If no, the comment is doing real work. + +The examples below are illustrative, not quoted from a real file, so they stay true when the code changes. The first is a doc summary for an item that is not a getter: it states the item's role and the option that was turned down. The second states a duplicated-state rule, and the third explains a safety-critical guard. + +```rust +/// Keeps each partition within its topic's `retention.ms`, by deleting each batch whose +/// newest record is older than that. +/// +/// A failed run leaves the expired batches in place until the next run.

A comment reading `// increment the counter` above `count += 1` conveys strictly less than the code while any genuinely useful fact (thread safety, units, an invariant) goes unmentioned. `// loop through and output` above a `for` loop is the control-flow variant: it narrates the loop line and ignores whatever is actually surprising in the body. +- **Never comment to rescue unclear code.** Rename the variable, extract the function, split the conditional. A comment explaining a bad name is two problems. +- **Never leave commented-out code.** Delete it; version control remembers. +- **Never narrate history.** No "changed this because…", no "previously we…", no ticket numbers as scar tissue. Comments describe the end state; write for a future reader who has no context about what changed. The *external* defect a workaround exists for is end state and belongs (see Markers below) — a live constraint, not a record of a past edit. +- **Never section-label straight-line code.** `// Step 1`, `// Options` are a sign the block wants to be a function. +- **Never describe another file.** See "Remote Comments" below. +- **Never rewrite a comment that already passes these rules.** In a comment pass, change a comment only when it breaks a rule. A different wording that also passes is churn, and a reviewer has to check it again. When a comment does need a rewrite, keep every true fact from the old comment, and keep the most important one first. + +## Function-Header Scope vs. Inline Detail + +A function's leading comment (its doc comment or header comment) describes the function's **contract** — what it does, why it exists, and any non-obvious constraint that governs the whole function. It never narrates the body. + +AI-written code is especially prone to the opposite failure: a paragraph at the top that walks the reader through the implementation step by step — "first parses the header, then validates it, then dispatches to the handler" — duplicating in prose what the code already shows in order. That paragraph goes stale the moment a step is reordered, added, or removed, and it teaches the reader nothing three lines down wouldn't. + +If a specific line or block has a genuinely non-obvious detail — the actual subject of "When To Write One" above — put that comment **directly above the line or block it explains**, not folded into the function's header. The header stays about the function as a whole; a local comment stays local. + +```rust +/// Parses a frame header and dispatches it to the matching handler. +/// +/// Returns `Err` if the frame's declared length exceeds `MAX_FRAME_SIZE` — callers +/// rely on this to bound how much they buffer before this call returns. +fn dispatch(frame: &[u8]) -> Result { + let header = parse_header(frame)?; + + // The wire format allows a zero-length payload only for a heartbeat; every + // other message type must carry at least one field. + if header.payload_len == 0 && header.kind != FrameKind::Heartbeat { + return Err(DispatchError::EmptyPayload); + } + + route(header, &frame[HEADER_LEN..]) +} +``` + +The doc comment above `dispatch` states its contract — what triggers `Err` — and says nothing about parsing, then validating, then dispatching; the code already shows that. The one implementation detail worth a comment (why a zero-length payload is sometimes valid) sits directly above the `if` it explains, not folded into the function's opening paragraph. + +## Remote Comments + +A *remote comment* describes the contents or behaviour of some other file that this code is not coupled to. It is the worst kind of stale comment, because nobody editing that other file thinks to look here. Illustrative example (not from a real file): + +```rust +// The following variants are handled by this dispatcher: +// (1) Request::Create +// (2) Request::Update +// (3) Request::Delete +match request { + Request::Create(r) => handle_create(r), + Request::Update(r) => handle_update(r), + Request::Delete(r) => handle_delete(r), +} +``` + +A hand-maintained index of variants declared elsewhere, sitting above the `match` that already enumerates them in its own arms. It is redundant the day it is written and silently wrong the day a fourth variant is added. Delete it — the `match` is the authoritative list. + +The distinction is **coupling**, not proximity. The test: **would a change on the other side reach this code?** If yes, write the comment — the coupling is real and you are documenting *this* code's constraint. If no, it is remote: the other side changes, nothing here notices, and the prose rots unobserved. + +**Allowed** — a real dependency this code has on the other side: + +- An ordering requirement, a value that must be kept in sync, or an obligation a caller must honour. +- Local code that looks unusual, redundant, or plainly wrong and exists only to meet a remote API's requirements — a value that must be set before some function is called because the callee reads it lazily; a resource kept alive because the callee stores a reference to it rather than copying it. Without a note these read as mistakes and get "cleaned up." +- Why this code is shaped as it is to satisfy another component's published contract — e.g. `// the peer expects the length prefix in network byte order, so we call to_be_bytes() before writing it`. Such a comment can drift, but it drifts *with the caller*: break that contract and this code stops working, so whoever changes it is already editing here. + +**Not allowed** — restating another file's or function's *internals*, inventorying its contents or steps, or naming a file just to point at it. + +The line between them is the **contract**, never the other side's internals. "Read before the connection is established" and "must be called before `init()` returns" are contracts; "sets the `ready` flag under a lock" is an internal, and it rots unobserved because nothing here depends on it. The same holds in reverse — do not name a function's call sites in its own comments or doc comment; describe behaviour and contract instead. Naming a caller is acceptable only when the function is tightly coupled to exactly one site. + +Prefer expressing a real coupling in something that *breaks* when it drifts — a `const` assertion, a `debug_assert!`, a lint, an intra-doc link, a test — and drop the comment. A comment is the fallback for coupling the language cannot express. + +## Doc Comments + +A doc comment (a language's own doc-comment convention — Rust's `///`, a Python docstring, a Markdown page's lead paragraph) is orientation for the next reader, not reference documentation: + +- One-line summary for anything whose name is not self-evident. Skip it entirely when the signature or heading already says everything. +- Longer form only when there is a real invariant, unit, or failure mode to state — see "Function-Header Scope vs. Inline Detail" above for where the line falls. +- **No boilerplate that restates the signature with no new information.