bdcf965318 test: Move B-tree compactiont test from unit to boost
This test must run in seastar thread, so put it in seastar-thread test
case, fortunately btree test allows that. Just like its stress peer,
this test also has two invocations from suite, so make it two distinct
test cases as well.

1213f02a5a test: skip test_lwt_semaphore::test_cas_semaphore in aarch64 debug mode
The test configures write timeout to much smaller value to make the test
run faster since for some writes sleep is inserted to hit the timeout,
but it makes aarch64 debug flaky since timeout happens when it should
not because of a natural slowness.

d1c7e2effa configure.py: deduplicate --out-final-name arg added in build.ninja
Every time the ninja buildfile decides it needs to be updates, it calls
the configure.py script with roughly the same set of flags. However, the
--out-final-name flag is improperly handled and, on each reconfigure,
one more --out-final-name flag is appended to the rebuild command. This
is harmless because each instance of the flag will specify the same
parameter, but slightly annoying because it bloats the generated file
and the duplicated flags show up in ninja's output when reconfigure
runs.

Fix the problem by stripping the --out-final-name flags from the set of
the flags passed to the configure.py before forwarding them to the
reconfigure rule.

6496eab5ee Merge 'Rename Alternator batch item count metrics' from Amnon Heiman
This PR addresses multiple issues with alternator batch metrics:

1. Rename the metrics to scylla_alternator_batch_item_count with op=BatchGetItem/BatchWriteItem
2. The batch size calculation was wrong and didn't count all items in the batch.
3. Add a test to validate that the metrics values increase by the correct value (not just increase). This also requires an addition to the testing to validate ops of different metrics and an exact value change.

Needs backporting to allow the monitoring to use the correct metrics names.

fdc8773278 test/scylla_gdb: get table::_schema raw pointer with lw_shared_ptr
This commit addresses an issue where accessing the raw pointer of the
schema instance within `table::_schema` using `table.schema._p` was
unreliable.

before this change, `_p` was of type `lw_shared_ptr_counter_base*`, a
type-erased smart pointer, preventing direct casting to the underlying
schema pointer. but we still cast it to `schema*` anyway. this led to
a gdb.MemoryError when dereferencing the deduced pointer:
but the type of `_p` is `lw_shared_ptr_counter_base*`, which is a
type erased smart pointer, and it cannot be casted directly to the
under pointer pointing to a `schema` instance. this results in:

```
Traceback (most recent call last):
  File "/home/avi/scylla/test/scylla_gdb/../../scylla-gdb.py", line 5554, in invoke
    self.print_key_type(seastar_lw_shared_ptr(schema['_clustering_key_type']).get().dereference(), 'clustering')
  File "/home/avi/scylla/test/scylla_gdb/../../scylla-gdb.py", line 5533, in print_key_type
    key_type = seastar_shared_ptr(key_type).get().dereference()
               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
gdb.MemoryError: Cannot access memory at address 0x4000079656b0078
```

when we are dereferencing the raw pointer deduced this way.

in this change,

* we use the wrapper of `seastar_lw_shared_ptr` to safely obtain the
  raw pointer.
* reenable this test previously disabled by 3d781c4f

657848dcbb cql3: statement_restrictions, expr: move restrictions-related expression utilities out of expression.cc
Move all of the blatantly restriction-related expression utilities
to statement_restrictions.cc.

Some are so blatant as to include the word "restriction" in their name.
Others are just so specialized that they cannot be used for anything else.

The motivation is that further refactoring will be simplified if it can
happen within the same module, as there will not be a need to prove
it has no effect elsewhere.

Most of the declarations are made non-public (in .cc file) to limit
proliferation. A few are needed for tests or in select_statement.cc
and so are kept public.

Other than that, the only changes are namespace qualifications and
removal of a now-duplicate definition ("inclusive").

  > Merge 'build.xml: install and use java-11 when building' from Kefu Chai

Updates to clang 18.1.8 + LLVM patch to match Fedora 40.

