fix(sdk): remove five dead wire forms, register TXN/FT.AGGREGATE, guard the SDK in CI - #501
Conversation
…rd the SDK in CI
The Rust SDK shipped five public helpers that Moon rejects on their first
round trip, every time, for the whole published lifetime of the crate. No
caller can have depended on their behaviour — only on them compiling.
push_partitioned / pop_partitioned sent MQ.PUSH / MQ.POP as command names
upsert sent FT.UPSERT
snapshot_at_packed sent TEMPORAL.SNAPSHOT_AT <hlc> (takes none)
release_snapshot sent bare TEMPORAL.INVALIDATE (takes three)
The last two are the interesting ones: both name commands Moon really has,
so a name-level audit had already cleared them. release_snapshot was found
by the new round-trip guard on its FIRST live run, after review had passed
the file. It has no replacement because its premise was false — TEMPORAL.
SNAPSHOT_AT never pinned a connection to a snapshot view, it records a
shard-global wall_ms -> LSN binding that AS_OF resolves later, so no pin is
taken and none can be released. snapshot_at's doc, which described the
imaginary pin, is corrected.
upsert is not reimplemented over the real wire form because there isn't a
faithful one: Moon indexes a vector by HSET-ing a hash whose vector FIELD
NAME comes from the index definition, and the signature never carried it.
Guessing would trade a loud error for a silent wrong write.
TXN was NOT removed. An earlier probe appeared to show it dead; the probe
was wrong (zsh does not word-split an unquoted parameter expansion, so the
server received one argument literally named "TXN BEGIN"). txn_begin /
txn_commit / txn_abort are correct and stay.
Server side, two commands were undiscoverable because intercepts serve them
before the metadata table is consulted: TXN and FT.AGGREGATE are now
registered, so COMMAND INFO and COMMAND COUNT (265 -> 267) report them.
Registration is metadata only and reroutes neither. Separately, a bare TXN
answered "unknown command 'TXN'" — false, since the command exists, and it
misleads a driver into concluding Moon has no cross-store transactions. It
now answers an arity/subcommand error, the shape Redis uses for container
commands.
moondb.__version__ reported 0.1.0 while the package published as 0.1.1, and
the test covering it asserted the same stale literal, so the suite stayed
green for two releases while every caller read the wrong number. It is now
derived from distribution metadata (falling back to pyproject.toml for an
uninstalled checkout) and the test asserts the derivation, not the value.
The root cause of all six defects is that sdk/ had no CI of any kind. Three
guards now run:
tests/sdk_wire_forms.rs command-NAME sweep over both SDK trees
sdk/rust/tests/round_trip.rs all 168 public helpers, live, per owning type
sdk/python/tests/test_version.py version derivation
The last two are wired into the client-compat job — the one that already
builds Moon and proves a real client works against it.
Two findings from attacking the guards rather than trusting them:
- Reordering MqClient::create's arguments left the round trip GREEN. Its
predicate matched the phrase "unknown subcommand" while Moon says
"unknown MQ subcommand". Widened to loose tokens; the mutant now fails
while the name sweep stays green, which is the point of having both.
- Coverage keyed on bare fn name would let a future NewClient::search
inherit "covered" from VectorClient::search. Keyed on Type::fn instead,
and swf4b fails if the round trip drives fewer than the crate declares
(proved by dropping one call: "1 of 168 ... VectorClient::compact").
The name sweep also failed the tokio leg, correctly: graph and text-index
are DEFAULT features that --no-default-features drops, so GRAPH.* and
FT.AGGREGATE are legitimately absent there. It now consults cfg! and
announces what it skipped instead of shrinking silently.
BREAKING CHANGE: moondb 0.2.1 -> 0.3.0 removes five pub methods. Each is
documented in place with its replacement, and in the CHANGELOG.
Evidence:
monoio (default): lib 4641 pass; sdk_wire_forms 4/4; batch_protocol 7/7
tokio+jemalloc: lib 3807 pass; sdk_wire_forms 3 pass + 1 correctly
ignored; batch_protocol 7/7
sdk/rust: round_trip 2/2 live, 168/168 helpers, zero rejections
sdk/python: test_version 3/3; 7 pre-existing test_text.py async
failures unchanged from HEAD
fmt + clippy clean on both feature legs

Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to Although the PR removes invalid SDK wire forms and adds coverage, the current head still has a high-impact protocol-safety flaw, a feature-disabled build where FT.AGGREGATE is advertised but unusable, a supported-Python packaging failure, and a shared-runner CI setup that can validate the wrong server; merge should be blocked until these issues are fixed or explicitly accepted by owners.

