python - How can I make scrapy crawl break and exit when encountering the first exception?

For development purposes, I would like to stop all scrapy crawling activity as soon a first exception (in a spider or a pipeline) occurs.

Any advice?

In spider, you can just throw CloseSpider exception.

def parse_page(self, response):
    if 'Bandwidth exceeded' in response.body:
        raise CloseSpider('bandwidth_exceeded')

For others (middlewares, pipeline, etc), you can manually call close_spider as akhter mentioned.