** "Returns a `Result`" adds nothing the signature doesn't already show. Rust's `# Errors` and `# Panics` sections are the right place for the load-bearing facts a signature can't carry — *which* condition produces *which* error variant, or under what non-obvious condition the function panics — but only when they say that, not just that errors or panics are possible (Rust API Guidelines [C-FAILURE](https://rust-lang.github.io/api-guidelines/documentation.html#c-failure)). + +## Rust + +These rules add to the rules above for Rust code. They come from the [rustdoc book](https://doc.rust-lang.org/rustdoc/), [RFC 1574](https://rust-lang.github.io/rfcs/1574-more-api-documentation-conventions.html), the [Rust Style Guide](https://doc.rust-lang.org/style-guide/), and the [Rust API Guidelines](https://rust-lang.github.io/api-guidelines/documentation.html). + +- **Use `///` for an item's header, and `//!` for a crate or a module.** rustdoc and rust-analyzer show a `///` comment, also on a private item, and they do not show a `//` comment. Use `//` inside a body, and for a note about an attribute. Put a doc comment before the item's attributes. +- **Write the summary as the first sentence, and make it say what a caller can rely on.** rustdoc shows the first paragraph on module pages and in search results. The summary still has to pass the reconstruct-from-code test in "When To Write One". A function's summary starts with a verb in the third person. "Returns" or "Opens" fits a getter or a constructor. For a background task, a type, or a constant, state the item's role, because a summary of the body restates the code: "Keeps each partition within its retention limit" states a role, and "Deletes each expired batch" restates a loop. +- **Give a crate or a module a `//!` summary when its name does not state its purpose.** State the purpose. Do not list the items, because rustdoc lists them. +- **Link a named item with an intra-doc link,** such as ``[`Vec::push`]``. `just doc` fails CI when someone renames or removes the target of a link in a library or a binary. A public item must not link to a private item (`private_intra_doc_links`), so name a private item in plain backticks there. rustdoc resolves links only in doc comments. +- **Write an example as a doctest.** `just test-doc` compiles and runs it, as a separate crate, so it can call only public items. Add an example only when the signature does not show how to call the item. Use `no_run`, not `ignore`, so that the example still compiles, and use `?`, not `unwrap()` ([C-EXAMPLE](https://rust-lang.github.io/api-guidelines/documentation.html#c-example), [C-QUESTION-MARK](https://rust-lang.github.io/api-guidelines/documentation.html#c-question-mark)). +- **Do not comment a rule that a lint enforces.** CI runs clippy with `-D warnings`, so `clippy::await_holding_lock` already fails a build that holds a `std::sync` lock across an `.await`. A comment that says so adds nothing. +- **Write a clap doc comment for the operator, on one line.** clap shows a field's doc comment as its `--help` text. +- **Put an identifier in backticks.** rustdoc renders Markdown, so it shows the identifier as code, and an underscore in the name does not become emphasis. + +## Form + +- Use [ASD-STE100 Simplified Technical English](https://www.asd-ste100.org/): one idea per sentence, active voice, present tense, the same word for the same thing, no idioms. +- Complete sentences, capitalised, in the language's native comment syntax. A fragment like `// hack` never survives contact with a future reader. +- Explain **why**, not **what**. The code already says what. +- Put it where the confusion is — at the call site if that is where the surprise lands. +- Wrap to the file's prevailing width. Keep it shorter than the code it explains; a paragraph over a two-line function is a design smell. +- **One point per comment.** A comment above a condition or a block states the rule that the code enforces first, and the reason after it. When a block has several reasons, write one comment for each, above the line that it explains. One paragraph that covers all of them makes the reader work out which reason goes with which line. + +## Say It Directly + +Form is not enough on its own. The failure below survives every rule above, and it is the one a review catches again and again: prose that circles a fact instead of stating it. + +**Name the actor, and say when the actor is us.** An agentless sentence hides who does the thing, and the reader then cannot tell whether the behaviour is ours to change. The rule applies when the actor is unclear. When the actor is the code right below the comment, a passive sentence is clear, and it does not need a "we". + +- No: `// a preloaded library loads before the sanitizer runtime` +- Yes: `// we preload the syslog shim, so it loads before the sanitizer runtime` + +**Make the mechanism the subject.** A sentence that opens with "That report", "This behaviour", or "It" sends the reader back to the previous sentence to find out what acts, and a relative clause that defines a name in passing ("quiet, which marks a failure the caller expects") hides the definition where nobody looks for one. Name the mechanism, say what it does, and attach the reason with "because." Write subject, verb, object. A sentence that opens with the object, or with a long clause before the verb, makes the reader hold the whole sentence in mind before they know what acts. + +- No: `// That flag ignores quiet, which marks a failure the caller expects; nobody expects the command to be absent.` +- Yes: `// quiet does not ignore a missing command, because that is a critical failure.` + +**State the fact. Do not invent a condition that the code has already decided.** When the code sets a value, say what the value does. A conditional word implies a choice that the reader does not have. + +- No: `// The retry loop stops unless this flag allows another attempt.` The flag is set, and it does allow another attempt, so "unless" describes nothing. +- Yes: `// The retry loop stops after N attempts, and this flag raises that limit.` + +**Name the thing.** A category noun makes the reader search for what is meant. + +- No: "a read yields a fixed-size value, so keep the buffer that size" +- Yes: "a single `recv` call on this socket yields exactly one frame" + +**Use the name that the code uses.** A term that only the prose uses spreads to other comments, and it leaves open what it covers. If prose needs a new term, define it once, where the thing is defined. + +- No: `// the coordinator evicts each stale member`. The reader cannot tell whether a member that left the group is stale, or whether an eviction starts a rebalance. +- Yes: `// the coordinator removes each member whose session timeout has expired` + +**Name the option that was turned down, and make the reason lead to the choice.