What does this do? Especially the first command. Is this Windows specific?

Git specific. It means "remove every file and directory recursively
starting from the root of the repository". ``-r`` means recursive;
``:/`` is a "magic" git-specific path "root of the repo".

The second command checks out everything from the HEAD commit back to
the filesystem.

   Programmers don't die, they just GOSUB without RETURN.

That command causes a re-initialization of all of the files in the working 
copy. I got the recipe from here. 
There are more details in the comment I linked originally and the subsequent 
response.

Hi Jason,

One month ago, I changed the Buildbot configuration:
---
Use Git "fresh" method

Git "clean" method keeps most files created by a previous build. Use
Git "fresh" method instead to ignores .gitignore rules and so remove
all generated files (like ".o" files): run a fresh build rather than
an incremental build.

https://github.com/python/buildmaster-config/commit/f83c0a321dac8bb7d0df2e3098e7d36862f0b18a
https://github.com/python/buildmaster-config/pull/255
---

See https://docs.buildbot.net/latest/manual/configuration/steps/source_git.html
documentation.

I made this change to fix the following issue:
https://mail.python.org/archives/list/buildbot-sta...@python.org/thread/Z27NUT4OY7IGUNQXCTMO4GGSR7RWVB4J/

setup.py failed with: "RuntimeError: subprocess not supported for
isolated subinterpreters". It seems like aarch64 Fedora Rawhide 3.x
doesn't use a fresh build, but incremental build. I get such error
when I use incremental build.

Sorry, all! This post was pure spam - I clicked the wrong button on
