Log message:
python: egg.mk: add USE_PKG_RESOURCES flag

This flag should be set for packages that import pkg_resources
and thus need setuptools after the build step.

Set this flag for packages that need it and bump PKGREVISION.

Log message:
*: bump PKGREVISION for egg.mk users

They now have a tool dependency on py-setuptools instead of a DEPENDS

Log message:
py-scrapy: updated to 1.7.3

Scrapy 1.7.3:
Enforce lxml 4.3.5 or lower for Python 3.4 (issue 3912, issue 3918).

Scrapy 1.7.2:
Fix Python 2 support (issue 3889, issue 3893, issue 3896).

Scrapy 1.7.1:
Re-packaging of Scrapy 1.7.0, which was missing some changes in PyPI.

Scrapy 1.7.0:
Highlights:
Improvements for crawls targeting multiple domains
A cleaner way to pass arguments to callbacks
A new class for JSON requests
Improvements for rule-based spiders
New features for feed exports

Backward-incompatible changes

429 is now part of the RETRY_HTTP_CODES setting by default
This change is backward incompatible. If you don’t want to retry 429, you must \ 
override RETRY_HTTP_CODES accordingly.

Crawler, CrawlerRunner.crawl and CrawlerRunner.create_crawler no longer accept a \ 
Spider subclass instance, they only accept a Spider subclass now.
Spider subclass instances were never meant to work, and they were not working as \ 
one would expect: instead of using the passed Spider subclass instance, their \ 
from_crawler method was called to generate a new instance.

Non-default values for the SCHEDULER_PRIORITY_QUEUE setting may stop working. \ 
Scheduler priority queue classes now need to handle Request objects instead of \ 
arbitrary Python data structures.

New features

A new scheduler priority queue, scrapy.pqueues.DownloaderAwarePriorityQueue, may \ 
be enabled for a significant scheduling improvement on crawls targetting \ 
multiple web domains, at the cost of no CONCURRENT_REQUESTS_PER_IP support \ 
(issue 3520)
A new Request.cb_kwargs attribute provides a cleaner way to pass keyword \ 
arguments to callback methods (issue 1138, issue 3563)
A new JSONRequest class offers a more convenient way to build JSON requests \ 
(issue 3504, issue 3505)
A process_request callback passed to the Rule constructor now receives the \ 
Response object that originated the request as its second argument (issue 3682)
A new restrict_text parameter for the LinkExtractor constructor allows filtering \ 
links by linking text (issue 3622, issue 3635)
A new FEED_STORAGE_S3_ACL setting allows defining a custom ACL for feeds \ 
exported to Amazon S3 (issue 3607)
A new FEED_STORAGE_FTP_ACTIVE setting allows using FTP’s active connection \ 
mode for feeds exported to FTP servers (issue 3829)
A new METAREFRESH_IGNORE_TAGS setting allows overriding which HTML tags are \ 
ignored when searching a response for HTML meta tags that trigger a redirect \ 
(issue 1422, issue 3768)
A new redirect_reasons request meta key exposes the reason (status code, meta \ 
refresh) behind every followed redirect (issue 3581, issue 3687)
The SCRAPY_CHECK variable is now set to the true string during runs of the check \ 
command, which allows detecting contract check runs from code (issue 3704, issue \ 
3739)
A new Item.deepcopy() method makes it easier to deep-copy items (issue 1493, \ 
issue 3671)
CoreStats also logs elapsed_time_seconds now (issue 3638)
Exceptions from ItemLoader input and output processors are now more verbose \ 
(issue 3836, issue 3840)
Crawler, CrawlerRunner.crawl and CrawlerRunner.create_crawler now fail \ 
gracefully if they receive a Spider subclass instance instead of the subclass \ 
itself (issue 2283, issue 3610, issue 3872)

Bug fixes

process_spider_exception() is now also invoked for generators (issue 220, issue 2061)
System exceptions like KeyboardInterrupt are no longer caught (issue 3726)
ItemLoader.load_item() no longer makes later calls to \ 
ItemLoader.get_output_value() or ItemLoader.load_item() return empty data (issue \ 
3804, issue 3819)
The images pipeline (ImagesPipeline) no longer ignores these Amazon S3 settings: \ 
AWS_ENDPOINT_URL, AWS_REGION_NAME, AWS_USE_SSL, AWS_VERIFY (issue 3625)
Fixed a memory leak in MediaPipeline affecting, for example, non-200 responses \ 
and exceptions from custom middlewares (issue 3813)
Requests with private callbacks are now correctly unserialized from disk (issue 3790)
FormRequest.from_response() now handles invalid methods like major web browsers

Log message:
py-scrapy: updated to 1.6.0

Scrapy 1.6.0:

Highlights:
* better Windows support;
* Python 3.7 compatibility;
* big documentation improvements, including a switch
  from .extract_first() + .extract() API to .get() + .getall()
  API;
* feed exports, FilePipeline and MediaPipeline improvements;
* better extensibility: :signal:item_error and
  :signal:request_reached_downloader signals; from_crawler support
  for feed exporters, feed storages and dupefilters.
* scrapy.contracts fixes and new features;
* telnet console security improvements, first released as a
  backport in :ref:release-1.5.2;
* clean-up of the deprecated code;
* various bug fixes, small new features and usability improvements across
  the codebase.

Log message:
py-scrapy: updated to 1.5.2

Scrapy 1.5.2:

* *Security bugfix*: Telnet console extension can be easily exploited by rogue
  websites POSTing content to http://localhost:6023, we haven't found a way to
  exploit it from Scrapy, but it is very easy to trick a browser to do so and
  elevates the risk for local development environment.

  *The fix is backwards incompatible*, it enables telnet user-password
  authentication by default with a random generated password. If you can't
  upgrade right away, please consider setting :setting:TELNET_CONSOLE_PORT
  out of its default value.

  See :ref:telnet console <topics-telnetconsole> documentation for more info

* Backport CI build failure under GCE environemnt due to boto import error.
