When cloning an empty repository, protocol versions 0 and 1 currently
offer nothing but the header and flush packets for the /info/refs
endpoint. This means that no capabilities are provided, so the client
side doesn't know what capabilities are present.
However, this does pose a problem when working with SHA-256
repositories, since we use the capabilities to know the remote side's
object format (hash algorithm). As of 8b214c2e9d ("clone: propagate
object-format when cloning from void", 2023-04-05), this has been fixed
for protocol v2, since there we always read the hash algorithm from the
remote.
Fortunately, the push version of the protocol already indicates a clue
for how to solve this. When the /info/refs endpoint is accessed for a
push and the remote is empty, we include a dummy "capabilities^{}" ref
pointing to the all-zeros object ID. The protocol documentation already
indicates this should _always_ be sent, even for fetches and clones, so
let's just do that, which means we'll properly announce the hash
algorithm as part of the capabilities. This just works with the
existing code because we share the same ref code for fetches and clones,
and libgit2, JGit, and dulwich do as well.
There is one minor issue to fix, though. If we called send_ref with
namespaces, we would return NULL with the capabilities entry, which
would cause a crash. Instead, let's refactor out a function to print
just the ref itself without stripping the namespace and use it for our
special capabilities entry.
Add several sets of tests for HTTP as well as for local clones. The
behavior can be slightly different for HTTP versus a local or SSH clone
because of the stateless-rpc functionality, so it's worth testing both.

Git 2.41-rc0 fails to compile run-command.c with `NO_PTHREADS` defined,
i.e.
$ make NO_PTHREADS=1 run-command.o
as `ALLOC_GROW()` macro is used in the `atexit()` emulation but the
macro definition is not available.
This bisects to 36bf195890 (alloc.h: move ALLOC_GROW() functions from
cache.h, 2023-02-24), which replaced includes of <cache.h> with
<alloc.h>, which is the new home of `ALLOC_GROW()` (and
`ALLOC_GROW_BY()`).
We can see that run-command.c is the only one that try to use these
macros without including <alloc.h>.
$ git grep -l -e '[^_]ALLOC_GROW(' -e 'ALLOC_GROW_BY(' \*.c | sort >/tmp/1
$ git grep -l 'alloc\.h' \*.c | sort >/tmp/2
$ comm -23 /tmp/[12]
compat/simple-ipc/ipc-unix-socket.c
run-command.c
The "compat/" file only talks about the macro in the comment,
and is not broken.
We could fix this by conditionally including "alloc.h" when
`NO_PTHREADS` is defined. But we have relatively few examples of
conditional includes throughout the tree[^1].
Instead, include "alloc.h" unconditionally in run-command.c to allow it
to successfully compile even when NO_PTHREADS is defined.

These tests use "! test_path_is_dir" or "! test_path_is_file" to
ensure that the path is not recursively checked out or "submodule
update" did not touch the working tree.
Use "test_path_is_missing" to assert that the path does not exist,
instead of negating test_path_is_* helpers; they are designed to be
loud in wrong occasions. Besides, negating "test_path_is_dir" would
mean we would be happy if a file exists there, which is not the case
for these tests.

In this test, a path (some_dir) that is originally a directory is to
be removed and then to be replaced with a file of the same name.
The expectation is that the path becomes a file at the end.
However, "! test_path_is_dir some_dir" is used to catch a breakage
that leaves the path as a directory.
But as with all the "test_path_is..." helpers, this use of the
helper makes it loud when the expectation (i.e. it is a directory)
is met, and otherwise is silent when it is not---this does not help
debugging.
Be more explicit and state that we expect the path to become a file.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
As a way to assert the path 'foo' is missing, "! test_path_exists
foo" is a poor way to do so, as the helper is designed to complain
when 'foo' is missing, but the intention of the author who used
negated form was to make sure it does not exist. This does not
help debugging the tests.
Use test_path_is_missing instead, which is a more appropriate helper.

For regular, non-`--rebase-merges` runs, there is very little work to do
for the parser when determining the total number of commands in a rebase
script: it is simply the number of lines after stripping the commented
lines and then trimming the trailing empty line, if any.
The `--rebase-merges` mode complicates things by introducing empty lines
and comments in the middle of the script. These should _not_ be counted
as commands, and indeed, when an interactive rebase is interrupted and
subsequently resumed, the total number of commands can magically shrink,
sometimes dramatically.
The reason for this strange behavior is that empty lines _are_ counted
in `edit_todo_list()` (but not the comments, as they are stripped via
`strbuf_stripspace(..., 1)`, which is a bug.
Let's fix this so that the correct total number is shown from the
get-go, by carefully adjusting it according to what's in the rebase
script. Extra care needs to be taken in case the user edits the script:
the number of commands might be different after the user edited than
beforehand.
Note: Even though commented lines are skipped in `edit_todo_list()`, we
still need to handle `TODO_COMMENT` items by decrementing the
already-incremented `total_nr` again: empty lines are also marked as
`TODO_COMMENT`.

The `total_nr` field in the `todo_list` structure merely serves display
purposes, and should only be used when generating the progress message.
In these two instances, however, we want to loop over all of the
commands in the parsed rebase script. The loop limit therefore needs to
be `nr`, which refers to the count of commands in the current
`todo_list`.
This is important because the two numbers, `nr` and `total_nr` can
differ wildly, e.g. due to `total_nr` _not_ counting comments or empty
lines, while `nr` skips any commands that already moved from the
`git-rebase-todo` file to the `done` file.

Allow users to be more selective over which refs to pack by adding an
--include option to git-pack-refs.
The existing options allow some measure of selectivity. By default
git-pack-refs packs all tags. --all can be used to include all refs,
and the previous commit added the ability to exclude certain refs with
--exclude.
While these knobs give the user some selection over which refs to pack,
it could be useful to give more control. For instance, a repository may
have a set of branches that are rarely updated and would benefit from
being packed. --include would allow the user to easily include a set of
branches to be packed while leaving everything else unpacked.
