[3.1.0] - 2024-06-11¶ ↑

:warning: This release includes several breaking changes. Refer to the Removed section below for the list of deprecated methods that have been removed in this release.

Rack v3.1 is primarily a maintenance release that removes features deprecated in Rack v3.0. Alongside these removals, there are several improvements to the Rack SPEC, mainly focused on enhancing input and output handling. These changes aim to make Rack more efficient and align better with the requirements of server implementations and relevant HTTP specifications.

SPEC Changes¶ ↑

• Introduce optional rack.protocol request and response header for handling connection upgrades. (#1954, @ioquatix)

Added¶ ↑

• Introduce Rack::Multipart::MissingInputError for improved handling of missing input in parse_multipart. (#2018, @ioquatix)

• Introduce module Rack::BadRequest which is included in multipart and query parser errors. (#2019, @ioquatix)

Deprecated¶ ↑

• Deprecate automatic cache invalidation in Request#{GET,POST} (#2073, @jeremyevans)

• Only cookie keys that are not valid according to the HTTP specifications are escaped. We are planning to deprecate this behaviour, so now a deprecation message will be emitted in this case. In the future, invalid cookie keys may not be accepted. (#2191, @ioquatix)

• Response status must now be an integer greater than or equal to 100.

• Response headers must now be an unfrozen hash.

• Response header keys can no longer include uppercase characters.

• Response header values can be an Array to handle multiple values (and no longer supports \n encoded headers).

• Response body can now respond to call (streaming body) instead of each (enumerable body), for the equivalent of response hijacking in previous versions.

• Middleware must no longer call each on the body, but they can call to_ary on the body if it responds to to_ary.

• rack.input is no longer required to be rewindable.

• rack.multithread/rack.multiprocess/rack.run_once/rack.version are no longer required environment keys.

• SERVER_PROTOCOL is now a required environment key, matching the HTTP protocol used in the request.

• rack.hijack? (partial hijack) and rack.hijack (full hijack) are now independently optional.

• rack.hijack_io has been removed completely.

• rack.response_finished is an optional environment key which contains an array of callable objects that must accept call(env, status, headers, error) and are invoked after the response is finished (either successfully or unsuccessfully).

• It is okay to call close on rack.input to indicate that you no longer need or care about the input.

• The stream argument supplied to the streaming body and hijack must support << for writing output.

Removed¶ ↑

• Remove rack.multithread/rack.multiprocess/rack.run_once. These variables generally come too late to be useful. (#1720, @ioquatix, @jeremyevans))

• Remove internal cookie deletion using pattern matching, there are very few practical cases where it would be useful and browsers handle it correctly without us doing anything special. (#1844, @ioquatix)

• Remove rack.version as it comes too late to be useful. (#1938, @ioquatix)

• Extract rackup command, Rack::Server, Rack::Handler, Rack::Lobster and related code into a separate gem. (#1937, @ioquatix)

• Rack::RewindableInput::Middleware added for making rack.input rewindable. (@jeremyevans)

• The RFC 7239 Forwarded header is now supported and considered by default when looking for information on forwarding, falling back to the X-Forwarded-* headers. Rack::Request.forwarded_priority accessor has been added for configuring the priority of which header to check. (#1423, @jeremyevans)

• Allow response headers to contain array of values. (#1598, @ioquatix)

• Support callable body for explicit streaming support and clarify streaming response body behaviour. (#1745, @ioquatix, #1748, @wjordan)

• Rack::Request.forwarded_authority (and methods that call it, such as host) now returns the last authority in the forwarded header, instead of the first, as earlier forwarded authorities can be forged by clients. This restores the Rack 2.1 behavior. (#1829, @jeremyevans)

• Use lower case cookie attributes when creating cookies, and fold cookie attributes to lower case when reading cookies (specifically impacting secure and httponly attributes). (#1849, @ioquatix)

History/News Archive¶ ↑

Items below this line are from the previously maintained HISTORY.md and NEWS.md files.

[2.0.0.rc1] 2016-05-06¶ ↑

• Rack::Session::Abstract::ID is deprecated. Please change to use Rack::Session::Abstract::Persisted

[2.0.0.alpha] 2015-12-04¶ ↑

• First-party “SameSite” cookies. Browsers omit SameSite cookies from third-party requests, closing the door on many CSRF attacks.

• Pass same_site: true (or :strict) to enable: response.set_cookie ‘foo’, value: ‘bar’, same_site: true or same_site: :lax to use Lax enforcement: response.set_cookie ‘foo’, value: ‘bar’, same_site: :lax

• Based on version 7 of the Same-site Cookies internet draft: tools.ietf.org/html/draft-west-first-party-cookies-07

• Thanks to Ben Toews (@mastahyeti) and Bob Long (@bobjflong) for updating to drafts 5 and 7.

• Add Rack::Events middleware for adding event based middleware: middleware that does not care about the response body, but only cares about doing work at particular points in the request / response lifecycle.

• Add Rack::Request#authority to calculate the authority under which the response is being made (this will be handy for h2 pushes).

• Add Rack::Response::Helpers#cache_control and cache_control=. Use this for setting cache control headers on your response objects.

• Add Rack::Response::Helpers#etag and etag=. Use this for setting etag values on the response.

• Introduce Rack::Response::Helpers#add_header to add a value to a multi-valued response header. Implemented in terms of other Response#*_header methods, so it’s available to any response-like class that includes the Helpers module.

• Add Rack::Request#add_header to match.

• Rack::Session::Abstract::ID IS DEPRECATED. Please switch to Rack::Session::Abstract::Persisted. Rack::Session::Abstract::Persisted uses a request object rather than the env hash.

• Pull ENV access inside the request object in to a module. This will help with legacy Request objects that are ENV based but don’t want to inherit from Rack::Request

• Move most methods on the Rack::Request to a module Rack::Request::Helpers and use public API to get values from the request object. This enables users to mix Rack::Request::Helpers in to their own objects so they can implement (get|set|fetch|each)_header as they see fit (for example a proxy object).

• Files and directories with + in the name are served correctly. Rather than unescaping paths like a form, we unescape with a URI parser using Rack::Utils.unescape_path. Fixes #265

• Tempfiles are automatically closed in the case that there were too many posted.

• Added methods for manipulating response headers that don’t assume they’re stored as a Hash. Response-like classes may include the Rack::Response::Helpers module if they define these methods:

  • Rack::Response#has_header?

    • Rack::Response#get_header

    • Rack::Response#set_header

    • Rack::Response#delete_header

• Introduce Util.get_byte_ranges that will parse the value of the HTTP_RANGE string passed to it without depending on the env hash. byte_ranges is deprecated in favor of this method.

• Change Session internals to use Request objects for looking up session information. This allows us to only allocate one request object when dealing with session objects (rather than doing it every time we need to manipulate cookies, etc).

• Add Rack::Request#initialize_copy so that the env is duped when the request gets duped.

• Added methods for manipulating request specific data. This includes data set as CGI parameters, and just any arbitrary data the user wants to associate with a particular request. New methods: - Rack::Request#has_header? - Rack::Request#get_header - Rack::Request#fetch_header - Rack::Request#each_header - Rack::Request#set_header - Rack::Request#delete_header

• lib/rack/utils.rb: add a method for constructing “delete” cookie headers. This allows us to construct cookie headers without depending on the side effects of mutating a hash.

• Prevent extremely deep parameters from being parsed. CVE-2015-3225

[1.6.1] 2015-05-06¶ ↑
