Recent Changes to DevShell

Recent Changes to DevShell

[Saul Wold]

Chris,

In your recent changes to devshell, you seem to have broken the default 
behavior of setting  TERMCMD / TERMCMDRUN.

When I set them up for scree as follows:

TERMCMD = "${SCREEN_TERMCMD}"
TERMCMDRUN = "${SCREEN_TERMCMDRUN}"

I get a DEBUG message claing to be starting konsole, not screen, also 
there seems to be a problem with the environment being passed as the 
arg3 is related to env:

ERROR: Logfile of failure stored in: 
/vol/1/sgw/autobuilder/yab/yocto-slave/oe-core/build/build/tmp/work/armv5te-poky-linux-gnueabi/lttng-ust-0.15-r2/temp/log.do_devshell.31726
Log data follows:
| DEBUG: Attempting to spawn terminal "konsole"
| ERROR: Error executing a python function in 
/vol/1/sgw/autobuilder/yab/yocto-slave/oe-core/build/meta/recipes-kernel/lttng/lttng-ust_0.15.bb:
| TypeError: execve() arg 3 contains a non-string value
|
| ERROR: The stack trace of python calls that resulted in this 
exception/failure was:
| ERROR:   File "do_devshell", line 6, in <module>

Did you check that this worked correctly with screen?

Thanks
     Sau!

First, this isn't how you configure devshell now. This is a big part
of why I reworked it to begin with, so we'd have better usability. See
the commit messages for details, or just set OE_TERMINAL = 'screen'
(or 'xterm' or 'noop' or 'auto' or..).

This error is just a general bug in the reworked env var exporting I
did per Richard's request, I have a local patch here and will send it
shortly. Sorry about that. No idea why I didn't hit that when doing
the original testing. If you want a temporary local fix, edit
terminal.bbclass, see the env var export bits, and make it check to
see if the value it retrieves is None before adding it to the env for
the terminal. Expect the patch to the list within the hour.
