* Rename and improve regression methods. [#5492](https://github.com/yandex/ClickHouse/pull/5492) ([Quid37](https://github.com/Quid37))
* Clearer interfaces of string searchers. [#5586](https://github.com/yandex/ClickHouse/pull/5586) ([Danila Kutenin](https://github.com/danlark1))
### Bug Fix
* Fix potential data loss in Kafka [#5445](https://github.com/yandex/ClickHouse/pull/5445) ([Ivan](https://github.com/abyss7))
* Fix potential infinite loop in `PrettySpace` format when called with zero columns [#5560](https://github.com/yandex/ClickHouse/pull/5560) ([Olga Khvostikova](https://github.com/stavrolia))
* Fixed UInt32 overflow bug in linear models. Allow eval ML model for non-const model argument. [#5516](https://github.com/yandex/ClickHouse/pull/5516) ([Nikolai Kochetov](https://github.com/KochetovNicolai))
* `ALTER TABLE ... DROP INDEX IF EXISTS ...` should not raise an exception if provided index does not exist [#5524](https://github.com/yandex/ClickHouse/pull/5524) ([Gleb Novikov](https://github.com/NanoBjorn))
* Fix segfault with `bitmapHasAny` in scalar subquery [#5528](https://github.com/yandex/ClickHouse/pull/5528) ([Zhichang Yu](https://github.com/yuzhichang))

[#5588](https://github.com/yandex/ClickHouse/pull/5588) ([Danila Kutenin](https://github.com/danlark1))
* Fix the issue when settings for ExternalData requests couldn't use ClickHouse settings. Also, for now, settings `date_time_input_format` and `low_cardinality_allow_in_native_format` cannot be used because of the ambiguity of names (in external data it can be interpreted as table format and in the query it can be a setting). [#5455](https://github.com/yandex/ClickHouse/pull/5455) ([Danila Kutenin](https://github.com/danlark1))

* Throw an exception on wrong integers in `dictGetT` functions instead of crash. [#5446](https://github.com/yandex/ClickHouse/pull/5446) ([Artem Zuikov](https://github.com/4ertus2))
* Fix wrong element_count and load_factor for hashed dictionary in `system.dictionaries` table. [#5440](https://github.com/yandex/ClickHouse/pull/5440) ([Azat Khuzhin](https://github.com/azat))
### Build/Testing/Packaging Improvement

* Add a function basename, with a similar behaviour to a basename function, which exists in a lot of languages (`os.path.basename` in python, `basename` in PHP, etc...). Work with both an UNIX-like path or a Windows path. [#5136](https://github.com/yandex/ClickHouse/pull/5136) ([Guillaume Tassery](https://github.com/YiuRULE))
* Added `LIMIT n, m BY` or `LIMIT m OFFSET n BY` syntax to set offset of n for LIMIT BY clause. [#5138](https://github.com/yandex/ClickHouse/pull/5138) ([Anton Popov](https://github.com/CurtizJ))
* Added new data type `SimpleAggregateFunction`, which allows to have columns with light aggregation in an `AggregatingMergeTree`. This can only be used with simple functions like `any`, `anyLast`, `sum`, `min`, `max`. [#4629](https://github.com/yandex/ClickHouse/pull/4629) ([Boris Granveaud](https://github.com/bgranvea))
* Added support for non-constant arguments in function `ngramDistance` [#5198](https://github.com/yandex/ClickHouse/pull/5198) ([Danila Kutenin](https://github.com/danlark1))
* Added functions `skewPop`, `skewSamp`, `kurtPop` and `kurtSamp` to compute for sequence skewness, sample skewness, kurtosis and sample kurtosis respectively. [#5200](https://github.com/yandex/ClickHouse/pull/5200) ([hcz](https://github.com/hczhcz))
* Support rename operation for `MaterializeView` storage. [#5209](https://github.com/yandex/ClickHouse/pull/5209) ([Guillaume Tassery](https://github.com/YiuRULE))

