Resetting with paths does not update HEAD and there is nothing else
that a commit should be needed for. Relax the argument parsing so only
a tree is required.
The sha1 is only passed to read_from_tree(), which already only
requires a tree.
The "rev" variable we pass to run_add_interactive() will resolve to a
tree. This is fine since interactive_reset only needs the parameter to
be a treeish and doesn't use it for display purposes.

When doing a mixed reset without paths, the index is locked, read,
reset, and written back as part of the actual reset operation (in
reset_index()). Then, when showing the list of worktree modifications,
we lock the index again, refresh it, and write it.
Change this so we only write the index once, making "git reset" a
little faster. It does mean that the index lock will be held a little
longer, but the difference is small compared to the time spent
refreshing the index.
There is one minor functional difference: We used to say "Could not
write new index file." if the first write failed, and "Could not
refresh index" if the second write failed. Now, we will only use the
first message.
This speeds up "git reset" a little on the linux-2.6 repo (best of
five, warm cache):

In preparation for the/a following patch, move the locking, writing
and committing of the index file out of update_index_refresh(). The
code duplication caused will soon be taken care of. What remains of
update_index_refresh() is just one line, but it is still called from
two places, so let's leave it for now.
In the process, we expose and fix the minor UI bug that makes us print
"Could not refresh index" when we fail to write the index file when
invoked with a pathspec. Copy the error message from the pathspec-less
codepath ("Could not write new index file.").

where read_from_tree() internally also calls

"git reset --keep" calls reset_index_file() twice, first doing a
two-way merge to the target revision, updating the index and worktree,
and then resetting the index. After each call, we write the index
file.
In the unlikely event that the second call to reset_index_file()
fails, the index will have been merged to the target revision, but
HEAD will not be updated, leaving the user with a dirty index.
By moving the locking, writing and committing out of
reset_index_file() and into the caller, we can avoid writing the index
twice, thereby making the sure we don't end up in the half-way reset
state. As a bonus, we speed up "git reset --keep" a little on the

Running e.g. "git reset ." in a bare repo results in an index file
being created from the HEAD commit. The differences compared to the
index are then printed as usual, but since there is no worktree, it
will appear as if all files are deleted. For example, in a bare clone
of git.git:
Unstaged changes after reset:
D .gitattributes
D .gitignore
D .mailmap
...
This happens because the check for is_bare_repository() happens after
we branch off into read_from_tree() to reset with paths. Fix by moving
the branching point after the check.

We use the path arguments in two places in reset.c: in

get_pathspec(), so we pass the (prefix, argv) pair to both
functions. Move the call to get_pathspec() out of these methods, for
two reasons: 1) One argument is simpler than two. 2) It lets us use

"git reset $pathspec" currently exits with a non-zero exit code if the
worktree is dirty after resetting, which is inconsistent with reset
without pathspec, and it makes it harder to know whether the command
really failed. Change it to exit with code 0 regardless of whether the
worktree is dirty so that non-zero indicates an error.
This makes the 4 "disambiguation" test cases in t7102 clearer since
they all used to "fail", 3 of which "failed" due to changes in the

Create find_hook() function to determine if a given hook exists and is
executable. If it is, the path to the script will be returned,
otherwise NULL is returned.
This encapsulates the tests that are used to check for the existence of
a hook in one place, making it easier to modify those checks if that is
found to be necessary. This also makes it simple for places that can
use a hook to check if a hook exists before doing, possibly lengthy,
setup work which would be pointless if no such hook is present.
The returned value is left as a static value from get_pathname() rather
than a duplicate because it is anticipated that the return value will
either be used as a boolean, immediately added to an argv_array list
which would result in it being duplicated at that point, or used to
actually run the command without much intervening work. Callers which
need to hold onto the returned value for a longer time are expected to

