vt pollutes environment #186

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
vt will pollute environment with some variables, preventing other programs that 
depend on them from working (vim from contrib)

fixed by adding RFENVG to rfork. patch: http://sprunge.us/TSCJ

chi% ls /env > env.1
chi% ./vt -ab
draw: eof on event pipe: 
chi% ls /env > env.2
chi% diff env.1 env.2
2a3
> /env/COLS
4a6
> /env/LINES
5a8
> /env/TERM
6a10,11
> /env/XPIXELS

this is intentional and part of the tty emulation for ape programs.

correction, mischief is right. the vars only need to be visible by
the process (shell) running under vt. fixed in r2a817c6ecfd1
