Steve Howell 80acbb9fdf Clean up `test_get_all_profiles_avatar_urls`.
This test was using the anti-pattern of doing an
assertion inside a conditional.

I added the `findOne` helper to make it easier
to write robust tests for scenarios like this.

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.

Steve Howell ca74cd6e37 bug fix: Fix unread counts for certain API messages.
If I send a message from a normal Zulip client, it is
considered to be "read" by me.  But if I send it via
an API program (using my human account), the message
is not immediately "read" by me.

Now we handle this correctly in `get_raw_unread_data`.

The symptom of this was that these messages would get
"stuck" in "Private Messages" narrows until the next
time you reloaded your app.

Tim Abbott 1b95a1dea7 hello: Focus on distributed teams as use case.
I've always thought of distributed teams as the place where Zulip
really shines over other tools, because chat is much more important in
that context.

And I've always been kinda unhappy with "most productive team chat" as
a line.

There's a lot more we should do here, but this is a start.

Steve Howell 1b16693526 tests: Limit email-based logins.
We now have this API...

If you really just need to log in
and not do anything with the actual
user:

    self.login('hamlet')

If you're gonna use the user in the
rest of the test:

    hamlet = self.example_user('hamlet')
    self.login_user(hamlet)

If you are specifically testing
email/password logins (used only in 4 places):

    self.login_by_email(email, password)

And for failures uses this (used twice):

    self.assert_login_failure(email)

Steve Howell c235333041 test performance: Pass in users to api_* helpers.
This reduces query counts in some cases, since
we no longer need to look up the user again. In
particular, it reduces some noise when we
count queries for O(N)-related tests.

The query count is usually reduced by 2 per
API call.  We no longer need to look up Realm
and UserProfile.  In most cases we are saving
these lookups for the whole tests, since we
usually already have the `user` objects for
other reasons.  In a few places we are simply
moving where that query happens within the
test.

In some places I shorten names like `test_user`
or `user_profile` to just be `user`.
2020-03-11 14:18:29 -07:00
Steve Howell 626ad0078d tests: Add uuid_get and uuid_post.
We want a clean codepath for the vast majority
of cases of using api_get/api_post, which now
uses email and which we'll soon convert to
accepting `user` as a parameter.

These apis that take two different types of
values for the same parameter make sweeps
like this kinda painful, and they're pretty
easy to avoid by extracting helpers to do
the actual common tasks.  So, for example,
here I still keep a common method to
actually encode the credentials (since
the whole encode/decode business is an
annoying detail that you don't want to fix
in two places):

    def encode_credentials(self, identifier: str, api_key: str) -> str:
        """
        identifier: Can be an email or a remote server uuid.
        """
        credentials = "%s:%s" % (identifier, api_key)
        return 'Basic ' + base64.b64encode(credentials.encode('utf-8')).decode('utf-8')

But then the rest of the code has two separate
codepaths.

And for the uuid functions, we no longer have
crufty references to realm.  (In fairness, realm
will also go away when we introduce users.)

For the `is_remote_server` helper, I just inlined
it, since it's now only needed in one place, and the
name didn't make total sense anyway, plus it wasn't
a super robust check.  In context, it's easier
just to use a comment now to say what we're doing:

    # If `role` doesn't look like an email, it might be a uuid.
    if settings.ZILENCER_ENABLED and role is not None and '@' not in role:
        # do stuff

2020-03-11 14:18:29 -07:00
Mateusz Mandera 89394fc1eb middleware: Use request.user for logging when possible.
Instead of trying to set the _requestor_for_logs attribute in all the
relevant places, we try to use request.user when possible (that will be
when it's a UserProfile or RemoteZulipServer as of now). In other
places, we set _requestor_for_logs to avoid manually editing the
request.user attribute, as it should mostly be left for Django to manage
it.
In places where we remove the "request._requestor_for_logs = ..." line,
it is clearly implied by the previous code (or the current surrounding
code) that request.user is of the correct type.

akashaviator 9c63976da5 api: Refactor get_members_backend in zerver/views/users.py.
This refactors get_members_backend to return user data of a single
user in the form of a dictionary (earlier being a list with a single
dictionary).

