We now send peer_remove events to folks who have never subscribed
to the streams (except for private streams and zephyr).
We also use logic that is more similar to how
bulk_add_subscriptions() works.
There are two reasons for this change. First, we want to be
consistent with notify_subscriptions_added(), which doesn't
handle "peer" events. Second, we want to fix this code in a
subsequent commit not to do one user at a time, which is
inefficient.
merge_vars is the user meta data we store in mailchimp. This commit changes
what we store from realm.domain to realm.id, since realm.domain is being
deprecated, and changes the OPTIN_TIME to a nicer format.
This changes `from django.utils.importlib import import_module` to
`from importlib import import_module`, as `django.utils.importlib` will
be removed in django version 1.9.
Adds a new field org_type to Realm. Defaults for restricted_to_domain
and invite_required are now controlled by org_type at time of realm
creation (see zerver.lib.actions.do_create_realm), rather than at the
database level. Note that the backend defaults are all
org_type=corporate, since that matches the current assumptions in the
codebase, whereas the frontend default is org_type=community, since if
a user isn't sure they probably want community.
Since we will likely in the future enable/disable various
administrative features based on whether an organization is corporate
or community, we discuss those issues in the realm creation form.
Before we actually implement any such features, we'll want to make
sure users understand what type of organization they are a member of.
Choice of org_type (via radio button) has been added to the realm
creation flow and the realm creation management command, and the
open-realm option removed.
The database defaults have not been changed, which allows our testing code
to work unchanged.

This pulls message-related code from models.py into a new
module called message.py, and it starts to break some bugdown
dependencies. All the methods here are basically related to
serializing Message objects as dictionaries for caches and
events.
extract_message_dict
stringify_message_dict
message_to_dict
message_to_dict_json
MessageDict.to_dict_uncached
MessageDict.to_dict_uncached_helper
MessageDict.build_dict_from_raw_db_row
MessageDict.build_message_dict
This fix also removes a circular dependency related
to get_avatar_url.
Also, there was kind of a latent bug in Message.need_to_render_content
where it was depending on other calls to Message to import bugdown
and set it globally in the namespace. We really need to just
eliminate the function, since it's so small and used by code that
may be doing very sketchy things, but for now I just fix it. (The
bug would possibly be exposed by moving build_message_dict out to the
library.)
I move these three functions to lib/cache.py:
to_dict_cache_key_id
to_dict_cache_key
flush_message
This will prepare us for a more significant refactoring that
eventually breaks down some circular dependencies with
Message and bugdown.
This adds support for running a Zulip production server with each
realm on its own unique subdomain, e.g. https://realm_name.example.com.
This patch includes a ton of important features:
* Configuring the Zulip sesion middleware to issue cookier correctly
for the subdomains case.
* Throwing an error if the user tries to visit an invalid subdomain.
* Runs a portion of the Casper tests with REALMS_HAVE_SUBDOMAINS
enabled to test the subdomain signup process.
* Updating our integrations documentation to refer to the current subdomain.
* Enforces that users can only login to the subdomain of their realm
(but does not restrict the API; that will be tightened in a future commit).
Note that toggling settings.REALMS_HAVE_SUBDOMAINS on a live server is
not supported without manual intervention (the main problem will be
adding "subdomain" values for all the existing realms).
[substantially modified by tabbott as part of merging]
We can now rely on UserProfile.last_reminder being time zone
aware, or even if it isn't, it's a self-correcting problem the
first time a reminder is sent. (It's a non-problem to be off
by a few timezones if somebody still has an old value there, because
they will still be outside the 1-minute nag window even with the
timezone disparity.)
We no longer use all the alert words for all the users in the
entire realm when we look for alert words in a newly sent/edited
message. Now we limit the search to only all the alert words
for all the users who will get UserMessage records. This will
hopefully make a big difference for big realms where most messages
are only sent to a small subset of users.
The bugdown parser no longer has a concept of which users need which
alert words, since it can't really do anything actionable with that info
from a rendering standpoint.
Instead, our calling code passes in a set of search words to the parser.
The parser returns the list of words it finds in the message.
Then the model method builds up the list of user ids that should be
flagged as having alert words in the message.
This refactoring is a little more involved than I'd like, but there are
still some circular dependency issues with rendering code, so I need to
pass in the rather complicated realm_alert_words data structure all the way
from the action through the model to the renderer.
This change shouldn't change the overall behavior of the system, except
that it does remove some duplicate regex checks that were occurring when
multiple users may have had the same alert word.
We now use render_incoming_message() to render all incoming
new messages (sends/edits), so that they will get the same treatment.
This change also establishes do_send_messages() as the code
path to get new messages rendered. It removes some
logic from check_message() that only happened on certain code paths
for sending messages, and which would only detect failures by
expensively rendering messages, so it wasn't much of a guard.
This change also helps to phase out maybe_render_content(), which
deepens the call stack without providing much clarity to the reader,
since it's behavior is so variable.
Finally, this sets up to fix a flaw in the way we compute which
users have alert words in their messages (in a subsequent commit).
We now raise an exception in bugdown.do_convert() if rendering
fails, to avoid silent failures, and then calling code can convert
the exception to a JsonableError.
This sends an event when a new avatar is uploaded that refreshes the
avatar for all browser clients without the need to reload the browser.
Fixes: #1359.
Most directly useful for the migration to zulipchat.com.
Creates a new field in UserProfile to store the tos_version, as well as two
new settings TOS_VERSION and FIRST_TIME_TOS_TEMPLATE. We check for a version
mismatch between what the user has signed and the current
settings.TOS_VERSION whenever the user hits the home page, and redirect them
if needed.

