Bug#1134628: buildinfo: looks like architecture $foo, but this is not listed in the Architecture-Header!

[Johannes Schauer Marin Rodrigues]

Package: reprepro
Version: 5.4.8-1
Severity: normal

Hi,

when enabling includebuildinfos, reprepro does not seem to like buildinfo files
of source packages that only build Architecture:all packages:

Here is a reproducer:

---%<---------------------------------------------------------------------
mkdir -p conf
cat << END > conf/distributions
Codename: sid
Suite: unstable
Architectures: arm64
Components: main
UDebComponents: main
Description: dummy
Tracking: minimal includebuildinfos
END

cat << END > dummy_0_arm64.changes
Format: 1.8
Date: Thu, 01 Jan 1970 01:00:00 +0100
Source: dummy
Binary: dummy
Architecture: all
Version: 0
Distribution: unstable
Maintainer: dummy
Files:
 da2f9e7c530e45bb3b3b26c89b6a88ee 26 misc optional dummy_0_arm64.buildinfo
 d41d8cd98f00b204e9800998ecf8427e 0 misc optional dummy_0_all.deb
END

echo Build-Architecture: arm64 > dummy_0_arm64.buildinfo
: > dummy_0_all.deb

# the following will error out with:
# 'dummy_0_arm64.buildinfo' looks like architecture 'arm64', but this is not listed in the Architecture-Header!
# To ignore use --ignore=surprisingarch.
# There have been errors!
./reprepro include unstable dummy_0_arm64.changes
--->%---------------------------------------------------------------------

I'd expect reprepro to be able to include a dummy_0_arm64.buildinfo file which
was built on arm64 even though it does not reference any arm64 binaries as
indicated by the Architecture header of the .changes file.

Thanks!

cheers, josch
