When our handlers specifically reference self.md.zulip_db_data,
we now use an explicit type.
We probably want a more robust solution here, such as a semgrep
rule.
We now serialize still_url as None for non-animated emojis,
instead of omitting the field. The webapp does proper checks
for falsiness here. The mobile app does not yet use the field
(to my knowledge).
We bump the API version here. More discussion here:

Appending to bytes in a loop leads to a quadratic slowdown since

While accepting an invitation from a user, there was no condition in

Fixes#18569.
We don't have to go to the database to get the Recipient
fields for `user_profile.recipient`.
See also 85ed6f332a from a little
over a year ago--it's very similar.
The bug here probably didn't come up too much in
practice, but if we were adding a user to multiple
streams when they already had used all N available
colors, all the new streams would be assigned the same
color, since the size of used_colors would stay at N,
thwarting our little modulo-len hackery.
It's not a terrible bug, since users can obviously
customize their stream colors as they see fit.
Usually when we are adding a user to multiple streams,
the users are fairly new, and thus don't have many
existing streams, so I have never heard this bug
reported in the field.
Anyway, assigning the colors in bulk seems to make more
sense, and I added some tests.
For the situations where all the colors have already
been used, I didn't put a ton of thought into exactly
which repeated colors we want to choose; instead, I
just ensure they're different modulo 24. It's possible
that we should just have more than 24 canned colors, or
we should just assign the same default color every time
and let users change it themselves (once they've gone
beyond the 24, to be clear). Or maybe we can just do
something smarter here. I don't have enough time for a
deep dive on this issue.
Part of our codepath for subscribing users involves
fetching the users' existing subscriptions to make sure
we can do things like properly report to the clients
that the users were already subscribed. This codepath
used to be coupled to code that helped users maintain
unique stream colors.
Suppose you are creating a new stream, and you are
importing users from an older stream with 15k
subscribers, and each of your users is subscribed to
about 20 streams.
The prior code, instead of filtering on recipient_id,
would literally look at every subscription for every
user, which was kind of crazy if you didn't understand
the pick-stream-color complications.
Before this commit, we would fetch 300k rows with 15
columns each (granted, all but one of the columns are
bool/int). That's a total of 4.5 million tiny objects
that we had to glom into Django ORM objects and slice
and dice.
After this commit, we would fetch exactly zero rows
for the are-they-already-subscribed logic.
Yes, ZERO.
If we were to mistakenly try to re-add the same 15k
subscribers to the new stream (under the new code), we
will now fetch 15k Sub rows instead of 300k.
It is worth looking at the prior commit. We go through
great pains to ensure that users get new stream colors
when we invite them to a stream, and we still fetch a
bunch of data for that. Instead of 4.5 million cells,
it's more like 600k cells (2 columns per row), and it's
less than that insofar as some users may only
have 24 distinct colors among their many streams.
It's a lot of work.
This commit sets us up for the next commit, which will
save us a very expensive query.
If you are adding 15k users to a stream, and each user
has about 20 existing streams, then we need to retrieve
300k rows from the database to figure out which stream
colors they already have. We don't need all the extra
fields from Subscription, so now we get just the two
values we need for making a color map.
In the next commit we'll eliminate the other use case
for the big query, and I will explain in greater
depth how splitting out the color-picking code can
be a huge win. It is possible that some product decisions
could make this codepath easier. We could also do some
engineering specific to stream colors, such as caching
which colors users have already used.
This does cost us an extra round trip to the database.
Having the `wildcard_mentions_notify` setting turned on does
not necessarily mean that the user will receive notification
for that message. There is more nuance to this, as explained
in the updated comment.
We recently ran into a payload in production that didn't contain
an event type at all. A payload where we can't figure out the event
type is quite rare. Instead of letting these payloads run amok, we
should raise a more informative exception for such unusual payloads.
If we encounter too many of these, then we can choose to conduct a
deeper investigation on a case-by-case basis.
With some changes by Tim Abbott.
We avoid repeating the same calculations over and
over again for the same stream.
This helps, but the real bottleneck in this function
is that send_event usually takes at least a millisecond,
and that adds up quickly if you're doing something
like subscribing 5k users to a new stream.
GIF files can be `.GIF`, and also we determine the file format by
inspecting the image data, so there's no reason to have this
assertion.
(The code for serving still images does not rely on the file being a
GIF.)
Have kept process_new_human_user out of
the atomic block because it involves many
different operations and also sends events.
Tried enclosing event in on_commit but that
would need many changes in the tests, so have
skipped it for now.
Updates testing helpers in `event_schema.py` for `do_update_message` so
