[squeak-dev] [ANN] Magma release 42

I am pleased to announce a new release of Magma.  Release 42 brings
unprecedented scale and availability of persistent domain models to
Squeak users.  In particular, a single logical repository can now be
served from multiple servers simultaneously, each hosting their own
physical copy.  To maintain consistency, just one server receives
writes and broacasts commit-records to "warm-backup" servers
asynchronously.  The warm-backups ensure to keep themselves constantly
up to date automatically.

Individual servers in the "Node", even the primary, can be brought
off-line and back on-line without disruption to clients.  Maintenance
routines such as full-backup and compression may optionally be run
while a repository is off-line, resulting in true 24x7 operation with
no performance degradation due to maintenance jobs.  The more physical
copies of a repository that are brought on-line, the more read-scale
the overall Node will provide.  For more details, see:

  http://wiki.squeak.org/squeak/6101

Scales up as well as down:  Magma retains it's existing ability to
scale an existing, large, multi-user repository _down_ to a single
user on a single laptop easily, without a single change to application
code.  This can be very useful for diagnosing production issues
without disturbing production.

42 one-click loads cleanly into 3.9, 3.10 and Pharo, and is supported
on those images.

For now, the Magma home page still resides at:

Great work Chris!

Pharo!

I have to say thank you very much Chris, for the effort that you and
Stuart have done. I am surprised that the release 42 already has support
for Pharo, I thought we would have to wait for the next version.

In this moment am downloading it and testing my app with it.

What a great news!

Cheers

Can I ask something?

You have a mcm for the complete magma tester set, r42final.

I'm loading magma with a script, using installer. The installer can load
mcm files and load each package on the mcm. But if I use the mcm for
r42final I get everything.
Could you also add mcm for the other sets, that is, the client set and
the server set of magma packages. Maybe something like:

r42-MagmaTester.
r42-MagmaServer.
r42-MagmaClient.

This will permit to load, using magma configurations, only the magma
packages needed.
Actually I use:

"Magma server"
Installer ss project: 'MagmaPharo';
  install: 'Ma exception handling';
  install: 'Ma base additions';
  install: 'Ma proxy support';
  install: 'Ma traverse object graphs';
  install: 'MaFixedWidthReport';
  install: 'Ma Statistics';
  install: 'Ma object serialization';
  install: 'Collections-BTree';
  install: 'Ma special collections';
  install: 'Ma client server';
  install: 'WriteBarrier';
  install: 'Magma client';
  install: 'Ma contextual search';
  install: 'Magma server'.

to get the magma server only. I compiled this list from the Magma Server
SAR file.

Thanks
