[Bug 1705067] Re: system-local terminfo does not search /usr/share/terminfo as README says

[Thomas Dickey]

Works for me:

$ infocmp stterm|head -5
#       Reconstructed via infocmp from file: /usr/share/terminfo/s/stterm
stterm| Suckless Tools simple terminal,
        am, bce, hs, mir, msgr, ul, xenl,
        colors#8, cols#80, it#8, lines#24, ncv#3, pairs#64,
        acsc=``aaffggiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz{{||}}~~,

$ infocmp -D
/etc/terminfo
/lib/terminfo
/usr/share/terminfo

$ toe -as
--> /etc/terminfo
----> /lib/terminfo
------> /usr/share/terminfo
...
----*-: stterm           Suckless Tools simple terminal
----*-: stterm-256color  Suckless Tools simple terminal with 256 colors
----*-: stterm-meta      Suckless Tools simple terminal with meta key
----*-: stterm-meta-256color     Suckless Tools simple terminal with meta key 

Since /usr/share/terminfo is the compiled-in system default, it's hard
to break that...

Title:
  system-local terminfo does not search /usr/share/terminfo as README
  says

Status in ncurses package in Ubuntu:
  New

Bug description:
      $ lsb_release -rd

      Description:    Ubuntu 16.04.2 LTS
      Release:        16.04

  The file /etc/terminfo/README says

      This directory is for system-local terminfo descriptions. By default,
      ncurses will search ${HOME}/.terminfo first, then /etc/terminfo (this
      directory), then /lib/terminfo, and last not least /usr/share/terminfo.

  but it seems that /usr/share/terminfo is not used or does not work as
  expected?

  Repro:

  1) Install `stterm`

  2) Start `stterm`

  3) Type `clear`

  Result:

      terminals database is inaccessible

  Expected result:

  Screen is cleared

  Workaround:

  Symlink the terminfo database to a user-local ~/.terminfo

      mkdir -p ~/.terminfo/s && ln -sf /usr/share/terminfo/s/stterm*
  ~/.terminfo/s
