java - data provider with arraylist of array in Test NG -


i have send array list of arrays test case using dataprovider annotation. have below code giving illegal argument exception. arraylist size 4096. need give such many arguments in test method. 

 @test(dataprovider="combination_list")  public void checkbox_combination(list<int[]> obj) {       /*for(int i=0;i<=4095;i++) {      }*/ } @dataprovider(name="combination_list") public static object[][] get_combination_list() {      list<int[]>  combinations_with_int_array = new arraylist<int[]>();      int size_combination;      for(int i=0;i<=4095;i++) {          string checkbox_combination =combination_list.inttostring(i,12);          int[] single_combination = new int[12];          (int j=0;j<=11;j++) {              if(j<11)             {                  single_combination[j]=integer.parseint(checkbox_combination.substring(j, j+1));              }             else             {                 single_combination[j]=integer.parseint(checkbox_combination.substring(j));              }         }         combinations_with_int_array.add(single_combination);      }     size_combination=combinations_with_int_array.size();      system.out.println("no of combinations : "+size_combination);      object  objarray[][] = new object[size_combination][];      for(int i=0;i<size_combination;i++){          objarray[i] = new object[1];          objarray[i][0] = combinations_with_int_array.get(i);     }      return objarray; }

combinations_with_int_array arraylist of int[]. 

objarray[i][0] = combinations_with_int_array.get(i);

when on list, give int[] type of argument, adding object[][]. test method should have same argument.

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

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
