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.

In case 'git cherry-pick -s <commit>' failed, the user had to use 'git
commit -s' (i.e. state the -s option again), which is easy to forget
about. Instead, write the signed-off-by line early, so plain 'git
commit' will have the same result.
Also update 'git commit -s', so that in case there is already a relevant
Signed-off-by line before the Conflicts: line, it won't add one more at
the end of the message. If there is no such line, then add it before the
the Conflicts: line.

It used to be that if "--all", "--depth", and also explicit references

in filter_refs() because the "--all --depth" code took precedence over
the explicit reference handling, and the explicit references were
never noted as having been found. So check for explicitly sought
references before proceeding to the "--all --depth" logic.

"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

causing an internal error and the fix was about avoiding it.

fetch_populated_submodules() allocates the full argv array it uses to

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

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.

Either end of revision range operator can be omitted to default to HEAD,

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
git branch --set-upstream-to origin/master

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

The original thinking was that the presence of a leftover temporary

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

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).

"git checkout <branchname>" to come back from a detached HEAD state
incorrectly computed reachability of the detached HEAD, resulting in
unnecessary warnings.
* 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.

Split lower bits of ce_flags field and creates a new ce_namelen

* 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.

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"
option is used.
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
merge between the result and our version, using the intended preimage as
the base version.
When we are applying the patch using the index, we would additionally need

But the top-level directory of the working tree is created by

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.

It was stupid of me to make the API too much cache-entry specific;
the caller may want to check arbitrary pathname without having a
corresponding cache-entry to see if a path is ignored.

"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.

git usually streams large blobs directly to packs. But there are cases
where git can create large loose blobs (unpack-objects or hash-object
over pipe). Or they can come from other git implementations.
core.bigfilethreshold can also be lowered down and introduce a new
wave of large loose blobs.
Use streaming interface to read/compress/write these blobs in one
go. Fall back to normal way if somehow streaming interface cannot be
used.

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.

Callers who ask for ERROR_ON_NO_NAME are not so much
concerned that the name will be blank (because, after all,
we will fall back to using the username), but rather it is a
check to make sure that low-quality identities do not end up
in things like commit messages or emails (whereas it is OK
for them to end up in things like reflogs).
When future commits add more quality checks on the identity,
each of these callers would want to use those checks, too.
Rather than modify each of them later to add a new flag,
let's refactor the flag.

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.

If stderr isn't a tty, we shouldn't be printing incremental progress
messages. In particular, this affects 'git checkout -f . >&logfile'
unless you provided -q. And git-new-workdir has no way to provide -q.
It would probably be better to have progress.c check isatty(2) all the time,
but that wouldn't allow things like 'git push --progress' to force progress
reporting to on, so I won't try to solve the general case right now.

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.

These should typically be sorted already, but they do come

about performance degrading in the common case that the list
is already sorted.
