The code's evolution left in some bits surrounding enum rebase_type that
don't really make sense any more. In particular, it makes no sense to
invoke imply_merge() if the type is already known not to be
REBASE_APPLY, and it makes no sense to assign the type after calling
imply_merge().
enum rebase_type had more values until commit a74b35081c ("rebase: drop
support for `--preserve-merges`") and commit 10cdb9f38a ("rebase: rename
the two primary rebase backends"). The latter commit also renamed

daemon: free listen_addr before returning
We build up a string list of listen addresses from the command-line
arguments, but never free it. This causes t5811 to complain of a leak
(though curiously it seems to do so only when compiled with gcc, not
with clang).
To handle this correctly, we have to do a little refactoring:
- there are two exit points from the main function, depending on
whether we are entering the main loop or serving a single client
(since rather than a traditional fork model, we re-exec ourselves
with the extra "--serve" argument to accommodate Windows).
We don't need --listen at all in the --serve case, of course, but it
is passed along by the parent daemon, which simply copies all of the
command-line options it got.
- we just "return serve()" to run the main loop, giving us no chance
to do any cleanup
So let's use a "ret" variable to store the return code, and give
ourselves a single exit point at the end. That gives us one place to do
cleanup.
Note that this code also uses the "use a no-dup string-list, but
allocate strings we add to it" trick, meaning string_list_clear() will
not realize it should free them. We can fix this by switching to a "dup"
string-list, but using the "append_nodup" function to add to it (this is
preferable to tweaking the strdup_strings flag before clearing, as it

revision: clear decoration structs during release_revisions()
The point of release_revisions() is to free memory associated with the
rev_info struct, but we have several "struct decoration" members that
are left untouched. Since the previous commit introduced a function to

We do have to provide some specialized callbacks to map the void
pointers onto real ones (the alternative would be casting the existing
function pointers; this generally works because "void *" is usually
interchangeable with a struct pointer, but it is technically forbidden
by the standard).
Since the line-log code does not expose the type it stores in the
decoration (nor of course the function to free it), I put this behind a
generic line_log_free() entry point. It's possible we may need to add
more line-log specific bits anyway (running t4211 shows a number of
other leaks in the line-log code).
While this doubtless cleans up many leaks triggered by the test suite,

builtin/repack.c: avoid making cruft packs preferred
When doing a `--geometric` repack, we make sure that the preferred pack
(if writing a MIDX) is the largest pack that we *didn't* repack. That
has the effect of keeping the preferred pack in sync with the pack
containing a majority of the repository's reachable objects.
But if the repository happens to double in size, we'll repack
everything. Here we don't specify any `--preferred-pack`, and instead
let the MIDX code choose.
In the past, that worked fine, since there would only be one pack to
choose from: the one we just wrote. But it's no longer necessarily the
case that there is one pack to choose from. It's possible that the
repository also has a cruft pack, too.
If the cruft pack happens to come earlier in lexical order (and has an
earlier mtime than any non-cruft pack), we'll pick that pack as
preferred. This makes it impossible to reuse chunks of the reachable
pack verbatim from pack-objects, so is sub-optimal.
Luckily, this is a somewhat rare circumstance to be in, since we would
have to repack the entire repository during a `--geometric` repack, and
the cruft pack would have to sort ahead of the pack we just created.

