Refactor builtin/prune.c to remove the dependency on the global
'the_repository'. Replace all the occurrences of 'the_repository' with
repo and thus remove the definition '#define
USE_THE_REPOSITORY_VARIABLE'. Also, add a test to make sure that 'git
prune -h' can be called when the repository is `NULL`.

The 'extensions.preciousObjects' setting when set true, prevents
operations that might drop objects from the object storage. This setting
is populated in the global variable
'repository_format_precious_objects'.
Move this global variable to repo scope by adding it to 'struct
repository and also refactor all the occurences accordingly.
This change is part of an ongoing effort to eliminate global variables,
improve modularity and help libify the codebase.

We use "test-tool string-list remove_duplicates" to test the
"string_list_remove_duplicates" function. As we have introduced the unit
test, we'd better remove the logic from shell script to C program to
improve test speed and readability.
As all the tests in shell script are removed, let's just delete the
"t0063-string-list.sh" and update the "meson.build" file to align with
this change.
Also we could simply remove "DISABLE_SIGN_COMPARE_WARNINGS" due to we
have already deleted related code.
Unfortunately, we cannot totally remove "test-string-list.c" due to that
we would test the performance of sorting about string list by executing
"test-tool string-list sort" in "p0071-sort.sh".

We rely on "test-tool string-list" command to test the functionality of
the "string-list". However, as we have introduced clar test framework,
we'd better move the shell script into C program to improve speed and
readability.
Create a new file "u-string-list.c" under "t/unit-tests", then update
the Makefile and "meson.build" to build the file. And let's first move
"test_split" into unit test and gradually convert the shell script into
C program.
In order to create `string_list` easily by simply specifying strings in
the function call, create "t_vcreate_string_list_dup" function to do
this.
Then port the shell script tests to C program and remove unused
"test-tool" code and tests.

In "add_entry", we call "get_entry_index" function to get the inserted
position. However, as the return type of "get_entry_index" function is
`int`, there is a sign compare warning when comparing the `index` with
the `list-nr` of unsigned type.
"get_entry_index" would always return unsigned index. However, the
current binary search algorithm initializes "left" to be "-1", which
necessitates the use of signed `int` return type.
The reason why we need to assign "left" to be "-1" is that in the
`while` loop, we increment "left" by 1 to determine whether the loop
should end. This design choice, while functional, forces us to use
signed arithmetic throughout the function.
To resolve this sign comparison issue, let's modify the binary search
algorithm with the following approach:
1. Initialize "left" to 0 instead of -1
2. Use `left < right` as the loop termination condition instead of
`left + 1 < right`
3. When searching the right part, set `left = middle + 1` instead of
`middle`
Then, we could delete "#define DISABLE_SIGN_COMPARE_WARNING" to enable
sign warnings check for "string-list".

When inserting an existing element, "add_entry" would convert "index"
value to "-1-index" to indicate the caller that this element is in the
list already. However, in "string_list_insert", we would simply convert
this to the original positive index without any further action.
In 8fd2cb4069 (Extract helper bits from c-merge-recursive work,
2006-07-25), we create "path-list.c" and then introduce above code path.
Let's directly return the index as we don't care about whether the
element is in the list by using "add_entry". In the future, if we want
to let "add_entry" tell the caller, we may add "int *exact_match"
parameter to "add_entry" instead of converting the index to negative to
indicate.

In "add_entry", we accept "insert_at" parameter which must be either -1
(auto) or between 0 and `list->nr` inclusive. Any other value is
invalid. When caller specify any invalid "insert_at" value, we won't
check the range and move the element, which would definitely cause the
trouble.
However, we only use "add_entry" in "string_list_insert" function and we
always pass the "-1" for "insert_at" parameter. So, we never use this
parameter to insert element in a user specified position.
And we should know why there is such code path in the first place. We
used to have another function "string_list_insert_at_index()", which
uses the extra "insert_at" parameter. And in f8c4ab611a (string_list:
remove string_list_insert_at_index() from its API, 2014-11-24), we
remove this function but we don't clean all the code path.
Let's simply delete this parameter as we'd better use "strmap" for such
functionality.

indicate that writing the index to disk failed.
However, callers do not use this information. Commands such as stash print

Test that applying a new file creation patch with --intent-to-add to
an existing index does not modify the index outside adding the correct
intents-to-add, and that applying a patch with both modifications
and new file creations with --intent-to-add correctly only adds
intents-to-add to the index.

In the "apply only to files" mode (i.e., neither --index nor --cached
mode), the index should not be touched except to record intents to
add when --intent-to-add is on. Because having --intent-to-add on sets
update_index, to indicate that we may touch the index, we can't rely
only on that flag in create_file() (which is called to write both new
files and updated files) to decide whether to write an index entry;
if we did, we would write an index entry for every file being patched
(which would moreover be an intent-to-add entry despite not being a
new file, because we are going to turn on the CE_INTENT_TO_ADD flag
in add_index_entry() if we enter it here and ita_only is true).
To decide whether to touch the index, we need to check the
specific reason the index would be updated, rather than merely
their aggregate in the update_index flag. Because we have already
entered write_out_results() and are performing writes, we know that
state->apply is true. If state->check_index is additionally true, we
are in --index or --cached mode, which updates the index and should
always write, whereas if we are merely in ita_only mode we must only
write if the patch is a new file creation patch.

