Package: edos-distcheck
Version: 1.4.2-11
Severity: important

Dear edos-distcheck maintainers,

edos-debcheck is used by the Debian wanna-build database, used
by the build dæmons to check which packages need rebuilding.
However, it appears that edos-debcheck can't yet cope with
architecture wildcards which are now permitted in package
dependencies and build-dependencies and are supported by
dpkg, sbuild and associated tools.  [I didn't see any use of
dpkg-architecture in the sources.]

Please could you consider adding support for architecture
wildcards with dpkg-architecture?  edos-debcheck support is the
last remaining tool needing support, which is blocking use of
wildcards in Debian.

Support is very simple.  When you get an architecture in
square brackets in a dependency such as

  grub [i386]
  libfreeimage-dev [!linux-any]
  libpng12-dev [any-i386]

you call dpkg-architecture to query if the wildcard matches
the host architecture.  You need to handle the '!' (not) case
yourself.  If the host architecture and dependency architecture
are a straight match, you can skip calling dpkg-architecture if you
want a small optimisation, or else you just ask dpkg-architecture:

Is [linux-any] needed on an amd64 arch?
% dpkg-architecture -aamd64 -ilinux-any 
% echo $?
0
(yes, it matches)

Is [linux-any] needed on a hurd-i386 arch?
% dpkg-architecture -ahurd-i386 -ilinux-any
% echo $?                                  
1
(no, it doesn't match)

Is [any-i386] needed on a hurd-i386 arch?
% dpkg-architecture -ahurd-i386 '-iany-i386' 
% echo $?                                   
0
(yes, it matches)

I'm sure you get the idea!

The list thread link above has the patch written for wanna-build
in it which might be useful as an example of how it could be done.


Many thanks,
Roger Leigh

Hello, edos-distcheck is now superseded by dose-distcheck which is fully
multiarch aware.

Cheers -Ralf.
