ESUG saw a lot of progress for Exupery. There is now a preliminary
Mac port and 2 bugs were fixed. There is a Mac VM available here:
http://wiki.squeak.org/squeak/3945
This version is compiled without optimisation. It looks like there's a
bug in GCC 4.0.1 which is preventing sends from working in Exupery.
Exupery works fine with gcc 3.3.3 and gcc 4.1.2. Hopefully there will
be a more polished Mac VM soon compiled with optimisations. Thanks to
Matthieu for building this.
Two bugs were fixed. The major bug was due Exupery overflowing
the root table, this was the one that was causing the crashes that
I was debugging. There was a minor bug that was due to failing to
mark Exupery's interpreter integration objects which as far as I'm
aware has never caused a crash, it's fixed too.
I'm starting to think about the next release seriously as I'm
hopeful that it's only one bug fix away. The pre-release tasks
are:
* Fix the current bug
* Test that Exupery can compile in the background for an hour
* Check that the stress test still runs
* Get Exupery installing from Package Universes
* Build an Exupery development package on Package Universes
* Integrate the 2G VM fixes from Dave and John.
I'd like to make it easier to build Exupery development images,
Exupery's development tools use more packages than Exupery needs to
run. The two things that need to be done is automating the build and
making sure that the catalogue has up to date pointers to to
packages. Some packages still point to the old minnow location for the
Squeak swiki.
I'd also like to integrate the 2G unsigned pointer comparison fixes
as they were causing crashes on my laptop after fixing the root table
bugs. At the time, I thought it was image corruption which is
plausible after debugging a GC related bug.
