[PATCH v2 0/3] includeIf: add "worktree" condition for matching working tree path

[PATCH v2 0/3] includeIf: add "worktree" condition for matching working tree path

[Chen Linxuan]

The `includeIf` mechanism already supports matching on the `.git`
directory path (`gitdir`) and the currently checked out branch
(`onbranch`).  But in multi-worktree setups the `.git` directory of a
linked worktree points into the main repository's `.git/worktrees/`
area, which makes `gitdir` patterns cumbersome when one wants to
include config based on the working tree's checkout path instead.

Introduce two new condition keywords:

  - `worktree:<pattern>` matches the realpath of the current worktree's
    working directory against a glob pattern.
  - `worktree/i:<pattern>` is the case-insensitive variant.

Supported pattern features: glob wildcards, `**/` and `/**`, `~`
expansion, `./` relative paths, and trailing-`/` prefix matching.
The condition never matches in a bare repository.

[PATCH v2 1/3] config: add "worktree" and "worktree/i" includeIf conditions

[Chen Linxuan]

The `includeIf` mechanism already supports matching on the `.git`
directory path (`gitdir`) and the currently checked out branch
(`onbranch`).  But in multi-worktree setups the `.git` directory of a
linked worktree points into the main repository's `.git/worktrees/`
area, which makes `gitdir` patterns cumbersome when one wants to
include config based on the working tree's checkout path instead.

Introduce two new condition keywords:

  - `worktree:<pattern>` matches the realpath of the current worktree's
    working directory (i.e. `repo_get_work_tree()`) against a glob
    pattern.  This is the path returned by `git rev-parse
    --show-toplevel`.

  - `worktree/i:<pattern>` is the case-insensitive variant.

The implementation follows the same structure as `include_by_gitdir()`:
the worktree path is resolved via `strbuf_realpath()`, the condition
pattern is prepared with `prepare_include_condition_pattern()` (which
handles `~` expansion, `./` relative paths, `**/` prefix insertion and
trailing-`/` expansion), and matching is done with `wildmatch()`.  A
second attempt using `strbuf_add_absolute_path()` is performed to
handle symlinked paths.

The condition never matches in bare repositories (where there is no
worktree) or during early config reading (where no repository is
available).

This probably should be further split into two commits, one that
introduces the "by-path" helper function and reimplements the
"gitdir" and "gitdir/i" support with it (i.e., essentially it
amounts to dropping of "struct config_options *" and using "const
char *path" in place of it, I presume), and another patch that adds
worktree support in terms of the "by-path" helper.  

The documentation updates and additional test should probably be
done as part of the second half of this patch, unless the second half
of this patch to add "worktree" and "worktree/i" is too big to be
reviewed standalone (which I do not think would be the case).

[PATCH v2 2/3] Documentation/config: add includeIf "worktree"

[Chen Linxuan]

Add documentation for the newly introduced `worktree` and `worktree/i`
conditional include keywords.  Describe how they differ from `gitdir`
(matching the working tree checkout path instead of the `.git`
directory path), and list the supported pattern features: glob
wildcards, `**/` and `/**`, `~` expansion, `./` relative paths, and
trailing-`/` prefix matching.  Note that the condition never matches
in a bare repository.  Also add usage examples alongside the existing
`gitdir` examples.

[PATCH v2 3/3] t1305: add tests for includeIf "worktree"

[Chen Linxuan]

Cover the following scenarios unique to the "worktree" condition
(path matching features such as glob, tilde, icase are already
exercised by the gitdir tests):

  - bare repository (condition must not match)
  - multiple worktrees: main and linked worktrees each match their
    own path-based condition while sharing a single config file;
    a third linked worktree verifies directory-prefix matching with
    a trailing slash
  - symlinked worktree: the path is resolved before matching
