A scheduled "git maintenance" job is expected to work on all
repositories it knows about, but it stopped at the first one that
errored out. Now it keeps going.

The "-k" and "--rfc" options of "format-patch" will now error out
when used together, as one tells us not to add anything to the

Since 5e47215080 (fuzz: add basic fuzz testing target., 2018-10-12), we
have compiled object files for the fuzz tests as part of the default
'make all' target. This helps prevent bit-rot in lesser-used parts of
the codebase, by making sure that incompatible changes are caught at
build time.
However, since we never linked the fuzzer executables, this did not
protect us from link-time errors. As of 8b9a42bf48 (fuzz: fix fuzz test
build rules, 2024-01-19), it's now possible to link the fuzzer
executables without using a fuzzing engine and a variety of
compiler-specific (and compiler-version-specific) flags, at least on
Linux. So let's add a platform-specific option in config.mak.uname to
link the executables as part of the default `make all` target.
Since linking the fuzzer executables without a fuzzing engine does not
require a C++ compiler, we can change the FUZZ_PROGRAMS build rule to
use $(CC) by default. This avoids compiler mis-match issues when
overriding $(CC) but not $(CXX). When we *do* want to actually link with
a fuzzing engine, we can set $(FUZZ_CXX). The build instructions in the
CI fuzz-smoke-test job and in the Makefile comment have been updated
accordingly.
While we're at it, we can consolidate some of the fuzzer build
instructions into one location in the Makefile.

In https://github.com/microsoft/git/issues/623, it was reported that
maintenance stops on a missing repository, omitting the remaining
repositories that were scheduled for maintenance.
This is undesirable, as it should be a best effort type of operation.
It should still fail due to the missing repository, of course, but not
leave the non-missing repositories in unmaintained shapes.
Let's use `for-each-repo`'s shiny new `--keep-going` option that we just
introduced for that very purpose.
This change will be picked up when running `git maintenance start`,
which is run implicitly by `scalar reconfigure`.

In https://github.com/microsoft/git/issues/623, it was reported that
the regularly scheduled maintenance stops if one repo in the middle of
the list was found to be missing.
This is undesirable, and points out a gap in the design of `git
for-each-repo`: We need a mode where that command does not stop on an
error, but continues to try running the specified command with the other
repositories.
Imitating the `--keep-going` option of GNU make, this commit teaches
`for-each-repo` the same trick: to continue with the operation on all
the remaining repositories in case there was a problem with one
repository, still setting the exit code to indicate an error occurred.

In the previous step, the "--rfc" option of "format-patch" learned
to take an optional string value to prepend to the subject prefix,
so that --rfc=WIP can give "[WIP PATCH]".
There may be cases in which the extra string wants to come after the
subject prefix. Extend the mechanism to allow "--rfc=-(WIP)" [*] to
signal that the extra string is to be appended instead of getting
prepended, resulting in "[PATCH (WIP)]".
In the documentation, discourage (ab)using "--rfc=-RFC" to say
"[PATCH RFC]" just to be different, when "[RFC PATCH]" is the norm.
[Footnote]
* The syntax takes inspiration from Perl's open syntax that opens
pipes "open fh, '|-', 'cmd'", where the dash signals "the other
stuff comes here".

With the "--rfc" option, we can tweak the "[PATCH]" (or whatever
string specified with the "--subject-prefix" option, instead of
"PATCH") that we prefix the title of the commit with into "[RFC
PATCH]", but some projects may want "[rfc PATCH]". Adding a new
option, e.g., "--rfc-lowercase", to support such need every time
somebody wants to use different strings would lead to insanity of
accumulating unbounded number of such options.
Allow an optional value specified for the option, so that users can
use "--rfc=rfc" (think of "--rfc" without value as a short-hand for
"--rfc=RFC") if they wanted to.
This can of course be (ab)used to make the prefix "[WIP PATCH]" by
passing "--rfc=WIP". Passing an empty string, i.e., "--rfc=", is
the same as "--no-rfc" to override an option given earlier on the
same command line.

