Author Topic: Upgrade to 4.2 instructions: "Php settings overrides have changed" warning (Read 490 times)

Hi, while reading the upgrade instructions at wiki.civicrm.org/confluence/display/CRMDOC42/Upgrade+Drupal+Sites+to+4.2+-+Drupal+7 (HEY! this forum doesn't allow to post links to wiki.civicrm.org!) I'm quite puzzled by the "Php settings overrides have changed" warning section.

1. The section doesn't mention the civicrm.settings.php file explicitly

2. The section doesn't explain WHAT the user should do about this. One could be tempted to change all the define(...) statements in civicrm.settings.php to the new format, which I believe is NOT needed.

Can anyone please explain what exactly the user should check (and fix) in civicrm.settings.php wrt to this issue?

@cri,

Settings are generally stored in the database. That's where they're most easily tracked and maintained.

But if you have a development environment, it can be tedious when you take a copy of your production data, and then have to tailor the settings for development.

Much easier to place the override settings in the civicrm.settings.php file on the development server.

Check out CRM/Core/BAO/Setting.php. The global variable $civicrm_setting is tested in getOverride() which is in turn called from getItem() before looking at either the cache or the database.

Yes, it's a little bit vague in the documentation, but the mechanism is designed for developers, and is optional anyway. I'll try and clarify the documentation page.

Ok, thanks for your explanation! (yes maybe adding it to the wiki page is a good idea)
