c# - HttpClient.PostAsJsonAsync throws TaskCanceledException -


i'm using httpclient.postasjsonasync , post never sent. i'm monitoring wireshark , nothing goes out.

i feel deadlocking in here can't figure out what. i've read this guide , followed still nothing. i've tried both configureawait(false), async, await, creating new task async method, call never returned , post never made. 

public class requestdespacho     {      /*           several public properties     */     public async void makerequest()             {                 try                 {                                         var response = await requester.makepost("createticket/", this);                     switch (response.statuscode) //this line never reached                     {                         case httpstatuscode.ok:                             messagebox.show("ok");                             break;                         case httpstatuscode.forbidden:                             messagebox.show("forbidden");                             break;                         case httpstatuscode.badrequest:                             messagebox.show("bad request");                             break;                         case httpstatuscode.internalservererror:                             messagebox.show("internal server error");                             break;                     }                  }                 catch (exception e) //taskcanceled exception appears after while                 {                     messagebox.show(e.tostring());                 }              }     } public static class requester     {         private static readonly httpclient client;          static requester()         {             client = new httpclient()             {                 baseaddress = new uri("http://10.2.4.29:1234/"),                 defaultrequestheaders = {{"x-auth_token", "token1"}},                 timeout = new timespan(0, 0, 15)             };         }         public static async task<httpresponsemessage> makepost(string dir, object data)         {             return await client.postasjsonasync(dir, data);         }     } public partial class form1 : form {     private async void button3_click(object sender, eventargs e)         {             var image = file.readallbytes(@"g:\1.jpg");             requestdespacho req = new requestdespacho("av. monroe 2323", -34.557762, -58.459346, tipoevento.merodeo,                 "palio rojo", image); //my model, doesn't matter             await req.makerequest();         } }

it network related issue. conected wifi usb board , problem solved. still got no idea blocked requests...since postman worked in visual studio didn't...but code allright.

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 ...
