Dinesh 4afce5d94d apple_auth: Change BUNDLE_ID setting to APP_ID everywhere.
The apple developer webapp consistently refers this App ID. So,
this clears any confusion that can occur.

Since python social auth only requires us to include App ID in
_AUDIENCE(a list), we do that in computed settings making it easier for
server admin and we make it much clear by having it set to
APP_ID instead of BUNDLE_ID.

Dinesh c15d7e3202 requirements: Update social-auth-core to latest version.
Uses git release as this version 3.4.0 is not released to pypi.
This is required for removing some overriden functions of
apple auth backend class AppleAuthBackend.

With the update we also make following changes:

* Fix full name being populated as "None None".
c5c74f27dd that's included in update assigns first_name and last_name
to None when no name is provided by apple. Due to this our
code is filling return_data['full_name'] to 'None None'.
This commit fixes it by making first and last name strings empty.

* Remove decode_id_token override.
Python social auth merged the PR we sent including the changes
we made to decode_id_token function. So, now there is no
necessity for the override.

* Add _AUDIENCE setting in computed_settings.py.
`decode_id_token` is dependent on this setting.

to ensure it is consistently loaded early enough.

It is placed behind a check for SENTRY_DSN soas to not incur the
additional overhead of importing the `sentry_sdk` modules if Sentry is

Mateusz Mandera 6a50911032 auth: Allow signing in to an existing account with noreply github email.
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.

Steve Howell c44500175d database: Remove short_name from UserProfile.
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.

Rohitt Vashishtha 912e372c4e markdown: Remove !avatar() and !gravatar() syntax.
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:

`![avatar for Alice](/avatar/1234?s=50) 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.

Mateusz Mandera d51afcf485 emails: Improve handling of timeouts when sending.
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.

Aman Agrawal 5b7917da5f notifications: Remove support for unbatched push removal events.
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.

wowol fec77381ee urls: Migrate zproject urls to use modern django patterns.
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
review and think about the individual changes.

Modified by tabbott to convert back to `re_path` various URLs with
strings that had been converted to use `path()` with string
validation to simplify review.

This commit adds `name` attribute for the backends that do not

Dinesh d30f11888a logging: Set up a different logger for each backend.
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`.

This implementation adds a new key `inactive_user_id`

Mateusz Mandera dd40649e04 queue_processors: Remove the slow_queries queue.
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.

Dinesh a3329f288c auth: Modify `filter_usable_emails` to only exclude noreply github emails.
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

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.

Steve Howell e47e1cd648 droplet settings: Fix hostname-related settings.
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.

Instead of sneakily injecting HttpOnly into the cookie via the path
setting, use the setting that was designed for this purpose.

Anders Kaseorg dce6b4a40f middleware: Remove unused cookie_domain setting.
Since commit 1d72629dc4, we have been
maintaining a patched copy of Django’s
SessionMiddleware.process_response in order to unconditionally ignore
our own optional cookie_domain setting that we don’t set.

Instead, let’s not do that.

Mateusz Mandera e86cfbdbd7 rate_limiter: Store data in request._ratelimits_applied list.
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.

Dinesh fb361c7257 auth: Set `development_only=True` for `SOCIAL_AUTH_GITLAB_KEY`.
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.

Mateusz Mandera 8069133f88 rate_limit: Remove __str__ methods of RateLimitedObjects.
These were clunky from the start and are no longer used, as keys are now
used directly for logging purposes.

Mateusz Mandera 4e9f77a6c4 rate_limit: Adjust keys() of some RateLimitedObjects.
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().
