This PR addresses an issue in the Brain module when writing structured log data to a CSV file. The error encountered is:
Error: need to escape, but no escapechar set
The error occurs when parsing datasets that contain special characters or quotes. By default, pandas.to_csv() does not set an escape character, which leads to a failure when special characters are present in the data.
Solution:
The fix involves explicitly setting the following options when calling to_csv() in generateresult method of LogParser class:
escapechar='\\': Specifies the escape character (\) to handle special characters correctly.
quoting=1 (csv.QUOTE_MINIMAL): Ensures that fields containing special characters (such as commas, quotes, or newlines) are wrapped in quotes.
Checklist:
[x] Code tested with large datasets containing special characters that previously caused the error.
[x] Changes verified to be backward-compatible.
[x] Structured logs (_structured.csv) and event templates (_templates.csv) were successfully written without encountering the escapechar error.
