Our current loose object format has a few problems. First, it is not
efficient: the list of object IDs is not sorted and even if it were,
there would not be an efficient way to look up objects in both
algorithms.
Second, we need to store mappings for things which are not technically
loose objects but are not packed objects, either, and so cannot be
stored in a pack index. These kinds of things include shallows, their
parents, and their trees, as well as submodules. Yet we also need to
implement a sensible way to store the kind of object so that we can
prune unneeded entries. For instance, if the user has updated the
shallows, we can remove the old values.
For these reasons, introduce a new binary object map format. The
careful reader will notice that it resembles very closely the pack index
v3 format. Add an in-memory object map as well, and allow writing to a
batched map, which can then be written later as one of the binary object
maps. Include several tests for round tripping and data lookup across
algorithms.
Note that the use of this code elsewhere in Git will involve some C code
and some C-compatible code in Rust that will be introduced in a future
commit. Thus, for example, we ignore the fact that if there is no
current batch and the caller asks for data to be written, this code does
nothing, mostly because this code also does not involve itself with
opening or manipulating files. The C code that we will add later will
implement this functionality at a higher level and take care of this,
since the code which is necessary for writing to the object store is
deeply involved with our C abstractions and it would require extensive
work (which would not be especially valuable at this point) to port
those to Rust.

In a future commit, we'll want to hash some data when dealing with an
object map. Let's make this easy by creating a structure to hash
objects and calling into the C functions as necessary to perform the
hashing. For now, we only implement safe hashing, but in the future we
could add unsafe hashing if we want. Implement Clone and Drop to
appropriately manage our memory. Additionally implement Write to make
it easy to use with other formats that implement this trait.
While we're at it, add some tests for the various hashing cases.

Cargo uses the build.rs script to determine how to compile and link a
binary. The only binary we're generating, however, is for our tests,
but in a future commit, we're going to link against libgit.a for some
functionality and we'll need to make sure the test binaries are
complete.
Add a build.rs file for this case and specify the files we're going to
be linking against. Because we cannot specify different dependencies
when building our static library versus our tests, update the Makefile
to specify these dependencies for our static library to avoid race
conditions during build.

When Cargo links binaries with MSVC, it uses the link.exe linker from
PATH to do so. However, when running under a shell from MSYS, such as
when building with the Git for Windows SDK, which we do in CI, the
/ming64/bin and /usr/bin entries are first in PATH. That means that the
Unix link binary shows up first, which obviously does not work for
linking binaries in any useful way.
To solve this problem, adjust PATH to place those binaries at the end of
the list instead of the beginning. This allows access to the normal
Unix tools, but link.exe will be the compiler's linker. Make sure to
export PATH explicitly: while this should be the default, it's more
robust to not rely on the shell operating in a certain way.
The reason this has not shown up before is that we typically link our
binaries from the C compiler. However, now that we're about to
introduce a Rust build script (build.rs file), Rust will end up linking
that script to further drive Cargo, in which case we'll invoke the
linker from it. There are other solutions, such as using LLD, but this
one is simple and reliable and is most likely to work with existing
systems.

Right now, users can internally access the contents of the ObjectID
struct, which can lead to data that is not valid, such as invalid
algorithms or non-zero-padded hash values. These can cause problems
down the line as we use them more.
Add a constructor for ObjectID that allows us to set these values and
also provide an accessor for the algorithm so that we can access it. In
addition, provide useful Display and Debug implementations that can
format our data in a useful way.

In C, it's easy for us to look up a hash algorithm structure by its
offset by simply indexing the hash_algos array. However, in Rust, we

the C structure from the offset and expose it in Rust.

This works very similarly to the existing one in C except that it
doesn't provide any functionality to hash an object. We don't currently
need that right now, but the use of those function pointers do make it
substantially more difficult to write a bit-for-bit identical structure
across the C/Rust interface, so omit them for now.
Instead of the more customary "&self", use "self", because the former is
the size of a pointer and the latter is the size of an integer on most
systems. Don't define an unknown value but use an Option for that
instead.

repository: require Rust support for interoperability
We'll be implementing some of our interoperability code, like the loose
object map, in Rust. While the code currently compiles with the old
loose object map format, which is written entirely in C, we'll soon
replace that with the Rust-based implementation.
Require the use of Rust for compatibility mode and die if it is not
supported. Because the repo argument is not used when Rust is missing,
cast it to void to silence the compiler warning, which we do not care
about.
Add a prerequisite in our tests, RUST, that checks if Rust functionality
is available and use it in the tests that handle interoperability.
This is technically a regression in functionality compared to our
existing state, but pack index v3 is not yet implemented and thus the
functionality is mostly quite broken, which is why we've recently marked
this functionality as experimental. We don't believe anyone is getting
useful use out of the interoperability code in its current state, so no
actual users should be negatively impacted by this change.

