I was wrong here, the for-loop returns as soon as it finds a valid
entry. I left the order as it is and just added a few debug statements.
After installing the new compiled libcurses, when i start a new terminal,
it tries to lookup existing information in existing databases, and
once an entry is found, it is used immediately. Only when no database
contains an entry for the terminal, a terminfo file is read:
>> _nc_read_bsd_terminfo_entry: Description of stnew-256color in
/home/nils/.terminfo
>> _nc_lookup_bsd_terminfo_entry: tn=stnew-256color,
filename=/home/nils/.terminfo
>> _nc_lookup_bsd_terminfo_entry: Read entries for stnew-256color
from /home/nils/.terminfo
>> _nc_read_bsd_terminfo_entry: not found! Should continue.
>> _nc_read_bsd_terminfo_entry: Description of stnew-256color in
/usr/share/misc/terminfo
>> _nc_lookup_bsd_terminfo_entry: tn=stnew-256color,
filename=/usr/share/misc/terminfo
>> _nc_lookup_bsd_terminfo_entry: Read entries for stnew-256color
from /usr/share/misc/terminfo
>> _nc_read_bsd_terminfo_entry: not found! Should continue.
>> _nc_read_bsd_terminfo_file:
filename=/home/nils/.terminfo/s/stnew-256color
>> _nc_lookup_bsd_terminfo_entry: tn=stnew-256color,
filename=/home/nils/.terminfo
Is this intended?
