Squeak VM update on OpenIndiana

 

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256


Hello,

Here's some news on Squeak on "OpenIndiana".

OpenIndiana is an illumos based operating system derived from OpenSolaris;

Current upgrades in the repository,

   http://pkg.openindiana.org/hipster/en/index.shtml

   squeak-4 : version 4.19.5
   squeak-5 : version 5.0.2945

There are packages for 'headless' (-nodisplay) operation and with GUI.

I've made up the version 5.0.2945 myself this corresponds roughly to
 VM Maker: VMMaker.oscog-eem.2945

This is because normally there is a 3 digit version number, but for
OpenSmalltalk VM I just use the number 5.0.2945.

Special thanks to everybody in the "Squeak" and "opensmalltalk-vm" team.

Thanks,
David Stes

Yes, both packages can be installed at the same time.

The packages are also delivered in both 32bit and 64bit
(but only Intel/AMD, not SPARC).

The packaging uses "mediators" which is something that can be used to have
multiple versions of some system installed.  

For example if I have squeak-4 installed (medatior version: 4),
and then install squeak-5 it changes version and implementation:

Changed mediators:
  mediator squeak:
           version: 4 (system default) -> 5 (system default)
    implementation: None -> cog-spur (system default)

So the mediator squeak is a property of the packages,
to have multiple "builds" or "variations" of the same package installed.

I am not building debug or profile VMs, but for example if a debug VM
would be built, then it could set the mediator to some value,
so that both the non-debug and the debug VM can be installed together.

Hi David,


Super cool.  I would like to see “ The squeak-4 package corresponds to the classic virtual machine (VM). The squeak-5 packages are OpenSmalltalk based virtual machines, where squeak-5 is the OpenSmalltalk stack VM and squeak-5c is the OpenSmalltalk cog VM.” extended with something like
“The relative performance of these virtual machines is approximately 1 to 1.5 to 15.”

Hi,

Related to additional information such as:

> "The relative performance of these virtual machines is approximately 1 to 1.5 to 15."

Under their github.com openindiana webpage they accept pull requests (PR's)
for the documentation so I suppose that you can create a PR ,
adding whatever information is considered appropriate.

Regards,
David Stes
