[meta-webserver][PATCH] webmin: fix failures in do_install task

[Qi.Chen]

From: Chen Qi <Qi.Chen@windriver.com>

Previously, even if something went wrong in setup.sh script, the do_install
task would still exit successfully. As a result, failures in do_install
task were hidden.

Unlike the setup.sh script shipped with webmin source code, some commands
in our own setup.sh script are possible to fail because we are not installing
webmin on target.

If we examine the log file of the do_install, we can see the following error.

	  Script was not run with full path (failed to find run-postinstalls.pl
	  under /usr/lib64/webmin/webmin)

This patch fixes the above problem. It also adds checks to the return
value of some commands in the setup.sh script so that if the commands
fail, the do_install task will fail too.

Hi Qi,

I'm afraid I don't like the look of this - OECMAKE_PERLNATIVE_DIR is set for 
use by cmake, and perlnative.bbclass should be putting our perl binary into 
PATH so it should be run anyway. Is this change actually necessary?

Cheers,
Paul

Please drop this patch. I found that the do_install task in webmin runs 
some perl scripts (e.g. postinstall.pl and enable-collections.pl) that 
are supposed to be run on target. I suspect webmin has never worked 
correctly on target as a result. I'm gonna propose another fix. The goal 
is to make it work on target.

Best Regards,
Chen Qi

I can assure you that it has worked on the target; at least it did about 6 
months ago (perhaps more by chance rather than design though).

Paul

Hi Paul,

Thanks for your information :)

I just tried it out on sato image with 'webmin' and 'midori' installed.
1) https://localhost:10000
Cannot connect
2) http://localhost:10000
Login page appeared, but I cannot login even if I provided the correct 
username and password.

I did this test on qemu, but I think the result should have nothing to 
do with qemu.

Best Regards,
Chen Qi
