Software Updates

Release History

2.2.1 (2014-01-23)

Bugfixes

  • Fixes incorrect parsing of proxy credentials that contain a literal or encoded ‘#’ character.
  • Assorted urllib3 fixes.

2.2.0 (2014-01-09)

API Changes

  • New exception: ContentDecodingError. Raised instead of urllib3 DecodeError exceptions.

Bugfixes

  • Avoid many many exceptions from the buggy implementation of proxy_bypass on OS X in Python 2.6.
  • Avoid crashing when attempting to get authentication credentials from ~/.netrc when running as a user without a home directory.
  • Use the correct pool size for pools of connections to proxies.
  • Fix iteration of CookieJar objects.
  • Ensure that cookies are persisted over redirect.
  • Switch back to using chardet, since it has merged with charade.

2.1.0 (2013-12-05)

  • Updated CA Bundle, of course.
  • Cookies set on individual Requests through a Session (e.g. via Session.get()) are no longer persisted to the Session.
  • Clean up connections when we hit problems during chunked upload, rather than leaking them.
  • Return connections to the pool when a chunked upload is successful, rather than leaking it.
  • Match the HTTPbis recommendation for HTTP 301 redirects.
  • Prevent hanging when using streaming uploads and Digest Auth when a 401 is received.
  • Values of headers set by Requests are now always the native string type.
  • Fix previously broken SNI support.
  • Fix accessing HTTP proxies using proxy authentication.
  • Unencode HTTP Basic usernames and passwords extracted from URLs.
  • Support for IP address ranges for no_proxy environment variable
  • Parse headers correctly when users override the default Host: header.
  • Avoid munging the URL in case of case-sensitive servers.
  • Looser URL handling for non-HTTP/HTTPS urls.
  • Accept unicode methods in Python 2.6 and 2.7.
  • More resilient cookie handling.
  • Make Response objects pickleable.
  • Actually added MD5-sess to Digest Auth instead of pretending to like last time.
  • Updated internal urllib3.
  • Fixed @Lukasa’s lack of taste.

2.0.1 (2013-10-24)

  • Updated included CA Bundle with new mistrusts and automated process for the future
  • Added MD5-sess to Digest Auth
  • Accept per-file headers in multipart file POST messages.
  • Fixed: Don’t send the full URL on CONNECT messages.
  • Fixed: Correctly lowercase a redirect scheme.
  • Fixed: Cookies not persisted when set via functional API.
  • Fixed: Translate urllib3 ProxyError into a requests ProxyError derived from ConnectionError.
  • Updated internal urllib3 and chardet.

2.0.0 (2013-09-24)

API Changes:

  • Keys in the Headers dictionary are now native strings on all Python versions, i.e. bytestrings on Python 2, unicode on Python 3.
  • Proxy URLs now must have an explicit scheme. A MissingSchema exception will be raised if they don’t.
  • Timeouts now apply to read time if Stream=False.
  • RequestException is now a subclass of IOError, not RuntimeError.
  • Added new method to PreparedRequest objects: PreparedRequest.copy().
  • Added new method to Session objects: Session.update_request(). This method updates a Request object with the data (e.g. cookies) stored on the Session.
  • Added new method to Session objects: Session.prepare_request(). This method updates and prepares a Request object, and returns the corresponding PreparedRequest object.
  • Added new method to HTTPAdapter objects: HTTPAdapter.proxy_headers(). This should not be called directly, but improves the subclass interface.
  • httplib.IncompleteRead exceptions caused by incorrect chunked encoding will now raise a Requests ChunkedEncodingError instead.
  • Invalid percent-escape sequences now cause a Requests InvalidURL exception to be raised.
  • HTTP 208 no longer uses reason phrase "im_used". Correctly uses "already_reported".
  • HTTP 226 reason added ("im_used").

Bugfixes:

  • Vastly improved proxy support, including the CONNECT verb. Special thanks to the many contributors who worked towards this improvement.
  • Cookies are now properly managed when 401 authentication responses are received.
  • Chunked encoding fixes.
  • Support for mixed case schemes.

  • BytesIO can be used to perform streaming uploads.
  • More generous parsing of the no_proxy environment variable.
  • Non-string objects can be passed in data values alongside files.

1.2.0 (2013-03-31)
