We need to correctly set up $PATH for non-c based git commands.
Since we already do this, we can just use that $PATH and execvp,
instead of looping over the paths with execve.
This patch adds a setup_path() function to exec_cmd.c, which sets
the $PATH order correctly for our search order. execv_git_cmd() is
stripped down to setting up argv and calling execvp(). git.c's
main() only only needs to call setup_path().

Thanks to Johannes Schindelin for review and fixes, and Julian
Phillips for the original C translation.
This changes a few small bits of behavior:
branch.<name>.merge is parsed as if it were the lhs of a fetch
refspec, and does not have to exactly match the actual lhs of a
refspec, so long as it is a valid abbreviation for the same ref.
branch.<name>.merge is no longer ignored if the remote is configured
with a branches/* file. Neither behavior is useful, because there can
only be one ref that gets fetched, but this is more consistant.
Also, fetch prints different information to standard out.

This replaces the script "git-reset.sh" with "builtin-reset.c".
A few git commands used in the script are called from the builtin also:
"ls-files" to check for unmerged files, "read-tree" for resetting
the index file in "mixed" and "hard" resets, and "update-index" to
refresh at the end in the "mixed" reset and also for the option that
gets selected paths into the index.
The reset option with paths was implemented by Johannes Schindelin.
Since the option that gets selected paths into the index is not
a "reset" like the others because it does not change the HEAD at all,
now the command is showing a warning when the "--mixed" option
is supplied for that purpose.
The following table shows the behaviour of "git reset" for
the different supported options, where X means "changing"
the HEAD, index or working tree:
reset: --soft --mixed --hard -- <paths>
HEAD X X X -

Here is my attempt to fix this with a minimally intrusive patch.
* As "git --bare init" cannot tell if it was called with --bare or
just "GIT_DIR=. git init", I added an explicit assignment of
is_bare_repository_cfg on the codepath for "git --bare".
* GIT_WORK_TREE alone without GIT_DIR does not make any sense,
nor GIT_WORK_TREE with an explicit "git --bare". Catch that
mistake. It might make sense to move this check to "git.c"
side as well, but I tried to shoot for the minimum change for
now.
* Some scripts, especially from the olden days, rely on
traditional GIT_DIR behaviour in "git init". Namely, these
are some notable patterns:
(create a bare repository)
- mkdir some.git && cd some.git && GIT_DIR=. git init
- mkdir some.git && cd some.git && git --bare init
(create a non-bare repository)
- mkdir .git && GIT_DIR=.git git init
- mkdir .git && GIT_DIR=`pwd`/.git git init
This comes with a new test script and also passes the existing
test suite, but there may be cases that are still broken with
the current tip of master and this patch does not yet fix. I'd
appreciate help in straightening this mess out.

The old version of work-tree support was an unholy mess, barely readable,
and not to the point.
For example, why do you have to provide a worktree, when it is not used?
As in "git status". Now it works.
Another riddle was: if you can have work trees inside the git dir, why
are some programs complaining that they need a work tree?
IOW it is allowed to call
$ git --git-dir=../ --work-tree=. bla
when you really want to. In this case, you are both in the git directory
and in the working tree. So, programs have to actually test for the right
thing, namely if they are inside a working tree, and not if they are
inside a git directory.
Also, GIT_DIR=../.git should behave the same as if no GIT_DIR was
specified, unless there is a repository in the current working directory.
It does now.
The logic to determine if a repository is bare, or has a work tree
(tertium non datur), is this:
--work-tree=bla overrides GIT_WORK_TREE, which overrides core.bare = true,
which overrides core.worktree, which overrides GIT_DIR/.. when GIT_DIR
ends in /.git, which overrides the directory in which .git/ was found.
In related news, a long standing bug was fixed: when in .git/bla/x.git/,
which is a bare repository, git formerly assumed ../.. to be the
appropriate git dir. This problem was reported by Shawn Pearce to have
caused much pain, where a colleague mistakenly ran "git init" in "/" a
long time ago, and bare repositories just would not work.

This replaces "git-verify-tag.sh" with "builtin-verify-tag.c".
Testing relies on the "git tag -v" tests calling this command.
A temporary file is needed when calling to gpg, because git is
already creating detached signatures (gpg option -b) to sign tags
(instead of leaving gpg to add the signature to the file by itself),
and those signatures need to be supplied in a separate file to be
verified by gpg.
The program uses git_mkstemp to create that temporary file needed by
gpg, instead of the previously used "$GIT_DIR/.tmp-vtag", in order to
allow the command to be used in read-only repositories, and also
prevent other instances of git to read or remove the same file.
Signal SIGPIPE is ignored because the program sometimes was
terminated because that signal when writing the input for gpg.
The command now can receive many tag names to be verified.
Documentation is also updated here to reflect this new behaviour.

This replaces the script "git-tag.sh" with "builtin-tag.c".
The existing test suite for "git tag" guarantees the compatibility
with the features provided by the script version.
There are some minor changes in the behaviour of "git tag" here:
"git tag -v" now can get more than one tag to verify, like "git tag -d" does,
"git tag" with no arguments prints all tags, more like "git branch" does,
and "git tag -n" also prints all tags with annotations (without needing -l).
Tests and documentation were also updated to reflect these changes.
The program is currently calling the script "git verify-tag" for verify.
This can be changed porting it to C and calling its functions directly
from builtin-tag.c.

