[davidben, 2015/10/13 19:43:48]

Just return nullptr. nullptr has a distinct type (nullptr_t) so scoped_ptr (and
std::unique_ptr) can handle it.

[mmenke, 2015/10/13 19:55:50]

I'm not sure all of these really belong in this CL - maybe just switch over some
simpler tests that don't use all the fanciness to the embedded test server with
SSL, to make sure it works?  Also wondering if we can break up landing this file
into chunks.  1000-line reviews often don't go well.  Bugs missed,
relanding/re-review is a pain, etc.

[svaldez, 2015/10/13 20:54:44]

Even if we don't land request_helpers in this CL, we'll probably need to land
most of it in one CL, since there's enough overlap in usage of the various
handlers.

At the very least these handlers are correct in terms of the existing tests that
have been migrated to ETS, and I don't think any missed bugs will be too big of
an issue to fix once someone creates new tests that use ETS.

[svaldez, 2015/10/13 20:54:44]

Done.

[mmenke, 2015/10/13 21:08:02]

Just because the trybots pass does not mean this whole thing will land smoothly,
unfortunately.