There are three main modes of operation for apply: applying only to the
worktree, applying to the worktree and index (--index), and applying
only to the index (--cached).
The --intent-to-add flag modifies the first of these modes, applying
only to the worktree, in a way which touches the index, because intents
to add are special index entries. However, since its introduction
in cff5dc09ed (apply: add --intent-to-add, 2018-05-26), it has not
worked correctly in any but the most trivial (empty repository)
cases, because the index is never read in (in apply, this is done in
read_apply_cache()) before writing to it.
This causes the operation to clobber the old, correct index with a
new empty-tree index before writing intent-to-add entries to this
empty index; the final result is that the index now records every
existing file in the repository as deleted, which is incorrect.
This error can be corrected by first reading the index. The
update_index flag is correctly set if ita_only is true, because this
flag causes the index to be updated. However, if we merely gate the
call to read_apply_cache() behind update_index, then it will not be
read when state->apply is false, even if it must be checked due to
being in --index or --cached mode. Therefore, we instead read the
index if it will be either checked or updated, because reading the
index is a prerequisite to either.

When the user gives us a diff filter like --diff-filter=D, we need to do
a tree diff even if we're not planning to show the diff result itself,
in order to decide whether to show the commit at all. So there's an
explicit check of revs->diffopt.filter in setup_revisions(), and we set
revs->diff if any bits are set.
Originally that "filter" field covered both positive capital-letter
filters (like "D") and also negative lowercase filters (like "d"), so it
was sufficient for both cases. But later, 75408ca949 (diff-filter: be
more careful when looking for negative bits, 2022-01-28) split the
negative bits out into a "filter_not" field.
We eventually fold those into "filter", but not until diff_setup_done()
is called, which happens after our explicit check. As a result, a purely
negative filter like:
git log --diff-filter=d
failed to turn on diffs at all. But rather than fail to filter by diff,
because the filter variable is eventually set, we mistakenly show no
commits at all, thinking that the empty diffs were cases where nothing
passed through the filter.
The smallest fix here is to just have our check look for any bits in
either "filter" or "filter_not". I suspect it would also be OK to
reorder the function a bit to call diff_setup_done() earlier, but that
risks violating some other subtle ordering dependency. So I went with
the simple and safe solution here.

With the preceding commit we have announced the switch to the "reftable"
format in Git 3.0 for newly created repositories. The format is being
battle tested by GitLab and a couple of other developers, and except for
a small handful of issues exposed early after it has been merged it has
been rock solid. Regardless of that though the test user base is still
comparatively small, which increases the risk that we miss critical
bugs.
Address this by enabling the reftable format when experimental features
are enabled. This should increase the test user base by some margin and
thus give us more input before making the format the default.

The "reftable" format has come a long way and has matured nicely since
it has been merged into git via 57db2a094d5 (refs: introduce reftable
backend, 2024-02-07). It fixes longstanding issues that cannot be fixed
with the "files" format in a backwards-compatible way and performs
significantly better in many use cases.
Announce that we will switch to the "reftable" format in Git 3.0 for
newly created repositories and wire up the change, hidden behind the
WITH_BREAKING_CHANGES preprocessor define.
This switch is dependent on support in the larger Git ecosystem. Most
importantly, libraries like JGit, libgit2 and Gitoxide should support
the reftable backend so that we don't break all applications and tools
built on top of those libraries.

FreeBSD 6 introduced memmem(), but the implementation diverged
from what was standard everywhere else (including our "compat"
fallback).
FreeBSD 10.4 (went EOL in 2018) corrected the functionality bugs
but kept a suboptimal implementation until FreeBSD 11.4 (the last
version of FreeBSD 11, that went EOL in September 2021).
Let's draw the line to require FreeBSD 12 or newer, which allows us
to drop the special casing of FreeBSD 4.x and rely on the platform
implementation of memmem() unconditionally for all versions that are
still being supported.

When clang-format was introduced to the Git project in
6134de6ac1 (clang-format: outline the git project's coding style,
2017-08-14), the 'ColumnLimit' was set to 80. This is inline with our
recommendation in 'Documentation/CodingGuidelines', which states:
We try to keep to at most 80 characters per line.
However while this is recommended limit, this is not the enforced
limit. In some cases in we do overflow this limit to prioritize
readability. Setting the 'ColumnLimit' also means that shorter lines are
concatenated to simply as the result would still be below 80 characters,
which is undesirable.
In the past, we tried to adjust the penalties around line wrapping, once
in 42efde4c29 (clang-format: adjust line break penalties, 2017-09-29)
and another time in 5e9fa0f9fa (clang-format: re-adjust line break
penalties, 2024-10-18). While these settings help tweak the line break
penalties to be more in-line with the requirements of the Git project,
using 'clang-format' still produces a lot of false positives.
So to make 'clang-format' more usable, set the 'ColumnLimit' to 0. This
means that line-wrapping is no-longer a concern of the formatter and
something that the user needs to take care of. The previous commit also
added a more flexible guideline to the '.editorconfig' setting a
'max_line_length' of 120 characters. This should provide some guidance
to users.
In the future, it would be nice to re-instate this limit with adequate
penalties which would follow our guidelines, but currently, it makes
more sense to have a working formatter which we can rely on and which
doesn't create too many false positives.

