Commit 38a4556 (index-pack: start learning to emulate
"verify-pack -v", 2011-06-03) added a "delta_depth" counter
to each "struct object_entry". Initially, all object entries
have their depth set to 0; in resolve_delta, we then set the
depth of each delta to "base + 1". Base entries never have
their depth touched, and remain at 0.
To ensure that all depths start at 0, that commit changed
calls to xmalloc the object_entry list into calls to
xcalloc. However, it forgot that we grow the list with
xrealloc later. These extra entries are used when we add an
object from elsewhere to complete a thin pack. If we add a
non-delta object, its depth value will just be uninitialized
heap data.
This patch fixes it by zero-initializing entries we add to
the objects list via the xrealloc.

The threaded parts of index-pack increment the number of resolved
deltas in nr_resolved_deltas guarded by counter_mutex. However, the
per-thread outer loop accessed nr_resolved_deltas without any locks.
This is not wrong as such, since it doesn't matter all that much
whether we get an outdated value. However, unless someone proves that
this one lock makes all the performance difference, it would be much
cleaner to guard _all_ accesses to the variable with the lock.
The only such use is display_progress() in the threaded section (all
others are in the conclude_pack() callchain outside the threaded
part). To make it obvious that it cannot deadlock, move it out of
work_mutex.

deepest_delta is a global variable but is updated without protection

Another variable that will not be updated is delta_depth in "struct

"if (show_stat)" makes it clearer.
The local variable "stat" is renamed to "show_stat" after moving to

When fast-export wants to export a blob object, it first
calls parse_object to get a "struct object" and check
whether we have already shown the object. If we haven't
shown it, we then use read_sha1_file to pull it from disk
and write it out.
That means we load each blob from disk twice: once for
parse_object to find its type and check its sha1, and a
second time when we actually output it. We can drop this to
a single load by using lookup_object to check the SHOWN
flag, and then checking the signature on and outputting a
single buffer.
This provides modest speedups on git.git (best-of-five, "git

When "git add subdir/" is run without "-u" or "-A" option, e.g.
$ edit subdir/x
$ create subdir/y
$ rm subdir/z
$ git add subdir/
the command does not notice removal of paths (e.g. subdir/z) from
the working tree. This sometimes confuses new people, as arguably
"git add" is told to record the current state of "subdir/" as a
whole, not the current state of the paths that exist in the working
tree that matches that pathspec (the latter by definition excludes
the state of "subdir/z" because it does not exist in the working
tree).
Plan to eventually make "git add" pretend as if "-A" is given when
there is a pathspec on the command line. When resolving a conflict
to remove a path, the current code tells you to "git rm $path", but
with such a change, you will be able to say "git add $path" (of
course you can do "git add -A $path" today). That means that we can
simplify the advice messages given by "git status". That all will
be in Git 2.0 or later, if we are going to do so.
For that transition to work, people need to learn either to say "git
add --no-all subdir/" when they want to ignore the removed paths
like "subdir/z", or to say "git add -A subdir/" when they want to
take the state of the directory as a whole.
"git add" without any argument will continue to be a no-op.

A maildir does not technically record the order in which
items were placed into it. That means that when applying a
patch series from a maildir, we may get the patches in the
wrong order. We try to work around this by sorting the
filenames. Unfortunately, this may or may not work depending
on the naming scheme used by the writer of the maildir.
For instance, mutt will write:
${epoch_seconds}.${pid}_${seq}.${host}
where we have:
- epoch_seconds: timestamp at which entry was written
- pid: PID of writing process
- seq: a sequence number to ensure uniqueness of filenames
- host: hostname
None of the numbers are zero-padded. Therefore, when we sort
the names as byte strings, entries that cross a digit
boundary (e.g., 10) will sort out of order. In the case of
timestamps, it almost never matters (because we do not cross
a digit boundary in the epoch time very often these days).
But for the sequence number, a 10-patch series would be
ordered as 1, 10, 2, 3, etc.
To fix this, we can use a custom sort comparison function
which traverses each string, comparing chunks of digits
numerically, and otherwise doing a byte-for-byte comparison.
That would sort:
123.456_1.bar
123.456_2.bar
...
123.456_10.bar
according to the sequence number. Since maildir does not
define a filename format, this is really just a heuristic.
But it happens to work for mutt, and there is a reasonable
chance that it will work for other writers, too (at least as
well as a straight sort).

Most of the callers of packet_read_line just read into a
static 1000-byte buffer (callers which handle arbitrary
binary data already use LARGE_PACKET_MAX). This works fine
in practice, because:
1. The only variable-sized data in these lines is a ref
name, and refs tend to be a lot shorter than 1000
characters.
2. When sending ref lines, git-core always limits itself
to 1000 byte packets.
However, the only limit given in the protocol specification
in Documentation/technical/protocol-common.txt is
LARGE_PACKET_MAX; the 1000 byte limit is mentioned only in
pack-protocol.txt, and then only describing what we write,
not as a specific limit for readers.
This patch lets us bump the 1000-byte limit to
LARGE_PACKET_MAX. Even though git-core will never write a
packet where this makes a difference, there are two good
reasons to do this:
1. Other git implementations may have followed
protocol-common.txt and used a larger maximum size. We
don't bump into it in practice because it would involve
very long ref names.
2. We may want to increase the 1000-byte limit one day.
Since packets are transferred before any capabilities,
it's difficult to do this in a backwards-compatible
way. But if we bump the size of buffer the readers can
handle, eventually older versions of git will be
obsolete enough that we can justify bumping the
writers, as well. We don't have plans to do this
anytime soon, but there is no reason not to start the
clock ticking now.
Just bumping all of the reading bufs to LARGE_PACKET_MAX
would waste memory. Instead, since most readers just read
into a temporary buffer anyway, let's provide a single
static buffer that all callers can use. We can further wrap
this detail away by having the packet_read_line wrapper just
use the buffer transparently and return a pointer to the
static storage. That covers most of the cases, and the
remaining ones already read into their own LARGE_PACKET_MAX
buffers.

The packets sent during ref negotiation are all terminated
by newline; even though the code to chomp these newlines is
short, we end up doing it in a lot of places.
This patch teaches packet_read_line to auto-chomp the
trailing newline; this lets us get rid of a lot of inline
chomping code.
As a result, some call-sites which are not reading
line-oriented data (e.g., when reading chunks of packfiles
alongside sideband) transition away from packet_read_line to
the generic packet_read interface. This patch converts all
of the existing callsites.
Since the function signature of packet_read_line does not
change (but its behavior does), there is a possibility of
new callsites being introduced in later commits, silently
introducing an incompatibility. However, since a later
patch in this series will change the signature, such a
commit would have to be merged directly into this commit,
not to the tip of the series; we can therefore ignore the
issue.
This is an internal cleanup and should produce no change of
behavior in the normal case. However, there is one corner
case to note. Callers of packet_read_line have never been
able to tell the difference between a flush packet ("0000")
and an empty packet ("0004"), as both cause packet_read_line
to return a length of 0. Readers treat them identically,
even though Documentation/technical/protocol-common.txt says
we must not; it also says that implementations should not
send an empty pkt-line.
By stripping out the newline before the result gets to the
caller, we will now treat the newline-only packet ("0005\n")
the same as an empty packet, which in turn gets treated like
a flush packet. In practice this doesn't matter, as neither
empty nor newline-only packets are part of git's protocols
(at least not for the line-oriented bits, and readers who
are not expecting line-oriented packets will be calling
packet_read directly, anyway). But even if we do decide to
care about the distinction later, it is orthogonal to this
patch. The right place to tighten would be to stop treating
empty packets as flush packets, and this change does not
make doing so any harder.

The current parsing scheme for upload-archive is to pack
arguments into a fixed-size buffer, separated by NULs, and
put a pointer to each argument in the buffer into a
fixed-size argv array.
This works fine, and the limits are high enough that nobody
reasonable is going to hit them, but it makes the code hard
to follow. Instead, let's just stuff the arguments into an
argv_array, which is much simpler. That lifts the "all
arguments must fit inside 4K together" limit.
We could also trivially lift the MAX_ARGS limitation (in
fact, we have to keep extra code to enforce it). But that
would mean a client could force us to allocate an arbitrary
amount of memory simply by sending us "argument" lines. By
limiting the MAX_ARGS, we limit an attacker to about 4
megabytes (64 times a maximum 64K packet buffer). That may
sound like a lot compared to the 4K limit, but it's not a
big deal compared to what git-archive will actually allocate
while working (e.g., to load blobs into memory). The
important thing is that it is bounded.

because we almost always ask for hash values for a path that is a
candidate to be added to the index. However, check-ignore (and most
likely check-attr, but I didn't check) apparently has a callchain
to ask the hash value for an empty path when it was given a "." from

Make sure that hash_name() does not overrun the end of the given
pathname even when it is empty.
Remove a sweep-the-issue-under-the-rug conditional in check-ignore

It is a valid question to ask for check-ignore if the top-level is
set to be ignored by default, even though the answer is most likely
no, if only because there is currently no way to specify such an

A repository may have refs that are only used for its internal

by paying attention to the uploadpack.hiderefs multi-valued
configuration variable. Do the same to receive-pack via the

transfer.hiderefs to set the value to both of these variables.
Any ref that is under the hierarchies listed on the value of these
variable is excluded from responses to requests made by "ls-remote",
"fetch", etc. (for upload-pack) and "push" (for receive-pack).
Because these hidden refs do not count as OUR_REF, an attempt to
fetch objects at the tip of them will be rejected, and because these
refs do not get advertised, "git push :" will not see local branches
that have the same name as them as "matching" ones to be sent.
An attempt to update/delete these hidden refs with an explicit
refspec, e.g. "git push origin :refs/hidden/22", is rejected. This
is not a new restriction. To the pusher, it would appear that there
is no such ref, so its push request will conclude with "Now that I
sent you all the data, it is time for you to update the refs. I saw
that the ref did not exist when I started pushing, and I want the
result to point at this commit". The receiving end will apply the
compare-and-swap rule to this request and rejects the push with
"Well, your update request conflicts with somebody else; I see there
is such a ref.", which is the right thing to do. Otherwise a push to
a hidden ref will always be "the last one wins", which is not a good

"git am -3" uses this function to build a tree that records how the
preimage the patch was created from would have looked like. An
abbreviated object name on the index line is ordinarily sufficient
for us to figure out the object name the preimage tree would have
contained, but a change to a submodule by definition shows an object
name of a submodule commit which our repository should not have, and
get_sha1_blob() is not an appropriate way to read it (or get_sha1()
for that matter).
Use get_sha1_hex() and complain if we do not find a full object name
there.
We could read from the payload part of the patch to learn the full
object name of the commit, but the primary user "git rebase" has
been fixed to give us a full object name, so this should suffice
for now.

