"this operation is only valid for push"

The sequence of calls

remote.ls_remotes(...)
remote.fetch(...)
remote.push(...)

works, while

remote.ls_remotes(...)
remote.push(...)

doesn't, producing the GIT_ERROR_NET / "this operation is only valid for push" error.

I think this is because ls_remotes() explicitly calls connect(..., GIT_DIRECTION_FETCH), and fetch() implicitly calls disconnect() (within git_remote_fetch()). If fetch() is not called between ls_remotes() and push(), git_remote_push() encounters an existing connection with FETCH direction, and returns an error (from git_smart__get_push_stream()).

This could be addressed in several ways: either by disconnecting explicitly in ls_remotes(), or maybe by changing the implementation of connect_or_reset_options() and the functions it calls to handle the case where direction is changing.

Commencez par reproduire les deux séquences d’appels avec remote.ls_remotes(), remote.fetch() et remote.push(), puis examinez connect_or_reset_options() et le chemin de git_remote_push() décrit dans l’issue. Le travail est terminé lorsque le push direct après ls_remotes() réussit sans l’erreur GIT_ERROR_NET, avec une couverture de régression pour cette séquence.