that all stream message fields are present in any edits / updates to
stream messages. Adds verfication tests of events returned from private
message edits and from stream message content-only and topic-only edits.
Updates the `update_message` event type to always include a `stream_id`
field when the message being edited is a stream message. This change
aligns with the current definition of the `\get-events` endpoint
in the OpenAPI documentation.
It is better to press on, than stop halfway through due to a user
whose email no longer works. The exception is already logged, which
is sufficient here, as this is generally run interactively.
We now complain if a test author sends a stream message
that does not result in the sender getting a
UserMessage row for the message.
This is basically 100% equivalent to complaining that
the author failed to subscribe the sender to the stream
as part of the test setup, as far as I can tell, so the
AssertionError instructs the author to subscribe the
sender to the stream.
We exempt bots from this check, although it is
plausible we should only exempt the system bots like
the notification bot.
I considered auto-subscribing the sender to the stream,
but that can be a little more expensive than the
current check, and we generally want test setup to be
explicit.
If there is some legitimate way than a subscribed human
sender can't get a UserMessage, then we probably want
an explicit test for that, or we may want to change the
backend to just write a UserMessage row in that
hypothetical situation.
For most tests, including almost all the ones fixed
here, the author just wants their test setup to
realistically reflect normal operation, and often devs
may not realize that Cordelia is not subscribed to
Denmark or not realize that Hamlet is not subscribed to
Scotland.
Some of us don't remember our Shakespeare from high
school, and our stream subscriptions don't even
necessarily reflect which countries the Bard placed his
characters in.
There may also be some legitimate use case where an
author wants to simulate sending a message to an
unsubscribed stream, but for those edge cases, they can
always set allow_unsubscribed_sender to True.
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.
These are not considered to be "personal"
info, even if you upload them, so we
don't export them.
Generally the only folks who upload
these are admins, who can easily get
them in other ways. In fact, anybody
can get these via the app.
We now ensure that all message ids are sorted BEFORE
we split them into batches.
We now do a few extra "slim" queries to get message
ids up front.
But, now, when we divide them into batches, we no
longer run 2 or 3 different complicated queries in
a loop. We just basically hydrate our message ids,
so `write_message_partials` should be easy to reason
about.
This change also means that for tiny realms with
< 1000 messages you will always have just one
json file, since we aggregate the ids from the
queries before batching.
This accomplishes a few things:
* It extracts `chunkify` rather than having us
clumsily track chunking-related stuff in a
big loop that is doing other stuff.
* It makes it so that all message ids
in message-000001.json < message-000002.json.
* It makes it easier for us to customize
the messages we send to a single user
(coming soon).
BTW we probably have a slicker version of chunkify
somewhere in our codebase, but I couldn't remember
where.
Now all file writes go through our three
helper functions, and we consistently
write a single log message after the file
gets written.
I killed off write_message_exports, since
all but one of its callers can call
write_table_data, which automatically
sorts data. In particular, our Message
and UserMessage data will now be sorted
by ids.
This probably just postpones the list creation until
Django builds the "IN" query, but semantically it's
good to work in sets where we don't have any
meaningful ordering of the list that gets used.
The immediate benefit of this is stronger mypy
checks (avoiding the ugly union caused by message
files).
The subsequent commit will add sorting.
We have test coverage on all these lines insofar
as if you comment out the lines, tests will
explode (i.e. more than superficial line
coverage).
The distinction here wasn't super meaningful
due to the way we order our "elif" statements,
but we want to reserver "normal_parent" for the
majority of use cases, where you simply tell
the Config what the "foreign_key" is.
For realm-wide exports, there is no reason to query
inefficiently against a list of modified users.
We move the Config out of the common child configs.
Even though Django usually treats foo__in
and foo_id__in identically for filters where
foo is a ForeignKey type, we want to insist
on somewhat more consistent syntax, because
we have the odd combo of type and type_id
in Recipient, where type_id is kinda like a
foreign key, but not a ForeignKey.
So we assert for now that all our include_rows
values end in "_id__in".
Zulip shows two guides on How to reply, first one by
the welcome bot and second one is intro_reply hotspot.
To simply and avoid redundancy, intro_reply hotspot is
removed.
Fixes#20482.
In many of our stream notification messages, we make use of the
same silent user mention syntax, the template for which was always
hardcoded. This commit adds a helper function that all relevant
callers can call to get the right syntax when mentioning users.
Thanks to Tim Abbott for this suggestion!
We don't have automated test coverage on this yet,
but below are the results from manual testing.

though they were not created by Cordelia.

