Since we're returning a boolean about validation, the name is more properly "is valid".

Introduce `git_fs_path`, which operates on generic filesystem paths. `git_path` will be kept for only git-specific path functionality (for example, checking for `.git` in a path).

libgit2 has two distinct requirements that were previously solved by `git_buf`. We require: 1. A general purpose string class that provides a number of utility APIs for manipulating data (eg, concatenating, truncating, etc). 2. A structure that we can use to return strings to callers that they can take ownership of. By using a single class (`git_buf`) for both of these purposes, we have confused the API to the point that refactorings are difficult and reasoning about correctness is also difficult. Move the utility class `git_buf` to be called `git_str`: this represents its general purpose, as an internal string buffer class. The name also is an homage to Junio Hamano ("gitstr"). The public API remains `git_buf`, and has a much smaller footprint. It is generally only used as an "out" param with strict requirements that follow the documentation. (Exceptions exist for some legacy APIs to avoid breaking callers unnecessarily.) Utility functions exist to convert a user-specified `git_buf` to a `git_str` so that we can call internal functions, then converting it back again.

Filters use a short-lived structure to keep state during an operation to allow for caching and avoid unnecessary reallocations. This was previously called the "filter options", despite the fact that they contain no configurable options. Rename them to a "filter session" in keeping with an "attribute session", which more accurately describes their use (and allows us to create "filter options" in the future).

The `git_buf_text` namespace is unnecessary and strange. Remove it, just keep the functions prefixed with `git_buf`.

Introduce `git_filter_list__convert_buf` which behaves like the old implementation of `git_filter_list__apply_data`, where it might move the input data buffer over into the output data buffer space for efficiency. This new implementation will do so in a more predictible way, always freeing the given input buffer (either moving it to the output buffer or filtering it into the output buffer first). Convert internal users to it.

Ensure that we are validating working directory paths before we try to write to them.
Edward Thomson committed -
We're not necessarily checking out into the working directory. We could be checking out into an arbitrary location. Ensure that when we are writing conflict data that we do it in the checkout target.

If we want to validate more and different types of paths, the name `git_path_validate` makes that easier and more expressive. We can add, for example, `git_path_validate_foo` while the current name makes that less ergonomic.

When compiling libgit2 with -DDEPRECATE_HARD, we add a preprocessor definition `GIT_DEPRECATE_HARD` which causes the "git2/deprecated.h" header to be empty. As a result, no function declarations are made available to callers, but the implementations are still available to link against. This has the problem that function declarations also aren't visible to the implementations, meaning that the symbol's visibility will not be set up correctly. As a result, the resulting library may not expose those deprecated symbols at all on some platforms and thus cause linking errors. Fix the issue by conditionally compiling deprecated functions, only. While it becomes impossible to link against such a library in case one uses deprecated functions, distributors of libgit2 aren't expected to pass -DDEPRECATE_HARD anyway. Instead, users of libgit2 should manually define GIT_DEPRECATE_HARD to hide deprecated functions. Using "real" hard deprecation still makes sense in the context of CI to test we don't use deprecated symbols ourselves and in case a dependant uses libgit2 in a vendored way and knows it won't ever use any of the deprecated symbols anyway.

We've accumulated quite some functions which are never used outside of their respective code unit, but which are lacking the `static` keyword. Add it to reduce their linkage scope and allow the compiler to optimize better.

With commit 05f69012 (checkout: remove blocking dir when FORCEd, 2015-03-31), the last case was removde that actually queued a deferred removal. This is now more than five years in the past and nobody complained, so we can rest quite assured that the deferred removal is not really needed at all. Let's remove all related code to simplify the already complicated checkout logic.

