Hi, Steve! On Oct 28, Steve Ellcey wrote:
While working on MariaDB on HP-UX we noticed an inconsistency involving the type of enum arguments.
In init_variables and init_one_value (mysys/my_getopt.c), ENUM options are treated as unsigned longs but the enum arguments are actually declared as uint instead of ulong. While this doesn't matter in 32 bit mode when int's and longs's are the same size, it can cause problems in 64 bit mode when long's are 64 bits and int's 32 bits.
We found 4 variables that we think should be ulong instead of uint:
plugin_maturity plugin_maturity_map thread_handling delay_key_write_options
Yes. In 5.5 I've added an assert: DBUG_ASSERT(size == sizeof(ulong)); to Sys_var_enum class (5.5 has slightly different syntax for defining variables). So in 5.5 all these variables are already ulong. Regards, Sergei
