Iliya Gurov created THRIFT-4201:
-----------------------------------
Summary: False positive timeout or blocking recv in the
THttpTransport client
Key: THRIFT-4201
URL: https://issues.apache.org/jira/browse/THRIFT-4201
Project: Thrift
Issue Type: Bug
Components: C++ - Library
Affects Versions: 0.10.0
Reporter: Iliya Gurov
Before we get more data by doing refill in the THttpTransport::readMoreData(),
we need to check whether we have already the entire content in the buffer
(fetched in the last ::recv while processing the previous chunk). Doing refill
without this check may lead to calling ::recv even though all chunks (the
entire content) are already in the buffer. The effect of this is that the call
fails either with a false positive timeout or blocks in recv if no timeout is
configured