zerver.views.accounts_accept_terms were unused before this commit

Adds a new field default language in the zerver_realm model.
This realm level default language will be used as default language

Fixes#1372.
This function is only called in cases where user_profile isn't None,
and the code reads better if we just check that first rather than
checking it on every line that accesses user_profile.
This allows the frontend to fetch data on the subscribers list (etc.)
for streams where the user has never been subscribed, making it
possible to implement UI showing details like subscribe counts on the
subscriptions page.
This is likely a performance regression for very large teams with
large numbers of streams; we'll want to do some testing to determine
the impact (and thus whether we should make this feature only fully
enabled for larger realms).
There were a bunch of authorization and well-formedness checks in
zerver.lib.actions.do_update_message that I moved to
zerver.views.messages.update_message_backend.
Reason: by convention, functions in actions.py complete their actions;
error checking should be done outside the file when possible.
Fixes: #1150.
This is controlled through the admin tab and a new field in the Realms table.
Notes:
* The admin tab setting takes a value in minutes, whereas the backend stores it
in seconds.
* This setting is unused when allow_message_editing is false.
* There is some generosity in how the limit is enforced. For instance, if the
user sees the hovering edit button, we ensure they have at least 5 seconds to
click it, and if the user gets to the message edit form, we ensure they have
at least 10 seconds to make the edit, by relaxing the limit.
* This commit also includes a countdown timer in the message edit form.
Resolves#903.
This is controlled through the admin tab and a new field in the Realms
table. This mirrors the behavior of the old hardcoded setting
feature_flags.disable_message_editing. Partially resolves#903.
Originally this cache was used to transmit data from Django to Tornado
(and also for general message caching purposes), but now nothing
actually reads from this cache, so we can eliminate it.
The functions truncate_content, truncate_body and truncate_topic
are only meant to be used on text strings. So change its
parameter types from AnyStr to text_type.
Change choices of UserProfile.avatar_sources and UserProfile.tutorial_status
from str literals to unicode literals. This is done because these fields
are CharFields, which are of type `six.text_type`. So the set of values
which they can take should also be of the type `six.text_type`.
Also fix clashing annotations.
str_utils.py has functions for converting strings from one type to
another. It also has a TypeVar called NonBinaryStr, which is like AnyStr
except that it doesn't allow bytes.
[Substantially revised by tabbott]
This probably still has some bugs in it, but having mostly complete
annotations for models.py will help a lot for the annotations folks
are adding to other files.
In function bulk_add_subscriptions, some variables were named
`stream_name` but their type is Stream, not a string. Rename
those variables to `stream`.
Long ago, there was work on an experimental integration model where
every user in a realm would have administrative control over all bots,
with the goal of simplifying the process of setting up communally
administered bots for smaller teams. While that new model was never
fully implemented (and thus never setup as an option), an error in
that original implementation meant that the data on all bots in a
realm, including their API keys, was sent to the browsers of users via
the `realm_bots` variable in `page_params`. The data wasn't displayed
in the UI for non-admin users, but was available via e.g. the
javascript console.
This commit updates this behavior to only send sensitive bot data like
API keys to the owner of the bot (and realm admins).
We may in the future implement a model simplifying communally
administered integrations, but if we do that, those bots should be
limited in their capabilities (e.g. only able to send webhook
messages).
This bug has been present since Zulip was released as open source.
The old code for this lookup was unnecessarily complicated because we
were working around Guardian, where the `is_realm_admin` check was
