| | | | | | | | | | | | | | | | | | | | | | | | The implementation from abstract/database_statements.rb seems to work just fine. And with ActiveRecord::Result now implementing an optimized #first method, the performance concerns previously addressed in https://github.com/rails/rails/commit/bf79aa4fc14aeb2646331e767038acf0b77e9e7f should not be an issue.

| | | | | | | | | | | | | | | When you only need the first element of a result set, you shouldn't need to instantiate all of hash_rows.

| | | | | | | | | | | | | | | | | | | | | | | | This method appears to have been partially used in connection pool caching, but it was introduced without much reasoning or any tests. One edge case test was added later on, but it was focused on implementation details. This method is no longer used outside of tests, and as such is removed.

This change will remove the catching a `RangeError`.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of refactoring mutation detection to be more performant, we introduced the concept of `original_value` to `Attribute`. This was not overridden in `Attribute::Uninitialized` however, so assigning ot an uninitialized value and calling `.changed?` would raise `NotImplementedError`. We are using a sentinel value rather than checking the result of `original_attribute.initialized?` in `changed?` because `original_value` might go through more than one node in the tree. Fixes #25228
* | | Fix failing testsSean Griffin2016-06-022-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently CI is broken due to 56a61e0 and c4cb686. This occurred because the failures are not present on SQLite which is what I normally run locally before pushing. The optimizations to our YAML size were dropping mutations, as `with_type` didn't set the previous value if it'd already been read (that method was never really designed to be used with values on individual objects, it was previously only used for defaults). I'm questioning whether there's a better place to be handling the exclusion of the type, but this will fix the failing build. Additionally, there was a bug in `remove_foreign_key` if you passed it an options hash containing `to_table`. This now occurs whenever removing a reference, as we always normalize to a hash.

* | | Make Active Record emit significantly smaller YAMLSean Griffin2016-05-317-7/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reduces the size of a YAML encoded Active Record object by ~80% depending on the number of columns. There were a number of wasteful things that occurred when we encoded the objects before that have resulted in numerous wins - We were emitting the result of `attributes_before_type_cast` as a hack to work around some laziness issues - The name of an attribute was emitted multiple times, since the attribute objects were in a hash keyed by the name. We now store them in an array instead, and reconstruct the hash using the name - The types were included for every attribute. This would use backrefs if multiple objects were encoded, but really we don't need to include it at all unless it differs from the type at the class level. (The only time that will occur is if the field is the result of a custom select clause) - `original_attribute:` was included over and over and over again since the ivar is almost always `nil`. We've added a custom implementation of `encode_with` on the attribute objects to ensure we don't write the key when the field is `nil`. This isn't without a cost though. Since we're no longer including the types, an object can find itself in an invalid state if the type changes on the class after serialization. This is the same as 4.1 and earlier, but I think it's worth noting. I was worried that I'd introduce some new state bugs as a result of doing this, so I've added an additional test that asserts mutation not being lost as the result of YAML round tripping. Fixes #25145
* | | Respect options passed to `foreign_key` when reverting `add_reference`Sean Griffin2016-05-311-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code incorrectly assumes that the option was written as `foreign_key: true`, but that is not always the case. This now mirrors the behavior of reverting `add_foreign_key`. The code was changed to use kwargs while I was touching it, as well. This could really use a refactoring to go through the same code paths as `add_refernce` in the future, so we don't duplicate default values. Fixes #25169

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This behavior was broken by 36e9be85. When the value is assigned directly, either through mass assignment or directly assigning a hash, the hash gets passed through to this writer method directly. While this is intended to handle certain cases, when an explicit converter has been provided, we should continue to use that instead. The positioning of the added guard caused the new behavior to override that case. Fixes #25210