Currently, a branch filter like `--contains`, `--merged`, or
`--no-merged` is ignored when we are not in listing mode.
For example:
git branch --contains=foo bar
will create the branch "bar" from the current HEAD, ignoring
the `--contains` argument entirely. This is not very
helpful. There are two reasonable behaviors for git here:
1. Flag an error; the arguments do not make sense.
2. Implicitly go into `--list` mode
This patch chooses the latter, as it is more convenient, and
there should not be any ambiguity with attempting to create
a branch; using `--contains` and not wanting to list is
nonsensical.
That leaves the case where an explicit modification option
like `-d` is given. We already catch the case where
`--list` is given alongside `-d` and flag an error. With
this patch, we will also catch the use of `--contains` and
other filter options alongside `-d`.

Most Git commands that can be used with or without pathspec operate
tree-wide by default, the pathspec being used to restrict their
scope. A few exceptions are: 'git grep', 'git clean', 'git add -u'
and 'git add -A'. When run in a subdirectory without pathspec, they
operate only on paths in the current directory.
The inconsistency of 'git add -u' and 'git add -A' is particularly
problematic since other 'git add' subcommands (namely 'git add -p'
and 'git add -e') are tree-wide by default. It also means that "git
add -u && git commit" will record a state that is different from
what is recorded with "git commit -a".
Flipping the default now is unacceptable, so let's start training
users to type 'git add -u|-A :/' or 'git add -u|-A .' explicitly, to
prepare for the next steps:
* forbid 'git add -u|-A' without pathspec (like 'git add' without
option)
* much later, maybe, re-allow 'git add -u|-A' without pathspec, that
will add all tracked and modified files, or all files, tree-wide.
A nice side effect of this patch is that it makes the :/ magic
pathspec easier to discover for users.
When the command is called from the root of the tree, there is no
ambiguity and no need to change the behavior, hence no need to warn.

When we look up a sha1 object for reading via parse_object() =>
read_sha1_file() => read_object() callpath, we first check
packfiles, and then loose objects. If we still haven't found it, we
re-scan the list of packfiles in `objects/pack`. This final step
ensures that we can co-exist with a simultaneous repack process
which creates a new pack and then prunes the old object.
This extra re-scan usually does not have a performance impact for
two reasons:
1. If an object is missing, then typically the re-scan will find a
new pack, then no more misses will occur. Or if it truly is
missing, then our next step is usually to die().
2. Re-scanning is cheap enough that we do not even notice.
However, these do not always hold. The assumption in (1) is that the
caller is expecting to find the object. This is usually the case,
but the call to `parse_object` in `everything_local` does not follow
this pattern. It is looking to see whether we have objects that the
remote side is advertising, not something we expect to
have. Therefore if we are fetching from a remote which has many refs
pointing to objects we do not have, we may end up re-scanning the
pack directory many times.
Even with this extra re-scanning, the impact is often not noticeable
due to (2); we just readdir() the packs directory and skip any packs
that are already loaded. However, if there are a large number of
packs, even enumerating the directory can be expensive, especially
if we do it repeatedly.
Having this many packs is a good sign the user should run `git gc`,
but it would still be nice to avoid having to scan the directory at
all.

We generally try to run "gc --auto" after any commands that
might introduce a large number of new objects. An obvious
place to do so is after running "fetch", which may introduce
new loose objects or packs (depending on the size of the
fetch).
While an active developer repository will probably
eventually trigger a "gc --auto" on another action (e.g.,
git-rebase), there are two good reasons why it is nicer to
do it at fetch time:
1. Read-only repositories which track an upstream (e.g., a
continuous integration server which fetches and builds,
but never makes new commits) will accrue loose objects
and small packs, but never coalesce them into a more
efficient larger pack.
2. Fetching is often already perceived to be slow to the
user, since they have to wait on the network. It's much
more pleasant to include a potentially slow auto-gc as
part of the already-long network fetch than in the
middle of productive work with git-rebase or similar.

Usually a commit that makes it to logmsg_reencode will have
been parsed, and the commit->buffer struct member will be
valid. However, some code paths will free commit buffers
after having used them (for example, the log traversal
machinery will do so to keep memory usage down).
Most of the time this is fine; log should only show a commit
once, and then exits. However, there are some code paths
where this does not work. At least two are known:
1. A commit may be shown as part of a regular ref, and
then it may be shown again as part of a submodule diff
(e.g., if a repo contains refs to both the superproject
and subproject).
2. A notes-cache commit may be shown during "log --all",
and then later used to access a textconv cache during a
diff.
Lazily loading in logmsg_reencode does not necessarily catch
all such cases, but it should catch most of them. Users of
the commit buffer tend to be either parsing for structure
(in which they will call parse_commit, and either we will
already have parsed, or we will load commit->buffer lazily
there), or outputting (either to the user, or fetching a
part of the commit message via format_commit_message). In
the latter case, we should always be using logmsg_reencode
anyway (and typically we do so via the pretty-print
machinery).
If there are any cases that this misses, we can fix them up
to use logmsg_reencode (or handle them on a case-by-case
basis if that is inappropriate).

The logmsg_reencode function will return the reencoded
commit buffer, or NULL if reencoding failed or no reencoding
was necessary. Since every caller then ends up checking for NULL
and just using the commit's original buffer, anyway, we can
be a bit more helpful and just return that buffer when we
would have returned NULL.
Since the resulting string may or may not need to be freed,
we introduce a logmsg_free, which checks whether the buffer
came from the commit object or not (callers either
implemented the same check already, or kept two separate
pointers, one to mark the buffer to be used, and one for the
to-be-freed string).
Pushing this logic into logmsg_* simplifies the callers, and
will let future patches lazily load the commit buffer in a
single place.

When git-commit is asked to reuse a commit message via "-c",
we call read_commit_message, which looks up the commit and
hands back either the re-encoded result, or a copy of the
original. We make a copy in the latter case so that the
ownership semantics of the return value are clear (in either
case, it can be freed).
However, since we return a "const char *", and since the
resulting buffer's lifetime is the same as that of the whole
program, we never bother to free it at all.
Let's just drop the copy. That saves us a copy in the common
case. While it does mean we leak in the re-encode case, it
doesn't matter, since we are relying on program exit to free
the memory anyway.

Now that "already exists" errors are given only when a push tries to

When we push to update an existing ref, if:
* the object at the tip of the remote is not a commit; or
* the object we are pushing is not a commit,
it won't be correct to suggest to fetch, integrate and push again,
as the old and new objects will not "merge". We should explain that
the push must be forced when there is a non-committish object is
involved in such a case.
If we do not have the current object at the tip of the remote, we do
not even know that object, when fetched, is something that can be
merged. In such a case, suggesting to pull first just like
non-fast-forward case may not be technically correct, but in
practice, most such failures are seen when you try to push your work
to a branch without knowing that somebody else already pushed to
update the same branch since you forked, so "pull first" would work
as a suggestion most of the time. And if the object at the tip is
not a commit, "pull first" will fail, without making any permanent
damage. As a side effect, it also makes the error message the user
will get during the next "push" attempt easier to understand, now
the user is aware that a non-commit object is involved.
In these cases, the current code already rejects such a push on the
client end, but we used the same error and advice messages as the
ones used when rejecting a non-fast-forward push, i.e. pull from
there and integrate before pushing again.
Introduce new rejection reasons and reword the messages
appropriately.

Thanks to b65982b (Optimize "diff-index --cached" using cache-tree,

user type the trailing " ." to get the faster do_diff_cache()-based
implementation, always use it when doing a mixed reset, with or

Timing "git reset" shows that it indeed becomes as fast as

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

The sha1 is only passed to read_from_tree(), which already only

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.

"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
linux-2.6 repo (best of five, warm cache):

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
interactive_reset() and read_from_tree(). Both of these call
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
the (arguably clearer) "if (pathspec)" in place of "if (i < argc)".

"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
work tree. Now only the ambiguous one fails.

There are two paths to update_index_refresh() from cmd_reset(), but on

(although practically free).

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
duplicate the return value themselves.

(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.

Since b57fb80a7d (init, clone: support --separate-git-dir for .git file)
git clone supports the --separate-git-dir option to create the git dir
outside the work tree. But when that option is used, the git dir won't be
deleted in case the clone fails like it would be without this option. This
makes clone lose its atomicity as in case of a failure a partly set up git
dir is left behind. A real world example where this leads to problems is
when "git submodule update" fails to clone a submodule and later calls to
"git submodule update" stumble over the partially set up git dir and try
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

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
the patches belonging to the second iteration easily.

A recent commit [1] fixed a off-by-one wrapping error. As a

whether to append a newline needs to be removed. The function
should always append a newline, which was the case before the
off-by-one fix, because strbuf_add_wrapped_text() never returns a
value of wraplen; when it returns wraplen, the string does not end
with a newline, so this caller needs to add one anyway.

Various codepaths checked if two encoding names are the same using
ad-hoc code and some of them ended up asking iconv() to convert

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.
Signed-off-by: Jeff King <peff@peff.net>
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.

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.

When a preimage is modified to match the current contents in

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.

Currently "git am" does insane things if the mbox it is given contains
attachments with a MIME type that aren't "text/*".
In particular, it will still decode them, and pass them "one line at a
time" to the mail body filter, but because it has determined that they
aren't text (without actually looking at the contents, just at the mime
type) the "line" will be the encoding line (eg 'base64') rather than a
line of *content*.
Which then will cause the text filtering to fail, because we won't
correctly notice when the attachment text switches from the commit message
to the actual patch. Resulting in a patch failure, even if patch may be a
perfectly well-formed attachment, it's just that the message type may be
(for example) "application/octet-stream" instead of "text/plain".
Just remove all the bogus games with the message_type. The only difference
that code creates is how the data is passed to the filter function
(chunked per-pred-code line or per post-decode line), and that difference
is *wrong*, since chunking things per pre-decode line can never be a
sensible operation, and cannot possibly matter for binary data anyway.
This code goes all the way back to March of 2007, in commit 87ab799234
("builtin-mailinfo.c infrastrcture changes"), and apparently Don used to
pass random mbox contents to git. However, the pre-decode vs post-decode
logic really shouldn't matter even for that case, and more importantly, "I
fed git am crap" is not a valid reason to break *real* patch attachments.
If somebody really cares, and determines that some attachment is binary
data (by looking at the data, not the MIME-type), the whole attachment
should be dismissed, rather than fed in random-sized chunks to
"handle_filter()".