This also refactors it to return the data with an appropriate key
(inside a dictionary), "user" or "members", according to the type of
data being returned.

Tweaked by tabbott to use somewhat less opaque code and simple OpenAPI
descriptions.
2020-03-08 18:43:30 -07:00
Tim Abbott ccf63ac66b decorators: Restructure get_client_name interface.
Previously, get_client_name was responsible for both parsing the
User-Agent data as well as handling the override behavior that we want
to use "website" rather than "Mozilla" as the key for the Client object.

Now, it's just responsible for User-Agent, and the override behavior
is entirely within process_client (the function concerned with Client
objects).

This has the side effect of changing what `Client` object we'll use
for HTTP requests to /json/ endpoints that set the `client` attribute.
I think that's in line with our intent -- we only have a use case for
API clients overriding the User-Agent parsing (that feature is a
workaround for situations where the third party may not control HTTP
headers but does control the HTTP request payload).

This loses test coverage on the `request.GET['client']` code path; I
disable that for now since we don't have a real use for that behavior.

(We may want to change that logic to have Client recognize individual
browsers; doing so requires first using a better User-Agent parsing
library).

Part of #14067.

Tim Abbott 53cc00c21c messages: Ban the sender property when not mirroring.
The "sender" property in `send_message_backend` is meant to only do
something when doing Zephyr mirroring (or similar).  We should help
clients behave correctly by banning this property in requests that are
not specifically requesting mirroring behavior.

This commit requires changes to a number of tests that incorrectly
passed this parameter or didn't use the right setup for mirroring.

Tim Abbott cf897cc4b6 test_messages: Convert Zephyr mirror tests to use API.
The special Zephyr mirroring logic is only intended to be used via the
API, so this sets up a more effective test.  It also allows us to

authentication.

Mateusz Mandera fe0f381914 populate_db: Don't restrict email domains by default in tests and dev.
The email domain restriction to @zulip.com is annoying in development
environment when trying to test sign up. For consistency, it's best to
have tests use the same default, and the tests that require domain
restriction can be adjusted to set that configuration up for themselves
explicitly.

Tim Abbott 5835023021 tests: Use user IDs internally in send message helpers.
This uses the better, modern, user ID based API for sending messages
internally in the test suite, something that's convenient to do as a
follow-up to the migration to pass UserProfile objects to these
functions.
2020-03-07 18:31:13 -08:00
Steve Howell 5e2a32c936 tests: Use users in send_*_message.
This commit mostly makes our tests less
noisy, since emails are no longer an important
detail of sending messages (they're not even
really used in the API).

It also sets us up to have more scrutiny
on delivery_email/email in the future
for things that actually matter.  (This is
a prep commit for something along those
lines, kind of hard to explain the full
plan.)
2020-03-07 18:30:13 -08:00
Tim Abbott 9230213bde settings: Add EMAIL_ADDRESS_VISIBILITY_NOBODY.
This extends our email address visibility settings to deny access to
user email addresses even to organization administrators.

At the moment, they can of course change the setting (which leaves an
audit trail), but in the future only organization owners will be able
to change that setting.

While we're at this, we rewrite the settings_data.js test to cover all
the cases in a more consistent way.

Fixes #14111.
2020-03-06 16:34:08 -08:00
Steve Howell f2b8eef21a refactor: Avoid hacky use of ValidationError.code.
We were using `code` to pass around messages.

The `code` field is designed to be a code, not
a human-readable message.

It's possible that we don't actually need two
flavors of messages for these type of validations,
but I didn't want to change that yet.

We **definitely** don't need to put two types of
message in the exception, so I fix that.  Instead,
I just have the caller ask what level of detail
it needs.

I added a non-verbose message for the case of
system bots.

I removed the non-translated version of the message
for deactivated accounts, which didn't have test
coverage and is slightly more prone to leaking
email info that we don't want to leak.
2020-03-06 11:53:22 -08:00
Steve Howell 7e55cab429 invite performance: Reduce queries to find existing users.
In the prep commits leading up to this, we split
out two new helpers:

    validate_email_is_valid
    get_errors_for_new_emails

Now when we validate invites we use two separate
loops to filter our emails.

