LuaJit 2.1 is requirement or recomendation

iscander

Hello,
I've just checked lua-resty-core prerequisites here
https://github.com/agentzh/lua-resty-core#prerequisites I found LuaJit
2.1 there. Is it required ot OpenResty works with LuaJit 2.0.3 too?
I'm trying to rebuild OpenResty on stable releases LuaJit 2.0.3, NGiNX
1.4.7 - will it works?

Thank you in advance

OpenResty should work with LuaJIT 2.0.x. lua-resty-core is just for
optimizations, and there is little benefit in using lua-resty-core
with LuaJIT 2.0.x (due to its very limited JIT compiler).

LuaJIT 2.1 is highly recommended.

It should. But I no longer run my tests against LuaJIT 2.0.x. If you
find incompatibilities, let me know.

info

Is this a openresty thing or is this also valid for most individual modules like nginx for Windows uses? I'd like to stick to 2.0.3 since 2.1 is too much into a development state.

It also applies to ngx_lua for Windows. OpenResty is just a bundle anyway.

Just to be clear:

1. we always run the latest LuaJIT v2.1 in our global network at CloudFlare.

2.  All the recent performance improvements we (CloudFlare) has
sponsored only land in v2.1.

3. For one of our typical Lua apps at the level of 10K+ LOC, LuaJIT
v2.1 gives over 100% over-all speedup as compared to LuaJIT 2.0.x
(when lua-resty-core is used).

4. Many important bug fixes in the v2.1 branch have been back ported
to 2.0.x series because these bugs were also in 2.0.x (just hidden for
long). The latest 2.0.3 release is such a proof.

That's why LuaJIT v2.1 is strongly recommended if one really needs speed.
