 Posted: Fri Jun 29, 2018 9:35 am Post subject: kde-sunset: where does the IUSE=webkit come from? [solved] |
 |
|
Hi all,
After a brutal kde-frameworks 5.43-5.46 and dev-qt 5.9.5-5.9.6 upgrade, emerge is still unable to make its way to happiness. On account of KDE 4 being mostly removed from the tree, I am trying to migrate some packages to the kde-sunset version but a IUSE dependency is coming from apparently nowhere:
| emerge -auND world: | emerge: there are no ebuilds built with USE flags to satisfy "kde-frameworks/kdelibs:4[webkit?]".
!!! One of the following packages is required to complete your request:
- kde-frameworks/kdelibs-4.14.37::kde-sunset (Missing IUSE: webkit)
(dependency required by "kde-apps/kdebase-kioslaves-16.04.3-r2::kde-sunset" [ebuild])
(dependency required by "media-sound/amarok-2.8.90-r5::kde-sunset" [installed])
(dependency required by "@selected" [set])
(dependency required by "@world" [argument]) |
Here is kde-apps/kdebase-kioslaves.
| kdebase-kioslaves-16.04.3-r2.ebuild: | RDEPEND="${DEPEND}
$(add_kdeframeworks_dep kdelibs 'bzip2?,lzma?') |
Here is add_kdeframeworks_dep function, no mention of webkit that I can see.
emerge --info kde-apps/kdebase-kioslaves
emerge --info kde-frameworks/kdelibs::kde-sunset

| Such is the broken nature of an unmaintained dumping ground (kde-sunset).why not try to fix your tree upgrade first? |

I do not understand. Are you referring to my comment about the kde-frameworks and dev-qt packages? I have already sorted out those slot conflicts, though it was tedious.

Yes, I misinterpreted your sentence.
When you look at the kdebase-kioslaves ebuild, you'll find the following right on top in the first few lines:
| Code: | | WEBKIT_REQUIRED="optional" |
That means kdebase-kioslaves will have USE=webkit and if selected, depends on kdelibs[webkit]. So switch off webkit for kdebase-kioslaves.
See also:
| Code: | | equery u kdebase-kioslaves |
Looking at ebuilds often does not tell you half the story, so better use equery for such investigations. |

Hey, thanks!
USE=+webkit does show up in equery u kdebase-kioslaves as you mentioned. I couldn't tease apart the relationship between the 'WEBKIT_REQUIRED="optional"' line and the USE dependencies.
However, while adding "kde-apps/kdebase-kioslaves -webkit" does now show the flag disabled for kdebase-kioslaves in equery u, the behavior of emerge is unaffected. I am wondering if there's some sort of cached USE dependency information somewhere, maybe in /var/db/pkg or something that makes this so persistent. I'm pretty hesitant to just emerge -C kdebase-kioslaves as that could break Amarok without an apparent way to get portage to rebuild kdebase-kioslaves if that doesn't work.

Well, if not equery u, emerge -va also shows you all the use flags at the time...
Surely the emerge output is now different than before?

I know, right? It surely sounded like the solution to me:
| emerge -auND world: | These are the packages that would be merged, in order:
Calculating dependencies... done!
emerge: there are no ebuilds built with USE flags to satisfy "kde-frameworks/kdelibs:4[webkit?]".
!!! One of the following packages is required to complete your request:
- kde-frameworks/kdelibs-4.14.37::kde-sunset (Missing IUSE: webkit)
(dependency required by "kde-apps/kdebase-kioslaves-16.04.3-r2::kde-sunset" [ebuild])
(dependency required by "media-sound/amarok-2.8.90-r5::kde-sunset" [installed])
(dependency required by "@selected" [set])
(dependency required by "@world" [argument]) |
| equery u kdebase-kioslaves: | [ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for kde-apps/kdebase-kioslaves-16.04.3-r2:
U I
+ + bzip2 : Use the bzlib compression library
- - debug : Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see
https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
+ + exif : Add support for reading EXIF headers from JPEG and TIFF images
+ + handbook : Enable handbooks generation for packages by KDE
- - lzma : Support for LZMA (de)compression algorithm
- - openexr : Support for the OpenEXR graphics file format
- - samba : Add support for SAMBA (Windows File and Printer sharing)
+ + sftp : Enable SFTP protocol support using net-libs/libssh
- - webkit : Add support for the WebKit HTML rendering/layout engine
|
edit: I have emerge -v enabled in EMERGE_DEFAULT_OPTS

| The problem is missing IUSE, not a disabled USE flag. The requiring package expects kde-frameworks/kdelibs to have a USE flag webkit, but no such flag is found. Since both packages come from the same overlay, this looks to me like a bug that the overlay maintainer needs to address. Either kde-frameworks/kdelibs needs to gain the USE flag, the requiring package needs to not inspect it, or the requiring package needs a USE-default for it. |

The overlay is listed as unmaintained, though? The git repo shows changes, dunno who would handle this issue.
I went on an adventure, and implemented a sort of situation-specific RDEPEND=kde-frameworks/kdelibs:4[webkit(?)] in the eclass that was creating this dependency. | fix-kdebase-kioslaves.patch: | --- eclass/kde4-base.eclass.old 2018-05-14 04:20:32.744691284 -0500

emerge is happier now, and amarok still works.

It is a dumping ground, as I pointed out earlier, a maintenance-free zone.
@ascendant: I've re-added webkit flag to kdelibs, among a few other things, which should make your workaround obsolete. |

Moved from Portage & Programming to Unsupported Software.
Since this is about an unsupported overlay, it fits better here.

..he says right after the "unsupported" overlay gets fixed.
Thanks, asturm

It may be a dumping ground with minimal support or committed maintenance, but someone(s) (apparently including you) must have write access to it. Those someone(s) are the ones who need to know there is a problem before they can fix it. Maybe they will decide to ignore the problem report because it is not worth the trouble. Maybe, as in this case, someone will fix it once the problem is reported. |
