The XFree86-xserv-4.3.0-34 'test' package has been updated in the Cygwin


Server source, direct link:
(134 KiB)

xc/programs/Xserver/hw/xwin (all files) diff against 4.3.0-33 source code:
(64 KiB)


1) winwndproc.c/winWindowProc/WM_DISPLAYCHANGE - Save value of
SM_C*VIRTUALSCREEN when fMultipleMonitors is true, instead of
SM_C*SCREEN.  (Harold L Hunt II)

2) winclipboardwrappers.c/winProcEstablishConnection - Change delay
in starting clipboard client from the 3rd call to the 4th call when
using Xdmcp.  Should fix the problem reported by Andrew Braverman; if
not, I'll have to make a much more robust system for starting the
clipboard client when using Xdmcp.  (Harold L Hunt II)

3) winclipboardwrappers.c/winProcSetSelectionOwner - Always advertise
CF_TEXT clipboard format, optionally advertise CF_UNICODETEXT format.
(Harold L Hunt II)

4) winclipboardwndproc.c/winClipboardWindowProc/WM_RENDERFORMAT - If
wParam is CF_UNICODETEXT, pass TRUE for Unicode support flag
(regardless of fUnicodeSupport value) when calling
winClipboardFlushXEvents.  (Harold L Hunt II)

5) winclipboardwndproc.c/winClipboardWindowProc/WM_DESTROYCLIPBOARD -
Add new handling for this message; we are supposed to process this
message for delayed rendering support.  (Harold L Hunt II)

6) General Clipboard - Restructure the clipboard system to run a
single thread, regardless of the number of screens created in the
current process; the reason for this is that X selections are
per-display, not per-screen, thus there is no reason to have one
thread per screen for managing the clipboard integration.  Changing
from per-screen to one thread greatly simplified the clipboard
handling code and reduced the likelihood of errors due to interaction
between multiple clipboard client threads.  (Harold L Hunt II)

7) winclipboardwrappers.c/winProcSetSelectionOwner - Track whether
the PRIMARY and CLIPBOARD selections are owned and if they are
transitioning from owned to not owned.  When one of PRIMARY or
CLIPBOARD is still owned the Win32 clipboard is not disowned; if both
PRIMARY and CLIPBOARD are not owned and a transition from one being
owned to being disowned is detected, then the Win32 clipboard is
disowned.  The user-level change is that you can select text in
certain X11 apps (which usually sets both the PRIMARY and CLIPBOARD
selections), click elsewhere to unselect the text (frees ownership of
one of the selections but not the other) and still paste the text in
Win32.  The previous behavior would not allow you to paste the text in
Win32 if the selection was no longer highlighted.  (Harold L Hunt

8) winclipboardwndproc.c/winClipboardWindowProc/WM_DRAWCLIPBOARD - We
cannot bail out when NULL == GetClipboardOwner() because some
applications deal with the clipboard in a manner that causes the
clipboard owner to be NULL when they are in fact taking ownership.
One example of this is the Win32 native compile of emacs.  Without
this fix, text could not be copied from the Win32 compile of emacs and
pasted within Cygwin/X.  (Harold L Hunt II)

9) InitOutput.c - Remember to delete the functions that were moved to
the new file called winprocarg.c.  (Harold L Hunt II)

To update your installation, click on the "Install Cygwin now" link on
the web page.  This downloads setup.exe to your
system.  Once you've downloaded setup.exe, run it and select "XFree86"
and then click on the appropriate field until the above announced
version number appears if it is not displayed already.

If your mirror doesn't yet have the latest version of this package after
24 hours, you can either continue to wait for that site to be updated or
you can try to find another mirror.