Note that the two extracted functions map to two
of the data structures that used to be handled
in a single loop, and now we break them out:

    errors = validate_email_is_valid
    skipped = get_errors_for_new_emails

The first loop checks that emails are even valid
to begin with.

The second loop finds out whether emails are already
in use.

The second loop takes advantage of this helper:

    get_errors_for_new_emails

The second helper can query all potential new emails
with a single round trip to the database.

This reduces our query count.

Steve Howell b35ffde5fb tests: Avoid calling actions.validate_email().
We are trying to kill off `validate_email`, so
we no longer call it from these tests.

These tests are already kind of low-level in
nature, so testing the more specific helpers
here should be fine.

Note that we also make the third parameter
to `validate_email` non-optional in this commit,
to preserve 100% coverage.  This is really just
refactoring noise--we will soon eliminate the
entire function, but I didn't want to do everything
in a huge commit.
2020-03-06 11:53:22 -08:00
Steve Howell 689aca9140 refactor: Extract validate_email_is_valid().
This has two goals:

    - sets up a future commit to bulk-validate
      emails

    - the extracted function is more simple,
      since it just has errors, and no codes
      or deactivated flags

This commit leaves us in a somewhat funny
intermediate state where we have
`action.validate_email` being a glorified
two-line function with strange parameters,
but subsequent commits will clean this up:

    - we will eliminate validate_email
    - we will move most of the guts of its
      other callee to lib/email_validation.py

To be clear, the code is correct here, just
kinda in an ugly, temporarily-disorganized
intermediate state.

Steve Howell 30b43605c3 invite performance: Reduce RealmDomain queries.
We now use the `get_realm_email_validator()`
helper to build an email validator outside
the loop of emails in our invite list.

This allows us to perform RealmDomain queries
only once per request, instead of once per
email.

Steve Howell c43a29ff54 invites: Fix bug with inviting cross realm bots.
Without the fix here, you will get an exception
similar to below if you try to invite one of the
cross realm bots.  (The actual exception is
a bit different due to some rebasing on my branch.)

	  File "/home/zulipdev/zulip/zerver/lib/request.py", line 368, in _wrapped_view_func
		return view_func(request, *args, **kwargs)
	  File "/home/zulipdev/zulip/zerver/views/invite.py", line 49, in invite_users_backend
		do_invite_users(user_profile, invitee_emails, streams, invite_as)
	  File "/home/zulipdev/zulip/zerver/lib/actions.py", line 5153, in do_invite_users
		email_error, email_skipped, deactivated = validate_email(user_profile, email)
	  File "/home/zulipdev/zulip/zerver/lib/actions.py", line 5069, in validate_email
		return None, (error.code), (error.params['deactivated'])
	TypeError: 'NoneType' object is not subscriptable

Obviously, you shouldn't try to invite a cross
realm bot to your realm, but we want a reasonable
error message.

RESOLUTION:

Populate the `code` parameter for `ValidationError`.

BACKGROUND:

Most callers to `validate_email_for_realm` simply catch
the `ValidationError` and then report a more generic error.

That's also what `do_invite_users` does, but it has the
somewhat convoluted codepath through `validate_email`
that triggers this code:

    try:
        validate_email_for_realm(user_profile.realm, email)
    except ValidationError as error:
        return None, (error.code), (error.params['deactivated'])

The way that we're using the `code` parameter for
`ValidationError` feels hacky to me.  The intention
behind `code` is to provide a descriptive error to
calling code, and it's not intended for humans, and
it feels strange that we actually translate this in
other places.  Here are the Django docs:

    https://docs.djangoproject.com/en/3.0/ref/forms/validation/

And then here's an example of us actually translating
a code (not part of this commit, just providing context):

    raise ValidationError(_('%s already has an account') %
                          (email,), code = _("Already has an account."),
                          params={'deactivated': False})

Those codes eventually get put into InvitationError, which
inherits from JsonableError, and we do actually display
these errors in the webapp:

    if skipped and len(skipped) == len(invitee_emails):
        # All e-mails were skipped, so we didn't actually invite anyone.
        raise InvitationError(_("We weren't able to invite anyone."),
                              skipped, sent_invitations=False)

I will try to untangle this somewhat in upcoming commits.
2020-03-06 11:53:22 -08:00
Steve Howell 923e6dcd5d tests: Add test for mirror_dummy user invites.
We allow folks to invite emails that are
associated with a mirror_dummy account.