extremely expensive.
This commit adds the capability to keep track and remove uploaded
files. Unclaimed attachments are files that have been uploaded to the
server but are not referred in any messages. A management command to
remove old unclaimed files after a week is also included.
Tests for getting the file referred in messages are also included.
Previously we needed to use a specified password when activating a
formerly mirror dummy user, in order for that user to be able to
(re)set their password and login. Now that we have our own password
reset form, this is no longer required.
As documented in https://github.com/zulip/zulip/issues/441, Guardian
has quite poor performance, and in fact almost 50% of the time spent
running the Zulip backend test suite on my laptop was inside Guardian.
As part of this migration, we also clean up the old API_SUPER_USERS
variable used to mark EMAIL_GATEWAY_BOT as an API super user; now that
permission is managed entirely via the database.
When rebasing past this commit, developers will need to do a
`manage.py migrate` in order to apply the migration changes before the
server will run again.
We can't yet remove Guardian from INSTALLED_APPS, requirements.txt,
etc. in this release, because otherwise the reverse migration won't
work.
Fixes#441.
Replaced calls to ifilterfalse by list comprehensions because
ifilterfalse is not part of python 3. Also changed some lists to sets
for faster lookup.
Refer to #256.
Add a function email_allowed_for_realm that checks whether a user with
given email is allowed to join a given realm (either because the email
has the right domain, or because the realm is open), and use it
whenever deciding whether to allow adding a user to a realm.
This commit is not intended to change any behavior, except in one case
where the Zulip realm's domain was not being converted to lowercase.
While I believe this actually produced correct output since users are
always subscribed to streams within their realm, this code was
definitely wrong.
Discovered using the mypy type-checking tool.
Previously:
* It wouldn't raise an exception if the stream didn't exist
* It didn't correctly handle being passed a stream name
that differed in case from the stream name in the database.
Just doing the database query is more readable, and has about the same
performance as before in the case where active user dicts for the
realm are in cache (and is substantially better in the rare case that
this isn't in the cache).
Thanks to @dbiollo for the perf investigation and suggestion!
get_realm is better in two key ways:
* It uses memcached to fetch the data from the cache and thus is faster.
* It does a case-insensitive query and thus is more safe.
Previously we only did this when new human users were created via the
login process, which meant the management command to create a user did
not add the user to default streams (for example) and any future code
that might want to register a new Zulip user (such as the LDAP
integration) would need to import views/__init__.py in order to
properly set this up.
The do_send_missedmessage_events_reply_in_zulip function in the email
mirror didn't support EMAIL_GATEWAY_PATTERN that wasn't of the form
%s@example.com (which resulted in replies to missed message emails failing
to be parsed).
django commit 596564e80808 stores the user id in the session as a

A stream is vacant when it has no subscribers and occupied when it has at least
one subscriber.
We have a slightly odd model where stream creation is conflated with
subscription creation. Streams are created by attempting to subscribe to a
stream that doesn't exist. We also hide streams with no subscribers from users
to make it seem like they've gone away. However, we can't actually remove those
streams because we want to preserve history.
This commit moves us towards a separation of these two concepts. By sending
events for stream creation, occupation, vacancy, and deletion, we allow clients
to directly observe the global state of streams rather than indirectly observing
subscription information. A more complete solution would involve adding a view
for explicitly creating streams without subscribing to them.
This commit does not handle the intricacies of invite-only streams. We
currently simply do not send these events for invite-only streams.