"git stash --staged" errors out when given binary files, after saving the
stash.
This behaviour dates back to the addition of the feature in 41a28eb6c1
(stash: implement '--staged' option for 'push' and 'save', 2021-10-18).
Adding the "--binary" option of "diff-tree" fixes this. The "diff-tree" call
in stash_patch() also omits "--binary", but that is fine since binary files
cannot be selected interactively.

strbuf_addf() has been reporting a negative return value of vsnprintf(3)
as a bug since f141bd804d (Handle broken vsnprintf implementations in
strbuf, 2007-11-13). Other functions copied that behavior:
7b03c89ebd (add xsnprintf helper function, 2015-09-24)
5ef264dbdb (strbuf.c: add `strbuf_insertf()` and `strbuf_vinsertf()`, 2019-02-25)
8d25663d70 (mem-pool: add mem_pool_strfmt(), 2024-02-25)
However, vsnprintf(3) can legitimately return a negative value if the
formatted output would be longer than INT_MAX. Stop accusing it of
being broken and just report the fact that formatting failed.

not installed as part of "git" toolset. This also puts the script on

When rebasing with "--signoff" the commit created by "rebase --continue"
after resolving conflicts or editing a commit fails to add the
"Signed-off-by:" trailer. This happens because the message from the
original commit is reused instead of the one that would have been used
if the sequencer had not stopped for the user interaction. The correct
message is stored in ctx->message and so with a couple of exceptions
this is written to rebase_path_message() when stopping for user
interaction instead. The exceptions are (i) "fixup" and "squash"
commands where the file is written by error_failed_squash() and (ii)
"edit" commands that are fast-forwarded where the original message is
still reused. The latter is safe because "--signoff" will never
fast-forward.
Note this introduces a change in behavior as the message file now
contains conflict comments. This is safe because commit_staged_changes()
passes an explicit cleanup flag when not editing the message and when
the message is being edited it will be cleaned up automatically. This
means user now sees the same message comments in editor with "rebase
--continue" as they would if they ran "git commit" themselves before
continuing the rebase. It also matches the behavior of "git
cherry-pick", "git merge" etc. which all list the files with merge
conflicts.
The tests are extended to check that all commits made after continuing a
rebase have a "Signed-off-by:" trailer. Sadly there are a couple of
leaks in apply.c which I've not been able to track down that mean this
test file is no-longer leak free when testing "git rebase --apply
--signoff" with conflicts.

Add an strbuf to "struct replay_ctx" to hold the current commit
message. This does not change the behavior but it will allow us to fix a
bug with "git rebase --signoff" in the next commit. A future patch
series will use the changes here to avoid writing the commit message to
disc unless there are conflicts or the commit is being reworded.
The changes in do_pick_commit() are a mechanical replacement of "msgbuf"
with "ctx->message". In do_merge() the code to write commit message to
disc is factored out of the conditional now that both branches store the
message in the same buffer.

"struct replay_opts" has a number of fields that are for internal
use. While they are marked as private having them in a public struct is
a distraction for callers and means that every time the internal details
are changed we have to recompile all the files that include sequencer.h
even though the public API is unchanged. This commit starts the process
of removing the private fields by adding an opaque pointer to a "struct
replay_ctx" to "struct replay_opts" and moving the "reflog_message"

The sequencer currently updates the state files on disc each time it
processes a command in the todo list. This is an artifact of the
scripted implementation and makes the code hard to reason about as it is
not possible to get a complete view of the state in memory. In the
future we will add new members to "struct replay_ctx" to remedy this and
avoid writing state to disc unless the sequencer stops for user
interaction.

sequencer_post_commit_cleanup() initializes an instance of "struct
replay_opts" but does not call replay_opts_release(). Currently this
does not leak memory because the code paths called don't allocate any of
the struct members. That will change in the next commit so add call to
replay_opts_release() to prevent a memory leak in "git commit" that
breaks all of the leak free tests.

We observed a series of clone failures arose in a specific set of
repositories after we fully enabled the MIDX bitmap feature within our
Codebase service. These failures were accompanied with error messages
such as:
Cloning into bare repository 'clone.git'...
remote: Enumerating objects: 8, done.
remote: Total 8 (delta 0), reused 0 (delta 0), pack-reused 8 (from 1)
Receiving objects: 100% (8/8), done.
fatal: did not receive expected object ...
fatal: fetch-pack: invalid index-pack output
Temporarily disabling the MIDX feature eliminated the reported issues.
After some investigation we found that all repositories experiencing
failures contain replace references, which seem to be improperly
acknowledged by the MIDX bitmap generation logic.
A more thorough explanation about the root cause from Taylor Blau says:
Indeed, the pack-bitmap-write machinery does not itself call
disable_replace_refs(). So when it generates a reachability bitmap, it
is doing so with the replace refs in mind. You can see that this is
indeed the cause of the problem by looking at the output of an
instrumented version of Git that indicates what bits are being set
during the bitmap generation phase.
With replace refs (incorrectly) enabled, we get:
[2, 4, 6, 8, 13, 3, 6, 7, 3, 4, 6, 8]
and doing the same after calling disable_replace_refs(), we instead get:
[2, 5, 6, 13, 3, 6, 7, 3, 4, 6, 8]
Single pack bitmaps are unaffected by this issue because we generate
them from within pack-objects, which does call disable_replace_refs().
This patch updates the MIDX logic to disable replace objects within the
multi-pack-index builtin, and a test showing a clone (which would fail
with MIDX bitmap) is added to demonstrate the bug.

