It still leaks memory, but I've learned to stop worrying about that. Whether it still crashes on assertions, I can't say yet. Even with 1.0.7 I could often run for hours or days between crashes. In the last almost-a-day, I've restarted it twice due to out-of-memory problems, and it hasn't crashed yet. Whether that's good or bad is, I suppose, a matter of taste. I suppose I should test it with a transient Freenet node on Linux, too, just to see if any weird bugs crawl out of it. It won't get the same kind of unpredictable hammering that a permanent node gets, but it's worth a try. -- Greg Wooledge | "Truth belongs to everybody."

I've got gmp 3.1.1 installed (the old OpenBSD 3.2 port, since the early-May Kaffe I was using is still dynamically linked against it).

Good it works (more or less, haven't a clue about the coma thing). Bad it is slow. The same code is used in gcj where is doesn't seeem slow at all but that might be because gcj is an ahead-of-time compiler that can much better optimize this code then the kaffe just in time compiler. The GNU Classpath implementation is based on the pure java gnu.math.MPN class which says: /** This contains various low-level routines for unsigned bigints. * The interfaces match the mpn interfaces in gmp, * so it should be easy to replace them with fast native functions * that are trivial wrappers around the mpn_ functions in gmp * (at least on platforms that use 32-bit "limbs"). */ So one approach might be to create a gnu.math.MPNNative that actually wraps the gpm functions. > So, the upshot is, I'm still running early-May CVS Kaffe. It's the > only thing that still works. But I didn't know that it already worked with an older kaffe version. Can you determine on which date it actually broke? The strange thing is that the last work on the kaffe implementation of BigInteger is from Januari.

Slw. But I suppose if it's all that works. OK, here we go. I started by updating from OpenBSD 3.2 to 3.3. Then I ran Freenet with Kaffe from early May, which is what I've been using normally with rather good results. This seemed to be OK, just as it was before the OS upgrade. Then I tried building recent CVS Kaffe (I think it's about 2 days old now). I got the same results as before: "Negative bit address", whatever that means, whenever I tried to access a document. Then I upgraded gmp from 3.1.1 (the OpenBSD 3.2 port) to 4.1.1 (the 3.3 port). I rebuilt Kaffe with that version of gmp, and still got the same results: "Negative bit address". Next, I tried with --enable-pure-java-math. This seemed to be working better; I could run the node and retrieve documents via fproxy (the web interface) without "Negative bit address" errors. But, as Toad said, it's incredibly slow compared to gmp. Running top, I saw kaffe-bin take about 30-40% (with spikes up to 90%) of the CPU when I hit a few image-heavy pages. Normally I don't see it get over 50% even when it's doing FEC decoding -- under normal conditions, like retrieving a few pages of images, it never got over 20% or so. Then, after about 1:30 of CPU time, the node went into a "comatose" state. I see this fairly often even with the early-May Kaffe; the node just sits there, not eating any CPU; sometimes it pulls out by itself after a few *minutes*(!), but usually it's time to restart it. After waiting about 5 minutes, I restarted it. Meanwhile, stdout/stderr had this: kaffe-bin in malloc(): warning: recursive call. kaffe-bin in malloc(): warning: recursive call. kaffe-bin in malloc(): warning: recursive call. And freenet.log had this: 03-Jun-03 10:42:16 PM (freenet.interfaces.PublicInterface, Interface # tcp/36963, NORMAL): Getting thread to dispatch in PublicInterface took more than 10 seconds! If this happens frequently, report it to [EMAIL PROTECTED] Waited 101231 millis. java.lang.Exception: debug at java.lang.Throwable.fillInStackTrace(Throwable.java:native) at java.lang.Throwable.(Throwable.java:44) at java.lang.Exception.(Exception.java:24) at freenet.interfaces.PublicInterface.dispatch(PublicInterface.java:109) at freenet.interfaces.Interface.acceptConnections(Interface.java:220) at freenet.interfaces.Interface.run(Interface.java:172) at java.lang.Thread.run(Thread.java:334) (This occurred several times.) Pretty soon, the restarted node had ground itself down into a coma just like the first time. top showed the CPU usage had dropped to nothing, with about 1:33 elapsed CPU. No more images were coming through on the web interface. There weren't any messages in the logs this time, though. So, the upshot is, I'm still running early-May CVS Kaffe. It's the only thing that still works. -- Greg Wooledge | "Truth belongs to everybody." [EMAIL PROTECTED] |- The Red Hot Chili Peppers http://wooledge.org/~greg/ | pgp0.pgp Description: PGP signature
