177-200: Fix fmt placeholder in logging error; prefer robust parsingThe else branch uses fmt::format with "%s" which won’t substitute loggingLevel. Use {} instead. Also consider spdlog::level::from_str to avoid string literal comparisons.
Apply:
- throw std::runtime_error(fmt::format("Unknown logging level: %s", loggingLevel)); + throw std::runtime_error(fmt::format("Unknown logging level: {}", loggingLevel));Optional parsing refactor:
void configureLogging(const std::string &loggingLevel) { - if (loggingLevel == SPDLOG_LEVEL_NAME_INFO) { - spdlog::set_level(spdlog::level::info); - } else if (loggingLevel == SPDLOG_LEVEL_NAME_DEBUG) { - spdlog::set_level(spdlog::level::debug); - } else if (loggingLevel == SPDLOG_LEVEL_NAME_TRACE) { - spdlog::set_level(spdlog::level::trace); - } else if (loggingLevel == SPDLOG_LEVEL_NAME_OFF) { - spdlog::set_level(spdlog::level::off); - } else { - throw std::runtime_error(fmt::format("Unknown logging level: {}", loggingLevel)); - } + auto lvl = spdlog::level::from_str(loggingLevel); + if (lvl == spdlog::level::off && loggingLevel != SPDLOG_LEVEL_NAME_OFF) { + // from_str returns off on failure; double-check to differentiate real "off" + throw std::runtime_error(fmt::format("Unknown logging level: {}", loggingLevel)); + } + spdlog::set_level(lvl); }
🧹 Nitpick comments (21)
tests/go/kvtest/cmd/root.go (4)
1-3: Replace placeholder copyright.Update “NAME HERE ” with actual author or project copyright/license.
12-25: Make root command user-friendly: show help by default and silence Cobra noise.Set a meaningful description, show help when no subcommands are provided, and silence usage/errors to avoid duplicate output.
Apply:
var rootCmd = &cobra.Command{ - Use: "kvtest", - Short: "A brief description of your application", - Long: `A longer description that spans multiple lines and likely contains -examples and usage of using your application. For example: - -Cobra is a CLI library for Go that empowers applications. -This application is a tool to generate the needed files -to quickly create a Cobra application.`, - // Uncomment the following line if your bare application - // has an action associated with it: - // Run: func(cmd *cobra.Command, args []string) { }, + Use: "kvtest", + Short: "CLI harness for TinyKVPP integration and load tests", + Long: "kvtest exercises TinyKVPP and Raft via gRPC. Use subcommands to run scenarios, load tests, and assertions.", + SilenceUsage: true, + SilenceErrors: true, + RunE: func(cmd *cobra.Command, args []string) error { + // Show help when no subcommands are specified + return cmd.Help() + }, }
6-10: Print error before exiting.Currently Execute() exits with status 1 but doesn’t print the error, which hinders debugging in CI.
Apply:
import ( + "fmt" "os" "github.com/spf13/cobra" )func Execute() { err := rootCmd.Execute() if err != nil { - os.Exit(1) + _, _ = fmt.Fprintln(os.Stderr, err) + os.Exit(1) } }
36-46: Replace placeholder flag with a meaningful endpoint flag aligned with defaults.A generic “toggle” flag isn’t actionable. Given the test harness context, an endpoint flag is more useful and matches the repo’s default port 9891.
Apply:
func init() { @@ - // Cobra also supports local flags, which will only run - // when this action is called directly. - rootCmd.Flags().BoolP("toggle", "t", false, "Help message for toggle") + // Common endpoint for TinyKVPP gRPC server + rootCmd.PersistentFlags().StringP("endpoint", "e", "127.0.0.1:9891", "TinyKVPP gRPC endpoint (host:port)") }tests/go/kvtest/main.go (1)
1-5: Replace placeholder copyright.Update “NAME HERE ” with real project metadata.
Dockerfile (1)
9-16: Trim image size and harden apt usageConsider adding --no-install-recommends and noninteractive settings to reduce image size and avoid tzdata prompts in some bases.
Apply:
-RUN apt-get update && \ - apt-get -y install \ +ARG DEBIAN_FRONTEND=noninteractive +RUN apt-get update && \ + apt-get -y install --no-install-recommends \ cmake \ ninja-build \ python3 \ python3-pip \ python3-virtualenv && \ apt-get clean && \ rm -rf /var/lib/apt/lists/* /var/cache/apt/archives/*infra/assets/tkvpp_config_standalone.json (1)
28-36: Optional: align schema with config fieldsThe config carries "mode": "standalone" under database, but the JSON schema in src/config.cpp doesn’t define database.mode. Consider adding it (e.g., enum ["standalone","raft"]) to catch typos early.
src/config.cpp (2)
348-394: Wrong error message for missing peersThe else branch throws an error about "id" when "peers" is missing. Fix the message.
Apply:
- throw std::runtime_error("\"id\" is not specified in the config"); + throw std::runtime_error("\"peers\" is not specified in the config");
107-115: Tighten peers validation (host:port format, disallow 0.0.0.0)Currently peers are plain strings with no constraints. Consider a pattern like "host:port" and rejecting 0.0.0.0 via pattern or custom validation to prevent misconfiguration.
Example schema tweak:
"peers": { "type": "array", - "description": "Array of IPv4 addresses of peers", - "items": { "type": "string" } + "description": "Peer endpoints as host:port; do not use 0.0.0.0", + "items": { + "type": "string", + "pattern": "^(?!0\\.0\\.0\\.0:)[^:\\s]+:[0-9]{2,5}$" + } }infra/docker-compose.standalone.yaml (1)
