Dmitri Shuralyov 6a08e3108d playground: use stdlib instead of appengine packages ... With modern versions of App Engine, it's no longer needed to use the google.golang.org/appengine/... packages. Package log from standard library can be used instead of the google.golang.org/appengine/log package. Packages net/http and context from standard library can be used instead of google.golang.org/appengine/urlfetch. This simplifies the code and reduces the number of dependences. Start using the golangorgenv package from previous commit to make the decision of whether to enforce sharing restrictions, rather than relying on the appengine build tag. The appengine build tag is no longer set in App Engine Standard with Go 1.11+ runtime. An alternative solution would be detect App Engine by doing something like: // GAE_ENV environment variable is set to "standard" in App Engine environment, Go 1.11 runtime. // See https://cloud.google.com/appengine/docs/standard/go111/runtime#environment_variables. var onAppengine = os.Getenv("GAE_ENV") == "standard" But we choose to upgrade to explicit app-scoped environment variable configuration as part of this change. It provides better security properties, and the value of adding an intermediate transitional step is not high enough to justify doing it. When getting the value of "X-AppEngine-Country" header, use its canonical format "X-Appengine-Country" to avoid an allocation. This does not change behavior. Run go mod tidy (using Go 1.12).
