  • Seems like at least _LINE_ is needed as input to the function.
  • There is no problem with php5 - I'm using PHP Version 5.2.6 and it works perfectly.
  • clone is working

so - when you are ready...

So if i understand well :

1) This is a major change => we cannot include it just now as phpgw is in freeze-before-release status : OK that makes sense

2) There are technical issues (things we need to have like __clone() and __destruct(), php5 compatibility...) : OK that just need some work to be done, doesn't it ?

3) As this is a major change we'll have to check for side effects and then a large code review will be needed : OK that make sense too

=> Seems in a good way to me

I'll just use it for my self then ;)

You are welcome to use it when you are ready.

It's not copied and pasted from any "All Rights Reserved" licensed site. Inspired by: yes - copied : no

Thanks for the comment on $line and $file

This code isn't in a state that can be used, for the following reasons:

  • trunk is currently being stabilised for a release

  • It drops important functionality like __clone() and __destruct()

  • The "test" code bears no relationship to real world phpgw operations so the stated performance claims can't be verified.

  • There are bigger issues with the db abstraction layer than using PDO or not.  These issues should be addressed in a thorough review of the db code

  • The code is tainted as it has been copied and pasted from an "All Rights Reserved" licensed site - as acknowledged in the initial comment

  • $line and $file aren't needed when calling query as the error handler gets this information anyway

  • It is pretty easy to switch to PDO while still using ADOdb.

  • The code needs to be updated for PHP5

  • The list of other changes looks rather light on and incomplete.

  • There are other issues, but I think this list alone justifies postponing it until after the next release.

It is very few changes needed to the code to make it work - basically what is included in the attached pdo.diff

seems promising... how much work would it need to comply with phpgw coding standards ? can we hope to see it included mainstream ?

I have finished the porting from adodb to pdo (except for some meta functions - which still calls adodb).

Have a look

The class is updated to handle prepared prepared statements for insert and select.

The test include test on FETCH_ASSOC and FETCH_BOTH - seems to make no difference in performance (speed)

I did a test on using PDO for db-connection.
The code is based on the current db-class from trunk and the tutorial found at:

Seems like it is about 5 % faster on reading and 20 % faster on writing compared to adodb with eaccelerator.

The class is not 100% complete - but most of it works.

What do you think.
