The New REPL Command History Does Not Honor Partial Text

Bug report

Bug description:

Let's say I fire up the REPL and start with the following:

>>> spam = 1
>>> ham = 2
>>> eggs = 3
>>> sp

At that point, I can up-arrow to scroll through my REPL command history. Normally with that partial sp on the line, hitting up-arrow once will immediately present spam = 1. Hitting it again will do nothing (since there are no more matching lines).

With the new REPL, it presents eggs = 3. Hitting it again will present ham = 2, and again it presents spam = 1. I'd rather it keep doing what it did before.

Inizia riproducendo il comportamento della cronologia con input parziale nella REPL del ramo principale di CPython su Linux, usando l’esempio sp del report. Confronta i risultati della freccia su con il comportamento previsto della cronologia filtrata per prefisso; il problema è risolto quando vengono mostrate solo le voci della cronologia corrispondenti e vengono saltate quelle non correlate.
