Otherwise I would have to rewrite it from scratch, because parrot does not accept the GPL or LGPL alone.

Re: [kaffe] Support for jit3 on arm/netbsd
Excellent! I think this is the first commit in 5 months since Dalibor did the last release. I notice that the CVS email script seems to be broken -- and I still need to fix Bugzilla. When I get some time, I'll try to setup gxemul so I can try it out! Cheers, - Jim Kiyo Inaba wrote: Hi, Yesterday, I've committed 'partial port' of kaffe to arm/netbsd/jit3. This port is different from arm/linux port, because NetBSD port does not use (1) any floating point instructions. The current linux port uses slightly old FPA instructions (with hardware support or software emulation resides in the OS), even though there are very few arm hardwares shipped with real FPAs (2). The reasons I said this as a 'partial port' are 1) I just make float support, and not double. This is OK to execute the most basic 'HelloWorldApp.java' test in kaffe's regression, but of course double related tests all fail. 2) Since the latest snap needs extra libraries and installing all of them take long time (3), I just use relatively old snap (precisely speaking, 2007/05/10 version) as a base for this modification. 3) I did not ifdef'ed all unneeded functions in 'jit3-arm.def'. For example, the function 'fmove_RxR' is not needed when 'HAVE_NO_FLOATING_POINT' macro is defined. 4) I still set _GR_ (4) as 0 in 'jit.h' file for arm :- Currently only two functions (fspill_Rxx and freload_Rxx) which handle float values (5) are activated. I tested this modifications on 'gxemul' emulator available from http://gavare.se/gxemul/ with NetBSD 4.0 for cats and more than 100 regression tests in kaffe can be passed. I may continue improving this port (6) in some day, but my 'summer of code' season is over, and may take long time... Kiyo 1) As usual, NetBSD does things right, linux does things #. (Fill in the sharps with your favorite term, please) 2) You can read some story for arm's history of flaoting point support hardware in http://wiki.debian.org/ArmEabiPort. And you may find why kaffe still has '__XSCALE__' define in several places. (In Xscale processor the FPA instruction overlaps with their own extension, and the linux port on Xscale should be compiled with soft-float) 3) Especially, atomic support. To install 'glib', I first install several other gtk libraries... 4) The _GR_ macro is used to set properties of arm's registers. Since I set _GR_ to 0, which means (in jit3) there are no global registers available right now. Of course, this is a major reason why jit3 is slower than jit in arm port. 5) Of course there are no floating point registers (even in emulation) on arm/NetBSD, the emitted code by these functions are changed (ifdef'ed). I select to modify these two functions but the other idea is to keep these two functions same, but change the property of values from 'float' to 'int' (and 'double' to 'long') when register allocation is invoked. The latter may make my modifications to be architecture independent. 6) As some may remember, ARM is not my favorite architecture. I attack this port because I want to make m68k (well, Coldfire, these days?) or SuperH work for jit3 without FPU. So these may have higher priorities than fixing arm port. ___ kaffe mailing list kaffe@kaffe.org http://kaffe.org/cgi-bin/mailman/listinfo/kaffe ___ kaffe mailing list kaffe@kaffe.org http://kaffe.org/cgi-bin/mailman/listinfo/kaffe

Hi everybody, Sorry for the downtime on the website and mailing list for the past few days. I was seeing some strange activity on the server on Friday. I was afraid I had been hacked/cracked, as the server was still running a really old version of Debian (Woody, released in 2002). It turned out to be a false alarm, but I decided to upgrade the server anyways, knowing it would likely break a few things.

[kaffe] Future directions for Kaffe
Hi everybody, It's been a quiet month on the mailing list so far. That's partly my fault, I think, since the mailing list was broken for some time. It looks like the last CVS commit was 5 weeks ago. I see Dalibor went to FOSDEM, and did some talking about Kaffe there. So I'm assuming that the project isn't dead, it's just somewhat dormant. It's been somewhat dead/dormant throughout much of it's history, but it's still here, isn't it? :-) And clearly, all the free Java runtimes and Classpath are in a state of transition, as we wait for Sun to release the rest of OpenJDK. I'd like to liven up the list a bit, and maybe start a bit of discussion on where Kaffe should go next. Here are some things I'd like to talk about: * I definitely need to do some work on upgrading the server, and fixing up the website. Currently it's running a really old version of Debian, so it needs to be upgraded. I'm just scared of all the breakage that will happen. I'm slowly building up my hosting capabilities, but it's just a hobby, and I have real life things going on, so I move at a glacial pace. If anybody wants to help out with any of that, I'd really appreciate it. I happy to keep hosting it indefinitely. * I think a wiki running on top of Kaffe would be really nice. :-) * On the other hand, there are establishing free software hosting platforms like Sourceforge, Savannah, Google Code, etc. that might work better than just running everything on our own server. Our current infrastructure is pretty much still using technology from the 1990s. We don't even have a blog or a wiki, or any continuous integration or distributed version control. I'm open to migrating things if that's what people would prefer. * Technically speaking, I'm still the project leader, by virtue of rescuing it from the ashes of Transvirtual. But Dalibor is really the guy who has been doing most of the work. I'm not really doing much with Kaffe personally, so if anybody else wants to step up and be a real project leader, feel free to volunteer. I'm still happy to keep hosting the project and helping out with the releases. * Speaking of releases, we really should do another release sometime. * I'm embarrassed to admit that I don't even have Kaffe running on my new MacBook under OS X. I got it to compile, but I couldn't get it to even run Hello World. If I spent some time on it, I imagine I could figure it out. I just haven't spent the time. I hope it still runs OK on Linux, but I haven't tried that recently either. * I also haven't been responding to emails asking me for help getting Kaffe to run. I'd like to, but since I don't even have it working for myself, I'm not really in a position to help out. I get so much spam nowadays that I hardly even use email anymore. I notice that most requests for help to the mailing list are going unanswered as well. * I'm still interested in playing with Java virtualization, and I'm very excited about OpenJDK coming out. JRuby looks really interesting to me. For my own projects, I'm guessing I'd probably use OpenJDK in preference to Kaffe in the future, since it's likely to be a lot less effort to get it working the way I want it to. * That said, I think Kaffe has been a seminal project in terms of getting free Java off the ground, and I'd hate to see it die. A lot of interesting projects have used Kaffe as a starting point. * I imagine that in the future, people will most likely look to OpenJDK as a starting point to add their enhancements. Is there still a role for Kaffe to play here? * I think Kaffe probably is still the simplest full JVM implementation that isn't just an interpreter. It's been used for all manner of exotic porting projects that might just be too hard to do using something like OpenJDK or gcj. * Kaffe is licensed under the GPLv2. So is OpenJDK. But Kaffe doesn't require copyright assignment, and we're pretty open. Sun doesn't have to vette the code going into Kaffe. That suggests that perhaps we could merge in large parts of OpenJDK, and provide a place for people to do really experimental stuff that Sun isn't going to permit in their version. Is this something we should consider? * In other words, should we go big? And merge in as much stuff as possible. That could be problematic, since Kaffe is already pretty huge. Maybe we could adopt more of a distribution approach, and break things into a bunch of modules that are all developed to work together? * Or maybe we should try to stay small? And just try to be an easily hackable, simple virtual machine with a crude compiler framework, and nothing else? That would involve jettisoning or spinning out a lot of the integration work that's been done over the last few years, I think. * I think we've been trending towards the go big direction for some time, with all the Classpath merging and other projects, and the core has been somewhat neglected. It's been really good to support Classpath this way, and

