We want to drop ips from token_metadata so move to use host id based
counterparts. Messaging service gets a function that maps from ips to id
when is starts listening.
In order to make sure that the scheduling group carries over RPC, and
also to prevent priority inversion issues between different service
levels, modify the messaging service to use separate RPC connections for
each service level in order to serve user traffic.
The above is achieved by reusing the existing concept of "tenants" in
messaging service: when a new service level (or, more accurately,
service-level specific scheduling group) is first used in an RPC, a
new tenant is created.
In addition, extend the service level controller to be able to quickly
look up the service level name of the currently active scheduling group
in order to speed up the logic for choosing the tenant.
This patch sets up an `alien_worker`, `advanced_rpc_compression::tracker`,
`dict_sampler` and `dictionary_service` in `main()`, and wires them to each other
and to `messaging_service`.
`messaging_service` compresses its network traffic with compressors managed by
the `advanced_rpc_compression::tracker`. All this traffic is passed as a single
merged "stream" through `dict_sampler`.
`dictionary_service` has access to `dict_sampler`.
On chosen nodes (by default: the Raft leader), it uses the sampler to maintain
a random multi-megabyte sample of the sampler's stream. Every several minutes,
it copies the sample, trains a compression dictionary on it (by calling zstd's
training library via the `alien_worker` thread) and publishes the new dictionary
to `system.dicts` via Raft.
This update triggers a callback into `advanced_rpc_compression::tracker` on all nodes,
which updates the dictionary used by the compressors it manages.
"
This rather large patch series moves storage proxy and some adjacent
services (like migration manager) to use host ids to identify nodes rather
than ips. Messaging service gains a capability to address nodes by host
ids (which allows dropping translations from topology coordinator code
that worked on host ids already) and also makes sure that a node with
incorrect host id will reject a message (can happen during address
changes).
The series gets rid of the raft address map completely and replaces it with
the gossiper address map which is managed by the gossiper since translation
is now done in the layer below raft.

The later includes the former and in addition to `seastar::format()`,
`print.hh` also provides helpers like `seastar::fprint()` and
`seastar::print()`, which are deprecated and not used by scylladb.
Previously, we include `seastar/core/print.hh` for using
`seastar::format()`. and in seastar 5b04939e, we extracted
`seastar::format()` into `seastar/core/format.hh`. this allows us
to include a much smaller header.

before this change, we build some tests as if they are Seastar tests.
but after 415c83fa, these tests failed to link. because the
Seastar::seastar_testing does not expose `-DSEASTAR_TESTING_MAIN` in
its cflags. the behavior of the Seastar::seastar_testing is expected.
because a test linking against this library is not necessarily driven
by the `main()` provided by `testing/seastar_test.hh`.
so, in this change, we correct the `KIND` parameter of these tests,
so that they use `KIND BOOST`, as these tests can be driven by the
`main()` provided by Boost.Test's driver. also there are some tests
driven by Boost.Test's `main()`, but in the meanwhile, they utilize
seastar_testing, so let's add `Seastar::seastar_testing` to their
`LIBRARIES`.

the log.hh under the root of the tree was created keep the backward
compatibility when seastar was extracted into a separate library.
so log.hh should belong to `utils` directory, as it is based solely
on seastar, and can be used all subsystems.
in this change, we move log.hh into utils/log.hh to that it is more
modularized. and this also improves the readability, when one see
`#include "utils/log.hh"`, it is obvious that this source file
needs the logging system, instead of its own log facility -- please
note, we do have two other `log.hh` in the tree.

Closesscylladb/scylladb#20924
assert() is traditionally disabled in release builds, but not in
scylladb. This hasn't caused problems so far, but the latest abseil
release includes a commit [1] that causes a 1000 insn/op regression when
NDEBUG is not defined.
Clearly, we must move towards a build system where NDEBUG is defined in
release builds. But we can't just define it blindly without vetting
all the assert() calls, as some were written with the expectation that
they are enabled in release mode.
To solve the conundrum, change all assert() calls to a new SCYLLA_ASSERT()
macro in utils/assert.hh. This macro is always defined and is not conditional
on NDEBUG, so we can later (after vetting Seastar) enable NDEBUG in release
mode.

