* | Apply scale before precision when coercing floats to decimalSean Griffin2016-03-241-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since precision is always larger than scale, it can actually change rounding behavior. Given a precision of 5 and a scale of 3, when you apply the precision of 5 to `1.25047`, the result is `1.2505`, which when the scale is applied would be `1.251` instead of the expected `1.250`. This issue appears to only occur with floats, as scale doesn't apply to other numeric types, and the bigdecimal constructor actually ignores precision entirely when working with strings. There's no way we could handle this for the "unknown object which responds to `to_d`" case, as we can't assume an interface for applying the scale. Fixes #24235

* Revert changes to validations from PR #18612eileencodes2016-02-231-11/+0
| | | | | | | | | | | | | | | | | | | | In order to fix issue #17621 we added a check to validations that determined if a record should be validated. Based on the existing tests and behavior we wanted we determined the best way to do that was by checking if `!record.peristed? || record.changed? || record.marked_for_destruction?` This change didn't make it into a release until now. When #23790 was opened we realized that `valid?` and `invalid?` were broken and did not work on persisted records because of the `!record.persisted?`. While there is still a bug that #17621 brought up, this change was too drastic and should not be a RC blocker. I will work on fixing this so that we don't break `valid?` but also aren't validating parent records through child records if that parent record is validate false. This change removes the code changes to validate and the corresponding tests. It adds tests for two of the bugs found since Rails 5 beta2 release. Fixes #17621

* | Always validate record if validating a virtual attributeeileencodes2016-02-201-0/+7
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes #23645 When you're using an `attr_accessor` for a record instead of an attribute in the database there's no way for the record to know if it has `changed?` unless you tell it `attribute_will_change!("attribute")`. The change made in 27aa4dd updated validations to check if a record was `changed?` or `marked_for_destruction?` or not `persisted?`. It did not take into account virtual attributes that do not affect the model's dirty status. The only way to fix this is to always validate the record if the attribute does not belong to the set of attributes the record expects (in `record.attributes`) because virtual attributes will not be in that hash. I think we should consider deprecating this particular behavior in the future and requiring that the user mark the record dirty by noting that the virtual attribute will change. Unfortunately this isn't easy because we have no way of knowing that you did the "right thing" in your application by marking it dirty and will get the deprecation warning even if you are doing the correct thing. For now this restores expected behavior when using a virtual attribute by always validating the record, as well as adds tests for this case. I was going to add the `!record.attributes.include?(attribute)` to the `should_validate?` method but `uniqueness` cannot validate a virtual attribute with nothing to hold on to the attribute. Because of this `should_validate?` was about to become a very messy method so I decided to split them up so we can handle it specifically for each case.

* | Refactor tz aware types, add support for PG rangesSean Griffin2016-01-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an alternate implementation to #22875, that generalizes a lot of the logic that type decorators are going to need, in order to have them work with arrays, ranges, etc. The types have the ability to map over a value, with the default implementation being to just yield that given value. Array and Range give more appropriate definitions. This does not automatically make ranges time zone aware, as they need to be added to the `time_zone_aware` types config, but we could certainly make that change if we feel it is appropriate. I do think this would be a breaking change however, and should at least have a deprecation cycle. Closes #22875. /cc @matthewd

|/ | | | | | | | | | | | A regression (#22744) introduced in 7500dae caused certain numericality validations to raise an error when run against an attribute with a string value. Previously, these validations would successfully run against string values because the value was cast to a numeric class. This commit resolves the regression by converting string values to floats before performing numericality comparison validations. [fixes #22744]

* Use a bind param for `LIMIT` and `OFFSET`Sean Griffin2015-12-141-0/+5
| | | | | | | | | | | | | | | We currently generate an unbounded number of prepared statements when `limit` or `offset` are called with a dynamic argument. This changes `LIMIT` and `OFFSET` to use bind params, eliminating the problem. `Type::Value#hash` needed to be implemented, as it turns out we busted the query cache if the type object used wasn't exactly the same object. This drops support for passing an `Arel::Nodes::SqlLiteral` to `limit`. Doing this relied on AR internals, and was never officially supported usage. Fixes #22250.

