Remove `git_common_path()` in favor of the `repo_common_path()` family
of functions, which makes the implicit dependency on `the_repository` go
away.
Note that `git_common_path()` used to return a string allocated via
`get_pathname()`, which uses a rotating set of statically allocated
buffers. Consequently, callers didn't have to free the returned string.
The same isn't true for `repo_common_path()`, so we also have to add
logic to free the returned strings.
This refactoring also allows us to remove `repo_common_pathv()` from the
public interface.

The `get_worktree_git_dir()` function returns a string constant that
does not need to be free'd by the caller. This string is computed for
three different cases:
- If we don't have a worktree we return a path into the Git directory.
The returned string is owned by `the_repository`, so there is no
need for the caller to free it.
- If we have a worktree, but no worktree ID then the caller requests
the main worktree. In this case we return a path into the common
directory, which again is owned by `the_repository` and thus does
not need to be free'd.
- In the third case, where we have an actual worktree, we compute the
path relative to "$GIT_COMMON_DIR/worktrees/". This string does not
need to be released either, even though `git_common_path()` ends up
allocating memory. But this doesn't result in a memory leak either
because we write into a buffer returned by `get_pathname()`, which
returns one out of four static buffers.
We're about to drop `git_common_path()` in favor of `repo_common_path()`,
which doesn't use the same mechanism but instead returns an allocated
string owned by the caller. While we could adapt `get_worktree_git_dir()`
to also use `get_pathname()` and print the derived common path into that
buffer, the whole schema feels a lot like premature optimization in this
context. There are some callsites where we call `get_worktree_git_dir()`
in a loop that iterates through all worktrees. But none of these loops
seem to be even remotely in the hot path, so saving a single allocation
there does not feel worth it.
Refactor the function to instead consistently return an allocated path
so that we can start using `repo_common_path()` in a subsequent commit.

As explained in an earlier commit, we're refactoring path-related
functions to provide a consistent interface for computing paths into the
commondir, gitdir and worktree. Refactor the "submodule" family of
functions accordingly.
Note that in contrast to the other `repo_*_path()` families, we have to
pass in the repository as a non-constant pointer. This is because we end
up calling `repo_read_gitmodules()` deep down in the callstack, which
may end up modifying the repository.

The functions provided by the "path" subsystem to derive repository
paths for the commondir, gitdir, worktrees and submodules are quite
inconsistent. Some functions have a `strbuf_` prefix, others have
different return values, some don't provide a variant working on top of
`strbuf`s.
We're thus about to refactor all of these family of functions so that
they follow a common pattern:
- `repo_*_path()` returns an allocated string.
- `repo_*_path_append()` appends the path to the caller-provided
buffer while returning a constant pointer to the buffer. This
clarifies whether the buffer is being appended to or rewritten,
which otherwise wasn't immediately obvious.
- `repo_*_path_replace()` replaces contents of the buffer with the
computed path, again returning a pointer to the buffer contents.
The returned constant pointer isn't being used anywhere yet, but it will
be used in subsequent commits. Its intent is to allow calling patterns
like the following somewhat contrived example:
if (!stat(&st, repo_common_path_replace(repo, &buf, ...)) &&
!unlink(repo_common_path_replace(repo, &buf, ...)))
...
Refactor the commondir family of functions accordingly and adapt all
callers.
Note that `repo_common_pathv()` is converted into an internal
implementation detail. It is only used to implement `the_repository`
compatibility shims and will eventually be removed from the public
interface.

When extensions.worktreeConfig is true and the main worktree is
bare -- that is, its config.worktree file contains core.bare=true
-- commands run from secondary worktrees incorrectly see the main
worktree as not bare. As such, those commands incorrectly think
that the repository's default branch (typically "main" or
"master") is checked out in the bare repository even though it's
not. This makes it impossible, for instance, to checkout or delete
the default branch from a secondary worktree, among other
shortcomings.
This problem occurs because, when extensions.worktreeConfig is
true, commands run in secondary worktrees only consult
$commondir/config and $commondir/worktrees/<id>/config.worktree,
thus they never see the main worktree's core.bare=true setting in
$commondir/config.worktree.
Fix this problem by consulting the main worktree's config.worktree
file when checking whether it is bare. (This extra work is
performed only when running from a secondary worktree.)

