1. missing 13; upload script
I'm struggling with an upload CGI script. (Again.)
The problem is rather strange... I collect the input with get_bytes(0,i) but the
returned sequence sometimes misses some 13 bytes from the file part. What is
going on? Any idea?
Thanks in advance!

Be careful to upload binary files using the BINARY option (not ASCII)
in your FTP program. Otherwise you might have 13 10 (i.e. CR LF)
character combinations converted to just a 10.

Actually I'm experimenting with HTTP. The upload is started with a
multipart/form-data HTML FORM. I tested it with Opera and Abyss webserver. I
parse the input but does not replace {13,10} with {10} but it simply skips 13
sometimes. (But not all 13 bytes!)
Eg. some sequence parts:
s1[i1..i2]={10,12,20,13,12,11,11}
s2[i1..i2]={10,12,20,12,11,11,12}
The way I found this problem was comparing the original and the uploaded JPG
byte by byte. I am clueless. Should be something really obvious...

From get_bytes notes:
include get.e
integer fn
fn = open("temp", "rb") -- an existing file
sequence whole_file
whole_file = {}
sequence chunk
while 1 do
chunk = get_bytes(fn, 100) -- read 100 bytes at a time
whole_file &= chunk -- chunk might be empty, that's ok
if length(chunk) < 100 then
exit
end if
end while
close(fn)
? length(whole_file) -- should match DIR size of "temp"
Does this happen ? size match I mean.

As far as I see your code has not much to do with my problem.
In my case a file uploaded by an HTML FORM and saved by an EU
CGI script running under windows differs from the original
binary file. Your code can check a file read by get_byte and
saved by a local EU script to the original binary file.
My problem may come from the unique STDIN handleing in Euphoria.
But I am not sure at all. {:-.
