State Modification

No Direct State Modifications

Compilation doesn't modify rebar state directly. Changes are to:

  • File system (creates .beam files, etc.)
  • DAGs (updated and saved to disk)
  • App info records (may be updated with compilation metadata)

DAG Updates

For each compiled file:

  • Add/update artifact vertices in DAG
  • Store artifact metadata (options, compiler version)
  • Update timestamps
  • Save DAG to _build/PROFILE/.rebar3/COMPILER/source[_LABEL].dag
