Bug #99529

Updated by Sybille Peters over 1 year ago

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 

 <pre> 
 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                 |

 h2. 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":https://github.com/sypets/sypets_example_slug) 
 2. Create several records with the same slugs (e.g. use same title if title is used). Create at least one record with sys_language_uid=-1 

 h2. Versions 

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

 <pre><code class="php">
