In particular importing gitter data leads to having accounts with these
noreply github emails. We generally only want users to have emails that
we can actually send messages to, so we'll keep the old behavior of
disallowing sign up with such an email address. However, if an account
of this type already exists, we should allow the user to have access to
it.
A few major themes here:
- We remove short_name from UserProfile
and add the appropriate migration.
- We remove short_name from various
cache-related lists of fields.
- We allow import tools to continue to
write short_name to their export files,
and then we simply ignore the field
at import time.
- We change functions like do_create_user,
create_user_profile, etc.
- We keep short_name in the /json/bots
API. (It actually gets turned into
an email.)
- We don't modify our LDAP code much
here.
This particular commit has been a long time coming. For reference,
!avatar(email) was an undocumented syntax that simply rendered an
inline 50px avatar for a user in a message, essentially allowing
you to create a user pill like:
`!avatar(alice@example.com) Alice: hey!`
---
Reimplementation
If we decide to reimplement this or a similar feature in the future,
we could use something like `<avatar:userid>` syntax which is more
in line with creating links in markdown. Even then, it would not be
a good idea to add this instead of supporting inline images directly.
Since any usecases of such a syntax are in automation, we do not need
to make it userfriendly and something like the following is a better
implementation that doesn't need a custom syntax:
` Alice: hey!`
---
History
We initially added this syntax back in 2012 and it was 'deprecated'
from the get go. Here's what the original commit had to say about
the new syntax:
> We'll use this internally for the commit bot. We might eventually
> disable it for external users.
We eventually did start using this for our github integrations in 2013
but since then, those integrations have been neglected in favor of
our GitHub webhooks which do not use this syntax.
When we copied `!gravatar` to add the `!avatar` syntax, we also noted
that we want to deprecate the `!gravatar` syntax entirely - in 2013!
Since then, we haven't advertised either of these syntaxes anywhere
in our docs, and the only two places where this syntax remains is
our game bots that could easily do without these, and the git commit
integration that we have deprecated anyway.
We do not have any evidence of someone asking about this syntax on
chat.zulip.org when developing an integration and rightfully so- only
the people who work on Zulip (and specifically, markdown) are likely
to stumble upon it and try it out.
This is also the only peice of code due to which we had to look up
emails -> userid mapping in our backend markdown. By removing this,
we entirely remove the backend markdown's dependency on user emails
to render messages.

We use the EMAIL_TIMEOUT django setting to timeout after 15s of trying
to send an email. This will nicely lead to retries in the email_senders
queue, due to the retry_send_email_failures decorator.
smtlib documentation suggests that socket.timeout can be raised as the
result of timing out, so in attempts I'm getting
smtplib.SMTPServerDisconnected. Either way, seems appropriate to add
socket.timeout to the exception that we catch.
I checked that this does not interfere with the MRO of the auth

We remove support for the old clients which required an event for
each message to clear notification.
This is justified since it has been around 1.5 years since we started
supporting the bulk operation (and so essentially nobody is using a
mobile app version so old that it doesn't support the batched
approach) and the unbatched approach has a maintenance and reliability
cost.
There is still some miscellaneous cleanup that
has to happen for things like analytics queries
and dead code in node tests, but this should
remove the main use of pointers in the backend.
(We will also still need to drop the DB field.)
Due to authentication restrictions, a deployment may need to direct
traffic for mobile applications to an alternate uri to take advantage
alternate authentication mechansism. By default the standard realm URI
will be usedm but if overridden in the settings file, an alternate uri
can be substituted.
Because of other validation on these values, I don't believe any of
these does anything different, but these changes improve readability
and likely make GitHub's code scanners happy.
I believe the Bundle ID (aka App ID) and Services ID have meaning only
relative to a specific Team ID. In particular, in some places in the
developer.apple.com UI, they're displayed in a fully-qualified form
like "ABCDE12345.com.example.app", where "com.example.app" is the
App ID or Services ID and ABCDE12345 is the Team ID.
Adds the ability to set a SAML attribute which contains a
list of subdomains the user is allowed to access. This allows a Zulip
server with multiple organizations to filter using SAML attributes
which organization each user can access.

