这是LuaJIT官方所推荐的,原文如下: For new designsavoid push-style APIs: a C function repeatedly calling a callback for each result. Insteaduse pull-style APIs: call a C function repeatedly to get a new result. Calls from Lua to C via the FFI are much faster than the other way round. ...

FFI 库允许从纯 Lua 代码调用外部 C 函数和使用 C 数据结构。 jit.*— JIT 编译器控制 此模块中的函数控制 JIT 编译器引擎的行为。 C API 扩展 LuaJIT为 Lua/C API 添加了一些额外的功能。 增强的标准库函数 xpcall(f, err [,args...])传递参数 ...
You really want to call jit.off(func) (once!) and pass the Lua function that calls a C function which may invoke a callback. Also, don't create and destroy the same callback on every call. And don't keep allocating structs that can be recycled. Untested solution: local mmba = ffi...

The FFI feature may be added and may be useful, but we should not expect or force mods to use it as a way around the memory issue, it should be an optional thing that is not essential. We should not let this issue force us into a false resolution of relying on FFI. ...

lua-resty-openssl is a FFI-based OpenSSL binding library, currently supports OpenSSL 3.0.0, 1.1.1, 1.1.0 and 1.0.2 series.Note: when using with OpenSSL 1.0.2, it's recommanded to not use this library with other FFI-based OpenSSL binding libraries to avoid potential mismatch of cdef....
