c575bbf1e8 test_refresh_deletes_uploaded_sstables should wait for sstables to get deleted
SSTable unlinking is async, so in some cases it may happen that
the upload dir is not empty immediately after refresh is done.
This patch adjusts test_refresh_deletes_uploaded_sstables so
it waits with a timeout till the upload dir becomes empty
instead of just assuming the API will sync on sstables being
gone.

7fdd650009 Merge 'test: audit: clean up test helper class naming' from Dario Mirovic
Remove unused `pytest.mark.single_node` marker from `TestCQLAudit`.

Rename `TestCQLAudit` to `CQLAuditTester` to reflect that it is a test helper, not a test class. This avoids accidental pytest collection and subsequent warning about `__init__`.

552a2d0995 test: audit: rename TestCQLAudit to CQLAuditTester
pytest tries to collect tests for execution in several ways.
One is to pick all classes that start with 'Test'. Those classes
must not have custom '__init__' constructor. TestCQLAudit does.

TestCQLAudit after migration from test/cluster/dtest is not a test
class anymore, but rather a helper class. There are two ways to fix
this:
1. Add __init__ = False to the TestCQLAudit class
2. Rename it to not start with 'Test'

Option 2 feels better because the new name itself does not convey
the wrong message about its role.

f988ec18cb test/lib: fix port in-use detection in start_docker_service
Previously, the result of when_all was discarded. when_all stores
exceptions in the returned futures rather than throwing, so the outer
catch(in_use&) could never trigger. Now we capture the when_all result
and inspect each future individually to properly detect in_use from
either stream.

cd1679934c test/pylib: use exponential backoff in wait_for()
Change wait_for() defaults from period=1s/no backoff to period=0.1s
with 1.5x backoff capped at 1.0s. This catches fast conditions in
100ms instead of 1000ms, benefiting ~100 call sites automatically.

Add completion logging with elapsed time and iteration count.

d52fbf7ada Merge 'test: cluster: Deflake test_startup_with_keyspaces_violating_rf_rack_valid_keyspaces' from Dawid Mędrek
The test was flaky. The scenario looked like this:

1. Stop server 1.
2. Set its rf_rack_valid_keyspaces configuration option to true.
3. Create an RF-rack-invalid keyspace.
4. Start server 1 and expect a failure during start-up.

It was wrong. We cannot predict when the Raft mutation corresponding to
the newly created keyspace will arrive at the node or when it will be
processed. If the check of the RF-rack-valid keyspaces we perform at
start-up was done before that, it won't include the keyspace. This will
lead to a test failure.

Unfortunately, it's not feasible to perform a read barrier during
start-up. What's more, although it would help the test, it wouldn't be
useful otherwise. Because of that, we simply fix the test, at least for
now.

The new scenario looks like this:

1. Disable the rf_rack_valid_keyspaces configuration option on server 1.
2. Start the server.
3. Create an RF-rack-invalid keyspace.
4. Perform a read barrier on server 1. This will ensure that it has
   observed all Raft mutations, and we won't run into the same problem.
5. Stop the node.
6. Set its rf_rack_valid_keyspaces configuration option to true.
7. Try to start the node and observe a failure.

This will make the test perform consistently.

141aa2d696 Merge 'test/cluster/test_incremental_repair.py: fix typo + enable compaction DEBUG logs' from Botond Dénes
This PR contains two small improvements to `test_incremental_repair.py`
motivated by the sporadic failure of
`test_tablet_incremental_repair_and_scrubsstables_abort`.

The test fails with `assert 3 == 2` on `len(sst_add)` in the second
repair round. The extra SSTable has `repaired_at=0`, meaning scrub
unexpectedly produced more unrepaired SSTables than anticipated. Since
scrub (and compaction in general) logs at DEBUG level and the test did
not enable debug logging, the existing logs do not contain enough
information to determine the root cause.

**Commit 1** fixes a long-standing typo in the helper function name
(`preapre` -> `prepare`).

**Commit 2** enables `compaction=debug` for the Scylla nodes started by
`do_tablet_incremental_repair_and_ops`, which covers all
`test_tablet_incremental_repair_and_*` variants. This will capture full
compaction/scrub activity on the next reproduction, making the failure
diagnosable.

c670183be8 cmake: fix precompiled header (PCH) creation
Two issues prevented the precompiled header from compiling
successfully when using CMake directly (rather than the
configure.py + ninja build system):

a) Propagate build flags to Rust binding targets reusing the
   PCH. The wasmtime_bindings and inc targets reuse the PCH
   from scylla-precompiled-header, which is compiled with
   Seastar's flags (including sanitizer flags in
   Debug/Sanitize modes). Without matching compile options,
   the compiler rejects the PCH due to flag mismatch (e.g.,
   -fsanitize=address). Link these targets against
   Seastar::seastar to inherit the required compile options.

