HHVM for PHP and Hack

Transcript

1. HHVM HACK PHP + + Mariusz Gil
4. BE FAST AT SCALE
13. IS SLOW
14. ISN’T FAST
15. CODE INTERPRET TO OPCODE OPCODE EXECUTION OPCODE CACHE
16. SOLUTION NEEDED
20. SUCCESS 50% CPU USAGE REDUCTION
21. CODE TRANSFORM CODE TO C++ COMPILE WITH G++ EXECUTE NATIVE CODE
22. FAILURE?
25. HHVM OPEN SOURCE VIRTUAL MACHINE FOR PHP
26. HHVM OPEN SOURCE VIRTUAL MACHINE FOR PHP PHP5 SUPPORT* HACK SUPPORT JIT COMPILATION HHVM NATIVE INTERFACE FAST CGI SUPPORT CLI SUPPORT HPHPD
27. CODE TRANSFORM CODE HHBC OPTIMIZE TRANSLATE HHBC TO X86-64 CODE EXECUTE NATIVE CODE
28. cat ./phpversion.php <?php ! var_dump(phpversion()); ! ! php -f ./phpversion.php string(16) "5.5.9-1ubuntu4.4" ! ! hhvm -f ./phpversion.php string(11) "5.6.99-hhvm"
29. cd/var/www/webapp; ! hhvm --mode server -vServer.Type=fastcgi -vServer.FileSocket=/var/run/hhvm/hhvm.sock -vAdminServer.Port=9001 ! ! root /var/www/webapp; fastcgi_pass unix:/var/run/hhvm/hhvm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params;
30. alias composer="hhvm -v ResourceLimit.SocketDefaultTimeout=30 -v Http.SlowQueryThreshold=30000 /usr/local/bin/composer”
31. JIT OPTIMIZATIONS
32. EXTENSIONS API
34. HACK LANGUAGE FOR HHVM THAT INTEROPERATE SEAMLESSLY WITH PHP
35. HACK LANGUAGE FOR HHVM THAT INTEROPERATE SEAMLESSLY WITH PHP TYPE ANNOTATIONS TYPE ALIASING GENERICS NULLABLE TYPES COLLECTIONS CONTINUATIONS LAMBDAS ASYNC PROGRAMMING SHAPES TUPLES
36. <?hh ! class Mailbox<T> { private ?T $data; ! public function __construct() { $this->data = null; } ! public function put(T $mail): void { $this->data = $mail; } ! public function check(): ?T { if ($this->data !== null) { return $this->data; } return null; } }
37. cat ./test.hh <?hh ! function f(): Vector<T> { return 'not an Vector<T>'; } ! ! hh_client /home/vagrant/test.hh:3:22,22: You probably forgot to bind this type parameter right? Add <T> somewhere (after the function name definition, or after the class name) Examples: function foo<T> or class A<T> /home/vagrant/test.hh:4:10,27: Invalid return type /home/vagrant/test.hh:3:15,20: This is an object of type Vector /home/vagrant/test.hh:4:10,27: It is incompatible with a string
38. PHP NG
39. sapi/cli/php -v PHP 7.0.0-dev (cli) (built: Sep 25 2014 22:05:10) Copyright (c) 1997-2014 The PHP Group Zend Engine v2.8.0-dev, Copyright (c) 1998-2014 Zend Technologies
40. CODE TRANSLATE ZEND BYTECODE TO LLVM COMPILE TO MACHINE CODE EXECUTE MACHINE CODE
41. HIPPYVM IS PHP IMPLEMENTATION USING PYPY
42. DEMO
43. 0 0,4 0,8 1,2 1,6 bench heapsort binary trees php 5.5.9 php-ng hhvm
44. SILVER BULLET
45. NOPE! CODE IS NOT YOUR BOTTLENECK, DATABASE AND STORAGES ARE
46. ARCHITECTURE AND CAREFULL PROGRAMMING!
48. NO CODE IS FASTER THAN NO CODE
49. VARNISH
