There are a few callback functions which are used with the fsck code,
but it's natural that not all callbacks need all parameters. For
reporting, even something as obvious as "the oid of the object which had
a problem" is not always used, as some callers are only checking a
single object in the first place. And for both reporting and walking,
things like void data pointers and the fsck_options aren't always
necessary.
But since each such parameter is used by _some_ callback, we have to
keep them in the interface. Mark the unused ones in specific callbacks
to avoid triggering -Wunused-parameter.

Geometric repacking ("git repack --geometric=<n>") in a repository
that borrows from an alternate object database had various corner
case bugs, which have been corrected.
* ps/fix-geom-repack-with-alternates:
repack: disable writing bitmaps when doing a local repack
repack: honor `-l` when calculating pack geometry
t/helper: allow chmtime to print verbosely without modifying mtime
pack-objects: extend test coverage of `--stdin-packs` with alternates
pack-objects: fix error when same packfile is included and excluded
pack-objects: fix error when packing same pack twice
pack-objects: split out `--stdin-packs` tests into separate file
repack: fix generating multi-pack-index with only non-local packs
repack: fix trying to use preferred pack in alternates
midx: fix segfault with no packs and invalid preferred pack
In order to write a bitmap, we need to have full coverage of all objects
that are about to be packed. In the traditional non-multi-pack-index
world this meant we need to do a full repack of all objects into a
single packfile. But in the new multi-pack-index world we can get away
with writing bitmaps when we have multiple packfiles as long as the
multi-pack-index covers all objects.
This is not always the case though. When asked to perform a repack of
local objects, only, then we cannot guarantee to have full coverage of
all objects regardless of whether we do a full repack or a repack with a
multi-pack-index. The end result is that writing the bitmap will fail in
both worlds:
$ git multi-pack-index write --stdin-packs --bitmap <packfiles
warning: Failed to write bitmap index. Packfile doesn't have full closure (object 1529341d78cf45377407369acb0f4ff2b5cdae42 is missing)
error: could not write multi-pack bitmap
Now there are two different ways to fix this. The first one would be to
amend git-multi-pack-index(1) to disable writing bitmaps when we notice
that we don't have full object coverage.
- We don't have enough information in git-multi-pack-index(1) in
order to tell whether the local repository _should_ have full
coverage. Because even when connected to an alternate object
directory, it may be the case that we still have all objects
around in the main object database.
- git-multi-pack-index(1) is quite a low-level tool. Automatically
disabling functionality that it was asked to provide does not feel
like the right thing to do.
We can easily fix it at a higher level in git-repack(1) though. When
asked to only include local objects via `-l` and when connected to an
alternate object directory then we will override the user's ask and
disable writing bitmaps with a warning. This is similar to what we do in
git-pack-objects(1), where we also disable writing bitmaps in case we
omit an object from the pack.

"git hash-object" now checks that the resulting object is well
formed with the same code as "git fsck".
* jk/hash-object-fsck:
fsck: do not assume NUL-termination of buffers
hash-object: use fsck for object checks
fsck: provide a function to fsck buffer without object struct
t: use hash-object --literally when created malformed objects
t7030: stop using invalid tag name
t1006: stop using 0-padded timestamps
t1007: modernize malformed object tests
Since c879daa237 (Make hash-object more robust against malformed
objects, 2011-02-05), we've done some rudimentary checks against objects
we're about to write by running them through our usual parsers for
trees, commits, and tags.
These parsers catch some problems, but they are not nearly as careful as
the fsck functions (which make sense; the parsers are designed to be
fast and forgiving, bailing only when the input is unintelligible). We
are better off doing the more thorough fsck checks when writing objects.
Doing so at write time is much better than writing garbage only to find
out later (after building more history atop it!) that fsck complains
about it, or hosts with transfer.fsckObjects reject it.
This is obviously going to be a user-visible behavior change, and the
test changes earlier in this series show the scope of the impact. But
I'd argue that this is OK:
- the documentation for hash-object is already vague about which
checks we might do, saying that --literally will allow "any
garbage[...] which might not otherwise pass standard object parsing
or git-fsck checks". So we are already covered under the documented
behavior.
- users don't generally run hash-object anyway. There are a lot of
spots in the tests that needed to be updated because creating
garbage objects is something that Git's tests disproportionately do.
- it's hard to imagine anyone thinking the new behavior is worse. Any
object we reject would be a potential problem down the road for the
user. And if they really want to create garbage, --literally is
already the escape hatch they need.
Note that the change here is actually in index_mem(), which handles the
HASH_FORMAT_CHECK flag passed by hash-object. That flag is also used by
"git-replace --edit" to sanity-check the result. Covering that with more
thorough checks likewise seems like a good thing.
Besides being more thorough, there are a few other bonuses:
- we get rid of some questionable stack allocations of object structs.
These don't seem to currently cause any problems in practice, but
they subtly violate some of the assumptions made by the rest of the
code (e.g., the "struct commit" we put on the stack and
zero-initialize will not have a proper index from
alloc_comit_index().
- likewise, those parsed object structs are the source of some small
memory leaks
- the resulting messages are much better. For example:
[before]
$ echo 'tree 123' | git hash-object -t commit --stdin
error: bogus commit object 0000000000000000000000000000000000000000
fatal: corrupt commit
[after]
$ echo 'tree 123' | git.compile hash-object -t commit --stdin
error: object fails fsck: badTreeSha1: invalid 'tree' line format - bad sha1
fatal: refusing to create malformed object

