Install Tool DB Analyzer tries to change all VARCHAR fields
I'm experiencing an issue with DB Migrations in Install Tool - the analyzer complains every time about all
varchar fields. E.g.:
ALTER TABLE `be_groups` CHANGE `title` `title` VARCHAR(50) DEFAULT '' NOT NULL Current value: title VARCHAR(50) DEFAULT '''' NOT NULL COLLATE utf8_unicode_ci ALTER TABLE `be_groups` CHANGE `allowed_languages` `allowed_languages` VARCHAR(255) DEFAULT '' NOT NULL Current value: allowed_languages VARCHAR(255) DEFAULT '''' NOT NULL COLLATE utf8_unicode_ci ALTER TABLE `be_groups` CHANGE `pagetypes_select` `pagetypes_select` VARCHAR(255) DEFAULT '' NOT NULL Current value: pagetypes_select VARCHAR(255) DEFAULT '''' NOT NULL COLLATE utf8_unicode_ci ...
What I've also noticed: the reported DEFAULT value in DB consists of 4 quotes:
'''', while proposed one contains two:
Altering table doesn't change anything, and I'm quite unsure how to fix this.

Same here, I posted it on Stackoverflow: [[https://stackoverflow.com/questions/45737730/typo3-lists-all-tables-in-db-compare-because-of-collate]].
I think it could be the collation, not the quotes.

I was able to reproduce this with 8.7.4 and 8.7.3, and mariadb 10.2.x and 5.x, on clean installs via the Install tool.
My guess is that a strict string comparison of
'''' causes the problem.
I think the serialisation of the 'original' column definition is buggy. Note the following case:
ALTER TABLE `tt_content` CHANGE `table_caption` `table_caption` VARCHAR(255) DEFAULT NULL Current value: table_caption VARCHAR(255) DEFAULT 'NULL' COLLATE utf8_unicode_ci
'NULL' is in quotes here, and most definitely should not be, as
'NULL' are very different things for any SQL server. Some aggressive string escaping maybe?

- Status changed from New to On Hold
MariaDB implemented a change to the Information Schema COLUMNS table which changed the output format compared to the original (Oracle) MySQL: https://jira.mariadb.org/browse/MDEV-13132
There is ongoing work in the upstream Doctrine DBAL repository on how to fix this: https://github.com/doctrine/dbal/pull/2825
At this time TYPO3 is not compatible with MariaDB >= 10.2.7 and given that the fix is happening deeply in the upstream Doctrine DBAL stack there is little we can do to work around it at this point in time.

TYPO3 8.7 has dbal 2.5.10 locked atm.
and installs maximum v2.5.13.
MariaDB 10.2 support came with doctrine/dbal 2.7.0
So this is fixed for master and TYPO3 ^9.3 but not for 8.7.

As PHP 7.0 is EOL by 3 Dec 2018 http://php.net/supported-versions.php, maybe TYPO3 8.7 could raise requirements after that?
This Problem is still present with PHP 7.0 dead for a month now and TYPO3 8.7 still in support for quite some time clinging to the PHP 7.0 requirement doesn't make much sense now.
