2499899554 [mod] Google: reversed engineered & upgrade to data_type: traits_v1
Partial reverse engineering of the Google engines including a improved language
and region handling based on the engine.traits_v1 data.

When ever possible the implementations of the Google engines try to make use of
the async REST APIs.  The get_lang_info() has been generalized to a
get_google_info() function / especially the region handling has been improved by
adding the cr parameter.

searx/data/engine_traits.json
  Add data type "traits_v1" generated by the fetch_traits() functions from:

  - Google (WEB),
  - Google images,
  - Google news,
  - Google scholar and
  - Google videos

  and remove data from obsolete data type "supported_languages".

  A traits.custom type that maps region codes to *supported_domains* is fetched
  from https://www.google.com/supported_domains

searx/autocomplete.py:
  Reversed engineered autocomplete from Google WEB.  Supports Google's languages and
  subdomains.  The old API suggestqueries.google.com/complete has been replaced
  by the async REST API: https://{subdomain}/complete/search?{args}

searx/engines/google.py
  Reverse engineering and extensive testing ..
  - fetch_traits():  Fetch languages & regions from Google properties.
  - always use the async REST API (formally known as 'use_mobile_ui')
  - use *supported_domains* from traits
  - improved the result list by fetching './/div[@data-content-feature]'
    and parsing the type of the various *content features* --> thumbnails are
    added

searx/engines/google_images.py
  Reverse engineering and extensive testing ..
  - fetch_traits():  Fetch languages & regions from Google properties.
  - use *supported_domains* from traits
  - if exists, freshness_date is added to the result
  - issue 1864: result list has been improved a lot (due to the new cr parameter)

searx/engines/google_news.py
  Reverse engineering and extensive testing ..
  - fetch_traits():  Fetch languages & regions from Google properties.
    *supported_domains* is not needed but a ceid list has been added.
  - different region handling compared to Google WEB
  - fixed for various languages & regions (due to the new ceid parameter) /
    avoid CONSENT page
  - Google News do no longer support time range
  - result list has been fixed: XPath of pub_date and pub_origin

searx/engines/google_videos.py
  - fetch_traits():  Fetch languages & regions from Google properties.
  - use *supported_domains* from traits
  - add paging support
  - implement a async request ('asearch': 'arc' & 'async':
    'use_ac:true,_fmt:html')
  - simplified code (thanks to '_fmt:html' request)
  - issue 1359: fixed xpath of video length data

searx/engines/google_scholar.py
  - fetch_traits():  Fetch languages & regions from Google properties.
  - use *supported_domains* from traits
  - request(): include patents & citations
  - response(): fixed CAPTCHA detection (Scholar has its own CATCHA manager)
  - hardening XPath to iterate over results
  - fixed XPath of pub_type (has been change from gs_ct1 to gs_cgt2 class)
  - issue 1769 fixed: new request implementation is no longer incompatible

5fb2071cb2 [fix] google & youtube - set EU consent cookie
This change the previous bypass method for Google consent using
``ucbcb=1`` (6face215b8) to accept the consent using ``CONSENT=YES+``.

The youtube_noapi and google have a similar API, at least for the consent[1].

Get CONSENT cookie from google reguest::

    curl -i "https://www.google.com/search?q=time&tbm=isch" \
         -A "Mozilla/5.0 (X11; Linux i686; rv:102.0) Gecko/20100101 Firefox/102.0" \
         | grep -i consent
    ...
    location: https://consent.google.com/m?continue=https://www.google.com/search?q%3Dtime%26tbm%3Disch&gl=DE&m=0&pc=irp&uxe=eomtm&hl=en-US&src=1
    set-cookie: CONSENT=PENDING+936; expires=Wed, 24-Jul-2024 11:26:20 GMT; path=/; domain=.google.com; Secure
    ...

PENDING & YES [2]:

  Google change the way for consent about YouTube cookies agreement in EU
  countries. Instead of showing a popup in the website, YouTube redirects the
  user to a new webpage at consent.youtube.com domain ...  Fix for this is to
  put a cookie CONSENT with YES+ value for every YouTube request

9328c66e93 [fix] google news - send CONSENT Cookie to not be redirected
In the EU there exists a "General Data Protection Regulation" [1] aka GDPR (BTW:
very user friendly!) which requires consent to tracking.  To get the consent
from the user, google-news requests are redirected to confirm and get a CONSENT
Cookie from https://consent.google.de/s?continue=...

This patch adds a CONSENT Cookie to the google-news request to avoid
redirection.

The behavior of the CONTENTS cookies over all google engines seems similar but
the pattern is not yet fully clear to me, here are some random samples from my
analysis ..

Using common google search from different domains::

    google.com:        CONSENT=YES+cb.{{date}}-14-p0.de+FX+816
    google.de:         CONSENT=YES+cb.{{date}}-14-p0.de+FX+333
    google.fr:         CONSENT=YES+srp.gws-{{date}}-0-RC2.fr+FX+826

When searching about videos (google-videos)::

    google.es:         CONSENT=YES+srp.gws-{{date}}-0-RC2.es+FX+076
    google.de:         CONSENT=YES+srp.gws-{{date}}-0-RC2.de+FX+171

Google news has only one domain for all languages::

    news.google.com:   CONSENT=YES+cb.{{date}}-14-p0.de+FX+816

Using google-scholar search from different domains::

    scholar.google.de: CONSENT=YES+cb.{{date}}-14-p0.de+FX+333
    scholar.google.fr: does not use such a cookie / did not ask the user
    scholar.google.es: does not use such a cookie / did not ask the user

Interim summary:

  Pattern is unclear and I won't apply the CONSENT cookie to all google engines.
  More experience is need before we generalize the CONSENT cookies over all
  google engines.

1c67b6aece [enh] google engine: supports "default language"
Same behaviour behaviour than Whoogle [1].  Only the google engine with the
"Default language" choice "(all)"" is changed by this patch.

When searching for a locate place, the result are in the expect language,
without missing results [2]:

  > When a language is not specified, the language interpretation is left up to
  > Google to decide how the search results should be delivered.

The query parameters are copied from Whoogle.  With the ``all`` language:

- add parameter ``source=lnt``
- don't use parameter ``lr``
- don't add a ``Accept-Language`` HTTP header.

The new signature of function ``get_lang_info()`` is:

    lang_info = get_lang_info(params, lang_list, custom_aliases, supported_any_language)

Argument ``supported_any_language`` is True for google.py and False for the other
google engines.  With this patch the function now returns:

- query parameters: ``lang_info['params']``
- HTTP headers: ``lang_info['headers']``
- and as before this patch:
  - ``lang_info['subdomain']``
  - ``lang_info['country']``
  - ``lang_info['language']``
