Magento's `setup:db:status` fails with MySQL 8.0.29
Preconditions and environment
- Magento 2.4.4
- MySQL 8.0.29 and higher --- Server version: 8.0.29-0ubuntu0.20.04.3 (Ubuntu)
Steps to reproduce
- Set up Magento 2.4.4 following the requirements (https://devdocs.magento.com/guides/v2.4/install-gde/system-requirements.html)
- Execute
setup:upgrade
- Execute
setup:db:status
Expected result
Magento should report that the Database is up-to-date
Actual result
-
bin/magento setup:db:status
Declarative Schema is not up to date Run 'setup:upgrade' to update your DB schema and data.
-
bin/magento setup:upgrade
-
bin/magento setup:db:status
Declarative Schema is not up to date Run 'setup:upgrade' to update your DB schema and data.
-
bin/magento setup:db-schema:upgrade
-
bin/magento setup:db:status
Declarative Schema is not up to date Run 'setup:upgrade' to update your DB schema and data.
Additional information
Issue is caused by charset comparison.
Beginning with MySQL 8.0.28, utf8mb3 is also displayed in place of utf8 in columns of Information Schema tables, and in the output of SQL SHOW statements.
Prior to MySQL 8.0.29, instances of utf8mb3 in statements were converted to utf8. In MySQL 8.0.30 and later, the reverse is true, so that in statements such as SHOW CREATE TABLE or SELECT CHARACTER_SET_NAME FROM INFORMATION_SCHEMA.COLUMNS or SELECT COLLATION_NAME FROM INFORMATION_SCHEMA.COLUMNS, users see the character set or collation name prefixed with utf8mb3 or utf8mb3_.
The default table charset is defined in \Magento\Framework\Setup\Declaration\Schema\Dto\Factories\Table::create
Our internal workaround is a plugin which overrides default MySQL charset if no other provided:
<?php
declare(strict_types=1);
namespace SwiftOtter\MysqlCharsetFix\Plugin;
use Magento\Framework\Setup\Declaration\Schema\Dto\Factories\Table;
class OverrideDefaultCharsetPlugin
{
private const DEFAULT_CHARSET = 'utf8mb3';
/**
* @param Table $subject
* @param array $data
* @return array
*/
public function beforeCreate(Table $subject, array $data): array
{
if (!isset($data['charset'])) {
$data['charset'] = self::DEFAULT_CHARSET;
}
return [$data];
}
}
Another possible solution is to override \Magento\Framework\Setup\Declaration\Schema\Dto\Table::getDiffSensitiveParams
parameters, excluding charset
from the list. (Composer patch below)
diff --git a/Setup/Declaration/Schema/Dto/Table.php b/Setup/Declaration/Schema/Dto/Table.php

The mentioned patch results (for me) in an error during setup:install

@zapotocnylubos There are two possible patches - Just use the other one :)
@lbajsarowicz U mean the plugin, right?
Having the same issue, Creating a plugin <plugin name="fix_default_charset" type="Project\Theme\Plugin\OverrideDefaultCharsetPlugin" sortOrder="1"/> Does not fix this issue. After a successful deploy running setup:db:status still shows: Declarative Schema is not up to date
I'm having the same issue. The schema is always not up to date. The \Magento\Framework\Setup\Declaration\Schema\Diff\Diff::$changes
variable always has 400 entries and all of them are related to utf8mb3
.

As a workaround, I'm using the following patch with the cweagans/composer-patches

It solves the problem with changes caused by encodings. I had other issues as well (#36558), so this workaround patch is not guaranteed to fix all issues.
I think this means we need to update the charset in the database to utf8, since that's a reference at the moment for utf8mb3 and will be updated to a reference to utf8mb4. see: https://stackoverflow.com/a/52337457
same for utf8mb3_general_ci that needs to be updated to utf8_general_ci. Or am i wrong? @engcom-November
Closed without an explanation telling why?
Possibly fixed by AC-7469: Add support for MySQL8.0.29 and higher ?
@hostep; I guess some habits are hard to kick. 😉
Hello,
As I can see this issue got fixed in the scope of the internal Jira ticket AC-5970 by the internal team Related commits: https://github.com/magento/magento2/search?q=AC-7469&type=commits
Based on the Jira ticket, the target version is 2.4.6.
Thanks
Hi all,
utf8mb3
character set is actually deprecated on MySQL 8, we should use utfmb4
instead.
https://dev.mysql.com/doc/refman/8.0/en/charset-unicode-sets.html#:~:text=This%20character%20set%20is%20deprecated%20in%20MySQL%208.0%2C%20and%20you%20should%20use%20utfmb4%20instead
@jonathanribas No disagreement - but Magento currently uses utf8mb3 and this issue is about fixing it not recognizing it.
A new issue should be created to move off the deprecated charset
There is already one for utfmb4
support: https://github.com/magento/magento2/pull/35174
