With loglevel DEBUG, the XOS synchronizers will write to the logs when a particular model is saved. This tool pulls the information about object saves from the logs and analyzes it. The goal is to identify potential race conditions caused by the same field being saved from multiple tasks, where a task is a sync step, event step, pull step, or model policy.
For each model, the tool will print a warning if save() was called on a model that hadn't changed (it's better to use save_if_changed()). For fields in the model that were saved from code in two or more files, it will print out the file paths. The idea is that these files should be scrutinized to make sure the object is being updated in a safe way.
In order to run this tool you need to install the pyparsing package. You can do that via this command:
pip install pyparsing
./analyze_logs.sh
