Created ControlFlowGraphShared.qll — contains the full GoCfg module with: Ast module implementing AstSig<Location> — maps Go's AST types to the shared interface, with empty types for constructs Go doesn't have (while/do/try/catch/throw/ternary/null-coalescing) Input module implementing InputSig1 + InputSig2 — labels, conditional contexts, custom step() predicates for if-with-init, for/range loops, expression/type switches, case clauses, select, defer, and go statements; abrupt completions for panics, fallthrough, and goto Make0/Make1/Make2 wiring and import Public Modified ControlFlowGraph.qll — added import of the shared library and re-exports it as module SharedCfg = GoCfg, making shared types accessible as SharedCfg::ControlFlowNode, SharedCfg::ControlFlow::EntryNode, SharedCfg::BasicBlock, etc. No breakage — all 90 src queries and library files compile cleanly.
Go analysis support for CodeQL
This sub-folder contains the extractor, CodeQL libraries, and queries that power Go support for CodeQL.
It contains two major components:
- an extractor, itself written in Go, that parses Go source code and converts it into a database that can be queried using CodeQL.
- static analysis libraries and queries written in CodeQL that can be used to analyze such a database to find coding mistakes or security vulnerabilities.
Usage
To analyze a Go codebase, either use the CodeQL command-line interface to create a database yourself, or download a pre-built database from GitHub.com. You can then run any of the queries contained in this repository either on the command line or using the VS Code extension.
