Merge 'cql3: fix DESCRIBE INDEX WITH INTERNALS name' from Piotr Smaron
This series fixes two related inconsistencies around secondary-index names. 1. `DESCRIBE INDEX ... WITH INTERNALS` returned the backing materialized-view name in the `name` column instead of the logical index name. 2. The snapshot REST API accepted backing table names for MV-backed secondary indexes, but not the logical index names exposed to users. The snapshot side now resolves logical secondary-index names to backing table names where applicable, reports logical index names in snapshot details, rejects vector index names with HTTP 400, and keeps multi-keyspace DELETE atomic by resolving all keyspaces before deleting anything. The tests were also extended accordingly, and the snapshot test helper was fixed to clean up multi-table snapshots using one DELETE per table. Fixes: SCYLLADB-1122 Minor bugfix, no need to backport.

Merge 'db/view/view_building_worker: lock staging sstables mutex for all necessary shards when creating tasks' from Michał Jadwiszczak
To create `process_staging` view building tasks, we firstly need to collect informations about them on shard0, create necessary mutations, commit them to group0 and move staging sstables objects to their original shards. But there is a possible race after committing the group0 command and before moving the staging sstables to their shards. Between those two events, the coordinator may schedule freshly created tasks and dispatch them to the worker but the worker won't have the sstables objects because they weren't moved yet. This patch fixes the race by holding `_staging_sstables_mutex` locks from all necessary shards when executing `create_staging_sstable_tasks()`. With this, even if the task will be scheduled and dispatched quickly, the worker will wait with executing it until the sstables objects are moved and the locks are released. Fixes SCYLLADB-816 This PR should be backported to all versions containing view building coordinator (2025.4 and newer). Closes scylladb/scylladb#29174 * github.com:scylladb/scylladb: db/view/view_building_worker: fix indentation db/view/view_building_worker: lock staging sstables mutex for necessary shards when creating tasks |

cql3: fix DESCRIBE INDEX WITH INTERNALS name
DESCRIBE INDEX ... WITH INTERNALS returned the name of the backing materialized view in the name column instead of the logical index name. Return the logical index name from schema::describe() for index schemas so all callers observe the user-facing name consistently. Fixes: SCYLLADB-1122 |

test: add snapshot REST API tests for logical index names
Add focused REST coverage for logical secondary-index names in snapshot creation, deletion, and details output. Also cover vector-index rejection and verify multi-keyspace delete resolves all keyspaces before deleting anything so mixed index kinds cannot cause partial removal. |

test: fix snapshot cleanup helper
The snapshot REST helper cleaned up multi-table snapshots with a single DELETE request that passed a comma-separated cf filter, but the API accepts only one table name there. Delete each table snapshot separately so existing tests that snapshot multiple tables use the API as documented. |

api: clarify snapshot REST parameter descriptions
Document the current /storage_service/snapshots behavior more accurately. For DELETE, cf is a table filter applied independently in each keyspace listed in kn. If cf is omitted or empty, snapshots for all tables are eligible, and secondary indexes can be addressed by their logical index name. |

api: surface no_such_column_family as HTTP 400

db: fix clear_snapshot() atomicity and use C++23 lambda form
clear_snapshot() applies a table filter independently in each keyspace, so logical index names must be resolved per keyspace on the delete path as well. Resolve all keyspaces before deleting anything so a later failure cannot partially remove a snapshot, and use the explicit-object-parameter coroutine lambda form for the asynchronous implementation. |

db: normalize index names in get_snapshot_details()
Snapshot details exposed backing secondary-index view names instead of logical index names. Normalize index entries in get_snapshot_details() so the REST API reports the user-facing name, and update the existing REST test to assert that behavior directly. |

db: add resolve_table_name() to snapshot_ctl
The snapshot REST API accepted backing secondary-index table names, but not logical index names. Introduce resolve_table_name() so snapshot creation can translate a logical index name to the backing table when the index is materialized as a view. |

strong consistency: replace local consistency with global
Currently we don't support 'local' consistency, which would imply maintaining separate raft group for each dc. What we support is actually 'global' consistency -- one raft group per tablet replica set. We don't plan to support local consistency for the first GA. Closes scylladb/scylladb#29221 |