Currently using "git rm" on a submodule - populated or not - fails with
this error:
fatal: git rm: '<submodule path>': Is a directory
This made sense in the past as there was no way to remove a submodule
without possibly removing unpushed parts of the submodule's history
contained in its .git directory too, so erroring out here protected the
user from possible loss of data.
But submodules cloned with a recent git version do not contain the .git
directory anymore, they use a gitfile to point to their git directory
which is safely stored inside the superproject's .git directory. The work
tree of these submodules can safely be removed without losing history, so
let's teach git to do so.
Using rm on an unpopulated submodule now removes the empty directory from
the work tree and the gitlink from the index. If the submodule's directory
is missing from the work tree, it will still be removed from the index.
Using rm on a populated submodule using a gitfile will apply the usual
checks for work tree modification adapted to submodules (unless forced).
For a submodule that means that the HEAD is the same as recorded in the
index, no tracked files are modified and no untracked files that aren't
ignored are present in the submodules work tree (ignored files are deemed
expendable and won't stop a submodule's work tree from being removed).
That logic has to be applied in all nested submodules too.
Using rm on a submodule which has its .git directory inside the work trees
top level directory will just error out like it did before to protect the
repository, even when forced. In the future git could either provide a
message informing the user to convert the submodule to use a gitfile or
even attempt to do the conversion itself, but that is not part of this
change.

Receive-pack invokes either unpack-objects or index-pack to
handle the incoming pack. However, we do not redirect the
stderr of the sub-processes at all, so it is never seen by
the client. From the initial thread adding sideband support,
which is here:
http://thread.gmane.org/gmane.comp.version-control.git/139471
it is clear that some messages are specifically kept off the
sideband (with the assumption that they are of interest only
to an administrator, not the client). The stderr of the
subprocesses is mentioned in the thread, but it's unclear if
they are included in that group, or were simply forgotten.
However, there are a few good reasons to show them to the
client:
1. In many cases, they are directly about the incoming
packfile (e.g., fsck warnings with --strict, corruption
in the packfile, etc). Without these messages, the
client just gets "unpacker error" with no extra useful
diagnosis.
2. No matter what the cause, we are probably better off
showing the errors to the client. If the client and the
server admin are not the same entity, it is probably
much easier for the client to cut-and-paste the errors
they see than for the admin to try to dig them out of a
log and correlate them with a particular session.
3. Users of the ssh transport typically already see these
stderr messages, as the remote's stderr is copied
literally by ssh. This brings other transports (http,
and push-over-git if you are crazy enough to enable it)
more in line with ssh. As a bonus for ssh users,
because the messages are now fed through the sideband
and printed by the local git, they will have "remote:"
prepended and be properly interleaved with any local
output to stderr.

"Content-type: text/plain; charset=UTF-8" header should not appear
twice in the input, but it is always better to gracefully deal with
such a case. The current code concatenates the value to the values
we have seen previously, producing nonsense such as "utf8UTF-8".
Instead of concatenating, forget the previous value and use the last

Our "grep" allows complex boolean expressions to be formed to match
each individual line with operators like --and, '(', ')' and --not.
Introduce the "--debug" option to show the parse tree to help people
who want to debug and enhance it.
Also "log" learns "--grep-debug" option to do the same. The command
line parser to the log family is a lot more limited than the general
"git grep" parser, but it has special handling for header matching
(e.g. "--author"), and a parse tree is valuable when working on it.
Note that "--all-match" is *not* any individual node in the parse
tree. It is an instruction to the evaluator to check all the nodes
in the top-level backbone have matched and reject a document as
non-matching otherwise.

"git blame file" has always meant "find the origin of each line of
the file in the history leading to HEAD, oh by the way, blame the
lines that are modified locally to the working tree".
This teaches "git blame" that during a conflicted merge, some
uncommitted changes may have come from the other history that is
being merged.
The verify_working_tree_path() function introduced in the previous
patch to notice a typo in the filename (primarily on case insensitive
filesystems) has been updated to allow a filename that does not exist
in HEAD (i.e. the tip of our history) as long as it exists one of the
commits being merged, so that a "we deleted, the other side modified"
case tracks the history of the file in the history of the other side.

checkout operates in three different modes. On top of that it tries to
be smart by guessing the branch name for switching. This results in
messy option handling code. This patch reorders it so that
- cmd_checkout() is responsible for parsing, preparing input and
determining mode
- Code of each mode is in checkout_paths() and checkout_branch(),
where sanity checks are performed
Another slight improvement is always print branch name (or commit
name) when printing errors related ot them. This helps catch the case
where an option is mistaken as branch/commit.

"git blame MAKEFILE" run in a history that has "Makefile" but not
MAKEFILE can get confused on a case insensitive filesystem, because
the check we run to see if there is a corresponding file in the
working tree with lstat("MAKEFILE") succeeds. In addition to that
check, we have to make sure that the given path also exists in the
commit we start digging history from (i.e. "HEAD").
Note that this reveals the breakage in a test added in cd8ae20
(git-blame shouldn't crash if run in an unmerged tree, 2007-10-18),
which expects the entire merge-in-progress path to be blamed to the
working tree when it did not exist in our tree. As it is clear in
the log message of that commit, the old breakage was that it was
causing an internal error and the fix was about avoiding it.
Just check that the command does not die an uncontrolled death. For

fetch_populated_submodules() allocates the full argv array it uses to

replaced with those currently valid.

When giving multiple individual revisions to cherry-pick or revert, as
in 'git cherry-pick A B' or 'git revert B A', one would expect them to
be picked/reverted in the order given on the command line. They are
instead ordered by their commit timestamp -- in chronological order
for "cherry-pick" and in reverse chronological order for
"revert". This matches the order in which one would usually give them
on the command line, making this bug somewhat hard to notice. Still,
it has been reported at least once before [1].
It seems like the chronological sorting happened by accident because
the revision walker has traditionally always sorted commits in reverse
chronological order when rev_info.no_walk was enabled. In the case of
'git revert B A' where B is newer than A, this sorting is a no-op. For
'git cherry-pick A B', the sorting would reverse the arguments, but
because the sequencer also flips the rev_info.reverse flag when
picking (as opposed to reverting), the end result is a chronological
order. The rev_info.reverse flag was probably flipped so that the
revision walker emits B before C in 'git cherry-pick A..C'; that it
happened to effectively undo the unexpected sorting done when not
walking, was probably a coincidence that allowed this bug to happen at
all.
Fix the bug by telling the revision walker not to sort the commits
when not walking. The only case we want to reverse the order is now
when cherry-picking and walking revisions (rev_info.no_walk = 0).

When 'git log' is passed the --no-walk option, no revision walk takes
place, naturally. Perhaps somewhat surprisingly, however, the provided
revisions still get sorted by commit date. So e.g 'git log --no-walk
HEAD HEAD~1' and 'git log --no-walk HEAD~1 HEAD' give the same result
(unless the two revisions share the commit date, in which case they
will retain the order given on the command line). As the commit that
introduced --no-walk (8e64006 (Teach revision machinery about
--no-walk, 2007-07-24)) points out, the sorting is intentional, to
allow things like
git log --abbrev-commit --pretty=oneline --decorate --all --no-walk
to show all refs in order by commit date.
But there are also other cases where the sorting is not wanted, such
as
<command producing revisions in order> |
git log --oneline --no-walk --stdin
To accomodate both cases, leave the decision of whether or not to sort
up to the caller, by allowing --no-walk={sorted,unsorted}, defaulting
to 'sorted' for backward-compatibility reasons.

Originally the "--quiet" option was parsed by the
diff-option parser into the internal QUICK option. This had
the effect of silencing diff output from the log (which was
not intended, but happened to work and people started to
use it). But it also had other odd side effects at the diff
level (for example, it would suppress the second commit in
"git show A B").
To fix this, commit 1c40c36 converted log to parse-options
and handled the "quiet" option separately, not passing it
on to the diff code. However, it simply ignored the option,
which was a regression for people using it as a synonym for
"-s". Commit 01771a8 then fixed that by interpreting the
option to add DIFF_FORMAT_NO_OUTPUT to the list of output
formats.
However, that commit did not fix it in all cases. It sets
the flag after setup_revisions is called. Naively, this
makes sense because you would expect the setup_revisions
parser to overwrite our output format flag if "-p" or
another output format flag is seen.
However, that is not how the NO_OUTPUT flag works. We
actually store it in the bit-field as just another format.
At the end of setup_revisions, we call diff_setup_done,
which post-processes the bitfield and clears any other
formats if we have set NO_OUTPUT. By setting the flag after
setup_revisions is done, diff_setup_done does not have a
chance to make this tweak, and we end up with other format
options still set.
As a result, the flag would have no effect in "git log -p
--quiet" or "git show --quiet". Fix it by setting the
format flag before the call to setup_revisions.

Branch names are usually in ASCII so they are not the problem. The
problem most likely comes from "(no branch)" translation, which is
in UTF-8 and makes display-width calculation just wrong. Clarify
this by renaming the field "len" in struct ref_item to "width", as
it stores the display-width and is used to compute the width of the
screen needed to show the names of all the branches, and compute the
display width using utf8_strwidth(), not byte-length with strlen().
Update document to mention the fact that we may want ref names in
UTF-8. Encodings that produce invalid UTF-8 are safe as utf8_strwidth()
falls back to strlen(). The ones that incidentally produce valid UTF-8
sequences will cause misalignment.

Back when "git apply" was written, we made sure that the user can
skip more than the default number of path components (i.e. 1) by
giving "-p<n>", but the logic for doing so was built around the
notion of "we skip N slashes and stop". This obviously does not
work well when running under -p0 where we do not want to skip any,
but still want to skip SP/HT that separates the pathnames of
preimage and postimage and want to reject absolute pathnames.
Stop using "stop_at_slash()", and instead introduce a new helper
"skip_tree_prefix()" with similar logic but works correctly even for
the -p0 case.
This is an ancient bug, but has been masked for a long time because
most of the patches are text and have other clues to tell us the
name of the preimage and the postimage.