New optimized clang build generated and stored in

    https://devpkg.scylladb.com/clang/clang-18.1.8-x86_64.tar.gz
    https://devpkg.scylladb.com/clang/clang-18.1.8-aarch64.tar.gz

Due to the loss of the jmx submodule, we no longer install java-11-openjdk.
We add it in install-dependencies.sh here to compensate, pending a better
solution.

tools/java submodule updated to remove build failure where Java 8
was selected instead of Java 11.

The scylla_gdb test suite was disabled due to a regression in gdb 15,
which is brought in by the toolchain update [1].

488a372fdc tool/scylla-nodetool: status: reorder endpoint calls to match old nodetool
Old nodetool requested `/storage_service/tokens_endpoing` first, then
`/storage_service/host_id`, while the native nodetool did it in reverse
order. Most of the time this is inconsequential but there is an edge
case when a node's IP address is changed. This reversing of the order
results in unexpected behavior for tests, causing noise via flaky
tests.
Match the order of the old nodetool so that the native nodetool exhibits
the behavior expected by tests (and users too probably).

but "next patch" doesn't use it outside of the filesystem-storage

This field doesn't make sense for S3 backend. Its "location" is not
location, but a key in the system.sstables, which should rather be
schema ID, not /var/lib/.../keyspace/table-uuid string.

3499c407f7 test: avoid silly "no_mode.1" labels when running tests outside test.py
For the benefit of running test.py inside CI, we recently added to
test/cql-pytest and test/alternator the knowledge of which "Scylla mode"
(--mode) and "run number" is running (--run_id), although these concepts
are alien to these two test frameworks (remember that those test frameworks
can also run tests against unknown versions of Scylla or even our competitors'
implementations).

One unfortunate result of this change is that now if you run a test by
using pytest directly (or test/*/run) instead of test.py, for example:

    $ cd test/alternator
    $ pytest --aws test_item.py::test_basic_string_put_and_get

The test's success or failure reports the ugly name

    test_item.py::test_basic_string_put_and_get.no_mode.1

This unnecessary "no_mode.1" come from the the default values for --mode
and --run_id, respectively. But there is no reason for these silly
defaults. In this patch we change these defaults to None, and when they
are None, they aren't tacked onto the test's name.

This patch shouldn't affect running tests through test.py, because
test.py always sets the --mode and --run_id options, and doesn't leave
them as the default.

bd720dd2da Merge 'cql3: statement_restrictions: adapt to functional style' from Avi Kivity
The statement_restrictions class started life in the object-oriented style - an
object that interacts with its environment via mutators and is observed via
observers.

This is however not suitable for its objective: to analyze the WHERE clause,
select a query plan, and partition the WHERE clause atoms to the various
parts demanded by the query plan (read_command and filters). Furthermore,
the object oriented style makes it hard to work with as you can only call some
observers after the related mutators were called.

Fix this by transforming the code info a more functional style: we call
a function that returns an immutable statement_restrictions object that
can only be observed. This makes it easier to further change in the future,
as changes will not have to consider interaction with the environment.

No backport as this is a refactoring

During a query execution, the query can be re-bounced to another shard if the requested data is located there. Previous implementation assumed that the shard cannot be changed after first re-bounce, however with the introduction of Tablets, data could be migrated to another shard after the query was already re-bounced, causing a failure of the query execution. To avoid this issue, the query is re-bounced as needed until it is executed on the correct shard.

574a08ed96 storage_service: rebuild: warn about tablets-enabled keyspaces
Until we automatically support rebuild for tablets-enabled
keyspaces, warn the user about them.

The reason this is not an error, is that after
increasing RF in a new datacenter, the current procedure
is to run `nodetool rebuild` on all nodes in that dc
to rebuild the new vnode replicas.
This is not required for tablets, since the additional
replicas are rebuilt automatically as part of ALTER KS.

