[Libvncserver-common] Unit tests (beginnings of)

[Johannes S. <Joh...@gm...>]

Hi all,

as I mentioned earlier this year, I added libvncclient primarily to make
unit tests a reality. So, here they are! As of now, you can only use the
test if you have pthreads enabled, because the client would block when
reading from the server.

In the course I realized that I completely forgot to implement ZRLE
encoding in libvncclient, and I found out that my "fix" for CoRRE was no
fix: CoRRE is not working right now (I don't really know if it is the
client or the server, but probably the server. The problem is that not
enough updates are sent).

If you want to look at the code: test/encodingstest.c.

As always, if you find documentation missing, incomplete or just wrong,
don't hesitate to fix it ;-) Or at least to mention the problem on this
list, so that at least it's a known issue... After all: bad dox are worse
than no dox are worse than good dox.

Ciao,
Dscho
