This was causing a rather confusing test flake in
test_stream_error_pm_to_bot_owner. What was happening was that if
this test (which used that code path) ran within 5 minutes of the
populate_db run, it would fail.
This commit migrates realm emoji to be addressed by their `id` rather
than their name. This fixes a long standing issue which was causing
an error on uploading an emoji with same name as a deactivated realm
emoji.
Fixes: #6977.
The original implementation of this migration had a highly unfortunate
bug that would result in it deleting all reactions to realm emoji on
the server; we missed this in review, so essentially all historical
realm emoji reactions on chat.zulip.org were lost :(.
We both correct the problem, and also add logging of the deleted rows
that would help should anything be deleted erroneously.
This makes this value much easier for a server admin to change than it
was when embedded directly in the code. (Note this entire mechanism
already only applies on a server open for anyone to create a realm.)
Doing this also means getting the default out of the database.
Instead, we make the column nullable, and when it's NULL in the
database, treat that as whatever the current default is. This better
matches anyway the likely model where there are a few realms with
specially-set values, and everything else should be treated uniformly.
The migration contains a `RenameField` step, which sounds scary
operationally -- but it really does mean just the *field*, in
the model within the Python code. The underlying column's name
doesn't change.
If an emoji that was deleted was the only realm emoji, or more
generally if all realm emoji were deleted, then we would just leave
the reaction unchanged, with an `emoji_code` that is now corrupt.
Instead, treat this case the same as if only this emoji was deleted
while others remain.
Till now, we had been storing realm emoji's name in emoji code field
in reactions' model. This commit migrates it to store realm emoji's id.
It is a part of effort to migrate realm emojis to be referenced by their
id and not by name.
Add `translate_emoticons` to `prop_types` and `expected_keys`.
Furthermore, create a emoji-translating Markdown inline pattern.
Also use a JavaScript version of `translate_emoticons` and then use
this function during Markdown previews and as a preprocessor. This
is only needed for previews, because usually emoticon translation
happens on the backend after sending.
Add tests for emoticon translation, a settings UI, and a /help/ page
as well.
Tweaked by tabbott to fix various test failurse as well as how this
handles whitespace, requiring emoticons to not have adjacent
characters.
Fixes#1768.
Creating the very first organization administrator user and
subscribing them to streams before any messages were sent resulted in
RealmAuditLog entries being created with a `event_last_message_id` of
None, because that's the maximum ID in the empty set.
We correct this by fixing the incorrectly created RealmAuditLog
entries, both for new servers and also fixing old broken entries on
existing servers.
This fixes an issue where if a user setup a Zulip server with just the
organization administrator, and then forgot about it (so that the
initial user became soft-deactivated), trying to sign in 3 weeks later
would throw an exception.
This fixes the issue reported here:
https://chat.zulip.org/#narrow/stream/9-issues/subject/500.20error.20on.20login/near/511981
Users having only account in one realm will not be distracted by realm
name in subject lines of every email. Users who have multiple
accounts in realms can turn this setting on and receive a
corresponding realm name in email's subject.
Tweaked by tabbott to rebase and address a few small issues.
Fixes#5489.
This is easy to do, and prevents this feature from getting a server
admin stuck in potentially a pretty uncomfortable way -- unable to
roll back a deploy.
This reverts commit acebd3a5e, as well as a subsequent fixup commit
0975bebac "quick fix: Fix migrations to be linear."
These changes need more work and thought before they're ready to
deploy on any large established Zulip server, such as zulipchat.com.
See discussion on #6534.
In place of the removed migration, leave behind a placeholder so
`manage.py migrate` doesn't get confused on installs where it was
already applied.
This commit adds a setting to limit creation of generic bots
to admins for realms that want that restriction. (Generic
bots, apart from being considered spammy on some realms,
have less locked down permissions than webhook bots).
Fixes#7066.
We no longer have a special UI setting and model
field ("emoji_alt_code") for saying users want text-only
emojis. We now instead make "text" be a fifth choice
for "emojiset".
