t2027-worktree-list has an incorrect expectation for --git-common-dir
which has been adjusted and marked to expect failure. Some of the tests added have been marked to expect failure. These demonstrate a problem with the way that some options to git rev-parse behave when executed from a subdirectory of the main worktree.

Executing `git-rev-parse` with `--git-common-dir`, `--git-path <path>`,
or `--shared-index-path` from the root of the main worktree results in a relative path to the git dir. When executed from a subdirectory of the main tree, it can incorrectly return a path which starts 'sub/path/.git'. Change this to return the proper relative path to the git directory. Related tests marked to expect failure are updated to expect success Signed-off-by: Michael Rappazzo <[hidden email]> --- builtin/rev-parse.c | 22 +++++++++++++++++----- t/t1500-rev-parse.sh | 4 ++-- t/t1700-split-index.sh | 2 +- t/t2027-worktree-list.sh | 4 ++-- 4 files changed, 22 insertions(+), 10 deletions(-) diff --git a/builtin/rev-parse.c b/builtin/rev-parse.c index c961b74..40579e0 100644 --- a/builtin/rev-parse.c +++ b/builtin/rev-parse.c @@ -564,10 +564,15 @@ int cmd_rev_parse(int argc, const char **argv, const char *prefix) } if (!strcmp(arg, "--git-path")) { + struct strbuf sb = STRBUF_INIT; + char *path; if (!argv[i + 1]) die("--git-path requires an argument"); - puts(git_path("%s", argv[i + 1])); - i++; + + path = xstrfmt("%s/%s", get_git_dir(), argv[++i]); + puts(relative_path(path, prefix, &sb)); + strbuf_release(&sb); + free(path); continue; } if (as_is) { @@ -787,8 +792,9 @@ int cmd_rev_parse(int argc, const char **argv, const char *prefix) continue; } if (!strcmp(arg, "--git-common-dir")) { - const char *pfx = prefix ? prefix : ""; - puts(prefix_filename(pfx, strlen(pfx), get_git_common_dir())); + struct strbuf sb = STRBUF_INIT; + puts(relative_path(get_git_common_dir(), prefix, &sb)); + strbuf_release(&sb); continue; } if (!strcmp(arg, "--is-inside-git-dir")) { @@ -811,7 +817,13 @@ int cmd_rev_parse(int argc, const char **argv, const char *prefix) die(_("Could not read the index")); if (the_index.split_index) { const unsigned char *sha1 = the_index.split_index->base_sha1; - puts(git_path("sharedindex.%s", sha1_to_hex(sha1))); + struct strbuf sb = STRBUF_INIT; + char *path; + + path = xstrfmt("%s/sharedindex.%s", get_git_dir(), sha1_to_hex(sha1)); + puts(relative_path(path, prefix, &sb)); + strbuf_release(&sb); + free(path); } continue; } diff --git a/t/t1500-rev-parse.sh b/t/t1500-rev-parse.sh index f39f783..d74f09a 100755 --- a/t/t1500-rev-parse.sh +++ b/t/t1500-rev-parse.sh @@ -93,7 +93,7 @@ test_expect_success 'git-common-dir from worktree root' ' test_cmp expect actual ' -test_expect_failure 'git-common-dir inside sub-dir' ' +test_expect_success 'git-common-dir inside sub-dir' ' mkdir -p path/to/child && test_when_finished "rm -rf path" && echo "$(git -C path/to/child rev-parse --show-cdup).git" >expect && @@ -107,7 +107,7 @@ test_expect_success 'git-path from worktree root' ' test_cmp expect actual ' -test_expect_failure 'git-path inside sub-dir' ' +test_expect_success 'git-path inside sub-dir' ' mkdir -p path/to/child && test_when_finished "rm -rf path" && echo "$(git -C path/to/child rev-parse --show-cdup).git/objects" >expect && diff --git a/t/t1700-split-index.sh b/t/t1700-split-index.sh index 8ca21bd..d2d9e02 100755 --- a/t/t1700-split-index.sh +++ b/t/t1700-split-index.sh @@ -200,7 +200,7 @@ EOF test_cmp expect actual ' -test_expect_failure 'rev-parse --shared-index-path' ' +test_expect_success 'rev-parse --shared-index-path' ' rm -rf .git && test_create_repo . && git update-index --split-index && diff --git a/t/t2027-worktree-list.sh b/t/t2027-worktree-list.sh index 53cc5d3..16eec6e 100755 --- a/t/t2027-worktree-list.sh +++ b/t/t2027-worktree-list.sh @@ -8,7 +8,7 @@ test_expect_success 'setup' ' test_commit init ' -test_expect_failure 'rev-parse --git-common-dir on main worktree' ' +test_expect_success 'rev-parse --git-common-dir on main worktree' ' git rev-parse --git-common-dir >actual && echo .git >expected && test_cmp expected actual && @@ -18,7 +18,7 @@ test_expect_failure 'rev-parse --git-common-dir on main worktree' ' test_cmp expected2 actual2 ' -test_expect_failure 'rev-parse --git-path objects linked worktree' ' +test_expect_success 'rev-parse --git-path objects linked worktree' ' echo "$(git rev-parse --show-toplevel)/.git/worktrees/linked-tree/objects" >expect && test_when_finished "rm -rf linked-tree && git worktree prune" && git worktree add --detach linked-tree master && -- 2.8.0 -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to [hidden email] More majordomo info at http://vger.kernel.org/majordomo-info.html |

Especially when there is other flag telling you whether you are in the main or another worktree, so comparing the output for --git-dir and --git-common-dir is the easiest way to do so, but then you have to normalize them on their own because git returns different values pointing to the same directory.