Since read_object() is these days just a thin wrapper around
oid_object_info_extended(), and since it only has two callers, let's
just inline those calls. This has a few positive outcomes:
- it's a net reduction in source code lines
- even though the callers end up with a few extra lines, they're now
more flexible and can use object_info flags directly. So no more
need to convert die_if_corrupt between parameter/flag, and we can
ask for lookup replacement with a flag rather than doing it
ourselves.
- there's one fewer function in an already crowded namespace (e.g.,
the difference between read_object() and read_object_file() was not
immediately obvious; now we only have one of them).

Even in a repository with promisor remote, it is useless to
attempt to lazily attempt fetching an object that is expected to be
commit, because no "filter" mode omits commit objects. Take
advantage of this assumption to fail fast on errors.
* jt/avoid-lazy-fetch-commits:
commit: don't lazy-fetch commits
object-file: emit corruption errors when detected
object-file: refactor map_loose_object_1()
object-file: remove OBJECT_INFO_IGNORE_LOOSE
Instead of relying on errno being preserved across function calls, teach
do_oid_object_info_extended() to itself report object corruption when
it first detects it. There are 3 types of corruption being detected:
- when a replacement object is missing
- when a loose object is corrupt
- when a packed object is corrupt and the object cannot be read
in another way
Note that in the RHS of this patch's diff, a check for ENOENT that was
introduced in 3ba7a06552 (A loose object is not corrupt if it cannot
be read due to EMFILE, 2010-10-28) is also removed. The purpose of this
check is to avoid a false report of corruption if the errno contains
something like EMFILE (or anything that is not ENOENT), in which case
a more generic report is presented. Because, as of this patch, we no
longer rely on such a heuristic to determine corruption, but surface
the error message at the point when we read something that we did not
expect, this check is no longer necessary.
Besides being more resilient, this also prepares for a future patch in
which an indirect caller of do_oid_object_info_extended() will need
such functionality.

When adding an alternate ODB, we check if the alternate has the same
path as the object dir, and if so, we do nothing. However, that
comparison does not resolve symlinks. This makes it possible to add the
object dir as an alternate, which may result in bad behavior. For
example, it can trick "git repack -a -l -d" (possibly run by "git gc")
into thinking that all packs come from an alternate and delete all
objects.
rm -rf test &&
git clone https://github.com/git/git test &&
(
cd test &&
ln -s objects .git/alt-objects &&
# -c repack.updateserverinfo=false silences a warning about not
# being able to update "info/refs", it isn't needed to show the
# bad behavior
GIT_ALTERNATE_OBJECT_DIRECTORIES=".git/alt-objects" git \
-c repack.updateserverinfo=false repack -a -l -d &&
# It's broken!
git status
# Because there are no more objects!
ls .git/objects/pack
)
Fix this by resolving symlinks and relative paths before comparing the
alternate and object dir. This lets us clean up a number of issues noted
in 37a95862c6 (alternates: re-allow relative paths from environment,
2016-11-07):
- Now that we compare the real paths, duplicate detection is no longer
foiled by relative paths.
- Using strbuf_realpath() allows us to "normalize" paths that
strbuf_normalize_path() can't, so we can stop silently ignoring errors
when "normalizing" paths from the environment.
- We now store an absolute path based on getcwd() (the "future
direction" named in 37a95862c6), so chdir()-ing in the process no
longer changes the directory pointed to by the alternate. This is a
change in behavior, but a desirable one.

