[app] ant with ecj
Hi all. I'm trying to use ant with the ecj compiler. I override the compiler in build.xml like this: property name=build.compiler value= org.eclipse.jdt.core.JDTCompilerAdapter / This will execute the compiler, but I find I have to add each jar from jdk/jre/lib/boot to CLASSPATH or else ecj won't find the standard classes during compilation. This is probably user error, and not related to harmony. :) Does anyone know what I might be improperly configuring? Thanks, -Jordan

I take it that means the issue is pretty obvious (very easy to recreate).

Re: [app] ant with ecj
Hello Jordan,
All the boot jars have been add in the javac tasks. Could you please
paste the stack trace? Thanks a lot.
Please refer to modules/luni/build.xml
javac
bootclasspath
fileset dir=${hy.jdk}/jre/lib/boot
include name=**/*.jar /
/fileset
/bootclasspath
Best regards,

Nathan,
Is there a way to have the javac/ecj task include all of standard harmony
jars without including them in the CLASSPATH environment variable?

Keep in mind that the execution of the Ant scripts and the
compilation are
two separate things, which means they are using two different
classpaths.
If
the compilation task is complaining about a missing class, then this
means
the class is missing from the classpath of the compiler, not the
classpath
of the executing Ant. You'll need the Eclipse compiler JAR on Ant's
execution classpath to execute the javac task.
This can be confusing when using the Eclipse compiler, since it doesn't
have
any default classpath. Normally when you're using 'javac' from a JDK,
the
classpath of the underlying JRE (all of the java.*, etc classes) is
automatically on the classpath. The Eclipse compiler is not part of a
JDK,
so there is nothing on the classpath by default.

Subject: Re: [app] ant with ecj
Richard,
Yes, I also added ecj_3.2.jar to the CLASSPATH.
Ant works fine, but the first time a javac task is encountered, the
compiler
complained that java.lang.Object was not found. I then added
jdk/jre/lib/boot/kernel.jar to CLASSPATH. Now, I see an error that
java.lang.String is not found, so I added luni.jar to CLASSPATH.
etc...
Since ant is basically working (mkdir tasks, delete tasks, java tasks
all
seem to work), I think the harmony jvm is loading these boot
jars, but
it
seems like when the javac task uses ecj, those jars are not visible.
I'm using windows xp, ant 1.6.5, and the latest harmony jdk snapshot.
Thanks again,
-Jordan

Hello Jordan,
Do you mean the build.compiler property in make/build_java.xml? I
just
give it a try by 1) overriding the compiler as what you have done 2)
adding C:\harmony\workspace\trunk\depends\jars\ecj_3.2\ecj_3.2.jar
into
classpath.
Everything works OK. :-) Could you give more detailed information
about
this issue? Thanks a lot.

