Cleanup other directories in .shiv

I’d like to be able to have a shiv option that would instruct the bootstrap code to clean out old directories in .shiv for the current app. Maybe:

shiv --delete-other-builds

With that option, when the first bootstrap of a build finished, the boostrap code would essentially run:

rm -rf ~/.shiv/the_app_name_*

Excluding the folder that contains the files for the currently running app.

@luislew that’s awesome to hear! say hi to @borgstrom for me 😃

I went ahead and cut a PR with this feature, take it for a spin and let me know what you think 😃

Hey @rsyring, sorry that it’s taken me literal months to revisit this issue, but I think the --preamble idea I posed earlier will satisfy this request, take a look at my diff https://github.com/linkedin/shiv/compare/preamble?expand=1

I included an example script that cleans up old execution dirs:

(venv) darwin ~/src/shiv $ cat hello.py 
#!/usr/bin/env python3

import shutil

current = site_packages.parent
cache_path = current.parent
name, build_id = current.name.split('_')

if __name__ == "__main__":
    for path in cache_path.iterdir():
        if path.name.startswith(f"{name}_") and not path.name.endswith(build_id):
            print(f"deleting {path}")
            shutil.rmtree(path)

(venv) darwin ~/src/shiv git:preamble ± $ shiv -c http httpie setuptools --preamble hello.py -o http.pyz -q
(venv) darwin ~/src/shiv git:preamble ± $ ./http.pyz

Theoretically you could even pack another pyz into the pyz (though I haven’t tested this). Let me know what you think, if it works for you I will add some tests and cut a PR.
