The method EngineTraits.get_region(..) returns engine's region string
that **best fits** to SearXNG's locale. This means it returns a
region (country) if only a language is set in the locale. By example the method
returns for a locale tag `es` a region `ES`.
Google's search parameter `cr` restricts search results to documents originating
in a particular country / in case of a locale tag (language) as described above,
this argument should be unset in the query send to Google.

* this is a small fix to increase the colspan of the category in engine preferences from 7 to 8, since there was a column added
=> fixing a small fallout from 4731290317
incident:
flask_babel.gettext() does not work in the engine modules.
cause:
the request() and response() functions of the engine modules run in the
processor, whose search() method runs in a thread and in the threads the
context of the Flask app does not exist. The context of the Flask app is
needed by the gettext() function for the L10n.
Solution:
copy context of the Flask app into the threads. [1]
special case:
We cannot equip the search() method of the processors with the decorator [1],
because the decorator requires a context (Flask app) that does not yet exist
at the time of the initialization of the processors (the initialization of the
processors is part of the initialization of the Flask app).

The monolithic implementation of the limiter was divided into methods and
implemented in the Python package searx.botdetection. Detailed documentation on
the methods has been added.
The methods are divided into two groups:
1. Probe HTTP headers
- Method http_accept
- Method http_accept_encoding
- Method http_accept_language
- Method http_connection
- Method http_user_agent
2. Rate limit:
- Method ip_limit
- Method link_token (new)
The (reduced) implementation of the limiter is now in the module
searx.botdetection.limiter. The first group was transferred unchanged to this
module. The ip_limit contains the sliding windows implemented by the limiter so
far.
This merge also fixes some long outstandig issue:
- limiter does not evaluate the Accept-Language correct [1]
- limiter needs a IPv6 prefix to block networks instead of IPs [2]
Without additional configuration the limiter works as before (apart from the
bugfixes). For the commissioning of additional methods (link_toke), a
configuration must be made in an additional configuration file. Without this
configuration, the limiter runs as before (zero configuration).
The ip_limit Method implements the sliding windows of the vanilla limiter,
additionally the link_token method can be used in this method. The link_token
method can be used to investigate whether a request is suspicious. To activate
the link_token method in the ip_limit method add the following to your
/etc/searxng/limiter.toml::
[botdetection.ip_limit]
link_token = true

Over the years, the preferences template became an unmanageable beast. To make
the source code more readable the monolith is splitted into elements. The
splitting into elements also has the advantage that a new template can make use
of them.
The reversed checkbox is a quirk that is only used in the prefereces and must be
eliminated in the long term. For this the macro 'checkbox_onoff_reversed' was
added to the preferences.html template. The 'checkbox' macro is also a quirk of
the preferences.html we don't want to use in other templates (it is an
input-checkbox in a HTML form that was misused for status display).

In my tests I see bots rotating IPs (with endless IP lists). If such a bot has
100 IPs and has three attempts (SUSPICIOUS_IP_MAX = 3) then it can successfully
send up to 300 requests in one day while rotating the IP. To block the bots for
a longer period of time the SUSPICIOUS_IP_WINDOW, as the time period in which an
IP is observed, must be increased.
For normal WEB-browsers this is no problem, because the SUSPICIOUS_IP_WINDOW is
deleted as soon as the CSS with the token is loaded.
SUSPICIOUS_IP_WINDOW = 3600 * 24 * 30
Time (sec) before sliding window for one suspicious IP expires.

Follow up of #2269
The script to update the descriptions of the engines does no longer work since
PR #2269 has been merged.
searx/engines/wikipedia.py
==========================
1. There was a misusage of zh-classical.wikipedia.org:
- `zh-classical` is dedicate to classical Chinese [1] which is not
traditional Chinese [2].
- zh.wikipedia.org has LanguageConverter enabled [3] and is going to
dynamically show simplified or traditional Chinese according to the
HTTP Accept-Language header.
2. The update_engine_descriptions.py needs a list of all wikipedias. The
implementation from #2269 included only a reduced list:
- https://meta.wikimedia.org/wiki/Wikipedia_article_depth
- https://meta.wikimedia.org/wiki/List_of_Wikipedias
searxng_extra/update/update_engine_descriptions.py

Before PR #2269 there was a match_language() function that did an approximation
using various methods. With PR #2269 there are only the types in the data model
of the languages, which can be recognized by babel. The approximation methods,
which are needed (only here) in the determination of the descriptions, must be
replaced by other methods.

This patch replaces the *full of magic* ``utils.match_language`` function by a
``locales.match_locale``. The ``locales.match_locale`` function is based on the
``locales.build_engine_locales`` introduced in 9ae409a0 [1].
In the past SearXNG did only support a search by a language but not in a region.
This has been changed a long time ago and regions have been added to SearXNG
core but not to the engines. The ``utils.match_language`` was the function to
handle the different aspects of language/regions in SearXNG core and the
supported *languages* in the engine. The ``utils.match_language`` did it with
some magic and works good for most use cases but fails in some edge case.
To replace the concurrence of languages and regions in the SearXNG core the
``locales.build_engine_locales`` was introduced in 9ae409a0 [1]. With the last
patches all engines has been migrated to a ``fetch_traits`` and a
language/region concept that is based on ``locales.build_engine_locales``.
To summarize: there is no longer a need for the ``locales.match_language``.

