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

Self-Check: PASSED

• SharepointToolbox/Services/FileTransferService.cs: FOUND
• SharepointToolbox.Tests/Services/FileTransferServiceTests.cs: FOUND
• Commit ac74d31: FOUND
