This reverts commit adbc9ccc9b.

Alex Orlenko 8ff610529b Don't wrap ExtraData to Arc<Mutex> and use raw pointer instead.
This causes serious performance issues and given that Lua is
single threaded (not Sync) it's safe to use a raw pointer instead.

Alex Orlenko 1fe583027b Add new functions: lua.load_from_function() and lua.create_c_function()
This should be useful to register embedded C modules to Lua state.
Provides a solution for #61

Alex Orlenko 41aae83304 Optimize callback creation
Attach only one upvalue to callbacks rather than two.
This leads to less lookup to Lua registry.

Alex Orlenko 14d5c2c887 Lua->Rust callback performance improvements 2021-06-20 00:24:53 +01:00
Alex Orlenko 4e92ea341b Fix userdata memleak in edge case.
This can happen if we unable to push metatable with `__gc` metamethod after pushing userdata.
In this case Lua will never execute drop.
Instead, we will push metatable first and then userdata.

Alex Orlenko d3f44354e0 Revert commit ced808d5ab
I think this experiment is unsuccessful and does not work well in a module mode
with dynamic symbols resolution and mixing between different mlua instances.
Overall the Rust bug has been fixed and we can wait for the "C-unwind" feature become stable.

Alex Orlenko 08ffeb0ca9 Improve module mode:
- Don't hide module function inside `luaopen_%` function.
- Raise Lua exception instead of panic if module function returns error.

Alex Orlenko e8de2a458a Allow multiple entrypoints in a single module share the same Lua state.
Previously it would initialize different Lua instances.
Fixes #49.

Alex Orlenko 41a1a0d15a Add more checks for destructed userdata in AnyUserData 2021-04-27 00:29:38 +01:00
Alex Orlenko ced808d5ab Don't trigger longjmp in rust.
Motivation behind this change is upcoming breaking change in Rust
compiler v1.52.0 to prevent unwinding across FFI boundaries.
https://github.com/rust-lang/rust/pull/76570
The new functionality requires nightly compiler to declare FFI
functions as "C-unwind".
The fundamental solution is to use C shim to wrap "e" and "m"
Lua functions in pcall.
Additionally define Rust calling convention to trigger lua_error
on Rust behalf.

Alex Orlenko 0c7db4916c Serialize only known (registered) userdata.
This reverts commit 7332c6a.
Non-static userdata is a special case and can cause segfault if try to serialize it.
Now it should be safe, plus I added non-static userdata destructor to generate better error messages
in case of accessing destructed userdata.
