In the preceding commits we have renamed the structures contained in
"object-store.h" to `struct object_database` and `struct odb_backend`.
As such, the code files "object-store.{c,h}" are confusingly named now.
Rename them to "odb.{c,h}" accordingly.

The 'git-send-pack(1)' allows users to push objects to a remote
repository and explicitly list the references to be pushed. The status
of each reference pushed is captured into a list mapped by refname.
If a reference fails to be updated, its error message is captured in the
`ref->remote_status` field. While the command allows duplicate ref
inputs, the list doesn't accommodate this behavior as a particular
refname is linked to a single `struct ref*` element. So if the user
inputs a reference twice like:
git send-pack remote.git A:foo B:foo
where the user is trying to update the same reference 'foo' twice and
the reference fails to be updated, we first fill `ref->remote_status`
with error message for the input 'A:foo' then we override the same field
with the error message for 'B:foo'. This override happens without first
free'ing the previous value. Fix this leak.
The current tests already incorporate the above example, but in the test
'A:foo' succeeds while 'B:foo' fails, meaning that the memory leak isn't
triggered. Add a new test with multiple duplicates.

As the comment of `repo_has_object_file()` and its `_with_flags()`
variant tells us, these functions are considered to be deprecated in
favor of `has_object()`. There are a couple of slight benefits in favor
of the replacement:
- The new function has a short-and-sweet name.
- More explicit defaults: `has_object()` doesn't fetch missing objects
via promisor remotes, and neither does it reload packfiles if an
object wasn't found by default. This ensures that it becomes
immediately obvious when a simple object existence check may result
in expensive actions.
Most importantly though, it is confusing that we have two sets of
functions that ultimately do the same thing, but with different
defaults.
Start sunsetting `repo_has_object_file()` and its `_with_flags()`
sibling by replacing all callsites with `has_object()`:
- `repo_has_object_file(...)` is equivalent to
`has_object(..., HAS_OBJECT_RECHECK_PACKED | HAS_OBJECT_FETCH_PROMISOR)`.
- `repo_has_object_file_with_flags(..., OBJECT_INFO_QUICK | OBJECT_INFO_SKIP_FETCH_OBJECT)`
is equivalent to `has_object(..., 0)`.
- `repo_has_object_file_with_flags(..., OBJECT_INFO_SKIP_FETCH_OBJECT)`
is equivalent to `has_object(..., HAS_OBJECT_RECHECK_PACKED)`.
- `repo_has_object_file_with_flags(..., OBJECT_INFO_QUICK)`
is equivalent to `has_object(..., HAS_OBJECT_FETCH_PROMISOR)`.
The replacements should be functionally equivalent.

The "object-store-ll.h" header has been introduced to keep transitive
header dependendcies and compile times at bay. Now that we have created
a new "object-store.c" file though we can easily move the last remaining
additional bit of "object-store.h", the `odb_path_map`, out of the
header.
Do so. As the "object-store.h" header is now equivalent to its low-level
alternative we drop the latter and inline it into the former.

Patrick reported an issue that the exit code of git-receive-pack(1) is
ignored during atomic push with "--porcelain" flag, and added new test
cases in t5543.
This issue originated from commit 7dcbeaa0df (send-pack: fix
inconsistent porcelain output, 2020-04-17). At that time, I chose to
ignore the exit code of "finish_connect()" without investigating the
root cause of the abnormal termination of git-receive-pack. That was an
incorrect solution.
The root cause is that an atomic push operation terminates early without
sending a flush packet to git-receive-pack. As a result,
git-receive-pack continues waiting for commands without exiting. By
sending a flush packet at the appropriate location in "send_pack()", we
ensure that the git-receive-pack process closes properly, avoiding an
erroneous exit code for git-push. At the same time, revert the changes
to the "transport.c" file made in commit 7dcbeaa0df.

The "push_refs" function in the transport_vtable is the handler for
git-push operation. All the "push_refs" functions for different
transports (protocols) should have the same behavior, but the behavior
of "git_transport_push()" function for builtin_smart_vtable in
"transport.c" (which calls "send_pack()" in "send-pack.c") differs from
the handler of the HTTP protocol.
The "push_refs()" function for the HTTP protocol which calls the
"push_refs_with_push()" function in "transport-helper.c" will return 0
even when a bad REF_STATUS (such as REF_STATUS_REJECT_NONFASTFORWARD)
was found. But "send_pack()" for Git smart protocol will return -1 for
a bad REF_STATUS.
We cannot ignore bad REF_STATUS directly in the "send_pack()" function,
because the function is also used in "builtin/send-pack.c". So we add a
new non-zero error code "SEND_PACK_ERROR_REF_STATUS" for "send_pack()".
Ignore the specific error code in the "git_transport_push()" function to
have the same behavior as "push_refs()" for HTTP protocol. Note that
even though we ignore the error here, we'll ultimately still end up
detecting that a subset of refs was not pushed in `transport_push()`
because we eventually call `push_had_errors()` on the remote refs.

