  • Removed deprecated scrapy.xpath module - use scrapy.selector instead. (r1836)

  • Removed deprecated core.signals.domain_open signal - use core.signals.domain_opened instead (r1822)

  • log.msg() now receives a spider argument (r1822)
    • Old domain argument has been deprecated and will be removed in 0.9. For spiders, you should always use the spider argument and pass spider references. If you really want to pass a string, use the component argument instead.
  • Changed core signals domain_opened, domain_closed, domain_idle

  • Changed Item pipeline to use spiders instead of domains
    • The domain argument of process_item() item pipeline method was changed to spider, the new signature is: process_item(spider, item) (r1827 | #105)
    • To quickly port your code (to work with Scrapy 0.8) just use spider.domain_name where you previously used domain.
  • Changed Stats API to use spiders instead of domains (r1849 | #113)
    • StatsCollector was changed to receive spider references (instead of domains) in its methods (set_value, inc_value, etc).
    • added StatsCollector.iter_spider_stats() method
    • removed StatsCollector.list_domains() method
    • Also, Stats signals were renamed and now pass around spider references (instead of domains). Here’s a summary of the changes:
    • To quickly port your code (to work with Scrapy 0.8) just use spider.domain_name where you previously used domain. spider_stats contains exactly the same data as domain_stats.
  • CloseDomain extension moved to scrapy.contrib.closespider.CloseSpider (r1833)
    • Its settings were also renamed:
  • Removed deprecated SCRAPYSETTINGS_MODULE environment variable - use SCRAPY_SETTINGS_MODULE instead (r1840)



  • Refactored HTTP Cache middleware

  • HTTP Cache middleware has been heavilty refactored, retaining the same functionality except for the domain sectorization which was removed. (r1843 )

  • Renamed exception: DontCloseDomain to DontCloseSpider (r1859 | #120)

  • Renamed extension: DelayedCloseDomain to SpiderCloseDelay (r1861 | #121)

  • Removed obsolete scrapy.utils.markup.remove_escape_chars function - use scrapy.utils.markup.replace_escape_chars instead (r1865)
