The remote-matching logic for submodules has been corrected to resolve
'url.*.insteadOf' aliases before comparing the inventoried URL from
'.gitmodules' with the URLs of configured remotes.

When the push remote is specified as a URL, the fetch refspec of a

The dependency on the global 'the_repository' variable in the

The in-core data structure used to keep track of
'url.<real>.{insteadOf,pushInsteadOf} = <alias>' settings is not
properly cleaned up when the process is done with it.
'struct rewrites' is embedded in 'remote_state' and serves as the
top level of the rewrite data. This holds an array of a variable
number of pointers to 'struct rewrite' allocated individually on the
heap. Each 'struct rewrite' holds a '.base' string and an array of
'struct counted_string' called '.instead_of', which is allocated
contiguously on the heap. Each 'struct counted_string' has a
pointer to a string allocated on the heap.
Amid these pointers, rewrites_release() fails to free everything
other than 'struct rewrite''s '.base' member and the 'struct rewrite'
instances themselves.
Fix rewrites_release() to also free the contiguous array storing
'.instead_of', the string pointers within each '.instead_of' element,
and each 'struct rewrite' instance individually allocated on the heap.

When ca62f524c1 (submodule: look up remotes by URL first, 2025-06-23)
introduced a mechanism to identify which remote is to be used by a
submodule, it compared the URL stored in the .gitmodules inventory to
that of each available remote.
The URLs of remotes are rewritten according to url.<base>.insteadOf,
whereas those stored in the .gitmodules aren't. When such aliasing
applies, no match can be made between the two corresponding sides, and
the procedure degrades to its fallback logic electing either the only
configured remote if there is only one, or "origin" otherwise.
That behaviour is unfortunate when no remote is called "origin",
because its last resort will have a submodule update command look for a
non-existent remote-tracking reference and fail to proceed, instead of
using the remote whose rewritten URL matches.
Resolve the alias in the URL inventoried in .gitmodules before comparing
it against those of the corresponding submodule's configured remotes.

Git accepts a repository URL as branch.<name>.pushRemote and can push
to it. This branch setting takes precedence over remote.pushDefault.
A branch can be configured with a URL-valued pushRemote before any push
occurs. If the remotes are later rearranged with "git remote rename" and
"git remote add", the newly added remote may use that URL. The URL value
is unaffected by the rename and continues to take precedence over
remote.pushDefault. The URL and the remote then point to the same
repository, but Git does not connect them for tracking. Pushing works,
but @{push} cannot identify the remote's tracking branch. As a result,
"git status" cannot show the push branch, and an up-to-date push can
leave its tracking information stale.
When exactly one configured remote would push to the same URL, use that
remote for push tracking. Continue to push to the URL so the configured
remote's push settings do not change existing behavior. Keep the current
behavior when no remote matches or multiple remotes match.

The only remaining user of `the_hash_algo` in "refspec.c" is
`refspec_append()`, which needs to know the hash algorithm so that it
can parse the appended refspec item. In contrast to the functions
adapted in the preceding commit, this function always operates on a
`struct refspec`. As that structure is expected to only ever contain
refspecs that all use the same hash function it doesn't make sense
though to adapt each caller.
Instead, adapt the structure itself so that it gets initialized with a
hash function and use that hash function to parse new refspec items.
Adapt callers accordingly.
This removes the final dependency on the global repository variable in
"refspec.c", so we can drop `USE_THE_REPOSITORY_VARIABLE`.

When parsing a refspec item we need to know about the hash algorithm
used by the repository so that we can decide whether or not a given
string is an exact object ID. We use `the_hash_algo` for this, which
makes the code implicitly depend on `the_repository`.
Refactor `refspec_item_init_fetch()`, `refspec_item_init_push()` and
`valid_fetch_refspec()` so that callers have to pass in the hash
algorithm explicitly and adapt callers accordingly. For now, all of
the callers simply pass `the_hash_algo`, so there is no change in
behaviour.

The global variable 'push_default' specifies the default behavior of
'git push' when no explicit refspec is provided. Move 'push_default'
into 'struct repo_config_values' to continue the libification effort.
While 'enum push_default_type' ideally belongs in 'remote.h', moving it
there introduces a circular dependency chain:
remote.h -> hash.h -> repository.h -> environment.h.
Therefore, the enum definition is kept in 'environment.h' just above
'struct repo_config_values' with a NEEDSWORK comment for future cleanup.
Modify the configuration parsing in environment.c to update the
per-repository structure directly, and update caller across the
codebase to access the value via 'repo_config_values()'.