The existing --set-uptream option can cause confusion, as it uses the
usual branch convention of assuming a starting point of HEAD if none
is specified, causing
git branch --set-upstream origin/master
to create a new local branch 'origin/master' that tracks the current
branch. As --set-upstream already exists, we can't simply change its
behaviour. To work around this, introduce --set-upstream-to which
accepts a compulsory argument indicating what the new upstream branch
should be and one optinal argument indicating which branch to change,
defaulting to HEAD.
The new options allows us to type

Commit ff5effdf taught both clients and servers of the git protocol
to send an "agent" capability that just advertises their version for
statistics and debugging purposes. The protocol-capabilities.txt
document however indicates that the client's advertisement is
actually a response, and should never include capabilities not
mentioned in the server's advertisement.
Adding the unconditional advertisement in the server programs was
OK, then, but the clients broke the protocol. The server
implementation of git-core itself does not care, but at least one
does: the Google Code git server (or any server using Dulwich), will
hang up with an internal error upon seeing an unknown capability.
Instead, each client must record whether we saw an agent string from
the server, and respond with its agent only if the server mentioned
it first.

If we have capabilities to send to the server, we send the
regular "want" line followed by a NUL, then the
capabilities; otherwise, we do not even send the NUL.
However, when checking whether we want to send the "quiet"
capability, we check args->quiet, which is wrong. That flag
only tells us whether the client side wanted to be quiet,
not whether the server supports it (originally, in c207e34f,
it meant both; however, that was later split into two flags
by 01fdc21f).
We still check the right flag when actually printing
"quiet", so this could only have two effects:
1. We might send the trailing NUL when we do not otherwise
need to. In theory, an antique pre-capability
implementation of git might choke on this (since the
client is instructed never to respond with capabilities
that the server has not first advertised).
2. We might also want to send the quiet flag if the
args->progress flag is false, but this code path would
not trigger in that instance.
In practice, it almost certainly never matters. The
report-status capability dates back to 2005. Any real-world
server is going to advertise that, and we will always
respond with at least that capability.

Removing an unnecessary loose object file, on the other hand, is

Instead of having the client advertise a particular version
number in the git protocol, we have managed extensions and
backwards compatibility by having clients and servers
advertise capabilities that they support. This is far more
robust than having each side consult a table of
known versions, and provides sufficient information for the
protocol interaction to complete.
However, it does not allow servers to keep statistics on
which client versions are being used. This information is
not necessary to complete the network request (the
capabilities provide enough information for that), but it
may be helpful to conduct a general survey of client
versions in use.
We already send the client version in the user-agent header
for http requests; adding it here allows us to gather
similar statistics for non-http requests.

The diff code represents paths using the diff_filespec
struct. This struct has a sha1 to represent the sha1 of the
content at that path, as well as a sha1_valid member which
indicates whether its sha1 field is actually useful. If
sha1_valid is not true, then the filespec represents a
working tree file (e.g., for the no-index case, or for when
the index is not up-to-date).
The diff_filespec is only used internally, though. At the
interfaces to the diff subsystem, callers feed the sha1
directly, and we create a diff_filespec from it. It's at
that point that we look at the sha1 and decide whether it is
valid or not; callers may pass the null sha1 as a sentinel
value to indicate that it is not.
We should not typically see the null sha1 coming from any
other source (e.g., in the index itself, or from a tree).
However, a corrupt tree might have a null sha1, which would
cause "diff --patch" to accidentally diff the working tree
version of a file instead of treating it as a blob.
This patch extends the edges of the diff interface to accept
a "sha1_valid" flag whenever we accept a sha1, and to use
that flag when creating a filespec. In some cases, this
means passing the flag through several layers, making the
code change larger than would be desirable.
One alternative would be to simply die() upon seeing
corrupted trees with null sha1s. However, this fix more
directly addresses the problem (while bogus sha1s in a tree
are probably a bad thing, it is really the sentinel
confusion sending us down the wrong code path that is what
makes it devastating). And it means that git is more capable
of examining and debugging these corrupted trees. For
example, you can still "diff --raw" such a tree to find out
when the bogus entry was introduced; you just cannot do a
"--patch" diff (just as you could not with any other
corrupted tree, as we do not have any content to diff).

incorrectly computed reachability of the detached HEAD, resulting in

* jk/maint-checkout-orphan-check-fix:
checkout: don't confuse ref and object flags
When we are leaving a detached HEAD, we do a revision traversal to
check whether we are orphaning any commits, marking the commit we're
leaving as the start of the traversal, and all existing refs as
uninteresting.
Prior to commit 468224e5, we did so by calling for_each_ref, and
feeding each resulting refname to setup_revisions. Commit 468224e5
refactored this to simply mark the pending objects, saving an extra
lookup.
However, it confused the "flags" parameter to the each_ref_fn
clalback, which is about the flags we found while looking up the ref
with the object flag. Because REF_ISSYMREF ("this ref is a symbolic
ref, e.g. refs/remotes/origin/HEAD") happens to be the same bit
pattern as SEEN ("we have picked this object up from the pending
list and moved it to revs.commits list"), we incorrectly reported
that a commit previously at the detached HEAD will become
unreachable if the only ref that can reach the commit happens to be
pointed at by a symbolic ref.

* tg/ce-namelen-field:
Strip namelen out of ce_flags into a ce_namelen field
The identity of the committer will ultimately be pulled from
the ident code by commit_tree(). However, we make an attempt
to check the author and committer identity early, before the
user has done any manual work like inputting a commit
message. That lets us abort without them having to worry
about salvaging the work from .git/COMMIT_EDITMSG.
The early check for committer ident does not use the
IDENT_STRICT flag, meaning that it would not find an empty
name field. The motivation was presumably because we did not
want to be too restrictive, as later calls might be more lax
(for example, when we create the reflog entry, we do not
care too much about a real name). However, because
commit_tree will always get a strict identity to put in the
commit object itself, there is no point in being lax only to
die later (and in fact it is harmful, because the user will
have wasted time typing their commit message).
Incidentally, this bug was masked prior to 060d4bb, as the
initial loose call would taint the later strict call. So the
commit would succeed (albeit with a bogus committer line in
the commit object), and nobody noticed that our early check
did not match the later one.

When the unpack_data function is given a consume() callback,
it unpacks only 64K of the input at a time, feeding it to
git_inflate along with a 64K output buffer. However,
because we are inflating, there is a good chance that the
output buffer will fill before consuming all of the input.
In this case, we need to loop on git_inflate until we have
fed the whole input buffer, feeding each chunk of output to
the consume buffer.
The current code does not do this, and as a result, will
fail the loop condition and trigger a fatal "serious inflate
inconsistency" error in this case.
While we're rearranging the loop, let's get rid of the
extra last_out pointer. It is meant to point to the
beginning of the buffer that we feed to git_inflate, but in
practice this is always the beginning of our same 64K
buffer, because:
1. At the beginning of the loop, we are feeding the
buffer.
2. At the end of the loop, if we are using a consume()
function, we reset git_inflate's pointer to the
beginning of the buffer. If we are not using a
consume() function, then we do not care about the value
of last_out at all.

Now we have all the necessary logic to fall back on three-way merge when
the patch does not cleanly apply, insert the conflicted entries to the
index as appropriate. This obviously triggers only when the "--index"

When we fall back to three-way merge and some of the merges fail, just
like the case where the "--reject" option was specified and we had to
write some "*.rej" files out for unapplicable patches, exit the command
with non-zero status without showing the diffstat and summary. Otherwise

When a patch does not apply to what we have, but we know the preimage the
patch was made against, we apply the patch to the preimage to compute what
the patch author wanted the result to look like, and attempt a three-way

the base version.
When we are applying the patch using the index, we would additionally need

Mac OS X mangles file names containing unicode on file systems HFS+,
VFAT or SAMBA. When a file using unicode code points outside ASCII
is created on a HFS+ drive, the file name is converted into
decomposed unicode and written to disk. No conversion is done if
the file name is already decomposed unicode.
Calling open("\xc3\x84", ...) with a precomposed "Ä" yields the same
result as open("\x41\xcc\x88",...) with a decomposed "Ä".
As a consequence, readdir() returns the file names in decomposed
unicode, even if the user expects precomposed unicode. Unlike on
HFS+, Mac OS X stores files on a VFAT drive (e.g. an USB drive) in
precomposed unicode, but readdir() still returns file names in
decomposed unicode. When a git repository is stored on a network
share using SAMBA, file names are send over the wire and written to
disk on the remote system in precomposed unicode, but Mac OS X
readdir() returns decomposed unicode to be compatible with its
behaviour on HFS+ and VFAT.
The unicode decomposition causes many problems:
- The names "git add" and other commands get from the end user may
often be precomposed form (the decomposed form is not easily input
from the keyboard), but when the commands read from the filesystem
to see what it is going to update the index with already is on the
filesystem, readdir() will give decomposed form, which is different.
- Similarly "git log", "git mv" and all other commands that need to
compare pathnames found on the command line (often but not always
precomposed form; a command line input resulting from globbing may
be in decomposed) with pathnames found in the tree objects (should
be precomposed form to be compatible with other systems and for
consistency in general).
- The same for names stored in the index, which should be
precomposed, that may need to be compared with the names read from
readdir().
NFS mounted from Linux is fully transparent and does not suffer from
the above.
As Mac OS X treats precomposed and decomposed file names as equal,
we can
- wrap readdir() on Mac OS X to return the precomposed form, and
- normalize decomposed form given from the command line also to the
precomposed form,
to ensure that all pathnames used in Git are always in the
precomposed form. This behaviour can be requested by setting
"core.precomposedunicode" configuration variable to true.
The code in compat/precomposed_utf8.c implements basically 4 new
functions: precomposed_utf8_opendir(), precomposed_utf8_readdir(),
precomposed_utf8_closedir() and precompose_argv(). The first three
are to wrap opendir(3), readdir(3), and closedir(3) functions.
The argv[] conversion allows to use the TAB filename completion done
by the shell on command line. It tolerates other tools which use
readdir() to feed decomposed file names into git.
When creating a new git repository with "git init" or "git clone",
"core.precomposedunicode" will be set "false".
The user needs to activate this feature manually. She typically
sets core.precomposedunicode to "true" on HFS and VFAT, or file
systems mounted via SAMBA.

