i have php scripts run cronjobs. no classes , few functions. id test script phpunit make sure working appears need rewrite php class, dont want (or know how to). for example if had script , function add 1 , 2 together, <?php $a=1; $b=2 $c=$a+$b; ?> how test $c==3 phpunit? thanks, don for example, don't test $c = 3. but because example little simplistic. variable $c stops existing after script executes. fact exists doesn't matter. want test code does, not how things. i modify example little bit: job.php <?php $a=1; $b=2 echo $a + $b; ?> now have output , behavior. test like: public function testjob() { require('job.php'); $this->expectoutputstring('3'); } phpunit has ability assert against stdout. make sure code outputs expect. tests these types of files check did correct. since php's require statement execute file @ point, can run script , check output. if file has functions, inc

with jquery, how can select , change css style of text elements inside table cells contain disabled "input" and/or "select" elements? i need iterate on cells in table, see if there disabled "input" and/or "select" elements in there, , if case, text in particular cell should "dimmed" setting css property opacity=0.5. the solution must work in reasonably modern browsers. use jquery :has() , :disabled pseudo-selectors on td elements: $('td:has(:disabled)').css('opacity', .5); if need more specific disabled elements (probably not needed), use :input ( :input covers both select , input): $('td:has(:input:disabled)').css('opacity', .5);

i'd take user input (like ip address) , split parts separate variables for example 255.255.255.0 now, split string decimal points , save each part own variable. 255 variable1, 2nd 255 variable2, 3rd 255 variable3 , 0 variable 4 integers. how can this? you do: a, b, c, d = input().split(".") the split() method, default, splits string @ each space list. but, if add optional argument, split string character/string. can read more @ official documentation you can check make sure input in proper ipv4 format. if re.match("\d+[.]\d+[.]\d+[.]\d+", input()): print("ipv4 format")

i'm working on project , decided best way implement functionality wanted override method. @ time didn't realize javascript had no notion of calling super() started doing research. i found article ( http://blog.salsify.com/engineering/super-methods-in-javascript ) describes several methods of calling super methods. i wan't super happy ofthose options though , came following. available on fiddle @ https://jsfiddle.net/fpgm8j9n/ . var food = function( name ){ this.name = name; } food.prototype.sayname = function(){ console.log( 'i ' + this.name ); } var fruit = function( name, color ){ food.call( this, name ); this.color = color; this.super = object.getprototypeof( object.getprototypeof( ) ); } fruit.prototype = object.create( food.prototype ); fruit.prototype.sayname = function(){ console.log( 'i fruit , color ' + this.color ); } var orange = new fruit( 'apple', 'red' ); // runs overridden method in oran

i have relation r{id, building, floor, sequence, capacity} where: (building,floor,sequence) -> id id -> (building,floor,sequence) (building,floor,sequence) -> capacity id -> capacity it seems doesn't violate normal form. however, ok id depend on (building,floor,sequence) , vice versa though id primary key? if no, can done? in relation multiple candidate keys, there'll inevitably cyclic dependencies between them - since candidate key can uniquely identify each tuple , each tuple has value each candidate key. the fact 1 key selected being "more equal" others , named primary key irrelevant. (when we're talking abstractly, here. database products may have features indeed make primary key "more equal" alternate keys)

edit i've tried hashmap multiple values under same key , , hashmap looks hashmap<string, list<place>> placemap = new hashmap<>(); also tried put object instead of place(place superclass). when create subclasses , wants add them hashmap get: the method put(string, list) in type hashmap<string,list<place>> not applicable arguments (string, namedplace) and the method put(string, list) in type hashmap<string,list<place>> not applicable arguments (string, descplace) here adding created error: namedplace p = new namedplace(x,y,answer,col,cat); placemap.put(answer, p); descplace dp = new descplace(x,y,answer, desc, col, cat); mp.add(dp); placemap.put(answer, dp); namedplace , descplace both subclasses place, , want them both in same hashmap.. op i'm working on little project here. thing need use hashmap instead of arraylist on part of project because hashmap

the following code works has problem: #include <atomic> #include "windows.h" std::atomic<int> foo; dword winapi baz(void *) { sleep(10000); foo.store(1); return 0;} int main() { foo.store(0); handle h = createthread(null, 0, baz, null, 0, null); while ( !foo.load() ) { sleep(0); } waitforsingleobject(h, infinite); closehandle(h); return 0; } the program uses maximum cpu while waiting. if change sleep(0); sleep(1); uses 0% cpu, worried couple of things: this introduces unnecessary delay program: waste microseconds if flag set in between polls this might still consuming more system resource necessary, in order wake , call load() every millisecond. is there better way? background: have code working using win32 events wake thread , using waitformultipleobjects , i'm wondering if can use std::atomic flags instead, aim of perhaps making code simpler, faster, and/or more portable. idk how os impleme
