07:07 AM Ruby Revision 95c041bd (git): [ruby/json] generator.c: Handle stupidly large depth

06:25 AM Ruby Revision fb369617 (git): [ruby/json] Add missing write barrier in ParserConfig

This couldn't possibly lead to a crash unless you'd mess
with GC.stress or `send(:initialize)` on an old object.
But for correctness, it should be there.

04:05 PM Ruby Feature #22056: Add zero-copy String constructor backed by an arbitrary Ruby object

Another though: what does it means for coderanges? Since the buffer is owned by another object, it can be mutated without going through one of String methods, which means things like `ENC_CODERANGE_CLEAR` won't happen.
Perhaps it's ac... byroot (Jean Boussier)

04:01 PM Ruby Feature #22056: Add zero-copy String constructor backed by an arbitrary Ruby object

> by leveraging the existing STR_NOFREE mechanism.
I see. So it's mutable, but Copy-on-Write. If you mutate the string, all the content is copied in a buffer managed by Ruby. byroot (Jean Boussier)

02:13 PM Ruby Feature #22056: Add zero-copy String constructor backed by an arbitrary Ruby object

Somewhat related proposal: [Feature #20878]
I also wonder, this new "external" string is supposed to be mutable? If so that may increase `string.c` complexity significantly, as all codepaths that normally resize the string buffer will... byroot (Jean Boussier)

08:10 AM Ruby Revision 4eeec614 (git): shapes: Rename `TOO_COMPLEX` in just `COMPLEX`

The `too_` prefix wasn't consistently used and just make the
thing longer for no benefit. byroot (Jean Boussier)

08:10 AM Ruby Revision deceb9f6 (git): Rename `rb_shape_obj_*` into `rb_obj_shape_*`

For consistency. byroot (Jean Boussier)

07:02 AM Ruby Revision 678d86f5 (git): shape.c: transition to complex when `max_capacity` is reached

Now that we have 1024B slots, we can store up to 126 fields inline.
Objects larger than this are rare if not non-existent, hence we can
get rid of the `malloc` path for imemo/fields and simply transition
to `TOO_COMPLEX`.
This addition... byroot (Jean Boussier)