A path containing a space must be quoted when used as an
argument to either the copy or rename commands (because
unlike other commands, the path is not the final thing on
the line for those commands).
Commit 6280dfdc3b (fast-export: quote paths in output,
2011-08-05) previously attempted to fix fast-export's
quoting by passing all paths through quote_c_style().
However, that function does not consider the space to be a
character which requires quoting, so let's special-case the
space inside print_path(). This will cause space-containing
paths to also be quoted in other commands where such quoting
is not strictly necessary, but it does not hurt to do so.
The test from 6280dfdc3b did not detect this because, while
it does introduce renames in the export stream, it does not
actually turn on rename detection, so they were presented as
pairs of deletions/adds. Using "-M" reveals the bug.

frontends, 2008-05-26) duplicated the one-liner from
cmd_diff to turn on the pager.
Later, commit 8f0359f (Allow pager of diff command be
enabled/disabled, 2008-07-21) taught the the version in
cmd_diff to respect the pager.diff config, but the version
in diff_no_index was left behind. This meant that
git -c pager.diff=0 diff a b
would not use a pager, but
git -c pager.diff=0 diff --no-index a b
would. Let's fix it by factoring out a common function.
While we're there, let's update the antiquated comment,
which claims that the pager interferes with propagating the
exit code; this has not been the case since ea27a18 (spawn
pager via run_command interface, 2008-07-22).

In commit e01105 Linus introduced gitlinks to update-index. He explains
that he thinks it is not the right thing to replace a gitlink with
something else.
That commit is from the very first beginnings of submodule support.
Since then we have gotten a lot closer to being able to remove a
submodule without losing its history. This check prevents such a use
case, so I think this assumption has changed.
Additionally in the git add codepath we do not have such a check, so for
consistency reasons I think removing this check is the correct thing to
do.

"git ls-files --exclude=t/ -i" does not show paths in directory t/
that have been added to the index, but it should.
The excluded() API was designed for callers who walk the tree from
the top, checking each level of the directory hierarchy as it
descends if it is excluded, and not even bothering to recurse into
an excluded directory. This would allow us optimize for a common
case by not having to check if the exclude pattern "foo/" matches
when looking at "foo/bar", because the caller should have noticed
that "foo" is excluded and did not even bother to read "foo/bar"
out of opendir()/readdir() to call it.
The code for "ls-files -i" however walks the index linearly, feeding
paths without checking if the leading directory is already excluded.
Introduce a helper function path_excluded() to let this caller
properly call excluded() check for higher hierarchies as necessary.

When adding the information from a tag, put an empty line between the
message of the tag and the commented-out signature verification
information.
At least for the kernel workflow, I often end up re-formatting the message
that people send me in the tag data. In that situation, putting the tag
message and the tag signature verification back-to-back then means that
normal editor "reflow parapgraph" command will get confused and think that
the signature is a continuation of the last message paragraph.
So I always end up having to first add an empty line, and then go back and
reflow the last paragraph. Let's just do it in git directly.
The extra vertical space also makes the verification visually stand out
more from the user-supplied message, so it looks a bit more readable to me
too, but that may be just an odd personal preference.

Before commit 43ae9f4, we generated the tail of a message id
by calling git_committer_info and parsing the email out of
the result. 43ae9f4 changed to use ident_default_email
directly, so we didn't have to bother with parsing. As a
side effect, it meant we no longer used GIT_COMMITTER_EMAIL
at all.
In general, this is probably reasonable behavior. Either the
default email is sane on your system, or you are using
user.email to provide something sane. The exception is if
you rely on GIT_COMMITTER_EMAIL being set all the time to
override the bogus generated email.
This is unlikely to match anybody's real-life setup, but we
do use it in the test environment. And furthermore, it's
what we have always done, and the change in 43ae9f4 was
about cleaning up, not fixing any bug; we should be
conservative and keep the behavior identical.

unpack_raw_entry() will not allocate and return decompressed blobs if
they are larger than core.bigFileThreshold. sha1_object() may not be
called on those objects because there's no actual content.
sha1_object() is called later on those objects, where we can safely
use get_data_from_pack() to retrieve blob content for checking.
However we always do that when we definitely need the blob
content. And we often don't.
There are two cases when we may need object content. The first case is
when we find an in-repo blob with the same SHA-1. We need to do
collision test, byte-on-byte. If this test is on, the blob must be
loaded on memory (i.e. no streaming). Normally (e.g. in
fetch/pull/clone) this does not happen because git avoid to send
objects that client already has.
The other case is when --strict is specified and the object in
question is not a blob, which can't happen in reality becase we deal
with large _blobs_ here.
Note: --verify (or git-verify-pack) a pack from current repository
will trigger collision test on every object in the pack, which
effectively disables this patch. This could be easily worked around by
setting GIT_DIR to an imaginary place with no packs.

Neither were very convenient for formatting a new HEAD-reference.

The current code reads the config and command-line options
into a separate "colopts" variable, and then copies the
contents of that variable into the "struct wt_status". We
can eliminate the extra variable and copy just write
straight into the wt_status struct.
This simplifies the "status" code a little bit.
Unfortunately, it makes the "commit" code one line more
complex; a side effect of the separate variable was that
"commit" did not copy the colopts variable, so any
column.status configuration had no effect.
The result still ends up cleaner, though. In the previous
version, it was unclear whether commit simply forgot to copy
the colopt variable, or whether it was intentional. Now it
explicitly turns off column options. Furthermore, if commit
later learns to respect column.status, this will make the
end result simpler. I punted on just adding that feature

There is no reason not to, as the user has to explicitly ask

it explicitly, simplifying the code.

This option is passed separately to the wt_status printing

The options are declared as a static global, but really they
need only be accessible from cmd_commit. Additionally,
declare the "struct wt_status" in cmd_commit and cmd_status
as static at the top of each function; this will let the
options lists reference them directly, which will facilitate
further cleanups.

When we show a reflog selector (e.g., via "git log -g"), we
perform some DWIM magic: while we normally show the entry's
index (e.g., HEAD@{1}), if the user has given us a date
with "--date", then we show a date-based select (e.g.,
HEAD@{yesterday}).
However, we don't want to trigger this magic if the
alternate date format we got was from the "log.date"
configuration; that is not sufficiently strong context for
us to invoke this particular magic. To fix this, commit
f4ea32f (improve reflog date/number heuristic, 2009-09-24)
introduced a "date_mode_explicit" flag in rev_info. This
flag is set only when we see a "--date" option on the
command line, and we a vanilla date to the reflog code if
the date was not explicit.
Later, commit 8f8f547 (Introduce new pretty formats %g[sdD]
for reflog information, 2009-10-19) added another way to
show selectors, and it did not respect the date_mode_explicit
flag from f4ea32f.
This patch propagates the date_mode_explicit flag to the
pretty-print code, which can then use it to pass the
appropriate date field to the reflog code. This brings the
behavior of "%gd" in line with the other formats, and means
that its output is independent of any user configuration.

The send_pack function gets a "progress" flag saying "yes,
definitely show progress" or "no, definitely do not show
progress". This gets set properly by transport_push when
send_pack is called directly.
However, when the send-pack command is executed separately
(as it is for the remote-curl helper), there is no way to
tell it "definitely do this". As a result, we do not
properly respect "git push --no-progress" for smart-http
remotes; you will still get progress if stderr is a tty.
This patch teaches send-pack --progress and --no-progress,
and teaches remote-curl to pass the appropriate option to
override send-pack's isatty check. This fixes the
--no-progress case above, and as a bonus, also makes "git
push --progress" work when stderr is not a tty.

The send_pack_args struct has two verbosity flags: "quiet"
and "progress". Originally, if "quiet" was set, we would
tell pack-objects explicitly to be quiet, and if "progress"
was set, we would tell it to show progress. Otherwise, we
told it neither, and it relied on isatty(2) to make the
decision itself.
However, commit 01fdc21 changed the meaning of these
variables. Now both "quiet" and "!progress" instruct us to
tell pack-objects to be quiet (and a non-zero "progress"
means the same as before). This works well for transports
which call send_pack directly, as the transport code copies
transport->progress into send_pack_args->progress, and they
both have the same meaning.
However, the code path of calling "git send-pack" was left
behind. It always sets "progress" to 0, and thus always
tells pack-objects to be quiet. We can work around this by
checking isatty(2) ourselves in the cmd_send_pack code path,
restoring the original behavior of the send-pack command.

When calling "git push" without argument, we want to allow Git to do
something simple to explain and safe. push.default=matching is unsafe
when used to push to shared repositories, and hard to explain to
beginners in some contexts. It is debatable whether 'upstream' or
'current' is the safest or the easiest to explain, so introduce a new
mode called 'simple' that is the intersection of them: push to the
upstream branch, but only if it has the same name remotely. If not, give
an error that suggests the right command to push explicitely to
'upstream' or 'current'.
A question is whether to allow pushing when no upstream is configured. An
argument in favor of allowing the push is that it makes the new mode work
in more cases. On the other hand, refusing to push when no upstream is
configured encourages the user to set the upstream, which will be
beneficial on the next pull. Lacking better argument, we chose to deny
the push, because it will be easier to change in the future if someone
shows us wrong.

The git-cherry-pick --allow-empty command by default only preserves empty
commits that were originally empty, i.e only those commits for which
<commit>^{tree} and <commit>^^{tree} are equal. By default commits which are
non-empty, but were made empty by the inclusion of a prior commit on the current
history are filtered out. This option allows us to override that behavior and
include redundant commits as empty commits in the change history.
Note that this patch changes the default behavior of git cherry-pick slightly.
Prior to this patch all commits in a cherry-pick sequence were applied and git
commit was run. The implication here was that, if a commit was redundant, and
the commit did not trigger the fast forward logic, the git commit operation, and
therefore the git cherry-pick operation would fail, displaying the cherry pick
advice (i.e. run git commit --allow-empty). With this patch however, such
redundant commits are automatically skipped without stopping, unless
--keep-redundant-commits is specified, in which case, they are automatically
applied as empty commits.

git-gc executes many sub-commands. The argument list for
some of these is constant, but for others we add more
arguments at runtime. The latter is implemented by allocating
a constant extra number of NULLs, and either using a custom
append function, or just referencing unused slots by number.
As of commit 7e52f56, which added two new arguments, it is
possible to exceed the constant number of slots for "repack"
by running "git gc --aggressive", causing "git gc" to die.
This patch converts all of the static argv lists to use
argv-array. In addition to fixing the overflow caused by
7e52f56, it has a few advantages:
1. We can drop the custom append function (which,
incidentally, had an off-by-one error exacerbating the
static limit).
2. We can drop the ugly magic numbers used when adding
arguments to "prune".
3. Adding further arguments will be easier; you can just
add new "push" calls without worrying about increasing
any static limits.

