Add async operations for model reading and calculations (#24) by StreckerCM · Pull Request #33 · StreckerCM/GeoMagSharpGUI

StreckerCM · 2026-02-05T18:03:08Z

Summary

Add async versions of all long-running operations (model reading, calculations, file saving)
Add StatusStrip with progress bar and Cancel button to main form
Add progress reporting via IProgress<T> and CancellationToken support
Add auto-clearing status messages with model names (e.g., "Model loaded: WMM2025")
Add 20 new async unit tests
Keep synchronous methods for backward compatibility
Fix 3 pre-existing bugs in Load Model workflow

Closes #24

Changes

Library (GeoMagSharp)

CalculationProgressInfo - New progress reporting class
ModelReader.ReadAsync() - Async model file parsing with cancellation
GeoMag.MagneticCalculationsAsync() - Async calculation with per-step progress
GeoMag.SaveResultsAsync() - Async file export
MagneticModelCollection.LoadAsync() / SaveAsync() - Async JSON operations
All library async methods use ConfigureAwait(false)

UI (GeoMagGUI)

StatusStrip with progress bar, status label, and Cancel button
Async Calculate, Save, Add Model, and Load Model handlers with progress updates
Escape key and Cancel button for operation cancellation
SetStatusTemporary() - Auto-clearing status messages (5-second timer)
Status messages display model name (e.g., "Model loaded: WMM2025", "Model added: WMM2025")
frmAddModel refactored: constructor picks file, LoadModelDataAsync() called by frmMain
Re-entrancy guards, save guard, null checks
Grid cleared on cancel/error
Accessibility: AccessibleName on all StatusStrip controls

Bugs Fixed in Load Model

Missing path separator (string.Format → Path.Combine())
Model was never parsed into a MagneticModelSet or added to collection
Model never selected in dropdown (was passing file path instead of GUID)

Security

TOCTOU fix: file operations moved inside Task.Run
File.WriteAllText for atomic writes
Inner exception parameter instead of e.ToString() for error messages

Tests

20 new async unit tests covering all async methods
SynchronousProgress test helper (avoids SynchronizationContext race conditions)
Tests for progress reporting, cancellation, round-trip, and sync/async parity
83 total tests (81 pass, 2 skipped for missing DAT files)

Ralph Loop

Completed 4 full cycles (24 iterations), 2 clean cycles achieved
All 6 personas reviewed: Implementer, Reviewer, Tester, UI/UX Designer, Security Auditor, Project Manager

Test Plan

Build succeeds
All 83 unit tests pass (81 passed, 2 skipped)
Ralph Loop: 2 clean cycles with rotating personas
Manual test: Calculate with progress bar visible
Manual test: Cancel mid-calculation
Manual test: Escape key cancels
Manual test: Save results async
Manual test: Add/Load model with status message

[IMPLEMENTER] Review - Iteration 0

Summary

Verified that all implementation tasks from docs/features/03-async-operations/tasks.md are complete. All 8 components pass verification.

Findings

All library async methods use ConfigureAwait(false) correctly
Synchronous methods preserved for backward compatibility
Progress reporting uses standard IProgress<T> pattern
CancellationToken properly propagated through all async call chains
StatusStrip UI elements properly initialized (hidden by default, shown during operations)
20 async unit tests cover success, cancellation, progress, and error paths

Changes Made

None required - implementation is complete

Status

Clean pass - no issues found

[REVIEWER] Review - Iteration 1

Summary

Thorough code review of all async operations implementation. Found 2 critical issues, 16 warnings, and 13 suggestions. Fixed the most impactful ones.

