Inline comments:
In `@contrib/tici-search-lib/CMakeLists.txt`:
- Line 5: Update the LIB_SOURCE_FILES definition in the CMake configuration to
track all Cargo workspace inputs recursively with CONFIGURE_DEPENDS, including
manifests, lockfiles, build scripts, toolchain files, and nested Rust sources,
so changes trigger the Cargo build and refresh TICI_LIB.
In `@dbms/src/Flash/BatchCoprocessorHandler.cpp`:
- Around line 55-57: The disaggregated-compute bypass currently trusts
client-supplied table_shard_infos instead of validating that the DAG contains an
actual TiCI scan. In dbms/src/Flash/BatchCoprocessorHandler.cpp lines 55-57 and
dbms/src/Flash/CoprocessorHandler.cpp lines 102-104, parse and validate the
DAG’s TiCI scan before allowing the request, use the validated camelCase
condition isTiCIScan consistently, and remove reliance on metadata presence
alone.
In `@dbms/src/Flash/Coprocessor/RemoteRequest.h`:
- Around line 74-75: Change the return types of Coprocessor::printRetryRegions
and Coprocessor::printShards, including their definitions, from std::string to
the project’s String type from Core/Types.h.
Apply the same fix in `@dbms/src/Flash/Coprocessor/RemoteRequest.cpp` at line 220:
The implementation must use the same repository type as the declarations.
In `@dbms/src/Flash/Coprocessor/StorageTantivyInterpreter.cpp`:
- Around line 126-128: Replace the TiFlashException thrown in the remote-read
validation path with DB::Exception using an appropriate ErrorCodes value,
preserving the existing “No coprocessor tasks built for remote read” message.
Reuse a matching existing error code, or add one through the project’s
ErrorCodes.cpp and errors.toml definitions if none fits.
- Around line 64-67: Update the remote-read handling around remote_shard_infos
so those shards are not added to DAGContext::retry_shards when the remote read
succeeds. Move or condition the retry_shards insertion to occur only on the
failure path where the remote read cannot complete, preserving retry reporting
for genuinely failed remote reads.
In `@dbms/src/Flash/Coprocessor/StorageTantivyInterpreter.h`:
- Line 37: Rename the class declaration from StorageTantivyIterpreter to
StorageTantivyInterpreter in
dbms/src/Flash/Coprocessor/StorageTantivyInterpreter.h:37-37. Update all
qualified method definitions and references in
dbms/src/Flash/Coprocessor/StorageTantivyInterpreter.cpp:39-39 to use the
corrected class name; no other changes are needed.
In `@dbms/src/Flash/Coprocessor/TiCIScan.h`:
- Around line 35-38: Update TiCIScan’s table_id and index_id storage and
accessors to use Int64, preserving the protobuf int64 widths when passed to
buildCopTaskForFullText. Change limit and its accessor to UInt32 to match
FTSQueryInfo::top_k, without narrowing conversions.
In `@dbms/src/Flash/Planner/Plans/PhysicalBinary.h`:
- Line 51: Implement PhysicalBinary::setChild to replace the left child when the
index is 0 and the right child when the index is 1, and throw an exception for
any other index; preserve the existing child pointer types and avoid the
unconditional unsupported-operation throw.
In `@dbms/src/Flash/Planner/Plans/PhysicalUnary.h`:
- Line 52: Update setChild to reject a null new_child before assigning it to
child, preserving the constructor’s non-null invariant and ensuring children(0)
never exposes an invalid pointer.
In `@dbms/src/Flash/Statistics/ExecutorStatisticsCollector.cpp`:
- Line 99: The executor statistics profile mapping must support TypeIndexScan so
valid leaf traversal does not produce a missing profile. Update the
TypeIndexScan handling in
dbms/src/Flash/Statistics/ExecutorStatisticsCollector.cpp at lines 99-99, then
restore setChildren(children) at lines 117-117 in the tree profile construction
so child relationships are retained; both changes belong in the
ExecutorStatisticsCollector flow.
- Line 232: The fill_local_ru logic in ExecutorStatisticsCollector must continue
after locating the target summary so local RU consumption is validated and
serialized; remove or restructure the early return at the target-summary branch
while preserving the existing fallback behavior, ensuring every local execution
summary includes ru_consumption.
In `@dbms/src/Server/MetricsPrometheus.cpp`:
- Line 101: Update the metrics setup around gather_prometheus_metrics and the
gateway registration so TiCI metrics are exported when status_metrics_addr is
configured without status_metrics_port; register equivalent TiCI collectables
with the gateway, or retain a pull endpoint for this push-only configuration,
while preserving existing pull and push behavior.
In `@dbms/src/Storages/KVStore/TiKVHelpers/PDTiKVClient.h`:
- Around line 141-150: Update the CacheOnly branch in PDTiKVClient’s safepoint
retrieval flow to track whether the keyspace or global cache is initialized and
fresh before returning it. On a miss, uninitialized entry, or stale value, use
the existing coalesced refresh path or reject the request instead of returning
zero or an outdated safepoint; preserve observe_backoff_count behavior and valid
cache-only returns.
In `@dbms/src/Storages/Tantivy/TantivyInputStream.h`:
- Around line 194-198: In the return-column assembly loop, validate every
installed column’s size against search_result.row_count, including columns
populated from values or offsets and those handled by fillDefaultColumn. Reject
or fail immediately when a column length differs, while preserving the existing
default-filling behavior for unfilled columns.
In `@tests/fullstack-test/run.sh`:
- Line 29: Replace every hardcoded docker-compose invocation with the configured
${COMPOSE} command in tests/fullstack-test/run.sh (line 29),
tests/fullstack-test2/run.sh (line 29), and tests/tidb-ci/run.sh (line 28),
covering cluster startup, test execution, and cleanup while preserving each
command’s existing arguments.