We had a similar test already for registration,
but not invites.

This logic typically affects MIT realms in the
real world, but the logic should apply to any
realm, so I use accounts from the zulip realm
for convenient testing.  (For example, we might
run an IRC mirror for a non-MIT account.)
2020-03-06 11:53:22 -08:00
Steve Howell 332f8e7dde tests: Add query count check for invites.
I use a range here because there's some leak
from another test that causes the count to
vary.  Once we get this a bit more under control,
we should be able to analyze the leak better.
2020-03-06 11:53:22 -08:00
Steve Howell 32e1c22c88 tests: Improve test_invite_existing_user.
The substantive improvement here is to use
a strange casing for Hamlet's email, which
will prevent future casing bugs.

I also log in as Cordelia to prevent confusion
that the test has something to do with
inviting yourself.  It's more typical for
somebody to invite another person to a realm
(not realizing they're already there).

I also made two readability tweaks.

Steve Howell 504ec9d489 typing: Remove recipient-related complexity.
For historical reasons we were creating Recipient
objects at some point in the typing-notifications
codepath.  Now we just work with UserProfiles.
This removes some queries, as indicated by
the change to `len(queries)` in a couple of the
tests.

The one subtle thing that changes here is huddles.
If user 10 sends a typing notification that they
are talking to users 20 and 30, there might not
actually be a huddle for users 10/20/30, but
we were actually creating huddles on the fly!
There is no need to create huddles just for
typing notifications, since we don't even
share huddle ids with our clients.  The clients
just infer the huddles.

Some of the code that gets killed off here as
somewhat "collateral damage" is some
defensive code related to formerly supporting streams
in typing indicators.  The support for streams
was killed off almost as soon as we released
the feature, and the codepath is pretty clearly
user-centric at this point.
2020-02-28 12:46:20 -08:00
Steve Howell b26f2dcd4b typing: Deprecate emails in typing endpoint.
The only clients that should use the typing
indicators endpoint are our internal clients,
and they should send a JSON-formatted list
of user_ids.

Unfortunately, we still have some older versions
of mobile that still send emails.

In this commit we fix non-user-facing things
like docs and tests to promote the user_ids
interface that has existed since about version
2.0 of the server.

One annoyance is that we documented the
typing endpoint with emails, instead of the
more modern user_ids, which may have delayed
mobile converting to user_ids (and which
certainly caused confusion).  It's trivial
to update the docs, but we need to short
circuit one assertion in the openapi tests.

We also clean up the test structure for the
typing tests:

    TypingHappyPathTest.test_start_to_another_user
    TypingHappyPathTest.test_start_to_multiple_recipients
    TypingHappyPathTest.test_start_to_self
    TypingHappyPathTest.test_start_to_single_recipient

Cleanup includes:

    - Use early-exit for email case.
    - Rename helpers to get_validate_*.
    - Avoid clumsy rebuilding of lists in helpers.
    - Avoid the confusing `recipient` name (which
      can be confused with the model by the same
      name).
    - Just delegate duplicate-id/email-removal to
      the helpers.

The cleaner structure allows us to elminate a couple
mypy workarounds.

This fixes a confusing aspect of how our automated tests worked
previously, where we'd almost all HTTP requests in the unlikely

We need to adjust query counts in a few tests that now are a bit

Tim Abbott 800312c976 has_request_variables: Fix slow extraction of parameters.
A sloppy implementation of the main has_request_variables wrapper
function meant that it did two very inefficient things:

* To combine together the GET and POST parameters, it would make a
  copy of the request.GET QueryDict object, which combined with the
  fact that these objects are slow to access, consumed about 90us per
  argument.
* Doing this in a loop (one time per argument), rather than once,
  which resulted in us doing this 11 times for a `GET /events` query.

Fixing this to just make a dictionary and combine things with some
small loops saved about 1 millisecond from the total runtime of GET
/events (for comparison, the total actual work of that view function
is about 700ms).

