Walker?

https://www.pygit2.org/commit_log.html describes a Walker object, but does not explain how to get one or how to use it. Are we to infer that the the iterator produced by the call to Repository.walk() immediately above is an object of type Walker? When I debug that seems to be the case.

For example, if heads is a list of heads and w a Walker, will

for h in heads:
    w.push(h)
    for cmt in w:
        do_stuff(cmt)

call do_stuff exactly once (i.e., the walker remembers and ignores commits already visited on later calls) for each commit in my repository that is reachable from any head?

Inizia dalla documentazione di commit_log all’indirizzo https://www.pygit2.org/commit_log.html e dalla descrizione di Repository.walk(). Chiarisci come si ottiene e si utilizza un Walker, incluso se l’iterazione conserva i commit visitati tra chiamate ripetute a push. Il lavoro è completato quando la pagina chiarisce il comportamento dell’esempio senza richiedere ai lettori di dedurlo.
