Can't Run

    Hi,
    I'm really new to fuelPHP, I'm currently checking out the migrations and the Oil tool. I have done test migrations in the past with no issues (version 1.2.1), I just got the latest version of Fuel last night (version 1.3) and I now get this error messages:
    # oil r migrate

    I have updated my /app/config/development/db.php and /app/config/production/db.php files. I'm really stuck, not sure if is a bug in the new version or if there is something I'm missing. I'm starting with a new project from scratch using oil:
    oil create fuel-blog
cd fuel-blog/
oil g scaffold post title:varchar[255] description:text content:text
oil refine migrate
or 
oil r migrate
    Any help is appreciated. Onema

    Please create an issue for this at http://github.com/fuel/core/issues so someone can have a look at it. Your PHP is probably compiled with the mysqlnd driver, which does not support compression. As a workaround you can simply comment line 83 in the pdo connection driver.
  • onemaonema
    Cool,
    I'll do, BTW my version of php:
    PHP 5.3.8 (cli) (built: Dec 5 2011 21:24:09)
  • HarroHarro
    fixed here: https://github.com/fuel/core/commit/250482b2758ee54955bc63af3abc84c2eec8950a. Issue is no longer needed...

    I'm now getting this error message after I updated the file.

  • HarroHarro
    That is odd, according to the PHP manual it's perfectly fine to use defined() to check for existence of a class constant. Do you have compression enabled in your db config? If not, it shouldn't even get to the original line in the first place. Can you check if you got mysqlnd compiled in instead of mysql?
  • onemaonema
    I have not turned on compression, if it is on my default I couldn't find where to set it. I looked in app/config/development/db.php, production/db.php, and db.php. There is no reference to compression there.
  • HarroHarro
    Even more odd. If in that code in connection.php $compress == false, it will not even go into the if() that uses the constant. To solve your issue just remove that if(), if you don't use compression it's not needed. I'll add an issue for this so it can be looked at. edit: looks like the guy that introduced this code has set the default to true. So if you set "'compress' => false" in the connection definition of your db.php it should be solved too.
  • mgabrielromgabrielro
    I was having the same problem 5 minutes ago. I commented the if() and now it works for me.
  • HarroHarro
    It's been fixed for 1.4/develop ( see https://github.com/fuel/core/commit/350234f2855351a24a8d126f1476aa64061a6a6f ). You can port the driver back to your 1.3 installation if needed.

    There is no need to comment out anything, just set
    $compress == false

    Like Harro said and you should be good to go.
    Thanks Harro for taking care of this.