* Add `toDecimal*OrZero` and `toDecimal*OrNull` functions. [#5291](https://github.com/yandex/ClickHouse/pull/5291) ([Artem Zuikov](https://github.com/4ertus2))
* Support Decimal types in functions: `quantile`, `quantiles`, `median`, `quantileExactWeighted`, `quantilesExactWeighted`, medianExactWeighted. [#5304](https://github.com/yandex/ClickHouse/pull/5304) ([Artem Zuikov](https://github.com/4ertus2))
* Added `toValidUTF8` function, which replaces all invalid UTF-8 characters by replacement character <20> (U+FFFD). [#5322](https://github.com/yandex/ClickHouse/pull/5322) ([Danila Kutenin](https://github.com/danlark1))
* Added `format` function. Formatting constant pattern (simplified Python format pattern) with the strings listed in the arguments. [#5330](https://github.com/yandex/ClickHouse/pull/5330) ([Danila Kutenin](https://github.com/danlark1))
* Added `system.detached_parts` table containing information about detached parts of `MergeTree` tables. [#5353](https://github.com/yandex/ClickHouse/pull/5353) ([akuzm](https://github.com/akuzm))
* Added `ngramSearch` function to calculate the non-symmetric difference between needle and haystack. [#5418](https://github.com/yandex/ClickHouse/pull/5418)[#5422](https://github.com/yandex/ClickHouse/pull/5422) ([Danila Kutenin](https://github.com/danlark1))
* Implementation of basic machine learning methods (stochastic linear regression and logistic regression) using aggregate functions interface. Has different strategies for updating model weights (simple gradient descent, momentum method, Nesterov method). Also supports mini-batches of custom size. [#4943](https://github.com/yandex/ClickHouse/pull/4943) ([Quid37](https://github.com/Quid37))
* Implementation of `geohashEncode` and `geohashDecode` functions. [#5003](https://github.com/yandex/ClickHouse/pull/5003) ([Vasily Nemkov](https://github.com/Enmk))
* Added aggregate function `timeSeriesGroupSum`, which can aggregate different time series that sample timestamp not alignment. It will use linear interpolation between two sample timestamp and then sum time-series together. Added aggregate function `timeSeriesGroupRateSum`, which calculates the rate of time-series and then sum rates together. [#4542](https://github.com/yandex/ClickHouse/pull/4542) ([Yangkuan Liu](https://github.com/LiuYangkuan))
* Added functions `IPv4CIDRtoIPv4Range` and `IPv6CIDRtoIPv6Range` to calculate the lower and higher bounds for an IP in the subnet using a CIDR. [#5095](https://github.com/yandex/ClickHouse/pull/5095) ([Guillaume Tassery](https://github.com/YiuRULE))
* Add a X-ClickHouse-Summary header when we send a query using HTTP with enabled setting `send_progress_in_http_headers`. Return the usual information of X-ClickHouse-Progress, with additional information like how many rows and bytes were inserted in the query. [#5116](https://github.com/yandex/ClickHouse/pull/5116) ([Guillaume Tassery](https://github.com/YiuRULE))
### Improvements
* Added `max_parts_in_total` setting for MergeTree family of tables (default: 100 000) that prevents unsafe specification of partition key #5166. [#5171](https://github.com/yandex/ClickHouse/pull/5171) ([alexey-milovidov](https://github.com/alexey-milovidov))
* `clickhouse-obfuscator`: derive seed for individual columns by combining initial seed with column name, not column position. This is intended to transform datasets with multiple related tables, so that tables will remain JOINable after transformation. [#5178](https://github.com/yandex/ClickHouse/pull/5178) ([alexey-milovidov](https://github.com/alexey-milovidov))
* Added functions `JSONExtractRaw`, `JSONExtractKeyAndValues`. Renamed functions `jsonExtract<type>` to `JSONExtract<type>`. When something goes wrong these functions return the correspondent values, not `NULL`. Modified function `JSONExtract`, now it gets the return type from its last parameter and doesn't inject nullables. Implemented fallback to RapidJSON in case AVX2 instructions are not available. Simdjson library updated to a new version. [#5235](https://github.com/yandex/ClickHouse/pull/5235) ([Vitaly Baranov](https://github.com/vitlibar))
* Now `if` and `multiIf` functions don't rely on the condition's `Nullable`, but rely on the branches for sql compatibility. [#5238](https://github.com/yandex/ClickHouse/pull/5238) ([Jian Wu](https://github.com/janplus))
* `In` predicate now generates `Null` result from `Null` input like the `Equal` function. [#5152](https://github.com/yandex/ClickHouse/pull/5152) ([Jian Wu](https://github.com/janplus))
