[jdktools][jdwp] New JVMTI functions for Java 6
Hi, drlvm gurus
Do we have implemented the JVMTI updates for Java 6?
Since the JDWP updates depends on the JVMTI new functions.
Thanks very much.

It seems we can test on RI, I suggest commit the patch then.

I agree that we can make a little modification in jvmti.h to make JDWP
new code build, but these mock shall not used to pass the testcases
(Do drlvm gurus have a plan on JVMTI uplift?)
And it seems the current ibm vme on Harmony does not support Java6
JVMTI either (Can RI be used for testing?)
However I'd like help to test your patch and commit them. Thanks.

Re: [jdktools][jdwp] New JVMTI functions for Java 6
Posted by Sean Qiu <se...@gmail.com>.
I can build and test the patch with ibm vm and modified jvmti.h. But
1.Committer cann't build it, since there is no related function in
current jvmti.h
2. Committer cann't run the test, since our drlvm has not implemented
the function.
So the question is how can i commit the patch to our community?
My proposal is i can upload another temporary patch to update the
jvmti.h in luni module for testing. And the committer can build it and
use ibm vm to test it.
Does it make sense? Any suggestions or comments?

Re: [jdktools][jdwp] New JVMTI functions for Java 6
Posted by Sean Qiu <se...@gmail.com>.
Thanks for your help Eugene.
Take a glance at the new updates of JDWP 6, we may need these
functions in JVMTI. What i have to point out is that this list is not
an very accurate one:
jvmtiError
GetClassVersionNumbers(jvmtiEnv* env,
jclass klass,
jint* minor_version_ptr,
jint* major_version_ptr).
jvmtiError
GetConstantPool(jvmtiEnv* env,
jclass klass,
jint* constant_pool_count_ptr,
jint* constant_pool_byte_count_ptr,
unsigned char** constant_pool_bytes_ptr)
jvmtiError
GetOwnedMonitorStackDepthInfo(jvmtiEnv* env,
jthread thread,
jint* monitor_info_count_ptr,
jvmtiMonitorStackDepthInfo** monitor_info_ptr)
jvmtiError
ForceEarlyReturnObject(jvmtiEnv* env,
jthread thread,
jobject value)
(
# Force Early Return - jint
# Force Early Return - Long
# Force Early Return - Float
# Force Early Return - Double
# Force Early Return - Void
)
And these new JDWP capabilities may need related jvmti capabilites' support.
canGetInstanceInfo
canRequestMonitorEvents
canGetMonitorFrameInfo
canUseSourceNameFilters
canGetConstantPool
canForceEarlyReturn
By the way, i have tried to add GetClassVersionNumbers to our jvmti.h,
and it build and run successfully with IBM VM.

Hi,
Java 6 JVMTI features are not implemented in drlvm.
Could you please provide a list of JVMTI 6 functions that are critical
for JDWP 6?
Thanks, Eugene.

Re: [jdktools][jdwp] New JVMTI functions for Java 6
Posted by Sean Qiu <se...@gmail.com>.
For example, The new ClassFileVersion Command (17) in JDWP need to
invoke the new Java 6 jvmti function:
jvmtiError GetClassVersionNumbers(jvmtiEnv* env,
jclass klass,
jint* minor_version_ptr,
jint* major_version_ptr).
We cannot find it in the current Java 5 jvmti.h.
And the other new added commands have the same problem.

Sean, maybe list some more information may help the vm gurus to see
what are missing? :)
And if some features are missing currently, we may start from
testcases and mock functions to develop new JDWP commands.
