🔬 App Profiling: CPU tracing, GC dumps, and trace visualization (#105) * feat: profiling wizard UI, integrated --dsrouter, and pipeline model - Refactor Profiling.razor from single scrolling form into 6-step wizard: Session Setup → Capture Kinds → Target → Review & Plan → Capture → Results - Add horizontal step indicator, Next/Back navigation, step validation - Move advanced session fields into collapsible section - Auto-run prerequisites and plan generation on entering Review step - Add placeholder steps for Capture Running and Results (pipeline runner TBD) - Update ProfilingCaptureOrchestrationService to prefer integrated --dsrouter: dotnet-trace/dotnet-gcdump now use --dsrouter android|android-emu|ios|ios-sim instead of separate dotnet-dsrouter process step - Add ProfilingStopTrigger enum and CanRunParallel/StopTrigger to step model - Set parallel/stop metadata on trace, launch, memory, and log steps - Keep CreateDsRouterStep as documented fallback - Update orchestration tests for new --dsrouter integrated commands - Verify no standalone dsrouter step in mobile plans - Assert CanRunParallel and StopTrigger on generated steps Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Change profiling artifact output dirs from GUIDs to project-name/date-run paths Replace opaque GUID-based output directories (artifacts/profiling/{guid}/) with human-readable paths (artifacts/profiling/{ProjectName}/{date}-{run}/). - Add BuildDefaultOutputDirectory method that derives the project name from the project path and auto-increments run numbers per date - Simplify artifact filenames: trace.nettrace, memory.gcdump, logs.txt - Update Profiling.razor placeholder text to reflect the new pattern - Add tests for output directory naming, artifact filenames, and fallback Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat: pipeline runner service, capture & results step UI - Add IProfilingSessionRunner interface with RunAsync, StopCapture, Cancel - Add ProfilingSessionRunnerService with dependency-ordered execution, parallel step support, long-running process management, SIGINT stop - Add ProfilingPipelineModels (state enums, step status, pipeline result) - Remove per-command 'Run in Sherpa' buttons from step 3 (Review & Plan) - Implement step 4 (Capture): live pipeline status, per-step cards with expandable output logs, Stop Capture and Cancel buttons - Implement step 5 (Results): artifact listing with file sizes, Reveal in Finder, Open in speedscope, Copy path, session summary, New Session - Register IProcessExecutionService as Transient (per-step instances) - Register IProfilingSessionRunner as Transient Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix: register IProfilingSessionRunner in macOS DI, change IProcessExecutionService to Transient Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix dsrouter conflict: use standalone dsrouter when both trace+gcdump on mobile When both dotnet-trace and dotnet-gcdump are requested on a mobile target, only one can use --dsrouter at a time. This change: - Detects when both trace and memory capture are requested on mobile - Falls back to a standalone dotnet-dsrouter process in that case - Both tools connect via --diagnostic-port using the IPC socket address - Introduces isMobileTarget flag to separate mobile detection from dsrouter arg - Fixes process discovery logic to not trigger for mobile targets - Adds test for trace-only mobile capture (still uses inline --dsrouter) - Updates existing mobile tests to expect standalone dsrouter behavior All 270 tests pass (223 Core + 47 Workloads). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix IPC socket path too long for macOS domain sockets macOS limits Unix domain socket paths to 104 characters. The previous naming pattern 'maui-sherpa-profile-{full-guid}.sock' was 108 chars when combined with the temp directory path, causing dsrouter and dotnet-trace to crash with ArgumentOutOfRangeException. Shortened to 'ms-prof-{8-char-guid}.sock' (~75 chars total). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix diagnostic-port to use connect mode for standalone dsrouter When using --diagnostic-port with a standalone dsrouter, both dotnet-trace and dotnet-gcdump must connect as clients (not create their own server). Append ',connect' to the IPC address so tools use connect mode instead of the default listen mode which tries to bind the same socket. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Set ANDROID_SERIAL env var for dsrouter device targeting When multiple Android devices/emulators are connected, adb commands (used by dsrouter for port forwarding) fail without knowing which device to target. Set ANDROID_SERIAL environment variable to the selected device identifier on all dsrouter-related steps (standalone dsrouter, dotnet-trace, dotnet-gcdump). Extracted BuildAndroidEnvironment() helper to set both ANDROID_HOME and ANDROID_SERIAL consistently across all Android profiling steps. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add auto-scroll to pipeline log output and fix app launch hang Auto-scroll: - Created logScrollInterop.js with track/scrollToBottom/untrack methods - Log containers auto-scroll to bottom as output arrives - Pauses auto-scroll when user scrolls up manually - Re-engages when user scrolls back to bottom - Tracks per-container via element ID App launch fix: - Changed SuspendAtStartup default from true to false - Prevents profiled apps from hanging on splash screen waiting for diagnostic tool connection (the previous default suspended the runtime) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix stop capture to cleanly shut down and show results When user clicks Stop Capture, all running steps should be treated as 'stopped' (not failed), artifacts should be collected, and the pipeline should transition to Completed with results. Changes: - Added _stopRequested flag to ProfilingSessionRunnerService - StopCapture() now marks ALL running steps as Stopped (not just ManualStop ones) since killing dsrouter cascades to dependent steps - LaunchStepAsync treats non-zero exits as 'stopped' when _stopRequested - RunAsync catch block detects stop-during-shutdown and collects artifacts instead of reporting failure - Pipeline transitions to Completed (with partial results) after stop Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Convert profiling sample to native MAUI with Blazor fallback - Create NativeMainPage.cs with full native MAUI controls for all 4 scenarios (CPU stress, memory allocation/churn, rendering tile wall + feed, network bursts) - Add RunNativeNetworkBurstAsync to ProfilingScenarioService (HttpClient-based, replaces JS fetch for native mode) - Fix BlazorMainPage constructor name (was still MainPage after rename) - Native page includes: metrics strip (6 process/GC labels), scenario cards with sliders/buttons/status labels, tile wall with FlexLayout, feed list, network results list - App defaults to native page with toolbar button to switch to Blazor view - Dark theme styling matching Blazor version Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix artifact discovery: remove speedscope format, fix path nesting - Remove --format speedscope from dotnet-trace args — it caused the output file to be written as trace.nettrace.speedscope.json while we looked for trace.nettrace. Raw .nettrace is the most useful format anyway. - Fix CollectArtifacts double path nesting — RelativePath already contains the full path from CWD (including OutputDirectory), but the old code prepended OutputDirectory again, making files unfindable. - Use Path.GetFullPath for consistent absolute path resolution. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix artifact paths and add per-step log files - Make OutputDirectory absolute at plan creation time by resolving relative paths against the project's working directory. The macOS app runs from inside the .app bundle, so relative paths resolved to the wrong location when checking for artifacts. - Write per-step stdout/stderr to {stepId}.log files in the output directory. Each log includes a header (command, timestamp) and footer (exit code, duration, errors). Logs stream in real-time via AutoFlush. - Update test to expect absolute output directory path. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix artifact flush: wait for process exit after SIGINT dotnet-trace needs time to finalize the .nettrace file after receiving SIGINT. Previously, Cancel() sent SIGINT then immediately cancelled the linked CancellationTokenSource, which caused WaitForExitAsync to throw and return before the process had flushed its output. Now Cancel() sends SIGINT and waits up to 15s for the process to exit before cancelling the token, giving tools time to write their output files. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix process shutdown: let SIGINT'd processes exit naturally The core issue: Cancel() sent SIGINT then immediately cancelled the CancellationToken, which unblocked WaitForExitAsync before the process had time to flush output files (dotnet-trace needs several seconds to finalize .nettrace). Now Cancel() sends SIGINT but does NOT cancel the token — WaitForExitAsync naturally completes when the process exits after flushing. A 30s safety timeout force-cancels only if the process hangs. Also made StopCapture async (StopCaptureAsync) on the interface. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix Android profiling: use AndroidEnableProfiler and adb setprop Replace incorrect MSBuild properties (DiagnosticAddress, DiagnosticPort, DiagnosticListenMode, EnableDiagnostics) with the correct Android profiling setup: - Use AndroidEnableProfiler=true to include Mono diagnostic component - Add adb shell setprop debug.mono.profile step to configure diagnostic port - Add adb reverse step for physical Android devices - Set ANDROID_SERIAL environment on launch step for multi-device targeting The runtime diagnostic port on Android is configured via the debug.mono.profile system property, not MSBuild properties. This was confirmed by testing against the dotnet/android documentation and verified with successful trace captures. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix Stop Capture button visibility during active recording The Stop Capture button was only shown during the 'Running' state (while steps are launching) but hidden during 'WaitingForStop' (when capture tools are actively recording and waiting for user to stop). This meant the user could only see a Cancel button during recording. Fix: Show Stop Capture button during WaitingForStop (the active recording state) and show a launching spinner during Running. Also show elapsed time during WaitingForStop and update state text to clarify what each state means. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add profiling results visualization: speedscope viewer, GC dump table, auto-conversion - Bundle speedscope v1.25.0 standalone build in wwwroot/speedscope/ - Add JS interop (speedscopeInterop.js) to load profile data into iframe - Add inline speedscope viewer in Results step with auto file injection - Create GcDumpReportParser (Core) to parse dotnet-gcdump report output - Create GcDumpReportService to shell out to dotnet-gcdump and return data - Create ProfilingArtifactConverterService for .nettrace to .speedscope.json - Pipeline runner auto-converts .nettrace to speedscope after capture - Results step shows 'View Trace' and 'View GC Dump' action buttons - GC dump viewer: sortable/filterable table with type, count, size, % bar - Add IGcDumpReportService and IProfilingArtifactConverterService interfaces - Register new services in both MauiProgram.cs and MacOSMauiProgram.cs - Add 6 unit tests for GcDumpReportParser (229 total, all passing) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add profiling session library: persistent sessions, session list UI, import/export - Add ProfilingSessionManifest models for persistent session metadata - Add ProfilingSessionStorageService for CRUD + import/export of session folders - Transform Profiling page from one-shot wizard to session library with ViewMode toggle - Session list shows cards with platform icon, date, duration, artifacts, status badges - Expandable session cards with inline artifact viewers (speedscope, GC dump) - Session persistence: captures auto-save session.json with full manifest after pipeline - Output directory now uses managed storage (AppDataPath/profiling/{session-id}/) - Toolbar: New Session (+), Import, Search, Refresh buttons - Session actions: Export (.zip), Open Folder, Delete with confirmation - Empty state with prominent 'New Profiling Session' call-to-action - Wizard mode accessible via 'Back to Sessions' navigation Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Extract profiling wizard steps 0-4 into modal dialog Move the inline wizard (steps 0-4: Session Setup, Capture Kinds, Target, Review & Plan, Capture) from Profiling.razor into a new ProfilingCaptureWizardModal.razor component that uses the established WizardFormPage pattern for native footer buttons (Back/Next/Start Capture). - Create ProfilingCaptureWizardModal.razor at /modal/profiling-wizard route - Wire HybridFormBridge for native Back/Next/Submit button control - Handle pipeline completion: save session manifest, set bridge.Result - Hard link already exists for macOS project - Simplify Profiling.razor to session list only (remove ViewMode enum) - Add StartNewWizardAsync using IFormModalService.ShowAsync pattern - Auto-expand new session in list after wizard completes Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix stray closing brace rendered on profiling session list page Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix 10 profiling UI polish issues - Fix GC dump timing: add build-and-run dependency so gcdump waits for app - Fix nettrace viewer: handle conversion failure with inline error + retry - Fix artifact card layout: buttons wrap to their own row - Reduce wizard modal padding for compact layout - Add squircle border-radius (14px) on all cards/panels - Fix artifact path overflow: show filename only, full path in tooltip - Make plan step commands collapsible (collapsed by default) - Disable Next button during prerequisites check and plan generation - Simplify prerequisites: green banner when all pass, expandable details - Fix suspend at startup: default to false, add descriptive help text Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Split artifacts into profiling and log file sections Profiling artifacts (.nettrace, .gcdump, .speedscope.json) show in a primary always-visible section. Log files (.log) are grouped into a collapsible section that starts collapsed, keeping the view clean. