af8eaa9ea5 scripts: fixes flagged by CodeQL/PyLens
Unused imports, unused variables and such.
Initially, there were no functional changes, just to get rid of some standard CodeQL warnings.

I've then broken the CI, as apparently there's a install time(!?) Python script creation for the sole purpose of product
naming. I changed it - we have it in etcdir, as SCYLLA-PRODUCT-FILE.
So added (copied from a different script) a get_product() helper function in scylla_util.py and used it instead.

While at it, also fixed the too broad import from scylla_util, which 'forced' me to also fix other specific imports (such as shutil).

Improvement - no need to backport.

60570d7114 Merge 'topology coordinator: restrict node join/remove to preserve RF-rack validity' from Michael Litvak
Allow creating materialized views and secondary indexes in a tablets keyspace only if it's RF-rack-valid, and enforce RF-rack-validity while the keyspace has views by restricting some operations:
* Altering a keyspace's RF if it would make the keyspace RF-rack-invalid
* Adding a node in a new rack
* Removing / Decommissioning the last node in a rack

Previously the config option `rf_rack_valid_keyspaces` was required for creating views. We now remove this restriction - it's not needed because we always maintain RF-rack-validity for keyspaces with views.

The restrictions are relevant only for keyspaces with numerical RF. Keyspace with rack-list-based RF are always RF-rack-valid.

Fixes scylladb/scylladb#23345

4c9c3aae23 tools: toolchain: add dockerfile for future toolchain
To avoid surprises when libstdc++, clang, or other components
in the toolchain introduce regressions, we introduce a "future
toolchain". This builds on the Fedora version under active
development, and the development branches of gcc and llvm.

The future toolchain is not intended to be frozen. Rather,
periodically we will build the future toolchain, then build
ScyllaDB and run its unit tests under that toolchain, then
discard it. Any problems will then have be be tracked down
by a developer and either reported to the source repository,
or fixed in ScyllaDB.

b690ddb9e5 tools: toolchain: dbuild: bind-mount full ~/.cache to container
In afb96b6387, we added support for sccache. As a side effect
it changed the method of invoking ccache from transparent via PATH
(if it contains /usr/lib64/ccache) to explicit, by changing the compiler
command line from 'clang++' (which may or may not resolve the the ccache
binary) to 'ccache /usr/local/bin/clang++', which always invokes ccache.

In the default dbuild configuration, PATH does not contain /usr/lib64/ccache,
so ccache isn't invoked by default. Users can change this via the
SCYLLADB_DBUILD environment variable.

As a result of ccache being suddenly enabled for dbuild builds, ccache
will now attempt to create ~/.cache/ccache. Under docker, this does
not work, because we bind-mount ~/.cache/dbuild. Docker will create the
intermediate ~/.cache, but under the root user, not $USER. The intermediate
directory being root-owned prevents ~/.cache/ccache from being created.

Under podman, this does work, because everything runs under the container's
root user.

The fix is to bind-mount the entire ~/.ccache into the container. This
not only lets ccache create the directory, it will also find an existing
~/.cache/ccache directory and use it, enabling reuse across invocations.

Since ccache will now respect configuration changes without access to
its configuration file (notably, the maximum cache size), we also
bind-mount ~/.config.

Since ~/.ccache and ~/.config are not automatically created, we create
them explicitly so the bind mounts can work. This is for new nodes enlisted
from the cloud; developer machines will have those directories preexisting.

Note that the ccache directory used to be ~/.ccache, but was later changed.
Had the author known, we would have bind-mounted ~/.cache much earlier.

Fixes #27919.

bfdd4f7776 Merge 'Synchronize incremental repair and tablet split' from Raphael Raph Carvalho
Split prepare can run concurrently with repair.

Consider this:

1) split prepare starts
2) incremental repair starts
3) split prepare finishes
4) incremental repair produces unsplit sstable
5) split is not happening on sstable produced by repair
        5.1) that sstable is not marked as repaired yet
        5.2) might belong to repairing set (has compaction disabled)
6) split executes
7) repairing or repaired set has unsplit sstable

If split was acked to coordinator (meaning prepare phase finished),
repair must make sure that all sstables produced by it are split.
It's not happening today with incremental repair because it disables
split on sstables belonging to repairing group. And there's a window
where sstables produced by repair belong to that group.

