The old implementation sets default From address in mailers. It sets
the address from SMTP_FROM_ADDRESS, or notifications@localhost. The
behavior is occasionally undesired results.

In production environment, notifications@localhost is likely to be
incorrect.
In testing environment, the email address should not be varied by a
environment variable.

After appling this change,

In production environment, it will throw an exception when launching
Mastodon.
In testing environment, the address will be fixed with
notifications@localhost.

* Support multiple trusted proxy ip addresses

* correct coding style

* Update rails to version 5.1.1

* Run `rails app:update`

* Remove the override of polymorphic activity relationship

* Silence warning about otp_secret attribute being unknown to rails

* We will only introduce form_with where we want to use remote data

* Set config.cache_store in application.rb

* Set config.cache_store in environments.

* fix code format.

* Fix Scheduler::SubscriptionsScheduler, add worker test for it

* Change production log level of Sidekiq to "warn" instead of "info"

* Fix #2473 - Use sidekiq scheduler to refresh PuSH subscriptions instead of cron

Fix an issue where / in domain would raise exception in TagManager#normalize_domain

PuSH subscriptions refresh done in a round-robin way to avoid hammering a single
server's hub in sequence. Correct handling of failures/retries through Sidekiq (see
also #2613). Optimize Account#with_followers scope. Also, since subscriptions
are now delegated to Sidekiq jobs, an uncaught exception will not stop the entire
refreshing operation halfway through

Fix #2702 - Correct user agent header on outgoing http requests

* Add test for SubscribeService

* Extract #expiring_accounts into method

* Make mastodon:push:refresh no-op

* Queues are now defined in sidekiq.yml

* Queues are now in sidekiq.yml

connection options instead of setting REDIS_HOST etc individually

Close #1986

* Replace browserify with webpack

* Add react-intl-translations-manager

* Do not minify in development, add offline-plugin for ServiceWorker background cache updates

* Adjust tests and dependencies

* Fix production deployments

* Fix tests

* More optimizations

* Improve travis cache for npm stuff

* Re-run travis

* Add back support for custom.scss as before

* Remove offline-plugin and babili

* Fix issue with Immutable.List().unshift(...values) not working as expected

* Make travis load schema instead of running all migrations in sequence

* Fix missing React import in WarningContainer. Optimize rendering performance by using ImmutablePureComponent instead of
React.PureComponent. ImmutablePureComponent uses Immutable.is() to compare props. Replace dynamic callback bindings in
<UI />

* Add react definitions to places that use JSX

* Add Procfile.dev for running rails, webpack and streaming API at the same time

The force_ssl method from controllers does not add all of the options that the
sitewide configuration in a config block does. For example, HSTS enforcement is
not added by the controller method, but is added by this style.

* Allow using an SMTP server without authentication (e.g Postfix relay on the same host) by setting SMTP_LOGIN and SMTP_AUTH_METHOD to 'none'

* Add note in .env.production.sample about SMTP settings for servers where no auth is required

* Assume that SMTP_LOGIN and SMTP_PASSWORD will be blank if we set SMTP_AUTH_METHOD to none

* delivery fix

# Conflicts:
#	config/environments/production.rb

* added stub in .env file

* reordered and added a comment

* Allow SMTP auth method customization

* Add SMTP openssl_verify_mode option support

Allows one use self-signed certs with their SMTP server.

* Add SMTP enable_starttls_auto option support

* Allows setting log level in env variable.

* Made changes based on feedback in #1290.

can be processed separately

during Fan Out On Write to load less stuff into memory

to be more readable, add extra logging to process feed service

footprint of each running process by 128mb

production as it's very verbose and not very useful

Added stack trace for SQL queries in development
Removed badly thought out accounts/lookup API
