From 5f959dca0d7d7d921ccf2948e0745659f6055148 Mon Sep 17 00:00:00 2001 From: John Fultz Date: Thu, 29 Dec 2016 19:26:50 -0600 Subject: [PATCH] Fix handling of GIT_CHECKOUT_DISABLE_PATHSPEC_MATCH flag. git_checkout_tree() sets up its working directory iterator to respect the pathlist if GIT_CHECKOUT_DISABLE_PATHSPEC_MATCH is present, which is great. What's not so great is that this iterator is then used side-by-side with an iterator created by git_checkout_iterator(), which did not set up its pathlist appropriately (although the iterator mirrors all other iterator options). This could cause git_checkout_tree() to delete working tree files which were not specified in the pathlist when GIT_CHECKOUT_DISABLE_PATHSPEC_MATCH was used, as the unsynchronized iterators causes git_checkout_tree() to think that files have been deleted between the two trees. Oops. And added a test which fails without this fix (specifically, the final check for "testrepo/README" to still be present fails). --- src/checkout.c | 4 ++++ tests/checkout/tree.c | 38 ++++++++++++++++++++++++++++++++++++++ 2 files changed, 42 insertions(+) diff --git a/src/checkout.c b/src/checkout.c index 62950913e..578695a37 100644 --- a/src/checkout.c +++ b/src/checkout.c @@ -2553,6 +2553,10 @@ int git_checkout_iterator( GIT_ITERATOR_IGNORE_CASE : GIT_ITERATOR_DONT_IGNORE_CASE; baseline_opts.start = data.pfx; baseline_opts.end = data.pfx; + if (opts && (opts->checkout_strategy & GIT_CHECKOUT_DISABLE_PATHSPEC_MATCH)) { + baseline_opts.pathlist.count = opts->paths.count; + baseline_opts.pathlist.strings = opts->paths.strings; + } if (data.opts.baseline_index) { if ((error = git_iterator_for_index( diff --git a/tests/checkout/tree.c b/tests/checkout/tree.c index 4a0314a9e..c9581fdc5 100644 --- a/tests/checkout/tree.c +++ b/tests/checkout/tree.c @@ -422,6 +422,44 @@ void test_checkout_tree__can_checkout_with_pattern(void) cl_assert(git_path_exists("testrepo/new.txt")); } +void test_checkout_tree__pathlist_checkout_ignores_non_matches(void) +{ + char *entries[] = { "branch_file.txt", "link_to_new.txt" }; + + /* reset to beginning of history (i.e. just a README file) */ + + g_opts.checkout_strategy = + GIT_CHECKOUT_FORCE | GIT_CHECKOUT_REMOVE_UNTRACKED; + + cl_git_pass(git_revparse_single(&g_object, g_repo, "refs/heads/master")); + + cl_git_pass(git_checkout_tree(g_repo, g_object, &g_opts)); + cl_git_pass(git_repository_set_head(g_repo, "refs/heads/master")); + + cl_assert(git_path_exists("testrepo/README")); + cl_assert(git_path_exists("testrepo/branch_file.txt")); + cl_assert(git_path_exists("testrepo/link_to_new.txt")); + cl_assert(git_path_exists("testrepo/new.txt")); + + cl_git_pass(git_revparse_single(&g_object, g_repo, "8496071c1b46c854b31185ea97743be6a8774479")); + + g_opts.checkout_strategy = + GIT_CHECKOUT_FORCE | GIT_CHECKOUT_DISABLE_PATHSPEC_MATCH; + g_opts.paths.strings = entries; + g_opts.paths.count = 2; + + cl_git_pass(git_checkout_tree(g_repo, g_object, &g_opts)); + + cl_assert(git_path_exists("testrepo/README")); + cl_assert(!git_path_exists("testrepo/branch_file.txt")); + cl_assert(!git_path_exists("testrepo/link_to_new.txt")); + cl_assert(git_path_exists("testrepo/new.txt")); + + git_object_free(g_object); + g_object = NULL; + +} + void test_checkout_tree__can_disable_pattern_match(void) { char *entries[] = { "b*.txt" };