Re: [kaffe] ARM and kaffe
Kevin D. Kissell wrote: Oh well, I am working through similar issue. To make Kaffe workiing somehow set into configuration '--with-engine=interp'. It'll solve your problem but makes your kaffe working terrible slowly. The real problem is somewhere into JIT3 module and it is a memory management issue. I've sent a few letters to the guy whom ported it but no answer what so ever. I tried already but no luck. I had kaffe JIT3 95% working with MIPS after hacking up the 1.0.7 source base back in 2002. It failed 6-8 regression tests, but ran well enough to handle the embedded CaffeineMark benchmarks. Then 1.1.0 came out, which was a huge step backwards for non-x86 JIT3, and after beating my head against it for a week or two, I gave up. I was able to determine that incomplete internal data structures containing null pointers were being used, but couldn't figure out why, and whoever maintained JIT3 apparently couldn't care less about non-PC platforms. 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...

[kaffe] GPLv3
Ok, Licensing threads bug me, but the discussion is going to happen anyways. The first draft of the GPLv3 is out... http://gplv3.fsf.org/ What do people think? I only glanced at it, but there are some things I like. I think it really helps clear up the FUD (fear-uncertainty-doubt) that claims that a GPL'd virtual machine like Kaffe would only be allowed to run GPL'd Java applications. Here's the specific language from the exception clause: As a special exception, the Complete Corresponding Source Code need not include a particular subunit if (a) the identical subunit is normally included as an adjunct in the distribution of either a major essential component (kernel, window system, and so on) of the operating system on which the executable runs or a compiler used to produce the executable or an object code interpreter used to run it, and (b) the subunit (aside from possible incidental extensions) serves only to enable use of the work with that system component or compiler or interpreter, or to implement a widely used or standard interface, the implementation of which requires no patent license not already generally available for software under this License. I understand that the license is supposed to be anti-DRM as well. I imagine this where the real battle is going to be. The legal language which prevents the code from being used in systems that use DRM is pretty broad, I think. I can see people who want to use GPLv3 stuff in closed systems are going to have a lot of room to play games. I can see a lot of legal activity arising out of this, which is something that the GPLv2 hasn't really been afflicted with. Again, I didn't read it very carefully. There is also some language about patents. Kaffe is currently under the GPLv2. As I understand it, we can opt to upgrade our license to GPLv3. Or we could stick with GPLv2. If we upgrade to GPLv3, old versions will still be available to people that can't handle the new license terms. If we stick with GPLv2, other people could take that, and apply the GPLv3 license to it. I wonder what the Debian legal folks think about the new license? At this point, I think I'm leaning towards using GPLv3, because it helps de-FUD Kaffe a bit. On the other hand, I can imagine that the GPLv3 will create big headaches for companies like my present employer (whom I'm still employed with until mid-March). They make a settop box for cable companies, which completely locks down the content on the box. If the anti-DRM measures are effective, and things like the Linux kernel, glibc, coreutils, busybox, etc. go GPLv3, they might have to get their OS code somewhere else. Most consumer electronics companies building embedded products are in the same boat, I imagine. Cheers, - Jim ___ kaffe mailing list kaffe@kaffe.org http://kaffe.org/cgi-bin/mailman/listinfo/kaffe

Remember, companies like SCO will sue people even if they have no legal basis for a case. I didn't even mention the messy situation with software patents, particularly in the U.S., and possibly Europe, soon... Who knows what patents companies like Sun, IBM, Microsoft and others are holding that might apply to our implementation?

