angular - CanActivateChildGuard after CanActivateGuard resolve in Angular4 -


i have routing in angular 4 looks this:

let routes: routes = [     { path: '', redirectto: redirect_after_login, pathmatch: 'full'},     { path: 'passwordreset/:token', component: passwordresetcomponent },     {         path: 'app',         component: appcomponent,         children: app_child_routing     },     {         path: 'pages',         component: pagescomponent,         canactivate: [canactivateappguard],         canactivatechild: [canactivateappguard],         data: {breadcrumb: 'breadcrumb.home'},         children: child_routing     } ];

when trigger pages child route (which after login because redirect_after_login variable contains 1 of pages child routes) want execute 2 api calls in direct order: 1. api call server token <-- canactivate 2. api call additional info requires send server token <-- canactivate child.

those api methods observables, canactivate start running , before resolves (return true guard) canactivatechild fired resolves in error. 

canactivate():observable<any>{             return this.loginservice.getuserinfo().map(()=>{                 return true;             }).catch(()=>{                 this.redirect(location.origin + "/login");                 return observable.of(false);             })     }      canactivatechild():observable<any>{         return this.common.retrievecontext().map(             res=>{                 //do sth                 return true;             },             err=>{                 //do sth else                 return observable.of(true);             }         )     }

i want find way canactivatechild guard fired when canactivate guard has been resolved.

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 ...
