# [PATCH 2/3] bash prompt: remove a redundant command line option 4 messages from 2015-11-21 to 2015-11-21. Participants: SZEDER Gábor. Thread: https://gitlist.dev/t/40849 ## SZEDER Gábor, 2015-11-21 11:30 Subject: [PATCH 1/3] bash prompt: test dirty index and worktree while on an orphan branch Message-ID: <1448105409-4494-1-git-send-email-szeder@ira.uka.de> URL: https://gitlist.dev/e/1448105409-4494-1-git-send-email-szeder%40ira.uka.de ``` There is only a single test exercising the dirty state indicator on an orphan branch, and in that test neither the index nor the worktree are dirty. Add two failing tests to check the dirty state indicator while either the index is dirty or while both the index and the worktree are dirty on an orphan branch, and to show that the dirtiness of the index is not displayed in these cases (the forth combination, i.e. clean index and dirty worktree are impossible on an orphan branch). Update the existing dirty state indicator on clean orphan branch test to match the style of the two new tests, most importantly to use 'git checkout --orphan' instead of cd-ing into a repository that just happens to be empty and clean.

To check the dirtiness of the index, __git_ps1() runs 'git diff-index --cached ... HEAD', which doesn't work on an orphan branch, because HEAD doesn't point to a valid commit. Run 'git diff ... --cached' instead, as it does the right thing both on valid and invalid HEAD, i.e. compares the index to the existing HEAD in the former case and to the empty tree in the latter. This fixes the two failing tests added in the first commit of this series. The dirtiness of the worktree is already checked with 'git diff' and is displayed correctly even on an orphan branch.
