Msgpack serialization/deserialization library for Python, written in Rust using PyO3 and rust-msgpack. Reboot of orjson. msgpack.org[Python]

Overview

ormsgpack

PyPI PyPI - Downloads

ormsgpack is a fast msgpack library for Python. It is a fork/reboot of orjson It serializes faster than msgpack-python and deserializes a bit slower (right now). It supports serialization of: dataclass, datetime, numpy, pydantic and UUID instances natively.

Its features and drawbacks compared to other Python msgpack libraries:

  • serializes dataclass instances natively.
  • serializes datetime, date, and time instances to RFC 3339 format, e.g., "1970-01-01T00:00:00+00:00"
  • serializes numpy.ndarray instances natively and faster.
  • serializes pydantic.BaseModel instances natively (disregards the configuration ATM).
  • serializes arbitrary types using a default hook

ormsgpack supports CPython 3.6, 3.7, 3.8, 3.9, and 3.10. ormsgpack does not support PyPy. Releases follow semantic versioning and serializing a new object type without an opt-in flag is considered a breaking change.

ormsgpack is licensed under both the Apache 2.0 and MIT licenses. The repository and issue tracker is github.com/aviramha/ormsgpack, and patches may be submitted there. There is a CHANGELOG available in the repository.

Usage

Install

To install a wheel from PyPI:

pip install --upgrade "pip>=19.3" # manylinux2014 support
pip install --upgrade ormsgpack

Notice that Linux environments with a pip version shipped in 2018 or earlier must first upgrade pip to support manylinux2014 wheels.

To build a wheel, see packaging.

Quickstart

This is an example of serializing, with options specified, and deserializing:

>>> import ormsgpack, datetime, numpy
>>> data = {
    "type": "job",
    "created_at": datetime.datetime(1970, 1, 1),
    "status": "🆗",
    "payload": numpy.array([[1, 2], [3, 4]]),
}
>>> ormsgpack.packb(data, option=ormsgpack.OPT_NAIVE_UTC | ormsgpack.OPT_SERIALIZE_NUMPY)
b'\x84\xa4type\xa3job\xaacreated_at\xb91970-01-01T00:00:00+00:00\xa6status\xa4\xf0\x9f\x86\x97\xa7payload\x92\x92\x01\x02\x92\x03\x04'
>>> ormsgpack.unpackb(_)
{'type': 'job', 'created_at': '1970-01-01T00:00:00+00:00', 'status': '🆗', 'payload': [[1, 2], [3, 4]]}

Serialize

def packb(
    __obj: Any,
    default: Optional[Callable[[Any], Any]] = ...,
    option: Optional[int] = ...,
) -> bytes: ...

packb() serializes Python objects to msgpack.

It natively serializes bytes, str, dict, list, tuple, int, float, bool, dataclasses.dataclass, typing.TypedDict, datetime.datetime, datetime.date, datetime.time, uuid.UUID, numpy.ndarray, and None instances. It supports arbitrary types through default. It serializes subclasses of str, int, dict, list, dataclasses.dataclass, and enum.Enum. It does not serialize subclasses of tuple to avoid serializing namedtuple objects as arrays. To avoid serializing subclasses, specify the option ormsgpack.OPT_PASSTHROUGH_SUBCLASS.

The output is a bytes object containing UTF-8.

The global interpreter lock (GIL) is held for the duration of the call.

It raises MsgpackEncodeError on an unsupported type. This exception message describes the invalid object with the error message Type is not JSON serializable: .... To fix this, specify default.

It raises MsgpackEncodeError on a str that contains invalid UTF-8.

It raises MsgpackEncodeError if a dict has a key of a type other than str or bytes, unless OPT_NON_STR_KEYS is specified.

It raises MsgpackEncodeError if the output of default recurses to handling by default more than 254 levels deep.

It raises MsgpackEncodeError on circular references.

It raises MsgpackEncodeError if a tzinfo on a datetime object is unsupported.

