I noticed that my ~/.xsession-errors file had grown to over a
megabyte, even though I'd restarted X earlier today. Checking the
changelog, I found this:
"* Modify Xsession to always append to the error file, closing a temporary
file race condition window if it has to fall back to using tempfile(1) to
create an X session error file. Because it always appends now, log the
fact that the session has started, the username, and the date to the X
session error file once it is successfully opened. Document this change
in behavior in Xsession(5)."
Ok, that makes perfect sense if the error file is created by
tempfile(1), and lives in /tmp. But by default, it's not and it
doesn't. And people are used to the error file getting truncated.
The new always-append behavior is going to surprise a lot of people,
and upset a few. So, I'd like to toss out the suggestion that we go
back to truncating the file in the default case (not in /tmp).
I even made a patch for your consideration. (It can be modified to
use "echo -n > $ERRFILE" or "cat /dev/null > $ERRFILE" if my idiom of
": > $ERRFILE" seems too obscure.) I don't have a patch for
Xsession(5), but I could probably be persuaded to come up with one if
necessary.
