Tim Abbott 47c85fa02e email: Set email based on realm email_address_visibility.
This causes changing the email_address_visibility field to actually
modify what user_profile.email values are generated for users, both on
user creation and afterwards as email addresses are edited.

The overall feature isn't yet complete, but this brings us pretty close.

Hemanth V. Alluri 73d26c8b28 streams: Render and store the stream description from the backend.
This commit does the following three things:
    1. Update stream model to accomodate rendered description.
    2. Render and save the stream rendered description on update.
    3. Render and save stream descriptions on creation.

Further, the stream's rendered description is also sent whenever the
stream's description is being sent.

This is preparatory work for eliminating the use of the
non-authoritative marked.js markdown parser for stream descriptions.

Eeshan Garg f4221f2655 internal_prep_message: Don't call ensure_stream for stream IDs.
Ever since we implemented support for stream IDs in Addressee,
Addressee.stream_name() can now return None. This commit ensures
that _internal_prep_message only calls ensure_stream when
Addressee.stream_name() is not None.

Eeshan Garg 998437c123 check_message: Support sending stream messages by ID.
This commit also contains the following auxiliary changes:
* Adds a custom exception, StreamWithIDDoesNotExist for when
  a stream with a given ID does not exist because the error
  message returned by StreamDoesNotExist only makes with stream
  names, not IDs.
* Adds a new helper, get_stream_by_id_in_realm, which is similar
  to get_user_profile_by_id_in_realm (introduced in #10391).
* Adds a helper, validate_stream_id_with_pm_notification, which
  returns the Stream object associated with a given ID and also
  handles PM notifications to the bot owner if the message was
  sent by a bot and if the stream does not exist or has no
  subscribers.
* Modifies the message sent by send_pm_if_empty_stream to
  accommodate stream IDs.

Note that all of the above changes are required before check_message
can be modified to support stream IDs.

Steve Howell 0ef5d1f9c8 user status: Add "status_text" support in the backend.
You can now pass in an info field with a value
like "out to lunch" to the /users/me/status,
and the server will include that in its outbound
events.

The semantics here are that both "away" and
"status_text" have to have defined values in order
to cause changes.  You can omit the keys or
pass in None when values don't change.

The way you clear info is to pass the empty
string.

We also change page_params to have a dictionary
called "user_status" instead of a set of user
ids.  This requires a few small changes on the
frontend.  (We will add "status_text" support in
subsequent commits; the changes here just keep
the "away" feature working correctly.)

Steve Howell ac861f2b7d user status: Restructure code.
We now have single function that handle both away
and not-away.

This refactoring sets us up to piggyback "info" more
easily onto status updates.

The only thing that changes here is that we don't
delete database rows any more when users revoke
their away status.  Instead we just set the status
to NORMAL.

Hemanth V. Alluri 716bcad393 custom profile fields: Extract check_remove_user_custom_profile_value.
This moves the logic for deleting the user's custom profile field
value in the remove_user_custom_profile_data view function to a method
named check_remove_user_custom_profile_value in actions.py, so that we
can reuse it in the next commit.

Aditya Bansal 4e4c33fee2 reminders: Make reminders setup work only for Streams.
We make this change because setting up reminders in PM's didn't
play really well with our current infrastructure. Basically the
reminder messages from the bot can't appear in the same narrow as
that of a PM between two people and therefore we disable it.
Though we make an exception here where a person wants to set up
reminder for himself.

Eeshan Garg 020f2d0db5 send_message_backend: Add support for recipient user IDs.

Eeshan Garg b3e8e36a8d messages: Check for empty recipient lists in Addressee.
The check for empty recipient lists (the "message_to" argument)
does not belong in check_message. As we implement support for
sending messages by user IDs (see #9474), we will be extending
much of the existing code in Addressee.legacy_build that validates
recipient lists. Therefore, Addressee.legacy_build is a much more
apt area to check for empty recipient lists.

Also, Addressee.for_private and Addressee.for_user_ids also need
to do their own validation, since not everything goes through
Addressee.legacy_build. It is okay to simply throw a 500 in these
cases because we expect that callers will be doing their own
validation for calls that don't go through Addressee.legacy_build().

This commit is a part of our efforts surrounding #9474.

