Missing <chrono> for gtest_sensitive_data_masker 
I guess that <chrono> had been included somewhere before in primary env.

Merge pull request #6873 from yandex/aku/internal-iteration 
Use internal iteration over hash tables in Aggregator.
 2019-09-10 22:02:53 +03:00
Amos Bird
8f28a36c17 Use internal iteration over hash tables in Aggregator. 
For compound hash tables such as the future StringHashMap, an
iterator-based API might be inefficient for iterating over a table or
for merging two tables, because:

1) the key has to be converted to a general format from a from a
   component-specific format, which may differ between the components;

2) the information about the component of the compound hash table to
   which the value belongs is lost, and has to be recalculated if the
   value is reinserted.

A more efficient approach is to use internal iteration, that is,
map-like functions, which avoids unnecessary conversions when iterating,
and allows to use an efficient component-wise approach when merging.

160e0faf77 Do not use iterator::getValue() in Aggregator. 
Use separate key and "mapped" value references instead. This is
important for hash tables that do not store the key/"mapped" pair
directly, and cannot provide this interface without some runtime
overhead.

Alexander Kuzmenkov
8e9a8584e0 Do not provide mutable key access in hash map cells. 
We don't need it anymore after we changed the hash table key memory
management to use callbacks. Removing this interface is important for
hash maps that do not store the key, such as FixedHashMap or the
prospective compound StringHashMap.

4f71fe715c Strong exception safety guarantee: 
Based on std::list<>::emplace_back() and std::unordered_map<>::emplace()
provide strong exception safety, RWLockImpl is now changed to provide
the same level of exception safety.
