stream_processor: fix operator precedence for logical operations

[unitmatrix]

Fixes #3763

Summary

This pull request addresses the issue where the precedence of logical operators (AND, OR, NOT) was not defined in the grammar for the stream processor.

Changes Made

• Added precedence rules for NOT, AND, and OR operators to the Bison grammar file.
  • NOT now has the highest precedence.
  • AND has middle precedence.
  • OR has the lowest precedence.

Issue Addressed

Fixes GitHub issue: stream_processor: precedence of AND, OR, and NOT not defined in grammar.

Impact

This change ensures that logical operations in conditions are parsed with the correct precedence, aligning with expected logical operation rules.

Testing

Please verify that the logical operations in conditions are handled correctly according to the new precedence rules.

Feel free to reach out if there are any questions or further adjustments needed.

Thanks @unitmatrix, it would be great if the syntax (https://github.com/fluent/fluent-bit/tree/master/src/stream_processor#sql-statement-syntax) can be updated based on your changes as well.

Hi @koleini,

Thank you for your feedback. To ensure that I address your request accurately, I revisited my changes and believe they do not impact the existing SQL statement syntax as outlined in the documentation. Could you please specify which part of the syntax might be affected, or if there are specific updates you have in mind? This will help me make the necessary adjustments to the documentation more effectively.

Looking forward to your guidance.
Best regards.
