Enable macOS build with sha1dc hash function.

fsmonitor OSX: compile with DC_SHA1=YesPlease
|
|
7b8cfe34 (Merge branch 'ed/fsmonitor-on-networked-macos',
2022-10-17) broke the build on macOS with sha1dc by bypassing our
hash abstraction (git_SHA_CTX etc.), but it wasn't caught before the
problematic topic was merged down to the 'master' branch. Nobody
was even compile testing with DC_SHA1 set, although it is the
recommended choice in these days for folks when they use SHA-1.
This was because the default for macOS uses Apple Common Crypto, and
both of the two CI jobs did not override the default. Tweak one of
them to use DC_SHA1 to improve the coverage.
We may want to give similar diversity for Linux jobs so that some of
them build with other implementations of SHA-1; they currently all
build and test with DC_SHA1 as that is the default on everywhere
other than macOS.
But let's start small to fill only the immediate need.

The current code is clean with these two sanitizers, and we would
like to keep it that way by running the checks for any new code.
The signal of "passed with asan, but not ubsan" (or vice versa) is
not that useful in practice, so it is tempting to run both santizers
in a single task, but it seems to take forever, so tentatively let's
try having two separate ones.

As suggested in
https://github.com/git-for-windows/git/issues/3966#issuecomment-1221264238,
t7112 can run for well over one hour, which seems to be the default
maximum run time at least when running CTest-based tests in Visual
Studio.
Let's increase the time-out as a stop gap to unblock developers wishing
to run Git's test suite in Visual Studio.
Note: The actual run time is highly dependent on the circumstances. For
example, in Git's CI runs, the Windows-based tests typically take a bit
over 5 minutes to run. CI runs have the added benefit that Windows
Defender (the common anti-malware scanner on Windows) is turned off,
something many developers are not at liberty to do on their work
stations. When Defender is turned on, even on this developer's high-end
Ryzen system, t7112 takes over 15 minutes to run.

In 7f5397a07c6c (cmake: support for testing git when building out of the
source tree, 2020-06-26), we implemented support for running Git's test
scripts even after building Git in a different directory than the source
directory.
The way we did this was to edit the file `t/test-lib.sh` to override
`GIT_BUILD_DIR` to point somewhere else than the parent of the `t/`
directory.
This is unideal because it always leaves a tracked file marked as
modified, and it is all too easy to commit that change by mistake.
Let's change the strategy by teaching `t/test-lib.sh` to detect the
presence of a file called `GIT-BUILD-DIR` in the source directory. If it
exists, the contents are interpreted as the location to the _actual_
build directory. We then write this file as part of the CTest
definition.
To support building Git via a regular `make` invocation after building
it using CMake, we ensure that the `GIT-BUILD-DIR` file is deleted (for
convenience, this is done as part of the Makefile rule that is already
run with every `make` invocation to ensure that `GIT-BUILD-OPTIONS` is
up to date).

In the interactive `add` operation, users can choose to jump to specific
hunks, and Git will present the hunk list in that case. To avoid showing
too many lines at once, only a maximum of 21 hunks are shown, skipping
the "mode change" pseudo hunk.
The comparison performed to skip the "mode change" pseudo hunk (if any)
compares a signed integer `i` to the unsigned value `mode_change` (which
can be 0 or 1 because it is a 1-bit type).
According to section 6.3.1.8 of the C99 standard (see e.g.
https://www.open-std.org/jtc1/sc22/WG14/www/docs/n1256.pdf), what should
happen is an automatic conversion of the "lesser" type to the "greater"
type, but since the types differ in signedness, it is ill-defined what
is the correct "usual arithmetic conversion".
Which means that Visual C's behavior can (and does) differ from GCC's:
When compiling Git using the latter, `add -p`'s `goto` command shows no
hunks by default because it casts a negative start offset to a pretty
large unsigned value, breaking the "goto hunk" test case in
`t3701-add-interactive.sh`.
Let's avoid that by converting the unsigned bit explicitly to a signed
integer.
Note: This is a long-standing bug in the Visual C build of Git, but it
has never been caught because t3701 is skipped when `NO_PERL` is set,
which is the case in the `vs-test` jobs of Git's CI runs.

