Switch to defusedxml for xml parsing
xml.etree.ElementTree.fromstring is considered insecure, see:
https://docs.python.org/3/library/xml.etree.elementtree.html

The defusedxml package contains several Python-only workarounds and
fixes for denial of service and other vulnerabilities in Python's XML
libraries: https://github.com/tiran/defusedxml

Catch invalid XML in suggestion response
As reported in #593, the XML response body returned for search
suggestions can apparently contain invalid XML elements. This catches
the error and returns an empty suggestion list instead of erroring.

Remove default country param
The country URL param ('gl') is no longer set to 'US' by default, and is
omitted from the search entirely unless explicitly set by the user. This
change was made in an attempt to cut back on the number of captchas
experienced by certain users self-hosting who experienced a decreased
amount of captchas when this configuration setting was removed.

Use farside.link for frontend alternatives in results (#560)
* Integrate Farside into Whoogle

When instances are ratelimited (when a captcha is returned instead of
the user's search results) the user can now hop to a new instance via
Farside, a new backend service that redirects users to working instances
of a particular frontend. In this case, it presents a user with a
Farside link to a new Whoogle (or Searx) instance instead, so that the
user can resume their search.

For the generated Farside->Whoogle link, the generated link includes the
user's current Whoogle configuration settings as URL params, to ensure a
more seamless transition between instances. This doesn't translate to
the Farside->Searx link, but potentially could with some changes.

* Expand conversion of config<->url params

Config settings can now be translated to and from URL params using a
predetermined set of "safe" keys (i.e. config settings that easily
translate to URL params).

* Allow jumping instances via Farside when ratelimited

When instances are ratelimited (when a captcha is returned instead of
the user's search results) the user can now hop to a new instance via
Farside, a new backend service that redirects users to working instances
of a particular frontend. In this case, it presents a user with a
Farside link to a new Whoogle (or Searx) instance instead, so that the

Fix incorrect request type for image searches
Previously had hardcoded POST requests for all requests that didn't use
the header template (which currently is only the image tab).

Also refactored how the Filter class works. It now requires a valid
Config model to be provided, which is then set up as a class var that
the filtering functions can use as needed, rather than setting specific
values from the config as individual values (which was confusing and
sloppy).

Use 'gl' search param to set country
This switches the param used for the "country" config setting from "cr"
(which only filters results by the country the result is hosted in) to
"gl" (which overrides server/hosting location and produces results that
are more accurate for the user's current country).

Before this change, the country config setting was (imo) pretty useless.
Allowing a user to override an instance's hosting location with their
preferred country though is way more useful, especially for public
instances that are hosted in a different country than the user.

Make base search url a member of the request class
Since the request class is loaded prior to values being read from the
user's dotenv, the WHOOGLE_RESULT_PER_PAGE var wasn't being used for
searches.

This moves the definition of the base search url to be intialized in the
request class to address this issue.

Revert changes to default language config
A recent issue brought up a good point about how the latest changes to
setting default language to english break functionality for bilingual
users. The change was likely not the best solution for users who were
being affected by IP geolocation on their instances -- the right
solution for that would be to configure the interface/search language to
their preference instead.

Fix handling of http (vs https) proxy creation
The requests library requires both 'http' and 'https' values in any
included proxy dict, and whoogle was previously copying the http proxy
to https for simplicity. The assumption was that if the underlying
request wasn't able to connect via https, it would default to http
(otherwise why have the requirement to specify both?)

This led to connectivity issues for users with http only proxies as of
the latest urllib and requests package versions, which are a lot more
strict with connections over https. With the latest versions, if an
https connection cannot be made, the library returns an error.

As a result, the new proxy dict must look something like this for plain
http proxies:

{'http': 'http://domain.tld:port', 'https': 'http://domain.tld:port'}

where both http and https are identical, but both are still required.

Add fallback interface/search lang + cleanup
Since the interface language defaults to IP geolocation by google, the
default language is now set to english. Still not sure if this is the
best solution, but at least temporarily should clear up some confusion
for users with instances deployed in countries outside of their own.

Also performed some minor cleanup:
  - Updated name of strip_blocked_sites to clean_query
  - Added clean_query to list of jinja template functions
  - Ensured site block list doesn't contain duplicate filters

Hotfix: remove site filter for maps links
The new site filter breaks links to Maps results, so filter.py needed
to be updated to handle these links as a unique case. A new method was
introduced to easily remove any "-site:..." filters from the query,
which is now also used to format queries in the header template rather
than manually removing the blocked site list within the template itself.

Bumps version to 0.5.1 for releasing the bugfix

Block websites from search results via user config (#304)
* Block websites in search results via user config

Adds a new config field "Block" to specify a comma separated list of
websites to block in search results. This is applied for all searches.