The refs_warn_dangling_symrefs interface is a bit fragile as it passes
in printf-formatting strings with expectations about the number of

argument. But there are only two call sites, and they both use almost
identical display options.
Make this safer by moving the format strings into the function that uses

When pruning during `git fetch` we check each pruned ref against the
ref_store one at a time to decide whether to report it as dangling.
This causes every local ref to be scanned for each ref being pruned.
If there are N refs in the repo and M refs being pruned, this code is
O(M*N). However, `git remote prune` uses a very similar function that
is only O(N*log(M)).
Remove the wasteful ref scanning for each pruned ref and use the faster
version already available in refs_warn_dangling_symrefs. Change the
message to include the original refname since the message is no longer
printed immediately after the line that did just print the refname.
In a repo with 126,000 refs, where I was pruning 28,000 refs, this
code made about 3.6 billion calls to strcmp and consumed 410 seconds
of CPU. (Invariably in that time, my remote would timeout and the
fetch would fail anyway.)
After this change, the same operation completes in under a second.

Our document on breaking changes indicates that we intend to default to
SHA-256 in Git 3.0. Since most people choose the default option, this
is an important security upgrade to our defaults.
To allow people to test this case, when WITH_BREAKING_CHANGES is set in

the testsuite to use the build options information to automatically

Note that if the command substitution for GIT_TEST_BUILTIN_HASH fails,

Right now, the default compile-time hash is SHA-1. However, in the
future, this might change and it would be helpful to gracefully handle
this case in our testsuite.
To avoid making these assumptions, let's introduce a variable that
contains the built-in default hash and use it in our setup code as the
fallback value if no hash was explicitly set. For now, this is always
SHA-1, but in a future commit, we'll allow adjusting this and the
variable will be more useful.
To allow us to make our tests more robust, allow test_oid to take the
--hash=builtin option to specify this hash, whatever it is.
Additionally, add a DEFAULT_HASH_ALGORITHM prerequisite to check for the

When we define a new repository format with REPOSITORY_FORMAT_INIT, we
always use GIT_HASH_SHA1, and this value ends up getting used as the
default value to initialize a repository if none of the command line,
environment, or config tell us to do otherwise.
Because we might not always want to use SHA-1 as the default, let's
instead specify the default hash algorithm constant so that we will use
whatever the specified default is.
However, we also need to continue to read older repositories. If we're
in a v0 repository or extensions.objectformat is not set, then we must
continue to default to the original hash algorithm: SHA-1. If an
algorithm is set explicitly, however, it will override the hash_algo
member of the repository_format struct and we'll get the right value.
Similarly, if the repository was initialized before Git 0.99.3, then it
may lack a core.repositoryformatversion key, and some repositories lack
a config file altogether. In both cases, format->version is -1 and we
need to assume that SHA-1 is in use.
Because clear_repository_format reinitializes the struct
repository_format and therefore sets the hash_algo member to the default
(which could in the future not be SHA-1), we need to reset this member
explicitly. We know, however, that at the point we call
read_repository_format, we are actually reading an existing repository
and not initializing a new one or operating outside of a repository, so
we are not changing the default behavior back to SHA-1 if the default
algorithm is different.
It is potentially questionable that we ignore all repository
configuration if there is a config file but it doesn't have
core.repositoryformatversion set, in which case we reset all of the
configuration to the default. However, it is unclear what the right
thing to do instead with such an old repository is and a simple git init
will add the missing entry, so for now, we simply honor what the
existing code does and reset the value to the default, simply adding our
initialization to SHA-1.

repository's hash algorithm as a default since it doesn't exist, so
instead, let's pick the default instead of specifically SHA-1. Right
now this results in no functional change since the default is SHA-1, but
that may change in the future.

We have a a variety of uses of GIT_HASH_SHA1 littered throughout our
code. Some of these really mean to represent specifically SHA-1, but
some actually represent the original hash algorithm used in Git which is
implied by older, legacy formats and protocols which do not contain hash
information. For instance, the bundle v1 and v2 formats do not contain
hash algorithm information, and thus SHA-1 is implied by the use of
these formats.
Add a constant for documentary purposes which indicates this value. It
will always be the same as SHA-1, since this is an essential part of
these formats, but its use indicates this particular reason and not any
other reason why SHA-1 might be used.

