[Build-common-hackers] Bug#322401: cdbs: blindly adds build-depends that are already present

[Marc Haber]

Package: cdbs
Version: 0.4.32
Severity: normal

I have a package which triggers #300465. I'd like that package to
build depend on cdbs >= 0.4.29 which is the first version that the bug
is fixed in.

So, I modified control.in to say
Build-Depends: @cdbs@, cdbs (>= 0.4.29)
which cdbs promptly converted into a broken
Build-Depends: cdbs (>= 0.4.23-1.1), build-essential, debhelper (>= 4.1.0), dpatch, cdbs (>= 0.4.29)

IMO, cdbs should detect whether there is already a dependency against
a given package and refrain from adding another one. The maintained
should be able to override cdbs' decision.

Greetings
Marc
