login_context now gets the social_backends list through
get_social_backend_dicts and we move display_logo customization
to backend class definition.
This prepares for easily adding multiple IdP support in SAML
authentication - there will be a social_backend dict for each configured
IdP, also allowing display_name and icon customization per IdP.
any_oauth_backend_enabled is all about whether we will have extra
buttons on the login/register pages for logging in with some non-native
backends (like Github, Google etc.). And this isn't about specifically
oauth backends, but generally "social" backends - that may not rely
specifically rely on Oauth. This will have more concrete relevance when
SAML authentication is added - which will be a "social" backend,
requiring an additional button, but not Oauth-based.
The `LocalUploadBackend` returns a relative URL, while the `S3UploadBackend`
returns an absolute URL. This commit switches to using `urljoin` to obtain the
absolute URL, instead of simply joining strings.
This makes the implementation of `get_realm` consistent with its
declared return type of `Realm` rather than `Optional[Realm]`.
Fixes#12263.

Previously, we had some expensive-to-calculate keys in
zulip_default_context, especially around enabled authentication
backends, which in total were a significant contributor to the
performance of various logged-out pages. Now, these keys are only
computed for the login/registration pages where they are needed.
This is a moderate performance optimization for the loading time of
many logged-out pages.
Closes#11929.
This avoids a bunch of duplicated calls to auth_enabled_helper for our
social auth backends, which added up because auth_enabled_helper can
take 100us to run.
We have a few code paths that call get_realm_from_request multiple
times on the same request (e.g. the login page), once inside the view
function and once inside the common context processor code. This
change saves a useless duplicate database query in those code paths.
We never intended to render them for this use case as the result would
not look good, and now we have a convenient bugdown option for
controlling this behavior.
Since we're not storing the markdown rendering anywhere, there's
conveniently no data migration required.
Fixes#11889.
This logic for passing through whether the user was logged in never
worked, because we were trying to read the client.
Fix this, and add tests to ensure it never breaks again.
Restructured by tabbott to have completely different code with the
same intent.
Fixes#11802.
The night logo synchronization on the settings page was perfect, but
the actual display logic had a few problems:
* We were including the realm_logo in context_processors, even though
it is only used in home.py.
* We used different variable names for the templating in navbar.html
than anywhere else the codebase.
* The behavior that the night logo would default to the day logo if
only one was uploaded was not correctly implemented for the navbar
position, either in the synchronization for updates code or the
logic in the navbar.html templates.
This adds a new realm_logo field, which is a horizontal-format logo to
be displayed in the top-left corner of the webapp, and any other
places where we might want a wide-format branding of the organization.
Tweaked significantly by tabbott to rebase, fix styling, etc.
Fixing the styling of this feature's loading indicator caused me to
notice the loading indicator for the realm_icon feature was also ugly,
so I fixed that too.
Fixes#7995.
This was part of the logic to handle EXTERNAL_API_PATH varying.
But also it was already no longer used -- it was only ever passed
into template contexts, as `external_api_uri`, and it'd been
overtaken there by `external_api_uri_subdomain`.
So, update our dev docs to reflect that, and eliminate the variable.
This setting isn't documented at all, and I believe nobody has used it
since the end of api.zulip.com in 2016. So we get to complete the
cleanup of this logic.
These are just instances that jumped out at me while working on the
subdomains code, mostly while grepping for get_subdomain call sites.
I haven't attempted a comprehensive search, and there are likely
still others left.
The original "quality score" was invented purely for populating
our password-strength progress bar, and isn't expressed in terms
that are particularly meaningful. For configuration and the core
accept/reject logic, it's better to use units that are readily
understood. Switch to those.
I considered using "bits of entropy", defined loosely as the log
of this number, but both the zxcvbn paper and the linked CACM
article (which I recommend!) are written in terms of the number
of guesses. And reading (most of) those two papers made me
less happy about referring to "entropy" in our terminology.
I already knew that notion was a little fuzzy if looked at
too closely, and I gained a better appreciation of how it's
contributed to confusion in discussing password policies and
to adoption of perverse policies that favor "Password1!" over
"derived unusual ravioli raft". So, "guesses" it is.
And although the log is handy for some analysis purposes
(certainly for a graph like those in the zxcvbn paper), it adds
a layer of abstraction, and I think makes it harder to think
clearly about attacks, especially in the online setting. So
just use the actual number, and if someone wants to set a
gigantic value, they will have the pleasure of seeing just
how many digits are involved.
(Thanks to @YJDave for a prototype that the code changes in this
commit are based on.)