Right now, SHA-1 is the default hash algorithm in Git. However, this
may change in the future.
We have many places in our code that use the SHA-1 constant to indicate
the default hash if none is specified, but it will end up being more
practical to specify this explicitly and clearly using a constant for
whatever the default hash algorithm is. Then, if we decide to change it
in the future, we can simply replace the constant representing the
default with a new value.
For these reasons, introduce GIT_HASH_DEFAULT to represent the default
hash algorithm.

The "--recursive" flag for git-grep(1) allows users to grep for a string
across submodule boundaries. To make this work we add each submodule's
object sources to our own object database so that the objects can be
accessed directly.
The infrastructure for this depends on a global string list of submodule
paths. The caller is expected to call `add_submodule_odb_by_path()` for
each source and the object database will then eventually register all
submodule sources via `do_oid_object_info_extended()` in case it isn't
able to look up a specific object.
This reliance on global state is of course suboptimal with regards to
our libification efforts.
Refactor the logic so that the list of submodule sources is instead
tracked in the object database itself. This allows us to lose the
condition of `r == the_repository` before registering submodule sources
as we only ever add submodule sources to `the_repository` anyway. As
such, behaviour before and after this refactoring should always be the
same.
Rename the functions accordingly.

In subsequent commits we'll get rid of our use of `the_repository` in
"odb.c" in favor of explicitly passing in a `struct object_database` or
a `struct odb_source`. In some cases though we'll need access to the
repository, for example to read a config value from it, but we don't
have a way to access the repository owning a specific object database.
Introduce parent pointers for `struct object_database` to its owning
repository as well as for `struct odb_source` to its owning object
database, which will allow us to adapt those use cases.
Note that this change requires us to pass through the object database to
`link_alt_odb_entry()` so that we can set up the parent pointers for any
source there. The callchain is adapted to pass through the object
database accordingly.

The `object_directory` structure is used as an access point for a single
object directory like ".git/objects". While the structure isn't yet
fully self-contained, the intent is for it to eventually contain all
information required to access objects in one specific location.
While the name "object directory" is a good fit for now, this will
change over time as we continue with the agenda to make pluggable object
databases a thing. Eventually, objects may not be accessed via any kind
of directory at all anymore, but they could instead be backed by any
kind of durable storage mechanism. While it seems quite far-fetched for
now, it is thinkable that eventually this might even be some form of a
database, for example.
As such, the current name of this structure will become worse over time
as we evolve into the direction of pluggable ODBs. Immediate next steps
will start to carve out proper self-contained object directories, which
requires us to pass in these object directories as parameters. Based on
our modern naming schema this means that those functions should then be
named after their subsystem, which means that we would start to bake the
current name into the codebase more and more.
Let's preempt this by renaming the structure. There have been a couple
alternatives that were discussed:
- `odb_backend` was discarded because it led to the association that
one object database has a single backend, but the model is that one
alternate has one backend. Furthermore, "backend" is more about the
actual backing implementation and less about the high-level concept.
- `odb_alternate` was discarded because it is a bit of a stretch to
also call the main object directory an "alternate".
Instead, pick `odb_source` as the new name. It makes it sufficiently
clear that there can be multiple sources and does not cause confusion
when mixed with the already-existing "alternate" terminology.
In the future, this change allows us to easily introduce for example a
`odb_files_source` and other format-specific implementations.

The `raw_object_store` structure is the central entry point for reading
and writing objects in a repository. The main purpose of this structure
is to manage object directories and provide an interface to access and
write objects in those object directories.
Right now, many of the functions associated with the raw object store
implicitly rely on `the_repository` to get access to its `objects`
pointer, which is the `raw_object_store`. As we want to generally get
rid of using `the_repository` across our codebase we will have to
convert this implicit dependency on this global variable into an
explicit parameter.
This conversion can be done by simply passing in an explicit pointer to
a repository and then using its `->objects` pointer. But there is a
second effort underway, which is to make the object subsystem more
selfcontained so that we can eventually have pluggable object backends.
As such, passing in a repository wouldn't make a ton of sense, and the
goal is to convert the object store interfaces such that we always pass
in a reference to the `raw_object_store` instead.
This will expose the `raw_object_store` type to a lot more callers
though, which surfaces that this type is named somewhat awkwardly. The
"raw_" prefix makes readers wonder whether there is a non-raw variant of
the object store, but there isn't. Furthermore, we nowadays want to name
functions in a way that they can be clearly attributed to a specific
subsystem, but calling them e.g. `raw_object_store_has_object()` is just
too unwieldy, even when dropping the "raw_" prefix.
Instead, rename the structure to `object_database`. This term is already
used a lot throughout our codebase, and it cannot easily be mistaken for
"object directories", either. Furthermore, its acronym ODB is already
well-known and works well as part of a function's name, like for example
`odb_has_object()`.

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.

