AltME: R3 Protocols


@Andreas, did your pop3 scheme check every single line of data coming down for codes?
no, you only have to check the immediate response line or the line after that, depending on the command.
for message data (RETR) you know beforehand how many data you ought to receive.
then it's just a question if you want to rely on that, or be very defensive, assume the pop3 server is broken regarding size calculation and rather continuously check for `crlf #"." crlf` instead.
I'm being defensive and also checking for octet stuffing
unfortunately, quite a few pop3 servers indeed are broken in this regard, however, they typically err in giving too small sizes. so you can just read as much as you are told to and then switch to "dot-scanning".
Probably why my version times out on a 5Mb file after a minute

Graham, I made some corrections to the tls scheme so the problems(eg. write from connect and the port/data compatibility) you reported should be fixed. Please get it from here and give it a try.
Will try it today. Thanks.

Ah, sorry. It seems the code is 'too new'..we need to make new release of R3 Saphirion fork so you are able to run it.
First 5 minutes of testing shows that in  the new release, the tls port is now more like the tcp port

Could use R2 probably, but - can R3 read ftp? I will soon need small script for my LED screen client, who requests placing commercials himself. So my idea is to allow them to place it to FTP server, then my script takes it, downloads it, and rewrites the file locally ...
There's no ftp protocol built into R3, and I haven't heard of anyone making one. Maybe Kaj's curl wrapper can do ftp.
When I look at dev-net.c source it seems like UDP is only one switch. Would it be the UDP actor the same as for TCP or may it be less complicated?
The cURL binding can do FTP, of course
We've been uploading our websites with it for several years
I wrote a ftp scheme three years ago ... and was able to download ISO images with it.
Pekr, you forget so quickly!
As do I :)
to sys/make-scheme
and it should work. I did test it a week ago to confirm this.
