*Background*
Patch 120094-22, may cause performance degradation of CPU and system
become unresposive when Trusted Extension or Accessibility is turned
on. Fixes of CR 6769901 are not appropriate should be corrected with CR
6839026, on all the x86 and SPARC machine .
When a machine is patched with 120094-22, Symptoms are as follows.
a) When screen is locked and Accessibility is turned on, popup window
might make x86/SPARC machine unresponsive.
b) When screen is locked and Trusted Extension is turned on, may cause
performance degradation of CPU. [tx] Xsun chews cpu and console appear
to be hung.
*Questions*
Q:why we have not fixed it at WindowManager?
Ans: We got some success in fixing this bug at metacity/WM, but with
lots of code changes. Login helper interface is required at metacity
Q: Is it fixed completly .What is remaining?
Ans: Yes this bug is fixed completely. But we should wait for final
test results, if any problem comes we will fix in CR6875930.
There are some special cases, where we need to do restacking of pop up
windows in timer.c . Also there are some existing bugs in a11y, we will
address them separately.
We are fixing this bug in incremental mode, all the remaining problem
will be fixed in CR6875930
*What we have fixied*
Xsun is consuming 100% cpu cycle with trusted path because of CR6769901
Also we found, with accessibility, cpu consumption goes to 100%
Popup window should not come through screensaver.
*Testing *
a) Pop-ups will not come through screensaver in case of dual head
display with and without xinerama . Same is the case when a11y is turned on.
b)Pop-ups will not come through screensaver with twinview display of
Xorg. Also there will be no performance degradation with my fixes
c) Pop-ups will not come through screensaver with trusted path
d) Pop-ups will not come through screensaver with all a11y cases
e) works fine with Xnewt,Xorg and Xsun
f) works fine with x86, x64, SPARC
g) The only pop-ups to get through are the ally pop-ups which are
allowed by design. GOK and MAG always on top of screensaver when we
lock the screen.
I am including svn diff of repository trunk/vermillion. For more detail
please see the attached source file.

Need to update about SUBCR of Nevada #6839026
My new fixes are very stable now. Barun and I have tested it very
thoroughly with a11y on. Today I will raise it for JDS-Review, if no
objection from Jeremy and Alan.

core pointer mode"
*
* ScreenLock did not unlock the screen, but WM's XRestackWindow() did.
* Once WM/metacity fixes the problem, the code can be removed.
The problem:
repositioning the Wids in the wrong positions when
1. the window type is changed from NORMAL to DOCK or vice versa
2. the Wid is managed
within the X window stack with or without screen-lock in a mixed Wids
there are two temp. get-around solutions:
1. non-managed GOK or MAG Wid
or
2. screensaver picks up the WM's restacking task and fixes the prevous
restacking problem.
the cons: there is a flashing screen when corepointer is touching
GOK or MAG and mouse is moved in a fast way
when GOK or MAG window type is DOCK only.
and it is not a good temp. get-around solution.
This is the only choice if WM did not want to fix the problem now
and AT group did not want to use non-managed Wids.
Now, GOK only supports 2nd USB/mouse/Dwell, corepointer is supposed
not to be used, and GOK cannot disable it

Need to update about SUBCR of Nevada #6839026
My new fixes are very stable now. Barun and I have tested it very
thoroughly with a11y on. Today I will raise it for JDS-Review, if no
objection from Jeremy and Alan.
*Background*
Patch 120094-22, may cause performance degradation of CPU and system
become unresposive when Trusted Extension or Accessibility is turned
on. Fixes of CR 6769901 are not appropriate should be corrected with CR
6839026, on all the x86 and SPARC machine .
When a machine is patched with 120094-22, Symptoms are as follows.
a) When screen is locked and Accessibility is turned on, popup window
might make x86/SPARC machine unresponsive.
b) When screen is locked and Trusted Extension is turned on, may cause
performance degradation of CPU. [tx] Xsun chews cpu and console appear
to be hung.
*Questions*
Q:why we have not fixed it at WindowManager?
Ans: We got some success in fixing this bug at metacity/WM, but with
lots of code changes. Login helper interface is required at metacity
Q: Is it fixed completly .What is remaining?
Ans: Yes this bug is fixed completely. But we should wait for final
test results, if any problem comes we will fix in CR6875930.
There are some special cases, where we need to do restacking of pop up
windows in timer.c . Also there are some existing bugs in a11y, we will
address them separately.
We are fixing this bug in incremental mode, all the remaining problem
will be fixed in CR6875930
*What we have fixied*
Xsun is consuming 100% cpu cycle with trusted path because of CR6769901
Also we found, with accessibility, cpu consumption goes to 100%
Popup window should not come through screensaver.
*Testing *
Barun and Arvind have tested new fixes very thoroughly
a) Pop-ups will not come through screensaver in case of dual head
display with and without xinerama . Same is the case when a11y is turned on.
b)Pop-ups will not come through screensaver with twinview display of
Xorg. Also there will be no performance degradation with my fixes
c) Pop-ups will not come through screensaver with trusted path
d) Pop-ups will not come through screensaver with all a11y cases
e) works fine with Xnewt,Xorg and Xsun
f) works fine with x86, x64, SPARC
g) The only pop-ups to get through are the ally pop-ups which are
allowed by design. GOK and MAG always on top of screensaver when we
lock the screen.
I am including svn diff of repository trunk/vermillion. For more detail
please see the attached source file.

* 5077974 P1 "Bug 147583: Screen Lock unlocks because of GOK dwell movement in
core pointer mode"
*
* ScreenLock did not unlock the screen, but WM's XRestackWindow() did.
* Once WM/metacity fixes the problem, the code can be removed.
The problem:
repositioning the Wids in the wrong positions when
1. the window type is changed from NORMAL to DOCK or vice versa
2. the Wid is managed
within the X window stack with or without screen-lock in a mixed Wids
there are two temp. get-around solutions:
1. non-managed GOK or MAG Wid
or
2. screensaver picks up the WM's restacking task and fixes the prevous
restacking problem.
the cons: there is a flashing screen when corepointer is touching
GOK or MAG and mouse is moved in a fast way
when GOK or MAG window type is DOCK only.
and it is not a good temp. get-around solution.
This is the only choice if WM did not want to fix the problem now
and AT group did not want to use non-managed Wids.
Now, GOK only supports 2nd USB/mouse/Dwell, corepointer is supposed
not to be used, and GOK cannot disable it
