Subject Re: [PATCH] fields in XOVER containing newline or tab disturb client
Date Mon, 02 Sep 2002 18:52:40 GMT

Using -Dapache.nntp.debug=true was my first aproach. But what I got was just
an output like
S: -1
:( this is because in the implementation of  PrintWriter in
NNTPHandler.handleConnection() only has a debug hook
in println(), but does not overwrite print(). So I decided to assemble the
line using StringBuffer rather than
overwrite print() and buffer the data just for debugging purposes.

So using this solution will give full usable output
whenever -Dapache.nntp.debug=true has to be used next.
I also checked that there are no further occurences of PrintWriter.print()
calls which could produce
missing debug data.
