After going through the "failed" label, load_bitmap() will return -1,
and its caller (either prepare_bitmap_walk() or prepare_bitmap_git())
will then call free_bitmap_index().
That function would have done:
struct stored_bitmap *sb;
kh_foreach_value(b->bitmaps, sb {
ewah_pool_free(sb->root);
free(sb);
});
, but won't since load_bitmap() already called kh_destroy_oid_map() and
NULL'd the "bitmaps" pointer from within its "failed" label. Thus if you
got part of the way through loading bitmap entries and then failed, you
would leak all of the previous entries that you were able to load
successfully.
The solution is to remove the error handling code in load_bitmap(), because
its caller will always call free_bitmap_index() in case of an error.

1. Synopsis: `--value=<value>`

Since df076bdbcc ([PATCH] GIT: Listen on IPv6 as well, if available.,
2005-07-23), the original error checking was included in an inner loop
unchanged, where its effect was different.
Instead of retrying, after a EINTR during accept() in the listening
socket, it will advance to the next one and try with that instead,
leaving the client waiting for another round.
Make sure to retry with the same listener socket that failed originally.
To avoid an unlikely busy loop, fallback to the old behaviour after a
couple of attempts.

To improve support for symbolic port names in netrc files, this
changes does the following:
- Treat symbolic port names as ports, not protocols in git-credential-netrc
- Validate the SMTP server port provided to send-email
- Convert the above symbolic port names to their numerical values.
Before this change, it was not possible to have a SMTP server port set
to "smtps" in a netrc file (e.g. Emacs' ~/.authinfo.gpg), as it would
be registered as a protocol and break the match for a "smtp" protocol
host, as queried for by git-send-email.

In 9d2962a7c4 (receive-pack: use batched reference updates, 2025-05-19)
we updated the 'git-receive-pack(1)' command to use batched reference
updates. One edge case which was missed during this implementation was
when a user pushes multiple branches such as:
delete refs/heads/branch/conflict
create refs/heads/branch
Before using batched updates, the references would be applied
sequentially and hence no conflicts would arise. With batched updates,
while the first update applies, the second fails due to D/F conflict. A
similar issue was present in 'git-fetch(1)' and was fixed by separating
out reference pruning into a separate transaction in the commit 'fetch:
use batched reference updates'. Apply a similar mechanism for
'git-receive-pack(1)' and separate out reference deletions into its own
batch.
This means 'git-receive-pack(1)' will now use up to two transactions,
whereas before using batched updates it would use _at least_ two
transactions. So using batched updates is still the better option.
Add a test to validate this behavior.

The commit 23fc8e4f61 (refs: implement batch reference update support,
2025-04-08) introduced support for batched reference updates. This
allows users to batch updates together, while allowing some of the
updates to fail.
Under the hood, batched updates use the reference transaction mechanism.
Each update which fails is marked as such. Any failed updates must be
skipped over in the rest of the code, as they wouldn't apply any more.
In two of the loops within 'files_transaction_finish()' of the files
backend, the failed updates aren't skipped over. This can cause a
SEGFAULT otherwise. Add the missing skips and a test to validate the
same.

The "seq" tool has a "-f" option to produce printf-style formatted
lines. Let's teach our test_seq helper the same trick. This lets us get
rid of some shell loops in test snippets (which are particularly verbose
in our test suite because we have to "|| return 1" to keep the &&-chain
going).
This converts a few call-sites I found by grepping around the test
suite. A few notes on these:
- In "seq", the format specifier is a "%g" float. Since test_seq only
supports integers, I've kept the more natural "%d" (which is what
these call sites were using already).
- Like "seq", test_seq automatically adds a newline to the specified
format. This is what all callers are doing already except for t0021,
but there we do not care about the exact format. We are just trying
to printf a large number of bytes to a file. It's not worth
complicating other callers or adding an option to avoid the newline
in that caller.
- Most conversions are just replacing a shell loop (which does get rid
of an extra fork, since $() requires a subshell). In t0612 we can
replace an awk invocation, which I think makes the end result more
readable, as there's less quoting.
- In t7422 we can replace one loop, but sadly we have to leave the
loop directly above it. This is because that earlier loop wants to
include the seq value twice in the output, which test_seq does not
support (nor does regular seq). If you run:
test_seq -f "foo-%d %d" 10
the second "%d" will always be the empty string. You might naively
think that test_seq could add some extra arguments, like:
# 3 ought to be enough for anyone...
printf "$fmt\n" "$i "$i" $i"
but that just triggers printf to format multiple lines, one per
extra set of arguments.
So we'd have to actually parse the format string, figure out how
many "%" placeholders are there, and then feed it that many
instances of the sequence number. The complexity isn't worth it.

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.

The repo_get_default_remote() function in submodule--helper currently
tries to figure out the proper remote name to use for a submodule based
on a few factors.
First, it tries to find the remote for the currently checked out branch.
This works if the submodule is configured to checkout to a branch
instead of a detached HEAD state.
In the detached HEAD state, the code calls back to using "origin", on
the assumption that this is the default remote name. Some users may
change this, such as by setting clone.defaultRemoteName, or by changing
the remote name manually within the submodule repository.
As a first step to improving this situation, refactor to reuse the logic
from remotes_remote_for_branch(). This function uses the remote from the
branch if it has one. If it doesn't then it checks to see if there is
exactly one remote. It uses this remote first before attempting to fall
back to "origin".
To allow using this helper function, introduce a repo_default_remote()
helper to remote.c which takes a repository structure. This helper will
load the remote configuration and get the "HEAD" branch. Then it will
call remotes_remote_for_branch to find the default remote.
Replace calls of repo_get_default_remote() with the calls to this new
function. To maintain consistency with the existing callers, continue
copying the returned string with xstrdup.
This isn't a perfect solution for users who change remote names, but it
should help in cases where the remote name is changed but users haven't
added any additional remotes.

The remotes_remote_get_1 (and its caller, remotes_remote_get, have an
implicit dependency on the_repository due to calling
read_branches_file() and read_remotes_file(), both of which use
the_repository. The branch_get() function calls set_merge() which has an
implicit dependency on the_repository as well.
Because of this use of the_repository, the helper functions cannot be
used in code paths which operate on other repositories. A future
refactor of the submodule--helper will want to make use of some of these
functions.
Refactor to break the dependency by passing struct repository *repo
instead of struct remote_state *remote_state in a few places.
The public callers and many other helper functions still depend on
the_repository. A repo-aware function will be exposed in a following
change for git submodule--helper.

Both submodule--helper.c and submodule-config.c have an implementation
of starts_with_dot_slash and starts_with_dot_dot_slash. The dir.h header
has starts_with_dot(_dot)_slash_native, which sets PATH_MATCH_NATIVE.
Move the helpers to dir.h as static inlines. I thought about renaming
them to postfix with _platform but that felt too long and ugly. On the
other hand it might be slightly confusing with _native.
This simplifies a submodule refactor which wants to use the helpers
earlier in the submodule--helper.c file.

The remote_clear() function failed to free the remote->push and
remote->fetch refspec fields.
This should be caught by the leak sanitizer. However, for callers which
use ``the_repository``, the values never go out of scope and the
sanitizer doesn't complain.
A future change is going to add a caller of read_config() for a
submodule repository structure, which would result in the leak sanitizer
complaining.
Fix remote_clear(), updating it to properly call refspec_clear() for
both the push and fetch members.
