OSM user names shortened for discourse?

nukeador · 2022-03-18T11:12:21.227Z

It seems username longer than 60 can become problematic not only for UI but for the API endpoints

Question about max username length

Looks like username maximum length is 60 characters even if it’s set greater. I tried with settings of 127 and 254 for username lengths… Endpoint: https://{{url}}/admin/groups name:...

Also, usernames under 3 characters can also mess with the DB

Discourse Meta – 30 Nov 19

Is it safe for the site that reducing the minimum username length as 2

No it is not safe as autocomplete 2 character name searches will cripple your database. If you wish to break your site and your database, go for it.

For some reason my username here on discourse is user1 (someone asked me to change that, but I missed that notification. email me: amanda@technomancy.org). Since OSM usernames can change, “syncing” might be complicated.

If you logout and back in then it should force your Discourse name to match the OSM one.

While the database does contain all lengths between 3 and 255 there is no length over 128 with more than 10 users.

There are around 5000 active accounts over 60 characters though, around 1650 over 80 characters, and around 75000 that are only 3 characters. Many of the very long ones may be spam.

Should we play safe and see if there is more demand to increase the length limit here before taking any decisions that might affect the DB or API?

amapanda_ᚐᚋᚐᚅᚇᚐ · 2022-03-18T11:52:42.000Z

I tried that and it didn’t change anything.

I don’t mind if my username is user1. ᴵᵐ ⁿᵘᵐᵇᵉʳ ᵒⁿᵉ

It is good for us on the forum to explore what is and isn’t possible with this software, so we can explain it to others.

Probably the reason is that Discourse detects that your osm username is a combination of unicode characters and defaults to a safe name instead

_i · 2022-03-18T17:30:48.840Z

Hmm another thing seems to be the normalization of the OSM user names. My nick !i! becomes _i1 and the label shows it in the right way. Not nessesary a big issue, but to mention (and it’s autocomplete) rely on the (slightly wrong) discourse nickname.

nukeador · 2022-03-18T18:29:06.260Z

That seems related with no special characters as part of the nickname.

I keep surprising myself about how osm.org is so permissive with nicknames and that hasn’t resulted in major issues with the DB, APIs or external apps

it must be said that Amanda’s username is… special

Hmm, that’s not ideal for a global audience. Imagine your Chinese user name ends up as “user2”: https://community.openstreetmap.org/u/user2/summary

It seems there are a few options for whitelisting some unicode characters and a warning about not going too broad:

Discourse Meta – 14 May 19

Unicode usernames and group names

Lifting the restrictions on allowed characters in usernames is one of the oldest feature requests. Starting with Discourse 2.3.0.beta9 it’s finally possible to use Unicode characters within usernames and group names. New Site Settings There are...

Is the problem with user names longer than 20 characters solved in meantime or will OSM names longer than that still be cut down to 20 when registrating here?

nukeador · 2022-04-06T17:58:50.297Z

@Firefishy what’s your recommendation here?

Map_HeRo · 2022-04-15T10:42:20.599Z

@Firefishy
Any news regarding this issue …??.. sorry to bother you but I believe it would be helpful if every interested user would be able to register with their OSM name and not only those with names shorter than 20 characters and not containing certain unicode.

trial · 2022-04-24T19:28:37.217Z

You aren’t fluent in Ogham script, really?

Firefishy · 2022-04-27T15:44:50.844Z

I am unsure what the solution is. The restriction are built into discourse and are unlikely to be easy to override.

_i · 2022-04-27T16:00:43.000Z

Not sure if it’s to much attention, but could we inform affected users before they signup to avoid confusion or shitstorm?

mmd · 2022-04-27T18:39:42.554Z

We can change those default values in the settings. This includes extending the range of permitted unicode chars:

Map_HeRo · 2022-04-27T18:41:12.253Z

Thanks for your feedback. I am not sure about the possible maxlength, ist it 20 characters (which appears to be the default) or 60 as mentioned by nukeador in #5?

If there is no way to establish a more flexible name handling, I would support the suggestion of _i1 to inform affected OSM users if that would be possible …

Firefishy · 2022-04-28T08:48:59.068Z

I have now increased max length from 20 → 40 and enabled Unicode. Unicode usernames were not allowed before.