In 850b6edefa (auto-gc: extract a reusable helper from "git fetch",
2020-05-06), we have introduced a helper function `run_auto_gc()` that
kicks off `git gc --auto`. The intent of this function was to pass down
the "--quiet" flag to git-gc(1) as required without duplicating this at
all callsites. In 7c3e9e8cfb (auto-gc: pass --quiet down from am,
commit, merge and rebase, 2020-05-06) we then converted callsites that
need to pass down this flag to use the new helper function. This has the
notable omission of git-receive-pack(1), which is the only remaining
user of `git gc --auto` that sets up the proccess manually. This is
probably because it unconditionally passes down the `--quiet` flag and
thus didn't benefit much from the new helper function.
In a95ce12430 (maintenance: replace run_auto_gc(), 2020-09-17) we then
replaced `run_auto_gc()` with `run_auto_maintenance()` which invokes
git-maintenance(1) instead of git-gc(1). This command is the modern
replacement for git-gc(1) and is both more thorough and also more
flexible because administrators can configure which tasks exactly to run
during maintenance.
But due to git-receive-pack(1) not using `run_auto_gc()` in the first
place it did not get converted to use git-maintenance(1) like we do
everywhere else now. Address this oversight and start to use the newly
introduced function `prepare_auto_maintenance()`. This will also make it
easier for us to adapt this code together with all the other callsites
that invoke auto-maintenance in the future.
This removes the last internal user of `git gc --auto`.

The `run_auto_maintenance()` function is responsible for spawning a new
`git maintenance run --auto` process. To do so, it sets up the `sturct
child_process` and then runs it by executing `run_command()` directly.
This is rather inflexible in case callers want to modify the child
process somewhat, e.g. to redirect stderr or stdout.
Introduce a new `prepare_auto_maintenance()` function to plug this gap.

When rerere handles a conflict with an unmatched opening conflict marker
in a file with other conflicts, it will fail create a preimage and also
fail allocate the status member of struct rerere_dir. Currently the
status member is allocated after the error handling. This will lead to a
SEGFAULT when the status member is accessed during cleanup of the failed
parse.
Additionally, in subsequent executions of rerere, after removing the
MERGE_RR.lock manually, rerere crashes for a similar reason. MERGE_RR
points to a conflict id that has no preimage, therefore the status
member is not allocated and a SEGFAULT happens when trying to check if a
preimage exists.
Solve this by making sure the status field is allocated correctly and add
tests to prevent the bug from reoccurring.
This does not fix the root cause, failing to parse stray conflict
markers, but I don't think we can do much better than recognizing it,
printing an error, and moving on gracefully.

In 0fea6b73f1 (Merge branch 'tb/multi-pack-verbatim-reuse', 2024-01-12)
we have introduced multi-pack verbatim reuse of objects. This series has
introduced a new BTMP chunk, which encodes information about bitmapped
objects in the multi-pack index. Starting with dab60934e3 (pack-bitmap:
pass `bitmapped_pack` struct to pack-reuse functions, 2023-12-14) we use
this information to figure out objects which we can reuse from each of
the packfiles.
One thing that we glossed over though is backwards compatibility with
repositories that do not yet have BTMP chunks in their multi-pack index.
In that case, `nth_bitmapped_pack()` would return an error, which causes
us to emit a warning followed by another error message. These warnings
are visible to users that fetch from a repository:
```
$ git fetch
...
remote: error: MIDX does not contain the BTMP chunk
remote: warning: unable to load pack: 'pack-f6bb7bd71d345ea9fe604b60cab9ba9ece54ffbe.idx', disabling pack-reuse
remote: Enumerating objects: 40, done.
remote: Counting objects: 100% (40/40), done.
remote: Compressing objects: 100% (39/39), done.
remote: Total 40 (delta 5), reused 0 (delta 0), pack-reused 0 (from 0)
...
```
While the fetch succeeds the user is left wondering what they did wrong.
Furthermore, as visible both from the warning and from the reuse stats,
pack-reuse is completely disabled in such repositories.
What is quite interesting is that this issue can even be triggered in
case `pack.allowPackReuse=single` is set, which is the default value.
One could have expected that in this case we fall back to the old logic,
which is to use the preferred packfile without consulting BTMP chunks at
all. But either we fail with the above error in case they are missing,
or we use the first pack in the multi-pack-index. The former case
disables pack-reuse altogether, whereas the latter case may result in
reusing objects from a suboptimal packfile.
Fix this issue by partially reverting the logic back to what we had
before this patch series landed. Namely, in the case where we have no
BTMP chunks or when `pack.allowPackReuse=single` are set, we use the
preferred pack instead of consulting the BTMP chunks.

