CodeQL library for Python

codeql/python-all 1.0.6 (changelog, source)

Module MakeImpl::Impl

Constructs a data flow computation given a full input configuration.

Import path

import codeql.dataflow.internal.DataFlowImpl

Predicates

flow	Holds if data can flow from `source` to `sink`.
flowPath	Holds if data can flow from `source` to `sink`.
flowTo	Holds if data can flow from some source to `sink`.
flowToExpr	Holds if data can flow from some source to `sink`.

Classes

Ap	Conceptually a list of `Content`s where nested tails are also paired with a `DataFlowType`, but only the first two elements of the list and its length are tracked. If data flows from a source to a given node with a given `AccessPathApprox`, this indicates the sequence of dereference operations needed to get from the value in the node to the tracked object. The `DataFlowType`s indicate the types of the stored values.
ApNil
ApOption
PathNode	A `Node` augmented with a call context (except for sinks) and an access path. Only those `PathNode`s that are reachable from a source, and which can reach a sink, are generated.

Modules

Debug	INTERNAL: Only for debugging.
FlowExplorationFwd
FlowExplorationRev
PathGraph	Provides the query predicates needed to include a graph in a path-problem query.
