native eclipse freezing
by stemeri 12 Apr '05

12 Apr '05

With all updates OK on rawhide (on a daily basis), I have troubles with native eclipse. It looks like this post : https://www.redhat.com/archives/fedora-devel-java-list/2005-March/msg00265.… However, some more informations: Launching eclipse as a user is perfect and CDT (I develop only in c++) is working for me. However, launching eclipse as root freezes the computer. Only way to go : hard reset (no alt-sys..., no ssh, ...). __________________________________________________________________ Découvrez le nouveau Yahoo!

Eclipse 3.1M6
by Andrew Overholt 12 Apr '05

12 Apr '05

I put together some rudimentary RPMs for Eclipse 3.1M6. I tried them very briefly and they appear to work. Give them a shot if you have a chance. I'd appreciate any feedback. RPMs: http://people.redhat.com/~overholt/eclipserpms/ SRPM: overholt.ca/rpms/eclipse-3.1.0_fc-0.M6.1.src.rpm Thanks, Andrew "yes, I should get my disk quota upped" Overholt

Eclipse UI Tests
by Andrew Overholt 11 Apr '05

11 Apr '05

Hi, I was talking with Billy last night about Eclipse unit tests and I ran the UI ones this morning. There are 806 tests and we get 152 Errors and 40 Failures. 144 of the 152 Errors are from org.eclipse.ui.tests.dnd.DragTestSuite in which Billy said to expect errors (since this is 3.1M5a I'm testing). I'd like to set things up to run these automatically (Aaron is looking into it) and get some hard data that we can work with. The one thing that bothered me is that the tests took about 43 minutes to run on my P4 3 GHz with 1 GB RAM. Billy says the tests take only about 10 minutes normally. I'll try to spend some time figuring out where the time goes. This could have been my machine/setup but they took about the same amount of time to run on my laptop which is a much less beefier machine so I sort of doubt it. This is how Billy taught me to run the tests (for future reference): . start Eclipse with a new workspace eclipse -data testworkspace . switch to CVS perspective and add the Eclipse repo (dev.eclipse.org - /home/eclipse - anonymous - pserver) . expand the Eclipse repo and expand versions . expand org.eclipse.releng . expand I20050219-1500 (the tag for 3.1M5a) . expand maps . double-click on ui.map . note that plugin(a)org.eclipse.ui.tests=v20050218-1200 . close ui.map and expand org.eclipse.ui.tests . check out org.eclipse.ui.tests v20050218-1200 . switch to the Java perspective . once your workspace finishes building, there will be errors in a few things ... we only care about the errors in plugin.xml so edit it to comment out or remove the two offending lines . expand Eclipse UI Tests -> org.eclipse.ui.tests . right-click on UiTestSuite.java and click Run As -> JUnit Plug-in Test . beside Package Explorer and Hierarchy, you should get a JUnit tab; quickly select it and select the Hierarchy tab within before the tests start up . let the tests run without playing with your computer because some of the tests rely on focus Andrew

Re: [JPackage-discuss] Why libswt3-gtk2 isn't split between lib and plugin? also multiple SWTs and GCJ binaries

I recently added the requirement on java-1.4.2-gcj-compat because we don't want people to think they're running our native packages when they are actually running them on a proprietary JVM. If someone has their alternatives set up for, say, the Sun JVM, our packages will work without the native bits (all the .jar.so files) entirely. > more GCJ bugs reported, etc), but it will make a fork on JPackage RPMs > and users will not be able to update to new versions using JPackage > RPMs. David Walluck and I have been talking about adding some sections to our (FC) RPMs so that they are basically the same as the JPackage pure bytecode ones.

No. :) Many discussions took place about this and that's not the direction that we decided to take.

If you have j-g-c set up as your java alternative and you run Eclipse, it'll use the natively-compiled stuff. If you have another JVM set as your alternative, it will seamlessly use it and ignore the native bits. > PD: I made a fast search on the list to find something on this, I > apologize if it was discused before. That's cool. Not much of this was discussed on list and I apologize for that. Thanks for the interest and suggestions! Hopefully my comments clear things up a bit. Andrew

Patch to find-and-nativify
by Robin Green 11 Apr '05

11 Apr '05

This proposed patch makes 4 changes to the find-and-nativify in java-1.4.2-gcj-compat-1.4.2.0-40jpp_14rh. - Generates a database as it goes, rather than forcing the spec file writer to write a similar script to build the db. - Qualifies each lib with the package name, to avoid name collisions in Provides. (Which suggests the thought that since package names _must_ be unique by design in rpm - isn't it then sufficient to generate libs in %{_libdir}/%{name} instead of as %{_libdir}/%{name}/full/path/to/jar ?) - Ignores jars which are symlinks (they might not even be in the package, and if they are, you will end up compiling them more than once.) - You can set the SKIPTAR environment variable to skip the tar building, for more efficient rpm builds. I have a handy utility script to post next which assumes some of these changes, so I will wait to see what happens to this patch first. -- Robin --- find-and-nativify.old 2005-04-10 22:28:23.000000000 +0100 +++ find-and-nativify 2005-04-11 00:02:59.000000000 +0100 @@ -12,20 +12,33 @@ (ex. eclipse) BUILD_OPTIONS - a list of gcj options to pass to nativify (outside of -findirect-dispatch, -shared, and -Wl,-Bsymbolic) + + By default, the generated database will assume libraries will go in /usr/lib. + To change this, set LIBDIR to the appropriate directory. + + Set SKIPTAR=y to skip tar file creation.

Debugging native java libs loaded via lookup in classmap.db
by Robin Green 08 Apr '05

08 Apr '05

Currently, it seems impossible to set breakpoints with gdb in native libraries loaded via the new classmap.db mechanism, aka the 'BC API'. (I know that the library in question _is_ being loaded, because it appears in a stack trace in the debuggee!) I have filed this problem as gdb PR 1907 (see http://sources.redhat.com/cgi-bin/gnatsweb.pl?database=gdb ). -- Robin

CC-ing to fedora-devel-java-list Surely there must be a GPL-friendly PNG handler in Java somewhere? How hard would it be to rewrite this part of FOP? What's the status of getting a natively-compiled FOP into Fedora?
