Introduce a add_verbose_info function that takes care of adding
- an abbreviated object name;
- a summary of the form [ahead x, behind y] of the relationship
to the corresponding upstream branch;
- a one line commit subject
for the tip commit of a branch, for use in "git branch -v" output.

In a struct definitions, unlike functions, the prevailing style is for
the opening brace to go on the same line as the struct name, like so:
struct foo {
int bar;
char *baz;
};
Indeed, grepping for 'struct [a-z_]* {$' yields about 5 times as many
matches as 'struct [a-z_]*$'.

If enabled on the connection "multi_ack_detailed no-done" as a
pair allows the remote upload-pack process to send a PACK down
to the client as soon as a "ACK %s ready" message was also sent.
Over git:// and ssh:// where a bi-directional stream is in place
this has very little difference over the classical version that
waits for the client to send a "done\n" line by itself. It does
slightly reduce the latency involved to start the pack stream as
there is one less round-trip from client->server required.
Over smart HTTP this avoids needing to send a final RPC that has
all of the prior common objects. Instead the server is able to
return a pack as soon as its ready to. For many common users the
smart HTTP fetch is now just 2 requests: GET .../info/refs, and
a POST .../git-upload-pack to not only negotiate but also receive
the pack stream. Only users who have more than 32 local unshared
commits with the remote will need additional requests to negotiate
a common merge base.

If multi_ack_detailed was selected in the protocol capabilities
(both client and server are >= Git 1.6.6) the upload-pack side will
send "ACK %s ready" when it knows how to safely cut the graph and
produce a reasonable pack for the want list that was already sent
on the connection.
Upon receiving "ACK %s ready" there is no point in looking at
the remaining commits inside of rev_list. Sending additional
"have %s" lines to the remote will not construct a smaller pack.
It is unlikely a commit older than the current cut point will have
a better delta base than the cut point itself has.
The original design of this code had fetch-pack empty rev_list by
marking a commit and its transitive ancestors COMMON whenever the
remote side said "ACK %s {continue,common}" and skipping over any
already COMMON commits during get_rev(). This approach does not
work when most of rev_list is actually COMMON_REF, commits that
are pointed to by a reference on the remote, which exist locally,
and which have not yet been sent to the remote as a "have %s" line.
Most of the common references are tags in the ref/tags namespace,
using points in the commit graph that are more than 1 commit apart.
In git.git itself, this is currently 340 tags, 339 of which point to
commits in the commit graph. fetch-pack pushes all of these into
rev_list, but is unable to mark them COMMON and discard during a
remote's "ACK %s {continue,common}" because it does not parse through
the entire parent chain. Not parsing the entire parent chain is
an optimization to avoid walking back to the roots of the repository.
Assuming the client is only following the remote (and does not make
its own local commits), the client needs 11 rounds to spin through
the entire list of tags (32 commits per round, ceil(339/32) == 11).
Unfortunately the server knows on the first "have %s" line that
it can produce a good pack, and does not need to see the remaining
320 tags in the other 10 rounds.
Over git:// and ssh:// this isn't as bad as it sounds, the client is
only transmitting an extra 16,000 bytes that it doesn't need to send.
Over smart HTTP, the client must do an additional 10 HTTP POST
requests, each of which incurs round-trip latency, and must upload
the entire state vector of all known common objects. On the final
POST request, this is 16 KiB worth of data.
Fix all of this by clearing rev_list as soon as the remote side
says it can construct a pack.

The default of 7 comes from fairly early in git development, when
seven hex digits was a lot (it covers about 250+ million hash
values). Back then I thought that 65k revisions was a lot (it was what
we were about to hit in BK), and each revision tends to be about 5-10
new objects or so, so a million objects was a big number.
These days, the kernel isn't even the largest git project, and even
the kernel has about 220k revisions (_much_ bigger than the BK tree
ever was) and we are approaching two million objects. At that point,
seven hex digits is still unique for a lot of them, but when we're
talking about just two orders of magnitude difference between number
of objects and the hash size, there _will_ be collisions in truncated
hash values. It's no longer even close to unrealistic - it happens all
the time.
We should both increase the default abbrev that was unrealistically
small, _and_ add a way for people to set their own default per-project
in the git config file.
This is the first step to first make it configurable; the default of 7
is not raised yet.

