C# post request stuck in WaitingForActivation even with timeout -


i trying simple post request using httpclient (which far can tell current correct way handle post requests.) however, code stalling on timeouttask.result, tasks stuck on status=waitingforactivation. looking @ server side of things, can tell post request being sent , data being returned, , have called wget manually , verified text data correctly returned server post request.

this happened when called task.result, tried add timeout task, must making mistake async because still hangs on timeouttask.result.

class httppostexample     {         private static readonly httpclient client = new httpclient();          public void processsentence()         {             string uri = "http://localhost:9000/?properties={%22annotators%22%3a%22tokenize%2cssplit%2cpos%22%2c%22outputformat%22%3a%22json%22}";             string result = postsync(uri, "the quick brown fox jumped on lazy dog");             debug.writeline(result);         }          public static async task<string> postasync(string uri, string postdata)         {             var content = new stringcontent(postdata);             var response = await client.postasync(uri, content);             var responsecontent = await response.content.readasstringasync();             return responsecontent;         }          public static async task<string> runtaskwithtimeout(task<string> task, double seconds)         {             if (await task.whenany(task, task.delay(timespan.fromseconds(seconds))) == task)             {                 // task completed within timeout                 return task.result;             }             else             {                 // timeout logic                 return "timed out";             }         }          public static string postsync(string uri, string postdata)         {             var task = postasync(uri, postdata);             var timeouttask = runtaskwithtimeout(task, 2.0);             return timeouttask.result;         }     }

since calling async method synchronous method may want try , add configureawait(false) on of await lines. idea use async way or add configureawait(false) avoid deadlocks.

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