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.

of starts_with_dot_slash and starts_with_dot_dot_slash. The dir.h header

Move the helpers to dir.h as static inlines. I thought about renaming

The branch structure has both branch->merge_name and branch->merge for
tracking the merge information. The former is allocated by add_merge()
and stores the names read from the configuration file. The latter is
allocated by set_merge() which is called by branch_get() when an
external caller requests a branch.
This leads to the confusing situation where branch->merge_nr tracks both
the size of branch->merge (once its allocated) and branch->merge_name.
The branch_release() function incorrectly assumes that branch->merge is
always set when branch->merge_nr is non-zero, and can potentially crash
if read_config() is called without branch_get() being called on every
branch.
In addition, branch_release() fails to free some of the memory
associated with the structure including:
* Failure to free the refspec_item containers in branch->merge[i]
* Failure to free the strings in branch->merge_name[i]
* Failure to free the branch->merge_name parent array.
The set_merge() function sets branch->merge_nr to 0 when there is no
valid remote_name, to avoid external callers seeing a non-zero merge_nr
but a NULL merge array. This results in failure to release most of the
merge data as well.
These issues could be fixed directly, and indeed I initially proposed
such a change at [1] in the past. While this works, there was some
confusion during review because of the inconsistencies.
Instead, its time to clean up the situation properly. Remove
branch->merge_name entirely. Instead, allocate branch->merge earlier
within add_merge() instead of within set_merge(). Instead of having
set_merge() copy from merge_name[i] to merge[i]->src, just have
add_merge() directly initialize merge[i]->src.
Modify the add_merge() to call xstrdup() itself, instead of having
the caller of add_merge() do so. This makes it more obvious which code
owns the memory.
Update all callers which use branch->merge_name[i] to use
branch->merge[i]->src instead.
Add a merge_clear() function which properly releases all of the
merge-related memory, and which sets branch->merge_nr to zero. Use this
both in branch_release() and in set_merge(), fixing the leak when
set_merge() finds no valid remote_name.
Add a set_merge variable to the branch structure, which indicates
whether set_merge() has been called. This replaces the previous use of a
NULL check against the branch->merge array.
With these changes, the merge array is always allocated when merge_nr is
non-zero.
This use of refspec_item to store the names should be safe. External
callers should be using branch_get() to obtain a pointer to the branch,
which will call set_merge(), and the callers internal to remote.c
already handle the partially initialized refpsec_item structure safely.
This end result is cleaner, and avoids duplicating the merge names
twice.

In ddee3703b3 (builtin/repack.c: add cruft packs to MIDX during
geometric repack, 2022-05-20), repack began adding cruft pack(s) to the
MIDX with '--write-midx' to ensure that the resulting MIDX was always
closed under reachability in order to generate reachability bitmaps.
While the previous patch added the '--stdin-packs=follow' option to
pack-objects, it is not yet on by default. Given that, suppose you have
a once-unreachable object packed in a cruft pack, which later becomes
reachable from one or more objects in a geometrically repacked pack.
That once-unreachable object *won't* appear in the new pack, since the
cruft pack was not specified as included or excluded when the
geometrically repacked pack was created with 'pack-objects
--stdin-packs' (*not* '--stdin-packs=follow', which is not on). If that
new pack is included in a MIDX without the cruft pack, then trying to
generate bitmaps for that MIDX may fail. This happens when the bitmap
selection process picks one or more commits which reach the
once-unreachable objects.
To mitigate this failure mode, commit ddee3703b3 ensures that the MIDX
will be closed under reachability by including cruft pack(s). If cruft
pack(s) were not included, we would fail to generate a MIDX bitmap. But
ddee3703b3 alludes to the fact that this is sub-optimal by saying
[...] it's desirable to avoid including cruft packs in the MIDX
because it causes the MIDX to store a bunch of objects which are
likely to get thrown away.
, which is true, but hides an even larger problem. If repositories
rarely prune their unreachable objects and/or have many of them, the
MIDX must keep track of a large number of objects which bloats the MIDX
and slows down object lookup.
This is doubly unfortunate because the vast majority of objects in cruft
pack(s) are unlikely to be read. But any object lookups that go through
the MIDX must binary search over them anyway, slowing down object
lookups using the MIDX.
This patch causes geometrically-repacked packs to contain a copy of any
once-unreachable object(s) with 'git pack-objects --stdin-packs=follow',
allowing us to avoid including any cruft packs in the MIDX. This is
because a sequence of geometrically-repacked packs that were all
generated with '--stdin-packs=follow' are guaranteed to have their union
be closed under reachability.
Note that you cannot guarantee that a collection of packs is closed
under reachability if not all of them were generated with "following" as
above. One tell-tale sign that not all geometrically-repacked packs in
the MIDX were generated with "following" is to see if there is a pack in
the existing MIDX that is not going to be somehow represented (either
verbatim or as part of a geometric rollup) in the new MIDX.
If there is, then starting to generate packs with "following" during
geometric repacking won't work, since it's open to the same race as
described above.
But if you're starting from scratch (e.g., building the first MIDX after
an all-into-one '--cruft' repack), then you can guarantee that the union
of subsequently generated packs from geometric repacking *is* closed
under reachability.
(One exception here is when "starting from scratch" results in a noop
repack, e.g., because the non-cruft pack(s) in a repository already form
a geometric progression. Since we can't tell whether or not those were
generated with '--stdin-packs=follow', they may depend on
once-unreachable objects, so we have to include the cruft pack in the
MIDX in this case.)
Detect when this is the case and avoid including cruft packs in the MIDX
where possible. The existing behavior remains the default, and the new
behavior is available with the config 'repack.midxMustIncludeCruft' set
to 'false'.

