Our recent fixes to using the system's configured memcached settings
broke populate_db, because its hacky clear_database helper is called
with a hacked-up settings module.
We fix this by first moving this out-of-place code from models.py into
populate_db, and then saving the settings required to access memcached
so that we can use them in clear_database.
We also fix a mypy erorr in flush-memcached that matches the same
issue fixed in clear_database.
This experimental setting disables sending private messages in Zulip
in a crude way (i.e. users get an error when they try to send one).
It makes no effort to adjust the UI to avoid advertising the idea of
sending private messages.
Fixes#6617.
Addresses point 1 of #13533.
MissedMessageEmailAddress objects get tied to the specific that was
missed by the user. A useful benefit of that is that email message sent
to that address will handle topic changes - if the message that was
missed gets its topic changed, the email response will get posted under
the new topic, while in the old model it would get posted under the
old topic, which could potentially be confusing.
Migrating redis data to this new model is a bit tricky, so the migration
code has comments explaining some of the compromises made there, and
test_migrations.py tests handling of the various possible cases that
could arise.
Preparatory commit for making the email mirror use the database instead
of redis for missed message addresses.
This model will represent missed message email addresses, which
currently have their data stored in redis.
The redis data will be converted and migrated into these models and
the email mirror will start using them in the main commit.
In 3892a8afd8, we restructured the
system for managing uploaded files to a much cleaner model where we
just do parsing inside bugdown.
That new model had potentially buggy handling of cases around both
relative URLs and URLS starting with `realm.host`.
We address this by further rewriting the handling of attachments to
avoid regular expressions entirely, instead relying on urllib for
parsing, and having bugdown output `path_id` values, so that there's
no need for any conversions between formats outside bugdowm.
The check_attachment_reference_change function for processing message
updates is significantly simplified in the process.
The new check on the hostname has the side effect of requiring us to
fix some previously weird/buggy test data.

For new user onboarding, it's important for it to be easy to verify
that Zulip's mobile push notifications work without jumping through
hoops or potentially making mistakes. For that reason, it makes sense
to toggle the notification defaults for new users to the more
aggressive mode (ignoring whether the user is currently actively
online); they can set the more subtle mode if they find that the
notifications are annoying.
Previously, these accesses used e.g. .select_related("realm"), which
was the only foreign key on the Stream model. Since the intent in
these code paths is to attach the related models for efficient access,
we should just do that for all related models, including Recipient.
With the recipient field being denormalized into the UserProfile and
Streams models, all current uses of get_stream_recipients can be done
more efficiently, by simply checking the .recipient_id attribute on the
appropriate objects.
With the recipient field being denormalized into the UserProfile and
Streams models, all current uses of bulk_get_recipients can be done more
efficient, by simply checking the .recipient_id attribute on the
appropriate objects.
This removes the last of the messy use of regular expressions outside
bugdown to make decisions on whether a message contains an attachment
or not. Centralizing questions about links to be decided entirely
within bugdown (rather than doing ad-hoc secondary parsing elsewhere)
makes the system cleaner and more robust.
Previously, we would naively set has_attachment just by searching
the whole messages for strings like `/user_uploads/...`. We now
prevent running do_claim_attachments for messages that obviously
do not have an attachment in them that we previously ran.
For example: attachments in codeblocks or
attachments that otherwise do not match our link syntax.
The new implementation runs that check on only the urls that
bugdown determines should be rendered. We also refactor some
Attachment tests in test_messages to test this change.
The new method is:
1. Create a list of potential_attachment_urls in Bugdown while rendering.
2. Loop over this list in do_claim_attachments for the actual claiming.
For saving:
3. If we claimed an attachment, set message.has_attachment to True.
For updating:
3. If claimed_attachment != message.has_attachment: update has_attachment.
We do not modify the logic for 'unclaiming' attachments when editing.
This is adds foreign keys to the corresponding Recipient object in the
UserProfile on Stream tables, a denormalization intended to improve
performance as this is a common query.
In the migration for setting the field correctly for existing users,
we do a direct SQL query (because Django 1.11 doesn't provide any good
method for doing it properly in bulk using the ORM.).