There are tactical reasons to remove this assertion.
Basically, the reason it's safe to remove is that it's
been around a long time and we would have seen this
operationally. Also, the check to make sure that the
S3 filename thingy matches the avatar hash is a much
stronger check.
We will soon restore a stronger version of this check
that applies to all of our asset types (emojis/avatars/etc.).
This makes it easier to read the calling code and see
the big picture of how the four asset types are
organized.
I also handle uploads first, to be similar to the local
code.
This code is well tested--you can modify any of the callers
to pass in a wrong value of `object_key` and get a failing
test.
"help" command occurs in the command list in
initial pms or when bot doesn't understand the message. It doesn't
occur when the bot is respoding to the "help" command itself.
This commit adds code to check whether a user is allowed to use
wildcard mention in a large stream or not while editing a message
based on the realm settings.
Previously this was only checked while sending message, thus user
was easily able to use wildcard mention by first sending a normal
message and then using a wildcard mention by editing it.
1. The initial welcome message now contains less detail.
2. The bot now responds to these commands: "apps", "edit profile",
"dark mode", "light mode", "streams", "topics", "message formatting",
"keyboard shortcuts" and "help" - the bot still responds if there are
slight variations in these commands.
3. Tests have been made to check if bot responds to the advertised
commands (with variations) and gives a negative message if it doesn't
understand the message.

django-scim2 doesn't order the rows when fetching them in reponse to a
query using the filter syntax. We ensure that ORDER BY id is always
appended to the SQL queries.
We add the following tables to the user export:
AlertWord
CustomProfileFieldValue
RealmAuditLog
Service
UserActivity
UserActivityInterval
UserCount
UserGroup
UserHotspot
UserPresence
UserTopic
Except for UserCount, we achieve this by sharing
code with the realm export via
add_user_profile_child_configs.
UserCount is handled slightly differently than realm
exports due to which key we trigger off.
It's possible that RealmAuditLog is incomplete for
single users, since we may also want rows where they
are the acting_user. This commit finds rows where
they are the modified_user. For non-admins I believe
it's rarely the case that they are the actor, and
they will tend to be the modified user if the two
fields are different at all. For admins it's
arguable we want to see both changes they enacted
as well as changes that affected them.
Special characters, including `\r`, `\n`, and more esoteric codepoints
like non-characters, can negatively affect rendering and UI behaviour.
Check for, and prevent making new messages with, characters in the
Unicode categories of `Cc` (control characters), `Cs`, (surrogates),
and `Cn` (unassigned, non-characters).

If null is a potential value of data type for a return value or

is updated, then how the `data_type` for parameters and return values
is rendered will need to be reworked.
Fixes#20264.
RabbitMQ clients have a setting called prefetch[1], which controls how
many un-acknowledged events the server forwards to the local queue in
the client. The default is 0; this means that when clients first
connect, the server must send them every message in the queue.
This itself may cause unbounded memory usage in the client, but also
has other detrimental effects. While the client is attempting to
process the head of the queue, it may be unable to read from the TCP
socket at the rate that the server is sending to it -- filling the TCP
buffers, and causing the server's writes to block. If the server
blocks for more than 30 seconds, it times out the send, and closes the
connection with:
```
closing AMQP connection <0.30902.126> (127.0.0.1:53870 -> 127.0.0.1:5672):
{writer,send_failed,{error,timeout}}
```
This is https://github.com/pika/pika/issues/753#issuecomment-318119222.
Set a prefetch limit of 100 messages, or the batch size, to better
handle queues which start with large numbers of outstanding events.
Setting prefetch=1 causes significant performance degradation in the
no-op queue worker, to 30% of the prefetch=0 performance. Setting
prefetch=100 achieves 90% of the prefetch=0 performance, and higher
values offer only minor gains above that. For batch workers, their
performance is not notably degraded by prefetch equal to their batch
size, and they cannot function on smaller prefetches than their batch
size.
We also set a 100-count prefetch on Tornado workers, as they are
potentially susceptible to the same effect.