- Around line 891-897: Update GetEstimateTiCICount around
EstimateTiCICountHandler::execute to record tiflash_coprocessor_request_count
and tiflash_coprocessor_handling_request_count, and add a Stopwatch with
SCOPE_EXIT to observe request duration, matching the existing Compact and
EstablishDisaggTask instrumentation patterns.
In `@dbms/src/Flash/Planner/Plans/PhysicalTiCIScan.cpp`:
- Around line 41-48: Replace both TiFlashException throws in the scan schema
validation paths with DB::Exception using the fmt-style constructor, and select
the appropriate existing ErrorCodes value defined in ErrorCodes.cpp and
errors.toml. Preserve the current formatted messages and exception behavior
while updating the required includes or namespace references.
In `@dbms/src/Operators/TantivyReaderSourceOp.h`:
- Around line 47-56: Remove the unused block_queue member and popFromBlockQueue
declaration from TantivyReaderSourceOp. For io_profile_info, either initialize
it in the constructor so getIOProfileInfo returns a valid profile, or remove the
override and member to use the base-class default.
In `@dbms/src/Storages/Tantivy/TiCIRequestUtils.h`:
- Around line 182-186: Replace the three std::runtime_error throws for
unsupported or malformed pushed-down expressions in TiCIRequestUtils with
TiFlashException, using Errors::Coprocessor::BadRequest consistently with the
existing bad-request throws in the same file. Preserve each existing formatted
error message and update only the exception type and required classification.

Track all Rust build inputs.
LIB_SOURCE_FILES contains only immediate children of contrib/tici/src. It does not track Cargo.toml, Cargo.lock, build scripts, or rust-toolchain.toml. Changes to these files can leave ${TICI_LIB} up to date, so Cargo does not run and TiFlash links a stale artifact.
Use recursive CONFIGURE_DEPENDS tracking for the Cargo workspace, or use an explicit build stamp.

Validate an actual TiCI scan before the disaggregated-compute bypass.
table_shard_infos is client-supplied metadata. Its presence does not prove that the DAG contains a TiCI scan. A normal DAG can add this field and bypass the compute-node restriction.

Export TiCI metrics in push-only deployments.
gather_prometheus_metrics() is used only by MetricHandler. When status_metrics_addr is set and status_metrics_port is absent, this server does not start the pull handler, while the gateway registers only TiFlash collectables. TiCI metrics are then absent from Prometheus.
Register equivalent TiCI metrics with the gateway, or preserve a pull endpoint for this configuration.

Reject an uninitialized or stale cache-only safepoint.
CacheOnly returns 0 for a keyspace cache miss and returns cached values without a freshness check. StorageDeltaMerge::checkStartTs uses this result to validate reads. A read can then accept a start_ts below PD's current GC safepoint after startup or during an idle refresh gap.
The normal safe_point_update_interval_seconds check is bypassed on this path. The shown refreshers depend on storage work or the schema task interval, which defaults to 60 seconds. Track cache initialization and freshness. Refresh through a coalesced path, or reject the read, before returning an invalid cache-only value.

Validate that each returned column has row_count values.
fillDefaultColumn pads unfilled columns to row_count, but the columns built from search_result use values.size() or offsets.size() as their own length. If TiCI returns a column with a different length than search_result.row_count, the block holds columns of unequal size. The failure then surfaces later as an opaque error or as wrong results in a downstream operator.
Add a length check per installed column against row_count.

- Around line 274-275: In the MPP dispatch error path, replace the std::string
construction for extra_msg with the project-standard String and fmt::format, and
update the throw in the surrounding executor logic to use DB::Exception with the
appropriate ErrorCodes value and fmt-style arguments while preserving the
existing RPC error message and address context.
In `@dbms/src/Storages/S3/S3Common.cpp`:
- Line 259: Rename the local variable extra_msg to extraMsg and update its use
in the adjacent call on line 260, preserving the existing behavior.

Use the project-standard exception and string constructors.
At Line 274, use String with fmt::format instead of std::string concatenation. At Line 275, throw Exception with an appropriate ErrorCodes value and fmt-style arguments.
As per coding guidelines, **/*.cpp must use DB::Exception with an error code and fmt-style constructor, plus String and fmt::format for string construction.

Rename the new local to extraMsg.
The new local extra_msg uses snake_case. Rename it to extraMsg and update the argument on Line 260.
As per coding guidelines, method and variable names in C++ files should use camelCase.