builtin/repack.c: implement support for `--max-cruft-size`
Cruft packs are an alternative mechanism for storing a collection of
unreachable objects whose mtimes are recent enough to avoid being
pruned out of the repository.
When cruft packs were first introduced back in b757353676
(builtin/pack-objects.c: --cruft without expiration, 2022-05-20) and a7d493833f (builtin/pack-objects.c: --cruft with expiration,
2022-05-20), the recommended workflow consisted of:
- Repacking periodically, either by packing anything loose in the
repository (via `git repack -d`) or producing a geometric sequence
of packs (via `git repack --geometric=<d> -d`).
- Every so often, splitting the repository into two packs, one cruft
to store the unreachable objects, and another non-cruft pack to
store the reachable objects.
Repositories may (out of band with the above) choose periodically to
prune out some unreachable objects which have aged out of the grace
period by generating a pack with `--cruft-expiration=<approxidate>`.
This allowed repositories to maintain relatively few packs on average,
and quarantine unreachable objects together in a cruft pack, avoiding
the pitfalls of holding unreachable objects as loose while they age out
(for more, see some of the details in 3d89a8c118
(Documentation/technical: add cruft-packs.txt, 2022-05-20)).
This all works, but can be costly from an I/O-perspective when
frequently repacking a repository that has many unreachable objects.
This problem is exacerbated when those unreachable objects are rarely
(if every) pruned.
Since there is at most one cruft pack in the above scheme, each time we
update the cruft pack it must be rewritten from scratch. Because much of
the pack is reused, this is a relatively inexpensive operation from a
CPU-perspective, but is very costly in terms of I/O since we end up
rewriting basically the same pack (plus any new unreachable objects that
have entered the repository since the last time a cruft pack was
generated).
At the time, we decided against implementing more robust support for
multiple cruft packs. This patch implements that support which we were
lacking.
Introduce a new option `--max-cruft-size` which allows repositories to
accumulate cruft packs up to a given size, after which point a new
generation of cruft packs can accumulate until it reaches the maximum
size, and so on. To generate a new cruft pack, the process works like
so:
- Sort a list of any existing cruft packs in ascending order of pack
size.
- Starting from the beginning of the list, group cruft packs together
while the accumulated size is smaller than the maximum specified
pack size.
- Combine the objects in these cruft packs together into a new cruft
pack, along with any other unreachable objects which have since
entered the repository.
Once a cruft pack grows beyond the size specified via `--max-cruft-size`
the pack is effectively frozen. This limits the I/O churn up to a
quadratic function of the value specified by the `--max-cruft-size`
option, instead of behaving quadratically in the number of total
unreachable objects.
When pruning unreachable objects, we bypass the new code paths which
combine small cruft packs together, and instead start from scratch,
passing in the appropriate `--max-pack-size` down to `pack-objects`,
putting it in charge of keeping the resulting set of cruft packs sized
correctly.
This may seem like further I/O churn, but in practice it isn't so bad.
We could prune old cruft packs for whom all or most objects are removed,
and then generate a new cruft pack with just the remaining set of
objects. But this additional complexity buys us relatively little,
because most objects end up being pruned anyway, so the I/O churn is
well contained.

This option is parsed with OPT_STRING, meaning that we'll accept
anything as input, punting on more fine-grained validation until we get
down into pack-objects.
This is fine, but it's wasteful to spend an entire sub-process just to
figure out that one of its option is bogus. Instead, parse the value of
`--max-pack-size` with OPT_MAGNITUDE in 'git repack', and then pass the

commit-graph: move slab-clearing to close_commit_graph()
When closing and freeing a commit-graph, the main entry point is
close_commit_graph(), which then uses close_commit_graph_one() to
recurse through the base_graph links and free each one.
Commit 957ba814bf (commit-graph: when closing the graph, also release
the slab, 2021-09-08) put the call to clear the slab into the recursive
function, but this is pointless: there's only a single global slab
variable. It works OK in practice because clearing the slab is
idempotent, but it makes the code harder to reason about and refactor.
Move it into the parent function so it's only called once (and there are
no other direct callers of the recursive close_commit_graph_one(), so we
are not hurting them).

merge: free result of repo_get_merge_bases()

repack: implement `--filter-to` for storing filtered out objects
A previous commit has implemented `git repack --filter=<filter-spec>` to
allow users to filter out some objects from the main pack and move them
into a new different pack.
It would be nice if this new different pack could be created in a
different directory than the regular pack. This would make it possible
to move large blobs into a pack on a different kind of storage, for
example cheaper storage.
Even in a different directory, this pack can be accessible if, for
example, the Git alternates mechanism is used to point to it. In fact
not using the Git alternates mechanism can corrupt a repo as the
generated pack containing the filtered objects might not be accessible
from the repo any more. So setting up the Git alternates mechanism
should be done before using this feature if the user wants the repo to
be fully usable while this feature is used.
In some cases, like when a repo has just been cloned or when there is no
other activity in the repo, it's Ok to setup the Git alternates
mechanism afterwards though. It's also Ok to just inspect the generated
packfile containing the filtered objects and then just move it into the
'.git/objects/pack/' directory manually. That's why it's not necessary
for this command to check that the Git alternates mechanism has been
already setup.
While at it, as an example to show that `--filter` and `--filter-to`
work well with other options, let's also add a test to check that these

