A few observations:
1. WOW.... nice touch! Smoothed out ALL of my headaches
here with the gateway. Particularly SECURITY!!!
2. Thanks for fixing the ^b problem! (I hate the "smiling
bastard" character.... 8-} ) Adding cls was also nice.
3. Memory Leaks!...... still running into severe sudden
memory "hemorrhage" on my 386sx 16 (Phoenix Bios)... on a
quiet ethernet, a "private" SLIP link, and an AX25 port
that is used by the encap gateway users. OS is mess-doo 5
and sometimes Windows 3.0... (symptoms occur independent of
-some appears to occur related to the inability of
the memory code to "recover" surrendered malloc
after a number of sessions are closed.
-other observations after a weekend of use... if
(for whatever reason! ;-} ) a remote session
through the gateway closes (read: is probably
dropped by remote user) without a final ack/RST a
number of close pending and close wait sessions
stack up. This is almost universally fatal! The
throughput and response time of the system
approaches 6802 or worse, then locks up. Net log
shows no abnormalities through the last log update,
however, a number of .tmp files are open and left
-recovery from either state by kicking or resetting
the individual sessions does not improve the memory
situation for up to 10 hours afterward. As has been
noted by many users... the direct symptoms are that
heap continues to grow, and freeheap varies from 8%
to 20%... while morecores continue to drop to the
point that a shell invocation is no longer
possible. The time it takes to reach "critical" is
on the order of 16 to 48 hours. (BTW.. all code,
Phil's December release, Gerards 1.8b and c, and
yours all seems to do this in my environment.
Since I dont have time to "go into the larval stage" with
the code and have barely had time (approaching Ph.D. thesis
defense in Microbial Genetics....|8-[} ) to play with my
compiler, I use the code compiled and distributed by the
author of each particular release. As a "beta" tester, I think
this is a better approach (eliminates compiler and "luser"
errors!!!) anyway because the author has an idea how to
look for a problem in his own development context.
One other comment.. Could you and Gerard "slow down and
catch up with each other"? You are leapfrogging each other
with your stuff because you both are so quick with this
stuff. You indicated you used GRI 1.8a as your basis code
and Gerard has both debbugged it AND added some of your
features to his release 1.8c! Nice place to begin the next
round would be to diff yours and his and then "reunify" at
1.8d or what ever.....
Both of you, keep up the great work, you have done a nice
job with Phil's latest code!!
