* Transition complex objects to "too complex" shapeJemma Issroff2022-12-152-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an object becomes "too complex" (in other words it has too many variations in the shape tree), we transition it to use a "too complex" shape and use a hash for storing instance variables. Without this patch, there were rare cases where shape tree growth could "explode" and cause performance degradation on what would otherwise have been cached fast paths. This patch puts a limit on shape tree growth, and gracefully degrades in the rare case where there could be a factorial growth in the shape tree. For example: ```ruby class NG; end HUGE_NUMBER.times do NG.new.instance_variable_set(:"@unique_ivar_#{_1}", 1) end ``` We consider objects to be "too complex" when the object's class has more than SHAPE_MAX_VARIATIONS (currently 8) leaf nodes in the shape tree and the object introduces a new variation (a new leaf node) associated with that class. For example, new variations on instances of the following class would be considered "too complex" because those instances create more than 8 leaves in the shape tree: ```ruby class Foo; end 9.times { Foo.new.instance_variable_set(":@uniq_#{_1}", 1) } ``` However, the following class is *not* too complex because it only has one leaf in the shape tree: ```ruby class Foo def initialize @a = @b = @c = @d = @e = @f = @g = @h = @i = nil end end 9.times { Foo.new } `` This case is rare, so we don't expect this change to impact performance of most applications, but it needs to be handled.

* Add variation_count on classesJemma Issroff2022-12-151-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | Count how many "variations" each class creates. A "variation" is a a unique ordering of instance variables on a particular class. This can also be thought of as a branch in the shape tree. For example, the following Foo class will have 2 variations: ```ruby class Foo ; end Foo.new.instance_variable_set(:@a, 1) # case 1: creates one variation Foo.new.instance_variable_set(:@b, 1) # case 2: creates another variation foo = Foo.new foo.instance_variable_set(:@a, 1) # does not create a new variation foo.instance_variable_set(:@b, 1) # does not create a new variation (a continuation of the variation in case 1) ``` We will use this number to limit the amount of shapes that a class can create and fallback to using a hash iv lookup.

* ObjectSpace.dump_all: dump shapes as wellJean Boussier2022-12-083-13/+171
| | | | | | | | | | | | | | | | | | | | | | | | | I see several arguments in doing so. First they use a non trivial amount of memory, so for various memory profiling/mapping tools it is relevant to have visibility of the space occupied by shapes. Then, some pathological code can create a tons of shape, so it is valuable to have a way to have a way to observe shapes without having to compile Ruby with `SHAPE_DEBUG=1`. And additionally it's likely much faster to dump then this way than to use `RubyVM::Shape`. There are however a few open questions: - Shapes can't respect the `since:` argument. Not sure what to do when it is provided. Would probably make sense to not dump them. - Maybe it would make more sense to have a separate `ObjectSpace.dump_shapes`? - Maybe instead `dump_all` should take a `shapes: false` argument? Additionally, `ObjectSpace.dump_shapes` is added for the use case of debugging the evolution of the shape tree.
