v0.12.3

?safeshinytab=track shows the monitoring tab and starts tracking automatically (#34, #35). New exported SafeShinyTrackRequested(); SafeShinyTabServer() gains a param argument.

v0.12.2

Docs: precise kill-switch semantics, production vs test section in the vignette (#30, PR #31). SafeObserveEvent records every event phase while tracking (#32, PR #33).

v0.11.2

SafeObserveEvent now also protects the event expression (an error in e.g. a throwing event reactive no longer closes the session) and tracks its evaluation as ' (event)' (nested reactives; recorded only when non-trivial). See #26.

v0.11.1

trimMinTime now defaults to 0 (every call counts when trimming); use e.g. 0.01 to ignore tiny tab-switch observers. See #24.

v0.11.0

Trim: new trimMinTime argument (default 0.01 s) - tiny calls such as tab-shown observers no longer set the edges of the trimmed window; calls outside it are dropped from the trimmed chart/summary. See #22.

v0.10.1

Console sub-tab: fixes a session crash on non-UTF-8 output (shown as escapes), reads only the log tail, fails soft. See #20.

v0.10.0

Monitoring tab: new height argument for SafeShinyTabUI()/SafeShinyTabPanel() (percentages = share of viewport height). See #18.

v0.9.0

Monitoring tab: scrollable sub-tabs, stale tables fixed (incl. error log Refresh), trim option for SummarizeSafeShinyTiming()/PlotSafeShinyFlameHTML(), opt-in Console sub-tab (view, clear, download). See #16.

SafeShiny v0.8.0

New

• Session-level tracking switch: StartSafeShinyTracking() / StopSafeShinyTracking() / IsSafeShinyTracking(). trackTime now defaults to "auto": tracked while options(SafeShiny.trackTime = TRUE) is set or the session's tracking is on, decided each time the call runs (covers wrappers created by other packages; never affects other sessions).
• options(SafeShiny.trackTime = FALSE) is a static master kill switch (IsSafeShinyTrackingDisabled()), resolved once when each wrapper is created.
• Error log: GetSafeShinyErrors() / ResetSafeShinyErrors() record every non-silent error caught by a Safe* wrapper (last 500 per session). Per-session state is freed when the session ends.
• Monitoring module: SafeShinyTabUI() / SafeShinyTabServer() / SafeShinyTabPanel() - Start/Stop button, interactive flame chart, timing summary/table, error log, downloads; SafeShinyTabRequested() gates it via ?safeshinytab=1.

Performance

• Recording a timing is O(1) (was quadratic in the number of recorded calls).
