Installation fails in db:migrate with Finnish locale

bug
1

I’m following the INSTALL-cloud.md instructions, using a 1GB DigitalOcean droplet. When I set the values in app.yml to the recommended settings and keep the default English locale, the installation works. When I change LANG to fi_FI.UTF-8 and DISCOURSE_DEFAULT_LOCALE to fi the installation fails. There are some errors from perl about the locale being missing, but while adding the relevant localegen command to the postgres template removes these errors, it doesn’t help with the failure. There’s an error message starting with ERROR: relation "users" does not exist but I get that with the English locale too, so it’s probably not the problem.

The final lines of output are

How could I debug this further?

The error message is saying that

is an invalid topic title.

Looks a bit short to me. What is the English equivalent of that topic title?

This is apparently a translation of “About the %{category} category” into “Alueesta %{category}”. Finnish can be concise that way.

Oh! I’m actually getting a localized database error: “Title ei kelpaa; yritä olla kuvailevampi” means “Title is invalid; try to be a little more descriptive.” I initially thought that’s part of the data, but it’s the actual error message.

As a native Finn, let me I assure you that “Alueesta” is a perfectly good translation of “About the category”. “Alue” means things like region and area, and it’s a common metaphor for more abstract categories. The word “about” is translated to the “-sta” suffix, and there is no determiner like “the”. I might have preferred “Meta-alueesta” to “Alueesta Meta”, but the orthography of that can get complicated if you allow arbitrary text in the category name.

Which means that the title entropy & length requirements need to be reduced for Finnish, and it needs to happen before the categories are seeded.

Thanks for the pointer! Apparently “entropy” means the number of distinct characters, which is not how my statistics teacher would define it, but it’s used as just a label for the property of the title not being something like “abababababab”. I could get a Discourse site up in Finnish with these changes:

I’m not sure that the locale-gen line is critical, but it suppressed a lot of warnings from perl. The git checkout looks like an oversight in the script: it retrieves origin/$version (where $version is something like tests-passed) but then checks out the local $version without merging in the latest changes. The locale-gen and perl commands are really quick-and-dirty modifications; you folks probably have some better ways of doing that.

We need a proper fix here, there are quite a few settings that need to be changed in various locales. I am moving this to bug so we can track it.

Our site setting file needs to allow us to specify different defaults for different locales. Something like

min_topic_title_length:
    client: true
    default: 15
    fi_FI_default: 5

This issue also hurts us in Chinese

I believe this has been fixed.
