The diff machinery has two ways to detect changes to set the exit code:
Just comparing hashes and comparing blob contents. The latter is needed
if certain changes have to be ignored, e.g. with --ignore-space-change
or --ignore-matching-lines. It's enabled by the diff_options flag
diff_from_contents.
The slower mode as never considered submodules (and subrepos) as changes
with --submodule=diff or --submodule=log, which is inconsistent with
--submodule=short (the default). Fix it.

uninteresting, 2024-06-09) set diff_from_contents if external diff
programs are allowed. This is the default e.g. for git diff, and so
that change exposed the inconsistency much more widely.

When git-interpret-trailers is used to add a trailer to a message that
does not end in a trailing newline, the new trailer is added on the line
immediately following the message instead of as a trailer block
separated from the message by a blank line.
For example, if a message's text was exactly "The subject" with no
trailing newline present, `git interpret-trailers --trailer
my-trailer=true` will result in the following malformed commit message:
The subject
my-trailer: true
While it is generally expected that a commit message should end with a
newline character, git-interpret-trailers should not be returning an
invalid message in this case.
Use `strbuf_complete_line` to ensure that the message ends with a
newline character when reading the input.

It was reported that git-verify-pack(1) has started to crash with Git
v2.46.0 when run outside of a repository. This is another fallout from
c8aed5e8da (repository: stop setting SHA1 as the default object hash,
2024-05-07), where we have stopped setting the default hash algorithm
for `the_repository`. Consequently, code that relies on `the_hash_algo`
will now crash when it hasn't explicitly been initialized, which may be
the case when running outside of a Git repository.
The crash is not in git-verify-pack(1) but instead in git-index-pack(1),
which gets called by the former. Ideally, both of these programs should
be able to identify the hash algorithm used by the packfile and index
without having to rely on external information. But unfortunately, the
format for neither of them is completely self-describing, so it is not
possible to derive that information. This is a design issue that we
should address by introducing a new packfile version that encodes its
object hash.
For now though the more important fix is to not make either of these
programs crash anymore, which we do by falling back to SHA1 when the
object hash is unconfigured. This pessimizes reading packfiles which
use a different hash than SHA1, but restores previous behaviour.

It was reported that creating a stash with `--keep-index
--include-untracked` causes an error when HEAD points to a commit whose
tree is empty:
$ git stash push --keep-index --include-untracked
error: pathspec ':/' did not match any file(s) known to git
This error comes from `git checkout --no-overlay $i_tree -- :/`, which
we execute to reset the working tree to the state in our index. As the
tree generated from the index is empty in our case, ':/' does not match
any files and thus causes git-checkout(1) to error out.
Fix the issue by skipping the checkout when the index tree is empty. As
explained in the in-code comment, this should be the correct thing to do
as there is nothing that we'd have to reset in the first place.

This patch fixes a racy test failure in t4129.
The deletion test added by e95d515141 (apply: canonicalize modes read
from patches, 2024-08-05) wants to make sure that git-apply does not
complain about a non-canonical mode in the patch, even if that mode does
not match the working tree file. So it does this:
echo content >non-canon &&
git add non-canon &&
chmod 666 non-canon &&
This is wrong, because running chmod will update the ctime on the file,
making it stat-dirty and causing git-apply to refuse to apply the patch.
But this only happens sometimes, since it depends on the timestamps
crossing a second boundary (but it triggers pretty quickly when run with
--stress).
We can fix this by doing the chmod before updating the index. The order
isn't important here, as the mode will be canonicalized to 100644 in the
index anyway (in fact, the chmod is not even that important in the first
place, since git-apply will only look at the index; I only added it as
an extra confirmation that git-apply would not be confused by it).

