After ClickHouse#11599 it is possible that messages of the
ReadBufferFromKafkaConsumer will be cleaned-up right in
read_kafka_message callback (from KafkaBlockInputStream) if the stop
flag isset (i.e. DROP TABLE is waiting the consumer), and if
read_kafka_message already processed some rows it will not return 0 and
the loop after will try to get current topic from the buffer, which uses
messages in the underlying and this will got SIGSEGV:

Possible approach for fixing #10574

The problem is that prepared sets are built correctly, it is a hash map of key -> set
where key is a hash of AST and list of data types (when we a list of
tuples of literals).

However, when the key is built from the index to try and find if there
exists a prepared set that would match it looks for data types of the
primary key (see how data_types is populated) because the primary key
has only one field (v in my example) it can not find the prepared set.

The patch looks for any prepared indexes where data types match for the
subset of fields found in primary key, we are not interested in other
fields anyway for the purpose of primary key pruning.

By default IMPORTED target has a scope in the directory in which it is created

Target "clickhouse" links to target "Poco::Data::ODBC" but the target was not

target_compile_definitions may only set INTERFACE properties on IMPORTED targets

* Fix version column in replicated version collapsing merge tree (#12121)

* poco-cmake: Fix Poco::Data::ODBC target when UNBUNDLED

By default IMPORTED target has a scope in the directory in which it is created
and below. This leads to the following issues when building UNBUNDLED:

Target "clickhouse" links to target "Poco::Data::ODBC" but the target was not
found.  Perhaps a find_package() call is missing for an IMPORTED target, or an
ALIAS target is missing?

* Add missed <atomic> include in ProxyListConfiguration

* Rename test

* Update arraySum.cpp

* Run perf tests with memory sampling (for allocations >1M)

This is to know the memory allocation size distribution, that can be
obtained later from left-metric-log.tsv.

This is an attempt to tune tcmalloc (new CPP version by google) to use
lock-free part of the allocator for typical allocations (and it is a bad
idea just to increase kMaxSize there, since number of allocation for
each size class is also important).

P.S. hope that this file will be applied, if no, then the same effect
can be reached by tunning defaults in Settings.h

* [docs] refactor Domains overview (#12186)

* Add to images.json

* Sanitize LINK_LIBRARIES property for the directories (#12160)

When you will try to link target with the directory (that exists), cmake will
skip this without an error, only the following warning will be reported:

    target_link_libraries(main /tmp)

    WARNING: Target "main" requests linking to directory "/tmp".  Targets may link only to libraries.  CMake is dropping the item.

And there is no cmake policy that controls this.
(I guess the reason that it is allowed is because of FRAMEWORK for OSX).

So to avoid error-prone cmake rules, this can be sanitized.
There are the following ways:
- overwrite target_link_libraries()/link_libraries() and check *before*
  calling real macro, but this requires duplicate all supported syntax
  -- too complex
- overwrite target_link_libraries() and check LINK_LIBRARIES property, this
  works great
  -- but cannot be used with link_libraries()
- use BUILDSYSTEM_TARGETS property to get list of all targets and sanitize
  -- this will work.

I also tested it with the following patch:

    $ git di
    diff --git a/base/daemon/CMakeLists.txt b/base/daemon/CMakeLists.txt
    index 26d59a5..35e6ff6432 100644
    --- a/base/daemon/CMakeLists.txt

     if (USE_SENTRY)
         target_link_libraries (daemon PRIVATE ${SENTRY_LIBRARY})
    +    target_link_libraries (daemon PRIVATE /tmp)
     endif ()

And it works:

    CMake Error at cmake/sanitize_target_link_libraries.cmake:48 (message):

* [docs] refactor Domains overview (#12186)

* Sanitize LINK_LIBRARIES property for the directories (#12160)

When you will try to link target with the directory (that exists), cmake will
skip this without an error, only the following warning will be reported:

    target_link_libraries(main /tmp)

    WARNING: Target "main" requests linking to directory "/tmp".  Targets may link only to libraries.  CMake is dropping the item.

And there is no cmake policy that controls this.
(I guess the reason that it is allowed is because of FRAMEWORK for OSX).

So to avoid error-prone cmake rules, this can be sanitized.
There are the following ways:
- overwrite target_link_libraries()/link_libraries() and check *before*
  calling real macro, but this requires duplicate all supported syntax
  -- too complex
- overwrite target_link_libraries() and check LINK_LIBRARIES property, this
  works great
  -- but cannot be used with link_libraries()
- use BUILDSYSTEM_TARGETS property to get list of all targets and sanitize
  -- this will work.