Shubham Dhama 42c262b807 invite: Replace `invite_as_admin` usage with `invite_as`.
Since we have already added the `invite_as` field to models, we can now

== PreregistrationUser.INVITE_AS['REALM_ADMIN']`.

Hence, also removed now redundant `invite_as`.

Tweaked significantly by tabbott to rebase, fix styling, etc.

Fixing the styling of this feature's loading indicator caused me to
notice the loading indicator for the realm_icon feature was also ugly,
so I fixed that too.

Tim Abbott b2fc017671 i18n: Use the recipient's language when sending outgoing emails.
It appears that our i18n logic was only using the recipient's language
for logged-in emails, so even properly tagged for translation and
translated emails for functions like "Find my team" and "password
reset" were being always sent in English.

With great work by Vishnu Ks on the tests and the to_emails code path.

Fixes a bug in import_realm where secondary attributes like message

Also, putting the plan_type change at the end of import_realm, so that
future restrictions to LIMITED realms don't affect the import process.

Marco Burstein ba46dc83c6 notifications: Add a setting for changing the notification sound.
Also, add a new notification sound, "ding". It comes from
https://freesound.org, where the original Zulip notification sound comes
from as well. In the future, new sounds can be added by adding audio
files to the `static/audio/notification_sounds` directory.

Tweaked significantly by tabbott:
* Avoided removing static/audio/zulip.ogg, because that file is
  checked for by old versions of the desktop app.
* Added a views check for the sound being valid + tests.
* Added additional tests.
* Restructured the test_events test to be cleaner.
* Removed check_bool_or_string.
* Increased max length of notification_sound.
* Provide available_notification_sounds in events data set if global
  notifications settings are requested.

Fixes #8051.

Tim Abbott e603237010 email: Convert accounts code to use delivery_email.
A key part of this is the new helper, get_user_by_delivery_email.  Its
verbose name is important for clarity; it should help avoid blind
copy-pasting of get_user (which we'll also want to rename).
Unfortunately, it requires detailed understanding of the context to
figure out which one to use; each is used in about half of call sites.

Another important note is that this PR doesn't migrate get_user calls
in the tests except where not doing so would cause the tests to fail.
This probably deserves a follow-up refactor to avoid bugs here.

Raymond Akornor 92dc3637df send_email: Add support for multiple recipients.
This adds a function that sends provided email to all administrators
of a realm, but in a single email. As a result, send_email now takes
arguments to_user_ids and to_emails instead of to_user_id and
to_email.

We adjust other APIs to match, but note that send_future_email does
not yet support the multiple recipients model for good reasons.

Tweaked by tabbott to modify `manage.py deliver_email` to handle
backwards-compatibily for any ScheduledEmail objects already in the
database.

Tim Abbott d96624490e bulk_add_subscriptions: Fix confusing access to user_profile.realm.
Previously, we frequently accessed user_profile.realm from outside the
loops that interact with UserProfile objects.  This variable reuse
outside the loop could be confusing and should be a style/lint
violation.

While in this case, the behavior was correct (in that all users in the
loops were within the same realm), extracting a separate `realm`
variable significantly clarifies what's going on here.

Eeshan Garg 91b90460ee lib/actions: Add helper recipient_for_user_ids().
This function is equivalent to recipient_for_emails, but fetches
user_profiles by IDs, not by emails.

This commit is a part of our efforts surrounding #9474, but is
more primarily geared towards adding support for sending typing
notifications by user IDs.

Eeshan Garg 68a06abb79 actions: Stop using Addressee's helpers in recipient_for_emails.
recipient_for_emails is used by our typing notifications code.
user_profiles_from_unvalidated_emails is used by our typing
notifications code *and* for sending messages.
user_profiles_from_unvalidated_emails is a part of a larger
framework used by Addressee to validate recipient emails when sending
messages and will eventually need to be removed as we move forward
with #9474. So it makes sense to just inline this function within
recipient_for_emails so that we don't break our typing notifications
code in the future.

This commit is a part of our efforts surrounding #9474.

Steve Howell 551fc7f165 bots: Prevent bots from having duplicate full names.
Bots are not allowed to use the same name as
other users in the realm (either bot or human).

