This is the line to start emacs # start a detached session with an emacs server # user's TERM (or 'vt100' in case user's TERM is known dumb # or unknown) is given to dtach which assumes a minimally # VT100-compatible terminal -- and emacs inherits that TERM=$SMART_TERM dtach -n "$TEST_TMPDIR/emacs-dtach-socket.$$" \ sh -c "stty rows 24 cols 80; exec '$TMP_DIRECTORY/run_emacs' \ --no-window-system \ $load_emacs_tests \ --eval '(setq server-name \"$server_name\")' \ --eval '(server-start)' \ --eval '(orphan-watchdog $$)'" || return my first guess: SMART_TERM is 'screen', and terminfo for that is missing if not, then some TTY problem, which may break dtach, and if not dtach, then emacs my usual try is strace(1): TERM=$SMART_TERM strace -f dtach -n "$TEST_TMPDIR/emacs-dtach-socket.$$" \ sh -c "stty rows 24 cols 80; exec '$TMP_DIRECTORY/run_emacs' \ --no-window-system \ $load_emacs_tests \ --eval '(setq server-name \"$server_name\")' \ --eval '(server-start)' \ --eval '(orphan-watchdog $$)'" & (have to be run in background as strace -f will not exit until every child program have exited...) and then comb through strace output (-o option to strace may be useful...). > > --dkg _______________________________________________ notmuch mailing list notmuch@notmuchmail.org https://notmuchmail.org/mailman/listinfo/notmuch
