When a Ractor is created whilst a tracepoint for
RUBY_INTERNAL_EVENT_NEWOBJ is active, the interpreter crashes. This is
because during the early setup of the Ractor, the stdio objects are
created, which allocates Ruby objects, which fires the tracepoint.
However, the tracepoint machinery tries to dereference the control frame
(ec->cfp->pc), which isn't set up yet and so crashes with a null pointer
dereference.
Fix this by not firing GC tracepoints if cfp isn't yet set up.
When we use this methods with local gemspec, we don't handle
build status of extension correctly. So We need to find extension
files in require_paths.
Example with ruby/erb repository:
```
$ bundle exec irb
Ignoring erb-4.0.2 because its extensions are not built. Try: gem pristine erb --version 4.0.2
>>
```

This works much like the existing `defined` implementation,
but calls out to rb_ivar_defined instead of the more general
rb_vm_defined.
Other difference to the existing `defined` implementation is
that this new instruction has to take the same operands as
the CRuby `defined_ivar` instruction.
This is a variation of the `defined` instruction, for use when we
are checking for an instance variable. Splitting this out as a
separate instruction lets us skip some checks, and it also allows
us to use an instance variable cache, letting shape analysis
speed up the operation further.
We need to zero out the whole slot when running the newobj hook for a
newly allocated class because the slot could be filled with garbage,
which would cause a crash if a GC runs inside of the newobj hook.
For example, the following script crashes:
```
require "objspace"
GC.stress = true
ObjectSpace.trace_object_allocations {
100.times do
Class.new
end
}
```
[Bug #19482]
libcapstone used to break when it's linked from C and Rust at the same
time, but it doesn't seem to happen anymore. Maybe it's related to
recent symbol hygiene changes. Thank you if that's the case.
This commit allows you to make both --enable-rjit=dev and
--enable-yjit=dev work in the same binary.
We used to require MJIT is supported when YJIT is supported. However,
now that RJIT dropped some platforms that YJIT supports, it no longer
makes sense. We should be able to enable only YJIT, and vice versa.
Currently, the --no-install option to `bundle package` is totally
ignored for git sources. This can have very strange effects if you have:
- a git-sourced gem,
- with native extensions,
- whose extconf.rb script depends on another gem,
- which is installed from Rubygems in the gemfile.
In that circumstance, `bundle package --no-install --all` will download
the Rubygems dependencies to `vendor/cache` but NOT install them. It
will also check out the git gems to `vendor/cache` (good), and attempt
to build their native extensions (bad!).
The native extension build will fail because the extconf.rb script crashes,
since the dependency it needs is missing.
I implemented a fix for this in `source/git.rb`, since this is analogous
to what's happening in `source/rubygems.rb`. I do admit though the whole
thing is a little strange though - an "install" method that.... proceeds
to look at a global flag to not install anything.
Add test to confirm cache respects the --no-install flag