MsgpackEncodeError is a subclass of TypeError. This is for compatibility with the standard library.

default

To serialize a subclass or arbitrary types, specify default as a callable that returns a supported type. default may be a function, lambda, or callable class instance. To specify that a type was not handled by default, raise an exception such as TypeError.

>>> import ormsgpack, decimal
>>>
def default(obj):
    if isinstance(obj, decimal.Decimal):
        return str(obj)
    raise TypeError

>>> ormsgpack.packb(decimal.Decimal("0.0842389659712649442845"))
MsgpackEncodeError: Type is not JSON serializable: decimal.Decimal
>>> ormsgpack.packb(decimal.Decimal("0.0842389659712649442845"), default=default)
b'\xb80.0842389659712649442845'
>>> ormsgpack.packb({1, 2}, default=default)
ormsgpack.MsgpackEncodeError: Type is not msgpack serializable: set

The default callable may return an object that itself must be handled by default up to 254 times before an exception is raised.

It is important that default raise an exception if a type cannot be handled. Python otherwise implicitly returns None, which appears to the caller like a legitimate value and is serialized:

>>> import ormsgpack, json, rapidjson
>>>
def default(obj):
    if isinstance(obj, decimal.Decimal):
        return str(obj)

>>> ormsgpack.unpackb(ormsgpack.packb({"set":{1, 2}}, default=default))
{'set': None}

option

To modify how data is serialized, specify option. Each option is an integer constant in ormspgack. To specify multiple options, mask them together, e.g., option=ormspgack.OPT_NON_STR_KEYS | ormspgack.OPT_NAIVE_UTC.

OPT_NAIVE_UTC

Serialize datetime.datetime objects without a tzinfo as UTC. This has no effect on datetime.datetime objects that have tzinfo set.

>>> import ormsgpack, datetime
>>> ormsgpack.unpackb(ormsgpack.packb(
        datetime.datetime(1970, 1, 1, 0, 0, 0),
    ))
"1970-01-01T00:00:00"
>>> ormsgpack.unpackb(ormsgpack.packb(
        datetime.datetime(1970, 1, 1, 0, 0, 0),
        option=ormsgpack.OPT_NAIVE_UTC,
    ))
"1970-01-01T00:00:00+00:00"
OPT_NON_STR_KEYS

Serialize dict keys of type other than str. This allows dict keys to be one of str, int, float, bool, None, datetime.datetime, datetime.date, datetime.time, enum.Enum, and uuid.UUID. For comparison, the standard library serializes str, int, float, bool or None by default.

>>> import ormsgpack, datetime, uuid
>>> ormsgpack.packb(
        {uuid.UUID("7202d115-7ff3-4c81-a7c1-2a1f067b1ece"): [1, 2, 3]},
        option=ormsgpack.OPT_NON_STR_KEYS,
    )
>>> ormsgpack.packb(
        {datetime.datetime(1970, 1, 1, 0, 0, 0): [1, 2, 3]},
        option=ormsgpack.OPT_NON_STR_KEYS | ormsgpack.OPT_NAIVE_UTC,
    )

These types are generally serialized how they would be as values, e.g., datetime.datetime is still an RFC 3339 string and respects options affecting it.

This option has the risk of creating duplicate keys. This is because non-str objects may serialize to the same str as an existing key, e.g., {"1970-01-01T00:00:00+00:00": true, datetime.datetime(1970, 1, 1, 0, 0, 0): false}. The last key to be inserted to the dict will be serialized last and a msgpack deserializer will presumably take the last occurrence of a key (in the above, false). The first value will be lost.

OPT_OMIT_MICROSECONDS

Do not serialize the microsecond field on datetime.datetime and datetime.time instances.

>>> import ormsgpack, datetime
>>> ormsgpack.packb(
        datetime.datetime(1970, 1, 1, 0, 0, 0, 1),
    )
>>> ormsgpack.packb(
        datetime.datetime(1970, 1, 1, 0, 0, 0, 1),
        option=ormsgpack.OPT_OMIT_MICROSECONDS,
    )
OPT_PASSTHROUGH_DATACLASS

Passthrough dataclasses.dataclass instances to default. This allows customizing their output but is much slower.