Fixes#7406
Commit d4ee3023 and its parent have the history behind this code.
Since d4ee3023^, all new PreregistrationUser objects, except those for
realm creation, have a non-None `realm`. Since d4ee3023, any legacy
PreregistrationUsers, with a `realm` of None despite not being for
realm creation, are treated as expired. Now, we ignore them
completely, and remove any that exist from the database.
The user-visible effect is to change the error message for
registration (or invitation) links created before d4ee3023^ to be
"link does not exist", rather than "link expired".
This change will at most affect users upgrading straight from 1.7 or
earlier to 1.8 (rather than from 1.7.1), but I think that's not much
of a concern (such installations are probably long-running
installations, without many live registration or invitation links).
[greg: tweaked commit message]
[Modified by greg to (1) keep `USERNAME_FIELD = 'email'`,
(2) silence the corresponding system check, and (3) ban
reusing a system bot's email address, just like we do in
realm creation.]
Storage limititations are only set on the value of
a config entry, since this is the only user-accessible
part of the schema. Keys are statically set by each
embedded bot.
This restyles and rewords some of the emoji style section to look
better and fit it more with the current style guide.
Tweaked by tabbott to modify the historical migration rather than
adding a new one. This is OK because the emojiset choices text change
doesn't touch the database; it's just a Django Python code thing.
Also removed translation tags, since we don't need them for a set of
brand names.
This adds the data model and bugdown support for the new UserGroup
mention feature.
Before it'll be fully operational, we'll still need:
* A backend API for making these.
* A UI for interacting with that API.
* Typeahead on the frontend.
* CSS to make them look pretty and see who's in them.
Tweaked by tabbott to have the field before the invitation is
completed be called invite_as_admins, not invited_as_admins, for
readability.
Fixes#6834.
Add this field to the Stream model will prevent us from having
to look at realm data for several types of stream operations, which
can be prone to either doing extra database lookups or making
our cached data bloated.
Going forward, we'll set stream.is_zephyr to True whenever the
realm's string id is "zephyr".
We need a migration to clear the tutorial_status for existing users,
so that we don't show hotspots to anyone who signed up for Zulip in
the month or so since we deleted the old tutorial.
We should have done this a long time ago, but better late than never.
Basically, this migration would crash in the event that there were any
attachments with particularly long names. The fix is the next
migration, 0042; we just inline it here to avoid that crash.
This commit completely switches us over to using a
dedicated model called MutedTopic to track which topics
a user has muted.
This includes the necessary migrations to create the
table and populate it from legacy data in UserProfile.
A subsequent commit will actually remove the old field
in UserProfile.
This is the first part of a larger migration to convert Zulip's
reactions storage to something based on the codepoint, not the emoji
name that the user typed in, so that we don't need to worry about
changes in the names we're using breaking the emoji storage.
This fixes a performance issue that caused this migration to run for a
really long time.
It still takes about 1 minute to run with the 75K Subscription objects
we have on chat.zulip.org, but that's within the realm of acceptable.
ScheduledJob was written for much more generality than it ended up being
used for. Currently it is used by send_future_email, and nothing
else. Tailoring the model to emails in particular will make it easier to do
things like selectively clear emails when people unsubscribe from particular
email types, or seamlessly handle using the same email on multiple realms.
This new setting controls whether or not users are allowed to see the
edit history in a Zulip organization. It controls access through 2
key mechanisms:
* For long-ago edited messages, get_messages removes the edit history
content from messages it sends to clients.
* For newly edited messages, clients are responsible for checking the
setting and not saving the edit history data. Since the webapp was
the only client displaying it before this change, this just required
some changes in message_events.js.
Significantly modified by tabbott to fix some logic bugs and add a
test.
In this commit we are adding two new fields to the UserProfile
table. These fields are the:
long_term_idle: For storing a bool value representing status of user
being online in long time where 'long' will have a specific
definition.
last_active_message_id: For storing the message id which was last
updated into the UserMessage table for a particular user.
