ImportsPass

io.joern.jssrc2cpg.passes.ImportsPass
class ImportsPass(cpg: Cpg) extends XImportsPass

This pass creates IMPORT nodes by looking for calls to require. IMPORT nodes are linked to existing dependency nodes, or, if no suitable dependency node exists, a dependency node is created.

TODO with this, we can have multiple IMPORT nodes that point to the same call: one created during AST creation, and one using this pass.

TODO Dependency node creation is still missing.

WARNING: runOnPart is executed in parallel to committing of graph modifications. The upshot is that it is unsafe to read ANY data from cpg, on pain of bad race conditions

Only use ConcurrentWriterCpgPass if you are very sure that you avoid races.

E.g. adding a CFG edge to node X races with reading an AST edge of node X.

override def runWithBuilder(externalBuilder: DiffGraphBuilder): Int

Runs the cpg pass, adding changes to the passed builder. Use with caution -- API is unstable. Returns max(nParts, 1), where nParts is either the number of parallel parts, or the number of iterarator elements in case of legacy passes. Includes init() and finish() logic.

Wraps runWithBuilder with logging, and swallows raised exceptions. Use with caution -- API is unstable. A return value of -1 indicates failure, otherwise the return value of runWithBuilder is passed through.
