack stream that records the same object
+ twice, multiple threads got confused due to a race.
+ (merge ab791dd jk/index-pack-threading-races later to maint).
+
+ * An attempt to remove the entire tree in the "git fast-import" input
+ stream caused it to misbehave.
+ (merge 2668d69 mb/fast-import-delete-root later to maint).
+
+ * Reachability check (used in "git prune" and friends) did not add a
+ detached HEAD as a starting point to traverse objects still in use.
+ (merge c40fdd0 mk/reachable-protect-detached-head later to maint).
+
+ * "git config --add section.var val" used to lose existing
+ section.var whose value was an empty string.
+ (merge c1063be ta/config-add-to-empty-or-true-fix later to maint).
+
+ * "git fsck" failed to report that it found corrupt objects via its
+ exit status in some cases.
+ (merge 30d1038 jk/fsck-exit-code-fix later to maint).
+
+ * Use of "--verbose" option used to break "git branch --merged".
+ (merge 12994dd jk/maint-branch-verbose-merged later to maint).
+
+ * Some MUAs mangled a line in a message that begins with "From " to
+ ">From " when writing to a mailbox file and feeding such an input
+ to "git am" used to lose such a line.
+ (merge 85de86a jk/mbox-from-line later to maint).
+
+ * "rev-parse --verify --quiet $name" is meant to quietly exit with a
+ non-zero status when $name is not a valid object name, but still
+ gave error messages in some cases.
Files larger than this size are stored deflated, without
attempting delta compression. Storing large files without
delta compression avoids excessive memory usage, at the
- slight expense of increased disk usage.
+ slight expense of increased disk usage. Additionally files

in the commit (as opposed to just listing the files which are
different from the commit's first parent).
+--anonymize::
+ Anonymize the contents of the repository while still retaining
+ the shape of the history and stored tree. See the section on
+ `ANONYMIZING` below.
+
--refspec::
Apply the specified refspec to each ref exported. Multiple of them can
be specified.
'refs/heads/master'.
+ANONYMIZING
+-----------
+
+If the `--anonymize` option is given, git will attempt to remove all
+identifying information from the repository while still retaining enough
+of the original tree and history patterns to reproduce some bugs. The
+goal is that a git bug which is found on a private repository will
+persist in the anonymized repository, and the latter can be shared with
+git developers to help solve the bug.
+
+With this option, git will replace all refnames, paths, blob contents,
+commit and tag messages, names, and email addresses in the output with
+anonymized data. Two instances of the same string will be replaced
+equivalently (e.g., two commits with the same author will have the same
+anonymized author in the output, but bear no resemblance to the original
+author string). The relationship between commits, branches, and tags is
+retained, as well as the commit timestamps (but the commit messages and
+refnames bear no resemblance to the originals). The relative makeup of
+the tree is retained (e.g., if you have a root tree with 10 files and 3
+trees, so will the output), but their names and the contents of the
+files will be replaced.
+
+If you think you have found a git bug, you can start by exporting an
+anonymized stream of the whole repository:
+
+---------------------------------------------------
+$ git fast-export --anonymize --all >anon-stream
+---------------------------------------------------
+
+Then confirm that the bug persists in a repository created from that
+stream (many bugs will not, as they really do depend on the exact
+repository contents):
+
+---------------------------------------------------
+$ git init anon-repo
+$ cd anon-repo
+$ git fast-import <../anon-stream
+$ ... test your bug ...
+---------------------------------------------------
+
+If the anonymized repository shows the bug, it may be worth sharing
+`anon-stream` along with a regular bug report. Note that the anonymized
+stream compresses very well, so gzipping it is encouraged. If you want
+to examine the stream to see that it does not contain any private data,
+you can peruse it directly before sending. You may also want to try:
+
+---------------------------------------------------
+$ perl -pe 's/\d+/X/g' <anon-stream | sort -u | less
+---------------------------------------------------
+
+which shows all of the unique lines (with numbers converted to "X", to
+collapse "User 0", "User 1", etc into "User X"). This produces a much
+smaller output, and it is usually easy to quickly confirm that there is
+no private data in the stream.
