Keith Packard 52048ce29f Xext/saver: Swap ScreenSaverSuspend 'suspend' field. Handle old XCB clients.
This field was defined as a Bool in the protocol headers and BOOL in
xcb. Bool is not a valid type for protocol fields. It is defined as
'int' by Xdefs.h, which we expect to be 32-bits on all machines.

The protocol headers and xcb have patches posted to switch to CARD32,
which is at least well defined.

This change adds the necessary byte swapping to handle other-endian
clients with this 32-bit field, and then changes the request
processing to compare all 32-bits against zero so that it works with
both new and old clients.

On MSB machines, Xlib will continue to work properly, but old XCB will
not interoperate with the X server (either before or after this patch).

Eric Anholt e0f872207a sync: Convert from "CARD64" to int64_t.
The extension was using the name CARD64 to represent 64-bit values,
with a #define from CARD64 to XSyncValue, a struct with a pair of
32-bit values representing a signed 64-bit value.  This interfered
with protocol headers using CARD64 to try to actually store a
uint64_t.  Now that stdint.h exists, let's just use that here,
instead.

v2: Fix alarm delta changes.

hasn't been built yet.  The unit tests are also not done.

The intent is to build this as a complete replacement for the

to generate the build, faster to run the bulid, shorter to write the
build files in, and less error-prone than autotools.

Aaron Plattner 92b3cd3206 xace: Fix XaceCensorImage to actually censor the right part of the image
The caller passes arguments into XaceCensorImage that are in
window-relative coordinates. However, the pBuf that it uses to construct
a temporary pixmap has its origin at (x, y) relative to the window in
question. The code to convert the censor region into boxes adjusts for
the Y coordinate, but leaves the X coordinate alone. The result is that
if x is not zero, it censors the wrong part of the image.

Fix this by just translating censorRegion into pixmap-relative
coordinates and using the resulting boxes as-is.

Adam Jackson 4f8a72034c res: Simplify QueryClientPixmapBytes
I suspect this code predates the common resource hooks for computing
sizes.  It's ugly in any case since the Resource extension shouldn't
need to know which extensions can take a reference on pixmaps.  Instead,
let's just walk every resource for the client and sum up all the pixmap
bytes that way.

This might be slightly slower since we're calling the size func once for
every resource.  On the other hand, it might be slightly faster since we
only walk the resource table once instead of 3-5 times.  Probably a
wash, and not really a performance path in any case.

XID may be either 'unsigned long' or 'unsigned int' depending on:

typedef unsigned long CARD64;
typedef unsigned int CARD32;
typedef unsigned long long CARD64;
typedef unsigned long CARD32;

typedef unsigned long XID;
typedef CARD32 XID;

so when building with -Wformat, we get some warnings that are benign.  This silences them.

Adam Jackson f10f36d91d damageext: Xineramify (v7)
v7: Don't bother making resources for the backing listeners. [keithp]

This is now slightly unlike how other resources are xineramified.  We
create N+1 internal damage listeners, one that's a real resource and
reflects the protocol view, and then one per backend screen where the
report function piles onto the protocol view.  The internal listeners
are not stored in the resource database directly, they just hang off the
xinerama resource. We don't wrap Subtract at the dispatch level, but we
do extend it for the Xinerama case to clip to the root window geometry.

As a result of the N+1 design here, the damage reports we generate are
not quite minimal.  However they are indistinguishable from sequential
rendering events happening before the client hears damage, and we don't
need to add a post-dispatch callback just for this one extension.

Add is probably (still) somewhat broken since it will only hit screen 0,
but Add really only exists for DRI1's sake, and DRI1 disables itself
with Xinerama enabled anyway.  In the absence of a use case, I'm leaving
it unwrapped under Xinerama; if someone wants to define how it ought to
work, be my guest.

Peter Hutterer f36f5a65f6 sync: fix corner-case in triggering idle alarms
ProcessInputEvent() resets the device idle times. If idle time was higher than
the lower bracket, this should trigger an event in the idle time wakeup
handler.

If processing is slow, the idle time may advance past the lower bracket
between the reset and the time the BlockHandler is called. In that case, we'd
never schedule a wakeup to handle the event, causing us to randomly miss
events.

Ran tests with a neg transition trigger on 5ms with 200 repeats of the test
and it succeeded. Anything below that gets a bit tricky to make sure the
server sees the same idle time as the client usleeps for.

Peter Hutterer 2523a445a0 sync: split updating and triggering a counter up
Now that the brackets are always the nearest change points (regardless of
transition) we need to update the counters whenever we check for any updates.

