@OlegGalizin ping, Client/ClientCase.QueryParameters is failing on almost every platform... BTW, to simplify build-test-review loop, you can fix test using your own fork of clickhouse-ccp. Runners are provided by github, so it would work on your repo.

Client/ClientCase.QueryParameters is failing on almost every platform

@Enmk I see. Clickhouse server doesn't support parameters in the test system.

+-----------+
| version() |
+-----------+
|    String |
+-----------+
| 22.3.20.29 |
+-----------+

I checked ClickHouse 24.7.1.2195 (revision: 54488, git hash: 452d463d77eed30aab18c77933e68316f8c57295 To work with parameters revision of ClickHouse server must be >= 54459

Do you want to switch off the test? Will you update the test environment?

Some unit tests are conditionally skipped based on clickhouse version, please check the code and modify your tests accordingly.

And please either get rid of find_quoted_chars or provide a benchmark that shows at least 10% smaller time against std::find_first_of. (e.g. using https://quick-bench.com)
