[pkg-x2go-devel] Bug#766299: nxproxy: BIG-REQUESTS patch builds but fails at runtime

[paul.szabo at sydney.edu.au]

Dear Mike,

Could you explain to me, or point me to some documentation, about the
use of sequence numbers in X11 generally, and in nxproxy specifically?
Even more specifically, as noted in my latest patches:

ClientChannel.cpp:
       // With outputOpcode=X_UnmapSubwindows mostly we get sequenceNum=0,
       // sometimes (rarely) get sequenceNum = 256. Maybe surprising, but
       // "normal" and should be accepted.

ServerChannel.cpp:
       // We normally get inputSequence=0 for inputOpcode=X_UnmapSubwindows

Should nxproxy "accept" those zeroes, or should it handle them in some
special way? Do any other opcodes reply with a zeroed sequence number?

Am I on the wrong track, barking up the wrong tree?

Thanks, Paul
