simsor / kindle-doom Goto Github PK

Hi,

First of all, great project!

I ran in to a bit of an issue earlier today after running ./run.sh manually and thought it may be worth documenting how I fixed it and maybe providing some script considerations for run.sh to prevent it from happening to anyone else.

I ran run.sh manually today via an ssh session and later ctrl + c'ed the script when I was done running doom. I knew due to the ctrl + c that /etc/init.d/framework start would have never ran, so I invoked that manually too. My kindle then went into a framework restart loop and eventually entered an unclean state where even after subsequent reboots, I was presented with the dreaded "Your kindle needs repair" message.

I still had ssh access though and was able to step through a run of /etc/init.d/framework start to find out that the repair message was being displayed on the back of the contents of /var/local/system/.framework_reboots being >= 2.

I was able to exit the repair screen by removing this file and rebooting, I think setting the contents to a number less than 2 would have also worked.

So as for the script, I have done a bit of debugging and it appears you have windows line endings in run.sh inside your releases (not in the actual repo itself):

#!/bin/sh^M
^M
/etc/init.d/framework stop^M
/usr/bin/lipc-set-prop -- com.lab126.powerd preventScreenSaver 1^M
./prboom -iwad /mnt/us/doom.wad -file /mnt/us/prboom.wad -nosound -nomusic -nosfx -warp 1 1^M
/usr/bin/lipc-set-prop -- com.lab126.powerd preventScreenSaver 0^M
/etc/init.d/framework start     ^M

This causes the last argument of most lines in the script to be invalidated, so in the case of /etc/init.d/framework stop^M, this prevents execution:

+ /etc/init.d/framework stop
system: W framework:def:Usage: /etc/init.d/framework {startx|start|stop|reset|restart|force-reload}

So in my case, the repair issue was actually user error. As I assumed that the framework was in a stopped state and attempted to start it, causing problems. However due to those line endings the only command that actually works in run.sh is probably the ./prboom command at present. So probably worth fixing this.

Cheers,
