The nested dialog's `RunTimers()` calls see an **empty timeout queue** +6. Timeouts scheduled before the nested run never fire during the nested run + +### Why `now` is captured only once + +Additionally, `now = GetTimestampTicks()` is captured once at the start. If a callback takes a long time, `now` becomes stale, and the time evaluation `k < now` uses outdated information. + +## Impact + +This bug affects: + +1. **Example Demo Keys**: The `ExampleDemoKeyStrokesAttribute` feature doesn't work correctly when examples show MessageBox or dialogs. The ESC key to close dialogs is lost. + +2. **Any automated testing** that uses timeouts to simulate user input with modal dialogs + +3. **Application code** that schedules timeouts expecting them to fire during nested `Application.Run()` calls + +## Real-World Example + +The bug was discovered in `Examples/Example/Example.cs` which has this demo key sequence: + +```csharp +[assembly: ExampleDemoKeyStrokes( + KeyStrokes = ["a", "d", "m", "i", "n", "Tab", + "p", "a", "s", "s", "w", "o", "r", "d", + "Enter", // ? Opens MessageBox + "Esc"], // ? Should close MessageBox, but never fires + Order = 1)] +``` + +When "Enter" is pressed, it triggers: +```csharp +btnLogin.Accepting += (s, e) => +{ + if (userNameText.Text == "admin" && passwordText.Text == "password") + { + MessageBox.Query(App, "Logging In", "Login Successful", "Ok"); + // ? This blocks in a nested Application.Run() call + // The ESC timeout scheduled for 1600ms never fires + } +}; +``` + +## Solution + +Rewrite `TimedEvents.RunTimersImpl()` to process timeouts **one at a time** instead of batching them: + +```csharp +private void RunTimersImpl() +{ + long now = GetTimestampTicks(); + + // Process due timeouts one at a time, without blocking the entire queue + while (true) + { + Timeout? timeoutToExecute = null; + long scheduledTime = 0; + + // Find the next due timeout + lock (_timeoutsLockToken) + { + if (_timeouts.Count == 0) + { + break; // No more timeouts + } + + // Re-evaluate current time for each iteration + now = GetTimestampTicks(); + + // Check if the earliest timeout is due + scheduledTime = _timeouts.Keys[0]; + + if (scheduledTime >= now) + { + // Earliest timeout is not yet due, we're done + break; + } + + // This timeout is due - remove it from the queue + timeoutToExecute = _timeouts.Values[0]; + _timeouts.RemoveAt(0); + } + + // Execute the callback outside the lock + // This allows nested Run() calls to access the timeout queue + if (timeoutToExecute != null) + { + bool repeat = timeoutToExecute.Callback!(); + + if (repeat) + { + AddTimeout(timeoutToExecute.Span, timeoutToExecute); + } + } + } +} +``` + +### Key Changes + +1. **Lock ? Check ? Remove ? Unlock ? Execute** pattern +2. Only removes **one timeout at a time** that is currently due +3. Executes callbacks **outside the lock** +4. Future timeouts **remain in the queue**, accessible to nested `Run()` calls +5. **Re-evaluates current time** on each iteration to handle long-running callbacks + +## Verification + +The fix can be verified with these unit tests (all pass after fix): + +```csharp +[Fact] +public void Timeout_Fires_In_Nested_Run() +{ + // Tests that a timeout fires during a nested Application.Run() call +} + +[Fact] +public void Timeout_Scheduled_Before_Nested_Run_Fires_During_Nested_Run() +{ + // Reproduces the exact ESC key issue scenario +} + +[Fact] +public void Multiple_Timeouts_Fire_In_Correct_Order_With_Nested_Run() +{ + // Verifies timeout execution order with nested runs +} +``` + +See `Tests/UnitTestsParallelizable/Application/NestedRunTimeoutTests.cs` for complete test implementations. + +## Files Changed + +- `Terminal.Gui/App/Timeout/TimedEvents.cs` - Fixed `RunTimersImpl()` method +- `Tests/UnitTestsParallelizable/Application/NestedRunTimeoutTests.cs` - Added comprehensive tests + +## Additional Notes + +This is a **critical bug** for the Example infrastructure and any code that relies on timeouts working correctly with modal dialogs.
