Hello everybody,

after the release of 10.1.27 upstream was made aware of a regression, so the release has been pulled from the downloads system. The fix will be in 10.1.28. I removed mariadb 10.1.27 packages from [testing].

Thank you Christian - related note - can you share thoughts around 10.2?

We tried to upgrade to MariaDB 10.2.6, which ended in a disaster. The client library has been renamed from libmysqlclient to libmariadb and it has seen structural changes for data types. Programs fail to link or - if they do link - crash or misbehave, including data corruption. I do not see any way to upgrade any time soon. IMHO data structures have to be made opaque in favor of accessing data via functions. OpenSSL suffered a similar problem, which has been solved with version 1.1.0. MariaDB upstream would have to do something similar. -- main(a){char*c=/* Schoene Gruesse */"B?IJj;MEH" "CX:;",b;for(a/* Best regards my address: */=0;b=c[a++];) putchar(b-1/(/* Chris cc -ox -xc - && ./x */b/42*2-3)*42);}

Thanks - so it's clear - are you saying that the recommended method of running[1] mysql_upgrade does not in fact work properly?

No, mysql_upgrade updates the table data (schema 'mysql'), that's not a problem. The server itself works just fine. But API/ABI in library /usr/lib/libmariadb.so and header files in /usr/include/mysql/ changed. Lots of programs break because of this. -- main(a){char*c=/* Schoene Gruesse */"B?IJj;MEH" "CX:;",b;for(a/* Best regards my address: */=0;b=c[a++];) putchar(b-1/(/* Chris cc -ox -xc - && ./x */b/42*2-3)*42);}