>>> import ormsgpack, dataclasses
>>>
@dataclasses.dataclass
class User:
    id: str
    name: str
    password: str

def default(obj):
    if isinstance(obj, User):
        return {"id": obj.id, "name": obj.name}
    raise TypeError

>>> ormsgpack.packb(User("3b1", "asd", "zxc"))
b'\x83\xa2id\xa33b1\xa4name\xa3asd\xa8password\xa3zxc'
>>> ormsgpack.packb(User("3b1", "asd", "zxc"), option=ormsgpack.OPT_PASSTHROUGH_DATACLASS)
TypeError: Type is not msgpack serializable: User
>>> ormsgpack.packb(
        User("3b1", "asd", "zxc"),
        option=ormsgpack.OPT_PASSTHROUGH_DATACLASS,
        default=default,
    )
b'\x82\xa2id\xa33b1\xa4name\xa3asd'
OPT_PASSTHROUGH_DATETIME

Passthrough datetime.datetime, datetime.date, and datetime.time instances to default. This allows serializing datetimes to a custom format, e.g., HTTP dates:

>>> import ormsgpack, datetime
>>>
def default(obj):
    if isinstance(obj, datetime.datetime):
        return obj.strftime("%a, %d %b %Y %H:%M:%S GMT")
    raise TypeError

>>> ormsgpack.packb({"created_at": datetime.datetime(1970, 1, 1)})
b'\x81\xaacreated_at\xb31970-01-01T00:00:00'
>>> ormsgpack.packb({"created_at": datetime.datetime(1970, 1, 1)}, option=ormsgpack.OPT_PASSTHROUGH_DATETIME)
TypeError: Type is not msgpack serializable: datetime.datetime
>>> ormsgpack.packb(
        {"created_at": datetime.datetime(1970, 1, 1)},
        option=ormsgpack.OPT_PASSTHROUGH_DATETIME,
        default=default,
    )
b'\x81\xaacreated_at\xbdThu, 01 Jan 1970 00:00:00 GMT'

This does not affect datetimes in dict keys if using OPT_NON_STR_KEYS.

OPT_PASSTHROUGH_SUBCLASS

Passthrough subclasses of builtin types to default.

>>> import ormsgpack
>>>
class Secret(str):
    pass

def default(obj):
    if isinstance(obj, Secret):
        return "******"
    raise TypeError

>>> ormsgpack.packb(Secret("zxc"))
b'\xa3zxc'
>>> ormsgpack.packb(Secret("zxc"), option=ormsgpack.OPT_PASSTHROUGH_SUBCLASS)
TypeError: Type is not msgpack serializable: Secret
>>> ormsgpack.packb(Secret("zxc"), option=ormsgpack.OPT_PASSTHROUGH_SUBCLASS, default=default)
b'\xa6******'

This does not affect serializing subclasses as dict keys if using OPT_NON_STR_KEYS.

OPT_SERIALIZE_NUMPY

Serialize numpy.ndarray instances. For more, see numpy.

OPT_SERIALIZE_PYDANTIC

Serialize pydantic.BaseModel instances. Right now it ignores the config (str transformations), support might be added later.

OPT_UTC_Z

Serialize a UTC timezone on datetime.datetime instances as Z instead of +00:00.

