Proposed solutions often cloud the thinking about the +problem itself. + + +So putting "Requires(pre): systemd-units" in all packages providing a +systemd unit seems wrong (it doesn't require systemd-units at all, so +this is a fake requires). + +Putting "Requires(pre): rpm-helper >= $ver" also seems somewhat overkill +and hard to maintain (e.g. what if some other new thing goes into +rpm-helper? We have to rebuild all packages that use any of the macros +inside it to get the appropriate versioned require which seems awkward +and hard to maintain[1]). + +Wouldn't it simply be easier to make the installer aware of priority +updates? That way we don't need to maintain different or convoluted +solutions for the same problem. + +I suspect problems like this have been present in the past but were less +noticeable due to the minor differences in rpm-helper package. This time +round it's obviously quite important! + +Col + + +1. By "hard to maintain" I don't really mean in individual specs (it +should be simple enough to parse out any use of the rpm-helper macros +from a spec and automatically add a "Requires(post|preun): rpm-helper >= +$curver" automatically), but rather knowing to rebuild all the packages +as and when needed. It would be nice to now worry about this as a packager. + + +-- + +Colin Guthrie +colin(at)mageia.org +<A HREF="http://colin.guthr.ie/">http://colin.guthr.ie/</A> + +Day Job: + Tribalogic Limited <A HREF="http://www.tribalogic.net/">http://www.tribalogic.net/</A> +Open Source: + Mageia Contributor <A HREF="http://www.mageia.org/">http://www.mageia.org/</A> + PulseAudio Hacker <A HREF="http://www.pulseaudio.org/">http://www.pulseaudio.org/</A> + Trac Hacker <A HREF="http://trac.edgewall.org/">http://trac.edgewall.org/</A> +</PRE> + + + + + + + + + + + + + + + + + + + + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="014340.html">[Mageia-dev] RFC: Add versioned require in rpm on rpm-helper +</A></li> + <LI>Next message: <A HREF="014344.html">[Mageia-dev] RFC: Add versioned require in rpm on rpm-helper +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#14341">[ date ]</a> + <a href="thread.html#14341">[ thread ]</a> + <a href="subject.html#14341">[ subject ]</a> + <a href="author.html#14341">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://www.mageia.org/mailman/listinfo/mageia-dev">More information about the Mageia-dev +mailing list</a><br> +</body></html> |
