Re: [opensuse-factory] [suggestion] YaST-update should NOT refresh all installation-sources when called by opensuse-updater
Well, Herr Kuhlmann, have you ever considered that the average dialup user wouldn't be stupid enough to try applying remote updates over his link? Unless he was incredibly desperate not to have his Apache server hacked XD Almost ALL computers these days have a broadband connection of some form. Really? In which world are you living? Yes, I'm not proud that I used a 33.6k modem up until January 19 2006, but one of the first things i did on my broadband link was download a new distro (i'd been using Fedora Core 4, and as you can imagine it traumatised me for life.) - There's just NO excuse to use a dial-in narrowband data link for anything more than ssh these days. Cheap and plentiful data pipes are available in every developed country of the world Welcome to the real world, where not all users are from the so-called developed countries and where not all internet access are broadband.

In my opinion the update speed is not unimportant. It's true you don't have to look at it and work while YaST is updating your system. But having a slow update system like the one we have at the moment makes clever solutions like delta-rpms useless. Btw, the installer takes exactly the same time to parse data when installing patches or new software, and if I need a new app to do my work, the put on another desktop technique doesn't apply. Moreover, I think the speed of the package manager in elaborating patches information should be negligible in comparison with the patches download time. This often (almost always?) doesn't happen with the current implementation. Regards, Hi Alberto, the point was that a part of the problem are our habits. They make whole situtation worse, and new users that are not used to Linux are hit the most. The parsing speed is what should be improved in 10.3, but what is faster, download or parsing, depends on Internet connection speed, internal computer I/O speed, amount of RAM and CPU speed. For example with my current Internet connection on this computer it is faster to download full size iso than download delta iso and run applydeltaiso combination. Download takes 20-30 minutes per CD and totals in 3 hours. The other option takes lesser to download, but than applydeltaiso runs for approximately one hour per CD. I use slower disk for download archive and that makes situation worse, but applydeltaiso process runs quite nice in background and I use Internet without problems. -- Regards, Rajko. http://en.opensuse.org/Portal - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Uhhm, you're talking about downloading the updates/repodata/*.xml.gz files? For the 10.2 updates that's about 13MB currently. I'd be very interested to hear how you download that over a dialup at a realistic 3kbyte/s in a few seconds tops. Its more like 5 MB. others.xml.gz is not downloaded usually. Also the update source is not relevant here is it? When opensuseupdater tells you that updates are available the update repo has already been refreshed hasn't it? So it won't need to download new metadata again at YOU startup. The problem is the other repos that most people add, Packman and Guru etc. - and this is an even smaller download from what I can tell. But of course any download on dialup is big. I wonder how many people do Windows-update or apt-get upgrade on dialup for comparison. I think for most users parsing metadata takes way longer than downloading updated metadata. At least for me parsing metadata is perhaps 80% of package manager startup time. I do have comparatively high bandwidth I guess (2 mbit), but it's not like I'm on 100 mbit. And I also have an above average machine I guess, and still parsing takes sooo long. Maybe it would still make sense to not update all repos at YOU startup if that would be safe. But I still think many people confuse the metadata-parsing with repo-updating. And I maintain that parsing is the biggest culprit. I support this, and i notice that the cpu consumption is enormous on start, and on and after finishing, i am forced to stop working, because the reaction-speed for my keybord has reduced to -20 secs. ( i mean that a keystroke is visible after 20 secs.) I mean i would realy don't care, if i would not notice any of the update/grades, but they are dominant, and force me to stop working, which is, at least to me, very disturbing... - -- Have a nice day, M9.

What I mainly object to is the repeated downloading of 98% of old metadata and only 2% of new, because everything is packed up in the same binary file. A more intelligent design would be 50 times faster... What about using zsync?

In my opinion the evaluation of how the update system work should be independent from users' habits. We can't think to change their habits, it's a fight lost before it starts. It's easier to change the software, or the user will change it ;-) :-) User experience is master. You know by your self when you are in user role. Habits ... they are part of problem and part of solution. I agree that changing habits is harder task than to rewrite software, but when you know that some solution is more comfortable and productive, than it is time to take on harder to solve part of equation, and that is what my post was about. Of course I did my reasoning thinking to a user who works always on the same machine and with the same connection. That user would notice a huge increase of the update/install time in more recent versions of suse than in past ones (9.3, 10.0), without any advantage for him. Yes, and hopefully opposite direction of changes in 10.3. The download time is related to the connection speed, and the user is accustomed to his connection, so he will accept a long download time if he has a slow connection. On the contrary he will not accept a long parsing time, because it wasn't there before, it's not there in other distributions and in other operating systems. When developing a new software, the key point is to think as the user thinks, and not to try to find excuses to justify problems, or workarounds to make users accept the status quo.

Cheap and plentiful data pipes are available in every developed country of the world - EMBRACE THEM! :D by the by, 13MB on my cable modem? it's demolished in one minute. Hmm, apart from being rather arrogant this answer is also excessivly ingorant of security matters because, what is says boils down to if you are sitting behind a small bandwidth connection (GPRS, modem, ISDN, UMTS) it's OK to connect to the internet but don't download (security) patches. It also fails to take into account users that have to pay for the volume that they use. While it may well be worthwile to download (and pay for the volume) the delta-rpms to have a properly secured Suse the question is: Why should I pay multiple times that volume just to know that my system needs/doesn't need patches. I think it is good practice to check for patches once per day and when comparing the download volume to the checking overhead, the current situation looks bad. In my case, I have a limit of 100 MB per month, after that the megabytes become rather expensive. If I'm on business trips for two weeks, then I'll use up almost all of that volume just to do the checks for updates.
