This adds compatibility with DBAL 4 (ignoring ORM 3 for now).

so previously this skipped any server version and for mysql for example just returned MySQLPlatform.

We could use $connection->getDatabasePlatform() but it would mean we auto-detect the server version which could mean we actually connect to the database. We should avoid that here I guess.

Is there any other way to do this with DBAL 4 except for using a StaticServerVersionProvider with a fallback to an empty server version? 🙈 🤔

@derrabus maybe you have an idea

Why though? For MySQL drivers especially, this sounds like a bad idea because we need the server version to determine whether we talk to a MySQL or a MariaDB.

We check if its a "Mysql like" platform (AbstractMySQLPlatform) to set the collation option 🤔

See

DoctrineBundle/ConnectionFactory.php

Lines 105 to 127 in b1ff934

$platform = $driver->getDatabasePlatform();
if (! isset($params['charset'])) {
if ($platform instanceof AbstractMySQLPlatform) {
$params['charset'] = 'utf8mb4';
if (isset($params['defaultTableOptions']['collate'])) {
Deprecation::trigger(
'doctrine/doctrine-bundle',
'https://github.com/doctrine/dbal/issues/5214',
'The "collate" default table option is deprecated in favor of "collation" and will be removed in doctrine/doctrine-bundle 3.0. '
);
$params['defaultTableOptions']['collation'] = $params['defaultTableOptions']['collate'];
unset($params['defaultTableOptions']['collate']);
}
if (! isset($params['defaultTableOptions']['collation'])) {
$params['defaultTableOptions']['collation'] = 'utf8mb4_unicode_ci';
}
} else {
$params['charset'] = 'utf8';
}
}

Maybe this isn't even needed anymore on DBAL 4? See doctrine/dbal#5214, doctrine/dbal#5246

I believe AbstractMySQLPlatform only handles collation on 4.0, or?

Hm but we also set a default charset utf8mb4 for those platforms 🤔 We have to keep this I think?

Why not using $connection->getDatabasePlatform() instead, which would automatically use the version provider based on the configuration ?

Or better, using $this->getDatabasePlatform() to have the better error message telling you how to do if you want to be able to instantiate the connection in environments not able to connect yet.

I tried this but it would mean we might connect to the database to determine the platform version (if not specified via config). For example all over the testsuite we would try to connect to some mysql db.

Since this is the initial connection that is replaced further down with changed parameters: we should avoid connecting, or?

@derrabus this one needs rebasing to fix conflicts.

Also, I'd like to release 2.11.0 to have the other new features available. Should I wait for this PR or delay it to 2.12 ?

@stof I'd like to see if we can get ORM 3 support done for 2.11 as well. Can you hold back the release for one more day?