** A comment that explains a choice states the alternative, because the alternative is half of the decision. Check that the reason supports the choice it sits next to. "A failed run only delays deletion" shows that one failure is harmless. It does not show why the task keeps running. This rule applies only to a choice that needs a comment by the test in "When To Write One". A choice that a reader would not question needs no comment, and so it needs no alternative. + +- No: `// a failed run only delays deletion, so this task keeps running after each error` +- Yes: `// this task keeps running after every error instead of stopping, because a stopped task would never delete another batch` + +**Do not list examples to make a point.** A list of examples names things that can change without notice. When one of them changes, the comment is wrong, and the list taught the reader nothing, because the code depends on none of the named items. State the point with a category noun. + +- No: `// this assumes a POSIX shell with bash, zsh, or dash semantics.` +- Yes: `// this assumes POSIX shell semantics.` + +**Negate the verb, never the noun.** "No X" and "without X" hide the negation inside a noun phrase, and the reader has to rebuild the sentence to find out what does not happen. + +- No: `// The response contains no field that identifies the caller.` +- Yes: `// The response does not identify the caller.` + +**Say what the code does, not what it does not do.** A negative sentence leaves the reader to work out the positive case, which is the one the code implements. + +- No: `// This check does not run for a request that only touches cached fields.` +- Yes: `// This check runs only for a request that touches uncached fields.` + +**Use plain words.** A metaphor makes the reader translate before they can check the claim. If the codebase has already adopted a metaphor as a domain term (a "queue," a "pool"), reuse it consistently; don't introduce a new one for effect. + +- No: `// The retry landed cleanly, giving the request a two-step shape.` +- Yes: `// The retry succeeded. The request took two attempts.` + +**Give agency only to a thing that acts.** A process, a check, or a function does something. A file, a flag, or a value is acted on, and a sentence that has it "want," "decide," or "know" hides the real actor. An abstract noun is not an actor either: a decision, a requirement, a result, or a failure does not need, expect, or know anything. A need belongs to the process or the person that has it, so write that actor as the subject. + +- No: `// The flag knows the queue is unavailable.` +- Yes: `// The dispatcher reads the flag and skips the queue.` + +**State a requirement, not an observation, and leave a breadcrumb.** A sentence about how the world is today rots the moment the world changes, and it rots silently, because nothing fails when it stops being true. A sentence about what this code requires stays true whatever the world does. + +- Observation (rots silently): `// our process starts before the sidecar does.` +- Requirement (stays true): `// this code does not require the sidecar to be ready before startup.` + +A requirement alone, though, strands the next reader: it says what was decided and gives them no way to reach why. Name the tracked issue if one exists — it holds the evidence that would otherwise rot in the comment (which conditions, why the cost was acceptable), and a reader who needs that history knows exactly where to find it. The comment states what is permanently true; the breadcrumb leads to what was true at the time. + +The breadcrumb names an issue, never a pull request or a commit. A pull request or a commit records a change that is already done, and that is history (see "Never narrate history"). + +**Open with the plainest statement of what the code is.** The first sentence is a label, not a summary of everything the code does. + +- No: `// The set of options that every process this workspace builds starts with.` +- Yes: `// The default startup options for this workspace's processes.` + +The test: read the sentence aloud. Rewrite it as subject, verb, object when it takes a clause to reach its subject, when it gives agency to a thing that does not act, or when it uses "unless," "would," or "can" for something the code already settled. + +## Markers + +Unfinished work belongs in the project's issue tracker (GitHub issues), not in the source.

Pull +requests don't edit it; describe user- and operator-visible changes in the +pull request description instead, which becomes the body of the commit on +`main`. + +The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), +and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). + +## [Unreleased] + +### Changed + +- The S3 and in-memory (DynoStore) storage engine stores each consumer + group id as exactly one segment of its object key. Keys for other ids + are unchanged. These keys move, and data under the old keys is not + migrated: + - an id containing `/`: its committed offsets and group state; + - the empty id `""`, which consumers using `assign()` commit under: its + committed offsets and group state; + - `.` and `..`: the group state only. + An affected group's consumers find no committed offset and start from + `auto.offset.reset`. With the Java client default, `latest`, they skip + records they had not yet consumed. Old data stays visible in ListGroups: + old `""` data lists as a group named `offsets`, and old `a/b` data as a + group named `a`. Deleting that group removes it. +- Upgrade every broker sharing a bucket before using these ids. An old and + a new broker read and write different keys for them, so members connected + to different brokers form two separate groups. A rollback returns these + groups to the offsets they had before the upgrade. +- The broker's default `--kafka-listener-url` is now `tcp://[::]:9092`, which accepts both IPv6 and IPv4 clients. On a host without IPv6 support, the broker falls back to `0.0.0.0` on the same port and logs a warning; set `LISTENER_URL=tcp://0.0.0.0:9092` to listen on IPv4 only. +- The default advertised listener, and the default broker URL of the `nisshi` client subcommands, are now `127.0.0.1:9092` instead of `localhost:9092`. A client whose resolver returns `::1` for `localhost` first no longer gets connection refused. +- A consumer whose position is below a partition's log start offset now applies `auto.offset.reset`, as with Apache Kafka: Fetch answers `OFFSET_OUT_OF_RANGE` straight away, where it used to return the earliest surviving record. This shows on slatedb after retention, DeleteRecords, or compaction by an earlier version: `v0.7.0-pre.1` and `v0.7.0-pre.2` moved the log start to the first surviving batch on compaction, and their Fetch had no bounds check, so a consumer behind that log start read the first surviving batch. After the upgrade that log start stays where it is, so on a compacted slatedb topic a group that is offline or lagging resets for the first time. With the default `latest`, the consumer skips the retained backlog, which on a topic that rewrites a few keys often (such as a config topic) can be nearly all of it; with `none`, the application gets an exception. Before you upgrade, compare each group's committed offsets with ListOffsets `earliest` on slatedb topics, compacted ones in