This refactors `repair_worktree_after_gitdir_move()` to use the new
`write_worktree_linking_files` function. It also preserves the
relativity of the linking files; e.g., if an existing worktree used
absolute paths then the repaired paths will be absolute (and visa-versa).
`repair_worktree_after_gitdir_move()` is used to repair both sets of
worktree linking files if the `.git` directory is moved during a
re-initialization using `git init`.
This also adds a test case for reinitializing a repository that has
relative worktrees.

This teaches the `worktree repair` command to respect the
`--[no-]relative-paths` CLI option and `worktree.useRelativePaths`
config setting. If an existing worktree with an absolute path is repaired
with `--relative-paths`, the links will be replaced with relative paths,
even if the original path was correct. This allows a user to covert
existing worktrees between absolute/relative as desired.
To simplify things, both linking files are written when one of the files
needs to be repaired. In some cases, this fixes the other file before it
is checked, in other cases this results in a correct file being written
with the same contents.

Git currently stores absolute paths to both the main repository and
linked worktrees. However, this causes problems when moving repositories
or working in containerized environments where absolute paths differ
between systems. The worktree links break, and users are required to
manually execute `worktree repair` to repair them, leading to workflow
disruptions. Additionally, mapping repositories inside of containerized
environments renders the repository unusable inside the containers, and
this is not repairable as repairing the worktrees inside the containers
will result in them being broken outside the containers.
To address this, this patch makes Git always write relative paths when
linking worktrees. Relative paths increase the resilience of the
worktree links across various systems and environments, particularly
when the worktrees are self-contained inside the main repository (such
as when using a bare repository with worktrees). This improves
portability, workflow efficiency, and reduces overall breakages.
Although Git now writes relative paths, existing repositories with
absolute paths are still supported. There are no breaking changes
to workflows based on absolute paths, ensuring backward compatibility.
At a low level, the changes involve modifying functions in `worktree.c`
and `builtin/worktree.c` to use `relative_path()` when writing the
worktree’s `.git` file and the main repository’s `gitdir` reference.
Instead of hardcoding absolute paths, Git now computes the relative path
between the worktree and the repository, ensuring that these links are
portable. Locations where these respective file are read have also been
updated to properly handle both absolute and relative paths. Generally,
relative paths are always resolved into absolute paths before any
operations or comparisons are performed.
Additionally, `repair_worktrees_after_gitdir_move()` has been introduced
to address the case where both the `<worktree>/.git` and
`<repo>/worktrees/<id>/gitdir` links are broken after the gitdir is
moved (such as during a re-initialization). This function repairs both
sides of the worktree link using the old gitdir path to reestablish the
correct paths after a move.
The `worktree.path` struct member has also been updated to always store
the absolute path of a worktree. This ensures that worktree consumers
never have to worry about trying to resolve the absolute path themselves.

This lays the groundwork for the next patch, which needs the backlink
returned from infer_backlink() as a `strbuf`. It seemed inefficient to
convert from `strbuf` to `char*` and back to `strbuf` again.
This refactors infer_backlink() to return an integer result and use a
pre-allocated `strbuf` for the inferred backlink path, replacing the
previous `char*` return type and improving efficiency.

