Re: HARMONY-1407: Contribution of Java code for package java.lang.management
Yes. I have some docs that need to be put in SVN - I hope to do that today. Once we do that, we need to simply vote to accept the code.

[classlib][luni]A difference between Unicode4.0 and Unicode4.1 affects our implementation of j.l.Character.
Hi all, I encounter a problem when implement the method isJavaIdentifierPart(int) in j.l.Character. The Character U+200B was redefined[1] in Unicode4.1 and caused a testcase[2] failed. Our implementation is compatible with Unicode 4.1 whereas RI is compatible with 4.0. I wonder which one should we follow.

[General]Is there an agreement on different order of throwing Exceptions between RI and Harmony?
I noticed there are many JIRA issues [1] about Exception order. Some of them were fixed whereas others were marked as non-bug difference. I wonder which kind of Exception order problem should be fixed, and which type should be left as non-bug difference. Is there any agreement? I suggest setting one if not.

Re: [jira] Commented: (HARMONY-286) Add build-java and build-native targets to main build.xml
Hi Alexey, At the time I was working on native code all over the place, and since rebuilding our java classes takes a very long time on my Windows box I found it useful to be able to just build all the natives. I dont mind if this issue is closed as it's not really a major problem (also the patch is probably very out of date, although it should be fairly easy to create a new one) - however, I think it is something that is still useful, and if we can add it without much effort, then why not? As for using ant -f make/build-java.xml -Dbuild.module=awt build, I believe that we discussed a little while ago that we would try to put all main build targets into the top level build.xml, so that no developer needs to directly execute the build scripts under make. IMHO it is preferable to call ant -Dbuild.module=awt build-java in this case. If there is still interest in this feature, I can create an up-to-date patch and attach it to the JIRA.

[classlib][io][nio] Sync issue of java.io.FileOutputStream and java.nio.channels.FileChannel
Hello,
One Apache Derby test[1] fails on Harmony. It seems that RI always
sync the FileOutputStream and FileChannel after each write, which is
different from Harmony. But there is no explicit description in Java
Spec. Shall we follow RI? Thanks a lot.
The following test cases could demonstrate this issue.
public void testFile() {
File derbyLog = new File(d:\\, derby1.log);
try {
FileOutputStream fos = new FileOutputStream(derbyLog);
fos.write(0x41);
assertEquals(1, derbyLog.length());
} catch (Exception e) {
e.printStackTrace();
}
}
public void testFileChannel() {
File derbyLog = new File(d:\\, derby2.log);
try {
FileOutputStream fos = new FileOutputStream(derbyLog);
FileChannel fc = fos.getChannel();
fc.write(ByteBuffer.wrap(new byte[]{0x41, 0x42}));
assertEquals(2, derbyLog.length());
} catch (Exception e) {
e.printStackTrace();
}
}

Re: [General]Is there an agreement on different order of throwing Exceptions between RI and Harmony?
And, based on the agreement of exception-throwing compability issue, I think most those JIRAs can fall into guideline2:*Follow the Reference Implementation* Because in most situation, the order of throwing Exceptions is not restricted in spec, and almost any order is reasonable. So we can just follow RI in most JIRAs. And maybe few special cases need to be discussed.

Propose a fix then. All I was trying to do was localize the free() under windows. Besides, you introduced inconsistency in names, ones registered inside of ClassLoader::LoadNativeLibrary and those actually loaded in natives_load_library(). So, if one will try loading the same lib with different names on Windows via j.l.System.loadLibrary(), there will be unexpected UnsatisfiedLinkError. I guess that awkward usage of port_filepath_canonical() was intended to solve exactly this problem. I can't see how. Seems like port_filepath_canonical() was being used in LoadNativeLibrary() was to create a full path, and would PREPEND THE CURRENT DIRECTORY to it. So in our case, where we are wanting to let apr_dso_load() get a dll/so, it *can't* presume current directory. That said, I do agree that we should move the lower-casing done in natives_load_library() and just demand that callers get their path right as part of the API for natives_load_library() If you want to add that to your fix above, that would be great.