Otherwise we end up with a situation where counter->value is out of date and
an alarm doesn't trigger because we're still using the value from last time
something actually triggered.

Peter Hutterer e57ec99b03 sync: always set the brackets (#59644)
The current code sets bracket_greater to the first trigger after the current
value, and bracket_less to the last trigger before the current value.

For example, the idle timer with three negative and three positive transitions
would set this:

         nt1       nt2                 nt3
|--------|------|--|------- idle --|---|--|-----> t
               pt1                pt2    pt3
bracket_less == nt2
bracket_greater == pt2

This is an optimization so we can skip code paths in the block/wakeup handlers
if the current value doesn't meet any of the trigger requirements. Those
handlers largely do a
   if (bracket_less is less than current value &&
       bracket_greater is greater than current value)
        return, nothing to do

However, unless the bracket values are updated at the correct time, the
following may happen:

                                      nt
|--------------|---------- idle ------|--------> t
               pt

In this case, neither bracket is set, we're past the pos transition and not
yet at the neg transition. idle may now go past nt, but the brackets are not
updated. If idle is then reset to 0, no alarm is triggered for nt. Likewise,
idle may now go past pt and no alarm is triggered.

Changing an alarm or triggering an alarm will re-calculate the brackets, so
this bug is somewhat random. If any other client triggers an alarm when the
brackets are wrongly NULL, the recalculation will set them this bug may not
appear.

This patch changes the behavior, so that the brackets are always the nearest
positive or negative transitions to the current counter value. In the example
above, nt will trigger a wakeup and a re-calculation of the brackets, so that
going past it in the negative direction will then cause the proper alarm
triggers.

Or, in Keith's words:

  Timer currently past a positive trigger
      No bracket values, because no trigger in range

  Timer moves backwards before the positive trigger
      Brackets not reset, even though there is now a trigger in range

  Timer moves forward past the positive trigger
      Trigger doesn't fire because brackets not set

Setting the LT bracket in this case will cause everything to get
re-evaluated when the sync value moves backwards before the trigger
value.

Peter Hutterer 06b87aa528 sync: if the idle time was reset, force alarms to trigger (#70476)
The time between the idle reset and the IdleTimeWakeupHandler to be called is
indeterminate. Clients with an PositiveTransition or NegativeTransition alarm
on a low threshold may miss an alarm.

Work around this by keeping a reset flag for each device. When the
WakeupHandler triggers and the reset flag is set, we force a re-calculation of
everything and pretend the current idle time is zero. Immediately after is the
next calculation with the real idle time.

Relatively reproducible test case: Set up a XSyncNegativeTransition alarm for
a threshold of 1 ms. May trigger, may not.

Casting return to (void) was used to tell lint that you intended
to ignore the return value, so it didn't warn you about it.

Casting the third argument to (char *) was used as the most generic
pointer type in the days before compilers supported C89 (void *)
(except for a couple places it's used for byte-sized pointer math).

    xf86i2c: add pscrn for drivers to use

    This just adds a pScrn pointer into the struct for the drivers to use
    instead of scrnIndex. Mostly scrnIndex is used for logging, but some
    drivers use it to lookup xf86Screens, so let them stash a pScrn instead.

    Removing the scrnIndex is a bit more involved and I'm not sure its worth
    the effort. Doing i2c in the X server is legacy code as far as I'm concerned.

keeps the key and value inside the hashtable structure and manages
their memory by itself. This data structure is best suited for

ht_destroy. ht_create accepts the key and value sizes (in bytes) in
addition to the hashing and comparison functions to use. When adding
keys with ht_add, they will be copied into the hash and a pointer to
the value will be returned: data may be put into this structure (or if
the hash table is to be used as a set, one can just not put anything
in).

The hash table comes also with one generic hashing function plus a
comparison function to facilitate ease of use. It also has a custom
hashing and comparison functions for hashing resource IDs with
HashXID.

Erkki Seppälä 96864bfa95 Implemented first part of XResource extension v1.2: X_XResQueryClientIds
This patch implements a part of the XResource extension v1.2 (as specified in
http://patchwork.freedesktop.org/patch/2720/ ). The request implemented is
X_XResQueryClientIds.

This patch depends on the feature introduced by
1e933665be "dix: Add facilities for
client ID tracking." .

This latest version also adds Doxygen-formatted comments and takes a better
notice of coding conventions (as in http://www.x.org/wiki/CodingStyle ).