* Check the time limit every (flush_interval / poll_timeout) number of rows from Kafka. This allows to break the reading from Kafka consumer more frequently and to check the time limits for the top-level streams [#5249](https://github.com/yandex/ClickHouse/pull/5249) ([Ivan](https://github.com/abyss7))
* Link rdkafka with bundled SASL. It should allow to use SASL SCRAM authentication [#5253](https://github.com/yandex/ClickHouse/pull/5253) ([Ivan](https://github.com/abyss7))
* Batched version of RowRefList for ALL JOINS. [#5267](https://github.com/yandex/ClickHouse/pull/5267) ([Artem Zuikov](https://github.com/4ertus2))
* clickhouse-server: more informative listen error messages. [#5268](https://github.com/yandex/ClickHouse/pull/5268) ([proller](https://github.com/proller))
* Support dictionaries in clickhouse-copier for functions in `<sharding_key>` [#5270](https://github.com/yandex/ClickHouse/pull/5270) ([proller](https://github.com/proller))
* Add new setting `kafka_commit_every_batch` to regulate Kafka committing policy.
It allows to set commit mode: after every batch of messages is handled, or after the whole block is written to the storage. It's a trade-off between losing some messages or reading them twice in some extreme situations. [#5308](https://github.com/yandex/ClickHouse/pull/5308) ([Ivan](https://github.com/abyss7))
* Make `windowFunnel` support other Unsigned Integer Types. [#5320](https://github.com/yandex/ClickHouse/pull/5320) ([sundyli](https://github.com/sundy-li))
* Allow to shadow virtual column `_table` in Merge engine. [#5325](https://github.com/yandex/ClickHouse/pull/5325) ([Ivan](https://github.com/abyss7))
* Make `sequenceMatch` aggregate functions support other unsigned Integer types [#5339](https://github.com/yandex/ClickHouse/pull/5339) ([sundyli](https://github.com/sundy-li))
* Better error messages if checksum mismatch is most likely caused by hardware failures. [#5355](https://github.com/yandex/ClickHouse/pull/5355) ([alexey-milovidov](https://github.com/alexey-milovidov))
* Check that underlying tables support sampling for `StorageMerge` [#5366](https://github.com/yandex/ClickHouse/pull/5366) ([Ivan](https://github.com/abyss7))
* Сlose MySQL connections after their usage in external dictionaries. It is related to issue #893. [#5395](https://github.com/yandex/ClickHouse/pull/5395) ([Clément Rodriguez](https://github.com/clemrodriguez))
* Improvements of MySQL Wire Protocol. Changed name of format to MySQLWire. Using RAII for calling RSA_free. Disabling SSL if context cannot be created. [#5419](https://github.com/yandex/ClickHouse/pull/5419) ([Yuriy Baranov](https://github.com/yurriy))
* clickhouse-client: allow to run with unaccessable history file (read-only, no disk space, file is directory, ...). [#5431](https://github.com/yandex/ClickHouse/pull/5431) ([proller](https://github.com/proller))
* Respect query settings in asynchronous INSERTs into Distributed tables. [#4936](https://github.com/yandex/ClickHouse/pull/4936) ([TCeason](https://github.com/TCeason))
* Renamed functions `leastSqr` to `simpleLinearRegression`, `LinearRegression` to `linearRegression`, `LogisticRegression` to `logisticRegression`. [#5391](https://github.com/yandex/ClickHouse/pull/5391) ([Nikolai Kochetov](https://github.com/KochetovNicolai))
### Performance Improvements
* Paralellize processing of parts in alter modify query. [#4639](https://github.com/yandex/ClickHouse/pull/4639) ([Ivan Kush](https://github.com/IvanKush))
* Optimizations in regular expressions extraction. [#5193](https://github.com/yandex/ClickHouse/pull/5193) [#5191](https://github.com/yandex/ClickHouse/pull/5191) ([Danila Kutenin](https://github.com/danlark1))
* Do not add right join key column to join result if it's used only in join on section. [#5260](https://github.com/yandex/ClickHouse/pull/5260) ([Artem Zuikov](https://github.com/4ertus2))
* Freeze the Kafka buffer after first empty response. It avoids multiple invokations of `ReadBuffer::next()` for empty result in some row-parsing streams. [#5283](https://github.com/yandex/ClickHouse/pull/5283) ([Ivan](https://github.com/abyss7))
* `concat` function optimization for multiple arguments. [#5357](https://github.com/yandex/ClickHouse/pull/5357) ([Danila Kutenin](https://github.com/danlark1))
* Query optimisation. Allow push down IN statement while rewriting commа/cross join into inner one. [#5396](https://github.com/yandex/ClickHouse/pull/5396) ([Artem Zuikov](https://github.com/4ertus2))
* Upgrade our LZ4 implementation with reference one to have faster decompression. [#5070](https://github.com/yandex/ClickHouse/pull/5070) ([Danila Kutenin](https://github.com/danlark1))