503a6e2d7e locator: everywhere_replication_strategy: fix sanity_check_read_replicas when read_new is true
ERMs created in `calculate_vnode_effective_replication_map` have RF computed based
on the old token metadata during a topology change. The reading replicas, however,
are computed based on the new token metadata (`target_token_metadata`) when
`read_new` is true. That can create a mismatch for EverywhereStrategy during some
topology changes - RF can be equal to the number of reading replicas +-1. During
bootstrap, this can cause the
`everywhere_replication_strategy::sanity_check_read_replicas` check to fail in
debug mode.

We fix the check in this commit by allowing one more reading replica when
`read_new` is true.

ffd58ca1f0 Merge 'test: cluster: Deflake test_write_cl_any_to_dead_node_generates_hints' from Dawid Mędrek
Before these changes, we would send mutations to the node and
immediately query the metrics to see how many hints had been written.
However, that could lead to random failures of the test: even if the
mutations have finished executing, hints are stored asynchronously, so
we don't have a guarantee they have already been processed.

To prevent such failures, we rewrite the check: we will perform multiple
checks against the metrics until we have confirmed that the hints have
indeed been written or we hit the timeout.

We're generous with the timeout: we give the test 60 seconds. That
should be enough time to avoid flakiness even on super slow machines,
and if the test does fail, we will know something is really wrong.

As a bonus, we improve the test in general too. We explicitly express
the preconditions we rely on, as well as bump the log level. If the
test fails in the future, it might be very difficult do debug it
without this additional information.

Migrate audit tests from test/cluster/dtest to test/cluster. Optimize their execution time through cluster reuse.

The audit test suite is heavy. There are more than 70 test executions. Environment preparation is a significant part of each test case execution time.

This PR:
1. Copies audit tests from test/cluster/dtest to test/cluster, refactoring and enabling them
2. Groups tests functions by non-live cluster configuration variations to enable cluster reuse between them
    - Execution time reduced from 4m 29s to 2m 47s, which is ~38% execution time decrease
3. Removes the old audit tests from test/cluster/dtest

Includes two supporting changes:
- Allow specifying `AuthProvider` in `ManagerClient.get_cql_exclusive`
- Fix server log file handling for clean clusters

120f381a9d pgo: fix maintenance socket path too long
Maintenance socket path used for PGO is in the node workdir.
When the node workdir path is too long, the maintenance socket path
(workdir/cql.m) can exceed the Unix domain socket sun_path limit
and failing the PGO training pipeline.

To prevent this:
- pass an explicit --maintenance-socket override
  pointing to a short determinitic path in /tmp derived from the MD5
  hash of the workdir maintenance socket path
- update maintenance_socket_path to return the matching short path
  so that exec_cql.py connects to the right socket

The short path socket files are cleaned up after the cluster stops.

The path is using MD5 hash of the workdir path, so it is deterministic.

There's a flaw in table::query() -- calling querier_opt->close() can dereferences a disengaged std::optional. The fix pretty simple. Once fixed, there are two if-s checking for querier_opt being engaged or not that are worth being merged.

The problem doesn't really shows itself becase table::query() is not called with null saved_querier, so the de-facto if is always correct. However, better to be on safe-side.

e59a21752d .github/workflows/trigger_jenkins.yaml: add workflow permissions
Potential fix for https://github.com/scylladb/scylladb/security/code-scanning/147.

To fix the problem, add an explicit `permissions:` block to the workflow
(either at the top level or inside the `trigger-jenkins` job) that
constrains the `GITHUB_TOKEN` to the minimal necessary privileges. This
codifies least-privilege in the workflow itself instead of relying on
repository or organization defaults.

The best minimal, non‑breaking change is to define a root‑level
`permissions:` block with read‑only contents access because the job does
not perform any write operations to the repository, nor does it interact
with issues, pull requests, or other GitHub resources. A conservative,
widely accepted baseline is `contents: read`. If later steps require more
permissions, they can be added explicitly, but for this snippet, no such
need is visible.

Concretely, in `.github/workflows/trigger_jenkins.yaml`, insert:

```yaml
permissions:
  contents: read
```

between the `name:` block and the `on:` block (e.g., after line 2).
No additional methods, imports, or definitions are needed since this is
a pure YAML configuration change and does not alter runtime behavior of
the existing shell steps.

85a531819b .github/workflows/trigger-scylla-ci.yaml: add permissions to workflow
Potential fix for https://github.com/scylladb/scylladb/security/code-scanning/169.

In general, the fix is to add an explicit `permissions:` block to the
workflow (at the root level or per job) so that the `GITHUB_TOKEN` has
only the minimal scopes needed. Since this job only reads event data and
uses secrets to talk to Jenkins, we can restrict `GITHUB_TOKEN` to
read‑only repository contents.

