Doc updates to clarify what an "unborn branch" means.
* jc/orphan-unborn:
orphan/unborn: fix use of 'orphan' in end-user facing messages
orphan/unborn: add to the glossary and use them consistently
|
|
Use a single translatable string to report that the worktree add option
--orphan is incompatible with a commit-ish instead of having the
commit-ish in a separate translatable string. This reduces the number
of strings to translate and gives translators the full context.
A similar message is used in builtin/describe.c, but with the plural of
commit-ish, and here we need the singular form.

"orphan branch" is not even grammatical ("orphaned branch" is), and
we have been using "unborn branch" to mean the state where the HEAD
points at a branch that does not yet exist.
Update end-user facing messages to correct them. There are cases
other random words are used (e.g., "unparented branch") but now we
have a glossary entry, use the term "unborn branch" consistently.

Add a new "const struct config_context *ctx" arg to config_fn_t to hold
additional information about the config iteration operation.
config_context has a "struct key_value_info kvi" member that holds
metadata about the config source being read (e.g. what kind of config
source it is, the filename, etc). In this series, we're only interested
in .kvi, so we could have just used "struct key_value_info" as an arg,
but config_context makes it possible to add/adjust members in the future
without changing the config_fn_t signature. We could also consider other
ways of organizing the args (e.g. moving the config name and value into
config_context or key_value_info), but in my experiments, the
incremental benefit doesn't justify the added complexity (e.g. a
config_fn_t will sometimes invoke another config_fn_t but with a
different config value).
In subsequent commits, the .kvi member will replace the global "struct
config_reader" in config.c, making config iteration a global-free
operation. It requires much more work for the machinery to provide
meaningful values of .kvi, so for now, merely change the signature and
call sites, pass NULL as a placeholder value, and don't rely on the arg
in any meaningful way.
Most of the changes are performed by
contrib/coccinelle/config_fn_ctx.pending.cocci, which, for every
config_fn_t:
- Modifies the signature to accept "const struct config_context *ctx"
- Passes "ctx" to any inner config_fn_t, if needed
- Adds UNUSED attributes to "ctx", if needed
Most config_fn_t instances are easily identified by seeing if they are
called by the various config functions. Most of the remaining ones are
manually named in the .cocci patch. Manual cleanups are still needed,
but the majority of it is trivial; it's either adjusting config_fn_t
that the .cocci patch didn't catch, or adding forward declarations of
"struct config_context ctx" to make the signatures make sense.
The non-trivial changes are in cases where we are invoking a config_fn_t
outside of config machinery, and we now need to decide what value of
"ctx" to pass. These cases are:
- trace2/tr2_cfg.c:tr2_cfg_set_fl()
This is indirectly called by git_config_set() so that the trace2
machinery can notice the new config values and update its settings
using the tr2 config parsing function, i.e. tr2_cfg_cb().
- builtin/checkout.c:checkout_main()
This calls git_xmerge_config() as a shorthand for parsing a CLI arg.
This might be worth refactoring away in the future, since
git_xmerge_config() can call git_default_config(), which can do much
more than just parsing.
Handle them by creating a KVI_INIT macro that initializes "struct
key_value_info" to a reasonable default, and use that to construct the
"ctx" arg.

Since this header showed up in some places besides just #include
statements, update/clean-up/remove those other places as well.
Note that compat/fsmonitor/fsm-path-utils-darwin.c previously got
away with violating the rule that all files must start with an include
of git-compat-util.h (or a short-list of alternate headers that happen
to include it first). This change exposed the violation and caused it
to stop building correctly; fix it by having it include
git-compat-util.h first, as per policy.

functions from cache.h to read-cache.h. The purpose of the

The index is read in 'worktree.c' at two points:
1.The 'validate_no_submodules' function, which checks if there are any
submodules present in the worktree.
2.The 'check_clean_worktree' function, which verifies if a worktree is
'clean', i.e., there are no untracked or modified but uncommitted files.
This is done by running the 'git status' command, and an error message
is thrown if the worktree is not clean. Given that 'git status' is
already sparse-aware, the function is also sparse-aware.
Hence we can just set the requires-full-index to false for
"git worktree".
Add tests that verify that 'git worktree' behaves correctly when the
sparse index is enabled and test to ensure the index is not expanded.
The `p2000` tests demonstrate a ~20% execution time reduction for
'git worktree' using a sparse index:
(Note:the p2000 test results didn't reflect the huge speedup because of
the index reading time is minuscule comparing to the filesystem
operations.)

