Connector/C fails to read MariaDB 10.6+ binary logs
Hi, I'm using MariaDB Connector/C to 3.3.5 to read binary logs. It works perfectly for MySQL 8.0 and MariaDB 10.5 databases. For MariaDB 10.6 and above, mariadb_rpl_fetch() crashes (!) if the binlog contains XA transactions. Specifically, the function fails when it tries to read event type GTID with this contents: 'XA START X'54584e31',X'',1 GTID 0-1-21'
Please advise Sruli Ganor

Thanks for pointing this out, I believe this should now be fixed.

Not sure I understand what's funny in my contents. Is this an internal MariaDB guys sense of humor?
I believe that Benny was speaking about the footer of our mailing list system that was wrong and that has now been fixed.

Regards,
Let me add that sometimes (mostly in older Connector/C versions) function mariadb_rpl_fetch returns this error when reading XA transactions from MariaDB 10.6+ binary log:
Read next binary log event failed; mariadb_rpl_fetch error 1236 (Failed to replace GTID event with backwards-compatible event: corrupt event.; the first event 'mysql-binlog.000329' at 685, the last event read from 'mysql-binlog.000329' at 1989, the last byte read from 'mysql-bin-changelog.000329' at 2161.)
But normally. in 3.3.5 it crashes with no error.
Thanks
Hi,
could you please file a jira issue (https://jira.mariadb.org/) and attach a binary log which could be used to repeat the problem?
Thanks!