5-7: Unconfined seccomp reduces container isolationUnless you rely on syscalls blocked by the default profile, keep default seccomp. If needed, provide a minimal custom profile instead of unconfined.
Would you like a minimal seccomp profile template that permits only the required syscalls?
tests/go/kvtest/pkg/core/config.go (2)
23-30: Nit: comment wording"AdapterConfig specified..." → "AdapterConfig specifies...".
Apply:
-// AdapterConfig specified which KV store adapter to use +// AdapterConfig specifies which KV store adapter to use
79-87: Consider ramp-up and weights defaultsProviding non-zero RampUpTime and operation Weights helps produce smoother load profiles and reproducible mixes.
Apply:
Load: LoadConfig{ Enabled: true, Algorithm: "constant", StartUsers: 1, TargetUsers: 10, - Duration: 60 * time.Second, - ThinkTime: 100 * time.Microsecond, + Duration: 60 * time.Second, + RampUpTime: 5 * time.Second, + ThinkTime: 100 * time.Microsecond, + Weights: map[string]int{"read": 70, "write": 30}, },tests/go/kvtest/proto/tinykvpp/v1/tinykvpp_service.proto (2)
17-20: Prefer gRPC status for errors; if keeping fields, rename for clarityReturning both success and error string is redundant and non-idiomatic in gRPC-Go. Prefer returning only the response payloads and convey failures via gRPC status codes. If you want to keep fields for this harness, consider renaming error -> message to avoid implying transport-level failure.
Example proto tweak (optional):
-message PutResponse { - bool success = 1; - string error = 2; -} +message PutResponse { + bool success = 1; // true if write succeeded + string message = 2; // optional context; not a transport error +}
26-29: Consider bytes for values to allow binary payloadsIf keys/values may contain arbitrary bytes, strings can corrupt data. Using bytes makes the API future-proof even for non-UTF8 data.
-message GetResponse { - bool found = 1; - string value = 2; -} +message GetResponse { + bool found = 1; + bytes value = 2; +}(If you do this, update PutRequest.value to bytes too, and adjust the adapter accordingly.)
tests/go/kvtest/proto/raft/v1/raft_service.proto (2)
24-28: Field numbering gap in LogEntry; either renumber now or reserve 3New file: safest is to use contiguous numbering. If 3 is intentionally removed, reserve it explicitly to avoid future collisions.
Option A — renumber now (preferred if no wire compatibility constraints yet):
message LogEntry { uint32 term = 1; uint32 index = 2; - bytes payload = 4; + bytes payload = 3; }Option B — keep as-is but reserve 3:
message LogEntry { uint32 term = 1; uint32 index = 2; + reserved 3; bytes payload = 4; }
61-69: Replicate RPC: acceptable as a test hookGiven this is test harness-only, the shape is fine. Consider bytes for payloads if you foresee binary.
tests/go/kvtest/pkg/core/context.go (2)
7-11: Private ctx field is unused; either expose it or remove itRight now ctx is dead weight. Expose it via a getter/setter or drop it to keep TestContext minimal.
Option A — provide accessors:
type TestContext struct { KVStore KVStoreInterface - ctx context.Context + ctx context.Context } +// Context returns the base context used by tests. +func (t TestContext) Context() context.Context { return t.ctx } + +// WithContext replaces the base context. +func (t *TestContext) WithContext(ctx context.Context) { t.ctx = ctx }Option B — remove ctx entirely if callers always pass their own contexts.
13-18: Constructor returns by value; consider pointer if the context will mutateIf you plan to mutate internal state (e.g., swap ctx), returning a pointer avoids copies. If it stays immutable, returning by value is fine.
-func NewTestContext(adapter KVStoreInterface) TestContext { - return TestContext{ +func NewTestContext(adapter KVStoreInterface) *TestContext { + return &TestContext{ KVStore: adapter, ctx: context.Background(), } }tests/go/kvtest/pkg/core/interface.go (2)
10-22: Interface shape is clear; consider adding Delete or dropping ErrDeleteFailedYou define ErrDeleteFailed but the interface has no Delete method. Either add Delete to the interface or remove the error to avoid dead code.
Option A — add Delete:
type KVStoreInterface interface { // Connection management Connect(config Config) error Close() error // CRUD operations Get(ctx context.Context, key []byte) ([]byte, error) Put(ctx context.Context, key, value []byte) error + Delete(ctx context.Context, key []byte) error // Testing utilities HealthCheck(ctx context.Context) error Name() string }(Adapters/tests will need minor updates.)
Option B — remove ErrDeleteFailed if delete is out of scope for now.
34-39: Predefined errors: consider simpler sentinelsUsing context.DeadlineExceeded/Canceled as inner causes may confuse callers. Consider basic sentinels (errors.New) and wrap transport errors at call sites.
If you agree, I can generate a follow-up patch replacing these with simple sentinels and updating adapter checks with errors.Is.
tests/go/kvtest/pkg/adapters/tinykvpp.go (1)
15-21: Config has MaxRetries but no retry logic; either implement or dropIf you want basic resilience, add a bounded, jittered retry on Unavailable/DeadlineExceeded for Get/Put. Otherwise, remove MaxRetries to avoid confusion.
I can add a simple retry helper with exponential backoff guarded by context deadlines; say the word and I’ll draft it.