This new option puts the objects specified by `<filter-spec>` into a
separate packfile.
This could be useful if, for example, some blobs take up a lot of
precious space on fast storage while they are rarely accessed. It could
make sense to move them into a separate cheaper, though slower, storage.
It's possible to find which new packfile contains the filtered out
objects using one of the following:
- `git verify-pack -v ...`,
- `test-tool find-pack ...`, which a previous commit added,
- `--filter-to=<dir>`, which a following commit will add to specify
where the pack containing the filtered out objects will be.
This feature is implemented by running `git pack-objects` twice in a
row. The first command is run with `--filter=<filter-spec>`, using the
specified filter. It packs objects while omitting the objects specified
by the filter. Then another `git pack-objects` command is launched using
`--stdin-packs`. We pass it all the previously existing packs into its
stdin, so that it will pack all the objects in the previously existing
packs. But we also pass into its stdin, the pack created by the previous
`git pack-objects --filter=<filter-spec>` command as well as the kept
packs, all prefixed with '^', so that the objects in these packs will be
omitted from the resulting pack. The result is that only the objects
filtered out by the first `git pack-objects` command are in the pack
resulting from the second `git pack-objects` command.
As the interactions with kept packs are a bit tricky, a few related
tests are added.

can, and this is just an optimization). But it's a bad thing for
"commit-graph verify", which should be careful about finding any

"tip" case is what is fixed by this patch (it complains to stderr but

Likewise the existing tests for corruption of the commit-graph-chain

the "base" case, but the "tip" case can now do so, too.

commit-graph: detect read errors when verifying graph chain
Because it's OK to not have a graph file at all, the graph_verify()
function needs to tell the difference between a missing file and a real
error. So when loading a traditional graph file, we call
open_commit_graph() separately from load_commit_graph_chain_fd_st(), and
don't complain if the first one fails with ENOENT.
When the function learned about chain files in 3da4b609bb (commit-graph:
verify chains with --shallow mode, 2019-06-18), we couldn't be as
careful, since the only way to load a chain was with
read_commit_graph_one(), which did both the open/load as a single unit.
So we'll miss errors in chain files we load, thinking instead that there
was just no chain file at all.
Note that we do still report some of these problems to stderr, as the
loading function calls error() and warning(). But we'd exit with a
successful exit code, which is wrong.
We can fix that by using the recently split open/load functions for
chains. That lets us treat the chain file just like a single file with
respect to error handling here.
An existing test (from 3da4b609bb) shows off the problem; we were
expecting "commit-graph verify" to report success, but that makes no
sense. We did not even verify the contents of the graph data, because we
couldn't load it! I don't think this was an intentional exception, but

commit-graph: factor out chain opening function
The load_commit_graph_chain() function opens the chain file and all of
the slices of graph that it points to. If there is no chain file (which
is a totally normal condition), we return NULL. But if we run into
errors with the chain file or loading the actual graph data, we also
return NULL, and the caller cannot tell the difference.
The caller can check for ENOENT for the unremarkable "no such file"
case. But I'm hesitant to assume that the rest of the function would
never accidentally set errno to ENOENT itself, since it is opening the
slice files (and that would mean the caller fails to notice a real
error).
So let's break this into two functions: one to open the file, and one to
actually load it. This matches the interface we provide for the
non-chain graph file, which will also come in handy in a moment when we
fix some bugs in the "git commit-graph verify" code.
Some notes:
- I've kept the "1 is good, 0 is bad" return convention (and the weird
"fd" out-parameter) used by the matching open_commit_graph()
function and other parts of the commit-graph code. This is unlike
most of the rest of Git (which would just return the fd, with -1 for
error), but it makes sense to stay consistent with the adjacent bits
of the API here.
- The existing chain loading function will quietly return if the file
is too small to hold a single entry. I've retained that behavior
(and explicitly set ENOENT in the opener function) for now, under
the notion that it's probably valid (though I'd imagine unusual) to
have an empty chain file.
There are two small behavior changes here, but I think both are strictly
positive:
1. The original blindly did a stat() before checking if fopen()
succeeded, meaning we were making a pointless extra stat call.
2. We now use fstat() to check the file size. The previous code using
a regular stat() on the pathname meant we could technically race
with somebody updating the chain file, and end up with a size that
does not match what we just opened with fopen(). I doubt anybody
ever hit this in practice, but it may have caused an out-of-bounds
read.
We'll retain the load_commit_graph_chain() function which does both the
open and reading steps (most existing callers do not care about seeing
errors anyway, since loading commit-graphs is optimistic).

