CSS selectors

I'm a web developer and designer turned into a web scraper. Python is easy and I love it. Scrapy is wonderful. But XPath... it's a foreign language that mostly does what CSS selectors do — but those are second language to me. Anyone coming from jQuery or CSS will already be used to CSS selectors.

So I decided to improve scrapy to support CSS selectors, using the cssselect package that got extracted from the lxml package. I've created two Selector classes, HtmlCSSSelector and XmlCSSSelector, that basically translate the CSS selectors into XPath selectors and run the parent class select method. Easy Peasy.

I'm looking into how to provide tests for these new classes, but would love some guidance. This is my first contribution to a Python package.

Scrapy.selector Enhancement Proposal

Make scrapy.selector into a separate project.

When we're scraping web pages, the most common task you need to perform is to extract data from the HTML source. There are several libraries available to achieve this: BeautifulSoup, lxml. And although scrapy selectors are built over the lxml library, it is a better way to extract data from HTML source. In my opinion, people will prefer selector to BeautifulSoup and lxml , if make the scrapy.selectors into a separate project,

New selector method: extract_first()
I think about suggestion to improve scrapy Selector. I've seen this construction in many projects:

result = sel.xpath('//div/text()').extract()[0]

And what about if result: and else:, or try: and except:, which should be always there? When we don't want ItemLoaders, the most common use of selector is retrieving only single element. Maybe there should be method xpath1 or xpath_one or xpath_first that returns first matched element or None?

[GSoC 2019] Support for Different robots.txt Parsers
This issue is a single place for all students and mentors to discuss ideas and proposals for Support for Different robots.txt Parsers GSoC project. First of all, every student involved should have not very big contribution to https://github.com/scrapy/scrapy project. It should not be very big, just to get your hands dirty and get accustomed to processes and tools. Contribution should be done in a form of open Pull Request to solve a problem not related to robots.txt project. You can read open issues or open PRs and choose one for yourself. Or you can ask here and mentors and contributors will some recommendations.

Problems for current robots.txt implementation can be traced in relevant issues:

Issue with running scrapy spider from script.

Hi, I'm trying to run scrapy from a script like this:

import scrapy
from scrapy.crawler import CrawlerProcess

class MySpider(scrapy.Spider):
    name = "basic"
    allowed_domains = ["web"]
    start_urls = ['http://www.example.com']

    def parse(self, response):
        l = ItemLoader(item=PropertiesItem(), response = response)
        l.add_xpath('title', '//h1[1]/text()')

        return l.load_item()
process = CrawlerProcess({
    'USER_AGENT': 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)'
})

process.crawl(MySpider)
process.start()

However, when I run this script I get the following error:

File "/Library/Python/2.7/site-packages/Twisted-16.7.0rc1-py2.7-macosx-10.11-
intel.egg/twisted/internet/_sslverify.py", line 38, in <module>
TLSVersion.TLSv1_1: SSL.OP_NO_TLSv1_1,
AttributeError: 'module' object has no attribute 'OP_NO_TLSv1_1'

Does anyone know how to fix this? Thanks in advance.

Centralized Request fingerprints
It is very easy to have a subtle bug when using a custom duplicates filter that changes how request fingerprint is calculated.

Duplicate filter checks request fingerprint and makes Scheduler drop the request if it is a duplicate.

Cache storage checks request fingerprint and fetches response from cache if it is a duplicate.

If fingerprint algorithms differ we're in trouble.

The problem is that there is no way to override request fingerprint globally; to make Scrapy always take something extra in account (an http header, a meta option) user must override duplicates filter and all cache storages that are in use.

Ideas about how to fix it:

Use duplicates filter request_fingerprint method in cache storage if this method is available;

create a special Request.meta key that request_fingerprint function will take into account;

create a special Request.meta key that will allow to provide a pre-calculated fingerprint;

add a settings.py option to override request fingerprint function globally.

Support relative urls better

Building an URL relative to current URL is a very common task; currently users are required to do that themselves - import urlparse and then urlparse.urljoin(response.url, href).

What do you think about adding a shortcut for that - something like response.urljoin(href) or response.absolute_url(href)?