Until now the --recurse-submodules option could only be used to either

To be able to access all commits of populated submodules referenced by the
superproject it is sufficient to only then let "git fetch" recurse into a
submodule when the new commits fetched in the superproject record new
commits for it. Having these commits present is extremely useful when
using the "--submodule" option to "git diff" (which is what "git gui" and
"gitk" do since 1.6.6), as all submodule commits needed for creating a
descriptive output can be accessed. Also merging submodule commits (added
in 1.7.3) depends on the submodule commits in question being present to
work. Last but not least this enables disconnected operation when using
submodules, as all commits necessary for a successful "git submodule
update -N" will have been fetched automatically. So we choose this mode as
the default for fetch and pull.
Before a new or changed ref from upstream is updated in update_local_ref()
"git rev-list <new-sha1> --not --branches --remotes" is used to determine
all newly fetched commits. These are then walked and diffed against their
parent(s) to see if a submodule has been changed. If that is the case, its
path is stored to be fetched after the superproject fetch is completed.
Using the "--recurse-submodules" or the "--no-recurse-submodules" option
disables the examination of the fetched refs because the result will be
ignored anyway.
There is currently no infrastructure for storing deleted and new
submodules in the .git directory of the superproject. That's why fetch and
pull for now only fetch submodules that are already checked out and are
not renamed.
In t7403 the "--no-recurse-submodules" argument had to be added to "git
pull" to avoid failure because of the moved upstream submodule repo.

To keep the code changes simple, we operate at the lowest
level, meaning we don't necessarily understand what's in the
packets. The one exception is a packet starting with "PACK",
which causes us to skip that packet and turn off tracing
(since the gigantic pack data will not be interesting to
read, at least not in the trace format).
We show both written and read packets. In the local case,
this may mean you will see packets twice (written by the
sender and read by the receiver). However, for cases where
the other end is remote, this allows you to see the full

* lt/rename-no-extra-copy-detection:
diffcore-rename: improve estimate_similarity() heuristics
diffcore-rename: properly honor the difference between -M and -C
for_each_hash: allow passing a 'void *data' pointer to callback
When looking for a place to apply a hunk, we used to check lines that
match the preimage of it, starting from the line that the patch wants to
apply the hunk at, looking forward and backward with increasing offsets
until we find a match.
Colin Guthrie found an interesting case where this misapplied a patch that
wanted to touch a preimage that consists of
}
}
return 0;
}
which is a rather unfortunately common pattern.
The target version of the file originally had only one such location, but
the hunk immediately before that created another instance of such block of
lines, and find_pos() happily reported that the preimage of the hunk
matched what it wanted to modify.
Oops.
By marking the lines application of earlier hunks touched and preventing
match_fragment() from considering them as a match with preimage of other
hunks, we can reduce such an accident.
I also considered to teach apply_one_fragment() to take the offset we have
found while applying the previous hunk into account when looking for a
match with find_pos(), but dismissed that approach, because it would
sometimes work better but sometimes worse, depending on the difference
between the version the patch was created against and the version the
patch is being applied.
This does _not_ prevent misapplication of patches to a file that has many
similar looking blocks of lines and a preimage cannot identify which one
of them should be applied. For that, we would need to scan beyond the

A common scenario is to create a new branch and push it (checkout -b &&

Provide the user a command to push the current branch. To avoid the

When "git commit" was rewritten in C (v1.5.4-rc0~78^2~30,

but in the C version the --template parameter gets ignored and
the default template is used.

You can detach the HEAD at an arbitrary commit in order to browse the
files in various points in the history or build older versions of the
software, without recording any new commit, and come back to an existing
branch. When used in this "sightseer" mode, detached HEAD is a perfectly
safe mechanism. It also is a useful state to experiment with throw-away
commits.
When coming back to an existing branch with "git checkout master",
however, the commits that were created on the detached HEAD will become
unreachable from anywhere but the reflog of the HEAD. Check if the commit
we are about to leave is connected to some ref, and give a final warning
otherwise to remind the user for safety.