Could you please take a look? Thanks, Mikhail Hi Mikhail, You are right. Two of these four tests are due to typos in the exception messages: 1)org.apache.harmony.tests.java.math.BigDecimalConstructorsTest.testConstrStringExponentIntegerMin( BigDecimalConstructorsTest.java:497) expectedScale out of range. but was Scale out of range 2)org.apache.harmony.tests.java.math.BigDecimalScaleOperationsTest.testMovePointRightException( BigDecimalScaleOperationsTest.java:335) expectedUnderflow but was UnderFlow We corrected them (and a similar problem with Overflow) with a new patch typos.diff.zip´ in H1208. The other two failing tests require some discussion. 3)org.apache.harmony.tests.java.math.BigDecimalConstructorsTest.testConstrBI(BigDecimalConstructorsTest.java:75) I believe the test is wrong in this case since according to the API specification the NullPointerException will actually be thrown before the try block. The test incorrectly expects it to be thrown in the block. The RI also fails this test. I've just rerun it on RI and it passed. What RI version do you use? I got the argument about the spec. It in a class description, right? Right. The description of the class BigDecimal contains the statement All methods and constructors for this class throw NullPointerException when passed a null object reference for any input parameter. Thus, there is a bug in the 1.5.0 version of the RI when invoking the constructor BigDecimal(BigInteger val) with a null argument since it does not throw NPE. This bug is fixed in version 1.5.0_08 (and also in 1.6). I have just seen in H784 that Vladimir Ivanov discovered this for version 1.5.0_06. 4)org.apache.harmony.tests.java.math.BigDecimalArithmeticTest.testDivideByZero(BigDecimalArithmeticTest.java:492) expected BigInteger divide by zero but was Division by zero This is not just a typo. Both exception messages are used by the RI in different BigDecimal.divide methods when dividing by BigDecimal.ZERO. There is at least a third message: / by zero. Some methods seem to use different messages depending on the size of the dividend. So, I see two possibilities here: a) use everywhere the message Division by zero. b) try to find out when RI uses each of the different messages. I would suggest a) rather than b) since from the point of view of the programmer it is reasonable to obtain the same message when dividing by BigDecimal.ZERO regardless the size (or internal representation) of the dividend and the method invoked for the division. In general if a programmer use only one method in their implementation where RI throws BigInteger divide by zero, then they are not aware of other exception messages and they might hard code that BigInteger divide by zero one. It is a bit more complicated than that. From the tests we have run we can naturally guess that there are two groups of BigDecimal.divide methods in RI: i) those which check if the divisor is BigDecimal.ZERO in which case they throw the exception with the message Division by zero. ii) those which do not check (forget to check?) and attempt to divide anyhow: they will use the BigInteger divide by zero or / by zero depending on where the problem happens. That is, depending on whether the dividend is large (and the division takes place in BigInteger) or small (and the division takes place in a primitive type). So I'd prefer to keep it look like RI as it is now. BUT, if this change implies an undesirable design change then I'm OK with discrepancy in exception messages Keeping it look like RI for methods of group ii) would imply trying to determine the exact border between messages BigInteger divide by zero and / by zero. Thanks Daniel Thanks, Mikhail In addition, doing b) may imply inspecting the behavior of RI a bit too far. I am reluctant to do this since different messages may reveal when the unscaled value is implemented as a BigInteger and when as a primitive integral value. We submitted a new patch tests.diff.zip to H1208 correcting the test mentioned in 3) and replacing the test in 4) by another invocation to divide with the Division by zero message. Both RI and our implementation pass the tests. I think both patches should be applied. In the meantime we may discuss if the approach b) is preferred.

Re: [drlvm] how does drlvm insert the safe point into a method
Hi Fan, I think you are asking about safe instruction pointer addresses in JITed code where the JIT is able to enumerate all live references. If this is the case, it turns out there are lots of subtle interactions between all the pieces of the system. In otherwords, I can't do justice to the topic in an email. But I will point you in the right direction. The JIT can insert polling code at points where it knows it can find all live references on a thread's stack. When the GC wants a thread to suspend and report its live references, it can set a flag in the thread-local context. When the JITed code sees the flag set, it will suspend the thread and report the live references. As far as I know the DRLVM JIT you are looking at does not quite do this yet. An incomplete but useful for bringup approach is to let the targetted thread continue executing until it tries to allocate an object. Assuming there is no space available, the thread is vectored into the garbage collector itself. By design, object allocation sites are places where the JIT can enumerate all live references on the stack. There are other schemes, such as suspending and resuming the targetted thread until the JIT reports it can enumerate. I won't bore you with the details here. Let me know if this helps. On 8/27/06, Fan Bin [EMAIL PROTECTED] wrote: Hi, I have a question about jit compiler in drlvm. I want to suspend the thread manually on a particular point. I know that the thread can only be suspended at safe point. I guess the safe point is inserted by jit compiler when it compile the method, but I can't prove it from the source code. So my question is whether it's true that it is the jit compiler which insert the safe point. If it is true, how does it do this?