This switches the checks around upon the exit codepath of the
git wrapper, so that we may recover at least non-transient errors.
It's still not perfect. As I've been harping on, stdio simply isn't very
good for error reporting. For example, if an IO error happened, you'd want
to see EIO, wouldn't you? And yes, that's what the kernel would return.
However, with buffered stdio (and flushing outside of our control), what
would likely happen is that some intermediate error return _does_ return
EIO, but then the kernel might decide to re-mount the filesystem read-only
due to the error, and the actual *report* for us might be
"write failure on standard output: read-only filesystem"
which lost the EIO.

Aliases changing environment variables (GIT_DIR or

git has to use GIT_DIR to read the aliases from the config.
After running handle_options for the alias the options of the

through getenv earlier may contain the old value or the new

setup_gdg is used as abbreviation for setup_git_directory_gently.
The work tree can be specified using the environment variable
GIT_WORK_TREE and the config option core.worktree (the environment
variable has precendence over the config option). Additionally
there is a command line option --work-tree which sets the
environment variable.
setup_gdg does the following now:
GIT_DIR unspecified
repository in .git directory
parent directory of the .git directory is used as work tree,
GIT_WORK_TREE is ignored
GIT_DIR unspecified
repository in cwd
GIT_DIR is set to cwd
see the cases with GIT_DIR specified what happens next and
also see the note below
GIT_DIR specified
GIT_WORK_TREE/core.worktree unspecified
cwd is used as work tree
GIT_DIR specified
GIT_WORK_TREE/core.worktree specified
the specified work tree is used
Note on the case where GIT_DIR is unspecified and repository is in cwd:
GIT_WORK_TREE is used but is_inside_git_dir is always true.
I did it this way because setup_gdg might be called multiple
times (e.g. when doing alias expansion) and in successive calls
setup_gdg should do the same thing every time.
Meaning of is_bare/is_inside_work_tree/is_inside_git_dir:
(1) is_bare_repository
A repository is bare if core.bare is true or core.bare is
unspecified and the name suggests it is bare (directory not
named .git). The bare option disables a few protective
checks which are useful with a working tree. Currently
this changes if a repository is bare:
updates of HEAD are allowed
git gc packs the refs
the reflog is disabled by default
(2) is_inside_work_tree
True if the cwd is inside the associated working tree (if there
is one), false otherwise.
(3) is_inside_git_dir
True if the cwd is inside the git directory, false otherwise.
Before this patch is_inside_git_dir was always true for bare
repositories.
When setup_gdg finds a repository git_config(git_default_config) is
always called. This ensure that is_bare_repository makes use of
core.bare and does not guess even though core.bare is specified.
inside_work_tree and inside_git_dir are set if setup_gdg finds a
repository. The is_inside_work_tree and is_inside_git_dir functions
will die if they are called before a successful call to setup_gdg.

This adds the basic infrastructure to assign attributes to
paths, in a way similar to what the exclusion mechanism does
based on $GIT_DIR/info/exclude and .gitignore files.
An attribute is just a simple string that does not contain any
whitespace. They can be specified in $GIT_DIR/info/attributes
file, and .gitattributes file in each directory.
Each line in these files defines a pattern matching rule.
Similar to the exclusion mechanism, a later match overrides an
earlier match in the same file, and entries from .gitattributes
file in the same directory takes precedence over the ones from
parent directories. Lines in $GIT_DIR/info/attributes file are
used as the lowest precedence default rules.
A line is either a comment (an empty line, or a line that begins
with a '#'), or a rule, which is a whitespace separated list of
tokens. The first token on the line is a shell glob pattern.
The rest are names of attributes, each of which can optionally
be prefixed with '!'. Such a line means "if a path matches this
glob, this attribute is set (or unset -- if the attribute name
is prefixed with '!'). For glob matching, the same "if the
pattern does not have a slash in it, the basename of the path is
matched with fnmatch(3) against the pattern, otherwise, the path
is matched with the pattern with FNM_PATHNAME" rule as the
exclusion mechanism is used.
This does not define what an attribute means. Tying an
attribute to various effects it has on git operation for paths
that have it will be specified separately.

Some workflows require use of repositories on machines that cannot be
connected, preventing use of git-fetch / git-push to transport objects and
references between the repositories.
git-bundle provides an alternate transport mechanism, effectively allowing
git-fetch and git-pull to operate using sneakernet transport. `git-bundle
create` allows the user to create a bundle containing one or more branches
or tags, but with specified basis assumed to exist on the target
repository. At the receiving end, git-bundle acts like git-fetch-pack,
allowing the user to invoke git-fetch or git-pull using the bundle file as
the URL. git-fetch and git-ls-remote determine they have a bundle URL by
checking that the URL points to a file, but are otherwise unchanged in
operation with bundles.
The original patch was done by Mark Levedahl <mdl123@verizon.net>.
It was updated to make git-bundle a builtin, and get rid of the tar
format: now, the first line is supposed to say "# v2 git bundle", the next
lines either contain a prerequisite ("-" followed by the hash of the
needed commit), or a ref (the hash of a commit, followed by the name of
the ref), and finally the pack. As a result, the bundle argument can be
"-" now.

With this flag and given two paths, git-diff-files behaves as a GNU diff
lookalike (plus the git goodies like --check, colour, etc.). This flag
is also available in git-diff. It also works outside of a git repository.
In addition, if git-diff{,-files} is called without revision or stage
parameter, and with exactly two paths at least one of which is not tracked,
the default is --no-index.
So, you can now say
git diff /etc/inittab /etc/fstab