Sanity-check config variable names when adding and retrieving them. As a side
effect code duplication between git_config_set_multivar and get_value (in
builtin/config.c) was removed and the common functionality was placed in
git_config_parse_key.
This breaks a test in t1300 which used invalid section-less keys in the tests
for "git -c". However, allowing such names there was useless, since there was
no way to set them via config file, and no part of git actually tried to use
section-less keys. This patch updates the test to use more realistic examples
as well as adding its own test.

Previously the user was advised to use commit -c CHERRY_PICK_HEAD after
a conflicting cherry-pick. While this would preserve the original
commit's authorship, it would sadly discard cherry-pick's carefully
crafted MERGE_MSG (which contains the list of conflicts as well as the
original commit-id in the case of cherry-pick -x).
On the other hand, if a bare 'commit' were performed, it would preserve
the MERGE_MSG while resetting the authorship.
In other words, there was no way to simultaneously take the authorship
from CHERRY_PICK_HEAD and the commit message from MERGE_MSG.
This change fixes that situation. A bare 'commit' will now take the
authorship from CHERRY_PICK_HEAD and the commit message from MERGE_MSG.
If the user wishes to reset authorship, that must now be done explicitly
via --reset-author.
A side-benefit of passing commit authorship along this way is that we
can eliminate redundant authorship parsing code from revert.c.

When a cherry-pick conflicts git advises:
$ git commit -c <original commit id>
to preserve the original commit message and authorship. Instead, let's
record the original commit id in CHERRY_PICK_HEAD and advise:
$ git commit -c CHERRY_PICK_HEAD
A later patch teaches git to handle the '-c CHERRY_PICK_HEAD' part.
Note that we record CHERRY_PICK_HEAD even in the case where there
are no conflicts so that we may use it to communicate authorship to
commit; this will then allow us to remove set_author_ident_env from
revert.c. However, we do not record CHERRY_PICK_HEAD when --no-commit
is used, as presumably the user intends to further edit the commit
and possibly even cherry-pick additional commits on top.

After "rerere" resolves conflicts by reusing old resolution, there would
be three kinds of paths with conflict in the index:
* paths that have been resolved in the working tree by rerere;
* paths that need further work whose resolution could be recorded;
* paths that need resolving that rerere won't help.
When the user wants a list of paths that need hand-resolving, output from
"rerere status" does not help, as it shows only the second category, but
the paths in the third category still needs work (rerere only makes sense
for regular files that have both our side and their side, and does not
help other kinds of conflicts, e.g. "we modified, they deleted").
The new subcommand "rerere remaining" can be used to show both. As
opposed to "rerere status", this subcommand also skips printing paths
that have been added to the index, since these paths are already
resolved and are no longer "remaining".
Initial patch provided by Junio. Refactored and modified to skip
resolved paths by Martin. Commit message mostly by Junio.

Users are sometimes confused with two different types of "tracking" behavior
in Git: "remote-tracking" branches (e.g. refs/remotes/*/*) versus the
merge/rebase relationship between a local branch and its @{upstream}
(controlled by branch.foo.remote and branch.foo.merge config settings).
When the push.default is set to 'tracking', it specifies that a branch should
be pushed to its @{upstream} branch. In other words, setting push.default to
'tracking' applies only to the latter of the above two types of "tracking"
behavior.
In order to make this more understandable to the user, we rename the
push.default == 'tracking' option to push.default == 'upstream'.
push.default == 'tracking' is left as a deprecated synonym for 'upstream'.

It is a request to show what _would_ be committed without further "git

The usual dwim_ref lookup prefers tags to branches. Because
checkout primarily works on branches, though, we switch that
behavior to prefer branches.
However, there was a bug in the implementation in which we
used lookup_commit_reference (which used the regular lookup
rules) to get the actual commit to checkout. Checking out an
ambiguous ref therefore ended up putting us in an extremely
broken state in which we wrote the branch ref into HEAD, but
actually checked out the tree for the tag.
This patch fixes the bug by always attempting to pull the
commit to be checked out from the branch-ified version of
the name we were given.