This migrations use of url() to path() or re_path(). In this commit,
we only migration regular expressions to path where the translation is trivial:
* URLs with no parameters in them
* URLs with only integer parameters in them
* Strings where there regular expression just checked for `/`s
path; strings, which can have variable validation in the URLs that
need by-hand auditing, we leave for future commits that are easier to

This was written by Rishi for a very brief purpose a few years ago,
and it doesn't serve much purpose now other than to be a place we
update in code sweeps.
We're migrating to using the cleaner zulip.com domain, which involves
changing all of our links from ReadTheDocs and other places to point
to the cleaner URL.
This commit adds `name` attribute for the backends that do not
have them.
This is just a kind of prep commit in case if we want to use
`self.logger.xxxx()` in the future which is dependent on the
`name` attribute. But right now these logging calls aren't used
anywhere in those backends.
`HTTPError` has empty string for `str(HTTPError())`. Logging it
as it is would not be much helpful. So, this commits adds code
to log the name of error also.
Adds a top-level logger in `settings.LOGGING` `zulip.auth`
with the default handlers `DEFAULT_ZULIP_HANDLERS` and
an extra hanlder that writes to `/var/log/zulip/auth.log`.
Each auth backend uses it's own logger, `self.logger` which
is in form 'zulip.auth.<backend name>'.
This way it's clear which auth backend generated the log
and is easier to look for all authentication logs in one file.
Besides the above mentioned changes, `name` attribute is added to
`ZulipAuthMixin` so that these logging kind of calls wouldn't raise
any issues when logging is tried in a class without `name` attribute.
Also in the tests we use a new way to check if logger calls are made
i.e. we use `assertLogs` to test if something is logged.
Thanks to Mateusz Mandera for the idea of having a seperate logger
for auth backends and suggestion of using `assertLogs`.

We change do_create_user and create_user to accept
role as a parameter instead of 'is_realm_admin' and 'is_guest'.
These changes are done to minimize data conversions between
role and boolean fields.
Earlier this `standard_relay_params` was used only for SAML auth,
now "Sign in with Apple" also requires this to store those params
in session for reuse. So, this acts as a prep commit for "Sign in
with Apple" auth support.
This will protect us in case of some kinds of bugs that could allow
making requests such as password authentication attempts to tornado.
Without restricting the domains to which the in-memory backend can
be applied, such bugs would lead to attackers having multiple times
larger rate limits for these sensitive requests.
Helps to see if users are often trying to login with deactived
accounts.
A use case: Trackdown whether any deactivated bot users are still
trying to access the API.
This implementation adds a new key `inactive_user_id`
to `return_data` in the function `is_user_active` which
check if a `user_profile` is active. This reduces the effort
of getting `user_id` just before logging.
Modified tests for line coverage.
Instead of plumbing the idp to /complete/saml/ through redis, it's much
more natural to just figure it out from the SAMLResponse, because the
information is there.
This is also a preparatory step for adding IdP-initiated sign in, for
which it is important for /complete/saml/ to be able to figure out which
IdP the request is coming from.
If the IdP authentication API is flaky for some reason, it can return
bad http responses, which will raise HTTPError inside
python-social-auth. We don't want to generate a traceback
in those cases, but simply log the exception and fail gracefully.
While this functionality to post slow queries to a Zulip stream was
very useful in the early days of Zulip, when there were only a few
hundred accounts, it's long since been useless since (1) the total
request volume on larger Zulip servers run by Zulip developers, and
(2) other server operators don't want real-time notifications of slow
backend queries. The right structure for this is just a log file.
We get rid of the queue and replace it with a "zulip.slow_queries"
logger, which will still log to /var/log/zulip/slow_queries.log for
ease of access to this information and propagate to the other logging
handlers. Reducing the amount of queues is good for lowering zulip's
memory footprint and restart performance, since we run at least one
dedicated queue worker process for each one in most configurations.
It appears that a recent pika release started logging spammy INFO
output on the pika.connection and pika.channel channels, in addition
to the existing pika.adapters channel.
It's probably best to just move to WARNING-level logging for all of these.
This significantly cleans up the output when run-dev.py restarts
services due to a code change in the development environment.
Instead of having to filter `@noreply.github.com` emails in
`get_unverified_emails`, it's good to make `filter_usable_emails`
just filter `@noreply.github.com` and handle verified/unverified
part in their respective functions because of `@noreply.github.com`
exception being a fiddly special-case detail.
Also renamed `filter_usable_emails` to `get_usable_email_objects`
as a line that gets all associated github emails is removed in
`get_verified_emails` and `get_unverified_emails` and added to
`filter_usable_emails`. The name `filter_usable_emails` suggests
that it just filters given emails, whereas here it's getting all
associated email objects and returning usable emails.
This commit extends the template for "choose email" to mention for
users who have unverified emails that they need to verify them before
using them for Zulip authentication.
Also modified `social_auth_test_finish` to assert if all emails
are present in "choose email" screen as we need unverified emails
to be shown to user and verified emails to login/signup.
Fixes#12638 as this was the last task for that issue.
This separates the part of code that gets all the emails associated
to GitHub from `get_verified_emails` in `GitHubAuthBackend`.
Improves readability of code and acts as a preparatory commit for
extending the template for "choose email" in GitHub auth flow to also
list any unverified emails that have an associated Zulip account in
the organization.
The trailing slash has no good reason to be there and is also
inconsistent with how we instruct to set up Audience Restriction in the
Okta SAML setup docs for the dev environment.
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.
We recently changed our droplet setup such that their
host names no longer include zulipdev.org. This caused
a few things to break.
The particular symptom that this commit fixes is that
we were trying to server static assets from
showell:9991 instead of showell.zulipdev.org:9991,
which meant that you couldn't use the app locally.
(The server would start, but the site's pretty unusable
without static assets.)
Now we rely 100% on `dev_settings.py` to set
`EXTERNAL_HOST` for any droplet users who don't set
that var in their own environment. That allows us to
remove some essentially duplicate code in `run-dev.py`.
We also set `IS_DEV_DROPLET` explicitly, so that other
code doesn't have to make inferences or duplicate
logic to detemine whether we're a droplet or not.
And then in `settings.py` we use `IS_DEV_DROPLET` to
know that we can use a prod-like method of calculating
`STATIC_URL`, instead of hard coding `localhost`.
We may want to iterate on this further--this was
sort of a quick fix to get droplets functional again.
It's possible we can re-configure droplets to have
folks get reasonable `EXTERNAL_HOST` settings in their
bash profiles, or something like that, although that
may have its own tradeoffs.

