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.

If neither HAVE_DEV_TTY nor GIT_WINDOWS_NATIVE is set, the fallback
code calls the system getpass(). This unfortunately ignores the "echo"
boolean parameter, as we have no way to implement that functionality.
But we still have to keep the unused parameter, since our interface
has to match the other implementations.

In git-log we leave the save_commit_buffer flag set to "1", which tells
the commit parsing code to store the object content after it has parsed
it to find parents, tree, etc. That lets us reuse the contents for
pretty-printing the commit in the output. And then after printing each
commit, we call free_commit_buffer(), since we don't need it anymore.
But some options may cause us to traverse commits which are not part of
the output. And so git-log does not see them at all, and doesn't free
them. One such case is something like:
git log -n 1000 --skip=1000000
which will churn through a million commits, before showing only a
thousand. We loop through these inside get_revision(), without freeing
the contents. As a result, we end up storing the object data for those
million commits simultaneously.
We should free the stored buffers (if any) for those commits as we skip
over them, which is what this patch does. Running the above command in
linux.git drops the peak heap usage from ~1.1GB to ~200MB, according to
valgrind/massif. (I thought we might get an even bigger improvement, but
the remaining memory is going to commit/tree structs, which we do hold
on to forever).
Note that this problem doesn't occur if:
- you're running a git-rev-list without a --format parameter; it turns
off save_commit_buffer by default, since it only output the object
id
- you've built a commit-graph file, since in that case we'd use the
optimized graph data instead of the initial parse, and then do a
lazy parse for commits we're actually going to output
There are probably some other option combinations that can likewise
end up with useless stored commit buffers. For example, if you ask for
"foo..bar", then we'll have to walk down to the merge base, and
everything on the "foo" side won't be shown. Tuning the "save" behavior
to handle that might be tricky (I guess maybe drop buffers for anything
we mark as UNINTERESTING?). And in the long run, the right solution here
is probably to make sure the commit-graph is built (since it fixes the
memory problem _and_ drastically reduces CPU usage).
But since this "--skip" case is an easy one-liner, it's worth fixing in
the meantime. It should be OK to make this call even if there is no
saved buffer (e.g., because save_commit_buffer=0, or because a
commit-graph was used), since it's O(1) to look up the buffer and is a
noop if it isn't present. I verified by running the above command after
"git commit-graph write --reachable", and it takes the same time with
and without this patch.

Boolean that says "the name given is not literal, but a pattern to
match the name".

"git config --get-all foo.bar" shows all values for the foo.bar
variable, but does not give the variable name in each output entry.
Hence it is equivalent to "git config get --all foo.bar", without
"--show-names", in the more modern syntax.

The batched mode of git-cat-file(1) reads multiple objects from stdin
and prints their respective contents to stdout.
The order in which those objects are printed is not documented

As we have operated with "write like how your surrounding code is
written" for too long, after a huge code drop from another project,
we'll end up being inconsistent before such an imported code is
cleaned up. We have many uses of cast operator with a space before
its operand, mostly in the reftable code.
Spell the convention out before it spreads to other places.
