hyper 0.1.0

HTTP/2 for Python

Latest Version: 0.3.1

HTTP is changing under our feet. HTTP/1.1, our old friend, is being supplemented by the brand new HTTP/2 standard. HTTP/2 provides many benefits: improved speed, lower bandwidth usage, better connection management, and more.

hyper provides these benefits to your Python code. How? Like this:

from hyper import HTTP20Connection

conn = HTTP20Connection('twitter.com:443')
conn.request('GET', '/')
resp = conn.getresponse()

print(resp.read())

Simple.

Caveat Emptor!

Please be warned: hyper is in a very early alpha. You will encounter bugs when using it. In addition, there are very many rough edges. With that said, please try it out in your applications: I need your feedback to fix the bugs and file down the rough edges.

Versions

hyper provides support for draft 14 of the HTTP/2 draft specification and draft 9 of the HPACK draft specification. As further drafts are released, hyper will be updated to support them.

Compatibility

hyper is intended to be a drop-in replacement for http.client, with a similar API. However, hyper intentionally does not name its classes the same way http.client does. This is because most servers do not support HTTP/2 at this time: I don’t want you accidentally using hyper when you wanted http.client.

Release History

0.1.0 (2014-08-16)

Regressions and Known Bugs

  • Support for Python 3.3 has been temporarily dropped due to features missing from the Python 3.3 ssl module. PyOpenSSL has been identified as a replacement, but until NPN support is merged it cannot be used. Python 3.3 support will be re-added when a suitable release of PyOpenSSL is shipped.
  • Technically this release also includes support for PyPy and Python 2.7. That support is also blocked behind a suitable PyOpenSSL release.

For more information on these regressions, please see Issue #37.

Major Changes

  • Support for HPACK draft 9.
  • Support for HTTP/2 draft 14.
  • Support for Sever Push, thanks to @alekstorm. (Issue #40)
  • Use a buffered socket to avoid unnecessary syscalls. (Issue #56)
  • If nghttp2 is present, use its HPACK encoder for improved speed and compression efficiency. (Issue #60)
  • Add HTTP20Response.gettrailer() and HTTP20Response.gettrailers(), supporting downloading and examining HTTP trailers. (Discussed in part in Issue #71.)

Bugfixes

  • HTTP20Response objects are context managers. (Issue #24)
  • Pluggable window managers are now correctly informed about the document size. (Issue #26)
  • Header blocks can no longer be corrupted if read in a different order to the one in which they were sent. (Issue #39)
  • Default window manager is now smarter about sending WINDOWUPDATE frames. (Issue #41 and Issue #52)
  • Fixed inverted window sizes. (Issue #27)
  • Correct reply to PING frames. (Issue #48)
  • Made the wheel universal, befitting a pure-Python package. (Issue #46)
  • HPACK encoder correctly encodes header sets with duplicate headers. (Issue #50)

0.0.4 (2014-03-08)

  • Add logic for pluggable objects to manage the flow-control window for both connections and streams.
  • Raise new HPACKDecodingError when we’re unable to validly map a Huffman-encoded string.
  • Correctly respect the HPACK EOS character.

0.0.3 (2014-02-26)

  • Use bundled SSL certificates in addition to the OS ones, which have limited platform availability. (Issue #9)
  • Connection objects reset to their basic state when they’re closed, enabling them to be reused. Note that they may not be reused if exceptions are thrown when they’re in use: you must open a new connection in that situation.
  • Connection objects are now context managers. (Issue #13)
  • The HTTP20Adapter correctly reuses connections.
  • Stop sending WINDOWUPDATE frames with a zero-size window increment.
  • Provide basic functionality for gracelessly closing streams.
  • Exhausted streams are now disposed of. (Issue #14)

0.0.2 (2014-02-20)

  • Implemented logging. (Issue #12)
  • Stopped HTTP/2.0 special headers appearing in the response headers. (Issue #16)
  • HTTP20Connection objects are now context managers. (Issue #13)
  • Response bodies are automatically decompressed. (Issue #20)
  • Provide a requests transport adapter. (Issue #19)
  • Fix the build status indicator. (Issue #22)

0.0.1 (2014-02-11)

  • Initial Release
  • Support for HTTP/2.0 draft 09.
  • Support for HPACK draft 05.
  • Support for HTTP/2.0 flow control.
  • Verifies TLS certificates.
  • Support for streaming uploads.
  • Support for streaming downloads.
