Sema4AI Build Common

⚡️ sema4ai-build-common

A Python library containing common utilities for building Sema4AI projects.

-- it deals with things such as building and signing executables.

Notes on how it works:

• The sema4ai.build_common.workflows module contains the entry points that should be called by other projects.

• build_and_sign_executable should be called to actually build the executable and sign it.

• This function handles building and signing an executable, with these main steps:

  • Build: Uses PyInstaller to create an executable from Python code. It always builds in "not onefile" mode, meaning it creates a directory containing the executable and its dependencies.

  • Signing (Optional): If the sign parameter is True:

    • On macOS: Signs using macOS code signing and properly notarizes afterwards
    • On Windows: Signs using Windows code signing

  • Go Wrapper (Optional): If go_wrapper is True:

    • Zips the PyInstaller-built application assets
    • Builds a Go wrapper around the application
    • Creates a final executable that combines both
    • Signs the final executable if signing is enabled

• Requirements for build:

  • A <project-name>.spec file must be available in the root of the project with the pyinstaller spec to build the executable (the build process will use it to build with pyinstaller)

  • The go-wrapper for the app must also be in the root of the project (at this point, each app needs its own, although in the future a common base should probably be used). The build utilities will put a version.txt and an assets.zip in /go-wrapper/assets (if the /go-wrapper directory does not exist the build will fail).

Example of integration in sai-server -- note that sai-server uses typer to create a command line instead of invoke:

import typer

app = typer.Typer()

@app.command()
def build_executable(
    debug: bool = typer.Option(False, help="Build in debug mode"),
    ci: bool = typer.Option(
        True, help="Build in CI mode, disabling interactive prompts"
    ),
    dist_path: Path = typer.Option("dist", help="Path to the dist directory"),
    sign: bool = typer.Option(False, help="Sign the executable"),
    go_wrapper: bool = typer.Option(False, help="Build the Go wrapper too"),
    version: str | None = typer.Option(
        None, help="Version of the executable (gotten from github tag/pr if not passed)"
    ),
) -> None:
    """Build the project executable via PyInstaller."""
    from sema4ai.build_common.root_dir import get_root_dir
    from sema4ai.build_common.workflows import build_and_sign_executable

    from sema4ai.action_server import __version__

    if version is None:
        version = __version__  # Get version from the project...

    root_dir = get_root_dir()
    build_and_sign_executable(
        root_dir=root_dir,
        name="action-server",
        debug=debug,
        ci=ci,
        dist_path=root_dir / dist_path,
        sign=sign,
        go_wrapper=go_wrapper,
        version=__version__,
    )

The job that integrates it needs several environment variables for the signing and version gathering -- Note that the version is gotten from the tag or pr or branch name (based on the GITUB_EVENT_NAME, GITHUB_REF_NAME and GITHUB_PR_NUMBER), but applications that handle the version differently could pass the version in the command-line or call to build_and_sign_executable.