Re: [vmi] Extending the VMI to allow setting a default portlib
Tim Ellison wrote: Geir Magnusson Jr. wrote: Tim Ellison wrote: At present, the Harmony launcher creates and passes an instance of the portlib to the VM as it is being created (via an _org.apache.harmony.vmi.portlib init arg). This is good because allows the launcher to define functions used for memory alloc, file IO, etc. early. However, we also need to work with regular applications that are embedding the JVM, and don't know/want to set up this argument for us. In such a case the classlib should use a default portlib (and possibly JVM subsequently if it wants). This seems backwards to me. Wouldn't we want the VM use the default portlib and give that to the classlib? VMs that want to use the portlib can do that today anyway (e.g. drlvm was creating the portlib itself), so this would allow setting the portlib by the classlib where the VM doesn't care. So today, the launcher creates a portlib and passes it in as a VM property, and the VM stores the struct ptr in the VMI. I'm suggesting that we allow any one of: - VM takes the version passed in via the launcher property - VM creates a default version and puts it in VMI - classlib creates a default version and puts it in VMI This makes sense to me - it gives the most flexibility for when the port library is created. If the launcher doesnt do it, fall back to the VM. If the VM doesnt do it, fall back to the classlib default. It seems sensible to have a failsafe in place, even if we never have to use it. Regards, Oliver Regards, Tim I propose that we retain support for the init arg, but make it optional, and that we extend the VMI [1] to allow setting the portlib struct where it has not been previously defined. The portlib struct can only be defined once, subsequent attempts to set the portlib would return an error. Of course, you can still modify the struct to redefine the functions it contains. The new VMI function would be: vmiError(JNICALL * SetPortLibrary) (VMInterface * vmi, HyPortLibrary * portlib); then the early logic in JNI_OnLoad for luniglob.c [2] would become: (a) if vmInterface-GetPortLibrary(vmi) is not NULL then continue (b) otherwise create new portlib, and vmi-SetPortlib(vmi, portlib). and the corresponding JNI_OnUnload would destroy the portlib iff it had been created in step (b).

Re: [classlib][io][nio] Sync issue of java.io.FileOutputStream and java.nio.channels.FileChannel
On 9/18/06, Richard Liang [EMAIL PROTECTED] wrote:
Hello,
One Apache Derby test[1] fails on Harmony. It seems that RI always
sync the FileOutputStream and FileChannel after each write, which is
different from Harmony. But there is no explicit description in Java
Spec. Shall we follow RI? Thanks a lot.
The following test cases could demonstrate this issue.
public void testFile() {
File derbyLog = new File(d:\\, derby1.log);
try {
FileOutputStream fos = new FileOutputStream(derbyLog);
fos.write(0x41);
assertEquals(1, derbyLog.length());
} catch (Exception e) {
e.printStackTrace();
}
}
public void testFileChannel() {
File derbyLog = new File(d:\\, derby2.log);
try {
FileOutputStream fos = new FileOutputStream(derbyLog);
FileChannel fc = fos.getChannel();
fc.write(ByteBuffer.wrap(new byte[]{0x41, 0x42}));
assertEquals(2, derbyLog.length());
} catch (Exception e) {
e.printStackTrace();
}
}
Interesting. I think we'd better follow RI although it's implementation
dependent. Otherwise, it breaks existing application.
To make test more interesting, I wrote a similar test:
public void testFile() throws Exception {
File derbyLog = File.createTempFile(test, log);
derbyLog.deleteOnExit();
RandomAccessFile fos = new RandomAccessFile(derbyLog, rws);
for (int i = 0; i 1000; i++) {
fos.write(0x41);
assertEquals(1 + i, derbyLog.length());
}
}
Run it and you'll be surprised. :-)

If you are interested to participate in the development, I propose to discuss all details in this mail thread. The current state: Part of the functionality of vmmagic package is done in the magic1.patch. See JIRA 1489 (http://issues.apache.org/jira/browse/HARMONY-1489) Tasks that are not finished: 1) Support of unsigned types. 2) Support of atomic prepare/attempt operations 3) Testing suit for vmmagic package. 4) EM64T support I hope items 1) and 2) will be finished in a week or even sooner if someone helps. After it's done the item 4) won't be a problem. I think that the problem (at least for me) is item 3): we need a test suite for vmmagic package. I saw several tests in Weldon's drlvm/trunk/vm/MMTk folder, but this is not sufficient to cover the whole vmmagic package.