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 ebaf3bcf1ae (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.

Extend DWIM to try to infer `--orphan` when in an empty repository. i.e.
a repository with an invalid/unborn HEAD, no local branches, and if
`--guess-remote` is used then no remote branches.
This behavior is equivalent to `git switch -c` or `git checkout -b` in
an empty repository.
Also warn the user (overriden with `-f`/`--force`) when they likely
intend to checkout a remote branch to the worktree but have not yet
fetched from the remote. i.e. when using `--guess-remote` and there is a
remote but no local or remote refs.

hash.h depends upon and includes repository.h, due to the definition and
use of the_hash_algo (defined as the_repository->hash_algo). However,
most headers trying to include hash.h are only interested in the layout
of the structs like object_id. Move the parts of hash.h that do not
depend upon repository.h into a new file hash-ll.h (the "low level"
parts of hash.h), and adjust other files to use this new header where
the convenience inline functions aren't needed.
This allows hash.h and object.h to be fairly small, minimal headers. It
also exposes a lot of hidden dependencies on both path.h (which was
brought in by repository.h) and repository.h (which was previously
implicitly brought in by object.h), so also adjust other files to be
more explicit about what they depend upon.

We already have the basic "git_config_get_value()" function and its
"repo_*" and "configset" siblings to get a given "key" and assign the
last key found to a provided "value".
But some callers don't care about that value, but just want to use the
return value of the "get_value()" function to check whether the key
exist (or another non-zero return value).
The immediate motivation for this is that a subsequent commit will
need to change all callers of the "*_get_value_multi()" family of
functions. In two cases here we (ab)used it to check whether we had
any values for the given key, but didn't care about the return value.
The rest of the callers here used various other config API functions
to do the same, all of which resolved to the same underlying functions
to provide the answer.
Some of these were using either git_config_get_string() or
git_config_get_string_tmp(), see fe4c750fb13 (submodule--helper: fix a
configure_added_submodule() leak, 2022-09-01) for a recent example. We
can now use a helper function that doesn't require a throwaway
variable.
We could have changed git_configset_get_value_multi() (and then
git_config_get_value() etc.) to accept a "NULL" as a "dest" for all
callers, but let's avoid changing the behavior of existing API
users. Having an "unused" value that we throw away internal to
config.c is cheap.
A "NULL as optional dest" pattern is also more fragile, as the intent
of the caller might be misinterpreted if he were to accidentally pass
"NULL", e.g. when "dest" is passed in from another function.
Another name for this function could have been
"*_config_key_exists()", as suggested in [1]. That would work for all
of these callers, and would currently be equivalent to this function,
as the git_configset_get_value() API normalizes all non-zero return
values to a "1".
But adding that API would set us up to lose information, as e.g. if
git_config_parse_key() in the underlying configset_find_element()
fails we'd like to return -1, not 1.
Let's change the underlying configset_find_element() function to
support this use-case, we'll make further use of it in a subsequent
commit where the git_configset_get_value_multi() function itself will
expose this new return value.
This still leaves various inconsistencies and clobbering or ignoring
of the return value in place. E.g here we're modifying
configset_add_value(), but ever since it was added in [2] we've been
ignoring its "int" return value, but as we're changing the
configset_find_element() it uses, let's have it faithfully ferry that
"ret" along.
Let's also use the "RESULT_MUST_BE_USED" macro introduced in [3] to
assert that we're checking the return value of
configset_find_element().
We're leaving the same change to configset_add_value() for some future
series. Once we start paying attention to its return value we'd need
to ferry it up as deep as do_config_from(), and would need to make
least read_{,very_}early_config() and git_protected_config() return an
"int" instead of "void". Let's leave that for now, and focus on
the *_get_*() functions.

Dozens of files made use of gettext functions, without explicitly
including gettext.h. This made it more difficult to find which files
could remove a dependence on cache.h. Make C files explicitly include
gettext.h if they are using it.
However, while compat/fsmonitor/fsm-ipc-darwin.c should also gain an
include of gettext.h, it was left out to avoid conflicting with an
in-flight topic.