particular, and reset lagging groups to `earliest`. Run consumers of compacted slatedb topics with `auto.offset.reset=earliest` across the upgrade, because compaction by the old version keeps raising the log start between that check and the upgrade itself. The log start is the batch the old version would have served, so a reset to it loses nothing. These answers are counted in `nisshi_fetch_offset_out_of_bounds` with `bound` set to `below_log_start`, which after the upgrade also shows consumers that the group comparison misses, such as those that use `assign` with offsets stored outside Kafka. +- Fetch answers straight away, instead of after `max_wait`, when any partition is `OFFSET_OUT_OF_RANGE` or every partition has an error. A consumer assigned only to a deleted topic now fetches at its error backoff rather than once per `max_wait`. +- A listener with SASL configured closes a connection that sends a frame larger than 512KiB before the client authenticates, matching the Apache Kafka default for `sasl.server.max.receive.size`. The same limit applies while a client re-authenticates. The broker logs this rejection as `PreAuthenticationFrameTooBig`, and counts it in `nisshi_frames_rejected`. +- The proxy forwards a batched Produce (`tansu.batch=true`) with the strictest `acks` among the batched requests, and at least `acks=1`, so the origin answers it. Upgrade proxies before brokers: an older proxy forwards batches with `acks=0` and waits for a response that an upgraded broker no longer sends. +- Known limitation: the proxy still waits for a response to an `acks=0` Produce that it passes through unbatched. Against an upgraded broker, that request stalls until the broker's connection idle timeout closes the upstream connection. +- The broker stops at startup when its storage URL has a query option that the storage engine does not read, such as a misspelt option or `vacuum_into` on a `postgres://` URL. The error names the option and the engine. Previously the broker ignored the option. +- The broker stops at startup when `maintenance_interval` or `transaction_maintenance_interval` has an invalid value: unparsable, zero, longer than 365 days, or a bare number without a unit. Previously the broker ignored an invalid value and used the default interval. Give a bare number its unit, for example `600s` or `10m` instead of `600`. Compound values such as `1h30m` and `5min` still work. +- A `parquet`, `iceberg` or `delta` broker without `--schema-registry` stops at startup with an error that names the missing option, instead of panicking. `--schema-registry` is accepted before or after the subcommand. +- When the broker closes the connection of a client that sends a request other than ApiVersions, SaslHandshake or SaslAuthenticate before it authenticates, it logs an ERROR line that names the client's address. +- `nisshi proxy` and the CLI tools bound every wait on the broker they connect to ([#882](https://github.com/nisshi-io/nisshi/issues/882)): + - A request fails with `Timeout` when the broker does not answer within 30s. A request that asks the broker to wait (Fetch, Produce, JoinGroup, and the topic and partition admin requests) gets that wait plus 5s instead, when that is longer, with the wait capped at 5 minutes. `nisshi proxy` then closes the client's connection, and the client retries. + - A request fails with `Pool(Timeout(Wait))` after 30s without a free connection, and with `Pool(Timeout(Create))` when a new connection takes more than 30s to open. + - `nisshi proxy` opens up to 256 connections to its origin, instead of twice the number of CPUs. + - `nisshi_client::Builder` sets these with `request_timeout`, `max_request_wait`, `wait_timeout`, `connect_timeout`, `max_idle` and `max_size`. + - New metrics: `request_timeouts`, `pool_get_errors` (by `error`) and `pool_connections_discarded` (by `reason`). +- Logs write `[hidden]` in place of SASL auth bytes, SCRAM salted passwords, delegation token HMACs, stored SCRAM keys, and config values in `AlterConfigs` and `IncrementalAlterConfigs` requests, at every log level. Frames, record batches, record keys and values, and record header values are logged with the length of their bytes, not the bytes. SQL statements are logged without their parameters, and schema validation and lake conversion log the field and the kind of value, not the value. +- `nisshi_schema::Error`: `AvroToJson` and `InvalidValue` hold an Avro `SchemaKind`, and `JsonToAvro` and `UnsupportedSchemaRuntimeValue` hold the kind of JSON value, in place of the value. `JsonToAvroFieldNotFound` no longer has a `value` field. The new `AvroRecord` variant reports an Avro record that fails to read or write against its schema, without the `apache_avro` error, whose message holds the record's values. +- A broker on S3 or Google Cloud Storage exits at startup when it cannot list its cluster's prefix in the bucket, or when its AWS credential provider does not return a credential. The error names the storage URL and the cause. Previously the broker started and failed on its first request. +- InitProducerId follows Apache Kafka 3.9.1 on every storage engine when a producer + sends its current producer ID and epoch to bump its epoch after an error (KIP-360): + - Without a transactional ID, the producer gets a new producer ID, whatever it + sends. + - With a transactional ID that has no producer yet, the broker creates one. + - With a transactional ID that has a producer, the broker bumps the epoch only + when the request has that producer's ID and current epoch. Otherwise it + answers `PRODUCER_FENCED`. On PostgreSQL, this replaces `UNKNOWN_PRODUCER_ID` + for an unknown producer ID. + - A request that sets only one of producer ID and epoch to -1 gets + `INVALID_REQUEST`. + - A failed InitProducerId answers producer ID and epoch -1, and the broker logs + the request at info. +- Two differences from Apache Kafka remain. Kafka also accepts the previous epoch, + from a producer that retries a bump whose response it lost; the broker answers + `PRODUCER_FENCED`, and the producer must initialise again. Kafka answers + `INVALID_PRODUCER_EPOCH` instead of `PRODUCER_FENCED` to InitProducerId v3 and + older; the broker answers `PRODUCER_FENCED` at every version. +- Releases no longer include an `x86_64-apple-darwin` (Intel macOS) binary. Apple silicon (`aarch64-apple-darwin`) is the only macOS build. + +### Security + +- Decoding a produce batch is bounded. Previously a few KB of compressed + data could decompress into gigabytes, and a record carrying millions of + empty headers expanded 32x on decode. Now a batch is rejected with + `MESSAGE_TOO_LARGE` once its decompressed bytes, or its decoded records + and headers, pass a 100 MiB budget, or up front when its `record_count` + alone would. A producer can recover by splitting the batch (the Java + producer does this on its own for a batch of more than one record). +- Peak memory while decoding one batch is a small multiple of that budget + (roughly 2 to 3x), not 100 MiB exactly: + - an uncompressed record's headers are charged after they are allocated, + so the record that crosses the budget can add up to about 100 MiB more; + - a Snappy batch holds its decompressed block (up to 100 MiB) alongside + the records decoded from it; + - zstd's decoder window, up to 128 MiB, sits outside the budget. + The budget applies per batch; concurrent batches each have their own. + +### Fixed + +- On S3 and in-memory storage, a consumer group whose id contains `/` or is + empty no longer shares offsets or group state with another group. Group + `a/` no longer reads or overwrites the committed offsets of group `a`, and + deleting group `a` no longer deletes group `a/b`. Deleting a topic now also + removes the committed offsets that such groups hold for it. +- On S3 and in-memory storage, ListGroups returns each group's real id. For + an id with a reserved character it returned the encoded form (`a%23b` for + `a#b`, `%2E` for `.