The `test-tool genrandom` test helper can be used to generate random
data, either as an infinite stream or with a specified number of bytes.
The way we handle parsing the number of bytes is lacking though:
- We don't have good error handling, so if the caller for example uses
`test-tool genrandom 200xyz` then we'll end up generating 200 bytes
of random data successfully.
- Many callers want to generate e.g. 1 kilobyte or megabyte of data,
but they have to either use unwieldy numbers like 1048576, or they
have to precompute them.
Fix both of these issues by using `git_parse_ulong()` to parse the
argument. This function has better error handling, and it knows to
handle unit suffixes.
Adapt a couple of our tests to use suffixes instead of manual
computations.

The "ci/run-test-slice.sh" script can be used to slice up all of our
tests into N pieces and then run each of them on a separate CI job.
This is used by both GitLab and GitHub CI to speed up Windows tests,
which would otherwise be painfully slow.
The infra itself is fueled by `test-tool path-utils slice-tests`. This
tool receives as input an "offset" and a "stride" that can be combined
to slice up tests. This framing can be misleading though: you are
expected to pass a zero-based index as "offset", and the complete number
of slices to the "stride". The latter makes sense, but it is somewhat
surprising that the offset needs to be zero-based. And this is in fact
biting us: while GitHub passes zero-based indices, GitLab passes
`$CI_NODE_INDEX`, which is a one-based indice.
Ideally, we should have verification that the parameters make sense.
And naturally, one would for example expect that it's an error to call
the binary with an offset larger than the stride. But with the current
framing as "offset" it's not even wrong to do so, as it is of course
well-defined to start at a larger offset than the stride.
This means that we get this wrong on GitLab's CI, as we pass a one based
index there, and this causes us to skip one of the tests. Interestingly,
it's not the lexicographically first test that we skip. Instead, as we
sort tests by size before slicing them, we skip the _smallest_ test.
Reframe the problem to instead talk about "slice number" and "total
number of slices". For all of our use cases this is semantically
equivalent, but it allows us to perform some verifications:
- The total number of slices must be greater than 1.
- The selected slice must be between 1 <= nr <= slices_total.
As the indices are now one-based it means that GitLab's CI is fixed.
The GitHub workflow is updated accordingly.

Add a new test helper "400ancestry" to the trace2 test-tool that
spawns a child process with a controlled trace2 environment, capturing
only the child's trace2 output (including cmd_ancestry events) in
isolation.
The helper clears all inherited GIT_TRACE2* variables in the child
and enables only the requested target (normal, perf, or event),
directing output to a specified file. This gives the test suite a
reliable way to capture cmd_ancestry events: the child always sees
"test-tool" as its immediate parent in the process ancestry, providing
a predictable value to verify in tests.

If a user of the run_processes_parallel() API wants to pipe a large
amount of information to the stdin of each parallel command, that
data could exceed the pipe buffer of the process's stdin and can be
too big to store in-memory via strbuf & friends or to slurp to a file.
Generally this is solved by repeatedly writing to child_process.in
between calls to start_command() and finish_command(). For a specific
pre-existing example of this, see transport.c:run_pre_push_hook().
This adds a generic callback API to run_processes_parallel() to do
exactly that in a unified manner, similar to the existing callback APIs,
which can then be used by hooks.h to convert the remaining hooks to the
new, simpler parallel interface.

This reverts commit f406b8955295d01089ba2baf35eceadff2d11cae,
reversing changes made to 1627809eeff75e6ec936fc609e7be46d5eb2fa9e.
It seems to have caused a few regressions, two of the three known
ones we have proposed solutions for. Let's give ourselves a bit
more room to maneuver during the pre-release freeze period and
restart once the 2.53 ships.

Our coding guidelines say that:
Functions that operate on `struct S` are named `S_<verb>()` and should
generally receive a pointer to `struct S` as first parameter.
While most of the functions related to `struct commit_list` already
follow that naming schema, `free_commit_list()` doesn't.
Rename the function to address this and adjust all of its callers. Add a
compatibility wrapper for the old function name to ease the transition
and avoid any semantic conflicts with in-flight patch series. This
wrapper will be removed once Git 2.53 has been released.