We need to fix at least one test that used a bad mock HttpRequest
object that didn't have a .GET property.

rht 41e3db81be dependencies: Upgrade to Django 2.2.10.
Django 2.2.x is the next LTS release after Django 1.11.x; I expect
we'll be on it for a while, as Django 3.x won't have an LTS release
series out for a while.

Because of upstream API changes in Django, this commit includes
several changes beyond requirements and:

* urls: django.urls.resolvers.RegexURLPattern has been replaced by
  django.urls.resolvers.URLPattern; affects OpenAPI code and related
  features which re-parse Django's internals.
  https://code.djangoproject.com/ticket/28593
* test_runner: Change number to suffix. Django changed the name in this
  ticket: https://code.djangoproject.com/ticket/28578
* Delete now-unnecessary SameSite cookie code (it's now the default).
* forms: urlsafe_base64_encode returns string in Django 2.2.
  https://docs.djangoproject.com/en/2.2/ref/utils/#django.utils.http.urlsafe_base64_encode
* upload: Django's File.size property replaces _get_size().
  https://docs.djangoproject.com/en/2.2/_modules/django/core/files/base/
* process_queue: Migrate to new autoreload API.
* test_messages: Add an extra query caused by .refresh_from_db() losing
  the .select_related() on the Realm object.
* session: Sync SessionHostDomainMiddleware with Django 2.2.

There's a lot more we can do to take advantage of the new release;
this is tracked in #11341.

Tim Abbott cb2c96f736 test_templates: Remove shallow template rendering code.
This code was very useful when first implemented to help catch errors
where our backend templates didn't render, but has been superceded by
the success of our URL coverage testing (which ensures every URL
supported by Zulip's urls.py is accessed by our tests, with a few
exceptions) and other tests covering all of the emails Zulip sends.

It has a significant maintenance cost because it's a bit hacky and
involves generating fake context, so it makes sense to remove these.
Any future coverage issues with templates should be addressed with a
direct test that just accessing the relevant URL or sends the relevant
email.

Chris Heald 3236483d0e tests: Fix type reflection for Python 3.7.
In python 3.5-3.6, generic types had an __origin__ attribute which
indicated which generic they originated from; the code was reflecting on
that value to check types against the openapi spec. In python3.7, this
changed, and there's no longer an immediately simple way to get this
information in all cases. __origin__ appears to be the implementing
class now, returning `list` or `collections.abc.Iterator` rather than
`typing.List` and `typing.Iterator`. This adds a sloppy-but-effective
mechanism for inferring if a type maps to the List/Dict/Iterator/Mapping
types and gets the test suite passing again.

Steve Howell 1b6578cafd messages: Fix bug with commas in stream names.
We now validate streams with a separate
function from PM recipients.

It's confusing enough all the ways you can
encode a stream or encode the PM recipients,
but trying to do it all in one function was
hard to reason about and led to at least one
bug.

In particular, there was a bug where streams
with commas in them would get split.  Now
we just don't ever split on commas inside
of `extract_stream_indicator`.

Steve Howell 96132fe0e9 extract_recipients: Enforce str as incoming type.
After removing internal_send_message() in a recent

to our REQ mechanism that always passes strings
to converters.  (If there are default values,
REQ does not call the converters.)

We therefore make two changes:

    - use the more strict annotation of "str"
      for the `s` parameter

    - don't bother with the isinstance check

Steve Howell 2e8dec233e slow queries: Use internal_send_stream_message().
Note that while the test mocks the actual message
send, we now have a `get_stream` call in the queue
worker, so we have to set up a real stream for
testing (or we could have mocked that as well, but
it didn't seem necessary).  The setup queries add
to the amount of queries reported by the test,
plus the `get_stream` call.  I just made the
query count a digits regex, which is a little bit
lame, but I don't think it's worth risking test
flakes for this.

Steve Howell c4e3cfebb0 presence: Add realm_id to UserPresence.
This index is intended to optimize the performance of the very
frequently run query of "what is the presence status of all users in a
realm?".

