I should also mention that I'm using Saxon 6.5 as my XSLT engine.

Subject: [Possible Bug] TextSerializer loses characters with ASCII
encodin g?


Hi folks,

I'm seeing some really odd behavior with serializers, and wanted to see if
anyone had seen this before (or better yet) knows what's causing this.  =)

PROBLEM:
If I set an XML, HTML, or Text serializer's encoding to ASCII, I end up
losing the tail end of my output (roughly 1-1000 characters).  I think it
has to do with the buffered output stream not being properly closed/flushed,
but I'm not sure.

ENVIRONMENT:
Cocoon 2.0.2 running on JBoss 2.4.5 with Tomcat 4.0.3.  Win2k.

WORKAROUNDS:
I can make this problem go away by doing either of the following:
  1. Change the encoding to UTF-8 or ISO-8859-1.
  2. Change the buffer-size to 1 (tried with values from 1-2048;
     was still seeing the problem with values as low as 10).

REPRODUCING THE BUG:
>From what I'm seeing, you can reproduce this bug by having a reasonably
large buffer (larger than 10 bytes) and switching any TextSerializer-based
serializer's encoding to ASCII.  Here's a sample from my sitemap:

	<map:serializer name="css" mime-type="text/css"
logger="sitemap.serializer.css"
                    src="org.apache.cocoon.serialization.TextSerializer"
                    pool-max="64" pool-min="16" pool-grow="4">
		<buffer-size>2048</buffer-size>
		<encoding>ASCII</encoding>
	</map:serializer>

Any thoughts, suggestions, ideas, etc. would be greatly appreciated.
Thanks!

Harry

PS  The main reason this comes up is for a dynamic css pipeline, which I'd
like to be character set agnostic (hence, the ASCII encoding).  I only
tested it with the HTML and XML serializer to make sure it wasn't something
specific to my css pipeline.
