Partially revert a sanity check that the rest of the config code
was not ready, to avoid triggering it in a corner case.
* gc/config-partial-submodule-kvi-fix:
config: don't BUG when both kvi and source are set
When iterating through config, we read config source metadata from
global values - either a "struct config_source + enum config_scope"
or a "struct key_value_info", using the current_config* functions. Prior
to the series starting from 0c60285147 (config.c: create config_reader
and the_reader, 2023-03-28), we weren't very picky about which values we
should read in which situation; we did note that both groups of values
generally shouldn't be set together, but if both were set,
current_config* preferentially reads key_value_info. When that series
added more structure, we enforced that either the former (when parsing a
config source) can be set, or the latter (when iterating a config set),
but *never* both at the same time. See 9828453ff0 (config.c: remove
current_config_kvi, 2023-03-28) and 5cdf18e7cd (config.c: remove
current_parsing_scope, 2023-03-28).
That was a good simplifying constraint that helped us reason about the
global state, but it turns out that there is at least one situation
where we need both to be set at the same time: in a blobless partial
clone where .gitmodules is missing. "git fetch" in such a repo will
start a config parse over .gitmodules (setting the config_source), and
Git will attempt to lazy-fetch it from the promisor remote. However,
when we try to read the promisor configuration, we start iterating a
config set (setting the key_value_info), and we BUG() out because that's
not allowed any more.
Teaching config_reader to gracefully handle this is somewhat
complicated, but fortunately, there are proposed changes to the config.c
machinery to get rid of this global state, and make the BUG() obsolete
[1]. We should rely on that as the eventual solution, and avoid doing
yet another refactor in the meantime.
Therefore, fix the bug by removing the BUG() check. We're reverting to
an older, less safe state, but that's generally okay since
key_value_info is always preferentially read, so we'd always read the
correct values when we iterate a config set in the middle of a config
parse (like we are here). The reverse would be wrong, but extremely
unlikely to happen since very few callers parse config without going
through a config set.

The value of config.worktree is per-repository, but has been kept
in a singleton global variable per process. This has been OK as
most Git operations interacted with a single repository at a time,
but not right for operations like recursive "grep" that want to
access multiple repositories from a single process without forking.
The global variable has been eliminated and made into a member in
the per-repository data structure.

The 'read_replace_refs' global specifies whether or not we should
respect the references of the form 'refs/replace/<oid>' to replace which
object we look up when asking for '<oid>'. This global has caused issues
when it is not initialized properly, such as in b6551feadf (merge-tree:
load default git config, 2023-05-10).
To make this more robust, move its config-based initialization out of
git_default_config and into prepare_repo_settings(). This provides a
repository-scoped version of the 'read_replace_refs' global.
The global still has its purpose: it is disabled process-wide by the
GIT_NO_REPLACE_OBJECTS environment variable or by a call to
disable_replace_refs() in some specific Git commands.
Since we already encapsulated the use of the constant inside
replace_refs_enabled(), we can perform the initialization inside that
method, if necessary. This solves the problem of forgetting to check the
config, as we will check it before returning this value.
Due to this encapsulation, the global can move to be static within
replace-object.c.
There is an interesting behavior change possible here: we now have a
repository-scoped understanding of this config value. Thus, if there was
a command that recurses into submodules and might follow replace refs,
then it would now respect the core.useReplaceRefs config value in each
repository.
'git grep --recurse-submodules' is such a command that recurses into
submodules in-process. We can demonstrate the granularity of this config
value via a test in t7814.

Move 'repository_format_worktree_config' out of the global scope and into
the 'repository' struct. This change is similar to how
'repository_format_partial_clone' was moved in ebaf3bcf1a (repository: move
global r_f_p_c to repo struct, 2021-06-17), adding it to the 'repository'
struct and updating 'setup.c' & 'repository.c' functions to assign the value
appropriately.
The primary goal of this change is to be able to load the worktree config of
a submodule depending on whether that submodule - not its superproject - has
'extensions.worktreeConfig' enabled. To ensure 'do_git_config_sequence()'
has access to the newly repo-scoped configuration, add a 'struct repository'
argument to 'do_git_config_sequence()' and pass it the 'repo' value from
'config_with_options()'.
Finally, add/update tests in 't3007-ls-files-recurse-submodules.sh' to
verify 'extensions.worktreeConfig' is read an used independently by
superprojects and submodules.

Add a 'struct repository' argument to 'config_with_options()' and remove the
'repo' field from 'struct git_config_source'.
A 'struct repository' instance was originally added to the config source in
e3e8bf046e (submodule-config: pass repo upon blob config read, 2021-08-16)
to improve how submodule blob config content was accessed. At the time, this
was the only use for a 'repository' instance, so it was naturally added only
where it was needed: to 'struct git_config_source'. However, in upcoming
patches, 'config_with_options()' will need the repository instance to access
extension information (regardless of whether a 'config_source' exists). To
make the 'struct repository' instance more easily accessible, move it into
the function's arguments.
Update all callers of 'config_with_options()' to pass the appropriate 'repo'
value:
* in 'builtin/config.c', use 'the_repository'
* in 'submodule--config.c', use the 'repo' arg in 'config_from_gitmodules()'
* in 'read_[very_]early_config()' & 'read_protected_config()', set 'repo' to
NULL (repository instances aren't available there)
* in 'populate_remote_urls()', use the repo instance that has been added to
the 'struct config_include_data'
* in 'repo_read_config()', use the given 'repo' arg
Finally, note that this patch eliminates the fallback to 'the_repository'
that previously existed for the 'config_source' repo instance if it was
NULL. The fallback is no longer necessary, as the 'repo' is set explicitly
in all cases where it is needed.