We hit a segfault when trying to open a bundle via `git bundle
list-heads` when running outside of a repository. This is caused by
c8aed5e8da (repository: stop setting SHA1 as the default object hash,
2024-05-07), which stopped setting the default object hash so that
`the_hash_algo` is a `NULL` pointer when running outside of any repo.
This is only a symptom of a deeper issue though. Bundles default to the
SHA1 object format unless they advertise an "@object-format=" header.
Consequently, it has been wrong in the first place to use the object
format used by the current repository when parsing bundles. The
consequence is that trying to open a bundle that uses a different object
hash than the current repository will fail:
$ git bundle list-heads sha1.bundle
error: unrecognized header: ee4b540943284700a32591ad09f7e15bdeb2a10c HEAD (45)
Fix the bug by defaulting to the SHA1 object hash. We already handle the
"@object-format=" header as expected, so we don't need to adapt this
part.

The `git bundle unbundle` subcommand requires a repository to unbundle
the contents into. As thus, the subcommand checks whether we have a
startup repository in the first place, and if not it dies.
This check happens after we have already opened the bundle though. This
causes a segfault when running outside of a repository starting with
c8aed5e8da (repository: stop setting SHA1 as the default object hash,
2024-05-07) because we have no hash function set up, but we do try to
parse refs advertised by the bundle's header.
The next commit will fix that underlying issue by defaulting to the SHA1
object format for bundles, which will also fix the described segfault here.
But as we know that we will die anyway, we can do better than that and
avoid some vain work by moving the check for a repository before we try
to open the bundle.

When using "git-diff-tree" to get the tree diff for merge commits with
the diff format set to `remerge`, a bug is triggered as shown below:
$ git diff-tree -r --remerge-diff 363337e6eb
363337e6eb812d0c0d785ed4261544f35559ff8b
BUG: log-tree.c:1006: did a remerge diff without remerge_objdir?!?
This bug is reported by `log-tree.c:do_remerge_diff`, where a bug check
added in commit 7b90ab467a (log: clean unneeded objects during log
--remerge-diff, 2022-02-02) detects the absence of `remerge_objdir` when
attempting to clean up temporary objects generated during the remerge
process.
After some further digging, I find that the remerge-related diff options
were introduced in db757e8b8d (show, log: provide a --remerge-diff
capability, 2022-02-02), which also affect the setup of `rev_info` for
"git-diff-tree", but were not accounted for in the original
implementation (inferred from the commit message).
Elijah Newren, the author of the remerge diff feature, notes that other
callers of `log-tree.c:log_tree_commit` (the only caller of
`log-tree.c:do_remerge_diff`) also exist, but:
`builtin/am.c`: manually sets all flags; remerge_diff is not among them
`sequencer.c`: manually sets all flags; remerge_diff is not among them
so `builtin/diff-tree.c` really is the only caller that was overlooked
when remerge-diff functionality was added.
This commit resolves the crash by adding `remerge_objdir` setup logic to
`builtin/diff-tree.c`, mirroring `builtin/log.c:cmd_log_walk_no_free`.
It also includes the necessary cleanup for `remerge_objdir`.

A few tests have "| tee output" downstream of a git command, and
then inspect the contents of the file. The net effect is that we
use an extra process, and hide the exit status from the upstream git

The `grep` statement in this test looks for `d0.*<string>`, attempting
to filter to only show lines that had tabular output where the 2nd
column had `d0` and the final column had a substring of
[`git -c `]`fetch.negotiationAlgorithm`. These lines also have
`child_start` in the 4th column, but this isn't part of the condition.
A subsequent line will have `d1` in the 2nd column, `start` in the 4th
column, and `/path/to/git/git -c fetch.negotiationAlgorihm` in the final
column. If `/path/to/git/git` contains the substring `d0`, then this
line is included by `grep` as well as the desired line, leading to an
effective doubling of the number of lines, and test failures.
Tighten the grep expression to require `d0` to be surrounded by spaces,
and to have the `child_start` label.

To detect conversion failure after calls to functions like `strtod`, one
can check `errno == ERANGE`. These functions are not guaranteed to set
`errno` to `0` on successful conversion, however. Manual manipulation of
`errno` can likely be avoided by checking that the output pointer
differs from the input pointer, but that's not how other locations, such
as parse.c:139, handle this issue; they set errno to 0 prior to
executing the function.
For every place I could find a strtoX function with an ERANGE check
following it, set `errno = 0;` prior to executing the conversion
function.

