"""Update the submodules of this repository to the current HEAD commit.
|
|
This method behaves smartly by determining changes of the path of a submodules
|
|
repository, next to changes to the to-be-checked-out commit or the branch to be
|
|
checked out. This works if the submodules ID does not change.
|
|
Additionally it will detect addition and removal of submodules, which will be handled
|
|
gracefully.
|
|
|
|
:param previous_commit: If set to a commit'ish, the commit we should use
|
|
as the previous commit the HEAD pointed to before it was set to the commit it points to now.
|
|
If None, it defaults to HEAD@{1} otherwise
|
|
:param recursive: if True, the children of submodules will be updated as well
|
|
using the same technique
|
|
:param force_remove: If submodules have been deleted, they will be forcibly removed.
|
|
Otherwise the update may fail if a submodule's repository cannot be deleted as
|
|
changes have been made to it (see Submodule.update() for more information)
|
|
:param init: If we encounter a new module which would need to be initialized, then do it.
|
|
:param to_latest_revision: If True, instead of checking out the revision pointed to
|
|
by this submodule's sha, the checked out tracking branch will be merged with the
|
|
latest remote branch fetched from the repository's origin.
|
|
Unless force_reset is specified, a local tracking branch will never be reset into its past, therefore
|
|
the remote branch must be in the future for this to have an effect.
|
|
:param force_reset: if True, submodules may checkout or reset their branch even if the repository has
|
|
pending changes that would be overwritten, or if the local tracking branch is in the future of the
|
|
remote tracking branch and would be reset into its past.
|
|
:param progress: RootUpdateProgress instance or None if no progress should be sent
|
|
:param dry_run: if True, operations will not actually be performed. Progress messages
|
|
will change accordingly to indicate the WOULD DO state of the operation.
|
|
:param keep_going: if True, we will ignore but log all errors, and keep going recursively.
|
|
Unless dry_run is set as well, keep_going could cause subsequent/inherited errors you wouldn't see
|
|
otherwise.
|
|
In conjunction with dry_run, it can be useful to anticipate all errors when updating submodules
