libXfont has stubs for these symbols, so, when compiling with hidden
symbols by default, these symbols must be visible in the X Server, or
the stubs in libXfont will be used.
I merged the wrong patch. See correct patch at:

Not activating the device before attempting to enable it would leave the
sprite unset, crashing the server when enabling the real devices.

This prevents a protocol visible side-effect (XVisibilityEvent) on
XCompositeRedirectWindow() followed by a XCompositeUnredirectWindow().
The problem shows up in gnome-screensaver with compiz and "unredirect
fullscreen windows" enable. A VisibilityNotify event is generated (first
with obscured and than with unobscured) when the window swithces from
redirected to unredirected.

As proposed by Owen Taylor [1], the enter-leave event model needs to adjust
the events sent to each window depending on the presence of pointers in a
window, or in a subwindow.
The new model can be summarised as:
- if the pointer moves into or out of a window that has a pointer in a child
window, the events are modified to appear as if the pointer was moved out of
or into this child window.
- if the pointer moves into or out of a window that has a pointer in a parent
window, the events are modified to appear as if the pointer was moved out of
or into this parent window.
Note that this model requires CoreEnterLeaveEvent and DeviceEnterLeaveEvent to
be split and treated separately.

FirstPointerChild: Return the first child that has a pointer within its
boundaries.
FirstPointerAncestor: return the first ancestor with a child within its
boundaries.
These are required for the updated enter/leave model.

Device events always need to be delivered, core events only in some cases.
Let's keep them completely separate so we can adjust core event delivery.

We need them for each window, every time a window is allocated. Storing them
in a devPrivate is the wrong thing to do.
This also removes the unused ENTER_LEAVE_SEMAPHORE_ISSET macro.

grab == devgrab anyway, this is a leftover from the time when we had two
different grabs per device (core and XI grab).
Signed-off-by: Peter Hutterer <peter.hutterer@redhat.com>
Really, this was a bad idea. It's not security, the UI features that would
have been cool (e.g. clicking through windows) aren't implemented anyway, and
there's nothing you can't achieve just by using plain XI anyway.
Requires inputproto 1.9.99.6.
EnableDevice and DisableDevice both change the property too.
And enabled must be set to FALSE in AddInputDevice, the device is not enabled
yet.
X.Org Bug 18111 <https://bugs.freedesktop.org/show_bug.cgi?id=18111>
dev->enabled is a Bool. Bool is two bytes.
BOOL on the other hand is a protocol type and always 1 byte. So copy the value
into the one-byte type before passing it into XIChangeDeviceProperty.

X.Org Bug 18111 <http://bugs.freedesktop.org/show_bug.cgi?id=18111>
The current code exposes to inconsistent updates, i.e. if handler N succeeds
but handler N+1 fails in setting the property, an error is returned to the
client although parts of the server now behave as if the property change
succeeded.
This patch adds a "checkonly" parameter to the SetProperty handler. The
handlers are then called twice, once with checkonly set to TRUE.
On the checkonly run, handlers _MUST_ return error codes if the property
cannot be applied. Handlers are not permitted to actually apply the changes.
On the second run, handlers are permitted to apply property changes.
Errors codes returned on the second run are ignored.
For two axes [a, b] and [x, y] (inclusive), the formula to scale point P(ab)
to (x,y) is:
(P - a)/(b - a) * (y - x) + x
And the whole end result rounded of course to get the integer we need.
It's not especially obvious, and unpleasantly overloaded for the Xnest
case. Typically this gives you a server that looks for its auth data in
the authority file you were using for the running X session, which
generally doesn't have an entry for the display you just started.
All the major dm's, and startx, pass -auth explicitly, so this shouldn't
cause too much upheaval.
A property can only be deleted if any of the following is true:
- if a property is deletable and all handlers return Success.
- if a property is non-deleteable and the all handlers return Success AND the
delete request does not come from a client (i.e. driver or the server).
A client can never delete a non-deletable property.
Now that the code has been fixed so that Unmap means unmap and not "don't
remap", 'remap' was confusing to have in the function names/parameters, so
change it to simple 'map'.
Signed-off-by: Keith Packard <keithp@keithp.com>
Since ReparentWindow() does a unmap/map pair for windows that are already
mapped, for saveset windows with SaveSetUnmap, we must unmap the window
before calling ReparentWindow() to avoid the generation of MapRequest
events, and so forth.
For master devices, the ptraccel code could segfault on free since we'd be
dereferencing random memory. Callocing the valuatorClassRec is the easy fix.
This removes yet another xalloc() each server generation. Also, I
couldn't find the corresponding xfree() so I guess that used to be a
memory leak there.
Two corrections
1. the "detail" field has NotifyVirtual, etc., not the "mode" field. This was
a clear bug.
2. don't set/unset the flags for NotifyGrab or NotifyUngrab. Clients are
expected to deal with multiple enter/leave events per window if the mode is
not NotifyNormal.
Testable with TCL menu boxes (such as used in gitk):
tk_optionMenu .menu globVar Val1 Val2 Val3 ValJunk
pack .menu
Thanks to Michel Dänzer for pointing this out.
Unplug a mouse, then warp the pointer and the warp pointer code will try
to update the position of the last slave device associated with the
master. That pointer will be stale and the X server will crash.