The information used to be stored in a request._ratelimit dict, but
there's no need for that, and a list is a simpler structure, so this
allows us to simplify the plumbing somewhat.
In development env, we use `get_secret` to get
`SOCIAL_AUTH_GITLAB_KEY` from `dev-secrets.conf`. But in
production env, we don't need this as we ask the user
to set that value in `prod_settings_template.py`.
This restricts the code from looking `zulip-secrets.conf`
for `social_auth_gitlab_key` in production env.
type().__name__ is sufficient, and much readable than type(), so it's
better to use the former for keys.
We also make the classes consistent in forming the keys in the format
type(self).__name__:identifier and adjust logger.warning and statsd to
take advantage of that and simply log the key().
The previous model for GitHub authentication was as follows:
* If the user has only one verified email address, we'll generally just log them in to that account
* If the user has multiple verified email addresses, we will always
prompt them to pick which one to use, with the one registered as
"primary" in GitHub listed at the top.
This change fixes the situation for users going through a "login" flow
(not registration) where exactly one of the emails has an account in
the Zulip oragnization -- they should just be logged in.
Fixes part of #12638.
URLs for config errors were configured seperately for each error

Also fixed tests and some views in `auth.py` to be consistent with
changes.
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.
We plan to use these records to check and record the schema of Zulip's
events for the purposes of API documentation.
Based on an original messier commit by tabbott.
In theory, a nicer version of this would be able to work directly off
the mypy type system, but this will be good enough for our use case.
Now called:
validate_email_not_already_in_realm
We have a separate validation function that
makes sure that the email fits into a realm's
domain scheme, and we want to avoid naming
confusion here.
We need to request access to read:org scope to be able to check org/team
membership. Without it SOCIAL_AUTH_GITHUB_ORG_NAME and
SOCIAL_AUTH_GITHUB_TEAM_ID settings don't work and simply lead to all
auth attempts failing.