This is kind of a big commit, but I wanted to
combine the post/patch (aka add/edit) checks
into one commit, since it's a change in policy
that affects both codepaths.

A lot of the noise is in tests.  We had good
coverage on the previous code, including some places
like event testing where we were expediently
not bothering to use different names for
different bots in some longer tests.  And then
of course I test some new scenarios that are relevant
with the new policy.

There are two new functions:

    check_bot_name_available:
        very simple Django query

    check_change_bot_full_name:
        this diverges from the 3-line
        check_change_full_name, where the latter
        is still used for the "humans" use case

And then we just call those in appropriate places.

Note that there is still a loophole here
where you can get two bots with the same
name if you reactivate a bot named Fred
that was inactive when the second bot named
Fred was created.  Also, we don't attempt
to fix historical data.  So this commit
shouldn't be considered any kind of lockdown,
it's just meant to help people from
inadvertently creating two bots of the same
name where they don't intend to.  For more
context, we are continuing to allow two
human users in the same realm to have the
same full name, and our code should generally
be tolerant of that possibility.  (A good
example is our new mention syntax, which disambiguates
same-named people using ids.)

It's also worth noting that our web app client
doesn't try to scrub full_name from its payload in
situations where the user has actually only modified other
fields in the "Edit bot" UI.  Starting here
we just handle this on the server, since it's
easy to fix there, and even if we fixed it in the web
app, there's no guarantee that other clients won't be
just as brute force.  It wasn't exactly broken before,
but we'd needlessly write rows to audit tables.

Shubham Padia 6bfa29b8e6 notifications: Fix soft-deactivated users don't get push notifications.
Fixes the urgent part of #10397.

It was discovered that soft-deactivated users don't get mobile push
notifications for messages on private streams that they have configured
to send push notifications.

Reason: `handle_push_notification` calls `access_message`, and that
logic assumes that a user who is a recipient of a message has an
associated UserMessage row. Those UserMessage rows are created
lazily for soft-deactivated users, so they might not exist (yet)
until the user comes back.

Solution: Ensure that userMessage row is created for
stream_push_user_ids and stream_email_user_ids in create_user_messages.

Yashashvi Dave d5153bd136 events: Convert custom user field value to json object on update event.
In user type custom field, field value is list of user ids. We weren't
converting list to json object in update event payload. This throws
error in frontend, cause we store stringify representation of custom
field value. Therefore, after update event is recieved field-value-
type gets updated to array from string which throws json parsing error.

Shubham Dhama e784c95d97 guests: Prevent guests from sending to unsubscribed public streams.
This matches the overall security model of these users only having
access to streams they are subscribed to.

Steve Howell fe6680c316 refactor: Flatten code in check_invite_limit().
Using early-exit here allows us to more easily
comment why there are certain exemptions to
this logic.

We also only require callers to pass in realm,
not the whole user object.

Steve Howell a6bc3886e6 refactor: Extract send_peer_remove_event().
This prevents leaking some variables into an already
cluttered function.

We also add test coverage for what's now an
early-exit condition in the new function--we exempt
public MIT streams from these events.
2018-08-21 11:23:40 -07:00
Steve Howell 79fb36c599 refactor: Extract maybe_add_event() function.
This change was partially driven by a quirk in Python
where peephole optimizations make `continue` lines
appear not to be covered.

I also think it's generally a good idiom to extract
functions for loop bodies when they don't actually
accumulate values or maintain other state.  With this
commit we now prevent potential bugs for vars like
`is_stream` leaking between loop iterations.

Steve Howell e99c0929f0 tests: Test race handling for creating mirror users.
We simulate a race condition by mocking create_user
to actually create a user, but then raise an
IntegrityError (as if another process had actually
created the user, not our test).

I also changed the real code to use explicitly
named parameters.

Steve Howell 0e56fecbd9 peformance: Avoid broad StreamCount queries.
Our get_streams_traffic function used to query
all streams in the StreamCount table if you
passed in `None` for `streams`.

Now we require that you pass in a list of
stream_ids.

I don't know how much work this will save
the database, since probably the bulk of
the work is aggregating.  If we need to fine
tune DB performance, we could possibly add
`realm` as an argument and add it to the filter.

