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)
