PHP III - Jan 2019

Last Update: 15 Feb 2019

RE: Errors with Expressive Lab using PropulsionSystems module from Apigility:

  • The service manager does contain a "config" service ... but it's case sensitive, with lower-case "c"
  • The class Zend\Hydrator\ObjectProperty has been renamed to Zend\Hydrator\ObjectPropertyHydrator
  • Copied the propulsion.php data generator from apigility.complete/data to expressive.2019/data
  • Entered into /expressive.2019/config/routes.php this line:
$app->get('/api/propulsion-systems[/:id]', FlyingElephantService\Handler\FlyingElephantHandler::class, 'api.propulsion_systems');
  • Otherwise, the errors shown in class were mainly due to compressing the directory structure of PropulsionSystems to get rid of /V1/Rest
  • Code works OK now:
    • Go to the expressive.2019 folder
    • Run composer install
    • Run php -S localhost:8888 -t public
    • From your browser (or REST client) try these tests:
http://localhost:8888/api/propulsion-systems
http://localhost:8888/api/propulsion-systems/01d1c119-bf97-4a05-b5d6-d94d950d049f

RE: Errors with phing and Jenkins

  • Gertjan reported errors when using Jenkins to run phing to deploy
  • Response from Daryl:
    • Doug, it looks like I had inadvertantly lost the orderapp/build, and orderapp/build-JCI directories way back in January 2018. I was able to recover them from the January 9th commit and have attached them here as zip files. These contained the Phing build scripts, without which, the deployment will not work. Have the students put these in the orderapp directory, then double check the Jenkins "OrderAppDeploy" freestyle project, and execute the build again. Let me know if there are any issues. -- Daryl
    • Look in this repo for the /php3/src/ModTargetedServerEnvironments/Deployment folder
    • Copy this directory structure and overwrite the Phing/build and Jenkins/build-JCI folders

How to run the Stratigility demo

  • Change to the Zend/workspaces/DefaultWorkspace/stratigility folder
  • Run the PHP dev server as follows:
php -S localhost:8888 -t public
  • Go to your browser and open this URL: http://localhost:8888
  • Alternatively set the permissions on the log folder so the www-data user has rights to the log file

ERRATA

  • file:///D:/Repos/PHP-Fundamentals-III/Course_Materials/index.html#/3/12: EventManager needs to be rewritten
    • see files in the directory structure /php3/src/ and /php3/src/ModSPL/StandardDatastructures/SplPriorityQueuein the repo for rewrites
  • file:///D:/Repos/PHP-Fundamentals-III/Course_Materials/index.html#/3/42: use the autoloader to avoid the 3rd require statement

  • file:///D:/Repos/PHP-Fundamentals-III/Course_Materials/index.html#/5/43: dir structure changed
    • Look in this repo for the /php3/src/ModTargetedServerEnvironments/Deployment folder
    • Copy this directory structure and overwrite the Phing/build and Jenkins/build-JCI folders
    • Suggestion: just use one user for both labs
    • Troubleshooting tips: i.e. when do you have restart Jenkins, or refresh the browser
  • phing lab:
    • This error should be fixed by copying the files into Phing/build as mentioned just above
    • from Gertjan to Host (privately): error happend at slide 213: phing -f build.xml
