Re: [Classpath-inetlib] Important request, participation in software development study
Dear Engineers, Yesterday I sent a message asking for help with a survey, some of you suggested that I create a form that does not require login. I beg you to help me with this survey, it really is important. If you have a Google account: https://docs.google.com/forms/d/e/1FAIpQLSdG4bhNWfU3vzSKwG-0j8NuGW47_xmSY1ftF33gaNAZsU25kA/viewform Reply without logging in: https://docs.google.com/forms/d/e/1FAIpQLSeNm99cxIyT65-5qR6ZCZoDNeFONTf_ODWbXaSxUskkxbWu4g/viewform I also ask you to send this survey to other developers that you know and respect. Please help me, I promise that your contributions will be recognized in the publications that are possible, therefore, as an optional field I have included the name and email. My biggest goal is to unify all non-formal models to create a modeling language that is the heritage of the industry, built by all of us. If you want to know more, you can write to me at ivan.arr...@uma.es, ivandarioarr...@gmail.com or arco...@gmail.com !!THANKS ___ Classpath-inetlib mailing list Classpath-inetlib@gnu.org https://lists.gnu.org/mailman/listinfo/classpath-inetlib

I think you need an handler to perform the correct logging, because by default if I remember correctly only critical logging is performed. I don't remember any more how we do it in GNU Classpath, I'm quite sure the mechanism is the same though (and I'm sure it was working). For the JDK, you need to configure a file called logging.properties, this will take the settings for the logger, like the level of logging and the handlers to use for the logging. Here is a very basic introduction to logging in general: http://www.crazysquirrel.com/computing/java/logging.jspx If you need help in this specific case, ping me and we can try to give it a look together.

I've found what seems to be a bug in the gnu.inet.util.BASE64 class: The

library wasn't updated in years. Is it deprecated? Is there any
alternative?
This class is used in the gnu javax.mail implementation, and is
preventing me from authenticating with a server.
If you confirm me that the padding characters should be there and this is
a bug, I can make and send you a patch.
I'm pretty sure this was an old bug that was fixed a while ago. Check that
you're using the most up-to-date release.
If it's still not working, please feel free to send me a patch against CVS

Hello again,
sorry for the delay. I've been busy, then the holidays...
I've checked the CVS head code and I've found the error: the length of the
target array was wrong. I've checked the history of this class too. It seems
that this issue was already detected, but the fix was wrong and was reverted.
I attach my patch (base64len.patch), which corrects the length of the target
array (so there's no need to truncate, I've removed that code), and
uncommented the code to fill with padding simbols again.
The second patch (base64dec.patch) is for the decode function. That function
works ok, but I detected something odd with the target array length. First, a
buffer with an arbitrary length is created, then it's truncated to the
correct size. But the length of the target array can be known beforehand,
there's no need to truncate the array at the end.
With this patch, the method will throw an arrayoutofindex exception if the
given array length is not divisible by 4, which I think is ok, since the
result would be incorrect.
Please, let me know if you are going to apply the patch (specially the first
one).

Thanks, Ian This would be helped if the bugs were narrowed down and filed as Classpath bugs against current CVS, rather than being largely unhelpful stack traces against Classpath 0.97 that are difficult to reproduce. There are few people actively working on GNU Classpath today so any help to reduce the leg work required to fix bugs is much appreciated. Reading the RVM bug, the two issues confused me. The Class issue seems JikesRVM specific and indeed, Classpath has been compiling javac since it was Freed in 2006. In fact, I'm not sure this wasn't also fixed in a recent rvm commit; it doesn't appear in the JAPI run. The XML issue I thought was also seen before, but it may just be very similar to another. It's definitely worth filing that on Classpath as I doubt Chris, who wrote the JAXP packages, will be monitoring RVM issues. Thanks, -- Andrew :-) Support Free Java!

It is possible, and you can merge them as much as you like, and publish merged versions yourself. That's part of what the BrandWeg project by Andrew Hughes is about, and you're most welcome to help out on it. In FSF's case, we'd like to keep our code under GPLv2 or any later version, to allow the Classpath project to be upgraded to GPLv3 or any later version by any user, while in OpenJDK's case, we're on GPLv2 exclusively. The FSF is reluctant to add code to GNU Classpath that would make an eventual upgrade to GPLv3 harder than necessary, as the FSF strongly prefers GPLv3 to GPLv2. It's a policy issue, rather than a licensing issue, per se. Also, on a side note, why can't Classpath OpenJDK merge? Both projects do the same thing They could merge, it's just a lot of work to actually perform a manual, best of breed merge on two such large, independently developped codebases, doing all the developers that have done the work on them justice. When we merged Kaffe with Classpath, we eventually just ended up replacing large chunks of Kaffe's code with Classpath's code, regardless whether it was technically better or worse, simply to avoid having to maintain it ourselves. That worked, socially, because most of the developers of the class library in Kaffe had by then moved on to other projects, and the next generation saw a clear need to perform the merge. In Classpath's case, the need for a merge withing Classpath is offset by the ability of VM authors to do any merge they want in their own projects, and adapt the VMs to work with OpenJDK's class libraries, without having to adopt OpenJDK's policies, just like they don't have to adopt FSF's policies. So we're currently seeing several different approaches being experimented with in different VM projects, including OpenJDK, where Andrew is working on a stable VM interface to make plugging different VMs into OpenJDK easier. cheers, dalibor topic

