Instead of barfing, simply ignore bad object names seen in the
input. This is useful when reading from "git notes list" output
that may refer to objects that have already been garbage collected.
Depending on the application, it is not necessarily an error for an object
to lack a note, especially if the only thing the caller wants to make sure
is that notes are cleared for an object. By passing this option from the
command line, the "git notes remove" command considers it a success if the
object did not have any note to begin with.
While "xargs -n1 git notes rm" is certainly a possible way to remove notes
from many objects, this would create one notes "commit" per removal, which
is not quite suitable for seasonal housekeeping.
Allow taking more than one on the command line, and record their removal
as a single atomic event if everthing goes well.
Even though the old code insisted that "git notes rm" must be given only
one object (or zero, in which case it would default to HEAD), this
condition was not tested. Add tests to handle the new case where we feed
multiple objects, and also make sure if there is a bad input, no change
is recorded.
ls-remote: the --exit-code option reports "no matching refs"
The "git ls-remote" uses its exit status to indicate if it successfully
talked with the remote repository. A new option "--exit-code" makes the
command exit with status "2" when there is no refs to be listed, even when
the command successfully talked with the remote repository.
This way, the caller can tell if we failed to contact the remote, or the
remote did not have what we wanted to see. Of course, you can inspect the
output from the command, which has been and will continue to be a valid
way to check the same thing.

Windows: add a wrapper for the shutdown() system call
Even though Windows's socket functions look like their POSIX counter parts,
they do not operate on file descriptors, but on "socket objects". To bring
the functions in line with POSIX, we have proxy functions that wrap and
unwrap the socket objects in file descriptors using open_osfhandle and
get_osfhandle. But shutdown() was not proxied, yet. Fix this.

On the author's terminal, the up-arrow input sequence is ^[[A, and
thus fat-fingering an up-arrow into 'git checkout -p' is quite
dangerous: git-add--interactive.perl will ignore the ^[ and [
characters and happily treat A as "discard everything".
As a band-aid fix, use Term::Cap to get all terminal capabilities.
Then use the heuristic that any capability value that starts with ^[
(i.e., \e in perl) must be a key input sequence. Finally, given an
input that starts with ^[, read more characters until we have read a
full escape sequence, then return that to the caller. We use a
timeout of 0.5 seconds on the subsequent reads to avoid getting stuck
if the user actually input a lone ^[.
Since none of the currently recognized keys start with ^[, the net
result is that the sequence as a whole will be ignored and the help
displayed.

send-pack: avoid deadlock on git:// push with failed pack-objects
Commit 09c9957c fixes a deadlock in which pack-objects
fails, the remote end is still waiting for pack data, and we
are still waiting for the remote end to say something (see
that commit for a much more in-depth explanation).
We solved the problem there by making sure the output pipe
is closed on error; thus the remote sees EOF, and proceeds
to complain and close its end of the connection.
However, in the special case of push over git://, we don't
have a pipe, but rather a full-duplex socket, with another
dup()-ed descriptor in place of the second half of the pipe.
In this case, closing the second descriptor signals nothing
to the remote end, and we still deadlock.
This patch calls shutdown() explicitly to signal EOF to the
other side.

connect: let callers know if connection is a socket
They might care because they want to do a half-duplex close.
With pipes, that means simply closing the output descriptor;
with a socket, you must actually call shutdown.
Instead of exposing the magic no_fork child_process struct,
let's encapsulate the test in a function.

connect: treat generic proxy processes like ssh processes
The git_connect function returns two ends of a pipe for
talking with a remote, plus a struct child_process
representing the other end of the pipe. If we have a direct
socket connection, then this points to a special "no_fork"
child process.
The code path for doing git-over-pipes or git-over-ssh sets
up this child process to point to the child git command or
the ssh process. When we call finish_connect eventually, we
check wait() on the command and report its return value.
The code path for git://, on the other hand, always sets it
to no_fork. In the case of a direct TCP connection, this
makes sense; we have no child process. But in the case of a
proxy command (configured by core.gitproxy), we do have a
child process, but we throw away its pid, and therefore
ignore its return code.
Instead, let's keep that information in the proxy case, and
respect its return code, which can help catch some errors
(though depending on your proxy command, it will be errors
reported by the proxy command itself, and not propagated
from git commands. Still, it is probably better to propagate
such errors than to ignore them).
It also means that the child_process field can reliably be
used to determine whether the returned descriptors are
actually a full-duplex socket, which means we should be
using shutdown() instead of a simple close.