We were leaking both the "struct strbuf" in prune_worktrees(), as well
as the "path" we got from should_prune_worktree(). Since these were
the only two uses of the "struct string_list" let's change it to a
"DUP" and push these to it with "string_list_append_nodup()".
For the string_list_append_nodup() we could also string_list_append()
the main_path.buf, and then strbuf_release(&main_path) right away. But
doing it this way avoids an allocation, as we already have the "struct
strbuf" prepared for appending to "kept".

When the "repo" member was added to "the_index" in [1] the
repo_read_index() was made to populate it, but the unpopulated
"the_index" variable didn't get the same treatment.
Let's do that in initialize_the_repository() when we set it up, and
likewise for all of the current callers initialized an empty "struct
index_state".
This simplifies code that needs to deal with "the_index" or a custom
"struct index_state", we no longer need to second-guess this part of
the "index_state" deep in the stack. A recent example of such
second-guessing is the "istate->repo ? istate->repo : the_repository"
code in [2]. We can now simply use "istate->repo".
We're doing this by making use of the INDEX_STATE_INIT() macro (and
corresponding function) added in [3], which now have mandatory "repo"
arguments.
Because we now call index_state_init() in repository.c's
initialize_the_repository() we don't need to handle the case where we
have a "repo->index" whose "repo" member doesn't match the "repo"
we're setting up, i.e. the "Complete the double-reference" code in
repo_read_index() being altered here. That logic was originally added
in [1], and was working around the lack of what we now have in
initialize_the_repository().
For "fsmonitor-settings.c" we can remove the initialization of a NULL
"r" argument to "the_repository". This was added back in [4], and was
needed at the time for callers that would pass us the "r" from an
"istate->repo". Before this change such a change to
"fsmonitor-settings.c" would segfault all over the test suite (e.g. in
t0002-gitfile.sh).
This change has wider eventual implications for
"fsmonitor-settings.c". The reason the other lazy loading behavior in
it is required (starting with "if (!r->settings.fsmonitor) ..." is
because of the previously passed "r" being "NULL".
I have other local changes on top of this which move its configuration
reading to "prepare_repo_settings()" in "repo-settings.c", as we could
now start to rely on it being called for our "r". But let's leave all
of that for now, and narrowly remove this particular part of the
lazy-loading.

Hopefully in some not so distant future, we'll get advantages from always
initializing the "repo" member of the "struct index_state". To make
that easier let's introduce an initialization macro & function.
The various ad-hoc initialization of the structure can then be changed
over to it, and we can remove the various "0" assignments in
discard_index() in favor of calling index_state_init() at the end.
While not strictly necessary, let's also change the CALLOC_ARRAY() of
various "struct index_state *" to use an ALLOC_ARRAY() followed by
index_state_init() instead.
We're then adding the release_index() function and converting some
callers (including some of these allocations) over to it if they
either won't need to use their "struct index_state" again, or are just
about to call index_state_init().

For a lot of uses of UNLEAK() it would be quite tricky to release the
memory involved, or we're missing the relevant *_(release|clear)()
functions. But in these cases we have them already, and can just
invoke them on the variable(s) involved, instead of UNLEAK().
For "builtin/worktree.c" the UNLEAK() was also added in [1], but the
struct member it's unleaking was removed in [2]. The only non-"int"
member of that structure is "const char *keep_locked", which comes to
us via "argv" or a string literal[3].
We have good visibility via the compiler and
tooling (e.g. SANITIZE=address) on bad free()-ing, but none on
UNLEAK() we don't need anymore. So let's prefer releasing the memory
when it's easy.
For "bugreport", "worktree" and "config" we need to start using a "ret
= ..." return pattern. For "builtin/bugreport.c" these UNLEAK() were
added in [4], and for "builtin/config.c" in [1].
For "config" the code seen here was the only user of the "value"
variable. For "ACTION_{RENAME,REMOVE}_SECTION" we need to be sure to
return the right exit code in the cases where we were relying on
falling through to the top-level.
I think there's still a use-case for UNLEAK(), but hat it's changed
since then. Using it so that "we can see the real leaks" is
counter-productive in these cases.
It's more useful to have UNLEAK() be a marker of the remaining odd
cases where it's hard to free() the memory for whatever reason. With
this change less than 20 of them remain in-tree.

Avoid repeating the "-h" output for the "git worktree" command, and
