Re: RFR (S): 8193258: Better usage of JDWP HEADER SIZE

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 On 12/11/17 11:10, serguei.spit...@oracle.com wrote: Hi Christoph, The fix looks good to me. I'll submit a mach5 job to make sure nothing is broken.

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.

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   From: serguei.spit...@oracle.com [mailto:serguei.spit...@oracle.com] Sent: Freitag, 8.

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