When seeking a reftable record in a block we need to position the
iterator _before_ the sought-after record so that the next call to
`block_iter_next()` would yield that record. To achieve this, the loop
that performs the linear seeks to restore the previous position once it
has found the record.
This is done by advancing two `block_iter`s: one to check whether the
next record is our sought-after record, and one that we update after
every iteration. This of course involves quite a lot of copying and also
leads to needless memory allocations.
Refactor the code to get rid of the `next` iterator and the copying this
involves. Instead, we can restore the previous offset such that the call
to `next` will return the correct record.
Next to being simpler conceptually this also leads to a nice speedup.

When calling `inflateInit()` and `inflate()`, the zlib library will
allocate several data structures for the underlying `zstream` to keep
track of various information. Thus, when inflating repeatedly, it is
possible to optimize memory allocation patterns by reusing the `zstream`
and then calling `inflateReset()` on it to prepare it for the next chunk
of data to inflate.
This is exactly what the reftable code is doing: when iterating through
reflogs we need to potentially inflate many log blocks, but we discard
the `zstream` every single time. Instead, as we reuse the `block_reader`
for each of the blocks anyway, we can initialize the `zstream` once and
then reuse it for subsequent inflations.
Refactor the code to do so, which leads to a significant reduction in
the number of allocations. The following measurements were done when
iterating through 1 million reflog entries. Before:
HEAP SUMMARY:

The reftable format stores log blocks in a compressed format. Thus,
whenever we want to read such a block we first need to decompress it.
This is done by calling the convenience function `uncompress2()` of the
zlib library, which is a simple wrapper that manages the lifecycle of
the `zstream` structure for us.
While nice for one-off inflation of data, when iterating through reflogs
we will likely end up inflating many such log blocks. This requires us
to reallocate the state of the `zstream` every single time, which adds
up over time. It would thus be great to reuse the `zstream` instead of
discarding it after every inflation.
Open-code the call to `uncompress2()` such that we can start reusing the
`zstream` in the subsequent commit. Note that our open-coded variant is
different from `uncompress2()` in two ways:
- We do not loop around `inflate()` until we have processed all input.
As our input is limited by the maximum block size, which is 16MB, we
should not hit limits of `inflate()`.
- We use `Z_FINISH` instead of `Z_NO_FLUSH`. Quoting the `inflate()`
documentation: "inflate() should normally be called until it returns
Z_STREAM_END or an error. However if all decompression is to be
performed in a single step (a single call of inflate), the parameter
flush should be set to Z_FINISH."
Furthermore, "Z_FINISH also informs inflate to not maintain a
sliding window if the stream completes, which reduces inflate's
memory footprint."
Other than that this commit is expected to be functionally equivalent
and does not yet reuse the `zstream`.

The reftable backend stores reflog entries in a compressed format and
thus needs to uncompress blocks before one can read records from it.
For each reflog block we thus have to allocate an array that we can
decompress the block contents into. This block is being discarded
whenever the table iterator moves to the next block. Consequently, we
reallocate a new array on every block, which is quite wasteful.
Refactor the code to reuse the uncompressed block data when moving the
block reader to a new block. This significantly reduces the number of
allocations when iterating through many compressed blocks. The following
measurements are done with `git reflog list` when listing 100k reflogs.

The table iterator has to iterate towards the next block once it has
yielded all records of the current block. This is done by creating a new
table iterator, initializing it to the next block, releasing the old
iterator and then copying over the data.
Refactor the code to instead advance the table iterator in place. This
is simpler and unlocks some optimizations in subsequent patches. Also,
it allows us to avoid some allocations.

