Subject: temp-file-name-pattern vs temporary-file-directory
Date: Thu, 29 Jan 2009 17:45:21 +0100

Recently I learned about the variable temp-file-name-pattern when
under odd circumstances I didn't have access to /tmp. I was
surprised that the default value of this variable was
/tmp/emacsXXXXXX, thus ignoring my setting of
temporary-file-directory. Shouldn't temp-file-name-pattern take into
account the value of temporary-file-directory?

It looks at $TMPDIR, at least for me.

Ah, $TMPDIR is an environment variable I didn't know about. I have
customized temporary-file-directory to point to a directory that is
used only by emacs. I would expect temp-file-name-pattern recognizes
such a setting, too.

It looks like temp-file-name-pattern is specific to call-process-region,
and predates temporary-file-directory.  call-process-region indeed
should be updated to use either make-temp-file or at least
temporary-file-directory.  And temp-file-name-pattern should be dropped.

I've removed temp-file-name-pattern, and changed call-process-region to
use temporary-file-directory.
