my issue want understand why in below code references newmember , facebooklogin retained when hit viewdidload method in other segment of code not? can shed light why case?

working code block

class registrationformviewcontroller: miosbaseviewcontroller {     var newmember:member!     var facebooklogin: bool = false      init(member: member, facebooklogin: bool = false) {         self.newmember = member         self.facebooklogin = facebooklogin         super.init(nibname: "registrationformviewcontroller", bundle: nil)     }      required init?(coder adecoder: nscoder) {         super.init(nibname: "registrationformviewcontroller", bundle: nil)     }      override func viewdidload() {         super.viewdidload()         let view = self.view as! registrationformview         view.loadviewwith(member: newmember)         view.customnavbarview.backactionblock = {             self.newmember.deleteentity(miosdatacontext.sharedinstance.managedobjectcontext)             _ = self.navigationcontroller?.popviewcontroller(animated: true)              return         }     } }

broken code block

class registrationformviewcontroller: miosbaseviewcontroller {     var newmember:member!     var facebooklogin: bool = false      init(member: member, facebooklogin: bool = false) {         self.newmember = member         self.facebooklogin = facebooklogin         super.init(nibname: "registrationformviewcontroller", bundle: nil)     }      required init?(coder adecoder: nscoder) {        super.init(coder: adecoder)     }      override func viewdidload() {         super.viewdidload()         let view = self.view as! registrationformview         view.loadviewwith(member: newmember)         view.customnavbarview.backactionblock = {             self.newmember.deleteentity(miosdatacontext.sharedinstance.managedobjectcontext)             _ = self.navigationcontroller?.popviewcontroller(animated: true)              return         }     } }

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 ...
