to prevent from syncing with older rsync mirrors, repoman should check timestamp.chk on sync/rsync and switch to an other mirror or stop if timestamp.chk is older than local stored timestamp.chk. if there's no local timestamp.chk, sync should be normal (initial sync) Reproducible: Always Steps to Reproduce: 1. 2. 3.
hi s/repoman/emerge/ ?
One caution with this. The system would have to be in sync with world time in order for this to work. Some systems have clocks that drift pretty badly (linux running on IBM intelliservers comes to mind), so if a system like that is not using ntpd or some method of keeping it's clock synced, before long every mirror would appear to be bad even though they are in the right. That beind said, I think that something along the lines of checking the timestamp is a good idea. Cheers!
Maybe the idea of timestamps should be thrown out as per the caution previously posted, a better solution would be portage tree "versions", some kind of continually increasing number to describe the relative age of a portage tree would be better, as that would have no reliance on the system clock, but rather the rsync mirror lasted sync-ed to. I.e. you initial sync, you get a portage tree version number 13203, next sync your machine finds a mirror that has a portage tree version 13002, so it says, "this is old we don't want to sync to it", and moves on to the next mirror which happens to have a version number 14000, so it's happy! and it syncs up.
I think timestamp.chk is made on master rsync server, which is only one in the world, so we can believe timastamp.chk's date. Is it correct? If so, we can compare timestamp.chk file without making "versions"
If that is so then a timestamp would be fine. A timestamp would probably be easier to implement too, just have to make sure that the timestamp.chk is gotten from the rsync server which is in turn from the master server (that's probably obvious), that way there is no room for variance.
