# Phase 04 Plan 03: FileTransferService Implementation Summary
|
||||
|
||||
**CSOM FileTransferService with MoveCopyUtil copy/move, three conflict policies (Skip/Overwrite/Rename), recursive folder enumeration, and auto-created destination folders**
|
||||
|
||||
## Performance
|
||||
|
||||
- **Duration:** 7 min
|
||||
- **Started:** 2026-04-03T07:56:55Z
|
||||
- **Completed:** 2026-04-03T08:03:19Z
|
||||
- **Tasks:** 2
|
||||
- **Files modified:** 2
|
||||
|
||||
## Accomplishments
|
||||
- Implemented FileTransferService with full CSOM file transfer via MoveCopyUtil.CopyFileByPath and MoveFileByPath
|
||||
- All three conflict policies: Skip (catch ServerException "already exists"), Overwrite (overwrite=true), Rename (KeepBoth=true)
|
||||
- ResourcePath.FromDecodedUrl used for all path operations — handles special characters in filenames
|
||||
- Recursive folder enumeration via CollectFilesRecursiveAsync with system folder filtering
|
||||
- EnsureFolderAsync auto-creates intermediate destination folders before each file transfer
|
||||
- 4 unit tests pass (interface assertion, TransferJob defaults, ConflictPolicy values, TransferMode values); 3 integration tests skip (require live tenant)
|
||||
|
||||
## Task Commits
|
||||
|
||||
Each task was committed atomically:
|
||||
|
||||
1. **Tasks 1+2: FileTransferService + unit tests** - `ac74d31` (feat)
|
||||
|
||||
**Plan metadata:** (to be added in final commit)
|
||||
|
||||
## Files Created/Modified
|
||||
- `SharepointToolbox/Services/FileTransferService.cs` — CSOM file transfer with copy/move/conflict support, recursive enumeration, folder creation
|
||||
- `SharepointToolbox.Tests/Services/FileTransferServiceTests.cs` — 4 passing unit tests + 3 skipped integration tests
|
||||
|
||||
## Decisions Made
|
||||
- Design-time MSBuild compile used for build verification: `dotnet build SharepointToolbox.slnx` fails at WinFX BAML temp project step (pre-existing environment issue unrelated to C# code); verified via `dotnet msbuild -t:Compile -p:DesignTimeBuild=true` which confirms 0 errors; DLL-based test run with `dotnet test *.dll` confirms 4 pass / 3 skip
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
None - plan executed exactly as written.
|
||||
|
||||
The build environment issue (WinFX BAML temp project failure) is a pre-existing condition confirmed to exist on the committed state from plan 04-01. All C# code compiles cleanly via design-time compile. Tests pass against the generated DLL.
|
||||
|
||||
## Issues Encountered
|
||||
|
||||
- `dotnet build SharepointToolbox.slnx` fails at WinFX.targets line 408 — WPF temp project generation writes to relative `obj\` path, fails in bash shell environment. Pre-existing issue affecting all plan builds in this phase. Workaround: use design-time compile and direct DLL test execution. Out-of-scope to fix (would require .csproj or environment changes).
|
||||
|
||||
## User Setup Required
|
||||
|
||||
None - no external service configuration required.
|
||||
|
||||
## Next Phase Readiness
|
||||
- FileTransferService is ready for use in Plan 04-09 (FileTransferViewModel + View)
|
||||
- BulkOperationRunner pattern established in 04-01 and confirmed working in 04-03
|
||||
- CSOM MoveCopyUtil patterns documented for any future cross-site file operations
|
||||
|
||||

||||
- SharepointToolbox/Services/FileTransferService.cs: FOUND
|
||||
- SharepointToolbox.Tests/Services/FileTransferServiceTests.cs: FOUND
