Hello.

Some of the tests do not delete the directories the create. I guess that's a
bug in the scripts on DOS and I should try to diagnose those cases.

But if you want to debug the test failures under DOS, you could change the
tests to leave the test files rather than deleting them. Then it's possible
the names would collide, say if $$ == 11131 in the 1st run and $$ == 11198 in
the 2nd run. From this point-of-view it would be good if the temporary files
and directories could be renamed to aaaXXXXX where aaa = some prefix and XXXXX
= $$.

I'll take a look for any uses of $TMPDIR. Perhaps the 'df' uses it. I
certainly seem to remember it displaying something with $TMPDIR in it, when I
hadn't set $CANDIDATE_TMP_DIRS.

How about doing the tests in subdirectories named after the tests? E.g.:
backup-file.tmp. Then the prefix wouldn't matter so much, since it's clear
from the directory name what test it's from. This would also have the
advantage that all the temporary files could be cleaned up easily, since
they'd be separate from the test scripts, Makefiles, etc.

Thanks, bye, Rich =]