Race conditions in stream unsubscription may lead to multiple
back-to-back SUBSCRIPTION_DEACTIVATED RealmAuditLog entries for the
same stream. The current logic constructs duplicate UserMessage
entries for such, which then later fail to insert.
Keep a set of message-ids that have been prep'd to be inserted, so
that we don't duplicate them if there is a duplicated
SUBSCRIPTION_DEACTIVATED row. This also renames the `message` local
variable, which otherwise overrode the `message` argument of a
different type.
Previously, our codebase contained links to various versions of the
Django docs, eg https://docs.djangoproject.com/en/1.8/ref/
request-response/#django.http.HttpRequest and https://
docs.djangoproject.com/en/2.2/ref/settings/#std:setting-SERVER_EMAIL
opening a link to a doc with an outdated Django version would show a
warning "This document is for an insecure version of Django that is no
longer supported. Please upgrade to a newer release!".
Most of these links are inside comments.
Following the replacement of these links in our docs, this commit uses
a search with the regex "docs.djangoproject.com/en/([0-9].[0-9]*)/"
and replaces all matches with "docs.djangoproject.com/en/3.2/".
All the new links in this commit have been generated by the above
replace and each link has then been manually checked to ensure that
(1) the page still exists and has not been moved to a new location
(and it has been found that no page has been moved like this), (2)
that the anchor that we're linking to has not been changed (and it has
been found that no anchor has been changed like this).
One comment where we mentioned a Django version in text before linking
to a page for that version has also been changed, the comment
mentioned the specific version when a change happened, and the history
is no longer relevant to us.
For export realm following changes have been made:
- `./manage.py export --upload` would delete `.tar.gz` and unpacked dir
- `./manage.py export` would only delete `unpacked dir`
Besides, we have removed `--delete-after-upload` as we have set it as
the default.

If realm is web_public, spectators can now view avatar of other

Not proxying these requests through camo is a security concern.
Furthermore, on the desktop client, any embed image which is hosted on
a server with an expired or otherwise invalid certificate will trigger
a blocking modal window with no clear source and a confusing error
message; see zulip/zulip-desktop#1119.
Rewrite all `message_embed_image` URLs through camo, if it is enabled.
Supporting URL percent-encoded bytes is possible using `%%20`, but this
is not necessarily very understandable to end-users, even those that
understand percent encoding.
Allow `%20` in linkifier URL format strings, and transform them into
`%%20` in the pattern just before they are applied in markdown
translation. Care must be taken here, such that already-escaped `%`s
are not escaped an extra time.
We do this before rendering, and not before storage, as
a simplification; the JS-side linkifier at present only understands
`%(foo)s` and thus needs no changes, and to avoid an un-escaping pass
before showing in the admin UI.
og:image is supposed to be an absolute URL, but some sites incorrectly
provide a relative URL. In this case, it makes more sense to
interpret it relative to the full page URL after redirects, rather
than relative to just the domain part of the page URL before
redirects.

This makes logging more consistent between FCM and APNs codepaths, and
makes clear which user-ids are for local users, and which are opaque
integers namespaced from some remote zulip server.
Being able to determine how many distinct users are getting push
notifications per remote host is useful, as is the distribution of
device counts. This parallels the log line in
handle_push_notification for push notifications from local realms,
handled via the event queue.
It is confusing to have the plan type constants not be namespaced
by the thing they represent. We already have a namespacing
convention in place for constants, so we should use it for
Realm.plan_type as well.
`rendered_content` in historical messages may be empty; examining the
history of them may thus require diff'ing two empty strings, which
itself produces an empty string.
Use `lxml.html.fragment_fromstring` to be able to successfully parse

Part of #19559.
As detailed in the comments, the default behavior is undesirable for us
because we can't really predict all possibilities of exceptions that may
be raised - and thus putting str(e) in the http response is potentially
insecure as it may leak some unexpected sensitive information that was
in the exception.
As a hypothetical example - KeyError resulting from some buggy
some_dict[secret_string] call would leak information. Though of course
we aim to never write code like that.
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.

From 430c5cb, in `fetch_initial_state_data`,
we only include legacy settings in the top level of
`state` and the newer ones are stored in `state['user_settings']`.
That should've had a corresponding change in apply_event().
Also, fixed a test related to this logic.
For users who are not logged in and for those who don't have
'prefers_web_public_view' set in session, we redirect them
to the default login page where they can choose to login
as spectator or authenticated user.
This commit adds can_create_web_public_streams helper
in models.py which will be used to validate whether
user is allowed to create a web-public stream or not.
This commit also adds the checks for Realm.POLICY_OWNERS_ONLY
in check_has_permission_policies.
This commit adds tests for POLICY_EVERYONE and POLICY_NOBODY
in check_has_permission_policies test. The original code
used these values but these were not covered in test.
When email_address_visibility is changed and either the old value
or the updated value is EMAIL_ADDRESS_VISIBILITY_EVERYONE then
email field of all users is updated and we also send the corresponding
event to clients. But apply_event code did not update the data on
receiving the event, so this commit fixes the code to correctly
handle the event in apply_event.
(We also use this event when just changing a user's email address).
This commit also adds the tests and openapi schema for the event.
Since the calls to the translation function `_()` are made outside
of the `send_message_moved_breadcrumbs` function, these strings are
translated outside of the `with override_language` block, leading to
translated strings even when we don't intend them to be translated.
We now use gettext_lazy with appropriate testing to avoid this.
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.