Findings

Critical: Re-entrancy bug in buttonCalculate_Click - double-click could race on _calculationCts
Critical: Resource leak - Dispose did not clean up _calculationCts or Watcher
Warning: Non-functional Cancel button during save operations (no CancellationToken passed)
Warning: Cross-thread UI access in LoadModelDataAsync after ConfigureAwait(false) in ReadAsync
Warning: Progress gap in ReadAsync - reported steps 1 and 3 of 3, skipping step 2
Warning: Empty error message in DisplayModelData when model fails to load
Noted (not fixed): Code duplication between sync/async methods (W4, W5), naming conventions on pre-existing code (S7, S8), timing-dependent progress tests (W21)

Changes Made

frmMain.cs:157 - Added re-entrancy guard (if (_calculationCts != null) return)
frmMain.Designer.cs:14-21 - Fixed Dispose to cancel/dispose _calculationCts and Watcher
frmMain.cs:715-746 - Save handler uses inline busy state instead of SetUIBusy (no Cancel button)
frmAddModel.cs:56 - Added .ConfigureAwait(true) to ensure UI thread for DisplayModelData
ModelReader.cs:132-163 - Fixed progress from 3 steps to 2 steps
frmAddModel.cs:79 - Added meaningful error message text

Status

Issues found and fixed
Build succeeds
All 77 tests pass

StreckerCM · 2026-02-05T18:14:57Z

[TESTER] Review - Iteration 2

Summary

Reviewed test suite for coverage gaps, test reliability, and edge cases. Fixed race condition in progress tests and added 6 new test cases.

Findings

Race condition: Progress<T> posts callbacks asynchronously via SynchronizationContext. Using Task.Delay(100) was a fragile workaround that could flake on CI.
Missing coverage: No tests for no-model-loaded error, out-of-range dates, unsupported extension via async, SaveResultsAsync cancellation, LoadAsync cancellation, or sync/async save parity.
Weak assertions: Progress tests only checked Count > 0 -- now verify exact step counts and monotonicity.

Changes Made

Added SynchronousProgress helper class implementing IProgress<T> directly (no race condition)
ReadAsync_ReportsProgress: Now verifies exactly 2 reports with correct step numbers and message
MagneticCalculationsAsync_ReportsProgress: Now verifies monotonically non-decreasing steps
New tests:
- MagneticCalculationsAsync_NoModelLoaded_ThrowsException
- MagneticCalculationsAsync_DateOutOfRange_ThrowsException
- ReadAsync_UnsupportedExtension_ThrowsModelNotLoaded
- SaveResultsAsync_CancelledToken_ThrowsOperationCancelled
- LoadAsync_CancelledToken_ThrowsOperationCancelled
- SaveResultsAsync_MatchesSyncSave (verifies identical output)

Status

Issues found and fixed
Build succeeds
83 tests pass (81 passed, 2 skipped for missing DAT files)

[UI_UX_DESIGNER] Review - Iteration 3

Summary

Reviewed async operations UI for usability, accessibility, visual feedback, and state consistency. Found 3 critical, 6 warning, and 7 suggestion-level issues.

Findings

C1 (Fixed): Escape key was always swallowed even with no calculation running, breaking standard Windows behavior
C2 (Fixed): Cancellation left grid in ambiguous empty state with no clear explanation
C3 (Noted): Save operation lacks progress bar and cancel support -- inconsistent with calculation flow (deferred: save is typically fast)
W1 (Noted): Single-date calculations cause progress bar to flash instantly (acceptable for MVP)
W2 (Partially fixed): Status resets to "Ready" after error; shows "Calculation cancelled - Ready" after cancel
W3 (Noted): Cancel button is text-only in status strip -- functional but low visibility
W4 (Noted): Menu bar stays enabled during calculation (deferred: no data corruption risk)
S1 (Fixed): Added AccessibleName to all StatusStrip controls
S2 (Fixed): Added ToolTipText with "(Esc)" hint to Cancel button

Changes Made

frmMain.cs:131 - Escape key only handled when _calculationCts != null
frmMain.cs:300-310 - Clear grid on cancel/error, reset status text to "Ready"
frmMain.Designer.cs:714 - Added AccessibleName = "Status" to status label
frmMain.Designer.cs:722 - Added AccessibleName = "Calculation progress" to progress bar
frmMain.Designer.cs:728-732 - Added AccessibleName and ToolTipText to Cancel button

