This hourly cronjob was debated yesterday on #ubuntu-devel. For now, we
are keeping it, specially because we changed it so it only runs when
landscape-client itself is running:
<mathiaz> niemeyer: the concern is to put too much load on the servers and
mirrors
<slangasek> mathiaz: I agree that if you're managing a bunch of workstations
centrally, you want the average latency to be much lower than 12h
<niemeyer> mathiaz: Well, I agree.. it would consume less resources from the
server
* warp10 has quit (Read error: 110 (Connection timed out))
<niemeyer> mathiaz: The question, though, is if it makes an important
difference or not
<niemeyer> mathiaz: It does make a difference for Landscape usability
<niemeyer> mathiaz: If you're concerned about it, we can ask elmo about it
<mathiaz> niemeyer: the main raise I'm asking is that the default ubuntu
install (with apt) doesn't update on a hourly basis.
<niemeyer> mathiaz: It's a slightly different use case I guess
<mathiaz> niemeyer: right - if it makes a difference for landscape usability
than a hourly cron job is the best option
<niemeyer> mathiaz: We can always fire APT/Synaptic/whatever and get the
current infomration
<niemeyer> mathiaz: For a server-side solution that's not so practical
* warp10_ is now known as warp10
<slangasek> hmm, on-demand triggering of an update check isn't possible?
<niemeyer> slangasek: It is definitely possible, but it's a bad UI
* effie_jayx has quit (Remote closed the connection)
<slangasek> ok. I imagine it would be a suboptimal user experience regardless,
due to the latency of checking
* seb128 has quit ("Ex-Chat")
<niemeyer> slangasek: Try to imagine something like "The information you're
looking at is 20h old. If you want to know the current updates, click on
Update All Systems and come back in a few minutes."
<slangasek> right :)
* seb128 ([EMAIL PROTECTED]/member/seb128) has joined #ubuntu-devel
<pitti> re (sorry, got some spontaneous guests)
<slangasek> anyway, I'm certainly not arguing against the 1h cronjob
About smart using pkglist from apt, it may happen sometime in the
future, but not now. I can imagine a few people becoming concerned if
suddenly smart used apt's cache, or, as it would indeed happen, "smart
update" also updated apt's cache. It would have to go both ways.
And remember that smart works with more package resolvers/systems than
just apt/deb, so such a solution would probably be better if it were
generalized.