+
+
Limitations

+Only print error and warning messages; all other output will be suppressed.
--bare::
--separate-git-dir=<git dir>::
-Instead of initializing the repository where it is supposed to be,
-place a filesytem-agnostic Git symbolic link there, pointing to the
-specified path, and initialize a Git repository at the path. The
-result is Git repository can be separated from working tree. If this
-is reinitialization, the repository will be moved to the specified
-path.
+Instead of initializing the repository as a directory to either `$GIT_DIR` or
+`./.git/`, create a text file there containing the path to the actual
+repository. This file acts as filesystem-agnostic Git symbolic link to the
+repository.
++
+If this is reinitialization, the repository will be moved to the specified path.
--shared[=(false|true|umask|group|all|world|everybody|0xxx)]::
set so that files and directories under `$GIT_DIR` are created with the
requested permissions. When not specified, Git will use permissions reported
by umask(2).
-
++
The option can have the following values, defaulting to 'group' if no value
is given:
++
+--
+'umask' (or 'false')::
- - 'umask' (or 'false'): Use permissions reported by umask(2). The default,
- when `--shared` is not specified.
+Use permissions reported by umask(2). The default, when `--shared` is not
+specified.
- - 'group' (or 'true'): Make the repository group-writable, (and g+sx, since
- the git group may be not the primary group of all users).
- This is used to loosen the permissions of an otherwise safe umask(2) value.
- Note that the umask still applies to the other permission bits (e.g. if
- umask is '0022', using 'group' will not remove read privileges from other
- (non-group) users). See '0xxx' for how to exactly specify the repository
- permissions.
+'group' (or 'true')::
- - 'all' (or 'world' or 'everybody'): Same as 'group', but make the repository
- readable by all users.
+Make the repository group-writable, (and g+sx, since the git group may be not
+the primary group of all users). This is used to loosen the permissions of an
+otherwise safe umask(2) value. Note that the umask still applies to the other
+permission bits (e.g. if umask is '0022', using 'group' will not remove read
+privileges from other (non-group) users). See '0xxx' for how to exactly specify
+the repository permissions.
- - '0xxx': '0xxx' is an octal number and each file will have mode '0xxx'.
- '0xxx' will override users' umask(2) value (and not only loosen permissions
- as 'group' and 'all' does). '0640' will create a repository which is
- group-readable, but not group-writable or accessible to others. '0660' will
- create a repo that is readable and writable to the current user and group,
- but inaccessible to others.
+'all' (or 'world' or 'everybody')::
-By default, the configuration flag receive.denyNonFastForwards is enabled
+Same as 'group', but make the repository readable by all users.
+
+'0xxx'::
+
+'0xxx' is an octal number and each file will have mode '0xxx'. '0xxx' will
+override users' umask(2) value (and not only loosen permissions as 'group' and
+'all' does). '0640' will create a repository which is group-readable, but not
+group-writable or accessible to others. '0660' will create a repo that is
+readable and writable to the current user and group, but inaccessible to others.
+--
+
+By default, the configuration flag `receive.denyNonFastForwards` is enabled
in shared repositories, so that you cannot force a non fast-forwarding push
into it.
-If you name a (possibly non-existent) directory at the end of the command
-line, the command is run inside the directory (possibly after creating it).
+If you provide a 'directory', the command is run inside it. If this directory
+does not exist, it will be created.

`git_config_from_file`. This takes the same callback and data parameters

+Querying For Specific Variables
+-------------------------------
+
+For programs wanting to query for specific variables in a non-callback
+manner, the config API provides two functions `git_config_get_value`
+and `git_config_get_value_multi`. They both read values from an internal
+cache generated previously from reading the config files.