This system hasn't been in active use for several years, and had some
problems with it's design. So it makes sense to just remove it to declutter
the codebase.
Fixes#5655.
This will allow for customized senders for emails, e.g. 'Zulip Digest' for
digest emails and 'Zulip Missed Messages' for missed message emails.
Also:
* Converts the sender name to always be "Zulip", if the from_email used to
be settings.NOREPLY_EMAIL_ADDRESS or settings.ZULIP_ADMINISTRATOR.
* Changes the default value of settings.NOREPLY_EMAIL_ADDRESS in the
prod_setting_template to no longer have a display name. The only use of
that display name was in the email pathway.
Once we implement org_type-specific features, it'll be easy to change a
corporate realm to a community realm, but hard to go the other way. The main
difference (the main thing that makes migrating from a community realm to a
corporate realm hard) is that you'd have to make everyone sign another terms
of service.
Instead of deleting the emojis we will just mark them as `deactivated`.
This will prevent their further use but at the same time they will be
displayed properly in the reactions and messages in which they are used.
This field will be used as a flag to indicate whether the realm emoji
has been deleted or not.
Includes a database migration.
This index is basically free, since it only consumes space for
messages that mention the user, but results in a massive performance
improvement when querying messages that mention a user.
This index is essentially free, since it only consumes resources for
starred messages, and massively improves the performance of the
"starred messages" narrow.
Since realm emoji are now required to be lowercase,
an appropriate migration was added to retroactively
fix any emoji that might have contained uppercase
letters.
Also, the validator on the model was changed to
reject uppercase letters.
- Add file_name field to `RealmEmoji` model and migration.
- Add emoji upload supporting to Upload backends.
- Add uploaded file processing to emoji views.
- Use emoji source url as based for display url.
- Change emoji form for image uploading.
- Fix back-end tests.
- Fix front-end tests.
- Add tests for emoji uploading.
Fixes#1134
Useful for the upcoming check_realmauditlog_by_user_query, if nothing else.
But I suspect it will indeed get use; looking for events around or within a
certain time is pretty natural for an audit log.
The main argument against I would say is that this should actually be a
joint index with something else. I'm not sure what that something else
should be, so just optimizing for what I think
check_realmauditlog_by_user_query will need for now.
This commit adds the backend support for a new style of tutorial which
allows for highlighting of multiple areas of the page with hotspots that
disappear when clicked by the user.
This adds an organization description field to the Realm model, as well as
an input field to the organization settings template. Added three tests.
Set the max length of the field to 100 characters.
Fixes#3962.
This makes the outcome if a user didn't have an avatar due to a past
email change reasonable; the user will just be bumped back to
gravatar, fixing their invalid state.
This commit introduces a migration for moving avatars from email based
to user id based storage.
This is in responce to change in behaviour of user_avatar_path to
return path comprising of realm id and a hash based on user id. Also
we fix test_helpers accordingly.
Fixes#3776.
This currently only supports this in emoji reactions, not in actual
emoji in message bodies, but it's a great start for people who want a
text-only view.
Tweaked to update the text by tabbott.
Fixes#3169.
This adds to Zulip support for a user changing their own email
address.
It's backed by a huge amount of work by Steve Howell on making email
changes actually work from a UI perspective.
Fixes#734.
This adds support for only allowing normal users with account age
equal or greater than a "waiting period" threshold to create streams;
this is useful for open organizations that want new members to
understand the community before creating streams.
If create_stream_by_admins_only setting is set to True, only admin users
were able to create streams. Now normal users with account age greater
or equal than waiting period threshold can also create streams.
Account age is defined as number of days passed since the user had
created his account.
Fixes: #2308.
Tweaked by tabbott to clean up the actual can_create_streams logic and
the tests.