The table iterator allows the caller to iterate through all records in a
reftable table. To do so it iterates through all blocks of the desired
type one by one, where for each block it creates a new block iterator
and yields all its entries.
One of the things that is somewhat confusing in this context is who owns
the block reader that is being used to read the blocks and pass them to
the block iterator. Intuitively, as the table iterator is responsible
for iterating through the blocks, one would assume that this iterator is
also responsible for managing the lifecycle of the reader. And while it
somewhat is, the block reader is ultimately stored inside of the block
iterator.
Refactor the code such that the block reader is instead fully managed by
the table iterator. Instead of passing the reader to the block iterator,
we now only end up passing the block data to it. Despite clearing up the
lifecycle of the reader, it will also allow for better reuse of the
reader in subsequent patches.
The following benchmark prints a single matching ref out of 1 million
refs. Before:
HEAP SUMMARY:

total heap usage: 6,607 allocs, 6,482 frees, 509,635 bytes allocated

HEAP SUMMARY:

total heap usage: 7,235 allocs, 7,110 frees, 301,481 bytes allocated
Note that while there are more allocation and free calls now, the
overall number of bytes allocated is significantly lower. The number of
allocations will be reduced significantly by the next patch though.

"\000". Forbid it so it isn't truncated.
fast-import still has other issues with NUL, but those will be addressed
later.

It describes what characters cannot be in an unquoted path, but not
their semantics. Reframe it as a definition of unquoted paths. From the
perspective of the parser, whether it starts with `"` is what defines
whether it will parse it as quoted or unquoted.
The restrictions on characters in unquoted paths (with starting-", LF,
and spaces) are explained in the quoted paragraph. Move it to the
unquoted paragraph and reword.
The restriction that the source paths of filecopy and filerename cannot
contain SP is only stated in their respective sections. Restate it in
the <path> section.

The strbuf in `note_change_n` is to copy the remainder of `p` before
potentially invalidating it when reading the next line. However, `p` is
not used after that point. It has been unused since the function was
created in a8dd2e7d2b (fast-import: Add support for importing commit
notes, 2009-10-09) and looks to be a fossil from adapting
`file_change_m`. Remove it.

Ever since filerename was added in f39a946a1f (Support wholesale
directory renames in fast-import, 2007-07-09) and filecopy in b6f3481bb4
(Teach fast-import to recursively copy files/directories, 2007-07-15),
both have produced an error when the destination path is empty. Later,
when support for targeting the root directory with an empty string was
added in 2794ad5244 (fast-import: Allow filemodify to set the root,
2010-10-10), this had the effect of allowing the quoted empty string
(`""`), but forbidding its unquoted variant (``). This seems to have
been intended as simple data validation for parsing two paths, rather
than a syntax restriction, because it was not extended to the other
operations.
All other occurrences of paths (in filemodify, filedelete, the source of
filecopy and filerename, and ls) allow both.
For most of this feature's lifetime, the documentation has not
prescribed the use of quoted empty strings. In e5959106d6
(Documentation/fast-import: put explanation of M 040000 <dataref> "" in
context, 2011-01-15), its documentation was changed from “`<path>` may
also be an empty string (`""`) to specify the root of the tree” to “The
root of the tree can be represented by an empty string as `<path>`”.
Thus, we should assume that some front-ends have depended on this
behavior.
Remove this restriction for the destination paths of filecopy and
filerename and change tests targeting the root to test `""` and ``.

Previously, one case would not write the path to the strbuf: when the
path is unquoted and at the end of the string. It was essentially
copy-on-write. However, with the logic simplification of the previous
commit, this case was eliminated and the strbuf is always populated.
Directly use the strbufs now instead of an alias.
Since this already changes all the lines that use the strbufs, rename
them from `uq` to be more descriptive. That they are unquoted is not
their most important property, so name them after what they carry.
Additionally, `file_change_m` no longer needs to copy the path before
reading inline data.