When trying to determine whether a file changed, we try to avoid heavy operations by fist taking a look at the index, seeing whether the index entry is modified already. This doesn't seem to cut it, though, as we currently have the racy checkout::index::can_disable_pathspec_match test case: sometimes the files get restored to their original contents, sometimes they aren't. The issue is caused by a racy index [1]: in case we modify a file, add it to the index and then modify it again in-place without changing its file, then we may end up with a modified file that has the same stat(3P) info as we've currently got it in its corresponding index entry. The mitigation for this is to treat files with the same mtime as the index are treated as racily modified. We already have this logic in place for the index, but not when doing a checkout. Fix the issue by only consulting the index entry in case it has an older mtime as the index. Previously, the following script reliably had at least 20 failures, while now there is no failure to be observed anymore: ```bash j=0 for i in $(seq 100) do if ! ./libgit2_clar -scheckout::index::can_disable_pathspec_match >/dev/null then j=$(($j + 1)) fi done echo "Failures: $j" ``` [1]: https://git-scm.com/docs/racy-git

The checkout code didn't iterate into a subdir if it didn't match the pathspec, but since the pathspec might match files in the subdir we should recurse into it (In contrast to gitignore handling). Fixes #5089
Segev Finer committed -
We were previously applying the pathspec filter for the baseline iterator during checkout, as well as the target tree. This was an oversight; in fact, we should apply the pathspec filter to _all_ checkout targets, not just trees. Add a helper function to set the iterator pathspecs from the given checkout pathspecs, and call it everywhere.

The Windows Subsystem for Linux (WSL) is getting increasingly popular, in particular because it makes it _so_ easy to run Linux software on Windows' files, via the auto-mounted Windows drives (`C:\` is mapped to `/mnt/c/`, no need to set that up manually). Unfortunately, files/directories on the Windows drives can be accessed via their _short names_, if that feature is enabled (which it is on the `C:` drive by default). Which means that we have to safeguard even our Linux users against the short name attacks. Further, while the default options of CIFS/SMB-mounts seem to disallow accessing files on network shares via their short names on Linux/macOS, it _is_ possible to do so with the right options. So let's just safe-guard against short name attacks _everywhere_. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

On most platforms it's fine to create symlinks to nonexisting files. Not so on Windows, where the type of a symlink (file or directory) needs to be set at creation time. So depending on whether the target file exists or not, we may end up with different symlink types. This creates a problem when performing checkouts, where we simply iterate over all blobs that need to be updated without treating symlinks any special. If the target file of the symlink is going to be checked out after the symlink itself, then the symlink will be created as directory symlink and not as file symlink. Fix the issue by iterating over blobs twice: once to perform postponed deletions and updates to non-symlink blobs, and once to perform updates to symlink blobs.

In libgit2 nomenclature, when we need to verb a direct object, we name a function `git_directobject_verb`. Thus, if we need to init an options structure named `git_foo_options`, then the name of the function that does that should be `git_foo_options_init`. The previous names of `git_foo_init_options` is close - it _sounds_ as if it's initializing the options of a `foo`, but in fact `git_foo_options` is its own noun that should be respected. Deprecate the old names; they'll now call directly to the new ones.

Currently, the lifecycle functions for maps (allocation, deallocation, resize) are not named in a uniform way and do not have a uniform function signature. Rename the functions to fix that, and stick to libgit2's naming scheme of saying `git_foo_new`. This results in the following new interface for allocation: - `int git_<t>map_new(git_<t>map **out)` to allocate a new map, returning an error code if we ran out of memory - `void git_<t>map_free(git_<t>map *map)` to free a map - `void git_<t>map_clear(git<t>map *map)` to remove all entries from a map This commit also fixes all existing callers.

If the index is dirty, allow `GIT_CHECKOUT_FORCE` to obliterate unsaved changes. This is in keeping with its name and description.
Edward Thomson committed -
Now that the index has a "dirty" state, where it has changes that have not yet been committed or rolled back, our tests need to be adapted to actually commit or rollback the changes instead of assuming that the index can be operated on in its indeterminate state.

Always set the `index` in the `checkout_data`, even in the case that we are not reloading the index. Other functionality in checkout examines the index (for example: determining whether the workdir is modified) and we need it even in the (uncommon) case that we are not reloading.

Any part of the library which asks the question can pass in the mode to have it checked against `.gitmodules` being a symlink. This is particularly relevant for adding entries to the index from the worktree and for checking out files.
