From: Chris Torek <chris.torek@xxxxxxxxx> 'git mv' has always complained about renaming a conflicted file, as it cannot handle multiple index entries for one file. However, the error message it uses has been the same as the one for an untracked file: fatal: not under version control, src=... which is patently wrong. Distinguish the two cases and add a test to make sure we produce the correct message. Signed-off-by: Chris Torek <chris.torek@xxxxxxxxx> --- git-mv: improve error message for conflicted file 'git mv' has always complained about renaming a conflicted file, as it cannot handle multiple index entries for one file. However, the error message it uses has been the same as the one for an untracked file: fatal: not under version control, src=... which is patently wrong. Distinguish the two cases and add a test to make sure we produce the correct message. Signed-off-by: Chris Torek chris.torek@xxxxxxxxx [chris.torek@xxxxxxxxx] ------------------------------------------------------------------------ Tests updated, and took Junio's suggestion to reduce the cache lookup to one call. I put in the shortened "conflicted" here but did not shorten the existing "not under version control" message (to minimize the visible and translations-required changes). I like the idea of renaming all stages and keeping them at their current stages, but that's too much for this patch. I'll be traveling next week and not sure if I will get to any followups for a while.
