Contrary to the documentation on credential helpers, as well as the help
text for git-credential-netrc itself, this helper will `die` when
presented with an unknown property/attribute/token.
Correct the behaviour here by skipping and ignoring any tokens that are
unknown. This means all helpers in the tree are consistent and ignore
any unknown credential properties/attributes.

It is the expectation that credential helpers be liberal in what they
accept and conservative in what they return, to allow for future growth
and evolution of the protocol/interaction.
All of the other helpers (store, cache, osxkeychain, libsecret,
gnome-keyring) except `netrc` currently ignore any credential lines
that are not recognised, whereas the Windows helper (wincred) instead
dies.
Fix the discrepancy and ignore unknown lines in the wincred helper.

remote: handle rename of remote without fetch refspec
We return an error when trying to rename a remote that has no fetch
refspec:
$ git config --unset-all remote.origin.fetch
$ git remote rename origin foo
fatal: could not unset 'remote.foo.fetch'
To make things even more confusing, we actually _do_ complete the config
modification, via git_config_rename_section(). After that we try to
rewrite the fetch refspec (to say refs/remotes/foo instead of origin).
But our call to git_config_set_multivar() to remove the existing entries
fails, since there aren't any, and it calls die().
We could fix this by using the "gently" form of the config call, and
checking the error code. But there is an even simpler fix: if we know
that there are no refspecs to rewrite, then we can skip that part
entirely.

clone: allow "--bare" with "-o"
We explicitly forbid the combination of "--bare" with "-o", but there
doesn't seem to be any good reason to do so. The original logic came as
part of e6489a1bdf (clone: do not accept more than one -o option.,
2006-01-22), but that commit does not give any reason.
Furthermore, the equivalent combination via config is allowed:
git -c clone.defaultRemoteName=foo clone ...

useless, because a bare clone does not set remote.origin.fetch (and
hence there is no refs/remotes/origin hierarchy). But it does set
remote.origin.url, and that name is visible to the user via "git fetch
origin", etc.

Since commit c54980ab83 (list-objects-filter: convert filter_spec to a
strbuf, 2022-09-11), building with SANITIZE=undefined triggers an error
in t5616.
The problem is that we end up with a strbuf that has been
zero-initialized instead of via STRBUF_INIT. Feeding that strbuf to
strbuf_addbuf() in list_objects_filter_copy() means we will call memcpy
like:
memcpy(some_actual_buffer, NULL, 0);
This works on most systems because we're copying zero bytes, but it is
technically undefined behavior to ever pass NULL to memcpy.
Even though c54980ab83 is where the bug manifests, that is only because
we switched away from a string_list, which is OK with being
zero-initialized (though it may cause other problems by not duplicating
the strings, it happened to be OK in this instance).
The actual bug is caused by the commit before that, 2a01bdedf8
(list-objects-filter: add and use initializers, 2022-09-11). There we
consistently initialize the top-level filter structs, but we forgot the
dynamically allocated ones we stick in filter_options->sub when creating
combined filters.
Note that we need to fix two spots here: where we parse a "combine:"
filter, but also where we transform from a single-filter into a combined
one after seeing multiple "--filter" options. In the second spot, we'll
do some minor refactoring to avoid repeating our very-long array index.

parse_object_buffer(): respect save_commit_buffer
If the global variable "save_commit_buffer" is set to 0, then
parse_commit() will throw away the commit object data after parsing it,
rather than sticking it into a commit slab. This goes all the way back
to 60ab26de99 ([PATCH] Avoid wasting memory in git-rev-list,
2005-09-15).
But there's another code path which may similarly stash the buffer:
parse_object_buffer(). This is where we end up if we parse a commit via
parse_object(), and it's used directly in a few other code paths like
git-fsck.
The original goal of 60ab26de99 was avoiding extra memory usage for
rev-list. And there it's not all that important to catch parse_object().
We use that function only for looking at the tips of the traversal, and
the majority of the commits are parsed by following parent links, where
we use parse_commit() directly. So we were wasting some memory, but only
a small portion.
It's much easier to see the effect with fsck. Since we now turn off
save_commit_buffer by default there, we _should_ be able to drop the
freeing of the commit buffer in fsck_obj(). But if we do so (taking the
first hunk of this patch without the rest), then the peak heap of "git
fsck" in a clone of git.git goes from 136MB to 194MB. Teaching
parse_object_buffer() to respect save_commit_buffer brings that down to
134.5MB (it's hard to tell from massif's output, but I suspect the
savings comes from avoiding the overhead of the mostly-empty commit
slab).
Other programs should see a small improvement. Both "rev-list --all" and
"fsck --connectivity-only" improve by a few hundred kilobytes, as they'd
avoid loading the tip objects of their traversals.
Most importantly, no code should be hurt by doing this. Any program that
turns off save_commit_buffer is already making the assumption that any
commit it sees may need to have its object data loaded on demand, as it
doesn't know which ones were parsed by parse_commit() versus
parse_object(). Not to mention that anything parsed by the commit graph
may be in the same boat, even if save_commit_buffer was not disabled.
This should be the only spot that needs to be fixed. Grepping for
set_commit_buffer() shows that this and parse_commit() are the only
relevant calls.

