[Twisted-Python] Twisted 16.3.0 Prerelease 2 Announcement

[Cory Benfield]

Good catch Paweł. I have opened this issue as Twisted issue #8558: https://twistedmatrix.com/trac/ticket/8558 <https://twistedmatrix.com/trac/ticket/8558>. I believe I know what the fix is and it’s fairly simple, so I’ll try to address this quickly and see if we can ship the fix in either the next pre-release or in the actual 16.3 release.

I created simple gist to recreate this issue see here: https://gist.github.com/pawelmhm/3aa7e4f3a0e322364dcb75e3f0a32da4 <https://gist.github.com/pawelmhm/3aa7e4f3a0e322364dcb75e3f0a32da4> Resource is launched with Python 3.4, to test it on the client I used curl with http2 support. Data file <https://drive.google.com/file/d/0B6myg3n6dqcVcXpPdkJCNUJLOTA/view?pref=2&pli=1> is not huge (570kb) but the error is raised when I send it as a whole, when I only send some smaller chunk (e.g. first 100 items from file) it seems to work ok. It seems that Python-hyper is all right with this file, perhaps curl --http2 does something weird.
