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

[Paul Szabo]

Dear Mike,

My current patches, for BIG-REQUESTS and Generic Event Extension, below.
With these, nxproxy works well. (Though, once a crash was observed,
unfortunately not "trapped" or de-bugged, yet...)

Some other patches, that make nxproxy more useful in my environment,
below also (hoping others find them, or those ideas, useful also).

---

I compared the efficiency of the various compressors, recorded network
traffic generated when using "plain" uncompressed X11 traffic, "ssh -C",
dxpc and nxproxy, showing kBytes received and transmitted:

What                plain          ssh             dxpc            nxproxy
texworks         6828R 4816T    2342R 1240T     3050R 4718T     2535R 429T
libreoffice      2055R  199T    1205R  130T     1145R  140T     1230R 131T
matlab          51691R 1508T    2096R  311T     2122R  303T     1894R 232T
mathematica5     2508R 1004T    1473R  522T     1354R  384T     1307R 312T
mathematica9    33271R 5767T    4118R  858T     3465R 4943T     4581R 808T

and a certain youtube video in kBytes/sec (approx):
What                plain          ssh             dxpc            nxproxy
youtube          22000R  510T  16000R  300T          ?         17000R 410T

I wonder if it is worthwhile to persist with nxproxy, or maybe should
try to use "ssh -C" in some automated way.

Cheers, Paul
