how can exceptions different processes spit out on stdout when using executor pools asyncio? for exceptions trapped in ether , can partially dechiper what's going wrong when kill script via ctrl-c.... here's code: import lib.myfunctions import asyncio import oandapy fmc = lib.myfunctions.fmcmixin() def meatandpotatoes(currency_pair=sys.argv[1], time_compression=sys.argv[2],sleep_time=sys.argv[3]): while true: try: = oanda.get_history() if (something): print("niceeee") else: print("ok cool") except: sleep(sleep_time) if __name__ == "__main__": executor = processpoolexecutor(2) loop = asyncio.get_event_loop() asyncio.async(loop.run_in_executor(executor, meatandpotatoes)) scriptname = str(sys.argv[1] + "/" + sys.argv[2] + "/") asyncio.async(loop.run_in_executor(executor, fmc.heartbeatfunction(

we have work done within thread run on server web app using spring boot . what want happen is: 1) work submitted our custom runnable object 2) work completes when gets turn (it's database operation, , don't need return value except perhaps returning "success" if run() completed without exceptions) however, in our junit tests, seems tasks submitted executorservice or completionservice disappear when main thread finished, unless call take() every time add new task (since blocks until task finished, makes tasks run sequentially, defeats purpose) or if maintain list of futures , call method loop through list , get() value of each feature. the latter option don't think ideal because server application, have requests coming in different users , don't know how detect when should clearing out list of futures. why threads silently disappear , way around this? don't run code async: test runnable directly: @test public void test() { runnab

i'm trying write multithreaded application , need send http.incomingmessage , http.serverresponse objects child process created using child_process.fork(). there way so? edit more info do: i'm writing server application manage 'vhosts'. each vhost has own worker process, when server app receives http request, transfers corresponding vhost process. can't find way transfer underlying http.incomingmessage , http.serverresponse objects.

i did research division 0 error in php. found couple of of them said if statement did code below, still getting error, can tell me what's wrong code? <?php $result = array( 'price' => 0, 'special' => 80 ); $product = array( 'savings' => round((($result['price'] - $result['special'])/$result['price'])*100, 0) ); if ($result['price'] == 0) { echo $result['price']; } else { echo "you save " . $product['savings'] ."%"; } ?> i tried both if == 0 , if != 0 as new php, won't if statement mean if price of product = 0 echo out price , if it's not echo out special price? i'm not allowed move $product array. this seems make more sense, money-wise: check first if price higher special, , if so, perform calculation. $product = array( 'savings' => ($result['price'] > $result['special'] ?

i heard apps use private frameworks can not submitted apple's app store. so, clear new ios programming (have never submitted app approval yet), wondering: 1) difference between third party framework , private framework? 2) parse private or 3rd party? thanks 1) difference between third party framework , private framework? third party framework written developer with ios sdk packet features not need rewrite it.for example afnetworking,it more easy write code network private framework api not in public ios sdk . 2) parse private or 3rd party? parse acts backend of app. ios sdk third party sdk.

in fact, smt-lib standard have rational (not real) sort? going website , not. if x rational , have constraint x^2 = 2, should ``unsatisfiable''. closest encoding constraint following: ;;(set-logic qf_nra) ;; intentionally commented out (declare-const x real) (assert (= (* x x) 2.0)) (check-sat) (get-model) for z3 returns solution, there solution (irrational) in reals. understand z3 has own rational library, uses, instance, when solving qf_lra constraints using adaptation of simplex algorithm. on related note, there smt solver supports rationals @ input level? i'm sure it's possible define rational sort using 2 integers suggested nikolaj -- interested see that. might easier use real sort, , time want rational, assert it's equal ratio of 2 ints. example: (set-option :pp.decimal true) (declare-const x real) (declare-const p int) (declare-const q int) (assert (> q 0)) (assert (= x (/ p q))) (assert (= x 0.5)) (check-sat) (get-value (x

my basic spring mvc web application doesn't work. created simple spring web maven project , deleted unnecessary code simplify it. then, added controller implementation , annotated in book have read recently. deployed sample application book , app have created. sample app works - mine not. when try acces url ...localhost.../app-name/start/basic/show tomcat server shows 404 error. there's code: basiccontroller in spring.app package @controller @requestmapping("/basic") public class basiccontroller{ @requestmapping("/show") public modelandview handlerequest(httpservletrequest arg0, httpservletresponse arg1) throws exception { map < string, string > modeldata = new hashmap < string, string >(); modeldata.put("message", "hello world!"); return new modelandview("showmessage", modeldata); } } app/src/main/webapp/web-inf/mvc-config.xml file: <?xml version=&qu

we developing project lot of functionality , module (call, chat, update feed , on). it's deployment target 7.0 latest. project has been developing since 2013. there lot of bugs , old code. project completed , ready release in app store. but finding difficulties while testing qa. ios changes many things according it's version. struggling check these changes in different versions. for example ios 8.3 facebook sharing have implemented own sdk. old slcomposeviewcontroller no more good. have take care of ios 8.3. i wondering if somehow can list of these ios versions apple make changes, easier check project installing ios version in iphone. think type of information find in developer site. if kind of information helpful us. thanks lot in advance. i asked similar question couple years ago (not saying duplicate!), , got - "read documentation carefully". unfortunately still remains true now, can tools out. for external libraries, recommend using eithe
