[patch] Terminal spawing
trick at icculus.org
Wed Sep 26 01:25:30 EDT 2007
Hello. Currently MojoSetup just silently fails in the event that all
GUI plugins (except stdio) fails, and there's no stdio available.
The attached patch changes this so that if all GUI plugins fail,
MojoSetup will attempt to launch a terminal, and then relaunch itself
inside that terminal. It seems to work.
A new command-line argument and environment variable is added to
disable this behaviour: -notermspawn and MOJOSETUP_NOTERMSPAWN.
The patch also includes a fix for a segfault when not using an archive
for the files (the fileio.c part).
* This changes the stdio plugin to fail if stdin and stdout are not
connected to a tty unless terminal spawning is disabled, which
obviously means that automated runs of the installer with piped
input/output probably won't work anymore unless the -notermspawn
argument is passed.
* The list of terminals to try is hard-coded (mostly yanked from
MakeSelf). Probably needs tweaking, and it'd be better to try to
get the system default if possible anyway. (xdg?)
* Don't know how portable execvp is..
* A compile-time option to enable/disable this might be nice.
