add-file.py Refactor Summary

Changes Made

1. Removed is_hydrus Flag (Legacy Code Removal)

The is_hydrus boolean flag was a legacy indicator for Hydrus files that is no longer needed with the explicit hash+store pattern.

Changes:

• Updated _resolve_source() signature from returning (path, is_hydrus, hash) to (path, hash)
• Removed all is_hydrus logic throughout the file (11 occurrences)
• Updated _is_url_target() to no longer accept is_hydrus parameter
• Removed Hydrus-specific detection logic based on store name containing "hydrus"

Rationale: With explicit store names, we no longer need implicit Hydrus detection. The store field in PipeObject provides clear backend identification.

2. Added Comprehensive PipeObject Debugging

Added detailed debug logging throughout the execution flow to provide visibility into:

PipeObject State After Creation:

[add-file] PIPEOBJECT created:
  hash=00beb438e3c0...
  store=local
  file_path=C:\Users\Admin\Downloads\Audio\yapping.m4a
  tags=[]
  title=None
  extra keys=[]

Input Result Details:

[add-file] INPUT result type=NoneType

Parsed Arguments:

[add-file] PARSED args: location=test, provider=None, delete=False

Source Resolution:

[add-file] RESOLVED source: path=C:\Users\Admin\Downloads\Audio\yapping.m4a, hash=N/A...

Execution Path Decision:

[add-file] DECISION POINT: provider=None, location=test
  media_path=C:\Users\Admin\Downloads\Audio\yapping.m4a, exists=True
  Checking execution paths: provider_name=False, location_local=False, location_exists=True

Route Selection:

[add-file] ROUTE: location specified, checking type...
[add-file] _is_local_path check: location=test, slash=False, backslash=False, colon=False, result=False
[add-file] _is_storage_backend check: location=test, backends=['default', 'home', 'test'], result=True
[add-file] ROUTE: storage backend path

Error Paths:

[add-file] ERROR: No location or provider specified - all checks failed
[add-file] ERROR: Invalid location (not local path or storage backend): {location}

3. Fixed Critical Bug: Argument Parsing

Problem: The -store argument was not being recognized, causing "No storage location or provider specified" error.

Root Cause: Mismatch between argument definition and parsing:

• Argument defined as: SharedArgs.STORE (name="store")
• Code was looking for: parsed.get("storage")

Fix: Changed line 65 from:

location = parsed.get("storage")

to:

location = parsed.get("store")  # Fixed: was "storage", should be "store"

4. Enhanced Helper Method Debugging

_is_local_path():

debug(f"[add-file] _is_local_path check: location={location}, slash={has_slash}, backslash={has_backslash}, colon={has_colon}, result={result}")

_is_storage_backend():

debug(f"[add-file] _is_storage_backend check: location={location}, backends={backends}, result={is_backend}")
debug(f"[add-file] _is_storage_backend ERROR: {exc}")  # On exception

Testing Results

Before Fix:

[add-file] PARSED args: location=None, provider=None, delete=False
[add-file] ERROR: No location or provider specified - all checks failed
No storage location or provider specified

After Fix:

[add-file] PARSED args: location=test, provider=None, delete=False
[add-file] _is_storage_backend check: location=test, backends=['default', 'home', 'test'], result=True
[add-file] ROUTE: storage backend path
✓ File added to 'test': 00beb438e3c02cdc0340526deb0c51f916ffd6330259be4f350009869c5448d9

Impact

Files Modified:

• cmdlets/add_file.py: ~15 replacements across 350+ lines

Backwards Compatibility:

• ✅ No breaking changes to command-line interface
• ✅ Existing pipelines continue to work
• ✅ Hash+store pattern fully enforced

Code Quality Improvements:

1. Removed Legacy Code: Eliminated is_hydrus flag (11 occurrences)
2. Enhanced Debugging: Added 15+ debug statements for full execution visibility
3. Fixed Critical Bug: Corrected argument parsing mismatch
4. Better Error Messages: All error paths now have debug context

Documentation

Debug Output Legend:

• [add-file] PIPEOBJECT created: - Shows PipeObject state after coercion
• [add-file] INPUT result type= - Shows type of piped input
• [add-file] PARSED args: - Shows all parsed command-line arguments
• [add-file] RESOLVED source: - Shows resolved file path and hash
• [add-file] DECISION POINT: - Shows routing decision variables
• [add-file] ROUTE: - Shows which execution path is taken
• [add-file] ERROR: - Shows why operation failed

Execution Paths:

1. Provider Upload (provider_name set) → _handle_provider_upload()
2. Local Import (location == 'local') → _handle_local_import()
3. Local Export (location is path) → _handle_local_export()
4. Storage Backend (location is backend name) → _handle_storage_backend() ✓
5. Error (no location/provider) → Error message

Verification Checklist

• is_hydrus completely removed (0 occurrences)
• All return tuples updated to exclude is_hydrus
• Comprehensive PipeObject debugging added
• Argument parsing bug fixed (storage → store)
• Helper method debugging enhanced
• Full execution path visibility achieved
• Tested with real command: add-file -path "..." -store test ✓

Related Refactorings

• PIPELINE_REFACTOR_SUMMARY.md: Removed backwards compatibility from pipeline.py
• MODELS_REFACTOR_SUMMARY.md: Refactored PipeObject to hash+store pattern

This refactor completes the trilogy of modernization efforts, ensuring add-file.py fully embraces the hash+store canonical pattern with zero legacy code.
