v0.14.0

Python support

• Drop Python 3.9 support.

Added

• Add an inject command.

  This allows a database of dependencies to be injected into a target file.
  This can be used to make a Python file a standalone executable.

  This feature requires Python 3.11 and higher at execution time
  due to sqlite3 API usage.

Documentation

• Use pngcrush to make image file sizes smaller.

• Link to the source code repository without using an iframe.

• Document how to import sqliteimport and load a database of packages.

  This now includes runnable scripts showing fully-automated loading
  using sitecustomize.py and the PYTHONPATH environment variable.
  In addition, more information is provided
  for manually importing sqliteimport and loading a database.

Development

• Migrate the flake8 configuration to pyproject.toml using
  the flake8-toml-config plugin.
• Test type annotations against all supported Python versions.
• Lock the GitHub CI runners to known, predictable versions.
• Lock the coverage dependencies used for generating HTML reports
  to match the same version used to gather coverage statistics.

v0.13.0

Python support

• Drop support for PyPy 3.10.

Fixed

• Fall back to importing from source code if importing from byte code fails.

  This resolves a problem importing Flask when byte-compiled,
  due to its sansio subdirectory, which has no __init__.py file
  and whose submodules currently fail to import from the byte code table.

Documentation

• Document compatible ruff configurations.

• Add a logo and description to the sidebar on subpages.

• Update the homepage sidebar layout and design.

Development

• Fix performance testing issues.

  Zip-based bytecode import times were skewed during testing
  because zipimport doesn't use PEP 3147 __pycache__/ subdirectories.
  This is now accounted for by the performance testing script's setup steps,
  and zip-based import times are now accurate for comparison.

  Also, the total size of the source code and byte code trees is captured.

• Begin to expand and better automate performance testing.

  This includes the ability to install from a requirements.txt file,
  to execute an arbitrary Python file, and to plot comparison bar charts
  of import times and package content sizes.

• Use chipshot to standardize headers.

• Prefer the new Python 3.14 compression.lzma namespace.

v0.12.0

Fixed

• Find all available distributions when no name is given.

  This allows tools like flake8 to auto-detect installed plugins.

v0.11.0

Fixed

• Fix a crash that occurs when CLI extras are not installed.

  This restores the user-friendly warning message behavior
  when [cli] extras are not installed.

Changed

• A FileNotFoundError subclass is now raised when a file isn't found.

  Previously, a TypeError was implicitly raised due to the structure of the code.

Documentation

• Add a CITATION.cff file.

v0.10.0

Added

• Add preliminary support for displaying files and source lines in tracebacks.

v0.9.0

Fixed

• Ensure that modules have a __file__ attribute,
  and possibly a __cached__ attribute.

  The Python data model docs make it clear that these attributes aren't guaranteed,
  but it is nevertheless common for authors to assume that __file__ exists.

  The string value may not be usable for a specific purpose,
  but the attributes now exist with the correct type for increased compatibility.

v0.8.0

Added

• Support namespace packages.

Fixed

• Fix a bug, and inconsistencies, in the describe command output.
• Verify a distribution package exists in the database before claiming it does.

v0.7.0

Added

• Add a subcommand, describe, to print info about a database.
• Add an alias for the CLI sqliteimport command: si.

Development

• Improve the isolation of compatibility code.

v0.6.0

Added

• Compress all database content using the LZMA algorithm.

  sqliteimport now produces databases that are smaller than importable zip files.

• Support compiling to, and loading from, pre-compiled bytecode in the database.

  Performance testing shows that sqliteimport now imports large dependency trees
  faster than standard filesystem-based imports.

• Add a sqliteimport compile command to compile all Python source to bytecode.

  The command should be run for each Python interpreter that will be used
  by the application.

Development

• Add a Powershell script to test performance on Windows.

v0.5.0

Python support

• Support PyPy 3.11.

Added

• Add initial support for bundling and loading Python bytecode (.pyc files).

  Performance testing on Linux shows that loading from sqlite is now twice as fast.

  The implementation is currently inflexible:
  it binds the sqlite database to the Python version used to bundle it.

Documentation

• Add the changelog and a colophon to the documentation.
• Configure ReadtheDocs to use the dirhtml builder.
• Update the links shown on PyPI.

Development

• Fix test project regeneration, which broke when Poetry 2 was released.

  • Migrate from Poetry to build to build the test project wheels.
  • Pin the regeneration tool dependencies.
  • Update the test projects' pyproject.toml files to use PEP 621 metadata keys.

• Add a script to log performance comparisons across multiple importers,
  including source and bytecode files when imported from the filesystem,
  from sqlite, and from zip files with varying compression levels.
