Update INSTALL.txt and hook_requirements() etc. with remaining Drupal 11 platform requirements

Not sure if it should be here or in its own issue, but we also need to update hook_requirements() for the various database drivers, and that in turn will require removing gitlab jobs for any newly-unsupported database drivers.

I made a item for 'database drivers' in the parent for the work mentioned in #2. I'd like to keep the database work separate from any generalized INSTALL or README files.

I think this is unblocked now.

Let's do the database hook_requirements() here. We could use a summary of the new requirements in the issue summary so tagging for that.

Update IS and also change component because this is about more than documentation.

Comments and title mention a hook_requirements() change also.

INSTALL.txt looks correct though based on the database ticket.

I did not find any hook_requirements that needed a change.

It's not a hook_requirements but believe Drupal\mysql\Driver\Database\mysql\Install\Tasks has to be updated too right?

The issue for mysql did not discuss MYSQLND or libmysqlclient so those still need to be done.

We haven't changed MYSQLND_MINIMUM_VERSION or LIBMYSQLCLIENT_MINIMUM_VERSION since 2015 when they were introduced afaict, probably worth a follow-up task to discuss whether to bump them, whether they're still needed at all etc. but don't need to touch here I think.

This looks good to me.

Made a followup to discuss the 2 constants in #14. #3437786: Remove MYSQLND_MINIMUM_VERSION and LIBMYSQLCLIENT_MINIMUM_VERSION checks

We need to remove some GitLab CI jobs that are now incompatible:

'PHP 8.3 MySQL 5.7':
'PHP 8.3 MariaDB 10.3.22':
'PHP 8.3 PostgreSQL 14.1':
'PHP 8.3 PostgreSQL 15':
'[Commit] PHP 8.3 MySQL 5.7':
'[Daily] PHP 8.3 MariaDB 10.3.22':

Also, there is a build test failure:

    1) Drupal\BuildTests\TestSiteApplication\InstallTest::testInstall
    Failed asserting that a string is not empty.
    
    /builds/project/drupal/vendor/phpunit/phpunit/src/Framework/Constraint/Constraint.php:121
    /builds/project/drupal/vendor/phpunit/phpunit/src/Framework/Constraint/Constraint.php:55
    /builds/project/drupal/core/tests/Drupal/BuildTests/TestSiteApplication/InstallTest.php:40

I am pretty sure the failure is due to #3420972: Add testing wtih SQLite 3.45

The PR looks good to me.
All the minimum database versions have been correctly updated.
For me it is RTBC.

It might be good to change INSTALL.txt to INSTALL.md, which would improve the readability of the file from the repository page.

@Maks Oleksyuk, that work it outside the scope of this issue and as far as I know there is no agreement yet in the community to convert the all .txt files. You can learn more about this topic in the scope guidelines in the Drupal wiki. Cheers.

Added a comment to the MR - if it is just a case of applying the suggestion then we can set this back to RTBC.

Also how lovely is it to adjust the CI in the same issue that adjusted the requirements... gitlabci ftw!

We need to update MySQL 5.7 documentation links in:

• core/assets/scaffold/files/default.settings.php
• core/modules/migrate/src/Plugin/migrate/source/SqlBase.php
• core/modules/mysql/src/Driver/Database/mysql/Connection.php

More tasks:

• We need to remove support for the deprecated modes in \Drupal\mysql\Driver\Database\mysql\Connection::__construct
• \Drupal\Tests\mysql\Functional\InstallerIsolationLevelExistingSettingsTest::testInstaller needs adjusting because we no longer support MySQL 5.7
• \Drupal\Tests\mysql\Functional\InstallerIsolationLevelNoDatabaseSettingsTest::testInstaller needs adjusting because we no longer support MySQL 5.7
• We should probably adjust \Drupal\Tests\mysql\Unit\ConnectionTest::providerVersionAndIsMariaDb to remove unsupported MySQL versions and add MySQL 8 version strings
• We should adjust mysql_requirements() because we don't support MySQL 5.7
• We should have a look at the comment in \Drupal\path_alias\PathAliasStorageSchema::getEntitySchema() - maybe it is not specific to MySQL 5.7 - I think this probably deserves it's own followup.

\Drupal\mysql\Driver\Database\mysql\Connection::__construct : Changes made but not sure they are correct.

Todo:
\Drupal\Tests\mysql\Unit\ConnectionTest::providerVersionAndIsMariaDb : should also update the MariaDB strings?
We should have a look at the comment in \Drupal\path_alias\PathAliasStorageSchema::getEntitySchema() - maybe it is not specific to MySQL 5.7 - I think this probably deserves it's own followup.

I ran the previous commit on the MR against MariaDB which didn't use the different properties to get the transaction isolation level - it was v broken... https://git.drupalcode.org/project/drupal/-/pipelines/163687

Gonna run the new MR against Maria too.

this looks great - green on maria now. We need to create a follow up issue about 11.1.1 mariadb and the transaction isolation level query.

sqlite already has const SQLITE_MINIMUM_VERSION = '3.45'; and pgsql already had 16, it was just MySQL not updated (likely due to gitlab not having all the right versions when we made the decision).

I made one commit to update a docs link for pgsql, moving back to RTBC.

Committed and pushed c8e201a167 to 11.x and a86a0294fb to 11.0.x. Thanks!