158-159: LGTM: fmt placeholder fixedSwapping %s for {} in the "Unable to open config file" error message correctly uses fmt formatting.
63-84: Verify C++ mapping formaximumLevelsbefore updating schemaI searched for a corresponding C++ field or config‐struct for “maximumLevels” (e.g.
LSMTreeConfig, anyfrom_json/to_jsonoverloads, or direct references to"maximumLevels"insrc/) but didn’t find one. Before adding the new property to the JSON schema, please:• Confirm that your LSM configuration struct (whether named
LSMConfig,LSMTreeConfig, etc.) actually declares amaximumLevelsmember (and thatfrom_json/loader code reads it).
• If it doesn’t exist yet, add the field and mapping in the appropriate header/loader.
• Once the C++ side supports it, extend the schema insrc/config.cppas follows:"properties": { "flushThreshold": { "type": "integer", "description": "The threshold of bytes at which the memtable should be flushed", "minimum": 1 }, + "maximumLevels": { + "type": "integer", + "description": "Maximum number of LSM levels", + "minimum": 1 + }, "levelZeroCompaction": { "$ref": "#/$defs/compaction" },This ensures the schema’s
requiredlist aligns with both your examples (infra/assets/...) and the actual C++ config handling.infra/docker-compose.standalone.yaml (2)
4-4: Image name vs Dockerfile build targetCompose references image: tinykvpp-clang:latest, while Dockerfile defaults to TARGET=gcc. Ensure your CI publishes a clang-based image at this name or add a build section to compose with appropriate ARGs.
Suggested compose tweak if building locally:
- tkvpp-node-standalone: - image: tinykvpp-clang:latest + tkvpp-node-standalone: + build: + context: ../.. # adjust to repo root containing Dockerfile + dockerfile: Dockerfile + args: + TARGET: clang + image: tinykvpp-clang:latest