(1) Only print out the names of the files and directories that got
actually deleted. Also do not mention that we are not removing
directories when the user did not ask us to do so with '-d'.
(2) Show ignore message for skipped untracked git repositories.
Consider the following repo layout:
test.git/
|-- tracked_dir/
| |-- some_tracked_file
| |-- some_untracked_file
|-- tracked_file
|-- untracked_file
|-- untracked_foo/
| |-- bar/
| | |-- bar.txt
| |-- emptydir/
| |-- frotz.git/
| |-- frotz.tx
|-- untracked_some.git/
|-- some.txt
Suppose the user issues 'git clean -fd' from the test.git directory.
When -d option is used and untracked directory 'foo' contains a
subdirectory 'frotz.git' that is managed by a different git repository
therefore it will not be removed.
$ git clean -fd
Removing tracked_dir/some_untracked_file
Removing untracked_file
Removing untracked_foo/
Removing untracked_some.git/
The message displayed to the user is slightly misleading. The foo/
directory has not been removed because of foo/frotz.git still exists.
On the other hand the subdirectories 'bar' and 'emptydir' have been
deleted but they're not mentioned anywhere. Also, untracked_some.git
has not been removed either.
This behaviour is the result of the way the deletion of untracked
directories are reported. In the current implementation they are
deleted recursively but only the name of the top most directory is
printed out. The calling function does not know about any
subdirectories that could not be removed during the recursion.
Improve the way the deleted directories are reported back to
the user:
(1) Create a recursive delete function 'remove_dirs' in builtin/clean.c
to run in both dry_run and delete modes with the delete logic as
follows:
(a) Check if the current directory to be deleted is an untracked
git repository. If it is and --force --force option is not set
do not touch this directory, print ignore message, set dir_gone
flag to false for the caller and return.
(b) Otherwise for each item in current directory:
(i) If current directory cannot be accessed, print warning,
set dir_gone flag to false and return.
(ii) If the item is a subdirectory recurse into it,
check for the returned value of the dir_gone flag.
If the subdirectory is gone, add the name of the deleted
directory to a list of successfully removed items 'dels'.
Else set the dir_gone flag as the current directory
cannot be removed because we have at least one subdirectory
hanging around.
(iii) If it is a file try to remove it. If success add the
file name to the 'dels' list, else print error and set
dir_gone flag to false.
(c) After we finished deleting all items in the current directory and
the dir_gone flag is still true, remove the directory itself.
If failed set the dir_gone flag to false.
(d) If the current directory cannot be deleted because the dir_gone flag
has been set to false, print out all the successfully deleted items
for this directory from the 'dels' list.
(e) We're done with the current directory, return.
(2) Modify the cmd_clean() function to:
(a) call the recursive delete function 'remove_dirs()' for each
topmost directory it wants to remove
(b) check for the returned value of dir_gone flag. If it's true
print the name of the directory as being removed.
Consider the output of the improved version:
$ git clean -fd
Removing tracked_dir/some_untracked_file
Removing untracked_file
Skipping repository untracked_foo/frotz.git
Removing untracked_foo/bar
Removing untracked_foo/emptydir
Skipping repository untracked_some.git/
Now it displays only the file and directory names that got actually
deleted and shows the name of the untracked git repositories it ignored.

The user can do --depth=2147483647 (*) for restoring complete repo

longest commit chain in the repository would also do, but some
guessing may be involved. Make easy-to-remember --unshallow an alias
for --depth=2147483647.
Make upload-pack recognize this special number as infinite depth. The
effect is essentially the same as before, except that upload-pack is
more efficient because it does not have to traverse to the bottom
anymore.
The chance of a user actually wanting exactly 2147483647 commits
depth, not infinite, on a repository with a history that long, is
probably too small to consider. The client can learn to add or
subtract one commit to avoid the special treatment when that actually
happens.