Status

Critical issues fixed
Build succeeds
All 83 tests pass

Ralph Loop — Iteration 4 [SECURITY_AUDITOR]

Findings Summary

Severity	Count	Fixed
Critical	0	—
High	3	1
Medium	5	1
Low	4	0
Informational	5	0

High Severity

H1: TOCTOU in SaveResultsAsync — File validation (IsFileLocked, File.Exists, File.Delete) ran on calling thread while write executed in Task.Run, creating a race window. FIXED: Moved all file operations into the Task.Run block.
H2: File.AppendText on untrusted path — File.AppendText appends to existing files, which could corrupt output. FIXED: Replaced with File.WriteAllText for atomic creation.
H3: No path traversal validation on fileName — SaveResultsAsync and SaveResults accept arbitrary paths. Not fixed — the path comes from a SaveFileDialog which provides OS-level sandboxing, and the sync SaveResults has the same pattern. Low practical risk in a desktop app.

Medium Severity

M1: Exception info disclosure — e.ToString() in delete error exposed stack traces. FIXED: Pass as inner exception instead, so the message stays clean but inner exception is available for debugging.
M2-M5: CancellationTokenSource not thread-safe for concurrent Cancel/Dispose, Task.Run exceptions propagated raw, no file size validation, no timeout on file operations. Not fixed — all low practical risk for this desktop application (single UI thread cancels, exceptions are caught by UI handler, file operations are bounded by OS).

Low / Informational

File operations wrapped in Task.Run on .NET Framework use thread pool threads (acceptable)
No input sanitization for model file paths in ModelReader (uses FileDialog, not user text input)
ConfigureAwait(false) used correctly in library; ConfigureAwait(true) used correctly in UI code
Exception hierarchy follows established pattern with inner exception support

Changes

GeoMagSharp/GeoMag.cs: Moved file validation into Task.Run, replaced AppendText with WriteAllText, fixed info disclosure

Build & Test

✅ Build: Success
✅ Tests: 83 total (81 passed, 2 skipped)

StreckerCM · 2026-02-05T18:26:32Z

Ralph Loop — Iteration 5 [PROJECT_MANAGER]

Requirements Traceability — Issue #24

Acceptance Criteria	Status	Notes
`ModelReader.ReadAsync()` reads files without blocking UI	✅ Met	Wraps file I/O in Task.Run with progress and cancellation
`Calculator.SpotCalculationAsync()` off UI thread	✅ Met (design deviation)	Wrapped in Task.Run within MagneticCalculationsAsync rather than standalone method — avoids async-over-sync anti-pattern
`GeoMag.MagneticCalculationsAsync()` progress & cancellation	✅ Met	Per-date-step progress, cancellation at each iteration
Progress bar visible during operations	✅ Met	StatusStrip with ToolStripProgressBar
Cancel button stops operations	✅ Met	ToolStripButtonCancel with re-entrancy guard
Escape key cancels active operation	✅ Met	KeyDown handler, guarded to only fire during active calculation
Synchronous methods remain	✅ Met	All original sync methods preserved
All existing unit tests pass	✅ Met	83 total (81 pass, 2 skip for missing DAT files)
New async unit tests added	✅ Met	26 async-specific tests

Task Status

All 18 tasks in tasks.md: ✅ Complete
Build: ✅ Succeeds
Tests: ✅ 83 total (81 pass, 2 skip)

Changes

Updated docs/features/03-async-operations/tasks.md with correct test counts, Ralph Loop fixes section, design notes, and completion criteria checkmarks

Scope Check

No scope creep detected. All changes directly address issue Async Model Reader and Calculations #24 requirements.
Medium priority items from spec (LoadAsync, SaveAsync, SaveResultsAsync) all implemented.
One intentional design deviation (SpotCalculationAsync) is documented and technically superior.

