end

#set_repository_read_only!(skip_git_transfer_check: false) ⇒ Object

Tries to set repository as read_only, checking for existing Git transfers in progress beforehand. Setting a repository read-only will fail if it is already in that state.

It is assumed that with_lock is used here to ensure that no race condition appears between reading and writing the read-only column.

Returns:

  • nil. Failures will raise an exception

def set_repository_read_only!(skip_git_transfer_check: false)
  with_lock do
    raise RepositoryReadOnlyError, _('Git transfer in progress') if
      !skip_git_transfer_check && git_transfer_in_progress?

    raise RepositoryReadOnlyError, _('Repository already read-only') if
      safe_read_repository_read_only_column

    raise ActiveRecord::RecordNotSaved, _('Database update failed') unless
      update_repository_read_only_column(true)

    nil
  end
end

#set_repository_writable! ⇒ Object

Set repository as writable again. Unlike setting it read-only, this will succeed if the repository is already writable.

Raises:

  • (ActiveRecord::RecordNotSaved)
