optimized_clang.sh trains the compiler using profile-guided optimization
(pgo). However, while doing that, it builds scylladb using its own profile
stored in pgo/profiles and decompressed into build/profile.profdata. Due
to the funky directory structure used for training the compiler, that
path is invalid during the training and the build fails.
The workaround was to build on a cloud machine instead of a workstation -
this worked because the cloud machine didn't have git-lfs installed, and
therefore did not see the stored profile, and the whole mess was averted.
To make this work on a machine that does have access to stored profiles,
disable use of the stored profile even if it exists.

Currently, the base_info may or may not be set in view schemas.
Even when it's set, it may be modified. This necessitates extra
checks when handling view schemas, as well as potentially causing
errors when we forget to set it at some point.
Instead, we want to make the base info an immutable member of view
schemas (inside view_info). The first step towards that is making
sure that all newly created schemas have the base info set.
We achieve that by requiring a base schema when constructing a view
schema. Unfortunately, this adds complexity each time we're making
a view schema - we need to get the base schema as well.
In most cases, the base schema is already available. The most
problematic scenario is when we create a schema from mutations:
- when parsing system tables we can get the schema from the
database, as regular tables are parsed before views
- when loading a view schema using the schema loader tool, we need
to load the base additionally to the view schema, effectively
doubling the work
- when pulling the schema from another node - in this case we can
only get the current version of the base schema from the local
database
Additionally, we need to consider the base schema version - when
we generate view updates the version of the base schema used for
reads should match the version of the base schema in view's base
info.
This is achieved by selecting the correct (old or new) schema in
`db::schema_tables::merge_tables_and_views` and using the stored
base schema in the schema_registry.

Any empty object of the json::json_list type has its internal
_set variable assigned to false which results in such objects
being skipped by the json::json_builder.
Hence, the json returned by the api GET//compaction_manager/compaction_history
does not contain the field `rows_merged` if a cell in the
system.compaction_history table is null or an empty list.
In such cases, executing the command `nodetool compactionhistory`
will result in a crash with the following error message:
`error running operation: rjson::error (JSON assert failed on condition 'false'`
The patch fixes it by checking if the json object contains the
`rows_merged` element before processing. If the element does
not exist, the nodetool will now produce an empty list.

Add a new nodetool cluster super-command. Add nodetool
cluster repair command to repair tablet keyspaces.
It uses the new /storage_service/tablets/repair API.
The nodetool cluster repair command allows you to specify
the keyspace and tables to be repaired. A cluster repair of many
tables will request /storage_service/tablets/repair and wait for
the result synchronously for each table.
The nodetool repair command, which was previously used to repair
keyspaces of any type, now repairs only vnode keyspaces.

GetInt() was observed to fail when the integer JSON value overflows the
int32_t type, which `GetInt()` uses for storage. When this happens,
rapidjson will assign a distinct 64 bit integer type to the value, and
attempting to access it as 32 bit integer triggers the wrong-type error,
resulting in assert failure. This was hit on the field where invoking
nodetool netstats resulted in nodetool crashing when the streamed bytes
amounts were higher than maxint.
To avoid such bugs in the future, replace all usage of GetInt() in
nodetool of GetInt64(), just to be sure.
A reproducer is added to the nodetool netstats crash.

Said fields in statistics are of type
`disk_array<uint32_t, disk_string<uint16_t>>` and currently are handled
as array of regular strings. However these fields store exploded
clustering keys, so the elements store binary data and converting to
string can yield invalid UTF-8 characters that certain JSON parsers (jq,
or python's json) can choke on. Fix this by treating them as binary and
using `to_hex()` to convert them to string. This requires some massaging
of the json_dumper: passing field offset to all visit() methods and
using a caller-provided disk-string to sstring converter to convert disk
strings to sstring, so in the case of statistics, these fields can be
intercepted and properly handled.
While at it, the type of these fields is also fixed in the
documentation.

We still have a number of issues to be solved for views with tablets.
Until they are fixed, we should prevent users from creating them,
and use the vnode-based views instead.
This patch prepares the feature for enabling views with tablets. The
feature is disabled by default, but currently it has no effect.
After all tests are adjusted to use the feature, we should depend
on the feature for deciding whether we can create materialized views
in tablet-enabled keyspaces.
The unit tests are adjusted to enable this feature explicitly, and it's
also added to the scylla sstable tool config - this tool treats all
tables as if they were tablet-based (surprisingly, with SimpleStrategy),
so for it to work on views, the new feature must be enabled.

Replace usages of `boost::algorithm::join()` with `fmt::join()` to improve
performance and reduce dependency on Boost. `fmt::join()` allows direct
formatting of ranges and tuples with custom separators without creating
intermediate strings.
When formatting comma-separated values into another string, fmt::join()
avoids the overhead of temporary string creation that
`boost::algorithm::join()` requires. This change also helps streamline
our dependencies by leveraging the existing fmt library instead of
Boost.Algorithm.
To avoid the ambiguity, some caller sites were updated to call
`seastar::format()` explicitly.

Artifact tests have been failing since the switch to the native nodetool, because ScyllaDB doesn't leave any IOCBs for tools. On some setups it will consume all of them and then nodetool and any other native app will refuse to start because it will fail to allocate IOCBs.
This PR fixes this by making use of the freshly introduced `--reserve-io-control-blocks` seastar option, to reserve IOCBs for tool applications. Since the `linux-aio` and `epoll` reactor backends require quite a bit of these, we enable the `io_uring` reactor backend and switch tools to use this backend instead. The `io_uring` reactor backend needs just 2 IOCBs to function, so the reserve of 10 IOCBs set up in this PR is good for running 5 tool applications in parallel, which should be more than enough.

