2026-05-23Merge branch 'main' into developPaul Buetow
2026-05-230c promote aggregate-only sampling defaults in raw output modesPaul Buetow
Default aggregate-only sampling (rate 0) for futex* and clock_gettime causes BPF to suppress ring-buffer events. In -plain, -flamegraph, and headless -parquet modes there is no aggregate sink, so these probes would emit no rows even when explicitly selected. Promote those defaults to rate 1 during flag resolution; user-explicit overrides are preserved. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

2026-05-13add TUIFastRefreshInterval flag to flags.ConfigPaul Buetow
Add TUIFastRefreshInterval time.Duration to flags.Config struct with a default of 250ms and register it as the -tui-fast-refresh CLI flag so callers can tune or disable the high-frequency TUI refresh cadence for the flamegraph and stream tabs.

2026-05-13refactor: break down functions exceeding 50 lines into smaller helpersPaul Buetow
Split 22 production files across the codebase — event loop, TUI models, probe manager, dashboard, export, flag parsing, code generation, and ioworkload scenarios — so that no function body exceeds 50 lines. Each extracted helper carries its own comment explaining its role. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-05-13refactor: move TraceFilter and tracepoint selector logic out of flags.ConfigPaul Buetow
- Add tracepoints.Selector type with ShouldAttach method and ParseSelector constructor, replacing the raw TracepointsToAttach/TracepointsToExclude regex slices on flags.Config. - Add flags.BuildTraceFilter as a standalone function replacing the Config.TraceFilter() method, keeping filter-building logic out of the config struct. - Remove stale ShouldIAttachTracepoint noise-filter entry from Magefile. - Add selector_test.go with full coverage of ParseSelector and ShouldAttach.

2026-05-13fix: reject negative and zero -duration flag values with a clear errorPaul Buetow
A negative or zero -duration was silently accepted, causing the trace context to be cancelled immediately (time.Duration(N) * time.Second with N <= 0 yields a non-positive timeout), so no events were ever captured. parseFromFlagSet now returns an error for Duration <= 0, matching the existing pattern used for -resetTimer validation. Three new tests cover the negative, zero, and valid positive cases. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-05-13replace global flags singleton with Parse() returning Config valuePaul Buetow
Remove the global atomic.Pointer[Config], sync.Once, and parseErr fields from the flags package. Parse() now returns (Config, error) directly, eliminating all global-state accessors (Get, SetPidFilter, SetTidFilter, SetTUIExportEnable, setCurrent, updateCurrent). The internal parse logic is factored into parseFromFlagSet so tests can inject a fresh FlagSet without touching os.Args or package-level state.

2026-05-12rename ShouldIAttachTracepoint receiver from flags to fPaul Buetow
The receiver name flags shadowed the package name flags, making the package inaccessible inside the method body. Rename to f to match all other receivers in flags.go and add a doc comment. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-05-12add Go doc comments to exported fields on flags.Config and globalfilter.FilterPaul Buetow
Document every exported field in Config (flags package) and Filter, NumericFilter, StringFilter (globalfilter package) with a concise one-line doc comment describing its purpose and behaviour. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-05-09add auto-reset timer for dashboard aggregatesPaul Buetow
Live flamegraph trie and stats engine grow unboundedly during long traces. Add a periodic auto-reset (same effect as the 'r' key) so they stay bounded. - New CLI flag -resetTimer=30s (default 30s, 0 disables). - Hotkey I cycles the cadence: off -> 15s -> 30s -> 60s -> 5m -> off. Custom intervals (e.g. -resetTimer=47s) advance to the first preset greater than the current value, then wrap to off. - autoResetTickMsg carries a generation counter so changing the cadence drops in-flight ticks scheduled under the previous interval. - Dashboard chrome shows 'auto-reset: 30s' or 'auto-reset: off'.
