Telnet char-at-a-time problem still exists?
Folks,
I really think this is a showstopper for 2.0 - unless folks can test
the server feeding characters at a time, we are broken. I see no problem
with setting a timeout for the complete request to be assembled (to avoid
DNS attacks) but the current situation seems pretty intollerable.
I was just closing a bugreport that required me to check the contenttype
of a file, so I tried telnet to HEAD that file, and it pretends I don't
exist (no response.) It took me 1/2 hour to remember this bug.
Did someone start working out the fix?
Bill

This was a killer on BeOS so once I've slept I'll see if we still have a
problem there, but it was all working a short while ago...

I originally tested with telnet from Win98, and this weekend, I forced my
Linux telnet into char-at-a-time mode, and ran a few simple tests, and it
seemed to work. I was trying to replicate the assertion failure, but
couldn't. I didn't pay much attention to this bug, but the fact that the
char-at-a-time worked for my testing is a good thing.

I tested it a bunch too, back when we were working on input filtering,
ap_getline(), and the mime header folding stuff. I tried it again just
now, and it works fine for me. I used telnet from WinNT 4.

This did work at one time. I tested this VERY extensively using my one
Windows 98 machine. If it no longer works, then it is because somebody
modified the input filters. I know that it did work at one time.
