The `ActionDispatch::Session::MemcacheStore` is still vulnerable
given it requires the gem dalli to be updated as well.

CVE-2019-16782

This reverts commit a077f94f.

That commit in Ruby that required those changes were reverted in
https://bugs.ruby-lang.org/projects/ruby-trunk/repository/git/revisions/8852fa876039ed177fd5e867f36177d8a9ff411c

I added myself links to the Ruby on Rails Tutorial years ago, after
meeting Michael in a RailsConf.

By then, the book was a commercial product, but had a free online
version and I thought it could be a good resource complementing the
official documentation.

Nowadays, only a few sample chapters are available for free, and I
don't consider these links to be fair with the rest of commercial
books about Rails anymore.

Symbol doesn't respond to `start_with?` so we need to change it to
string before doing the comparison.

This reverts commit 66c153c0.

Revert "Merge pull request #37839 from ttanimichi/modify-inspect-of-activesupport-duration-with-no-parts"

This reverts commit 01d7f82c.

Fix typo colection -> collection

This reverts commit 954d290a.

An app was reported to autoload in config/environments/development.rb,
and this is no longer possible with this change.

I believe it is a better trade-off to leave this for 6.1.

This reverts commit dede40ec.

Fix `since` and `ago` with a duration which has empty parts

The return value of `ActiveSupport::Duration#inspect` is wrong when its parts are empty

Backport of #37757
Co-authored-by: NChalo Fernandez <chalofa@gmail.com>

Check that entire collection has been loaded before short circuiting

Keep the example complex enough to showcase involving Action Mailers
to either: bounce and halt processing or finish the email processing
by asking for more information.

Improve deprecation message for leaking scope

See a4b47821 for more info.

Fixes #37441.

Thor will show a deprecation if a command fails and this method is not
define. We should investigate which command we want to return a non-zero
status when it fails but for now I'm just disabling the warning and
keeping the old behavior.
