Hi. In anticipation of working on HydraVM, I am trying to test as close a configuration as possible to HydraVM without being hydra. That is, load the nearest ancestor VMMaker and C sources to hydra, and try to make a working VM. This should help ensure that there are no "normal" bugs once I switch to Hydra, only hydra bugs. So, I did that: Here is my setup:
- Fedora core 7 on x86 processor - Release 3.9 image/VM from squeak.org - Load FFI from SqueakMap - Load VMMaker-ar.70 from http://jabberwocky.croquetproject.org:8889/Homebase/ - Checkout http://squeakvm.org/svn/squeak/trunk revision 1796 (The nearest ancestor of HydraVM)
I pointed VMMaker at the platforms directory in the checkout, and told it to build source in platforms/unix/src. I selected all plugins to be external, but moved FilePlugin and SocketPlugin to be internal. Then I did
mkdir unixbuild cd unixbuild ../platforms/unix/config/configure make
make fails linking gnu-interp.o:
/bin/sh /home/matthewf/squeak/vm/hydravm-trunk-base/unixbuild/libtool --mode=link gcc -g -O2 -fomit-frame-pointer -DLSB_FIRST=1 -export-dynamic -R/usr/local/lib -o squeak vm/vm.a FilePlugin/FilePlugin.a SocketPlugin/SocketPlugin.a disabledPlugins.o version.o -lutil -ldl -lm -lnsl vm/vm.a gcc -g -O2 -fomit-frame-pointer -DLSB_FIRST=1 -o squeak disabledPlugins.o version.o -Wl,--export-dynamic vm/vm.a FilePlugin/FilePlugin.a SocketPlugin/SocketPlugin.a -lutil -ldl -lm -lnsl vm/vm.a -Wl,--rpath -Wl,/usr/local/lib vm/vm.a(gnu-interp.o): In function `primitiveGetWindowLabel': /home/matthewf/squeak/vm/hydravm-trunk-base/unixbuild/vm/gnu-interp.c:15141: undefined reference to `ioGetWindowLabel' vm/vm.a(gnu-interp.o): In function `primitiveSetWindowLabel': /home/matthewf/squeak/vm/hydravm-trunk-base/unixbuild/vm/gnu-interp.c:18770: undefined reference to `ioSetWindowLabelOfSize' collect2: ld returned 1 exit status
Building this VM worked when using the latest VMMaker from SqueakMap (VMMaker-tpr.58), everything else the same. Is there something else I need to do in order to build using the Croquet VMMaker? I want to use it specifically, since the Hydra VMMaker is derived from it.

These are support functions that are currently not implemented in the Unix/Mac VMs (we use them to get/set the main window title directly). Here is how to stub them (best done in sqUnixMain.c):
char* ioGetWindowLabel(void) {return "";} sqInt ioSetWindowLabelOfSize(void* lbl, sqInt size) {return 0;}
This should do the trick.
Cheers, - Andreas

Actually, I need to implement these for X11 anyway. Expect this to soon be supported in the OLPC branch. Unless someone beats me to it of course :)

Bert,
Here is a snapshot of a partially implemented HostWindowPlugin for X11. I have not looked at this in quite a while, but when I last worked on it a number of things were functional (including ioSetTitleOfWindow(), for whatever that may be worth).
Some of the support code is crudely hacked out of Ian's original work, and I would anticipate some effort to make this right. In particular, it was not clear to me how the X event dispatching should ultimately work, and whether the host windows should behave analogously to Squeak projects or if they were intended to be more like passive display surfaces.
I could probably be motivated to pick this up again and/or to help you with it, but in any case feel free to use this in any way you like. MIT license of course, and the plagiarized parts should be MIT because I stole them all from Ian ;)

Oh dear, I thought it was "My Implementation Taken" which is why I felt at liberty to engage in outright plagiarism. If the license permits only the plunder of ideas, I may have inadvertently exceeded its boundaries. Next time I'll consult a lawyer before taking unnecessary risks ;)

Hi Ian, folks -
I implemented the scaffolding for the HostWindowPlugin in the Unix VM. It's a bit more complicated than other platforms because we support multiple UI frameworks on Unix. I added the functions to the SqDisplay dispatch structure, increasing its minor version to 2. The functions are stubbed out in all display modules. In the X11 display module I only implemented the one function we need right now, namely setting the main window's title.
Since this is primarily for Etoys I attached my patches to this ticket:
http://tracker.squeakland.org/browse/SQ-71
There is a tiny changeset allowing for
DisplayScreen hostWindowTitle: 'Hello World!'
which I tested on a Mac working fine, and now on X11 too, using windowIndex 1 for the main window.
The patches are attached as a diff, as well as a tarball of all the changed files. Ian: Please integrate as soon as you find time (there is a tiny other patch in there, making -xshm not abort if xshm support is missing).
David - sorry for not using your HostWindowPlugin code, but it was X11 only which is not the Right Way to do it. It should be reasonably simple for someone to adapt your code to the infrastructure I provided now (including generating events for secondary windows). I myself will not implement multi-window support any time soon.
Andreas - reading the message below again I still don't know where ioGetWindowLabel/ioSetWindowLabel comes from. Which platforms support this, where is the primitive code, and how is it exposed in the image?
Thinking about it it might have been simpler to use these functions. Is it okay to abuse the HostWindowPlugin for this? One reason I did it was that we'll soon need the window-size setting feature, too. And at least on the Mac prim #92 is buggy, whereas the HostWindow equivalent works fine. In any case having full HostWindow support would be useful, me thinks ;)

Good, I was pretty well stalled in my attempt to do HostWindowPlugin anyway.

I know what you mean ;)

Indeed it does. It made the VM compile successfully, although I havn't tested it yet. Thank you.