Instead of waiting until we record the parents of resulting merge, reduce
redundant parents (including our HEAD) immediately after reading them.
The change to t7602 illustrates the essence of the effect of this change.
The octopus merge strategy used to be fed with redundant commits only to

Since 88a21979c (fetch/pull: recurse into submodules when necessary) all
fetched commits are examined if they contain submodule changes (unless
configuration or command line options inhibit that). If a newly recorded
submodule commit is not present in the submodule, a fetch is run inside
it to download that commit.
Checking new refs was done in an else branch where it wasn't executed for
tags. This normally isn't a problem because tags are only fetched with
the branches they live on, then checking the new commits in the fetched
branches for submodule commits will also process all tags. But when a
specific tag is fetched (or the refspec contains refs/tags/) commits only
reachable by tags won't be searched for submodule commits, which is a bug.
Fix that by moving the code outside the if/else construct to handle new
tags just like any other ref. The performance impact of adding tags that
most of the time lie on a branch which is checked anyway for new submodule
commit should be minimal, as since 6859de4 (fetch: avoid quadratic loop
checking for updated submodules) all ref-tips are collected first and then
fed to a single rev-list.

When we pack everything into one big pack with "git repack
-Ad", any unreferenced objects in to-be-deleted packs are
exploded into loose objects, with the intent that they will
be examined and possibly cleaned up by the next run of "git
prune".
Since the exploded objects will receive the mtime of the
pack from which they come, if the source pack is old, those
loose objects will end up pruned immediately. In that case,
it is much more efficient to skip the exploding step
entirely for these objects.
This patch teaches pack-objects to receive the expiration
information and avoid writing these objects out. It also
teaches "git gc" to pass the value of gc.pruneexpire to
repack (which in turn learns to pass it along to
pack-objects) so that this optimization happens
automatically during "git gc" and "git gc --auto".

The user can say "git push" without specifying any refspec. When using
the "upstream" semantics via the push.default configuration, the user
wants to update the "upstream" branch of the current branch, which is the
branch at a remote repository the current branch is set to integrate with,
with this command.
However, there are cases that such a "git push" that uses the "upstream"
semantics does not make sense:
- The current branch does not have branch.$name.remote configured. By
definition, "git push" that does not name where to push to will not
know where to push to. The user may explicitly say "git push $there",
but again, by definition, no branch at repository $there is set to
integrate with the current branch in this case and we wouldn't know
which remote branch to update.
- The current branch does have branch.$name.remote configured, but it
does not specify branch.$name.merge that names what branch at the
remote this branch integrates with. "git push" knows where to push in
this case (or the user may explicitly say "git push $remote" to tell us
where to push), but we do not know which remote branch to update.
- The current branch does have its remote and upstream branch configured,
but the user said "git push $there", where $there is not the remote
named by "branch.$name.remote". By definition, no branch at repository
$there is set to integrate with the current branch in this case, and
this push is not meant to update any branch at the remote repository
$there.
The first two cases were already checked correctly, but the third case was
not checked and we ended up updating the branch named branch.$name.merge
at repository $there, which was totally bogus.

If a remote repo has too many tags (or branches), cloning it over the
smart HTTP transport can fail because remote-curl.c puts all the refs
from the remote repo on the fetch-pack command line. This can make the
command line longer than the global OS command line limit, causing
fetch-pack to fail.
This is especially a problem on Windows where the command line limit is
orders of magnitude shorter than Linux. There are already real repos out
there that msysGit cannot clone over smart HTTP due to this problem.
Here is an easy way to trigger this problem:
git init too-many-refs
cd too-many-refs
echo bla > bla.txt
git add .
git commit -m test
sha=$(git rev-parse HEAD)
tag=$(perl -e 'print "bla" x 30')
for i in `seq 50000`; do
echo $sha refs/tags/$tag-$i >> .git/packed-refs
done
Then share this repo over the smart HTTP protocol and try cloning it:
$ git clone http://localhost/.../too-many-refs/.git
Cloning into 'too-many-refs'...
fatal: cannot exec 'fetch-pack': Argument list too long
50k tags is obviously an absurd number, but it is required to
demonstrate the problem on Linux because it has a much more generous
command line limit. On Windows the clone fails with as little as 500
tags in the above loop, which is getting uncomfortably close to the
number of tags you might see in real long lived repos.
This is not just theoretical, msysGit is already failing to clone our
company repo due to this. It's a large repo converted from CVS, nearly
10 years of history.
Four possible solutions were discussed on the Git mailing list (in no
particular order):
1) Call fetch-pack multiple times with smaller batches of refs.
This was dismissed as inefficient and inelegant.
2) Add option --refs-fd=$n to pass a an fd from where to read the refs.
This was rejected because inheriting descriptors other than
stdin/stdout/stderr through exec() is apparently problematic on Windows,
plus it would require changes to the run-command API to open extra
pipes.
3) Add option --refs-from=$tmpfile to pass the refs using a temp file.
This was not favored because of the temp file requirement.
4) Add option --stdin to pass the refs on stdin, one per line.
In the end this option was chosen as the most efficient and most
desirable from scripting perspective.
There was however a small complication when using stdin to pass refs to
fetch-pack. The --stateless-rpc option to fetch-pack also uses stdin for
communication with the remote server.
If we are going to sneak refs on stdin line by line, it would have to be
done very carefully in the presence of --stateless-rpc, because when
reading refs line by line we might read ahead too much data into our
buffer and eat some of the remote protocol data which is also coming on
stdin.
One way to solve this would be to refactor get_remote_heads() in
fetch-pack.c to accept a residual buffer from our stdin line parsing
above, but this function is used in several places so other callers
would be burdened by this residual buffer interface even when most of
them don't need it.
In the end we settled on the following solution:
If --stdin is specified without --stateless-rpc, fetch-pack would read
the refs from stdin one per line, in a script friendly format.
However if --stdin is specified together with --stateless-rpc,
fetch-pack would read the refs from stdin in packetized format
(pkt-line) with a flush packet terminating the list of refs. This way we
can read the exact number of bytes that we need from stdin, and then
get_remote_heads() can continue reading from the same fd without losing
a single byte of remote protocol data.
This way the --stdin option only loses generality and scriptability when
used together with --stateless-rpc, which is not easily scriptable
anyway because it also uses pkt-line when talking to the remote server.

Pushing a non-fast-forward update to a remote repository will result in
an error, but the hint text doesn't provide the correct resolution in
every case. Give better resolution advice in three push scenarios:
1) If you push your current branch and it triggers a non-fast-forward
error, you should merge remote changes with 'git pull' before pushing
again.
2) If you push to a shared repository others push to, and your local
tracking branches are not kept up to date, the 'matching refs' default
will generate non-fast-forward errors on outdated branches. If this is
your workflow, the 'matching refs' default is not for you. Consider
setting the 'push.default' configuration variable to 'current' or
'upstream' to ensure only your current branch is pushed.
3) If you explicitly specify a ref that is not your current branch or
push matching branches with ':', you will generate a non-fast-forward
error if any pushed branch tip is out of date. You should checkout the
offending branch and merge remote changes before pushing again.
Teach transport.c to recognize these scenarios and configure push.c
to hint for them. If 'git push's default behavior changes or we
discover more scenarios, extension is easy. Standardize on the
advice API and add three new advice variables, 'pushNonFFCurrent',
'pushNonFFDefault', and 'pushNonFFMatching'. Setting any of these
to 'false' will disable their affiliated advice. Setting
'pushNonFastForward' to false will disable all three, thus preserving the
config option for users who already set it, but guaranteeing new
users won't disable push advice accidentally.

As we already walk the history of the branch that gets merged to
come up with a short log, let's label it with names of the primary
authors, so that the user who summarizes the merge can easily give
credit to them in the log message.
Also infer the names of "lieutents" to help integrators at higher
level of the food-chain to give credit to them, by counting:
* The committer of the 'tip' commit that is merged
* The committer of merge commits that are merged
Often the first one gives the owner of the history being pulled, but
his last pull from his sublieutenants may have been a fast-forward,
in which case the first one would not be. The latter rule will
count the integrator of the history, so together it might be a
reasonable heuristics.
There are two special cases:
- The "author" credit is omitted when the series is written solely
by the same author who is making the merge. The name can be seen
on the "Author" line of the "git log" output to view the log
message anyway.
- The "lieutenant" credit is omitted when there is only one key
committer in the merged branch and it is the committer who is
making the merge. Typically this applies to the case where the
developer merges his own branch.

Default to the real terminal width for diff --stat output, instead
of the hard-coded 80 columns.
Some projects (especially in Java), have long filename paths, with
nested directories or long individual filenames. When files are
renamed, the filename part in stat output can be almost useless. If
the middle part between { and } is long (because the file was moved to
a completely different directory), then most of the path would be
truncated.
It makes sense to detect and use the full terminal width and display
full filenames if possible.
The are commands like diff, show, and log, which can adapt the output
to the terminal width. There are also commands like format-patch,
whose output should be independent of the terminal width. Since it is
safer to use the 80-column default, the real terminal width is only
used if requested by the calling code by setting diffopts.stat_width=-1.
Normally this value is 0, and can be set by the user only to a
non-negative value, so -1 is safe to use internally.
This patch only changes the diff builtin to use the full terminal width.

pointer is returned. When the object doesn't exist, it tries to
dereference a NULL pointer. This can be the case when git branch
--merged is given an argument that isn't a valid commit name.
Check whether the lookup returns a NULL pointer and die with an error
if it does. Add a test, while we're at it.

The heuristic used by "git merge" to decide if it automatically gives an
editor upon clean automerge is to see if the standard input and the
standard output is the same device and is a tty, we are in an interactive
session. "The same device" test was done by comparing fstat(2) result on
the two file descriptors (and they must match), and we asked isatty() only
for the standard input (we insist that they are the same device and there
is no point asking tty-ness of the standard output).
The stat(2) emulation in the Windows port however does not give a usable
value in the st_ino field, so even if the standard output is connected to
something different from the standard input, "The same device" test may
incorrectly return true. To accomodate it, add another isatty() check for
the standard output stream as well.