Merge 'raft: include demoted voters in read barrier during joint config' from Qian Cheng
Hi, thanks for Scylla! We found a small issue in tracker::set_configuration() during joint consensus and put together a fix. When a server is demoted from voter to non-voter, set_configuration processes the current config first (can_vote=false), then the previous config. But when it finds the server already in the progress map (tracker.cc:118), it hits `continue` without updating can_vote. So the server's follower_progress::can_vote stays false even though it's still a voter in the previous config. This causes broadcast_read_quorum (fsm.cc:1055) to skip the demoted server, reducing the pool of responders. Since committed() correctly includes the server in _previous_voters for quorum calculation, read barriers can stall if other servers are slow. The fix is to use configuration::can_vote() in tracker::set_configuration. We included a reproduction unit test (test_tracker_voter_demotion_joint_config) that extracts the set_configuration algorithm and demonstrates the mismatch. We weren't able to build the full Scylla test suite to add an in-tree test, so we kept it as a standalone file for reference. No backport: the bug is non-critical and the change needs some soak time in master. Closes scylladb/scylladb#29226 * https://github.com/scylladb/scylladb: fix: use is_voter::yes instead of true in test assertions test: add tracker voter demotion test to fsm_test.cc fix: use configuration::can_vote() in tracker::set_configuration |

test: fix flaky test_create_index_synchronous_updates trace event race
The test_create_index_synchronous_updates test in test_secondary_index_properties.py was intermittently failing with 'assert found_wanted_trace' because the expected trace event 'Forcing ... view update to be synchronous' was missing from the trace events returned by get_query_trace(). Root cause: trace events are written asynchronously to system_traces.events. The Python driver's populate() method considers a trace complete once the session row in system_traces.sessions has duration IS NOT NULL, then reads events exactly once. Since the session row and event rows are written as separate mutations with no transactional guarantee, the driver can read an incomplete set of events. Evidence from the failed CI run logs: - The entire test (CREATE TABLE through DROP TABLE) completed in ~300ms (01:38:54,859 - 01:38:55,157) - The INSERT with tracing happened in a ~50ms window between the second CREATE INDEX completing (01:38:55,108) and DROP TABLE starting (01:38:55,157) - The 'Forcing ... synchronous' trace message is generated during the INSERT write path (db/view/view.cc:2061), so it was produced, but not yet flushed to system_traces.events when the driver read them - This matches the known limitation documented in test/alternator/ test_tracing.py: 'we have no way to know whether the tracing events returned is the entire trace' Fix: replace the single-shot trace.events read with a retry loop that directly queries system_traces.events until the expected event appears (with a 30s timeout). Use ConsistencyLevel.ONE since system_traces has RF=2 and cqlpy tests run on a single-node cluster. The same race condition pattern exists in test_mv_synchronous_updates in test_materialized_view.py (which this test was modeled after), so the same fix is proactively applied there as well.

scripts/base36-uuid: dump date in UTC
Previously, the timestamp decoded from a timeuuid was printed using the local timezone via datetime.fromtimestamp(), which produces different output depending on the machine's locale settings. ScyllaDB logs are emitted in UTC by default. Printing the decoded date in UTC makes it straightforward to correlate SSTable identifiers with log entries without having to mentally convert timezones. Also fix the embedded pytest assertion, which was accidentally correct only on machines in UTC+8 — it now uses an explicit UTC-aware datetime.

api: Fix enable_injection to accept case-insensitive bool parameter
Replace strict case-sensitive '== "True"' check with strcasecmp(..., "true")
so that Python's str(True) -> "True" is properly recognized. Accepts any
case variation of "true" ("True", "TRUE", etc.), with empty string
defaulting to false.
Maintains backward compatibility with out-of-tree tests that rely on
Python's bool stringification.
The goal is to reduce the number of distinct ways API handlers use to
convert string http query parameters into bool variables. This place is the
only one that simply compares param to "True".

abseil: update to lts_2026_01_07
Switch to branch lts_2026_01_07, which is exactly equal to upstream now.

schema: Avoid copies in column_mapping::operator==
In a multi-declarator declaration, the & ref-qualifier is part of each
individual declarator, not the shared type specifier. So:
const auto& a = x(), b = y();
declares 'a' as a reference but 'b' as a value, silently copying y().
The same applies to:
const T& a = v[i], b = v[j];
Both operator== lines had this pattern, causing an unnecessary copy of
the column vector and an unnecessary copy of each entry on every call.
Fix by repeating & on the second declarator in both lines.