Path parsing in fast-import is inconsistent and many unquoting errors
are suppressed or not checked.
<path> appears in the grammar in these places:
filemodify ::= 'M' SP <mode> (<dataref> | 'inline') SP <path> LF
filedelete ::= 'D' SP <path> LF
filecopy ::= 'C' SP <path> SP <path> LF
filerename ::= 'R' SP <path> SP <path> LF
ls ::= 'ls' SP <dataref> SP <path> LF
ls-commit ::= 'ls' SP <path> LF
and fast-import.c parses them in five different ways:
1. For filemodify and filedelete:
Try to unquote <path>. If it unquotes without errors, use the
unquoted version; otherwise, treat it as literal bytes to the end of
the line (including any number of SP).
2. For filecopy (source) and filerename (source):
Try to unquote <path>. If it unquotes without errors, use the
unquoted version; otherwise, treat it as literal bytes up to, but not
including, the next SP.
3. For filecopy (dest) and filerename (dest):
Like 1., but an unquoted empty string is forbidden.
4. For ls:
If <path> starts with `"`, unquote it and report parse errors;
otherwise, treat it as literal bytes to the end of the line
(including any number of SP).
5. For ls-commit:
Unquote <path> and report parse errors.
(It must start with `"` to disambiguate from ls.)
In the first three, any errors from trying to unquote a string are
suppressed, so a quoted string that contains invalid escapes would be
interpreted as literal bytes. For example, `"\xff"` would fail to
unquote (because hex escapes are not supported), and it would instead be
interpreted as the byte sequence '"', '\\', 'x', 'f', 'f', '"', which is
certainly not intended. Some front-ends erroneously use their language's
standard quoting routine instead of matching Git's, which could silently
introduce escapes that would be incorrectly parsed due to this and lead
to data corruption.
The documentation states “To use a source path that contains SP the path
must be quoted.”, so it is expected that some implementations depend on
spaces being allowed in paths in the final position. Thus we have two
documented ways to parse paths, so simplify the implementation to that.
Now we have:
1. `parse_path_eol` for filemodify, filedelete, filecopy (dest),
filerename (dest), ls, and ls-commit:
If <path> starts with `"`, unquote it and report parse errors;
otherwise, treat it as literal bytes to the end of the line
(including any number of SP).
2. `parse_path_space` for filecopy (source) and filerename (source):
If <path> starts with `"`, unquote it and report parse errors;
otherwise, treat it as literal bytes up to, but not including, the
next SP. It must be followed by SP.
There remain two special cases: The dest <path> in filecopy and rename
cannot be an unquoted empty string (this will be addressed subsequently)
and <path> in ls-commit must be quoted to disambiguate it from ls.

CST6CDT and the like are POSIX timezone, with no rule for transition.
And POSIX doesn't enforce how to interpret the rule if it's omitted.
Some libc (e.g. glibc) resorted back to IANA (formerly Olson) db rules
for those timezones. Some libc (e.g. FreeBSD) uses a fixed rule.
Other libc (e.g. musl) interpret that as no transition at all [1].
In addition, distributions (notoriously Debian-derived, which uses IANA
db for CST6CDT and the like) started to split "legacy" timezones
like CST6CDT, EST5EDT into `tzdata-legacy', which will not be installed
by default [2].
In those cases, t9604 will run into failure.
Let's switch to POSIX timezone with rules to change timezone.

The tests for git-pack-refs(1) with the `core.sharedRepository` config
execute git-pack-refs(1) outside of the shell that has the expected
umask set. This is wrong because we want to test the behaviour of that
command with different umasks. The issue went unnoticed because most
distributions have a default umask of 0022, and we only ever test with
`--shared=true`, which re-adds the group write bit.
Fix the issue by moving git-pack-refs(1) into the umask'd shell and add
a bunch of test cases that exercise behaviour more thoroughly.
Note that we drop the check for whether `core.sharedRepository` was set
to the correct value to make the test setup a bit easier. We should be
able to rely on git-init(1) doing its thing correctly. Furthermore, to
help readability, we convert tests that pass `--shared=true` to instead
pass the equivalent `--shared=group`.

In GNU Make commit 07fcee35 ([SV 64815] Recipe lines cannot contain
conditional statements, 2023-05-22) and following, conditional
statements may no longer be preceded by a tab character (which Make
refers to as the recipe prefix).
There are a handful of spots in our various Makefile(s) which will break
in a future release of Make containing 07fcee35. For instance, trying to
compile the pre-image of this patch with the tip of make.git results in
the following:
$ make -v | head -1 && make
GNU Make 4.4.90
config.mak.uname:842: *** missing 'endif'. Stop.
The kernel addressed this issue in 82175d1f9430 (kbuild: Replace tabs
with spaces when followed by conditionals, 2024-01-28). Address the
issues in Git's tree by applying the same strategy.
When a conditional word (ifeq, ifneq, ifdef, etc.) is preceded by one or
more tab characters, replace each tab character with 8 space characters
with the following:
find . -type f -not -path './.git/*' -name Makefile -or -name '*.mak' |
xargs perl -i -pe '
s/(\t+)(ifn?eq|ifn?def|else|endif)/" " x (length($1) * 8) . $2/ge unless /\\$/
'
The "unless /\\$/" removes any false-positives (like "\telse \"
appearing within a shell script as part of a recipe).
After doing so, Git compiles on newer versions of Make:
$ make -v | head -1 && make
GNU Make 4.4.90
GIT_VERSION = 2.44.0.414.gfac1dc44ca9

The excludes_file variable is marked "const char *", but all the
assignments to it are made with a piece of memory allocated just
for it, and the variable is responsible for owning it.
When "core.excludesfile" is read, the code just lost the previous
value, leaking memory. Plug it.
The real problem is that the variable is mistyped; our convention
is to never make a variable that owns the piece of memory pointed
by it as "const". Fixing that would reduce the chance of this kind
of bug happening, and also would make it unnecessary to cast the
constness away while free()ing it, but that would be a much larger
follow-up effort.

