This should significantly reduce the MemoryTracking drift, test shows
that there is 0 drift after query storm (100 queries, via http/tcp/tcp
in one session).
TL;DR;
To track memory, clickhouse creates memory tracker object for each
thread **explicitly**, but until it is not created the memory
allocations are not under account.
There should not be lot of allocations w/o memory tracker, since most of
the time it is created early enough, but even this maybe enough to
trigger some problems.
Plus sometimes it is not possible to create it, for example some 3d
party library does not allow to do this explicitly:
- for example before #15740 allocations from librdkafka threads,
- or even worse, poco threads, they don't have any routines to do this.
This won't be a problem for `MemoryTracking` metric if the deallocation
will be done from the same thread w/o memory tracker (or vise versa),
but this is not always true.
NOTE, that this will slow down per-thread allocations w/o memory
tracker, since before this patch there were no memory tracking for them
while now they will be accounted in total_memory_tracker, and for
total_memory_tracker max_untracked_memory is always reached.
But this should not be significant.
jemalloc relies on working MADV_DONTNEED (that fact that after
madvise(MADV_DONTNEED) returns success, after subsequent access to those
pages they will be zeroed).
However qemu does not support this, yet [1], and you can get very tricky
assert if you will run clickhouse-server under qemu:
<jemalloc>: ../contrib/jemalloc/src/extent.c:1195: Failed assertion: "p[i] == 0"
[1]: https://patchwork.kernel.org/patch/10576637/
But after this patch you will get pretty error:
$ qemu-x86_64-static programs/clickhouse
MADV_DONTNEED does not zeroed page. jemalloc will be broken

With '\n...' after the query [1] clickhouse-client prefer data from the
INSERT over from stdin, and produce very tricky message:
Code: 27. DB::Exception: Cannot parse input: expected '\n' before: ' ': (at row 1)
Well for TSV it is ok, but for RowBinary:
Code: 33. DB::Exception: Cannot read all data. Bytes read: 1. Bytes expected: 4.
So improve error message by adding the source of data for INSERT.
[1]: clickhouse-client -q "INSERT INTO data FORMAT TSV\n " <<<2
Add inter-server cluster secret, it is used for Distributed queries
inside cluster, you can configure in the configuration file:
<remote_servers>
<logs>
<shard>
<secret>foobar</secret> <!-- empty -- works as before -->
...
</shard>
</logs>
</remote_servers>
And this will allow clickhouse to make sure that the query was not
faked, and was issued from the node that knows the secret. And since
trust appeared it can use initial_user for query execution, this will
apply correct *_for_user (since with inter-server secret enabled, the
query will be executed from the same user on the shards as on initator,
unlike "default" user w/o it).
v2: Change user to the initial_user for Distributed queries if secret match
v3: Add Protocol::Cluster package
v4: Drop Protocol::Cluster and use plain Protocol::Hello + user marker
v5: Do not use user from Hello for cluster-secure (superfluous)
Add distributed_ddl.pool_size to control maximum parallel to handle
distributed DDL.
Also:
- convert Exception constructors to fmt-like
- use sleepFor* over std::this_thread::sleep_for()
Process query until the stage where the aggregate functions were
calculated and finalized.
It will be used for optimize_distributed_group_by_sharding_key.
v2: fix aliases
v3: Fix protocol ABI breakage due to WithMergeableStateAfterAggregation
Conditions >= for QueryProcessingStage::Enum has been verified, and they
are ok (in InterpreterSelectQuery).
Functions to encrypt/decrypt any input data with OpenSSL's ciphers
with custom key, iv, and add (-gcm mode only).
_mysql versions are 100% compatitable with corresponding MySQL functions
Supported modes depend on OpenSSL version, but generally are:
aes-{128,192,56}-{ecb,cbc,cfb1,cfb8,cfb128,ofb,gcm}
Please note that in a -gcm mode a 16-byte tag is appended to the ciphertext
on encryption and is expected to be found at the end of ciphertext on decryption.
Added tests that verify compatibility with MySQL functions,
and test vectors for GCM mode from OpenSSL.
Added masking rules for aes_X funtions
Rules are installed by default to config.d/query_masking_rules.xml
