From 44df2e297025d7a9af6c265dfefb687b09e2537a Mon Sep 17 00:00:00 2001 From: Jonathon Mah Date: Fri, 30 Dec 2011 16:14:01 -0800 Subject: stash: Don't fail if work dir contains file named 'HEAD' When performing a plain "git stash" (without --patch), git-diff would fail with "fatal: ambiguous argument 'HEAD': both revision and filename". The output was piped into git-update-index, masking the failed exit status. The output is now sent to a temporary file (which is cleaned up by existing code), and the exit status is checked. The "HEAD" arg to the git-diff invocation has been disambiguated too, of course. In patch mode, "git stash -p" would fail harmlessly, leaving the working dir untouched. Interactive adding is fine, but the resulting tree was diffed with an ambiguous 'HEAD' argument. Use >foo (no space) when redirecting output. In t3904, checks and operations on each file are in the order they'll appear when interactively staging. In t3905, fix a bug in "stash save --include-untracked -q is quiet": The redirected stdout file was considered untracked, and so was removed from the working directory. Use test path helper functions where appropriate.
