Alex Vandiver df50280c54 string_validation: Loosen to allow some `Cn` unicode characters.
Under the unicodedata distributed with Python 3.6, some Emoji are
classified as `Cn`, and not `So`:

```
$ unicode 1f929 --long
U+1F929 GRINNING FACE WITH STAR EYES
UTF-8: f0 9f a4 a9 UTF-16BE: d83edd29 Decimal: 🤩 Octal: \0374451
🤩
Category: So (Symbol, Other); East Asian width: W (wide)
Unicode block: 1F900..1F9FF; Supplemental Symbols and Pictographs
Bidi: ON (Other Neutrals)

$ python3.6 -c 'import unicodedata; print(unicodedata.category("\U0001f929"))'
Cn

$ python3.7 -c 'import unicodedata; print(unicodedata.category("\U0001f929"))'
So
```

Drop `Cn` from the list of excluded Unicode character classes, and
replace it with an explicit list of the 66 non-characters, which are
invariant.

Mateusz Mandera 444bb6d0e9 do_delete_user: Create RealmAuditLog entries. 2022-01-04 15:42:03 -08:00
Mateusz Mandera 5939329485 do_delete_user: Add migration to fix bugged UserProfiles.
do_delete_users had two bugs:
1. Creating the replacement dummy users
with active=True
2. Creating the replacement dummy users with email domain set to
realm.uri, which may not be a valid email domain.
Prior commits fixed the bugs, and this migration fixes the pre-existing
objects.

odunybrad 90aa45a316 emoji: Add database-level uniqueness constraint for RealmEmoji.
While races here are unlikely, it is most correct to enforce this
invariant at the database layer, and having a database-level
constraint makes the models file a bit more readable.

UPDATE query to no more than BATCH_SIZE Message rows per query.

the value of `enable_spectator_access`.

Sahil Batra 6ac9386a29 models: Add related_name to UserGroup and UserGroupMembership fields.
This commit adds related_name parameter to UserGroup.direct_members
such that we can use direct_groups instead of the default
usergroupmembership_set for getting all the groups of which the
user is direct member.

This commit also sets related_name of UserGroupMembership.user_group
and UserGroupMembership.user_profile to "+" which means that we will
not be having backward relations for these. This change is correct
since we would need to use the recursive queries to get all the
groups of a user and all the members of a group after we add the
subgroups concept in next commit. This leads to us using direct_members
field of UserGroup instead of usergroupmembership_set in mention code,
but this will soon be replaced with the recursive query function to
include subgroup's members as well.

Extracted this commit from #19866.

Alex Vandiver db934be064 CVE-2021-41115: Use re2 for user-supplied linkifier patterns.
Zulip attempts to validate that the regular expressions that admins
enter for linkifiers are well-formatted, and only contain a specific
subset of regex grammar.  The process of checking these
properties (via a regex!) can cause denial-of-service via
backtracking.

Furthermore, this validation itself does not prevent the creation of
linkifiers which themselves cause denial-of-service when they are
executed.  As the validator accepts literally anything inside of a
`(?P<word>...)` block, any quadratic backtracking expression can be
hidden therein.

Switch user-provided linkifier patterns to be matched in the Markdown
processor by the `re2` library, which is guaranteed constant-time.
This somewhat limits the possible features of the regular
expression (notably, look-head and -behind, and back-references);
however, these features had never been advertised as working in the
context of linkifiers.

A migration removes any existing linkifiers which would not function
under re2, after printing them for posterity during the upgrade; they
are unlikely to be common, and are impossible to fix automatically.

The denial-of-service in the linkifier validator was discovered by
@erik-krogh and @yoff, as GHSL-2021-118.

sahil839 909a3cde76 realm: Replace allow_message_deleting with delete_own_message_policy.
This commit replaces 'allow_message_deleting' boolean setting
with an integer setting 'delete_own_message_policy'. We have a
separate dropdown now for deciding which user-roles can delete
messages sent by themselves and the time-limit setting droddown
is different.

This new setting has two options - everyone and admins only. Other
options including moderators will be added further.

We also remove the "Never" option from the original time-limit
dropdown, as admins are always allowed to delete message. This
never option resembled the case of only admins being allowed to
delete but this state is now resembled by setting the dropdown
to "admins only" and we also disable the time-limit dropdown in
this case as admins are allowed to delete irrespective of limit.

Note, this setting is only for deleting messages sent by the
deleting user themselves, and only admins are allowed to delete
messages sent by others as before.

sahil839 b13bfa09c5 message: Make zero invalid value for message_content_delete_limit_seconds.
We make zero invalid value for message_content_delete_limit_seconds and
for handling the case of "Allow to delete message any time", the API-level
value of message_content_delete_limit_seconds is "anytime" and "None"
as the DB-level value. We also use these values for message retention
setting, so it helps maintain consistency.

sahil839 7d64a9053b models: Ensure every realm has a RealmUserDefault object.
Because we create all realms with do_create_user (including in the
test suite), we just need to change that function, add a migration for
existing realms, and ensure the data import code path correctly
creates these objects.