* es/worktree-repair-copied:
worktree: repair copied repository and linked worktrees
|
|
For each linked worktree, Git maintains two pointers: (1)
<repo>/worktrees/<id>/gitdir which points at the linked worktree, and
(2) <worktree>/.git which points back at <repo>/worktrees/<id>. Both
pointers are absolute pathnames.
Aside from manually manipulating those raw files, it is possible to
easily "break" one or both pointers by ignoring the "git worktree move"
command and instead manually moving a linked worktree, moving the
repository, or moving both. The "git worktree repair" command was
invented to handle this case by restoring these pointers to sane values.
For the "repair" command, the "git worktree" manual page states:
Repair worktree administrative files, if possible, if they have
become corrupted or outdated due to external factors.
The "if possible" clause was chosen deliberately to convey that the
existing implementation may not be able to fix every possible breakage,
and to imply that improvements may be made to handle other types of
breakage.
A recent problem report[*] illustrates a case in which "git worktree
repair" not only fails to fix breakage, but actually causes breakage.
Specifically, if a repository / main-worktree and linked worktrees are
*copied* as a unit (rather than *moved*), then "git worktree repair" run
in the copy leaves the copy untouched but botches the pointers in the
original repository and the original worktrees.
For instance, given this directory structure:
orig/
main/ (main-worktree)
linked/ (linked worktree)
if "orig" is copied (not moved) to "dup", then immediately after the
manual copy operation:
* orig/main/.git/worktrees/linked/gitdir points at orig/linked/.git
* orig/linked/.git points at orig/main/.git/worktrees/linked
* dup/main/.git/worktrees/linked/gitdir points at orig/linked/.git
* dup/linked/.git points at orig/main/.git/worktrees/linked
So, dup/main thinks its linked worktree is orig/linked, and worktree
dup/linked thinks its repository / main-worktree is orig/main.
"git worktree repair" is reasonably simple-minded; it wants to trust
valid-looking pointers, hence doesn't try to second-guess them. In this
case, when validating dup/linked/.git, it finds a legitimate repository
pointer, orig/main/.git/worktrees/linked, thus trusts that is correct,
but does notice that gitdir in that directory doesn't point at
dup/linked/.git, so it (incorrectly) _fixes_
orig/main/.git/worktrees/linked/gitdir to point at dup/linked/.git.
Similarly, when validating dup/main/.git/worktrees/linked/gitdir, it
finds a legitimate worktree pointer, orig/linked/.git, but notices that
its .git file doesn't point back at dup/main, thus (incorrectly) _fixes_
orig/linked/.git to point at dup/main/.git/worktrees/linked. Hence, it
has modified and broken the linkage between orig/main and orig/linked
rather than fixing dup/main and dup/linked as expected.
Fix this problem by also checking if a plausible .git/worktrees/<id>
exists in the *current* repository -- not just in the repository pointed
at by the worktree's .git file -- and comparing whether they are the
same. If not, then it is likely because the repository / main-worktree
and linked worktrees were copied, so prefer the discovered plausible
pointer rather than the one from the existing .git file.

Use of the `the_repository` variable is deprecated nowadays, and we
slowly but steadily convert the codebase to not use it anymore. Instead,
callers should be passing down the repository to work on via parameters.
It is hard though to prove that a given code unit does not use this
variable anymore. The most trivial case, merely demonstrating that there
is no direct use of `the_repository`, is already a bit of a pain during
code reviews as the reviewer needs to manually verify claims made by the
patch author. The bigger problem though is that we have many interfaces
that implicitly rely on `the_repository`.
Introduce a new `USE_THE_REPOSITORY_VARIABLE` macro that allows code
units to opt into usage of `the_repository`. The intent of this macro is
to demonstrate that a certain code unit does not use this variable
anymore, and to keep it from new dependencies on it in future changes,
be it explicit or implicit
For now, the macro only guards `the_repository` itself as well as
`the_hash_algo`. There are many more known interfaces where we have an
implicit dependency on `the_repository`, but those are not guarded at
the current point in time. Over time though, we should start to add
guards as required (or even better, just remove them).
Define the macro as required in our code units. As expected, most of our
code still relies on the global variable. Nearly all of our builtins
rely on the variable as there is no way yet to pass `the_repository` to
their entry point. For now, declare the macro in "biultin.h" to keep the
required changes at least a little bit more contained.

