| * Add support for bidirectional destroy dependenciesSeb Jacobs2015-01-161-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this commit if you defined a bidirectional relationship between two models with destroy dependencies on both sides, a call to `destroy` would result in an infinite callback loop. Take the following relationship. class Content < ActiveRecord::Base has_one :content_position, dependent: :destroy end class ContentPosition < ActiveRecord::Base belongs_to :content, dependent: :destroy end Calling `Content#destroy` or `ContentPosition#destroy` would result in an infinite callback loop. This commit changes the behaviour of `ActiveRecord::Callbacks#destroy` so that it guards against subsequent callbacks. Thanks to @zetter for demonstrating the issue with failing tests[1].

This patch moves common option documentation to `add_column` and only documents the additional options in `column`.

(:nsec) This causes issues on any machine that runs an OS that supports nanoseconds timestamps, i.e. not-OS X, where the cache_key of the record persisted in the database (milliseconds precision) is out-of-sync with the cache_key in the ruby VM. This commit adds: A test that shows the issue, it can be found in the separate file `cache_key_test.rb`, because - model couldn't be defined inline - transactional testing needed to be turned off to get it to pass the MySQL tests This seemed cleaner than putting it in an existing testcase file. It adds :usec as a dateformat that calculates datetime in microseconds It sets precision of cache_key to :usec instead of :nsec, as no db supports nsec precision on timestamps

This leads to the cache populating extremely fast in some cases, with the statements never being reused. In particular, the two problematic cases are `where(foo: [1, 2, 3])` and `where("foo = ?", 1)`. In both cases we'll end up quoting the values rather than using a bind param, causing a cache entry for every value ever used in that query. It was noted that we can probably eventually change `where("foo = ?", 1)` to use a bind param, which would resolve that case. Additionally, on PG we can change our generated query to be `WHERE foo = ANY($1)`, and pass an array for the bind param. I hope to accomplish both in the future. For SQLite and MySQL, we still end up preparing the statements anyway, we just don't cache it. The statement will be cleaned up after it is executed. On postgres, we skip the prepare step entirely, as an API is provided to execute with bind params without preparing the statement. I'm not 100% happy on the way this ended up being structured. I was hoping to use a decorator on the visitor, rather than mixing a module into the object, but the way Arel has it's visitor pattern set up makes it very difficult to extend without inheritance. I'd like to remove the duplication from the various places that are extending it, but that'll require a larger restructuring of that initialization logic. I'm going to take another look at the structure of it soon. This changes the signature of one of the adapter's internals, and will require downstream changes from third party adapters. I'm not too worried about this, as worst case they can simply add the parameter and always ignore it, and just keep their previous behavior. Fixes #21992.
