Fully integrating xcb includes replacing the transport & multi-threaded locking mechanisms of libX11. Those interactions are complex and need to be well understood and tested. Questions off the top of my head that we need answers to: - Solaris libX11 includes supports for transport types not used on Linux & BSD, including Named Pipes (also available in upstream X.Org, but only used on SysV systems) and the SUN_SME shared memory transport (a Solaris-ism we've never gotten around to pushing upstream) - does xcb support pipes? What do we need to do to add SME support, or does this force us to drop it? - Solaris libX11 connection code also has special support for the IA process control extension that I've not gotten upstream yet - what needs to happen to xcb to make this work? - Linux distros that adopted libxcb discovered the threading changes caused Java to deadlock - how do we make sure we avoid this on Solaris? What Solaris Java versions may be affected? (Just saying "Use latest Java" doesn't help people who want to install Oracle which forces its install gui to use their bundled JRE.) http://bugs.sun.com/view_bug.do?bug_id=6532373 Are any other programs going to be similarly affected? For instance, I doubt anyone on the planet has ever run CDE with an xcb-ified libX11 before. - Is there an increase or decrease in application performance when using the xcb-ified libX11? - Our libX11 has a bunch of thread/locking changes that aren't upstream - are these still correct with libxcb? Do we need to change them? - We have several extensions that haven't been upstreamed, do we need to create libxcb xml protocol descriptions of them? > So what am I to do to accelerate this process ? Either help us do all this, or tell me why this is important to you and give me a reason to prioritize this work over the other stuff we're working on. Is this more important than finishing the migration of our old code base to current open source releases that we can publish the sources for on opensolaris.org? More important than upgrading Xorg server to 1.5.x? I can't make more people appear to do more work, and no one is sitting around here with nothing to do, so would have to ask someone to stop working on other things to work on this. -- -Alan Coopersmith- alan.coopersmith at sun.com Sun Microsystems, Inc. - X Window System Engineering
