This is needed to avoid BOMs with iconv Fixed bug that could cause crash, when iconv returns -1(i.e. could not convert the string), it could be interpreted((size\_t)-1) as very long string length Fixed wrong length calculations when surrogate utf16 pairs involved Added to test framework means to work with widestrings(SQLWCHAR). Changed tests accordingly. * [Revision #94dcdd0](https://github.com/mariadb-corporation/mariadb-connector-odbc/commit/94dcdd0)\ 2015-09-28 19:32:47 +0200 * Merge branch 'master'(1.0) into [ODBC-2](https://jira.mariadb.org/browse/ODBC-2).0 + Version bump(to 2.0.9) * [Revision #97fd947](https://github.com/mariadb-corporation/mariadb-connector-odbc/commit/97fd947)\ 2015-09-24 23:30:08 +0200 * Small changes/additions to ssl.

That is required by ODBC specs "...after it successfully disconnects from the data source, frees those statements and all descriptors that have been explicitly allocated on the connection" * [Revision #2aa408d](https://github.com/mariadb-corporation/mariadb-connector-odbc/commit/2aa408d)\ 2015-02-01 16:07:48 +0100 * Fix of crashes in the DS setup dialog and in freeing explicit descriptor, if statement that used it has been free'd prior to that. Setup dialog crashed after test of connection. The reason was that connection function in driver after successful stored pointer to the DSN structure it used in the DBC object. And setup lib passed pointer to the structure allocated on stack. The patch makes caller decide whether to store DSN pointer or not. Stmt destructor did not check if ard and apd are explicitly allocated, and always free'd them. That lead to the crash when application attempted to free such descriptor afterwards. Also patch contains minor changes such as change of the project name and amendments to couple of testcases. * [Revision #223ec8b](https://github.com/mariadb-corporation/mariadb-connector-odbc/commit/223ec8b)\ 2015-02-07 04:46:33 +0200 * Adding missing FindDM.cmake plus some fixes in linux specific files * [Revision #aaf494e](https://github.com/mariadb-corporation/mariadb-connector-odbc/commit/aaf494e)\ 2015-02-07 02:24:28 +0100 * Stuff for linux - mostly charsets conversion *This page is: Copyright © 2026 MariaDB.
