Mateusz Mandera 716449030d emails: Rename missed message email sender to "Zulip notifcations".
It was decided that this is more appropriate naming. "Missed message"
gives it a bit of a sound like something went wrong.

Tim Abbott a1cfe25f8d streams: Move can_access_stream_user_ids into streams.py.
This belongs either here or in stream_subscription.py, which arguably

Tim Abbott e4932bd952 actions: Fixed deactivated user IDs being included for stream events.
This was a mostly harmless bug, since those users cannot have active
clients, but fixing it will improve performance in any Zulip
organization where the vast majority of users are deactivated.

akshatdalton 6509c4f8f4 linkifiers: Add an API to support the editing of linkifier.
This commit adds an API to `zproject/urls.py` to edit/update
the realm linkifier. Its helper function to update the
database is added in `zerver/lib/actions.py`.

`zulip.yaml` is documented accordingly as well, clearly
stating that this API updates one linkifier at a time.

The tests are added for the API and helper function which
updates the realm linkifier.

Fixes #10830.

Mateusz Mandera 68d1f2d7ef streams: Add realm check in can_access_stream_history.
The caller is supposed validate the stream and user realm match, but
since this is a security-sensitive function, we should have this
defensive code to protect against some validation bugs in the caller
leading to this being called incorrectly and returning True.

Mateusz Mandera 4e26a9e9d6 subs: Fix codepaths incorrectly fetching subs of deactivated users.
Fixes #17922.

These two places fetch subscriptions for the sake of getting user ids to
send events to. Clearly deactivated users should be excluded from that.
2021-04-19 10:10:51 -07:00
Mateusz Mandera 50bfbb588e subs: Allow filtering by is_user_active in get_active_subscriptions.
get_active_subscriptions_for_stream_id should allow specifying whether
subscriptions of deactivated users should be included in the result.
Active subs of deactivated users are  a subtlety that's easy to miss
when writing relevant code, so we make include_deactivated_users a
mandatory kwarg - this will force callers to definitely give thought to
whether such subs should be included or not.

This commit is just a refactoring, we keep original behavior everywhere
- there are places where subs of deactivates users should probably be
excluded but aren't - we don't fix that here, it'll be addressed in
follow-up commits.

Mateusz Mandera c3a8a15bae delete_messages: Pass a list of user ids in the event in all cases.
The bulk deletion codepath was using dicts instead of user ids in the
event, as opposed to the other codepath which was adjusted to pass just
user ids before. We make the bulk codepath consistent with the other
one. Due to the dict-type events happening in 3.*, we move the goal for
deleting the compat code in process_notification to 5.0.

Mateusz Mandera 6e11754642 CVE-2021-30478: Prevent API super users from forging messages to other organizations.
A bug in the implementation of the can_forge_sender permission
(previously is_api_super_user) resulted in users with this permission
being able to send messages appearing as if sent by a system bots,
including to other organizations hosted by the same Zulip installation.

- The send message API had a bug allowing an api super user to
  use forging to send messages to other realms' streams, as a
  cross-realm bot. We fix this most directly by eliminating the
  realm_str parameter - it is not necessary for any valid current use
  case. The email gateway doesn't use this API despite the comment in
  that block suggesting otherwise.
- The conditionals inside access_stream_for_send_message are changed up
  to improve security. They were generally not ordered very well,
  allowing the function to successfully return due to very weak
  acceptance conditions - skipping the higher importance checks that
  should lead to raising an error.
- The query count in test_subs is decreased because
  access_stream_for_send_message returns earlier when doing its check
  for a cross-realm bot sender - some subscription checking queries are
  skipped.
- A linkifier test in test_message_dict needs to be changed. It didn't
  make much sense in the first place, because it was creating a message
  by a normal user, to a stream outside of the user's realm. That
  shouldn't even be allowed.