This commit adds the following:
1. A reaction model that consists of a user, a message and an emoji that
are unique together (a user cannot react to a particular message more
than once with the same emoji)
2. A reaction event that looks like:
{
'type': 'reaction',
'op': 'add',
'message_id': 3,
'emoji_name': 'doge',
'user': {
'user_id': 1,
'email': 'hamlet@zulip.com',
'full_name': 'King Hamlet'
}
}
3. A new API endpoint, /reactions, that accepts POST requests to add a
reaction to a message
4. A migration to add the new model to the database
5. Tests that check that
(a) Invalid requests cannot be made
(b) The reaction event body contains all the info
(c) The reaction event is sent to the appropriate users
(d) Reacting more than once fails
It is still missing important features like removing emoji and
fetching them alongside messages.
This migration ensures that all historically uploaded files from
before we started tracking files in the Zulip database via the
Attachment model have Attachment objects.
This has been tested by tabbott against a production server to ensure
that it results in all old uploaded files having corresponding
attachment objects.
Merging this change is a key prerequisite for making our adding
attachment access controls in an enforcing fashion.
This makes it possible to configure only certain authentication
methods to be enabled on a per-realm basis.
Note that the authentication_methods_dict function (which checks what
backends are supported on the realm) requires an in function import
due to a circular dependency.
Removes the uniqueness constraint on RealmAlias.domain, and adds a function
can_add_alias that checks for uniqueness conditional on
settings.REALMS_HAVE_SUBDOMAINS.
Previously, we set restrict_to_domain and invite_required differently
depending on whether we were setting up a community or a corporate
realm. Setting restrict_to_domain requires validation on the domain of the
user's email, which is messy in the web realm creation flow, since we
validate the user's email before knowing whether the user intends to set up
a corporate or community realm. The simplest solution is to have the realm
creation flow impose as few restrictions as possible (community defaults),
and then worry about restrict_to_domain etc. after the user is already in.
We set the test suite to explictly use the old defaults, since several of
the tests depend on the old defaults.
This commit adds a database migration.
Adds a database migration, adds a new string_id argument to the management
realm creation command, and adds a short name field to the web realm
creation form when REALMS_HAVE_SUBDOMAINS is False.
Does a database migration to rename Realm.subdomain to
Realm.string_id, and makes Realm.subdomain a property. Eventually,
Realm.string_id will replace Realm.domain as the handle by which we
retrieve Realm objects.
This is a first step towards implementing a message retention policy
feature.
- Add Realm model message_retention_days field to setup
messages expired period for realm.
- Add migration.
- Add tool to get expired messages for each Realm.
- Add tests to cover tool for getting expired messages.
This is a preliminary step towards eliminating the realm.domain field
in favor of realm.subdomain. Includes a database migration to create
these for existing realms.
This adds a medium (500px) size avatar thumbnail, that can be
referenced as `{name}-medium.png`. It is intended to be used on the
user's own settings page, though we may come up with other use cases
for high-resolution avatars in the future.
This will automatically generate and upload the medium avatar images
when a new avatar original is uploaded, and contains a migration
(contributed by Kirill Kanakhin) to ensure all pre-existing avatar
images have a medium avatar.
Note that this implementation does not provide an endpoint for
fetching the medium-size avatar for another user.
[substantially modified by tabbott]
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.
[includes some HTML/CSS work by Brock Whittaker to make it look nice]
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]
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.
Note that accounts_accept_terms.html and
zerver.views.accounts_accept_terms were unused before this commit
(they date from c327446537)
Adds a new field default language in the zerver_realm model.
This realm level default language will be used as default language
for newly created users. Realm level default language can be
changed from the administration page.
Fixes#1372.
The MitUser model caused a constant series of little problems for
users with mit.edu email addresses trying to sign up for different
Zulip servers.
The new implementation just uses conditionals on the realm object when
selecting the confirmation template to use.
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.
Squash the AlterField on UserProfile.groups in 0002 into the
AddField in 0001. This is done to avoid a probable bug in Django,
where running migrations in python 3 sometimes led to a KeyError.
