Configure Scope in Transaction/Request

[billypap1]

I use Sentry in my Go App - Gin and I set scope in a middleware.
Before each route I set user details (via the middleware):

sentry.ConfigureScope(func(scope *sentry.Scope) {
	scope.SetUser(sentry.User{Email: "jane.doe@example.com"})
})

ConfigureScope is configured globally or per each transaction/request that Gin handles?

You might end up with something we call scope bleed by using the global function; hence I recommend something like this in your middleware:

hub := sentry.GetHubFromContext(ctx)
if hub != nil {
    hub.ConfigureScope(func(scope *sentry.Scope) {
	scope.SetUser(sentry.User{Email: "jane.doe@example.com"})
    })
}

@cleptric I want to set the user only for this specific request/transaction. Should I set it in hub?

[cleptric]

Yes, the hub is cloned on each request, and the correct scoping is guaranteed per request.