The single best fix here is to add a top‑level `permissions:` block
right under the `name:` (and before `on:`) in
`.github/workflows/trigger-scylla-ci.yaml`, setting `contents: read`.
This applies to all jobs in the workflow, including `trigger-jenkins`,
and does not alter any existing steps or logic. No additional imports or
methods are needed, as this is purely a YAML configuration change for
GitHub Actions.

Concretely, edit `.github/workflows/trigger-scylla-ci.yaml` to insert:

```yaml
permissions:
  contents: read
```

after line 1. No other lines in the file need to change.

ae12c712ce test: cluster: Specify min_tablet_count in test_write_cl_any_to_dead_node_generates_hints
The test relies on the assumption that mutations will be distributed
more or less uniformly over the nodes. Although in practice this should
not be possible, theoretically it's possible that there's only one
tablet allocated for the table.

To clearly indicate this precondition, we explicitly set the property
`min_tablet_count` when creating the table. This way, we have a gurantee
that the table has multiple tablets. The load balancer should now take
care of distributing them over the nodes equally. Thanks to that,
`servers[1]` will have some tablets, and so it'll be the target for some
of the mutations we perform.

772b32d9f7 test/scylla_gdb: fix flakiness by preparing objects at test time
Fixtures previously ran GDB once (module scope) to find live objects
(sstables, tasks, schemas) and stored their addresses. Tests then
reused those addresses in separate GDB invocations. Sometimes these
addresses would become stale and the test would step on use-after-free
(e.g. sstables compacted away between invocations).

Fix by dropping the fixtures. The helper functions used by the fixtures
to obtain the required objects are converted to gdb convenience
functions, which can be used in the same expression as the test command
invocation. Thus, the object is aquired on-demand at the moment it is
used, so it is guaranteed to be fresh and relevant.

`std::filesystem::path` directly. Add `.string()` calls in places that
attempt to print paths directly in order to make them work.

3b9398dfc8 Merge 'encryption: fix deadlock in encrypted_data_source::get()' from Ernest Zaslavsky
When encrypted_data_source::get() caches a trailing block in _next, the next call takes it directly — bypassing input_stream::read(), which checks _eof. It then calls input_stream::read_exactly() on the already-drained stream. Unlike read(), read_up_to(), and consume(), read_exactly() does not check _eof when the buffer is empty, so it calls _fd.get() on a source that already returned EOS.

In production this manifested as stuck encrypted SSTable component downloads during tablet restore: the underlying chunked_download_source hung forever on the post-EOS get(), causing 4 tablets to never complete. The stuck files were always block-aligned sizes (8k, 12k) where _next gets populated and the source is fully consumed in the same call.

Fix by checking _input.eof() before calling read_exactly(). When the stream already reached EOF, buf2 is known to be empty, so the call is skipped entirely.

A comprehensive test is added that uses a strict_memory_source which fails on post-EOS get(), reproducing the exact code path that caused the production deadlock.

Fixes: https://scylladb.atlassian.net/browse/SCYLLADB-1128

Backport to 2025.3/4 and 2026.1 is needed since it fixes a bug that may bite us in production, to be on the safe side

f5438e0587 test/cluster/test_incremental_repair.py: enable compaction DEBUG logs in do_tablet_incremental_repair_and_ops
The test sporadically fails because scrub produces an unexpected number
of SSTables. Compaction logs are needed to diagnose why, but were not
captured since scrub runs at DEBUG level. Enable compaction=debug for
the servers started by do_tablet_incremental_repair_and_ops so the next
reproduction provides enough information to root-cause the issue.

051107f5bc scylla-gdb: fix sstable-summary crash on ms-format sstables
The 'scylla sstable-summary' GDB command crashes with
'ValueError: Argument "count" should be greater than zero' when
inspecting ms-format (trie-based) sstables. This happens because
ms-format sstables don't populate the traditional summary structure,
leaving all fields zeroed out, which causes gdb.read_memory() to be
called with a zero count.

Fix by:
- Adding zero-length guards to sstring.to_hex() and sstring.as_bytes()
  to return early when the data length is zero, consistent with the
  existing guard in managed_bytes.get().
- Adding the same guard to scylla_sstable_summary.to_hex().
- Detecting ms-format sstables (version == 5) early in
  scylla_sstable_summary.invoke() and printing an informative message
  instead of attempting to read the unpopulated summary.

c8e7e20c5c test/cluster: retry create_table on transient schema agreement timeout
In test_index_requires_rf_rack_valid_keyspace, the create_table call
for a plain tablet-based table can fail with 'Unable to reach schema
agreement' after the server's 10s timeout is exceeded. This happens
when schema gossip propagation across the 4-node cluster takes longer
than expected after a sequence of rapid schema changes earlier in the
test.

