cdist-troubleshooting(7) ======================== Nico Schottelius <nico-cdist--@--schottelius.org> NAME ---- cdist-troubleshooting - common problems and their solutions 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 "$__manifest/special" % cat ~/.cdist/manifest/special #!/bin/sh echo "Here is an unclean exiting script" somecommandthatdoesnotexist echo "I continue here although previous command failed" -------------------------------------------------------------------------------- We can clearly see that **somecommandthatdoesnotexist** will fail in ~/.cdist/manifest/special. But as the custom script is not called with the -e flag (exit on failure) of shell, it does not lead to an error. And thus cdist sees the exit 0 code of the last echo line instead of the failing command. All scripts executed by cdist carry the -e flag. To prevent the above from happening, there are three solutions available, two of which can be used in the calling script: -------------------------------------------------------------------------------- # Execute as before, but abort on failure sh -e "$__manifest/special" # Source the script in our namespace, runs in a set -e environment: . "$__manifest/special" -------------------------------------------------------------------------------- The third solution is to include a shebang header in every script you write to use the -e flag: -------------------------------------------------------------------------------- % cat ~/.cdist/manifest/special #!/bin/sh -e ... -------------------------------------------------------------------------------- SEE ALSO -------- - cdist(1) - cdist-tutorial(7) COPYING ------- Copyright \(C) 2013 Nico Schottelius.