+
+`int git_config_get_value(const char *key, const char **value)`::
+
+ Finds the highest-priority value for the configuration variable `key`,
+ stores the pointer to it in `value` and returns 0. When the
+ configuration variable `key` is not found, returns 1 without touching
+ `value`. The caller should not free or modify `value`, as it is owned
+ by the cache.
+
+`const struct string_list *git_config_get_value_multi(const char *key)`::
+
+ Finds and returns the value list, sorted in order of increasing priority
+ for the configuration variable `key`. When the configuration variable
+ `key` is not found, returns NULL. The caller should not free or modify
+ the returned pointer, as it is owned by the cache.
+
+`void git_config_clear(void)`::
+
+ Resets and invalidates the config cache.
+
+The config API also provides type specific API functions which do conversion
+as well as retrieval for the queried variable, including:
+
+`int git_config_get_int(const char *key, int *dest)`::
+
+ Finds and parses the value to an integer for the configuration variable
+ `key`. Dies on error; otherwise, stores the value of the parsed integer in
+ `dest` and returns 0. When the configuration variable `key` is not found,
+ returns 1 without touching `dest`.
+
+`int git_config_get_ulong(const char *key, unsigned long *dest)`::
+
+ Similar to `git_config_get_int` but for unsigned longs.
+
+`int git_config_get_bool(const char *key, int *dest)`::
+
+ Finds and parses the value into a boolean value, for the configuration
+ variable `key` respecting keywords like "true" and "false". Integer
+ values are converted into true/false values (when they are non-zero or
+ zero, respectively). Other values cause a die(). If parsing is successful,
+ stores the value of the parsed result in `dest` and returns 0. When the
+ configuration variable `key` is not found, returns 1 without touching
+ `dest`.
+
+`int git_config_get_bool_or_int(const char *key, int *is_bool, int *dest)`::
+
+ Similar to `git_config_get_bool`, except that integers are copied as-is,
+ and `is_bool` flag is unset.
+
+`int git_config_get_maybe_bool(const char *key, int *dest)`::
+
+ Similar to `git_config_get_bool`, except that it returns -1 on error
+ rather than dying.
+
+`int git_config_get_string_const(const char *key, const char **dest)`::
+
+ Allocates and copies the retrieved string into the `dest` parameter for
+ the configuration variable `key`; if NULL string is given, prints an
+ error message and returns -1. When the configuration variable `key` is
+ not found, returns 1 without touching `dest`.
+
+`int git_config_get_string(const char *key, char **dest)`::
+
+ Similar to `git_config_get_string_const`, except that retrieved value
+ copied into the `dest` parameter is a mutable string.
+
+`int git_config_get_pathname(const char *key, const char **dest)`::
+
+ Similar to `git_config_get_string`, but expands `~` or `~user` into
+ the user's home directory when found at the beginning of the path.
+
+`git_die_config(const char *key, const char *err, ...)`::
+
+ First prints the error message specified by the caller in `err` and then
+ dies printing the line number and the file name of the highest priority
+ value for the configuration variable `key`.
+
+`void git_die_config_linenr(const char *key, const char *filename, int linenr)`::
+
+ Helper function which formats the die error message according to the
+ parameters entered. Used by `git_die_config()`. It can be used by callers
+ handling `git_config_get_value_multi()` to print the correct error message
+ for the desired value.
+
+See test-config.c for usage examples.
+
Value Parsing Helpers
---------------------
`git_config` respects includes automatically. The lower-level
`git_config_from_file` does not.
+Custom Configsets
+-----------------
+
+A `config_set` can be used to construct an in-memory cache for
+config-like files that the caller specifies (i.e., files like `.gitmodules`,
+`~/.gitconfig` etc.). For example,
+
+---------------------------------------
+struct config_set gm_config;
+git_configset_init(&gm_config);
+int b;
+/* we add config files to the config_set */
+git_configset_add_file(&gm_config, ".gitmodules");
+git_configset_add_file(&gm_config, ".gitmodules_alt");
+
+if (!git_configset_get_bool(gm_config, "submodule.frotz.ignore", &b)) {
+ /* hack hack hack */
+}
+
+/* when we are done with the configset */
+git_configset_clear(&gm_config);
+----------------------------------------
+
+Configset API provides functions for the above mentioned work flow, including:
+
+`void git_configset_init(struct config_set *cs)`::
+
+ Initializes the config_set `cs`.
