Hi folks.
I've "hacked" together a small patch the last few days to basically
convert yum-builddep to always use specfiles for build dep
resolution.
It does so by extracting the specfile from srpms to a temporary
file and uses that then to generate the build dependencies.
The advantage here is obviously that this way yum-builddep would
become arch agnostic and the year old problem of srpms actually
being binary rpms would be solved.
So, AIUI, this won't fix that. As koji/etc. would need to be fixed
for that to happen for distros. ... and AFAIK koji doesn't use
yum-builddep. Pretty much everyone outside a distro. only cares about
one arch, and most don't use yum-builddep either ;).
Saying that, a bunch of people have wanted this feature, so I don't
see a reason to not give it to them. Two things though:
1. It'd be nice to put the code to extract the file somewhere outside
of yum-builddep ... maybe into yum itself, maybe somewhere else. Also
providing a "repoquery --specfile" would be pretty cool (even cooler
if it did arbitrary files in the rpm).
the extraction code would make good sense in rpmUtils somewhere, I
think.

Good points James and Seth, will work on that once the manager visit is
over. ;)
Regarding the repoquery, would something like a "repoquery
--extractfile" work as an additional interface? Not sure if we'd then
need the specific "repoquery --specfile", although it could be used as a
easy way to extract that if you don't know the name. But ye, a general
extractor should be easy enough with the framework in rpmUtils in place.
Would also mean that i could provide a generic file extraction interface
in rpmUtils, so even if the archive format changes in rpm (like it does
currently ;) the external interface would stay the same.
Let me know what you think and i'll ponder a bit myself as well how to
do it properly.
Thanks & regards, Phil
