c1dea66907 Move TraceCollector into Interpreters

aee034a597 Use explicit template instantiation for SystemLog 
- Move some code into module part to avoid dependency from IStorage in SystemLog
- Remove extra headers from SystemLog.h
- Rewrite some code that was relying on headers that was included by SystemLog.h

v2: rebase
v3: squash move into module part with explicit template instantiation
    (to make each commit self compilable after rebase)

1637c41d42 Remove leftovers of old _shard_num via identifier implementation 2022-01-10 21:21:24 +03:00
Azat Khuzhin
97acf190ed Replace old _shard_num implementation with shardNum() function 
_shard_num via constant identifier (from #7624) has too much issues,
take a look at #16947 for example.

shardNum() function (from #27020) should works better.

This changes the behaviour of _shard_num slightly, now it returns nested
shard number in case of nested distributed tables (Distributed over
Distributed), but this should be minor.

v2: Rewrite _shard_num to shardNum() in TreeRewriter

There was a fix in #32572, but it was not complete (yes it reduced the
race window a lot, but not completely), since the inner table still can
go away after the INSERT chain was built, to fix this obtain the
reference earlier.

Follow-up for: #32572 (cc @tavplubix)

6fbb9f5e87 Implement EXPLAIN TABLE OVERRIDE for pre-validating overrides. 
Example:

```sql
EXPLAIN TABLE OVERRIDE mysql('127.0.0.1:3306', 'db', 'table', 'user', 'pw')
    PARTITION BY tuple(toYYYYMM(created), id % 8)
```

Validations done:

 * check that storage overrides do not reference unknown or nullable columns
 * check that default specifier is not modified for columns

Start/stop servers when listen_host/*_port changes 
This allows starting and stopping separately each protocol server
without restarting ClickHouse.

This also allows adding or removing `listen_host` entries, which
start and stops servers for all enabled ports.

When stopping a server, the listening socket is immediately closed
(and available for another server).

Protocols with persistent connections try to wait for any currently
running query to finish before closing the connection, but idle
connection are closed quickly (depending on how often the protocol
is polled).

An extra ProfileEvent is added, `MainConfigLoads`, it is
incremented every time the configuration is reloaded. This helps
when trying to assess whether the new configuration was applied.

5fafeea763 Recreate system.*_log tables in case of different engine/partition_by. 
- Mark getCreateTableQuery() non virtual to call it from ctor
- Make check for CREATE TABLE simpler (by caching result)
- Extend error message.

v2: at SystemLog tables has not been initialized yet, so SHOW CREATE
cannot be obtained for the existing table, move the check to the
prepareTable() call.
v3: reset UUID and SETTINGS of MergeTree in CREATE TABLE query
v4: fix re-creating table with the same UUID
