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?

Comienza con la documentación de commit_log en https://www.pygit2.org/commit_log.html y la descripción de Repository.walk(). Aclara cómo se obtiene y se usa un Walker, incluido si la iteración conserva los commits visitados entre llamadas repetidas a push. Se considera terminado cuando la página responde al comportamiento del ejemplo sin que los lectores tengan que inferirlo.
