I could do that, but then I'm not sure how to set up a test for it. Could you elaborate on how you want the waiting-forever issue to be fixed? I can try writing a patch for that first. |

This tests that a client always sends the connection preface before any other frame (see PR kazu-yamamoto#33).

I rebased this branch so that it only contains the preface race fix. I wrote a patch employing async to propagate exceptions and thread termination to the main client thread, based on this one: wireapp@617c685, and the preface test is now based on both of these patches: wireapp@fb4afa7. Should I submit these as separate PRs or include them here? |

Thank you for brushing up this PR. What I did so far is reordering these commits:
If you kindly make this PR in this order, I'd love to merge. |
This tests that a client always sends the connection preface before any other frame (see PR kazu-yamamoto#33).
This fixes a race condition in the client between the `frameSender` thread and the main thread, in the case where a SETTINGS frame is sent in response to a server SETTINGS frame before the connection preface has had a chance to be sent.
Also throw an exception if one of the worker threads terminates before the client has received a response.

Merged. Thank you for your contribution! |

Thanks for merging!
We are fine depending on a git version, so up to you. Also, I will probably have more PRs coming in the next few days. |

So, I wait for the PRs. |

This fixes a race condition in the client between the
frameSenderthread and the main thread, in the case where a SETTINGS frame is sent in response to a server SETTINGS frame before the connection preface has had a chance to be sent.This PR also includes a commit to prevent client threads from waiting forever on stream input when the client
frameSenderthread dies. This is useful in its own right, I think, but in particular it is needed to make the test for the above fix work.
