Description

Addresses #470.

  • Improve query performance:
    • Switch to the correct form of isExcluded avoids calculating (and applying) a list of all excluded elements in the program. (I will put up a separate PR to address other instances of this same problem).
    • Re-implement DefinedMacro with a simpler form of recursion - previously the anyAliasing predicate used recursion in two parts
    • Simplification of where clause, so we only apply a single regex for all cases.
  • Improve detection of macros whose body contains the defined operator after the start of the macro (e.g. #define X Y || defined(Z)).
  • Enable deviations to be applied for this rule.

Change request type

  • Release or process automation (GitHub workflows, internal scripts)
  • Internal documentation
  • External documentation
  • Query files (.ql, .qll, .qls or unit tests)
  • External scripts (analysis report or other code shipped as part of a release)

Rules with added or modified queries

  • No rules added
  • Queries have been added for the following rules:
    • rule number here
  • Queries have been modified for the following rules:
    • M16-1-1

Release change checklist

A change note (development_handbook.md#change-notes) is required for any pull request which modifies:

  • The structure or layout of the release artifacts.
  • The evaluation performance (memory, execution time) of an existing query.
  • The results of an existing query in any circumstance.

If you are only adding new rule queries, a change note is not required.

Author: Is a change note required?

  • Yes
  • No

🚨🚨🚨
Reviewer: Confirm that format of shared queries (not the .qll file, the
.ql file that imports it) is valid by running them within VS Code.

  • Confirmed

Reviewer: Confirm that either a change note is not required or the change note is required and has been added.

  • Confirmed

Query development review checklist

For PRs that add new queries or modify existing queries, the following checklist should be completed by both the author and reviewer:

Author

  • Have all the relevant rule package description files been checked in?
  • Have you verified that the metadata properties of each new query is set appropriately?
  • Do all the unit tests contain both "COMPLIANT" and "NON_COMPLIANT" cases?
  • Are the alert messages properly formatted and consistent with the style guide?
  • Have you run the queries on OpenPilot and verified that the performance and results are acceptable?
    As a rule of thumb, predicates specific to the query should take no more than 1 minute, and for simple queries be under 10 seconds. If this is not the case, this should be highlighted and agreed in the code review process.
  • Does the query have an appropriate level of in-query comments/documentation?
  • Have you considered/identified possible edge cases?
  • Does the query not reinvent features in the standard library?
  • Can the query be simplified further (not golfed!)

  - Optimize query to improve performance
  - Improve detection of macros whose body contains the `defined` operator after the start of the macro (e.g. `#define X Y || defined(Z)`).
  - Enable exclusions to be applied for this rule.
