Which parts of HTTP/2 are stateful?

问题 Unlike stateless HTTP/1.0, HTTP/2 has stateful components. These parts appear stateful: opportunistic encryption framing layer header blocks This part appears to be stateless: application layer Are there any other parts of HTTP/2 are stateful? 来源： https://stackoverflow.com/questions/33682693/which-parts-of-http-2-are-stateful

Meta programming: Declare a new struct on the fly

由 匆匆过客 提交于 2019-12-04 23:31:40
Is it possible to declare a new type (an empty struct , or a struct without an implementation) on the fly? E.g. constexpr auto make_new_type() -> ???; using A = decltype(make_new_type()); using B = decltype(make_new_type()); using C = decltype(make_new_type()); static_assert(!std::is_same<A, B>::value, ""); static_assert(!std::is_same<B, C>::value, ""); static_assert(!std::is_same<A, C>::value, ""); A "manual" solution is template <class> struct Tag; using A = Tag<struct TagA>; using B = Tag<struct TagB>; using C = Tag<struct TagC>; or even struct A; struct B; struct C; but for templating /

Stateful LSTM and stream predictions

问题 I've trained an LSTM model (built with Keras and TF) on multiple batches of 7 samples with 3 features each, with a shape the like below sample (numbers below are just placeholders for the purpose of explanation), each batch is labeled 0 or 1: Data: [ [[1,2,3],[1,2,3],[1,2,3],[1,2,3],[1,2,3],[1,2,3],[1,2,3]] [[1,2,3],[1,2,3],[1,2,3],[1,2,3],[1,2,3],[1,2,3],[1,2,3]] [[1,2,3],[1,2,3],[1,2,3],[1,2,3],[1,2,3],[1,2,3],[1,2,3]] ... ] i.e: batches of m sequences, each of length 7, whose elements are

Why shouldn't I use a JSF SessionScoped bean for logic?

由 会有一股神秘感。 提交于 2019-11-30 14:14:35
问题 I'm developing a java EE web app using JSF with a shopping cart style process, so I want to collect user input over a number of pages and then do something with it. I was thinking to use an EJB 3 stateful session bean for this, but my research leads me to believe that a SFSB is not tied to a client's http session, so I would have to manually keep track of it via an httpSession, some side questions here . . . 1) Why is it called a session bean, as far as I can see it has nothing to do with a

Differences : @SessionScoped vs @Stateful and @ApplicationScoped vs @Singleton [closed]

由 雨燕双飞 提交于 2019-11-30 08:47:54
I would like to know, what are the principal differences between : javax.enterprise.context.SessionScoped and javax.ejb.Stateful javax.enterprise.context.ApplicationScoped and javax.ejb.Singleton I know that a @SessionScoped and a @Stateful allows to create a new instance for each client. I also know that for the @ApplicationScoped and @Singleton / @Stateless they are shared between the clients. => But when should I consider it's better to choose an EJB, or the other? @SessionScoped denotes a scope while @Stateful is in a way what we would now call a stereotype. @Stateful adds a number a

How good and/or necessary are Stateful Web Services?

What kind of server do you people see in real projects? 1) Web Services MUST be stateless: Basically you must send username/password with every request, every request must use HTTPS and I will authenticate and load the User object everytime if needed. 2) A Session for Web Services: like in a web container so I can at least save the authenticated User object and have something similar to a session ID so I don't need to authenticate, load and check the User on every request. 3) Sticky Service (persistent service across requests): https://jax-ws.dev.java.net/nonav/2.1/docs/statefulWebservice.html

Stateful vs. Stateless Webservices

问题 Imagine a more complex CRUD application which has a three-tier-architecture and communicates over webservices. The client starts a conversation to the server and doing some wizard like stuff. To process the wizard the client needs feedback given by the server. We started a discussion about stateful or stateless webservices for this approach. I made some research combined with my own experience, which points me to the question mentioned later. Stateless webservices having the following

Stateful Web Services

由 我是研究僧i 提交于 2019-11-29 12:38:48
I'm building a java/spring application, and i may need to incorporate a stateful web service call. Any opinions if i should totally run away from a stateful services call, or it can be done and is enterprise ready? Stateful web services are a pain to maintain. The mechanism I have seen for them is to have the first call return an id (basically a transaction id) that is used in subsequent calls. A problem with that is that the web service isn't really stateful so it has to load all the information that it needs from some other data store for each call. Statefulness runs counter to the basic