Note that the import code path will create a RealmUserDefault row with
default values if it is not present in the import data, which is
important for importing data from other tools like Slack.

Tim Abbott c5261af2dc migrations: Fix system bot realm not having a name.
This prevented migration 0345
(517c2ed39d / #19696) from applying on
systems that were created after the refactoring that resulted in the
system bot realm potentially having null as its name.

(We've already confirmed that normal realms, created via
`do_create_realm`, shouldn't be able to have this unusual state).

Tim Abbott 517c2ed39d models: Make realm.name no longer nullable.
This was likely initiall created with null=True in
5c5ffd6ea3 just because we didn't have a
plan for backfilling this field, but I verified that Zulip Cloud has
no realms without a name set, and that's the place most likely to have
any form of super-legacy nameless realms.

So we can clean up this aspect of the data model without a special
migration to do something with existing realms with name=None (which I
suspect would have resulted in a 500 anyway).

Alex Vandiver b011869777 migrations: Add a (profile,end) index on useractivityinterval.
The `user_activity_interval` worker calls:

```python3
    last = UserActivityInterval.objects.filter(user_profile=user_profile).order_by("-end")[0]
`````

Which results in a query like:
```sql
SELECT "zerver_useractivityinterval"."id", "zerver_useractivityinterval"."user_profile_id", "zerver_useractivityinterval"."start", "zerver_useractivityinterval"."end" FROM "zerver_useractivityinterval" WHERE "zerver_useractivityinterval"."user_profile_id" = 12345 ORDER BY "zerver_useractivityinterval"."end" DESC LIMIT 1
```

For users which have at least one matching row, this results in a
query plan like:
```
 Limit  (cost=0.56..711.38 rows=1 width=24) (actual time=0.078..0.078 rows=1 loops=1)
   ->  Index Scan Backward using zerver_useractivityinterval_7f021a14 on zerver_useractivityinterval  (cost=0.56..1031399.46 rows=1451 width=24) (actual time=0.077..0.078 rows=1 loops=1)
         Filter: (user_profile_id = 12345)
         Rows Removed by Filter: 98
 Planning Time: 0.059 ms
 Execution Time: 0.088 ms
```

But for users that have just been created, with no matching rows, this
is considerably more expensive:
```
 Limit  (cost=0.56..711.38 rows=1 width=24) (actual time=10798.146..10798.146 rows=0 loops=1)
   ->  Index Scan Backward using zerver_useractivityinterval_7f021a14 on zerver_useractivityinterval  (cost=0.56..1031399.46 rows=1451 width=24) (actual time=10798.145..10798.145 rows=0 loops=1)
         Filter: (user_profile_id = 12345)
         Rows Removed by Filter: (count of every single row in the table, redacted)
 Planning Time: 0.053 ms
 Execution Time: 10798.158 ms
```

Regular vacuuming can force the use of the index on `user_profile_id`
as long as there are few enough users, which is fast -- however, at
some point, the query planner decides that is insufficiently specific,
always chooses the effective-whole-table-scan.

Add an index on `(user_profile_id, end)`, which is expected to be
sufficiently specific that it is used even with large numbers of user
profiles.

Iam-VM 285e10fe2f migrations: Fix possible 0257_fix_has_link_attribute.py failure.
While it should be an invariant that message.rendered_content is never
None for a row saved to the database, it is possible for that
invariant to be violated, likely including due to bugs in previous
versions of data import/export tools.

While it'd be ideal for such messages to be rendered to fix the
invariant, it doesn't make sense for this has_link migration to crash
because of such a corrupted row, so we apply the similar policy we
already have for rendered_content="".

Mateusz Mandera 1a8ad796f8 models: Replace __id syntax with _id where possible.
model__id syntax implies needing a JOIN on the model table to fetch the

Django is actually smart enough to not do those redundant joins, but we
should still avoid this misguided syntax.

The exceptions are ManytoMany fields and queries doing a backward
relationship lookup. If "streams" is a many-to-many relationship, then
streams_id is invalid - streams__id syntax is needed. If "y" is a
foreign fields from X to Y:
class X:
  y = models.ForeignKey(Y)

then object x of class X has the field x.y_id, but y of class Y doesn't
have y.x_id. Thus Y queries need to be done like
Y.objects.filter(x__id__in=some_list)

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.

Aman Agrawal e587c029f6 display_settings: Allow user to set default_view.
TextField is used to allow users to set long stream + topic narrow
names in the urls.

We currently restrict users to only set "all_messages" and
"recent_topics" as narrows.

This commit achieves 3 things:
* Removes recent topics as the default view which loads when
  hash is empty.
* Loads default_view when hash is empty.
* Loads default_view on pressing escape key when it is unhandled by
  other present UI elements.

NOTE: After this commit loading zulip with an empty hash will
automatically set hash to default_view.  Ideally, we'd just display
the default view without a hash, but that involves extra complexity.

