1. Mongo HHVM Driver Marco Gentili & Alisa Nguyen May 7, 2014
2. MongoDB Core Classes Overview
3. Quick Refresher on HHVM PHP Interpreter HHVM (JIT Compilation)
4. HHVM has great performance...
5. ...so people want to use it!
6. Wait...why doesn’t the regular PHP Mongo extension work? Straight from the Mongo PHP Team: Our task: Make MongoDB work with HHVM!
7. Our Tasks • Implement all MongoDB core classes within the HHVM extension framework using PHP and the Mongo C Driver via C++ • Create PHP Mongo-specific types ◦ MongoDate, MongoID, MongoTimestamp • Create PHP testing suite for our driver
8. Design Since we want to be transparent (using PHP interpreter vs HHVM shouldn’t be any different), client API needs to be identical
9. Design Cont’d • Main choice: which methods to make native (C++) and which to do in PHP • Decision: Write C++ methods only when absolutely necessary (need to contact DB) ◦ Insert, remove, update, run a query ◦ Benefits: Easier to catch errors, elegant!
10. Cool Code Chunk 1 HHVM only allows one PHP file for Dynamic Extensions...
11. Cool Code Chunk 2
12. Evaluation PHPUnit Testing Framework

14. The Team Jeremy Mikola, Mentor
15. Collaboration • Seven students: PHP Team, C++ Team, BSON Team • One MongoDB mentor: Jeremy • Weekly 1 hr Google Hangout meetings • Consistent IRC availability
16. Future Recommendations For Project: • Clearly defined goals and end-product • Weekly meetings and constant communication • Good kickoff experience
17. Future Recommendations We recommend OpenAcademy for the student who: • is willing to take A LOT of initiative • wants to become very familiar with Git • works well alone