* Add test for blocking sites from search results

* Document WHOOGLE_CONFIG_BLOCK usage

* Strip '-site:' filters from query in header template

The 'behind the scenes' site filter applied for blocked sites was
appearing in the query field when navigating between search categories
(all -> images -> news, etc). This prevents the filter from appearing in
all except "images", since the image category uses a separate header.
This should eventually be addressed when the image page can begin using
the standard whoogle header, but until then, the filter will still
appear for image searches.

df0b7afa50 Switch to single Fernet key per session
This moves away from the previous (messy) approach of using two separate
keys for decrypting text and element URLs separately and regenerating
them for new searches. The current implementation of sessions is not very
reliable, which lead to keys being regenerated too soon, which would
break page navigation. Until that can be addressed, the single
key per session approach should work a lot better.

Add tor and http/socks proxy support (#137)
* Add tor and http/socks proxy support

Allows users to enable/disable tor from the config menu, which will
forward all requests through Tor.

Also adds support for setting environment variables for alternative
proxy support. Setting the following variables will forward requests
through the proxy:
    - WHOOGLE_PROXY_USER (optional)
    - WHOOGLE_PROXY_PASS (optional)
    - WHOOGLE_PROXY_TYPE (required)
      - Can be "http", "socks4", or "socks5"
    - WHOOGLE_PROXY_LOC  (required)
      - Format: "<ip address>:<port>"

See #30

* Refactor acquire_tor_conn -> acquire_tor_identity

Also updated travis CI to set up tor

* Add check for Tor socket on init, improve Tor error handling

Initializing the app sends a heartbeat request to Tor to check for
availability, and updates the home page config options accordingly. This
heartbeat is sent on every request, to ensure Tor support can be
reconfigured without restarting the entire app.

If Tor support is enabled, and a subsequent request fails, then a new
TorError exception is raised, and the Tor feature is disabled until a
valid connection is restored.

The max attempts has been updated to 10, since 5 seemed a bit too low
for how quickly the attempts go by.

* Change send_tor_signal arg type, update function doc

send_tor_signal now accepts a stem.Signal arg (a bit cleaner tbh). Also
added the doc string for the "disable" attribute in TorError.

* Fix tor identity logic in Request.send

* Update proxy init, change proxyloc var name

Proxy is now only initialized if both type and location are specified,
as neither have a default fallback and both are required. I suppose the
type could fall back to http, but seems safer this way.

Also refactored proxyurl -> proxyloc for the runtime args in order to
match the Dockerfile args.

* Add tor/proxy support for Docker builds, fix opensearch/init

The Dockerfile is now updated to include support for Tor configuration,
with a working torrc file included in the repo.

An issue with opensearch was fixed as well, which was uncovered during
testing and was simple enough to fix here. Likewise, DDG bang gen was
updated to only ever happen if the file didn't exist previously, as
testing with the file being regenerated every time was tedious.

* Add missing "@" for socks proxy requests

Privacy respecting alternatives in results view (#106)
Full implementation of social media alt redirects (twitter/youtube/instagram -> nitter/invidious/bibliogram) depending on configuration.

Verbatim search and option to ignore search autocorrect are now supported as well.

Also cleaned up the javascript side of whoogle config so that it now
uses arrays of available fields for parsing config values instead of manually assigning each
one to a variable.

This doesn't include support for Google Maps -> Open Street Maps, that
seems a bit more involved than the social media redirects were, so it
should likely be a separate effort.

Project refactor (#85)
* Major refactor of requests and session management

- Switches from pycurl to requests library
  - Allows for less janky decoding, especially with non-latin character
  sets
- Adds session level management of user configs
  - Allows for each session to set its own config (people are probably
  going to complain about this, though not sure if it'll be the same
  number of people who are upset that their friends/family have to share
  their config)
- Updates key gen/regen to more aggressively swap out keys after each
request

* Added ability to save/load configs by name

- New PUT method for config allows changing config with specified name
- New methods in js controller to handle loading/saving of configs

* Result formatting and removal of unused elements

- Fixed question section formatting from results page (added appropriate
padding and made questions styled as italic)
- Removed user agent display from main config settings

* Minor change to button label

* Fixed issue with "de-pickling" of flask session

Having a gitignore-everything ("*") file within a flask session folder seems to cause a
weird bug where the state of the app becomes unusable from continuously
trying to prune files listed in the gitignore (and it can't prune '*').

* Switched to pickling saved configs

* Updated ad/sponsored content filter and conf naming

Configs are now named with a .conf extension to allow for easier manual
cleanup/modification of named config files

Sponsored content now removed by basic string matching of span content

* Version bump to 0.2.0

* Fixed request.send return style

0c0ebb8917 Added POST search, encrypted query strings, refactoring
The implementation of POST search support comes with a few benefits. The
most apparent is the avoidance of search queries appearing in web server
logs -- instead of the prior GET approach (i.e.
/search?q=my+search+query), using POST requests with the query stored in
the request body creates logs that simply appear as "/search".

Since a lot of relative links are generated in the results page, I came
up with a way to generate a unique key at run time that is used to
encrypt any query strings before sending to the user. This benefits both
regular text queries as well as fetching of image links and means that
web logs will only show an encrypted string where a link or query
string might slip through.

Unfortunately, GET search requests still need to be supported, as it
doesn't seem that Firefox (on iOS) supports loading search engines by
their opensearch.xml file, but instead relies on manual entry of a
search query string. Once this is updated, I'll probably remove GET
request search support.