I tried to follow the instructions at http://developer.classpath.org/mediation/ClasspathHackingWithEclipse to set up my environment, but I’ve run into a couple of stumbling blocks. I tried first with jamvm. All of the steps in the wiki page work, but when it comes to debugging my application, jamvm complains that it doesn’t know what -Xdebug means. So I patched jamvm to ignore that (and -Xnoagent), but Eclipse also passed a -Xrunjdwp:transport=dt_socket,suspend=y,address=localhost:37927 command line argument, and that looks like something that couldn’t be just ignored to get debugging working properly. Does jamvm support debugging from Eclipse? No it does not. I also tried with cacao, grabbing the sources from the hg repository. Again, the steps in the wiki succeeded, but when it came to debugging, Eclipse tells me: main: lt_dlsym failed: /usr/local/jdk1.6.0_03/jre/lib/i386/client/libjvm.so: undefined symbol: vm_createjvm Anybody know what this could be? (I presume it’s mentioning jdk1.6.0_03 because that’s VM that Eclipse itself is running on.)

For example, -J-Xms48m sets the startup memory to 48 megabytes. Although it does not begin with -X, it is not a `standard option' of javac. It is a common convention for -J to pass options to the underlying VM executing applications written in Java. Well, I don't see any actual bug in Sun's javac. It runs with a size-limited heap, and the default size is too low for us (I run out of java heap space). That's Sun's design decision, we have to live with it and work around it. If Classpath knows that javac needs more heap for compiling @classes, it should automatically pass the corresponding -J-X options to javac. This should not require manual manpage reading and makefile fiddling. -J-Xmx128m still bombs out (but later than the default), -J-Xmx256m works for me. Greetings -- Klaus Kusche, DI.

You don't need to; you should be touching the Classpath or ecj components
within the jikesrvm tree, you just need to build JikesRVM and it will handle
these dependencies.

The out of memory error with CACAO and old Sun' jres is solved long time ago, and the solution is described at http://developer.classpath.org/mediation/ClasspathDeveloperGuidelines. But if you just use the unmodified Fedora installation, it is likely still gij - based and should run ecj using all available memory without problems. Sometimes it may be really difficult to figure out that is going wrong without having hands-on access. However you should read carefully the GNU Classpath hackers guide, trying to follow all steps exactly. Also, try to run the application 'top' (while compiling) in another window. If it shows that the running process really swallows all your memory (swap including), you need to upgrade the machine and likely nothing else can be done. Read about various .configure options and search the web. If you really cannot solve the problem yourself, please post questions to the GNU Classpath discussion mailing list, not to the individual developers. Then the answered question will stay in the mailing list archive and another person with the similar problem will be able to find it with the simple Google search. Also, hackers typically prefer not to start long individual consultations as it takes for them too much time. When posting to the mailing list, do not forget to attach all error messages that the build script have printed for you. Just saying 'nothing works' does not help to locate the problem even when that is true. Good luck Audrius

The classpath exception on Sun's code would make that less of a problem for code in OpenJDK that would make sense to merge into Classpath. i.e. the class library code, as that code is licensed for the most part under GPLv2+classpath exception, so mixing and matching that code with GPLv2+classpath exception or GPLv3+classpath exception should be, per the exception, OK. If someone desperately wanted (i.e. volunteered) to make it happen, I guess we could bug the FSF mjw about a branch to do the work, or move that work to some other place, like icedtea, and resync from there (icepath ftw!). It's not really a pressing issue any more, in my opinion, as cacao ikvm have started to switch over to openjdk/icedtea libraries, and I'd expect other VMs to follow, as their resources permit. It'd be easier if an icedtea/classpath integration branch existed, but it seems possible to pull off that big merge without it, judging by Jeroen's and Christian's work. Meanwhile, there is a bug tracker full of regular maintenance work for those of us that can't just switch their VMs to icedtea's class libraries just yet, so I expect that we'll see more than a handful of releases of classpath until the big merge/switch happens. cheers, dalibor topic

It's not a matter of refusing to release code, the plugin simply hasn't been a priority for them yet, afaict. At FOSDEM, someone said that the plugin code for IE alone is about the size of the hotspot code, so it's probably a lot of work.

