Inside ObjectSpace.reachable_objects_from we keep an internal identhash
in order to de-duplicate reachable objects when wrapping them as
InternalObject. Previously this hash was not hidden, making it possible
to leak references to those internal objects to Ruby if using
ObjectSpace.each_object.
This commit solves this by hiding the hash. To simplify collection of
values, we instead now just use the hash as a set of visited objects,
and collect an Array (not hidden) of values to be returned.

Add a new macro BASE_SLOT_SIZE that determines the slot size.
For Variable Width Allocation (compiled with USE_RVARGC=1), all slot
sizes are powers-of-2 multiples of BASE_SLOT_SIZE.
For USE_RVARGC=0, BASE_SLOT_SIZE is set to sizeof(RVALUE).

This commit adds support for embedded strings with variable capacity and
uses Variable Width Allocation to allocate strings.

When `require "objspace/trace"` fails, previously the failure says:
```
1) Failure:
TestObjSpace#test_objspace_trace [/tmp/ruby/v3/src/trunk-mjit/test/objspace/test_objspace.rb:621]:
<3> expected but was
<0>.
```
but this is hard to debug.

This file, when require'ed, starts tracing the object allocations, and
redefines `Kernel#p` to show the allocation site.
This commit is experimental; the library name and APIs may change.

`memsize_of(Object.new)` can be changed with past ivar creation
history for Object instances (another Object instance has 4 or
more ivars, next created Object instance has the area for the
ivars). So use antoher class for the comparison.
|
|
test_memsize_of_iseq fails on repeat tests and it seems to difficult
to solve immediately. Now this test is skipped.
It seems that the result of `memsize_of(Object.new)` are increased.
Why...?

RUBY_INTERNAL_EVENT_NEWOBJ can expose uninitialized imemo_env
objects and marking it will cause critical error. This patch
skips marking on uninitialized imemo_env.
See: http://rubyci.s3.amazonaws.com/centos7/ruby-master/log/20210329T183003Z.fail.html.gz
Shortest repro-code is provided by mame-san.

RDoc says `ObjectSpace.dump(obj, output: :stdout) # => nil`,
but it returns STDOUT since fbba6bd4e3dff7a61965208fecae908f10c4edbe.
I think it is unintentional change.

The added test case crashes the interpreter because it makes
ObjectSpace.internal_class_of return the second VALUE slot of an AST
imemo object. The second VALUE slot of `struct rb_ast_struct` is
not a VALUE and not a pointer to a Ruby object.

The two main optimization are:
- buffer writes for improved performance
- avoid formatting functions when possible

This is useful to see what a block of code allocated, e.g.
```
GC.start
GC.disable
ObjectSpace.trace_object_allocations do
# run some code
end
gc_gen = GC.count
allocations = ObjectSpace.dump_all(output: :file, since: gc_gen)
GC.enable
GC.start
retentions = ObjectSpace.dump_all(output: :file, since: gc_gen)
```

Compaction makes collisions in the weak map more likely. For now, clear
the tracing information before the test run so we get accurate results
|
|
The allocation tracing code keeps essentially a weak reference to
objects that have been allocated (storing the allocation information
along with the weak ref). Compacting the heap would break references in
this weak map, so the wrong values could be returned.
This commit just updates the values in the weak ref in order to fix the
allocation tracing book keeping

It's possible to define methods with any name, even if the parser
doesn't support it and it can only be used with ex. send.
This fixes an issue where invalid JSON was output from ObjectSpace.dump
when a method name needed escaping.

* ext/objspace/objspace.c (count_imemo_objects): `imemo_type_ids`

patch fix mismatch.

The format addresses are printed in are different if you use
`ObjectSpace.dump_all(output: :stdout)` vs.
`ObjectSpace.dump_all(output: :string)` (or `ObjectSpace.dump`) due to
differences in the underlying `vfprintf` implementation.
Use `"%#"PRIxVALUE` to format `VALUE`.

This reverts commit r64970.
Visual C++ 12.0 doesn't have PRIxPTR.
Anyway we have our own vfprintf implementation BSD_vfprintf().
If you want to have portable vfprintf, replace it with BSD_vfprintf like
vsnprintf or just use BSD_vfprintf.

Use %"PRIxPTR" instead to be consistent across both.

IMEMO objects have many types. Without this change, we cannot see what
types of IMEMO objects are being used when dumping the heap. Adding the
type to the IMEMO object will allow us to gather statistics about IMEMO
objects being used.

The `full` option includes all slots (even `T_NONE`) in the JSON output.
This is to help with debugging heap fragmentation.
Here is an example usage:
```ruby
File.open('heap.json', 'w') do |f|
ObjectSpace.dump_all(output: f, full: true)
end
```
The `heap.json` file contains all slots, including empty slots.

This commit changes full heap dumps back to using JSON lines format
(http://jsonlines.org) so that we can process very large heaps without
loading the entire heap in to memory at once.