Update 'do_git_config_sequence()' to read the worktree config from
'config.worktree' in 'opts->git_dir' rather than the gitdir of
'the_repository'.
The worktree config is loaded from the path returned by
'git_pathdup("config.worktree")', the 'config.worktree' relative to the
gitdir of 'the_repository'. If loading the config for a submodule, this path
is incorrect, since 'the_repository' is the superproject. 'opts->git_dir' is
the gitdir of the submodule being configured, so the config file in that
location should be read instead.
To ensure the use of 'opts->git_dir' is safe, require that 'opts->git_dir'
is set if-and-only-if 'opts->commondir' is set (rather than "only-if" as it
is now). In all current usage of 'config_options', these values are set
together, so the stricter check does not change any behavior.
Finally, add tests to 't3007-ls-files-recurse-submodules.sh' to verify the
corrected config is loaded. Use 'ls-files' to test this because, unlike some
other '--recurse-submodules' commands, 'ls-files' parses the config of the
submodule in the same process as the superproject (via 'show_submodule()' ->
'repo_read_index()' -> 'prepare_repo_settings()'). As a result,
'the_repository' points to the config of the superproject but the
commondir/gitdir in the config sequence will be that of the submodule,
providing the exact scenario needed to verify this patch.
The first test ('--recurse-submodules parses submodule repo config') checks
that the submodule's *repo* config is read when running 'ls-files' on the
superproject; this confirms already-working behavior, serving as a reference
for how worktree config parsing should behave. The second test
('--recurse-submodules parses submodule worktree config') tests the same
scenario as the previous but instead using the *worktree* config,
demonstrating the corrected behavior. The 'test_config' helper is extended
for this case so that it properly applies the '--worktree' option to the
configure/unconfigure operations it performs.
Note that, although the submodule worktree config is now parsed instead of
the superproject's, 'extensions.worktreeConfig' in the superproject still
controls whether or not the worktree config is enabled at all in the
submodule. This will be fixed in a later patch.

As a defense-in-depth measure to guard against any potentially-unknown
buffer overflows in `copy_or_rename_section_in_file()`, refuse to work
with overly-long lines in a gitconfig.

There are a couple of spots within `copy_or_rename_section_in_file()`
that incorrectly use an `int` to track an offset within a string, which
may truncate or wrap around to a negative value.
Historically it was impossible to have a line longer than 1024 bytes
anyway, since we used fgets() with a fixed-size buffer of exactly that
length. But the recent change to use a strbuf permits us to read lines
of arbitrary length, so it's possible for a malicious input to cause us
to overflow past INT_MAX and do an out-of-bounds array read.
Practically speaking, however, this should never happen, since it
requires 2GB section names or values, which are unrealistic in
non-malicious circumstances.

When renaming (or deleting) a section of configuration, Git uses the
function `git_config_copy_or_rename_section_in_file()` to rewrite the
configuration file after applying the rename or deletion to the given
section.
To do this, Git repeatedly calls `fgets()` to read the existing
configuration data into a fixed size buffer.
When the configuration value under `old_name` exceeds the size of the
buffer, we will call `fgets()` an additional time even if there is no
newline in the configuration file, since our read length is capped at
`sizeof(buf)`.
If the first character of the buffer (after zero or more characters
satisfying `isspace()`) is a '[', Git will incorrectly treat it as
beginning a new section when the original section is being removed. In
other words, a configuration value satisfying this criteria can
incorrectly be considered as a new secftion instead of a variable in the
original section.
Avoid this issue by using a variable-width buffer in the form of a
strbuf rather than a fixed-with region on the stack. A couple of small
points worth noting:
- Using a strbuf will cause us to allocate arbitrary sizes to match
the length of each line. In practice, we don't expect any
reasonable configuration files to have lines that long, and a
bandaid will be introduced in a later patch to ensure that this is
the case.
- We are using strbuf_getwholeline() here instead of strbuf_getline()
in order to match `fgets()`'s behavior of leaving the trailing LF
character on the buffer (as well as a trailing NUL).
This could be changed later, but using strbuf_getwholeline() changes
the least about this function's implementation, so it is picked as
the safest path.
- It is temping to want to replace the loop to skip over characters
matching isspace() at the beginning of the buffer with a convenience
function like `strbuf_ltrim()`. But this is the wrong approach for a
couple of reasons:
First, it involves a potentially large and expensive `memmove()`
which we would like to avoid. Second, and more importantly, we also
*do* want to preserve those spaces to avoid changing the output of
other sections.
In all, this patch is a minimal replacement of the fixed-width buffer in
`git_config_copy_or_rename_section_in_file()` to instead use a `struct
strbuf`.

Since earlier commits removed the inclusion of cache.h from mailmap.c
and quote.c, it feels odd to have the extern declarations of
global variables in cache.h rather than the actual header included
by the source file. Move these global variable extern declarations
from cache.h to mailmap.c and quote.c.