When a test script fails in Git's test suite, the usual course of action
is to re-run it using options to increase the verbosity of the output,
e.g. `-v` and `-x`.
Like in Git's CI runs, when running the tests in Visual Studio via the
CTest route, it is cumbersome or at least requires a very unintuitive
approach to pass options to the test scripts: the CMakeLists.txt file
would have to be modified, passing the desired options to _all_ test
scripts, and then the CMake Cache would have to be reconfigured before
running the test in question individually. Unintuitive at best, and
opposite to the niceties IDE users expect.
So let's just pass those options by default: This will not clutter any
output window but the log that is written to a log file will have
information necessary to figure out test failures.
While at it, also imitate what the Windows jobs in Git's CI runs do to
accelerate running the test scripts: pass the `--no-bin-wrappers` and
`--no-chain-lint` options.
This makes the test runs noticeably faster because the `bin-wrappers/`
scripts as well as the `chain-lint` code make heavy use of POSIX shell
scripting, which is really, really slow on Windows due to the need to
emulate POSIX behavior via the MSYS2 runtime. In a test by Eric
Sunshine, it added two minutes (!) just to perform the chain-lint task.
The idea of adding a CMake config option (á la `GIT_TEST_OPTS`) was
considered during the development of this patch, but then dropped: such
a setting is global, across _all_ tests, where e.g. `--run=...` would
not make sense. Users wishing to override these new defaults are better
advised running the test script manually, in a Git Bash, with full
control over the command line.

As we'll address in subsequent commits the "DC_SHA1=YesPlease" is not
on by default on OSX, instead we use Apple Common Crypto's SHA-1
implementation.
In 6beb2688d33 (fsmonitor: relocate socket file if .git directory is
remote, 2022-10-04) the build was broken with "DC_SHA1=YesPlease" (and
probably other non-"APPLE_COMMON_CRYPTO" SHA-1 backends).
So let's extract the fix for this from [1] to get the build working
again with "DC_SHA1=YesPlease". In addition to the fix in [1] we also
need to replace "SHA_DIGEST_LENGTH" with "GIT_MAX_RAWSZ".

Compiling with -O2 can interact badly with LSan's leak-checker, causing
false positives. Imagine a simplified example like:
char *str = allocate_some_string();
if (some_func(str) < 0)
die("bad str");
free(str);
The compiler may eliminate "str" as a stack variable, and just leave it
in a register. The register is preserved through most of the function,
including across the call to some_func(), since we'd eventually need to
free it. But because die() is marked with NORETURN, the compiler knows
that it doesn't need to save registers, and just clobbers it.
When die() eventually exits, the leak-checker runs. It looks in
registers and on the stack for any reference to the memory allocated by
str (which would indicate that it's not leaked), but can't find one. So
it reports it as a leak.
Neither system is wrong, really. The C standard (mostly section 5.1.2.3)
defines an abstract machine, and compilers are allowed to modify the
program as long as the observable behavior of that abstract machine is
unchanged. Looking at random memory values on the stack is undefined
behavior, and not something that the optimizer needs to support. But
there really isn't any other way for a leak checker to work; it
inherently has to do undefined things like scouring memory for pointers.
So the two things are inherently at odds with each other. We can't fix
it by changing the code, because from the perspective of the program
running in an abstract machine, there is no leak.
This has caused real false positives in the past, like:
- https://lore.kernel.org/git/patch-v3-5.6-9a44204c4c9-20211022T175227Z-avarab@gmail.com/
- https://lore.kernel.org/git/Yy4eo6500C0ijhk+@coredump.intra.peff.net/
- https://lore.kernel.org/git/Y07yeEQu+C7AH7oN@nand.local/
This patch makes those go away by forcing -O0 when compiling with LSan.
There are a few ways we could do this:
- we could just teach the linux-leaks CI job to set -O0. That's the
smallest change, and means we wouldn't get spurious CI failures. But
it doesn't help people looking for leaks manually or in a specific
test (and because the problem depends on the vagaries of the
optimizer, investigating these can waste a lot of time in
head-scratching as the problem comes and goes)
- we default to -O2 in CFLAGS; we could pull this out to a separate
variable ("-O$(O)" or something) and modify "O" when LSan is in use.
This is the most flexible, in that you could still build with "make
O=2 SANITIZE=leak" if you really wanted to (say, for experimenting).
But it would also fail to kick in if the user defines their own
CFLAGS variable, which again leads to head-scratching.
- we can just stick -O0 into BASIC_CFLAGS when enabling LSan. Since
this comes after the user-provided CFLAGS, it will override any
previous -O setting found there. This is more foolproof, albeit less
flexible. If you want to experiment with an optimized leak-checking
build, you'll have to put "-O2 -fsanitize=leak" into CFLAGS
manually, rather than using our SANITIZE=leak Makefile magic.
Since the final one is the least likely to break in normal use, this
patch uses that approach.
The resulting build is a little slower, of course, but since LSan is
already about 2x slower than a regular build, another 10% slowdown isn't
that big a deal.

