From 9e2326c7e1efb1ae42b17e3fa38c16711a8d0bd8 Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Sun, 28 Oct 2012 17:16:25 +0100 Subject: longest_ancestor_length(): require prefix list entries to be normalized Move the responsibility for normalizing prefixes from longest_ancestor_length() to its callers. Use slightly different normalizations at the two callers: In setup_git_directory_gently_1(), use the old normalization, which ignores paths that are not usable. In the next commit we will change this caller to also resolve symlinks in the paths from GIT_CEILING_DIRECTORIES as part of the normalization. In "test-path-utils longest_ancestor_length", use the old normalization, but die() if any paths are unusable. Also change t0060 to only pass normalized paths to the test program (no empty entries or non-absolute paths, strip trailing slashes from the paths, and remove tests that thereby become redundant). The point of this change is to reduce the scope of the ancestor_length tests in t0060 from testing normalization+longest_prefix to testing only mostly longest_prefix. This is necessary because when setup_git_directory_gently_1() starts resolving symlinks as part of its normalization, it will not be reasonable to do the same in the test suite, because that would make the test results depend on the contents of the root directory of the filesystem on which the test is run. HOWEVER: under Windows, bash mangles arguments that look like absolute POSIX paths into DOS paths. So we have to retain the level of normalization done by normalize_path_copy() to convert the bash-mangled DOS paths (which contain backslashes) into paths that use forward slashes.

But it turned out to be easier to use a function specialized for comparing path prefixes (i.e., one that knows about slashes and root paths) than to prepare the paths in such a way that a generic string prefix comparison function can be used. So delete string_list_longest_prefix() and its documentation and test cases.