It can be useful to split your ~/.gitconfig across multiple
files. For example, you might have a "main" file which is
used on many machines, but a small set of per-machine
tweaks. Or you may want to make some of your config public
(e.g., clever aliases) while keeping other data back (e.g.,
your name or other identifying information). Or you may want
to include a number of config options in some subset of your
repos without copying and pasting (e.g., you want to
reference them from the .git/config of participating repos).
This patch introduces an include directive for config files.
It looks like:
[include]
path = /path/to/file
This is syntactically backwards-compatible with existing git
config parsers (i.e., they will see it as another config
entry and ignore it unless you are looking up include.path).
The implementation provides a "git_config_include" callback
which wraps regular config callbacks. Callers can pass it to
git_config_from_file, and it will transparently follow any
include directives, passing all of the discovered options to
the real callback.
Include directives are turned on automatically for "regular"
git config parsing. This includes calls to git_config, as
well as calls to the "git config" program that do not
specify a single file (e.g., using "-f", "--global", etc).
They are not turned on in other cases, including:
1. Parsing of other config-like files, like .gitmodules.
There isn't a real need, and I'd rather be conservative
and avoid unnecessary incompatibility or confusion.
2. Reading single files via "git config". This is for two
reasons:
a. backwards compatibility with scripts looking at
config-like files.
b. inspection of a specific file probably means you
care about just what's in that file, not a general
lookup for "do we have this value anywhere at
all". If that is not the case, the caller can
always specify "--includes".
3. Writing files via "git config"; we want to treat
include.* variables as literal items to be copied (or
modified), and not expand them. So "git config
--unset-all foo.bar" would operate _only_ on
.git/config, not any of its included files (just as it
also does not operate on ~/.gitconfig).

The git-config command sometimes operates on the default set
of config files (either reading from all, or writing to repo
config), and sometimes operates on a specific file. In the
latter case, we set the magic global config_exclusive_filename,
and the code in config.c does the right thing.
Instead, let's have git-config use the "advanced" variants
of config.c's functions which let it specify an individual
filename (or NULL for the default). This makes the code a
lot more obvious, and fixes two small bugs:
1. A relative path specified by GIT_CONFIG=foo will look
in the wrong directory if we have to chdir as part of
repository setup. We already handle this properly for
"git config -f foo", but the GIT_CONFIG lookup used
config_exclusive_filename directly. By dropping to a
single magic variable, the GIT_CONFIG case now just
works.
2. Calling "git config -f foo --edit" would not respect
core.editor. This is because just before editing, we
called git_config, which would respect the
config_exclusive_filename setting, even though this
particular git_config call was not about looking in the
user's specified file, but rather about loading actual
git config, just as any other git program would.

"git tag -n" did not check the type of the object it is reading the top n
lines from. At least, avoid showing the beginning of trees and blobs when
dealing with lightweight tags that point at them.
As the payload of a tag and a commit look similar in that they both start
with a header block, which is skipped for the purpose of "-n" output,
followed by human readable text, allow the message of commit objects to be
shown just like the contents of tag objects. This avoids regression for
people who have been using "tag -n" to show the log messages of commits
that are pointed at by lightweight tags.

When the userdiff_config function was introduced in be58e70
(diff: unify external diff and funcname parsing code,
2008-10-05), it used a return value convention unlike any
other config callback. Like other callbacks, it used "-1" to
signal error. But it returned "1" to indicate that it found
something, and "0" otherwise; other callbacks simply
returned "0" to indicate that no error occurred.
This distinction was necessary at the time, because the
userdiff namespace overlapped slightly with the color
configuration namespace. So "diff.color.foo" could mean "the
'foo' slot of diff coloring" or "the 'foo' component of the
"color" userdiff driver". Because the color-parsing code
would die on an unknown color slot, we needed the userdiff
code to indicate that it had matched the variable, letting
us bypass the color-parsing code entirely.
Later, in 8b8e862 (ignore unknown color configuration,
2009-12-12), the color-parsing code learned to silently
ignore unknown slots. This means we no longer need to
protect userdiff-matched variables from reaching the
color-parsing code.
We can therefore change the userdiff_config calling
convention to a more normal one. This drops some code from
each caller, which is nice. But more importantly, it reduces
the cognitive load for readers who may wonder why
userdiff_config is unlike every other config callback.
There's no need to add a new test confirming that this
works; t4020 already contains a test that sets
diff.color.external.

$ git checkout master

This incidentally also errors out --edit-description when the HEAD points
at an unborn branch (immediately after "init", or "checkout --orphan"),
because at that point, you do not even have any commit that is part of
your history and there is no point in describing how this particular
branch is different from the branch it forked off of, which is the useful

Starting at release v1.7.9, if you ask to merge a signed tag, "git merge"
always creates a merge commit, even when the tag points at a commit that
happens to be a descendant of your current commit.
Unfortunately, this interacts rather badly for people who use --ff-only to
make sure that their branch is free of local developments. It used to be
possible to say:
$ git checkout -b frotz v1.7.9~30
$ git merge --ff-only v1.7.9
and expect that the resulting tip of frotz branch matches v1.7.9^0 (aka
the commit tagged as v1.7.9), but this fails with the updated Git with:
fatal: Not possible to fast-forward, aborting.
because a merge that merges v1.7.9 tag to v1.7.9~30 cannot be created by
fast forwarding.
We could teach users that now they have to do
$ git merge --ff-only v1.7.9^0
but it is far more pleasant for users if we DWIMmed this ourselves.
When an integrator pulls in a topic from a lieutenant via a signed tag,
even when the work done by the lieutenant happens to fast-forward, the
integrator wants to have a merge record, so the integrator will not be
asking for --ff-only when running "git pull" in such a case. Therefore,

When you specify a local repository on the command line of
clone, ls-remote, upload-pack, receive-pack, or upload-archive,
or in a request to git-daemon, we perform a little bit of
lookup magic, doing things like looking in working trees for
.git directories and appending ".git" for bare repos.
For clone, this magic happens in get_repo_path. For
everything else, it happens in enter_repo. In both cases,
there are some ambiguous or confusing cases that aren't
handled well, and there is one case that is not handled the
same by both methods.
This patch tries to provide (and test!) standard, sensible
lookup rules for both code paths. The intended changes are:
1. When looking up "foo", we have always preferred
a working tree "foo" (containing "foo/.git" over the
bare "foo.git". But we did not prefer a bare "foo" over
"foo.git". With this patch, we do so.
2. We would select directories that existed but didn't
actually look like git repositories. With this patch,
we make sure a selected directory looks like a git
repo. Not only is this more sensible in general, but it
will help anybody who is negatively affected by change
(1) negatively (e.g., if they had "foo.git" next to its
separate work tree "foo", and expect to keep finding
"foo.git" when they reference "foo").
3. The enter_repo code path would, given "foo", look for
"foo.git/.git" (i.e., do the ".git" append magic even
for a repo with working tree). The clone code path did
not; with this patch, they now behave the same.
In the unlikely case of a working tree overlaying a bare
repo (i.e., a ".git" directory _inside_ a bare repo), we
continue to treat it as a working tree (prefering the
"inner" .git over the bare repo). This is mainly because the
combination seems nonsensical, and I'd rather stick with
existing behavior on the off chance that somebody is relying
on it.

The low-level grep_source code will automatically load the
userdiff driver to see whether a file is binary. However,
when we are threaded, it will load the drivers in a
non-deterministic order, handling each one as its assigned
thread happens to be scheduled.
Meanwhile, the attribute lookup code (which underlies the
userdiff driver lookup) is optimized to handle paths in
sequential order (because they tend to share the same
gitattributes files). Multi-threading the lookups destroys
the locality and makes this optimization less effective.
We can fix this by pre-loading the userdiff driver in the
main thread, before we hand off the file to a worker thread.
My best-of-five for "git grep foo" on the linux-2.6
repository went from:
real 0m0.391s
user 0m1.708s
sys 0m0.584s
to:
real 0m0.360s
user 0m1.576s
sys 0m0.572s
Not a huge speedup, but it's quite easy to do. The only
trick is that we shouldn't perform this optimization if "-a"
was used, in which case we won't bother checking whether
the files are binary at all.

The grep_source interface (as opposed to grep_buffer) will
eventually gives us a richer interface for telling the
low-level grep code about our buffers. Eventually this will
lead to things like better binary-file handling. For now, it
lets us drop a lot of now-redundant code.
The conversion is mostly straight-forward. One thing to note
is that the memory ownership rules for "struct grep_source"
are different than the "struct work_item" found here (the
former will copy things like the filename, rather than
taking ownership). Therefore you will also see some slight

The multi-threaded git-grep code needs to serialize access
to the thread-unsafe read_sha1_file call. It does this with
a mutex that is local to builtin/grep.c.
Let's instead push this down into grep.c, where it can be
used by both builtin/grep.c and grep.c. This will let us

The low-level grep code traditionally didn't care about
threading, as it doesn't do any threading itself and didn't
call out to other non-thread-safe code. That changed with
0579f91 (grep: enable threading with -p and -W using lazy
attribute lookup, 2011-12-12), which pushed the lookup of
funcname attributes (which is not thread-safe) into the
low-level grep code.
As a result, the low-level code learned about a new global
"grep_attr_mutex" to serialize access to the attribute code.
A multi-threaded caller (e.g., builtin/grep.c) is expected
to initialize the mutex and set "use_threads" in the
grep_opt structure. The low-level code only uses the lock if
use_threads is set.
However, putting the use_threads flag into the grep_opt
struct is not the most logical place. Whether threading is
in use is not something that matters for each call to
grep_buffer, but is instead global to the whole program
(i.e., if any thread is doing multi-threaded grep, every
other thread, even if it thinks it is doing its own
single-threaded grep, would need to use the locking). In
practice, this distinction isn't a problem for us, because
the only user of multi-threaded grep is "git-grep", which
does nothing except call grep.
This patch turns the opt->use_threads flag into a global
flag. More important than the nit-picking semantic argument
above is that this means that the locking functions don't
need to actually have access to a grep_opt to know whether
to lock. Which in turn can make adding new locks simpler, as

Before f824628 (merge: use editor by default in interactive sessions,

asked for it with --edit. Thus it seemed unlikely that the user would
need extra guidance.
After f824628 the _normal_ thing is to start an editor. Give at least
an indication of why we are doing it.
The sentence about justification is one of the few things about
standard git that are not agnostic to the workflow that the user
chose. However, f824628 was proposed by Linus specifically to
discourage users from merging unrelated upstream progress into topic
branches. So we may as well take another step in the same direction.

