Subject: [PATCH] git-mv: improve error message for conflicted file
Date: Fri, 17 Jul 2020 23:24:53 +0000 [thread overview]
Message-ID: <pull.678.git.1595028293855.gitgitgadget@gmail.com> (raw)
From: Chris Torek <chris.torek@gmail.com>
'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.

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.

------------------------------------------------------------------------
A small note on the test: I originally had a different message text, so
the grep is slightly more general than necessary here. This leaves room
for a better message, though; I'm not sure mine is that great.
The error messages in general from 'git mv' could probably stand a lot
of cleanup. This is just a minimal fix for some particularly bad
behavior.
