Symptom:
|
|
running something in a manifest and that fails does not exist
|
|
the cdist run
|
|
|
|
Analysis:
|
|
Find out what the shell does:
|
|
|
|
[23:56] bento:testshell% cat a.sh
|
|
# source something that fails
|
|
. b.sh
|
|
[23:57] bento:testshell% cat b.sh
|
|
nosuchcommand
|
|
[23:57] bento:testshell% sh -e a.sh
|
|
a.sh: 2: .: b.sh: not found
|
|
[23:57] bento:testshell% echo $?
|
|
2
|
|
|
|
-> exit 2 -> looks good
|
|
|
|
|
|
Find out what the python does:
|
|
|
|
[23:57] bento:testshell% python3
|
|

>>> import subprocess

Conclusion:
|
|
Manifests that execute (!) other shell scripts does
|
|
not necessarily give the -e flag to the other script
|
|
-> called script can have failures, but exit 0
|
|
if something the last thing executed does exit 0!
|
|
|
|
Solution:
|
|
Instead of doing stuff like
|
|
"$__manifest/special"
|
|
|
|
use
|
|
sh -e "$__manifest/special"
|
|
|
|
or source the script:
|
|
. "$__manifest/special"
|
|
|
|
(runs the script in the same namespace/process as everything in the
|
|
calling script)