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Reorganize wizard: move Scenario & Suspend to Capture Kinds step - Move Scenario dropdown from Step 0 to Step 1 (Capture Kinds) as preset - Move Suspend at Startup from Step 0 Advanced to Step 1 - Auto-toggle suspend when Launch scenario selected - Rename Step 0 from 'Session Setup' to 'Project' - Reduce outer padding from 0.5rem to 0.25rem Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Remove inline New Profiling Session button and reduce wizard padding Toolbar + button already provides the CTA. Also eliminates remaining excess padding in the wizard step indicator and form-content wrapper. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Remove scenario summary from Target step Already shown on Capture Kinds step; no need to repeat on Target. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Polish wizard: compact prerequisites, plan summary, and commands - Auto-toggle suspend at startup when Startup capture kind is checked - Remove platform notes info-banner from Target step - Prerequisites: use FA icon instead of emoji, compact list with inline status icons instead of verbose grid cards - Plan summary: inline key-value rows instead of 4 nested cards - Commands: compact list with tooltip descriptions instead of card grid - Move Expected Artifacts before Commands in capture plan - Clean up unused CSS (prereq cards, summary cards, command cards) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Simplify expected artifacts to flat inline list Replace grid of nested cards with a compact row-per-artifact layout showing name, filename, and kind inline. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Show managed session storage path in plan preview Plan preview now pre-computes the session storage directory path instead of showing the relative artifacts/ path. The actual pipeline still generates its own session ID at start time. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Wrap output directory path on its own line in capture plan Long paths no longer cause horizontal scrolling. The path is now in a wrapping monospace code block below the label. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Flatten nested panel cards across all wizard steps Replace

wrappers with flat step-content/section-header pattern across Steps 0-4. Add CSS for .step-content, .section-header, and .section-title classes. Remove extra closing div tag from capture plan step. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix input/select background to contrast with dialog Change field-group inputs and selects from --bg-primary to --bg-secondary so they visually stand out from the dialog background. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix section header background and remove unused panel CSS Set explicit transparent background on section-header to prevent subtle color artifacts on hover. Remove dead .panel/.panel-header/ .panel-body CSS no longer used after card flattening. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Show section headers with inline loading on Review & Plan step Replace single loading spinner with always-visible Prerequisites and Capture plan section headers. Each shows inline status badges (Checking.../Generating.../Waiting...) while loading, then expands content when ready. Add .section-loading CSS. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Hide section header badges while loading Only show status badges (All OK, Valid, etc.) after loading completes. The inline loading text below the header is sufficient during loading. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Simplify prerequisites to chips + chevron toggle Remove success banner card. Show status badges inline in section header with a chevron button to expand/collapse details. Move loading indicators to inline text in headers for both Prerequisites and Capture plan. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Redesign capture plan: squircle card, artifact chips, unified command list - Wrap TFM and output directory in a borderless squircle card - Show expected artifacts as inline extension chips (.nettrace, .gcdump) next to output directory label instead of separate section - Replace individual command cards with a single bordered list using border-bottom separators and chevron toggle on far right - Remove unused expected-artifact and command-details CSS Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Stop duplicating prerequisite warnings in capture plan Prerequisite warnings (like 'Update available') are already shown in the Prerequisites section. Remove forwarding them into plan validation warnings to avoid redundant display. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Reduce input/select and Browse button sizing in wizard Decrease field padding and font-size for a more compact, consistent look. Make Browse button match input height with smaller padding. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Move Stop Capture and Cancel to native footer buttons On step 4, the native primary button becomes 'Stop Capture' when the pipeline is waiting for stop. The native Cancel button cancels the pipeline and returns to step 3 without closing the modal (via new PreventClose bridge property). Remove redundant Blazor action buttons. