[9fans] cocoa devdraw

[Russ Cox]

Thanks to heroic effort by David Jeannot,
there is a new Cocoa-based OS X devdraw that
seems to work well enough that I made it the
default even on Snow Leopard.

If you do the usual hg pull -u; ./INSTALL you'll get it.

I think the only pending Lion issue now is that
people using Xcode 4.1 don't have working threads.
I haven't tracked that down yet. I suspect the
getcontext/setcontext routines in that Xcode are
just broken.

Do you have reason to believe this is a Lion issue? I'm running
Xcode 4.1 on Snow Leopard and libthread is buggered for me,
as well (I don't currently have a Lion system to confirm it's
buggered in the same way).

No, I believe it is an Xcode 4.1 issue.
However, I don't know how to obtain
Xcode 4.1 for Snow Leopard, only Lion.
How did you get it?

I believe Xcode 4.1 has been out since an iOS 4.x release. Xcode
4.2 is still in beta as it is bundled with iOS 5 beta. There is
a strong chance that the gnu toolchain in that release could our
culprit, akin to Russ' suspect of getcontext/setcontext. It may
also be that the 4.1 release was the first one where llvm-gcc was
also an option. My other build issue is in libstdio:

Ucontext stuff was being deprecated in Leopard was my understanding and that support for it would be shoddy.

Time to roll our own? Didn't you already do this?

Thanks also to David!

Yes, as Jeff suggested, I got it through the iOS developer channel.

I did for many systems, and even did for Lion,
but then I tried the system ones and they worked well
(with Xcode 4.2).

Oh well.

I get nearly identical output on Snow Leopard with XCode 4.0.2 (see below).

BUT if I manually copy o.devdraw from $PLAN9/src/cmd/devdraw to
$PLAN9/bin/devdraw, nearly everything seems to work. The best part
(for me) is that now my acme and 9term windows work with Divvy!
Huzzah!

One downside: Dragging with the middle button down no longer seems to
work right when I have MagicPrefs enabled. It works fine without
MagicPrefs, but I can't middle drag with my Magic Mouse in Google
SketchUp without MagicPrefs. Oh well, I can turn it on and off as
needed.

Thanks to everybody who's worked on this,

Micah

I tried what mauris eriksen suggested (drop -O2 in 9c) and it now
compiles with Xcode 4.1 as well.

A big Thank You to all involved!
