Re: finding all windows belonging to an application

2004-11-09 Thread Robert Currey
Probably should also keep in mind that a single application (e.g. process)
might appear to an Xserver as multiple Xclients. (I think the most common
case would be a multi-thread QT app).

I've seen this also occur for "modeless" dialogs where an app either forks
or spins a thread to handle the modeless dialog. To the Xserver, it looks
like an entirely new Xclient (new connection, new XID, etc), but the Xclient
process (in a threaded case) is the same pid.

This application does a lot of operations and I'm doing some robustness
tests... I have a test tool that can stimulate application and implies lot
of drawing. The target on which application has to run is a mobile computer
with a x86 compatible 133MHz CPU, 64 MB RAM and 256MB compactflash.

Re: Memory leaks when lots of graphical operations? [Qt/X11 3.1.1]

2004-10-14 Thread Robert Currey
Not sure how your checking memory usage either ...

Consider a simple app like ...

int main(int argc, char** argv)
{
int i;
void* b;
for (i=0; i<100; i++)
{
  b = malloc(100);
  free(b);
}
sleep(200);
}

will show memory in use during the sleep ... but this app doesn't leak.

Licensing Spirit ...

2004-08-26 Thread Robert Currey
I understand there is a history of a war about the Xfree licensing. I
honestly am not try to bait or troll with this post, so please give some
consideration to this post ...

I'm trying to figure out what the "new" xfree licensing means to
*developers* (hence the post in this venue). There seem to be three types of
scenarios that a "developer" might fall in to.

#1 ...
You are a hardware vendor wanting to provide an X11 windowing system to your
boxes. You write a ddx to your hardware.

#2 ...
You are a software vendor wanting to provide an X11 windowing system to a
platform. You write a ddx to your platform.

#3 ...
You are a "solutions" provider, and want to provide an X11 windowing system
as a part of your solution. You redistribute an existing X11 distribution as
a part of your solution.

Examples would be ...
Case #1 includes cray, sun, hp, etc ... they have traditionally used the
xorg base and write a ddx to their hardware. The contributions back to the
"community" are at their choosing. This may also include a video card
manufacturer who wants to provide a "driver" for their proprietary card.

Case #2 includes PC Xserver vendors (e.g. Hummingbird, WRQ, etc) ... they
again use the xorg base and write a ddx to their platform. Again their
contributions back are at their choosing.

Case #3 includes the "free" OS providers (aka RedHat, etc) ... they
distribute a built version of an Xserver and associated utilities.

So, can someone lay down what the "XFree" licensing means to these three
classes of "developers"?

The Xorg license is pretty clear in all three cases (e.g. do what you will,
don't claim you invented it).

>From what I can gather, much of the Xfree code also falls under the original
MIT license (unless I'm mistaken and the Xorg folks relinguished their
copyright to dix, mi, cfb, etc).

Of course there is also much code in Xfree that is *not* a part of the Xorg
tee (i.e. the xfree ddx tree).

Then there is the "programs" included in both trees (xterm, xlogo, xdpyinfo,
etc).

And let's not forget the contribs (e.g. opengl from sgi with it's own
license).

I guess all I'm looking for is a "spirit" of the latest XFree86 license
regarding the various components of Xfree86 (laywers and the courts will
battle over the legaility of whatever license is written).

Is this an accurate "spirit" then 
The "Xlib" (i.e xc/lib/*) is under "MIT" license (they hold copyright, so
their license).
The "Programs" (i.e xc/programs/xterm?xlogo?xinit etc) is under "MIT"
license (they hold copyright, so their license).
The "DIX" (i.e. xc.programs/Xserver/dix?mi?cfb?mfb?...) is under "MIT"
license (they hold copyright, so their license).
The "XFree86 DDX family" (i.e. xc/programs/Xserver/hw/xfree86) is under the
XFree86 license (whatever form the copyright holder feels free to invoke).
The "Xnest DDX" (i.e. xc/programs/Xserver/hw/xnest) is under whoever wrote
it's license (i dunno, duncare, but someone)
The "Contribs" (i.e. xc/contrib/*) are under the license of the
"contributor" ...

If that is accurate then ...
Developer #1 above can then use the Xfree86 code distro under an MIT license
(unless they utilize the xfree86 ddx code, and then they fall under that
license). Utilizing "contribs" places them under the "contribs" license as
well.
The above would be the same for developer #2. (i.e under the license of the
ddx code you base from, and the contribs you choose to use).
Developer #3 is in a murky situation to me ... but then again sort of the
same.

Again, I am not trying to bait or troll here, I just want an understanding
of the "spirit" of the license XFree86 has gone to, and how that applies to
the various components of the tree.

To play nice, this should only need xkb file interpretation changes
(changing the way the code works may get messy).
I'm not that hip on how XKB maintains "state", but for Alt-gr type combos it
is at least close.

My experience says you can never safely assume anything about x apps :)

ummm ... the  "to be transparent" is true for windows, but obviously not for
unix or mac or ...

This really smells like an input method ...so your app that needs to play
with "readers for Smartcards or keyboard-wedge style barcode readers" would
need to support the input method.
