In [1] and [2] we discussed the need of a Result.results property and how we can
avoid unclear code. This patch implements a class for the reslut-lists of
engines::
searx.result_types.EngineResults
A simple example for the usage in engine development::
from searx.result_types import EngineResults
...
def response(resp) -> EngineResults:
res = EngineResults()
...
res.add( res.types.Answer(answer="lorem ipsum ..", url="https://example.org") )
...
return res

Typification of SearXNG
=======================
This patch introduces the typing of the results. The why and how is described
in the documentation, please generate the documentation ..
$ make docs.clean docs.live
and read the following articles in the "Developer documentation":
- result types --> http://0.0.0.0:8000/dev/result_types/index.html
The result types are available from the `searx.result_types` module. The
following have been implemented so far:
- base result type: `searx.result_type.Result`
--> http://0.0.0.0:8000/dev/result_types/base_result.html
- answer results
--> http://0.0.0.0:8000/dev/result_types/answer.html
including the type for translations (inspired by #3925). For all other
types (which still need to be set up in subsequent PRs), template documentation
has been created for the transition period.
Doc of the fields used in Templates
===================================
The template documentation is the basis for the typing and is the first complete
documentation of the results (needed for engine development). It is the
"working paper" (the plan) with which further typifications can be implemented
in subsequent PRs.
- https://github.com/searxng/searxng/issues/357
Answer Templates
================
With the new (sub) types for `Answer`, the templates for the answers have also
been revised, `Translation` are now displayed with collapsible entries (inspired
by #3925).
!en-de dog
Plugins & Answerer
==================
The implementation for `Plugin` and `Answer` has been revised, see
documentation:
- Plugin: http://0.0.0.0:8000/dev/plugins/index.html
- Answerer: http://0.0.0.0:8000/dev/answerers/index.html
With `AnswerStorage` and `AnswerStorage` to manage those items (in follow up
PRs, `ArticleStorage`, `InfoStorage` and .. will be implemented)
Autocomplete
============
The autocompletion had a bug where the results from `Answer` had not been shown
in the past. To test activate autocompletion and try search terms for which we
have answerers
- statistics: type `min 1 2 3` .. in the completion list you should find an
entry like `[de] min(1, 2, 3) = 1`
- random: type `random uuid` .. in the completion list, the first item is a
random UUID
Extended Types
==============
SearXNG extends e.g. the request and response types of flask and httpx, a module
has been set up for type extensions:
- Extended Types
--> http://0.0.0.0:8000/dev/extended_types.html
Unit-Tests
==========
The unit tests have been completely revised. In the previous implementation,
the runtime (the global variables such as `searx.settings`) was not initialized
before each test, so the runtime environment with which a test ran was always
determined by the tests that ran before it. This was also the reason why we
sometimes had to observe non-deterministic errors in the tests in the past:
- https://github.com/searxng/searxng/issues/2988 is one example for the Runtime
issues, with non-deterministic behavior ..
- https://github.com/searxng/searxng/pull/3650
- https://github.com/searxng/searxng/pull/3654
- https://github.com/searxng/searxng/pull/3642#issuecomment-2226884469
- https://github.com/searxng/searxng/pull/3746#issuecomment-2300965005
Why msgspec.Struct
==================
We have already discussed typing based on e.g. `TypeDict` or `dataclass` in the past:
- https://github.com/searxng/searxng/pull/1562/files
- https://gist.github.com/dalf/972eb05e7a9bee161487132a7de244d2
- https://github.com/searxng/searxng/pull/1412/files
- https://github.com/searxng/searxng/pull/1356
In my opinion, TypeDict is unsuitable because the objects are still dictionaries
and not instances of classes / the `dataclass` are classes but ...
The `msgspec.Struct` combine the advantages of typing, runtime behaviour and
also offer the option of (fast) serializing (incl. type check) the objects.
Currently not possible but conceivable with `msgspec`: Outsourcing the engines
into separate processes, what possibilities this opens up in the future is left
to the imagination!
Internally, we have already defined that it is desirable to decouple the
development of the engines from the development of the SearXNG core / The
serialization of the `Result` objects is a prerequisite for this.
HINT: The threads listed above were the template for this PR, even though the
implementation here is based on msgspec. They should also be an inspiration for
the following PRs of typification, as the models and implementations can provide
a good direction.
Why just one commit?
====================
I tried to create several (thematically separated) commits, but gave up at some
point ... there are too many things to tackle at once / The comprehensibility of
the commits would not be improved by a thematic separation. On the contrary, we
would have to make multiple changes at the same places and the goal of a change
would be vaguely recognizable in the fog of the commits.

