This look great already. But I'll need more time to deeply review this, e.g. I'll do another round, this are the few things I found while quickly looking over the patch. src/common/http.hpp (line 132) <https://reviews.apache.org/r/56618/#comment237353> Why `const` when you're returning a value? src/common/http.hpp (line 133) <https://reviews.apache.org/r/56618/#comment237352> How about using an `Option<AuthenticationContext>` here and returning `Subject()` in the case of `context.isNone()`? All calls to this functions in the following patch are either ``` authorization::Subject subject = context.isSome() ? createAuthorizationSubject(context.get()) : authorization::Subject(); ``` or ``` if (context.isSome()) { request.mutable_subject()->CopyFrom(createAuthorizationSubject(context.get())); } ``` At least the first form would look much simpler and concise when changing the function signature this way: ``` authorization::Subject subject = createAuthorizationSubject(context) ``` What do you think? - Jan Schlicht On Feb. 14, 2017, 12:46 a.m., Greg Mann wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