bulk-checkin: only support blobs in index_bulk_checkin
As the code is written today index_bulk_checkin only accepts blobs.
Remove the enum object_type parameter and rename index_bulk_checkin to
index_blob_bulk_checkin, index_stream to index_blob_stream,
deflate_to_pack to deflate_blob_to_pack, stream_to_pack to
stream_blob_to_pack, to make this explicit.
Not supporting commits, tags, or trees has no downside as it is not
currently supported now, and commits, tags, and trees being smaller by
design do not have the problem that the problem that index_bulk_checkin
was built to solve.
Before we start adding code to support the hash function transition
supporting additional objects types in index_bulk_checkin has no real
additional cost, just an extra function parameter to know what the
object type is. Once we begin the hash function transition this is not
the case.
The hash function transition document specifies that a repository with
compatObjectFormat enabled will compute and store both the SHA-1 and
SHA-256 hash of every object in the repository.
What makes this a challenge is that it is not just an additional hash
over the same object. Instead the hash function transition document
specifies that the compatibility hash (specified with
compatObjectFormat) be computed over the equivalent object that another
git repository whose storage hash (specified with objectFormat) would
store. When comparing equivalent repositories built with different
storage hash functions, the oids embedded in objects used to refer to
other objects differ and the location of signatures within objects
differ.
As blob objects have neither oids referring to other objects nor stored
signatures their storage hash and their compatibility hash are computed
over the same object.
The other kinds of objects: trees, commits, and tags, all store oids
referring to other objects. Signatures are stored in commit and tag
objects. As oids and the tags to store signatures are not the same size
in repositories built with different storage hashes the size of the
equivalent objects are also different.
A version of index_bulk_checkin that supports more than just blobs when
computing both the SHA-1 and the SHA-256 of every object added would
need a different, and more expensive structure. The structure is more
expensive because it would be required to temporarily buffering the
equivalent object the compatibility hash needs to be computed over.
A temporary object is needed, because before a hash over an object can
computed it's object header needs to be computed. One of the members of
the object header is the entire size of the object. To know the size of
an equivalent object an entire pass over the original object needs to be
made, as trees, commits, and tags are composed of a variable number of
variable sized pieces. Unfortunately there is no formula to compute the
size of an equivalent object from just the size of the original object.
Avoid all of those future complications by limiting index_bulk_checkin

Add mailmap support to ref-filter formats which are similar in
pretty. This support is such that the following pretty placeholders are
equivalent to the new ref-filter atoms:
Additionally, mailmap can also be used with ":trim" option for email by
doing something like "authoremail:mailmap,trim".
The above also applies for the "tagger" atom, that is,
"taggername:mailmap", "taggeremail:mailmap", "taggeremail:mailmap,trim"
and "taggername:mailmap,localpart".
The functionality of ":trim" and ":localpart" remains the same. That is,
":trim" gives the email, but without the angle brackets and ":localpart"
gives the part of the email before the '@' character (if such a
character is not found then we directly grab everything between the
angle brackets).

Introduce a new function "test_bad_atom", which is similar to
"test_atom()" but should be used to check whether the correct error
message is shown on stderr.
Like "test_atom", the new function takes three arguments. The three
arguments specify the ref, the format and the expected error message
respectively, with an optional fourth argument for tweaking
"test_expect_*" (which is by default "success").

Previously, when the executable part of "test_expect_{success,failure}"
(inside "test_atom") got "eval"ed, it would have been syntactically
incorrect if the second argument ($2, which is the format) to "test_atom"
were enclosed in single quotes because the $variables would get
interpolated even before the arguments to "test_expect_{success,failure}"
are formed.
So fix this and also some style issues along the way.
