[hacknews] running new Unix

henry@utzoo.UUCP (Henry Spencer) (09/19/84)

Tested and booted a new unix, now operational.  The last of the DZs are
now out of the system (although still physically resident in the cpu box),
and all terminals are running on DHs.  The paging mode of the tty driver
has been improved to handle wraparound on long lines, to be temporarily
turned off by a settable character, and to prompt with a settable character.
(Suitable paging defaults will be integrated into setpage(1) in the next
day or so; please don't hard-code your own meanwhile.)  The inode-search
code in the kernel has been modified to start where it left off, instead of
at the beginning, which should eliminate the "pregnant pause" phenomenon
in the editors and the accompanying transient heavy load.  The kernel
allocation code for blocks and inodes has been revised to maintain free
counts, which however are not initialized or looked at by the relevant
software yet (soon...).  The tty driver has been modified so that backslash
erase always puts a backspace into the document, regardless of the precise
choice of erase character, if erblank mode is on (which it is by default
for everybody).

Nobody's perfect, there are two things wrong.  The line-wrap code isn't
right, it stops prematurely (it's harmless but definitely wrong).  I know
where the problem is, we'll fix this (probably) tomorrow.  And, a bit more
seriously, the 5121 line is out of order until tomorrow and will not be
working as a dialin for the next few days.  The DH driver doesn't have
some of the DZ driver's kludgey dialout code yet, and until this is done
5121 will be dedicated to dialout and the alternate dialout (2581) won't
dial out at all.  Furthermore, until we get a jumper (software or hardware)
on 5121, it won't dial out either, due to an oversight.

Stay tuned.
