Subject [jira] [Created] (CRYPTO-135) CryptoOutputStream is always blocking
Date Wed, 15 Feb 2017 19:48:41 GMT
Marcelo Vanzin created CRYPTO-135:

             Summary: CryptoOutputStream is always blocking
                 Key: CRYPTO-135
             Project: Commons Crypto
          Issue Type: Bug
          Components: Stream
    Affects Versions: 1.1.0
            Reporter: Marcelo Vanzin

CRYPTO-125 described a bug where not all data written to the CryptoOutputStream would make
it to the underlying channel if that channel was non-blocking.

The fix added in that bug makes CryptoOutputStream blocking by doing a busy loop. This makes
it a poor match (not to say unusable) for applications that use non-blocking channels, since
it will turn non-blocking streams into blocking streams that waste a lot of CPU.

Instead, CryptoOutputStream should correctly implement non-blocking semantics in its implementation
of WritableByteChannel.
