mysql - Laravel truncating strings with special characters -


i have been working on cms months now, have faced various challenges laravel truncating special characters. had change editor in cms bootstrap wysiwyg ckeditor things got quite better there advance escaping options come it. example able prevent '"' becoming '" causing entire string (paragraph) truncate ever finds such encoding.

however cms user has reason input wide range of characters can safely encoded , kept in database in cases special chars unavoidable. example picking embed website (very allowed) may contain of these characters;

/ = %2f  : = %3a # = %23 % = %25 ? = %3f

when pastes link contains characters or tries hyperlink words contain characters ones above(excluding %2f) string truncated. after doing inspection @ various levels noticed string gets back-end function it's truncated before being saved. don't know if laravel (the parser) or mysql (the database use) truncates these strings. here particular case;

when facebook embed :

is pasted in editor found in database

careful observation show '%2f' replace in string '/' string truncated @ '%3f' supposed replaced '?' or @ least left unchanged.

i know security measures have tweaked front editor alot , think end sanitation should left me (if want) way want. need first know how stop such annoying behavior before getting advice on best practice. strings database way comes without changes. in advance.

trying repeat bug

i create test route route::any('/test', 'indexcontroller@test')->name('test');

then - test action:

public function test(request $request) {     if($request->ismethod('post')) {         $er = \app\entity::create([             'log' => $request->code,         ]);           exit('done');     }      echo "<form method=post>" . csrf_field() .           "<textarea name=code></textarea><input type=submit></form>"; }

results

when submit code, can see unaltered in network tab of browser

enter image description here

then go database , see code unaltered well.

enter image description here

what mean

unfortunally, unable repeat bug presented here. means not laravel transforms code unexpectedly. try check network tab , dd() request vars check them. suppose bug somewhere before sending data via network.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