Stop using `the_repository` in the "send-pack" subsystem by passing in a
repository when sending a packfile.
Adjust callers accordingly by using `the_repository`. While there may be
some callers that have a repository available in their context, this
trivial conversion allows for easier verification and bubbles up the use
of `the_repository` by one level.

We have a bunch of loops which iterate up to an unsigned boundary using
a signed index, which generates warnigs because we compare a signed and
unsigned value in the loop condition. Address these sites for trivial
cases and enable `-Wsign-compare` warnings for these code units.
This patch only adapts those code units where we can drop the
`DISABLE_SIGN_COMPARE_WARNINGS` macro in the same step.

Our error reporting routines append a trailing newline, and the strings
we pass to them should not include them (otherwise we get an extra blank
line after the message).
These cases were all found by looking at the results of:
git grep -P '[^_](error|error_errno|warning|die|die_errno)\(.*\\n"[,)]' '*.c'
Note that we _do_ sometimes include a newline in the middle of such
messages, to create multiline output (hence our grep matching "," or ")"
after we see the newline, so we know we're at the end of the string).
It's possible that one or more of these cases could intentionally be
including a blank line at the end, but having looked at them all
manually, I think these are all just mistakes.

When retrieving the push cert nonce from the server, we first store the
constant returned by `server_feature_value()` and then, if the nonce is
valid, we duplicate the nonce memory to a NUL-terminated string, so that
we can pass it to `generate_push_cert()`. We never free the latter and
thus cause a memory leak.
Fix this by storing the limited-lifetime nonce into a scope-local
variable such that the long-lived, allocated nonce can be easily freed
without having to cast away its constness.
This leak was exposed by t5534, but fixing it is not sufficient to make
the whole test suite leak free.

"git push" that pushes only deletion gave an unnecessary and
harmless error message when push negotiation is configured, which
has been corrected.
* jc/disable-push-nego-for-deletion:
push: avoid showing false negotiation errors
|
|
When "git push" is configured to use the push negotiation, a push of
deletion of a branch (without pushing anything else) may end up not
having anything to negotiate for the common ancestor discovery.
In such a case, we end up making an internal invocation of "git
fetch --negotiate-only" without any "--negotiate-tip" parameters
that stops the negotiate-only fetch from being run, which by itself
is not a bad thing (one fewer round-trip), but the end-user sees a
"fatal: --negotiate-only needs one or more --negotiation-tip=*"
message that the user cannot act upon.
Teach "git push" to notice the situation and omit performing the
negotiate-only fetch to begin with. One fewer process spawned, one
fewer "alarming" message given the user.

Use of the `the_repository` variable is deprecated nowadays, and we
slowly but steadily convert the codebase to not use it anymore. Instead,
callers should be passing down the repository to work on via parameters.
It is hard though to prove that a given code unit does not use this
variable anymore. The most trivial case, merely demonstrating that there
is no direct use of `the_repository`, is already a bit of a pain during
code reviews as the reviewer needs to manually verify claims made by the
patch author. The bigger problem though is that we have many interfaces
that implicitly rely on `the_repository`.
Introduce a new `USE_THE_REPOSITORY_VARIABLE` macro that allows code
units to opt into usage of `the_repository`. The intent of this macro is
to demonstrate that a certain code unit does not use this variable
anymore, and to keep it from new dependencies on it in future changes,
be it explicit or implicit
For now, the macro only guards `the_repository` itself as well as
`the_hash_algo`. There are many more known interfaces where we have an
implicit dependency on `the_repository`, but those are not guarded at
the current point in time. Over time though, we should start to add
guards as required (or even better, just remove them).
Define the macro as required in our code units. As expected, most of our
code still relies on the global variable. Nearly all of our builtins
rely on the variable as there is no way yet to pass `the_repository` to
their entry point. For now, declare the macro in "biultin.h" to keep the
required changes at least a little bit more contained.

In `receive_status()`, we record the reason why ref updates have been
rejected by the remote via the `remote_status`. But while we allocate
the assigned string when a reason was given, we assign a string constant
when no reason was given.
This has been working fine so far due to two reasons:
- We don't ever free the refs in git-send-pack(1)'
- Remotes always give a reason, at least as implemented by Git proper.
Adapt the code to always allocate the receive status string and free the
refs.

