Alexandre Flament 3863f5a83f [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']``

Markus Heiser 34d7d97e1e [fix] youtube - 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, youtube requests are redirected to confirm and get a CONSENT
Cookie from https://consent.youtube.com

This patch adds a CONSENT Cookie to the youtube request to avoid redirection.

Markus Heiser f637bfc635 [mod] oscar's "default" template should make use of result.thumbnail
Some engine do have set result.img_src, other return a result.thumbnail.  If
result.img_src is unset and a result.thumbnail is given, show it to the UI.

Markus Heiser 062d589f86 [fix] xpath expressions to grap all items from bandcamp's response
I also found some items missing a thumbnail and I used text_extract for content
and title, to remove unneeded whitespaces.

BTW: added bandcamp's favicon

Markus Heiser 9c10b15096 [fix] settings_loader.py - use update_dict only for mapping types
I can't set `default_doi_resolver` in `settings.yml` if I'm using
`use_default_settings`.  Searx seems to try to interpret all settings at root
level in `settings.yml` as dict, which is correct except for
`default_doi_resolver` which is at root level and a string::

    File "/usr/lib/python3.9/site-packages/searx/settings_loader.py", line 125, in load_settings
        update_settings(default_settings, user_settings)
    File "/usr/lib/python3.9/site-packages/searx/settings_loader.py", line 61, in update_settings
        update_dict(default_settings[k], v)
    File "/usr/lib/python3.9/site-packages/searx/settings_loader.py", line 48, in update_dict
        for k, v in user_dict.items():
    AttributeError: 'str' object has no attribute 'items'

[fix] url_for(..., _external=True) in templates
2021-04-05 14:50:39 +02:00
Markus Heiser 87e4c47621 [fix] url_for(..., _external=True) in templates
The `url_for` function in the template context is not the one from Flask, it is
the one from `webapp`.  The `webapp.url_for_theme` is different from its
namesake of Flask and has it quirks, when called with argument `_external=True`.

The `webapp.url_for_theme` can't handle absolute URLs since it pokes a leading
'/', here is the snippet of the old code::

    url = url_for(endpoint, **values)
    if settings['server']['base_url']:
        if url.startswith('/'):
            url = url[1:]
        url = urljoin(settings['server']['base_url'], url)

Next drawback of (Flask's) `_external=True` is, that it will not return the HTTP
scheme when searx (the Flask app) listens on http and is proxied by a https
server.

To get the right scheme `HTTP_X_SCHEME` is needed by Flask (werkzeug).  Since
this is not provided in every environment (e.g. behind Apache mod_wsgi or the
HTTP header is not fully set for some other reasons) it is recommended to
get *script_name*, *server* and *scheme* from the configured `base_url`.  If
`base_url` is specified, then these values from are given preference over any
Flask's generics.

BTW this patch normalize to use `url_for` in the `opensearch.xml` and drop the
need of `host` and `urljoin` in template's context.
