ncurses 6.1 is currently masked: # Lars Wendler <polynomial-c@gentoo.org> (28 Jan 2018) # Masked for testing. # At least app-misc/mc is broken when using a 256color TERM setting. =sys-libs/ncurses-6.1 There are four open security bugs for ncurses (625830, 629276, 624644, 639706) which as far as I can see are all fixed in 6.1, so we should push unmasking forward and track what's needed for it. The comment mentions an issue with mc, but no reference to a bug, either upstream or in Gentoo. Lars, can we have a clarification what the problem here is?

Lars, can we have a clarification what the problem > here is? I haven't investigated deeply because I haven't found a VCS tracker for the terminfo file which seems to be the cause for the issue with mc. Here's what I have found out: app-misc/mc[slang] on a terminaml with 256color support (TERM="*-256color") is completely broken. The input dialogs don't show up, no hilighting, wrong colors in mcedit. Some non-256color terminfos are affected as well but I found not a single 256color terminfo setting that works. app-misc/mc[-slang] behaves better but has other issues unrelated to ncurses. Replacing the terminfo file shipped with ncurses-6.1 with the one from ncurses-6.0 fixes all issues with mc. I haven't reported this to mc, slang or ncurses upstream because I still don't know which package is to blame here. This is the only issue I have found but I want to have some more testing from other people because I won't want people to use potentially broken terminfo files.
I've found reports from other distros that this is an issue with sys-libs/slang: https://bugs.archlinux.org/task/57300 https://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1585785.html So all we need to do is updating the slang package. I'm working on adding their latest snapshot release...
