Yes.
That was stupid. :(

Thanks, Chris!

Hi Christoph,

The testing looks good.
These are the results:
  http://java.se.oracle.com:10065/mdash/jobs/sspitsyn-clanger-JDK-8193258-20171212-0054-7258

The job includes hs-tier's from 1-5.
There are some failures there but nothing related to the JDI or JDWP tests.

Thanks,
Serguei

I'll submit a mach5 job to make sure nothing is broken.

Hi Serguei, Chris,

 

please look at this webrev: http://cr.openjdk.java.net/~clanger/webrevs/8193258.2/

 

I spotted a few other locations in libdt_shmem where JDWP HEADER SIZE should be used. Builds and tests running…

 

Best regards

Christoph

Hi Serguei,

 

I wasn’t aware that the jdk/com/sun/jdi tests would test libjdwp, I just found hotspot/jtreg/serviceability/jdwp when searching for jdwp in the tests. But thanks to your hints I know better now. In fact I ran the jdi tests when testing my change for 8193183.

 

I made a new webrev which includes the removal of inStream_endOfInput: http://cr.openjdk.java.net/~clanger/webrevs/8193258.1/. Can you please approve this.

 

This time I ran the jdi tests without issues and also did builds on Windows, linux x86, AIX, Solaris and Mac. J

 

Best regards

Christoph

Hi Christoph,

You need to run at least the jdk/com/sun/jdi tests.

Thanks,
Serguei

Hi Serguei,

 

I did only run hotspot/jtreg/serviceability/jdwp, didn’t find a lot more in that area. I’m hoping/waiting for Chris’ tests then.

 

I agree, I will then remove inStream_endOfInput. If something like that is needed for future developments, it can easily be added again.

 

 

Best regards

Christoph

Hi Christoph,

The fix looks good to me.
What tests did you run?

Hi,

 

Here’s a proposal to clean up the usage of the JDWP header size within the source code of libjdwp.

 

Bug: https://bugs.openjdk.java.net/browse/JDK-8193258

WebRev: http://cr.openjdk.java.net/~clanger/webrevs/8193258.0/

 

As for inStream.c, I’m wondering wether inStream_endOfInput shall be removed? It seems to be unused…


I'm inclined to remove it.
Otherwise, it must be:
  417 return (stream->left <= 0);

Thanks,
Serguei
 

Best regards

Christoph
