All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[1.5.2]

  • macOS Apple Silicon prebuilt binaries
  • Tested with Node.js 22

[1.5.1] 2024-04-01

  • Fix the build with recent Node.js versions after node_api_nogc_env in Node.js 18.20

[1.5.0] 2024-02-08

  • Add Python 3.12 support and upgrade the built-in Python to 3.12.2
  • Drop Node.js 14 support

[1.4.3] 2023-10-29

  • Fix #104, do not mess up the loading of additional binary modules after pymport

[1.4.2] 2023-08-28

  • Builtin Python updated to 3.12.2

[1.4.1] 2023-05-01

  • Node.js 20 support
  • Builtin Python updated to 3.10.11
  • Fix [#78], a single Buffer argument is interpreted as kwargs

[1.4.0] 2023-01-22

  • The new minimum supported versions of Node.js are now v12.22.0, v14.17.0, v16.0.0

New Features

  • Allow limiting the depth of the recursion of toJS()
  • Allow disabling of the generic Buffer protocol transformation to toJS()
  • Add PyObject.prototype.map method compatible with Array.prototype.map
  • Proxified functions are now also Proxy objects, resolves #58
  • PyObject.item() now returns undefined instead of throwing an exception when an element cannot be retrieved by []
  • Allow enabling of debug output via the environment (PYMPORT_DEBUG_sys vars)
  • Improved bootstrap and shutdown allowing to load and unload the addon in worker_threads, partially resolves #69

Bug Fixes

  • Fix #66, race condition can result in an abort when using pymport with worker_threads
  • Fix #40, patch _sysconfigdata after installation
  • Fix #70, random crash in a worker_thread
  • Fix #69, pymport leaks TLS memory when used in a worker_thread

[1.3.1] 2023-01-07

  • Fix #63, restore the executable bit of pympip3
  • Fix #40, revert and lock setuptools for the builtin interpreter to 65.1.1 due to setuptools#3589
  • Fix #60, proxified objects are not GCed
  • Fix #48, do not consider falsy properties as being undefined
  • Fix #50, proxified .toString() is not identical to PyObject.toString()

[1.3.0] 2022-12-22

New Features

  • Builtin Python 3.10.9
  • Multithreading safety
  • callAsync method allowing asynchronous calling of Python functions
  • On Linux and macOS, the builtin Python interpreter includes static versions of OpenSSL and libffi, this ensures better compatibility at the price of disabling the OpenSSL extensions supporting dedicated crypto hardware - this restriction does not apply if pymport is rebuilt from source
  • Named ES6 exports
  • Add PyObject.with implementing Python with
  • Return the Python exception object and its constructor in PythonError.pythonValue and PythonError.pythonType

Bug Fixes

  • Fix #27, a function as a single argument is considered a kwargs object
  • Fix #33, PyObject.prototype.constr has wrong TypeScript type

[1.2.0] 2022-11-25

New Features

  • Automatically proxified methods in pymport/proxified
  • Proxified objects also proxify the input arguments of passed JS callbacks
  • (BREAKING) Conversion of arguments in JS callbacks of Python code is now automatic only if it can be correctly deduced from the context, toJS() must be called in all other cases
  • Implement Python type coercion
  • Support Python sets

Bug Fixes

  • Fix #25, type-ahead provokes a crash in Node.js 14.x REPL

[1.1.1] 2022-11-11

  • Fix #14, toJS() converts Python bool to JS number
  • Restore the JS function when converting a pymport.js_function back to JS
  • Fix #17, PYTHONHOME is ignored
  • In the version reporting, replace the "undefined" suffix with a "" when there is no version suffix

[1.1.0] 2022-11-08

New Features

  • Converting JS functions to Python callables
  • Expiring of function objects
  • Converting of bytes and bytearray to Buffer and Buffer to bytearray
  • Converting between TypedArray and array
  • Convert Python iterators and generators to JavaScript Symbol.iterator
  • Basic tracking of the memory held by Python objects referenced in JS by the V8 GC
  • proxifyed object do not intercept and redirect calls to PyObject methods if the Python object has a method with the same name - ie. calling item() on a non-proxified PyObject invokes PyObject.item() but if the underlying Python object of a proxified object also has an item() function, calling item() on the proxified object will invoke the Python method
  • profixy always return the same reference if called with a previously seen PyObject reference
  • Support BigInt
  • PyObject.slice accepts named arguments
  • Return the Python traceback in pythonTrace and add a PythonError TypeScript type
  • Do not allow PYTHONPATH to override PYTHONHOME when using the builtin
  • Ignore the last argument of a Python function call if it is undefined - this allows to pass a last argument as a dictionary by calling fn(obj, undefined) instead of fn(obj) which will transform obj into named kw arguments
  • Support PyObject.keys and PyObject.values on profixyed objects
  • Support building against a prebuilt Python tree in a non-standard location
  • (internals) New automatic reference counting

Bug Fixes

  • Fix #6, proxified objects are wrongly caching values returned by getters
  • Fix #8, Infinity is not recognized as a float by the automatic conversion
  • Fix #11, npm install --build-from-source fails

[1.0.1] 2022-10-29

  • Enable TypeScript strict mode
  • Fix #1, always consume Python exceptions

[1.0.0] 2022-10-28

  • First release
