Will this patch also include state transitions within the GSM state machine, i.e. the fsmdef_function_table?

I would be good to print out the state number to aid debugging, especially since we get some locks here.

This message says dcb is null, shouldn't it instead say we can't do this in sdpmode?

Review of attachment 745896 [details] [diff] [review]:

review- for signaling state checks being unreliable.
There's some smaller cleanup needed as well.
We'll need a separate reviewer for signaling tests also.

It feels a bit awkward to be doing signaling state checks as part of the local and remote gum commands. Maybe we should add a new command that happens before PC local offer that checks correct creation state?

For all of these internal handshake signaling state checks, see the comment below about the reliability problem that exists with how these checks are being done vs. asynchronous nature of the event handler, onsignalingstatechange.

This isn't going to be reliable in CI. The onsignalingstatechange event is fired asynchronously away from the handshake during phases of the handshake. Whether that fires on time or not can vary based on if there's bugs present in the code or not.
What you should do here instead is that if you are expecting the callback to fire as a result of a handshake action, then you should wait for this event to fire before completing the command. If you are not expecting the event to fire, then you should have a stubbed failure test fire if the event handler unexpectedly fires.
If you move to an expectation model of when you expect the event to fire vs. not, then you could greatly simplify the checks shown above in the commands list into a reliable approach.

If you do that, won't test_peerConnection_bug840344.html fail from an unexpected INVALID_STATE error callback, until I back you out in https://hg.mozilla.org/integration/mozilla-inbound/rev/13c45a7334fc?

Erk. Sorry about that; I'd kept in mind that these could each be applied independently, but forgot that the bug840344 test case has been completely invalidated by the new behavior. So I guess I'll have to land all four of these as a single unit.

Not right now. Presently, we're just passing around hashes with the proper keys in them. That might change in the future, but I'd prefer to document the current state of things.

Part 4: signalingState tests
Review of attachment 750854 [details] [diff] [review]:

For mochitest changes - very close. You've got one remaining issue with a potential race condition that could cause intermittent failures.

So there's one potential race condition that could happen here or below that could get you stuck in the test - you could end up in a case where you could get false in this if statement here and below in pcw.signalingChangeEvent if the timing of when the events fire just right to have this happen.
What I'd suggest to do here to mitigate this is have one of the functions handle the "wait for these conditions to be true" before proceeding to the next command. That means do the following in one of the two functions:
while(!pcw.commandSuccess || !pcw.SignalingChangeEvent) {
// sleep for some period of time before doing another check
}
text.next();
That will ensure that we only move forward if all conditions are met, even if timing plays against us. If we get stuck in the loop, then the mochitest will eventually timeout.

Jason: I don't think the race you highlighted can happen. Keep in mind that all of this must execute on the main thread. I concede that the ordering of the success event versus the onsigalingstatechange event might be variable (I don't know enough about event processing to know whether they can be reordered -- I doubt it, but can't refute it); however, I'm 100% certain that one of them will run to completion before the other one starts. There is no concurrency possible here.

I'm pushing the first two patches to try (after removing dom/media/tests/mochitest/test_peerConnection_bug840344.html) to verify that they don't cause problems. I want to land the bottom half of this patch so I don't have to keep un-rotting it. The removal of the now-defunct mochi test is part of the "Part 4" patch that Jason has already approved.

Oh. I didn't even notice in the patch I got flagged review on that was test was being removed (saw it on the other patch just now). Why are we removing that test specifically?

That test was checking for unsafe behavior when a specific (invalid) set of API calls was made. With the state machine checking, that invalid sequence is detected and thrown out much earlier in processing (either by throwing an exception or by calling an error callback, depending on the outcome of a conversation I need to conclude with EKR).
In any case, test_peerConnection_bug840344.html is trying to call "setLocalDescription(answer)" in the state "stable". I could fix it to check that the right thing happens under those circumstances, but that would make it identical to the new test_peerConnection_setLocalAnswerInStable.html.

Ah okay. If it ends up being identical to the newer test, then that's fine.

Because it was going in the wrong place. I'm sure this was broken as received, but it was in the way when I was performing some refactoring pertaining to this patch.