To reduce the number of on-disk reftables, compaction is performed.
Contiguous tables with the same binary log value of size are grouped
into segments. The segment that has both the lowest binary log value and
contains more than one table is set as the starting point when
identifying the compaction segment.
Since segments containing a single table are not initially considered
for compaction, if the table appended to the list does not match the
previous table log value, no compaction occurs for the new table. It is
therefore possible for unbounded growth of the table list. This can be
demonstrated by repeating the following sequence:
git branch -f foo
git branch -d foo
Each operation results in a new table being written with no compaction
occurring until a separate operation produces a table matching the
previous table log value.
Instead, to avoid unbounded growth of the table list, the compaction
strategy is updated to ensure tables follow a geometric sequence after
each operation by individually evaluating each table in reverse index
order. This strategy results in a much simpler and more robust algorithm
compared to the previous one while also maintaining a minimal ordered
set of tables on-disk.
When creating 10 thousand references, the new strategy has no
performance impact:
Benchmark 1: update-ref: create refs sequentially (revision = HEAD~)
Time (mean ± σ): 26.516 s ± 0.047 s [User: 17.864 s, System: 8.491 s]
Range (min … max): 26.447 s … 26.569 s 10 runs
Benchmark 2: update-ref: create refs sequentially (revision = HEAD)
Time (mean ± σ): 26.417 s ± 0.028 s [User: 17.738 s, System: 8.500 s]
Range (min … max): 26.366 s … 26.444 s 10 runs
Summary
update-ref: create refs sequentially (revision = HEAD) ran
1.00 ± 0.00 times faster than update-ref: create refs sequentially (revision = HEAD~)
Some tests in `t0610-reftable-basics.sh` assert the on-disk state of
tables and are therefore updated to specify the correct new table count.
Since compaction is more aggressive in ensuring tables maintain a
geometric sequence, the expected table count is reduced in these tests.
In `reftable/stack_test.c` tests related to `sizes_to_segments()` are
removed because the function is no longer needed. Also, the
`test_suggest_compaction_segment()` test is updated to better showcase
and reflect the new geometric compaction behavior.

2013-07-08) to add a rule to t/check-non-portable-shell.pl script to
reject
export VAR=VAL
and suggest us to instead write it as two statements, i.e.,
VAR=VAL
export VAR
This however was not spelled out in the CodingGuidelines document.
We may want to re-evaluate the rule since it is from ages ago, but
for now, let's make the written rule and what the automation
enforces consistent.

- Support multi-line methods by not requiring closing parenthesis.
- Support multiple generics (comma was missing before).
- Add missing `foreach`, `lock` and `fixed` keywords to skip over.
- Remove `instanceof` keyword, which isn't C#.
- Also detect non-method keywords not positioned at the start of a line.
- Added tests; none existed before.
The overall strategy is to focus more on what isn't expected for
method/property definitions, instead of what is, but is fully optional.

date_mode_from_type() modifies a static variable and returns a pointer
to it. This is not thread-safe. Most callers of date_mode_from_type()
use it via the macro DATE_MODE and pass its result on to functions like
show_date(), which take a const pointer and don't modify the struct.
Avoid the static storage by putting the variable on the stack and
returning the whole struct date_mode. Change functions that take a
constant pointer to expect the whole struct instead.
Reduce the cost of passing struct date_mode around on 64-bit systems
by reordering its members to close the hole between the 32-bit wide
.type and the 64-bit aligned .strftime_fmt as well as the alignment
hole at the end. sizeof reports 24 before and 16 with this change
on x64. Keep .type at the top to still allow initialization without
designator -- though that's only done in a single location, in
builtin/blame.c.

vreportf(), which is used e.g. by die() and warning() by default, calls
vsnprintf(3) to format the message to report. If that call fails, it
only prints the prefix, e.g. "fatal: " or "warning: ". This at least
informs users that they were supposed to get a message and reveals its
severity, but leaves them wondering what it may have been about.
Here's an example where vreportf() tries to print a message with a 2GB
string, which is too much for vsnprintf(3):
$ perl -le 'print "create refs/heads/", "a"x2**31' | git update-ref --stdin
fatal:
At least report the formatting error along with the offending message
(unformatted) to indicate why that message is empty. Use fprintf(3)
instead of error() to get the message out directly and avoid recursing
back into vreportf().
With this patch we get:
$ perl -le 'print "create refs/heads/", "a"x2**31' | git update-ref --stdin
error: unable to format message: invalid ref format: %s
fatal:
... which allows users to at least get an idea of what went wrong.

