+GIT v1.5.4.3 Release Notes
+==========================
+
+Fixes since v1.5.4.2
+--------------------
+
+ * RPM spec used to pull in everything with 'git'. This has been
+ changed so that 'git' package contains just the core parts,
+ and we now supply 'git-all' metapackage to slurp in everything.
+ This should match end user's expectation better.
+
+ * When some refs failed to update, git-push reported "failure"
+ which was unclear if some other refs were updated or all of
+ them failed atomically (the answer is the former). Reworded
+ the message to clarify this.
+
+ * "git clone" from a repository whose HEAD was misconfigured
+ did not set up the remote properly. Now it tries to do
+ better.
+
+ * Updated git-push documentation to clarify what "matching"
+ means, in order to reduce user confusion.
+
+ * Updated git-add documentation to clarify "add -u" operates in
+ the current subdirectory you are in, just like other commands.
+
+ * git-gui updates to work on OSX and Windows better.
error (enabled by default).
* `indent-with-non-tab` treats a line that is indented with 8 or more
space characters as an error (not enabled by default).
+* `cr-at-eol` treats a carriage-return at the end of line as
+ part of the line terminator, i.e. with it, `trailing-space`
+ does not trigger if the character before such a carriage-return
+ is not a whitespace (not enabled by default).
alias.*::
Command aliases for the linkgit:git[1] command wrapper - e.g.
commit.template::
Specify a file to use as the template for new commit messages.
+color.ui::
+ When set to `always`, always use colors in all git commands which
+ are capable of colored output. When false (or `never`), never. When
+ set to `true` or `auto`, use colors only when the output is to the
+ terminal. When more specific variables of color.* are set, they always
+ take precedence over this setting. Defaults to false.
+
diff.autorefreshindex::
When using `git diff` to compare with work tree
files, do not consider stat-only change as changed.
warning. This is meant to reduce packing time on multiprocessor
machines. The required amount of memory for the delta search window
is however multiplied by the number of threads.
+ Specifying 0 will cause git to auto-detect the number of CPU's
+ and set the number of threads accordingly.
pack.indexVersion::
Specify the default pack index version. Valid values are 1 for
archiving user's umask will be used instead. See umask(2) and
linkgit:git-archive[1].
+url.<base>.insteadOf::
+ Any URL that starts with this value will be rewritten to
+ start, instead, with <base>. In cases where some site serves a
+ large number of repositories, and serves them with multiple
+ access methods, and some users need to use different access
+ methods, this feature allows people to specify any of the
+ equivalent URLs and have git automatically rewrite the URL to
+ the best alternative for the particular user, even for a
+ never-before-seen repository on the site. When more than one
+ insteadOf strings match a given URL, the longest match is used.
+
user.email::
Your email address to be recorded in any newly created commits.
Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
Swap two inputs; that is, show differences from index or
on-disk file to tree contents.
+--relative[=<path>]::
+ When run from a subdirectory of the project, it can be
+ told to exclude changes outside the directory and show
+ pathnames relative to it with this option. When you are
+ not in a subdirectory (e.g. in a bare repository), you
+ can name which subdirectory to make the output relative
+ to by giving a <path> as an argument.
+
--text::
Treat all files as text.
Update only files that git already knows about. This is similar
to what "git commit -a" does in preparation for making a commit,
except that the update is limited to paths specified on the
- command line. If no paths are specified, all tracked files are
- updated.

+ current directory and its subdirectories are updated.
\--refresh::
Don't add the file(s), but only refresh their stat()
The command refuses to process new mailboxes while `.dotest`
directory exists, so if you decide to start over from scratch,
-run `rm -f .dotest` before running the command with mailbox

For whatever reason, direct connection between A and B is not allowed,
but we can move data from A to B via some mechanism (CD, email, etc).
We want to update R2 with developments made on branch master in R1.

+
+- Using temporally tags.

We set a tag in R1 (lastR2bundle) after the previous such transport,
and move it afterwards to help build the bundle.

