Zach Howe updated THRIFT-3750:
------------------------------
Priority: Major (was: Critical)
> NSCopying copyWithZone: implementation does not check isSet
> -----------------------------------------------------------
>
> Key: THRIFT-3750
> URL: https://issues.apache.org/jira/browse/THRIFT-3750
> Project: Thrift
> Issue Type: Bug
> Components: Cocoa - Compiler
> Affects Versions: 1.0
> Reporter: Zach Howe
> Fix For: 1.0
>
>
> The NSCopying copyWithZone: implementation does not check isSet. This causes
> the copy not to be a true copy, since all the isSet properties will be set to
> YES on the newly copied object.
> Note, updating to provide some more clarity:
> In this example, it's fixed:
> {code}
> - (instancetype) copyWithZone:(NSZone *)zone
> {
> Foo * val = [Foo new];
> if (_nameIsSet)
> {
> val.name = [self.name copy];
> }
> return val;
> }
> {code}
> Without the if check on _nameIsSet, the newly copied object will have
> _nameIsSet set to YES but with a nil name.
> {code}
> - (void) setName: (NSString *) name {
> _name = name;
> _nameIsSet = YES;
> }
> {code}
