Cursor jumps to next line after running command same width as window. about terminal

[j4james]

This is a conpty issue - it doesn't occur in conhost/openconsole. What's meant to be happening is the cursor should move to the next line when you type a character on the last column of the page. Powershell actually makes a SetConsoleCursorPosition call to move it there - that just doesn't get translated correctly by conpty.

I think it may have to do with the vtengine's understanding of the WasWrapForced flag. We're using that to determine the lineWrapped state here:

terminal/src/renderer/base/renderer.cpp

Lines 746 to 751 in 67ae9f6

	// Calculate if two things are true:
	// 1. this row wrapped
	// 2. We're painting the last col of the row.
	// In that case, set lineWrapped=true for the _PaintBufferOutputHelper call.
	const auto lineWrapped = (buffer.GetRowByOffset(bufferLine.Origin().y).WasWrapForced()) &&
	(bufferLine.RightExclusive() == buffer.GetSize().Width());

Which in turn sets the _wrappedRow property here:

terminal/src/renderer/vt/paint.cpp

Lines 611 to 621 in 67ae9f6

	// GH#4415, GH#5181
	// If the renderer told us that this was a wrapped line, then mark
	// that we've wrapped this line. The next time we attempt to move the
	// cursor, if we're trying to move it to the start of the next line,
	// we'll remember that this line was wrapped, and not manually break the
	// line.
	if (lineWrapped)
	{
	_wrappedRow = coord.y;
	_trace.TraceSetWrapped(coord.y);
	}

Which concludes with us determining that the line was already wrapped by the text output, so there is no need to move the cursor.

terminal/src/renderer/vt/XtermEngine.cpp

Lines 260 to 266 in 67ae9f6

	// If the previous line wrapped, then the cursor is already at this
	// position, we just don't know it yet. Don't emit anything.
	auto previousLineWrapped = false;
	if (_wrappedRow.has_value())
	{
	previousLineWrapped = coord.y == _wrappedRow.value() + 1;
	}

But in this case the conpty client hasn't wrapped, because of the VT delayed wrap functionality, so we do need to emit something to force it onto the next line.

This problem can be fixed just by removing the above code, but I'm not sure if there are legitimate cases where we actually do need to avoid a cursor movement here. However, I think it's possible that this code may have been mistakenly introduced to compensate for the fact that the original Windows Terminal VT interpreter didn't handle delayed wrap correctly. Since that's been fixed, this may no longer be necessary. I'm not positive about that though.

@e82eric I forgot to add that the code you pointed out is also incorrect, and commenting it out will solve the problem in your particular case (i.e. when using powershell), but the underlying bug in the vtengine can still be triggered in other ways. For example, the cmd shell uses the legacy console API to write its output, and that doesn't pass through AdaptDispatch, but it does legitimately set the WasWrapForced flag, and will fail in a similar way.

@j4james thank you! that makes sense. Feel free to close this issue. (I had noticed it and wanted to see if I could sort out what was going on).

I tried commenting this out, and it did fix the issue, it does look like it has a side affect where when the window is resized the cursor moved and another line was added (I guess that is why those lines are needed).

terminal/src/renderer/vt/XtermEngine.cpp

Lines 260 to 266 in 67ae9f6

	// If the previous line wrapped, then the cursor is already at this
	// position, we just don't know it yet. Don't emit anything.
	auto previousLineWrapped = false;
	if (_wrappedRow.has_value())
	{
	previousLineWrapped = coord.y == _wrappedRow.value() + 1;
	}

I think it may be worth keeping this open, because there's definitely a bug here which is independent of issue #15602, and I don't think it's tracked anywhere else.

I haven't checked what exactly is going on there, but it's possible that's just a bug in the powershell readline implementation, and it only appears to be working correctly now because of the conpty bug.

[e82eric]

@j4james sounds good. I ran a time travel trace to see if I could find anything on why it did the weird jump with those lines commented out. It looked like it called Cursor::SetPosition twice. Once after Terminal::Reflow to x:12, y:5 and once from VirtualTerminal::StateMachine::ProcessString x:43 y:4 from .[m.[2;44H (I think windbg mangled the .[m. part).

Maybe a combination of Terminal::Reflow moving to line 3 and then something with PSReadLine moving it back to the correct line with a weird x offset.
