Therefore, I don't feel your patch as is is ready for inclusion — much more work needed.
Fine. So I update my toplevel "run" script (attached) to make a separate asdf/ directory for each OS, thereby keeping things entirely partitioned but allowing to run the same toplevel script everywhere. This "run" script does an rsync -aL --delete in order to clone the asdf/ directory to the os-specific one, so it has the effect of starting with a fresh asdf directory every time (i.e. with the build/ directory cleared out). Also attached is another patch which protects the test-multiple.script from failure when the filesystem does not support symbolic links (e.g. in a virtualbox guest folder shared from the virtualbox host). This patch also adds the ability to set an ALLEGRO_NOISY environment variable so that Allegro on Windows will pop up the consoles (useful for cases when there are failures and you need to be able to capture the output). I am reliably replicating test-encoding.script failures now with alisp8 and mlisp8 on Windows and Linux. I will send that output separately. I am also still getting intermittent test-stamp-propagation failures, but these seem to be more rare since I am starting with clean asdf directory for each set of test runs. But the next time I do get one I will provide the output. -- My Best, Dave Cooper, Genworks Support david.cooper@genworks.com, dave.genworks.com(skype) USA: 248-327-3253(o), 1-248-330-2979(mobile) UK: 0191 645 1699
