Second batch of test reblessings, capturing changes in result content (not just toString labels): - Framework taint/concept tests (fastapi, sqlalchemy, aiohttp, lxml, stdlib, django-orm): mostly gained MISSING-tainted annotations where the new dataflow no longer reaches sinks. Some are real taint regressions; left as documented failures for follow-up. - Exception-handler tests (CWE-209-StackTraceExposure, EmptyExcept, CatchingBaseException, IncorrectExceptOrder, FileNotAlwaysClosed, FindSubclass/Find, Statements/exit/UseOfExit): the no-raise shared CFG abstraction does not emit ExceptionSuccessor abrupt-completion edges from arbitrary expressions, so except-handler bodies (and their exception target Names) are statically dead. Tracked separately under cfg-modelling-exceptions. - Dataflow-path / control-flow node toString polish across the security query suite (PathInjection, CodeInjection, UnsafeUnpacking, UnsafeUsageOfClientSideEncryptionVersion, RequestWithoutValidation, ReflectedXss, CallGraph): simple-leaf nodes now stringify as their AST text instead of 'After X'. - SSA / call-graph improvements (CmpTest, CallGraph/InlineCallGraphTest): fewer SSA mismatches between new and old; two previously-MISSING tt= annotations resolved.

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.

The CodeQL CLI (including the CodeQL engine) is hosted in a different repository and is licensed separately. If you'd like to use the CodeQL CLI to analyze closed-source code, you will need a separate commercial license; please contact us for further help.
Visual Studio Code integration
If you use Visual Studio Code to work in this repository, there are a few integration features to make development easier.
CodeQL for Visual Studio Code
You can install the CodeQL for Visual Studio Code extension to get syntax highlighting, IntelliSense, and code navigation for the QL language, as well as unit test support for testing CodeQL libraries and queries.
Tasks
The .vscode/tasks.json file defines custom tasks specific to working in this repository. To invoke one of these tasks, select the Terminal | Run Task... menu option, and then select the desired task from the dropdown. You can also invoke the Tasks: Run Task command from the command palette.
