Even during a conflicted merge, "git blame $path" always meant to
blame uncommitted changes to the "working tree" version; make it
more useful by showing cleanly merged parts as coming from the other
branch that is being merged.
This incidentally fixes an unrelated problem on a case insensitive
filesystem, where "git blame MAKEFILE" run in a history that has
"Makefile" but not "MAKEFILE" did not say "No such file MAKEFILE in
HEAD" but pretended as if "MAKEFILE" was a newly added file.

places to be mistakenly rejected (most notably, binary patch that

"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.

"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
this particular case, the blame should fail, as the history for the
file in that contents has not been committed yet at the point in the
test.

fetch_populated_submodules() allocates the full argv array it uses to
recurse into the submodules from the number of given options plus the six
argv values it is going to add. It then initializes it with those values
which won't change during the iteration and copies the given options into
it. Inside the loop the two argv values different for each submodule get
replaced with those currently valid.
However, this technique is brittle and error-prone (as the comment to
explain the magic number 6 indicates), so let's replace it with an
argv_array. Instead of replacing the argv values, push them to the
argv_array just before the run_command() call (including the option
separating them) and pop them from the argv_array right after that.

Fetch invokes itself recursively when recursing into
submodules or handling "fetch --multiple". In both cases, it
builds the child's command line by pushing options onto a
statically-sized array. In both cases, the array is
currently just big enough to handle the largest possible
case. However, this technique is brittle and error-prone, so
let's replace it with a dynamic argv_array.

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.

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.
Noticed by Colin McCabe.

Either end of revision range operator can be omitted to default to HEAD,
as in "origin.." (what did I do since I forked) or "..origin" (what did
they do since I forked). But the current parser interprets ".." as an
empty range "HEAD..HEAD", and worse yet, because ".." does exist on the
filesystem, we get this annoying output:
$ cd Documentation/howto
$ git log .. ;# give me recent commits that touch Documentation/ area.
fatal: ambiguous argument '..': both revision and filename
Use '--' to separate filenames from revisions
Surely we could say "git log ../" or even "git log -- .." to disambiguate,
but we shouldn't have to.

Before reading a config file, we check "!access(path, R_OK)"
to make sure that the file exists and is readable. If it's
not, then we silently ignore it.
For the case of ENOENT, this is fine, as the presence of the
file is optional. For other cases, though, it may indicate a
configuration error (e.g., not having permissions to read
the file). Let's print a warning in these cases to let the
user know.

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.

"git prune" reports removal of loose object files that are no longer
necessary only under the "-v" option, but unconditionally reports
removal of temporary files that are no longer needed.
The original thinking was that the presence of a leftover temporary
file should be an unusual occurrence that may indicate an earlier
failure of some sort, and the user may want to be reminded of it.
Removing an unnecessary loose object file, on the other hand, is
just part of the normal operation. That is why the former is always
printed out and the latter only when -v is used.
But neither report is particularly useful. Hide both of these
behind the "-v" option for consistency.

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.
