The difference is that with the new @preserved-rebuild the 'old' library is not deleted until all of the dependent packages have been successfully rebuilt to use the 'new' library. With the old revdep-rebuild mechanism, the 'old' library was deleted during the upgrade emerge. Therefore after the new library was merged, packages which depended on the old library could not be run[1] until these dependent packages were rebuilt to use the new library. [1] Though any which were running at the time the new library was merged would continue to run.

I must obviously be missing something here, if you have the time please, direct me to an adequate source of information or explain a bit, I am curious. Easy. Say you have app x which links to lib y: portage knows that x is linked to say y.1.0.0.so portage then upgrades y and puts y.so.1.0.1.so and the system helpfully thinks to itself hang on a bit, I'm about to remove a library that Y is using. I'd better not do that! and tells you so. (In the meantime you can merge anything you like that links to y.1.0.0.so, this does not affect @preserved-rebuild) You read the message, run @preserved-rebuild and x now links to the new y library. When everything in @preserved-rebuild has been rebuilt, portage knows that now nothing links to the old y library, and removes it. Do you see that the intent is to provide a bridging period where needed libs are not missing? And that @preserved-rebuild and revdep-rebuild do essentially the same function, except: 1. Stuff does not break. OK, make that stuff should not break 2. You don't have to hang around waiting for revdep-rebuild to take ages to run It can go south sometimes, the @preserved-rebuild magic is not always perfect and sometimes it gets confused. There's a file in /var somewhere that records this, so you can just delete it and run revdep-rebuild to get the old behaviour. Sometimes devs do stupid things with what they decide libs are called, and there's nothing portage can do about that except get itself confused (it's not a human and can't infer meaning). I've been using @preserved-rebuild for as long as it's been available (more than a year now?) with very very few hitches. I think you were just unlucky to hit a few stupid packages. There's only one case where this can't work - the developer changes the ABI and does not change the .so version number. That ain't gentoo's fault - shoot the developer.

No big problem, but you clutter your system with old libraries staying in place, and programs still using them do not take possible advantage ob the newer libraries. Wonko

I always hated that and considered it a serious bug. With preserve-libs, things do not break in the first place, because the old libraries are still in place. Ok, well, then the libs are preserved at merge time. Using Alan's analogy, when you update the lib to y.1.0.1.so. It is *at this time* when y.1.0.0 is kept, and that has nothing with using emerge @preserved-rebuild *in the future*. You could still use revdep-rebuild and the effect will be the same (except that old libs will not ever be cleaned if I got it right). Right? So, it's not emerge @preserved-rebuild which fixes the problem (as I said, by the time you run emerge @preserved-rebuild it's already too late, by then the libs are either preserved or broken), but a whole new portage behavior, which is quite different. And maybe only if you have a given FEATURE enabled, which takes this even more far away from the @revdep-rebuild set. So, if this all is correct, this set is intended to *fix* the breakage, just like revdep-rebuild, and *not to prevent* it. It's portage which prevents it by preserving all .so files. Note that revdep-rebuild didn't break anything either. That's false. revdep-rebuild only fixes what portage breaks. It all comes down to one thing: are you using the preserve feature or not? And not the tool you use to fix the binaries. If it didn't work on ~arch, how would it ever make it into arch? I am not the one to answer that, all I can say is that the few times I've tried it, it kept rebuilding the same packages again, and again, and again ad infinitum, as said, I didn't even bother to find what the problem was, because I have a working alternative. Sure it could be better, but that hasn't been the case for me with @preserved-rebuild. I had the same problem with emerge @preserved-rebuild looping endlessly, but that's probably just a minor issue. Just use emerge @preserved-rebuild once to make sure the new libs are being used, and remove /var/lib/portage/preserved_libs_registry afterwards to get rid of the preserved-libs message. That's good to know. However this needs to be fixed, which is probably one of the reasons why portage 2.2 is taking quite a bit to be released. The trouble with revdep-rebuild is that you have to break your system and then fix it. Most of the time this is trivial, but updates like expat-2.0 showed the usefulness of being able to recompile the packages before they were broken. I can't understand that. You CAN'T recompile your packages against the new ABI's until the new ABI is in your system, and hence your system is already broken. There's no preemptive measure against this. Both methods fix the system *after* it's broken. Unless the old and the new ABI version are installed side by side. When @preserved-rebuild is run, it deletes the old libs only after everything left that used it is now linked against the new one. Thanks for the feedback. However there's one thing I can't understand: whether the libraries are kept of removed is decided at the merge time, isn't it? So, whatever breaks, breaks when using emerge to update the offending library, the one that will break the ABI. So, how can using a tool *after that* have any impact over what's broken? It can fix the problem, but so can revdep-rebuild. Again, things do not break in the first place with the preserved-rebuild FEATURE. As a library gets updated, the new library is installed along with the old one. Applications linked to the old one still work. When they are re-compiled, the are linked to the new library, making the old libraries obsolete when this is done for all packages depending on them. I mean: if the old libs with the old abi's are kept, how it