When invoked with '--stdin-packs', pack-objects will generate a pack
which contains the objects found in the "included" packs, less any
objects from "excluded" packs.
Packs that exist in the repository but weren't specified as either
included or excluded are in practice treated like the latter, at least
in the sense that pack-objects won't include objects from those packs.
This behavior forces us to include any cruft pack(s) in a repository's
multi-pack index for the reasons described in ddee3703b3
(builtin/repack.c: add cruft packs to MIDX during geometric repack,
2022-05-20).
The full details are in ddee3703b3, but the gist is if you
have a once-unreachable object in a cruft pack which later becomes
reachable via one or more commits in a pack generated with
'--stdin-packs', you *have* to include that object in the MIDX via the
copy in the cruft pack, otherwise we cannot generate reachability
bitmaps for any commits which reach that object.
Note that the traversal here is best-effort, similar to the existing
traversal which provides name-hash hints. This means that the object
traversal may hand us back a blob that does not actually exist. We
*won't* see missing trees/commits with 'ignore_missing_links' because:
- missing commit parents are discarded at the commit traversal stage by
revision.c::process_parents()
- missing tag objects are discarded by revision.c::handle_commit()
- missing tree objects are discarded by the list-objects code in
list-objects.c::process_tree()
But we have to handle potentially-missing blobs specially by making a
separate check to ensure they exist in the repository. Failing to do so
would mean that we'd add an object to the packing list which doesn't
actually exist, rendering us unable to write out the pack.
This prepares us for new repacking behavior which will "resurrect"
objects found in cruft or otherwise unspecified packs when generating
new packs. In the context of geometric repacking, this may be used to
maintain a sequence of geometrically-repacked packs, the union of which
is closed under reachability, even in the case described earlier.

With '--unpacked', pack-objects adds loose objects (which don't appear
in any of the excluded packs from '--stdin-packs') to the output pack
without considering them as reachability tips for the name-hash
traversal.
This was an oversight in the original implementation of '--stdin-packs',
since the code which enumerates and adds loose objects to the output
pack (`add_unreachable_loose_objects()`) did not have access to the
'rev_info' struct found in `read_packs_list_from_stdin()`.
Excluding unpacked objects from that traversal doesn't affect the
correctness of the resulting pack, but it does make it harder to
discover good deltas for loose objects.
Now that the 'rev_info' struct is declared outside of
`read_packs_list_from_stdin()`, we can pass it to
`add_objects_in_unpacked_packs()` and add any loose objects as tips to
the above-mentioned traversal, in theory producing slightly tighter
packs as a result.

Once 'read_packs_list_from_stdin()' has called for_each_object_in_pack()
on each of the input packs, we do a reachability traversal to discover
names for any objects we picked up so we can generate name hash values
and hopefully get higher quality deltas as a result.
A future commit will change the purpose of this reachability traversal
to find and pack objects which are reachable from commits in the input
packs, but are packed in an unknown (not included nor excluded) pack.
Extract the code which initializes and performs the reachability
traversal to take place in the caller, not the callee, which prepares us
to share this code for the '--unpacked' case (see the function
add_unreachable_loose_objects() for more details).

While looping over a counter "i", we do:
printf "[submodule \"sm-$i\"]\npath = recursive-submodule-path-$i\n" "$i"
So we are passing "$i" as an argument to be filled in, but there is no
"%" placeholder in the format string, which is a bit confusing to read.
We could switch both instances of "$i" to "%d" (and pass $i twice). But
that makes the line even longer. Let's just keep interpolating the value
in the string, and drop the confusing extra "$i" argument.
And since we are not using any printf specifiers at all, it becomes
clear that we can swap it out for echo. We do use a "\n" in the middle
of the string, but breaking this into two separate echo statements
actually makes it easier to read.

Whenever we sent a message using the `imap-send` command, it would
display a log showing the number of messages which are to be sent.
For example:
sending 1 message
100% (1/1) done
This had been made more informative by adding the name of the destination
folder as well:
Sending 1 message to Drafts folder...
100% (1/1) done

When requesting for passsword, git credential helper used to display
only the host name. For example:
Password for 'imaps://gargaditya08%40live.com@outlook.office365.com':
Now, it will display the port along with the host name:
Password for 'imaps://gargaditya08%40live.com@outlook.office365.com:993':
This has been done to make credential helpers more specific for ports.
Also, this behaviour will also mimic git send-email, which displays
the port along with the host name when requesting for a password.

