* Enable `Style/RedundantBegin` cop to avoid newly adding redundant begin blockRyuta Kamizono2018-12-211-7/+5
| | | | | | | | | | Currently we sometimes find a redundant begin block in code review (e.g. https://github.com/rails/rails/pull/33604#discussion_r209784205). I'd like to enable `Style/RedundantBegin` cop to avoid that, since rescue/else/ensure are allowed inside do/end blocks in Ruby 2.5 (https://bugs.ruby-lang.org/issues/12906), so we'd probably meets with that situation than before.

* 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.

* Permit same-origin connections by defaultMatthew Draper2016-10-111-1/+1
| | | | | | | | | | | | | | | | | 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 originDávid Halász2016-09-211-1/+2
| | | | | | | | | | | | | | 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.
* | 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.

* Cable: Extract stream handler constructionJeremy Daer2016-04-181-8/+10
| | | | | | | | * Use separate stream handler builders for easy override and testing. * Fix worker pool execution that was silently failing since it only expected connection receivers. Sparked by code in #24162.

* Cable message encodingJeremy Daer2016-03-311-9/+10
| | | | | | | | | | | | | | | | | | | * Introduce a connection coder responsible for encoding Cable messages as WebSocket messages, defaulting to `ActiveSupport::JSON` and duck- typing to any object responding to `#encode` and `#decode`. * Consolidate encoding responsibility to the connection. No longer explicitly JSON-encode from channels or other sources. Pass Cable messages as Hashes to `#transmit` and rely on it to encode. * Introduce stream encoders responsible for decoding pubsub messages. Preserve the currently raw encoding, but make it easy to use JSON. Same duck type as the connection encoder. * Revert recent data normalization/quoting (#23649) which treated `identifier` and `data` values as nested JSON objects rather than as opaque JSON-encoded strings. That dealt us an awkward hand where we'd decode JSON strings… or not, but always encode as JSON. Embedding JSON object values directly is preferably, no extra JSON encoding, but that should be a purposeful protocol version change rather than ambiguously, inadvertently supporting multiple message formats.
* Cable: reconcile default worker pool size with low db conn pool sizeJeremy Daer2016-03-302-2/+12
| | | | | | | | | | | Whack it down from 100 to 4. Large worker pools means large db connection counts. We aren't set up for that by default and most apps won't need it out of the box. We're better off tuning the default worker pool for low traffic, low resource consumption apps. Those who have higher traffic will scale up to meet demand.

| | | | | | | | | | | | Similar to the channel streaming side, these values must be strings for ActionCable to behave as expected. The conversion will allow users to send string-convertible values and get the expected behavior.

| | | | | | | | | | | | | | Instead of depending on ApplicationCable::Connection being defined at initialize we should inject it in the Railtie. Thus we can kill more setup in the tests too.
| * Inject Rails' channel paths in engine.Kasper Timm Hansen2016-02-141-9/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | We were explicitly referencing Rails.root in ActionCable::Server::Configuration.initialize, thereby coupling ourselves to Rails. Instead add `app/channels` to Rails' app paths and assign the existent files to `channel_paths`. Users can still append to those load paths with `<<` and `push` in `config/application.rb`. This means we can remove the custom `Dir` lookup in `channel_paths` and the Rails and root definitions in the tests.