Main changes:
    - add realm_id to UserPresence
    - add index for realm_id
    - backfill realm_id for old rows
    - change all writes to UserPresence to include
      realm_id

The index is of this form:

    "zerver_userpresence_realm_id_5c4ef5a9" btree (realm_id)

We will create an index on (realm_id, timestamp) in a
future commit, but I think it's a bit faster if you do
the backfill before the index.

There's also a minor tweak to the populate_db script.

Steve Howell b33552997e cross realm bots: Simplify notify_new_user.
Instead of having `notify_new_user` delegate
all the heavy lifting to `send_signup_message`,
we just rename `send_signup_message` to be
`notify_new_user` and remove the one-line
wrapper.

We remove a lot of obsolete complexity:

    - `internal` was no longer ever set to True
      by real code, so we kill it off as well
      as well as killing off the internal_blurb code
      and the now-obsolete test

    - the `sender` parameter was actually an
      email, not a UserProfile, but I think
      that got past mypy due to the caller
      passing in something from settings.py

    - we were only passing in NOTIFICATION_BOT
      for the sender, so we just hard code
      that now

    - we eliminate the verbose
      `admin_realm_signup_notifications_stream`
      parameter and just hard code it to
      "signups"

    - we weren't using the optional realm
      parameter

There's also a long ugly comment in
`get_recipient_info` related to this code
that I amended for now.
We should try to take action in a subsequent
commit.

This applies rate limiting (through a decorator) of authenticate()

The limiting is based on the username that the authentication is
attempted for - more than X attempts in Y minutes to a username is not
permitted.

If the limit is exceeded, RateLimited exception will be raised - this
can be either handled in a custom way by the code that calls
authenticate(), or it will be handled by RateLimitMiddleware and return

Tim Abbott 05108760f6 narrow: Add support for passing oldest/newest for anchor.
A wart that has long been present inin Zulip's get_messages API is how
to request "the latest messages" in the API.  Previously, the
recommendation was basically to pass anchor=10000000000000000 (for an
appropriately huge number). An accident of the server's implementation
meant that specific number of 0s was actually important to avoid a
buggy (or at least wasteful) value of found_newest=False if the query
had specified num_after=0 (since we didn't check).

This was the cause of the mobile issue
https://github.com/zulip/zulip-mobile/issues/3654.

The solution is to allow passing a special value of anchor='newest',
basically a special string-type value that the server can interpret as
meaning the user precisely just wants the most recent messages.  We
also add an analogous anchor='oldest' or similar to avoid folks
needing to write a somewhat ugly anchor=0 for fetching the very first
messages.

We may want to also replace the use_first_unread_anchor argument to be
a "first_unread" value for the anchor parameter.

While it's not always ideal to make a value have a variable type like
this, in this case it seems like a really clean way to express the
idea of what the user is asking for in the API.

Tim Abbott e2810d7549 narrow: Fix server handling of other larger anchor values.
This fixes a bug where that clients using the legacy approach of a
"very large anchor" value with the intent to only get the most recent
messages would only get found_newest=True if they used the specific
value LARGER_THAN_MAX_MESSAGE_ID.  Now any value at least that large
will work.

In upcoming commits, we plan to replace this with passing the string
"last", but it seems worth removing the buggy "special value" behavior
while we're touching this code.

Tim Abbott c0712431df openapi: Add hacky support for oneOf parameter types.
This is required for the upcoming type behavior of the "anchor"
parameter.

This change is the minimal work required to have our OpenAPI code not
fail when checking a union-type value of this form.  We'll likely want
to, in the future, do something nicer, but it'd require more extensive
infrastructure for parsing of OpenAPI data that it's worth with our
current approach (we may want to switch to using a library).

Rohitt Vashishtha 630c564fc7 bugdown: Rewrite List Preprocessor logic to properly parse fences.
Previously, we didn't track opening and closing fences separately,
with led to bugs like not parsing a list that was immediately after
a quoted fence; we treated each ``` as a new fence.

This commit rewrites the function to maintain a stack of currently
open fences. If any of the parent fences is a code fence, we do not
insert a new line before a list.

We also add some test cases specifically to test this behavior with
complexly nested lists.

Fixes #13745.