With commits ed7d352e7d and bb1867c7c7, we now have input streams for both compressed and uncompressed SSTables that provide seamless checksum and digest checking. The code for these was based on `validate_checksums()`, which implements its own validation logic over raw streams. This has led to some duplicate code.
This PR deduplicates the uncompressed case by modifying `validate_checksums()` to use a checksummed input stream instead of a raw stream. The same cannot be done for compressed SSTables though. The reason is that `validate_checksums()` needs to examine the whole data file, even if an invalid chunk is encountered. In the checksummed case we support that by offloading the error handling logic from the data source via a function parameter. In the compressed data source we cannot do that because it needs to return decompressed data and decompression may fail if the data are invalid.
This PR also enables `validate_checksums()` to partially verify SSTables with just the per-chunk checksums if the digest is missing.
In more detail, this PR consists of:
* Port of some integrity checks from `do_validate_uncompressed()` to the checksummed data source. It should now be able to detect corruption due to truncated or appended chunks (expected number of chunks is retrieved from the CRC component).
* Introduction of `error_handler` parameter in checksummed data source and `data_stream()`.
* Refactoring of `validate_checksums()`. The JSON response of `sstable validate-checksums` was also modified to report a missing digest.
* Tests for `validate_checksums()` against SSTables with truncated data, appended data, invalid digests, or no digest.

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.

Currently the locator::topology object, when created, does not contain
local node, but it is started to be used to access local database. It
sort of work now because there are explicit checks in the code to handle
this special case like in topology::get_location for instance. We do not
want to hack around it and instead rely on an invariant that the local
node is always there. To do that we add local node during
locator::topology creation. There is a catch though. Unlike with IP host
ID is not known during startup. We actually need to read from the
database to know it, so the topology starts with host ID zero and then
it changes once to the real one. This is not a problem though. As long as
the (one node) topology is consistent (_cfg.this_host_id is equal to the
node's id) local access will work.

that when these options are used, they won't define where the tool will
attempt to load the schema from, they will just be helpers to help locate
the schema, for whichever schema source the tool was instructed to use
(or left to choose).
--scylla-data-dir and --scylla-yaml-file being schema sources were
problematic with encryption at rest and for S3 support (not yet
implemented). With encryption, the tool needs access to the
configuration, so --scylla-yaml-file is often used to provide the path
to the configuration file, which contains encryption configuration,
needed for the tool to decrypt the sstable. Currently, using this option
implies forcing the tool to read the schema from the schema tables,
which is a problematic option for tests -- Scylla might be compacting a
schema sstable and this will make the tool fail to load the schema.
Demoting these options the schema helpers, allows providing them, while
at the same time having the option to use a different schema-source.
To allow the user to force the tool to load the schema from the schema
tables, a new --schema-tables option is added. Similarly, a
--sstable-schema option is introduced to force the tool to load the
schema from the sstable itself.
With this, each 4 schema source now has an option to force the use of
said schema source. There are various helper options to be used along
with these.
The documentation as well as the tests are updated with the changes.
The schema related documentation gets an rather extensive facelift
because it was a bit out-of-date and incomplete.

When users start an operation asynchronously with API, they are expected to check the operation's status. Hence, the status should be kept in task manager for reasonable time after the operation is done. The operations that are started internally usually don't need to stay in task manager for that long.
Add api_task_ttl that will be used for tasks started with API. By default it's 1 hour. The time for which non-API tasks stay in task manager isn't changed.
Fixes: #21499.
Refs: #21425.
No backport needed - previous versions may use task_ttl

Modernize the codebase by replacing Boost range adaptors with C++23 standard library views,
reducing external dependencies and leveraging modern C++ language features.
Key Changes:
- Replace `boost::adaptors::filtered` with `std::views::filter`
- Remove `#include <boost/range/adaptor/filtered.hpp>`
- Utilize standard library range views
Motivation:
- Reduce project's external dependency footprint
- Leverage standard library's range and view capabilities
- Improve long-term code maintainability
- Align with modern C++ best practices
Implementation Challenges and Considerations:
1. Range Conversion and Move Semantics
- `std::ranges::to` adaptor requires rvalue references
- Necessitated updates to variable and parameter constness
- Example: `cql3/restrictions/statement_restrictions.cc` modified to remove `const`
from `common` to enable efficient range conversion
2. Range Iteration and Mutation
- Range views may mutate internal state during iteration
- Cannot pass ranges by const reference in some scenarios
- Solution: Pass ranges by rvalue reference to explicitly indicate
state invalidation
Limitations:
- One instance of `boost::adaptors::filtered` temporarily preserved
due to lack of a C++23 alternative for `boost::join()`
- A comprehensive replacement will be addressed in a follow-up change
This change is part of our ongoing effort to modernize the codebase,
reducing external dependencies and adopting modern C++ practices.

The `sstable validate-checksums` tool provides the validation result
via the `valid_checksums` key in its JSON response.
The name can be misleading as it refers to both the per-chunk checksums
and the digest (full checksum). We use the terms "digest" and
"full checksum" interchangeably.
Replace with the word "valid" to avoid confusion.

Currently, `validate_checksums()` expects the SSTable to have a digest
component and fails immediately otherwise. This is suboptimal since data
integrity verification could still be carried out partially via checksum
checking.
Lift this restriction by allowing the function to perform checksum
checking in any case, and treat digest checking as best effort. Add a
separate boolean flag in the response to indicate the presence or
absence of the digest component, so that the user can deduce if a valid
result involved digest checking or not.
