Functional requirements¶

This should be an inexpensive check, and it could help shorten the debug cycle for common job setup problems. e.g., script not under crunch_scripts/, wrong branch specified in script_version, etc.

On job creation or relevant update, validate:

• The specified script exists
• It has the executable bit set

Implementation¶

When the API server is checking the repository, use git ls-tree to verify that the script exists and is executable at the specified script_version.

Verify that this works on Git 1.7.10. If it doesn't, figure out when the necessary Git functionality was added, and document that version requirement.