-
------------
$ git-bundle create mybundle master ^lastR2bundle
$ git tag -f lastR2bundle master

-heads that exist both on the local side and on the remote
-side are updated.

+pushed: for every head that exists on the local side, the remote side is
+updated if a head of the same name already exists on the remote side.
+
`tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`.
+
include::urls-remotes.txt[]
+OUTPUT
+------
+
+The output of "git push" depends on the transport method used; this
+section describes the output when pushing over the git protocol (either
+locally or via ssh).
+
+The status of the push is output in tabular form, with each line
+representing the status of a single ref. Each line is of the form:
+
+-------------------------------
+ <flag> <summary> <from> -> <to> (<reason>)
+-------------------------------
+
+flag::
+ A single character indicating the status of the ref. This is
+ blank for a successfully pushed ref, `!` for a ref that was
+ rejected or failed to push, and '=' for a ref that was up to
+ date and did not need pushing (note that the status of up to
+ date refs is shown only when `git push` is running verbosely).
+
+summary::
+ For a successfully pushed ref, the summary shows the old and new
+ values of the ref in a form suitable for using as an argument to
+ `git log` (this is `<old>..<new>` in most cases, and
+ `<old>...<new>` for forced non-fast forward updates). For a
+ failed update, more details are given for the failure.
+ The string `rejected` indicates that git did not try to send the
+ ref at all (typically because it is not a fast forward). The
+ string `remote rejected` indicates that the remote end refused
+ the update; this rejection is typically caused by a hook on the
+ remote side. The string `remote failure` indicates that the
+ remote end did not report the successful update of the ref
+ (perhaps because of a temporary error on the remote side, a
+ break in the network connection, or other transient error).
+
+from::
+ The name of the local ref being pushed, minus its
+ `refs/<type>/` prefix. In the case of deletion, the
+ name of the local ref is omitted.
+
+to::
+ The name of the remote ref being updated, minus its
+ `refs/<type>/` prefix.
+
+reason::
+ A human-readable explanation. In the case of successfully pushed
+ refs, no explanation is needed. For a failed ref, the reason for
+ failure is described.