A consequence of this change to the model is that a bit of code needs
to be added to the functions responsible for creating new users (to
set the field after the Recipient object gets created). Fortunately,
there's only a few code paths for doing that.
Also an adjustment is needed in the import system - this introduces a
circular relation between Recipient and UserProfile. The field cannot be
set until the Recipient objects have been created, but UserProfiles need
to be created before their corresponding Recipients. We deal with this
by first importing UserProfiles same way as before, but we leave the
personal_recipient field uninitialized. After creating the Recipient
objects, we call a function to set the field for all the imported users
in bulk.
A similar change is made for managing Stream objects.
Fixes#13452.
The migration from UserProfile.is_realm_admin/UserProfile.is_guest in
e10361a832 broke our LDAP-based support
for setting a user's role via LDAP properties, which relied on setting
those fields. Because the django-auth-ldap feature powering that only
supports booleans (and in any case, we don't want to expose constants
like `ROLE_REALM_ADMINISTRATOR` to the LDAP configuration interface),
it makes sense to provide setters for these legacy fields for
backwards-compatibility.
We lint against using these setters directly in Zulip's codebase
directly. The issue with using these is that when changing user's
.role we want to create appropriate RealmAuditLog entries and send
events. This isn't possible when using these setters - the log entries
and events should be created if the role change in the UserProfile is
actually save()-ed to the database - and on the level of the setter
function, it's not known whether the change will indeed be saved.
It would have to be somehow figured out on the level of post_save
signal handlers, but it doesn't seem like a good design to have such
complexity there, for the sake of setters that generally shouldn't be
used anyway - because we prefer the do_change_is_* functions.
The purpose of this change is narrowly to handle use cases like the
setattr on these boolean properties.
If a message begins with /me, we do not have any cases where the
rendered content would not begin with `<p>/me`. Thus, we can safely
remove the redundant checks both on the backend and frontend.
It appears we forgot to make identical changes to the backend
in #11089 while adding support for multiline /me messages,
resulting in any messages that didn't end in a paragraph getting
rendered as a regular message instead.
Fixes#13454.
For a long time, we've been only doing the zxcvbn password strength
checks on the browser, which is helpful, but means users could through
hackery (or a bug in the frontend validation code) manage to set a
too-weak password. We fix this by running our password strength
validation on the backend as well, using python-zxcvbn.
In theory, a bug in python-zxcvbn could result in it producing a
different opinion than the frontend version; if so, it'd be a pretty
bad bug in the library, and hopefully we'd hear about it from users,
report upstream, and get it fixed that way. Alternatively, we can
switch to shelling out to node like we do for KaTeX.
Fixes#6880.
This change makes it possible for users to control the notification
settings for wildcard mentions as a separate control from PMs and
direct @-mentions.
As discussed in the comment, ideally these checks should be added
completely automatically, rather than needing to be manually added
every time we add a new setting. But hopefully the example code for
all of the similar enums that this provides will at least provide some
help.
By adding some additional plumbing (through PreregistrationUser) of the
full_name and an additional full_name_validated option, we
pre-populate the Full Name field in the registration form when coming
through a social backend (google/github/saml/etc.) and potentially skip
the registration form (if the user would have nothing to do there other
than clicking the Confirm button) and just create the account and log
the user in.
We currently have code to calculate the value of realm_icon_url,
admin_emails and default_discount in two diffrent places. With
the addition of showing confirmation links it would become three.
The easiest way to deduplicate the code and make the view cleaner
is by doing the calculations in template. Alternatively one can
write a function that takes users, realms and confirmations as
arguments and sets the value of realm_icon_url, admin_emails and
default_discount appropriately in realm object according to the
type of the confirmation. But that seems more messy than passing
the functions directly to template approach.
There are a few outstanding issues that we expect to resolve beforce
including this in a release, but this is good checkpoint to merge.
This PR is a collaboration with Tim Abbott.
Fixes#716.
Priviously, we rendered the topic links using the msg.sender.realm.
This resulted in issues with Zulip's internal bots not having access
to the realm_filters of the destination stream's realm. For example,
sending a message via the email gateway or notification would not
linkify any realm filters that a user would expect them to.
Fixes#1727.
