MariaDB sample not working with MariaDB 10.6

Question

MariaDB sample not working with MariaDB 10.6

Closed this issue 3 years ago · 19 comments

I started with the sample docker-compose.yaml from this repo. The current MariaDB image is 10.6.5, but HedgeDoc is unable to connect to it. Possibly related to #47.

This is the file you posted with mariadb pinned to 10.6 and using the mariadb:// driver.
Everything seems to work fine using this config.

EDIT: Also works using mysql:// in the database URI.

Very strange indeed. I can reproduce this on macOS and Linux:

Answer 4 · 2022-01-27T20:26:42.000Z

I tried your docker-compose files on my linux system and they work. 🤔

Answer 5 · 2022-01-27T20:40:24.000Z

Also works on my MBP.

Answer 6 · 2022-01-27T20:42:03.000Z

@agross Do you have some kind of firewall or an unusual network setup that may interfere with the Docker network? Your stack trace containing PacketInputStream.receivePacketBasic and TCP.onStreamRead may point to networking issues.

Answer 7 · 2022-01-27T20:44:01.000Z

Nothing special, just Fedora Linux. I just tried again on a Hetzner server (also Fedora). I also ran tcpdump in the MariaDB container, there are packets flowing between the app and the database.

Answer 8 · 2022-01-27T20:45:29.000Z

What is really strange is that MariaDB 10.5 works.

Answer 9 · 2022-01-27T20:49:28.000Z

Which Linux distribution did you test on?

Answer 10 · 2022-01-27T21:37:09.000Z

I tested on Fedora 35 with Docker 20.10.12

Answer 11 · 2022-01-27T21:48:47.000Z

Same here 🤔

Answer 12 · 2022-02-03T13:46:09.000Z

Can you please post your SSH public keys here or send them to me (agross at therightstuff.de). I'll set up a a server that shows the behavior.

Answer 13 · 2022-02-06T19:53:55.000Z

Hint: You can append .keys to the URL of a GitHub profile to get that user's public keys.

Answer 14 · 2022-02-07T12:08:00.000Z

@ErikMichelson Nice, didn’t know that! Thanks!

@davidmehren @mrdrogdrog I've added your keys to the test server. Please see for yourself:

Answer 15 · 2022-02-10T14:43:32.000Z

Using image: quay.io/hedgedoc/hedgedoc-nightly:debian which prints out the database error, I get
Database cannot be reached. Try 1 of 30. (Error: Encoding not recognized: 'undefined' (searched as: 'undefined'))

Answer 16 · 2022-02-10T14:45:32.000Z

After commenting out the utf8.cnf volume for the maria container, HedgeDoc starts correctly. So there seems to be an issue with the encoding config we provide.

Answer 17 · 2022-02-10T14:59:47.000Z

I can reproduce locally that our config stops working with MariaDB 10.6.

Answer 18 · 2022-02-10T19:04:06.000Z

There is a fix in #287, but I'm not sure if we can merge it, as it will break old MariaDB installations.

Answer 19 · 2022-02-10T19:19:20.000Z

Thank you for your time researching this issue. I'm going to take down the test server now.