To solve the problem, we want the invariant where all sealed sstables
will be split.
To achieve this, streaming consumers are patched to produce unsealed
sstable, and the new variant add_new_sstable_and_update_cache() will
take care of splitting the sstable while it's unsealed.
If no split is needed, the new sstable will be sealed and attached.

This solution was also needed to interact nicely with out of space
prevention too. If disk usage is critical, split must not happen on
restart, and the invariant aforementioned allows for it, since any
unsplit sstable left unsealed will be discarded on restart.
The streaming consumer will fail if disk usage is critical too.

The reason interposer consumer doesn't fully solve the problem is
because incremental repair can start before split, and the sstable
being produced when split decision was emitted must be split before
attached. So we need a solution which covers both scenarios.

Fixes #26041.
Fixes #27414.

Should be backported to 2025.4 that contains incremental repair

06343b58a2 cql3: add warning when creating mv/index with tablets about rf-rack

8df61f6d99 view: change validate_view_keyspace to allow MVs if RF=Racks
The function validate_view_keyspace checks if a keyspace is eligible for
having materialized views, and it is used for validation when creating a
MV or a MV-based index.

Previously, it was required that the rf_rack_valid_keyspaces option is
set in order for tablets-based keyspaces to be considered eligible, and
the RF-rack condition was enforced when the option is set.

Instead of this, we change the validation to allow MVs in a keyspace if
the RF-rack condition is satisfied for the keyspace - regardless of the
config option.

We remove the config validation for views on startup that validates the
option `rf_rack_valid_keyspaces` is set if there are any views with
tablets, since this is not required anymore.

We can do this without worrying about upgrades because this change will
be effective from 2025.4 where MVs with tablets are first out of
experimental phase.

We update the test for MV and index restrictions in tablets keyspaces
according to the new requirements.

* Create MV/index: previously the test checked that it's allowed only if
  the config option `rf_rack_valid_keyspaces` is set. This is changed
  now so it's always allowed to create MV/index if the keyspace is
  RF-rack-valid. Update the test to verify that we can create MV/index
  when the keyspace is RF-rack-valid, even if the rf_rack option is not
  set, and verify that it fails when the keyspace is RF-rack-invalid.
* Alter: Add a new test to verify that while a keyspace has views, it
  can't be altered to become RF-rack-invalid.

3f7ee3ce5d Merge 'batchlog: make replay (flush) faster' from Botond Dénes
The batchlog table contains an entry for each logged batch that is processed by the local node as coordinator. These entries are typically very short lived, they are inserted when the batch is processed and deleted immediately after the batch is successfully applied.
When a table has `tombstone_gc = {'mode': 'repair'}` enabled, every repair has to flush all hints and batchlogs, so that we can be certain that there is no live data in any of these, older than the last repair. Since batches can contain member queries from any number of tables, the whole batchlog has to be flushed, even if repair-mode tombstone-gc is enabled for a single table.

Flushing the batchlog table happens by doing a batchlog replay. This involves reading the entire content of this table, and attempting to replay+delete any live entries (that are old enough to be replayed).  Under normal operating circumstances, 99%+ of the content of the batchlog table is partition tombstones.  Because of this, scanning the content of this table has to process thousands to millions of tombstones. This was observed to require up to 20 minutes to finish, causing repairs to slow down to a crawl, as the batchlog-flush has to be repeated at the end of the repair of each token-range.

When trying to address this problem, the first idea was that we should expedite the garbage-collection of these accumulated tombstones. This experiment failed, see https://github.com/scylladb/scylladb/pull/23752. The commitlog proved to be an impossible to bypass barrier, preventing quick garbage-collection of tombstones. So long as a single commit-log segment is alive, holding content from the batchlog table, all tombstones written after are blocked from GC.
The second approach, represented by this PR, is to not rely in tombstone GC to reduce the tombstone amount. Instead restructure the table such that a single higher-order tombstone can be used to shadow and allow for the eviction of the myriads of individual batchlog entry tombstones. This is realized by reorganizing the batchlog table such that individual batches are rows, not partitions.
This new schema is introduced by the new `system.batchlog_v2` table, introduced by this PR:

