Hello,
since a few days, our setup of PMA is broken.
since latest 5.2.1 release.
if i downgrade to 5.2, it's fine.
my setup is
- Server version: 8.4.3 - MySQL Community Server - GPL
- mysql-router in place
- phpmyadmin 5.2.1 as a docker container
i get "Warning in ./libraries/classes/Dbal/DbiMysqli.php#209
mysqli::query(): RSET_HEADER packet additional data length is past 43 bytes the packet size".
strange things to share:
- it's always 43 bytes. whatever the query is
- if i configure PMA to go directly to the backend (RW) cluster member => it's fine
- if i downgrade PMA to 5.2.0 it's fine
- tcpdumping the exchange between pma and router and router and mysql rw server, i'm unable to identify something wrong
- in all case, i'm getting error on the gui, BUT the update is done by the mysql cluster.
- browsing/using PMA is otherwise fine.
complete stack trace is:

error is reproductible all the time