Re: Classpath / Icedtea Qtopia
Hi, 1.) Compilation of Classpath 0.95 with Qtopia 4.3 fails: When compiling qtembeddedwindowpeer.cpp, qx11embed_x11.h is included. This header exists in Qtopia, but is uncompileable: It needs the XEvent type, which exists only in X11-based builds of Qt. Any fixes for that? Not out of the box. The Qt peers are somewhat unmaintained at the moment. I did some splitting out in the GTK peers lately, so that they compile without X. I guess, something similar could be done for the Qt peers. Has anybody ever been able to run classpath on top of Qtopia? Not that I know. Any other options for framebuffer-based (X11-less) classpath? As I said, the GTK peers (in CVS HEAD) should be able to compile without X, and might or might not run on GTK/Embedded. 2.) Icedtea currently needs X11 and Gtk. Are there any plans to support other GUI backends in Icedtea (Qt / Qtopia, Escher, ...)? It would be a worthwhile effort to split out the Classpath peers, so that they can be used with OpenJDK/IcedTea.

I did some splitting out in the GTK peers lately, so that they compile without X. I guess, something similar could be done for the Qt peers. Unmaintained doesn't sound very promising. I had the impression that the Qt backend with Qtopia is less risky and more likely to get useable (and more stable and reliable for the future) than the GTK + directfb combination. Is it agreed that GTK + directfb is the way to go for X-less framebuffer, instead of Qtopia? Has anybody ever been able to run classpath on top of Qtopia? Not that I know. Well, I managed to compile it (in fact, the piece of code mentioned in my first mail was dead code: not called from anywhere...). It even starts and initializes the framebuffer (it fills the whole screen with a single color), and it seems to be alive (cursor moves when moving the mouse), but nothing more: It doesn't draw anything and doesn't react to input events.

the ugly proprietary javac already installed).Are there any thoughts on
including this in Classpath itself? I know ecj ignores the extra option (and
is only relevant if used as a 'javac' and not recognised as ecj a priori),
but gcj (my version at least) spits it out; maybe that could be fixed before
4.3 is released?
Thoughts?

Re: classpath on cygwin with gtk enabled
Hi, bj wrote: hey, does anyone here know how to compile GNU classpath on Windows XP using cygwin with GTK enabled or any graphics environment used by Swing and AWT? thanks in advance As far as I know, Classpath on cygwin is fairly untested, though there is some information at http://developer.classpath.org/mediation/ClasspathOnCygwin They intentionally exclude the GTK peers on that page, so I suspect they didn't work at the time. That page is quite old, however, and it's possible that things are in better shape now. If you want to give it a try, I'd be very interested in hearing about the results. I may be able to help if you run into some specific problems on the Classpath side, but I'm afraid I can't do much testing on cygwin myself. Cheers, Francis

Re: Classpath and gnu-crypto
What version of GCJ are you using? In recent releases of GCJ (or maybe the upcoming release -- I haven't been tracking this) GNU Crypto is a part of libgcj. Like Raif wrote in his reply, replacing gnu.crypto with gnu.java.security in your code will work in a newer GCJ release. Compiling Classpath itself with an existing GCJ will likely not do what you want. You *should* be able to compile the gnu-crypto Jar to an .so, however. The command line for that would be something like this: gcj -shared -o libgnu-crypto.so gnu-crypto.jar Then you should be able to link your program against libgnu-crypto.so. You may also find more help with GCJ on their mailing list: see http://gcc.gnu.org/lists.html, the GCJ mailing list is [EMAIL PROTECTED].

That was the plan, on the assumption that 0.92 is imminent.
Alternatively, we could also have a release branch for generics, but it

Note that some packages may have been already selected by the installer.
4. Download jikes-1.22
http://prdownloads.sourceforge.net/jikes/jikes-1.22.tar.bz2?download
5. Unzip jikes-1.22.tar.bz2 with one of the following utilities
winrar (Windows utility)
tar (Cygwin utility: $tar -xjf jikes-1.22.tar.bz2)
6. Apply the following patch to the file .src/platform.cpp
http://sourceforge.net/tracker/index.php?func=detailaid=1202863group_id=128803atid=712760

7. Build jikes-1.22
---
$ ./configure
$ make
$ make install
$ make clean
you can save yourself steps 4-7, since jikes 1.22 is now part of cygwin.
cheers,

8. Download Classpath-0.20
-
http://www.gnu.org/software/classpath/
9. Unzip classpath-0.20.tar.gz with one of the following utilities
---
winrar (Windows utility)
tar (Cygwin utility)
10. Build Classpth-0.20
$ ./configure --with-jikes --enable-gtk-peer
$ make
$ make install
$ make clean
The install process will print quite a few Java and C warnings.
Note also that, since jni is enabled by default, ---enable-jni is not
needed.
11. The building process will install the Classpath library here
-
/usr/local/classpath/share/classpath/glibj.zip
- The End
The time required to do everything is about 30 minutes on a 1 GHz PC.
If you are a developer, you might want to install the following packages,
which, by the way, are not required to build Classpath:
Devel/gdb (all files)
Devel/ddd (all files)
Devel/subversion(all files)
gdb is the GNU command line debugger, ddd is the GUI front-end of gdb,
and subversion is a utility to check-out and check-in the source code
of a versioned project.