+Remotes configuration API
+=========================
+
+The API in remote.h gives access to the configuration related to
+remotes. It handles all three configuration mechanisms historically
+and currently used by git, and presents the information in a uniform
+fashion. Note that the code also handles plain URLs without any
+configuration, giving them just the default information.
+
+struct remote
+-------------
+
+`name`::
+
+ The user's nickname for the remote
+
+`url`::
+
+ An array of all of the url_nr URLs configured for the remote
+
+`push`::
+
+ An array of refspecs configured for pushing, with
+ push_refspec being the literal strings, and push_refspec_nr
+ being the quantity.
+
+`fetch`::
+
+ An array of refspecs configured for fetching, with
+ fetch_refspec being the literal strings, and fetch_refspec_nr
+ being the quantity.
+
+`fetch_tags`::
+
+ The setting for whether to fetch tags (as a separate rule from
+ the configured refspecs); -1 means never to fetch tags, 0
+ means to auto-follow tags based on the default heuristic, 1
+ means to always auto-follow tags, and 2 means to fetch all
+ tags.
+
+`receivepack`, `uploadpack`::
+
+ The configured helper programs to run on the remote side, for
+ git-native protocols.
+
+`http_proxy`::
+
+ The proxy to use for curl (http, https, ftp, etc.) URLs.
+
+struct remotes can be found by name with remote_get(), and iterated
+through with for_each_remote(). remote_get(NULL) will return the
+default remote, given the current branch and configuration.
+
+struct refspec
+--------------
+
+A struct refspec holds the parsed interpretation of a refspec. If it
+will force updates (starts with a '+'), force is true. If it is a
+pattern (sides end with '*') pattern is true. src and dest are the two
+sides (if a pattern, only the part outside of the wildcards); if there
+is only one side, it is src, and dst is NULL; if sides exist but are
+empty (i.e., the refspec either starts or ends with ':'), the
+corresponding side is "".
+
+This parsing can be done to an array of strings to give an array of
+struct refpsecs with parse_ref_spec().
+
+remote_find_tracking(), given a remote and a struct refspec with
+either src or dst filled out, will fill out the other such that the
+result is in the "fetch" specification for the remote (note that this
+evaluates patterns and returns a single result).
+
+struct branch
+-------------
+
+Note that this may end up moving to branch.h
+
+struct branch holds the configuration for a branch. It can be looked
+up with branch_get(name) for "refs/heads/{name}", or with
+branch_get(NULL) for HEAD.
+
+It contains:
+
+`name`::
+
+ The short name of the branch.
+
+`refname`::
+
+ The full path for the branch ref.
+
+`remote_name`::
+
+ The name of the remote listed in the configuration.
+
+`remote`::
+
+ The struct remote for that remote.
+
+`merge_name`::
+
+ An array of the "merge" lines in the configuration.
+
+`merge`::
+
+ An array of the struct refspecs used for the merge lines. That
+ is, merge[i]->dst is a local tracking ref which should be
+ merged into this branch by default.
+
+`merge_nr`::
+
+ The number of merge configurations
+
+branch_has_merge_config() returns true if the given branch has merge
+configuration given.
+
+Other stuff
+-----------
+
+There is other stuff in remote.h that is related, in general, to the
+process of interacting with remotes.
+
+(Daniel Barkalow)
run-command API
===============
-Talk about <run-command.h>, and things like:
+The run-command API offers a versatile tool to run sub-processes with
+redirected input and output as well as with a modified environment
+and an alternate current directory.
-* Environment the command runs with (e.g. GIT_DIR);
-* File descriptors and pipes;
-* Exit status;
+A similar API offers the capability to run a function asynchronously,
+which is primarily used to capture the output that the function
+produces in the caller in order to process it.
-(Hannes, Dscho, Shawn)
+
+Functions
+---------
+
+`start_command`::
+
+ Start a sub-process. Takes a pointer to a `struct child_process`
+ that specifies the details and returns pipe FDs (if requested).
+ See below for details.
+
+`finish_command`::
+
+ Wait for the completion of a sub-process that was started with
+ start_command().
+
+`run_command`::
+
+ A convenience function that encapsulates a sequence of
+ start_command() followed by finish_command(). Takes a pointer
+ to a `struct child_process` that specifies the details.
+
+`run_command_v_opt`, `run_command_v_opt_dir`, `run_command_v_opt_cd_env`::
+
+ Convenience functions that encapsulate a sequence of
+ start_command() followed by finish_command(). The argument argv
+ specifies the program and its arguments. The argument opt is zero
+ or more of the flags `RUN_COMMAND_NO_STDIN`, `RUN_GIT_CMD`, or
+ `RUN_COMMAND_STDOUT_TO_STDERR` that correspond to the members
+ .no_stdin, .git_cmd, .stdout_to_stderr of `struct child_process`.
+ The argument dir corresponds the member .dir. The argument env
+ corresponds to the member .env.
+
+`start_async`::
+
+ Run a function asynchronously. Takes a pointer to a `struct
+ async` that specifies the details and returns a pipe FD
+ from which the caller reads. See below for details.
+
+`finish_async`::
+
+ Wait for the completeion of an asynchronous function that was
