"git bundle" learned that "-" is a common way to say that the input
comes from the standard input and/or the output goes to the

When an object is not found in a repository's object store, we sometimes
call reprepare_packed_git() to see if the object was temporarily moved
into a new pack-file (and its old pack-file or loose object was
deleted). This process does a scan of each pack directory within each
odb, but does not reevaluate if the odb list needs updating.
Extend reprepare_packed_git() to also reprepare the alternate odb list
by setting loaded_alternates to zero and calling prepare_alt_odb(). This
will add newly-discoverd odbs to the linked list, but will not duplicate
existing ones nor will it remove existing ones that are no longer listed
in the alternates file. Do this under the object read lock to avoid
readers from interacting with a potentially incomplete odb being added
to the odb list.
If the alternates file was edited to _remove_ some alternates during the
course of the Git process, Git will continue to see alternates that were
ever valid for that repository. ODBs are not removed from the list, the
same as the existing behavior before this change. Git already has
protections against an alternate directory disappearing from the
filesystem during the lifetime of a process, and those are still in
effect.
This change is specifically for concurrent changes to the repository, so
it is difficult to create a test that guarantees this behavior is
correct. I manually verified by introducing a reprepare_packed_git() call
into get_revision() and stepped into that call in a debugger with a
parent 'git log' process. Multiple runs of prepare_alt_odb() kept
the_repository->objects->odb as a single-item chain until I added a
.git/objects/info/alternates file in a different process. The next run
added the new odb to the chain and subsequent runs did not add to the
chain.

When we generate a diff with --cached, unmerged entries have no oid for
their index entry:
$ git diff-index --abbrev --cached HEAD
:100644 000000 f719efd 0000000 U my-conflict
So when we are asked to produce a patch, since we only have one side, we
just emit a special message:
$ git diff-index --cached -p HEAD
* Unmerged path my-conflict
This confuses interactive-patch modes that look at cached diffs. For
example:
$ git reset -p
BUG: add-patch.c:498: diff starts with unexpected line:
* Unmerged path my-conflict
Making things even more confusing, you'll get that error only if the
unmerged entry is alphabetically the first changed file. Otherwise, we
simply stick the unrecognized line to the end of the previous hunk.
There it's mostly harmless, as it eventually gets fed back to "git
apply", which happily ignores it. But it's still shown to the user
attached to the hunk, which is wrong.
So let's handle these lines as a noop. There's not really anything
useful to do with a conflicted merge in this case, and that's what we do
for other cases like "add -p". There we get a "diff --cc" line, which we
accept as starting a new file, but we refuse to use any of its hunks
(their headers start with "@@@" and not "@@ ", so we silently ignore
them).
It seems like simply recognizing the line and continuing in our parsing
loop would work. But we actually need to run the rest of the loop body
to handle matching up our colored/filtered output. But that code assumes
that we have some active file_diff we're working on. So instead, we'll
just insert a dummy entry into our array. This ends up the same as if we
saw a "diff --cc" line (a file with no hunks).

The split_cmdline() function introduced in [1] returns an "int". If
it's negative it signifies an error. The option parsing in [2] didn't
account for this, and assigned the value directly to the "size_t
xopts_nr". We'd then attempt to loop over all of these elements, and
access uninitialized memory.
There's a few things that use this for option parsing, but one way to
trigger it is with a bad value to "-X <strategy-option>", e.g:
git rebase -X"bad argument\""
In another context this might be a security issue, but in this case
someone who's already able to inject arguments directly to our
commands would be past other defenses, making this potential
escalation a moot point.
As the example above & test case shows the error reporting leaves
something to be desired. The function will loop over the
whitespace-split values, but when it encounters an error we'll only
report the first element, which is OK, not the second "argument\""
whose quote is unbalanced.
This is an inherent limitation of the current API, and the issue
affects other API users. Let's not attempt to fix that now. If and
when that happens these tests will need to be adjusted to assert the
new output.

The user might not necessarily know why ff only was configured, maybe an
admin did it, or the installer (Git for Windows), or perhaps they just
followed some online advice.
This can happen not only on pull.ff=only, but merge.ff=only too.
Even worse if the user has configured pull.rebase=false and
merge.ff=only, because in those cases a diverging merge will constantly
keep failing. There's no trivial way to get out of this other than
`git merge --no-ff`.
Let's not assume our users are experts in git who completely understand
all their configurations.

