javascript - SignalR working with groups is not working correctly -


i work signalr. group functionality not working correctly.

here hub:

public class baskethub : hub {     public void login(int companyid)     {         string groupname = "company" + companyid;          ihubcontext context = globalhost.connectionmanager.gethubcontext<baskethub>();          context.groups.add(context.connectionid, groupname);     }      public void logout(int companyid)     {         string groupname = "company" + companyid;          ihubcontext context = globalhost.connectionmanager.gethubcontext<baskethub>();          context.groups.remove(context.connectionid, groupname);     } }

here using server side: 

  public void orderconfirm(orderconfirmmodel orderconfirmmodel)   {         ihubcontext context = globalhost.connectionmanager.gethubcontext<baskethub>();          var groupname = "company" + orderconfirmmodel.companyid;          context.clients.group(groupname).orderconfirm(orderconfirmmodel.didneworder);          context.clients.group(groupname).newordercount(orderconfirmmodel.didneworder);          context.clients.group(groupname).didgetnotification(orderconfirmmodel.basketid);   }

here client:

       $(function () {         var baskethub = $.connection.baskethub;          baskethub.client.newordercount = function (isneworder) {             // code         }          baskethub.client.didgetnotification = function (basketid) {             // code         }          baskethub.client.orderconfirm = function (isneworder) {              // code         }          $.connection.hub.start();     });

here group add , remove client:

    $(function () {     var baskethub = $.connection.baskethub;      $.connection.hub.start().done(function () {         baskethub.server.login($scope.company.id);          $('#logoutbtn').click(function () {             baskethub.server.logout($scope.company.id);         });     });      $(window).bind('beforeunload', function (e) {         baskethub.server.logout($scope.company.id);     }); });

i created group on baskethub's context. however, when try use group, dont reach it. , there no triggered notifications on client side.

i can use below:

context.clients.all.orderconfirm(orderconfirmmodel.didneworder); context.clients.all.newordercount(orderconfirmmodel.didneworder); context.clients.all.didgetnotification(orderconfirmmodel.basketid);

best regards.

i found solution. write angular controller run init every page load (like layout-controller). define hub here , emit functions. singnalr groups work fine.

    $(function () {     var baskethub = $.connection.baskethub;      baskethub.client.orderconfirm = function (isneworder) {         $rootscope.$emit("basketorderconfirm", isneworder);     }      baskethub.client.newordercount = function (isneworder) {         $rootscope.$emit("newordercount", isneworder);     }      baskethub.client.didgetnotification = function (basketid) {         $rootscope.$emit("didgetnotification", basketid);     }      $.connection.hub.start().done(function () {         baskethub.server.login($scope.company.id);          $('#logoutbtn').click(function () {             baskethub.server.logout($scope.company.id);         });     });      $(window).bind('beforeunload', function (e) {         baskethub.server.logout($scope.company.id);     }); });

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