(In reply to Eric Rescorla (:ekr) from comment #31)
> Why not event->state?
Semantically, what we want to compare to is the state reflected in the FCB, since that's authoritative. For example, if later changes were to call fsm_change_state(), then the change is reflected in the FCB, but not in the event. Even if the prospect of calling fsm_change_state() in this function is implausible, using event->state runs the risk of doing The Wrong Thing if it gets cargo-culted into some other part of the code.
The code changes from "event" to "fsm" -- here and elsewhere -- arose out of an attempt to rationalize the code's confusion between events and states. Untangling that mess ended up being more profound than was warranted by this bug; however, the changes to clean up related code do technically make it "more correct," and pave the way for future efforts to clean that particular mess up in the future (if we decide such clean up is worth the effort).

Part 3: Send Signaling State from SIPCC to PeerConnection
The interdiff on this appears to be completely broken (it shows the reverse of changes I made in some places), probably because I had to un-rot the patch a few times to match the state of the tree.
I believe this addresses each of your comments from the previous review. You had a couple of "why" questions in your review, which I've addressed in comments above -- those two comments did not result in any code changes.

I'm not entirely certain. This function is a trivial refactoring of the code of the code that already existed in CreateOffer() and CreateAnswer(). If you check the code currently present in CreateAnswer(), it does exactly this:
> nsRefPtr<DOMMediaStream> domMediaStream = new DOMMediaStream();
I could chase down this rabbit hole if you insist, but I'm happy moving forward with the assertion that my refactoring does not change existing behavior -- behavior unrelated to my changes -- without knowing exactly why or whether that behavior is 100% correct.

A quick glance through PeerConnectionImpl leads me to believe that the behavior is still hint-based. If you think this is wrong, I would ask you to open a new bug on that issue.
I have addressed the remaining points you raise in the upcoming patch.

Comment on attachment 755735 [details] [diff] [review]
Part 4: signalingState tests
EKR: This should address all the comments that I haven't otherwise responded to.
Jason: You'll probably want to re-review the mochi tests. Based on conversations between me and EKR, and subsequent discussions on the webrtc mailing list, we determined that it is more appropriate to use error callbacks for operations in invalid states (rather than exceptions, which is what we had implemented before). There are some changes in pc.js (e.g., setRemoteDescriptionAndFail), and every new mochi test has been updated to expect error callbacks rather than exceptions.

This is just a review of the C++ code. I think it still neeeds some work.

This seems more complicated than needed. Wouldn't it be easier to just implement
something that accepted << and did a character-by-character write?

how about a static function along the lines of:

I went ahead and split the tests (previously patch 4) into two parts, now patches 4 and 5. They have different reviewers, live in different parts of the tree, and are likely to land at different times -- so splitting them up seemed to make the most sense.

Part 3: Send Signaling State from SIPCC to PeerConnection
[Copying review from reitveld, with an r+ via IM]
LGTM with one bug below.
https://firefox-codereview.appspot.com/17001/diff/23001/dom/media/PeerConnection.js
File dom/media/PeerConnection.js (right):
https://firefox-codereview.appspot.com/17001/diff/23001/dom/media/PeerConnection.js#newcode1015
dom/media/PeerConnection.js:1015:
this._dompc.changeIceConnectionState("completed");
This doesn't look correct. kIceWaiting means that all gathering is done.
I believe this is still "new"
https://firefox-codereview.appspot.com/17001/diff/23001/dom/media/PeerConnection.js#newcode1031
dom/media/PeerConnection.js:1031:
this._dompc.changeIceConnectionState("connected");
So we never go to completed? I guess that's because nICEr doesn't...

I'm fixing the ICE state problem, but the logging issue will be resolved as Bug 879477.

Okay, that's really strange. I just ran crashtests locally several times, and didn't see the crash/exit problem from that log even once. The push log looks like it happened for every run. I wonder whether it's some other patch -- or possibly a clobber issue. In any case, I'm pushing another try, this time for crashtests, to see if the problem is real:

I just noticed that the m-i landing had problems in mochi-3 (which I similarly cannot repro locally). I've cancelled the previous try and issued a new one to run crashtests and mochi-3:

Okay. The clobber build on Android was clean. Also, all the builds that hadn't started by the time philor clobbered the tree have clean mochi and crash (yaay!) while the ones that were already going at that time failed, just like before. So I think the magic chicken to wave for this patchset is touching CLOBBER (which I added to the Part 3 patch).
Third time's a charm; keeping my fingers crossed:

No, it would be against https://bugzilla.mozilla.org/enter_bug.cgi?product=Core&component=Build%20Config - release engineering runs commands, not quite "make -f client.mk build" but roughly that; it's build config that either reviewed a makefile that doesn't actually work, or is going to yell at someone for not getting review from a build config peer for their makefile patch which doesn't actually work.

