Project: Thrift
Issue Type: Bug
Components: Haskell - Library

The read functions for handles promise to return _up_ to the requested number
of bytes. This means in case we read less bytes, we should try again to read
some more bytes. This issue caused invalid frame sizes which caused arbitrary
decoding failures.
I believe that the bug has been introduced in
[{{3c42007}}|https://github.com/apache/thrift/commit/3c420072ab5388c2c00d15ada72aec5b061c4d4d]
