WebObjects 4.5: Memory Leak in LDAPAdaptor Example Code

Symptom

There is a memory leak in the LDAPAdaptor example source code located in $NEXT_ROOT/Developer/Examples/EnterpriseObjects/Sources/LDAPAdaptor

Solution

A memory leak exists in LDAPChannel.m line 417. The following method declares an NSMutableArray, but never autoreleases it:

- (NSArray *) ldapAttributes

The original line looks like this:

ldapAtts = [[NSMutableArray alloc] initWithCapacity:count];

To correct the leak, change line 417 to read:

ldapAtts = [[[NSMutableArray alloc] initWithCapacity:count] autorelease];

After making this source code change, be sure to recompile the adaptor to incorporate the modifications.