`), which DescribeGroups and DeleteGroups could not + find. +- On S3 and in-memory storage, DeleteGroups accepts the empty group id, as + the other storage engines do, instead of answering `INVALID_GROUP_ID`. +- A Snappy batch with a truncated xerial header is rejected with an error + instead of panicking the decoder. +- CreateTopics rejects a `replication_factor` of 0 or below -1 with `INVALID_REPLICATION_FACTOR` (38), as Apache Kafka does. -1 still selects the default (1). +- `DeleteGroups` refuses a group that still has members with + `NON_EMPTY_GROUP` (68), instead of deleting its state and committed + offsets out from under a live consumer. A member whose session has + expired does not count. The broker decides from stored group state, so a + member connected through another broker counts too, and a group whose + state the storage engine reports it cannot read is not deleted. The S3 + and in-memory storage engine still reports a group it cannot read as an + empty group, and SlateDB does the same for group state it cannot decode; + both are tracked separately. Only the broker that served the request + forgets its cached state for the deleted group; another broker that + cached the group can still write it back. A group named more than once + in one request is processed once. +- `DescribeGroups` and `DeleteGroups` on the PostgreSQL and libSQL + (including Turso) storage engines report a group that only ever + committed offsets, and never ran `JoinGroup`, as an empty group instead + of failing. +- SlateDB compaction skips a stored batch it cannot inflate, with a warning, + instead of abandoning the whole maintenance pass. +- DeleteTopics on the object-store backends (`s3://`, `gs://`, `memory://`) no longer deletes other topics' data or committed offsets when the deleted topic's name is empty or contains `/`. Such a topic is removed from metadata and the request answers `NONE`, but its data objects stay in the bucket, and so do its committed offsets when the name has an empty segment (`a/`, `/a`, `a//b`, or empty). The broker logs each kept location at `warn` with the topic id. Do not delete those objects by key prefix: for several of these names they share keys with a live topic of the plain name, and must stay while it exists. Creating a topic whose name collapses onto such kept objects (`a` after `a/` was deleted) finds them in place and its first produce fails; delete `a` and create it again. +- The broker no longer writes a Produce response for an `acks=0` request. A storage or validation failure on an `acks=0` Produce now closes the connection (matching Apache Kafka) instead of silently dropping the batch. +- ListOffsets by timestamp now answers offset -1 and timestamp -1 with error NONE when no record has a timestamp at or after the target, as Apache Kafka does. The broker answered offset 0 before. That made the Java consumer's `offsetsForTimes()` throw `IllegalArgumentException: Invalid negative timestamp`, and it sent a client that seeks to the returned offset back to the start of the partition. A partition answered with an error code now also carries offset -1 instead of 0. +- `nisshi proxy` and the CLI tools no longer reuse a connection to the broker + that the broker closed, that has bytes nobody read, that was idle for more + than 9 minutes, or whose last request failed, timed out or was cancelled. + Such a connection could fail the next request, or give it the response to + an earlier one ([#882](https://github.com/nisshi-io/nisshi/issues/882)). +- Fetch for a topic name that doesn't exist now answers `UNKNOWN_TOPIC_OR_PARTITION`. Before, `postgres://`, `sqlite://` and `slatedb://` brokers closed the connection, and `memory://` and `s3://` brokers waited out `max_wait` and then answered with no error. A fetch that names only unknown topics answers at once; one that also names an existing topic waits for that topic's data as usual. A fetch by topic id for an id that doesn't exist gets its requested id back instead of the null id, so a Java consumer on a deleted topic refreshes its metadata instead of fetching again. +- InitProducerId v0 to v2 works on every storage engine. These versions do not + carry a producer ID or epoch. libSQL and Turso panicked on them, and on a + KIP-360 epoch bump, ending the connection. The object store engines + (`memory://`, `s3://`, `gs://`) answered `UNKNOWN_SERVER_ERROR`, and so did + SlateDB without a transactional ID. +- On PostgreSQL, concurrent InitProducerId requests for one transactional ID + bump its epoch one at a time. Before, two of them could both succeed, and one + could fail with a storage error. +- Fetch checks the fetch offset before it reaches the storage engine, so a storage engine never receives an offset such as `i64::MAX`. Above the high watermark, Fetch answers `NONE` with no records on every engine. Apache Kafka answers `NONE` only up to the log end offset and `OFFSET_OUT_OF_RANGE` above it; Nisshi answers `NONE` because a broker on dynostore can read a high watermark that lags a write through another broker. A consumer whose position is past the end of the log therefore waits there instead of applying `auto.offset.reset`. Such a consumer shows in `nisshi_fetch_offset_out_of_bounds` with `bound` set to `above_high_watermark`, counted once per poll round of a Fetch, so the counter shows whether parked fetches exist rather than how many; a short burst on dynostore with several brokers is expected. +- SlateDB compaction no longer moves a partition's log start offset, as in Apache Kafka, whose cleaner never does. ListOffsets `earliest` and the `log_start_offset` in Fetch now stay at the log start through compaction, rather than moving to the first surviving batch. +- Fetch no longer sends a `current_leader` hint with `UNKNOWN_TOPIC_OR_PARTITION`, as in Apache Kafka. +- The broker's IPv6-to-IPv4 listener fallback recognizes "address family not + supported" on Windows. `is_address_family_unsupported` checked only the + Unix errno `libc::EAFNOSUPPORT`; Windows reports socket errors through + `WSAGetLastError`, so `raw_os_error()` there is `WSAEAFNOSUPPORT` (10047), + a different number, and a Windows host without IPv6 support failed to bind + `[::]` instead of falling back to `0.0.0.0`. diff --git a/CLAUDE.md b/CLAUDE.md index 5ca8da08c..30998d7e3 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -4,9 +4,9 @@ This file provides guidance to Claude Code (claude.ai/code) when working with co ## Project Overview -Tansu is a stateless, Apache Kafka-compatible broker written in Rust.

