Fix Error: Could not process the 'wp-config.php' transformation #29800

ribaricplusplus · 2021-03-11T19:47:40Z

Description

This is an addition to #29770

#29770 Seems to fix the access denied error, but then a new error arises described in this comment #29770 (comment)

This PR fixes that error and it should close issue #29752

How has this been tested?

Running wp-env start from an empty directory

I'm not sure that manually changing permissions for wp-config.php is the right fix, see discussion at #29770 😅

I think you have a good point that configuration should be set idiomatically via docker-compose configuration.

However, I think it would still make sense to fix wp-config.php permissions, because currently wp-config.php is owned by root and so any commands that need to use the config for any reason would fail.

Thoughts?

We've had to update permissions for some of these files to get them to work in wp-env before, so I'm not against it

I don't think we should use WORDPRESS_CONFIG_EXTRA because the wordpress image will only use that variable if wp-config.php doesn't already exist which isn't very flexible for developers. For example: you wouldn't be able to update WP_DEBUG in .wp-env.json, restart wp-env, and see WordPress running in debug mode.

I don't think we should use WORDPRESS_CONFIG_EXTRA because the wordpress image will only use that variable if wp-config.php doesn't already exist

I'm not totally sure, but I think that's no longer true per docker-library/wordpress#557, which has wp-config.php read those values dynamically from the docker env (using a getenv() helper); see e.g.

WORDPRESS_DEBUG: https://github.com/docker-library/wordpress/pull/557/files#diff-7f28a0f62019f2d8b061638e8c3aea207404c1499f1c9241db3216fadd8f4530R99 or

Note: I have not run wp-env in several weeks, so my docker image probably wasn't updated at first.

When running npx wp-env start, I first got this issue:

After running npx wp-env start --update, I get the following error:

~/source/gutenberg(fix/wp-env-docker-compose) » npx wp-env start --update                                                                                            noahtallen@Noah-MBP16

ribaricplusplus · 2021-03-11T22:07:41Z

You get that error because the database wordpress that root is trying to connect to doesn't exist. And it doesn't exist because MariaDB image doesn't create a new database as specified in the environment variables if a volume is already mounted.

So if you delete volumes with wp-env destroy and then do wp-env start again, it's going to work.

I don't know if there's anything we can do about this.

noahtallen · 2021-03-11T22:10:28Z

Is this just a one-time problem?

ribaricplusplus · 2021-03-11T22:13:27Z

Because of changes by @youknowriad from #29770 (which this PR extends), the database is always going to be created properly in the future. So it should be a one time problem.

noahtallen · 2021-03-11T22:18:59Z

Login seems to be broken. using root instead of username doesn't work either:

It successfully starts, though!

Note that the PHPunit tests appear to be broken. Seems like we might have to debug the bootstrap file to get more helpful information

ribaricplusplus · 2021-03-11T22:23:02Z

Username: admin
Password: password
Works for me. Those don't work for you?

noahtallen · 2021-03-11T22:32:33Z

Ah, FML, not sure why that slipped my mind! Thanks :)

Looking into the PHPunit stuff now

noahtallen · 2021-03-11T22:36:30Z

Hm. npm run test-unit-php passes locally.

tmdk · 2021-03-11T22:56:59Z

The phpunit container is still missing the WORDPRESS_DB_* environment variables. Tests were failing for me because of this with "wpdie called" as the only output.

noahtallen · 2021-03-11T23:01:49Z

Interesting, I wonder why they passed locally for me in that case. It totally makes sense though.

@ribaricplusplus it might make sense to pull out the wordpress constants into their own object so that we don't have to repeat them everywhere. e.g.:

const databaseEnvironment = {
	WORDPRESS_DB_NAME: 'tests-wordpress',
	WORDPRESS_DB_USER: 'root',
	WORDPRESS_DB_PASSWORD: 'password',
	WORDPRESS_DB_HOST: 'tests-mysql',
};

// later on, in the compose config:
environment: {
  ...databaseEnvironment,
}

noisysocks · 2021-03-11T23:32:59Z

packages/env/lib/build-docker-compose-config.js

 				},
 				volumes: [ 'mysql:/var/lib/mysql' ],
 			},
+			'tests-mysql': {
+				image: 'mariadb',
+				ports: [ '3306' ],


This port is already being used by the mysql container above.

I think those ports just denote which ports are exposed within a container. Ports are isolated within individual containers, so if I'm not mistaken there should be no conflict.

EDIT: According to compose specification this short notation means that the port 3306 inside the container is going to be assigned an ephemeral port on the host machine. Still, that means there should be no trouble.

noisysocks · 2021-03-11T23:34:37Z

packages/env/lib/build-docker-compose-config.js

 				},
 				volumes: [ 'mysql:/var/lib/mysql' ],
 			},
+			'tests-mysql': {


Not a big fan of adding an extra MySQL container. It will mean there's a lot of extra memory usage and startup time.

How about we keep to a single container and create two databases ourselves using wp db create?

https://developer.wordpress.org/cli/commands/db/create/

Could that be a follow-up task? It seems higher effort than the current approach

Yep absolutely.

How about using one database, and different table prefixes for dev and tests, respectively? The wordpress docker image supports a WORDPRESS_TABLE_PREFIX env variable for that purpose.

This reverts commit a982f82.

ribaricplusplus · 2021-03-12T00:17:14Z

@noahtallen Did that with the last commit.

packages/env/lib/build-docker-compose-config.js

noahtallen

Alright, let's merge this now to get everything working. For follow up:

Figure out a better way to consume Docker (perhaps our own docker image, or one of the ones maintained by wordpress) so that we don't run into this issue again.
Move away from a separate tests-mysql, perhaps creating the test DB manually in the installer script.
Resolve anything else that might not be working (unsure if anything else is broken.)
Push this change to npm ASAP.

I'm stepping away soon, so passing the torch on to the next person :)
