Bug#521308: lintian: new warning: build-depends-indep, but no build-indep

[Lionel Elie Mamane <lionel@mamane.lu>]

Package: lintian
Version: 2.2.8
Severity: wishlist

I just ran into the case of a package that had a Build-Depends-Indep
line, but where binary-indep depended on "build" and not build-indep
(because there was no build-indep), and so did binary-arch. This looks
like it usually won't work: the building for indep does not do any
more (or different) work than the building for arch, so there is no
dependency that would be necessary for indep, but not for arch. Yes,
one can imagine these things being used in binary-indep itself (and
not in binary-arch), but that looks improbable.


I thus propose the following new lintian checks:

 - ERROR if binary-indep and binary-arch depend (directly or
         indirectly) on only the same work-doing (containing
	 commands) targets AND Build-Depends-Indep not empty.

   For example:

   binary-arch: install
      (some commands here)
   binary-indep: install
      (some commands here)

   or

   binary-arch: build-arch
      (some commands here)
   binary-indep: build-indep
      (some commands here)
   build-arch: build
   build-indep: build
   build:
      (some commands here)

 - ERROR if build-arch and build-indep exist, but build-indep doesn't
         do any work itself and just depends on the same targets as
	 build-arch (or on build-arch) AND Build-Depends-Indep not
	 empty

 - WARNING if binary-indep depends (directly or indirectly) on
           install, install-stamp, build, build-stamp