I also tested it with the following patch:

    $ git di
    diff --git a/base/daemon/CMakeLists.txt b/base/daemon/CMakeLists.txt
    index 26d59a5..35e6ff6432 100644
    --- a/base/daemon/CMakeLists.txt

     if (USE_SENTRY)
         target_link_libraries (daemon PRIVATE ${SENTRY_LIBRARY})
    +    target_link_libraries (daemon PRIVATE /tmp)
     endif ()

And it works:

* kafka: fix SIGSEGV on DROP TABLE

After #11599 it is possible that messages of the
ReadBufferFromKafkaConsumer will be cleaned-up right in
read_kafka_message callback (from KafkaBlockInputStream) if the stop
flag isset (i.e. DROP TABLE is waiting the consumer), and if
read_kafka_message already processed some rows it will not return 0 and
the loop after will try to get current topic from the buffer, which uses
messages in the underlying and this will got SIGSEGV:

* poco-cmake: Fix Poco::Data::ODBC target when UNBUNDLED

By default IMPORTED target has a scope in the directory in which it is created
and below. This leads to the following issues when building UNBUNDLED:

Target "clickhouse" links to target "Poco::Data::ODBC" but the target was not
found.  Perhaps a find_package() call is missing for an IMPORTED target, or an
ALIAS target is missing?

This is to know the memory allocation size distribution, that can be
obtained later from left-metric-log.tsv.

This is an attempt to tune tcmalloc (new CPP version by google) to use
lock-free part of the allocator for typical allocations (and it is a bad
idea just to increase kMaxSize there, since number of allocation for
each size class is also important).

P.S. hope that this file will be applied, if no, then the same effect
can be reached by tunning defaults in Settings.h

* [docs] refactor Domains overview (#12186)

* Add to images.json

* Sanitize LINK_LIBRARIES property for the directories (#12160)

When you will try to link target with the directory (that exists), cmake will
skip this without an error, only the following warning will be reported:

    target_link_libraries(main /tmp)

    WARNING: Target "main" requests linking to directory "/tmp".  Targets may link only to libraries.  CMake is dropping the item.

And there is no cmake policy that controls this.
(I guess the reason that it is allowed is because of FRAMEWORK for OSX).

So to avoid error-prone cmake rules, this can be sanitized.
There are the following ways:
- overwrite target_link_libraries()/link_libraries() and check *before*
  calling real macro, but this requires duplicate all supported syntax
  -- too complex
- overwrite target_link_libraries() and check LINK_LIBRARIES property, this
  works great
  -- but cannot be used with link_libraries()
- use BUILDSYSTEM_TARGETS property to get list of all targets and sanitize
  -- this will work.

I also tested it with the following patch:

    $ git di
    diff --git a/base/daemon/CMakeLists.txt b/base/daemon/CMakeLists.txt
    index 26d59a5..35e6ff6432 100644
    --- a/base/daemon/CMakeLists.txt
    +++ b/base/daemon/CMakeLists.txt
    @@ -9,4 +9,5 @@ target_link_libraries (daemon PUBLIC loggers PRIVATE clickhouse_common_io clickh

     if (USE_SENTRY)
         target_link_libraries (daemon PRIVATE ${SENTRY_LIBRARY})
    +    target_link_libraries (daemon PRIVATE /tmp)
     endif ()

And it works:

    CMake Error at cmake/sanitize_target_link_libraries.cmake:48 (message):

* kafka: fix SIGSEGV on DROP TABLE

After #11599 it is possible that messages of the
ReadBufferFromKafkaConsumer will be cleaned-up right in
read_kafka_message callback (from KafkaBlockInputStream) if the stop
flag isset (i.e. DROP TABLE is waiting the consumer), and if
read_kafka_message already processed some rows it will not return 0 and
the loop after will try to get current topic from the buffer, which uses
messages in the underlying and this will got SIGSEGV:

By default IMPORTED target has a scope in the directory in which it is created
and below. This leads to the following issues when building UNBUNDLED:

Target "clickhouse" links to target "Poco::Data::ODBC" but the target was not
found.  Perhaps a find_package() call is missing for an IMPORTED target, or an
ALIAS target is missing?

This is to know the memory allocation size distribution, that can be
obtained later from left-metric-log.tsv.

This is an attempt to tune tcmalloc (new CPP version by google) to use
lock-free part of the allocator for typical allocations (and it is a bad
idea just to increase kMaxSize there, since number of allocation for
each size class is also important).

P.S. hope that this file will be applied, if no, then the same effect
can be reached by tunning defaults in Settings.h
