Patch Name: PHCO_12862

Patch Description: s700_800 10.20 sed(1) cumulative patch

Creation Date: 97/10/12

Post Date:  97/10/14

Warning: 98/02/23 - This Non-Critical Warning has been issued by HP.
	- PHCO_12862 introduces a problem in sed(1) when a locale
	  other 'C' is used.  When the LANG variable is set to one
	  of these locales, the end-of-line anchoring character '$'
	  is not recognized.
	- The problem is caused by a defect in the underlying
	  regular expression comparision routine provided in
	  libc.a.  When the problem is corrected in libc, a
	  new patch will be created and released.
	- Patch PHCO_10868 does not exhibit this problem and will
	  be re-released until a replacement patch is available.
	- It is recommended that PHCO_12862 be removed from systems
	  on which sed(1) is used to match the end-of-line anchoring
	  character '$' and locales other than 'C' are used.  If
	  sed(1) is not used to match the end-of-line anchoring
	  character or if the 'C' locale is used then the patch does
	  not need to be removed.
	- Patch PHCO_12862 was included in the following bundles on
	  the February 1998 Extension Software release:
		XSW700GR1020 revision B.10.20.37
		XSW800GR1020 revision B.10.20.37

Defect Description:
	PHCO_12862:
	1. sed '/^$/d' inputfile - does not function correctly in
	   Japanese locale. This is due to a defect in PHCO_10868.
	   The libc patch PHCO_10027 which was used in building
	   the sed patch was defective.

	PHCO_10868:
	2. sed -n -e '/^.*1$/p' -e '/[23]$/p' doesn't handle
	   regexp correctly.
	   'sed' for 10.20 (rev 78.9.1.1) has a defect searching
	   for string.
	   10.20's sed broken using pattern "/\A$/" in script.
	   sed does not handle next/join command.

Installation Instructions:
	Please review all instructions and the Hewlett-Packard
	SupportLine User Guide or your Hewlett-Packard support terms
	and conditions for precautions, scope of license,
	restrictions, and, limitation of liability and warranties,
	before installing this patch.
	------------------------------------------------------------
	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_12862

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

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHCO_12862.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_12862.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_12862.  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_12862.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_12862.depot of=/dev/rmt/0m bs=2k