To mutate the state for removing subscribers, the previous
code was essentially adding in event['subscriptions'] to
state['unsubscribed'], but that was a naive approach, since
the event object only has the name of the subscriber, and not
the full subscription info.
We instead effectively copy records over from state['subscriptions']
to state['unsubscribed'], and we also do surgery on the subscribers
that made me need to add the user_profile parameter to apply_events().
With the code apparently working now, I was able to remove the
match_except() test helper and use a more thorough matcher in
the test on do_remove_subscription().
Part of fixing the "remove" case was cleaning up the "add" case,
since they aren't quite symmetric opposites of each other, although
under this refactoring they now share the new name() helper.

Because full_name and is_admin changes go through many similar,
generic codepaths, it is almost more work at this point to keep
is_admin out of page_params as it is to just put it in. So
I put it in. This should pave the path for showing admins in
the GUI.
This commit actually starting by my adding a test
that calling apply_events() with the notification you get
when calling do_change_is_admin() updates
state['realm_users'] to be similar to what you would get
out of fetch_initial_state_data(). We didn't have test coverage
there before. Making that test pass forced my hand to
either add is_admin to page_params or to special-case
apply_events() not to update page_params with is_admin. I
chose the former approach.

If a name change event arrived during the call to

update the data structure that eventually becomes page_params.
Our update code, instead of surgically updating the fields, was
just overwriting the record, which led to is_bot being taken
out of the record when only full_name was in the event.
Apart from fixing the "update" case to do the right thing,
this commit also does a bit of cleanup on the code handling
"realm_user" events to make it more generic in how it does
add/remove/update. If we could standardize our events a bit
more, this could eventually lead to DRYing up some of the
apply_events() code.

field of UserMessage.

The gather_subscriptions_helper() does a separate query to
get emails from user_ids, and it returns an email_dict to its
caller.
This may seem like a step backward, since gather_subscriptions()
now needs to do an additional query, but there is some benefit
in passing fewer redundant emails over the wire from the DB.
The real payoff, though, will come in subsequent commits, where
we will reduce the amount of data going over the wire to the browser,
which will benefit users with slow connections.

The current version should only be used for testing; for example,
if you want to create a bunch of streams for stress testing, you
can run this in a loop.

It makes the event queue return all messages on public streams, rather

Leo Franchi: Sounds reasonable, but I know way less than zev about DBs so I'll defer to his judgement :)
Steve Howell: Case 2, how the code works now:

Steve Howell: In both trials, we set it up so that only 382 of 9382 rows need to be updated. The first trial runs about 63x as fast. The second trial, if my theory is correct, is doing 24x as many writes as it needs. Both trials are reading all 9382 rows.
Steve Howell: The expense of the update statement seems to be proportional to the number of rows you "update", not the number of rows that you actually change.
Steve Howell: For now I created #1869.
Zev Benjamin: That sounds like a reasonable explanation. The disk IO can be expensive

We now bulk-fetch subscription information once from the database
and use it throughout bulk_add_subscriptions in order to avoid
hitting the db O(streams) times.
On my machine this shaved the accounts_register API call from making
66 queries to making 37 queries.
(imported from commit 5dd5ad3f50b2a6edf85b5f1d55ebd697a1c60647)
When we send a message, we send some presence information to Tornado
to help it figure out how to generate emails for idle recipients of
a message. This change limits the presence info to being the
intersection of present users and recipients of the message. It is
just an internal optimization to avoid queueing up unneeded data.
The history behind this feature is that I implemented it a while
back, but I think I made a rebase mistake that sent all the presence
data over the wire, despite having code to filter on recipients.
It was mostly harmless, just leading to some inefficiency which is
now fixed.

