With --temp (or --stage=all, which implies --temp), checkout-index writes a list to stdout associating temporary file names to the entries' names. But if it fails to write an entry, and the failure happens before even assigning a temporary filename to that entry, we get an odd output line. This can be seen when trying to check out a symlink whose blob is missing: $ missing_blob=$(git hash-object --stdin </dev/null) $ git update-index --add --cacheinfo 120000,$missing_blob,foo $ git checkout-index --temp foo error: unable to read sha1 file of foo (e69de29bb2d1d6434b8b29ae775ad8c2e48c5391) foo The 'TAB foo' line is not much useful and it might break scripts that expect the 'tempname TAB foo' output. So let's omit such entries from the stdout list (but leaving the error message on stderr). We could also consider omitting _all_ failed entries from the output list, but that's probably not a good idea as the associated tempfiles may have been created even when checkout failed, so scripts may want to use the output list for cleanup.
