Timothy Bish updated AMQCPP-371:
--------------------------------
Description:
If the URI option connection.useCompression=true, an ActiveMQBytesMessage's
size will always become doubled. I changed the ActiveMQByteMessage.cpp as
follow, the problem seems been solved.
{code}
class ByteCounterOutputStream : public FilterOutputStream {
private:
int* length;
private:
ByteCounterOutputStream( const ByteCounterOutputStream& );
ByteCounterOutputStream operator= ( const ByteCounterOutputStream& );
public:
ByteCounterOutputStream( int* length, OutputStream* stream, bool own = false )
: FilterOutputStream( stream, own ), length( length ) {
}
virtual ~ByteCounterOutputStream() {}
protected:
virtual void doWriteByte( unsigned char value ) {
(*length)++;
FilterOutputStream::doWriteByte( value );
}
virtual void doWriteArray( const unsigned char* buffer, int size ) {
//(*length) += size; removed because of length has been double sized
FilterOutputStream::doWriteArray( buffer, size );
}
virtual void doWriteArrayBounded( const unsigned char* buffer, int size, int
offset, int length ) {
//(*this->length) += length; removed because of length has been double sized
FilterOutputStream::doWriteArrayBounded( buffer, size, offset, length );
}
};
{code}