* Добавлена проверка ограничения по времени выполенения запроса через каждые (flush_interval / poll_timeout) строк при чтении из движка Kafka. Это позволяет чаще прерывать чтение из движка Kafka и чаще проверять ограничение по времени на более высоком уровне конвеера выполнения запроса. [#5249](https://github.com/yandex/ClickHouse/pull/5249) ([Ivan](https://github.com/abyss7))
* Теперь библиотека rdkafka линкуется c bundled библиотекой SASL. Это позволяет использовать SASL SCRAM аутентификацию. [#5253](https://github.com/yandex/ClickHouse/pull/5253) ([Ivan](https://github.com/abyss7))
* clickhouse-server: более информативные сообщения об ошибках прослушивания. [#5268](https://github.com/yandex/ClickHouse/pull/5268) ([proller](https://github.com/proller))

* Добавлена настройка `kafka_commit_every_batch` для регулирования чтения данных из движка Kafka. Позволяет установить вид чтения: после каждого полученного пакета сообщений или после того как блок записан в таблицу. [#5308](https://github.com/yandex/ClickHouse/pull/5308) ([Ivan](https://github.com/abyss7))
* Добавлена поддержка беззнаковых целых типов отличных от UInt32 в функциях `windowFunnel`, `sequenceMatch`. [#5339](https://github.com/yandex/ClickHouse/pull/5339) [#5320](https://github.com/yandex/ClickHouse/pull/5320) ([sundyli](https://github.com/sundy-li))
* В движке Merge виртуальный столбец с названием `_table` (содержащий название таблицы) теперь недоступен, если он присутствует в таблицах-источниках. [#5325](https://github.com/yandex/ClickHouse/pull/5325) ([Ivan](https://github.com/abyss7))
* Более понятные сообщения об ошибках, если чексуммы не совпадают вероятнее всего из-за ошибок на аппаратном уровне. [#5355](https://github.com/yandex/ClickHouse/pull/5355) ([alexey-milovidov](https://github.com/alexey-milovidov))
* Для движка `Merge` добавлена проверка на то, что таблицы-источники поддерживают семплирование. [#5366](https://github.com/yandex/ClickHouse/pull/5366) ([Ivan](https://github.com/abyss7))
* Теперь после использования MySQL в качестве внешнего словаря закрывается соединение. [#5395](https://github.com/yandex/ClickHouse/pull/5395) ([Clément Rodriguez](https://github.com/clemrodriguez))
* Улучшения в протоколе MySQL Wire. Формат переименован из `MySQL` to `MySQLWire`. Теперь SSL недоступно, если не удалось создать SSL контекст. [#5419](https://github.com/yandex/ClickHouse/pull/5419) ([Yuriy Baranov](https://github.com/yurriy))
* clickhouse-client: теперь можно запустить клиент, если файл истории недоступен. [#5431](https://github.com/yandex/ClickHouse/pull/5431) ([proller](https://github.com/proller))
* Теперь учитываются настройки запроса при асинхронных вставках в таблицу типа Distributed. [#4936](https://github.com/yandex/ClickHouse/pull/4936) ([TCeason](https://github.com/TCeason))
* Переименованы функции `leastSqr` в `simpleLinearRegression`, `LinearRegression` в `linearRegression`, `LogisticRegression` в `logisticRegression`. [#5391](https://github.com/yandex/ClickHouse/pull/5391) ([Nikolai Kochetov](https://github.com/KochetovNicolai))