It then runs `cargo clean --workspace` on the clone, so only dependency artifacts carry over and the workspace crates rebuild from this worktree's sources. The recipe seeds no release, profiling or cross-target build, because that clean covers only the dev profile. It does nothing when `target/debug` already exists, and an interrupted seed leaves no `target/debug`, so a rerun starts again. Don't run it while the main checkout builds. Don't bring `target/` into a worktree any other way (`.worktreeinclude`, `worktree.symlinkDirectories`, a plain copy): those carry workspace-crate artifacts over, and cargo then reuses another checkout's code as the previous bullet describes. +- **`.env` is copied into Claude Code worktrees.** `.worktreeinclude` lists `.env`, so `claude --worktree` and subagent worktrees get a copy.

Any ambient data (auth state, cluster id, maximum frame size, etc.) that used to travel via `Context` now travels as a `rama::extensions::Extensions` bag carried *inside* the request wrapper type — see `nisshi-sans-io/src/input.rs` for `FrameInput`, `BodyInput`, `RequestInput`, and `BytesInput`, each a `{ value, extensions: Extensions }` pair. + +Two things about `Extensions` are easy to get wrong when touching this code: -Selected at compile time via feature flags, dispatched at runtime through `StorageContainer` enum: -- `memory://` - in-memory (feature: `dynostore`) -- `s3://` - S3/MinIO (feature: `dynostore`) -- `postgres://` - PostgreSQL (feature: `postgres`) -- `sqlite://` - libSQL/SQLite (feature: `libsql`) -- `slatedb://` - SlateDB KV store (feature: `slatedb`) +- **It is not fresh per request.** `Extensions` is `Arc`-backed; `.clone()` shares the same underlying store, and it is typically created once per connection (or per long-lived session, e.g. a consumer group) and reused/cloned across every request on it — not reconstructed per request the way the old per-call `Context` was. Code that inserts something once (e.g. `AuthenticationExtension` in `BytesFrameService`) must check `extensions.contains::()` before inserting, since on the 2nd+ request on the same connection it will already be there. Don't assert it's absent — that's a real invariant violation waiting to break multi-round-trip flows like SCRAM. +- **`.fork()` vs `.clone()`**: `.fork()` creates an isolated child scope — reads fall through to the parent, but inserts land only on the child and don't leak back up. Use `.fork()` when issuing an internal/side request that should see the caller's extensions but not mutate them (e.g. `nisshi-proxy`'s internal `DescribeConfigsRequest` lookup). Use `.clone()` (sharing the same store) when the request is part of the same logical session and should accumulate/observe state alongside sibling requests (e.g. `ConsumerGroupService`'s per-session `Extensions` field). +- **`Extension` requires an explicit impl** (or `#[derive(Extension)]`) — there is no blanket impl for arbitrary `T`, so a generic type can't automatically be stored as an extension unless its concrete implementors opt in. + +Per-handler dependencies (the `Coordinator` in `nisshi-broker/src/broker/group/*.rs`, the `Storage` handle `G` in `nisshi-storage/src/service/*.rs`) are still injected as plain struct fields (`struct FooService { coordinator: C }`) on each handler rather than through the `Extensions` bag — that's deliberate, not a leftover of the migration. + +### Storage Backends (`nisshi-storage`, `nisshi-storage-dynostore`, `nisshi-storage-null`, `nisshi-storage-slatedb`, `nisshi-storage-sql`) + +Selected at compile time via feature flags, dispatched at runtime through a `StorageFactory` trait, not an enum: `StorageContainer::builder()` (`nisshi-storage/src/lib.rs`) collects one `Arc` per enabled backend, and `.build()` picks the first whose `scheme()` regex matches the configured storage URL. Each backend crate implements the trait in its own `factory.rs`: +- `memory://`, `s3://`, `gs://` - ObjectStore-backed (`nisshi-storage-dynostore`, feature: `dynostore`) +- `null://` - stub backend, tracks topic metadata only, no message storage (`nisshi-storage-null`, always compiled in) +- `postgres://` - PostgreSQL (`nisshi-storage-sql`, feature: `postgres`) +- `sqlite://` - libSQL/SQLite (`nisshi-storage-sql`, feature: `libsql`) +- `slatedb://` - SlateDB KV store (`nisshi-storage-slatedb`, feature: `slatedb`) + +`RequestChannelService`'s `Storage` trait impl (`nisshi-storage/src/service.rs`) sends a `Request` over a channel and extracts the matching `Response` variant; every method does this via the `serve_and_extract!(self, request_expr, ResponseVariant)` macro rather than repeating the match/unwrap boilerplate - add new methods the same way. ### Broker Specifics - Node ID is always **111** (single-node, stateless design - this is intentional) -- Group coordination in `tansu-broker/src/coordinator/group/` +- Group coordination in `nisshi-broker/src/coordinator/group/` - `EnvVarExp` wrapper allows CLI args with `${VAR}` references expanded at parse time - All `Error` types implement `Clone` (non-Clone errors wrapped in `Arc`) ## Feature Flags -Default: `dynostore`, `postgres`, `libsql`, `slatedb`. Full build: `delta,dynostore,iceberg,libsql,parquet,postgres,slatedb`. +Default: `dynostore`, `postgres`, `libsql`, `slatedb`. The `just build`/`release` feature lists below omit `turso`, which the broker and storage crates enable by default. Full build: `delta,dynostore,iceberg,libsql,parquet,postgres,slatedb`. Lake features: `parquet`, `iceberg`, `delta` - enable writing schema-backed topics to data lake tables. ## Testing Notes - Tests use `cargo-nextest` (not `cargo test` for workspace tests) +- CI runs nextest with the `ci` profile in `.config/nextest.toml` (`NEXTEST_PROFILE=ci`), which kills a test still running after 5 minutes; local runs use the default profile - Test logs go to `logs//` (one file per test thread, dirs must exist) -- Integration