[hylafax-users] Am I being a pest yet? :) (awk conversion script infinite loop...)

[Karl Denninger <karl@xxxxxxxxxxxxx>]

So I got most of the new server version stuff figured out, and decided 
I'd try to have the system convert incoming faxes to PDFs and email 
them.  (I moved the "high port assignment" range on the box and opened 
that range; this should be reasonably "safe" and allows the passive mode 
to work for remote clients.  Not ideal but I can live with it.)

Encoding to PDFs is simple and supported, right?

Uh, not quite.  The b64-encode.awk function goes into an infinite loop 
on my system (FreeBSD 6.2-STABLE) when presented an imput file.  It does 
first encode the correct data file but then starts returning an infinite 
stream of nonsense.

Here's what I'm getting when invoked manually on a short file:

awk -f b64-encode.awk archive | more  produces.....

With the last part repeating until killed.

Needless to say this makes the translation not work!

I assume this has something to do with the read loop not detecting EOF 
correctly, although the code LOOKS ok......

Something that might need to be looked at..... I've set it back to send 
TIF files until this can be investigated.