Mateusz Mandera 4235be759d CVE-2021-30477: Prevent outgoing webhook bots from sending arbitrary messages to any stream.
A bug in the implementation of replies to messages sent by outgoing
webhooks to private streams meant that an outgoing webhook bot could be
used to send messages to private streams that the user was not intended
to be able to send messages to.

Completely skipping stream access check in check_message whenever the
sender is an outgoing webhook bot is insecure, as it might allow someone
with access to the bot's API key to send arbitrary messages to all
streams in the organization. The check is only meant to be bypassed in
send_response_message, where the stream message is only being sent
because someone mentioned the bot in that stream (and thus the bot
posting there is the desired outcome). We get much better control over
what's going by passing an explicit argument to check_message when
skipping the access check is desirable.

sahil839 685fbffd91 tests: Refactor check_has_permission_policies to check for all user roles.
We refactor check_has_permission_policies to check for all user roles for
each value of policy. This will help in handle a case where a guest is
allowed to do something but moderator isn't.

We need to do user_profile.refresh_from_db() in validation_func because
the realm object from user_profile is used in has_permission and we need
updated realm instance after changing the policy.

Abhijeet Prasad Bodas 3947b0c80a linkifiers: Update API to send data using dictionaries.
* This introduces a new event type `realm_linkifiers` and
a new key for the initial data fetch of the same name.
Newer clients will be expected to use these.

* Backwards compatibility is ensured by changing neither
the current event nor the /register key. The data which
these hold is the same as before, but internally, it is
generated by processing the `realm_linkifiers` data.
We send both the old and the new event types to clients
whenever the linkifiers are changed.
Older clients will simply ignore the new event type, and
vice versa.

* The `realm/filters:GET` endpoint (which returns tuples)
is currently used by none of the official Zulip clients.
This commit replaces it with `realm/linkifiers:GET` which
returns data in the new dictionary format.
TODO: Update the `get_realm_filters` method in the API
bindings, to hit this new URL instead of the old one.

* This also updates the webapp frontend to use the newer
events and keys.

Tim Abbott 2e928a0853 markdown: Remove logic for creating markdown engines for all realms.
This logic likely never ran due to a combination of bugs.

* Running `maybe_update_markdown_engines` unconditionally meant that
  `if md_engine_key in md_engines` was likely always true.
* Introduced in 65838bb: DEFAULT_MARKDOWN_KEY could never be in
  md_engines, so should we have ever reached that code path, we'd have
  tried to rebuild all markdown engines every time.

And it also wasn't clearly helpful -- because we fetch all linkifiers
for a realm on every request anyway, we don't really save database
queries by doing a bulk fetch on startup, and doing so would likely
result in a material regression to Zulip's overall startup time that
we were creating markdown engines for large numbers of realms in bulk
during process startup.

Abhijeet Prasad Bodas 2b9f2cc8ff mute user: Add some comments on message fetch.
These explain why we don't consider user mutes
in message fetching/unread data.
2021-04-13 09:15:49 -07:00
Abhijeet Prasad Bodas 8b098b95bb mute user: Mark as read old messages immediately.
When a user is muted, in the same request,
we mark any existing unreads from that user
as read.

This is done for all types of messages
(PM/huddle/stream) and regardless of whether
the user was mentioned in them.

This will not break the unread count logic
of the web frontend, because that algorithm
decides which messages to mark as read based
only on the pointer location and the whitespace
at the bottom, not on what messages have already
been marked as read.
2021-04-13 09:08:47 -07:00
Abhijeet Prasad Bodas 2f56f8d0ed mute user: Mark as read new messages.
Messages sent by muted users are marked as read
as soon as they are sent (or, more accurately,
while creating the database entries itself), regardless
of type (stream/huddle/PM).

ede73ee4cd, makes it easy to
pass a list to `do_send_messages` containing user-ids for
whom the message should be marked as read.
We add the contents of this list to the set of muter IDs,
and then pass it on to `create_user_messages`.

This benefits from the caching behaviour of `get_muting_users`
and should not cause performance issues long term.