Another crazy idea is to support relative urls directly, by assuming they are relative to a response.url. I think it can be implemented as a spider middleware. I actually like this idea :)

sslv3 alert handshake failure when making a request

Hi there, I recently upgraded to the latest scrapy and on some sites SSL enabled sites I get an exception when trying to make requests to it, while on previous scrapy versions I didn't have this issue. The issue can be seen by making a request with scrapy shell:

scrapy shell "https://www.gohastings.com/"

The error I get is: Retrying <GET https://www.gohastings.com/> (failed 1 times): <twisted.python.failure.Failure OpenSSL.SSL.Error: ('SSL routines', 'SSL3_READ_BYTES', 'sslv3 alert handshake failure'), ('SSL routines', 'SSL3_WRITE_BYTES', 'ssl handshake failure')>

GSoC 2021: Feeds enhancements
This is a single issue to discuss feeds enhancements as a project for GSoC 2021.

My idea here is to make a project to work on 3 (or more) improvements detailed below.

1 - filter items on export based on custom rules.

Relevant issues:

https://github.com/scrapy/scrapy/issues/4607

https://github.com/scrapy/scrapy/issues/4575

https://github.com/scrapy/scrapy/issues/4786

https://github.com/scrapy/scrapy/issues/3193

There is already a PR for this one (note my last comment there) https://github.com/scrapy/scrapy/pull/4576

However, if the author doesn't reply on time, we can continue the work from the branch and only finish the feature.

2 - Compress feeds

This is an old feature request and there's an issue for it here https://github.com/scrapy/scrapy/issues/2174 The API changed a bit since then, but I think it'd be something like

FEEDS = { "myfile.jl": { "compression": "gzip" } }

I think gzip is a good starting point, but we should put some effort to design an API that will be extensible and allow different formats.

3 - Spider open/close a batch

Recently we added support for batch delivery in scapy. Say, every X items, we deliver a file and open a new file. Sometimes, we don't know the threshold upfront or it can be based on an external signal. In this case, we should be able to trigger a batch delivery from the spider. I have two possible ideas for it:

Create a new signal: scrapy.signals.close_batch

Add a method that can be called from the spider spider.feed_exporter.close_batch()

Note that, this can be tricky as we allow multiple feeds (so it may require an argument specifying which feed batch to close).

AsyncioTest failures

There are two new failing tests (AsyncioTest.test_install_asyncio_reactor and AsyncioTest.test_is_asyncio_reactor_installed) on 3.10 and 3.11, and it looks like they started failing after updating to 3.10.9 and 3.11.1 (it may be a coincidence though). I see an asyncio-related change in those versions: "asyncio.get_event_loop() now only emits a deprecation warning when a new event loop was created implicitly. It no longer emits a deprecation warning if the current event loop was set." and it looks like it's the cause for the test_install_asyncio_reactor failure as that checks for a warning and maybe there is some new warning. But the second test is about installing the reactor and checking its type and the failure looks like the asyncio reactor is installed when it shouldn't.

Finish exporting for each start exporting
Figured I'd take a crack at #5537 since it's been stale for a while.

This patch moves the call to slot.finish_exporting() up to before the conditional that checks if slot.item_count > 0 so that if an exception occurs when an exporter's export_item() method is called, slot.finish_exporting() will still be called (as discussed in the issue).

I've included 4 new tests to that each check that:

if slot.start_exporting() was called that there is a call to slot.finish_exporting() after

slot.finish_exporting() is not called before a call to slot.start_exporting(). I.e. they assert that slot.finish_exporting() isn't called twice in a row without a call to slot.start_exporting() in between and that slot.finish_exporting() isn't called before an initial call to slot.start_exporting.

test_start_finish_exporting_items_exception fails before the patch and passes after the patch. The other 3 tests pass before and after.

Security bug fixes

When a Request object with cookies defined gets a redirect response causing a new Request object to be scheduled, the cookies defined in the original Request object are no longer copied into the new Request object.

If you manually set the Cookie header on a Request object and the domain name of the redirect URL is not an exact match for the domain of the URL of the original Request object, your Cookie header is now dropped from the new Request object.

