Since including rust in the builder stage of the image didn't address
the issues with building the cryptography library on armv7, that
architecture will just use the last supported version of the affected
libraries. May want to revisit this later.
Adds support for encoding (and optionally encrypting) user config values as
a single string that can be passed to any endpoint with the "preferences" url
param.

Sessions are no longer validated using the "/session/..." route. This
created a lot of problems due to buggy/unexpected behavior coming from
the Flask-Session dependency, which is (more or less) no longer
maintained.
Sessions are also no longer strictly server-side-only. The majority of
information that was being stored in user sessions was aesthetic only,
aside from the session specific key used to encrypt URLs. This key is
still unique per user, but is not (or shouldn't be) in anyone's threat
model to keep absolutely 100% private from everyone. Especially paranoid
users of Whoogle can easily modify the code to use a randomly generated
encryption key that is reset on session invalidation (and set
invalidation time to a short enough period for their liking).
Ultimately, this should result in much more stable sessions per client.
There shouldn't be decryption issues with element URLs or queries
during result page navigation.
* Expand `/window` endpoint to behave like a proxy
The `/window` endpoint was previously used as a type of proxy, but only
for removing Javascript from the result page. This expands the existing
functionality to allow users to proxy search result pages (with or without
Javascript) through their Whoogle instance.
* Implement filtering of remote content from css
* Condense NoJS feature into Anonymous View
Enabling NoJS now removes Javascript from the Anonymous View, rather
than creating a separate option.
* Exclude 'data:' urls from filter, add translations
The 'data:' url must be allowed in results to view certain elements on
the page, such as stars for review based results.
Add translations for the remaining languages.
* Add cssutils to requirements
This is a temporary reversion to 3.3.2 for the cryptography library.
There's an issue with buildx failing for the arm/v7 build, which is
directly related to cryptography versions > 3.3.2 (after the switch to
rust).
It might be acceptable to include the rust toolchain for armv7 builds,
but that adds a comical amount of time to the full cross platform build.
This introduces a new approach to handling user sessions, which should
allow for users to set more reliable config settings on public instances.
Previously, when a user with cookies disabled would update their config,
this would modify the app's default config file, which would in turn
cause new users to inherit these settings when visiting the app for the
first time and cause users to inherit these settings when their current
session cookie expired (which was after 30 days by default I believe).
There was also some half-baked logic for determining on the backend
whether or not a user had cookies disabled, which lead to some issues
with out of control session file creation by Flask.
Now, when a user visits the site, their initial request is forwarded to
a session/<session id> endpoint, and during that subsequent request
their current session id is matched against the one found in the url. If
the ids match, the user has cookies enabled. If not, their original
request is modified with a 'cookies_disabled' query param that tells
Flask not to bother trying to set up a new session for that user, and
instead just use the app's fallback Fernet key for encryption and the
default config.
Since attempting to create a session for a user with cookies disabled
creates a new session file, there is now also a clean-up routine included
in the new session decorator, which will remove all sessions that don't
include a valid key in the dict. NOTE!!! This means that current user
sessions on public instances will be cleared once this update is merged
in. In the long run that's a good thing though, since this will allow session
mgmt to be a lot more reliable overall for users regardless of their cookie
preference.
Individual user sessions still use a unique Fernet key for encrypting queries,
but users with cookies disabled will use the default app key for encryption
and decryption.
Sessions are also now (semi)permanent and have a lifetime of 1 year.
This allows the user to enable their preferred settings in a variety of
ways, depending on their deployment preference. Values added to
whoogle.env can be enabled using WHOOGLE_DOTENV=1, in which case all
values in the env var file will overwrite defaults or user provided
settings.

The lxml dependency in the project was fairly unnecessary, and made the
initial build time for the project considerably slower. This replaces
all instances of lxml with either the default html parser (for bs4
constructors) or the built in xml.etree package (for search suggestion
parsing).
* 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
* 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
Basic autocomplete/search suggestion functionality added
* Adds new GET and POST routes for '/autocomplete' that accept a string query and returns an array of suggestions
* Adds new autoscript.js file for handling queries on the main page and results view
* Updated requests class to include autocomplete method
* Updated opensearch template to handle search suggestions
* Added header template to allow for autocomplete on results view
* Updated readme to mention autocomplete feature
* Ignore venv when building docker file
* Remove reference to 8888 port
It wasn't really used anywhere, and setting it to 5000 everywhere removes ambiguity, and makes things easier to track and reason about
* Use waitress rather than Flask's built in web server
It's not production grade
* Actually add waitress to requirements
Woops!
Pushing straight to master since this is an extremely simple fix, with
a pretty large performance benefit.
The Phyme library used for generating a User Agent rhyme was consuming
an absolute unit of memory. Now that it's removed, it's using about 10x
less memory, at the cost of User Agents being not as funny anymore.
- Updated Dockerfile to include chmod of run script
- Added app.json for Heroku quick deploy
- Removed unused function var in js controller
- Moved requirements back to root of repo
- Added Codebeat report to readme