The consequence is that messages sent by muted users will
not contribute to unread counts and notifications.

This commit does not affect the unread messages
(if any) present just before muting, but only handles
subsequent messages. Old unreads will be handled in
further commits.
2021-04-13 09:08:47 -07:00
Abhijeet Prasad Bodas b140c17441 mute user: Cache list of muter IDs.
This commit defines a new function `get_muting_users`
which will return a list of IDs of users who have muted
a given user.
Whenever someone mutes/unmutes  a user, the cache will be
flushed, and subsequently when that user sends a message,
the cache will be populated with the list of people who
have muted them (maybe empty).

This data is a good candidate for caching because-

1. The function will later be called from the message send
codepath, and we try to minimize database queries there.

2. The entries will be pretty tiny.

3. The entries won't churn too much. An average user will
send messages much more frequently than get muted/unmuted,
and the first time penalty of hitting the db and populating
the cache should ideally get amortized by avoiding several
DB lookups on subsequent message sends.

The actual code to call this function will be written in
further commits.
2021-04-13 09:08:47 -07:00
Abhijeet Prasad Bodas 9602aa1467 mute user: Record entries in RealmAuditLog.
This makes it so that RealmAuditLog entries are
created when a user mutes/unmutes someone.

We don't really need to store the time, but we
do so anyways, because the `event_time` field
is currently a non-nullable one in the `RealmAuditLog`
model, and making it nullable would risk allowing
not specifying the time in other more important
code which also creates `RealmAuditLog` entries.

This also fixes an incorrect test of successfully
unmuting with the API. Earlier it did not mock
the time in the `views/muting.py` code to return
`mute_time`.

api: Add max_message_length field to API data.
Commit 4a3ad0d introduced some extra stream-level parameters
to the `realm` object. This commit extends that to add a
max_message_length paramter too in the same server_level.
2021-04-12 16:03:31 -07:00
Tim Abbott 4a3ad0da06 api: Improve encoding of stream/topic max field lengths.
Previously, you had to request the `stream` event type in order to get
the stream-level parameters; this was a bad design in part because the
`subscription` event type has similar data and is preferred by most
clients.

So we move these to the `realm` object.  We also add the maximum topic
length, as an adjacent parameter.

While changing this, we also fix these to better match the names of
similar API parameters.
2021-04-10 10:07:57 -07:00
Abhijeet Prasad Bodas 152508e346 mute user: Reduce two database fetches when unmuting to one.
Previously, when unmuting a user, we used to make
two database fetches - one to verify that the user
is has been muted before, and one while actually
unmuting the user.

This reduces that to one, by passing around the
`MutedUser` object fetched in the first round.

Since the new function returns `Optional[MutedUser]`,
we need to use a hack for events tests, because
mypy does not yet use the type inferred from
`assert foo is not None` in nested functions like lambdas.
See python/mypy@8780d45507.

sahil839 1ffcb0f8b9 streams: Raise same error for all values of create_stream_policy.
We keep the error message same for all cases when a user is not

we do not show errors probably in API only, as we do not the show

Sumanth V Rao 1ac8fe7538 events/tests/api: Send realm_playground events to clients.
We send the whole data set as a part of the event rather than
doing an add/remove operation for couple of reasons:
    * This would make the client logic simpler.
    * The playground data is small enough for us to not worry
      about performance.

Tweaked both `fetch_initial_state_data` and `apply_events` to
handle the new playground event.

Tests added to validate the event matches the expected schema.

Documented realm_playgrounds sections inside /events and
/register to support our openapi validation system in test_events.

Tweaked other tests like test_event_system.py and test_home.py
to account for the new event being generated.

Lastly, documented the changes to the API endpoints in
api/changelog.md and bumped API_FEATURE_LEVEL.

Abhijeet Prasad Bodas 3bfcaa3968 mute user: Add backend infrastructure code.
Adds backend code for the mute users feature.
This is just infrastructure work (database
interactions, helpers, tests, events, API docs
etc) and does not involve any behavioral/semantic
aspects of muted users.

