ERROR IN MANIFEST IS NOT CONSIDERED AN ERROR BY CDIST
|
|
-----------------------------------------------------
|
|
Situation: You are executing other scripts from a manifest.
|
|
This script fails, but cdist does not recognise the error.
|
|
An example script would be something like this:
|
|
|
|
--------------------------------------------------------------------------------
|
|
% cat ~/.cdist/manifest/init
|
|
"$__manifest/special"
|
|
% cat ~/.cdist/manifest/special
|
|
#!/bin/sh
|
|
echo "Here is an unclean exiting script"
|
|
somecommandthatdoesnotexist
|
|
echo "I continue here although previous command failed"
|
|
--------------------------------------------------------------------------------
|
|
|
|
We can clearly see that **somecommandthatdoesnotexist**
|
|
will fail in ~/.cdist/manifest/special. But as the custom
|
|
script is not called with the -e flag (exit on failure) of shell,
|
|
it does not lead to an error. And thus cdist sees the exit 0
|
|
code of the last echo line instead of the failing command.
|
|
|
|
All scripts executed by cdist carry the -e flag.
|
|
To prevent the above from happening, there are two solutions available:
|
|
--------------------------------------------------------------------------------
|
|
# Execute as before, but abort on failure
|
|
sh -e "$__manifest/special"
|
|
|
|
# Source the script in our namespace, runs in a set -e environment:
|
|
. "$__manifest/special"
|
|
--------------------------------------------------------------------------------
|
|
|
