While looking at a different codebase, I was made (re)aware that the
ordering for APR to find the temp directory uses the following ordering
in env-vars:
$TMP
$TEMP
$TMPDIR
with the rationale that "this is how Python 2.2 does it"
But really, the canonical var to use is $TMPDIR, and looking
over Python 2.6 (at least) does revise the ordering to be what
"should" be expected....
for envname in 'TMPDIR', 'TEMP', 'TMP':
dirname = _os.getenv(envname)
if dirname: dirlist.append(dirname)
Anyone have heartburn if I "fix" tempdir.c ?