as their exit codes are suppressed inside echo command
substitution and being on the upstream side of pipes.
Instead of using here-doc to construct the pack
protocol that is directly sent to the
'git upload-pack' command being tested,
capture the outputs of the git commands upfront
and use the 'test-tool pkt-line pack'

and then feed it to the command.
This has a few advantages:
* Executing the git commands outside the here-doc
avoids suppressing their exit codes and makes
debugging easier.
* It removes the need to manually count and
manage pkt-line lengths to keep in line with
the v2 protocol, as the tool handles this internally.

remote: always allocate branch.push_tracking_ref
In branch_get_push(), we usually allocate a new string for the @{push}
ref, but will not do so in push.default=upstream mode, where we just
pass back the result of branch_get_upstream() directly.
This led to a hacky memory management scheme in e291c75a95 (remote.c:
add branch_get_push, 2015-05-21): we store the result in the
push_tracking_ref field of a "struct branch", under the assumption that
the branch struct will last until the end of the program. So even though
the struct doesn't know if it has an allocated string or not, it doesn't
matter because we hold on to it either way.
But that assumption was violated by f5ccb535cc (remote: fix leaking
config strings, 2024-08-22), which added a function to free branch
structs. Any struct which is fed to branch_release() is at risk of
leaking its push_tracking_ref member.
I don't think this can actually be triggered in practice. We rarely
actually free the branch structs, and we only fill in the
push_tracking_ref string lazily when it is needed. So triggering the
leak would require a code path that does both, and I couldn't find one.
Still, this is an ugly trap that may eventually spring on us. Since
there is only one code path in branch_get_push() that doesn't allocate,
let's just have it copy the string. And then we know that

Most of the code paths in branch_get_push_1() allocate a string for the

But there's one path that does leak: when we are in the "simple" push

@{upstream}. If it doesn't, we return an error, but forget to free the
@{push} value we computed.
Curiously, the existing tests don't trigger this with LSan, even though
they do exercise the code path. As far as I can tell, it should be
triggered via:
which will complain that the upstream ("not-foo") does not match the
push destination ("foo"). We do die() shortly after this, but not until
after returning from branch_get_push_1(), which is where the leak
happens.
So it seems like a false negative in LSan. However, I can trigger it
reliably by printing the @{push} value using for-each-ref. This takes a
little more setup (because we need "foo" to actually exist to iterate

config in t6300.

remote: drop const return of tracking_for_push_dest()
The string returned from tracking_for_push_dest() comes from
apply_refspec(), and thus is always an allocated string (or NULL). We
should return a non-const pointer so that the caller knows that
ownership of the string is being transferred.
This goes back to the function's origin in e291c75a95 (remote.c: add
branch_get_push, 2015-05-21). It never really mattered because our
return is just forwarded through branch_get_push_1(), which returns a
const string as part of an intentionally hacky memory management scheme
(see that commit for details).
As the first step of untangling that hackery, let's drop the extra const
from this helper function (and from the variables that store its
result). There should be no functional change (yet).

remote: return non-const pointer from error_buf()
We have an error_buf() helper that functions a bit like our error()
helper, but returns NULL instead of -1. Its return type is "const char
*", but this is overly restrictive. If we use the helper in a function
that returns non-const "char *", the compiler will complain about
the implicit cast from const to non-const.
Meanwhile, the const in the helper is doing nothing useful, as it only
ever returns NULL. Let's drop the const, which will let us use it in
both types of function.

ci: skip CVS and P4 tests in leaks job, too
Looking at the CI logs, the p4 and cvs tests account for another 24
minutes of test time and they offer minimal value for quite a
similar reason as the previous step.
Let's introduce and use a mechanism to skip these tests to save
some resources.

I noticed recently that the leak-checking jobs still take a lot of time,
and upon analysis, the git-svn tests contribute significantly to this.
Analyzing a recent CI run, I saw that the Git test suite contains
1,017 tests, running for approximately 5¼ hours total. Of these, 65
git-svn-related tests (~6% of test count) took 42.24 minutes combined,
accounting for ~13.% of the total runtime. This implies that the git-svn
tests are roughly twice as expernsive compared to the other tests.
However, testing git-svn in the leak-checking jobs provides minimal
value: git-svn is implemented as a Perl script, and leak checking only
handles C code. While git-svn does call into Git's built-in commands
that are implemented in C, these are standard Git operations that are
already thoroughly exercised elsewhere in the test suite. Therefore,
running the git-svn tests in the leak-checking jobs only adds to the
overall run time with little value in return.
Given that the leak-checking jobs are particularly time-intensive and
these 42+ minutes of SVN tests per job provide no additional leak
detection value, skip them in the *-leaks jobs to reduce CI runtime.