Adds POST and DELETE endpoints, to keep the
URL scheme mostly consistent in terms of `users/me`.

TODOs:
1. Add tests for exporting `zulip_muteduser` database table.
2. Add dedicated methods to python-zulip-api to be used
   in place of the current `client.call_endpoint` implementation.

LoopThrough-i-j ffd0d822fe actions: Send reaction events to subscribers with history access.
Previously, if a user subscribed to a stream with
history_public_to_subscribers, and then was looking at old messages in
the stream, they would not get live-updates for that stream, because
of the structure in how notify_reaction_update only looked at
UserMessage rows (we had a previous workaround involving the
`historical` field in `UserMessage` which had already made it work if
the user themselves added the reaction).

We fix this by including all subscribers with history access in the
set of recipients for update events.

Fixes a bug that was confused with #16942.

Cyril Pletinckx b7fa41601d emails: Truncate overly-long From fields for RFC compatibility.
Amazon SES has a limit on the size of address fields, and rejects
emails with too-long "From" combinations of name and address. This
limit is set to 320 bytes and comes from an RFC limitation on the
size of addresses. This RFC standard states that an email address
should not be composed of a local part (before the '@') longer than
64 bytes and a domain part (after the '@') longer than 255 bytes.
It is possible that Amazon SES misinterprets this limitation as it
checks the length of the combination of the name and the email
address of the sender.

To ensure that this problem is not encountered in the send_email
module of Zulip the length of this combination is now checked
against this limit and the from_name field is removed to only
keep the from_address field when it is necessary in order to
stay below 320 bytes.

If the from_address field alone is longer than 320 bytes the
sending process will raise an SMTPDataError exception.

Tests for this new check are added to the backend test suite in
order to test if build_email correctly outputs an email with filled
from_name and from_address fields when the total length is lower
than 320 bytes and that it correctly throws the from_name field
away when necessary.

Fixes: #17558.

WookieMonkeys 1b6f68bb59 stream: Add entropy to deactivated streams.
Adding an additional `!` to the stream name each time a stream is
deactivated, to a maximum of 21 times, effectively limits number of
times a stream with a given name can be deactivated.  This is unlikely
to come up in common usage, but may be confusing when testing.

Change what we prepend to deactivated stream names to something with
more entropy than just `!`, by instead prepending a substring of hash
of the stream's ID.  `!`s.  Using 128 bits of the hash means that it
will require more than 10^18th renames to have a 1% chance of collision.

Because too-long stream names are also truncated at 60 characters,
having this entropy in the beginning of the name also helps address
potential issues from stream names that differed only in, e.g. the
60th character.

Fixes #17016.

m-e-l-u-h-a-n aea31eb31f api: Add REALM_DEACTIVATED error code.
In `validate_account_and_subdomain` we check
if user's realm is not deactivated. In case
of failure of this check, we raise our standard

cases but it creates difficulties in handling
of users with deactivated realms for non-browser
clients.

So we register a new REALM_DEACTIVATED error
code so that clients can distinguish if error
is because of deactivated account. Following
these changes `validate_account_and_subdomain`

is deactivated.

m-e-l-u-h-a-n 1b8a5a3344 markdown: Refactor backend logic for handling user mention.
Backend logic for handling user mention was cluttered
because it was handled at two stages first in
get_possible_mentions_info while fetching mention data
based on the messsage and then later in UserMentionPattern
which handles processing of text for mention.

Ideally UserMentionPattern should depend on
get_possible_mentions_info only for data but there was a
shared logic between these two that made it hard to debug
any possible bugs.

Updates in this commit make both of these functions
coherent in terms of logic and also add appropiate
comments to improve readability of these functions.

There was also a hidden bug that if a user A is
mentioned in with @**name|id** then @**invalid|id**
again mentioned A because of the way we handled mentions
earlier. It is solved as a result of this refactor and
appropiate test has been added for this.