The `remote_tracking()` function unconditionally dereferences
`remote->fetch` without checking whether remote is NULL.
In practice, this never happens because the only caller (`apply_cas()`)
guards the calls to this function by checking the `use_tracking` and
`use_tracking_for_rest` attributes.
However, it requires quite involved reasoning to reach that conclusion,
and is therefore fragile. Just return -1 ("no tracking ref") when there
is no remote to work with.

Add a new 'remote.<name>.negotiationInclude' multi-valued config option that
provides default values for --negotiation-include when no
--negotiation-include arguments are specified over the command line. This
is a mirror of how 'remote.<name>.negotiationRestrict' specifies defaults
for the --negotiation-restrict arguments.
Each value is either an exact ref name or a glob pattern whose tips should
always be sent as 'have' lines during negotiation. The config values are
resolved through the same resolve_negotiation_include() codepath as the CLI
options.
This option is additive with the normal negotiation process: the negotiation
algorithm still runs and advertises its own selected commits, but the refs
matching the config are sent unconditionally on top of those heuristically
selected commits.
Similar to the negotiationRestrict config, an empty value resets the value
list to allow ignoring earlier config values, such as those that might be
set in system or global config.

In a previous change, the --negotiation-restrict command-line option of 'git
fetch' was added as a synonym of --negotiation-tip. Both of these options
restrict the set of 'haves' the client can send as part of negotiation.
This was previously not available via a configuration option. Add a new
'remote.<name>.negotiationRestrict' multi-valued config option that updates
'git fetch <name>' to use these restrictions by default.
If the user provides even one --negotiation-restrict argument, then the
config is ignored.

`get_remote_group`, `add_remote_or_group`, and the `remote_group_data`
struct are currently defined as static helpers inside builtin/fetch.c.
They implement generic remote group resolution that is not specific to
fetch — they parse `remotes.<name>` config entries and resolve a name
to either a list of group members or a single configured remote.
Move them to remote.c and declare them in remote.h so that other
builtins can use the same logic without duplication.
Useful for the next patch.

Add a new configuration variable status.compareBranches that allows
users to specify a space-separated list of branch comparisons in
git status output.
Supported values:
- @{upstream} for the current branch's upstream tracking branch
- @{push} for the current branch's push destination
Any other value is ignored and a warning is shown.
When not configured, the default behavior is equivalent to setting
`status.compareBranches = @{upstream}`, preserving backward
compatibility.
The advice messages shown are context-aware:
- "git pull" advice is shown only when comparing against @{upstream}
- "git push" advice is shown only when comparing against @{push}
- Divergence advice is shown for upstream branch comparisons
This is useful for triangular workflows where the upstream tracking
branch differs from the push destination, allowing users to see their
status relative to both branches at once.

compareBranches = @{upstream} @{push}

In branch_get_push(), we usually allocate a new string for the @{push}
ref, but will not do so in push.default=upstream mode, where we just
pass back the result of branch_get_upstream() directly.
This led to a hacky memory management scheme in e291c75a95 (remote.c:
add branch_get_push, 2015-05-21): we store the result in the
push_tracking_ref field of a "struct branch", under the assumption that
the branch struct will last until the end of the program. So even though
the struct doesn't know if it has an allocated string or not, it doesn't
matter because we hold on to it either way.
But that assumption was violated by f5ccb535cc (remote: fix leaking
config strings, 2024-08-22), which added a function to free branch
structs. Any struct which is fed to branch_release() is at risk of
leaking its push_tracking_ref member.
I don't think this can actually be triggered in practice. We rarely
actually free the branch structs, and we only fill in the
push_tracking_ref string lazily when it is needed. So triggering the
leak would require a code path that does both, and I couldn't find one.
Still, this is an ugly trap that may eventually spring on us. Since
there is only one code path in branch_get_push() that doesn't allocate,
let's just have it copy the string. And then we know that
push_tracking_ref is always allocated, and we can free it in
branch_release().

Most of the code paths in branch_get_push_1() allocate a string for the
@{push} value. We then return the result, which is stored in a "struct
branch", so the value is not leaked.
But there's one path that does leak: when we are in the "simple" push
mode, we have to check that the @{push} value matches what we'd get for
@{upstream}. If it doesn't, we return an error, but forget to free the
@{push} value we computed.
Curiously, the existing tests don't trigger this with LSan, even though
they do exercise the code path. As far as I can tell, it should be
triggered via:
git -c push.default=simple \
-c branch.foo.remote=origin \
-c branch.foo.merge=refs/heads/not-foo \
rev-parse foo@{push}
which will complain that the upstream ("not-foo") does not match the
push destination ("foo"). We do die() shortly after this, but not until
after returning from branch_get_push_1(), which is where the leak
happens.
So it seems like a false negative in LSan. However, I can trigger it
reliably by printing the @{push} value using for-each-ref. This takes a
little more setup (because we need "foo" to actually exist to iterate
over it with for-each-ref), but we can piggy-back on the existing repo
config in t6300.

