TYPO3 Core

Here, there is a collision with uid=4 and uid=5 as well as uid=4 and uid=6. They all have the slug 'hallo-2' which would be ok if the language differs, but sys_language_uid=-1 means the record will be shown for all languages

select uid,sys_language_uid,deleted,hidden,slug,title from db.tx_sypetsexampleslug_something;
+-----+------------------+---------+--------+-------------------+---------------------+
| uid | sys_language_uid | deleted | hidden | slug              | title               |
+-----+------------------+---------+--------+-------------------+---------------------+
|   1 |                0 |       0 |      0 | hallo             | hallo               |
|   2 |                0 |       0 |      0 | halloeoe-usw-blah | hallöö usw. blah    |
|   3 |                0 |       0 |      0 | hallo-1           | hallo               |
|   4 |               -1 |       0 |      0 | hallo-2           | hallo               |
|   5 |                6 |       0 |      0 | hallo-2           | hallo               |
|   6 |                0 |       0 |      0 | hallo-2           | hallo               |

Reproduce¶

There is a minimal extension to reproduce issue which works with v12: https://github.com/sypets/sypets_example_slug

1. Use an extension with slug field (e.g. calendarize or sypets_example_slug)
2. Create several records with the same slugs. Create at least one record with sys_language_uid=-1 (you may have to save once and then generate the slug again to create the duplicate)

The problem can be reproduced with news + TYPO3 v11, calendarize and TYPO3 v11 and TYPO3 v12 and the example extension sypets_example_slug.

or check existing content for extensions, e.g.

news (language 0 or -1):

select path_segment,count(*) as c from tx_news_domain_model_news where not hidden and not deleted and (sys_language_uid=0 || sys_language_uid=-1) group by path_segment order by c;

calendarize (language 0 or -1):

select slug,count(*) as c from tx_calendarize_domain_model_event where not hidden and not deleted and (sys_language_uid=0 || sys_language_uid=-1) group by slug order by c;

Versions¶

• reproduced with latest main branch (v12)
• can be reproduced with v11 using EXT:calendarize, see issue: https://github.com/lochmueller/calendarize/issues/731
