recovery_worker

1. Overview

The recovery_worker.cpp file runs selected recovery operations outside the GTK main thread and reports completion.

This is an implementation file. It contains executable logic for the subsystem, including parsing, I/O, validation, recovery flow, or graphical behavior declared by the corresponding interface.

Its paired source or interface file is recovery_worker.hpp.

Primary responsibilities:

  • Accept source, destination and selected results
  • Execute recovery asynchronously
  • Marshal completion back to the UI
  • Support worker lifecycle control

2. File Identity and Scope

  • Source path: src/recovery_worker.cpp
  • Language: C++
  • File role: implementation file
  • Physical lines: 71
  • Non-empty lines: 60
  • SHA-256: b9f821bf42bbc568ad1689e62f11cf0fb7a205e644566c5fc8df387bed97c412

The declarations in this file use the global namespace.

3. Dependencies

3.1 Project Headers

  • recovery_worker.hpp
  • recovery_exporter.hpp

These dependencies define the file’s compile-time integration with the recovery engine, GTK interface, on-disk format decoders, operating-system services, or C++ standard library.

4. Declared Types

No class, structure, or enumeration definition is declared directly in this file.

5. Constants and Configuration Values

No preprocessor or compile-time constants were detected as top-level declarations in this file.

6. Data Members and Persistent State

No class data members are declared directly in this file, or the file primarily implements methods declared elsewhere.

7. API and Function Inventory

The following callable interfaces or definitions were detected:

  • RecoveryWorker::~RecoveryWorker() – Destroys the object and releases resources owned by the instance.
  • void RecoveryWorker::start(const ScanReport&report,const std::string&output_dir,const std::vector<size_t>&selected_result_indices,CompletionCallback cb) – Implements the operation identified by this API and updates or returns the associated state.
  • bool RecoveryWorker::running()const – Implements the operation identified by this API and updates or returns the associated state.
  • void RecoveryWorker::join() – Implements the operation identified by this API and updates or returns the associated state.
  • void RecoveryWorker::request_cancel() – Implements the operation identified by this API and updates or returns the associated state.

8. Operational Flow

The subsystem represented by this file normally participates in the following flow:

  1. Accept source, destination and selected results.
  2. Execute recovery asynchronously.
  3. Marshal completion back to the UI.
  4. Support worker lifecycle control.
  5. Expose or execute the detected APIs: ~RecoveryWorker, start, running, join, request_cancel.
  6. Return explicit results, progress data, recovered records, or diagnostics to the calling layer.

9. Validation and Error Handling

  • Errors are propagated through Boolean results, error strings, logs, exceptions, or status records depending on the API.
  • Byte offsets, sizes and lengths must be validated before arithmetic and before every read to avoid overflow and out-of-bounds access.
  • The implementation contains explicit failure-catching paths and should retain the original diagnostic context.

10. Runtime, Concurrency, and Resource Management

  • Concurrency: the file contains worker-thread or synchronization primitives; UI updates and shared state must remain thread-safe.
  • Error handling: explicit error, exception or optional-result paths are present and form part of the file contract.

11. Security and Data-Recovery Considerations

  • Recovery code should prefer read-only source access and avoid writing to the original damaged medium.
  • Raw devices and image files are treated as untrusted binary input; every offset and length must remain bounded by the source size.
  • Recovered names and destination paths must be sanitized to prevent directory traversal and accidental overwrite outside the selected export directory.

12. Implementation Considerations

  • The implementation should remain aligned with declarations in the paired header and preserve documented return-value semantics.

13. Integration with the Recovery Pipeline

  • The file belongs to the orchestration layer between the UI and low-level parsers.
  • It aggregates progress, results and diagnostics from multiple modules.
  • It should preserve cancellation and completion semantics across thread boundaries.

14. Licensing and Provenance

No explicit copyright or software-license statement was detected in the opening section of this individual file. Distribution terms should therefore be verified against the project-level license and repository metadata.

The SHA-256 value in this document can be used to associate the generated documentation with the exact source version analyzed.