After I modify kaffe's source code for commercial distribution, I want to use for kaffe virtual machine in digital television settop box. And then, Have I a duty to give money? Where? Good to hear someone is trying to deploy the usability of kaffe :-) Since kaffe is licensed by GNU General Public License or GPL, you need not to pay money at all. The main obligation for you is if you modify some part of kaffe, you also have to make this modified portion open. See more detail in http://www.opensource.org/licenses/index.php I hate to add FUD (fear, uncertainty, doubt) to our own project, but I think some history of the licensing of the project might be illustrative. It's all a bit unclean, unfortunately. We should right a FAQ on this... In the early days, Kaffe was released by Tim Wilkinson under a BSD style license. When he started a company (Transvirtual) to commercialize the technology, they started doing newer releases under the GPL, which was supposed to discourage people from using it in commercial products, so they could sell their proprietary version. That business model didn't actually work very well, and Transvirtual eventually closed down. The GPL license is somewhat undefined in terms of how it interacts with other code. It's not a license I would have chosen for a virtual machine. Some people say if you run an application on top of the VM, you would have to make that application GPL-licensed too. Some people say that's nonsense (I tend to agree with that viewpoint). To my knowledge, I'm not aware of any cases where somebody has been sued for running non-GPL code on a GPL'd virtual machine. It's not a common scenario. I think Transvirtual actually came to regret re-releasing the VM under the GPL, since they saw that people were actually using the GPL'd version for commercial developments, and were not coming to them for the proprietary version. The Kaffe project never demanded copyright assignment, so the intellectual property rights for the various bits in the virtual machine still reside with the authors of those parts (similar to how the Linux kernel is owned). This means that the parts of the virtual machine contributed by Transvirtual are still owned by whoever has acquired the assets of Transvirtual. The company at twincom.net looks like they may have acquired the assets, but I don't know what sort of legal agreements they have signed. Also, other contributors to Kaffe, eg. the people on this mailing list, own the parts they have contributed. Personally, I would never sue anybody over using Kaffe for any purpose, and I'm sure most of the other contributors feel the same way. I would like to see users comply with the spirit of the GPL, and contribute their modifications to the virtual machine back to the project. However, I cannot 100% guarantee that the whoever holds or buys the rights to the old Transvirtual stuff might not someday demand compliance with their interpretation of the GPL, and threaten to sue if that does not happen. I suspect that this scenario is somewhat unlikely, since it would cost a lot of money to sue, the legal case probably isn't very good, and the amount of damages that they could get would probably be minimal. I suspect the current owners of the old Transvirtual IP are aware that they own it, but they also realize that it would be extremely difficult to extract any value out of it using this method. So, if you absolutely can't take any legal risks, you might be better off just prototyping with Kaffe, and then choosing another Classpath-based virtual machine to actually put in your product. If somebody was motivated, we could attempt to track down all the IP holders that have contributed to Kaffe, and attempt to relicense the project or get copyright assignment. That may be difficult though, especially since some of them have died. It would probably just be easier to direct efforts to some of the other virtual machine projects out there with cleaner licensing, especially since they now share so much with Kaffe (eg. the Classpath libraries). That said, I personally don't think that Kaffe's somewhat unclear licensing situation is much of an obstacle for most uses, so I don't see any reason not to keep the project going.

It has been tested, but not as thoroughly as a production release would be. It contains major improvements over 1.1.4, which was released one year ago. I anticipate that most people will have less trouble with this release, and more fun. Even though this is not a production release, it contains a large number of improvements over 1.0.7, which was released over two years ago. Don't use 1.0.7, it's ancient! We will release a new production release very soon. Here are some highlights of new things done since the last development release: * Resynced with latest GNU Classpath. * Added GNU EmbbededWindow extension from GNU Classpath. * gcjwebplugin is known to work with the extension. * Improved AWT implementations. * GNU Classpath's implementation of AWT/Swing has been merged. * New Nano-X AWT backend. * Xlib AWT backend supports xi18n wide-character display. * Dynamic switch among existing AWT implementations via command line options. * Better stack pointer / stack size handling. * JNI direct invocation fixes. * Verifier moved to its own directory. * JNI upgrades to 1.2 * New experimental Boehm-Weiser garbage collector. * Merged in JIT3 for powerpc from JanosVM. * Implemented weak references in the VM. * KJC temporarily replaced by jikes. * DNSJava, Jessie, JZLib and gjdoc merged in. * Added some internationalization support to kaffe's executable (fr, zh_TW). * Many compiler warning fixes. * Tested in Ch environment. * Fixes for NetBSD, OpenBSD, FreeBSD, Darwin. * New ports to FreeBSD on x86-64, Darwin on x86 and HP-UX on ia64. * Some successes: Resin2, JSDL, SwingWT, gcjwebplugin, ME4SE, MicroEmulator, VNCj, LwVCL, DirectFB kawt, Eclipse 3.0.1, 3.1M6.

Re: [kaffe] GNU Classpath and Kaffe
I haven't posted to the list in quite some while, so I guess I should chip in so people know I'm still here. Y'all are reading my blog on Planet Classpath, right? :-) Michael Franz wrote: Hi, My understanding is that Kaffe is going to start using the GNU classpath instead of it's own implemenation of the Java libraries. What is preventing us from using them today?Is there a TODO list that people are working that will get us to this point? Is there a timeline for this? Dalibor has been working feverishly merging in all the Classpath stuff. Eventually, we'll be able to scrap the old Kaffe class libraries completely, and just use Classpath. There are obstacles of course, because Kaffe developed it's own VM interface, which predated Classpath VM interface - that all needs to be reworked, without introducing too many regressions. It looks like we're gradually getting there, bit by bit. I haven't done any diffing to see what the status of the migration is. I'm sure Dalibor can speak to this. I see Kaffe as a staging area for the Classpath project. Most class library development happens there, but we're a good place to test things out before pushing it to the mothership. Another question, when is Kaffe 1.1.5 coming out? When it's ready (TM) This is my area - I've been moving a bit slow unfortunately. For 1.1.5, my stated goal is to not do a time-based release, but to have a testsuite, and release it when it passes the testsuite. The 1.1.5 release will still be a development release, so we don't have to make the testsuite too hard to pass. I don't want to go back to doing time-based CVS-snapshot style releases, since we get way to many regressions without some rigorous testing. I also was finding that it would take me several days of work just to manually hammer out all the little packaging bugs before I could do the release. That's just no fun -- I'm just doing this as a volunteer project. I would have preferred to have had a testsuite and a release out months ago. However, I've been preoccupied with setting up a new server for the project. Like everybody else, I'm doing this project in my spare time, which is hard to come by, so things progress slowly. The server is going to be a really nice thing to have for doing the releases, as I'll be able to centralize all the testing and release systems on it. I've almost got the new server ready to put into production (but not ready to replace the current server yet). One of the first things I'm planning to put on it is a wiki for test/release planning.