Git stores only canonical modes for blobs. So for a regular file, we
care about only "100644" or "100755" (depending only on the executable
bit), but never modes where the group or other permissions are more
exotic. So never "100664", "100700", etc. When a file in the working
tree has such a mode, we quietly turn it into one of the two canonical
modes, and that's what is stored both in the index and in tree objects.
However, we don't canonicalize modes we read from incoming patches in
git-apply. These may appear in a few lines:
- "old mode" / "new mode" lines for mode changes
- "new file mode" lines for newly created files
- "deleted file mode" for removing files
For "new mode" and for "new file mode", this is harmless. The patch is
asking the result to have a certain mode, but:
- when we add an index entry (for --index or --cached), it is
canonicalized as we create the entry, via create_ce_mode().
- for a working tree file, try_create_file() passes either 0777 or
0666 to open(), so what you get depends only on your umask, not any
other bits (aside from the executable bit) in the original mode.
However, for "old mode" and "deleted file mode", there is a minor
annoyance. We compare the patch's expected preimage mode with the
current state. But that current state is always going to be a canonical
mode itself:
- updating an index entry via --cached will have the canonical mode in
the index
- for updating a working tree file, check_preimage() runs the mode
through ce_mode_from_stat(), which does the usual canonicalization
So if the patch feeds a non-canonical mode, it's impossible for it to
match, and we will always complain with something like:
file has type 100644, expected 100664
Since this is just a warning, the operation proceeds, but it's
confusing and annoying.
These cases should be pretty rare in practice. Git would never produce a
patch with non-canonical modes itself (since it doesn't store them).
And while we do accept patches from other programs, all of those lines
were invented by Git. So you'd need a program trying to be Git
compatible, but not handling canonicalization the same way. Reportedly
"quilt" is such a program.
We should canonicalize the modes as we read them so that the user never
sees the useless warning.
A few notes on the tests:
- I've covered instances of all lines for completeness, even though
the "new mode" / "new file mode" ones behave OK currently.
- the tests apply patches to both the index and working tree, and
check the result of both. Again, we know that all of these paths
canonicalize anyway, but it's giving us extra coverage (although we
are even less likely to have such a bug now since we canonicalize up
front).
- the test patches are missing "index" lines, which is also something
Git would never produce. But they don't matter for the test, they do
match the case from quilt we saw in the wild, and they avoid some
sha1/sha256 complexity.

In c8aed5e8da (repository: stop setting SHA1 as the default object hash,
2024-05-07), we have stopped setting the default hash algorithm for
`the_repository`. Consequently, code that relies on `the_hash_algo` will
now crash when it hasn't explicitly been initialized, which may be the
case when running outside of a Git repository.
It was reported that git-ls-remote(1) may crash in such a way when using
a remote helper that advertises refspecs. This is because the refspec
announced by the helper will get parsed during capability negotiation.
At that point we haven't yet figured out what object format the remote
uses though, so when run outside of a repository then we will fail.
The course of action is somewhat dubious in the first place. Ideally, we
should only parse object IDs once we have asked the remote helper for
the object format. And if the helper didn't announce the "object-format"
capability, then we should always assume SHA256. But instead, we used to
take either SHA1 if there was no repository, or we used the hash of the
local repository, which is wrong.
Arguably though, crashing hard may not be in the best interest of our
users, either. So while the old behaviour was buggy, let's restore it
for now as a short-term fix. We should eventually revisit, potentially
by deferring the point in time when we parse the refspec until after we
have figured out the remote's object hash.

When using `--fixed-value` with a key whose value is left empty (implied
as being "true"), 'git config' may crash when invoked like either of:
$ git config set --file=config --value=value --fixed-value \
section.key pattern
$ git config --file=config --fixed-value section.key value pattern
The original bugreport[1] bisects to 00bbdde141 (builtin/config:
introduce "set" subcommand, 2024-05-06), which is a red-herring, since
the original bugreport uses the new 'git config set' invocation.
The behavior likely bisects back to c90702a1f6 (config: plumb
--fixed-value into config API, 2020-11-25), which introduces the new
--fixed-value option in the first place.
Looking at the relevant frame from a failed process's coredump, the
crash appears in config.c::matches() like so:
(gdb) up
#1 0x000055b3e8b06022 in matches (key=0x55b3ea894360 "section.key", value=0x0,
store=0x7ffe99076eb0) at config.c:2884
2884 return !strcmp(store->fixed_value, value);
where we are trying to compare the `--fixed-value` argument to `value`,
which is NULL.
Avoid attempting to match `--fixed-value` for configuration keys with no
explicit value. A future patch could consider the empty value to mean
"true", "yes", "on", etc. when invoked with `--type=bool`, but let's
punt on that for now in the name of avoiding the segfault.

