Dominic Coyne created THRIFT-4620:
-------------------------------------
Summary: TZlibTransport.cpp doesn't ensure that there is enough
space for the zlib flush marker in the buffer.
Key: THRIFT-4620
URL: https://issues.apache.org/jira/browse/THRIFT-4620
Project: Thrift
Issue Type: Bug
Components: C++ - Library
Affects Versions: 0.9
Reporter: Dominic Coyne
I asked [this
question|https://stackoverflow.com/questions/51784225/how-does-thrift-handle-zlib-flush-markers-being-split-over-multiple-messages]
on stack overflow related to a crash that I have been getting with Thrift.
The problem occurs when using TZlibTransport.cpp. After writing to the buffer a
few times, we do a flush. If there isn't enough space in cwbuf_ , the Thrift
flush marker is split across two messages, which causes an error in the client,
as a deflate stream can't start with a partial flush marker, ff.
Thrift should assure that there will be enough space in the buffer for the
complete flush marker, before a deflate.
