Introduce two new Connection::InstanceSource subclasses in PEP249.qll: - ConnectionGetterAttributeRead: recognises self._conn reads inside getter methods of classes whose __init__ stores a connect() call in that attribute. The AttrRead node coincides with the return node, so the existing TypeTracker returnStep propagates the connection type to all call sites automatically. - ConnectionConstructorAttributeRead: recognises ClassName()._conn direct attribute reads on constructor-call results. Both classes share the classStoresConnectionInInit helper predicate that checks for the self.attr = dbapi.connect() store pattern in __init__. Also adds test cases for the new patterns in the hdbcli test suite and a change note.
CodeQL
This open source repository contains the standard CodeQL libraries and queries that power GitHub Advanced Security and the other application security products that GitHub makes available to its customers worldwide.
How do I learn CodeQL and run queries?
There is extensive documentation about the CodeQL language, writing CodeQL using the CodeQL extension for Visual Studio Code and using the CodeQL CLI.
Contributing
We welcome contributions to our standard library and standard checks. Do you have an idea for a new check, or how to improve an existing query? Then please go ahead and open a pull request! Before you do, though, please take the time to read our contributing guidelines. You can also consult our style guides to learn how to format your code for consistency and clarity, how to write query metadata, and how to write query help documentation for your query.
For information on contributing to CodeQL documentation, see the "contributing guide" for docs.