If you are interested to participate in the development, I propose to discuss all details in this mail thread. The current state: Part of the functionality of vmmagic package is done in the magic1.patch. See JIRA 1489 (http://issues.apache.org/jira/browse/HARMONY-1489) Tasks that are not finished: 1) Support of unsigned types. 2) Support of atomic prepare/attempt operations 3) Testing suit for vmmagic package. 4) EM64T support I hope items 1) and 2) will be finished in a week or even sooner if someone helps. After it's done the item 4) won't be a problem. I think that the problem (at least for me) is item 3): we need a test suite for vmmagic package. I saw several tests in Weldon's drlvm/trunk/vm/MMTk folder, but this is not sufficient to cover the whole vmmagic package. Does anyone know/can_write a reliability test suite for vmmagic we can use in Harmony? A regression test for vmmagic exists. I have been trying to get it donated and posted to MMTk repository. Its been a couple of months and no response. I will find out if it can be donated to Apache. -- Mikhail Fursov -- Weldon Washburn Intel Middleware Products Division

DRLVM depends on knowing where the claslibrary is because it uses

assembling the jre.
So, by default, the DRLVM assumes that it and the classlibrary are
located as follows, relative to each other :
enhanced/classlib/trunk
enhanced/drlvm/trunk
So if that relationship isn't the way it is on your machine, then you
will have problems like you see, as DRLVM looks over into classlib to
see if XALAN is there as a check.
The solution is to go :
$ cd drlvm/trunk/build
$ cp drlvm.properties.example drlvm.properties
and them modify drlvm.properties so that it finds the right classlib
root. I believe it's relative to trunk/build.
When you then type sh build.sh, it will print out the classslib

[drlvm] Jars work again, and other notes
I'm at a conference today, but in my idle bits of time, I restored the capability to do java -jar foo.jar I added a little JarRunner class to our kernel classes, but we should move this to classlib, as there's nothing DRLVM specific about it. I also had to modify the launcher to get this to work, as there's a codepath in the launcher that makes DRLVM crash hard. I've commented it out because it was just a safety check, but it would be good for us to figure out what it is. Broken windows, and all that. One thing I noticed is that we now have to set JAVA_HOME correctly. We never had to do this before, and from the stacktraces generated, I haven't a clue why. Something for someone to figure out. Anyway, I'm going to test a bit more and then do a new set of snapshots. geir - Terms of use : http://incubator.apache.org/harmony/mailing.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: [DRLVM][JIT] can Jitrino.JET call MMTk alloc() instead of C helper?
Can someone clarify what Jetrnio.JET is please ?

Weldon,
I added 'alloc' support to JIRA 816 (magic2.zip file)
Now it supports objects allocation only, not arrays. MMTk allocation
works
only for class named 'test' and methods with prefix 'testAlloc'. To
turn
it on use -Xjit jet::alloc4j option.
Thanks! I will take a look this weekend.
I had a problem with implementation: usual 'new' vm helper does vtable
field
initialization in allocated object space by itself. Your alloc() method
doesn't.
In the patch in JIRA I added vtable initialization code right after the
alloc() call to JIT, that is actually bad design decision (IMO).
You are correct. Its bad design. Writing the vtable pointer is not the
responsibility of the JIT. MMTk is somewhat vague on who owns vtable ptr
init. In any case, it looks like the jit should follow the call to
alloc()
with a call to postAlloc(). I will make sure the postAlloc() code fixes
up
the vtable ptr. Its OK to bend the typeRef. All I want is the hard ptr
that gets written into the object header. We will go back later and fix
this interface hack. See below:
/**
* Perform post-allocation actions. For many allocators none are
* required.
*
* @param ref The newly allocated object
* @param typeRef the type reference for the instance being created
* @param bytes The size of the space to be allocated (in bytes)
* @param allocator The allocator number to be used for this allocation
*/
public void postAlloc(ObjectReference ref, ObjectReference typeRef,
int bytes, int allocator) throws InlinePragma {
Can we replace the 'alloc()' call with another Java method that uses
unboxed API and behaves exactly like 'new' helper?
+The test in the patch throws NullPointerException because no memory is
allocated in alloc() now and JET tries to write vtable data by NULL
address.

That said, I agree that some hints by programmer to assist GC might be an interesting topic. There are always weak references to help out with short lived objects - you know they will be collected fairly soon (should be within a few gc cycles) - and soft references for longer lived ones.