Previously each exclude_list could potentially contain patterns
from multiple sources. For example dir->exclude_list[EXC_FILE]
would typically contain patterns from .git/info/exclude and
core.excludesfile, and dir->exclude_list[EXC_DIRS] could contain
patterns from multiple per-directory .gitignore files during
directory traversal (i.e. when dir->exclude_stack was more than
one item deep).
We split these composite exclude_lists up into three groups of
exclude_lists (EXC_CMDL / EXC_DIRS / EXC_FILE as before), so that each
exclude_list now contains patterns from a single source. This will
allow us to cleanly track the origin of each pattern simply by adding
a src field to struct exclude_list, rather than to struct exclude,
which would make memory management of the source string tricky in the
EXC_DIRS case where its contents are dynamically generated.
Similarly, by moving the filebuf member from struct exclude_stack to
struct exclude_list, it allows us to track and subsequently free
memory buffers allocated during the parsing of all exclude files,
rather than only tracking buffers allocated for files in the EXC_DIRS
group.

git clone supports the --separate-git-dir option to create the git dir

to revive the submodule from there, which then fails with a not very user
friendly error message.
Fix that by updating the junk_git_dir variable (used to remember if and
what git dir should be removed in case of failure) to the new value given
with the --seperate-git-dir option. Also add a test for this to t5600 (and
while at it fix the former last test to not cd into a directory to test
for its existence but use "test -d" instead).

65969d4 (merge: honor prepare-commit-msg hook, 2011-02-14) tried to
make "git commit" and "git merge" consistent, because a merge that
required user assistance has to be concluded with "git commit", but
back then only "git commit" triggered prepare-commit-msg hook.
When it added a call to run the prepare-commit-msg hook, however, it
forgot to check the exit code from the hook like "git commit" does,
and ended up replacing one inconsistency with another.
When prepare-commit-msg hook that is run from "git merge" exits with

The previous commit documented two known breakages revolving around
a case where one side flips a tree into a blob (or vice versa),
where the original code simply gets confused and feeds a mixture of
trees and blobs into either the recursive merge-tree (and recursing
into the blob will fail) or three-way merge (and merging tree contents
together with blobs will fail).
Fix it by feeding trees (and only trees) into the recursive
merge-tree machinery and blobs (and only blobs) into the three-way
content level merge machinery separately; when this happens, the
entire merge has to be marked as conflicting at the structure level.

The --reroll-count=$N option, when given a positive integer:
- Adds " v$N" to the subject prefix specified. As the default
subject prefix string is "PATCH", --reroll-count=2 makes it
"PATCH v2".
- Prefixes "v$N-" to the names used for output files. The cover
letter, whose name is usually 0000-cover-letter.patch, becomes
v2-0000-cover-letter.patch when given --reroll-count=2.
This allows users to use the same --output-directory for multiple
iterations of the same series, without letting the output for a
newer round overwrite output files from the earlier rounds. The
user can incorporate materials from earlier rounds to update the
newly minted iteration, and use "send-email v2-*.patch" to send out

When an object has already been exported (and thus is in the marks) it's
flagged as SHOWN, so it will not be exported again, even if in a later
time it's exported through a different ref.
We don't need the object to be exported again, but we want the ref
updated, which doesn't happen.
Since we can't know if a ref was exported or not, let's just assume that
if the commit was marked (flags & SHOWN), the user still wants the ref
updated.
IOW: If it's specified in the command line, it will get updated,
regardless of whether or not the object was marked.
So:
% git branch test master
% git fast-export $mark_flags master
% git fast-export $mark_flags test
Would export 'test' properly.
Additionally, this fixes issues with remote helpers; now they can push
refs whose objects have already been exported, and a few other issues as
well. Update the tests accordingly.

