can errors non-awaited async call caught, sent original encapsulating try/catch, or raise uncaught exception? here's example of mean: async function fn1() { console.log('executing fn1'); } async function fn2() { console.log('executing fn2'); throw new error('from fn2'); } async function test() { try { await fn1(); fn2(); } catch(e) { console.log('caught error inside test:', e); } } test(); in scenario, error thrown fn2 swallowed silently, , not caught original try/catch . believe expected behavior, since fn2 being shoved off event loop finish @ point in future, , test doesn't care when finishes (which intentional). is there way ensure errors not accidentally swallowed structure this, short of putting try/catch internal fn2 , doing emitting error? settle uncaught error without knowing how catch it, think -- don't expect thrown errors typical program flow writing, swallowin...

i have problem using polymorphism. code here: class { public: a() {cout << "construct a" << endl;} virtual ~a() {cout << "destroy a" << endl;} }; class b : public a{ public: b() {cout << "construct b" << endl;} ~b() {cout << "destroy b" << endl;} }; void main() { *p = new b; } the result is: construct construct b why 'p' can not destroyed or may wrong somewhere. thanks. you need invoke delete p; to delete pointer , call destructor. dynamically allocated objects not have destructor called automatically, that's why need invoke delete operator, first invokes destructor calls operator delete release memory.

first, context (pardon pun). consider following 2 async methods: public async task async1() { prework(); await async2(); postwork(); } public async task async2() { await async3(); } thanks async , await keywords, creates illusion of nice simple call stack: async1 prework async2 async3 postwork but, if understand correctly, in generated code call postwork tacked on continuation async2 task, @ runtime flow of execution more this: async1 prework async2 async3 postwork (and it's more complicated that, because in reality use of async , await causes compiler generate state machines each async method, might able ignore detail question) now, my question : there way flow sort of context through these auto-generated continuations, such time hit postwork , have accumulated state async1 , async2 ? i can similar want tools asynclocal , callcontext.logicalsetdata , aren't quite need because contexts "rolled back" work w...

i understand in go, runtime.lockosthread() bind goroutine 1 os thread , not allow other goroutines execute in thread. true child goroutines? for example: runtime.lockosthread() go func() { go func() { // }() // }() do both of these goroutines execute in single , exclusive os thread or first one? the documentation runtime.lockosthread says: lockosthread wires the calling goroutine current operating system thread. until calling goroutine exits or calls unlockosthread, execute in thread, and no other goroutine can . (emphasis mine) this means if implementation of go did you're asking, faulty. to clarify: if goroutine had reserved thread , goroutine executed on same thread; that's wrong.

i coding gui in python , pyqt , parts of logic needs executed in specific time intervals measured in ms. think running parts threads , keep track of time best please correct me if wrong. second question, can use threads classic objects , use them in same way? call methods or use them specific task , keep them simple possible? because thread nature tempted write run() method procedure , somehow lacking oop approach. thanks 1st part: if timed part of code rather computation heavy in qthread - if not there no need make things complicated. as said x3al in comment, there no obvious reason why should not able timing using qtimer. if need repeating signal can use setinterval . if single signal after x ms can use singleshot ( pyqt4-doc ). 2nd part: if part correctly asking advice on how use threads - depends on implementation (movetothread vs subclassing), have @ answers background thread qthread in pyqt allow me recycle example used before on matter: class thr...

i have actor creates router. when work done want stop current actor, stop router , routees. this code stop hierarchy: // stopping children context.children foreach context.stop // stopping current actor context.stop(self) but in log i'm getting messages this: message [akka.dispatch.sysmsg.terminate] ... ... not delivered. [5] dead letters encountered. i.e. routees sends terminate message itslef. i think problem related code stopping actors (above). how can fix it? when stop self, children stopped automatically. use context stop self .

the user can insert random string can contains numbers. must been possible calculate integer. the problem user insert string 010 + integer(1) result in 11; but want return string 011 but user can enter numbers 001, 0001, etc what best approach here? have try use string.format("%05d", yournumber); not work variable strings i came across string str = "abcd1234"; string[] part = str.split("(?<=\\d)(?=\\d)"); system.out.println(part[0]); system.out.println(part[1]); if use got new problem. how split number in right way. any idea i'm missing considering handling integer number (not binary ) try this: string input ="001";//your user input /** * check here if input number */ int len=input.length(); int inputinteger=integer.parseint(input); inputinteger+=1; string output=string.format("%0"+len+"d", inputinteger); system.out.println(output);

i found funny behaviour using equal pdo. checked several select-statements in phpmyadmin , pdo , results vary. has idea whats wrong? $sql = "select * fenster fenster > 'news'"; //works ok $sql = "select * fenster fenster < 'news'"; //works ok $sql = "select * fenster fenster <= 'news'"; //works ok $sql = "select * fenster fenster >= 'news'"; // news not in result $sql = "select * fenster fenster = 'news'"; // news not in result $stmt = $db->prepare($sql); $stmt->execute(); $feldname = array_keys($stmt->fetch(pdo::fetch_assoc)); while($data = $stmt->fetch()) { var_dump($data); } i found reason myself. $feldname = array_keys($stmt->fetch(pdo::fetch_assoc)); did read missing row, did not show afterwards. have find workaround.

i'm trying use react simplify way build ui app i'm writing. i've got proof of concept working in single html page, need split out js individual modules make easier maintain. i know how structure app if every piece of puzzle known @ build time. this: https://github.com/jordwalke/reactapp . however, ui built dynamically in php, nesting various components want pass app. my initial thought of dumping generated code script tag , having javascript find has led me horrible dependencies hell. my primary question is: how pass <panel><group><field /></group></panel> app can call react.render() on it? as @llernestal , @mikedriver suggested in comments, used php build json representation of ui , had react build components needed render ui.

i'm doing api rest , saw in lot of examples people use entityutils.tostring(response) response string get , post , put , delete methods. similar this: httpget method = new httpget(url); method.setheader("content-type", "application/json"); httpresponse response = httpclient.execute(method); string responsestring = entityutils.tostring(response.getentity()); please avoid answers said me gives me string i know returns me string content of entity (in case response) here doubts come, because i'm not secure string returns. saw official documentation. read contents of entity , return string. https://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/util/entityutils.html#tostring(org.apache.http.httpentity,java.lang.string) it content-type returned in string ? on contrary, values i'm getting method returned in string ? i think second 1 question i'm not secure that. and, in case true, how values stored stri...

i have enum. and each value in enum, need associate data (actually in case, it's integer, know more generally, instance 2 integer values, or 2 strings etc). those values can't accessible user. in case of reverse engineering, well, can't much, should ask user effort modify it. can't in config file or in db etc. so thinking about: hardcode them in case, what's elegant (least horrible) method? hardcode pair, triplet in namespace store in hash [enumvalue]->[struct]? store in file compiled resource file (although accessible tools, ask bit more effort user). checksum make sure wasn't modified if necessary guess? what thoughts? to summarize, have enum containing val1, val2 ... and associate like: val1 has length 5 , name "foo" val2 has length 8 , name "bar" i might missing other easy solution though this code adapted solution found while ago on stackoverflow post - if can find original link again i'll include...