When determine_author_info() returns to the calling prepare_to_commit(),

to fmt_ident() before the final commit_tree(). Most importantly, we would
open the editor to ask the user to compose the log message before it.
As one important side effect of fmt_ident() is to error out when the given
information is malformed, this resulted in us spawning the editor first
and then refusing to commit due to error, even though we had enough
information to detect the error before starting the editor, which was

--refresh and --really-refresh accept flags (like -q) and modify
an error indicator. It might make sense to make the error
indicator global, but just pass the flags and a pointer to the error
indicator in a struct instead.
--cacheinfo wants 3 arguments. Use the OPTION_LOWLEVEL_CALLBACK
extension to grab them and PARSE_OPT_NOARG to disallow the "sticked"
--cacheinfo=foo form. (The resulting message
$ git update-index --cacheinfo=foo
error: option `cacheinfo' takes no value
is unfortunately incorrect.)
--assume-unchanged and --no-assume-unchanged probably should use the
OPT_UYN feature; but use a callback for now so the existing MARK_FLAG
and UNMARK_FLAG values can be used.
--stdin and --index-info are still constrained to be the last argument
(implemented using the OPTION_LOWLEVEL_CALLBACK extension).
--unresolve and --again consume all arguments that come after them
(also using OPTION_LOWLEVEL_CALLBACK).
The order of options matters. Each path on the command line is
affected only by the options that come before it. A custom
argument-parsing loop with parse_options_step() brings that about.
In exchange for all the fuss, we get the usual perks: support for
un-sticked options, better usage error messages, more useful -h
output, and argument parsing code that should be easier to tweak
in the future.

parse_options_check() is being called for each invocation of
parse_options_step which can be quite a bit for some commands. The
commit introducing this function cb9d398 (parse-options: add
parse_options_check to validate option specs., 2009-06-09) had the
correct motivation and explicitly states that parse_options_check()
should be called from parse_options_start(). However, the implementation
differs from the motivation. Fix it.

Teach 'git merge' the --abort option, which verifies the existence of
MERGE_HEAD and then invokes 'git reset --merge' to abort the current
in-progress merge and attempt to reconstruct the pre-merge state.
The reason for adding this option is to provide a user interface for
aborting an in-progress merge that is consistent with the interface
for aborting a rebase ('git rebase --abort'), aborting the application
of a patch series ('git am --abort'), and aborting an in-progress notes
merge ('git notes merge --abort').
The patch includes documentation and testcases that explain and verify
the various scenarios in which 'git merge --abort' can run. The
testcases also document the cases in which 'git merge --abort' is
unable to correctly restore the pre-merge state (look for the '###'
comments towards the bottom of t/t7609-merge-abort.sh).

Reorder the initial part of builtin/merge.c:cmd_merge() so that command-line
options are parsed _before_ we load the index and check for MERGE_HEAD
(and exits if it exists). This does not change the behaviour of 'git merge',

(which requires MERGE_HEAD to be present).

This new strategy is similar to "concatenate", but in addition to
concatenating the two note candidates, this strategy sorts the resulting
lines, and removes duplicate lines from the result. This is equivalent to
applying the "cat | sort | uniq" shell pipeline to the two note candidates.
This strategy is useful if the notes follow a line-based format where one
wants to avoid duplicate lines in the merge result.
Note that if either of the note candidates contain duplicate lines _prior_
to the merge, these will also be removed by this merge strategy.
The patch also contains tests and documentation for the new strategy.

When manually resolving a notes merge, if the merging ref has moved since
the merge started, we should fail to complete the merge, and alert the user
to what's going on.
This situation may arise if you start a 'git notes merge' which results in
conflicts, and you then update the current notes ref (using for example
'git notes add/copy/amend/edit/remove/prune', 'git update-ref', etc.),
before you get around to resolving the notes conflicts and calling
'git notes merge --commit'.
We detect this situation by comparing the first parent of the partial merge
commit (which was created when the merge started) to the current value of the
merging notes ref (pointed to by the .git/NOTES_MERGE_REF symref).
If we don't fail in this situation, the notes merge commit would overwrite
the updated notes ref, thus losing the changes that happened in the meantime.
The patch includes a testcase verifying that we fail correctly in this
situation.