The old behavior could be exploited by an attacker to gain access to your cookies. Please, see the cjvr-mfj7-j4j8 security advisory for more information.

Note: It is still possible to enable the sharing of cookies between different domains with a shared domain suffix (e.g. example.com and any subdomain) by defining the shared domain suffix (e.g. example.com) as the cookie domain when defining your cookies. See the documentation of the Request class for more information.

When the domain of a cookie, either received in the Set-Cookie header of a response or defined in a Request object, is set to a public suffix <https://publicsuffix.org/>_, the cookie is now ignored unless the cookie domain is the same as the request domain.

The old behavior could be exploited by an attacker to inject cookies from a controlled domain into your cookiejar that could be sent to other domains not controlled by the attacker. Please, see the mfjm-vh54-3f96 security advisory for more information.

2.5.1(Oct 5, 2021)

Security bug fix:

If you use HttpAuthMiddleware (i.e. the http_user and http_pass spider attributes) for HTTP authentication, any request exposes your credentials to the request target.

To prevent unintended exposure of authentication credentials to unintended domains, you must now additionally set a new, additional spider attribute, http_auth_domain, and point it to the specific domain to which the authentication credentials must be sent.

If the http_auth_domain spider attribute is not set, the domain of the first request will be considered the HTTP authentication target, and authentication credentials will only be sent in requests targeting that domain.

If you need to send the same HTTP authentication credentials to multiple domains, you can use w3lib.http.basic_auth_header instead to set the value of the Authorization header of your requests.

If you really want your spider to send the same HTTP authentication credentials to any domain, set the http_auth_domain spider attribute to None.

Finally, if you are a user of scrapy-splash, know that this version of Scrapy breaks compatibility with scrapy-splash 0.7.2 and earlier. You will need to upgrade scrapy-splash to a greater version for it to continue to work.

1.2.1(Dec 8, 2016)
Bug fixes

Include OpenSSL’s more permissive default ciphers when establishing TLS/SSL connections (#2314).

1.2.0(Oct 3, 2016)
New Features

New FEED_EXPORT_ENCODING setting to customize the encoding used when writing items to a file. This can be used to turn off \uXXXX escapes in JSON output. This is also useful for those wanting something else than UTF-8 for XML or CSV output (#2034).

startproject command now supports an optional destination directory to override the default one based on the project name (#2005).

New SCHEDULER_DEBUG setting to log requests serialization failures (#1610).

JSON encoder now supports serialization of set instances (#2058).

Interpret application/json-amazonui-streaming as TextResponse (#1503).

scrapy is imported by default when using shell tools (shell, inspect_response) (#2248).

Bug fixes

DefaultRequestHeaders middleware now runs before UserAgent middleware (#2088). Warning: this is technically backwards incompatible, though we consider this a bug fix.

HTTP cache extension and plugins that use the .scrapy data directory now work outside projects (#1581). Warning: this is technically backwards incompatible, though we consider this a bug fix.

Selector does not allow passing both response and text anymore (#2153).

Fixed logging of wrong callback name with scrapy parse (#2169).

Fix for an odd gzip decompression bug (#1606).

Fix for selected callbacks when using CrawlSpider with scrapy parse (#2225).

Fix for invalid JSON and XML files when spider yields no items (#872).

Implement flush() for StreamLogger avoiding a warning in logs (#2125).

Refactoring

canonicalize_url has been moved to w3lib.url (#2168).

Tests & Requirements

Scrapy's new requirements baseline is Debian 8 "Jessie". It was previously Ubuntu 12.04 Precise. What this means in practice is that we run continuous integration tests with these (main) packages versions at a minimum: Twisted 14.0, pyOpenSSL 0.14, lxml 3.4.

Scrapy may very well work with older versions of these packages (the code base still has switches for older Twisted versions for example) but it is not guaranteed (because it's not tested anymore).

Documentation

Grammar fixes: #2128, #1566.

Download stats badge removed from README (#2160).

New scrapy architecture diagram (#2165).

Updated Response parameters documentation (#2197).

Reworded misleading RANDOMIZE_DOWNLOAD_DELAY description (#2190).

Add StackOverflow as a support channel (#2257).