Peter Hutterer d645edd11e Xext: Add per-device SyncCounters
Previously, we only had one idle alarm that was triggered for all devices,
whenever the user used any device, came back from suspend, etc.

Add system SyncCounters for each device (named "DEVICEIDLETIME x", with x
being the device id) that trigger on that device only. This allows for
enabling/disabling devices based on interaction with other devices.

Popular use-case: disable the touchpad when the keyboard just above the
touchpad stops being idle.

Keith Packard 9838b7032e Introduce a consistent coding style
This is strictly the application of the script 'x-indent-all.sh'
from util/modular. Compared to the patch that Daniel posted in
January, I've added a few indent flags:

	-bap
	-psl
	-T PrivatePtr
	-T pmWait
	-T _XFUNCPROTOBEGIN
	-T _XFUNCPROTOEND
	-T _X_EXPORT

The typedefs were needed to make the output of sdksyms.sh match the
previous output, otherwise, the code is formatted badly enough that
sdksyms.sh generates incorrect output.

The generated code was compared with the previous version and found to
be essentially identical -- "assert" line numbers and BUILD_TIME were
the only differences found.

The comparison was done with this script:

dir1=$1
dir2=$2

for dir in $dir1 $dir2; do
	(cd $dir && find . -name '*.o' | while read file; do
		dir=`dirname $file`
		base=`basename $file .o`
		dump=$dir/$base.dump
		objdump -d $file > $dump
	done)
done

find $dir1 -name '*.dump' | while read dump; do
	otherdump=`echo $dump | sed "s;$dir1;$dir2;"`
	diff -u $dump $otherdump
done

Alan Coopersmith 9999819601 Constify string for authorization protocol names
gcc was warning from storing string constants in a char *name field:
auth.c:64:1: warning: initialization discards qualifiers from pointer target type
auth.c:72:1: warning: initialization discards qualifiers from pointer target type
auth.c:81:1: warning: initialization discards qualifiers from pointer target type

Making the field const requires changing AuthorizationFromID to take
a const char ** pointer for the name argument which it sets to point
to the matching name entry.

Changing that argument requires changing its sole caller in the security
extension to pass the address of a const char * variable to it, which it
can do, since the only thing it does with the returned name is to pass
it back to the RemoveAuthorization function that already expects a const
char *name.

-Correctly handle failure of AddResource()

-Don't assert when data structures are corrupt.  Instead,
 use a new helper function to check for counter sync
 objects when they're expected, and warn if the type is
 wrong.

-Use the default switch label rather than reimplementing
 it.

-Re-introduce cast of result of dixAllocateObjectWithPrivate()
 to kill an incompatible pointer type warning.

-Remove comments claiming protocol updates are needed.  One
 wasn't true and the other was addressed with a xextproto

James Jones 397dfd9f87 Create/Destroy/Trigger/Reset/Query Fence Sync objs
Initial server side implementation of fence sync
objects.  Allows creation, management, and state
queries of binary state objects.  Currently they
are not very useful as there is no way to wait for
them efficiently.

The basic trigger operation added here triggers
relative to a given X screen's rendering operations.
To perform this operation, fence sync objects must
be tied to a screen.  As Aaron Plattner pointed out,
screens are identified but a drawable in X protocol,
so a drawable argument is included in
XSyncCreateFence().  The screen also could have been
specified as part of the trigger operation.  However,
it is also desireable to associate a screen with
fence sync objects at creation time so that the
associated screen's driver can allocate any HW-
specific resources needed by the fence object up
front.

Peter Hutterer 675f4a8525 Abstract valuator masks through a set of APIs.
This commit introduces an abstraction API for handling masked valuators. The
intent is that drivers just allocate a mask, set the data and pass the mask
to the server. The actual storage type of the mask is hidden from the
drivers.

The new calls for drivers are:
    valuator_mask_new()     /* to allocate a valuator mask */
    valuator_mask_zero()    /* to reset a mask to zero */
    valuator_mask_set()     /* to set a valuator value */

The new interface to the server is
    xf86PostMotionEventM()
    xf86PostButtonEventM()
    xf86PostKeyboardEventM()
    xf86PostProximityEventM()

all taking a mask instead of the valuator array.

The ValuatorMask is currently defined for MAX_VALUATORS fixed size due to
memory allocation restrictions in SIGIO handlers.

For easier review, a lot of the code still uses separate valuator arrays.
This will be fixed in a later patch.

This patch was initially written by Chase Douglas.
