Bug#385178: Bad dependencies managment that produce wrong lintian errors

[Vincent Danjean <Vincent.Danjean@ens-lyon.org>]

Package: lintian
Version: 1.23.23
Severity: normal
Tags: patch

  Hi,
 
  I just see that my package (tailor) trigger a lintian error:
vdanjean@cayuga:~/debian/mainteneur/tailor$ lintian -i tailor_0.9.26-1_all.deb
E: tailor: python-script-but-no-python-dep ./usr/bin/tailor
N:
N:   Packages with scripts that are executed with python must depend on the
N:   package python. Those that have scripts executed with a versioned
N:   python package need a dependency on the equivalent version of python.
N:   
N:   For example, if a script in the package uses #!/usr/bin/python, then
N:   the package needs a dependency on "python". If a script uses
N:   #!/usr/bin/python2.2, then the package need a dependency on
N:   "python2.2".
N:   
N:   In some cases a weaker relationship, such as Suggests or Recommends,
N:   will be more appropriate.
N:

  However:
vdanjean@cayuga:~/debian/mainteneur/tailor$ dpkg --info tailor_0.9.26-1_all.deb
[...]
 Depends: python2.4, python (>= 2.4) | python2.4, python-support (>= 0.2)

 Suggests: cvs, subversion, darcs, mercurial, monotone, codeville, bzr, bazaar, cogito, tla
 Conflicts: bzr (<< 0.7), mercurial (<< 0.9.1)

  Looking at lintian internal, I see that it badly builds $deps{all}
(near line 226 in checks/scripts) due to newlines. The following patch
fixes it:

--- scripts.orig	2006-08-29 12:33:41.000000000 +0200
+++ scripts	2006-08-29 12:32:19.000000000 +0200

 }
 $all_deps .= ', ' if $all_deps;
 $all_deps .= $pkg;
+$all_deps =~ s/\n/, /g;
 $deps{all} = Dep::parse($all_deps);
 
 open(SCRIPTS, "scripts") or fail("cannot open lintian scripts file: $!");


  Best regards,
    Vincent

PS: this can be related to #380286 (some keywords are the same but I do
not really check)
