There is a wrapper around the generic function:
const char *
assign_min_error_statement(const char *newval, bool doit, bool
interactive)
{
return(assign_msglvl(&log_min_error_statement,newval,doit,interactive));
}
I would simply define some macros:
#define MSGLVL_MIN_ERR_STMT (1<<0)
#define MSGLVL_MIN_CLI_MSGS (1<<1)
#define MSGLVL_MIN_SVR_MSGS (1<<2)
And assign_msglvl(), having been passed the variable 'caller', determined
by the calling function, will do something like this:
/* everyone has likes debug */
if (strcasecmp(newval, "debug") == 0 &&
caller & (MSGLVL_MIN_ERR_STMT | MSGLVL_MIN_CLI_MSGS | MSGLVL_MIN_SVR_MSGS))
{ if (doit) (*var) = DEBUG1; }
/* ... */
else if (strcasecmp(newval, "fatal") == 0 &&
caller & (MSGLVL_MIN_ERR_STMT | MSGLVL_MIN_SVR_MSGS))
{ if (doit) (*var) = FATAL; }
else if (strcasecmp(newval, "off") == 0 &&
caller & MSGLVL_MIN_ERR_STMT)
{ if (doit) (*var) = MIN_ERR_STMT_OFF; }
Personally, I've never liked coding like this. The reason I merged the
base code for each function was so that the GUC code didn't get uglier as
more minimum-level-of-logging parameters were added. But with the code
above, the bitwise operations and appearance of the
assign_msglvl() routine will suffer the same fate, I'm afraid.
Since the flawed code is now in beta, it will need to be fixed. Do people
like the above solution or should I just revert to having a seperate
function for each GUC variable affected?