In `get_worktree_ref_store()` we either return the repository's main ref
store, or we look up the ref store via the map of worktree ref stores.
Which of these worktrees gets picked depends on the `is_current` bit of
the worktree, which indicates whether the worktree is the one that
corresponds to `the_repository`.
The bit is getting set in `get_worktrees()`, but only after we have
computed the list of all worktrees. This is too late though, because at
that time we have already called `get_worktree_ref_store()` on each of
the worktrees via `add_head_info()`. The consequence is that the current
worktree will not have been marked accordingly, which means that we did
not use the main ref store, but instead created a new ref store. We thus
have two separate ref stores now that map to the same ref database.
Fix this by setting `is_current` before we call `add_head_info()`.

Similar as with the preceding commit, the worktree ref stores are always

Refactor the code so that worktrees have a pointer to their repository.
Like this, we can move the global map into `struct repository` and stop
using `the_repository`. With this change, we can now in theory look up
worktree ref stores for repositories other than `the_repository`. In
practice, the worktree code will need further changes to look up
arbitrary worktrees.

Introduce the ability to append comments to modifications

git config --comment "changed via script" \
--add safe.directory /home/alice/repo.git
based on the proposed patch, the output produced is:
[safe]
directory = /home/alice/repo.git #changed via script
Users need to be able to distinguish between config entries made
using automation and entries made by a human. Automation can add
comments containing a URL pointing to explanations for the change
made, avoiding questions from users as to why their config file
was changed by a third party.
The implementation ensures that a # character is unconditionally
prepended to the provided comment string, and that the comment
text is appended as a suffix to the changed key-value-pair in the
same line of text. Multi-line comments (i.e. comments containing
linefeed) are rejected as errors, causing Git to exit without
making changes.
Comments are aimed at humans who inspect or change their Git
config using a pager or editor. Comments are not meant to be

When calling `git init --separate-git-dir=<new-path>` on a preexisting
repository, we move the Git directory of that repository to the new path
specified by the user. If there are worktrees present in the repository,
we need to repair the worktrees so that their gitlinks point to the new
location of the repository.
This repair logic will load repositories via `get_worktrees()`, which
will enumerate up and initialize all worktrees. Part of initialization
is logic that we resolve their respective worktree HEADs, even though
that information may not actually be needed in the end by all callers.
Although not a problem presently with the file-based reference backend,
it will become a problem with the upcoming reftable backend. In the
context of git-init(1) we do not have a fully-initialized repository set
up via `setup_git_directory()` or friends. Consequently, we do not know
about the repository format when `repair_worktrees()` is called, and
properly setting up all parts of the repositroy in `init_db()` before we
try to repair worktrees is not an easy task. With the introduction of
the reftable backend, we would ultimately try to look up the worktree
HEADs before we have figured out the reference format, which does not
work.
We do not require the worktree HEADs at all to repair worktrees. So
let's fix this issue by skipping over the step that reads them.

In 83c750acde (wt-status.*: better advice for git status added,
2012-06-05), git-status received new informative messages to describe
the ongoing work in a worktree.
These messages were enhanced in 0722c805d6 (status: show the branch name
if possible in in-progress info, 2013-02-03), to show, if possible, the
branch where the operation was initiated.
Since then, we show incorrect information when several operations are in
progress and one of them is bisect:
$ git checkout -b foo
$ GIT_SEQUENCE_EDITOR='echo break >' git rebase -i HEAD~
$ git checkout -b bar
$ git bisect start
$ git status
...
You are currently editing a commit while rebasing branch 'bar' on '...'.
You are currently bisecting, started from branch 'bar'.
...
Note that we erroneously say "while rebasing branch 'bar'" when we
should be referring to "foo".
This must have gone unnoticed for so long because it must be unusual to
start a bisection while another operation is in progress. And even less
usual to involve different branches.
It caught my attention reviewing a leak introduced in 8b87cfd000
(wt-status: move strbuf into read_and_strip_branch(), 2013-03-16).
A simple change to deal with this situation can be to record in struct
wt_status_state, the branch where the bisect starts separately from the
branch related to other operations.
Let's do it and so we'll be able to display correct information and
we'll avoid the leak as well.