For a 4-person stream, we were hitting the DB 8 times, and 4 of
those queries were to lazily get user.email for the 4 recipients
due to upstream code using only(). I added user_profile__email
to the only() call.
I believe this regression started 9/18, and after pushing this
to prod, we would should look at this graph:

Instead just rely on the 2-minute delay in the management command to

If you expand subscribers on your settings page, you will now see
a query like this in your postgres logs:
SELECT "zerver_userprofile"."email"
FROM "zerver_subscription" INNER JOIN "zerver_recipient" ON ("zerver_subscription"."recipient_id" = "zerver_recipient"."id") INNER JOIN "zerver_userprofile" ON ("zerver_subscription"."user_profile_id" = "zerver_userprofile"."id") WHERE ("zerver_recipient"."type" = 2 AND "zerver_subscription"."active" = true AND "zerver_recipient"."type_id" = 40 AND "zerver_userprofile"."is_active" = true )
The join's still complicated, but the list of fields is one instead of 40+.
(imported from commit 48de1f888193a4d23fcea52d0b633d134e4a3ff7)
get_subscribers_backend() now calls the new get_subscriber_emails()
function, which just queries the email field:
"zerver_userprofile"."email"
...instead of querying about 40 fields that it never uses.
I was able to verify the query slimming by watching my postgres server log.
Also, you can verify that the ORM does roughly 16x less work using values():
>>> def f(): return [sub.user_profile.email for sub in list(Subscription.objects.all().select_related())]
...
>>> def g(): return [row['user_profile__email'] for row in list(Subscription.objects.all().values('user_profile__email'))]
...
>>> def timeit(func): t = time.time(); func(); return time.time() - t
...
>>> timeit(f)
0.045198917388916016
>>> timeit(g)
0.002752065658569336

The get_status_dict_by_realm helper gets called whenever our
realm user_presences cache expires, and it used to query these fields:
"zerver_userpresence"."id", "zerver_userpresence"."user_profile_id", "zerver_userpresence"."client_id", "zerver_userpresence"."timestamp", "zerver_userpresence"."status", "zerver_userprofile"."id", "zerver_userprofile"."password", "zerver_userprofile"."last_login", "zerver_userprofile"."is_superuser", "zerver_userprofile"."email", "zerver_userprofile"."is_staff", "zerver_userprofile"."is_active", "zerver_userprofile"."is_bot", "zerver_userprofile"."date_joined", "zerver_userprofile"."bot_owner_id", "zerver_userprofile"."full_name", "zerver_userprofile"."short_name", "zerver_userprofile"."pointer", "zerver_userprofile"."last_pointer_updater", "zerver_userprofile"."realm_id", "zerver_userprofile"."api_key", "zerver_userprofile"."enable_desktop_notifications", "zerver_userprofile"."enable_sounds", "zerver_userprofile"."enter_sends", "zerver_userprofile"."enable_offline_email_notifications", "zerver_userprofile"."last_reminder", "zerver_userprofile"."rate_limits", "zerver_userprofile"."avatar_source", "zerver_userprofile"."tutorial_status", "zerver_userprofile"."onboarding_steps", "zerver_userprofile"."invites_granted", "zerver_userprofile"."invites_used", "zerver_userprofile"."alert_words", "zerver_userprofile"."muted_topics", "zerver_client"."id", "zerver_client"."name"
Now it queries just the fields it needs:
"zerver_client"."name", "zerver_userpresence"."status", "zerver_userpresence"."timestamp", "zerver_userprofile"."email" FROM "zerver_userpresence"
Also, get_status_dict_by_realm is now namespaced under UserPresence as a static method.

These engagement data will be useful both for making pretty graphs of
how addicted our users are as well as for allowing us to check whether
a new deployment is actually using the product or not.
This measures "number of minutes during which each user had checked
the app within the previous 15 minutes". It should correctly not
count server-initiated reloads.
It's possible that we should use something less aggressive than
mousemove; I'm a little torn on that because you really can check the
app for new messages without doing anything active.
This is somewhat tested but there are a few outstanding issues:
* Mobile apps don't report these data. It should be as easy as having
them send in update_active_status queries with new_user_input=true.
* The semantics of this should be better documented (e.g. the
management script should print out the spec above)x.
