rssowl: libgcj bugs that need fixing for it to run
by Robin Green 28 Jul '05

28 Jul '05

I have also been working in my spare time on packaging rssowl for FC5 [sic]. I can post my .spec file if wanted. Here's my list of unfixed libgcj bugs that need to be fixed before rssowl will run natively reliably. These are both threading bugs. 1. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22211 "Thread.interrupt sometimes causes abort if thread is already dead" This gets hits about 25%-50% of the time on quitting rssowl, and occassionaly also when I press the little red stop button at the bottom of the window. I can provide a backtrace if wanted. Unfortunately rssowl only saves any changes upon quit, so this means that any changes (including preferences and even the record of which feed items have been read) will be lost 25-50% of the time - unacceptable, obviously. 2. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13212 "AttachCurrentThread() not working" This is an old bug. It only triggered for me once I rebuilt gcc for Athlon (32bit) with a private threading patch, but now it triggers 100% of the time, every time I try to view the Dilbert comic in rssowl. Again, backtrace available on request. I am convinced that it is a real bug in the existing code, not a bug in my patch. After all, bad memory accesses don't always trigger SIGSEGVs. Sometimes they just cause memory corruptions. So probably, previously it was just causing memory corruptions instead of SIGSEGVs for some subtle reason. Feel free to add to this list. -- Robin

Java API doc (javadoc) from GCJ/classpath?
by Ian Pilcher 07 Jul '05

07 Jul '05

From what I can tell, Fedora Core 4 provides a very good Java 1.4.2 development environment. The one thing that I cannot find is Java API documentation (the equivalent of JPackage's java-1.4.2-sun-manual). Have I just missed it, or is it not available? Thanks! -- ======================================================================== Ian Pilcher i.pilcher(a)comcast.net ========================================================================

Weird ecj + utf8 issue
by Andrew Overholt 03 Jul '05

03 Jul '05

I came across a weird issue while trying to build rssowl. I've attached the test file. Trying this works: ecj RSSOwlI18nZHtw.java while this appears to hang: ecj -encoding utf8 RSSOwlI18nZHtw.java I can reproduce this behaviour on both an x86 box running an Eclipse 3.1 ecj (built myself) and on a ppc box running Eclipse 3.1 RC3 (the RPMs we have in rawhide). Using Sun's javac (on the x86 box) does not hang when I use "-encoding utf8". All are FC4 machines (with gcc*-4.0.0-11 in the x86 case and gcc*-4.0.0-13 in the ppc case). To add to the bizarre-ness, this appears to be as small as I can make the test file without it being unable to reproduce the problem; I can't seem to remove any of the lines if I want to continue to reproduce. In another interesting twist, renaming the file (and class) to "TestUTF8" does not reproduce the problem. Anyone know what's going on? Andrew

JOnAS in FC5
by Gary Benson 30 Jun '05

30 Jun '05

Hi all, Those of you who are interested in JOnAS might like to know that the version I just built, jonas-4.3.3-1jpp_3fc, actually a) runs and b) serves pages! It's very crunchy at the moment, but any testing will be sorely appreciated. NOTES 1. When you try and start it note that "service jonas start" never returns control to the shell so you'll have to tail /var/log/jonas/jonas to see when it's started. Look for a message like "The JOnAS Server 'jonas' version 4.3.3 is ready". 2. It locks up during startup fairly frequently. If the last line in /var/log/jonas/jonas is "jmx service started" or "jtm service started" then you probably want to kill it and have another go. 3. You may get a load of database errors. If so, try removing dbm from jonas.services in /etc/jonas/jonas.properties and uninstalling the jonas-examples rpm. 4. "service jonas stop" doesn't seem to work, but the server can be halted quickly and easily by trying to look at the memory graph in the admin application. Enjoy! Gary

Re: postgresl-jdbc incompatible w/ Fedora Core

And I'm sure this stuff would not be limited > to postgresql-jdbc. I don't understand your argument. Are you saying that the file can never be changed? Probably, it should be put into it's own package in the Fedora repos. There's a larger question here. What is the "co-existence strategy" for JPackage and Fedora Core? I'm trying to figure out how to set up a Java development/Tomcat server environment on FC4, and I'm very unsure how to set things up so that yum doesn't eventually leave me with an incompatible mishmash of JPackage (Java) and Fedora (gcj) packages. > Maybe the FC postgresql-jdbc package could have a versioned Provides: > using the full version number (including the build) of the drivers it > contains, like the corresponding JPP one has in its version field? > Would that work the way you'd expect? (What would you expect, BTW?) Getting the Fedora postgresql-jdbc package to somehow reflect the version of the driver would be a good start. I'm not sure how to do this, though. I haven't had great luck getting responses to bugs that I put into Red Hat's bugzilla, let alone RFEs. There's also the fact that the Fedora package contains multiple builds of the driver, for use with multiple JVM versions; the JPackage package only contains a single build (JDBC 3?). So even if the JPackage RPM were updated to a later driver version, there's a case for not replacing the Fedora package. Out of curiosity, what distributions *don't* include the PostgreSQL JDBC drivers? (I.e. why does the JPackage RPM exist?) Thanks! -- ======================================================================== Ian Pilcher i.pilcher(a)comcast.net ========================================================================

System freeze when running Eclipse as root
by A.J.Delaney＠brighton.ac.uk 28 Jun '05

28 Jun '05

Hey all, I know it shouldn't be done, but we ran Eclipse as root. It seemed to freeze the whole system, mouse pointer, keyboard input etc... No kernel panic was produced and Eclipse runs fine as a normal user. Is this well known behaviour for eclipse? -- Aidan Delaney Lecturer, School of Computing, Mathematics and Information Sciences, University of Brighton.
