because of an ambiguous column name. This happened if the association
model had a default scope that referenced a third table, and the third
table also referenced the original table (with an identical
foreign_key).
Mysql requires that ambiguous columns are deambiguated by using the full
table.column syntax. Postgresql and Sqlite use a different syntax for
updates altogether (and don't tolerate table.name syntax), so the fix
requires always including the full table.column and discarding it later
for Sqlite and Postgresql.

If we set encoding latin1 for a PostgreSQL database, it calls
PostgreSQLAdapter::create_database with options that have,
among other things:
{ 'encoding' => 'latin1' }
Then, we use reverse_merge(:encoding => "utf8") to setup the default
encoding. In the end, the hash looks like:
{ :encoding => 'utf8', 'encoding' => 'latin1' }
The call to options.symbolize_keys calls to_sym on each_key of this
Hash. It usually means that the encoding passed overwrites the default
utf8, but it's not guaranteed. So, we shouldn't rely on it.
The same was happening in ActiveRecord::ConnectionHandling.

Also covers any non-castable case by returning nil, which
is in-line with the intention of the former implementation,
but covers the odd cases which respond to to_i but raise
an error when it's called, such as NaN, Infinity and -Infinity.

This commit fixes a bug introduced in 96a13fc7 which breaks behaviour of
integer fields.
In 3.2.8, setting the value of an integer field to a non-integer (eg.
Array, Hash, etc.) would default to 1 (true) :
# 3.2.8
p = Post.new
p.category_id = [ 1, 2 ]
p.category_id # => 1
p.category_id = { 3 => 4 }
p.category_id # => 1
In 3.2.9 and above, this will raise a NoMethodError :
# 3.2.9
p = Post.new
p.category_id = [ 1, 2 ]
NoMethodError: undefined method `to_i' for [1, 2]:Array
Whilst at first blush this appear to be sensible, it combines in bad
ways with scoping.
For example, it is common to use scopes to control access to data :
@collection = Posts.where(:category_id => [ 1, 2 ])
@new_post = @collection.new
In 3.2.8, this would work as expected, creating a new Post object
(albeit with @new_post.category_id = 1). However, in 3.2.9 this will
cause the NoMethodError to be raised as above.
It is difficult to avoid triggering this error without descoping before
calling .new, breaking any apps running on 3.2.8 that rely on this
behaviour.
This patch deviates from 3.2.8 in that it does not retain the somewhat
spurious behaviour of setting the attribute to 1. Instead, it explicitly
sets these invalid values to nil :
p = Post.new
p.category_id = [ 1, 2 ]
p.category_id # => nil
This also fixes the situation where a scope using an array will
"pollute" any newly instantiated records.
@new_post = @collection.new
@new_post.category_id # => nil
Finally, 3.2.8 exhibited a behaviour where setting an object to an
integer field caused it to be coerced to "1". This has not been
retained, as it is spurious and surprising in the same way that setting
Arrays and Heshes was :
c = Category.find(6)
p = Post.new
# 3.2.8
p.category_id = c
p.category_id # => 1
# This patch
p.category_id = c
p.category_id # => nil
This commit includes explicit test cases that expose the original issue
with calling new on a scope that uses an Array. As this is a common
situation, an explicit test case is the best way to prevent regressions
in the future.
It also updates and separates existing tests to be explicit about the
situation that is being tested (eg. AR objects vs. other objects vs.
non-integers)

Summary of the changes:
* Add thread_safe gem.
* Use thread safe cache for digestor caching.
* Replace manual synchronization with ThreadSafe::Cache in Relation::Delegation.
* Replace @attribute_method_matchers_cache Hash with ThreadSafe::Cache.
* Use TS::Cache to avoid the synchronisation overhead on listener retrieval.
* Replace synchronisation with TS::Cache usage.
* Use a preallocated array for performance/memory reasons.
* Update the controllers cache to the new AS::Dependencies::ClassCache API.
The original @controllers cache no longer makes much sense after @tenderlove's
changes in 7b6bfe84f3 and f345e2380c.
* Use TS::Cache in the connection pool to avoid locking overhead.
* Use TS::Cache in ConnectionHandler.

The Time.time_with_datetime_fallback, Time.utc_time and Time.local_time
methods were added to handle the limitations of Ruby's native Time
implementation. Those limitations no longer apply so we are deprecating
them in 4.0 and they will be removed in 4.1.

Keying these hashes by klass causes reloadable classes to never get

the comments on 221571beb6b4bb7437989bdefaf421f993ab6002.
This doesn't seem to make a massive difference to performance.