fsck: turn off save_commit_buffer
When parsing a commit, the default behavior is to stuff the original
buffer into a commit_slab (which takes ownership of it). But for a tool
like fsck, this isn't useful. While we may look at the buffer further as
part of fsck_commit(), we'll always do so through a separate pointer;
attaching the buffer to the slab doesn't help.
Worse, it means we have to remember to free the commit buffer in all
call paths. We do so in fsck_obj(), which covers a regular "git fsck".
But with "--connectivity-only", we forget to do so in both
traverse_one_object(), which covers reachable objects, and
mark_unreachable_referents(), which covers unreachable ones. As a
result, that mode ends up storing an uncompressed copy of every commit
on the heap at once.
We could teach the code paths for --connectivity-only to also free
commit buffers. But there's an even easier fix: we can just turn off the
save_commit_buffer flag, and then we won't attach them to the commits in
the first place.
This reduces the peak heap of running "git fsck --connectivity-only" in
a clone of linux.git from ~2GB to ~1GB. According to massif, the
remaining memory goes where you'd expect: the object structs themselves,
the obj_hash containing them, and the delta base cache.
Note that we'll leave the call to free commit buffers in fsck_obj() for
now; it's not quite redundant because of a related bug that we'll fix in
a subsequent commit.

fsck: free tree buffers after walking unreachable objects
After calling fsck_walk(), a tree object struct may be left in the
parsed state, with the full tree contents available via tree->buffer.
It's the responsibility of the caller to free these when it's done with
the object to avoid having many trees allocated at once.
In a regular "git fsck", we hit fsck_walk() only from fsck_obj(), which
does call free_tree_buffer(). Likewise for "--connectivity-only", we see
most objects via traverse_one_object(), which makes a similar call.
The exception is in mark_unreachable_referents(). When using both
"--connectivity-only" and "--dangling" (the latter of which is the
default), we walk all of the unreachable objects, and there we forget to
free. Most cases would not notice this, because they don't have a lot of
unreachable objects, but you can make a pathological case like this:
git clone --bare /path/to/linux.git repo.git
cd repo.git
rm packed-refs ;# now everything is unreachable!
git fsck --connectivity-only
That ends up with peak heap usage ~18GB, which is (not coincidentally)
close to the size of all uncompressed trees in the repository. After
this patch, the peak heap is only ~2GB.
A few things to note:
- it might seem like fsck_walk(), if it is parsing the trees, should
be responsible for freeing them. But the situation is quite tricky.
In the non-connectivity mode, after we call fsck_walk() we then
proceed with fsck_object() which actually does the type-specific
sanity checks on the object contents. We do pass our own separate
buffer to fsck_object(), but there's a catch: our earlier call to
parse_object_buffer() may have attached that buffer to the object
struct! So by freeing it, we leave the rest of the code with a
dangling pointer.
Likewise, the call to fsck_walk() in index-pack is subtle. It
attaches a buffer to the tree object that must not be freed! And
so rather than calling free_tree_buffer(), it actually detaches it
by setting tree->buffer to NULL.
These cases would _probably_ be fixable by having fsck_walk() free
the tree buffer only when it was the one who allocated it via
parse_tree(). But that would still leave the callers responsible for
freeing other cases, so they wouldn't be simplified. While the
current semantics for fsck_walk() make it easy to accidentally leak
in new callers, at least they are simple to explain, and it's not a
function that's likely to get a lot of new call-sites.
And in any case, it's probably sensible to fix the leak first with
this simple patch, and try any more complicated refactoring
separately.
- a careful reader may notice that fsck_obj() also frees commit
buffers, but neither the call in traverse_one_object() nor the one
touched in this patch does so. And indeed, this is another problem
for --connectivity-only (and accounts for most of the 2GB heap after
this patch), but it's one we'll fix in a separate commit.

pack is eligible to be expired.
This is less than desireable, since the cruft pack has important

determine how quickly an object should age out of the repository when
pruning.
Ordinarily, we wouldn't expect the contents of a cruft pack to
duplicated across non-cruft packs (and we'd expect to see the MIDX
select all cruft objects from other sources even less often). But
nonetheless, it is still possible to trick the `expire` sub-command into

'ref_type' would have the symref option).
Instead, enum ref_worktree_type only makes explicit how a refname
relates to a worktree. From this point of view, HEAD and
refs/bisect/abc are the same: they specify the current worktree
implicitly.
The files-backend must avoid packing refs/bisect/* and friends into
packed-refs, so expose is_per_worktree_ref() separately.