[kaffe] Server downtime
Hi, I apologize for the server downtime - it's back up now after I drove to the colo. It appears it was a system administration problem - I think all the nameservers in /etc/resolv.conf had long since gone away. I also had a strange issue which was preventing console logins. I reinstalled a few packages, and the problem seems to have gone away. I was somewhat concerned that the server may have been compromised, but I couldn't find any evidence of that (eg. testing with chkrootkit). It's probably worth keeping an eye out anyways in case I missed something. The good news out of all of this is that I had an extra 512MB DDR SDRAM that I stuck in the server, so it now should be more responsive. I'm planning on upgrading the server shortly so I can use it for some additional projects, for example, sharing some resources with the Classpath developers.

[kaffe] Release status...
Hi, I announced that I had made a branch for the 1.1.5 release almost a month ago, but I haven't made the final release yet. :-( So I thought I'd drop a note to the list on what's taking me so darned long to do it... Part of it is due to the usual excuses (work, real life, etc.) and my own procrastinating. But part of the reason is due to the fact that I want to make some improvements to the process. There are several steps to making the release: a) Reviewing the changes and summarizing them for the release announcement. b) Building it in several places and actually trying to use it to run some software. That's been the extent of my testing for the development releases. c) Fixing any obvious configure issues. There are so many ways to configure Kaffe, I always seem to run into issues nobody else has. d) Fixing any make dist type problems that show up. In the final steps of making the release. Typically, I need to cycle through the build multiple times, as documented here: http://www.kaffe.org/cgi-bin/viewcvs.cgi/kaffe-project-services/release-process/HOW-TO-MAKE-A-RELEASE?rev=1.1content-type=text/vnd.viewcvs-markup Naturally, this would be less work if I did this incrementally as development progressed. But I always end up doing this at the end. With the previous releases, it took me a good 8-12 hours to do all the steps. That's just too long, and it's not fun work. This time around, the amount of work involved has increased a bit, because of the longer interval since the previous release (partly due to my procrastinating). Also, the fact that so much new good stuff has gone into it means that I encountered a lot of regressions all over the place, to the point I wasn't really happy with the final result. (I think the code in CVS right now is quite a bit better than the state it was in when I made the 1.1.5 branch a month ago) When I encounter Kaffe-related problems on one of my various machines around the house or the office, then I've got to make a decision. I can either take some time to try to fix/debug/understand the problem (perhaps asking the list for help), or I can skip past the problem so I can get the release out sooner. Naturally, I don't like skipping past problems -- I'd rather fix them, but there are really are a near-infinite number of bugs to fix, so when it's late in the release cycle, it's usually better to skip past them and just get the release out. There's a trade-off though -- if I skip past too many bugs, then all those bugs are going to go into the release, which isn't good. Anyways, on to the process improvement part of the tale: Ultimately, I want to automate the whole release process. When checkins get made, they should be automatically tested for regressions on a whole variety of different platforms and in different configurations. The code should only be considered release-worthy when it passes all the testing we throw at it. The release process should be as simple as selecting a particular build that passed all the testing. This way, we can certify that a particular build works and was tested on all the various platforms and configurations we support. The distinction between a production release (which is one of my goals for this year) and a development release should primarily be that the production release will have passed a lot more testing. If we had such a system in place, then the testing and fixing grunt work that gets left until release time (and lumped onto me) would instead be done incrementally as development occurs, and shared by everyone. I actually started coding up a custom regression testing and reporting system last year, and I probably got it 50% done. I think I could probably get it partially deployed with about a week's worth of work. Does anybody have any objections to me holding off on the 1.1.5 release until I get the regression testing system deployed on the server? Initially, I'll just set up some testing environments on some of the servers I have access too. After I get something working, I'll try to document as much as possible so other people can help out with the testing. If I could get the regression testing system set up to do most of the release testing, that would really make the release process simply (almost automatic). It would be a lot more fun too. Sorry for keeping everybody in suspense for so long... Cheers, - Jim ___ kaffe mailing list [EMAIL PROTECTED] http://kaffe.org/cgi-bin/mailman/listinfo/kaffe
[kaffe] Release_1_1_5_Branch created
Hi, I've made a release branch for 1.1.5, tagged Release_1_1_5_Branch. Since the branch has been made, feel free to check any new stuff into the HEAD of cvs. I was a little short on time today, so I didn't have time to finish off the release. Sorry about that. In my limited testing here, I've encountered a few problems. For example, building it with on Red Hat 8.0 on my laptop, it has runaway memory usage when it tries to compile the class libraries. The same code compiles fine on my Debian unstable machine, so I should be able to chase down the problem with some more investigation. Hopefully, I can get the tarball out in the next few days. That should give me some time to do some additional testing as well. This release is not meant to be much more than a development snapshot, but I'd like to minimize the amount of regression people see if they're moving up from 1.1.4. To make my job easier, please try to refrain from checking in patches on the Release_1_1_5_Branch - just check them into the HEAD, and I can merge over any patches I think are critical for the release.

