38 | // NOTE (t.heintz): This is very evil to do, because the TBufferedTransport may swallow bytes, which | |
39 | // are then never written to the underlying transport. This happens precisely when a number of bytes | |
40 | // less than the max buffer size (512 by default) is written to the transport and then flush() is NOT | |
41 | // called. In that case the data stays in the writeBuffer of the transport, from where it can never be | |
42 | // accessed again (for example through read()). | |
43 | // | |
44 | // Since the caller of this method does not know about the wrapping transport, this creates bugs which | |
45 | // are very difficult to find. Hence the wrapping of a transport in a buffer should be left to the | |
46 | // calling code. An interface could used to mandate the presence of the putBack() method in the transport. | |
47 | // | |
48 | // I am leaving this code in nonetheless, because there may be applications depending on this behavior. | |