Remaining: 2 clean cycles needed for completion criteria.

Ralph Loop — Iteration 6 [IMPLEMENTER] — Second Cycle

Verification

✅ Build: Success (0 errors, 0 warnings)
✅ Tests: 83 total (81 passed, 2 skipped)
✅ All async methods implemented and functional
✅ All sync methods preserved for backward compatibility

Status: CLEAN — No issues found.

StreckerCM · 2026-02-05T18:30:45Z

Ralph Loop — Iteration 7 [REVIEWER] — Second Cycle

Findings (3 actionable issues found and fixed)

#	Severity	File	Issue	Action
1	Warning	`frmMain.cs`	`saveToolStripMenuItem_Click` missing null check for `_MagCalculator`	Fixed: Added null guard
2	Warning	`frmMain.cs`	Save handler has no re-entrancy protection (rapid clicking)	Fixed: Added `_isSaving` flag and disabled save menu during save
3	Warning	`GeoMag.cs`	`SaveResultsAsync` accesses `_Models` and `_CalculationOptions` without null checks	Fixed: Added null guard before string building

Items reviewed but not actioned (pre-existing or by-design)

LoadModelDataAsync exists but is unused — by design (available for future callers when constructor pattern changes)
frmAddModel constructor error handling — pre-existing issue, not introduced by async changes
MagneticModelCollection.LoadAsync returns null on failure — mirrors sync Load behavior (pre-existing)
SetUIBusy doesn't disable model-loading menus — minor, models collection is not mutated during calc
Thread pool continuations after ConfigureAwait(false) — safe due to sequential loop execution

Changes

GeoMagGUI/frmMain.cs: Added _isSaving field, null guard, and save menu disable/enable
GeoMagSharp/GeoMag.cs: Added _Models/_CalculationOptions null check in SaveResultsAsync

Build & Test

✅ Build: Success
✅ Tests: 83 total (81 passed, 2 skipped)

Status: ISSUES FOUND AND FIXED — not a clean pass. Cycle 2 resets.

StreckerCM · 2026-02-05T18:31:16Z

Ralph Loop — Iteration 8 [TESTER] — Second Cycle

Test Coverage Review

26 async-specific tests covering all async methods
All critical paths tested: happy path, cancellation, error conditions, sync/async parity
SynchronousProgress helper eliminates timing-dependent test failures
Edge cases covered: null/empty inputs, non-existent files, unsupported extensions, no model loaded, date out of range

Test Results

✅ Build: Success
✅ Tests: 83 total (81 passed, 2 skipped for missing DAT files)

New defensive null guard in SaveResultsAsync

The _Models == null guard (added in Iteration 7) is unreachable through normal usage (ResultsOfCalculation is always null when _Models is null). Adding a test for this internal defensive check would require artificially manipulating private state. Not worth the added complexity.

Status: CLEAN — No issues found.

StreckerCM · 2026-02-05T18:32:00Z

Ralph Loop — Iteration 9 [UI_UX_DESIGNER] — Second Cycle

UI/UX Review

✅ StatusStrip: Properly positioned, label uses Spring for auto-sizing, left-aligned text
✅ Progress bar: Hidden by default, shown during calculation, reset to 0 on completion
✅ Cancel button: Hidden by default, visible during calculation, "(Esc)" tooltip
✅ Escape key: Guarded to only fire when _calculationCts != null
✅ Accessibility: AccessibleName set on all 3 StatusStrip controls
✅ Feedback: Status text updates through lifecycle (Calculating → Cancelled/Error/Complete → Ready)
✅ Grid: Cleared on cancel/error to prevent stale data display
✅ Re-entrancy: Calculate and Save both protected from concurrent invocations
✅ Cursor: Wait cursor shown during busy state

Status: CLEAN — No issues found.