[kaffe] Feature freeze this weekend and upcoming release
Hi, Just a friendly reminder - I'd like to try to branch and hopefully release 1.1.5 next Sunday. So today, as planned, I'd like to call for a feature freeze -- so please hold off on checking in anything that's going to require additional testing until after the release branch has been made next weekend. I'd also like to ask for people to try building and testing the latest code on as many platforms and in as many configurations as possible over the next week. Cheers, - Jim ___ kaffe mailing list [EMAIL PROTECTED] http://kaffe.org/cgi-bin/mailman/listinfo/kaffe
[kaffe] Next development release planning - 1.1.5
Hi, It's been about 2 months since the last development release - I'd like to do another one. I know some people would prefer to see a goal-based development release schedule, as opposed to just releasing every two months. I'm somewhat biased against that, though, just because it's more work for me, and I think the schedule would slip. If we did that, I'd have to switch to a mode where we actually planned and scheduled what was going in, and try to drive development to meet deadline. That might be a good idea, but it's more work, and it's hard to push free software volunteers to meet hard deadlines. Maybe we can do a little bit more of that while still doing timed releases? That might be possible if somebody wants to step forward and volunteer to do some project management. We need to do a production release sometime, the sooner the better, in my opinion. I haven't formulated a concrete plan for that one yet, though. So here's my proposal: How about if we do a feature freeze in three weeks, on Sunday, April 25th, to be followed by an actual release on Sunday, May 2nd? (I'd really like to do it a week earlier, but my parents are coming for a visit) Cheers, - Jim ___ kaffe mailing list [EMAIL PROTECTED] http://kaffe.org/cgi-bin/mailman/listinfo/kaffe
[kaffe] Kaffe 1.1.4 Development Release available for download
I've made the 1.1.4 release of Kaffe available for download at: ftp://ftp.kaffe.org/pub/kaffe/v1.1.x-development/kaffe-1.1.4.tar.gz http://www.kaffe.org/ftp/pub/kaffe/v1.1.x-development/kaffe-1.1.4.tar.gz This is the next in the 1.1.x series of development releases. Although not as fully tested as the current production 1.0.7 release, most users will find it to be much more functional and complete. We are planning to update the production release later this year. As this is a development release, it is essentially a snapshot of what's happening in CVS, with limited testing. Here are some highlights of new things done since the last development release: * Support for security policy files * AttachCurrentThread jni function for posix threads * Bug fixes: * jar tool and jar file fixes * URL context handling * EUC-JP support rewritten to use libiconv * HTTP fixes * MulticastSocket * DNSJava binding * ARM jit * ServerSocket.bind * java.math.BigDecimal - fix rounding operations * JNI fixes * FTP handler from GNU Inetlib * SHA1PRNG randomness fixes (can use /dev/urandom if available) * java.security.SecureClassLoader fix * GNU Classpath merges and updates: * Object serialization * almost all of java.io from Classpath * java.nio, java.net * java.util, java.util.regex * java.math, javax.naming * java.text, java.beans * java.net.protocol.file.Handler * java.util.Random * java.awt.GridBadLayout * java.awt.geom * javax.swing.event.EventListenerList * javax.swing.text.AttributeSet * Updated sound code from Tritonus.org * Updated javax.net.ssl/javax.security code from Jessie * kjc bug fixes: * .this expressions * extra generated clinit methods * static initializers fixed. Circular definitions of fields are now supported. * Build fixes: * m68k atomic compare and exchange * m68k-netbsd * ALSA 1.0 * mipsel-linux / jit3 * Cygwin * FreeBSD networking * parisc and HP-UX * New DocBook documentation: * Porting Kaffe to a new platform * Support for debugging using cgdb * Build system: * updated to automake 1.8.2, autoconf 1.59 and libtool 1.5.2 * moved automake scripts and m4 files out of top directory * new regression tests for kjc * Code cleanup: * some macros (sysdepCallMethod, CALL_KAFFE_EXCEPTION) converted to inline functions * moved vm specific part of java.lang.Thread into threadData * More compiler warnings fixes * Some successes: JSPWiki, Babylon chat server (without graphics), Ant 1.6.0. Some regression tests do fail in this release, and many of the ports are still broken. Again, thanks to all of our developers, testers, and users! Also, if you happen to be in Brussels this weekend for FOSDEM, I'll be there and so will a bunch of other free Java hackers.

Overall, I'm very impressed with the continued progress. The speed at which Kaffe is improving is incredible. There will probably be one more development release in about two months, and we'll probably put out a heavily tested production release (1.2.0) in early 2004.

The second time you hit it, the JSP has already been compiled and linked in (it's just Java classes), so it's very quick. There are ways to precompile JSP pages and preload them, if you want to avoid the first time penalty. You can also configure Tomcat to use Jikes as a JSP compiler.

It's definitely something I want to see happen, I'll probably even do it myself someday, since I actually care about Windows somewhat (I occasionally play games on it, and my family uses it).

You have 1 process hidden for readdir command You have 1 process hidden for ps command Warning: Possible LKM Trojan installed But that's a common false positive due to the way it does the test (due to a mismatch between Debian's 'ps' command output and /proc). Just to be sure, I removed kernel module support from the kernel, and it still does it. My web server at home had some false positives as well - yay. I also upgraded to kernel 2.4.23 (because of the latest ptrace bug that was used to compromise Debian), and updated rsync (which was used to compromise Gentoo). We don't have a lot of user accounts on the server, and I usually upgrade packages within hours of reading the Debian security advisories, so I think we've been lucky so far. I think with all of these high-profile comprosises lately, I'm going to take some measures to tighten up security on the server even more. There's a few things I've been wanting to experiment with, like moving some services out of the main server environment to individual user-mode Linux virtual machines, and even running some of the services on Kaffe itself. And I'll probably look at ways of tightening up password security, etc. This should only affect the few developers that have accounts on the server - it probably affects me the most. For the rest of the users, I strongly encourage you to use the GPG signature files that I make for every release to verify that the released files have indeed been signed by my private GPG key.

