ActiveModel::Type)

Some code was previously referring to ActiveModel::Type::*. This could
cause issues in the future if any of the ActiveRecord::Type classes were
overridden in the future.

Allow the use of listen's 3.1.x branch.

When the initial evented monitor feature was written, the latest version of listen
was the 3.0.x series. Since then the listen project has moved on to the 3.1.x series.
This patch allows the use of the new versions.

Show an "unmatched constraints" error when params fail to match constraints

Currently a misleading "missing required keys" error is thrown when a param
fails to match the constraints of a particular route. This commit ensures that
these params are recognised as unmatching rather than missing.

Note: this means that a different error message will be provided between
optimized and non-optimized path helpers, due to the fact that the former does
not check constraints when matching routes.

Fixes #26470.

Fix issue with `cache_key` when the named timestamp column has value nil

Different parts of concurrent-ruby's documentation make inconsistent
claims about how kill will behave. It doesn't do the thing we want.

Shutdown pubsub connection before classes are reloaded

In #25880 we tried to cache localtime to fix the performance
regression but that proved to be difficult due to the fact that
localtime/getlocal can take a utc_offset argument. We tried
caching based on the argument but since the argument can be nil
sometimes that meant that if the TZ environment variable changed
then the cached value for nil became invalid. By moving the
caching to DateAndTime#compatibility we don't have to worry about
arguments since it doesn't take any.

There is a possible edge condition where preserve_timezone is set
to false and the system timezone changes then it could result in
a cached value being incorrect but the only way to fix this would
be to remove all caching and live with the performance issue.

Turns out trying to cache on localtime with arguments is too hard
so we'll do it on DateAndTime::Compatibility#to_time instead.

This reverts commit 3132fa6b, reversing
changes made to 6949f8e5.

Before this patch, if you were to make a file edit in your Rails
application and you tried to load up the page, it would hang
indefinitely. The issue is that Active Record is trying to cleanup after
itself and clear all active connection, but Action Cable is still
holding onto a connection from the pool. To resolve this, we are now
shutting down the pubsub adapter before classes are reloaded, to avoid
this altogether (connection is being returned to the pool).

Avoid compiling ruby keywords into template locals

this lets you pass ruby keywords to templates:

    <%= render 'example', class: "cool" %>

    <%= render 'example', "spaces are" => "a-ok" %>

    <%= render 'example', Foo: "bar" %>

Previously you'd see confusing syntax errors like this:

    SyntaxError (.../_example.html.erb:1: syntax error, unexpected '='

Now you can reference invalid identifiers through local_assigns.

If you try to use an invalid keyword (e.g. class) in your template, you
get a syntax error on the line where you use it.

Use websocket-client-simple instead of Faye in tests

Mostly, this is just to avoid EventMachine. But there's also an argument
to be made that we're better off using a different protocol library for
our test suite than the one we use to implement the server.

Fix `ActiveSupport::TimeWithZone#localtime`

Add missing require for zlib in ActiveRecord::Migrator

Zlib is used to generate the advisory lock since commit 2c2a8755 .

Using the Migrator fails since then, when it is called without the rails context:

    NameError: uninitialized constant ActiveRecord::Migrator::Zlib

This patch fixes the above error.

Previously memoization in `localtime` wasn't taking the `utc_offset`
parameter into account when returning a cached value. It now caches the
computed value depending on the `utc_offset` parameter, e.g:

    Time.zone = "US/Eastern"

    t = Time.zone.local(2016,5,2,11)
    # => Mon, 02 May 2016 11:00:00 EDT -04:00

    t.localtime(-7200)
    # => 2016-05-02 13:00:00 -0200

    t.localtime(-3600)
    # => 2016-05-02 14:00:00 -0100

Remove Faye mode

We've seen occasional Travis failures mentioning deadlocks. I think
they're escaping from this test.

No deprecation, because it was never documented.