The string returned from tracking_for_push_dest() comes from
apply_refspec(), and thus is always an allocated string (or NULL). We
should return a non-const pointer so that the caller knows that
ownership of the string is being transferred.
This goes back to the function's origin in e291c75a95 (remote.c: add
branch_get_push, 2015-05-21). It never really mattered because our
return is just forwarded through branch_get_push_1(), which returns a
const string as part of an intentionally hacky memory management scheme
(see that commit for details).
As the first step of untangling that hackery, let's drop the extra const
from this helper function (and from the variables that store its
result). There should be no functional change (yet).

We have an error_buf() helper that functions a bit like our error()
helper, but returns NULL instead of -1. Its return type is "const char
*", but this is overly restrictive. If we use the helper in a function
that returns non-const "char *", the compiler will complain about
the implicit cast from const to non-const.
Meanwhile, the const in the helper is doing nothing useful, as it only
ever returns NULL. Let's drop the const, which will let us use it in
both types of function.

Our coding guidelines say that:
Functions that operate on `struct S` are named `S_<verb>()` and should
generally receive a pointer to `struct S` as first parameter.
While most of the functions related to `struct commit_list` already
follow that naming schema, `free_commit_list()` doesn't.
Rename the function to address this and adjust all of its callers. Add a
compatibility wrapper for the old function name to ease the transition
and avoid any semantic conflicts with in-flight patch series. This
wrapper will be removed once Git 2.53 has been released.

The `each_ref_fn` callback function type is used across our code base
for several different functions that iterate through reference. There's
a bunch of callbacks implementing this type, which makes any changes to
the callback signature extremely noisy. An example of the required churn
is e8207717f1 (refs: add referent to each_ref_fn, 2024-08-09): adding a
single argument required us to change 48 files.
It was already proposed back then [1] that we might want to introduce a
wrapper structure to alleviate the pain going forward. While this of
course requires the same kind of global refactoring as just introducing
a new parameter, it at least allows us to more change the callback type
afterwards by just extending the wrapper structure.
One counterargument to this refactoring is that it makes the structure
more opaque. While it is obvious which callsites need to be fixed up
when we change the function type, it's not obvious anymore once we use
a structure. That being said, we only have a handful of sites that
actually need to populate this wrapper structure: our ref backends,
"refs/iterator.c" as well as very few sites that invoke the iterator
callback functions directly.
Introduce this wrapper structure so that we can adapt the iterator
interfaces more readily.

There are double frees and leaks around setup_revisions() API used
in "git stash show", which has been fixed, and setup_revisions()
API gained a wrapper to make it more ergonomic when using it with
strvec-manged argc/argv pairs.
* jk/setup-revisions-freefix:
revision: retain argv NULL invariant in setup_revisions()
treewide: pass strvecs around for setup_revisions_from_strvec()
treewide: use setup_revisions_from_strvec() when we have a strvec
revision: add wrapper to setup_revisions() from a strvec
revision: manage memory ownership of argv in setup_revisions()
stash: tell setup_revisions() to free our allocated strings
|
|
The setup_revisions() function was designed to take the argc/argv pair
from the operating system. But we sometimes construct our own argv using
a strvec and pass that in. There are a few gotchas that callers need to
deal with here:
1. You should always pass the free_removed_argv_elements option via
setup_revision_opt. Otherwise, entries may be leaked if
setup_revisions() re-shuffles options.
2. After setup_revisions() returns, the strvec state is odd. We get a
reduced argc from setup_revisions() telling us how many unknown
options were left in place. Entries after that in argv may be
retained, or may be NULL (depending on how the reshuffling
happened). But the strvec's "nr" field still represents the
original value, and some of the entries it thinks it is still
storing may be NULL. Callers must be careful with how they access
it.
Some callers deal with (1), but not all. In practice they are OK because
they do not pass any options that would cause setup_revisions() to
re-shuffle (namely unknown options which may be relayed from the user,
and the use of the "--" separator). But it's probably a good idea to
consistently pass this option anyway to future-proof ourselves against
the details of setup_revisions() changing.
No callers address (2), though I don't think there any visible bugs.
Most of them simply call strvec_clear() and never otherwise look at the
result. And in fact, if they naively set foo.nr to the argc returned by
setup_revisions(), that would cause leaks! Because setup_revisions()
does not free consumed options[1], we have to leave the "nr" field of
the strvec at its original value to find and free them during
strvec_clear().
So I don't think there are any bugs to fix here, but we can make things
safer and simpler for callers. Let's introduce a helper function that
sets the free_removed_argv_elements automatically and shrinks the strvec
to represent the retained options afterwards (taking care to free the
now-obsolete entries).
We'll start by converting all of the call-sites which use the
free_removed_argv_elements option. There should be no behavior change
for them, except that their "shrunken" entries are cleaned up
immediately, rather than waiting for a strvec_clear() call.
[1] Arguably setup_revisions() should be doing this step for us if we
told it to free removed options, but there are many existing callers
which will be broken if it did. Introducing this helper is a
possible first step towards that.

