I double checked; contrary to the docstring's promise, no error is
returned in this case. I try to fix the docstring in the patch below by
removing the distinction between "Path does not exist" and "Path's parent
does not exist" and redefining the "error" and "svn_node_unknown" cases to
match svn_node_kind_t's documentation.
I'll commit in a few days, but posting here for sanity check.
[[[
Follow up to r30937.
* subversion/include/svn_io.h
(svn_io_check_path): Try again to match the docstring to the
implementation.
]]]
The complete patched docstring is:
/** Determine the @a kind of @a path. @a path should be UTF-8 encoded.
*
* If @a path is a file, set @a *kind to @c svn_node_file.
*
* If @a path is a directory, set @a *kind to @c svn_node_dir.
*
* If @a path does not exist, set @a *kind to @c svn_node_none.
*
* If @a path exists but is none of the above, set @a *kind to @c
* svn_node_unknown.
*
* If unable to determine @a path's kind, return an error, with @a *kind's
* value undefined.
*
* Use @a pool for temporary allocations.
*
* @see svn_node_kind_t
*/
svn_error_t *svn_io_check_path(const char *path,
svn_node_kind_t *kind,
apr_pool_t *pool);
