Make the SHAPE_TOO_COMPLEX performance warning more actionable

2023-12-18T09:33:18+00:00

As suggested by Mame, we should try to help users fix the issues
without having to lookup the meaning of the warning.

Re-embed when removing Object instance variables

2023-12-06T16:34:07+00:00

Objects with the same shape must always have the same "embeddedness"
(either embedded or heap allocated) because YJIT assumes so. However,
using remove_instance_variable, it's possible that some objects are
embedded and some are heap allocated because it does not re-embed heap
allocated objects.

This commit changes remove_instance_variable to re-embed Object
instance variables when it becomes small enough.

Make the maximum shapes variation warning non-verbose

2023-05-03T08:43:46+00:00

[Feature #19538]

Since that category is not enabled by default, making it a
verbose warning is redundant. Enabling performance warning should
work with the default verbosity level.

Emit a performance warning when a class reached max variations

2023-04-13T14:36:17+00:00

[Feature #19538]

This new `peformance` warning category is disabled by default.
It needs to be specifically enabled via `-W:performance` or `Warning[:performance] = true`

Use rb_inspect instead of +PRIsVALUE for Object.inspect

2022-12-09T13:11:00+00:00

In order to preserve the values when TrueClass, FalseClass or NilClass
are stored in ivars

Freeze singleton class, not its origin

2022-12-08T20:58:26+00:00

Previously, when we froze an object, we froze
`RCLASS_ORIGIN(object.singleton_class)`, which didn't freeze
`object.singleton_class` when it has some prepended modules.

Origin iclass are internal objects and users can't interact with
them through Kernel#freeze?, Kernel#freeze, or any mutation method
that checks the frozen status. So we shouldn't touch the origin
iclasses when the frozen status should be visible.

Fix frozen object inspect

2022-09-30T20:57:59+00:00

In the rails/rails CI build for Ruby master we found that some tests
were failing due to inspect on a frozen object being incorrect.

An object's instance variable count was incorrect when frozen causing
the object's inspect to not splat out the object.

This fixes the issue and adds a test for inspecting frozen objects.
