Debugging Effectively in the Cloud - Felipe Fidelix - Presentation at eZ Conference 2017
- 1. Debugging Effectively in the Cloud eZ Systems Conference, 8th June 2017 Felipe Fidelix, UK Business Development Manager, Platform.sh
- 2. ● Code - the quick, dirty way; ● Code - step-by-step with an IDE and xdebug; ● Code - Profiling ● Process - real-time with strace; ● SQL - real-time; ● HTTP traffic - monitor and manipulate in real time; ● Debug remotely! Debug all the things!
- 3. The quick dirty way - dump() dump($mystuff)
- 4. XDEBUG PHPStorm config - bit.ly/2s9DAT7 (Jetbrains website) Step-by-step with XDebug
- 5. 1(or 2) - Set a Breakpoint 2(or 1) - Set your IDE to start listening 3 - Execute the code Step-by-step with XDebug
- 6. IT WORKS! Also - path mappings Step-by-step with XDebug
- 7. Call stack = frames Step over Step into Step out Watchlist More cool stuff Step-by-step with XDebug
- 8. Step-by-step with XDebug A neat real-time console!
- 9. Optionally setup to only debug when a querystring "XDEBUG_SESSION_START=MYKEY" is present. Or cookie. Xdebug Helper - chrome/firefox extension Step-by-step with XDebug
- 11. Profiling
- 12. Xdebug does the profiling Analysis: KcacheGrind Analysis: WinCacheGrind Analysis: Webgrind (php, composer-based) Analysis: PHPStorm Profiling
- 13. Strace -e to filter syscalls -o to output to file -C for summary -f follows forks Real-time process-tracing
- 16. Continuous Deployment Cloud Hosting
- 17. Great developer automation/ workflow for PHP Amazing performance and reliability for live service Flexible platform for PHP What does Platform.sh do ?
- 18. Clone a byte-for-byte copy of your production site in less than a minute Every git branch has a url Eliminates QA bottlenecks 14x faster human testing and validation Fail proof, predictable deployments Quick bug fixes and security release resolution
- 19. Git-driven infrastructure With a single git push you can deploy an arbitrarily complex cluster (with micro-services, messages queues and the lot.)
- 22. 20-40% better developer productivity 90% Less Ops/DevOps effort 40% faster User Acceptance Testing Measured impact A second generation Platform-as-a-Service specifically designed for modern applications * Based on customer feedback collected in 2015-2016
- 23. … debugging in Platform.sh strace $ strace -p $(pgrep php-fpm) -F -e file -C
- 24. … debugging in Platform.sh PHPDBG
- 25. … debugging in Platform.sh runtime: extensions: - xdebug .platform.app.yaml
- 26. … debugging in Platform.sh ssh -R 9000:localhost:9000 bud3vicgjrrsi-master-7rqtwti@ssh.eu.platform.sh
- 27. … debugging in Platform.sh $ rsync -a {ssh-url}:/tmp/cache* /tmp/ ?XDEBUG_SESSION_START=MYKEY ?XDEBUG_PROFILE Alternatives: Cookie Xdebug helper
- 28. Profiling in Platform.sh runtime: extensions: - name: 'blackfire' configuration: server_id: 'MY_SERVER_ID' server_token: 'MY_SERVER_TOKEN'
- 30. Profiling in Platform.sh platform project:variable:set --no-visible-build php:newrelic.license <your-new-relic-license-key>
- 31. Huge developer productivity gains & general savings Gives them fast time to market for changes Trust the live service to perform well What will it do for your customers ?
