Description
An alternative implementation of what PyInstaller does, but with better control over the temporary extraction point and maybe better performance.
Like PyInstaller, single-binaries produced with Nuitka need to self-extract first. Default mode is to a timestamped, temporary location for every execution. This adds a large overhead to each command run. However, this location is configurable and can be set to a fixed location that gets cached. This is what we are doing with
--onefile-tempdir-spec={CACHE_DIR}/{COMPANY}/{PRODUCT}/{VERSION}. Only the first execution has an extraction overhead; following ones are instantaneous. This is a bit closer to what PyOxidizer promised :) Also a bit of thepyappconcepts.Nuitka is also easier to configure when it comes to traversing the imports. The entry point script serves both as the main code and the configuration file, btw.
Since Nuitka compiles the Python code, we don't have sources available, which makes
conda python -m ...syntax impossible to implement (runpy, which is what we used for this interface, wants source, not code objects).Checklist - did you ...
