[jira] [Commented] (THRIFT-3481) introduce TSimpleMemoryTransport which wraps a customer owned memory chunk to conduct both read and write operations

Xiaoshuang LU commented on THRIFT-3481:
---------------------------------------

{code}
    // sufficiently large
    char buffer[4096];

    boost::shared_ptr<TMemoryBuffer> transport{ new TMemoryBuffer(buffer, 1024, 
TMemoryBuffer::OBSERVE) };
    boost::shared_ptr<TBinaryProtocol> protocol{ new TBinaryProtocol(transport) 
};

    object.write(protocol.get());
{code}

We will get

{code}
terminate called after throwing an instance of 
'apache::thrift::transport::TTransportException'
  what():  Insufficient space in external MemoryBuffer
Aborted (core dumped)
{code}

> It would be great if there is a transport class which 1. does not need to 
> care about the memory management, 2. is capable of both read and write 
> operations.
> TMemoryBuffer is very close to the requirements, but no data can be written 
> to observed TMemoryBuffer as stated in the comments.
