Please ack if you can test it.

Bug report for Gnu Emacs
Version: 21.4.2
OS: Mandriva Linux 2006 Free
Filesystem: ext3

Scenario: overwriting (C-x C-w) an existing file, where the new file to be
written is larger than the available disk space on the filesystem where the
original file is kept.

Bug: after confirming that it is okay to overwrite the existing file, the
error message displayed is "file already exists".
Expected behavior: error message should read "No space left on device or
similar".

strace confirms that emacs is getting the right errno (ENOSPC) for the write
to the file handle.

Thanks,
Alex

I did the following:

   1.  emacs -Q

   2.  "C-x C-f /usr/te TAB fou TAB RET" to read a 4MB file from a 6MB
partition.

   3.  "C-x C-w tri TAB RET" to overwrite the existing zero-length
/usr/test/trial file.

   4.  "SPC" at the "File `/usr/test/trial' exists; overwrite? (y or n)"
prompt to confirm.

   5.  emacs responds with the following messages:

	Saving file /usr/test/trial...
	basic-save-buffer-2: IO error writing /usr/test/trial: No space left on device

This is on GNU/Linux (SuSE 9.0), where /usr/test/ is an ext3 partition,
using an Emacs built from CVS on 22-July; is that close enough?  I will
retest with a more up-to-date version, but that may take a while.

Do you mean that you tested this case and it did not fail?
Or that you were not able to test it?

I tried this with today's CVS in the MS-Windows port writing to a
floppy, and I cannot reproduce the problem: I get "No space left on
device", as expected.

Looks like that bug as been fixed already.  Thanks for testing it.

Thanks for testing.  It is good to know there is no bug there.