Re: [drlvm] Trouble Building DRLVM
Geir, Thanks. I got it the DRLVM to build now, but I'm coming across problems running it. First, let me mention a couple things about the README that I found, while trying to build the VM. 1. I had to remove the revision tag (-r revision_number) for the downloading of software and tools. There were two places in the file lnx.properties where I removed svn's -r tag. Perhaps this is why I am currently having trouble running it. But without removing the -r tag, I kept getting a 'Secure connection truncated' error message, causing the build to fail. 2. Geir's comment fixed the other problem I had (i.e. change drlvm.properties to point to classlib). I should have seen this one on my own but, just for the record, I don't think there is anything in the README about this. After those two things, the build is just fine. After that, the README starts talking about ij.sh, which I don't even see in the deploy/jre/bin directory. What I do see is a file called java. I have set my LD_LIBRARY_PATH to /Harmony/enhanced/drlvm/trunk/build/deploy/jre/bin. So, here is what happens when I tried to run it: /Harmony/enhanced/drlvm/trunk/build/deploy/jre/bin./java Harmony Java launcher Apache Harmony Launcher : (c) Copyright 1991, 2006 The Apache Software Foundation or its licensors, as applicable. java [-vm:vmdll -vmdir:dir -D...

Aborted Also, if I try to run a java program it just hangs. After this, I searched the mailing list archives for this problem, and found this: http://mail-archives.apache.org/mod_mbox/incubator-harmony-commits/200608.mbox/[EMAIL PROTECTED] So, since my problem looked similar I changed the assertion, but now I get this: /Harmony/enhanced/drlvm/trunk/build/deploy/jre/bin./java Harmony Java launcher Apache Harmony Launcher : (c) Copyright 1991, 2006 The Apache Software Foundation or its licensors, as applicable. java [-vm:vmdll -vmdir:dir -D...

DRLVM depends on knowing where the claslibrary is because it uses headers and libraries from it when building, and copies stuff when assembling the jre. So, by default, the DRLVM assumes that it and the classlibrary are located as follows, relative to each other : enhanced/classlib/trunk enhanced/drlvm/trunk So if that relationship isn't the way it is on your machine, then you will have problems like you see, as DRLVM looks over into classlib to see if XALAN is there as a check. The solution is to go : $ cd drlvm/trunk/build $ cp drlvm.properties.example drlvm.properties and them modify drlvm.properties so that it finds the right classlib root. I believe it's relative to trunk/build. When you then type sh build.sh, it will print out the classslib location. if it's not right, repeat :) geir BUILD FAILED /u/u12/anavabi/Harmony_VM/build/make/build.xml:238: The following error occurred while executing this line: /u/u12/anavabi/Harmony_VM/build/make/setup.xml:289: The following error occurred while executing this line: /u/u12/anavabi/Harmony_VM/build/make/setup.xml:291: The following error occurred while executing this line:

Just comment it out since it is just a warning treated as error. It compiles successfully and runs well.

Hello,
One Apache Derby test[1] fails on Harmony. It seems that RI always
sync the FileOutputStream and FileChannel after each write, which is
different from Harmony. But there is no explicit description in Java
Spec. Shall we follow RI? Thanks a lot.
The following test cases could demonstrate this issue.
public void testFile() {
File derbyLog = new File(d:\\, derby1.log);
try {
FileOutputStream fos = new FileOutputStream(derbyLog);
fos.write(0x41);
assertEquals(1, derbyLog.length());
} catch (Exception e) {
e.printStackTrace();
}
}
public void testFileChannel() {
File derbyLog = new File(d:\\, derby2.log);
try {
FileOutputStream fos = new FileOutputStream(derbyLog);
FileChannel fc = fos.getChannel();
fc.write(ByteBuffer.wrap(new byte[]{0x41, 0x42}));
assertEquals(2, derbyLog.length());
} catch (Exception e) {
e.printStackTrace();
}
}
Interesting. I think we'd better follow RI although it's implementation
dependent. Otherwise, it breaks existing application.
To make test more interesting, I wrote a similar test:
public void testFile() throws Exception {
File derbyLog = File.createTempFile(test, log);
derbyLog.deleteOnExit();
RandomAccessFile fos = new RandomAccessFile(derbyLog, rws);
for (int i = 0; i 1000; i++) {
fos.write(0x41);
assertEquals(1 + i, derbyLog.length());
}
}
Run it and you'll be surprised. :-)
Wow! It tooks RI 0.381 seconds, while 21.761 seconds for Harmony. We
shall improve our performance!
Let's have a more further study about this issue.