Avoid duplicate entrypoints; keep only one main.
You now have two mains:
- tests/go/kvtest/main.go (calls cmd.Execute())
- tests/go/kvtest/cmd/kvtest/main.go (this file)
Pick a single layout:
- Option A (simplest): Keep tests/go/kvtest/main.go and delete tests/go/kvtest/cmd/kvtest/main.go.
- Option B (conventional multi-command): Move root.go under tests/go/kvtest/cmd/kvtest (package cmd), keep this main to call cmd.Execute(), and remove tests/go/kvtest/main.go.
Having both will confuse consumers and CI; with the current syntax error, the module cannot be built.
Run the following to enumerate all main packages under kvtest and confirm you have only one after the change:

Remove the duplicate main entrypoint
The verification script still finds two package main declarations under tests/go/kvtest:
- tests/go/kvtest/main.go
- tests/go/kvtest/cmd/kvtest/main.go
You must choose one layout and delete the other to ensure there’s only a single executable entrypoint:

• Keeptests/go/kvtest/cmd/kvtest/main.goto callcmd.Execute().

Fix compile error: empty import block is invalid.
import () is a syntax error in Go (“expected import path, found ')'”). This file will not compile as-is.
If you intend to keep this entrypoint, wire it to Cobra and remove the empty import:

Import path for pb must match proto go_package
Once you fix go_package in tinykvpp_service.proto, ensure this import matches it. See the proto review for two consistent options.

Add go_package for Go codegen; without it, imports will be fragile
The Go plugin strongly recommends specifying go_package. Add one that matches where you’ll import the generated code.
syntax = "proto3";
package raft.v1;
+option go_package = "github.com/lnikon/tinykvpp/tests/go/kvtest/proto/raft/v1";If you plan to place generated files under a different path, tell me the final location so I can align imports across the test harness.
Add a go_package option for reliable Go imports
To ensure generated Go code imports consistently (and avoid fragile relative paths), specify the go_package option in your .proto file. For example, if your module path in go.mod is github.com/lnikon/tinykvpp and you’re placing the generated files under tests/go/kvtest/proto/raft/v1, add:
File: tests/go/kvtest/proto/raft/v1/raft_service.proto (lines 1–5)
syntax = "proto3";
package raft.v1;
+option go_package = "github.com/lnikon/tinykvpp/tests/go/kvtest/proto/raft/v1";
service RaftService {• Verify that this import path matches exactly where you’ll generate the Go code.
• If you intend to generate into a different location, please share the final import path so we can align the go_package value with your test harness.

🧩 Analysis chain
ID types are inconsistent; unify to a single type across requests/responses
leader_id is string here while sender_id is uint32; responses use responder_id uint32. Pick one type (string or uint32/uint64) and use it consistently across all messages. For Raft, numeric IDs (uint64) are common.
Example (numeric IDs):
message AppendEntriesRequest {
uint32 term = 1;
- string leader_id = 2;
+ uint32 leader_id = 2;
uint32 prev_log_index = 3;
uint32 prev_log_term = 4;
repeated LogEntry entries = 5;
uint32 leader_commit = 6;
uint32 sender_id = 7;
}Apply the same choice to RequestVoteRequest and all responses.
Do you prefer uint64 for term/index/node IDs to avoid future overflow in long-running tests?

Unify all node ID fields to a single numeric type
Across the four Raft RPC messages, the ID fields use mixed types— leader_id is a string, while sender_id, candidate_id, and both responder_id fields are uint32. We should pick one numeric type and apply it consistently. In Raft implementations it’s common to use 64-bit unsigned integers for node IDs (to avoid overflow in long-running clusters and tests).
Please update:
AppendEntriesRequest:- change
string leader_id = 2;→uint64 leader_id = 2; - change
uint32 sender_id = 7;→uint64 sender_id = 7;
- change
RequestVoteRequest:- change
uint32 candidate_id = 2;→uint64 candidate_id = 2;
- change
AppendEntriesResponse:- change
uint32 responder_id = 4;→uint64 responder_id = 4;
- change
RequestVoteResponse:- change
uint32 responder_id = 3;→uint64 responder_id = 3;
- change
Example diff for AppendEntriesRequest:
message AppendEntriesRequest {
- uint32 term = 1;
- string leader_id = 2;
+ uint32 term = 1; // term/index fields left as uint32 for now
+ uint64 leader_id = 2; // unify node IDs to uint64
uint32 prev_log_index = 3;
uint32 prev_log_term = 4;
repeated LogEntry entries = 5;
uint32 leader_commit = 6;
- uint32 sender_id = 7;
+ uint64 sender_id = 7; // unified to uint64
}Question: should we also bump term, prev_log_index, prev_log_term, and leader_commit from uint32 to uint64 now to fully future-proof against very large log sizes and term numbers?