What we'll immediately get, for large multi-realm
installations, is less data over the wire and
less work for the ORM.
2018-08-17 08:14:42 -07:00
Steve Howell 040dafbfc5 refactor: Streamline subscribed_to_stream().
The prior code uses an awkward idiom that
pre-dates the `exists()` function, and it
had an unreachable line of code.

The new version should be faster, since we
don't create a throwaway heavy Django object
or send needless data over the wire.

Steve Howell c41377aaab Remove _default_stream_permision_check.
This functions appears to be redundant to
`access_stream_by_name`.  The only
meaningful line of code in the function that we're
removing, the code that raises an error,
appears to be unreachable, despite reasonably
extensive tests.

The only thing the function was restricting
was that the case where the bot's owner was
unsubscribed to a private stream, which
is already locked down in
`access_stream_by_name` calls inside of
`patch_bot_backend`.

This commit increases test coverage
by removing unreachable code.

It's possible this function had
some theoretical value before we
introduced the `require_non_guest_human_user`
decorator to the `patch_bot_backend`
view, since in theory the bot itself
could have subscribed to a stream that
the owner didn't subscribe to.  Even
then it's not clear that allowing the
bot to set that as a default stream
would have been harmful, since they
can already access it.

Steve Howell 93e8798ac7 Extract get_last_message_id().
We want our methodology for extracting the last message
id to be consistent, particularly in terms of how we
handle edge cases.  (I'll concede that the
`bulk_remove_subscriptions` codepath never hits that
corner case in practice, but it's harmless to handle
the theoretical case.)

It may also be nice to have this function show up
clearly in profiling.

This also adds some direct testing to the function.

It's not clear to me why we don't use `latest('id')`
in the implementation, but that's outside the scope
of this commit.
2018-08-17 08:14:42 -07:00
Steve Howell 9a7a93c80b refactor: Extract validate_sender_can_write_to_stream().
This de-clutters check_message a bit and also makes
it easy to audit our rules for who can write to a
stream.

Also, this works around a bug with Python where its
optimizations for the `pass` instruction make them
not appear to run and show up as uncovered in
coverage reports.

Steve Howell 413a0174f4 Extract a zephyr.py library.
Right now it only has one function, but the function
we removed never really belonged in actions.py, and
now we have better test coverage on actions.py, which
is an important module to get to 100%.
2018-08-11 14:51:26 -07:00
Steve Howell 5bc33213c9 Refactor generate_topic_history_from_db_rows.
Sorting the rows first simplifies the loop logic here.

This has good test coverage--you'll get a failing
test if you comment out the sort.

Tim Abbott da8f4bc0e9 push notifications: Add support for removing GCM push notifications.
This uses the recently introduced active_mobile_push_notification
flag; messages that have had a mobile push notification sent will have
a removal push notification sent as soon as they are marked as read.

Note that this feature is behind a setting,
SEND_REMOVE_PUSH_NOTIFICATIONS, since the notification format is not
supported by the mobile apps yet, and we want to give a grace period
before we start sending notifications that appear as (null) to
clients.  But the tracking logic to maintain the set of message IDs
with an active push notification runs unconditionally.

This is designed with at-least-once semantics; so mobile clients need
to handle the possibility that they receive duplicat requests to
remove a push notification.

We reuse the existing missedmessage_mobile_notifications queue
processor for the work, to avoid materially impacting the latency of
marking messages as read.

Fixes #7459, though we'll need to open a follow-up issue for
using these data on iOS.

Steve Howell 2e42bdd7c3 Remove "/stats" command for now.
The "/stats" command doesn't actually do anything
interesting yet, and it also writes to the message
feed instead of replying directly to the user.

The history of this command was that it was
written during a PyCon sprint.  It was mainly intended
as an example for subsequent slash commands.  The
ones we built after "/stats" have sort of outgrown
"/stats" and don't follow the original structure
for "/stats".  (The "/day", "/ping", and "/settings"
commands were built shortly after.)j

We probably want to ressurect "/stats" fairly soon,
after figuring out some useful stats and refining
the UI.

As you can see from this commit, resurrecting the
code here shouldn't be too difficult, but it
may actually be pretty rare that we just translate
slash commands into fleshed out messages.
