The PR #13767 added link to the upgrading guide to explain
details about activerecord_deprecated-finders. However the link target
features a stack of changes not releated at all. Also the relevant details
are not very informative.
I think we better link to the README so people can see what the gem is about
and how to use it.

This fixes a regression (#13744) that was caused by 67d8bb9.
In 67d8bb9, we introduced lazy rollback for records, such that the
record's internal states and attributes are not restored immediately
after a transaction rollback, but deferred until they are first
accessed.
This optimization is only performed when the model does not have any
transactional callbacks (e.g. `after_commit` and `after_create`).
Unfortunately, the models used to test the affected codepaths all
comes with some sort of transactional callbacks. Therefore this
codepath remains largely untested until now and as a result there are
a few issues in the implementation that remains hidden until now.
First, the `sync_with_transaction_state` (or more accurately,
`update_attributes_from_transaction_state`) would perform the
synchronization prematurely before a transaction is finalized (i.e.
comitted or rolled back). As a result, when the actuall rollback
happens, the record will incorrectly assumes that its internal states
match the transaction state, and neglect to perform the restore.
Second, `update_attributes_from_transaction_state` calls `committed!`
in some cases. This in turns checks for the `destroyed?` state which
also requires synchronization with the transaction stae, which causes
an infnite recurrsion.
This fix works by deferring the synchronization until the transaction
has been finalized (addressing the first point), and also unrolled
the `committed!` and `rolledback!` logic in-place (addressing the
second point).
It should be noted that the primary purpose of the `committed!` and
`rolledback!` methods are to trigger the relevant transactional
callbacks. Since this code path is only entered when there are no
transactional callbacks on the model, this shouldn't be necessary. By
unrolling the method calls, the intention here (to restore the states
when necessary) becomes more clear.
This change breaks tests in activesupport/test/core_ext/module_test.rb:
* test_delegation_exception_backtrace
* test_delegation_exception_backtrace_with_allow_nil
This reverts commit 0167765e3f84260522bc2f32d926c1f5dd44957c.
The revert is needed because of a regression described in #13369, routes
with trailing slash are no longer recognized properly.
This reverts commit 50311f1391ddd8e0349d74eb57f04b7e0045a27d.
After introducing 50311f1 a regression was introduced: routes with
trailing slash are no longer recognized properly. This commit provides a
failing test for this situation.
This gets the whole Active Record suite working without calling
`self.i_suck_and_my_tests_are_order_dependent!` on `ActiveSupport::TestCase`.
Note that the test files themselves still run in order. This means
that only order dependencies within a single test file were addressed.