However, `nodetool rebuild` is also run after local
data loss (e.g. due to corruption and removal of sstables).
In this case, rebuild is not supported for tablets-enabled
keyspaces, as tablet replicas that had lost data may have
already been migrated to other nodes, and rebuilding the
requested node will not know about it.
It is advised to repair all nodes in the datacenter instead.

In #15060 we added forced new commitlog segment on user initated flush,
mainly so that tests can verify tombstone gc and other compaction related
things, without having to wait for "organic" segment deletion.
Schema commitlog was not included, mainly because we did not have tests
featuring compaction checks of schema related tables, but also because
it was assumed to be lower general througput.
There is however no real reason to not include it, and it will make some
testing much quicker and more predictable.

eb22c2a8c8 Merge 'reader_concurrency_semaphore: improve the diagnostics dump' from Botond Dénes
* Also dump diagnostics when a read times out while active (not queued).
* Add the "Trigger permit" line, containing the details of the permit which caused the diagnostics dump (by e.g. timing out).
* Add the "Identified bottleneck(s)" line, containing the identified bottlenecks which lead to permits being queued. This line is missing if no such bottleneck can be identified.
* Document the new features, as well as the stat dump, which was added some time ago.

Example of the new dump format:

So the table is not dropped while the query is ongoing.
query() already does this but using old-fashioned enter()+leave(),
convert it to use the new RAII helper.

2f4f0eb060 Merge 'Alternator: a few RBAC fixes' from Nadav Har'El
The main goal of this PR is to fix a bug (#20619) in the alternator_enforce_authorization=false setting - which didn't do its job (i.e, _don't_ check permissions) when authorization is configured in CQL but not wanted in Alternator.

The series also a few smaller bugs in the code that were discovered while debugging the main issue:
1. A potential use-after-free (that didn't seem to hit us in practice) is fixed.
2. A confusing error message (that was also reported in #20619) is improved.
3. Make the alternator_enforce_authorization live-updatable. There was no reason why it shouldn't be, and as this series needs to make this flag available to more code, let's just do it properly and assume the flag is live-updatable.

Because the RBAC feature has not been backported to any open-source branches, neither should these fixes. But if some private branch received a backport of the RBAC feature, it should get these fixes too.

Fixes #20619.

The breaking changes in the seastar submodule necessitate corresponding
modifications in our code. These changes must be implemented together in
a single commit to maintain consistency. So that each commit is buildable.

following changes are included in addition to seastar submodule update:
* instead of passing a `const char*` for the format string, pass a
  templated `fmt::format_string<...>`, this depends on the
  `seastar::format()` change in seastar.
* explicitly call `fmt::runtime()` if the format string is not a
  consteval expression. this depends on the `seastar::format()` change
  in seastar. as `seastar::format()` does not accept a plain
  `const char*` which is not constexpr anymore.
* pass abort_source to `dns_connection_factory::make()`. this depends on
  the change in seastar, which added a `abort_source*` argument to
  the pure virtual member function of `connection_factory::make()`.
* call call {fmt,seastar}::format() explicitly. this is a follow up of
  3e84d43f, which takes care of all places where we should call
  `fmt::format()` and `seastar::format()` explicitly to disambiguate the
  `format()` call. but more `format()` call made their way into the source
   tree after 3e84d43f. so we need fix them as well.
* include used header in tests

4d57a43815 alternator:test_metrics Add validating the increased value
The `check_increases_operation` now allows override the checked metric.

Additionally, a custom validation value can now be passed, which make it
possible to validate the amount by which a value has changed, rather
than just validating that the value increased.

The default behavior of validating that values have increased remains
unchanged, ensuring backward compatibility.

905408f764 alternator: Fix item counting in batch operations
This patch fixes the logic for counting items in batch operations.
Previously, the item count in requests was inaccurate, it count the
number of tabels in get_item and the request_items in write_items.

The new logic correctly counts each individual item in `BatchGetItem`
and `BatchWriteItem` requests.