I think that would be a safe one to go with. I'm encouraged that there also seems to be a Maven plugin for it: http://maven-plugins.sf.net/maven-doxygen-plugin/ So, theoretically, we can plug it into our Maven-based documentation generation system. Again, I expect that we may have to modify a few Maven plugins and put them in kaffe-extras to get the exact output we want for the published tarballs and the website. I took a brief look at gjdoc, but there is only the cvs code. What will be the feature set of gjdoc? I'll have to let someone else answer that, as I haven't played with it yet. I'm hoping it's got the basic Javadoc features so that we use it as our Javadoc, and use it with tools such as Ant and Maven. I think some IDEs parse the generated HTML documentation, so that might be one tricky area for compatibility to watch out for. One more thing I forgot to mention in the proposal - some ideas I have for the documentation development process: 1) I want to keep as much development on the mailing list as possible. 2) I'm thinking of moving the website over to Tomcat - so we can add various webapps to it to do some interesting things. 3) I've got a half-done regression testing system I would like to deploy on the website. I'd like to hook that into the documentation generation system somehow -- primarily so that the documentation can say things like Application XYZ version 1.2.3 passed basic regression tests on Platform XX with Kaffe x.y.z. If we can say things like that, then we'll get users for our future production releases. 4) Even though I want all the discussion to happen on-list, I'm starting to think that a Wiki might be useful. It could be used to store various bits of quickly mutating information, or for editing drafts of half-baked documentation before we commit it into CVS. Opinions?

I'd actually propose a faster release schedule: once a month after 1.1.3. There is so much changing every two months, that the steps between releases are quite huge, so that people following developer releases instead of CVS may have a harder time reporting bugs based on releases only. I originally hoped to do the developer releases monthly, but I find that it usually takes an entire weekend to get it out, so I'm happier with the two month schedule, just from a personal time commitment perspective. I imagine that when the big merging settles down, it should be less of an issue. This should be the last development release before we get serious about putting together a real production release. Here's the dates I have penciled in for that: Sunday, January 18, 2004 - Feature Freeze for 1.2.0 Sunday, January 23, 2004 - Release Candidate - 1.2.0-rc1 Sunday, February 1, 2004 - Release Candidate - 1.2.0-rc2 Sunday, February 8, 2004 - Release 1.2.0 (Production Release) I'm not so optimistic about a stable release that soon, as I don;t think we should really cut that one based on time passed alone, but also define a list of features we want to see in, as well as platforms we want to see run, applications we want to offically list as supported in 1.2 etc. For example, I think we shouldn't release 1.2 before the switch to GNU Classpath is completed. Okay, I think some release goals would be a great thing to have. On the other hand, I don't want to have 1.0.7 on the website as our production release for too much longer, so I think we should still pick a date. Eighteen months between production releases is already a long time. If we slip on the goals, then we can postpone the release. Since we don't have dedicated developer resources, we've got to be careful that the slippage doesn't get out of hand, or the release will never happen. So we should keep the goals pretty minimal. I believe that a real solid, supported production release would really encourage a lot more people to give Kaffe a try, and to get more involved. A perpetual stream of unsupported developer releases won't do that. Let's postpone setting a date for the production release until after 1.1.3 is out. Maybe we'll do a 1.1.4 development release. We need to have a discussion about what should constitute the release goals for the production release. I think that will be easier once we have some decent documentation that shows where we are. Given the moving target nature of what we are doing, we might want to identify a core set of APIs, ports and features that we support, and mark the rest of the stuff as experimental/unsupported. It would be nice to identify certain applications and certify that certain versions of them work on the Kaffe production release. I'm glad to hear it's actually working for something, browsing the list traffic I sometimes catch myself thinking: how are we ever going to fix all these bugs ... ;) But I guess that's just the effect of kaffe getting better, and more people trying it out where it hasn't been tried out before (or for a long time ;) That's so true... :-) Cheers, - Jim ___ kaffe mailing list [EMAIL PROTECTED] http://kaffe.org/cgi-bin/mailman/listinfo/kaffe

[kaffe] Planning for 1.1.3 release
Hi, It's getting to close to that time again. Isn't having a regular release schedule fun? Here are the upcoming dates I'm shooting for: Sunday, November 30, 2003 - Feature Freeze for 1.1.3 Sunday, December 7, 2003 - Release 1.1.3 If I've been somewhat quiet lately, it's mostly because I've had a real nasty cold for the last few weeks, and I've got a few side projects on the go that are eating up my project time. I promised some DocBook documentation, and I haven't done it yet, so that's still the highest thing on my personal priority list. I feel the lack of structured documentation is really holding us back in a lot of ways -- I've got a plan, I just need to make some time to do it. I still need to polish off my regression testing reporting framework as well. If anybody else has some goals for this release, please follow up to this email. This should be the last development release before we get serious about putting together a real production release. Here's the dates I have penciled in for that: Sunday, January 18, 2004 - Feature Freeze for 1.2.0 Sunday, January 23, 2004 - Release Candidate - 1.2.0-rc1 Sunday, February 1, 2004 - Release Candidate - 1.2.0-rc2 Sunday, February 8, 2004 - Release 1.2.0 (Production Release) Now for some wishlist items about the top things I currently care about (feel free to add what I've missed): - Improved documentation - Improved testing - Improved processes for keeping in sync with projects such as Classpath - Enough NIO support to get the latest builds of Freenet and Ant working - More testing and bugfixing on the verifier and security APIs - Make Kaffe work as a Mozilla plugin - Improved profiling and debugging support - Fix the Cygwin port, and Mac OS X port (eg. working PowerPC JIT). If we have decent support for all the major desktop environments, we might win some users over. - Easier support for graphical apps, with the ability to switch between multiple AWTs at run-time, etc. Again, these are wishlist items, so I'm not making any promises that we will deliver these. But I'm definitely willing to throw in some of my own time to help drive these forward. I'd be really happy even if we just make a small bit of progress on these items. Sun will kick out Java 1.5 in the Spring, I think, so we'll be playing catch up once again. But it would be nice to have a really solid production release in the Spring that we would be happy to say we support. I'm pretty amazed by how far Kaffe has come in just the last few months.

