I'm looking into upgrading this library to version 1 of libuv (1.0.2).
Looks like most things are working out of the box, but I'm struggling with scandir changes, specifically scandir_next.

Do you have plans to look at 1.0.2 yourself?
Do you have any tips on how to deal with scandir changes?

I'm getting this error on make test:

make test
luajit: src/uv/uv_tcp_t.lua:57: attempt to index upvalue 'libuv2' (a boolean value)
stack traceback:
    src/uv/uv_tcp_t.lua: in function 'listen'
    test/uv_test.lua:12: in function <test/uv_test.lua:9>
stack traceback:
    [builtin#19]: at 0x0100036e30

    test/uv_test.lua:9: in main chunk
    [C]: at 0x0100001f60
make: *** [run-tests] Error 1

I think it's related to this line in the Makefile:
gcc -dynamiclib src/uv/libuv2.c -o src/uv/lib/libuv2.dylib -luv -L src/uv/lib
where libuv2.dylib seems to be referencing /usr/local/lib/libuv.11.dylib instead of src/uv/lib/
I was not able to track it further. Thanks

There is no contact information for the maintainer, so I am posting here. Sorry.

This is awesome!

The project is still under active development, but is there any way I can help?

Great job at getting libuv to work with a synchronous syntax! However libuv changed a lot since 0.10.21 and building it against 0.11.27 yields a lot of errors. Do you mind taking a look by installing libuv with the --devel option: brew install --devel libuv before building luajit-libuv? Thanks

It seems the FFI approach with callbacks ends up hitting the callbacks limit wall (see http://luajit.org/ext_ffi_semantics.html#callback):

Callback resource handling
Callbacks take up resources — you can only have a limited number of them at the same time (500 - 1000, depending on the architecture). The associated Lua functions are anchored to prevent garbage collection, too.

A far-fetched example that demos the "too many callbacks" error:

for i=1, 1000 do
  uv.run(function()
    print(i)
  end)
end

Any workarounds?
