algorithm - C# system.timers.timer weird behavior -


i trying implement bully coordinator election algorithm. in algorithm, coordinator sends alive message every 10 seconds , processes wait @ least 14 seconds receive alive, if don't receive message within time, initiate dead coordinator election.

the problem alivetimer (timer3_count) increasing exponentially , active processes affecting it. don't know why behaving weirdly.

when initial coordinator sending alive message counter works after dead coordinator election, behaves weirdly.

else if (received_text.contains("alive:"))             {                 settext(received_text + "\n");                 coordinator_alive = true;                  timer3_counter = 0;                  if (alive_count == 0)                 {                     alive_count++;                       alivetimer.interval = (1 * 1000);                     alivetimer.enabled = true;                     alivetimer.elapsed += new system.timers.elapsedeventhandler(alivetimer_elapsed);                     alivetimer.start();                  }              }

the elapsed function here think there wrong program, tried everything.

private void alivetimer_elapsed(object sender, eventargs e)     {         timer3_counter++;         settimer(timer3_counter.tostring());          random rnd = new random();         int rand_time = rnd.next(14, 18);          if (timer3_counter == 14)         {             alivetimer.stop();              timer3_counter = 0;             alive_count = 0;              if (coordinator_alive == false)             {                 byte[] buffer = encoding.ascii.getbytes("dead coordinator election: " + txname.text);                 _clientsocket.send(buffer);                  timer4_counter = 0;                  deadtimer.interval = (1 * 1000);                 deadtimer.elapsed += new system.timers.elapsedeventhandler(deadtimer_elapsed);                 deadtimer.enabled = true;                 deadtimer.start();              }          }          if (coordinator_alive == true)             coordinator_alive = false;      }

and dead coordinator election code here

else if (received_text.contains("dead coordinator election:"))             {                 setcpid("");                 coordinator_alive = false;                 alive_count = 0;                 timer3_counter = 0;                  alivetimer.stop();                 alivetimer.enabled = false;                   string output = regex.match(received_text, @"\d+").value;                 settext("dead coordinator election received process id: " + output + "\n");                  if (convert.toint32(txname.text) > convert.toint32(output))                 {                     byte[] buffer = encoding.ascii.getbytes("greater process no: " + txname.text + " found " + output + "\n");                     _clientsocket.send(buffer);                     settext("our process no: " + txname.text + " greater " + output + "\n");                     lower_count++;                      byte[] buffer1 = encoding.ascii.getbytes("dead coordinator election: " + txname.text);                     _clientsocket.send(buffer1);                 }                 else                 {                     byte[] txt_send = encoding.ascii.getbytes("our process no: " + txname.text + " less " + output);                     _clientsocket.send(txt_send);                     greater_count++;                 }              }

the full code can found here bully algorithm

note: using passive server broadcast messages each process

i don't know causes problem, think you able figure cause if log start , stop all methods , analyse output.

this establish if: 1. @idle_mind suggested, adding more , more handlers 2. time taken execute each method creeps , more...

i don't know how app built can start console.writeline or debug.writeline.

vue.js - Create hooks for automated testing -

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...

Add new key value to json node in java -

i have json file : { "id":1, "name":"abc", "addressdetails": { "city":"newyork" } } i wanted add 1 more key-value ("pincode" : "414141") node 'addressdetails'. i tried using : objectmapper mapper = new objectmapper(); jsonnode root = mapper.readtree(new file("d://test.json")); objectnode node = mapper.createobjectnode(); node.with("addressdetails").put("pincode", "414141"); but it's not getting added, there way can ? you can try you should modify file path objectmapper mapper = new objectmapper(); objectnode nodes = mapper.readvalue(new file("d:\\test.txt"), objectnode.class); nodes.with("addressdetails").put("pincode", "414141"); mapper.writer().writevalue(new file("d:\\test.txt"), nodes);