When attempting to initialize a repository object in an unsafe
directory, a syntax error is reported (Can't use string as a HASH ref
while strict refs in use). Fix this runtime error by adding the required
semicolon after the catch statement.
Without the semicolon, the result of the following line (i.e., the
result of Cwd::abs_path) is passed as the third argument to Error.pm's
catch function. That function expects that its third argument,
$clauses, is a hash reference, and trying to access a string as a hash
reference is a fatal error.

`git repack` supports a `--pack-kept-objects` flag which more or less
translates to whether or not we pass `--honor-pack-keep` down to `git
pack-objects` when assembling a new pack.
This behavior has existed since ee34a2bead (repack: add
`repack.packKeptObjects` config var, 2014-03-03). In that commit, the
documentation was extended to say:
[...] Note that we still do not delete `.keep` packs after
`pack-objects` finishes.
Unfortunately, this is not the case when `--pack-kept-objects` is
combined with a `--geometric` repack. When doing a geometric repack, we
include `.keep` packs when enumerating available packs only when
`pack_kept_objects` is set.
So this all works fine when `--no-pack-kept-objects` (or similar) is
given. Kept packs are excluded from the geometric roll-up, so when we go
to delete redundant packs (with `-d`), no `.keep` packs appear "below
the split" in our geometric progression.
But when `--pack-kept-objects` is given, things can go awry. Namely,
when a kept pack is included in the list of packs tracked by the
`pack_geometry` struct *and* part of the pack roll-up, we will delete
the `.keep` pack when we shouldn't.
Note that this *doesn't* result in object corruption, since the `.keep`
pack's objects are still present in the new pack. But the `.keep` pack
itself is removed, which violates our promise from back in ee34a2bead.
But there's more. Because `repack` computes the geometric roll-up
independently from selecting which packs belong in a MIDX (with
`--write-midx`), this can lead to odd behavior. Consider when a `.keep`
pack appears below the geometric split (ie., its objects will be part of
the new pack we generate).
We'll write a MIDX containing the new pack along with the existing
`.keep` pack. But because the `.keep` pack appears below the geometric
split line, we'll (incorrectly) try to remove it. While this doesn't
corrupt the repository, it does cause us to remove the MIDX we just
wrote, since removing that pack would invalidate the new MIDX.
Funny enough, this behavior became far less noticeable after e4d0c11c04
(repack: respect kept objects with '--write-midx -b', 2021-12-20), which
made `pack_kept_objects` be enabled by default only when we were writing
a non-MIDX bitmap.
But e4d0c11c04 didn't resolve this bug, it just made it harder to notice
unless callers explicitly passed `--pack-kept-objects`.
The solution is to avoid trying to remove `.keep` packs during
`--geometric` repacks, even when they appear below the geometric split
line, which is the approach this patch implements.

When we write a MIDX bitmap after repacking, it is possible that the
repository would be left in a state with both pack- and multi-pack
reachability bitmaps.
This can occur, for instance, if a pack that was kept (either by having
a .keep file, or during a geometric repack in which it is not rolled up)
has a bitmap file, and the repack wrote a multi-pack index and bitmap.
When loading a reachability bitmap for the repository, the multi-pack
one is always preferred, so the pack-based one is redundant. Let's
remove it unconditionally, even if '-d' isn't passed, since there is no
practical reason to keep both around. The patch below does just that.

