MariaDB 10.3 Native JSON Support

[kiler129]

Feature Request

Q	A
New Feature	yes
RFC	no
BC Break	no

Summary

52b4692 disabled JSON support for MariaDB 10.2, since the engine is based on 5.6.

MariaDB 10.3 doesn't have its own platform file, but I think it needs one now to enable native JSON storage.

WDYT?

[morozov]

I think it makes sense. If you're going to file a pull request, please make sure there's a functional test which creates and uses a JSON column. This way, we'll make sure that all platforms which declare JSON as supported actually support it.

with

doctrine/dbal v2.7.1

on

Ver 10.3.8-MariaDB-log for Linux on x86_64 (Source distribution)

I'm seeing similar issues to those previously reported (& solved) for MDB 10.2x here

https://github.com/doctrine/dbal/pull/2825

Particularly, the 'infinite schema updates' and failing

doctrine schema:validate

after a (reported) 'successful'

doctrine schema:update

Other than the common issue of 'MDB 10.3 support', not clear that this is the right place for this.

If so, and it's useful, I can add the details here on request.

Atm, I've no specific functional test, other than a new DB init on a symfony4 project install.

[morozov]

@hal869 please provide the details.

@morozov

On a new SF4 + phpcr project, after package installs,

[lcobucci]

@hal869 and what's the entity mapping? Also, as we always ask, could you try to isolate the issue in a test case?

@lcobucci After our offline chat, working on test case, came across this:

#2985

and related ...

Updated to latest dbal/symfony/mariadb, and explicitly removed the

config/packages/doctrine.yaml
    ....
-   server_version: 'mariadb-10.3.8'
    ....

letting the version returned from mariadb get used.

which seems to do the trick for the :validate,

bin/console doctrine:schema:validate
	Mapping
	-------
	 [OK] The mapping files are correct.

	Database
	--------
	 [OK] The database schema is in sync with the mapping files.

now, to look further downstream ...

@morozov as part of my PR I started to investigate how the MariaDB platform can be improved and faced that MariaDB >= 10.3 still doesn't have native JSON support and it convert this type into LONGTEXT by default.

So the previous PR (#2825) should be compatible with 10.3 version as well.

[stephanvierkant]

What's the status of this feature? What has to be done in order to get native JSON support for MariaDB?

I've tried to test it by creating a platform class (by extending \Doctrine\DBAL\Platforms\MySqlPlatform, but I see that MariaDb1027Platform is final, has no interface and is used \Doctrine\DBAL\Schema\MySqlSchemaManager::_getPortableTableColumnDefinition using a private method. Doesn't seem like a good practice, isn't it? Or am I wrong?

I've never contributed to Doctrine before, but let me know if I can help.

@stephanvierkant all you can see here is the status. There's nothing happening in this regard behind the curtain.

MariaDb1027Platform is final […] Doesn't seem like a good practice, isn't it? Or am I wrong?

It looks like an exception. All other platform classes are not final because they don't have an interface that developers could implement instead of extending the class. Although, in this case, it forces you to contribute the change upstream instead of keeping it to yourself which could be seen as a positive side effect for the community.

I've never contributed to Doctrine before, but let me know if I can help.
