Cached Disassembly

The ofrak_cached_disassembly module allows you to load a previously saved disassembly and decompilation analysis at a later time. This avoids performing the analysis more than once.

Usage

Discover the cached disassembly module with:

ofrak = OFRAK(logging.INFO)
ofrak.discover(ofrak_cached_disassembly)

Note: ofrak_pyghidra is currently the only analysis backend that supports storing a disassembly file for loading with ofrak_cached_disassembly.

Saving Cached Analysis

To save a cache to a JSON file, see the ofrak_pyghidra "Saving Cached Analysis" section of the documentation.

Loading Cached Analysis

To load a saved JSON cache file, run the CachedAnalysisAnalyzer:

await resource.run(
    CachedAnalysisAnalyzer,
    config=CachedAnalysisAnalyzerConfig(
        filename="cache_file.json"
    ),
)

Once the cached analysis is loaded, you can run unpack_recursively and analyze_recursively to create the child resources.

Gotchas

The ofrak_cached_disassembly module is an OFRAK backend and cannot be used concurrently with other OFRAK backends. The following code will not work, since you can only use one backend at a time.

ofrak.discover(ofrak_cached_disassembly)
ofrak.discover(ofrak_pyghidra)
