Re: Odonata+SableVM+Classpath works! (and bootclasspath question)

I haven't measured any speeds or memory usage but with regards to visual output SableVM is on a par with GIJ (both use GNU Classpath, I know, but I didn't want to assume that all JVM using GNU Classpath would give the same results). I believe that the GNUClasspath AWT is the cause of any visual/behavioural discrepancies I see when running Odonata on SableVM (and GIJ) and on Sun's 1.4.2 Java2 SDK. Hi, Good work! On a related note, I develop Odonata against Sun's 1.4.2 Java2 SDK and make use of the -Xbootclasspath/p feature to prepend my classes ahead of the JVM's own classes so that mine will be loaded in preference to any default ones. With SableVM I had to resort to extracting my jar file *over* SableVM's core classpath installation. This is due to the bootclasspath argument in SableVM seemingly not being able to take more than one path. Ideally, Sun-like arguments to override, append or prepend to the bootclasspath would be highly beneficial. Yes, this functionality is currently not in SableVM. In case you or some SableVM developer is interested, it should be relatively easy to change the code in: function _svmh_bootcl_internal_load_class_file in file src/libsablevm/class_loader.c to parse the boot class path property for multiple paths. This will allow an override but with multiple paths. Ex: your_path:sablevm_boot_classpath The next step will consist of playing with src/sablevm/sablevm.c to add append, prepend options.

darwin / OS X support - revisited
Hi, Chris Hoffmann from the JikesRVM team sent a patch some time ago for Mac OS X support. (see: http://mail.gnu.org/archive/html/classpath/2003-10/msg00032.html) I adapted his work to suit more the target native framework. Basically, what I did is: 1) Copy the Linux target directory to a Darwin directory. (Darwin is the name of the Unix system under Mac OS X). 2) Modified configure.ac/Makefile to use it. Note: The diff between Darwin and Linux are quite small, basically 2 lines but I still added a arch. Note: I am not a Darwin/OS X expert by the way. From the original patch: +#if (defined( __BIG_ENDIAN__) defined( __APPLE__ )) +#define __IEEE_BIG_ENDIAN +#endif + + I did not use that. I simply set CPPFLAGS as -D__PPC__ -D_BIG_ENDIAN when compiling and leave that file untouched. It may be tempting to add a __APPLE__ beside the __AIX__, but __PPC__ is not defined by gcc and we still need the CPPFLAGS anyway. Unless we do a completely separte #ifdef __APPLE__... not under the #ifdef __PPC__. - INIT_FIELD (in, 0); - INIT_FIELD (out, 1); - INIT_FIELD (err, 2); + INIT_FIELD (in, ((long long)0)); + INIT_FIELD (out, ((long long)1)); + INIT_FIELD (err, ((long long)2)); I did not do that part either. Seem to work fine. +#ifndef O_SYNC +#undef TARGET_NATIVE_FILE_FILEFLAG_SYNC +#define TARGET_NATIVE_FILE_FILEFLAG_SYNC O_FSYNC +#endif Here the problem is that O_FSYNC is be defined in fcntl.h. However, fcntl.h is not included for the constant in the generic file. On Linux works fine, OS X don't like it. So either the Linux fcntl.h gets included by some other include etc. Would need investigation. What I did, is to add a #include in the Darwin specific target file. Finally, for: +#ifdef __MACH__ +typedef intsocklen_t; +#endif I simply added it (without the #ifdef) to the network target specific file.

small compilation problem fix
Hi,
Small bug fix. Some gtk code does not compile since it is
not official C standard code: variable declaration after statements.
The patch attached fixes it.
FYI, we just updated SableVM ( http://www.sablevm.org/ ) with a yesterday
Classpath CVS snapshot in our staging branch.
http://devel.sablevm.org/wiki/Getting for info on how to get it.

Actually, not really, I'm getting about the same Mauve results on both
my platforms now (x86 and ppc). So ignore my previous comments.
BTW, I tested your code on Linux/ppc and it worked. So, it may be sparc

patch ZipFile
Classpath developers,
The SableVM developers are moving to Classpath 0.06. I will start
sending bug fixes found in Classpath.
The first one is in ZipFile. See patch included.
The current Classpath implementation removes the path component
from the name when the JarFile is created with new ZipFile(new
File(name)).
Sun's JDK does not remove the path, getName() always return the name
specified in the constructor of ZipFile or File.
(Without this fix, it is impossible to load jar files with the
SystemClassLoader that are not located in the current directory).

File.list()
Hi,
This may be some trace left from a old bug.
File: java/io/File.java.
A long time ago, there was a bug with listInternals as it was
not returning an empty array for no files. This has been
fixed since then and listInternals returns only NULL on error.
If there are no files, it correctly returns a String array
of length 0.
The current implementation of Filelists is as follows:
-
public String[] list (FilenameFilter filter)
{
checkRead ();
// Get the list of files
String list_path = PlatformHelper.removeTailSeparator(path);
File dir = new File(list_path);
if (! dir.exists() || ! dir.isDirectory() ) return null;
String files[] = listInternal(list_path);
-- if (files == null)
-- return new String[0];
if (filter == null)
return files;
Note: From the current implementation of listInternal, it will return NULL
only on error, and it will correctly return new String[0] if
the directory is empty. (I checked with gdb to make sure).
So, I suggest something like:
if (files == null) {
throw new IOException(Unknown IO Exception);
}
I am assuming some JCL_* functions set exceptions on errors (did not study
them) but this may get other exceptional cases.
Let me know if it makes sense.

Maybe Etienne could answer your questions on these. java_io_File.c: Basically, it frees a local ref, I guess otherwise it may run out of local refs for a long directory listing.

In the next few days / weeks, I will start giving some feedback to the Classpath team. (I couldn't wait to announce it!) Most work is currently done. As a test, I was able to run Ant with SableVM / Classpath 0.06 to build successfully SableCC. People interested in using/testing SableVM/Classpath 0.06 may get it from the SableVM svn repository. Note that it is still experimental. It will get much stable in the next few weeks. It is located in: /developers/belanger/sandbox/sablevm-classpath/ Info on how to access the svn repository is here: http://sourceforge.net/mailarchive/forum.php?thread_id=2629744forum_id=4154 SableVM is built as before. Look at /developers/belanger/sandbox/sablevm-classpath/bin/build_classpath to know how to build classpath for SableVM.
