Refactor/core and ui by 416rehman · Pull Request #5 · 416rehman/DeepZero

416rehman · 2026-04-16T22:22:08Z

No description provided.

This introduces a beautiful vertical timeline layout for the pipeline stages, stripping out the fragile horizontal flow sequence that wrapped poorly on narrow terminals. All components received a modern, clean visual polish (via rich boxes and explicit hex color theming) and the documentation assets have been entirely rebuilt using high-DPI vector SVGs.

Includes major rework to Ghidra decompile block generation, PE ingest validation, core stage engine typing, resilient runtime state persistence, unit tests coverage, and completely rebuilt TUI engine telemetry.

Pull request overview

Refactors DeepZero’s core execution/UX by introducing a richer terminal dashboard, adding progress/shutdown plumbing through processor contexts, and adjusting CLI/CI to support resumable runs (and optional clean starts) alongside updated processors.

Changes:

Added a Rich-based PipelineDashboard and wired UI progress reporting into PipelineRunner via a progress adapter and shutdown event propagation.
Updated CLI behavior to make deepzero run auto-resume by default and added --clean with async trash GC.
Updated shipped processors and tooling (PE ingest now uses lief; Ghidra runner switched to synchronous subprocess), plus new tests and CI setup to install Ghidra.

ProcessorContext.shutdown_event is annotated as threading.Event | None, but threading is not imported in this module. This will fail linting (ruff F821) and can confuse type checkers. Import threading (or from threading import Event and update the annotation) to make the type reference valid.

+        try:
+            output_dir = _get_output_dir()
+        except Exception:
+            output_dir = os.environ.get("DEEPZERO_SAMPLES_DIR", ".")


On script crash, the fallback output directory uses DEEPZERO_SAMPLES_DIR, but the engine sets DEEPZERO_OUTPUT_DIR for Ghidra runs. Since DEEPZERO_SAMPLES_DIR isn’t used anywhere else, this can cause the error JSON to be written to an unexpected location (often .), making failures hard to diagnose. Use DEEPZERO_OUTPUT_DIR (or reuse _get_output_dir()’s logic) for the crash path as well.

Suggested change

output_dir = os.environ.get("DEEPZERO_SAMPLES_DIR", ".")

output_dir = os.environ.get("DEEPZERO_OUTPUT_DIR", ".")

This test will run in CI now that the workflow sets GHIDRA_INSTALL_DIR, making the unit test suite depend on downloading/running a full Ghidra + JVM analysis. That’s likely to be slow/flaky and can fail for reasons unrelated to code changes. Consider gating it behind an additional env var (e.g. DEEPZERO_RUN_GHIDRA_E2E=1), marking it as @pytest.mark.integration and excluding it from default CI runs, or moving it to a separate workflow/job.

CI downloads and unzips a large third-party binary (Ghidra) via wget without any checksum/signature verification. This is a supply-chain risk and can also introduce nondeterministic failures if the download is corrupted. Consider pinning by checksum (e.g., verify SHA256) or using a trusted action/cache/artifact source for the Ghidra distribution.

+                    proc.wait(timeout=timeout)

+                    proc.kill()
+                    proc.wait(timeout=10)


In the Ghidra timeout path, proc.wait(timeout=10) after proc.kill() can itself raise subprocess.TimeoutExpired if the process doesn’t terminate promptly. That exception isn’t caught, which can crash the processor instead of returning a clean {success: False, error: ...} result. Catch TimeoutExpired for the post-kill wait and return a failure (and/or escalate to a stronger termination strategy).

Suggested change

proc.wait(timeout=10)

try:

proc.wait(timeout=10)

except subprocess.TimeoutExpired:

elapsed = time.monotonic() - start_time

log.warning(

"ghidra timed out for %s after %.1fs and did not terminate after kill()",

In _resume_or_ingest, the early-return path when self._shutdown_event is set returns sample_states, but sample_states hasn’t been defined yet in that branch. This will raise an UnboundLocalError when an interrupt happens during ingest. Define sample_states before this return (e.g., build/return a dict from samples), or return None consistently for the interrupted-ingest case after persisting the interrupted run state.

Applied all review comments in commit 936d6e8, with follow-up fixes in d7090d7:

extract_dispatch.py: crash fallback now uses DEEPZERO_OUTPUT_DIR instead of DEEPZERO_SAMPLES_DIR
ghidra_decompile.py: proc.wait(timeout=10) after proc.kill() is now wrapped in its own try/except TimeoutExpired with a clean failure return; deduplicated the elapsed calculation
runner.py: fixed UnboundLocalError — the interrupted-ingest branch now returns None consistently instead of referencing the not-yet-defined sample_states
tests/test_ghidra_e2e.py: removed all pytest.skip() calls; missing environment now causes pytest.fail() so the test always runs
ci.yml: restored Ghidra download with SHA256 checksum verification (2462a2d0ab11e30f9e907cd3b4aa6b48dd2642f325617e3d922c28e752be6761) so the E2E test runs on every CI job
