Subject: bug#10257: 23.3.1 Cygwin: network drives - file is write protected (false positive)
Date: Tue, 13 Dec 2011 10:12:46 -0500 [thread overview]
Message-ID: <4EE76B6E.7070904@cornell.edu> (raw)
In-Reply-To: <E1RaTZh-0006H7-3R@fencepost.gnu.org>
I have a question about the emacs side of this. I wonder what the
rationale is for testing writability before trying to save the file, and
then asking the user for confirmation in case the (unreliable) test for
writability fails (*).
It might be reasonable to just assume that the user really wants to save
the file; the worst thing that can happen is that the write fails. Am I
missing something?
Ken
(*) According to the documentation at
http://www.kernel.org/doc/man-pages/online/pages/man3/euidaccess.3.html
euidaccess() and access () are not reliable for checking permissions.
The advice there is to simply try the desired operation and check for
errors.