Remove error detection from a function that fetches from promisor
remotes, and make it die when such a fetch fails to bring all the
requested objects, to give an early failure to various operations.
* jt/promisor-remote-fetch-tweak:
promisor-remote: die upon failing fetch
promisor-remote: remove a return value
In a partial clone, an attempt to read a missing object results in an
attempt to fetch that single object. In order to avoid multiple
sequential fetches, which would occur when multiple objects are missing
(which is the typical case), some commands have been taught to prefetch
in a batch: such a command would, in a partial clone, notice that
several objects that it will eventually need are missing, and call
promisor_remote_get_direct() with all such objects at once.
When this batch prefetch fails, these commands fall back to the
sequential fetches. But at $DAYJOB we have noticed that this results in
a bad user experience: a command would take unexpectedly long to finish
(and possibly use up a lot of bandwidth) if the batch prefetch would
fail for some intermittent reason, but all subsequent fetches would
work. It would be a better user experience for such a command would
just fail.
Therefore, make it a fatal error if the prefetch fails and at least one
object being fetched is known to be a promisor object. (The latter
criterion is to make sure that we are not misleading the user that such
an object would be present from the promisor remote. For example, a
missing object may be a result of repository corruption and not because
it is expectedly missing due to the repository being a partial clone.)

Allow large objects read from a packstream to be streamed into a

object-file.c: add "stream_loose_object()" to handle large object
object-file.c: factor out deflate part of write_loose_object()
object-file.c: refactor write_loose_object() to several steps
unpack-objects: low memory footprint for get_data() in dry_run mode
If we want unpack and write a loose object using "write_loose_object",
we have to feed it with a buffer with the same size of the object, which
will consume lots of memory and may cause OOM. This can be improved by
feeding data to "stream_loose_object()" in a stream.
Add a new function "stream_loose_object()", which is a stream version of
"write_loose_object()" but with a low memory footprint. We will use this
function to unpack large blob object in later commit.
Another difference with "write_loose_object()" is that we have no chance
to run "write_object_file_prepare()" to calculate the oid in advance.
In "write_loose_object()", we know the oid and we can write the
temporary file in the same directory as the final object, but for an
object with an undetermined oid, we don't know the exact directory for
the object.
Still, we need to save the temporary file we're preparing
somewhere. We'll do that in the top-level ".git/objects/"
directory (or whatever "GIT_OBJECT_DIRECTORY" is set to). Once we've
streamed it we'll know the OID, and will move it to its canonical
path.
"freshen_packed_object()" or "freshen_loose_object()" will be called
inside "stream_loose_object()" after obtaining the "oid". After the
temporary file is written, we wants to mark the object to recent and we
may find that where indeed is already the object. We should remove the
temporary and do not leave a new copy of the object.

2. Move common steps for starting to write loose objects into a new

Start following-up on the rename mentioned in c7c4bdeccf (run-command
API: remove "env" member, always use "env_array", 2021-11-25) of
"env_array" to "env".
The "env_array" name was picked in 19a583dc39 (run-command: add
env_array, an optional argv_array for env, 2014-10-19) because "env"
was taken. Let's not forever keep the oddity of "*_array" for this
"struct strvec", but not for its "args" sibling.
This commit is almost entirely made with a coccinelle rule[1]. The
only manual change here is in run-command.h to rename the struct
member itself and to change "env_array" to "env" in the
CHILD_PROCESS_INIT initializer.
The rest of this is all a result of applying [1]:
* make contrib/coccinelle/run_command.cocci.patch
* patch -p1 <contrib/coccinelle/run_command.cocci.patch
* git add -u
1. cat contrib/coccinelle/run_command.pending.cocci

I've avoided changing any comments and derived variable names here,
that will all be done in the next commit.
