Swift XCTest and asserts -

-

i'm using swift2.

assume have function:

func divide(x x:int, y:int) -> double? {     assert(y != 0)      if (y == 0) {         return nil     } else {         return (double(x)/double(y))     } }

for debugging purposes i'd use assert, can see when passes y = 0 in function.

i'd have workaround in production (i don't want crash, notify user), cannot divide 0. have test:

let res = divide(5, 0) xctassert(res == nil)

but instead of finishing test exc_bad_access on assert in divide function.

can disable asserts somehow tests?

one option add default parameter function used bypass assert:

func divide(x x:int, y:int, safe:bool=true) -> double? {     if safe {         assert(y != 0)     }      if (y == 0) {         return nil     } else {         return (double(x)/double(y))     } }

in app continue call x , y parameters

divide(5, 0)

and assert.

in test call safe parameter false bypass assert , allow use xctassert on result:

let res = divide(5, 0, false) xctassert(res == nil)

i try , create radar chart using chart.js has various colours each scaleline, or coloured between scalelines. wondering if possible? from: to: i have working graph, though there doesn't seem method change individual scale lines. kind regards leigh you can extend radar chart type this, so chart.types.radar.extend({ name: "radaralt", initialize: function (data) { chart.types.radar.prototype.initialize.apply(this, arguments); var originalscaledraw = this.scale.draw; var ctx = this.chart.ctx; this.scale.draw = function () { var linewidth = this.linewidth; // bypasses line drawing in originalscaledraw this.linewidth = linewidth; originalscaledraw.apply(this, arguments); ctx.linewidth = this.linewidth; var scale = this; // draw chart.helpers.each(scale.ylabels, function (label, index) { // color of ...

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
