python-libuuid - Faster UUID generation using libuuid

A Python C extension for faster generation of UUID objects. It supports libuuid-based generation of version 1 and 4 UUIDs. The library is fully compatible with the standard uuid module, while also providing specialized, optimized, functions for generating UUID strings.

python-libuuid is roughly 8-10 times faster than the pure-python version.

It's basically just a thin Cython wrapper around libuuid by Theo Tso.

Installation

You can install python-libuuid either via the Python Package Index (PyPI) or from source.

To install using pip:

$ pip install python-libuuid

To install using easy_install:

$ easy_install python-libuuid

If you have downloaded a source tarball you can install it by doing the following,:

$ python setup.py build
# python setup.py install # as root

Usage / Examples

The libuuid module provides a similar interface to uuid, resulting in fully compatible UUID objects. libuuid.UUID is also a subclass of uuid.UUID, so existing code using isinstance will continue to work.

>>> import libuuid
>>> libuuid.uuid1()
UUID('a3a32410-940a-11df-8ead-002219990fd7')
>>> libuuid.uuid4()
UUID('85651a1f-118f-480d-a116-526b2dd37322')

Furthermore, libuuid has a few extra utility functions not available in uuid. These are handy when you don't need a "full" UUID object, but just need the byte representation. The _bytes functions have less overhead than the common interface.

>>> libuuid.uuid1_bytes()
'\x05f\xe1d\x94\x0b\x11\xdf\x8e\xad\x00"\x19\x99\x0f\xd7'
>>> libuuid.uuid4_bytes()
'\x05f\xe1d\x94\x0b\x11\xdf\x8e\xad\x00"\x19\x99\x0f\xd7'

Gotchas

  • libuuid only provides random (version 4) and time based (version 1) UUIDs.
  • Calling libuuid.uuid1 with node or clock_seq is not supported, and will silently fall back to the uuid.UUID implementation for compatibility.
  • Only tested on Linux. It should work on any platform, but e2fsprogs is probably just readily available on Linux distributions.

python-libuuid - Faster UUID generation using libuuid
A Python C extension for faster generation of UUID objects. It supports
libuuid-based generation of version 1 and 4 UUIDs. The library is fully
compatible with the standard uuid module, while also providing specialized,
optimized, functions for generating UUID strings.
python-libuuid is roughly 8-10 times faster than the pure-python version.
It's basically just a thin Cython wrapper around libuuid by Theo Tso.
Installation
You can install python-libuuid either via the Python Package Index (PyPI)
or from source.
To install using pip:
$ pip install python-libuuid

To install using easy_install:
$ easy_install python-libuuid

If you have downloaded a source tarball you can install it by doing the
following,:
$ python setup.py build
# python setup.py install # as root

Usage / Examples
The libuuid module provides a similar interface to uuid, resulting in fully
compatible UUID objects. libuuid.UUID is also a subclass of uuid.UUID,
so existing code using isinstance will continue to work.
>>> import libuuid
>>> libuuid.uuid1()
UUID('a3a32410-940a-11df-8ead-002219990fd7')
>>> libuuid.uuid4()
UUID('85651a1f-118f-480d-a116-526b2dd37322')
Furthermore, libuuid has a few extra utility functions not available in
uuid. These are handy when you don't need a "full" UUID object, but just
need the byte representation. The _bytes functions have less overhead than
the common interface.
>>> libuuid.uuid1_bytes()
'\x05f\xe1d\x94\x0b\x11\xdf\x8e\xad\x00"\x19\x99\x0f\xd7'
>>> libuuid.uuid4_bytes()
'\x05f\xe1d\x94\x0b\x11\xdf\x8e\xad\x00"\x19\x99\x0f\xd7'
Gotchas
  • libuuid only provides random (version 4) and time based (version 1) UUIDs.
  • Calling libuuid.uuid1 with node or clock_seq is not supported, and will
silently fall back to the uuid.UUID implementation for compatibility.
  • Only tested on Linux. It should work on any platform, but e2fsprogs is
probably just readily available on Linux distributions.
