From: Junio C Hamano Date: Wed, 10 Feb 2016 22:20:05 +0000 (-0800) Subject: Merge branch 'nd/do-not-move-worktree-manually' X-Git-Tag: v2.8.0-rc0~65 X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/d0a1cbccab54d828be2d83acc73f38c162962966?hp=-c Merge branch 'nd/do-not-move-worktree-manually' "git worktree" had a broken code that attempted to auto-fix possible inconsistency that results from end-users moving a worktree to different places without telling Git (the original repository needs to maintain backpointers to its worktrees, but "mv" run by end-users who are not familiar with that fact will obviously not adjust them), which actually made things worse when triggered. * nd/do-not-move-worktree-manually: worktree: stop supporting moving worktrees manually worktree.c: fix indentation --- d0a1cbccab54d828be2d83acc73f38c162962966 diff --combined setup.c index 2c4b22c845,2e9cc73af0..0deb02238b --- a/setup.c +++ b/setup.c @@@ -5,7 -5,6 +5,7 @@@ static int inside_git_dir = -1; static int inside_work_tree = -1; static int work_tree_config_is_bogus; +static struct string_list unknown_extensions = STRING_LIST_INIT_DUP; /* * The input parameter must contain an absolute path, and it must already be @@@ -312,23 -311,6 +312,23 @@@ done return ret; } +int is_nonbare_repository_dir(struct strbuf *path) +{ + int ret = 0; + int gitfile_error; + size_t orig_path_len = path->len; + assert(orig_path_len != 0); + strbuf_complete(path, '/'); + strbuf_addstr(path, ".git"); + if (read_gitfile_gently(path->buf, &gitfile_error) || is_git_directory(path->buf)) + ret = 1; + if (gitfile_error == READ_GITFILE_ERR_OPEN_FAILED || + gitfile_error == READ_GITFILE_ERR_READ_FAILED) + ret = 1; + strbuf_setlen(path, orig_path_len); + return ret; +} + int is_inside_git_dir(void) { if (inside_git_dir < 0) @@@ -374,25 -356,10 +374,25 @@@ void setup_work_tree(void static int check_repo_format(const char *var, const char *value, void *cb) { + const char *ext; + if (strcmp(var, "core.repositoryformatversion") == 0) repository_format_version = git_config_int(var, value); else if (strcmp(var, "core.sharedrepository") == 0) shared_repository = git_config_perm(var, value); + else if (skip_prefix(var, "extensions.", &ext)) { + /* + * record any known extensions here; otherwise, + * we fall through to recording it as unknown, and + * check_repository_format will complain + */ + if (!strcmp(ext, "noop")) + ; + else if (!strcmp(ext, "preciousobjects")) + repository_format_precious_objects = git_config_bool(var, value); + else + string_list_append(&unknown_extensions, ext); + } return 0; } @@@ -403,8 -370,6 +403,8 @@@ static int check_repository_format_gent config_fn_t fn; int ret = 0; + string_list_clear(&unknown_extensions, 0); + if (get_common_dir(&sb, gitdir)) fn = check_repo_format; else @@@ -422,46 -387,20 +422,35 @@@ * is a good one. */ git_config_early(fn, NULL, repo_config); - if (GIT_REPO_VERSION < repository_format_version) { + if (GIT_REPO_VERSION_READ < repository_format_version) { if (!nongit_ok) die ("Expected git repo version <= %d, found %d", - GIT_REPO_VERSION, repository_format_version); + GIT_REPO_VERSION_READ, repository_format_version); warning("Expected git repo version <= %d, found %d", - GIT_REPO_VERSION, repository_format_version); + GIT_REPO_VERSION_READ, repository_format_version); warning("Please upgrade Git"); *nongit_ok = -1; ret = -1; } + + if (repository_format_version >= 1 && unknown_extensions.nr) { + int i; + + if (!nongit_ok) + die("unknown repository extension: %s", + unknown_extensions.items[0].string); + + for (i = 0; i < unknown_extensions.nr; i++) + warning("unknown repository extension: %s", + unknown_extensions.items[i].string); + *nongit_ok = -1; + ret = -1; + } + strbuf_release(&sb); return ret; } - static void update_linked_gitdir(const char *gitfile, const char *gitdir) - { - struct strbuf path = STRBUF_INIT; - struct stat st; - - strbuf_addf(&path, "%s/gitdir", gitdir); - if (stat(path.buf, &st) || st.st_mtime + 24 * 3600 < time(NULL)) - write_file(path.buf, "%s", gitfile); - strbuf_release(&path); - } - /* * Try to read the location of the git directory from the .git file, * return path to git directory if found. @@@ -531,7 -470,6 +520,6 @@@ const char *read_gitfile_gently(const c error_code = READ_GITFILE_ERR_NOT_A_REPO; goto cleanup_return; } - update_linked_gitdir(path, dir); path = real_path(dir); cleanup_return:
