* 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
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

HINT: this patch has no functional change / it is the preparation for following
changes and bugfixes
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 order to be able to meet the outstanding requirements, the implementation is
modularized and supplemented with documentation.
This patch does not contain functional change, except it fixes issue #2455
----
Aktivate limiter in the settings.yml and simulate a bot request by::
curl -H 'Accept-Language: de-DE,en-US;q=0.7,en;q=0.3' \
-H 'Accept: text/html'
-H 'User-Agent: xyz' \
-H 'Accept-Encoding: gzip' \
'http://127.0.0.1:8888/search?q=foo'
In the LOG:
DEBUG searx.botdetection.link_token : missing ping for this request: .....
Since ``BURST_MAX_SUSPICIOUS = 2`` you can repeat the query above two time
before you get a "Too Many Requests" response.

If there were no results but errors in the engines then the error dialogs of the
engines was displayed in the result list.
With the new design errors of the engines should only be displayed in the
sidebar and at the same time duplications of the (template) code will be
avoided.

* set border top and bottom on sidebar collasables
* inrease peading on summary so its easier to click on mobile
* remove margins and add flex wrapper to normalize elements in sidebar
Make elements in the sidebar collapse able. Except infoboxes all elements in
the sidebar are collapsed by default.
By folding out the sidebar elements, the UI looks less cluttered. Especially on
small devices like smartphones, where the sidebar is above the results list, the
UX should be improved [1].
