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 From: Langer, Christoph Sent: Sonntag, 10.

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. ☺ Best regards Christoph From: serguei.spit...@oracle.com<mailto:serguei.spit...@oracle.com> [mailto:serguei.spit...@oracle.com] Sent: Samstag, 9.

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

What tests did you run? On 12/8/17 07:07, Langer, Christoph wrote: 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/<http://cr.openjdk.java.net/%7Eclanger/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
