Properly disable LUA_USE_DLOPEN for bootstrap flua

2020-08-14T02:40:17Z

flua does have some specific bits that will include luaconf.h, but the definition of LUA_USE_DLOPEN for those won't matter. This belongs in liblua instead. To expand on my previous commit, which was a little sparse with details, it's not really safe to allow LUA_USE_DLOPEN with host lib paths being used. The host system could have an entirely different lua version and this could cause us to crash and burn. If we want to revive this later, we need to make sure to define c module paths inside OBJDIR that are compiled against whatever version we've bootstrapped. Pointy hat: kevans

flua: don't allow dlopen, et al., for bootstrap flua

There are some logistics issues that need to be sorted out here before we can actually allow this to work.

flua: add ucl library

2020-06-22T03:14:43Z

libucl comes with a Lua library binding. Build it into flua. This lets us parse/generate config files in the various formats supported by libucl with flua. For example, the following script will detect the format of an object written to stdin as one of UCL config, JSON, or YAML and write it to stdout as pretty-printed JSON: local ucl = require('ucl') local parser = ucl.parser() parser:parse_string(io.read('*a')) local obj = parser:get_object() print(ucl.to_format(obj, 'json')) Reviewed by: kevans, pstef Approved by: mmacy (mentor) Relnotes: yes Differential Revision: https://reviews.freebsd.org/D25009

Add flua to the base system, install to /usr/libexec

FreeBSDlua ("flua") is a FreeBSD-private lua, flavored with whatever extensions we need for base system operations. We currently support a subset of lfs and lposix that are used in the rewrite of makesyscall.sh into lua, added in r354786. flua is intentionally written such that one can install standard lua and some set of lua modules from ports and achieve the same effect. linit_flua is a copy of linit.c from contrib/lua with lfs and lposix added in. This is similar to what we do in stand/. linit.c has been renamed to make it clear that this has flua-specific bits. luaconf has been slightly obfuscated to make extensions more difficult. Part of the problem is that flua is already hard enough to use as a bootstrap tool because it's not in PATH- attempting to do extension loading would require a special bootstrap version of flua with paths changed to protect the innocent. src.lua.mk has been added to make it easy for in-tree stuff to find flua, whether it's bootstrap-flua or relying on PATH frobbing by Makefile.inc1.
