Bug#964073: lintian: Possible false positives for breakout-link for Lua modules

[Sergei Golovan <sgolovan@nes.ru>]

Package: lintian
Version: 2.82.0
Severity: normal

Dear Maintainer,

Recently, lintian started to emit the breakout-link warning for a bunch of Lua
related packages. A typical structure of a Lua package with a C library is the
following:

The C library with a symlink (to allow someone to link a program in C to it):

/usr/lib/x86_64-linux-gnu/liblua5.1-sec.so.1.0.0
/usr/lib/x86_64-linux-gnu/liblua5.1-sec.so.1 -> liblua5.1-sec.so.1.0.0

The symlink which lets Lua find the library (by require "ssl")

/usr/lib/x86_64-linux-gnu/lua/5.1/ssl.so -> ../../liblua5.1-sec.so.1.0.0

Since it points to a higher location in the file system, lintian shows a
warning. Though, the link never goes outside /usr/lib/x86_64-linux-gnu,
so I would say that this warning is spurious.

Can it be fixed in Lintian?

I can think of another way of fixing it by reverting the linkage (make
/usr/lib/x86_64-linux-gnu/lua/5.3/ssl.so a real file and point the symlink
/usr/lib/x86_64-linux-gnu/liblua5.1-sec.so.1.0.0 to it), but I'm not sure
it's worth the effort.

Cheers!