They have been marked as UNINTERESTING for a reason, lets respect
that. Currently the first ref is handled properly, but not the
rest. Assuming that all the refs point at the same commit in the
following example:
% git fast-export master ^uninteresting ^foo ^bar
reset refs/heads/bar
from :0
reset refs/heads/foo
from :0
reset refs/heads/uninteresting
from :0
% git fast-export ^uninteresting ^foo ^bar master
reset refs/heads/master
from :0
reset refs/heads/bar
from :0
reset refs/heads/foo
from :0
Clearly this is wrong; the negative refs should be ignored.
After this patch:
% git fast-export ^uninteresting ^foo ^bar master
# nothing
% git fast-export master ^uninteresting ^foo ^bar
# nothing
And even more, it would only happen if the ref is pointing to exactly
the same commit, but not otherwise:
% git fast-export ^next next
reset refs/heads/next
from :0
% git fast-export ^next next^{commit}
# nothing
% git fast-export ^next next~0
# nothing
% git fast-export ^next next~1
# nothing
% git fast-export ^next next~2
# nothing
The reason this happens is that before traversing the commits,
fast-export checks if any of the refs point to the same object, and any
duplicated ref gets added to a list in order to issue 'reset' commands
after the traversing. Unfortunately, it's not even checking if the
commit is flagged as UNINTERESTING. The fix of course, is to check it.
However, in order to do it properly we need to get the UNINTERESTING
flag from the command line, not from the commit object, because
"^foo bar" will mark the commit 'bar' uninteresting if foo and bar
points at the same commit. rev_cmdline_info, which was introduced
exactly to handle this situation, contains all the information we
need for get_tags_and_duplicates(), plus the ref flag. This way the
rest of the positive refs will remain untouched; it's only the
negative ones that change in behavior.

Doing a "git rm submod/" on a submodule results in an error:
fatal: pathspec 'submod/' did not match any files
This is really inconvenient as e.g. using TAB completion in a shell on a
submodule automatically adds the trailing '/' when it completes the path
of the submodule directory. The user has then to remove the '/' herself to
make a "git rm" succeed. Doing a "git rm -r somedir/" is working fine, so
there is no reason why that shouldn't work for submodules too.
Teach git rm to not error out when a '/' is appended to the path of a
submodule. Achieve this by chopping off trailing slashes from the path
names given if they represent directories. Add tests to make sure that
logic only applies to directories and not to files.

We keep track of whether the user ident was given to us
explicitly, or if we guessed at it from system parameters
like username and hostname. However, we kept only a single
variable. This covers the common cases (because the author
and committer will usually come from the same explicit
source), but can miss two cases:
1. GIT_COMMITTER_* is set explicitly, but we fallback for
GIT_AUTHOR. We claim the ident is explicit, even though
the author is not.
2. GIT_AUTHOR_* is set and we ask for author ident, but
not committer ident. We will claim the ident is
implicit, even though it is explicit.
This patch uses two variables instead of one, updates both
when we set the "fallback" values, and updates them
individually when we read from the environment.
Rather than keep user_ident_sufficiently_given as a
compatibility wrapper, we update the only two callers to
check the committer_ident, which matches their intent and

The git-config command has always implemented its own file
lookup and parsing order. This was necessary because its
duplicate-entry handling did not match the way git's
internal callbacks worked. Now that this is no longer the
case, we are free to reuse the existing parsing code.
This saves us a few lines of code, but most importantly, it
means that the logic for which files are examined is
contained only in one place and cannot diverge.

