Description Pacho Ramos gentoo-dev 2013-04-29 22:02:18 UTC
I am trying to skip webkit-gtk rebuilding, and I hit this problem:
# emerge -avuDN world --exclude webkit-gtk --jobs=4 --keep-going

These are the packages that would be merged, in order:

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

Comment 2 Zac Medico gentoo-dev 2013-04-29 22:42:06 UTC
It looks like your arguments caused it to hit the backtracking limit, and it ended up automatically masking the icu update while backtracking.

It probably would have behaved much better if you had used --exclude="icu webkit-gtk", since icu is what triggers the webkit-gtk rebuild (by excluding the icu update, you could have avoided needless backtracking).
Comment 3 Zac Medico gentoo-dev 2013-04-30 05:20:51 UTC
You can try it with a larger --backtrack setting to see if that solves it. If --backtrack=30 doesn't work, maybe try 100 or more.

Thanks, will try this night

Only one more think, maybe would be interesting to show in some way what package is triggering rebuilds, how did you found it was "icu"?

Well, icu seems to change sub-slot at least once a week, so if I was gambling then I would bet on icu. Also, I saw "[ebuild  r  U  ] dev-libs/icu-51.1:0/51.1 [49.1.2:0/0]" in the merge list that you posted on bug 467924, and checked for icu in the webkit-gtk deps like this:

  grep icu /usr/portage/metadata/md5-cache/net-libs/webkit-gtk*

Bug 472104 requests display improvements in this area.
Comment 7 Sebastian Luther (few) 2013-11-29 21:37:42 UTC
Anything that needs to be done here? Note that the display improvements are already implemented (but not released).

what's need to be done here? i can tell.
sub-slot should go away from package manager. You, portage developers, are so far away from understanding what package manager should do. Users should have controllable, clean, straight-forward updates, no blocks, no idiotic message about slots, sub-slots, unresolveable dependencies. We, humble users, who likes Gentoo philosophy and the way we control their systems, are seriously depressed about *declining* portage speed and *performance*. Currently it takes so much time maintaining updates, specially dealing with sub-slots. Portage output is just hilarious, it chokes in an output it generate itself. Is this a package manager does it? Yes. So how, on earth regular user deal with that? --backtrack? Oh c'mon. This is about curing legs, when you have head injury, i'd say. What is sub-slot?
First of all, this is absolutely incorrect term. sub-slot means there is a slot within a slot. Is this true? No, it's not. This artificial, super-smart technique using mind-lowing "graph-theory-based-resolver" which does exactly this idiotic things. In theory, idea of rebuilding packages after a soname bumps is good. The way it's implemented, is absolutely unacceptable. So, we, humble Gentoo users, ask portage devs to stop generate random crap. Call 2016 Year, a Year of Portage, a heart of Gentoo and finally do the heart surgery, do not add shit in package manager. Freeze developement. Freeze EAPI updates. Clean up code, fix resolver. Create something better than sub-slots or fix this feature to be working. Only then release portage version, that are known to not giving so much maintenance burden.

Just set EMERGE_DEFAULT_OPTS="--ignore-built-slot-operator-deps=y" and you won't be bothered with them anymore.

Is there any reason why this can't be the default?  Some of these blocker messages where you have a half dozen packages conflicting are completely incomprehensible.  If I have trouble untangling them what hope does someone who's just starting out have?

Hmm, I suppose that in the event of an unsolved conflict, it would make sense to filter out the noise that comes from the built slot operator deps.

I don't want to disable slot operator rebuilds by default, because it works very well in many cases, especially smaller systems.

It also works very well on larger systems, but that fact tends to be obscured by a bunch of conflicts that are unrelated to built slot operator deps. In this case, it seems like we could greatly benefit by filtering out the noise that comes from the built slot operator deps.