Some callers, for example server-side hooks which wish to relay hook
output to clients across a transport, want to capture what would
normally print to stderr and do something else with it. Allow that via a
callback.
By calling the callback regardless of whether there's output available,
we allow clients to send e.g. a keepalive if necessary.
Because we expose a strbuf, not a fd or FILE*, there's no need to create
a temporary pipe or similar - we can just skip the print to stderr and
instead hand it to the caller.

In a subsequent commit, byte size values displayed in table output for
the git-repo(1) "structure" subcommand will be shown in a more
human-readable format with the appropriate unit prefixes. For this
usecase, the downscaled values and unit strings must be handled
separately to ensure proper column alignment.
Split out logic from strbuf_humanise() to downscale byte values and
determine the corresponding unit prefix into a separate humanise_bytes()
function that provides seperate value and unit strings.
Note that the "byte" string in "t/helper/test-simple-ipc.c" is unmarked
for translation here so that it doesn't conflict with the newly defined
plural "byte/bytes" translation and instead uses it.

The "repository" test helper sets up `the_repository` twice. In fact

where setting up the repository repeatedly will lead to a `BUG()`.

We test xmkstemp() in our helper by just calling:
xmkstemp(xstrdup(argv[1]));
This leaks both the copied string as well as the descriptor returned by
the function. In practice this isn't a big deal, since we immediately
exit the program, but:
1. LSan will complain about the memory leak. The only reason we did
not notice this in our leak-checking builds is that both of the
callers in the test suite (both in t0070) pass a broken template
(and expect failure). So the function calls die() before we can
actually leak.
But it's an accident waiting to happen if anybody adds a call which
succeeds.
2. Coverity complains about the descriptor leak. There's a long list
of uninteresting or false positives in Coverity's results, but
since we're here we might as well fix it, too.
I didn't bother adding a new test that triggers the leak. It's not even
in real production code, but just in the test-helper itself.

Leakfix.
* jk/test-delete-gpgsig-leakfix:
test-tool: fix leak in delete-gpgsig command
|

When peeling a tag to a non-tag object we repeatedly call
`parse_object()` on the tagged object until we find the first object
that isn't a tag. While this feels sensible at first, there is a big
catch here: `parse_object()` doesn't actually verify the type of the
tagged object.
The relevant code path here eventually ends up in `parse_tag_buffer()`.
Here, we parse the various fields of the tag, including the "type". Once
we've figured out the type and the tagged object ID, we call one of the
`lookup_${type}()` functions for whatever type we have found. There is
two possible outcomes in the successful case:
1. The object is already part of our cached objects. In that case we
double-check whether the type we're trying to look up matches the
type that was cached.
2. The object is _not_ part of our cached objects. In that case, we
simply create a new object with the expected type, but we don't
parse that object.
In the first case we might notice type mismatches, but only in the case
where our cache has the object with the correct type. In the second
case, we'll blindly assume that the type is correct and then go with it.
We'll only notice that the type might be wrong when we try to parse the
object at a later point.
Now arguably, we could change `parse_tag_buffer()` to verify the tagged
object's type for us. But that would have the effect that such a tag
cannot be parsed at all anymore, and we have a small bunch of tests for
exactly this case that assert we still can open such tags. So this
change does not feel like something we can retroactively tighten, even
though one shouldn't ever hit such corrupted tags.
Instead, add a new `flags` field to `peel_object()` that allows the
caller to opt in to strict object verification. This will be wired up at
a subset of callsites over the next few commits.
Note that this change also inlines `deref_tag_noverify()`. There's only
been two callsites of that function, the one we're changing and one in
our test helpers. The latter callsite can trivially use `deref_tag()`
instead, so by inlining the function we avoid having to pass down the
flag.

The `each_ref_fn` callback function type is used across our code base
for several different functions that iterate through reference. There's
a bunch of callbacks implementing this type, which makes any changes to
the callback signature extremely noisy. An example of the required churn
is e8207717f1 (refs: add referent to each_ref_fn, 2024-08-09): adding a
single argument required us to change 48 files.
It was already proposed back then [1] that we might want to introduce a
wrapper structure to alleviate the pain going forward. While this of
course requires the same kind of global refactoring as just introducing
a new parameter, it at least allows us to more change the callback type
afterwards by just extending the wrapper structure.
One counterargument to this refactoring is that it makes the structure
more opaque. While it is obvious which callsites need to be fixed up
when we change the function type, it's not obvious anymore once we use
a structure. That being said, we only have a handful of sites that
actually need to populate this wrapper structure: our ref backends,
"refs/iterator.c" as well as very few sites that invoke the iterator
callback functions directly.
Introduce this wrapper structure so that we can adapt the iterator
interfaces more readily.

