The driver being used is an implementation detail of `redis-rb`.
If somehow something break on one driver but not the other, it should
be reported to redis-rb and fixed there.
Also `redis-rb` `5.0` has a totally new client and hiredis binding
so all this code no longer works with redis-rb 5.0.
* You can distinguish connection among others with specific `application_name`
```sql
SELECT application_name FROM pg_stat_activity;
/*
application_name
------------------------
psql
ActionCable-PID-42
(2 rows)
*/
```
* It's possible to customize connection identification with `id` option in `cable.yml`
`ActionCable-PID-#{$$}` is the default value
* Related tests refactoring
* `ActionCable::Server#config.cable` is no mutated anymore inside Redis subscription adapter
Remove all `include ActiveSupport::Testing::MethodCallAssertions`
in actioncable's tests since we can do it only in `ActionCable::TestCase`
in order to prevent code duplication.
We use the same approach for other modules of Rails.
We have defined `ActionCable::TestCase` in `actioncable/test/test_helper.rb`
that we can use in order to prevent code duplication and build common
interface for actioncable's test.
Simplify our dev testing and CI story since we're also testing against
Redis for the Active Support cache store.
Directly test whether db, host, password, etc are passed through as
config instead of spinning up a Redis server with a password set on it.
- 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)
This new adapter does get a little more intimate with the redis-rb gem's
implementation than I would like, but it's the least bad of the
approaches I've come up with.