This has been tested manually as well as by adding new
test to address missing case.

Tim Abbott 96c61a1a41 events: Fix broken custom_profile_fields events logic.
I noticed this because the test_events.py tests had the extremely
weird pattern of calling the actual change function, and then testing
the `notify` function's state changes (which should always be noops),
rather than actually testing the state change function.

Fixing the test made it clear that the actual logic in events.py
simply did not handle deleting custom_profile_field_value elements
from user objects when a custom_profile_field object was deleted.

So we fix that bit of logic as well.

It appears this bug was unique -- at least we don't have any other
notify_* functions being used directly in test_events.py, and the
handful of state_change_expected=False entries are all events for data
not present in page_params.

We discovered recently that some ops for events were just not
implemented in events.py (specifically, realm/deactivated).

Since our goal is for events.py to be complete, we add this bit of
hardening to ensure that it stays that way.

m-e-l-u-h-a-n 830c4acedc markdown: Fix invalid mention bug for stream and stream topic mention.
Modifies `StreamPattern` and `StreamTopicPattern` to inherit
from InlineProcessor instead of Pattern. This change is done
because Pattern stopped checking for matching patterns as soon
as it found a match which was not a valid stream. Due to this
all the subsequent mention failed, even if they were valid.
This bug was only present in backend renderring due to
markdown.inlinepatterns.Pattern.

Due to above changes verbose_compile is no longer used for
precompiling STREAM_LINK_REGEX, STREAM_TOPIC_LINK_REGEX as
adds ^(.*?) and (.*?)$ which cause extra overhead of matching
pattern which is not required. With new InlineProcessor these
extra patterns at beggining and end are not required.
So, StreamPattern and StreamTopicPattern now define their own
__init__ method for precompiling the regex.

Fixes #17535.

These changes were tested locally in dev server and by adding
some new markdown tests to test these.

Mateusz Mandera 90636d5e81 events: Fix bug in get_recent_conversations_recipient_id.
user_profile.id was confused for user_profile.recipient_id. These bugs
are particularly sneaky as they can go undetected by tests due to ids of
objects accidentally coinciding. We add a mitigation for this class of
mistakes by shifting the Recipient.id sequence in test db.

This was introduced in dda3ff41e1.
On the rare occasion where user_profile.id would coincide with
recipient_id passed to the function, we would return the wrong value.
That is, instead of correctly returning recipient_id, we would return
sender.recipient_id - recipient id of the sender of the message, thus
possibly returning user_profile.recipient_id (if user_profile is the
sender) - exactly the situation the function wanted to avoid
with the `if recipient_id == my_recipient_id:` if. Ultimately resulting
in incorrect/malformed data in
state['raw_recent_private_conversations'].

m-e-l-u-h-a-n 0e6343c071 users: Clarify readability issues related to access_user_by_id.
zerver/lib/users.py has a function named access_user_by_id, which is
used in /users views to fetch a user by it's id. Along with fetching
the user this function also does important validations regarding
checking of required permissions for fetching the target user.

In an attempt to solve the above problem this commit introduces
following changes:
1. Make all the parameters except user_profile, target_user_id
   to be keyword only.
2. Use for_admin parameter instead of read_only.
3. Adds a documentary note to the function describing the reason for
   changes along with recommended way to call this function in future.
4. Changes in views and tests to call this function in this changed
   format.

Steve Howell 1498b2ef69 apply_event: Fix broken deepcopy attempt for subs.
When we were getting an apply_event call for
a subscription/add event, we were trying not to
mutate the event itself, but this clumsy code
was still mutating the actual event:

    # Avoid letting 'subscribers' entries end up in the list
    for i, sub in enumerate(event['subscriptions']):
        event['subscriptions'][i] = \
            copy.deepcopy(event['subscriptions'][i])
        del event['subscriptions'][i]['subscribers']

This is only a theoretical bug.