>>> import ormsgpack, datetime
>>> ormsgpack.packb(
        datetime.datetime(1970, 1, 1, 0, 0, 0, tzinfo=datetime.timezone.utc),
    )
b'"1970-01-01T00:00:00+00:00"'
>>> ormsgpack.packb(
        datetime.datetime(1970, 1, 1, 0, 0, 0, tzinfo=datetime.timezone.utc),
        option=ormsgpack.OPT_UTC_Z
    )
b'"1970-01-01T00:00:00Z"'

Deserialize

def unpackb(__obj: Union[bytes, bytearray, memoryview], / , option=None) -> Any: ...

unpackb() deserializes msgpack to Python objects. It deserializes to dict, list, int, float, str, bool, bytes and None objects.

bytes, bytearray, memoryview input are accepted.

ormsgpack maintains a cache of map keys for the duration of the process. This causes a net reduction in memory usage by avoiding duplicate strings. The keys must be at most 64 bytes to be cached and 512 entries are stored.

The global interpreter lock (GIL) is held for the duration of the call.

It raises MsgpackDecodeError if given an invalid type or invalid msgpack.

MsgpackDecodeError is a subclass of ValueError.

option

unpackb() supports the OPT_NON_STR_KEYS option, that is similar to original msgpack's strict_map_keys=False. Be aware that this option is considered unsafe and disabled by default in msgpack due to possibility of HashDoS.

Types

dataclass

ormsgpack serializes instances of dataclasses.dataclass natively. It serializes instances 40-50x as fast as other libraries and avoids a severe slowdown seen in other libraries compared to serializing dict.

It is supported to pass all variants of dataclasses, including dataclasses using __slots__, frozen dataclasses, those with optional or default attributes, and subclasses. There is a performance benefit to not using __slots__.

Dataclasses are serialized as maps, with every attribute serialized and in the order given on class definition:

>>> import dataclasses, ormsgpack, typing

@dataclasses.dataclass
class Member:
    id: int
    active: bool = dataclasses.field(default=False)

@dataclasses.dataclass
class Object:
    id: int
    name: str
    members: typing.List[Member]

>>> ormsgpack.packb(Object(1, "a", [Member(1, True), Member(2)]))
b'\x83\xa2id\x01\xa4name\xa1a\xa7members\x92\x82\xa2id\x01\xa6active\xc3\x82\xa2id\x02\xa6active\xc2'

Users may wish to control how dataclass instances are serialized, e.g., to not serialize an attribute or to change the name of an attribute when serialized. ormsgpack may implement support using the metadata mapping on field attributes, e.g., field(metadata={"json_serialize": False}), if use cases are clear.

datetime

ormsgpack serializes datetime.datetime objects to RFC 3339 format, e.g., "1970-01-01T00:00:00+00:00". This is a subset of ISO 8601 and compatible with isoformat() in the standard library.

>>> import ormsgpack, datetime, zoneinfo
>>> ormsgpack.packb(
    datetime.datetime(2018, 12, 1, 2, 3, 4, 9, tzinfo=zoneinfo.ZoneInfo('Australia/Adelaide'))
)
>>> ormsgpack.unpackb(_)
"2018-12-01T02:03:04.000009+10:30"
>>> ormsgpack.packb(
    datetime.datetime.fromtimestamp(4123518902).replace(tzinfo=datetime.timezone.utc)
)
>>> ormsgpack.unpackb(_)
"2100-09-01T21:55:02+00:00"
>>> ormsgpack.packb(
    datetime.datetime.fromtimestamp(4123518902)
)
>>> ormsgpack.unpackb(_)
"2100-09-01T21:55:02"

datetime.datetime supports instances with a tzinfo that is None, datetime.timezone.utc, a timezone instance from the python3.9+ zoneinfo module, or a timezone instance from the third-party pendulum, pytz, or dateutil/arrow libraries.

datetime.time objects must not have a tzinfo.

>>> import ormsgpack, datetime
>>> ormsgpack.packb(datetime.time(12, 0, 15, 290))
>>> ormsgpack.unpackb(_)
"12:00:15.000290"

datetime.date objects will always serialize.

>>> import ormsgpack, datetime
>>> ormsgpack.packb(datetime.date(1900, 1, 2))
>>> ormsgpack.unpackb(_)
"1900-01-02"

Errors with tzinfo result in MsgpackEncodeError being raised.