| * Conditionally convert the raw_value received by the numeric validator.Roque Pinel2015-07-111-12/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the issue where you may be comparing (using a numeric validator such as `greater_than`) numbers of a specific Numeric type such as `BigDecimal`. Previous behavior took the numeric value to be validated and unconditionally converted to Float. For example, due to floating point precision, this can cause issues when comparing a Float to a BigDecimal. Consider the following: ``` validates :sub_total, numericality: { greater_than: BigDecimal('97.18') } ``` If the `:sub_total` value BigDecimal.new('97.18') was validated against the above, the following would be valid since `:sub_total` is converted to a Float regardless of its original type. The result therefore becomes Kernel.Float(97.18) > BigDecimal.new('97.18') The above illustrated behavior is corrected with this patch by conditionally converting the value to validate to float. Use the post-type-cast version of the attribute to validate numericality [Roque Pinel & Trevor Wistaff]
* | All strings returned by `ImmutableString` should be frozenSean Griffin2015-10-152-11/+7
| | | | | | | | | | | | | | I seriously don't even know why we handle booleans, but those strings should technically be frozen. Additionally, we don't need to actually check the class in the mutable string type, since the `cast_value` function will always return a string.
* | Add an immutable string type to opt out of string dupingSean Griffin2015-10-153-20/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This type adds an escape hatch to apps for which string duping causes unacceptable memory growth. The reason we are duping them is in order to detect mutation, which was a feature added to 4.2 in #15674. The string type was modified to support this behavior in #15788. Memory growth is really only a concern for string types, as it's the only mutable type where the act of coersion does not create a new object regardless (as we're usually returning an object of a different class). I do feel strongly that if we are going to support detecting mutation, we should do it universally for any type which is mutable. While it is less common and ideomatic to mutate strings than arrays or hashes, there shouldn't be rules or gotchas to understanding our behavior. However, I also appreciate that for apps which are using a lot of string columns, this would increase the number of allocations by a large factor. To ensure that we keep our contract, if you'd like to opt out of mutation detection on strings, you'll also be option out of mutation of those strings. I'm not completely married to the thought that strings coming out of this actually need to be frozen -- and I think the name is correct either way, as the purpose of this is to provide a string type which does not detect mutation. In the new implementation, I'm only overriding `cast_value`. I did not port over the duping in `serialize`. I cannot think of a reason we'd need to dup the string there, and the tests pass without it. Unfortunately that line was introduced at a time where I was not nearly as good about writing my commit messages, so I have no context as to why I added it. Thanks past Sean. You are a jerk.

* | `validates_acceptance_of` shouldn't require a database connectionSean Griffin2015-09-251-4/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | The implementation of `attribute_method?` on Active Record requires establishing a database connection and querying the schema. As a general rule, we don't want to require database connections for any class macro, as the class should be able to be loaded without a database (e.g. for things like compiling assets). Instead of eagerly defining these methods, we do it lazily the first time they are accessed via `method_missing`. This should not cause any performance hits, as it will only hit `method_missing` once for the entire class.
* | Improve the performance of `save` and friendsSean Griffin2015-09-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The biggest source of the performance regression in these methods occurred because dirty tracking required eagerly materializing and type casting the assigned values. In the previous commits, I've changed dirty tracking to perform the comparisons lazily. However, all of this is moot when calling `save`, since `changes_applied` will be called, which just ends up eagerly materializing everything, anyway. With the new mutation tracker, it's easy to just compare the previous two hashes in the same lazy fashion. We will not have aliasing issues with this setup, which is proven by the fact that we're able to detect nested mutation. Before: User.create! 2.007k (± 7.1%) i/s - 10.098k After: User.create! 2.557k (± 3.5%) i/s - 12.789k Fixes #19859
* | Clean up the implementation of AR::DirtySean Griffin2015-09-242-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | This moves a bit more of the logic required for dirty checking into the attribute objects. I had hoped to remove the `with_value_from_database` stuff, but unfortunately just calling `dup` on the attribute objects isn't enough, since the values might contain deeply nested data structures. I think this can be cleaned up further. This makes most dirty checking become lazy, and reduces the number of object allocations and amount of CPU time when assigning a value. This opens the door (but doesn't quite finish) to improving the performance of writes to a place comparable to 4.1

| | | | | | | | | | | | | | In Active Record, it appears these were either autoloaded, which actually was likely due to test ordering since the method `Float#to_d` wouldn't trigger it. This makes it explicit, and unlikely to fail in the future.

* | Move the appropriate type tests to the Active Model suiteSean Griffin2015-09-211-2/+8
| | | | | | | | | | | | | | | | | | Any tests for a type which is not overridden by Active Record, and does not test the specifics of the attributes API interacting in more complex ways have no reason to be in the Active Record suite. Doing this revealed that the implementation of the date and time types in AM was actually completely broken, and incapable of returning any value other than `nil`.
* | Simplify the implementation of Active Model's type registrySean Griffin2015-09-211-97/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Things like decorations, overrides, and priorities only matter for Active Record, so the Active Model registry can be implemented much more simply. At this point, I wonder if having Active Record's registry inherit from Active Model's is even worth the trouble? The Active Model class was also missing test cases, which have been backfilled. This removes the error when two types are registered with the same name, but given that Active Model is meant to be significantly more generic, I do not think this is an issue for now. If we want, we can raise an error at the point that someone tries to register it.

| | | | | | | | | | | | | | We do not need to require each file from AM individually, the type module does that for us. Even if the classes are extremely small right now, I'd rather keep any custom classes needed by AR in their own files, as they can easily have more complex changes in the future.