The only person who receives a subscription/add
event is the current user.

And it wouldn't have affected the current user,
since the apply_event was correctly updating the
state, and we wouldn't actually deliver the event
to the client (because the whole point of apply_event
is to prevent us from having to piggyback the
super-recent events on to our payload or put
them into the event queue and possibly race).

The new code just cleanly makes a copy of each
sub, if necessary, as we add them to state["subscriptions"].

And I updated the event schemas to reflect that
subscribers is always present in subscription/add
event.

Long term we should probably avoid sending subscribers
on this event when the clients don't set something
like include_subscribers.  That's a fairly complicated
fix that involves passing in flags to ClientDescriptor.
Alternatively, we could just say that our policy is
that we never send subscribers there, but we instead
use peer_add events.  See issue #17089 for more
details.

Steve Howell c6acde9c63 apply_event: Use stream_ids, not names, for add/remove.
It's always cleaner to work in id space.  It probably

robust in theory, and just as simple.

Steve Howell 3fa595ef85 minor: Clean up args for apply_event.
We now require keywords, so that there is no

Positional parameters are basically evil
when you have a bunch of bools.

I also make user_profile the first argument.

Finally, the code is more diff-friendly.

Steve Howell e42baf9e13 minor: Clean up args for apply_events.
I eliminate the defaults, since the existing code
was already specificying values for most things.

I move all the booleans to the bottom for both
parameters and arguments.

I require explicit keywords for everything but
user_profile (which is now first).

And, finally, I format the code in a more
diff-friendly manner.

2021-01-21 15:04:07 -08:00
Steve Howell d9740045a5 refactor: Eliminate checks in build_stream_dict_for_sub.
We eliminate some redundant checks.

We also consistently provide a `subscribers` field
in our stream data with `[]`, even if our users
can't access subscribers.  We therefore bump
the API version and tweak the docs.  (See further
down for a detailed justification of the change.)

Even though it is sometimes fine to have redundant code
that is defensive in nature, some upcoming changes are gonna
move subscriber-related logic out of build_stream_dict_for_sub
for certain codepaths as part of our effort to streamline
the payload for subscribers within page_params.

So we can't rely on the code that I removed here
inside of build_stream_dict_for_sub.

Anyway, it makes more sense to do these checks explicitly
in the validate function.

The code in build_stream_dict_for_sub was almost effectively
a noop, since the validation function was already preventing
us from getting subscriber info.  The only difference it
made was sometimes converting `[]` to `None`, and then
subsequently omitting the subscribers field.

Neither ZT nor the webapp make any distinction between
`[]` or <missing key> for the `subscribers` data in
`page_params`.

The webapp has had this code for a long time (and now
equivalent code elsewhere in this PR):

    if (!Object.prototype.hasOwnProperty.call(sub, "subscribers")) {
        sub.subscribers = new LazySet([]);
    }

The webapp calculates access based on booleans, anyway:

    sub.can_access_subscribers =
        page_params.is_admin || sub.subscribed ||
        (!page_params.is_guest && !sub.invite_only);

And ZT would choke if `subscribers` were missing, except that
it never gets to the relevant code due to other checks:

    def get_other_subscribers_in_stream(<snip>):
        assert stream_id is not None or stream_name is not None

        if stream_id:
            assert self.is_user_subscribed_to_stream(stream_id)

            return [sub
                    for sub in self.stream_dict[stream_id]['subscribers']
                    if sub != self.user_id]
        else:
            return [sub
                    for _, stream in self.stream_dict.items()
                    for sub in stream['subscribers']
                    if stream['name'] == stream_name
                    if sub != self.user_id]

You could make a semantic argument that we should prefer
<missing key> to `[]` when subscribers aren't even available, but
we have precedent from the way that `bulk_get_subscriber_user_ids`
has traditionally populated its result:

    result: Dict[int, List[int]] =
        {stream["id"]: [] for stream in stream_dicts}

If we changed `stream_dicts` to `target_stream_dicts` we
would faciliate a move toward `None`, but it would just cause
headaches for other server code as well as the frontends
(which, to reiterate, already prefer the empty array
for convenience).

