t/unit-tests: add tests for the in-memory object source

The in-memory source stores its objects in a simple array that we grow as
needed. This has a couple of downsides:
- The object lookup is O(n). This doesn't matter in practice because
we only store a small number of objects.
- We don't have an easy way to iterate over all objects in
lexicographic order.
- We don't have an easy way to compute unique object ID prefixes.
Refactor the code to use an oidtree instead. This is the same data
structure used by our loose object source, and thus it means we get a
bunch of functionality for free.

The oidtree data structure is currently only used to store object IDs,
without any associated data. So consequently, it can only really be used
to track which object IDs exist, and we can use the tree structure to
efficiently operate on OID prefixes.
But there are valid use cases where we want to both:
- Store object IDs in a sorted order.
- Associated arbitrary data with them.
Refactor the oidtree interface so that it allows us to store arbitrary
payloads within the respective nodes. This will be used in the next
commit.

cbtree: allow using arbitrary wrapper structures for nodes
The cbtree subsystem allows the user to store arbitrary data in a
prefix-free set of strings. This is used by us to store object IDs in a
way that we can easily iterate through them in lexicograph order, and so
that we can easily perform lookups with shortened object IDs.
In its current form, it is not easily possible to store arbitrary data
with the tree nodes. There are a couple of approaches such a caller
could try to use, but none of them really work:
- One may embed the `struct cb_node` in a custom structure. This does
not work though as `struct cb_node` contains a flex array, and
embedding such a struct in another struct is forbidden.
- One may use a `union` over `struct cb_node` and ones own data type,
which _is_ allowed even if the struct contains a flex array. This
does not work though, as the compiler may align members of the
struct so that the node key would not immediately start where the
flex array starts.
- One may allocate `struct cb_node` such that it has room for both its
key and the custom data. This has the downside though that if the
custom data is itself a pointer to allocated memory, then the leak
checker will not consider the pointer to be alive anymore.
Refactor the cbtree to drop the flex array and instead take in an
explicit offset for where to find the key, which allows the caller to
embed `struct cb_node` is a wrapper struct.
Note that this change has the downside that we now have a bit of padding
in our structure, which grows the size from 60 to 64 bytes on a 64 bit
system. On the other hand though, it allows us to get rid of the memory
copies that we previously had to do to ensure proper alignment. This
seems like a reasonable tradeoff.

odb: fix unnecessary call to `find_cached_object()`
The function `odb_pretend_object()` writes an object into the in-memory
object database source. The effect of this is that the object will now
become readable, but it won't ever be persisted to disk.
Before storing the object, we first verify whether the object already
exists. This is done by calling `odb_has_object()` to check all sources,
followed by `find_cached_object()` to check whether we have already
stored the object in our in-memory source.
This is unnecessary though, as `odb_has_object()` already checks the
in-memory source transitively via:
Implement the `free()` callback function for the "in-memory" source.
Note that this requires us to define `struct cached_object_entry` in
"odb/source-inmemory.h", as it is accessed in both "odb.c" and
"odb/source-inmemory.c" now. This will be fixed in subsequent commits
though.
Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
Next to our typical object database sources, each object database also
has an implicit source of "cached" objects. These cached objects only
exist in memory and some use cases:
- They contain evergreen objects that we expect to always exist, like
for example the empty tree.
- They can be used to store temporary objects that we don't want to
persist to disk, which is used by git-blame(1) to create a fake
worktree commit.
Overall, their use is somewhat restricted though. For example, we don't
provide the ability to use it as a temporary object database source that
allows the user to write objects, but discard them after Git exists. So
while these cached objects behave almost like a source, they aren't used
as one.
This is about to change over the following commits, where we will turn
cached objects into a new "in-memory" source. This will allow us to use
it exactly the same as any other source by providing the same common
interface as the "files" source.
For now, the in-memory source only hosts the cached objects and doesn't
provide any logic yet. This will change with subsequent commits, where
we move respective functionality into the source.

object-file: avoid fd seekback by checking object size upfront
In certain scenarios, Git handles writing blobs that exceed
"core.bigFileThreshold" differently by streaming the object directly
into a packfile. When there is an active ODB transaction, these blobs
are streamed to the same packfile instead of using a separate packfile
for each. If "pack.packSizeLimit" is configured and streaming another
object causes the packfile to exceed the configured limit, the packfile
is truncated back to the previous object and the object write is
restarted in a new packfile.
This works fine, but requires the fd being read from to save a
checkpoint so it becomes possible to rewind the input source via seeking
back to a known offset at the beginning. In a subsequent commit, blob
streaming is converted to use `struct odb_write_stream` as a more
generic input source instead of an fd which doesn't provide a mechanism
for rewinding.
For this use case though, rewinding the fd is not strictly necessary
because the inflated size of the object is known and can be used to
approximate whether writing the object would cause the packfile to
exceed the configured limit prior to writing anything. These blobs
written to the packfile are never deltified thus the size difference
between what is written versus the inflated size is due to zlib
compression. While this does prevent packfiles from being filled to the
potential maximum is some cases, it should be good enough and still
prevents the packfile from exceeding any configured limit.
Use the inflated blob size to determine whether writing an object to a
packfile will exceed the configured "pack.packSizeLimit".

