+// Description:
+// Summary:
+// A regression test to check changes to the CContactDatabase::SortL() API
+// that provide backward compatibility with <=v9.2 for some 3rd party apps 
+// that misuse the API.
+// Full description:
+// In cntmodel <=v9.2, sorting on the database was done with the now deprecated
+// method:
+// CContactDatabase::SortL(CArrayFix<TSortPref>* aSortOrder)
+// As is implied by the pass-by-pointer semantics, this has always taken
+// ownership of aSortOrder. In the past, aSortOrder was held as a data member
+// of CContactDatabase and so was held for the lifetime of the database object.
+// Some 3rd party apps called SortL(), mistakenly thinking that ownership
+// of aSortOrder had not been passed. Consequently, they used aSortOrder after 
+// the call. They were able to get away with this because aSortOrder had not 
+// been deleted yet at that point.
+// In cntmodel >=v9.3, the way sort preferences are stored changed and so
+// aSortOrder was deleted at the end of SortL() as it was no longer needed. 
+// The impact of this change was that aSortOrder was no longer available for
+// use after a call to SortL() and so the 3rd party apps panicked.
+// The fix for INC119319 provides a work-around that re-introduces the 
+// CContactDatabase member variable to hold aSortOrder for the lifetime of the
+// database object, as in pre-v9.3 versions. This extended lifetime allows the
+// 3rd party apps to continue to use aSortOrder as they had done before. 
+// Actions:
+// -- Create a new database;
+// -- Create and insert 2 contact items into the database;
+// -- Call SortL() to sort the contact items;
+// -- Test whether aSortOrder can still be used, failing if not;
+// -- Clean up the database.
+// Associated defect:
+// INC119319 Break in CContactDatabase::SortL
+// [Not actually a defect but a work-around was provided for compatibility.]

+// James Clarke
