Properly cache value when it is "false"

replaced some "i += 1" sort of codes with Enumerable#with_index

That integer is rather irrelevant, the only thing that matters is that
it is consistent and with no apparent bias. Zlib.crc32 is 8-10 times
faster than bytes.sum, so use that.

Fixing asset number for asset_path with %d to be consistent in ruby 1.9

Using the sum of bytes instead the hash of the path when replacing the wildcard of the assets path because in ruby 1.9 is not consistent

Rails app template: setup different mass assignment sanitizer for envs

Fix test warnings

For production - leave the default
For test and dev: :strict.

collection_singular_ids ignores association :include option

rake db:test:purge creates mysql database with wrong charset & collation (master branch)

Don't construct association scope in initializer. This yields a big performance gain for cases where the association is never used to load the target, for example with preloading. Related: #1873.

See new method mysql_creation_options. It is used by both
create_database and recreate_database so they are consistent.

(Cherry pick of 3ba3125b)

This is because only template rendering works with streaming.
Setting it at the class level was also changing the behavior
of JSON and XML responses, closes #1337.

Remove case statement changes from 2e0840dd and 56ac32ad. Inheritance FTW.

when condtions references tables from includes.
Test fail because of invalid sql:
ActiveRecord::StatementInvalid: SQLite3::SQLException: no such column: comments.id:
SELECT "posts".id FROM "posts" INNER JOIN "readers" ON "posts"."id" = "readers"."post_id"
WHERE "readers"."person_id" = 1 AND (comments.id is null)
