phpunit - Serialization of 'MongoDB\Driver\Manager' is not allowed (php unit) -


i switched mongodb mongodb\driver\manager. re-wrote persistence class , persistencetest class. worked fine. restarted pc , test failed error message:

phpunit 5.7.21 sebastian bergmann , contributors.  serialization of 'mongodb\driver\manager' not allowed

i simplified problem basic class , classtest.

the class:

class abc {     protected $x;      public function __construct()     {         $driveroptions = [ 'typemap' => [ 'root' => 'array', 'document' => 'array', 'array' => 'array' ] ];         $manager = new \mongodb\driver\manager("mongodb://user7:user777@localhost", [], $driveroptions);         $this->x = new mongodb\database($manager, 'testdb', $driveroptions);         $d = $this->x->{'testcollection'}->find();         foreach ($d $e) var_dump($e);     } } $y = new abc();

the testclass:

class abctest extends phpunit_framework_testcase {     public function test123(){} }

i working on windows php 5.6.30 phpunit 5.7.21 , "mongodb/mongodb": "1.1.2".

any ideas why worked in first place , got error message? , class works, called via apache, delivers content of testcollection without errors or warnings.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