If git-config is asked for a single value, it will complain
and exit with an error if it finds multiple instances of
that value. This is unlike the usual internal config
parsing, however, which will generally overwrite previous
values, leaving only the final one. For example:
[set a multivar]
$ git config user.email one@example.com
$ git config --add user.email two@example.com
[use the internal parser to fetch it]
$ git var GIT_AUTHOR_IDENT
Your Name <two@example.com> ...
[use git-config to fetch it]
$ git config user.email
one@example.com
error: More than one value for the key user.email: two@example.com
This overwriting behavior is critical for the regular
parser, which starts with the lowest-priority file (e.g.,
/etc/gitconfig) and proceeds to the highest-priority file
($GIT_DIR/config). Overwriting yields the highest priority
value at the end.
Git-config solves this problem by implementing its own
parsing. It goes from highest to lowest priorty, but does
not proceed to the next file if it has seen a value.
So in practice, this distinction never mattered much,
because it only triggered for values in the same file. And
there was not much point in doing that; the real value is in
overwriting values from lower-priority files.
However, this changed with the implementation of config
include files. Now we might see an include overriding a
value from the parent file, which is a sensible thing to do,
but git-config will flag as a duplication.
This patch drops the duplicate detection for git-config and
switches to a pure-overwrite model (for the single case;
--get-all can still be used if callers want to do something
more fancy).
As is shown by the modifications to the test suite, this is
a user-visible change in behavior. An alternative would be
to just change the include case, but this is much cleaner
for a few reasons:
1. If you change the include case, then to what? If you
just stop parsing includes after getting a value, then
you will get a _different_ answer than the regular
config parser (you'll get the first value instead of
the last value). So you'd want to implement overwrite
semantics anyway.
2. Even though it is a change in behavior for git-config,
it is bringing us in line with what the internal
parsers already do.
3. The file-order reimplementation is the only thing
keeping us from sharing more code with the internal
config parser, which will help keep differences to a
minimum.
Going under the assumption that the primary purpose of
git-config is to behave identically to how git's internal
parsing works, this change can be seen as a bug-fix.

This is a refactor that will allow us to more easily tweak
the behavior for multi-valued variables, and it will
ultimately allow us to remove a lot git-config's custom code
in favor of the regular git_config code.
It does mean we're no longer streaming, and we're storing
more in memory for the --get-all case, but in practice it is
a tiny amount of data, and the results are instantaneous.

The get_value function has a goto label for cleaning up on
errors, but it only cleans up half of what the function
might allocate. Let's also clean up the key and regexp
variables there.
Note that we need to take special care when compiling the
regex fails to clean it up ourselves, since it is in a
half-constructed state (we would want to free it, but not
regfree it).
Similarly, we fix git_config_parse_key to return NULL when
it fails, not a pointer to some already-freed memory.

Teach symbolic-ref to delete symrefs by adding the -d/--delete option to
git-symbolic-ref. Both proper and dangling symrefs are deleted by this
option, but other refs - or anything else that is not a symref - is not.
The symref deletion is performed by first verifying that we are given a
proper symref, and then invoking delete_ref() on it with the REF_NODEREF
flag.

You can currently set the output format to --short or
--porcelain. There is no --long, because we default to it
already. However, you may want to override an alias that
uses "--short" to get back to the default.
This requires a little bit of refactoring, because currently
we use STATUS_FORMAT_LONG internally to mean the same as
"the user did not specify anything". By expanding the enum
to include STATUS_FORMAT_NONE, we can distinguish between
the implicit and explicit cases. This effects these
conditions:
1. The user has asked for NUL termination. With NONE, we
currently default to turning on the porcelain mode.
With an explicit --long, we would in theory use NUL
termination with the long mode, but it does not support
it. So we can just complain and die.
2. When an output format is given to "git commit", we
default to "--dry-run". This behavior would now kick in
when "--long" is given, too.

Before a branch is deleted, we check that it points to a valid
commit. With -d we also check that the commit is a merged; this
check is not done with -D.
The reason for that is that commits pointed to by branches should
never go missing; if they do then something broke and it's better
to stop instead of adding to the mess. And a non-merged commit
may contain changes that are worth preserving, so we require the
stronger option -D instead of -d to get rid of them.
If a branch consists of a symref, these concerns don't apply.
Deleting such a branch can't make a commit become unreferenced,
so we don't need to check if it is merged, or even if it is
actually a valid commit. Skip them in that case. This allows
us to delete dangling symref branches.