vote_granted should be a bool, not uint32
This is a correctness bug; consumers will expect a boolean.

RequestVoteResponse.message defines vote_granted as uint32 but it should be a
bool; change the field type to "bool vote_granted = 2;" (keep the field number 2
unchanged), then regenerate all protobuf artifacts (Go, any other language
bindings) and update any tests or call sites that set or read vote_granted to
use boolean values instead of integers to ensure consumers see the correct type.

🛠️ Refactor suggestion
Align go_package with actual import path to avoid Go import mismatches
Adapter imports pb from tests/go/kvtest/proto/tinykvpp/v1, but go_package points to github.com/lnikon/tinykvpp/protos/tinykvpp/v1. This will generate code under a different module path than the one you import, leading to build errors.
Apply one of the following diffs (pick one and keep things consistent across repo):
Option A — keep current adapter import path:
-option go_package = "github.com/lnikon/tinykvpp/protos/tinykvpp/v1";
+option go_package = "github.com/lnikon/tinykvpp/tests/go/kvtest/proto/tinykvpp/v1";Option B — move generated code to match go_package and update adapter import:
- pb "github.com/lnikon/tinykvpp/tests/go/kvtest/proto/tinykvpp/v1"
+ pb "github.com/lnikon/tinykvpp/protos/tinykvpp/v1"📝 Committable suggestion

Reserve field numbers explicitly and sketch batch extensibility
You skipped field 4 with a comment, but did not formally reserve it. Explicit reservations prevent accidental reuse and wire incompatibilities.
message DatabaseOperation {
enum Type {
TYPE_UNSPECIFIED = 0;
TYPE_PUT = 1;
TYPE_DELETE = 2;
TYPE_BATCH = 3;
}
Type type = 1;
string key = 2;
string value = 3;
- // Reserve 4 for Batch operations
+ // Reserved for future batch payload
+ reserved 4;
uint64 request_id = 5;
}Optional: If batch is imminent, define it now to avoid another wire change:
message BatchOperation {
repeated DatabaseOperation ops = 1;
}Would you like me to propagate the corresponding Go changes (adapter + tests) if you switch to bytes and/or add BatchOperation?
Add explicit reserved 4; and sketch BatchOperation for forward‐compatibility
To avoid accidental reuse of tag 4 and ensure wire compatibility, please formally reserve it rather than just commenting it out:
• File: tests/go/kvtest/proto/tinykvpp/v1/tinykvpp_service.proto
• Location: inside message DatabaseOperation, between fields 3 and 5
Proposed diff:
message DatabaseOperation {
enum Type {
TYPE_UNSPECIFIED = 0;
TYPE_PUT = 1;
TYPE_DELETE = 2;
TYPE_BATCH = 3;
}
Type type = 1;
string key = 2;
string value = 3;
- // Reserve 4 for Batch operations
+ // Reserved for future batch payload
+ reserved 4;
uint64 request_id = 5;
}Optional enhancement: if you intend to implement batching soon, add a BatchOperation now to avoid another wire‐breaking change:
message BatchOperation {
repeated DatabaseOperation ops = 1;

In tests/go/kvtest/proto/tinykvpp/v1/tinykvpp_service.proto around lines 31-45,
the comment "Reserve 4 for Batch operations" should be implemented by formally
reserving tag 4 inside message DatabaseOperation to prevent reuse (add the
reserved 4; declaration between fields 3 and 5), and optionally add a new
message BatchOperation (containing a repeated DatabaseOperation field) after
DatabaseOperation so future batching uses a defined type instead of reclaiming
tag 4; ensure the .proto compiles and update any generated stubs if present.