It is faster to have ormsgpack serialize datetime objects than to do so before calling packb(). If using an unsupported type such as pendulum.datetime, use default.

To disable serialization of datetime objects specify the option ormsgpack.OPT_PASSTHROUGH_DATETIME.

To use "Z" suffix instead of "+00:00" to indicate UTC ("Zulu") time, use the option ormsgpack.OPT_UTC_Z.

To assume datetimes without timezone are UTC, se the option ormsgpack.OPT_NAIVE_UTC.

enum

ormsgpack serializes enums natively. Options apply to their values.

>>> import enum, datetime, ormsgpack
>>>
class DatetimeEnum(enum.Enum):
    EPOCH = datetime.datetime(1970, 1, 1, 0, 0, 0)
>>> ormsgpack.packb(DatetimeEnum.EPOCH)
>>> ormsgpack.unpackb(_)
"1970-01-01T00:00:00"
>>> ormsgpack.packb(DatetimeEnum.EPOCH, option=ormsgpack.OPT_NAIVE_UTC)
>>> ormsgpack.unpackb(_)
"1970-01-01T00:00:00+00:00"

Enums with members that are not supported types can be serialized using default:

>>> import enum, ormsgpack
>>>
class Custom:
    def __init__(self, val):
        self.val = val

def default(obj):
    if isinstance(obj, Custom):
        return obj.val
    raise TypeError

class CustomEnum(enum.Enum):
    ONE = Custom(1)

>>> ormsgpack.packb(CustomEnum.ONE, default=default)
>>> ormsgpack.unpackb(_)
1

float

ormsgpack serializes and deserializes double precision floats with no loss of precision and consistent rounding.

int

ormsgpack serializes and deserializes 64-bit integers by default. The range supported is a signed 64-bit integer's minimum (-9223372036854775807) to an unsigned 64-bit integer's maximum (18446744073709551615).

numpy

ormsgpack natively serializes numpy.ndarray and individual numpy.float64, numpy.float32, numpy.int64, numpy.int32, numpy.int8, numpy.uint64, numpy.uint32, and numpy.uint8 instances. Arrays may have a dtype of numpy.bool, numpy.float32, numpy.float64, numpy.int32, numpy.int64, numpy.uint32, numpy.uint64, numpy.uintp, or numpy.intp. ormsgpack is faster than all compared libraries at serializing numpy instances. Serializing numpy data requires specifying option=ormsgpack.OPT_SERIALIZE_NUMPY.

>>> import ormsgpack, numpy
>>> ormsgpack.packb(
        numpy.array([[1, 2, 3], [4, 5, 6]]),
        option=ormsgpack.OPT_SERIALIZE_NUMPY,
)
>>> ormsgpack.unpackb(_)
[[1,2,3],[4,5,6]]

The array must be a contiguous C array (C_CONTIGUOUS) and one of the supported datatypes.

If an array is not a contiguous C array or contains an supported datatype, ormsgpack falls through to default. In default, obj.tolist() can be specified. If an array is malformed, which is not expected, ormsgpack.MsgpackEncodeError is raised.

Reproducing

The above was measured using Python 3.7.9 on Azure Linux VM (x86_64) with ormsgpack 0.2.1 and msgpack 1.0.2.

The latency results can be reproduced using ./scripts/benchmark.sh and graphs using pytest --benchmark-histogram benchmarks/bench_*.

Questions

Why can't I install it from PyPI?

Probably pip needs to be upgraded to version 20.3 or later to support the latest manylinux_x_y or universal2 wheel formats.

Will it deserialize to dataclasses, UUIDs, decimals, etc or support object_hook?

No. This requires a schema specifying what types are expected and how to handle errors etc. This is addressed by data validation libraries a level above this.

Will it support PyPy?

If someone implements it well.