* Убрана возможность преобразований из float Inf/NaN в Decimal (теперь бросается исключение). [#5282](https://github.com/yandex/ClickHouse/pull/5282) ([Artem Zuikov](https://github.com/4ertus2))
* Исправлен data race в запросе `RENAME`. [#5247](https://github.com/yandex/ClickHouse/pull/5247) ([Winter Zhang](https://github.com/zhang2014))
* Отключен LFAlloc. Использование LFAlloc могло приводить к ошибкам MAP_FAILED при использовании UncompressedCache и в результате к падению запросов на высоконагруженных серверах. [cfdba93](https://github.com/yandex/ClickHouse/commit/cfdba938ce22f16efeec504f7f90206a515b1280)([Danila Kutenin](https://github.com/danlark1))
## ClickHouse release 19.6.2.11, 2019-05-13
### Новые возможности
@ -1826,7 +1936,7 @@ Kutenin](https://github.com/danlark1))
- cleanup_delay_period - периодичность запуска очистки неактуальных данных
- replicated_can_become_leader - запретить реплике становиться лидером (и назначать мержи)
* Ускорена очистка неактуальных данных из ZooKeeper
* Множественные улучшения и исправления работы кластерных DDL запросов. В частности, добавлена настройка distributed_ddl_task_timeout, ограничивающая время ожидания ответов серверов кластера.
* Множественные улучшения и исправления работы кластерных DDL запросов. В частности, добавлена настройка distributed_ddl_task_timeout, ограничивающая время ожидания ответов серверов кластера. Если запрос не успел выполниться на всех нодах в установленное время, ответ будет содержать timeout ошибку и дальнейшее выполнение этого запроса будет происходить в асинхронном режиме
* Улучшено отображение стэктрейсов в логах сервера
* Добавлен метод сжатия none
* Возможность использования нескольких секций dictionaries_config в config.xml

Style guide for the util folder is a stricter version of general style guide (mostly in terms of ambiguity resolution).
* all {} must be in K&R style
* &, * tied closer to a type, not to variable
* always use `using` not `typedef`
* even a single line block must be in braces {}:
```
if (A) {
B();
}
```
* _ at the end of private data member of a class - `First_`, `Second_`
* every .h file must be accompanied with corresponding .cpp to avoid a leakage and check that it is self contained
* prohibited to use `printf`-like functions
Things declared in the general style guide, which sometimes are missed:
* `template <`, not `template<`
* `noexcept`, not `throw ()` nor `throw()`, not required for destructors
* indents inside `namespace` same as inside `class`
Requirements for a new code (and for corrections in an old code which involves change of behaviour) in util:
* presence of UNIT-tests
* presence of comments in Doxygen style
* accessors without Get prefix (`Length()`, but not `GetLength()`)
This guide is not a mandatory as there is the general style guide.
Nevertheless if it is not followed, then a next `ya style .` run in the util folder will undeservedly update authors of some lines of code.
Thus before a commit it is recommended to run `ya style .` in the util folder.