The series adds a step during node's boot process, just before completing
the initialization, in which the node sends a notification to all other
normal nodes in the cluster that it is UP now. Other nodes wait for this
node to be UP and in normal state before replying. This ensures that,
in a healthy cluster, when a node start serving queries the entire
cluster knows its up-to-date state. The notification is a best effort
though. If some nodes are down or do not reply in time the boot process
continues. It is somewhat similar to shutdown notification in this regard.
* 'gleb/notify-up-v2' of github.com:scylladb/scylla-dev:
gossiper: wait for a bootstrapping node to be seen as normal on all nodes before completing initialization
Wait for booting node to be marked UP before complete booting.
gossiper: move gossip verbs to the idl
flat_mutation_reader_v2 was introduced in a pair of commits in 2021:
e3309322c3 "Clone flat_mutation_reader related classes into v2 variants"
08b5773c12 "Adapt flat_mutation_reader_v2 to the new version of the API"
as a replacement for flat_mutation_reader, using range_tombstone_change
instead of range_tombstone to represent represent range tombstones. See
those commits for more information.
The transition was incremental; the last use of the original
flat_mutation_reader was removed in 2022 in commit
026f8cc1e7 "db: Use mutation_partition_v2 in mvcc"
In turn, flat_mutation_reader was introduced in 2017 in commit
748205ca75 "Introduce flat_mutation_reader"
To transition from a mutation_reader that nested rows within
a partition in a separate stream, to a flat reader that streamed
partitions and rows in the same stream.
Here, we reclaim the original name and rename the awkward
flat_mutation_reader_v2 to mutation_reader.
Note that mutation_fragment_v2 remains since we still use the original
for compatibilty, sometimes.
Some notes about the transition:
- files were also renamed. In one case (flat_mutation_reader_test.cc), the
rename target already existed, so we rename to
mutation_reader_another_test.cc.
- a namespace 'mutation_reader' with two definitions existed (in
mutation_reader_fwd.hh). Its contents was folded into the mutation_reader
class. As a result, a few #includes had to be adjusted.
Closesscylladb/scylladb#19356
Currently a node does not wait to be marked UP by other nodes before
complete booting which creates a usability issue: during a rolling restart
it is not enough to wait for local CQL port to be opened before
restarting next node, but it is also needed to check that all other
nodes already see this node as alive otherwise if next node is restarted
some nodes may see two node as dead instead of one.
This patch improves the situation by making sure that boot process does
not complete before all other nodes do not see the booting one as alive.
This is still a best effort thing: if some nodes are unreachable or
gossiper propagation takes too much time the boot process continues
anyway.

before this change, we rely on `seastar/util/std-compat.hh` to
include the used headers provided by stdandard library. this was
necessary before we moved to a C++20 compliant standard library
implementation. but since Seastar has dropped C++17 support. its
`seastar/util/std-compat.hh` is not responsible for providing these
headers anymore.
so, in this change, we include the used headers directly instead
of relying on `seastar/util/std-compat.hh`.

messaging_service.cc depends on idl, but many source files in
scylla-main do no depend on idl, so let's
* move "message/*" into its own directory and add an inter-library
dependency between it and the "idl" library.
* rename the target of "message" under test/manual to "message_test"
to avoid the name collision
this should address the compilation failure of

Gossiper service sets its group0 id on startup if it is stored in `scylla_local`
or sets it during joining group0.
Send group0_id (if it is set) when the node tries to initiate the gossip round.
When a node gets gossip_digest_syn it checks if its group0 id equals the local
one and if not, the message is discarded.
Fixes#14448.
In that level no io_priority_class-es exist. Instead, all the IO happens
in the context of current sched-group. File API no longer accepts prio
class argument (and makes io_intent arg mandatory to impls).
So the change consists of
- removing all usage of io_priority_class
- patching file_impl's inheritants to updated API
- priority manager goes away altogether
- IO bandwidth update is performed on respective sched group
- tune-up scylla-gdb.py io_queues command
The first change is huge and was made semi-autimatically by:
- grep io_priority_class | default_priority_class
- remove all calls, found methods' args and class' fields
Patching file_impl-s is smaller, but also mechanical:
- replace io_priority_class& argument with io_intent* one
- pass intent to lower file (if applicatble)
Dropping the priority manager is:
- git-rm .cc and .hh
- sed out all the #include-s
- fix configure.py and cmakefile
The scylla-gdb.py update is a bit hairry -- it needs to use task queues
list for IO classes names and shares, but to detect it should it checks
for the "commitlog" group is present.

And propagate it down to where it is created. This will be used to add
trace points for semaphore related events, but this will come in the
next patches.
this change is a leftover of 063b3be,
which failed to include the changes in the header files.
it turns out we have `using namespace httpd;` in seastar's
`request_parser.rl`, and we should not rely on this statement to
expose the symbols in `seatar::httpd` to `seastar` namespace.
in this change,
* api/*.hh: all httpd symbols are referenced by `httpd::*`
instead of being referenced as if they are in `seastar`.

they are part of the CQL type system, and are "closer" to types.
let's move them into "types" directory.
the building systems are updated accordingly.
the source files referencing `types.hh` were updated using following
command:
```
find . -name "*.{cc,hh}" -exec sed -i 's/\"types.hh\"/\"types\/types.hh\"/' {} +
```
the source files under sstables include "types.hh", which is
indeed the one located under "sstables", so include "sstables/types.hh"
instea, so it's more explicit.