What, may I ask, are those of us using Cygwin supposed to do now that there is a `#error' directive in our md.h? I assure you that sigcontext will *NOT* be implemented anytime soon (trying to emulate POSIX signals via Windows signals is extremely complicated). I'm also certain this will also affect other non-linux platforms which use newlib. This was done by Guilhem Lavaux as part of the process of switching over to the Classpath I/O libraries. I haven't visited the problem myself, so I hope he can comment on the technical details. In general, I'd like to see Kaffe have the ability to be portable to non Posix platforms. It can be done, and has been done, but a lot of the work hasn't been merged back in yet. Why can't kaffe fall back to the prior signal handling when sigcontext is absent instead of being so heavy handed as to drop an #error directive (like it used to)? Tons of other, possibly more complex, projects seem to cope quite will without advanced signal handling. So what makes it so necessary now? Yes, I understand that java needs access to lowlevel routines at times, but you don't see this approach being done in libjava/gcj. IMHO, these recent changes make kaffe terribly unportable, which is something I thought most developers strive to avoid. Sorry if this sounds negative, but previous efforts led me to believe that making kaffe portable was one of its goals. Cheers, Nicholas Falling back to the previous behaviour sounds like a good idea. I wonder how much it is to put that back in? Patches are welcome. The biggest problem with supporting platforms like Cygwin is that we currently don't have anybody actively maintaining it. Even when I tested it last, circa 1.0.7, it seemed pretty broken to me. I think I would have been screaming pretty loud if what Guilhem did actually broke the port, but since it wasn't really working too well in the first place, I feel it falls more into the category of bitrot than actual regression. Again, Windows is an important platform, I'd love to see it work, but we need more help. Cheers, - Jim ___ kaffe mailing list [EMAIL PROTECTED] http://kaffe.org/cgi-bin/mailman/listinfo/kaffe

It would blow up the CVS by having some intially redundant code, but that could be phased out, as kaffe's and pockelinux' AWTs merge, and their java side is gradually moved over to classpath. what do you think? I'll all for compile-time switching of AWT implementations. Ideally, it would be nice for other things to be selectable at compile time as well, eg. the threading implementation, the garbage collector, etc. Of course, we'd want to keep the ability for embedded users to be able to compile in only one implementation, so they can save space. As far as the AWT goes, it would be nice to have a standard way of packaging up AWT implementations so they can be installed with any JVM (or, at least, the free ones). eg. Clemens Eisserer packaged up Kaffe's AWT so it could be installed elsewhere, eg. on gcj. http://xawt.sourceforge.net/ There are lots of AWT implementations floating around.

[kaffe] Kaffe 1.1.2 Development Release available for download
I've made the 1.1.2 release of Kaffe available for download at: ftp://ftp.kaffe.org/pub/kaffe/v1.1.x-development/kaffe-1.1.2.tar.gz http://www.kaffe.org/ftp/pub/kaffe/v1.1.x-development/kaffe-1.1.2.tar.gz As this is a development release, it is essentially a snapshot of what's happening in CVS, with limited testing. Even though this is not a production release, it contains a lot of improvements over 1.0.7, which was release over half a year ago. I anticipate that most people will have less trouble with this release. Here are some highlights of new things done since the last development release: * New packages: * javax.net * javax.net.ssl * Lots of configuration/compile fixes, including: arm-linux, parisc-hpux, parisc-linux, sparc-solaris. * Improved RMI, JVMPI, java.text and NIO support. * Improved garbage collector and jit3 memory consumption. * Further merge with GNU Classpath: Collections, many networking, IO and zip classes. * Fixes for several bugs in kjc. * Improved support for building without GNU make. * Lots of bug fixes, compiler warning fixes, and small improvements. * Some successes: Tomcat4, eXist, JavaLayer, JOrbis. Most of the verifier code was checked in, but it is not enabled by default yet, as it requires some further work. The focus of the recent development was largely related to migrating our class libraries over to Classpath. A side-effect has been that a lot of the non-mainstream ports have seen regression, and will need some additional work before they will be functional again. We're going to try to stick to the schedule of doing a development release every two months, culminating in a heavily tested production release (1.2.0) in early 2004.

Hash: SHA1
Hi Jim,
I needed to patch java.net.HttpURLConnection and java.net.URLConnection
to be able to compile Jetty-4.2.12. The patches bring those 2 classes
up2date with JDK 1.4. I'm not sure who to send this stuff to and therefore
sent it to you.
Regards, Chris.

Are you sure you want/need to use them? Yes. Actually, if the target is a java'ish machine then they will have to take care of any of that legalese themselves. The config.sub thing is not a java'ish thing itself here. - Furthermore, the use context is obviously talking about compatiblity with a certain vm type and not identity, as expressed in a lot of corners and we know that config.sub simply trying to get a canonic variant of certain arguments given. jvm, java and similar names _are_ the canonic variant of anything quite like it but not the product (trademark!) itself. AFAIK sun has quite strict rules about claiming compatibility with any of their Java products. Basically, you can't do it, unless you shell out big bucks for a license to their code. But I may misunderstand what you want to say. Sun has a lot of lawyers, and they've been pretty aggressive than most about staking their claims on the linguistic turf (so they can sell it off). Because they claim Java Compatible(tm) as a trademark, it makes it hard to use a normal noun+verb sentence to say that we're compatible with Java -- we are, by most dictionary definitions, but we're not Java Compatible(tm), under Trademark law. Maybe we can say that we're interoperable? :-) Anyways, the config.sub name is just going to be used to define a target - so it makes sense to call the target Java, since it's only going to be used by tools generating Java byte code, which will run on Sun's JVM. Of course it will still run on other virtual machines that can't use the Java trademark, but that shouldn't be of any concern to the tools generating the code, IMHO.