Various IMAP servers have different ways to name common folders.
For example, the folder where all deleted messages are stored is often
named "[Gmail]/Trash" on Gmail servers, and "Deleted" on Outlook.
Similarly, the Drafts folder is simply named "Drafts" on Outlook, but
on Gmail it is named "[Gmail]/Drafts".
This commit adds a `--list` command to the `imap-send` tool that lists
the available folders on the IMAP server, allowing users to see
which folders are available and how they are named. A sample output
looks like this when run against a Gmail server:
Fetching the list of available folders...
* LIST (\HasNoChildren) "/" "INBOX"
* LIST (\HasChildren \Noselect) "/" "[Gmail]"
* LIST (\All \HasNoChildren) "/" "[Gmail]/All Mail"
* LIST (\Drafts \HasNoChildren) "/" "[Gmail]/Drafts"
* LIST (\HasNoChildren \Important) "/" "[Gmail]/Important"
* LIST (\HasNoChildren \Sent) "/" "[Gmail]/Sent Mail"
* LIST (\HasNoChildren \Junk) "/" "[Gmail]/Spam"
* LIST (\Flagged \HasNoChildren) "/" "[Gmail]/Starred"
* LIST (\HasNoChildren \Trash) "/" "[Gmail]/Trash"
For OpenSSL, this is achived by running the 'IMAP LIST' command and
parsing the response. This command is specified in RFC6154:
https://datatracker.ietf.org/doc/html/rfc6154#section-5.1
For libcurl, the example code published in the libcurl documentation
is used to implement this functionality:

The current implementation for PLAIN in imap-send works just fine
if using curl, but if attempted to use for OpenSSL, it is treated
as an invalid mechanism. The default implementation for OpenSSL is
IMAP LOGIN command rather than AUTH PLAIN. Since AUTH PLAIN is
still used today by many email providers in form of app passwords,
lets add an implementation that can use AUTH PLAIN if specified.

OAuth2.0 is a new way of authentication supported by various email providers
these days. OAUTHBEARER and XOAUTH2 are the two most common mechanisms used

XOAUTH2 is Google's proprietary mechanism (See [3]).

OpenSSL
Unlike PLAIN, XOAUTH2 and OAUTHBEARER, CRAM-MD5 authentication is not
supported by libcurl and requires OpenSSL. If the user tries to use
CRAM-MD5 authentication without OpenSSL, the previous behaviour was to
attempt to authenticate and fail with a die(error). Handle this in a
better way by first checking if OpenSSL is available and then attempting
to authenticate. If OpenSSL is not available, print an error message and
exit gracefully.

Existing `merge.stat` configuration variable is a Boolean that

Extend it to be "Boolean or text", that takes false, true, or

"git merge" and "git pull" shows "git diff --stat --summary @{1}"
when they finish to indicate the extent of the changes brought into

annoying when there are very many created or deleted paths.
Introduce "--compact-summary" option to these two commands that
tells it to instead show "git diff --compact-summary @{1}", which

The git cat-file command with --mailmap option fails to apply mailmap
transformations to the committer field when the author and committer
identities are different. This occurs due to a missing newline handling
in apply_mailmap_to_header() after processing each identity line.
When rewrite_ident_line() processes an identity, it stops at the end
of the identity data (e.g., "Author Name <email> timestamp"), but
doesn't account for the trailing newline. The current code adds the
identity length to buf_offset but fails to advance past the newline
character. This causes the next iteration to start parsing from the
newline instead of the beginning of the next header line, making it
impossible to match subsequent headers like "committer".
Additionally, rewrite_ident_line() may reallocate the buffer during
its operation. Any code using pointers into the old buffer would be
using invalid memory after such a reallocation.
This bug was introduced in e9c1b0e3 (revision: improve
commit_rewrite_person(), 2022-07-19) when the much simpler version of
commit_rewrite_person() that worked on one "person header" at a time
was rewritten to use the current apply_mailmap_to_header() function.
The original implementation processed author and committer separately,
but the rewrite introduced this loop-based approach that failed to
properly handle the transition between identity lines.
Let's fix this by addressing both issues:
1. After processing an identity line, we now check if we're at a
newline and advance past it, ensuring the next header line is
parsed correctly.
2. We recompute the buffer position after rewrite_ident_line() to
handle potential buffer reallocation.
This ensures that all identity headers in commit and tag objects are
consistently processed regardless of whether the author and committer
are the same person.

Now that we have a way to export stashes to a ref, let's provide a way
to import them from such a ref back to the stash. This works much the
way the export code does, except that we strip off the first parent
chain commit and then store each resulting commit back to the stash.
We don't clear the stash first and instead add the specified stashes to
the top of the stash. This is because users may want to export just a
few stashes, such as to share a small amount of work in progress with a
colleague, and it would be undesirable for the receiving user to lose
all of their data. For users who do want to replace the stash, it's
easy to do to: simply run "git stash clear" first.
We specifically rely on the fact that we'll produce identical stash
commits on both sides in our tests. This provides a cheap,
straightforward check for our tests and also makes it easy for users to
see if they already have the same data in both repositories.

