Sentences appear registered under language, but don't show up in "Recent Contributions"

[DJ-Saidez]

This is the list of sentences created in the process of adding language Gun to Tatoeba.
https://tatoeba.org/en/sentences_lists/show/171793
This process is shown in #3085.
When you go to the list, and each individual sentence page, it appears properly registered as a Gun sentence.

But when you go to Recent Contributions and search for sentences in Gun, no sentences come up.

The previously added sentences should be shown here, even if they were initially added under "Unknown language" before Gun was added.

I guess there could be some misunderstanding on how the "latest contributions" page works. That page will only ever show the latest 200 contributions over all the languages of Tatoeba. So when you filter to "latest contributions in Gun", you will only see if any Gun sentence is part of these latest 200 contributions. In other words, it is very easy for mainstream languages to crowd out minor languages from the list of "latest contributions".

Does that explain the issue you are pointing out?

If that were the case, then if I searched for recent contributions in Chavacano (most recent contribution December 2024) then I shouldn't have any sentences show up, but they do. So maybe the mechanism is a little different?

Oh, you’re right! My bad. The 200 latest contributions thing I said earlier is only for the "Currently contributing" block on the right.

That’s a bug (or is it?). Where Gun sentences were initially to their list, they were all marked as "unknown language". As such, the contribution record says that these sentences were of language "unknown". So when you filter the contribution log by language, they don’t show up. In other words, only sentences which language were set to "Gun language" at creation time will show up in the latest contributions.

This also affect any sentence which language was mistakenly detected. For example, I add a sentence in French, I set the language to "autodetect" and it is detected as Italian. Right after, I switch the flag to French and it’s all good. But, my sentence will show up in the "latest contributions in Italian" only, not French.

That issue is worsened by the fact that language changes are not recorded in the contribution logs, which makes the whole thing look even messier than it is.
