And in fact, that's not what you likely want. You +</I>><i> want a mirror that is fast enough to be limited by your current network +</I>><i> connexion. If the ADSL connexion is full, that the mirror is giving 10 +</I>><i> or 100 mo directly to you doesn't matter much. +</I> +At Mandriva we had mirrors with much less bandwidth. So, I may have +been wrong in this point. You can't easily check the speed *before* +each transaction. But urpmi/rpmdrake should have an option to switch +to a different mirror if it turns out that the system has chosen a +mirror with low bandwidth. Of yourse, if we only accept mirrors with +><i>= 100MBit then this is obsolete. +</I> +><i> 1) what is the current system ( I think it is based on the geographical +</I>><i> position, which is a very very broad assumption, it help mostly to avoid +</I>><i> brasil people fetching stuff from europa and thing like that ) +</I> +Result is that they may be pointed to ibiblio - which is not really +helpful for them. + +><i> 2) when did it gone wrong ( ie, the mirror that was selected and that +</I>><i> shouldn't, and why, and how could we discriminate for a user ) +</I> +The selection can be wrong from several causes: + - it is not uptodate + - it is not reachable or has a shaky connection (very often the case +with some Mandriva mirrors in Germany and East Europe) + - it has an error in its hdlist (or whatever reasons an update can +not performed correctly from this mirror) + +To make it easy we could leave all prior checks out but invent an +option for the user to switch to a different mirror on the list in +case of such problems. + +>><i>  - checks the update status of the mirror before using it +</I>><i> usually, for non cooker/cauldron, this is likely not a issue. Release is +</I>><i> frozen, at worst, you have a security update being late. +</I> +It's an issue with all update branches of non-cauldron. + +><i> On the other hand, we cannot force people to sync every 2h, and if a +</I>><i> tier2 mirror sync every day, it can quickly become out of the list +</I>><i> depending on the limit. If someone sync on a tier2 mirror that is +</I>><i> already late ( for some network related reason, like in australia where +</I>><i> the country is not that well connected to the rest of the world ), it +</I>><i> will also be more late, and that would be a bad side effect. +</I> +Yes, but if it is late it is late, no matter what the reason, as a +user I would want to have the option to switch to another mirror which +is not late. + +>><i>  - switches to another mirror if the selected mirror is not reachable +</I>>><i> or not uptodate +</I>><i> I tried to fix that part, but unfortunately, the code is "suboptimal". +</I>><i> OTOH, using a manual mirror do not switch to a better mirror in case of +</I>><i> problem too ( IIRC ). +</I> +That's right. But when I select a mirror manually I would select one +which is known as reliable, if that one is broke once in a lifetime I +would not switch but wait. + +But reading all this I realize that we put much too much energy into +this discussion. As I wrote earlier in this thread I totally +understand that there may be technical or other reasons which may +stand in the way of changing something here. So, what would happen if +we do not change anything wrt this issue? +1. Users will go on using the mirrorlist system, no problem. +2. Users who know what to do will use their favourite mirror. +3. Soon we will have some 3rd party putting up a webtool as EasyUrpmi +or SmartUrpmi somewhere and this whole thread is obsolete. + +-- +wobo +</PRE> + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="004338.html">[Mageia-discuss] Easyurpmi forMageia ? +</A></li> + <LI>Next message: <A HREF="004343.html">[Mageia-discuss] Easyurpmi forMageia ? +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#4342">[ date ]</a> + <a href="thread.html#4342">[ thread ]</a> + <a href="subject.html#4342">[ subject ]</a> + <a href="author.html#4342">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://www.mageia.org/mailman/listinfo/mageia-discuss">More information about the Mageia-discuss +mailing list</a><br> +</body></html> |