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix trace files going to wrong directory Pass session storage path as OutputDirectory when generating the plan so commands and artifact RelativePaths are built with the correct path. Previously the plan was generated with a relative artifacts/ path and only the top-level OutputDirectory was overridden at pipeline start, leaving command arguments pointing to the old location. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Compact artifact list: rows with inline actions Replace large artifact cards with a compact bordered list. Each artifact is a single row with icon, filename, size, and small action buttons on the right. View buttons stay labeled; Reveal/Copy are icon-only with tooltips. Error rows nest below the relevant artifact. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix Stop Capture closing modal before session is saved The native Submit button (renamed to 'Stop Capture') always closed the modal after the handler returned. But HandleStopCapture just signals the pipeline to stop — the actual completion, artifact collection, and session saving happen asynchronously in StartPipelineAsync. Add PreventSubmitClose to HybridFormBridge so the native Submit handler does not pop the bridge and close the modal while the pipeline is still active. After the pipeline completes and the session is saved, the Blazor component calls bridge.RequestClose() to close the modal with the manifest as the result. Also adds CloseRequested event to HybridFormBridge for Blazor components to programmatically close the modal with a result. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix GC dump running before app is ready The pipeline executor treated a long-running dependency as satisfied the moment it started. This was fine for dotnet-trace (which itself waits for the app to connect via the diagnostic port) but broke dotnet-gcdump, which connects, collects, and exits immediately — before the app had even finished building. Changes: - Add IsReady property to ProfilingStepStatus. Long-running steps signal readiness when their output matches a configurable ReadyOutputPattern. - Add ReadyOutputPattern to ProfilingCommandStep. Set to 'Process' for dotnet-trace (emitted when the app connects) and 'Build succeeded' for the build-and-run step. - Refine dependency logic: non-long-running steps (like gcdump) now wait for their long-running dependencies to signal IsReady, not just start. Long-running steps still proceed as soon as the dependency starts. - Make capture-memory depend on capture-trace when both are requested, so gcdump waits for trace to establish its diagnostic port connection. - Poll with 500ms delay when waiting for readiness instead of blocking on task completion only. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Open artifact viewers in separate windows Move speedscope and GC dump viewers from inline rendering on the Profiling page to dedicated Blazor pages (SpeedscopeViewer.razor, GcDumpViewer.razor) that open in their own macOS windows via ProfilingViewerService. Each viewer type gets its own window; clicking View again replaces the previous viewer window. Removes ~200 lines of inline viewer HTML, CSS, and state management from Profiling.razor. The viewer pages are self-contained with their own loading, error, and content states. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix GC dump deadlock: add ReadyOutputPattern to dsrouter step The start-dsrouter step was long-running but had no ReadyOutputPattern, so its IsReady flag was never set. Since capture-memory (GC dump) is a non-long-running step that depends on dsrouter, IsDependencySatisfied required IsReady == true — causing a permanent deadlock. dsrouter outputs 'Starting IPC server' when ready; use that as the readiness pattern. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Make GC dump on-demand instead of automatic pipeline step dotnet-gcdump is a point-in-time heap snapshot, not a continuous collector. Running it automatically in the pipeline captured the heap at an arbitrary moment (usually right after app launch, before anything useful happens). Now GC dump is triggered on-demand via a 'Collect GC Dump' button in the capture step UI. Users can take multiple snapshots at specific moments during their session. Each dump is numbered (memory-1.gcdump, memory-2.gcdump, etc.) and tracked as a session artifact. Changes: - Remove capture-memory from automatic pipeline commands - Add CollectGcDumpAsync() to IProfilingSessionRunner for on-demand use - Add Collect GC Dump button in wizard capture step (visible when pipeline is in WaitingForStop state and memory capture is selected) - Update tests to reflect GC dump is no longer an auto pipeline step Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add macOS AppKit implementation for ShowInputDialogAsync The DialogService.ShowInputDialogAsync was wrapped in #if MACCATALYST and the #else branch returned null, so the keystore password prompt never appeared on macOS AppKit builds. Add a MACOSAPP implementation using NSAlert with an accessory NSTextField (NSSecureTextField for password prompts). