Issue with type based on time.Time

[iampeter]

I have a Date type:

type Date time.Time

The type is used for date-only JSON representation. I AM using a pointer to Date:

type Document struct {
   Created    *Date
}

and MergeWithOverwrite does not work unfortunately.

Could you help with this?

[darccio]

Yes, sure. I'll check it this weekend.

Thanks @imdario

@imdario any luck with this? thanks

[darccio]

No, sorry, I was kinda sick and I didn't have the energy to look at this. I will try this week.

[iampeter]

ok thanks @imdario

I just tested with just *time.Time (no new type) and it seems to 'go deeper' anyway - does not overwrite.

[iampeter]

@imdario, doesn't this:

    case reflect.Ptr:
        fallthrough
    case reflect.Interface:
        if src.IsNil() {
            break
        } else if dst.IsNil() {
            if dst.CanSet() && (overwrite || isEmptyValue(dst)) {
                dst.Set(src)
            }
        } else if err = deepMerge(dst.Elem(), src.Elem(), visited, depth+1, overwrite); err != nil {
            return
        }

mean that if the destination pointer exists, it will try to deep-merge anyway, instead of overwriting the whole struct the pointer points to?

Yes, you are right. "overwrite" should be used with dst.IsNil(). If dst is not nil, as in your case, it won't check if it must overwrite it anyway. Good catch! I modify it, test and push it to master.

[darccio]

A little test and... Ta-da! That little sneaky bug has been fixed. Please, update your local repository and check if it works for you too.

Sorry for not being able to work on this before.

Great, thanks @imdario !