read_sha1_file(): allow selective bypassing of replacement mechanism
The way "object replacement" mechanism was tucked to the read_sha1_file()
interface was suboptimal in a couple of ways:
- Callers that want it to die with useful diagnosis upon seeing a corrupt
object does not have a way to say that they do not want any object
replacement.
- Callers who do not want it to die but want to handle the errors
themselves are told to arrange to call read_object(), but the function
does not use the replacement mechanism, and also it is a file scope
static function that not many callers can call to begin with.
This adds a read_sha1_file_extended() that takes a set of flags; the
callers of read_sha1_file() passes a flag READ_SHA1_FILE_REPLACE to ask
for object replacement mechanism to kick in.
Later, we could add another flag bit to tell the function to return an
error instead of dying and then remove the misguided "call read_object()
yourself".
In a repository without object replacement, lookup_replace_object() should
be a no-op. Check the flag "read_replace_refs" on the side of the caller,
and bypess a function call when we know we are not dealing with replacement.
Also, even when we are set up to replace objects, if we do not find any
replacement defined, flip that flag off to avoid function call overhead
for all the later object accesses.
As this change the semantics of the flag from "do we need read the
replacement definition?" to "do we need to check with the lookup table?"
the flag needs to be renamed later to something saner, e.g. "use_replace",
when the codebase is calmer, but not now.
read_sha1_file(): get rid of read_sha1_file_repl() madness
Most callers want to silently get a replacement object, and they do not
care what the real name of the replacement object is. Worse yet, no sane
interface to return the underlying object without replacement is provided.
Remove the function and make only the few callers that want the name of
the replacement object find it themselves.
Change the "pot" target to also extract strings from our $(SCRIPT_SH)
files with xgettext(1).
Note that due to Jonathan Nieder's trick of doing "mv $@+ $@" at the
end of the target the "pot" target will now warn:
$ make pot
XGETTEXT po/git.pot
po/git.pot+: warning: Charset "CHARSET" is not a portable encoding name.
Message conversion to user's charset might not work.
This warnings is emitted because xgettext is writing into a non-*.pot
file, it's harmless however. The content that's written out is
equivalent to what it would be if we were writing directly into an
existing POT file with --join-existing.
As part of this change I've eliminated the && chain between xgettext
calls, this is incompatible with $(QUIET_XGETTEXT), if the && is left
in it'll emit:
/bin/sh: @echo: not found
Since it's redundant (the Makefile will stop if there's an error) I've
removed it altogether.

git-sh-i18n--envsubst: our own envsubst(1) for eval_gettext()
Add a git-sh-i18n--envsubst program which is a stripped-down version
of the GNU envsubst(1) program that comes with GNU gettext for use in
the eval_gettext() fallback.
We need a C helper program because implementing eval_gettext() purely
in shell turned out to be unworkable. Digging through the Git mailing
list archives will reveal two shell implementations of eval_gettext
that are almost good enough, but fail on an edge case which is tested
for in the tests which are part of this patch.
These are the modifications I made to envsubst.c as I turned it into
sh-i18n--envsubst.c:
* Added our git-compat-util.h header for xrealloc() and friends.
* Removed inclusion of gettext-specific headers.
* Removed most of main() and replaced it with my own. The modified
version only does option parsing for --variables. That's all it
needs.
* Modified error() invocations to use our error() instead of
error(3).
* Replaced the gettext XNMALLOC(n, size) macro with just
xmalloc(n). Since XNMALLOC() only allocated char's.
* Removed the string_list_destroy function. It's redundant (also in
the upstream code).
* Replaced the use of stdbool.h (a C99 header) by doing the following
replacements on the code:
* s/bool/unsigned short int/g
* s/true/1/g
* s/false/0/g

Submodules: Don't parse .gitmodules when it contains, merge conflicts
Commands like "git status", "git diff" and "git fetch" would fail when the
.gitmodules file contained merge conflicts because the config parser would
call die() when hitting the conflict markers:
"fatal: bad config file line <n> in <path>/.gitmodules"
While this behavior was on the safe side, it is really unhelpful to the
user to have commands like status and diff fail, as these are needed to
find out what's going on. And the error message is only mildly helpful,
as it points to the right file but doesn't mention that it is unmerged.
Users of git gui were not shown any conflicts at all when this happened.
Improve the situation by checking if the index records .gitmodules as
unmerged. When that is the case we can't make any assumptions about the
configuration to be found there after the merge conflict is resolved by
the user, so assume that all recursion is disabled unless .git/config or
the global config say otherwise.

Bigfile: teach "git add" to send a large file straight to a pack
When adding a new content to the repository, we have always slurped
the blob in its entirety in-core first, and computed the object name
and compressed it into a loose object file. Handling large binary
files (e.g. video and audio asset for games) has been problematic
because of this design.
At the middle level of "git add" callchain is an internal API
index_fd() that takes an open file descriptor to read from the
working tree file being added with its size. Teach it to call out to
fast-import when adding a large blob.
The write-out codepath in entry.c::write_entry() should be taught to
stream, instead of reading everything in core. This should not be so
hard to implement, especially if we limit ourselves only to loose
object files and non-delta representation in packfiles.
If the git commits you are submitting contain changes made by
other people, the authorship will not be retained. Change git-p4
