How to reuse sockets in .net using beginaccept -

i experimenting socket re-use on asynchronous http server writing, although code recycles .net part of socket fine, netstat shows new socket handles opened when recycled .net socket passed through beginaccept , hence server crashes under load. of import think doesn't happen under low load guess has latency of begindisconnect ?? running on mono 2.10 on ubuntu 10.04 insight grateful received. have researched quite thoroughly on google no avail.

using system; using system.io; using system.net; using system.net.sockets; using system.text; using system.collections.generic; using system.threading.tasks; using system.threading; public class server{ public static queue<socket> sockets=new queue<socket>(); public static manualresetevent alldone = new manualresetevent(false); public static void main (string [] args) { int port=81; var listensocket = new socket (addressfamily.internetwork, sockettype.stream, protocoltype.tcp); ipendpoint localendpoint = new ipendpoint (ipaddress.any, port); listensocket.bind (localendpoint); listensocket.listen (10); while (true) { console.writeline(sockets.count); try{ alldone.reset(); socket connectingsocket; if (sockets.count<100) { // populate queue reusable sockets connectingsocket=new socket (addressfamily.internetwork, sockettype.stream, protocoltype.tcp); } else { connectingsocket=sockets.dequeue(); //use existing socket queue } listensocket.beginaccept(connectingsocket,5,ar=>{ try{ socket socket=listensocket.endaccept(ar); console.writeline(connectingsocket.gethashcode()+" "+connectingsocket.connected); console.writeline(socket.gethashcode()+" "+socket.connected); socket.send(encoding.ascii.getbytes(@"http/1.1 200 ok\n\rcontent-type: text/html\n\rconnection: close\n\r\n\rhello world!!")); socket.begindisconnect(true,ar2=>{ //socket client = (socket) ar2.asyncstate; socket.enddisconnect(ar2); server.sockets.enqueue(socket); //return disconnected socket queue re-use } ,null); alldone.set(); } grab (exception e){ console.writeline("captured:"+e); } },null); alldone.waitone(); } grab (exception e){ console.writeline("captured:"+e); } } } }

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...

javascript - mongodb won't find my schema method in nested container - i trying access method of schema stored within mixed container. here situation : have cases model can many different things, have schema each of these things stored in "casecontent" mixed property. var caseschema = mongoose.schema({ casecontent : {}, object : {type:string, default : "null"}, collision : {type : boolean, default : false} }); the casecontent property filled model of 1 of schemas, 1 exemple : var treeschema = new mongoose.schema({ applecount : {type : number, default : 3} }); treeschema.methods.dostuff = function (data) { console.log('hey, listen'); homecoming true; }; then, want utilize method of schema original container : caseschema.methods.dostuff = function (data) { if (this.casecontent.dostuff !== undefined) { this.casecontent.dostuff(); console.log('it worked'); } else { ...
