Anecdotally, using SearX over unreliable proxies,
like tor, seems to be quite error prone.
SearX puts quite an effort to measure the
performance and reliability of engines, most
likely owning to those aspects being of
significant concern.
The patch here proposes to mitigate related
problems, by issuing concurrent redundant requests
through the specified proxies at once, returning
the first response that is not an error.
The functionality is enabled using the:
`proxy_request_redundancy` parameter within the
outgoing network settings or the engine settings.
Example:
```yaml
outgoing:
request_timeout: 8.0
proxies:
"all://":
- socks5h://tor:9050
- socks5h://tor1:9050
- socks5h://tor2:9050
- socks5h://tor3:9050
proxy_request_redundancy: 4
```
In this example, each network request will be
send 4 times, once through every proxy. The
first (non-error) response wins.
In my testing environment using several tor proxy
end-points, this approach almost entirely
removes engine errors related to timeouts
and denied requests. The latency of the
network system is also improved.
The implementation, uses a
`AsyncParallelTransport(httpx.AsyncBaseTransport)`
wrapper to wrap multiple sub-trasports,
and `asyncio.wait` to wait on the first completed
request.
The existing implementation of the network
proxy cycling has also been moved into the
`AsyncParallelTransport` class, which should
improve network client memoization and
performance.
TESTED:
- unit tests for the new functions and classes.
- tested on desktop PC with 10+ upstream proxies
and comparable request redundancy.
In the past, some files were tested with the standard profile, others with a
profile in which most of the messages were switched off ... some files were not
checked at all.
- ``PYLINT_SEARXNG_DISABLE_OPTION`` has been abolished
- the distinction ``# lint: pylint`` is no longer necessary
- the pylint tasks have been reduced from three to two
1. ./searx/engines -> lint engines with additional builtins
2. ./searx ./searxng_extra ./tests -> lint all other python files

The change in the hotkey mechanism introduced in 317db5b04 does not allow
configuration via `settings.yml`. This commit adds that functionality.
Closes: #2898
This patch fixes some quirks and issues related to the engines and the network.
Each engine has its own network and this network was broken for the following
engines[1]:
- archlinux
- bing
- dailymotion
- duckduckgo
- google
- peertube
- startpage
- wikipedia
Since the files have been touched anyway, the type annotaions of the engine
modules has also been completed so that error messages from the type checker are
no longer reported.

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).

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.
Make suspended_time changeable in settings.yml
Allow different values to be set for different exceptions.

- the environment variable SEARXNG_REDIS_URL overrides the setting value redis.url
- ./manage sets SEARXNG_REDIS_URL to unix:///usr/local/searxng-redis/run/redis.sock if:
- the socket exists
- SEARXNG_REDIS_URL is not already defined

settings.yml:
* The default URL was unix:///usr/local/searxng-redis/run/redis.sock?db=0
* The default URL is now "false"
The default URL makes the log difficult to deal with:
if the admin didn't install a Redis instance, the logs record a false error.
It worked before because SearXNG initialized the Redis connection when the limiter started.
In this commit, SearXNG initializes Redis in searx/webapp.py
so various components can use Redis without taking care of the initialization step.
Some administrators may want to hide the link to public_instances: If you run a
private instance for a company that wants there employees to use the private
instance instead of any of the public instances.
Add a new setting: general.donation_url
By default the value is https://docs.searxng.org/donate.html
When the value is false, the link is hidden
When the value is true, the link goes to the infopage donation,
the administrator can create a custom page.
Since PR 932 [1][2] static files can't be delivered by HTTP server any longer.
This patch makes the hash paramter in the URL of static files:
/static/themes/simple/css/searxng.min.css?5fde34a74bc438c7b56ec8c6501e131cc9914bd8
optional. By default the hash parameter is disabled.
HINT:
Instances that do not deliver static files by their HTTP server and have a
long expire time [3] should enable this option.
----
This is only a interim solution, on the long run:
make static.build.commit
creates files including the file name:
css/searxng-5fde34a74bc438c7b56ec8c6501e131cc9914bd8.min.css
and a mapping.json with this content[4]

The tab icon names are currently hard coded in the templates.
This commit lets us introduce an icon property in the future, e.g:
categories_as_tabs:

Add a redis connector, the default DB connector is a socket at::
unix:///usr/local/searxng-redis/run/redis.sock?db=0
To set up a redis instance simply use::
$ ./manage redis.build
$ sudo -H ./manage redis.install
A hint for developers:
To get access rights to this instance, your developer account needs to be added
to the *searxng-redis* group::
$ sudo -H ./manage redis.addgrp "${USER}"
# don't forget to logout & login to get member of group

Previously all categories were displayed as search engine tabs.
This commit changes that so that only the categories listed under
categories_as_tabs in settings.yml are displayed.
This lets us introduce more categories without cluttering up the UI.
Categories not displayed as tabs can still be searched with !bangs.
* disable by default
* settings.yml: ui.query_in_title
* in /preferences: privacy tab
when enabled, the result page's title contains the user query.
previously:
* oscar theme: the query was always included
* simple theme: the query was included with the GET method