Some of the tests in t98xx modify the Perforce depot in ways that the
tool wouldn't normally allow. This is done to test behaviour of git-p4
in certain edge cases that we have observed in the wild, but which
should in theory not be possible.
Naturally, modifying the depot on disk directly is quite intimate with
the tool and thus prone to breakage when Perforce updates the way that
data is stored. And indeed, those tests are broken nowadays with r23 of
Perforce. While a file revision was previously stored as a plain file
"depot/file,v", it is now stored in a directory "depot/file,d" with
compression.
Adapt those tests to handle both old- and new-style depot layouts.

When "git daemon" enters a repository, it chdir's to the requested
repository and then uses "." (the curent directory) to consult the
"is this repository considered safe?" when it is not owned by the
same owner as the process.
Make sure this access will be allowed by setting safe.directory to
".", as that was once advertised on the list as a valid workaround
to the overly tight safe.directory settings introduced by 2.45.1
(cf. <834862fd-b579-438a-b9b3-5246bf27ce8a@gmail.com>).
Also add simlar test to show what happens in the same setting if the
safe.directory is set to "*" instead of "."; in short, "." is a bit
tighter (as it is custom designed for git-daemon situation) than
"anything goes" settings given by "*".

The pathname of a repository comes from getcwd() and it could be a
path aliased via symbolic links, e.g., the real directory may be
/home/u/repository but a symbolic link /home/u/repo may point at it,
and the clone request may come as "git clone file:///home/u/repo/"
A request to check if /home/u/repository is safe would be rejected
if the safe.directory configuration allows /home/u/repo/ but not its
alias /home/u/repository/. Normalize the paths configured for the
safe.directory configuration variable before comparing them with the
path being checked.
Two and a half things to note, compared to the previous step to
normalize the actual path of the suspected repository, are:
- A configured safe.directory may be coming from .gitignore in the
home directory that may be shared across machines. The path
meant to match with an entry may not necessarily exist on all of
such machines, so not being able to convert them to real path on
this machine is *not* a condition that is worthy of warning.
Hence, we ignore a path that cannot be converted to a real path.
- A configured safe.directory is essentially a random string that
user throws at us, written completely unrelated to the directory
the current process happens to be in. Hence it makes little
sense to give a non-absolute path. Hence we ignore any
non-absolute paths, except for ".".
- The safe.directory set to "." was once advertised on the list as
a valid workaround for the regression caused by the overly tight
safe.directory check introduced in 2.45.1; we treat it to mean
"if we are at the top level of a repository, it is OK".

The get_one_patchid() function unconditionally takes a line that
matches the patch header (namely, a line that begins with a full
object name, possibly prefixed by "commit" or "From" plus a space)
as the beginning of a patch. Even when it is *not* looking for one
(namely, when the previous call found the patch header and returned,
and then we are called again to skip the log message and process the
patch whose header was found by the previous invocation).
As a consequence, a line in the commit log message that begins with
one of these patterns can be mistaken to start another patch, with
current message entirely skipped (because we haven't even reached
the patch at all).
Allow the caller to tell us if it called us already and saw the
patch header (in which case we shouldn't be looking for another one,
until we see the "diff" part of the patch; instead we simply should
be skipping these lines as part of the commit log message), and skip
the header processing logic when that is the case. In the helper
function, it also needs to flip this "are we looking for a header?"
bit, once it finished skipping the commit log message and started
processing the patches, as the patch header of the _next_ message is
the only clue in the input that the current patch is done.
