0046b9f137 Wait for jobs to finish on exception (fixes rare segfaults) (#7350) 2019-10-17 17:41:27 +03:00
Alexander Kuzmenkov
f3bde19b74 Do not use iterators in find() and emplace() methods of hash tables.
Instead, these methods return a pointer to the required data as they are
stored inside the hash table. The caller uses overloaded functions to
get the key and "mapped" values from this pointer. Such an interface
avoids the need for constructing iterator-like wrapper objects, which is
especially important for compound hash tables such as the future
StringHashMap.

26ab5dd7a7 A Proper lookup table that uses HashTable's API
This is the first step of allowing heterogeneous cells in hash tables.

performance test results are

```

1. HashMap<UInt16, UInt8, TrivialHash, HashTableFixedGrower<16>>;
2. NewLookupMap<UInt16, UInt8>
