This adds index as a prerequisite for directory listing (with exclude). At the moment directory listing is used by "git clean", "git add", "git ls-files" and "git status"/"git commit" and unpack_trees()-related commands. These commands have been checked/modified to populate index before doing directory listing. add_excludes_from_file() does not enable this feature, because it is used to read .git/info/exclude and some explicit files specified by "git ls-files".

directory listing API
|
|
=====================
|
|
|
|
The directory listing API is used to enumerate paths in the work tree,
|
|
optionally taking `.git/info/exclude` and `.gitignore` files per
|
|
directory into account.
|
|
|
|
Data structure
|
|
--------------
|
|
|
|
`struct dir_struct` structure is used to pass directory traversal
|
|
options to the library and to record the paths discovered. The notable
|
|
options are:
|
|
|
|
`exclude_per_dir`::
|
|
|
|
The name of the file to be read in each directory for excluded
|
|
files (typically `.gitignore`).
|
|
|
|
`collect_ignored`::
|
|
|
|
Include paths that are to be excluded in the result.
|
|
|
|
`show_ignored`::
|
|
|
|
The traversal is for finding just ignored files, not unignored
|
|
files.
|
|
|
|
`show_other_directories`::
|
|
|
|
Include a directory that is not tracked.
|
|
|
|
`hide_empty_directories`::
|
|
|
|
Do not include a directory that is not tracked and is empty.
|
|
|
|
`no_gitlinks`::
|
|
|
|
If set, recurse into a directory that looks like a git
|
|
directory. Otherwise it is shown as a directory.
|
|
|
|
The result of the enumeration is left in these fields::
|
|
|
|
`entries[]`::
|
|
|
|
An array of `struct dir_entry`, each element of which describes
|
|
a path.
|
|
|
|
`nr`::
|
|
|
|
The number of members in `entries[]` array.
|
|
|
|
`alloc`::
|
|
|
|
Internal use; keeps track of allocation of `entries[]` array.
|
|
|
|
|
|
Calling sequence
|
|
----------------
|
|
|
|
Note: index may be looked at for .gitignore files that are CE_SKIP_WORKTREE
|
|
marked. If you to exclude files, make sure you have loaded index first.
|
|
|
|
* Prepare `struct dir_struct dir` and clear it with `memset(&dir, 0,
|
|
sizeof(dir))`.
|
|
|
|
* Call `add_exclude()` to add single exclude pattern,
|
|
`add_excludes_from_file()` to add patterns from a file
|
|
(e.g. `.git/info/exclude`), and/or set `dir.exclude_per_dir`. A
|
|
short-hand function `setup_standard_excludes()` can be used to set up
|
|
the standard set of exclude settings.
|
|
|
|
* Set options described in the Data Structure section above.
|
|
|
|
* Call `read_directory()`.
|
|
|
|
* Use `dir.entries[]`.
