php - Why is the controller executed twice (flashbag, redirectoroute)? -


i have 2 routes /alpha , /beta configured in yml. in alphaaction notice placed in flashbag , redirecttoroute occurs. in betaaction notice in flashbag read.

sometimes 2 notices when try /alpha in browser , 1 notice.

can explain happening, i'm doing wrong.

public function alphaaction() {   $this->get('session')->getflashbag()->add("notice",mt_rand());   return $this->redirecttoroute("beta"); }  public function betaaction() {   $notices= $this->get('session')->getflashbag()->get('notice');       return new response(implode($notices,", ")); }

using add method reproduce issues described. can fixed using set method , not add (or setflash) method. 

public function alphaaction() {   $this->get('session')->getflashbag()->set("notice",mt_rand());   return $this->redirecttoroute("beta"); }  public function betaaction() {   $notices= $this->get('session')->getflashbag()->get('notice');       return new response(implode($notices,", ")); }

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