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix cloud keystore deletion silently failing DeleteKeystoreFromCloudAsync was ignoring the bool return values from DeleteSecretAsync, so when Infisical delete calls failed, the UI showed a success toast and optimistically removed the item. On refresh, the keystore reappeared because it was never actually deleted. Now checks return values and throws InvalidOperationException with details on which secrets failed to delete. Also improved Infisical error logging to include inner exception messages for debugging. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix cloud keystore delete using wrong alias for names with underscores ExtractAliasFromKey strips the last _segment assuming it's the suffix (_JKS/_PWD/_META). But DeleteFromCloud passed 'KEYSTORE_{alias}' with no suffix, so for aliases like TEST_SIGNING_KEY it extracted TEST_SIGNING instead — deleting non-existent keys while the real ones remained. Fix: pass the alias directly to DeleteKeystoreFromCloudAsync instead of wrapping it in KEYSTORE_ prefix and re-extracting. Also filter Infisical ListSecrets to exclude imported secrets from other paths. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Enable MauiDevFlow profiling in sample app Configure EnableProfiler, EnableHighLevelUiHooks, and EnableDetailedUiHooks in the profiling sample app. Update MauiDevFlow packages from 0.18.0 to 0.20.0. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Require MauiDevFlow 0.20.0 for profiling, show version message Update all MauiDevFlow package references from 0.18.0 to 0.20.0. Add minimum version check (0.20.0) to the DevFlow profiling tab — shows a clear message when the connected agent is too old instead of failing with a capabilities error. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix dotnet-trace to capture useful CPU sampling data for speedscope dotnet-trace collect was invoked without --profile or --providers, producing nearly empty speedscope files (9 generic frames, no managed stacks). Now maps ProfilingCaptureKind to dotnet-trace profiles: - Cpu/Startup → cpu-sampling (~100Hz kernel sampling) - Rendering/Network/Energy/SystemTrace → dotnet-common Also adds --format Speedscope so dotnet-trace emits both .nettrace and .speedscope.json during capture, eliminating the separate post-capture conversion step. Converter kept as fallback for manually imported .nettrace files. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix dotnet-trace profile: use dotnet-sampled-thread-time (cross-platform) cpu-sampling is Linux-only (collect-linux). Use dotnet-sampled-thread-time which works on all platforms and samples managed stacks at ~100Hz. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Remove --format Speedscope from dotnet-trace collect The --format flag may cause issues with --dsrouter mode, causing the trace to end prematurely. Keep using post-capture conversion via dotnet-trace convert instead. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Make trace on-demand with Start/Stop buttons alongside GC Dump - Remove capture-trace from auto-planned pipeline steps - Add StartTraceAsync/StopTraceAsync to IProfilingSessionRunner - Add IsTraceActive property for mutual exclusion with gcdump - Pipeline enters WaitingForStop for on-demand actions even without ManualStop steps - Always use standalone dsrouter on mobile (needed for on-demand trace/gcdump) - Add JIT/Loader provider flags (Microsoft-Windows-DotNETRuntime:0x10000018:5) for speedscope symbol resolution - Unified capture action bar UI with Start Trace, Stop Trace, and GC Dump buttons - Disable conflicting actions (no gcdump while tracing, no trace while gcdump) - Stop active trace automatically when user clicks Stop Capture - Update 4 orchestration tests for on-demand trace pattern Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix session artifacts, speedscope loading, and nettrace View button - Scan output directory for on-demand gcdump/nettrace/speedscope files not in the expected artifact list (memory-1.gcdump, trace-1.nettrace, etc.) - Add fallback directory scan in wizard manifest creation for all artifact types - Fix speedscope iframe to use #localProfilePath=1 hash param so window.speedscope.loadFileFromBase64() API is available - Add polling (up to 5s) for speedscope API initialization with drop fallback - Hide .nettrace View button on macOS (redundant with .speedscope.json; only useful on Windows with PerfView) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix speedscope and gcdump viewer content loading Speedscope: Replace cross-frame contentWindow API injection (fails in WKWebView) with postMessage. Add message listener script to bundled speedscope/index.html that receives profile data and simulates file drop within iframe's own JS context. Remove broken #localProfilePath=1 hash that injected failing
