This header doesn't seem to be used outside the server tree, so I don't
think anything was depending on these except what I've fixed in this
patch.
FORCE_ROOT is not used anywhere, and never has been in all the history
that's in git. ajax removed its FORCE_WIN and FORCE_CMAP companions
three years ago, in 04b87d6dfa.
BREAK_IF and IF_RETURN expanded to exactly the keywords in their names,
which is silly. They were rarely used and served only to make callers
inconsistent with the idioms used elsewhere in the server.

itself, but all library functions are prefixed by XTest. Same with the

- Rename all *Xtst* functions to *XTest* for consistency with the library
and in-server API.
- Rename the "Xtst device" property to "XTEST device" for consistency with
the extension naming.
- Rename the device naming to "<master device name> XTEST device". The
default xtest devices become "Virtual core XTEST pointer" and "Virtual

isMaster is not enough as long as we differ between master pointers and
keyboard. With flexible device classes, the usual checks for whether a
master device is a pointer (currently check for ->button, ->valuators or
->key) do not work as an SD may post an event through a master and mess this
check up.
Example, a device with valuators but no buttons would remove the button
class from the VCP and thus result in the
IsPointerDevice(inputInfo.pointer) == FALSE.
This will become worse in the future when new device classes are introduced
that aren't provided in the current system (e.g. a switch class).
This patch replaces isMaster with "type", one of SLAVE, MASTER_POINTER and
MASTER_KEYBOARD. All checks for dev->isMaster are replaced with an
IsMaster(dev).

A XTest virtual slave device pair (kbd/ptr) exists for every master
device pair. This is so XTest events are correctly propogated via slave
devices up to Master devices and the classes are correctly changed along
the way. We add the XTest slave device pair to the Virtual Core pointer
and provide a simple way of creating the devices.
A XTest Slave Device is identified by the XTstDevicePrivateKey property
being set in the devices devProperties
XI events are still propagated through the matching device, in the hope the

Previously, three extensions were defined as "trusted" by the extension:
BIG-REQUESTS, XC-MISC, and XPrint. No other extensions were permitted
to be used by untrusted clients.
In commit 8b5d21cc1d this was changed for
some reason. Return to the old, compatible behavior.
The POINTER_SCREEN flag must be set explicitly for XTest core events to avoid
out-of-range events when the lastSlave was an SD with an explicit axis range.
Device events sent through XTest don't need this flag, they are expected to be
in the valuator range of the device anyway.

The masks were originally designed to generically handle event masks for

Requires libselinux 2.0.79 or newer. Without this, libselinux will
check for policy updates on the netlink socket on basically every policy
lookup. Statistically speaking, they never happen, and the check
translates to at least one more syscall on basically every operation.
Instead, take control of the fd from the library, and check it in
WakeupHandler if it polls readable.
dixLookupResource attempted to automatically detect whether the caller
wanted a lookup by-type or by-class, unfortunately, it guessed wrong for
RT_NONE. Instead of trying to make the guess better, this patch just reverts
the unification and creates separate functions for each operation.
