From: Junio C Hamano Date: Wed, 8 May 2019 15:37:23 +0000 (+0900) Subject: Merge branch 'km/empty-repo-is-still-a-repo' X-Git-Tag: v2.22.0-rc0~32 X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/4ab701b2eec46ab5cbfe8c9732897e5d100184d8?ds=inline;hp=-c Merge branch 'km/empty-repo-is-still-a-repo' Running "git add" on a repository created inside the current repository is an explicit indication that the user wants to add it as a submodule, but when the HEAD of the inner repository is on an unborn branch, it cannot be added as a submodule. Worse, the files in its working tree can be added as if they are a part of the outer repository, which is not what the user wants. These problems are being addressed. * km/empty-repo-is-still-a-repo: add: error appropriately on repository with no commits dir: do not traverse repositories with no commits submodule: refuse to add repository with no commits --- 4ab701b2eec46ab5cbfe8c9732897e5d100184d8 diff --combined dir.c index ad30a5a46d,a4e59eb351..0a3ddcf2bc --- a/dir.c +++ b/dir.c @@@ -502,7 -502,8 +502,7 @@@ int submodule_path_match(const struct i } int report_path_error(const char *ps_matched, - const struct pathspec *pathspec, - const char *prefix) + const struct pathspec *pathspec) { /* * Make sure all pathspec matched;