    CREATE TABLE system.batchlog_v2 (
        version int,
        stage int,
        shard int,
        written_at timestamp,
        id uuid,
        data blob,
        PRIMARY KEY ((version, stage, shard), written_at, id));

The new schema organization has the following goals:
1) Make post-replay batchlog cleanup possible with a simple range-tombstone. This allows dropping the individual dead batchlog entries, as they are shadowed by a higher level tombstone. This enables dropping tombstones without tombstone GC.
2) To make the above possible, introduce the stage key component: batchlog entries that fail the first replay attempt, are moved to the failed_replay stage, so the initial stage can be cleaned up safely.
3) Spread out the data among Scylla shards, via the batchlog shard column.
4) Make batchlog entries ordered by the batchlog create time (id). This allows for selecting batchlogs to replay, without post-filtering of batchlogs that are too young to be replayed.

Fixes: https://github.com/scylladb/scylladb/issues/23358

This is an improvement, normally not a backport-candidate. We might override this and backport to allow wider use of `tombstone_gc: {'mode': 'repair'}`.

This reverts commit 8192f45e84.

The merge exposed a bug where truncate (via drop) fails and causes Raft
errors, leading to schema inconsistencies across nodes. This results in
test_table_drop_with_auto_snapshot failures with 'Keyspace test does not exist'
errors.

The specific problematic change was in commit 19b6207f which modified
truncate_table_on_all_shards to set use_sstable_identifier = true. This
causes exceptions during truncate that are not properly handled, leading
to Raft applier fiber stopping and nodes losing schema synchronization.

80c6718ea8 build: update toolchain to Fedora 43 with clang 21.1.6
Rebase to Fedora 43 with clang 21.1 and libstdc++ 15.

Fedora container image registry moved to registry.fedoraproject.org as
it seems to be updated more regularly.

Added python3-devel to the dependencies as some packages scylla-cqlsh
depends on aren't yet available in the form of wheels for Python 3.14,
and so have to be built locally. In any case it's better to reduce
dependency on those wheels even if the ones currently missing appear
eventually.

Added libev-devel to the dependencies so that the python driver
builds correctly even if "wheels" are not published. This reduces
our dependency on the python driver's binary release schedule.
Without libev-devel, TLS does not work correctly.

We no long remove the clang and clang-libs packages. Doxygen
started depending on clang-libs, and removing them removes
doxygen, breaking the build when it looks for that. The build
will still pick up the optimized clang, since /usr/local/bin
is earlier in the path. We keep the clang package, since it allows
us to mess a little less with the directory structure.

Optimized clang binaries generates and stored in

8192f45e84 Merge 'Add option to use sstable identifier in snapshot' from Benny Halevy
This change adds a new option to the REST api and correspondingly, to scylla nodetool: use_sstable_identifier.
When set, we use the sstable identifier, if available, to name each sstable in the snapshots directory
and the manifest.json file, rather than using the sstable generation.

This can be used by the user (e.g. Scylla Manager) for global deduplication with tablets, where an sstable
may be migrated across shards or across nodes, and in this case, its generation may change, but its
sstable identifier remains sstable.

Currently, Scylla manager uses the sstable generation to detect sstables that are already backed up to
object storage and exist in previous backed up snapshots.
Historically, the sstable generation was guaranteed to be unique only per table per node,
so the dedup code currently checks for deduplication in the node scope.

However, with tablet migration, sstables are renamed when migrated to a different shard,
i.e. their generation changes, and they may be renamed when migrated to another node,
but even if they are not, the dedup logic still assumes uniqueness only within a node.

To address both cases, we keep the sstable_id stable throughout the sstable life cycle (since 3a12ad96c7).
Given the globally unique sstable identifier, scylla manager can now detect duplicate sstables
in a wider scope.  This can be cluster-wide, but we practically need only rack-wide deduplication
or dc-wide, as tablets are migrated across racks only in rare occasions (like when converting from a
numerical replication factor to a rack list containing a subset of the available racks in a datacenter).

