Path Name: /hp-ux_patches/s700_800/11.X/PHCO_27057

Symptoms:
	PHCO_27057:
	( SR:8606228872 CR:JAGad97925 )
	vi(1) cannot handle files, with lines having more
	than 2048 chars.

	PHCO_25987:
	( SR:8606144118 CR:JAGad13451 )
	vi(1) dumping core when LANG is set to arabic and when
	some text is appended to existing line.

	( SR:8606187176 CR:JAGad56384 )
	If the user resizes the window , while  a large data
	file is still  being opened by vi(1),data corruption
	is noticed.

	( SR:8606214324 CR:JAGad83515 )
	Some characters for the new Chinese locale conforming to
	the GB18030 codeset cannot be displayed using the vi
	editor.

	( SR:8606229299 CR:JAGad98352 )
	If the user resizes the window, while '/' search is
	being done in vi(1) session,data corruption is noticed.

Defect Description:
	PHCO_27057:
	( SR:8606228872 CR:JAGad97925 )
	vi(1) was unable to handle files containing lines
	of length greater than 2048 characters.This was
	because, the buffers used in vi(1) were limited
	to 2048 characters.

	The problem can reproduced in the following way:

	$ echo "HELLO" > m
	$ perl -e 'print "l" x 2047' >> m
	$ vi m
	HELLO
	~
	~
	"m" Line too long

	Resolution:
	The size of buffers has been changed from 2048
	to 4096 characters.

	PHCO_25987:
	( SR:8606144118 CR:JAGad13451 )
	vi(1) dumps core when LANG is set to arabic and when
	user attempts to append text to the existing line.
	This was due to negative values were being sent to
	memcpy library rountine in some cases.

	Resolution:
	The code has been changed now to validate the argument
	values sent to memcpy library function.

	( SR:8606187176 CR:JAGad56384 )
	If window is resized while vi(1) is loading a huge
	file,data in the file gets corrupted when the
	file is saved.This was because of improper handling of
	SIGWINCH signal in vi(1) while loading a file.

	 The problem can reproduced in the following way:

	- Create the file "data1" which is more than 2MB size.
	- Copy the "data1"  file into "data2"
	- vi the "data1" file in an hpterm.
	- While loading the file, resize the window.
	- Save and quit from vi.
	- Now take the diff of two files(data1,data2).There
	  will be difference between the above two files.

	Resolution:

	The code has been changed to handle SIGWINCH
	properly while a data file is being loaded.

	( SR:8606214324 CR:JAGad83515 )
	Using  vi editor some characters for the new Chinese
	locale conforming to the GB18030 codeset cannot be
	displayed . It was observed that the values used by
	macros are same as wide character values.

	  The problem can be reproduced as follows:

	- Set LANG to zh_CN.gb18030

	$ export LANG=zh_CN.gb18030

	- Create a file temp1 as follows.

	$ echo "\0251\0126\0251\0127" > temp1
	$ cat temp1
	`V`W
	$

	- Run "vi temp1" on a dtterm, you will not be able to see
	  any characters on the screen.

	Resolution:
	Now the macros have been assigned new values which fall
	outside the range of valid wide character values for
	all the existing locales.

	( SR:8606229299 CR:JAGad98352 )
	If window is resized while a '/' search command
	is performed on data file , data in the file
	gets corrupted when the file is saved.
	This was because of improper handling of SIGWINCH
	signal in vi(1) during pattern searching.

	 The problem can be reproduced as follows:

	- Create a file temp1 with > 1000000 lines.No two
	  lines should be the same.  Copy temp1 to temp2.
	- Search for a particular pattern which is not
	  present in the file or one which is present but
	  towards the end of the file so that the search
	  operation takes time.
	- Resize the terminal while the search is taking place.
	  Wait until the search operation is over.
	- Save and quit from vi.
	- Now take the diff of two files(temp1,temp2).There
	  will be difference between the above two files.
	  temp1 & temp2.

	Resolution:
	The code has been modified to handle SIGWINCH properly
	while a '/' search command is performed in vi(1)
	session.
