:update_details method no more exists on @lookup_context

Async actionmailer

the method has gone in this commit: 119e9e2d

Try to use more destructive methods on *args when applicable, to avoid
creating new objects.

exists?(false) returns false

Fix build issue with postgresql.

Missing require breaks Time.=== when selectively loading ActiveSupport core_exts in 3.2.4+

If you selectively require core_exts (e.g., require
'active_support/core_ext/string'), it is possible for
'active_support/core_ext/time/calculations' to be required when
`ActiveSupport::TimeWithZone` is not available. If this happens, the next call
to Time.=== will fail with a NameError.

Refactor and improve database tasks.

add :nodoc: to internal implementations [ci skip]

These _define class methods don't need to be exposed to objects that
extend ActiveModel::Callbacks.

Also use merge! options to avoid the creation of an extra hash.

`FinderMethods#exists?` finder method now returns *false* with the *false* argument

This commit needs to be reverted because it introduces difficulties when
using sqlite3 in development and other databases in production. This
happens because when you create time column in sqlite3, it's dumped as
datetime in schema.rb file.

This reverts commit 57d534ee, reversing
changes made to 20f049fb.

Refactor and improve a bit number helpers code.

Use a different and very specific locale for testing currency negative
format, and an empty store for currency defaults.

They also make more sense here since all the related logic with I18n is
handled by AS::NumberHelper, and not by AV anymore.

Just make use of the returning exception from assert_raise, instead of
calling the method again with a rescue clause to test the saved
exception number.

ActiveSupport::NumberHelper does not make use of :raise, so there's no
need to propagate it down.

Correct line numbers for reader and writer methods in AS configurable

The line number for the reader method is off by one due to the local variable line being reassigned to the writer's line.

This commit would provide correct line numbers for backtraces and method introspection (for example, method(:reader).source_location).

Stop assuming strings for grouped calculations

Execute_grouped_calculation is one of those places where
ActiveRecord forgets that it has ARel underpinnings, and
assumes that the values provided to group_values are
strings. This artificially hobbles otherwise functional
code. This patch stops assuming that incoming values
respond to to_sym, stops using string interpolation for
table aliases on objects that support aliasing, and stops
unnecessarily joining group_values on the relation.

Additionally, it calls to_sql, if available, on objects
sent to column_alias_for, in order to get a more reasonable
alias string than a non-string's default to_str method.
