This hack prevails everywhere in the codebase by being copy & pasted, and it's actually not a negative thing but a necessary thing for framework implementors,
so it should better have a name and be a thing.
And with this commit, activesupport/test/abstract_unit.rb now doesn't silently autoload AS::TestCase,
so we're ready to establish clearner environment for running AS tests (probably in later commits)
This fixes the following warnings.
```
actionmailer/test/base_test.rb:272: warning: method redefined; discarding old welcome
actionmailer/test/base_test.rb:260: warning: previous definition of welcome was here
```
Add missing bullet point to make clear this is
actually a separate option from
`:openssl_verify_mode`.
Add `:ssl/:tls`-option to guides as well [ci skip]
Without this change, `attachments.inline['my_attachment'].present?`, for example,
would raise the exception `Can't add attachments after mail was called`.
I first brought this issue up at https://github.com/rails/rails/issues/16163#issuecomment-437378347.
Note that this commit addresses only one of the 2 problems I described in that comment.
The other problem is that using `attachments.inline['my_attachment']` for reading an
attachment is unnecessary--it's the same as `attachments['my_attachment']`--even before
`mail` is called. We could add a warning about the unnecessary use of `inline` but I'm
saving that for a later PR since my comment has not received any feedback yet.
Previously this used self.formats= to set the format which render would
use to find templates. This worked, but was untested, and looked a
little confusing because it was doing the mutation within a loop.
This commit replaces the assignment with passing formats: [format] into
the render call, which makes it more obvious that that's the purpose of
the format. It also adds a test to verify the formats being used.
Templates only have one format. Before this commit, templates would be
constructed with a single element array that contained the format. This
commit eliminates the single element array and just implements a
`format` method. This saves one array allocation per template.
Since production applications typically run with log level info and
email adresses should be considered as sensitive data we want to prevent
them from ending up in the logs. In development mode (with log level
debug) they are still logged as part of the Mail::Message object.
Generally followed the pattern for https://github.com/rails/rails/pull/32034
* Removes needless CI configs for 2.4
* Targets 2.5 in rubocop
* Updates existing CHANGELOG entries for fewer merge conflicts
* Removes Hash#slice extension as that's inlined on Ruby 2.5.
* Removes the need for send on define_method in MethodCallAssertions.
- If a Mail defines a custom delivery_job, all ActionMailer assertion
helper (assert_emails, assert_enqueued_emails ...) wouldn't work.
```ruby
MyMailer < ApplicationMailer
self.delivery_job = MyJob
end
# This assertion will fail
assert_emails(1) do
MyMailer.my_mail.deliver_later
end
This PR leverage the new ActiveJob feature that accepts Procs for the
`only` keyword and check if the delivery job is one of ActionMailer
registered ones.