When "git push <remote> <src>:<dst>" does not spell out the
destination side of the ref fully, and when <src> is not given
as a reference but an object name, the code tries to give advice
messages based on the type of that object.
The type is determined by calling odb_read_object_info() and
signalled by its return value. The code however reported a
programming error with BUG() when this function said that there
is no such object, which happens when the object name is given
as a full hexadecimal (if the object name is given as a partial
hexadecimal or an non-existing ref, the function would have died
without returning, so this BUG() wouldn't have triggered). This
is wrong. It is an ordinary end-user mistake to give an object
name that does not exist and treated as such.
An example of the error message produced is as follows:
error: The destination you provided is not a full refname (i.e.,
starting with "refs/"). We tried to guess what you meant by:
- Looking for a ref that matches 'branch' on the remote side.
- Checking if the <src> being pushed ('0000000000000000000000000000000000000001')
is a ref in "refs/{heads,tags}/". If so we add a corresponding
refs/{heads,tags}/ prefix on the remote side.
Neither worked, so we gave up. You must fully qualify the ref.

With `refs_for_each_reflog_ent()` callers can iterate through all the
reflog entries for a given reference. The callback that is being invoked
for each such entry does not receive the name of the reference that we
are currently iterating through. This isn't really a limiting factor, as
callers can simply pass the name via the callback data.
But this layout sometimes does make for a bit of an awkward calling
pattern. One example: when iterating through all reflogs, and for each
reflog we iterate through all refnames, we have to do some extra book
keeping to track which reference name we are currently yielding reflog
entries for.
Change the signature of the callback function so that the reference name
of the reflog gets passed through to it. Adapt callers accordingly and
start using the new parameter in trivial cases. The next commit will
refactor the reference migration logic to make use of this parameter so
that we can simplify its logic a bit.

In 036876a1067 (config: hide functions using `the_repository` by
default, 2024-08-13) we have moved around a bunch of functions in the
config subsystem that depend on `the_repository`. Those function have
been converted into mere wrappers around their equivalent function that
takes in a repository as parameter, and the intent was that we'll
eventually remove those wrappers to make the dependency on the global
repository variable explicit at the callsite.
Follow through with that intent and remove `git_config_get_string()`.
All callsites are adjusted so that they use
`repo_config_get_string(the_repository, ...)` instead. While some
callsites might already have a repository available, this mechanical
conversion is the exact same as the current situation and thus cannot
cause any regression. Those sites should eventually be cleaned up in a
later patch series.

Rename `has_object()` to `odb_has_object()` to match other functions
related to the object database and our modern coding guidelines.
Introduce a compatibility wrapper so that any in-flight topics will
continue to compile.

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 get_default_remote_submodule() function performs a lookup to find
the appropriate remote to use within a submodule. The function first
checks to see if it can find the remote for the current branch. If this
fails, it then checks to see if there is exactly one remote. It will use
this, before finally falling back to "origin" as the default.
If a user happens to rename their default remote from origin, either
manually or by setting something like clone.defaultRemoteName, this
fallback will not work.
In such cases, the submodule logic will try to use a non-existent
remote. This usually manifests as a failure to trigger the submodule
update.
The parent project already knows and stores the submodule URL in either
.gitmodules or its .git/config.
Add a new repo_remote_from_url() helper which will iterate over all the
remotes in a repository and return the first remote which has a matching
URL.
Refactor get_default_remote_submodule to find the submodule and get its
URL. If a valid URL exists, first try to obtain a remote using the new
repo_remote_from_url(). Fall back to the repo_default_remote()
otherwise.
The fallback logic is kept in case for some reason the user has manually
changed the URL within the submodule. Additionally, we still try to use
a remote rather than directly passing the URL in the
fetch_in_submodule() logic. This ensures that an update will properly
update the remote refs within the submodule as expected, rather than
just fetching into FETCH_HEAD.