#include "dwarf.h"
/* This header file defines the format of a DWARF exception-header
section (.eh_frame_hdr, pointed to by program-header
PT_GNU_EH_FRAME). The exception-header is self-describing in the
sense that the format of the addresses contained in it is expressed
as a one-byte type-descriptor called a "pointer-encoding" (PE).
The exception header encodes the address of the .eh_frame section
and optionally contains a binary search table for the
Frame Descriptor Entries (FDEs) in the .eh_frame. The contents of
.eh_frame has the format described by the DWARF v3 standard
(http://www.eagercon.com/dwarf/dwarf3std.htm), except that code
addresses may be encoded in different ways. Also, .eh_frame has
augmentations that allow encoding a language-specific data-area
(LSDA) pointer and a pointer to a personality-routine.
Details:
The Common Information Entry (CIE) associated with an FDE may
contain an augmentation string. Each character in this string has
a specific meaning and either one or two associated operands. The
operands are stored in an augmentation body which appears right
after the "return_address_register" member and before the
"initial_instructions" member. The operands appear in the order
in which the characters appear in the string. For example, if the
augmentation string is "zL", the operand for 'z' would be first in
the augmentation body and the operand for 'L' would be second.
The following characters are supported for the CIE augmentation
string:
'z': The operand for this character is a uleb128 value that gives the
length of the CIE augmentation body, not counting the length
of the uleb128 operand itself. If present, this code must
appear as the first character in the augmentation body.
'L': Indicates that the FDE's augmentation body contains an LSDA
pointer. The operand for this character is a single byte
that specifies the pointer-encoding (PE) that is used for
the LSDA pointer.
'R': Indicates that the code-pointers (FDE members
"initial_location" and "address_range" and the operand for
DW_CFA_set_loc) in the FDE have a non-default encoding. The
operand for this character is a single byte that specifies
the pointer-encoding (PE) that is used for the
code-pointers. Note: the "address_range" member is always
encoded as an absolute value. Apart from that, the specified
FDE pointer-encoding applies.
'P': Indicates the presence of a personality routine (handler).
The first operand for this character specifies the
pointer-encoding (PE) that is used for the second operand,
which specifies the address of the personality routine.
If the augmentation string contains any other characters, the
remainder of the augmentation string should be ignored.
Furthermore, if the size of the augmentation body is unknown
(i.e., 'z' is not the first character of the augmentation string),
then the entire CIE as well all associated FDEs must be ignored.
A Frame Descriptor Entries (FDE) may contain an augmentation body
which, if present, appears right after the "address_range" member
and before the "instructions" member. The contents of this body
is implicitly defined by the augmentation string of the associated
CIE. The meaning of the characters in the CIE's augmentation
string as far as FDEs are concerned is as follows:
'z': The first operand in the FDE's augmentation body specifies
the total length of the augmentation body as a uleb128 (not
counting the length of the uleb128 operand itself).
'L': The operand for this character is an LSDA pointer, encoded
in the format specified by the corresponding operand in the
CIE's augmentation body.

support for C++, but they represent a rather generic way of
describing the format in which an address/pointer is stored and
hence we include the definitions here, in the main dwarf.h file.
The Pointer-Encoding format is partially documented in Linux Base
Spec v1.3 (http://www.linuxbase.org/spec/). The rest is reverse
engineered from GCC.

/* This file defines the runtime-support routines for dynamically
generated code. Even though it is implemented as part of libunwind,
it is logically separate from the interface to perform the actual
unwinding. In particular, this interface is always used in the
context of the unwind target, whereas the rest of the unwind API is
used in context of the process that is doing the unwind (which may be
a debugger running on another machine, for example).
Note that the data-structures declared here server a dual purpose:
when a program registers a dynamically generated procedure, it uses
these structures directly. On the other hand, with remote-unwinding,
the data-structures are read from the remote process's memory and
translated into internalized versions. To facilitate remote-access,
the following rules should be followed in declaring these structures:
(1) Declare a member as a pointer only if the the information the
member points to needs to be internalized as well (e.g., a
string representing a procedure name should be declared as
"const char *", but the instruction pointer should be declared
as unw_word_t).
(2) Provide sufficient padding to ensure that no implicit padding
will be needed on any of the supported target architectures. For
the time being, padding data structures with the assumption that
sizeof (unw_word_t) == 8 should be sufficient. (Note: it's not
impossible to internalize structures with internal padding, but
it does make the process a bit harder).
(3) Don't declare members that contain bitfields or floating-point
values.
(4) Don't declare members with enumeration types. Declare them as
int32_t instead. */

/* Memory pools provide simple memory management of fixed-size
objects. Memory pools are used for two purposes:
o To ensure a stack can be unwound even when a process
is out of memory.
o To ensure a stack can be unwound at any time in a
multi-threaded process (e.g., even at a time when the normal
malloc-lock is taken, possibly by the very thread that is
being unwind).
To achieve the second objective, memory pools allocate memory
directly via mmap() system call (or an equivalent facility).
The first objective is accomplished by reserving memory ahead of
time. Since the memory requirements of stack unwinding generally
depends on the complexity of the procedures being unwind, there is
no absolute guarantee that unwinding will always work, but in
practice, this should not be a serious problem. */
