Scrapy core exceptions

These exceptions are documented in docs/topics/exceptions.rst. Please don't add new exceptions here without documenting them there.

Class ​Close​Spider Raise this from callbacks to request the spider to be closed
Class ​Contract​Fail Error raised in case of a failing contract
Class ​Dont​Close​Spider Request the spider not to be closed yet
Class ​Drop​Item Drop item from the item pipeline
Class ​Ignore​Request Indicates a decision was made not to process a request
Class ​Not​Configured Indicates a missing configuration situation
Class ​Not​Supported Indicates a feature or method is not supported
Class ​Stop​Download Stop the download of the body for a given response. The 'fail' boolean parameter indicates whether or not the resulting partial response should be handled by the request errback. Note that 'fail' is a keyword-only argument.
Class _​Invalid​Output Indicates an invalid value has been returned by a middleware's processing method. Internal and undocumented, it should not be raised or caught by user code.
Class ​Scrapy​Deprecation​Warning Warning category for deprecated features, since the default DeprecationWarning is silenced on Python 2.7+
Class ​Usage​Error To indicate a command-line usage error