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.
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.
89a2765553 didn't include the database
migration corresponding to the change, which means it didn't take full
effect when it was merged.
I noticed this because `manage.py makemigrations` would generate these
migrations; that suggests a good idea for a test to add.
This fixes a performance issue looking up UserProfile objects for
realms with a large number of users in the case that a UserProfile
object is not in the cache.
Thanks to @dbiollo for the suggestion!

Apply this commit after hours!
To apply this commit, first run the migration and then run the following as the
zulip user on staging:
$ echo 'VACUUM zerver_message' | python manage.py dbshell
The above VACUUM is needed to clean out the existing fast update pending list.
It might take a long time and block new message inserts!
See discussion near Zulip message 18377486 for why we're turning off the fast
update mechanism for zephyr_message_search_tsvector.
The high level overview is:
As a consequence of the high work_mem setting on our postgres server, the
fastupdate pending list for zephyr_message_search_tsvector can grow very large.
This leads to the occasional INSERT or UPDATE taking inordinately long (many
minutes) as the pending list is flushed, blocking other inserts.
One other possible solution for preventing the list from growing too large is to
set the autovacuum storage parameters on the table such that the autovacuum
process will run after a reasonable number of INSERTs or UPDATEs. However, the
table is mostly INSERT-only. Therefore, only the autovacuum_analyze_*
parameters will actually do anything to affect when the autovacuumer will run,
but when it does, it will do a VACUUM ANALYZE instead of a plain VACUUM. We
don't particularly need the table to be re-analyzed that often.
Turning off fast update will eventually cause the index to become less
efficient, but we can always rebuild it later if we notice it starting to get
too slow.

We need to run the schema migration manually using
"CREATE INDEX CONCURRENTLY upper_stream_name_idx ON zerver_stream ((upper(name)));"
since we need CONCURRENTLY and I seem to recall that doesn't work with South.
This significantly improves the uncached performance of get_stream()
(e.g. from 32ms to 9ms). At present, this codepath is not used
particularly heavily since we do cache the stream names and do most of
our filtering by recipient ID, but the index isn't expensive and does
provide a significant improvement in the uncached case.

"CREATE INDEX CONCURRENTLY upper_subject_idx ON zerver_message ((upper(subject)));"
since we need CONCURRENTLY and I seem to recall that doesn't work with South.
Apparently our existing indexes on subject/topic weren't being used in
our narrowing queries, because we do case-insensitive search.
This substantially improves our database performance around
stream+topic narrows. See before and after query plans below from my
test instance.
humbug=# explain analyze SELECT "zerver_message"."id" FROM "zerver_message" WHERE ("zerver_message"."recipient_id" = 38 AND UPPER(zerver_message.subject) = 'TEST' AND "zerver_message"."id" <= 348495 ) ORDER BY "zerver_message"."id" DESC LIMIT 50;

In order to support iOS Push Notifications, we need to keep track
of a device's unique APNS Token. These are delivered to our iOS
code after registering for remote notifications
(imported from commit bbe34483e1380dc20a1c93e3ffa1fcfdb9087e67)
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.

This commit CANNOT be deployed until the previous schema change
([schema] models: add an email_token field to Streams) is on prod.
Before applying this schema change, run the populate-stream-tokens
management command to generate tokens for streams that need them.
(imported from commit 7adc81c8c317ec5d59dd59ba42a4dc1a46174007)
The e-mail forwarder will use this. Set it to nullable temporarily to
accomodate existing streams; later commits will a) provide a script to
give all streams a token, and b) make the field non-null.
Realm administrators will eventually have a UI to regenerate stream
tokens.

This needs to be deployed to both staging and prod at the same
off-peak time (and the schema migration run).
At the time it is deployed, we need to make a few changes directly in
the database:
(1) UPDATE django_content_type set app_label='zerver' where app_label='zephyr';
(2) UPDATE south_migrationhistory set app_name='zerver' where app_name='zephyr';