diagnose.c: refactor to safely use 'd_type'
Refactor usage of the 'd_type' property of 'struct dirent' in 'diagnose.c'
to instead utilize the compatibility macro 'DTYPE()'. On systems where
'd_type' is not present in 'struct dirent', this macro will always return
'DT_UNKNOWN'. In that case, instead fall back on using the 'stat.st_mode' to
determine whether the dirent points to a dir, file, or link.
Additionally, add a test to 't0092-diagnose.sh' to verify that files (e.g.,
loose objects) are counted properly.
Note that the new function 'get_dtype()' is based on 'resolve_dtype()' in
'dir.c' (which itself was refactored from a prior 'get_dtype()' in ad6f2157f9 (dir: restructure in a way to avoid passing around a struct
dirent, 2020-01-16)), but differs in that it is meant for use on arbitrary
files, such as those inside the '.git' dir. Because of this, it does not
search the index for a matching entry to derive the 'd_type'.

fuzz: reorganise the path for existing oss-fuzz fuzzers
In order to provide a better organisation for oss-fuzz fuzzers and
to avoid top-level clustters in the git repository when more fuzzers
are introduced, move the existing fuzzer-related sources to their
own oss-fuzz/ hierarchy. Grouping the fuzzers into their own
directory, separate their application on fuzz-testing from the core
functionalities of the git code, prvides better and tidier structure
the oss-fuzz fuzzing library to manage, locate, build and execute
those fuzzers for fuzz-testing purposes in future development.

The speed of the merged_iter_pqueue_add() can be improved by using a
pointer to the pq_entry struct, which is 96 bytes. Since the pq_entry
param is worked directly on the stack and does not currently have a
pointer to it, the merged_iter_pqueue_add() function is slightly
slower.
References to pq_entry in reftable have typically included pointers,
such as both of the params for pq_less().
Since we are working with pointers in the pq_entry param, as keenly
pointed out, the pq_entry param has also been made into a const since
the contents of the pq_entry param are copied and not manipulated.

t1800: correct test to handle Cygwin
On Cygwin, when failing to spawn a process using start_command, Git
outputs the same error as on Linux systems, rather than using the
GIT_WINDOWS_NATIVE-specific error output. The WINDOWS test prerequisite
is set in both Cygwin and native Windows environments, which means it's
not appropriate to use to anticipate the error output from
start_command. Instead, use the MINGW test prerequisite, which is only
set for Git in native Windows environments, and not for Cygwin.

A side note: the original report was about cyrillic filenames.
After some investigations it turned out that
a) This is not a problem with "ambiguous characters" in unicode
b) The same problem exists for all unicode code points (so we
can use Latin based Umlauts for demonstrations below)
The 'Ä' takes the same space on the screen as the 'A'.
But needs one more byte in memory, so the the `git log --stat` output
for "Arger.txt" (!) gets mis-aligned:
The maximum length is derived from "Ärger.txt", 10 bytes in memory,
9 positions on the screen. That is why "Arger.txt" gets one extra ' '
for aligment, it needs 9 bytes in memory.
If there was a file "Ö", it would be correctly aligned by chance,
but "Öhö" would not.
The solution is of course, to use utf8_strwidth() instead of strlen()
when dealing with the width on screen.
And then there is another problem, code like this:
strbuf_addf(&out, "%-*s", len, name);
(or using the underlying snprintf() function) does not align the
buffer to a minimum of len measured in screen-width, but uses the
memory count.
One could be tempted to wish that snprintf() was UTF-8 aware.
That doesn't seem to be the case anywhere (tested on Linux and Mac),
probably snprintf() uses the "bytes in memory"/strlen() approach to be
compatible with older versions and this will never change.
The basic idea is to change code in diff.c like this
strbuf_addf(&out, "%-*s", len, name);
into something like this:
int padding = len - utf8_strwidth(name);
if (padding < 0)
padding = 0;
strbuf_addf(&out, " %s%*s", name, padding, "");
The real change is slighty bigger, as it, as well, integrates two calls
of strbuf_addf() into one.
Tests:
Two things need to be tested:
- The calculation of the maximum width
- The calculation of padding
The name "textfile" is changed into "tëxtfilë", both have a width of 8.
If strlen() was used, to get the maximum width, the shorter "binfile" would
have been mis-aligned:
binfile | [snip]
tëxtfilë | [snip]
If only "binfile" would be renamed into "binfilë":
binfilë | [snip]
textfile | [snip]
In order to verify that the width is calculated correctly everywhere,
"binfile" is renamed into "binfilë", giving 1 bytes more in strlen()
"tëxtfile" is renamed into "tëxtfilë", 2 byte more in strlen().
The updated t4012-diff-binary.sh checks the correct aligment:
binfilë | [snip]
tëxtfilë | [snip]