Alan, I haven't followed the introduction of @preserved-rebuild, but you comments make sound like something that happens as emerge is running. Or is it use like its predecessor and ran after a large merge or update? It all happens invisibly as packages are merged with no user interaction.

[gentoo-user] Firefox 3.5 without changing entire system to ~arch?
Could anyone tell me how to install firefox 3.5.x without changing the entire installation to ~arch?

[gentoo-user] mythfrontend problems: no more keyboard, no window borders
I have to admit that I touched a running system again ;-) My thinkpad runs gentoo linux x86, some unstable packages as well, I upgraded to Gnome 2.28 a few days ago. Yes, this could as well got to the mythtv-users-list but I assume the problem isn't with mythtv ... The symptoms: When I start mythfrontend it opens but somehow kills the display of the window borders ... the windowmanager seems to be hit somehow. Alt-Tab doesn't work anymore, the mythfrontend doesn't react to my keyboard, the mouse moves and selects but doesn't set the focus. When I click a gnome-term-windows it doesn't come upfront. ps -ef shows metacity running, I don't see any particular errors in the usual places (/var/log/messages, Xorg.0.log, etc). I reemerged xorg-server (1.6), xorg-drivers, rebuilt a fresh xorg.conf, rebuilt mythtv etc etc AND: Starting OpenOffice shows similar effects! Window border disappears etc. I assume this might have to do with qt somehow? There were quite some qt-related updates as well done ... I do perfectly understand that using unstable packages *could* lead to such a situation. My q is just: Has anyone here seen this as well? Any hint on what path to follow? Downgrade ... ? Thanks in advance for any help ... Stefan

[gentoo-user] program to solve assignment problem?
Is there some simple little program to solve assignment problems? Suppose that someone bought k meat (160), m fish (30) and n milk (15) for 700. So it should solve the equation k * 160 + m * 30 + n * 15 = 700. (A solution happens to be k = 4, m = 2, n = 0. An additional condition could be that he bought at most 6 items; k + m + n = 6. That would eliminate solutions like k = 4, m = 0, n = 4.)

W And maybe it will be easier to just do his own homework instead of letting a computer do it for him. I would like to see how he cheats on test day tho. Think he can bring his puter with him?

That is what I would do, if I couldn't do it on paper... But seriously, this does not belong on this list. Marcus

Re: [gentoo-user] new version of gcc
Harry Putnam rea...@newsguy.com writes: I noticed I've been masking gcc beyond version 4.3.2-r3, and have forgotten why I had it masked. I'm updating world right now, and wondered if I were to move up to most recent gcc (4.4.2), which would be a 5 version jump, what I could expect in the way of problems. Would I need to re-emerge just about everything? No. There is no need to re-emerge when upgrading from gcc-4.3.x to 4.4.x, the ABIs did not change.
