Hi Georg > Hope this helps! Yes, That's exactly the answer I was looking for. Thanks!
I'll add those mysql symlinks to the libmariadb.so and propose a change in Fedora. (Which should not rise any problem, because of the API & ABI compatibility) While we talk about it, currently, you provide 2 binaries: mysql_config mariadb_config I guess, you plan to remove mysql_config some versions later? Are there any notable (compatibility) differences between them? -- Michal Schorm Associate Software Engineer Core Services - Databases Team Red Hat On Thu, Jun 8, 2017 at 9:12 AM, G R <[email protected]> wrote: > Hi Michal, > > libmariadb.so.2 is MariaDB Connector/C 2.x, while libmariadb.so.3 refers > to MariaDB Connector/C 3.0 (GA will be released together with next MariaDB > 10.2 release in July =10.2.7). > > Both versions are backwards compatible with libmysql.so.18 - API and ABI > wise, unless applications will abuse internals of MYSQL or MYSQL_STMT > structures instead of using API functions (like mysql->reconnect=1 > instead of using mysql_options(mysql, MYSQL_OPT_RECONNECT, &value). > > Connector/C versions < 2.2.2 are not 100% ABI compatible, since the plugin > interface differs (MySQL changed the interface without bumping the > interface number years ago). > > Compared to libmysql.so.18 libmariadb.so.3 offers additional functions and > features: > > Functions: > - mariadb_cancel > - mariadb_connection > - mariadb_get_charset_by_name > - mariadb_stmt_execute_direct > - mariadb_get_charset_by_nr > - mariadb_get_info > - mariadb_get_infov > - mysql_optionsv > > Functionality: > - prepare and execute in one step (mariadb_stmt_execute_direct) > - bulk insert for prepared statements (will be supported in 10.2.7) > - TLS/SSL: > - finger print verification of host certificate > - GnuTLS, Schannel (Windows), OpenSSL or LibreSSL support > - Connection plugins (e.g. for replication/failover, tracing, tunelling > etc.). > - Kerberos authentication plugin > > Hope this helps! > > /Georg > > > > On Wed, Jun 7, 2017 at 4:50 PM, Michal Schorm <[email protected]> wrote: > >> Hello, >> >> I'm currently quite confused about the *libmariadb* library. >> >> In MariaDB 10.1.24 there are: >> " libmysqlclient_r.so -> libmysqlclient.so " >> " libmysqlclient.so -> libmysqlclient.so.18 " >> " libmysqlclient.so.18 -> libmysqlclient.so.18.0.0 " >> " libmysqlclient.so.18.0.0 " >> >> In MariaDB 10.2.6 there are: >> " libmariadb.so -> libmariadb.so.3 " >> >> In MariaDB-connector-c v2.3.3 there are: >> " libmysqlclient.so -> libmariadb.so " >> " libmysqlclient_r.so -> libmariadb.so " >> " libmariadb.so -> libmariadb.so.2 " >> " libmariadb.so.2 " >> >> -- >> >> 1) is "libmariadb.so.2" compatibile with "libmysqlclient.so.18.0.0"?
