From 01825dea321e8d7158477cef1b9e49ca1a577fe4 Mon Sep 17 00:00:00 2001 From: Shane Neuville Date: Sun, 29 Mar 2026 11:49:27 -0500 Subject: [PATCH 1/6] feat: scheduled tasks (cron jobs) for recurring prompt execution MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a cron-like scheduled tasks system for recurring prompt execution — daily stand-ups, periodic reviews, automated checks, etc. ## Features - Three schedule types: Interval (every N minutes), Daily (at time), Weekly (days + time) - Cron expression support: 5-field (min hour dom month dow) with wildcards, ranges, lists, and step values (e.g., '0 9 * * 1-5' for weekdays at 9am) - Full CRUD UI page at /scheduled-tasks with form validation - Task cards with toggle, edit, run-now, delete (with confirmation), and history - Expandable run history showing last 10 executions with timestamps and error details - Background timer evaluates due tasks every 30 seconds with overlap guard - Executes by sending prompt to existing session or creating a new one per run - Persists to ~/.polypilot/scheduled-tasks.json - Test isolation via SetTasksFilePathForTesting wired into TestSetup.cs ## Bug Fixes (from original Copilot bot PR) - Fix Interval snap-forward: missed intervals return the last boundary, not 'now' - Fix Daily schedule: consistent local-time date comparison instead of mixed UTC/local - Fix SaveTasks race: RecordRunAndSave now holds lock through save - Fix CSS font-family enforcement: use var(--font-mono) not raw monospace - Fix .NET 10 Blazor type inference: use text input for time-of-day instead of type=time ## Tests (71 total) - Model: serialization, schedule descriptions, time parsing, due detection - Cron: valid/invalid expressions, ranges, steps, lists, JsonRoundTrip, next-run - Validation: IsValidTimeOfDay, ScheduleType.Cron enum, max interval - Schedule edge cases: daily never-run, daily already-ran-today, interval snap-forward - Service: persistence, CRUD, execution, error handling, corrupt file handling Fixes PureWeen/PolyPilot#367 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- PolyPilot.Tests/PolyPilot.Tests.csproj | 2 + PolyPilot.Tests/ScheduledTaskTests.cs | 755 ++++++++++++++++++ PolyPilot.Tests/TestSetup.cs | 1 + .../Components/Layout/SessionSidebar.razor | 1 + .../Components/Pages/ScheduledTasks.razor | 446 +++++++++++ .../Components/Pages/ScheduledTasks.razor.css | 513 ++++++++++++ PolyPilot/MauiProgram.cs | 1 + PolyPilot/Models/ScheduledTask.cs | 315 ++++++++ PolyPilot/Services/ScheduledTaskService.cs | 303 +++++++ 9 files changed, 2337 insertions(+) create mode 100644 PolyPilot.Tests/ScheduledTaskTests.cs create mode 100644 PolyPilot/Components/Pages/ScheduledTasks.razor create mode 100644 PolyPilot/Components/Pages/ScheduledTasks.razor.css create mode 100644 PolyPilot/Models/ScheduledTask.cs create mode 100644 PolyPilot/Services/ScheduledTaskService.cs diff --git a/PolyPilot.Tests/PolyPilot.Tests.csproj b/PolyPilot.Tests/PolyPilot.Tests.csproj index 43c8f833f..9c2a6af6f 100644 --- a/PolyPilot.Tests/PolyPilot.Tests.csproj +++ b/PolyPilot.Tests/PolyPilot.Tests.csproj @@ -96,6 +96,8 @@ + + diff --git a/PolyPilot.Tests/ScheduledTaskTests.cs b/PolyPilot.Tests/ScheduledTaskTests.cs new file mode 100644 index 000000000..bb9ec2959 --- /dev/null +++ b/PolyPilot.Tests/ScheduledTaskTests.cs @@ -0,0 +1,755 @@ +using System.Text.Json;

Service eager start — ScheduledTaskService now resolved eagerly in MauiProgram.cs so the background timer starts on app launch, not just when the user visits the Scheduled Tasks page. 2. Cron off-by-one — GetNextCronTimeUtc now starts from the current minute (not +1). LastRunAt prevents re-firing within the same minute. 3. Weekly missed-day — Weekly schedule now mirrors Daily logic: only skips today's passed slot if LastRunAt shows the task already ran today. 4. Edit preserves run history — UpdateTask now merges only user-editable fields onto the canonical instance. LastRunAt and RecentRuns are never overwritten by stale clones from the edit form. 🟡 MODERATE fixes: 5. Atomic file write — SaveTasks uses write-to-temp + File.Move to prevent data loss on crash during write. 6. I/O outside lock — SaveTasks snapshots tasks under lock, then does serialization and file I/O outside the lock to prevent UI freezes. Additional hardening: - Start() checks _disposed guard to prevent zombie timers after Dispose - Per-task exception isolation in EvaluateTasksAsync foreach loop - Fixed 5 flaky timing tests in TurnEndFallbackTests using TCS pattern - Fixed minute-boundary race in CronSchedule_IsDue_ReturnsFalseWhenAlreadyRanThisMinute - Added tests: UpdateTask preserves run history, atomic write verification, Start-after-Dispose guard All 3,088 tests pass (0 failures).
