The Example in the readline documentation (section 6.7 of the Library Reference) shows how to save your readline history in a file, and restore it each time you start Python.
The problem with the Example is that it does not include a call to readline.set_history_length and the default is -1 (infinite).
As a Python developer, I start Python quite a lot and had a .python_history file that was 850M bytes. Just starting Python was causing my system to thrash before the first prompt (>>>) even appeared.
I suggest adding the following line to the example to avoid this:
readline.set_history_length(1000)
I'm not sure how far back this goes in terms of earlier versions of Python, but probably quite far. |