+
+`int git_configset_add_file(struct config_set *cs, const char *filename)`::
+
+ Parses the file and adds the variable-value pairs to the `config_set`,
+ dies if there is an error in parsing the file. Returns 0 on success, or
+ -1 if the file does not exist or is inaccessible. The user has to decide
+ if he wants to free the incomplete configset or continue using it when
+ the function returns -1.
+
+`int git_configset_get_value(struct config_set *cs, const char *key, const char **value)`::
+
+ Finds the highest-priority value for the configuration variable `key`
+ and config set `cs`, stores the pointer to it in `value` and returns 0.
+ When the configuration variable `key` is not found, returns 1 without
+ touching `value`. The caller should not free or modify `value`, as it
+ is owned by the cache.
+
+`const struct string_list *git_configset_get_value_multi(struct config_set *cs, const char *key)`::
+
+ Finds and returns the value list, sorted in order of increasing priority
+ for the configuration variable `key` and config set `cs`. When the
+ configuration variable `key` is not found, returns NULL. The caller
+ should not free or modify the returned pointer, as it is owned by the cache.
+
+`void git_configset_clear(struct config_set *cs)`::
+
+ Clears `config_set` structure, removes all saved variable-value pairs.
+
+In addition to above functions, the `config_set` API provides type specific
+functions in the vein of `git_config_get_int` and family but with an extra
+parameter, pointer to struct `config_set`.
+They all behave similarly to the `git_config_get*()` family described in
+"Querying For Specific Variables" above.
+
Writing Config Files
--------------------
Functions
---------
+`child_process_init`
+
+ Initialize a struct child_process variable.
+
`start_command`::
Start a sub-process. Takes a pointer to a `struct child_process`
The caller:
-1. allocates and clears (memset(&chld, 0, sizeof(chld));) a
- struct child_process variable;
+1. allocates and clears (using child_process_init() or
+ CHILD_PROCESS_INIT) a struct child_process variable;
2. initializes the members;
3. calls start_command();
4. processes the data;
Add a single character to the buffer.
+`strbuf_addchars`::
+
+ Add a character the specified number of times to the buffer.
+
`strbuf_insert`::
Insert data to the given position of the buffer. The remaining contents
use it unless you need the correct position in the file
descriptor.
+`strbuf_getcwd`::
+
+ Set the buffer to the path of the current working directory.
+
+`strbuf_add_absolute_path`
+
+ Add a path to a buffer, converting a relative path to an
+ absolute one in the process. Symbolic links are not
+ resolved.
+
`stripspace`::
Strip whitespace from a buffer. The second parameter controls if
#!/bin/sh

+ * A ref_transaction represents a collection of ref updates

+ * Calling sequence
+ * ----------------
+ * - Allocate and initialize a `struct ref_transaction` by calling
+ * `ref_transaction_begin()`.
+ *
+ * - List intended ref updates by calling functions like
+ * `ref_transaction_update()` and `ref_transaction_create()`.
+ *
+ * - Call `ref_transaction_commit()` to execute the transaction.
+ * If this succeeds, the ref updates will have taken place and
+ * the transaction cannot be rolled back.
+ *
+ * - At any time call `ref_transaction_free()` to discard the
+ * transaction and free associated resources. In particular,
+ * this rolls back the transaction if it has not been
+ * successfully committed.
+ *
+ * Error handling
+ * --------------
+ *
+ * On error, transaction functions append a message about what
+ * went wrong to the 'err' argument. The message mentions what
+ * ref was being updated (if any) when the error occurred so it
+ * can be passed to 'die' or 'error' as-is.
+ *
+ * The message is appended to err without first clearing err.
+ * err will not be '\n' terminated.