6f48d39 (clone: delay cloning until after remote HEAD checking -
2012-01-16) allows us to perform some checks on remote refs before the
actual cloning happens. But not all transport types support
this. Remote helper with "import" capability will not return complete
ref information until fetch is performed and therefore the clone cannot
be delayed.
foreign_vcs field in struct remote was used to detect this kind of transport
and save the result. This is a mistake because foreign_vcs is designed
to override url-based transport detection. As a result, if the same
"struct transport *" object is used on many different urls and one of
them attached remote transport, the following urls will be mistakenly
attached to the same transport. This fault is worked around by dad0b3d
(push: do not let configured foreign-vcs permanently clobbered -
2012-01-23)
To fix this, detect incomplete refs from transport_get_remote_refs()
by SHA-1. Incomplete ones must have null SHA-1 (*). Then revert
changes related to foreign_cvs field in 6f48d39 and dad0b3d.
A good thing from this change is that cloning smart http transport can
also be delayed. Earlier it falls into the same category "remote
transport, no delay".
(*) Theoretically if one of the remote refs happens to have null SHA-1,
it will trigger false alarm and the clone will not be delayed. But
that chance may be too small for us to pay attention to.

Recently, 6f48d39 (clone: delay cloning until after remote HEAD checking,
2012-01-16) tried to record if a remote helper needs to be called after
parsing the remote when transport_get() is called, by overwriting the
field meant to store the configured remote helper name in the remote
structure.
This is OK when a remote represents a single remote repository, but fails
miserably when pushing to locations with multiple URLs, like this:
$ cat .git/config
[remote "origin"]
url = https://code.google.com/p/git-htmldocs/
url = github.com:gitster/git-htmldocs.git
push = refs/heads/master:refs/heads/master
$ git push
The second url that is supposed to use the git-over-ssh transport
mistakenly use https:// and fails with:
error: Couldn't resolve host 'github.com:gitster' while accessing
github.com:gitster/git-htmldocs.git/info/refs
fatal: HTTP request failed
The right solution would probably be to dedicate a separate field to store
the detected external helper to be used, which is valid only during a
single use of transport until it is disconnected, instead of overwriting
foreign_vcs field, but in the meantime, this band-aid should suffice.

Traditionally, a cleanly resolved merge was committed by "git merge" using
the auto-generated merge commit log message without invoking the editor.
After 5 years of use in the field, it turns out that people perform too
many unjustified merges of the upstream history into their topic branches.
These merges are not just useless, but they are often not explained well,
and making the end result unreadable when it gets time for merging their
history back to their upstream.
Earlier we added the "--edit" option to the command, so that people can
edit the log message to explain and justify their merge commits. Let's
take it one step further and spawn the editor by default when we are in an
interactive session (i.e. the standard input and the standard output are
pointing at the same tty device).
There may be existing scripts that leave the standard input and the
standard output of the "git merge" connected to whatever environment the
scripts were started, and such invocation might trigger the above
"interactive session" heuristics. GIT_MERGE_AUTOEDIT environment variable
can be set to "no" at the beginning of such scripts to use the historical
behaviour while the script runs.
Note that this backward compatibility is meant only for scripts, and we
deliberately do *not* support "merge.edit = yes/no/auto" configuration
option to allow people to keep the historical behaviour.

In threaded mode, git-grep emits file breaks (enabled with context, -W

skip the first such line in the output, which would otherwise be at
the very top.
This is wrong when the user also specified -l/-L/-c, in which case
every line is relevant. While arguably giving these options together
doesn't make any sense, git-grep has always quietly accepted it. So

write_remote_refs() creates new packed refs from references obtained
from the remote repository, which is "out of thin air" as far as the
local repository is concerned. Previously it did this by creating
"extra" refs, then calling pack_refs() to bake them into the

Current find_unresolved_deltas() links all bases together in a form of
tree, using struct base_data, with prev_base pointer to point to
parent node. Then it traverses down from parent to children in
recursive manner with all base_data allocated on stack.
To eliminate recursion, we simply need to put all on heap
(parse_pack_objects and fix_unresolved_deltas). After that, it's
simple non-recursive depth-first traversal loop. Each node also
maintains its own state (ofs and ref indices) to iterate over all
children nodes.
So we process one node:
- if it returns a new (child) node (a parent base), we link it to our
tree, then process the new node.
- if it returns nothing, the node is done, free it. We go back to
parent node and resume whatever it's doing.
and do it until we have no nodes to process.

thin-pack: try harder to use preferred base objects as base
When creating a pack using objects that reside in existing packs, we try
to avoid recomputing futile delta between an object (trg) and a candidate
for its base object (src) if they are stored in the same packfile, and trg
is not recorded as a delta already. This heuristics makes sense because it
is likely that we tried to express trg as a delta based on src but it did
not produce a good delta when we created the existing pack.
As the pack heuristics prefer producing delta to remove data, and Linus's
law dictates that the size of a file grows over time, we tend to record
the newest version of the file as inflated, and older ones as delta
against it.
When creating a thin-pack to transfer recent history, it is likely that we
will try to send an object that is recorded in full, as it is newer. But
the heuristics to avoid recomputing futile delta effectively forbids us
from attempting to express such an object as a delta based on another
object. Sending an object in full is often more expensive than sending a
suboptimal delta based on other objects, and it is even more so if we
could use an object we know the receiving end already has (i.e. preferred
base object) as the delta base.
Tweak the recomputation avoidance logic, so that we do not punt on
computing delta against a preferred base object.
The effect of this change can be seen on two simulated upload-pack
workloads. The first is based on 44 reflog entries from my git.git
origin/master reflog, and represents the packs that kernel.org sent me git
updates for the past month or two. The second workload represents much
larger fetches, going from git's v1.0.0 tag to v1.1.0, then v1.1.0 to
v1.2.0, and so on.
The table below shows the average generated pack size and the average CPU
time consumed for each dataset, both before and after the patch:
dataset
| reflog | tags
---------------------------------
before | 53358 | 2750977
size after | 32398 | 2668479
change | -39% | -3%
---------------------------------
before | 0.18 | 1.12
CPU after | 0.18 | 1.15
change | +0% | +3%
This patch makes a much bigger difference for packs with a shorter slice
of history (since its effect is seen at the boundaries of the pack) though
it has some benefit even for larger packs.

We have been carefully choosing feature names used in the protocol
extensions so that the vocabulary does not contain a word that is a
substring of another word, so it is not a real problem, but we have
recently added "quiet" feature word, which would mean we cannot later
add some other word with "quiet" (e.g. "quiet-push"), which is awkward.
Let's make sure that we can eventually be able to do so by teaching the
clients and servers that feature words consist of non whitespace
letters. This parser also allows us to later add features with parameters
e.g. "feature=1.5" (parameter values need to be quoted for whitespaces,
but we will worry about the detauls when we do introduce them).

The FETCH_HEAD refname is supposed to refer to the ref that was fetched
and should be merged. However all fetched refs are written to
.git/FETCH_HEAD in an arbitrary order, and resolve_ref_unsafe simply
takes the first ref as the FETCH_HEAD, which is often the wrong one,
when other branches were also fetched.
The solution is to write the for-merge ref(s) to FETCH_HEAD first.
Then, unless --append is used, the FETCH_HEAD refname behaves as intended.
If the user uses --append, they presumably are doing so in order to
preserve the old FETCH_HEAD.
While we are at it, update an old example in the read-tree documentation

Advice messages are by definition meant for human end-users, and prime
candidates for i18n/l10n. They tend to also be more verbose to be helpful,
and need to be longer than just one line.
Although we do not have parameterized multi-line advice messages yet, once
we do, we cannot emit such a message like this:
advise(_("Please rename %s to something else"), gostak);
advise(_("so that we can avoid distimming %s unnecessarily."), doshes);
because some translations may need to have the replacement of 'gostak' on
the second line (or 'doshes' on the first line). Some languages may even
need to use three lines in order to fit the same message within a
reasonable width.
Instead, it has to be a single advise() construct, like this:
advise(_("Please rename %s to something else\n"
"so that we can avoid distimming %s unnecessarily."),
gostak, doshes);
Update the advise() function and its existing callers to
- take a format string that can be multi-line and translatable as a
whole;
- use the string and the parameters to form a localized message; and
- show each line in the result with the localization of the "hint: ".

Maintaining an array of hashes is easier using sha1_array than
open-coding it. This patch also fixes a leak of the SHA1 array
in diff_tree_combined_merge().

Measurements by various people have shown that grepping in parallel is
not beneficial when the object store is involved. For example, with a
simple regex:
Threads | --cached case | worktree case
----------------------------------------------------------------
8 (default) | 2.88u 0.21s 0:02.94real | 0.19u 0.32s 0:00.16real
4 | 2.89u 0.29s 0:02.99real | 0.16u 0.34s 0:00.17real
2 | 2.83u 0.36s 0:02.87real | 0.18u 0.32s 0:00.26real
NO_PTHREADS | 2.16u 0.08s 0:02.25real | 0.12u 0.17s 0:00.31real
This happens because all the threads contend on read_sha1_mutex almost
all of the time. A more complex regex allows the threads to do more
work in parallel, but as Jeff King found out, the "super boost" (much
higher clock when only one core is active) feature of recent CPUs
still causes the unthreaded case to win by a large margin.
So until the pack machinery allows unthreaded access, we disable
grep's threading in all but the worktree case.

Lazily load the userdiff attributes in match_funcname(). Use a
separate mutex around this loading to protect the (not thread-safe)
attributes machinery. This lets us re-enable threading with -p and
-W while reducing the overhead caused by looking up attributes.

format_todo() calls get_message(), but uses only the subject line of
the commit message. As a minor optimization, save work and
unnecessary memory allocations by using find_commit_subject() instead.
Also, remove the unnecessary check on cur->item->buffer: the
lookup_commit_reference() call in parse_insn_line() has already made
sure of this.

Tolerate extra spaces and tabs as part of the the field separator in
