Hi Joey,
in #920118 [1], users of sponge complained about sponge not preserving
file ownership of the output file. They argued, that sponge should
behave (more) like 'tee' and shell redirections. And they interpreted
the sentence
"sponge preserves the permissions of the output file if it
already exists."
from sponge(1) as 'sponge preserves permissions and ownership [...]'.
After thinking about it several times, I am still ambiguous; thus, I am
sending you two patches:
0001: an attempt to clarify the wording such that is becomes (more)
clear that file ownership will not be preserved.
and
0002: (might be squashed with 0001) a patch to sponge.c that
introduces the attempt to restore the original file ownership
opportunistically, neither handling nor even checking for
errors.
I am really curious about your comments, and whether you'd like to
handle the complaints somehow.
Looking forward for your reply.
Thanks and kind regards,
Nicolas
