Stop autoloading AbstractAdapter prematurely
In 7254d23764f7abe8023f3daeb07d99ea1c8e777a, an autoload for
`ConnectionAdapters::AbstractAdapter` was added to `active_record.rb`.
Later in d6b923adbdfc9a4df20132f741bbfb43db12113c, a manual require for
that class was added to `active_record/base.rb` as some constants under
`ConnectionAdapters` weren't defined until `AbstractAdapter` was loaded.
In 1efd88283ef68d912df215125951a87526768a51, the require was removed and
replaced with an autoload in `active_record.rb`, above the previous one.
Because the first autoload was for the `ConnectionAdapters` constant and
the second one tried to create it, the autoload would fire immediately.
Rather than fixing the autoload problem, the require had effectively
just been moved from `active_record/base.rb` to `active_record.rb`.
Instead of defining autoloads for constants under `ConnectionAdapters`
in the `abstract_adapter.rb` file, we can create a separate, autoloaded
`connection_adapters.rb` file for this purpose.
To avoid a "circular require considered harmful" warning from Ruby, we
have to fix the module nesting in `schema_creation.rb`, as a followup to
e4108fc619e0f1c28cdec6049d31f2db01d56dfd.
`AbstractAdapter` loads many other dependencies, so making it autoload
properly has a noticeable impact on the load time of `active_record.rb`.
Benchmark:
$ cat test.rb
require "bundler/setup"
before = ObjectSpace.each_object(Module).count
start = Process.clock_gettime(Process::CLOCK_MONOTONIC)
require "active_record"
finish = Process.clock_gettime(Process::CLOCK_MONOTONIC)
after = ObjectSpace.each_object(Module).count
puts "took #{finish - start} and created #{after - before} modules"
Before:
$ ruby test.rb
took 0.47532399999909103 and created 901 modules
After:
