> All of this refactoring sounds interesting and many systems distribute a
core/kernel and then optionally allow you to download extensions, PHP for

into the kernel/core over time once they have proved their worth because
people don't particularly like downloading extensions.
As Jean-Sebastien pointed out this separation already exists in the make
system so the user can choose precisely which bits to build once the source
distro has been downloaded. In the case of the binary distro I think the
case will be that the system only picks up those extensions that you
reference in SCDL so that fact that you have installed all of them is not an
issue given the number of extensions we have now. I would therefore suggest
that the extra complexity of delivering physically separate tars for
extensions and kernel is not required for M3 particularly because Jeremy's
ideas are interesting and may lead to rehashing the details of how this is
done for M4 anyhow.
Simon
I think I'm leaning towards this strategy too now - keep a single
binary downloadable package - as Simon says "the system only picks up
those extensions that you reference in SCDL so that fact that you have
installed all of them is not an issue".
I do think we still need a name change, and "native" seems to be the
favourite. I'm happy with this - what do others think?
The only issue is with our samples - most of them require more than
one extension (e.g. the PythonCalculator shows the use of both the
Python and WS binding extensions) - maybe we should split some of them
up a bit more. With clear docs that explain what each sample requires
this should be OK.
So my proposal now is that the C++ M3 release provides source and
binary "Tuscany SCA Native" packages for Windows, Linux and Mac OSX,
with only the extensions (and their respective samples) that can be
built on that OS available within the package (e.g. no Axis WS binding
on Mac).
This has gone round in circles a bit - apologies for that! What do people think?
Cheers
Andy