… run
The version guard was written pytest-style and the CI step installed pytest.
Neither works on the client-compat runner, verified on the runner rather than
assumed:
- Ubuntu 24.04 / Python 3.14 ships PEP 668 EXTERNALLY-MANAGED, so
`pip install --user pytest` aborts with externally-managed-environment.
- `python3.14-venv` is not installed, so `python3 -m venv` fails at
ensurepip — the obvious fallback is also unavailable.
Rewritten as `unittest.TestCase`, needing nothing beyond the standard library,
and the step now runs `python3 -m unittest discover` — the same form the two
differ steps in this job already use. pytest still collects TestCase classes,
so local development is unchanged.
Caught before CI reached the step by rehearsing it on the runner. Re-verified
there in both directions: 3/3 green, and 2 failures when `__version__` is
reverted to a hardcoded literal.

Resolve the SDK clippy CI gap before recording a PASS.
The task records three sdk/rust clippy::too_many_arguments errors and says SDK clippy is not in CI. This conflicts with the repository requirement for zero-warning clippy coverage in CI for both runtime feature configurations. Fix the errors and add the SDK checks, or obtain an explicit approved exception before recording a PASS.
As per coding guidelines, "**/*.rs: Run and maintain formatting, clippy with zero warnings, both runtime feature configurations, and Rust 1.94 compatibility in CI."

Declare the Python 3.10 TOML parser dependency.
requires-python = ">=3.10" but the runtime dependencies do not include tomli. On Python 3.10, _resolve_version() then returns "0.0.0.unknown" instead of the version in pyproject.toml. Add a conditional tomli dependency for Python versions below 3.11, or remove Python 3.10 support. sdk/python/tests/test_client.py also imports tomli directly.

PEP 440 version specification local version identifier plus sign 0.0.0+unknown invalid version
💡 Result:
The version string 0.0.0+unknown is a valid PEP 440 version [1][2][3]. According to PEP 440, a local version identifier is constructed by appending a plus sign (+) followed by a local version label to a public version identifier [4][5]. In the string 0.0.0+unknown: - 0.0.0 is the public version identifier. - + indicates the start of the local version identifier. - unknown is the local version label. The local version label "unknown" consists of ASCII letters, which is permitted under PEP 440's requirements for local version labels (which must consist of ASCII letters, digits, and periods, and must start and end with an ASCII letter or digit) [4][5][6]. Because 0.0.0+unknown conforms to these syntactic rules, it is a valid PEP 440 version string. It is commonly used by Python developers as a sentinel value in code to provide a fallback version when a package's metadata cannot be retrieved—for instance, when the package is imported from a source checkout that has not been installed [1][2][3]. While 0.0.0+unknown is a valid PEP 440 version, local version identifiers themselves are generally not permitted when publishing packages to public index servers like PyPI [4][7]. However, this restriction applies to the publication of distributions, not to the validity of the version string format itself or its use in local code environments [4][8].

Use a PEP 440-compatible fallback and test the fallback path. 0.0.0.unknown is not PEP 440-compatible, while 0.0.0+unknown is. The current regex accepts the invalid value and rejects the valid replacement. Use a PEP 440 parser in sdk/python/tests/test_version.py. Add a focused test that forces both metadata and pyproject.toml lookup to fail, because the current test reads pyproject.toml and does not exercise the final fallback.

Exclude FT.AGGREGATE from metadata when text-index is disabled.
ft_aggregate and its handlers are feature-gated, but the COMMAND_META entry is unconditional. Without text-index, COMMAND INFO FT.AGGREGATE returns a 10-field specification while execution returns ERR unknown FT.* command. A lookup-only guard is insufficient because COMMAND, COMMAND COUNT, COMMAND LIST, and COMMAND DOCS access COMMAND_META directly. Use feature-specific metadata or filter every metadata surface. Update swf3_intercept_dispatched_commands_are_introspectable to skip FT.AGGREGATE when the feature is disabled.

