I am playing around with detached worktrees and have identified a number of bugs in the path handling. Specifically, it seems that while git-status and git-add/git-rm are consistent with respect to each other, they expose different behaviour in different scenarios. git-diff, on the other hand, seems broken with respect to worktree handling. Let me run you through what I did, bugs are identified with ###BUG. Output is prefixed with #, which should make it easier to cut-n-paste to reproduce Note how $GIT_DIR is set for the first part of this exercise: mkdir worktree GIT_DIR=repo.git; export GIT_DIR git --bare init # Initialized empty Git repository in repo.git/ git config core.bare false git config core.worktree ../worktree echo This is just a file called foo > worktree/foo git add worktree/foo # fatal: pathspec 'worktree/foo' did not match any files ###BUG: git should be able to factor out the common path prefix ls foo # ls: cannot access foo: No such file or directory git add foo # very confusing, but works git commit -m'initial checkin' # Created initial commit 2f2cdf3: initial checkin # 1 files changed, 1 insertions(+), 0 deletions(-) # create mode 100644 foo git status ## On branch master # nothing to commit (working directory clean) git diff # diff --git a/foo b/foo # deleted file mode 100644 # index 27b451e..0000000 # --- a/foo # +++ /dev/null # @@ -1 +0,0 @@ # -This is just a file called foo ###BUG: git-diff doesn't seem to honour worktree and thinks the file ###was deleted git diff -- worktree/foo ###BUG: no output, even though path was given echo Another line >> worktree/foo git status # # On branch master # # Changed but not updated: # # (use "git add <file>..." to update what will be committed) # # # # modified: foo # # # no changes added to commit (use "git add" and/or "git commit -a") git diff -- worktree/foo ###BUG: no output, even though path was given git add foo # diff --git a/foo b/foo # deleted file mode 100644 # index 76404d8..0000000 # --- a/foo # +++ /dev/null # @@ -1,2 +0,0 @@ # -This is just a file called foo # -Another line git diff --cached # diff --git a/foo b/foo # index 27b451e..76404d8 100644 # --- a/foo # +++ b/foo # @@ -1 +1,2 @@ # This is just a file called foo # +Another line ----------- If worktree is actually an ancestor of the Git repository *and* we chdir() into the repository, whether GIT_DIR is set or not, things look different again: mv ../worktree/* .. rmdir ../worktree git config core.worktree .. git status # # On branch master # # Changed but not updated: # # (use "git add <file>..." to update what will be committed) # # # # modified: ../foo # # # # Untracked files: # # (use "git add <file>..." to include in what will be committed) # # # # ./ # no changes added to commit (use "git add" and/or "git commit -a") git diff # diff --git a/foo b/foo # deleted file mode 100644 # index 76404d8..0000000 # --- a/foo # +++ /dev/null # @@ -1,2 +0,0 @@ # -This is just a file called foo # -Another line ###BUG: again, git-diff can't find the local file git add foo # fatal: pathspec 'repo.git/foo' did not match any files ###BUG: inconsistent with above behaviour, but consistent with ###git-status output git add ../foo git commit -m'another linee' # Created commit d016799: another linee # 1 files changed, 1 insertions(+), 0 deletions(-) -- martin | http://madduck.net/ | http://two.sentenc.es/ "i might disagree with what you have to say, but I'll defend to the death your right to say it." -- voltaire spamtraps: madduck.bogus@xxxxxxxxxxx