Steve Howell 40b0c36d21 minor: Update comment for guest subscription access.
As my comment indicates, I would prefer to handle

bit of work, mostly on the testing side to make
sure we are covering all edge cases, but that
is out of the scope of my current PR.

This makes us more efficient when handling

Note that as part of this we eliminated
a failure mode for the obscure population
of users from whom both `user.is_guest` and
`user.can_access_public_streams()` returns
False.  We know this would have only affected
Zephyr users (by looking at the code), and
we know we don't actually process Zephyr
users for email digests (or else we would
have raised exceptions in the old code).

Mateusz Mandera 3623681d30 message_edit: Don't rely on .recipient_id change not affecting recipient.
The codepath for moving a topic changes the message.recipient_id to the
id of the new recipient, but later, in update_messages_for_topic_edit,
it uses message.recipient when querying for messages with the matching
topic in the *old* stream (because those are the other messages that
need to be moved). This is a bug which happens to work fine, because in
Django 2, if message.recipient gets fetched first and then
message.recipient_id is mutated, message.recipient will not be altered
and thus will retain the outdated, previously fetched value.

In Django 3 changing .recipient_id causes .recipient to be updated to
the new Recipient objects, which is the Recipient of the *new* stream.
That will cause the bug to manifest.

This is a bugfix preparing for the upgrade to Django 3.

Siddharth Asthana 6c888977a6 change_subdomain: Create a deactivated realm on updating subdomain.
When changing the subdomain of a realm, create a deactivated realm with
the old subdomain of the realm, and set its deactivated_redirect to the
new subdomain.
Doing this will help us to do the following:
- When a user visits the old subdomain of a realm, we can tell the user
that the realm has been moved.
- During the registration process, we can assure that the old subdomain
of the realm is not used to create a new realm.

If the subdomain is changed multiple times, the deactivated_redirect
fields of all the deactivated realms are updated to point to the new
uri.

sahil839 2fa33be683 actions: Refactor check_message to change return dataclass instead of Dict.
We change the return type of check_message to be dataclass instead of
Dict[str, Any]. This refactoring helps us to understand the context of the
data structure returned by check_message clearly which was not possible
when using Dict.

SendMessageRequest class is added in zerver/lib/message.py inspite of it
not being used in that file itself just to maintain consistency as other
TypedDicts and dataclasses are defined in that file and to avoid circular
dependency as SendMessageRequest is being used in lib/widget.py as well.

We also rename local variable to 'send_request' for accessing
SendMessageRequest objects.

sahil839 37c8505435 message: Raise exception when trying to mirror an already sent message.
Previously we were just returning a dict containing a message id when
trying to mirror a already sent message in 'zephyr_mirror' cases.

This commit changes this behaviour to raise an exception when trying
to mirror an already sent message by adding a new exception class
ZephyrMessageAlreadySentException and then the caller returns the
message_id directly, instead of calling do_send_messages which also
returns a list of size one containing the message_id only.

This is a prep commit for changing the return type of check_message to
be a dataclass instead of a Dict as now we have only single output for
check_message.

sahil839 4e99ec34a9 widget: Use different variable names for message and submessage content.
This commit renames the content variable in do_widget_post_save_actions
to message_content and is a prep commit for changing the return type of
check_message from Dict to dataclass.

This change is required because content variable is used two times in
this function - one for message content and other for submessage
content, so when we change the return type of check_message to
dataclass, the type of content variable is considered as str and then
when dict is assigned to content in the submessage case, mypy raises
'Incompatible types in assignment' error.

This issue is not faced before the dataclass migration because there is
no type checking for the values of dict returned by check_message as the
return type of check_message is 'Dict[str, Any]'.
