Previously this kinda worked out due to the first member of field_blob kinda making sense in this comparison. Instead, we just shortcut to that decision if we are converting from BLOB. 1267.1.6: Stewart Smith 2010-11-08 change cast in field_conv.cc that was producing valgrind warning to dynamic_cast to crash on invalid cast. this shows up in several tests: e.g. func_gconcat 1267.1.5: Stewart Smith 2010-11-07 [merge] merge trunk 1267.1.4: Stewart Smith 2009-12-09 remove last bits of packlength from Field_blob, leaving only support for 4 byte length for blobs (not 1, not 2 and certainly not 3). 1267.1.3: Stewart Smith 2009-12-09 remove Field_blob constructor that had set_packflag argument being called in Item::tmp_table_field_from_field_type(). This would cause a Field_blob to be created that used 3 bytes instead of 4 for length... potentially causing all sorts of trouble 1267.1.2: Stewart Smith 2009-12-09 remove Field_blob constructor that only takes packlength as argument. It's never even called 1267.1.1: Stewart Smith 2009-12-09 remove blob_pack_length argument to Field_blob constructor. _______________________________________________ Mailing list: https://launchpad.net/~drizzle-benchmark Post to : [email protected] Unsubscribe : https://launchpad.net/~drizzle-benchmark More help : https://help.launchpad.net/ListHelp