When the notes merge conflicts in .git/NOTES_MERGE_WORKTREE have been
resolved, we need to record a new notes commit on the appropriate notes
ref with the resolved notes.
This patch implements 'git notes merge --commit' which the user should
run after resolving conflicts in the notes merge worktree. This command
finalizes the notes merge by recombining the partial notes tree from
part 1 with the now-resolved conflicts in the notes merge worktree in a
merge commit, and updating the appropriate ref to this merge commit.
In order to correctly finalize the merge, we need to keep track of three
things:
- The partial merge result from part 1, containing the auto-merged notes.
This is now stored into a ref called .git/NOTES_MERGE_PARTIAL.
- The unmerged notes. These are already stored in
.git/NOTES_MERGE_WORKTREE, thanks to part 1.
- The notes ref to be updated by the finalized merge result. This is now
stored in a symref called .git/NOTES_MERGE_REF.
In addition to "git notes merge --commit", which uses the above details
to create the finalized notes merge commit, this patch also implements
"git notes merge --reset", which aborts the ongoing notes merge by simply
removing the files/directory described above.
FTR, "git notes merge --commit" reuses "git notes merge --reset" to remove
the information described above (.git/NOTES_MERGE_*) after the notes merge
have been successfully finalized.
The patch also contains documentation and testcases for the two new options.

Conflicts (that are to be resolved manually) are written into a special-
purpose working tree, located at .git/NOTES_MERGE_WORKTREE. Within this
directory, conflicting notes entries are stored (with conflict markers
produced by ll_merge()) using the SHA1 of the annotated object. The
.git/NOTES_MERGE_WORKTREE directory will only contain the _conflicting_
note entries. The non-conflicting note entries (aka. the partial merge
result) are stored in 'local_tree', and the SHA1 of the resulting commit
is written to 'result_sha1'. The return value from notes_merge() is -1.
The user is told to edit the files within the .git/NOTES_MERGE_WORKTREE
directory in order to resolve the conflicts.
The patch also contains documentation and testcases for the correct setup
of .git/NOTES_MERGE_WORKTREE.
The next part will recombine the partial notes merge result with the
resolved conflicts in .git/NOTES_MERGE_WORKTREE to produce the complete
merge result.

The new -s/--strategy command-line option to 'git notes merge' allow the user
to choose how notes merge conflicts should be resolved. There are four valid
strategies to choose from:
1. "manual" (the default): This will let the user manually resolve conflicts.
This option currently fails with an error message. It will be implemented
properly in future patches.
2. "ours": This automatically chooses the local version of a conflict, and
discards the remote version.
3. "theirs": This automatically chooses the remote version of a conflict, and
discards the local version.
4. "union": This automatically resolves the conflict by appending the remote
version to the local version.
The strategies are implemented using the combine_notes_* functions from the
notes.h API.
The patch also includes testcases verifying the correct implementation of
these strategies.

This continuation of the 'git notes merge' implementation teaches notes-merge
to properly do real merges between notes trees: Two diffs are performed, one
from $base to $remote, and another from $base to $local. The paths in each
diff are normalized to SHA1 object names. The two diffs are then consolidated
into a single list of change pairs to be evaluated. Each change pair consist
of:
- The annotated object's SHA1
- The $base SHA1 (i.e. the common ancestor notes for this object)
- The $local SHA1 (i.e. the current notes for this object)
- The $remote SHA1 (i.e. the to-be-merged notes for this object)
From the pair ($base -> $local, $base -> $remote), we can determine the merge
result using regular 3-way rules. If conflicts are encountered in this
process, we fail loudly and exit (conflict handling to be added in a future
patch), If we can complete the merge without conflicts, the resulting
notes tree is committed, and the current notes ref updated.
The patch includes added testcases verifying that we can successfully do real
conflict-less merges.

The combine_notes_fn functions uses a non-zero return value to indicate
failure. However, this return value was converted to a call to die()
in note_tree_insert().
Instead, propagate this return value out to add_note(), and return it
from there to enable the caller to handle errors appropriately.
Existing add_note() callers are updated to die() upon failure, thus
preserving the current behaviour. The only exceptions are copy_note()
and notes_cache_put() where we are able to propagate the add_note()
return value instead.
