I've been hesitant about using gmock, but this is a nice way to test this
without having to create a fake CaptivePortalTabService and injecting it in.

[mmenke, 2012/04/18 19:15:46]

I haven't used it in the past, but simonjam's used it quite heavily in the
HttpPipelining tests, which has gotten me familiar with some cases in which they
can simplify life.

[cbentzel, 2012/04/18 15:57:23]

That is a bit of an unusual pattern. Hope the memory bots don't worry about it.
Why not just instantiate a TestingProfile or similar?

[mmenke, 2012/04/18 19:15:46]

Because the profile shouldn't be dereferenced.  If we end up deferencing it
unexpectedly, we're suddenly depending on something we shouldn't be.  It also
increases how long the test takes by a factor of 60, though admittedly, the
tests are still fast.

I believe I've seen this done before, but can't remember in what test.  The
downside of this approach is we crash if it fails, so obviously not something to
do in a test that's likely to become flaky.  These tests never enter a message
wait, or depend on out of order events, so I think we're fairly safe.

Since it's never dereferenced, but only used as an index in a map, I don't think
the memory bots will care, unless they tract the C++ type of all variables in
the code as it runs, which I don't believe they do.

That having been said, if you think this is a bad idea, or would just prefer me
to use a TestingProfile, I'm happy to do so.

[cbentzel, 2012/04/18 21:12:37]

You may want to ask Qin about this. I agree that it shouldn't be dereferenced,
and this will help catch that.

[mmenke, 2012/04/19 15:26:25]

Qin's response:

1. for the good behavior, i.e. if the junk pointer is never de-referenced I
don't see why it would be a problem. 
2. for abnormal behavior, i.e. if it's deliberately de-referenced and the fault
is masked then the tools will report errors that will have to be suppressed (or
annotated away), which might have some performance hit, depend how frequently it
happens.
   One thing to be careful is that if the junk value is chosen poorly, maybe it
could anchor a leak and cause a false negative (or primary to possible
downgrade) but that seems unlikely.


So I think we should be fine.

[cbentzel, 2012/04/18 15:57:23]

Is there any potential for flakiness here, or is the TimeDelta() for the SSL
guaranteed to always be handled during this loop?

[mmenke, 2012/04/18 19:15:46]

No.  PostDelayedTask and PostTask are both internally mapped to the same code,
PostTask just uses a delay of 0, while PostDelayedTask uses whatever value is
passed it, in milliseconds rounded up.

So, assuming it's safe to do with PostTask, it's safe to do with PostDelayedTask
with a delay of 0 as well.

[cbentzel, 2012/04/18 15:57:23]

It doesn't look like there is a test for when the captive portal is detected
while the Timer is running. You could imagine this happen if the user opened one
tab and navigated to https://foo.com which times out and triggers the
CheckForCaptivePortal. Before we get a response, a second tab is opened to
https://bar.com.
