Each server need a separate lua virtual machine environment!

[fxg]

just about subject,for testing or development, a standalone lua VM ,is aways useful!

thanks for your great job!

What did you mean saying this? If you'll use LuaJIT2, then each nginx worker process will have separate lua VM. If you'll use Lua 5.1 instead, then you'll have no virtual machine at all.

@eoranged He means each (virtual) server block in nginx.conf owns its own Lua VM instance, that is, every nginx worker can have 3 Lua VM instances if the user defines three virtual servers in her nginx.conf.

@agentzh but when it could be useful? I see no profit creating separate Lua instances inside one process, especially with LuaJIT2.

It'll be useful when different applications share the same nginx
instance but each uses its own virtual server. And they surely want to
use separate versions of Lua modules and Lua module search paths
settings and etc.

Now I know a solution to this requirement: just define multiple http {} blocks for each server {} block and each virtual server will have its own isolated Lua VM and other configuration settings (in its surrounding http {} block).

I'm closing this :)
