So you can't just copy 'sources' from one package to another?

[Richard W.M. Jones]

For mingw-* packages we (sometimes) have a separate package from the
native package, eg. libgcrypt vs mingw-libgcrypt.  Therefore two
different packages are sometimes built with the exact same sources.

However I discovered copying 'sources' (ie the file) from libgcrypt
dist-git to mingw-libgcrypt dist-git alone isn't sufficient to get the
package to build.  You still have to download the source tarballs in
libgcrypt, copy them to mingw-libgcrypt, and 'fedpkg new-sources
<tarballs>' to upload them again.

Isn't the lookaside cache shared across the whole of Fedora?

(This doesn't matter, I was just wondering aloud.)

Rich.

Fedora's lookaside schema seems to be
https://src.fedoraproject.org/repo/pkgs/rpms/$pkgname/$filename/$hashtype...,
so it far from being a content-addressed storage
that'd reuse data across different $pkgnames.

Yeah, it's not really designed for easy sharing accross packages. 

It looks up things like: 

https://src.fedoraproject.org/repo/pkgs/rpms/<pkgname>/<source.t...
type>/<checksum>

So, since the package name is in there if you just move it the archive
isn't under that and it doesn't work. ;( 

It would likely need a redesign to support that use case sadly.

you may request an RFE on fedpkg-minimal [1] , fedpkg-minimal is
responsible for download the sources of the packages when koji starts
the builds. Take a look in fedpkg-base [2] is a very simple script , 
It shouldn't be difficult do what you ask, I think, it will be more
complicated define the concept and be accepted by upstream . 

Best regards