We have a generic ll_merge_fn, but not every implementation needs every
parameter. In particular, neither binary nor ext merges care about names
(since they do not generate conflict markers), and most do not need to
look at the ll_merge_driver itself.
Ironically, neither ll_xdl_merge() nor ll_union_merge() needs to have
their driver parameter annotated (even though both are named
drv_unused!). This is because they may fall back to calling
ll_binary_merge() directly. And even though that function won't look at
it, we still pass it along, and hence it is "used" in the caller.
We could get away with passing NULL, but that's likely more confusing
and brittle than just passing along our own driver. And we have to keep
the driver parameter in all callbacks, since ll_ext_merge() uses it.

The parse-options callback for --again soaks up all remaining options by
manipulating the parse_opt_ctx's argc and argv fields. Even though it
has to look at both, the actual parsing happens via the do_reupdate()
helper, which only looks at the argv half (by passing it along to
parse_pathspec). So that helper doesn't need to see argc at all.
Note that the helper does look at "argv + 1" without confirming that
argc is greater than 0. We know this is correct because it is skipping
past the actual "--again" string, which will always be present. However,
to make what's going on more obvious, let's move that "+1" into the
caller, which has the matching "-1" when fixing up the ctx's argc/argv.

The module_list_compute() function takes an argc/argv pair, but never

for our purposes (we feed it to parse_pathspec(), which takes only the
array, not a count).
Note that one of the callers _looks_ like it would be buggy, but isn't:
we pass 0/NULL for argc/argv from module_foreach(), so finding the
terminating NULL in that argv naively would segfault. However,
parse_pathspec() is smart enough to interpret a bare NULL as an empty
argv.

The apply backend creates slightly different reflog messages to the
merge backend when starting or finishing a rebase and when picking
commits. These differences make it harder than it needs to be to parse
the reflog (I have a script that reads the finishing messages from
rebase and it is a pain to have to accommodate two different message
formats). While it is possible to determine the backend used for a
rebase from the reflog messages, the differences are not designed for
that purpose. c2417d3af7 (rebase: drop '-i' from the reflog for
interactive-based rebases, 2020-02-15) removed the clear distinction
between the reflog messages of the two backends without complaint.
As the merge backend is the default it is likely to be the format most
common in existing reflogs. For that reason the apply backend is changed
to format its reflog messages to match the merge backend as closely as
possible. Note that there is still a difference as when committing a
conflict resolution the apply backend will use "(pick)" rather than
"(continue)" because it is not currently possible to change the message
for a single commit.
In addition to c2417d3af7 we also changed the reflog messages in
68aa495b59 (rebase: implement --merge via the interactive machinery,
2018-12-11) and 2ac0d6273f (rebase: change the default backend from "am"
to "merge", 2020-02-15). This commit makes the same change to "git
rebase --apply" that 2ac0d6273f made to "git rebase" without any backend
specific options. As the messages are changed to use an existing format
any scripts that can parse the reflog messages of the default rebase
backend should be unaffected by this change.
There are existing tests for the messages from both backends which are
adjusted to ensure that they do not get out of sync in the future.

The reflog messages when finishing a rebase hard code "rebase" rather
than using GIT_REFLOG_ACTION.

The reflog message for every pick after running "rebase --skip" looks
like
rebase (skip) (pick): commit subject line
Fix this by not appending " (skip)" to the reflog action.

The reflog message for a conflict resolution committed by "rebase
--continue" looks like
rebase (continue): commit subject line
Unfortunately the reflog message each subsequent pick look like
rebase (continue) (pick): commit subject line
Fix this by setting the reflog message for "rebase --continue" in
sequencer_continue() so it does not affect subsequent commits. This
introduces a memory leak similar to the one leaking GIT_REFLOG_ACTION
in pick_commits(). Both of these will be fixed in a future series that
stops the sequencer calling setenv().
If we fail to commit the staged changes then we error out so
GIT_REFLOG_ACTION does not need to be reset in that case.
