Clients closing connections


The client can simply close the connection without sending QUIT. 
This saves time and memory for both the client and the server.

There are a few broken TCP implementations, such as MacTCP 2.0.6, 
that fail to acknowledge TCP FINs after a local close. If the client 
is running on such a host, it shouldn't close the connection until 
after it sends QUIT and sees the server close the connection; otherwise 
the server will waste time repeatedly transmitting the FIN until 
it times out.

ok, need to close

must be why when I login to chat .. .I start getting more messages 
from my ftp handler!

here's the updated version (i also bumped the version number): http://bolka.at/share/prot-ftp.r, 
here's the full diff to 0.0.5: http://gist.github.com/274796

there's also a lovely gem contained in that code, btw

your dataport is never WAITed on

as there's a WAIT on the ftp scheme port already, simply OPENing 
the dataport suffices to have it scheduled and receiving events

ahh... I wondered how that worked

Impressive .. it works fast!

yes

and that with all the debug output

das RETR take full paths?

for where?

I don't know if the ftp server will take a full path but the client 
can

could i have a minimal FTP thingie with just USER/PASS/PASV/RETR?

TYPE

TYPE I would be needed as well

yes

I don't know if the server will accept a path ...

i'll try :)

try it ..

should work, iirc

yeah, works fine

great ...

and you can just queue commands with the WRITE

dunno if two consecutive RETR wil work though

you'll at least need another PASV before the 2nd RETR

Does the WRITE set off the handler again?

guess it needs another read ..

from within the awake handler: yes

from the outside: no

ok, that's the important thing

but it'll be buffered anyway

so if the event machinery already is in full swing :)

ah, graham .... :)

hold me back

HOLD

good

down boy down

wow, there is a tail? actor

where are the available actors documented?

someone had a link the other day which mentioned that the series 
protocol should be available completely

can't remember the link, though :)

makes sense

Do you actually use ftp much ?

nope

never :)

me hardly much either!

last time i used it was years ago

so why do we do ftp, then :) ?
