[yast-devel] YaST Tips&Tricks
by Ladislav Slezak 25 Jan '22

25 Jan '22

Hi all, some time ago we discussed where and how we should share "Tips&Tricks" for YaST users and developers. IIRC there was no clear conclusion so I decided to start a wiki [1] to collect all our tricks we know or use. For now it's just a place for dumping your ideas, links, short howtos, etc... When we collect enough data we can probably split it to several categories or move it somewhere else. We just need the data first. I have added there some my tricks from my personal "knowledgebase" file. If you have better tricks or find something wrong simply change it, it's a wiki ;-) Ladislav [1] https://github.com/yast/yast.github.io/wiki/YaST-Tips-and-Tricks -- Ladislav Slezák YaST Developer SUSE LINUX, s.r.o.

Re: [yast-devel] yast-python-bindings issues
by David Mulder 10 Nov '17

10 Nov '17

I've found a way to prevent the crash, although I don't completely understand why (or if this is correct). If I initialize the UI like this prior to calling the Wizard via symbol table lookups, etc (CallYCPFunction in the old python bindings): YUILoader::loadUI(); init_ui(YSettings::loadedUI()); Then I see no crashes or gui artifacts during run, so stack corruption seems resolved (init_ui() is same as from old python bindings). Also, if I tear down YUIComponent when the python program completes (so, prior to the ruby code tearing it down), then I don't see the crash at shutdown, like this: YUIComponent *c = YUIComponent::uiComponent(); if (c) c->result(YCPVoid()); I noticed after loading the UI using YUILoader, that at shutdown I got a segfault in ui_finalizer() (within ruby bindings Yast.cc). It appears that the singleton still holds a pointer, but the pointer is invalid (so it is not null, but the pointer is now invalid). Making that call early resolves the crash.

[yast-devel] configure online repos
by Per Jessen 29 Oct '17

29 Oct '17

Just for the wishlist or for the list of low hanging fruit - when you install from a local repository, it would be really cool to have the URLs of "Online Repositories" adjusted to point there too. For instance, I install from "opensuse.local.hbrz2", but the online repos remain pointing to download.o.o. I looked at this before YaST got converted to Ruby, and it seemed easy to add a "base" url for the repos/. Maybe availabillity of a repo could quickly be checked in the background?
