I tried forking the symfony to fix a bug but couldn't push the changes. An entity generates the following SQL with the doctrine:schema:update command for mariaDB and yields errors.

CREATE TABLE purchase (id INT AUTO_INCREMENT NOT NULL, requisition LONGTEXT NOT NULL COMMENT '(DC2Type:json_array)', purchase_order LONGTEXT NOT NULL COMMENT '(DC2Type:json_array)', invoice LONGTEXT NOT NULL COMMENT '(DC2Type:json_array)', status SMALLINT NOT NULL, remarks LONGTEXT NOT NULL, UNIQUE INDEX UNIQ_6117D13B15E142BE (requisition), UNIQUE INDEX UNIQ_6117D13B21E210B2 (purchase_order), UNIQUE INDEX UNIQ_6117D13B90651744 (invoice), PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE = InnoDB'

The above yields error at: In AbstractMySQLDriver.php line 115 In PDOConnection.php line 106 In PDOConnection.php line 104

SQLSTATE[42000]: Syntax error or access violation: 1170 BLOB/TEXT column 'requisition' used in key specification without a key length

The correct SQL statement would have been: CREATE TABLE purchase (id INT AUTO_INCREMENT NOT NULL, requisition LONGTEXT NOT NULL COMMENT '(DC2Type:json_array)', purchase_order LONGTEXT NOT NULL COMMENT '(DC2Type:json_array)', invoice LONGTEXT NOT NULL COMMENT '(DC2Type:json_array)', status SMALLINT NOT NULL, remarks LONGTEXT NOT NULL, UNIQUE INDEX UNIQ_6117D13B15E142BE (requisition(128)), UNIQUE INDEX UNIQ_6117D13B21E210B2 (purchase_order(128)), UNIQUE INDEX UNIQ_6117D13B90651744 (invoice(128)), PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE = InnoDB

@Anirban Chakraborty: You'll get better support through one of our support channels: http://symfony.com/support.

Are the connected Bundles also being upgraded by their respective maintainers? e.g. SonataAdminBundle, FosUserBundle, Doctrine, KNP*...

Kindly share, If you have keep an eye on their development or if you know of any resource that will help me keep track.

Best of luck for Symfony 3.4^ & 4.0^ from Pakistan 🇵🇰

@Anirban Chakraborty: MariaDB is not fully supported by Doctrine and the Doctrine Migrations bundle. MySQL 5.7 is a better choice for Symfony Applications ;)