When handling OPT_FILENAME(), we have to stick the "prefix" (if any) in
front of the filename to make up for the fact that Git has chdir()'d to
the top of the repository. We can do this with prefix_filename(), but
there are a few special cases we handle ourselves.
Unfortunately the memory allocation is inconsistent here; if we do make
it to prefix_filename(), we'll allocate a string which the caller must
free to avoid a leak. But if we hit our special cases, we'll return the
string as-is, and a caller which tries to free it will crash. So there's
no way to win.
Let's consistently allocate, so that callers can do the right thing.
There are now three cases to care about in the function (and hence a
three-armed if/else):
1. we got a NULL input (and should leave it as NULL, though arguably
this is the sign of a bug; let's keep the status quo for now and we
can pick at that scab later)
2. we hit a special case that means we leave the name intact; we
should duplicate the string. This includes our special "-"
matching. Prior to this patch, it also included empty prefixes and
absolute filenames. But we can observe that prefix_filename()
already handles these, so we don't need to detect them.
3. everything else goes to prefix_filename()
I've dropped the "const" from the "char **file" parameter to indicate
that we're allocating, though in practice it's not really important.
This is all being shuffled through a void pointer via opt->value before
it hits code which ever looks at the string. And it's even a bit weird,
because we are really taking _in_ a const string and using the same
out-parameter for a non-const string. A better function signature would
be:
static char *fix_filename(const char *prefix, const char *file);
but that would mean the caller dereferences the double-pointer (and the
NULL check is currently handled inside this function). So I took the
path of least-change here.
Note that we have to fix several callers in this commit, too, or we'll
break the leak-checking tests. These are "new" leaks in the sense that
they are now triggered by the test suite, but these spots have always
been leaky when Git is run in a subdirectory of the repository. I fixed
all of the cases that trigger with GIT_TEST_PASSING_SANITIZE_LEAK. There
may be others in scripts that have other leaks, but we can fix them
later along with those other leaks (and again, you _couldn't_ fix them
before this patch, so this is the necessary first step).

A user can specify a filename to a command from the command line,
either as the value given to a command line option, or a command
line argument. When it is given as a relative filename, in the
user's mind, it is relative to the directory "git" was started from,
but by the time the filename is used, "git" would almost always have
chdir()'ed up to the root level of the working tree.
The given filename, if it is relative, needs to be prefixed with the
path to the current directory, and it typically is done by calling
prefix_filename() helper function. For commands that can also take
"-" to use the standard input or the standard output, however, this
needs to be done with care.
"git bundle create" uses the next word on the command line as the
output filename, and can take "-" to mean "write to the standard
output". It blindly called prefix_filename(), so running it in a
subdirectory did not quite work as expected.
Introduce a new helper, prefix_filename_except_for_dash(), and use
it to help "git bundle create" codepath.

For writing, "bundle create -" indicates that the bundle should be
written to stdout. But there's no matching handling of "-" for reading
operations. This is inconsistent, and a little inflexible (though one
can always use "/dev/stdin" on systems that support it).
However, it's easy to change. Once upon a time, the bundle-reading code
required a seekable descriptor, but that was fixed long ago in
e9ee84cf28b (bundle: allowing to read from an unseekable fd,
2011-10-13). So we just need to handle "-" explicitly when opening the
file.
We _could_ do this by handling "-" in read_bundle_header(), which the
reading functions all call already. But that is probably a bad idea.
It's also used by low-level code like the transport functions, and we
may want to be more careful there. We do not know that stdin is even
available to us, and certainly we would not want to get confused by a
configured URL that happens to point to "-".
So instead, let's add a helper to builtin/bundle.c. Since both the
bundle code and some of the callers refer to the bundle by name for
error messages, let's use the string "<stdin>" to make the output a bit
nicer to read.

In 79862b6b77c (bundle-create: progress output control, 2019-11-10),
"bundle create" learned about the --all-progress and
--all-progress-implied options, which were copied from pack-objects.
I think these were a mistake.
In pack-objects, "all-progress-implied" is about switching the behavior
between a regular on-disk "git repack" and the use of pack-objects for
push/fetch (where a fetch does not want progress from the server during
the write stage; the client will print progress as it receives the
data). But there's no such distinction for bundles. Prior to
79862b6b77c, we always printed the write stage. Afterwards, a vanilla:
git bundle create foo.bundle
omits the write progress, appearing to hang (especially if your
repository is large or your disk is slow). That seems like a regression.
It's possible that the flexibility to disable the write-phase progress
_could_ be useful for bundle. E.g., if you did something like:
ssh some-host git bundle create foo.bundle |
git bundle unbundle
But if you are running both in real-time, why are you using bundles in
the first place? You're better off doing a real fetch.
But even if we did want to support that, it should be the exception, and
vanilla "bundle create" should display the full progress. So we'd want
to name the option "--no-write-progress" or something.
The "--all-progress" option itself is even worse. It exists in
pack-objects only for historical reasons. It's a mistake because it
implies "--progress", and we added "--all-progress-implied" to fix that.
There is no reason to propagate that mistake to new commands.
Likewise, the documentation for these options was pulled from
pack-objects. But it doesn't make any sense in this context. It talks
about "--stdout", but that is not even an option that git-bundle
supports.
This patch flips the default for "--all-progress-implied" back to
"true", fixing the regression in 79862b6b77c. This turns that option
into a noop, and means that "--all-progress" is really the same as
"--progress". We _could_ drop them completely, but since they've been
shipped with Git since v2.25.0, it's polite to continue accepting them.
I didn't implement any sort of "--no-write-progress" here. I'm not at
all convinced it's necessary, and the discussion from the original
thread:
https://lore.kernel.org/git/20191110204126.30553-2-robbat2@gentoo.org/
shows that that the main focus was on getting --progress and --quiet
support, and not any kind of clever "real-time bundle over the network"
feature. But technically this patch is making it impossible to do
something that you _could_ do post-79862b6b77c.
