Mercurial API push bookmark

[PIERRE AUGIER]

Hi,

I try to run something like `hg push git+ssh://git@github.com/fluiddyn/fluiddyn -B master` in a Mercurial extension.

Please can anyone explain why it does not work with

commands.push(ui, repo, dest=path_github, bookmark="master")

whereas it works well with

subprocess.call(["hg", "push", path_github, "-B", "master"])

???