+ started with start_async().
+
+
+Data structures
+---------------
+
+* `struct child_process`
+
+This describes the arguments, redirections, and environment of a
+command to run in a sub-process.
+
+The caller:
+
+1. allocates and clears (memset(&chld, '0', sizeof(chld));) a
+ struct child_process variable;
+2. initializes the members;
+3. calls start_command();
+4. processes the data;
+5. closes file descriptors (if necessary; see below);
+6. calls finish_command().
+
+The .argv member is set up as an array of string pointers (NULL
+terminated), of which .argv[0] is the program name to run (usually
+without a path). If the command to run is a git command, set argv[0] to
+the command name without the 'git-' prefix and set .git_cmd = 1.
+
+The members .in, .out, .err are used to redirect stdin, stdout,
+stderr as follows:
+
+. Specify 0 to request no special redirection. No new file descriptor
+ is allocated. The child process simply inherits the channel from the
+ parent.
+
+. Specify -1 to have a pipe allocated; start_command() replaces -1
+ by the pipe FD in the following way:
+
+ .in: Returns the writable pipe end into which the caller writes;
+ the readable end of the pipe becomes the child's stdin.
+
+ .out, .err: Returns the readable pipe end from which the caller
+ reads; the writable end of the pipe end becomes child's
+ stdout/stderr.
+
+ The caller of start_command() must close the so returned FDs
+ after it has completed reading from/writing to it!
+
+. Specify a file descriptor > 0 to be used by the child:
+
+ .in: The FD must be readable; it becomes child's stdin.
+ .out: The FD must be writable; it becomes child's stdout.
+ .err > 0 is not supported.
+
+ The specified FD is closed by start_command(), even if it fails to
+ run the sub-process!
+
+. Special forms of redirection are available by setting these members
+ to 1:
+
+ .no_stdin, .no_stdout, .no_stderr: The respective channel is
+ redirected to /dev/null.
+
+ .stdout_to_stderr: stdout of the child is redirected to the
+ parent's stderr (i.e. *not* to what .err or
+ .no_stderr specify).
+
+To modify the environment of the sub-process, specify an array of
+string pointers (NULL terminated) in .env:
+
+. If the string is of the form "VAR=value", i.e. it contains '='
+ the variable is added to the child process's environment.
+
+. If the string does not contain '=', it names an environement
+ variable that will be removed from the child process's envionment.
+
+To specify a new initial working directory for the sub-process,
+specify it in the .dir member.
+
+
+* `struct async`
+
+This describes a function to run asynchronously, whose purpose is
+to produce output that the caller reads.
+
+The caller:
+
+1. allocates and clears (memset(&asy, '0', sizeof(asy));) a
+ struct async variable;
+2. initializes .proc and .data;
+3. calls start_async();
+4. processes the data by reading from the fd in .out;
+5. closes .out;
+6. calls finish_async().
+
+The function pointer in .proc has the following signature:
+
+ int proc(int fd, void *data);
+
+. fd specifies a writable file descriptor to which the function must
+ write the data that it produces. The function *must* close this
+ descriptor before it returns.
+
+. data is the value that the caller has specified in the .data member
+ of struct async.
+
+. The return value of the function is 0 on success and non-zero
+ on failure. If the function indicates failure, finish_async() will
+ report failure as well.
+
+
+There are serious restrictions on what the asynchronous function can do
+because this facility is implemented by a pipe to a forked process on
+UNIX, but by a thread in the same address space on Windows:
+
+. It cannot change the program's state (global variables, environment,
+ etc.) in a way that the caller notices; in other words, .out is the
+ only communication channel to the caller.
+
+. It must not change the program's state that the caller of the
+ facility also uses.

They are equivalent, except the former implies --local option.
endif::git-clone[]
+
+
+If there are a large number of similarly-named remote repositories and
+you want to use a different format for them (such that the URLs you
+use will be rewritten into URLs that work), you can create a
+configuration section of the form:
+
+------------
+ [url "<actual url base>"]
+ insteadOf = <other url base>
+------------
+
+For example, with this:
+
+------------
+ [url "git://git.host.xz/"]
+ insteadOf = host.xz:/path/to/
+ insteadOf = work:
+------------
+
+a URL like "work:repo.git" or like "host.xz:/path/to/repo.git" will be
+rewritten in any context that takes a URL to be "git://git.host.xz/repo.git".

+- Rename git-core to just git and rename meta package from git to git-all.
+
* Sun Feb 03 2008 James Bowes <jbowes@dangerouslyinc.com>
- Add a BuildRequires for gettext
Displayed in the project summary page. You can use multiple-valued
gitweb.url repository configuration variable for that, but the file
takes precendence.
+ * gitweb.owner
+ You can use the gitweb.owner repository configuration variable to set
+ repository's owner. It is displayed in the project list and summary
+ page. If it's not set, filesystem directory's owner is used.
* various gitweb.* config variables (in config)
