Anders Kaseorg a552c2e5f9 auth: Use the clipboard instead of zulip:// for desktop auth flow.
This does not rely on the desktop app being able to register for the
zulip:// scheme (which is problematic with, for example, the AppImage
format).

It also is a better interface for managing changes to the system,
since the implementation exists almost entirely in the server/webapp
project.

This provides a smoother user experience, where the user doesn't need
to do the paste step, when combined with
https://github.com/zulip/zulip-desktop/pull/943.

Fixes #13613.

Mateusz Mandera f1ec02b40a auth: Add ExternalAuthResult to manage data in authentication flows.
This new type eliminates a bunch of messy code that previously
involved passing around long lists of mixed positional keyword and
arguments, instead using a consistent data object for communicating
about the state of an external authentication (constructed in
backends.py).

The result is a significantly more readable interface between
zproject/backends.py and zerver/views/auth.py, though likely more
could be done.

This has the side effect of renaming fields for internally passed
structures from name->full_name, next->redirect_to; this results in
most of the test codebase changes.

Modified by tabbott to add comments and collaboratively rewrite the
initialization logic.

Anders Kaseorg fead14951c python: Convert assignment type annotations to Python 3.6 style.
This commit was split by tabbott; this piece covers the vast majority
of files in Zulip, but excludes scripts/, tools/, and puppet/ to help
ensure we at least show the right error messages for Xenial systems.

We can likely further refine the remaining pieces with some testing.

Hashir Sarwar e3b90a5ec8 api: Add a monotonic integer "feature level" for non-webapp clients.
The purpose is to provide a way for (non-webapp) clients,
like the mobile and terminal apps, to tell whether the
server it's talking to is new enough to support a given
API feature -- in particular a way that

* is finer-grained than release numbers, so that for
features developed after e.g. 2.1.0 we can use them
immediately on servers deployed from master (like
chat.zulip.org and zulipchat.com) without waiting the
months until a 2.2 release;

* is reliable, unlike e.g. looking at the number of
commits since a release;

* doesn't lead to a growing bag of named feature flags
which the server has to go on sending forever.

Tweaked by tabbott to extend the documentation.

Closes #14618.

Mateusz Mandera 8686bbf637 auth: Show a user-facing page when wrong token given to /subdomain/.
This used to show a blank page. Considering that the links remain valid

the user.

Graham Bleaney 2fe9d85a5f redirects: Refactor redirect code to use central helper function.
This commit introduces two new functions in 'url_encoding.py' which
centralize two common patterns for constructing redirect URLs. It
also migrates the files using those patterns to use the new
functions.

Dinesh 5888d7c0f5 auth: Change how config error URLs are configured.
URLs for config errors were configured seperately for each error
which is better handled by having error name as argument in URL.
A new view `config_error_view` is added containing context for
each error that returns `config_error` page with the relevant
context.
Also fixed tests and some views in `auth.py` to be consistent with
changes.

Mateusz Mandera f5e95c4fc1 requirements: Bump python-social-auth version.
We had a bunch of ugly hacks to monkey patch things due to upstream
being temporarily unmaintained and not merging PRs. Now the project is
active again and the fixes have been merged and included in the latest
version - so we clean up all that code.

Mateusz Mandera f2903e9c70 auth: Refactor - convert remote_username to email in remote_user_sso.
So far the conversion was in a very random place -
register_remote_user(). All other codepaths that use
login_or_register_remote_user() call it with the user's email address.
Making remote_user_sso convert remote_username to the email address
before calling login_or_register_remote_user makes this usage consistent
across the board.

Mateusz Mandera 98ae2fb940 auth: Remove redundant realm argument to finish_desktop_flow.
finish_desktop_flow is called with the assumption that the request
successfully proved control over the user_profile and generates a
special link to log into the user_profile account. There's no reason to
pass the realm param, as user_profile.realm can be assumed.

Dinesh 1308544a70 auth: Remove `if` blocks to redirect to config error page.

constructed setting names.

Mateusz Mandera bde495db87 registration: Add support for mobile and desktop flows.

this.

views.auth to backends.py causes circular import issue.

Mateusz Mandera 8d987ba5ae auth: Use tokens, with data stored in redis, for log_into_subdomain.
The desktop otp flow (to be added in next commits) will want to generate
one-time tokens for the app that will allow it to obtain an
authenticated session. log_into_subdomain will be the endpoint to pass
the one-time token to. Currently it uses signed data as its input
"tokens", which is not compatible with the otp flow, which requires
simpler (and fixed-length) token. Thus the correct scheme to use is to
store the authenticated data in redis and return a token tied to the
data, which should be passed to the log_into_subdomain endpoint.

In this commit, we replace the "pass signed data around" scheme with the
redis scheme, because there's no point having both.

Mateusz Mandera bce50ee652 auth: Use authenticate_remote_user in remote_user_jwt.
authenticate_remote_user already takes care of calling the authenticate
with the dummy backend. Also, return_data is not used and catching
DoesNotExist exception is not needed, as the dummy backend just returns
None if user isn't found.

Mateusz Mandera 2f38bc669f auth: Set request._email to user.delivery_email instead of user.email.
In other places where we set request._email, we set it to the

settings, where user.email will be useless.

Mateusz Mandera 5aded51b73 register: Pre-populate Name in social backend flow.
By adding some additional plumbing (through PreregistrationUser) of the
full_name and an additional full_name_validated option, we
pre-populate the Full Name field in the registration form when coming
through a social backend (google/github/saml/etc.) and potentially skip
the registration form (if the user would have nothing to do there other
than clicking the Confirm button) and just create the account and log
the user in.

Mateusz Mandera 34a540bacb context: Rename social_backends to external_authentication_methods.
The main purpose of this is to make that name change happen in
/server_settings. external_authentication_methods is a much better, more
descriptive name than social_backends from API perspective.
2019-11-03 15:55:44 -08:00
Mateusz Mandera 29314f3195 api: Remove unused /get_auth_backends endpoint.
This legacy endpoint was designed for the original native Zulip mobile
apps, which were deprecated years ago in favor of the React Native
app.

It was replaced by /server_settings for active use years ago, so it's
safe to remove it now.

display_name and display_logo (the name and icon to show on the "Log in

the configured IdP dictionaries.
