From 1aa73658405ad423127b3c14ac13e46f9ad0163a Mon Sep 17 00:00:00 2001 From: Brandon Williams Date: Thu, 17 Nov 2016 10:46:03 -0800 Subject: push: --dry-run updates submodules when --recurse-submodules=on-demand This patch adds a test to illustrate how push run with --dry-run doesn't actually perform a dry-run when push is configured to push submodules on-demand. Instead all submodules which need to be pushed are actually pushed to their remotes while any updates for the superproject are performed as a dry-run. This is a bug and not the intended behaviour of a dry-run.

This is done by passing the --dry-run flag to the child process which performs a push for a submodules when performing a dry-run. In order to preserve good user experience, the additional check for unpushed submodules is skipped during a dry-run when --recurse-submodules=on-demand. The check is skipped because the submodule pushes were performed as dry-runs and this check would always fail as the submodules would still need to be pushed.