test/pylib: add typed skip markers plugin
Add skip_reason_plugin.py — a framework-agnostic pytest plugin that provides typed skip markers (skip_bug, skip_not_implemented, skip_slow, skip_env) so that the reason a test is skipped is machine-readable in JUnit XML and Allure reports. Bare untyped pytest.mark.skip now triggers a warning (to become an error after full migration). Runtime skips via skip() are also enriched by parsing the [type] prefix from the skip message. The plugin is a class (SkipReasonPlugin) that receives the concrete SkipType enum and an optional report_callback from conftest.py, keeping it decoupled from allure and project-specific types. Extract SkipType enum and convenience runtime skip wrappers (skip_bug, skip_env, etc.) into test/pylib/skip_types.py so callers only need a single import instead of importing both SkipType and skip() separately. conftest.py imports SkipType from the new module and registers the plugin instance unconditionally (for all test runners). New files: - test/pylib/skip_reason_plugin.py: core plugin — typed marker processing, bare-skip warnings, JUnit/Allure report enrichment (including runtime skip() parsing via _parse_skip_type helper) - test/pylib/skip_types.py: SkipType enum and convenience wrappers (skip_bug, skip_not_implemented, skip_slow, skip_env) - test/pylib_test/test_skip_reason_plugin.py: 17 pytester-based test functions (51 cases across 3 build modes) covering markers, warnings, reports, callbacks, and skip_mode interaction Infrastructure changes: - test/conftest.py: import SkipType from skip_types, register SkipReasonPlugin with allure report callback - test/pylib/runner.py: set SKIP_TYPE_KEY/SKIP_REASON_KEY stash keys for skip_mode so the report hook can enrich JUnit/Allure with skip_type=mode without longrepr parsing - test/pytest.ini: register typed marker definitions (required for --strict-markers even when plugin is not loaded) Migrated test files (representative samples): - test/cluster/test_tablet_repair_scheduler.py: skip -> skip_bug (#26844), skip -> skip_not_implemented - test/cqlpy/.../timestamp_test.py: skip -> skip_slow - test/cluster/dtest/schema_management_test.py: skip -> skip_not_implemented - test/cluster/test_change_replication_factor_1_to_0.py: skip -> skip_bug (#20282) - test/alternator/conftest.py: skip -> skip_env - test/alternator/test_https.py: use skip_env() wrapper Fixes SCYLLADB-79 Closes scylladb/scylladb#29235 |

Merge 'storage: implement sstable clone for object storage' from Ernest Zaslavsky
This patch series implements `object_storage_base::clone`, which was previously a stub that aborted at runtime. Clone creates a copy of an sstable under a new generation and is used during compaction. The implementation uses server-side object copies (S3 CopyObject / GCS Objects: rewrite) and mirrors the filesystem clone semantics: TemporaryTOC is written first to mark the operation as in-progress, component objects are copied, and TemporaryTOC is removed to commit (unless the caller requested the destination be left unsealed). The first two patches fix pre-existing bugs in the underlying storage clients that were exposed by the new clone code path: - GCS `copy_object` used the wrong HTTP method (PUT instead of POST) and sent an invalid empty request body. - S3 `copy_object` silently ignored the abort_source parameter. 1. **gcp_client: fix copy_object request method and body** — Fix two bugs in the GCS rewrite API call. 2. **s3_client: pass through abort_source in copy_object** — Stop ignoring the abort_source parameter. 3. **object_storage: add copy_object to object_storage_client** — New interface method with S3 and GCS implementations. 4. **storage: add make_object_name overload with generation** — Helper for building destination object names with a different generation. 5. **storage: make delete_object const** — Needed by the const clone method. 6. **storage: implement object_storage_base::clone** — The actual clone implementation plus a copy_object wrapper. 7. **test/boost: enable sstable clone tests for S3 and GCS** — Re-enable the previously skipped tests. A test similar to `sstable_clone_leaving_unsealed_dest_sstable` was added to properly test the sealed/unsealed states for object storage. Works for both S3 and GCS. Fixes: https://scylladb.atlassian.net/browse/SCYLLADB-1045 Prerequisite: https://github.com/scylladb/scylladb/pull/28790 No need to backport since this code targets future feature Closes scylladb/scylladb#29166 * github.com:scylladb/scylladb: compaction_test: enable sstable clone tests for S3 and GCS storage: implement object_storage_base::clone storage: make delete_object const in object_storage_base storage: add make_object_name overload with generation sstables: add get_format() accessor to sstable object_storage: add copy_object to object_storage_client s3_client: pass through abort_source in copy_object gcp_client: fix copy_object request method and body |

lwt, vector: write to CDC when vector index is enabled.
The vector-search feature introduced the somewhat confusing feature of
enabling CDC without explicitly enabling CDC: When a vector index is
enabled on a table, CDC is "enabled" for it even if the user didn't
ask to enable CDC.
For this, write-path code began to use a new cdc_enabled() function
instead of checking schema.cdc_options.enabled() directly. This
cdc_enabled() function checks if either this enabled() is true, or
has_vector_index() is true.
Unfortunately, LWT writes continued to use cdc_options.enabled() instead
of the new cdc_enabled(). This means that if a vector index is used and
a vector is written using an LWT write, the new value is not indexed.
This patch fixes this bug. It also adds a regression test that fails
before this patch and passes afterwards - the new test verifies that
when a table has a vector index (but no explicit CDC enabled), the CDC
log is updated both after regular writes and after successful LWT writes.
This patch was also tested in the context of the upcoming vector-search-
for-Alternator pull request, which has a test reproducing this bug
(Alternator uses LWT frequently, so this is very important there).
It will also be tested by the vector-store test suite ("validator").
