Commands changes:
* removed (somewhat hacky) --init argument from settings command
* added set_crawler method to Commands, and a ``crawler`` property that returns
a configured crawler. This way, commands that don't require a crawler (such
as startproject) won't need to configure one.
Execution Queue changes:
* changed SERVICE_QUEUE_FILE setting to SQLITE_DB
* removed SERVICE_QUEUE setting
* added QUEUE_CLASS setting for defining the class to use for the execution queue
* added SERVER_QUEUE_CLASS setting for defining the class to use for the
execution queue in server mode (runserver command)
Spider Manager changes:
* simplified SpiderManager API by removing the load() method
* added from_settings classmethod to SpiderManager
* added spider_modules constructor argument to SpiderManager
Crawler changes:
* added install() method to Crawler (to install it in scrapy.project) and
uninstall() to remove it
* use CrawlerProcess.install() in scrapy.cmdline
* use crawler.install() and crawler.uninstall() in tests that a crawler in
scrapy.project
* make telnet console and webservice play nicer with twisted by stopping
listening when then engine goes down
* refactored Scrapy engine tests - it no longer uses the crawler singleton.
Closes#215.
into this class and leaving the Crawler class free of any reactor control.
This allows embedding the Scrapy crawler in other Twisted applications, or any
Twisted asynchronous code.
The "scrapy" command will use the new CrawlerProcess class, which resembles the
behaviour of the old (all-in-one) Crawler class.
Closes#214.
Also moved log.start() call from Crawler class to scrapy.cmdline module.
Detail of changes:
* Moved scrapy.core.manager.ExecutionManager class to scrapy.crawler.Crawler
* Added scrapy.project.crawler singleton to reference a singleton instance of
Crawler class (previously known as scrapymanager)
* Left an alias scrapy.core.manager.scrapymanager to scrapy.project.crawler for
backwards compatibility (to be removed in Scrapy 0.11)
* moved scrapy.stats.collector.__init__ module to scrapy.statscol
* moved scrapy.stats.collector.simpledb module to scrapy.contrib.statscol
* moved signals from scrapy.stats.signals to scrapy.signals
* moved scrapy/stats/__init__.py to scrapy/stats.py