One exception is when user is trying to load an overlay directly,
i.e. zulip is loaded with an overlay hash. In this case,
we render recent topics is background irrespective of default_view.

We consider this last detail to be a bug not important enough to block
adding this setting.

https://docs.djangoproject.com/en/3.1/releases/3.1/

-  The internals of the implementation in the postgresql backend have
   changed a bit in

   and thus we need to make an ugly tweak in test_runner.

Anders Kaseorg b7b7475672 python: Use standard secrets module to generate random tokens.
There are three functional side effects:

• Correct an insignificant but mathematically offensive bias toward
repeated characters in generate_api_key introduced in commit
47b4283c4b4c70ecde4d3c8de871c90ee2506d87; its entropy is increased
from 190.52864 bits to 190.53428 bits.

• Use the base32 alphabet in confirmation.models.generate_key; its
entropy is reduced from 124.07820 bits to the documented 120 bits, but
now it uses 1 syscall instead of 24.

• Use the base32 alphabet in get_bigbluebutton_url; its entropy is
reduced from 51.69925 bits to 50 bits, but now it uses 1 syscall
instead of 10.

(The base32 alphabet is A-Z 2-7.  We could probably replace all of
these with plain secrets.token_urlsafe, since I expect most callers
can handle the full urlsafe_b64 alphabet A-Z a-z 0-9 - _ without
problems.)

    - We allow import tools to continue to

      at import time.

    - We change functions like do_create_user,

    - We keep short_name in the /json/bots

Dinesh dc90d54b08 auth: Add Sign in with Apple support.
This implementation overrides some of PSA's internal backend
functions to handle `state` value with redis as the standard
way doesn't work because of apple sending required details
in the form of POST request.

Includes a mixin test class that'll be useful for testing
Native auth flow.

Thanks to Mateusz Mandera for the idea of using redis and
other important work on this.

Documentation rewritten by tabbott.

Anders Kaseorg 4d04fa3118 compose: Rewrite Zoom video call integration to use OAuth.
This reimplements our Zoom video call integration to use an OAuth
application.  In addition to providing a cleaner setup experience,
especially on zulipchat.com where the server administrators can have
done the app registration already, it also fixes the limitation of the
previous integration that it could only have one call active at a time
when set up with typical Zoom API keys.

Fixes #11672.

Anders Kaseorg 840cf4b885 requirements: Drop direct dependency on mock.
mock is just a backport of the standard library’s unittest.mock now.

The SAMLAuthBackendTest change is needed because
MagicMock.call_args.args wasn’t introduced until Python
3.8 (https://bugs.python.org/issue21269).

The PROVISION_VERSION bump is skipped because mock is still an
indirect dev requirement via moto.

For privacy-minded folks who don't want to leak the
information of whether they're online, this adds an
option to disable sending presence updates to other

The new settings lies in the "Other notification

page, under a "Presence" subheading.

Tim Abbott b246723d83 migrations: Add Message indexes on (recipient_id, subject).
Our previous set of indexes for the Message table did not contain
anything to optimize queries for all the messages in a topic in an
organization where the same topic name might appear in 10,000s of
messages in many streams.

We add two indexes here to support common queries
* A `(recipient_id, upper(subject), id)` index to support
  "Fetch all messages from a topic" queries.
* A `(recipient_id, subject, id)` index to support
  "Fetch all messages by topic"

We use the `DESC NULLS last` on both indexes because we almost always
want to query from the "Latest N messages" on a topic, not the
"Earliest N messages".

These indexes dramatically improve the performance of fetching topic
history (which remains not good enough in my opinion; we'll likely
need caching to make it nice), and more importantly make it possible
to check quickly which users have sent messages to a topic for the
"Topics I follow" feature.

Tim Abbott 8e5b0351b3 alert_words: Fix case-sensitivity of alert words.
Previously, alert words were case-insensitive in practice, by which I
mean the Markdown logic had always been case-insensitive; but the data
model was not, so you could create "duplicate" alert words with the
same words in different cases.  We fix this inconsistency by making
the database model case-insensitive.

I'd prefer to be using the Postgres `citext` extension to have
postgres take care of case-insensitive logic for us, but that requires
installing a postgres extension as root on the postgres server, which
is a pain and perhaps not worth the effort to arrange given that we
can achieve our goals with transaction when adding alert words.

We take advantage of the migrate_alert_words migration we're already
doing for all users to effect this transition.

Fixes #12563.

Abhishek-Balaji 052368bd3e alert_words: Move alert_words from UserProfile to separate model.
Previously, alert words were a JSON list of strings stored in a
TextField on user_profile.  That hacky model reflected the fact that
they were an early prototype feature.

This commit migrates from that to a separate table, 'AlertWord'.  The
new AlertWord has user_profile, word, id and realm(denormalization so
we can provide a nice index for fetching all the alert words in a
realm).

This transition requires moving the logic for flushing the Alert Words
caches to their own independent feature.

Note that this commit should not be cherry-picked without the
following commit, which fixes case-sensitivity issues with Alert Words.
