Apply schema cache dump when creating connections

The `db:schema:cache:dump` rake task dumps the database schema structure
to `db/schema_cache.dump`. If this file is present, the schema details
are loaded into the currently checked out connection by a railtie while
Rails is booting, to avoid having to query the database for its schema.
The schema cache dump is only applied to the initial connection used to
boot the application though; other connections from the same pool are
created with an empty schema cache, and still have to load the structure
of each table directly from the database.
With this change, a copy of the schema cache is associated with the
connection pool and applied to connections as they are created.

Nodoc validate_index_length! method
|
| |/
| |
| |
| | |
- This method is used only by adapters to validate length of new index names.

- Added documentation for index_name_exists? and rename_index.
- Also changed rails to \Rails in documentation of
allowed_index_name_length.

The `index` option used with `timestamps` should be passed to both
`column` definitions for `created_at` and `updated_at` rather than just
the first.
This was happening because `Hash#delete` is used to extract the `index`
option passed to `timestamps`, thereby mutating the `options` hash
in-place. Now take a copy of the `options` before deleting so that the
original is not modified.

We should document current behavior, and this is design of API for now.

The implementation of the generation of the foreign key name was changed
between Rails 4.2.0 and 4.2.1 from a random to a deterministic behavior,
however the documentation still describes the old randomized behavior.

https://github.com/ruby/ruby/pull/579 - there is a new optimization
since ruby 2.2
Previously regexp patterns were faster (since a string was converted to
regexp underneath anyway). But now string patterns are faster and
better reflect the purpose.
Benchmark.ips do |bm|
bm.report('regexp') { 'this is ::a random string'.gsub(/::/, '/') }
bm.report('string') { 'this is ::a random string'.gsub('::', '/') }
bm.compare!
end
# string: 753724.4 i/s
# regexp: 501443.1 i/s - 1.50x slower

This reverts commit a38732c8e6ab76ea0db4e1a617a1fa84b53a9750.
Since the mutation logic was reverted in
07278519bb6db5579171fea70bccdfee1306f1d4, we must bring the reader
method back as well, since the implementation relies on it.

We don't want the records to hold hard references to transactions
because they point at records that have callbacks.
|
| | |
|
| |
| |
| |
| |
| | |
this lets us keep singleton instances of "state" values and precalculate
return values of things like `finalized?` and `completed?`.
|
| |
| |
| |
| |
| | |
this way we don't have to mutate a state object, we can just change the
state of the txn

As far as I can tell nobody is setting this variable.