Re: [kaffe] Planning for 1.1.2 release - XAWT obsolete?
On Tue, 23 Sep 2003 18:47:28 +0200 Clemens Eisserer [EMAIL PROTECTED] wrote: Hi there! Nope. GNU Classpath AWT integrating should happen for the 1.1.3. Does this mean the current kaffe-xawt implementation will be thrown away? Not at all. We already support multiple AWTs -- this would just be another one, I imagine. This was the best awt implemenation I´ve every seen, and I dont understand why gnu-classpath isnt based on this awt. I think it comes down to ownership/licensing dynamics (eg. Transvirtual never transferred copyrights to the FSF for the AWT). The only problem are the ugly widget LF´s, but should be possible to make this whole thing skinable without big troubles. Yeah, the LF is definitely ugly. :-) I haven't done too much AWT stuff myself, but I think we could serve as a useful place to experiment with AWT integration since we have somewhat looser licensing constraints than other projects. Here's what I'd like to see: 1) Multiple AWT implementations a) Some using lightweight widgets, where the widgets are drawn in Java. eg: - our current X AWT - Swing (we can run Sun's old AWT based one, and should be able to run their newer Java2D based one if we get a Java2D implementation) - others, eg. Rudolph (from Wonka) The Transvirtual version of Kaffe had a lot of additional AWT work done on it. The big thing was it had a lightweight AWT that could render to a no-native-wm backend, which provided a pluggable backend for the core graphics primitives on a number of platforms (X, Linux framebuffer (using the fgl library), Wind River's UGL, GRX, MGL, Allegro). The no-native-wm backend sounds similar in concept in many ways to what Java2D does - it might make sense to move that stuff into a Java2D implementation. There is probably additional window-manager functionality that Java2D doesn't cover. Transvirtual's AWT and Swing both provide support for skins / LF's. As far as backends go, I think it would be cool to experiment with even more extreme Java-only solutions, eg. driving a framebuffer as a Java byte array, or writing a xlib completely in Java! Graphics backends are really interesting, because the challenges involved in utilizing modern graphics acceleration hardware are interesting. Things like Cairo and DirectFB on Linux, DirectX on Windows, and Quartz on Mac OS X provide use ways to get access to accelerated hardware. If we had a really good Java2D implementation, it might even be feasible to use something like WeirdX as a more flexible replacement for XFree86 to support legacy apps. :-) b) Some using native widgets. These provide tighter integration on some platforms. - Gtk - nice for Gnome desktops. There's a version of Gtk which will render to the framebuffer too. - Qt and Qt/Embedded - Win32 (for Windows) - there was a MicroWindows AWT for Kaffe based on the Win32 widgets, I think. - a Carbon based AWT for Mac OS X would be nice - Motif/Lesstif would be interesting, just because it's what Sun used in their original AWT - SWT apparently works, which works with Win32, Motif, and Gtk. It would be cool to do a SWT backend that used lightweight widgets. Note that some of these widget sets are themeable themselves, and can use multiple backends as well. eg. Qt is essentially a lightweight widget set that renders it's own widgets on the platforms it supports. Conceivably, it could even be made to use a Java2D backend. :-) 2) Compile-time switching of AWTs All these AWTs should be configurable at configure time. For embedded platforms, it's nice to be able to select only one specific AWT tuned to the target platform. Transvirtual took this to extremes with fgl, where even the color depth was chosen at configure time. 3) Run-time switching of AWTs It would be nice to be able to configure Kaffe with multiple AWTs, and have them selectable at runtime using a property. If somebody wanted to do something even more extreme, I imagine that it would be possible to create and API to enable applications to use multiple AWT implementations simultaneously. :-) Sascha Brawer is organizing a free Java AWT BOF at Linux Kongress - that should be interesting: http://www.linux-kongress.org/2003/bofs/index.html Anyways, I don't think there is a one-size-fits-all solution for graphics on Java - I'd like to keep an open mind, and hope some really nice interfaces and implementations evolve.

Re: [kaffe] Under which license stands Kaffe´s-Classpath?
I think it's a noble idea to merge as much stuff as possible into Classpath and to encourage future development on Kaffe's class libraries to happen there. The Qt AWT port was done by Murphy Chen and Ken-Hao Liu of Dialogue Technologies. However, I notice that a lot of the source files still say that they are copyrighted by Transvirtual Technologies, Inc. - I assume they derived those files from the AWT that is already there. So I think you can assume that these are going to be under the same license as Kaffe, which is GPL. Transvirtual doesn't really exist anymore, so it might be difficult to find who owns the rights to the intellectual property, and to try to convince them to relicense the code. It's a matter of interpretation as to whether or not it's illegal to use proprietary apps with GPL'd class libraries. I think that's been discussed to death on the list already. I don't think I want to re-open that discussion, since there isn't a whole lot we can do about it, other than rewrite Kaffe from scratch.

I´ve ported kaffe´s AWT to GCJ so that it is now possible to create standalone native awt-based apps. Maybe even kaffe could profit, because if bugs or improvements are done by GCJ-people, these improvements are still copatible to kaffes awt. The problem is, that I ever thought, that Kaffe´s Classpath stands under LGPL, but in the AWT-Files is a license-notice that points me to GPL2 (maybe the link is wrong). Does that mean its not legal to use proprietary awt-apps with kaffe? GCJ´s classpath stands under a special GPL license which allows commercial companies to link against libgcj withought making their code gpl, but its not allowed to modify the libgcj-code and sell it withought GPLing the result (like this is possible with LPGL). It would be really important for me that my ported version stands under the same license as GCJ´s classpath or LGPL.