The user_agent attribute of the Flask request object is an instance of
the werkzeug.user_agent.UserAgent class.

The intention of this PR is to modernize the settings_loader implementations.
The concept is old (remember, this is partly from 2014), back then we only had
one config file, meanwhile we have had a folder with config files for a very
long time. Callers can now load a YAML configuration from this folder as
follows ::
settings_loader.get_yaml_cfg('my-config.yml')
- BTW this is a fix of #3557.
- Further the `existing_filename_or_none` construct dates back to times when
there was not yet a `pathlib.Path` in all Python versions we supported in the
past.
- Typehints have been added wherever appropriate
At the same time, this patch should also be downward compatible and not
introduce a new environment variable. The localization of the folder with the
configurations is further based on:
SEARXNG_SETTINGS_PATH (wich defaults to /etc/searxng/settings.yml)
Which means, the default config folder is `/etc/searxng/`.
ATTENTION: intended functional changes!
If SEARXNG_SETTINGS_PATH was set and pointed to a not existing file, the
previous implementation silently loaded the default configuration. This
behavior has been changed: if the file or folder does not exist, an
EnvironmentError exception will be thrown in future.

This change does the following things:
- the `ip` keyword is now case-insensitive
- if the query includes `my ip` it will now also match
In order to avoid too many false matches, the `ip` keyword alone matches only if
it's the _only_ word, but the inclusion of `my` loosens that to be inclusive of
users type a phrase (eg, "what is my ip", "tell me my ip", "my IP address",
etc).
Better answer context
Previously this plugin simply dumped your IP or user-agent string as an answer.
This tiny change just adds some text to contextualize those answers (eg, "Your
IP is: 1.2.3.4" instead of just "1.2.3.4").
- l10n support: parse and format decimal numbers by babel
- ability to add additional units
- improved unit detection (symbols are not unique)
- support for alias units (0,010C to F --> 32,018 °F)

checked at all.
- ``PYLINT_SEARXNG_DISABLE_OPTION`` has been abolished
- the distinction ``# lint: pylint`` is no longer necessary

This patch was inspired by the discussion around PR-2882 [2]. The goals of this
patch are:
1. Convert plugin searx.plugin.limiter to normal code [1]
2. isolation of botdetection from the limiter [2]
3. searx/{tools => botdetection}/config.py and drop searx.tools
4. in URL /config, 'limiter.enabled' is true only if the limiter is really
enabled (Redis is available).
This patch moves all the code that belongs to botdetection into namespace
searx.botdetection and code that belongs to limiter is placed in namespace
searx.limiter.
Tthe limiter used to be a plugin at some point botdetection was added, it was
not a plugin. The modularization of these two components was long overdue.
With the clear modularization, the documentation could then also be organized
according to the architecture.

For correct determination of the IP to the request the function
botdetection.get_real_ip() is implemented. This fonction is used in the
ip_limit and link_token method of the botdetection and it is used in the
self_info plugin.
A documentation about the X-Forwarded-For header has been added.

- counting requests in LONG_WINDOW and BURST_WINDOW is not needed when the
request is validated by the link_token method [1]
- renew a ping-key on validation [2], this is needed for infinite scrolling,
where no new token (CSS) is loaded. / this does not fix the BURST_MAX issue in
the vanilla limiter
- normalize the counter names of the ip_limit method to 'ip_limit.*'
- just integrate the ip_limit method straight forward in the limiter plugin /
non intermediate code --> ip_limit now returns None or a werkzeug.Response
object that can be passed by the plugin to the flask application / non
intermediate code that returns a tuple

Block requests from PetalBlock. Normally robots.txt is enough to stop
PetalBlock from making requests [1]. However, if SearXNG is offered below a
path (example.org/search), then the robots.txt is not available in the root

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.
- Add documentation to the plugin
- Harmonize FastText language model with SearXNG's language model
