Remove end-of-life mongodb versions

[mweinelt]

https://endoflife.date/mongodb

• 3.4, 3.6 and 4.0 are EOL
• 4.0 will go EOL during the 22.11 release

all of the above should be remove before branch-off.

@pacien Do you plan to work on this before the branch-off?

@pacien Do you plan to work on this before the branch-off?

Not personally. Also this depends on #172009.

I want the following gone before the 23.05 branch-off:

• mongodb-3_4
• mongodb-3_6
• mongodb-4_0
• mongodb-4_2 (eol 2023/04/01)

All of these have reached their end of life, and we cannot keep them around

[mweinelt]

Can we bump the mongodb version on unifi and unifi-video to 4.4 at the minimum, ideally 5.0 or 6.0?

I'll have a look at it later on 👍

I can only speak for unifi. The update and restore from mongodb-3_4 to mongodb-4_2 can run without issues. Unfortunately it cannot run from 3_4 to 4_4. So the upgrade from 22.11 to 23.05 will be very bumpy for the users of unifi.
(See #207382 (comment)) . We'll need 3_4 -> 4_2 -> 4_4
I'll prepare something for the release notes, but when we remove mongodb-4_2 there will be a second migration step necessary.
EDIT:
Also, unifi (even the newest version 7) is officially build and tested against mongodb version 3.6, even though it is EOL for some time now

Here we are again, MongoDB 4.4 will go EOL in NixOS 23.11 release.
According to this post, https://community.ui.com/questions/Which-MongoDB-versions-are-supported-by-Unifi-controller/0dd633e5-85d3-44a2-ac16-6fa478b1dcfb — I don't see any hope.

Please inline the MongoDB versions 4.4 inside your expressions if you want to keep using UniFi in nixpkgs.

I tested Unifi Controller 7 and 8 with different MongoDB versions, and:

For Unifi 7:

• Officially it supports up to MongoDB 4.4
• It works with MongoDB 5, but not 6 or 7.
• The limitation seems to be a very old MongoDB driver
• There's a protocol change in MongoDB 6, so it'll not work with this old driver
• MongoDB 5 doesn't have protocol change from 4, so it still work.

For Unifi 8:

• Officially it still supports only up to MongoDB 4.4
• It works with MongoDB 5, 6 and 7
• They have updated their protocol driver to a 2022 version.
• This driver is compatible with MongoDB 6, 7, 8

This means that it should be possible for us to remove MongoDB 4.4. We probably also want to remove unifiLTS, unifi5, unifi6 as well.

Disclaimer: When I say "it works", it means that I tested basic functionalities, I can't guarantee full compatibility.

I've been running unifi 8.1.113 with mongodb 6 for a few weeks now with no issues. Upgraded mongodb 4.4 -> 5.0 -> 6.0 and the database as well in each step.

[wegank]

MongoDB 4.4 has been dropped on master. Existing UniFi 7 and 8 users on the unstable branches, who do not have expressions inlined, will have MongoDB upgraded to 5.0 in the next bumps. Please consult the official upgrade instructions if necessary.

MongoDB 5.0 will go EOL in NixOS 24.05 release, so the same instructions in #195448 (comment) still apply.

[june128]

UniFi Network Application 8.1 and newer now officially support MongoDB up to 7.0.
https://community.ui.com/releases/UniFi-Network-Application-8-1-113/af46fd38-8afe-4cef-8de1-89636b02b52c

[mweinelt]

Support for mongodb 5.0 ends after 2024-10-31 and must be removed for the NixOS 24.11 release.
