I noticed firefox debugger requires multiple step-out-presses to step out of a function. Turns out Firefox has an intermediate step to show the return value. I found this confusing, thought that the extra step was a bug. Chrome behaved as I expected.

This is by design, so that the user will have a chance to observe the returned (or thrown) value which is often ignored.

Pref?

Right, and I agree that this is a good bit of info to show the user, but I think we can improve the UI/UX so that it doesn't appear that step out is broken *and* we still present the return/exception/yeild to the user. I don't have any solid ideas for what this might look like yet, but I think it can be done.

This wouldn't happen to be related to bug 1052738, would it?

(In reply to Eddy Bruel [:ejpbruel] from comment #4) > This wouldn't happen to be related to bug 1052738, would it? No because you have to press resume twice there -- the breakpoint is actually getting hit two times on the same line. If you were stepping and on the second pause <return> was added to the variables view, then it would be, but that's not the behavior.

How about instead of requiring the user to step out twice, we return to the caller immediately after the first step out, but show the returned value in the variables view under <return value>, then remove it again after the next step.

Sounds pretty good, but I'd like to see it in action and play with it to make sure that it isn't just as confusing in practice.

I like this.

This came up in bug 1013219 as well. I find the double stop a bit weird when using the debugger. It's more reassuring when the debugging line marches through the source -- when it stays in the same place I wonder if I clicked the button or not. Since the bytecode emitter knows what is going on, one possible fix would be to extend Debugger.Script to expose this information. Then the debugger would have enough information to allow both setting a breakpoint on an empty function, and also to know to silently continue past the final stepping stop in a function (presenting the user with an apparent single stop due to the onPop handler).

Not actively working on this at the moment. Unassigning myself so other people can take a shot at this bug. However, I might take another shot at it when I get back from vacation.

Upstream ticket? https://github.com/devtools-html/debugger.html/issues/3390

That upstream ticket is the one I filed when I was going to investigate this bug and then found out that the feature isn't working. However, they aren't the same bug -- once the upstream bug is fixed, the double-stepping problem (this bug) will remain. FWIW my plan for fixing this bug was to add a new method to Debugger.Script that would indicate whether a given offset held a return instruction. Then, change the actor so that a stop at a return instruction would install the onPop handler and continue. This way, breakpoints could still be set at the end of a function without undue complication; but stepping would no longer double-stop.

(In reply to Hubert B Manilla from comment #13) > Created attachment 8975247 [details] [diff] [review] > bug-923975-fix.patch I don't understand how this patch works. Maybe I don't understand the original bug, either. I thought what's going on in the present code was this: - We single-step to a return instruction, attributed to source location A. This is all fine from the user's point of view. - We single-step again. The frame's onPop handler runs, with the frame still located at A. We call pauseAndRespond, meaning that the user sees a second pause at the same location, this time displaying the return value or thrown exception. With this patch, it looks as if it's still the case that steppingType == "step" in the onPop handler, so the onPop handler will display a pause. How does this work?

So I think if we don't set an onPop handler on parentFrame as well, hitting this path when an exception is being propagated will cause the debuggee to continue, and get away from the user. You should be able to adapt the test case to see whether I'm right about this. If so, this code should behave more like _handleResumeLimit does for a real "next", and set on onPop handler for parentFrame as well.

I'd also like to understand this patch. I think a comment before the new "if" block would go a long way. Maybe the idea is to notice when a step pops a frame, and instead of reporting that stop, report a stop in the outer frame? Like comment #6 suggested.

I think showing the return in the outer frame could make sense. Let me see if i understand this correctly, > function f() { > debugger > return 3 > } > > f() + f() Lets say the user pauses in f() on line 2 and steps out. I think it would be nice to pause at the 2nd f and show `<return> 3`. I wonder if it would always be possible to have the return value though given we are no longer in that environment. Also, does this work in the case of async functions e.g. `async function g() {}`.

So this patch is trying to fix the step-out bug, we want to jump out to the caller frame on step-out, but step-in and step-over will still go normally and pause at the end of the function

Wondering if it might be confusing... but i guess we can implement and see how it feels. Good point on the async case, i'll test it out too.

just tried it out and it worked magically. I love it!

Just to clarify, if we have this example `f(g())`and we're paused in `g` and step out, do we expect to be at `f` or inside of `f`? I would assume at `f`.

Yes so with `f(g())` we are at f. Interestingly though if we have f(g(h())). and we're paused in `h` and step out , it does not stop at `g` but goes straight inside `g`. stepping out from that then stops at `f`

oh, good to know... Any idea why? Jason, what would you expect to happen here?

FYI, bug 1314057 removed browser_dbg_stack-07.js. Not sure if that newly-added sub-test needs to be re-added elsewhere or not.

That test was re-added in other tests. Thanks for checking!
