<!-- HISTORY of the DRIVER -->
first driver (0.8.4) april 2009
 - used resources and classes (for types code/date/id/regex/bindata only)
 - only very basic crud operations:
   static function_entry mongo_functions[] = {
  PHP_FE( mongo_connect , NULL )
  PHP_FE( mongo_close , NULL )
  PHP_FE( mongo_remove , NULL )
  PHP_FE( mongo_query , NULL )
  PHP_FE( mongo_insert , NULL )
  PHP_FE( mongo_batch_insert , NULL )
  PHP_FE( mongo_update , NULL )
  PHP_FE( mongo_has_next , NULL )
  PHP_FE( mongo_next , NULL )
  PHP_FE( mongo_gridfs_init , NULL )
  PHP_FE( mongo_gridfs_store , NULL )
  PHP_FE( mongo_gridfile_write , NULL )
  {NULL, NULL, NULL}
 - many existing functionality through PHP based classes

<slide>slides/mongodb/driver-history-0.8.4-2.xml</slide>

0.9.0 - 5.3 support (may 2009)
- does db, cursor and collection classes

<slide>slides/mongodb/driver-history-0.9.0.xml</slide>

1.0.0 - sept 2009
- the choice to always return arrays is made

<slide>slides/mongodb/driver-history-1.0.0.xml</slide>
<slide>slides/mongodb/driver-history-1.0.0-2.xml</slide>

nov 2011 - I start helping out
jan 2012 - Hannes does the odd patch
feb 2012 - Kristina retires - 1.2.8
by now, we don't rely on PHP classes at all anymore

<slide>slides/mongodb/driver-history-1.2.8.xml</slide>

jun 2012 - Hannes starts helping out properly
aug 2012 - merge in new connection handling (no more connection pools) 1.3.0alpha1
         - we start using sane branches with git
sep 2012 - jeremy starts doing the odd patches
nov 2012 - 1.3! 

<slide>slides/mongodb/driver-history-1.3.0.xml</slide>

releases now come close to MongoDB server releases

1.4 ssl support may 2013 (2.4)
may 2013 - Jeremy starts helping out properly
1.5 sasl support, command cursors apr 2014 (2.6)
1.6 rewritten cursor support. MONGO_METHOD refactoring / MongoDB 3.0 support jan 2015 (3.0)

<slide>slides/mongodb/driver-history-1.6.0.xml</slide>

That much for history, the current state of the driver is:

- Three guys working on it
- It supports everything up to MongoDB 3.0
- There are some... issues:

  - GridFS
  - Some interesting design choices (array/object output)

<slide>slides/mongodb/driver-current-status.xml</slide>

<!-- NEW GOALS -->

- Easier to maintain
- Easier to prototype
- Support other engines without redoing it all

<slide>slides/mongodb/new-driver-goals.xml</slide>

<!-- THE ENGINES -->
<slide>slides/mongodb/the-engines.xml</slide>

<!-- PHP 5 -->
<slide>slides/mongodb/engines-php5.xml</slide>

<!-- HHVM -->
<slide>slides/mongodb/engines-hhvm.xml</slide>

<!-- PHP 7 -->
<slide>slides/mongodb/engines-php7.xml</slide>


<!-- NEW ARCHITECTURE -->

libbson, libmongoc, Hippo, Phongo and Phplib (flip?)
Other packages on top (GridFS)
Composer

- MongoDB vs Mongo extension

- PHP 7...

<slide>slides/mongodb/phongo-php5-7.xml</slide>

<slide>slides/mongodb/phplib.xml</slide>
<slide>slides/mongodb/phplib-usage-2.xml</slide>

<!-- ISSUES -->

- APIs changing in Phongo meant that things had to be redone for Hippo
- Namespaces for drivers, exception and bson classes

<slide>slides/mongodb/moving-target.xml</slide>

HHVM is not mature, and certainly not documented.

- Slow going, mention the hhvm cookbook
- issues with cursor and foreach iteration

<slide>slides/mongodb/hhvm-maturity.xml</slide>

<!-- CURRENT STATUS -->

Phongo in alpha (0.6.3) 
Hippo in pre-alpha (but you can do all basic ops)
phplib (as mongodb/mongodb) on packagist: https://packagist.org/packages/mongodb/mongodb (0.2.0)