Further shuffling of declarations across header files to streamline
file dependencies.
* cw/compat-util-header-cleanup:
git-compat-util: move alloc macros to git-compat-util.h
treewide: remove unnecessary includes for wrapper.h
kwset: move translation table from ctype
sane-ctype.h: create header for sane-ctype macros
git-compat-util: move wrapper.c funcs to its header
git-compat-util: move strbuf.c funcs to its header

Reduce reliance on a global state in the config reading API.
* gc/config-context:
config: pass source to config_parser_event_fn_t
config: add kvi.path, use it to evaluate includes
config.c: remove config_reader from configsets
config: pass kvi to die_bad_number()
trace2: plumb config kvi
config.c: pass ctx with CLI config
config: pass ctx with config files
config.c: pass ctx in configsets
config: add ctx arg to config_fn_t
urlmatch.h: use config_fn_t type
config: inline git_color_default_config

alloc_nr, ALLOC_GROW, and ALLOC_GROW_BY are commonly used macros for
dynamic array allocation. Moving these macros to git-compat-util.h with
the other alloc macros focuses alloc.[ch] to allocation for Git objects
and additionally allows us to remove inclusions to alloc.h from files
that solely used the above macros.

Plumb "struct key_value_info" through all code paths that end in
die_bad_number(), which lets us remove the helper functions that read
analogous values from "struct config_reader". As a result, nothing reads
config_reader.config_kvi any more, so remove that too.
In config.c, this requires changing the signature of
git_configset_get_value() to 'return' "kvi" in an out parameter so that
git_configset_get_<type>() can pass it to git_config_<type>(). Only
numeric types will use "kvi", so for non-numeric types (e.g.
git_configset_get_string()), pass NULL to indicate that the out
parameter isn't needed.
Outside of config.c, config callbacks now need to pass "ctx->kvi" to any
of the git_config_<type>() functions that parse a config string into a
number type. Included is a .cocci patch to make that refactor.
The only exceptional case is builtin/config.c, where git_config_<type>()
is called outside of a config callback (namely, on user-provided input),
so config source information has never been available. In this case,
die_bad_number() defaults to a generic, but perfectly descriptive
message. Let's provide a safe, non-NULL for "kvi" anyway, but make sure
not to change the message.

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.

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.

Ever since a64215b6cd ("object.h: stop depending on cache.h; make
cache.h depend on object.h", 2023-02-24), we have a few headers that
could have replaced their include of cache.h with an include of
object.h. Make that change now.
Some C files had to start including cache.h after this change (or some
smaller header it had brought in), because the C files were depending
on things from cache.h but were only formerly implicitly getting
cache.h through one of these headers being modified in this patch.

A few subcommands have been taught to stop users from working on a
branch that is being used in another worktree linked to the same
repository.
* rj/avoid-switching-to-already-used-branch:
switch: reject if the branch is already checked out elsewhere (test)
rebase: refuse to switch to a branch already checked out elsewhere (test)
branch: fix die_if_checked_out() when ignore_current_worktree
worktree: introduce is_shared_symref()
|
|
In 8d9fdd7 (worktree.c: check whether branch is rebased in another
worktree, 2016-04-22) die_if_checked_out() learned a new option
ignore_current_worktree, to modify the operation from "die() if the
branch is checked out in any worktree" to "die() if the branch is
checked out in any worktree other than the current one".
Unfortunately we implemented it by checking the flag is_current in the
worktree that find_shared_symref() returns.
When the same branch is checked out in several worktrees simultaneously,
find_shared_symref() will return the first matching worktree in the list
composed by get_worktrees(). If one of the worktrees with the checked
out branch is the current worktree, find_shared_symref() may or may not
return it, depending on the order in the list.
Instead of find_shared_symref(), let's do the search using use the
recently introduced API is_shared_symref(), and consider
ignore_current_worktree when necessary.

Add a new function, is_shared_symref(), which contains the heart of
find_shared_symref(). Refactor find_shared_symref() to use the new
function is_shared_symref().
Soon, we will use is_shared_symref() to search for symref beyond
the first worktree that matches.
