Extract source URLs from RPM spec files
 

Hi,

I would like to create a probram that would download automatically the
source files of packages given a spec file and build it using rpmbuild.

But I just wonder how to extract the source URLs from the spec file. I can't
use standard srep and sed since often the Source line contains variables
that need to be resolved.

I found that rpm has an option --specfile that seems deigned for that
purpose. But rpm do not seems to be aware of the source filenames
unfortunately.

Does anyone knows how I could extract this information without writing a
spec file parser ?

Thanks.

Mildred

I believe rpmbuild in RPM 5 already does this.

rpm --eval "`cat foo.spec`" will get you most of the way there.

FYI: rpmbuild (in rpm-4.4.6 and later) will already fetch sources/patches,

rpm-4.4.9 will also fetch Icon: url's, as well as verify digests/signatures

of the fetch'ed elements (if the information is added to spec file build dependencies).

Yep. The issue is that there is an ambiguity of exactly what is

being queried with --specfile. The default for --specfile queries all binary

(sub-)packages, as that is arguably more useful to most.

FYI: Here's what is in
rpm-5.0:




$ rpm -q --qf '[%{source}
]' --specsrpm time.spec

* * time-1.7.tar.gz




(I fergit when I implemented --specsrpm, more than a year ago for sure)




which is a start, but does not include (because the *.src.rpm header does not include)

the full URL, only the basename of the included file.




It wouldn't be hard to add the full source URL as an additional tag in *.src.rpm if you want.




Post an RFE to <rpm-devel@rpm5.org> if you (or someone else) wants the ability

to query the full source url from spec files and *.src.rpm headers.
