[asdf-devel] Old revisions of ASDF in the wild.

Which legacy versions of ASDF should we support?

Xach and/or one of his users had trouble with ASDF from SBCL 1.0.38.
# git show sbcl_1_0_38:contrib/asdf/asdf.lisp > /tmp/asdf-from-sbcl-1.0.38.lisp
# sha1sum /tmp/asdf-from-sbcl-1.0.38.lisp

We can identify which revision this came from with:
# git log sbcl_1_0_38 -- contrib/asdf/asdf.lisp
It was by nikodemus which claims to have imported it from git.
Of course, whichever revision is latest in asdf.git at that point was
not in master when nikodemus pulled, and
# for i in $(git rev-list HEAD -- asdf.lisp) ; do echo "$i $(git show
"$i":asdf.lisp | sha1sum)" ; done | grep
replies nothing. How come we can't see the same version anywhere in
the asdf git repo?
Let's find the version with least differences...
# for i in $(git rev-list HEAD -- asdf.lisp) ; do echo "$i $(git show
"$i":asdf.lisp | diff -uab - /tmp/asdf-from-sbcl-1.0.38.lisp | grep
'^[+-]' | wc -l)" ; done | sort -k2 | head -n 1

What, no difference? Yeah, it's SBCL whitespace canonicalization at work.
So the good version was a commit by gwking on 2009-06-09.

I'm too lazy to do anything systematic about it right now, but I
wanted to record that for posterity. Maybe at some point I'll scum
around the SBCL sources and try to extract a few versions of ASDF that
we may want to support. Are there any other implementations than SBCL,
ECL and ABCL that used to distribute copies of ASDF? We may want to do
something similar, and integrate that in our test suite.

Now to make sure that upgrades work from ALL these versions, before we
release 2.009... soupirs (le sigh).
