| | | | | | | | | | | | | | | | * Use `gem 'redis', '~> 4.0'` for new app Gemfiles * Loosen Action Cable redis-rb dep to `>= 3.3, < 5` * Bump redis-namespace for looser Redis version dep * Avoid using the underlying `redis.client` directly * Use `Redis.new` instead of `Redis.connect`
* | Distinguish missing adapter gems from load errors within the adapterJeremy Daer2017-10-081-3/+16
|/ | | | | | | | * When the adapter is missing, raise an exception that points out config typos and missing Gemfile entries. (We can assume that a non-builtin adapter was used since these are always available.) * When loading an adapter raises a LoadError, prefix its error message to indicate that the adapter is likely missing an optional dependency.
* ActionCable: use find method when unsubscribingRichard Machielse2017-09-261-1/+1
| | | | | | | | | | If a frontend for some reason tries to unsubscribe from a non existing subscription, the following error is logged: Could not execute command from ({"command"=>"unsubscribe", "identifier"=>"{\"channel\":\"SomeChannel\"}"}) [NoMethodError - undefined method `unsubscribe_from_channel' for nil:NilClass] Instead, it will now properly log: Could not execute command from ({"command"=>"unsubscribe", "identifier"=>"{\"channel\":\"SomeChannel\"}"}) [RuntimeError - Unable to find subscription with identifier: {"channel":"SomeChannel"}]
* Clarify intentions around method redefinitionsMatthew Draper2017-09-011-0/+2
| | | | | | | | | Don't use remove_method or remove_possible_method just before a new definition: at best the purpose is unclear, and at worst it creates a race condition. Instead, prefer redefine_method when practical, and silence_redefinition_of_method otherwise.

* [ci skip] Prefer cookies.encrypted over signed (#30129)Claudio B2017-08-071-1/+1
| | | | | | | | | | | | | | | | In some examples and guides we are recommending to use code like: ```ruby verified_user = User.find_by(id: cookies.signed[:user_id]) ``` My suggestion is to use instead: ```ruby verified_user = User.find_by(id: cookies.encrypted[:user_id]) ``` which invites users to prefer the "newer" encrypted cookies over the "legacy" signed cookies.

* Allows for other common redis options to be in cable.yml, by defaultMarc Ignacio2017-06-221-1/+3
| | | | | | | | | | | | | | | | | | - Adds RedisAdapterTest::AlternateConfiguration to account for a relatively common alternative setup, as it’s used as the first example in the [Redis rubygem](https://github.com/redis/redis-rb#getting-started) - Supplies original RedisAdapterTest with more complete redis:// url format by adding a ‘userinfo’ (blank user), so that it resembles the alternate configuration - Supplies original EventedRedisAdapterTest with more complete redis:// url as well - Adds before_script to start redis-server with password as a daemon and with explicit defaults copied from the default redis.conf (Instead of using Travis' default init/upstart scripts for `redis` service)
* nodoc AC::Connection::WebSocketT.J. Schuck2017-06-161-1/+1
| | | | | Users should never publicly be interacting with an instance of this. The instance that comes along with an `AC::Connection::Base` instance (the only thing a user should be working with) is [itself intended to be private](https://github.com/tjschuck/rails/blob/master/actioncable/lib/action_cable/connection/base.rb#L137-L140).

| | | | | | | This method is repeatedly used throughout the docs (in the [AC::Connection docs](https://github.com/rails/rails/blob/12b684985837bc8ee9ad15c174cf4e07ca82d7c4/actioncable/lib/action_cable/connection/base.rb#L28), the [AC README](https://github.com/rails/rails/blob/12b684985837bc8ee9ad15c174cf4e07ca82d7c4/actioncable/README.md#a-full-stack-example), the [AC Guides](https://github.com/rails/rails/blob/12b684985837bc8ee9ad15c174cf4e07ca82d7c4/guides/source/action_cable_overview.md#connection-setup)), but not actually documented itself and seemingly not supported for public use based on its current `private` status. This actually makes the method public and documents it. The actual behavior that’s documented here is implemented [here](https://github.com/rails/rails/blob/12b684985837bc8ee9ad15c174cf4e07ca82d7c4/actioncable/lib/action_cable/connection/base.rb#L213-L219), via [this rescuing of the UnauthorizedError](https://github.com/rails/rails/blob/3dd1de8ba4d5862b01e7f5dd3878b21fd98b443b/actioncable/lib/action_cable/connection/base.rb#L172). The method is [already tested here](https://github.com/rails/rails/blob/25473baf409185638073fe2f016f4b9dda284e50/actioncable/test/connection/authorization_test.rb#L17-L29).

* `self.` is not needed when calling its own instance methodAkira Matsuda2017-01-052-3/+3
| | | | Actually, private methods cannot be called with `self.`, so it's not just redundant, it's a bad habit in Ruby

* Add more rubocop rules about whitespacesRafael Mendonça França2016-10-294-4/+4

* Permit same-origin connections by defaultMatthew Draper2016-10-112-3/+3
| | | | | | | | | | | | | | | | | WebSocket always defers the decision to the server, because it didn't have to deal with legacy compatibility... but the same-origin policy is still a reasonable default. Origin checks do not protect against a directly connecting attacker -- they can lie about their host, but can also lie about their origin. Origin checks protect against a connection from 3rd-party controlled script in a context where a victim browser's cookies will be passed along. And if an attacker has breached that protection, they've already compromised the HTTP session, so treating the WebSocket connection in the same way seems reasonable. In case this logic proves incorrect (or anyone just wants to be more paranoid), we retain a config option to disable it.

|\ | | | | | | Optionally allow ActionCable requests from the same host as origin
| * Optionally allow ActionCable requests from the same host as originDávid Halász2016-09-212-1/+5
| | | | | | | | | | | | | | When the `allow_same_origin_as_host` is set to `true`, the request forgery protection permits `HTTP_ORIGIN` values starting with the corresponding `proto://` prefix followed by `HTTP_HOST`. This way it is not required to specify the list of allowed URLs.
* | Close the IO from the read loop threadMatthew Draper2016-10-062-1/+1
| | | | | | | | | | | | | | | | IO#close and IO#read across threads don't get along so well: After T1 enters #read and releases the GVL, T2 can call #close on the IO, thereby both closing the fd and freeing the buffer while T1 is using them.
* | Shut down the worker pool - don't kill itMatthew Draper2016-10-031-1/+1
| | | | | | | | | | Different parts of concurrent-ruby's documentation make inconsistent claims about how kill will behave. It doesn't do the thing we want.

* | Shutdown pubsub connection before classes are reloadedJon Moss2016-10-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Before this patch, if you were to make a file edit in your Rails application and you tried to load up the page, it would hang indefinitely. The issue is that Active Record is trying to cleanup after itself and clear all active connection, but Action Cable is still holding onto a connection from the pool. To resolve this, we are now shutting down the pubsub adapter before classes are reloaded, to avoid this altogether (connection is being returned to the pool). Credits to @skateman for discovering this bug. :)
