From 7c3a4a7f07bc0d7fb552b75be6a71d43b8d3bb23 Mon Sep 17 00:00:00 2001 From: Ben Straub Date: Fri, 30 Mar 2012 12:26:39 -0700 Subject: [PATCH] t12-repo.c ported, although kind of messy. It'd be nice to be rid of all the #define's, but converting to const char*'s would be even messier, and less declarative. --- tests-clar/repo/discover.c | 155 +++++++++++++++++++++++++++++++++++++ 1 file changed, 155 insertions(+) create mode 100644 tests-clar/repo/discover.c diff --git a/tests-clar/repo/discover.c b/tests-clar/repo/discover.c new file mode 100644 index 000000000..7281e872b --- /dev/null +++ b/tests-clar/repo/discover.c @@ -0,0 +1,155 @@ +#include "clar_libgit2.h" + +#include "odb.h" +#include "repository.h" + + +#define TEMP_REPO_FOLDER "temprepo/" +#define DISCOVER_FOLDER TEMP_REPO_FOLDER "discover.git" + +#define SUB_REPOSITORY_FOLDER_NAME "sub_repo" +#define SUB_REPOSITORY_FOLDER DISCOVER_FOLDER "/" SUB_REPOSITORY_FOLDER_NAME +#define SUB_REPOSITORY_FOLDER_SUB SUB_REPOSITORY_FOLDER "/sub" +#define SUB_REPOSITORY_FOLDER_SUB_SUB SUB_REPOSITORY_FOLDER_SUB "/subsub" +#define SUB_REPOSITORY_FOLDER_SUB_SUB_SUB SUB_REPOSITORY_FOLDER_SUB_SUB "/subsubsub" + +#define REPOSITORY_ALTERNATE_FOLDER DISCOVER_FOLDER "/alternate_sub_repo" +#define REPOSITORY_ALTERNATE_FOLDER_SUB REPOSITORY_ALTERNATE_FOLDER "/sub" +#define REPOSITORY_ALTERNATE_FOLDER_SUB_SUB REPOSITORY_ALTERNATE_FOLDER_SUB "/subsub" +#define REPOSITORY_ALTERNATE_FOLDER_SUB_SUB_SUB REPOSITORY_ALTERNATE_FOLDER_SUB_SUB "/subsubsub" + +#define ALTERNATE_MALFORMED_FOLDER1 DISCOVER_FOLDER "/alternate_malformed_repo1" +#define ALTERNATE_MALFORMED_FOLDER2 DISCOVER_FOLDER "/alternate_malformed_repo2" +#define ALTERNATE_MALFORMED_FOLDER3 DISCOVER_FOLDER "/alternate_malformed_repo3" +#define ALTERNATE_NOT_FOUND_FOLDER DISCOVER_FOLDER "/alternate_not_found_repo" + +static int ensure_repository_discover(const char *start_path, const char *ceiling_dirs, const char *expected_path) +{ + int error; + char found_path[GIT_PATH_MAX]; + + error = git_repository_discover(found_path, sizeof(found_path), start_path, 0, ceiling_dirs); + //across_fs is always 0 as we can't automate the filesystem change tests + + if (error < GIT_SUCCESS) + return error; + + return strcmp(found_path, expected_path) ?