Hashir Sarwar 13b3eb24b0 invitations: Avoid adding to notifications stream unconditionally.
Adding invited users to the notifications stream unconditionally isn't
a correct behaviour for guest users, where the previous behavior of
including the notifications stream no longer makes sense. Therefore,
while inviting a new user, the notifications stream is listed along
with other streams with a message "recieves notifications for new
streams" in order to distinguish it from other streams.

Fixes #13645.

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.

This legacy cross-realm bot hasn't been used in several years, as far

as an embedded bot using those common APIs, rather than the totally
custom hacky code used for it that involves unnecessary queue workers
and similar details.

None if user isn't found.

Tim Abbott e052ec58db slack import: Improve error messages around invalid tokens.
This updates our error handling of invalid Slack API tokens (and other
networking error handling) to mostly make sense:
* A token that doesn't start with `xoxp-` gives an extended error early.
* An AssertionError for the codebase is correctly declared as such.
* We check for token shape errors before querying the Slack API.

We could still do useful work to raise custom exception classes here.

Mateusz Mandera 8dd95bd057 tests: Replace httpretty with responses.
responses is an module analogous to httpretty for mocking external
URLs, with a very similar interface (potentially cleaner in that it
makes use of context managers).

The most important (in the moment) problem with httpretty is that it
breaks the ability to use redis in parts of code where httpretty is
enabled.  From more research, the module in general has tendency to
have various troublesome bugs with breaking URLs that it shouldn't be
affecting, caused by it working at the socket interface layer.  While
those issues could be fixed, responses seems to be less buggy (based
on both third-party reports like ckan/ckan#4755 and our own experience
in removing workarounds for bugs in httpretty) and is more actively
maintained.

Mateusz Mandera d37e6ef921 email_mirror: Use plaintext if html body empty with prefer-html option.
If an email is sent with the .prefer-html option, but it has no html

it as a user error.

Mateusz Mandera 0c9c218e91 email_mirror: Add prefer-html and prefer-text address options.
Closes #13484.

These options tell zulip whether to prefer the plaintext or html version
of the email message. prefer-text is the default behavior, so including
the option doesn't change anything as of now, but we're adding it to
prepare to potentially change the default behavior in the future.

Tim Abbott 8ff5d8ca89 test_classes: Clean up API_KEYS cache.
Since the intent of our testing code was clearly to clear this cache
for every test, there's no reason for it to be a module-level global.

This allows us to remove an unnecessary import from test_runner.py,
which in combination with DEFAULT_REALM's definition was causing us to
run models code before running migrations inside test-backend.

(That bug, in turn, caused test-backend's check for whether migrations
needs to be run to happen sadly after trying to access a Realm,
trigger a test-backend crash if the Realm model had changed since the
last provision).

Anders Kaseorg ea6934c26d dependencies: Remove WebSockets system for sending messages.
Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013.  We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not.  Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.

While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.

This WebSockets code path had a lot of downsides/complexity,
including:

* The messy hack involving constructing an emulated request object to
  hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
  needs and must be provisioned independently from the rest of the
  server).
* A duplicate check_send_receive_time Nagios test specific to
  WebSockets.
* The requirement for users to have their firewalls/NATs allow
  WebSocket connections, and a setting to disable them for networks
  where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
  been poorly maintained, and periodically throws random JavaScript
  exceptions in our production environments without a deep enough
  traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
  server restart, and especially for large installations like
  zulipchat.com, resulting in extra delay before messages can be sent
  again.

As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients.  We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.

If we later want WebSockets, we’ll likely want to just use Django
Channels.

Mateusz Mandera 0beae44081 email_mirror: Use .walk() to search all MIME parts for attachments.

We used to search only one level in depth through the MIME structure,
and thus would miss attachments that were nested deeper (which can
happen with some email clients). We can take advantage of message.walk()
to iterate through each MIME part.

Tlazypanda 30ee0c2a49 invitations: Improve experience around reactivating users.
Previously, if you tried to invite a user whose account had been
deactivated, we didn't provide a clear path forward for reactivating
the users, which was confusing.

We fix this by plumbing through to the frontend the information that
there is an existing user account with that email address in this
organization, but that it's deactivated.  For administrators, we
provide a link for how to reactivate the user.