A common user problem is how to sync in-progress work to another
machine. Users currently must use some sort of transfer of the working
tree, which poses security risks and also necessarily causes the index
to become dirty. The experience is suboptimal and frustrating for
users.
A reasonable idea is to use the stash for this purpose, but the stash is
stored in the reflog, not in a ref, and as such it cannot be pushed or
pulled. This also means that it cannot be saved into a bundle or
preserved elsewhere, which is a problem when using throwaway development
environments.
In addition, users often want to replicate stashes across machines, such
as when they must use multiple machines or when they use throwaway dev
environments, such as those based on the Devcontainer spec, where they
might otherwise lose various in-progress work.
Let's solve this problem by allowing the user to export the stash to a
ref (or, to just write it into the repository and print the hash, à la
git commit-tree). Introduce git stash export, which writes a chain of
commits where the first parent is always a chain to the previous stash,
or to a single, empty commit (for the final item) and the second is the
stash commit normally written to the reflog.
Iterate over each stash from top to bottom, looking up the data for each
one, and then create the chain from the single empty commit back up in
reverse order. Generate a predictable empty commit so our behavior is
reproducible. Create a useful commit message, preserving the author and
committer information, to help users identify stash commits when viewing
them as normal commits.
If the user has specified specific stashes they'd like to export
instead, use those instead of iterating over all of the stashes.
As part of this, specifically request quiet behavior when looking up the
OID for a revision because we will eventually hit a revision that
doesn't exist and we don't want to die when that occurs.
When exporting stashes, be sure to verify that they look like valid
stashes and don't contain invalid data. This will help avoid failures
on import or problems due to attempting to export invalid refs that are
not stashes.

A reasonable person looking at the signature and usage of get_oid and
friends might conclude that in the event of an error, it always returns
-1. However, this is not the case. Instead, get_oid_basic dies if we
go too far back into the history of a reflog (or, when quiet, simply
exits).
This is not especially useful, since in many cases, we might want to
handle this error differently. Let's add a flag here to make it just
return -1 like elsewhere in these code paths.
Note that we cannot make this behavior the default, since we have many
other codepaths that rely on the existing behavior, including in tests.

It is quite helpful to know what Coverity said, exactly, in case it
fails to analyze the code.

When I added the Coverity workflow in a56b6230d0b1 (ci: add a GitHub
workflow to submit Coverity scans, 2023-09-25), I merely converted an
Azure Pipeline definition that had been running successfully for ages.
In the meantime, the current Coverity documentation describes a very
different way to install the analysis tool, recommending to add the
`bin/` directory to the _end_ of `PATH` (when originally, IIRC, it was
recommended to add it to the _beginning_ of the `PATH`).
This is crucial! The reason is that the current incarnation of the
Windows variant of Coverity's analysis tools come with a _lot_ of DLL
files in their `bin/` directory, some of them interferring rather badly
with the `gcc.exe` in Git for Windows' SDK that we use to run the
Coverity build. The symptom is a cryptic error message:
make: *** [Makefile:2960: headless-git.o] Error 1
make: *** Waiting for unfinished jobs....
D:\git-sdk-64-minimal\mingw64\bin\windres.exe: preprocessing failed.
make: *** [Makefile:2679: git.res] Error 1
make: *** [Makefile:2893: git.o] Error 1
make: *** [Makefile:2893: builtin/add.o] Error 1

****************************************************
Warning: Build command make.exe exited with code 2. Please verify that the build completed successfully.
Warning: Emitted 0 C/C++ compilation units (0%) successfully
0 C/C++ compilation units (0%) are ready for analysis
For more details, please look at:
D:/a/git/git/cov-int/build-log.txt
The log (which the workflow is currently not configured to reveal) then
points out that the `windows.h` header cannot be found, which is _still_
not very helpful. The underlying root cause is that the `gcc.exe` in Git
for Windows' SDK determines the location of the header files via the
location of certain DLL files, and finding the "wrong" ones first on the
`PATH` misleads that logic.
Let's fix this problem by following Coverity's current recommendation
and append the `bin/` directory in which `cov-int` can be found to the
_end_ of `PATH`.

When creating a stash, Git uses the current branch name
of the superproject to construct the stash commit message.
However, in repositories with submodules,
the message may mistakenly display the submodule branch name instead.
This is because `refs_resolve_ref_unsafe()` returns a pointer to a static buffer.
Subsequent calls to the same function overwrite the buffer,
corrupting the originally fetched `branch_name` used for the stash message.
Use `xstrdup()` to duplicate the branch name immediately after resolving it,
so that later buffer overwrites do not affect the stash message.

Refactor "preload-index.c" to remove the dependency on the global
'the_repository'. Replace the occurrences of 'the_repository' with
'index->repo' and thus remove the definition '#define
USE_THE_REPOSITORY_VARIABLE'.
