I have cloned the Python source repo, and build CPython, as described here:
https://docs.python.org/devguide/ Now a little bit later, I want to update the repo, so I run: hg fetch to get and apply any changes. How do I know if I need to rebuild Python? I don't want to have to rebuild after every fetch, because that's quite time consuming (I estimate about five minutes on my machine, just long enough to be a distraction but not long enough to get into something else). Plus the time to run the tests (significantly longer). What do others do? -- Steve “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse. -- https://mail.python.org/mailman/listinfo/python-list
