[ruby/fiddle] Add constants for unsigned values (https://github.com/ruby/fiddle/pull/111)

2022-10-07T06:18:49+00:00

This commit adds constants for unsigned values. Currently we can use `-`
to mean "unsigned", but I think having a specific name makes Fiddle more
user friendly. This commit continues to support `-`, but introduces
negative constants with "unsigned" names

I think this will help to eliminate [this
code](https://github.com/ruby/ruby/blob/3a56bf0bcc66e14ffe5ec89efc32ecfceed180f4/lib/mjit/c_type.rb#L31-L38)

[ruby/fiddle] Use have_header and have_type to detect memory view availability

2021-07-13T10:37:46+00:00

Fix https://github.com/ruby/fiddle/pull/84

It may detect ruby/memory_view.h for system Ruby that is installed in
/usr.

We can use RUBY_API_VERSION_MAJOR to detect memory view availability
because memory view is available since Ruby 3.0.

[ruby/fiddle] Add a "pinning" reference (#44)

2020-11-18T00:05:13+00:00

* Add a "pinning" reference

A `Fiddle::Pinned` objects will prevent the objects they point to from
moving.  This is useful in the case where you need to pass a reference
to a C extension that keeps the address in a global and needs the
address to be stable.

For example:

```ruby
class Foo
  A = "hi" # this is an embedded string

  some_c_function A # A might move!
end
```

If `A` moves, then the underlying string buffer may also move.
`Fiddle::Pinned` will prevent the object from moving:

```ruby
class Foo
  A = "hi" # this is an embedded string

  A_pinner = Fiddle::Pinned.new(A) # :nodoc:

  some_c_function A # A can't move because of `Fiddle::Pinned`
end
```

This is a similar strategy to what Graal uses:

* rename global to match exception name

* Introduce generic Fiddle::Error and rearrange error classes

Fiddle::Error is the generic exception base class for Fiddle exceptions.
This commit introduces the class and rearranges Fiddle exceptions to
inherit from it.

[ruby/fiddle] Add support for specifying types by name as String or Symbol

2020-11-18T00:05:13+00:00

For example, :voidp equals to Fiddle::TYPE_VOID_P.

[ruby/fiddle] Add TYPE_CONST_STRING and SIZEOF_CONST_STRING for "const char *"

2020-11-18T00:05:13+00:00

Add rb_fiddle_ prefix to conversion functions.h to keep backward
compatibility but value_to_generic() isn't safe for TYPE_CONST_STRING
and not String src. Use rb_fiddle_value_to_generic() instead.
