Timothy Bish commented on AMQCPP-235:
-------------------------------------
Thanks for the input. Combining the code would have been ideal but I'm
planning on splitting the decaf library out at some point into its own lib for
use on some other projects so the AMQCPP client can't depend on that code so I
kept them separate.
> UTF8 length marshalling bug in openwire readString and writeString.
> -------------------------------------------------------------------

> Key: AMQCPP-235

> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Components: Openwire

> Reporter: Martin Schlapfer
> Assignee: Timothy Bish

> In investigating a bug for the check "if( str->size() > 65536 )" which should
> be "if( str->size() > 65535 )" in writeString() , I found a couple of other
> problems:
> (1) The OpenwireStringSupport::readString method should read the utf8 length
> as an unsigned short rather than short. The problem is that utf8 encoded
> strings (using writeString) longer than 32768 will become truncated when read
> back using readString().
> (2) The writeString() method should also check the value of utflen after
> determining the UTF8 length of the encoded string, since with the support of
> characters greater than value 127, encodings of 2 UTF8 bytes per byte can
> exist.
