I had a rather amateurish go at Mr. Abeille's generous offer to DoS his server using the method he described (colliding HTTP headers), and tcpserver+Nanoki seemed to serve it well. 36k colliding head

Bah... In the meantime, feel free to break Nanoki, which sports an HTTP server implemented in pure Lua. The HTTP implementation doesn't impose any limit of any kind and will happily attempt to proces

I got the enum patch working, that's good news. The bad news is, it's actually slower than my userdata-based approach (outside of lua core) used to be.. So. I'd very much like someone to read the cod

I think this issue only applies to long string keys, right? one reason long strings are special is that long string is the only type in Lua of which different objects might be regarded as being equa

Also if any lua support guys are listening I was wondering if it might be better to just add this to the library at some point. The way I hacked it before the library worked exactly the way it used

Hi folks, the whole binding issue (tolua vs SWIG etc) went through my mind recently, and I came up with this atrocity for Lua-5.0 and Linux. It is of course seriously non-portable, but similar hacks

I really wasn't going to get into this but I ended up thinking about it whilst walking to work this morning. I also think that \n\r is not a real line ending. If that's the case, you could use the so

Generators using coroutines is not the best way to implement them; it is simpler to use a first function that returns the generator function inside the closure of the first function that contains the
