	s800: 10.20

Path Name: /hp-ux_patches/s700_800/10.X/PHCO_14654

Symptoms:
	PHCO_14654:
	The delwin(3X) coredumps in some cases.

	PHCO_11342:
	The X/Open curses API getch() waits indefinitely for
	input to complete a keypad sequence.

	PHCO_11036:
	Various XCurses APIs were fixed during 10.30 and
	the same had to be backported to 10.20.

	PHCO_9295:
	1.  In 10.20, high-lighted fields cannot be reverted
	    to normal in an application which links with -lcurses.
	2.  Application uses select() systems call  core dumps.

Defect Description:
	PHCO_14654:
	The call to delwin() coredumps in some remote cases.
	This is basically because of a buffer overflow in the
	library.

	PHCO_11342:
	When keypad is enabled, the X/Open curses API getch()
	should wait for some time after <ESC> key is pressed for
	the next key to be pressed and return that sequence. If
	no key is pressed for some time the API should return
	<ESC> alone. Currently getch() waits indefinitely for
	the next key to be pressed when <ESC> is pressed.

	PHCO_11036:
	The 10.30 fixes to various XCurses APIs have been
	backported to 10.20.

	PHCO_9295:
	1.  10.20 X/Open curses: high-lighted fields cannot
	    be reverted to normal
	2.  10.10 enhanced X/Open curses core dumps due
	    to using wrong select call.

Installation Instructions:

	------------------------------------------------------------
	1. Back up your system before installing a patch.

	2. Login as root.

	3. Copy the patch to the /tmp directory.

	4. Move to the /tmp directory and unshar the patch:

		cd /tmp
		sh PHCO_14654

	5a. For a standalone system, run swinstall to install the
	    patch:

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHCO_14654.depot

	5b. For a homogeneous NFS Diskless cluster run swcluster on the
	    server to install the patch on the server and the clients:

		swcluster -i -b

	    This will invoke swcluster in the interactive mode and
	    force all clients to be shut down.

	    WARNING: All cluster clients must be shut down prior to the
		     patch installation.  Installing the patch while the
		     clients are booted is unsupported and can lead to
		     serious problems.

	    The swcluster command will invoke an swinstall session in which
	    you must specify:

		alternate root path  -  default is /export/shared_root/OS_700
		source depot path    -  /tmp/PHCO_14654.depot

	    To complete the installation, select the patch by choosing
	    "Actions -> Match What Target Has" and then "Actions -> Install"
	    from the Menubar.

	5c. For a heterogeneous NFS Diskless cluster:

		- run swinstall on the server as in step 5a to install
		  the patch on the cluster server.

		- run swcluster on the server as in step 5b to install
		  the patch on the cluster clients.

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHCO_14654.  If you do not wish to retain a
	copy of the original software, you can create an empty file
	named /var/adm/sw/patch/PATCH_NOSAVE.

	Warning: If this file exists when a patch is installed, the
	         patch cannot be deinstalled.  Please be careful
		 when using this feature.

	It is recommended that you move the PHCO_14654.text file to
	/var/adm/sw/patch for future reference.

	To put this patch on a magnetic tape and install from the
	tape drive, use the command:

		dd if=/tmp/PHCO_14654.depot of=/dev/rmt/0m bs=2k
