Nice! I didn't know those worked already.

It would be nice if some kaffe hacker could explain the relation between these versions.

That does make sense. In the GNU Classpath gtk-peer awt implementation a lot of work has been done to support "lightweight" components (like Free Swing). This is less developed in the old style kaffe xlib-awt framework. But in a couple of places we seem to forgot to check that old-style "heavyweight" (aka plain awt components) still got the events if the lightweights didn't handle them. > Trying to report the presumatley ppc related bug I have now learned: > d) There seems to be generic event bugs in classpath for kaffe. Yes, as far as I can see they are not platform specific. The mouse events issue seems to be solved now in a generic way.

Or we can try to get kaffe to make a new release! :) Including at least the patch from PR26641. > ii) Retest my two testcases for Mandriva. Thanks for all the testing. It (and the testcases) are really helpful.

Correction I was using: 0:1.1.7-0.rc1.3mdk, See history section of http://cvs.mandriva.com/cgi-bin/cvsweb.cgi/contrib-SPECS/kaffe/kaffe.spec which probably is 1.1.7rc1. > Next I wanted this on powerpc and tried > > b) kaffe-1.1.7rc1 (my Debian backport on ppc): > The go applet did display fine, but did not receive mouse or key events. Thinking about this: It might have been: No mouse events only, I cannot say for sure. At least the testcase is likely to be different from the frame receiving the events. > ii) Retest my two testcases for Mandriva. contrib kaffe package 0:1.1.7-0.rc1.3mdk: The TestMouse works, the TestKeyEvents does not. So TestKeyEvents did never work in the kaffe versions I have tested. ___ kaffe mailing list kaffe@kaffe.org http://kaffe.org/cgi-bin/mailman/listinfo/kaffe

I'll use this as an opportunity to drop a note to the list on what I plan to be hacking on in the next few months. If you read my Advogato diary, you might have read that after 6 years in California, I'm quitting my job and I'm moving back home to Vancouver, British Columbia, Canada. I should be finished with the move in mid-April. I've been saving, so I'm planning to take at least 6 months to just work on my own projects and do a little freelance work on the side to cover expenses. The #1 project I want to do is build a full blown regression testing setup for Kaffe. It will be useable by other projects as well. But Kaffe is going to be the focus and the original guinea pig. Really, I started working on this particular problem 5 years ago when I was still at Transvirtual. I was developing a testrig for testing Kaffe for in-house use, but it wasn't very well developed by the time the company shut down. About 3 years ago, I also put some scripts together for Kaffe, but there was too half-baked and I never deployed it publicly because I just didn't have enough time to fully develop it. (I think I described some of my ideas to Dalibor at FOSDEM two years ago). The last couple of years, I've done a fair amount of similar work building in-house systems for Digeo. So it's sort of unfinished business for me... The difference this time is that I've got time, money and server space - so I think I'll be able to pull it off. I've also got some ARM, MIPS, SuperH, and PowerPC hardware I've collected over the years that I'd like to put online and dedicate to Kaffe testing. I'm going to set up a wiki in few weeks with all my ideas - it would be a pretty long email if I list them all here. To the end users, the system will look like an ordinary website where they can log in, setup tests, and run them. I'll be able to provision Xen sessions on the fly for testing things like various x86 Linux distributions, *BSD, Solaris, etc. I'm aiming for a "folksonomy" model of doing distributed testing. There will be data collection and querying facilities -- I've been playing around a lot with RDF, and I think I'm going to try to use it. Think of it as a replacement for SQL - but with easier import/export and Web 2.0 "mashup" possibilities. It will be really, really easy to build web pages that query the RDF database, and generate reports on how "healthy" Kaffe is for a particular target. It's quite an ambitious plan -- but I'm going to start small. The first thing I'm going to try to nail is getting decent regression testing for x86, then ARM and MIPS, because those are the platforms I want to use. :-) Oh, and everything will be released as free software too, in case you had any doubts...