Packaging

To package ormsgpack requires Rust on the nightly channel and the maturin build tool. maturin can be installed from PyPI or packaged as well. This is the simplest and recommended way of installing from source, assuming rustup is available from a package manager:

rustup default nightly
pip wheel --no-binary=ormsgpack ormsgpack

This is an example of building a wheel using the repository as source, rustup installed from upstream, and a pinned version of Rust:

pip install maturin
curl https://sh.rustup.rs -sSf | sh -s -- --default-toolchain nightly-2021-05-25 --profile minimal -y
export RUSTFLAGS="-C target-cpu=k8"
maturin build --no-sdist --release --strip --manylinux off
ls -1 target/wheels

Problems with the Rust nightly channel may require pinning a version. nightly-2021-05-25 is known to be ok.

ormsgpack is tested for amd64 and aarch64 on Linux, macOS, and Windows. It may not work on 32-bit targets. It has recommended RUSTFLAGS specified in .cargo/config so it is recommended to either not set RUSTFLAGS or include these options.

There are no runtime dependencies other than libc.

Comments
  • Passthrough int and tuple

    Passthrough int and tuple

    We have developped some functionality for ormsgpack that is currently not supported, but you might want to support:

    This PR adds:

    • Optional passthrough of Python integers, such that also ints larger than 64 bits can be serialized using a default function. Currently they can not be serialized in any way, and by adding this option, the library doesn't get more complicated, but serialization of larger integers is allowed. (Updated tests accordingly)
    • Optional passthrough of Python tuples, such that they can also be deserialized as tuples. Again, no complications for the library, but just leaving it to the default option. (Updated tests accordingly)
    • An OPT_NO_OPT constant, for convenience of the user (with value 0).
    • Fixed typing of the option parameter, since in fact only ints are allowed, and None-values give errors.

    Please let me know if you would like to add (part of) this functionality.

  • BIGINT passthrough semantics

    BIGINT passthrough semantics

    The new BIGINT_PASSTHROUGH in 1.1.0 seems to be a bit confusing. Originally I thought it uses passthrough for the ints ormsgpack simply rejected before but it turns out that it also passes through u64 which previously was efficiently converted to the uint64 msgpack format. I think the library should use msgpack formats if possible and the passthrough should extend that functionality instead of changing it. So I propose that passthrough would happen only if the int can't fit into either int64 or uint64, which means it can't be converted to a native msgpack type and needs to be encoded.

  • Broken typing in latest (0.3.2)

    Broken typing in latest (0.3.2)

    I saw you updated maturin in #23 so it can generate type stubs for you but there was no release build triggered and as such the latest version on PyPI still has broken types, because it's missing the "py.typed" file.

    I don't know if you'd prefer to include the "py.typed" file or remove the .pyi stub and let maturin generate everything, but either way it'd be nice to release a fixed version. If you let me know which you'd prefer I can make a quick PR.

    Source code(zip)
  • 0.3.0(Jun 13, 2021)

    Added

    • unpackb now accepts keyword argument option with argument OPT_NON_STR_KEYS. This option will let ormsgpack unpack dictionaries with non-str keys. Be aware that this option is considered unsafe and disabled by default in msgpack due to possibility of HashDoS.
    • packb now is able to pack dictionaries with tuples as keys. unpackb is able to unpack such dictionaries. Both requires OPT_NON_STR_KEYS.

    • Grouped benchmarks in a pattern that should make more sense.

    Fixed

    • orjson.packb with option argument as ormsgpack.OPT_NON_STR_KEYS serializes bytes key into tuple of integers instead of using bin type. This also resulted in assymetrical packb/unpackb.

    Misc

    • Added --no-index to pip install ormsgpack to avoid installing from PyPI on CI.
    Source code(tar.gz)

A weekly dive into commonly used modules in the Rust ecosystem, with story flavor!

The goal of this project is to bring the same concept as PyMOTW to the Rust world. PyMOTW was an invaluable resource for me when I was learning Python years ago, and I hope that I can help someone in a similar way. Each week we'll dive into a module and explore some of the functionality that we can find there while following along the adventures of some colourful characters.