This function has only two callsites, and is a thin wrapper whose

5166714 (apply: Allow blank context lines to match beyond EOF,
2010-03-06) and then later 0c3ef98 (apply: Allow blank *trailing*
context lines to match beyond EOF, 2010-04-08) taught "git apply"
to trim new blank lines at the end in the patch text when matching
the contents being patched and the preimage recorded in the patch,
under --whitespace=fix mode.
When a preimage is modified to match the current contents in
preparation for such a "fixed" patch application, the context lines
in the postimage must be updated to match (otherwise, it would
reintroduce whitespace breakages), and update_pre_post_images()
function is responsible for doing this. However, this function was
not updated to take into account a case where the removal of
trailing blank lines reduces the number of lines in the preimage,
and triggered an assertion error.
The logic to fix the postimage by copying the corrected context
lines from the preimage was not prepared to handle this case,
either, but it was protected by the assert() and only got exposed
when the assertion is corrected.

grep searches for .gitattributes using "name" field in struct
grep_source but that field is not real on-disk path name. For example,
"grep pattern rev" fills the field with "rev:path", and Git looks for
.gitattributes in the (non-existent but exploitable) path "rev:path"
instead of "path".
This patch passes real paths down to grep_source_load_driver() when:
- grep on work tree
- grep on the index
- grep a commit (or a tag if it points to a commit)
so that these cases look up .gitattributes at proper paths.
.gitattributes lookup is disabled in all other cases.

The grep_config() function takes one instance of grep_opt as its
callback parameter, and populates it by running git_config().
This has three practical implications:
- You have to have an instance of grep_opt already when you call
the configuration, but that is not necessarily always true. You
may be trying to initialize the grep_filter member of rev_info,
but are not ready to call init_revisions() on it yet.
- It is not easy to enhance grep_config() in such a way to make it
cascade to other callback functions to grab other variables in
one call of git_config(); grep_config() can be cascaded into from
other callbacks, but it has to be at the leaf level of a cascade.
- If you ever need to use more than one instance of grep_opt, you
will have to open and read the configuration file(s) every time
you initialize them.
Rearrange the configuration mechanism and model it after how diff
configuration variables are handled. An early call to git_config()
reads and remembers the values taken from the configuration in the
default "template", and a separate call to grep_init() uses this
template to instantiate a grep_opt.
The next step will be to move some of this out of this file so that
the other user of the grep machinery (i.e. "log") can use it.

The idea of the peel_ref function is to dereference tag
objects recursively until we hit a non-tag, and return the
sha1. Conceptually, it should return 0 if it is successful
(and fill in the sha1), or -1 if there was nothing to peel.
However, the current behavior is much more confusing. For a
regular loose ref, the behavior is as described above. But
there is an optimization to reuse the peeled-ref value for a
ref that came from a packed-refs file. If we have such a
ref, we return its peeled value, even if that peeled value
is null (indicating that we know the ref definitely does
_not_ peel).
It might seem like such information is useful to the caller,
who would then know not to bother loading and trying to peel
the object. Except that they should not bother loading and
trying to peel the object _anyway_, because that fallback is
already handled by peel_ref. In other words, the whole point
of calling this function is that it handles those details
internally, and you either get a sha1, or you know that it
is not peel-able.
This patch catches the null sha1 case internally and
converts it into a -1 return value (i.e., there is nothing
to peel). This simplifies callers, which do not need to
bother checking themselves.
Two callers are worth noting:
- in pack-objects, a comment indicates that there is a
difference between non-peelable tags and unannotated
tags. But that is not the case (before or after this
patch). Whether you get a null sha1 has to do with
internal details of how peel_ref operated.
- in show-ref, if peel_ref returns a failure, the caller
tries to decide whether to try peeling manually based on
whether the REF_ISPACKED flag is set. But this doesn't
make any sense. If the flag is set, that does not
necessarily mean the ref came from a packed-refs file
with the "peeled" extension. But it doesn't matter,
because even if it didn't, there's no point in trying to
peel it ourselves, as peel_ref would already have done
so. In other words, the fallback peeling is guaranteed
to fail.
