I noticed you didn't expose lua_loadbuffer as an external symbol in

Lua 4.0 officially has no lua_loadbuffer and friends.
*Please*, package the official Lua 4.0 code. You may want to add the patch
as a separate thing, of course. Thanks.

Hmm, I can either package it in the "Debian version" of lua 4.0 or else I
could provide an "alternative" liblua package.

My current favourite is to make the symbol exposed but guard the definition
of it in lua.h with something like


How does that sit with people?

The only other thought I have is to NOT change their names, but just remove the static flag. That way, is not exporting anything new in the public lua_foo namespace.

The alias lua_loadbuffer could then be applied either through a #define or a function exported in another library. Or maybe better yet, we throw it in the Debian namespace like dllua_loadbuffer.

In any case, the goal is to make sure developers using this function understand that it is not a standard function. If Debian users were building from source, we could just tell them to apply a patch to the pristine sources, but they use binaries, and there are significant benefits to maintainers, developers, and end-users in not shipping two conflicting versions of a shared library when the differences are so small.

(BTW, Debian regularly ships heavily patched versions of other interpreters. tk8.0 through tk8.2 ship not only with a full set of internals include files, but also with the "plus" patch applied, which exports significant user-visible functionality.)
