The only differences in behavior should be:
- git checkout -m with non-trivial merging won't print out
merge-recursive messages (see the change in t7201-co.sh)
- git checkout -- paths... will give a sensible error message if
HEAD is invalid as a commit.
- some intermediate states which were written to disk in the shell
version (in particular, index states) are only kept in memory in
this version, and therefore these can no longer be revealed by
later write operations becoming impossible.
- when we change branches, we discard MERGE_MSG, SQUASH_MSG, and
rr-cache/MERGE_RR, like reset always has.
I'm not 100% sure I got the merge recursive setup exactly right; the
base for a non-trivial merge in the shell code doesn't seem
theoretically justified to me, but I tried to match it anyway, and the
tests all pass this way.
Other than these items, the results should be identical to the shell
version, so far as I can tell.

This makes write_tree_from_memory(), which writes the active cache as
a tree and returns the struct tree for it, available to other code. It
also makes available merge_trees(), which does the internal merge of
two trees with a known base, and merge_recursive(), which does the
recursive internal merge of two commits with a list of common
ancestors.
The first two of these will be used by checkout -m, and the third is
presumably useful in general, although the implementation of checkout
-m which entirely matches the behavior of the shell version does not
use it (since it ignores the difference of ancestry between the old
branch and the new branch).

The original "rewrite in C" did somewhat a sloppy job while
stealing code from git-write-tree.
The caller pretends as if the write_tree() function would return
an error code and being able to issue a sensible error message
itself, but write_tree() function just calls die() and never
returns an error. Worse yet, the function claims that it was
running git-write-tree (which is no longer true after
cherry-pick stole it).

This program dumps (parts of) a git repository in the format that
fast-import understands.
For clarity's sake, it does not use the 'inline' method of specifying
blobs in the commits, but builds the blobs before building the commits.
Since signed tags' signatures will not necessarily be valid (think
transformations after the export, or excluding revisions, changing
the history), there are 4 modes to handle them: abort (default),
ignore, warn and strip. The latter just turns the tags into
unsigned ones.

This replaces git-clean.sh with builtin-clean.c, and moves
git-clean.sh to the examples.
This also introduces a change in behavior when removing directories
explicitly specified as a path. For example currently:
1. When dir has only untracked files, these two behave differently:
$ git clean -n dir
$ git clean -n dir/
the former says "Would not remove dir/", while the latter would say
"Would remove dir/untracked" for all paths under it, but not the
directory itself.
With -d, the former would stop refusing, however since the user
explicitly asked to remove the directory the -d is no longer required.
2. When there are more parameters:
$ git clean -n dir foo
$ git clean -n dir/ foo
both cases refuse to remove dir/ unless -d is specified. Once again
since both cases requested to remove dir the -d is no longer required.

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 -
index - X X X

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.

The existing test suite for "git tag" guarantees the compatibility

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 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.

This prepares a place to collect reflog management subcommands,

$ git reflog expire --dry-run \

--expire-unreachable=1.week \
refs/heads/master
The expiration uses two timestamps: --expire and --expire-unreachable.
Entries older than expire time (defaults to 90 days), and entries older
than expire-unreachable time (defaults to 30 days) and records a commit
that has been rewound and made unreachable from the current tip of the
ref are removed from the reflog.
The parameter handling is still rough, but I think the
core logic for expiration is already sound.

This also adds some very rudimentary support for the notion of packed
refs. HOWEVER! At this point it isn't used to actually look up a ref
yet, only for listing them (ie "for_each_ref()" and friends see the
packed refs, but none of the other single-ref lookup routines).
Note how we keep two separate lists: one for the loose refs, and one for
the packed refs we read. That's so that we can easily keep the two apart,
and read only one set or the other (and still always make sure that the
loose refs take precedence).
[ From this, it's not actually obvious why we'd keep the two separate
lists, but it's important to have the packed refs on their own list
later on, when I add support for looking up a single loose one.
For that case, we will want to read _just_ the packed refs in case the
single-ref lookup fails, yet we may end up needing the other list at
some point in the future, so keeping them separated is important ]

It's kind of like "git peek-remote", but works only locally (and thus
avoids the whole overhead of git_connect()) and has some extra
verification features.
For example, it allows you to filter the results, and to choose whether
you want the tag dereferencing or not. You can also use it to just test
whether a particular ref exists.
For example:
git show-ref master
will show all references called "master", whether tags or heads or
anything else, and regardless of how deep in the reference naming
hierarchy they are (so it would show "refs/heads/master" but also
"refs/remote/other-repo/master").
When using the "--verify" flag, the command requires an exact ref path:
git show-ref --verify refs/heads/master
will only match the exact branch called "master".
If nothing matches, show-ref will return an error code of 1, and in the
case of verification, it will show an error message.
For scripting, you can ask it to be quiet with the "--quiet" flag, which
allows you to do things like
git-show-ref --quiet --verify -- "refs/heads/$headname" ||
echo "$headname is not a valid branch"
to check whether a particular branch exists or not (notice how we don't
actually want to show any results, and we want to use the full refname for
it in order to not trigger the problem with ambiguous partial matches).
To show only tags, or only proper branch heads, use "--tags" and/or
"--heads" respectively (using both means that it shows tags _and_ heads,
but not other random references under the refs/ subdirectory).
To do automatic tag object dereferencing, use the "-d" or "--dereference"
flag, so you can do
git show-ref --tags --dereference
to get a listing of all tags together with what they dereference.
