Object specialization #419

HalidOdat · 2020-05-25T21:05:26Z

It changes the following:

Specializes objects
Implements Hash trait for Value
Implements PartialEq trait based on the SameValueZero algorithm for Value (required by Hash trait)
Implements Eq trait for Value (required by Hash trait)
Fixed a bug when comparing object pointers in same_value_non_number
Deprecated ObjectInternalMethods
Fixed Symbol primitive
Added construct_type_error and construct_range_error
Made Number objects constructor and methods more specification compliant.
Abstracted Object name and function object length.
Changed init functions to return (&str, Value)

The problem with the current implementation is that we store the data in an internal slot. The internal slots are stored as a HashMap, which means slow reads and writes. Additionally they are stored as a Value which means we need additional checks to unwrap the Value into a primitive (example f64, String) to access the data. Furthermore we are restricted as to what type of data we can hold, for example if we wanted to implement Set object with native type HashSet, we can not do so in the internal slots as they are specified in the standard (it's only an implementation detail).
This PR aims to allow use of non-Value types in objects as well as removing the need for internals slots for data storage (NumberData, StringData, etc), removing redundant checks for data access. It should increase performance greatly for object access and a bit for object creation. (I'm not sure the benchmarks will show it though, since we do not have benchmarks for objects).

I'm not very used to deal with the Gc, but this seems to be that two calls to borrow() were made one after the other without a clone() or a scope ending in the middle.

I did some benchmarks on Object creation and access

I think the other execution benchmarks are wrong, we use exec function to benchmark execution, but exec does not just execute the string, it lexes, parsers, creates the interpreter and initializes/creates the realm and then it executes the code, aren't we polluting the result of the benchmark? Shouldn't we isolate what were executing as much as possible, right?
With exec function, I saw a ~4%, when I isolated the execution I saw a ~20% increase for object creation/access.

You can check the benchmark here

What do you think @Razican and @jasonwilliams ?

@jasonwilliams noticed that most of the execution time is spent on Realm creation, so I think we should isolate the actual execution, yes, in order to see if we improve or worsen there.

OK, an extra bunch of comments. I think one of the best things we could do is using an Object directly instead of a Value as the global object when initializing the Realm.

We still don't have benchmarks for the specialized objects 😅 , Like Number object not primitive, the benchmarks for string don't test String object only string primitives. although the speed boost is really nice :)

Edit: Made some benchmarks for some specialized objects #494

This is good to go from my side. We might want to wait for the extra benchmarks though, to have some extra info.

- Added helper functions for Object and ValueData - Added `Hash` trait to `Value` - Abstracted Object field access - Deprecated `ObjectInternalMethods` - Optimized Realm creation - Fixed `Symbol` primitive

hash The problem with using the pointer as the hash, it can become a security vulnerability.

This type change removes 8-bytes from Symbol type size.

- Added `#[inline]` to some small functions