tests require external services started via `just ci` +- Integration tests require external services started via `just ci` (postgres, minio, lakehouse); rerun `just ci` if those services are in a bad state, then `just test` to rerun the suite - Tests load `.env` via `dotenv().ok()` -- Tests in `tansu-broker` run against multiple backends: InMemory, Lite (libSQL), Postgres, SlateDb -- Tests with specific feature requirements use `required-features` in their `Cargo.toml` +- Tests in `nisshi-broker` run against multiple backends: InMemory, Lite (libSQL), Postgres, SlateDb +- `nisshi-broker`, `nisshi-sans-io` and `nisshi-service` each build one integration-test binary, `it`. To add a test file, create `tests/it/.rs` and declare it with `pub mod ;` in `tests/it/main.rs`; Cargo ignores undeclared files, and the `every_test_file_is_declared` test fails if one is missed. Gate backend-specific tests with `#[cfg(feature = "...")]` on a module, not `required-features`. Run one file's tests with a name filter, e.g. `cargo nextest run -p nisshi-broker --all-features -E 'test(/^fetch::/)'` +- Give each feature its own test file. Put the tests of one feature or one Kafka API in one file under `tests/it/`, named after it. Tests for a new feature go in a new file, not at the end of a file about another subject. A reader then finds them by name, and a name filter on the module selects them. +- `nisshi-smoke-test` runs the real Kafka CLI tools (in a `$KAFKA_IMAGE` container) against a broker, and stays out of `just test`; run it with `just smoke `. Its containers use the host network, so on macOS it needs Docker Desktop with host networking turned on. Its tests talk to the shared broker through `KafkaCli::shared()`, or start their own with `Broker::isolated()`, and each uses its own topic and group names (`nisshi_smoke_test::unique_name`). A test that applies only to some engines is gated with `#[cfg(feature = "")]` or `#[cfg(any(...))]` on the engines' features, never with `cfg(not(...))`, because `just clippy` turns every feature on and would never compile it. S3 runs only `topic_lifecycle`, selected by the `smoke-s3` profile in `.config/nextest.toml`. A test that fails because of an open bug is marked `#[ignore = ""]`, or `#[cfg_attr(feature = "", ignore = "...")]` if it fails only on some engines. CI skips it, local runs still run it (`run.sh` passes `--run-ignored all` outside CI), and the change that fixes the bug removes the attribute +- Single-file test targets with specific feature requirements (e.g. `nisshi-schema`'s `berg`) use `required-features` in their `Cargo.toml` ## CI Pipeline -GitHub Actions (`.github/workflows/ci.yml`): check -> fmt -> clippy -> build-storage (each feature independently) -> build-storage-lake (feature combinations) -> test (PostgreSQL 16/17/18 matrix) -> publish dry-run -> typos -> smoke tests (Java Kafka client, Kafka 3.7/3.8/3.9). +GitHub Actions (`.github/workflows/ci.yml`) runs in two tiers, gated by `ci-gate`, the single required check that fans in every other job: + +- **Tier A, every pull_request push:** `fmt`, `clippy` (which also runs `just doc`), `typos`, `third-party-license`, `test` (postgres:17 only), one non-experimental leg each of `compat-librdkafka` / `compat-franz-go`. +- **Tier B, once per merge-queue entry (`merge_group`) and on push to `main`:** the `build-storage` matrix (one build per storage engine, `turso` included) and `build-storage-lake` (one build per lake format on `dynostore`), `test` on postgres:16/17/18, the experimental compat legs, `cargo-publish-dry-run`, `src`, `release`, `package`, `smoke` (the `nisshi-smoke-test` suite: Kafka CLI tools from Kafka 3.9 and 4.3 against the packaged image on postgres, memory and s3, and against a source build on sqlite until #796 is fixed, on x86 and arm), `smoke-oldest-client` (the same suite with the Kafka 3.7 CLI tools, the oldest client CI tests, on every engine on x86 only); `smoke-report` puts every leg of both in one pass/fail grid in the step summary. + +Merging goes through a merge queue: "Merge when ready" queues the PR, the queue re-runs CI on it against the current tip of `main`, and squash-merges it if everything is green: the PR title becomes the commit's subject and the PR description its body. Tier B is skipped on same-repo PRs only while the `MERGE_QUEUE` repository variable is `on`; with it unset, they run everything. Fork PRs can't read the variable, so Tier B is always skipped on them and runs in the queue. The other required checks come from `codeql.yml`, `workflow-lint.yml`, `dependencies.yml` and `pr-title.yml` (the PR title must follow Conventional Commits; see `CONTRIBUTING.md`). + +On a pull_request, a `changes` job in `ci.yml`, `codeql.yml` and `dependencies.yml` skips the Rust jobs when every changed path is CI config those workflows don't read, or prose. The skip list is `.github/scripts/ci-changes.sh`, tested by `ci-changes.test.sh`; the `changes` jobs run the base branch's copy, so a PR can't widen its own skip list. ## Key Files @@ -117,9 +162,9 @@ GitHub Actions (`.github/workflows/ci.yml`): check -> fmt -> clippy -> build-sto | `compose.yaml` | Docker Compose: postgres, minio, grafana, jaeger, prometheus, lakehouse | | `etc/initdb.d/010-schema.sql` | PostgreSQL schema DDL | | `etc/schema/` | Sample schemas: `.avsc` (Avro), `.json` (JSON Schema), `.proto` (Protobuf) | -| `tansu-sans-io/message/` | Kafka JSON protocol descriptors (upstream, ~185 files) | -| `tansu-sans-io/build.rs` | Code generator: JSON descriptors -> Rust types | +| `nisshi-sans-io/message/` | Kafka JSON protocol descriptors (upstream, ~185 files) | +| `nisshi-sans-io/build.rs` | Code generator: JSON descriptors -> Rust types | ## Lint Configuration -Workspace-level in `Cargo.toml`: `clippy::all = warn`, `unsafe_code = forbid`, `non_ascii_idents = forbid`, `rust_2018_idioms = deny`, `unreachable_pub = warn`, `broken_intra_doc_links = deny`.