object-file: remove flags from transaction packfile writes

format-rev: introduce builtin for on-demand pretty formatting
Introduce a new builtin for pretty formatting one revision expression
per line or commit object names found in running text.
Sometimes you want to format commits. Most of the time you’re
walking the graph, e.g. getting a range of commits like
`master..topic`. That’s a job for git-log(1).
But there are times when you want to format commits that you encounter
on demand:
• Full hashes in running text that you might want to pretty-print
• git-last-modified(1) outputs full hashes that you can do the same
with
• git-cherry(1) has `-v` for commit subject, but maybe you want
something else?
But now you can’t use git-log(1), git-show(1), or git-rev-list(1):
• You can’t feed commits piecemeal to these commands, one input
for one output; they block until standard in is closed
• You can’t feed a list of possibly duplicate commits, like the output
of git-last-modified(1); they effectively deduplicate the output
Beyond these two points there’s also the input massage problem: you
cannot feed mixed input (revisions mixed with arbitrary text).
One might hope that git-cat-file(1) can save us. But it doesn’t
support pretty formats.
But there is one command that already both handles revisions as
arguments, revisions on standard input, and even revisions mixed in
with arbitrary text. Namely git-name-rev(1): the command for outputting
symbolic names for commits.
We made some room in `builtin/name-rev.c` two commits ago. Let’s
now add this new git-format-rev(1) command. Taking inspiration from
git-name-rev(1), there are two modes:
• revs: like git-name-rev(1) in argv mode, but one revision per line
on standard in
• text: like git-name-rev(1) with `--annotate-stdin`
***
We need to add this command to the exception list in
`t/t1517-outside-repo.sh` because it uses “EXPERIMENTAL!”
in the usage line.

build: tolerate use of _Generic from glibc 2.43 with Clang
When building with `make DEVELOPER=1` we explicitly pass "-std=gnu99" to
the compiler so that we don't start leaning on features exposed by more
recent versions of the C standard. Unfortunately though, glibc 2.43
started to use type-generic expressions. This works alright with GCC,
but when compiling with Clang this leads to errors:
$ make DEVELOPER=1 CC=clang
CC daemon.o
In file included from daemon.c:3:
./git-compat-util.h:344:11: error: '_Generic' is a C11 extension [-Werror,-Wc11-extensions]
344 | return !!strchr(path, '/');

838 | _Generic (0 ? (PTR) : (void *) 1, \
| ^
In theory, the `__glibc_const_generic` macro does have feature gating:
But this feature gating isn't effective because `_has_extension()` will
always evaluate to true as C generics _are_ available as a language
extension to GNU C99 when using Clang. This would have been different if
`_has_feature()` was used instead, in which case it would have properly
evaluated to `false`.
GCC has a workaround to squelch this warning from standard system
headers, but because clang fails due to [-Werror,-Wc11-extensions],
as it lacks the corresponding workaround.
For both meson and Makefile, pass -Wno-c11-extensions when we are
building with clang.

ci: enable EXPENSIVE for contributor builds
Earlier, we enabled EXPENSIVE tests for pushes to integration
branches. As we didn't have any CI jobs that run these tests, this
was a step in the right direction.
It however is an ineffective and inefficient use of the maintainer
time, which does not scale, to allow contributors to send changes
that are less tested at the list, only to force the maintainer
notice breakages caused by their changes but only after these
changes are mixed with changes from other contributors. The
problematic topic needs to be isolated by bisecting, and it
historically has been done by the maintainer alone.
It is far better to let the problem identified early, preferably
before the problematic code leaves the hands of the original
developer. In order for it to happen, the test coverage of the
contributor tests must be at least as wide as the coverage of the
integration tests.
Enable expensive tests for CI jobs triggered by pull requests. This
will make each contributor take care of their own, which scales much
better.
Keep the expensive tests also enabled for the pushes of integration
branches, as that is the only place we can notice problems stemming
from mismerges and inter-topic interactions, even if the topics from
the contributors in isolation all passes these tests.

rebase: ignore non-branch update-refs
The following Git configuration breaks git rebase --update-refs:
[rebase]
instructionFormat = %s%d
The '%d' format requests all available decorations for a commit,
filling the global decoration table with all of them,
which --update-refs then uses to populate 'update-ref' instructions
in the rebase todo list.
Specifically, this results in the following instruction:
update-ref HEAD
The todo parser then rejects the instruction:
error: update-ref requires a fully qualified refname e.g. refs/heads/HEAD
error: invalid line 3: update-ref HEAD
To fix, ignore decorations that are not local branches
when scanning through the table.
This matches the documented contract:
it moves branch refs under refs/heads/
and leaves display-only decorations (HEAD, tags, etc.) alone.
Verification:
A regression test that fails without this fix is included.