When parsing server capabilities, we use "int" to store lengths and
offsets. At first glance this seems like a spot where our parser may be
confused by integer overflow if somebody sent us a malicious response.
In practice these strings are all bounded by the 64k limit of a
pkt-line, so using "int" is OK. However, it makes the code simpler to
audit if they just use size_t everywhere. Note that because we take
these parameters as pointers, this also forces many callers to update
their declared types.

cache.h's nature of a dumping ground of includes prevented it from

either. They all can still be built, of course, because they include
one of the header files that does include 'parse-options.h' (though
unnecessarily, see the next commit).
Add those missing includes to these files, as our general rule is that
"a C file must directly include the header files that declare the
functions and the types it uses".

As reported in [1] the "UNUSED(var)" macro introduced in
2174b8c75de (Merge branch 'jk/unused-annotation' into next,
2022-08-24) breaks coccinelle's parsing of our sources in files where
it occurs.
Let's instead partially go with the approach suggested in [2] of
making this not take an argument. As noted in [1] "coccinelle" will
ignore such tokens in argument lists that it doesn't know about, and
it's less of a surprise to syntax highlighters.
This undoes the "help us notice when a parameter marked as unused is
actually use" part of 9b240347543 (git-compat-util: add UNUSED macro,
2022-08-19), a subsequent commit will further tweak the macro to
implement a replacement for that functionality.

The start_async(), etc, functions need a "proc" callback that conforms
to a particular interface. Not every callback needs every parameter
(e.g., the caller might not even ask to open an input descriptor, in
which case there is no point in the callback looking at it). Let's mark
these for -Wunused-parameter.

Reachability bitmaps are designed to speed up the "counting objects"
phase of generating a pack during a clone or fetch. They are not
optimized for Git clients sending a small topic branch via "git push".
In some cases (see [1]), using reachability bitmaps during "git push"
can cause significant performance regressions.
Add a new "push.useBitmaps" configuration variable to allow users to
tell "git push" not to use bitmaps. We already have "pack.bitmaps"
that controls the use of bitmaps, but a separate configuration variable
allows the reachability bitmaps to still be used in other areas,
such as "git upload-pack", while disabling it only for "git push".

Use ssh public crypto for object and push-cert signing.
* fs/ssh-signing:
ssh signing: test that gpg fails for unknown keys
ssh signing: tests for logs, tags & push certs
ssh signing: duplicate t7510 tests for commits
ssh signing: verify signatures using ssh-keygen
ssh signing: provide a textual signing_key_id
ssh signing: retrieve a default key from ssh-agent
ssh signing: add ssh key format and signing code
ssh signing: add test prereqs
ssh signing: preliminary refactoring and clean-up
|
|
For ssh the user.signingkey can be a filename/path or even a literal ssh pubkey.
In push certs and textual output we prefer the ssh fingerprint instead.

Bugfix for common ancestor negotiation recently introduced in "git
push" code path.
* jt/push-negotiation-fixes:
fetch: die on invalid --negotiation-tip hash
send-pack: fix push nego. when remote has refs
send-pack: fix push.negotiate with remote helper
|
|
Commit 477673d6f3 ("send-pack: support push negotiation", 2021-05-05)
did not test the case in which a remote advertises at least one ref. In
such a case, "remote_refs" in get_commons_through_negotiation() in
send-pack.c would also contain those refs with a zero ref->new_oid (in
addition to the refs being pushed with a nonzero ref->new_oid). Passing
them as negotiation tips to "git fetch" causes an error, so filter them
out.
(The exact error that would happen in "git fetch" in this case is a
segmentation fault, which is unwanted. This will be fixed in the
subsequent commit.)

Move the early return if we have no remote refs in send_pack()
earlier.
When this was added in 4c353e890c0 (Warn when send-pack does nothing,
2005-12-04) one of the first things we'd do was to abort, but as of
cfee10a773b (send-pack/receive-pack: allow errors to be reported back
to pusher., 2005-12-25) we've added numerous server_supports()
conditions that are acted on later in the function, that won't be used
if we don't have remote refs.
Then as of 477673d6f39 (send-pack: support push negotiation,
2021-05-04) we started doing even more work on the assumption that we
had some remote refs to feed to --negotiation-tip=* options.
We only hit this condition if we have nothing to push, so we don't
need to consider "push.negotiate" etc. only to do nothing with that
information.
