Reproducible Builds for macOS

There's a neat writeup I stumbled across recently titled "Reproducible codesigning on Apple Silicon" from Keith Smiley about some gotchas when it comes to compiling a binary in a way that's repeatable and always generates the exact same byte output (which would then checksum to the exact same hash) - even if compiled on a different Mac.

In applying the suggestions I found in the blog post, I found a few other corner cases that I just wanted to get documented more explicitly somewhere.

Tools Matter

Footnote 2 from that blog post is important:

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

OBSOLETE

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.

from functools import wraps, partial

class memoize(object):
    """cache the return value of a method

    This class is meant to be used as a decorator of methods. The return value
    from a given method invocation will be cached on the instance whose method
    was invoked. All arguments passed to a method decorated with memoize must
    be hashable.

# Update 7 Oct 2010:
# - This example does *not* appear to work with Chrome >=6.0. Apparently,
#   the WebSocket protocol implementation in the cramp gem does not work
#   well with Chrome's (newer) WebSocket implementation.

# Requirements:
# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby
