Readd the same workaround as in r1665, for binary collation in SHOW results (MySQL bug #10491 ).

BINARY_FLAG seems broken for fields of a utf8_bin table. Instead use the charset nr returned by a PMYSQL_FIELD. Fixes issue #1479

Treat + decode incoming data as Latin1 if Utf-8 charset is not available, e.g. on old 4.0 servers. Fixes issue #1466 .

Text and Blob data types share the same FIELD_TYPE constants. Makes it necessary to adjust type detection logic.

Reimplement server to server exporting in table tools dialog. This time without the need of having two windows open. Instead, all saved sessions are selectable via pulldown. While exporting we open a temporary connection to the target server - no problem with the new simple database layer. Fixes issue #1434 .

Fix EPrivilege exception ("Privileged instruction"). TMySQLConnection.GetResults() itself frees its result on any exception. Forcing that a second time in a caller per try/finally causes the mentioned exception.

Minor performance tweak: cache data types of all columns once at execution time in TMySQLQuery. Only noticeable in places where we heavily check data types.

Fix potential exception when freeing a TMySQLQuery. A destructor should always call its inherited method at the very end.

Try to fix another unreproducible exception on older servers which fail to SHOW TABLES FROM information_schema. Probably fixes issue #1455 and issue #1439 .

Try a performance optimization: avoid calling mysql_data_seek() in SetRecNo() if not needed - mysql_fetch_row() already does it well enough for successive browsing through records. Only noticable on large results like it's the case when exporting or grid filling.

mysql_store_result() + mysql_free_result() are needed for all result queries, in order to unblock the connection. Fixes disconnecting + reconnect in query editor with multiple SELECT queries.

Fix access violations on old servers, fixes issue #1417 :
...
a) On a 4.0 server, mysql_real_query("SHOW TABLES FROM nonexistant_db") returns 0/OK . A 5.x server returns 1. On 4.0 servers mysql_num_rows() then causes an access violation. So, we now gracefully avoid calling it when mysql_store_result() returned nil.
b) Various hardcoded queries like SHOW ENGINES need to be quiet in any error case.

Implement a more lightweight connection layer, consisting of 2 units in source directory. Breaks threading and window to window communication, which should be reimplemented later.