Partial reverse engineering of the DuckDuckGo (DDG) engines including a
improved language and region handling based on the enigne.traits_v1 data.
- DDG Lite
- DDG Instant Answer API
- DDG Images
- DDG Weather
docs/src/searx.engine.duckduckgo.rst:
Online documentation of the DDG engines (make docs.live)
searx/data/engine_traits.json
Add data type "traits_v1" generated by the fetch_traits() functions from:
- "duckduckgo" (WEB),
- "duckduckgo images" and
- "duckduckgo weather"
and remove data from obsolete data type "supported_languages".
searx/autocomplete.py:
Reversed engineered Autocomplete from DDG. Supports DDG's languages.
searx/engines/duckduckgo.py:
- fetch_traits(): Fetch languages & regions from DDG.
- get_ddg_lang(): Get DDG's language identifier from SearXNG's locale. DDG
defines its languages by region codes. DDG-Lite does not offer a language
selection to the user, only a region can be selected by the user.
- Cache ``vqd`` value: The vqd value depends on the query string and is needed
for the follow up pages or the images loaded by a XMLHttpRequest (DDG
images). The ``vqd`` value of a search term is stored for 10min in the
redis DB.
- DDG Lite engine: reversed engineered request method with improved Language
and region support and better ``vqd`` handling.
searx/engines/duckduckgo_definitions.py: DDG Instant Answer API
The *instant answers* API does not support languages, or at least we could not
find out how language support should work. It seems that most of the features
are based on English terms.
searx/engines/duckduckgo_images.py: DDG Images
Reversed engineered request method. Improved language and region handling
based on cookies and the enigne.traits_v1 data. Response: add image format to
the result list
searx/engines/duckduckgo_weather.py: DDG Weather
Improved language and region handling based on cookies and the
enigne.traits_v1 data.

One reason for the often seen CAPTCHA of the Startpage requests are the
incomplete requests SearXNG sends to startpage.com: this patch is a complete new
implementation of the ``request()`` function, reversed engineered from the
Startpage's search form. The new implementation:
- use traits of data_type: traits_v1 and drop deprecated data_type: supported_languages
- adds time-range support
- adds save-search support
- fix searxng/searxng/issues 1884
- fix searxng/searxng/issues 1081 --> improvements to avoid CAPTCHA
In preparation for more categories (News, Images, Videos ..) from Startpage, the
variable ``startpage_categ`` was set up. The default value is ``web`` and other
categories from Startpage are not yet implemented.

With the language and region tags from the EngineTraitsMap the handling of
SearXNG's tags of languages and regions has been normalized and is no longer
a *mystery*. The "languages" became "locales" that are supported by babel and
by this, the update_engine_traits.py can be simplified a lot.
Other code places can be simplified as well, but these simplifications
should (respectively can) only be done when none of the engines work with the
deprecated EngineTraits.supported_languages interface anymore.
This commit replaces searx.languages by searx.sxng_locales and fix the naming of
some names from "language" to "locale" (e.g. language_codes --> sxng_locales).

Implementations of the *traits* of the engines.
Engine's traits are fetched from the origin engine and stored in a JSON file in
the *data folder*. Most often traits are languages and region codes and their
mapping from SearXNG's representation to the representation in the origin search
engine.
To load traits from the persistence::
searx.enginelib.traits.EngineTraitsMap.from_data()
For new traits new properties can be added to the class::
searx.enginelib.traits.EngineTraits
.. hint::
Implementation is downward compatible to the deprecated *supported_languages
method* from the vintage implementation.
The vintage code is tagged as *deprecated* an can be removed when all engines
has been ported to the *traits method*.

From the analyse of @9Ninety [1] we know that DDG (and may be other engines / I
have startpage in mind) does some kind of TLS fingerprint to block bots.
This patch shuffles the default ciphers from httpx to avoid a cipher profile
that is known to httpx (and blocked by DDG).

From `What Is TLS Fingerprint and How to Bypass It`_

When the user choose "Auto-detected", the choice remains on the following queries.
The detected language is displayed.
For example "Auto-detected (en)":
* the next query language is going to be auto detected
* for the current query, the detected language is English.
This replace the autodetect_search_language plugin.
Tineye becomes active as soon as a https:// signature is found in the search
term, but most of the time a reverse image search is not requested when a URL is
specified, often the URL is just from a C&P.
The frequent requests to tineye lead in the end to the SearXNG instance being
blocked by tineye and the user seeing unexpected error messages.
BTW: many maintainers have disabled this engine in their local SearXNG settings.
