• Status changed to New if you want to be accepted.
• The priority has shifted from primary to target.
• Target version removed ( next-patchlevel )

• Status from accepted to replaced pending

The finished patch 1 for the master branch of the Packages / TYPO3.CMS project has been moved to the server.
It is available at https://review.typo3.org/29811

AdditionalConfiguration.php:
[…]

require_once from T3Configuration.php is false. Just ask about it here!

• Status changed from Pending to Comments Required.

• Status changed from “Comments Required” to “Under Review”.

Patch position 2 for the Branch Master of the Packages / TYPO3.CMS project has been moved to the article server.
It is available at https://review.typo3.org/29811

Ok, this motivates using require instead of require_once. However, there is no point in reloading LocalConfiguration and AdditionalConfiguration, the method used to clear the entire memory cache.

• Modification of the status “Under completion” mustIt must be corrected.
• % complete increased from 0 to 100

For what reasons should you not use the word “must” now?

• Status changed from resolved to closed.

The database settings are listed after the group environment variables.
$ GLOBALS ['TYPO3_CONF_VARS'] ['DB'] ['password'] = getenv ('TYPO3__DATABASE__PASSWORD'); $ GLOBALS ['TYPO3_CONF_VARS'] ['DB'] ['host'] means $ GLOBALS ['TYPO3_CONF_VARS'] ['DB'] ['username'] getenv ('TYPO3__DATABASE__HOST'); = getenv ('TYPO3__DATABASE__USER'); $ GLOBALS ['TYPO3_CONF_VARS'] ['DB'] ['database'] = getenv ('TYPO3__DATABASE__NAME');

Interestingly, the same basic command works like a spell even after the build is complete and the tools run.