45c16553eb Revert "Update tools/cqlsh submodule"
This reverts commit ff1b212319. In this
commit, the python driver was updated to 3.29.6. That version has a
serious flaw - it rejects compression=None settings [1] which
cqlsh (legitimately) uses in copyutil.py.

The reason this hasn't caused numerous continuous integration failures
is that the submodule update commit did not update the frozen toolchain,
so the build was effectively running with an older version of the driver.

Fix by reverting the change. This allows us to regenerate the frozen
toolchain when we need to.

866c96f536 Merge 'Add digests for all sstable components in scylla metadata' from Taras Veretilnyk
This pull request adds support for calculation and storing CRC32 digests for all SSTable components.
This change replaces plain file_writer with crc32_digest_file_writer for all SSTable components that should be checksummed. The resulting component digests are stored in the sstable structure
and later persisted to disk as part of the Scylla metadata component during writer::consume_end_of_stream.
All important SSTable components (Index, Partitions, Rows, Summary, Filter, CompressionInfo, and TOC) are covered.
Several test cases where introduced to verify expected behaviour.

Backport is not required, it is a new feature

584f4e467e tools/scylla-sstable: introduce the dump-schema command
There is a limited number of ways to obtain the schema of a table:
1) Use DESCRIBE TABLE in cqlsh
2) Find the schema definition in the code (for system tables)
3) Ask support/user to provide schema
4) Piece together the schema definition from the system tables

Option (1) is the most convenient but requires access to live cluster.
(2) is limited to system tables only.
When investigating issues for customers, we have to rely on (3) and this
often adds communication round-trips and delays. (4) requires knowledge
of ScyllaDB internals and access to system tables.

The new dump-schema commands provides a convenient way to obtain the
schema of tables, given that there is access to either an sstable or the
system tables. It can dump the schema of system tables without either.

bcd1758911 Merge 'vector_search: add validator tests' from Pawel Pery
The vector-search-validator is a binary tool which do functional and integration tests between scylla and vector-store. It is build in Rust mainly in vector-store repository. This patch adds possibility to write tests on scylladb repository side, compile them together with vector-store tests and run them in `test.py` environment.

There are three parts of the change:

- add sources of validator to the `test/vector_search_validator` directory
- add support for building validator and vector-store in `build/vector-search-validator/bin` directory with or without cmake
- add support for `pytest` and `test.py` to run validator test locally and in the CI environment; this part adds also README to the `test/vector_search_validator` directory

Design for validator integration tests: https://scylladb.atlassian.net/wiki/spaces/RND/pages/39518215/Vector+Search+Core+Test+Plan+Document

eb5e9f728c build: lock cxxbridge-cmd version to the rest of the cxx packages
rust/Cargo.toml locks the cxx packages to version 1.0.83,
but install-dependencies.sh does not lock cxxbridge-cmd, part
of that ecosystem. Since cxx 1.0.189 broke compatibility with
1.0.83 (understandable, as these are all sub-packages of a single
repository), builds with newer cxxbridge-cmd are broken.

Fix by locking cxxbridge-cmd to the same version as the other
cxx subpackages.

Regenerated frozen toolchain with optimized clang from
    https://devpkg.scylladb.com/clang/clang-20.1.8-Fedora-42-aarch64.tar.gz
    https://devpkg.scylladb.com/clang/clang-20.1.8-Fedora-42-x86_64.tar.gz

linux headers and zlib.

The feature is enabled by default, use CMake option `Scylla_USE_PRECOMPILED_HEADER`
or configure.py --disable-precompiled-header to disable.

The feature should be disabled, when trying to check headers - otherwise
you might get false negatives on missing includes from seastar / abseil and so on.

0cc5208f8e Merge 'Add sstables_manager::config' from Pavel Emelyanov
Currently sstables_manager keeps a reference on global db::config to configure itself. Most of other services use their own specific configs with much less data on-board for the same purposes (e.g. #24841, #19051 and #23705 did same for other services) This PR applies this approach to sstables_manager as well.

Mostly it moves various values from db::config onto newly introduced struct sstables_manager::config, but it also adds specific tracking of sstable_file_io_extensions and patches tools/scylla-sstable not to use sstables_manager as "proxy" object to get db::config from along its calls.
