Description Jeremy Katz 2008-04-15 20:58:14 UTC

Interesting little behavior with depsolving for festival.  It requires
festival-voice and festvox-arctic-hts.  The latter provides festival-voice.  But
there's a shorter named provider too.  Hence, they both get pulled in somewhat
unnecessarily.

Comment 1 James Antill 2008-04-15 21:27:05 UTC

 This doesn't stand much chance of getting fixed in the short term. as it
basically requires "weak deps" in our depsolver ... and it's painful.

 However there is a simplish work around, atm. festival.spec has:

Requires: festival-voice
[...]
Requires: festvox-slt-arctic-hts

...and AFAIK the deps. come out of rpmbuild in the order it sees them, so if you
reverse the above two lines rpm will record the deps. in the opposite order and
yum will process them in the opposite order and so see that -voice is already
satisfied when it comes to look for it.

 I'm 99% this will all work, but no guarantees :).

Comment 2 Jeremy Katz 2008-04-15 21:29:29 UTC

We should fix it some day though :)

Comment 3 Bug Zapper 2008-05-14 09:30:23 UTC

Changing version to '9' as part of upcoming Fedora 9 GA.

Comment 6 James Antill 2010-04-29 20:58:11 UTC

We now count the direct deps. ... this might have fixed the above case, but the pkg. is fixed anyway.
Doing anything much harder than that would probably be painful, in the short term. ... so I'm going to close this.