Many of the commit-graph related functions take in both a repository and
the object database source (directly or via `struct commit_graph`) for
which we are supposed to load such a commit-graph. In the best case this
information is simply redundant as the source already contains a
reference to its owning object database, which in turn has a reference
to its repository. In the worst case this information could even
mismatch when passing in a source that doesn't belong to the same
repository.
Refactor the code so that we only pass in the object database source in
those cases.
There is one exception though, namely `load_commit_graph_chain_fd_st()`,
which is responsible for loading a commit-graph chain. It is expected
that parts of the commit-graph chain aren't located in the same object
source as the chain file itself, but in a different one. Consequently,
this function doesn't work on the source level but on the database level
instead.

Multi-pack indices store some information that is redundant with their
owning source:
- The locality bit that tracks whether the source is the primary
object source or an alternate.
- The object directory path the multi-pack index is located in.
- The pointer to the owning parent directory.
All of this information is already contained in `struct odb_source`. So
now that we always have that struct available when loading a multi-pack
index we have it readily accessible.
Drop the redundant information and instead store a pointer to the object
source.

To load a multi-pack index the caller is expected to pass both the
repository and the object directory where the multi-pack index is
located. While this works, this layout has a couple of downsides:
- We need to pass in information reduntant with the owning source,
namely its object directory and whether the source is local or not.
- We don't have access to the source when loading the multi-pack
index. If we had that access, we could store a pointer to the owning
source in the MIDX and thus deduplicate some information.
- Multi-pack indices are inherently specific to the object source and
its format. With the goal of pluggable object backends in mind we
will eventually want the backends to own the logic of reading and
writing multi-pack indices. Making the logic work on top of object
sources is a step into that direction.
Refactor loading of multi-pack indices accordingly.
This surfaces one small problem though: git-multi-pack-index(1) and our
MIDX test helper both know to read and write multi-pack-indices located
in a different object directory. This issue is addressed by adding the
user-provided object directory as an in-memory alternate.

There are a couple of functions that take both a `struct repository` and
a `struct multi_pack_index`. This provides redundant information though
without much benefit given that the multi-pack index already has a
pointer to its owning repository.
Drop the `struct repository` parameter from such functions. While at it,
reorder the list of parameters of `fill_midx_entry()` so that the MIDX
comes first to better align with our coding guidelines.

With `refs_for_each_reflog_ent()` callers can iterate through all the
reflog entries for a given reference. The callback that is being invoked
for each such entry does not receive the name of the reference that we
are currently iterating through. This isn't really a limiting factor, as
callers can simply pass the name via the callback data.
But this layout sometimes does make for a bit of an awkward calling
pattern. One example: when iterating through all reflogs, and for each
reflog we iterate through all refnames, we have to do some extra book
keeping to track which reference name we are currently yielding reflog
entries for.
Change the signature of the callback function so that the reference name
of the reflog gets passed through to it. Adapt callers accordingly and
start using the new parameter in trivial cases. The next commit will
refactor the reference migration logic to make use of this parameter so
that we can simplify its logic a bit.

The config API had a set of convenience wrapper functions that
implicitly use the_repository instance; they have been removed and
inlined at the calling sites.

Thanks to the new STRING_LIST_SPLIT_NONEMPTY flag, a common pattern
to split a string into a string list and then remove empty items in
the resulting list is no longer needed. Instead, just tell the
string_list_split*() to omit empty ones while splitting.

The string_list_split_in_place() function was updated by 52acddf3
(string-list: multi-delimiter `string_list_split_in_place()`,
2023-04-24) to take more than one delimiter characters, hoping that
we can later use it to replace our uses of strtok(). We however did
not make a matching change to the string_list_split() function,
which is very similar.
Before giving both functions more features in future commits, allow
string_list_split() to also take more than one delimiter characters
to make them closer to each other.