Add a retry (up to 2 attempts) on schema agreement errors for this
specific create_table call rather than increasing the server-side
timeout.

fb1f995d6b .github/workflows/backport-pr-fixes-validation.yaml: workflow does not contain permissions (Potential fix for code scanning alert no. 139)
Potential fix for https://github.com/scylladb/scylladb/security/code-scanning/139,

To fix the problem, explicitly restrict the `GITHUB_TOKEN` permissions
for this workflow/job so it has only what is needed. The script reads PR
data and repository info (which is covered by `contents: read`/default
read scopes) and posts a comment via `github.rest.issues.createComment`,
which requires `issues: write`. No other write scopes (e.g., `contents:
write`, `pull-requests: write`) are necessary.

The best fix without changing functionality is to add a `permissions`
block scoped to this job (or at the workflow root). Since we only see a
single job here, we’ll add it under `check-fixes-prefix`. Concretely, in
`.github/workflows/backport-pr-fixes-validation.yaml`, between the
`runs-on: ubuntu-latest` line (line 10) and `steps:` (line 11), add:

```yaml
    permissions:
      contents: read
      issues: write
```

This keeps the token minimally privileged while still allowing the script
to create issue/PR comments.

32225797cd dtest: fix flaky test_writes_schema_recreated_while_node_down
`read_barrier(session2)` was supposed to ensure `node2` has caught up on schema
before a CL=ALL write. But `patient_cql_connection(node2)` creates a
cluster-aware driver session `(TokenAwarePolicy(DCAwareRoundRobinPolicy()))`
that can route the barrier CQL statement to any node — not necessarily `node2`.
If the barrier runs on `node1` or `node3` (which already have the new schema),
it's a no-op, and `node2` remains stale, thus the observed `WriteFailure`.
The fix is to switch to `patient_exclusive_cql_connection(node2)`,
which uses `WhiteListRoundRobinPolicy([node2_ip])` to pin all CQL to `node2`.
This is already the established pattern used by other tests in the same file.

f29525f3a6 test/boost/cache_algorithm_test: disable sstable compression to avoid giant index pages
The test intentionally creates huge index pages.
But since 5e7fb08bf3,
the index reader allocates a block of memory for a whole index page,
instead of incrementally allocating small pieces during index parsing.
This giant allocation causes the test to fail spuriously in CI sometimes.

Fix this by disabling sstable compression on the test table,
which puts a hard cap of 2000 keys per index page.

05b11a3b82 sstables_loader: use new sstable add path
Use add_new_sstable_and_update_cache() when attaching SSTables
downloaded by the node-scoped local loader.

This is the correct variant for new SSTables: it can unlink the
SSTable on failure to add it, and it can split the SSTable if a
tablet split is in progress. The older
add_sstable_and_update_cache() helper is intended for preexisting
SSTables that are already stable on disk.

Additionally, downloaded SSTables are now left unsealed (TemporaryTOC)
until they are successfully added to the table's SSTable set. The
download path (download_fully_contained_sstables) passes
leave_unsealed=true to create_stream_sink, and attach_sstable opens
the SSTable with unsealed_sstable=true and seals it only inside the
on_add callback — matching the pattern used by stream_blob.cc and
storage_service.cc for tablet streaming.

This prevents a data-resurrection hazard: previously, if the process
crashed between download and attach_sstable, or if attach_sstable
failed mid-loop, sealed (TOC) SSTables would remain in the table
directory and be reloaded by distributed_loader on restart. With
TemporaryTOC, sstable_directory automatically cleans them up on
restart instead.

cc695bc3f7 Merge 'vector_search: fix race condition on connection timeout' from Karol Nowacki
When a `with_connect` operation timed out, the underlying connection
attempt continued to run in the reactor. This could lead to a crash
if the connection was established/rejected after the client object had
already been destroyed. This issue was observed during the teardown
phase of a upcoming high-availability test case.

This commit fixes the race condition by ensuring the connection attempt
is properly canceled on timeout.

Additionally, the explicit TLS handshake previously forced during the
connection is now deferred to the first I/O operation, which is the
default and preferred behavior.

Fixes: SCYLLADB-832

9c1c41df03 table: don't close a disengaged querier in query()
The condition guarding querier_opt->close() was:

When saved_querier is null the short-circuit makes the whole condition true
regardless of whether querier_opt is engaged.  If partition_ranges is empty,
query_state::done() is true before the while-loop body ever runs, so querier_opt
is never created.  Calling querier_opt->close() then dereferences a disengaged
std::optional — undefined behaviour.

Fix by checking querier_opt first:

This preserves all existing semantics (close when not saving, or when saving
wouldn't be useful) while making the no-querier path safe.

Why this doesn't surface today: the sole production call site, database::query(),
in practice.  The API header documents nullptr as valid ("Pass nullptr when
queriers are not saved"), so the bug is real but latent.