I've gone with this instead:

Just as an aside here (irrelevant since the class has gone away), but declaring a method as virtual in one class is sufficient to cause it to be virtual in all its descendants. It's a matter of style whether you consider redeclaring such methods as virtual to add clarity or clutter.

Not with streams. The mapping from "\n" to the underlying platform's notion of "end-of-line" happens at a lower layer than we're operating at here.

This is entirely compile-time typechecking sugar. All we would gain from enforcing a range on it would be loss of information. If the state comes out as something unexpected and out of range, I would strongly prefer it show up at the ASSERT_EQ() statement that makes use of signaling_state().

Ugh. The prospect of making redundant copies of a method seems rather extreme overkill. Is your assertion that default arguments as a general programming level construct are bad? If so, I disagree vehemently. I would understand objections if I were using, say, variadic functions here; but default arguments contribute significantly to code readability unless the defaults are just flat-out broken.

Yes. If the state changes from stateNoResponse to stateError, we want to stop waiting right away rather than hanging around for the timeout to fire.

I think you'd need to ask Enda. In any case, it appears to be unused, so I'm removing it.

I think, if we remove it, we run the risk of naïvely forgetting to put it back in after Bug 840728 is fixed.

Given that the correct ending state is trivially derivable from the inputs in all but degenerate cases, that seems to be a far more intrusive approach than providing defaults that are correct in the vast majority of the cases, with overrides necessary only for corner cases. You're talking about needlessly complicating on the order of 64 calling sites.
It kinda seems like the primary use case for which default arguments were introduced to the language.

One could easily imagine bad logic in sipcc setting it to closed ("something went wrong! abort!") or stable ("I wanted a remote description and got a remote description, let's start this session"), both of which would be an error that I want the unit test driver to catch.

So far I can see this method is for callbacks only. Over on bug 796894 (which has not been landed yet) I added another method specifically for events. I don't think we should fold in events here.

Can we do it similarly to what I do in the datachannel patch? If it really should only fire once, we might want to also catch unexpected events of this type.

I have been told for my patch not to add checks like those inside the framework but in the template.

This will not correctly print the event details in the error callback.

Also any reason why you are passing in the test as last argument? This method is already a member of the test and knows about any internal state.

Sorry to add one more note but this totally busts the way how templates can be extended. None
of our framework methods should call test.next() itself, but should always allow to specify a onSuccess callback which will be called instead. test.next() should only be called from the templates or custom steps of the command chain.
This makes it kinda hard to to update my datachannel framework changes. :/ Can we get this fixed please?

Henrik - The mochitest patches are already landed at this point. File a followup for the fixes needed here.

This bug is still open, so I do not see the necessity to file a new bug for it. Lets wait for Adam's reply and if he wants to fix it. I don't really have the time for that. So long I'm blocked with my datachannel test patch.

Why are these patch changes blocking you on your data channel automation patch?

That tests as written here we're not designed to handle the data channel framework you were working on - they were written before the updated patches showed up on your bug. These are valid comments, but I'd expect this would need to be fixed on your patch, not this patch.
Comment 91•12 years ago

I don't want to start a large discussion on that while the problem is most likely also clear for Adam. Just in short again, the code as pointed out above should NOT call test.next() but should execute a given onSuccess() callback, so that other code in the same command can hook in. As of now both expectStateChange() and checkStateInCallback() call test.next() and given that I have to do event checks in the same command, only signaling OR datachannel tests can be executed but not both.

Henrik -- I'm sympathetic to the fact that your patch has rotted due to the changes I've landed, but the vast majority of your comments functionally resolve to my failure to predict what you would be doing in the future. I think most (if not all) of the changes you propose need to be included in your impending patch.

For the event that currently calls this, the details of the event are unimportant. If you want to redirect the onsignalingstatechange event to use your new function as part of your impending patch, feel free -- it doesn't help, but it doesn't hurt.

I didn't chase it to ground, but my original attempt (in which I passed in test.next) failed because "test" ended up being undefined by the time the JS got around to calling next().

This does check unexpected events of this type -- note that the signal handler sets "pcw._pc.onsignalingstatechange = unexpectedCallbackAndFinish(new Error);"

That's where I originally had it, but Jason wanted to ensure that the check worked regardless of which order the event versus the callback happened (hence this and the following function). If you can come up with an alternate design that makes you happier and still achieves the same goal, feel free to move things around.

I tried to do that, but (as I mention above), passing test.next() as a success callback didn't work.

The event details, in this case, are completely worthless. All we need to do is determine that the event happened when it shouldn't have.
