[ruby/fiddle] Remove Vim commands

2024-06-20T06:16:57+00:00

(https://github.com/ruby/fiddle/pull/140)

Some of these commands just don't work (for example `sws` is not a Vim
setting). I think we should just remove these.

[ruby/fiddle] Mark Closure, Function and Handle as write barrier

2023-06-28T07:36:53+00:00

protected
(https://github.com/ruby/fiddle/pull/129)

They don't have a mark function, so they don't need any change.

[ruby/fiddle] Add `sym_defined?` methods to test if a symbol is defined (https://github.com/ruby/fiddle/pull/108)

2022-10-07T06:18:51+00:00

I would like to check if a symbol is defined before trying to access it.
Some symbols aren't available on all platforms, so instead of raising an
exception, I want to check if it's defined first.

Today we have to do:

```ruby
begin
  addr = Fiddle::Handle.sym("something")
  # do something
rescue Fiddle::DLError
end
```

I want to write this:

```ruby
if Fiddle::Handle.sym_defined?("something")
  addr = Fiddle::Handle.sym("something")
  # do something
end
```

[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] Remove taint support (#21)

2019-10-24T10:34:49+00:00

Ruby 2.7 deprecates taint and it no longer has an effect.
The lack of taint support should not cause a problem in
previous Ruby versions.
https://github.com/ruby/fiddle/commit/18d6fb6915

* ext/fiddle/handle.c: check tainted string arguments.

2015-12-16T12:08:49+00:00

  Patch provided by tenderlove and nobu.

* test/fiddle/test_handle.rb (class TestHandle): add test for above.

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@53153 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* ext/**/.c (_memsize): same as r52986 for extensions.
