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: extract outputFormatter collaborator from eventLoopPaul Buetow
The printCb and warningCb function fields on eventLoop bundled two distinct concerns (pair emission and warning delivery) directly on the event-processing struct. This commit extracts them into a dedicated outputFormatter type that owns these callbacks plus emit() and notifyWarning() helper methods. outputFormatter is embedded (not pointed-to) in eventLoop so that existing call sites — including tests that write el.printCb = ... and el.warningCb = ... directly — require no changes beyond the three struct-literal sites in eventloop_filter_test.go that used field initialiser syntax. fdTracker and commResolver were already proper collaborator types; only the output concern needed extraction.

2026-05-13feat(eventloop): add panic recovery to events() goroutine for resiliencePaul Buetow
Wrap processRawEvent calls in a new processRawEventSafe() helper that uses defer/recover to catch any panic from a callback and convert it into a warning notification via warningCb, preventing a single bad event from crashing the whole process. Added TestEventsPanicInCallbackIsRecoveredAndNotified to verify the recovery behaviour end-to-end. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-05-08swap global filter in place to skip BPF reattachPaul Buetow
Changing the global filter used to call stopTrace + beginTraceCmd, which detached and re-attached every tracepoint and re-loaded the BPF object. On heavily loaded I/O systems that took several seconds and showed an 'Attaching tracepoints...' overlay each time. The probe set never depends on the global filter (ShouldIAttachTracepoint only reads CLI regex flags), so the restart was gratuitous. Now the eventloop holds its filter behind atomic.Pointer with SetFilter / Filter accessors, and the trace starter registers el.SetFilter via the runtime bindings as a SetLiveFilterSetter callback. applyGlobalFilter and undoGlobalFilter call runtime.applyLiveFilter first; only if no trace is running do they fall back to the full restart path.
2026-03-18refactor: extract pairTracker and extend fdTracker to reduce eventLoop ↵Paul Buetow
responsibilities (task 428) The eventLoop struct held 20+ fields across 5+ responsibilities (SRP violation). Extract two cohesive sub-structs: - pairTracker: enter/exit pair matching, age-based LRU pruning, and DurationToPrev tracking. Replaces enterEvs/enterEvAges/prevPairTimes/ maxPendingEnterEvs/cacheAge fields with a single embedded value. - fdTracker (extended): absorbs procFdCache/procFdAges/maxProcFdCacheSize, moving all procfs-resolution cache logic (resolve, cache, prune, delete) off eventLoop and onto the tracker that already owns the fd table. eventLoop drops from 20 fields to 12. All methods that previously reached into eventLoop fields now live on the struct that owns the data. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