As of curl 7.66.0, we don't need to manually specify a "chunked"
Transfer-Encoding header. Instead, modern curl deduces the need for it
in a POST that has a POSTFIELDSIZE of -1 and uses READFUNCTION rather
than POSTFIELDS.
That version is recent enough that we can't just drop the header; we
need to do so conditionally. Since it's only a single line, it seems
like the simplest thing would just be to keep setting it unconditionally
(after all, the #ifdefs are much longer than the actual code). But
there's another wrinkle: HTTP/2.
Curl may choose to use HTTP/2 under the hood if the server supports it.
And in that protocol, we do not use the chunked encoding for streaming
at all. Most versions of curl handle this just fine by recognizing and
removing the header. But there's a regression in curl 8.7.0 and 8.7.1
where it doesn't, and large requests over HTTP/2 are broken (which t5559
notices). That regression has since been fixed upstream, but not yet
released.
Make the setting of this header conditional, which will let Git work
even with those buggy curl versions. And as a bonus, it serves as a
reminder that we can eventually clean up the code as we bump the
supported curl versions.

When parsing config keys, the normal pattern is to return 0 after
completing the logic for a specific config key, since no other key will
match. One instance, for "submodule.recurse", was missing this case in
builtin/fetch.c.
This is a very minor change, and will have minimal impact to
performance. This particular block was edited recently in 56e8bb4fb4
(fetch: use `fetch_config` to store "fetch.recurseSubmodules" value,
2023-05-17), which led to some hesitation that perhaps this omission was
on purpose.
However, no later cases within git_fetch_config() will match the key if
equal to "submodule.recurse" and neither will any key matches within the
catch-all git_default_config().

PATH_MAX is not always a hard limit and 'path' in create_one_file()
could be longer -- it's taken from the patch file and allocated
dynamically. Allocate the name of the temporary file on the heap as
well instead of using a fixed-size buffer to avoid that arbitrary limit.
Resist the temptation of using the more convenient mkpath() to avoid
introducing a dependency on a static variable deep inside the apply
machinery.
Take care to work around (arguably buggy) implementations of free(3)
that modify errno, by calling it only after using the errno value.

When passing untracked path with -u option, it silently succeeds.
There is no error message and the exit code is zero. This is
inconsistent with other instances of git commands where the expected
argument is a known path. In those other instances, we error out when
the path is not known.
Fix this by passing a character array to add_files_to_cache() to
collect the pathspec matching information and report the error if a
pathspec does not match any cache entry. Also add a testcase to cover
this scenario.

When we provide a pathspec which does not match any tracked path
alongside --include, we do not error like without --include. If there
is something staged, it will commit the staged changes and ignore the
pathspec which does not match any tracked path. And if nothing is
staged, it will print the status. Exit code is 0 in both cases (unlike
without --include). This is also described in the TODO comment before
the relevant testcase.
Fix this by passing a character array to add_files_to_cache() to
collect the pathspec matching information and error out if the given
path is untracked. Also, amend the testcase to check for the error
message and remove the TODO comment.

Unlike "git add" and other end-user facing commands, where it is
diagnosed as an error to give a pathspec with an element that does
not match any path, the diff machinery does not care if some
elements of the pathspec do not match. Given that the diff
machinery is heavily used in pathspec-limited "git log" machinery,
and it is common for a path to come and go while traversing the
project history, this is usually a good thing.
However, in some cases we would want to know if all the pathspec
elements matched. For example, "git add -u <pathspec>" internally
uses the machinery used by "git diff-files" to decide contents from
what paths to add to the index, and as an end-user facing command,
"git add -u" would want to report an unmatched pathspec element.
Add a new .ps_matched member next to the .prune_data member in
"struct rev_info" so that we can optionally keep track of the use of
.prune_data pathspec elements that can be inspected by the caller.

Windows 10 build 17063 introduced support for unix sockets to Windows.
bb390b1 (git-compat-util: include declaration for unix sockets in
windows, 2021-09-14) introduced a way to build git with unix socket
support on Windows, but you still had to decide at build time which
Windows version the compiled executable was supposed to run on.
We can detect at runtime wether the operating system supports unix
sockets and act accordingly for all supported Windows versions.
This fixes https://github.com/git-for-windows/git/issues/3892
