set value [ns_config -bool /missing/section missing_parameter true]
if {$value == 1} {
puts "$value is true"
} else {
puts "$value is false"
}
What do you think the above will print out?
The problem is that the programmer could test
the value on 0/1 as well, so more defensive way
is to return canonical value's of 1/0 for
true/false boolean values. The code before
retured whatever the value has been given
(y/Y/true/Yes etc pp) which broke some of our
code (that costed us *hours* to dig it out!!!)
The code was broken at that place definitely.
The change fixed that but broke the integer part...
I will look into that now....