With the server down, apply migrations 0245 and 0246. 0246 will remove
the pub_date column, so it's essential that the previous migrations
ran correctly to copy data before running this.
1. Apply migration 0243 to add date_sent column.
2. Apply migration 0244 to copy pub_date over to date_sent. Can be done
with the server running.
3. With the server down (for consistency between memory and
database state of Django objects), verify consistency with
Message.objects.exclude(date_sent=F("pub_date")).count() == 0
The previous code for ensuring the sort order of emoji choices was
correct relied on an OrderedDict structure, which isn't guaranteed to
be preserved when passed to the frontend via JSON (in fact, it isn't,
since we converted the way page_params is passed to use
sort_keys=True). Switch it to a list of dictionaries to correct this.
Fixes#13220.
When using our EMAIL_ADDRESS_VISIBILITY_ADMINS feature, we were
apparently creating bot users with different email and delivery_email
properties, due to effectively an oversight in how the code was
written (the initial migration handled bots correctly, but not bots
created after the transition).
Following the refactor in the last commit, the fix for this is just
adding the missing conditional, a test, and a database migration to
fix any incorrectly created bots leaked previously.
This is also a useful preparatory refactor for having a user setting
controlling whether one's own email address is publicly available
within the organization.
Fixes#9401.
This adds a FAKE_EMAIL_DOMAIN setting, which should be used if
EXTERNAL_HOST is not a valid domain, and something else is needed to
form bot and dummy user emails (if email visibility is turned off).
It defaults to EXTERNAL_HOST.
get_fake_email_domain() should be used to get this value. It validates
that it's correctly set - that it can be used to form valid emails.
If it's not set correctly, an exception is raised. This is the right
approach, because it's undesirable to have the server seemingly
peacefully operating with that setting misconfigured, as that could
mask some hidden sneaky bugs due to UserProfiles with invalid emails,
which would blow up the moment some code that does validate the emails
is called.
This requires part 1 (which can take hours to run but generally
doesn't require downtime) to be completed first.
This portion of the migration will require the server to be completely
down for a brief period; for chat.zulip.org with 250M UserMessage
rows, it took about 60s to run; that time will vary depending on
hardware details like whether the server has an SSD, but fundamentally
shouldn't be long.
Our upgrade-zulip and upgrade-zulip-from-git tools can apply this
migration correctly; nothing special needs to be done.
Fixes#13040.
As part of adding support for more than 2B UserMessage rows in a Zulip
server, we need to change UserMessage.id (a field we don't access but
is needed by Django) from an int to a bigint. This commit is a series
of migrations which create a `bigint_id` column and populates it correctly.
This migration will take a long time to run; on chat.zulip.org (a
server with a lot of history), it took about 4 hours to complete.
How to migrate with minimal downtime:
1. Run `upgrade-zulip-from-git` through this commit. It will install
migration 0238 and then more or less hang while applying migration
0239. Once migration 0238 is completed, however, your server should
be able to be started back up safely while migration 0239 is running.
2. Run `/home/zulip/deployments/next/scripts/restart-server` in a
separate terminal to get Zulip running again.
3. When the `upgrade-zulip-from-git` command finishes, it will
automatically re-restart the Zulip server, leaving you in a consistent
state and ready to do part 2 of the migration.
A useful `manage.py shell` query for checking the state after this
commit is consistent is this:
assert UserMessage.objects.exclude(bigint_id=F("id")).count() == 0
Part of #13040.
Instead of having the rather unclear type Union[str,
List[UserDisplayRecipient]] where display_recipient of message dicts was
involved, we use DisplayRecipientT (renamed from DisplayRecipientCacheT
- since there wasn't much reason to have the word Cache in there), which
makes it clearer what is the actual nature of the objects and gets rid
of this pretty big type declaration.
Since the display_recipients dictionaries corresponding to users are
always dictionaries with keys email, full_name, short_name, id,
is_mirror_dummy - instead of using the overly general Dict[str, Any]
type, we can define a UserDisplayRecipient type,
using an appropriate TypedDict.
The type definitions are moved from display_recipient.py to types.py, so
that they can be imported in models.py.
Appropriate type adjustments are made in various places in the code
where we operate on display_recipients.