Sanitize the echoed TXN subcommand token.
If the token contains \r or \n, Frame::Error writes it verbatim and injects another RESP reply. Strip control bytes and limit the token length, or omit the token.

remove CR/LF and other control bytes, and cap its length before interpolating it
into the Frame::Error message; alternatively omit the token when unsafe.

What
The Rust SDK shipped five public helpers that Moon rejects on their first round trip, every
time, for the whole published lifetime of the crate. No caller can have depended on their
behaviour — only on them compiling.
MqClient::push_partitionedMQ.PUSH(a command name)unknown commandMqClient::pushMqClient::pop_partitionedMQ.POP(a command name)unknown commandMqClient::popVectorClient::upsertFT.UPSERTunknown FT.* commandFT.CREATE, thenHSETthe index's vector fieldTemporalClient::snapshot_at_packedTEMPORAL.SNAPSHOT_AT <hlc>wrong number of argumentssnapshot_atTemporalClient::release_snapshotTEMPORAL.INVALIDATE(no args)wrong number of argumentsThe last two are the interesting ones: both name commands Moon really has, so a name-level
audit had already cleared them.
release_snapshotwas found by the new round-trip guard on itsfirst live run, after review had passed the file.
release_snapshothas no replacement because its premise was false.TEMPORAL.SNAPSHOT_ATneverpinned a connection to a snapshot view — it records a shard-global
wall_ms → LSNbinding thatAS_OFresolves later (src/server/conn/shared.rs:168is its only reader). No pin is taken, sonone can be released.
snapshot_at's doc, which described the imaginary pin, is corrected.upsertis not reimplemented over the real wire form because there isn't a faithful one: Moonindexes a vector by
HSET-ing a hash whose vector FIELD NAME comes from the index definition, andthe signature never carried it. Guessing would trade a loud error for a silent wrong write.
TXNwas NOT removed. An earlier probe appeared to show it dead; the probe was wrong — zshdoes not word-split an unquoted parameter expansion, so the server received one argument literally
named
TXN BEGIN.txn_begin/txn_commit/txn_abortare correct and stay.Server-side
Two commands were undiscoverable because intercepts serve them before the metadata table is
consulted.
TXNandFT.AGGREGATEare now registered, soCOMMAND INFO/COMMAND COUNT(265 → 267) report them. Registration is metadata only and reroutes neither.
Separately, a bare
TXNansweredunknown command 'TXN'— false, since the command exists, and itmisleads a driver into concluding Moon has no cross-store transactions at all. It now answers an
arity/subcommand error, the shape Redis uses for container commands and the one driver error
handling keys on.
Python
moondb.__version__reported0.1.0while the package published as0.1.1— and the testcovering it asserted the same stale literal, so the suite stayed green for two releases while
every caller read the wrong number. Now derived from distribution metadata (falling back to
pyproject.tomlfor an uninstalled checkout); the test asserts the derivation, not the value.Root cause:
sdk/had no CI of any kindThat is why all six defects shipped. Three guards now run:
tests/sdk_wire_forms.rs— command-NAME sweep over both SDK treessdk/rust/tests/round_trip.rs— all 168 public helpers, live, keyed per owning typesdk/python/tests/test_version.py— version derivationThe last two are wired into the
client-compatjob, the one that already builds Moon and proves areal client works against it.
Attacking the guards rather than trusting them
Two findings that only came from trying to break them:
MqClient::create's arguments left the round trip GREEN. Its predicate matchedthe phrase
"unknown subcommand", and Moon says"unknown MQ subcommand". Widened to two loosetokens; the mutant now fails while the name sweep stays green — which is the point of having
both guards.
NewClient::searchinherit "covered"status from
VectorClient::search. Keyed onType::fninstead, andswf4bfails if the roundtrip drives fewer than the crate declares. Proved non-vacuous by dropping one call:
1 of 168 ... VectorClient::compact.The name sweep also failed the tokio leg, correctly:
graphandtext-indexare DEFAULTfeatures that
--no-default-featuresdrops, soGRAPH.*andFT.AGGREGATEare legitimatelyabsent there. It now consults
cfg!and announces what it skipped instead of shrinkingsilently. Had that not been caught locally it would have turned CI red on merge.
Breaking change
moondb0.2.1 → 0.3.0. Each removed method is documented in place with its replacement, andin the CHANGELOG.