Runs the Apache Kafka command-line tools against a broker. +//! +//! [`KafkaCli`] runs each tool that [`Tool`] lists. Each tool has a module with two kinds of methods. Methods on +//! [`KafkaCli`] build the tool's command-line arguments, so a test names an action, such as +//! creating a topic, and does not list flags. Methods on [`Output`] read what the tool printed. A +//! method returns an [`Output`] typed by its command, so a test can call only the readers for +//! that command's output. +//! +//! Each method's doc names the Kafka APIs that the command is for. A command sends other requests +//! too, such as `ApiVersions` and `Metadata` first, and which ones it sends can change between +//! Kafka versions. +//! +//! The tools in `/opt/kafka/bin` run inside a container started from a Kafka image. The container +//! uses the host network, so the tools reach the broker at the address the broker advertises. Each +//! call returns the tool's exit code and output. +//! +//! Every time limit in the harness is a watchdog for a test that has already failed. A passing test +//! must stop when it reaches the result it expects, such as a record count, and must not wait for +//! a limit to expire. Each limit can then be well above the slowest passing run. +//! +//! Each call has two time limits.

Only `RangeAssignor` is implemented +(in `consumer/assignor/range.rs`). The other three are named but have no backing implementation, +so the broker can only honour clients that negotiate the `range` protocol. + +The `Assignor` enum strings (`"range"`, `"roundrobin"`, `"uniform"`, +`"cooperative-sticky"`) are already wired into `GroupConsumer::ASSIGNORS` (currently hard-coded +to `&[Assignor::Range]`); once the implementations exist that constant should be expanded. + +The `assignor.rs` module already defines a useful `Topition` struct (topic + partition_index as a +sorted key) and a `From<&MetadataResponse> for BTreeSet<Topition>` conversion — these should be +shared helpers for all assignors. + +--- + +## Kafka Assignor Semantics + +### Range (already implemented) + +For each topic independently, sort partitions, divide them into consecutive ranges. Members get +*allocation* or *allocation + 1* partitions. Members are processed in sorted order. + +**Key property**: consecutive partitions, per-topic, members with lower sort order get slightly +more when the division is uneven. Both topics independently → a member may get the same-indexed +partition across all its subscribed topics. + +The existing implementation has a subtle bug: it collapses all partition indices across all topics +into one `BTreeSet<i32>` (losing topic identity), then distributes the raw index numbers. The +current tests pass only because both topics in the test have the same partition count with +indices 0..N. For true range assignment each topic must be handled independently. This is noted +below but is **out of scope** for this plan — fix it in a follow-up. + +--- + +### RoundRobin + +**Protocol name**: `"roundrobin"` + +1. Collect the union of all (topic, partition) pairs subscribed by *any* member. +2. Sort the full set (by topic name then partition index) — i.e., iterate + `BTreeSet<Topition>`. +3. Distribute them across sorted members in round-robin order: topition[0] → member[0], + topition[1] → member[1], …, topition[N] → member[N % len]. +4. Each member only receives partitions for topics it has subscribed to; skip a topition + if the current member is not subscribed to that topic and move to the next member. + +**Result**: partitions interleaved across members. Every member gets roughly the same +count of partitions. + +When all members subscribe to the same topics, round-robin produces the most balanced +spread possible. When members have different subscriptions the skip logic is needed. + +--- + +### Uniform (Sticky) + +**Protocol name**: `"uniform"` (Tansu-specific alias, not in standard Kafka) + +Semantically identical to round-robin for the initial assignment. The "sticky" part matters +only during rebalance: try to keep existing assignments (`owned_partitions` from each member's +`ConsumerProtocolSubscription`) unchanged and only move partitions that are unbalanced or +belong to members who left the group. + +For a first implementation, treat uniform as round-robin (ignore stickiness). A follow-up +can add the rebalance-aware logic. + +--- + +### CooperativeSticky + +**Protocol name**: `"cooperative-sticky"` + +This is the incremental rebalance protocol (KIP-429). Its distinguishing feature is that +existing assignments are preserved across rebalances — the broker never revokes more than +it must. + +Algorithm: +1. Read each member's `owned_partitions` from their `ConsumerProtocolSubscription`. +2. Build a `target` assignment using round-robin over the new member list. +3. For each topition in the target assignment, if it is already owned by the target member, + keep it. Otherwise it must be moved, but only after the previous owner has revoked it in + a prior rebalance round (handled by the broker's join/sync state machine, not the + assignor itself). +4. For a first implementation: produce the same output as round-robin. The + `owned_partitions` data is available in `MemberMetadata` for future use. + +--- + +## Implementation Plan + +### Step 1 — Refactor `assignor.rs`: extract shared helpers + +The `Topition` struct and `BTreeSet<Topition>` builder are private to `assignor.rs`.
