FYI, Spoon simulates on Mac/win32/Linux

Hi--

Just FYI, Spoon (VMMaker-dtl.237 plus support for proxies, method
reporting/imprinting and stale method removal) runs in the simulator on
MacOS, win32 and Linux, although "pluginClass" in
VMPluginCodeGenerator>>isTypePointerToStruct: is still undeclared.

Hi Craig. What do you exactly mean by support for proxies?
Can you elaborate?

Thanks in advance,

Mariano

Hey Craig!

It's great to see you back working in spoon!
I always loved the project!
(erm... sorry if you have been working all the time,
I was not very in touch with the Squeak community
for some years)

Excellent!

Thanks, fixed in VMMaker-dtl.238

Let me know if you need commit access to SqueakSource/VMMaker (I don't
see your user id listed, otherwise I'd just add you).

Hi Mariano--

> What do you exactly mean by support for proxies?

That's support for a special class, "Other". Each Other corresponds
to an object in another object memory, with a network stream connected
to that memory and an object ID. When a message is sent to an Other, the
VM turns it into a remote message to the original object, using a
mechanism similar to the creation of the doesNotUnderstand: message, in
the method lookup logic.

There are also a few other changes to ensure that all other
messages sent to Others are forwarded ("class", etc.). You had asked
about some of these when you were thinking about proxies, and I
mentioned my stuff at the time.

Thanks! Yes, it's good to be back. I spent most of 2009 and 2010 on
paid work.

Craig,

I added you as a developer. If you make updates to VMMaker (i.e.
the branch currently at VMMaker-dtl.238.mcz), please also update
the method VMMaker class>>versionString to increment the version
string (this is an ad-hoc identifier that helps to locate things
in the commit logs and that also becomes part of the installation
directory path for the Unix VM).

Thanks,
Dave

That's support for a special class, "Other". Each Other corresponds
to an object in another object memory, with a network stream connected

VM turns it into a remote message to the original object, using a

Ok. I understand. Do you do something in #lookupMethodInClass: that checks that the current class is Other. To do that you use objectMemory splObj: OtherClass
and you put Other in the special object array ?
Then if that's true, you fetch the instVar for network stream + ID (you assume the instVars offsets), and you forward the message to the original object?

There are also a few other changes to ensure that all other
messages sent to Others are forwarded ("class", etc.). You had asked
about some of these when you were thinking about proxies,

yep, I remember :)

and I
mentioned my stuff at the time.

uhhhh I don't remember :(
I will check.

Thanks Craig!

Exactly.

It's simpler than that; the VM just creates a message to the proxy
(in a manner similar to doesNotUnderstand:), using a special selector
which is also known from the special objects array. Then the proxy
forwards the message itself. The VM need not know about the network
stream or original object ID.
