WebOb 1.5.0b0

WSGI request and response object

WebOb provides objects for HTTP requests and responses. Specifically it does this by wrapping the WSGI request environment and response status/headers/app_iter(body).

The request and response objects provide many conveniences for parsing HTTP request and forming HTTP responses. Both objects are read/write: as a result, WebOb is also a nice way to create HTTP requests and parse HTTP responses.

1.5.0b0 (2015-09-06)

Bug Fixes

• Unbreak req.POST when the request method is PATCH. Instead of returning something cmpletely unrelated we return NoVar. See: https://github.com/Pylons/webob/pull/215

Features

• HTTP Status Code 308 is now supported as a Permanent Redirect. See https://github.com/Pylons/webob/pull/207

1.5.0a1 (2015-07-30)

Backwards Incompatibilities

• Response.set_cookie renamed the only required parameter from “key” to “name”. The code will now still accept “key” as a keyword argument, and will issue a DeprecationWarning until WebOb 1.7.

• The status attribute of a Response object no longer takes a string like None None and allows that to be set as the status. It now has to at least match the pattern of <integer status code> <explenation of status code>. Invalid status strings will now raise a ValueError.

1.5.0a0 (2015-07-25)

Backwards Incompatibilities

• Morsel will no longer accept a cookie value that does not meet RFC6265’s cookie-octet specification. Upon calling Morsel.serialize a warning will be issued, in the future this will raise a ValueError, please update your cookie handling code. See https://github.com/Pylons/webob/pull/172

  The cookie-octet specification in RFC6265 states the following characters are valid in a cookie value:

  Hex Range	Actual Characters
  [0x21 ]	!
  [0x25-0x2B]	#$%&'()*+
  [0x2D-0x3A]	-./0123456789:
  [0x3C-0x5B]	<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[
  [0x5D-0x7E]	]^_`abcdefghijklmnopqrstuvwxyz{|}~

  RFC6265 suggests using base 64 to serialize data before storing data in a cookie.

  Cookies that meet the RFC6265 standard will no longer be quoted, as this is unnecessary. This is a no-op as far as browsers and cookie storage is concerned.

• Response.set_cookie now uses the internal make_cookie API, which will issue warnings if cookies are set with invalid bytes. See https://github.com/Pylons/webob/pull/172

Features

• Add support for some new caching headers, stale-while-revalidate and stale-if-error that can be used by reverse proxies to cache stale responses temporarily if the backend disappears. From RFC5861. See https://github.com/Pylons/webob/pull/189

Bug Fixes

• Response.status now uses duck-typing for integers, and has also learned to raise a ValueError if the status isn’t an integer followed by a space, and then the reason. See https://github.com/Pylons/webob/pull/191

• Fixed a bug in webob.multidict.GetDict which resulted in the QUERY_STRING not being updated when changes were made to query params using Request.GET.extend().

• Read the body of a request if we think it might have a body. This fixes PATCH to support bodies. See https://github.com/Pylons/webob/pull/184

• Response.from_file returns HTTP headers as latin1 rather than UTF-8, this fixes the usage on Google AppEngine. See https://github.com/Pylons/webob/issues/99 and https://github.com/Pylons/webob/pull/150

• Fix a bug in parsing the auth parameters that contained bad white space. This makes the parsing fall in line with what’s required in RFC7235. See https://github.com/Pylons/webob/issues/158

• Use ‘rn’ line endings in Response.__str__. See: https://github.com/Pylons/webob/pull/146

Documentation Changes

• response.set_cookie now has proper documentation for max_age and expires. The code has also been refactored to use cookies.make_cookie instead of duplicating the code. This fixes https://github.com/Pylons/webob/issues/166 and https://github.com/Pylons/webob/issues/171

• Documentation didn’t match the actual code for the wsgify function signature. See https://github.com/Pylons/webob/pull/167

• Remove the WebDAV only from certain HTTP Exceptions, these exceptions may also be used by REST services for example.
