Release notes

1.0 (2015-06-19)

You will find a lot of new features and bugfixes in this major release. Make sure to check our updated overview <intro-overview> to get a glance of some of the changes, along with our brushed tutorial <intro-tutorial>.

Support for returning dictionaries in spiders

Declaring and returning Scrapy Items is no longer necessary to collect the scraped data from your spider, you can now return explicit dictionaries instead.

Classic version

class MyItem(scrapy.Item):
    url = scrapy.Field()

class MySpider(scrapy.Spider):
    def parse(self, response):
        return MyItem(url=response.url)

New version

class MySpider(scrapy.Spider):
    def parse(self, response):
        return {'url': response.url}

Per-spider settings (GSoC 2014)

Last Google Summer of Code project accomplished an important redesign of the mechanism used for populating settings, introducing explicit priorities to override any given setting. As an extension of that goal, we included a new level of priority for settings that act exclusively for a single spider, allowing them to redefine project settings.

Start using it by defining a ~scrapy.spiders.Spider.custom_settings class variable in your spider:

class MySpider(scrapy.Spider):
    custom_settings = {
        "DOWNLOAD_DELAY": 5.0,
        "RETRY_ENABLED": False,
    }

Read more about settings population: topics-settings

Python Logging

Scrapy 1.0 has moved away from Twisted logging to support Python built in’s as default logging system. We’re maintaining backward compatibility for most of the old custom interface to call logging functions, but you’ll get warnings to switch to the Python logging API entirely.

Old version

from scrapy import log
log.msg('MESSAGE', log.INFO)

New version

import logging
logging.info('MESSAGE')

Logging with spiders remains the same, but on top of the ~scrapy.spiders.Spider.log method you’ll have access to a custom ~scrapy.spiders.Spider.logger created for the spider to issue log events:

class MySpider(scrapy.Spider):
    def parse(self, response):
        self.logger.info('Response received')

Read more in the logging documentation: topics-logging

Crawler API refactoring (GSoC 2014)

Another milestone for last Google Summer of Code was a refactoring of the internal API, seeking a simpler and easier usage. Check new core interface in: topics-api

A common situation where you will face these changes is while running Scrapy from scripts. Here’s a quick example of how to run a Spider manually with the new API:

from scrapy.crawler import CrawlerProcess

process = CrawlerProcess({
    'USER_AGENT': 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)'
})
process.crawl(MySpider)
process.start()

Bear in mind this feature is still under development and its API may change until it reaches a stable status.

See more examples for scripts running Scrapy: topics-practices

Module Relocations

There’s been a large rearrangement of modules trying to improve the general structure of Scrapy. Main changes were separating various subpackages into new projects and dissolving both scrapy.contrib and scrapy.contrib_exp into top level packages. Backward compatibility was kept among internal relocations, while importing deprecated modules expect warnings indicating their new place.

These extensions went through some minor changes, e.g. some setting names were changed. Please check the documentation in each new repository to get familiar with the new usage.