the name 'null_tab' gets added. Added the display name 'None' for
'null_tab', to keep in line with the existing behaviour.

This makes our onboarding guide for education organizations much

Fixes#19682
Users wanted a feature where they could specify
which users can create public streams and which users can
create private streams.
This splits stream creation code into two parts,
public and private stream creation.
Fixes#17009.
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.
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.
This commit does not remove the 'enable_login_emails' field from
RealmUserDefault table but it is just not used and cannot be
changed from UI or API similar to 'enable_marketing_emails' setting.
This is a somewhat subtle function, that deserves a few comments
explaining subtle details of its logic, and there's no good reason to
have multiple copies of that logic that are slightly inconsistent.
Because the main changes here are just checking for invariant
failures, the behavioral change here should be limited to ensuring
deactivated streams are not considered available even if they were
tagged as web public streams before deactivation.
This fixes a problem where we could not import zerver.lib.streams from
zerver.lib.message, which would otherwise be reasonable, because the
former implicitly imported many modules due to this issue.
This reverts commit cd93d0967f.
This check_or is redundant with check_union; it gives a misleading
error message for the non-matching case; and it has no type safety.

In maybe_send_resolve_topic_notifications, since the calls to the
translation function `_()` are made outside of the `override_language`
block, the strings are not translated correctly.
This commit refactors the function to make sure that the translation
happens in the right block of code.
Fixes#19730.
Apparently, our slack compatible outgoing webhook format didn't
exactly match Slack, especially in the types used for values. Fix
this by using a much more consistent format, where we preserve their
pattern of prefixing IDs with letters.
This fixes a bug where Zulip's team_id could be the empty string,
which tripped up using GitLab's slash commands with Zulip.
Fixes#19588.
This commit removes the existing default_twenty_four_hour_time field in
Realm table which was used to set the twenty_four_hour_time setting of
new user on joining and instead we now use the twenty_four_hour_time
field of RealmUserDefault table for the same.
With some tweaks by tabbott to clarify the documentation.
These values are currently either a string already or a List[int]. We
should do the conversion in
do_update_user_custom_profile_data_if_changed properly: if the value is
already a string, it can be used directly - if it's not, orjson.dumps is
a more future-proof way of converting than str(). Using orjson.dumps
here also allows us to change the converter of the USER type
CustomProfileField to orjson.loads, which is nicer to have than
ast.literal_eval.
While orjson.dumps() and str() give the same output when
given the special case of List[int],
ast.literal_eval was previously used due to orjson.loads not being
a good inverse function to str in general. That gets straightened out
now.
None of the existing custom profile field types have the value as an
integer like declared in many places - nor is it a string like currently
decalred in types.py. The correct type is Union[str, List[int]]. Rather
than tracking this in so many places throughout the codebase, we add a
new ProfileDataElementValue type and insert it where appropriate.
The old assignment is incorrect - field_value.value is a TextField() and
should always be a string. This didn't strictly break anything, because
django converts the value to a string when .save()ing to the db, but
field_value.value persists as a non-string for the rest of this
codepath. After fixing this, the small codeblock in
notify_user_update_custom_profile_data handling conversion of
field_value.value to a string becomes redundant.
We're assured that we're not breaking event format by the test
test_custom_profile_field_data_events in test_events.py.
Send update event to client after a stream is made web public.
This has been documented in the API documentation since feature level
73; previously the value was always false.
We allow clients to make existing streams web public via the API.
This feature is still disabled via settings in production
environments, because we may have additional policy rules or UI
warnings we wish to add to this sort of conversion.
User can now create web public stream via the /subscribe API.
So, when a web public stream present in the API request does not
exist, it will be created now by specifying the is_web_public
parameter. The parameter would have been ignored without this
commit.
The new error message is more clear about why, "User cannot create
stream with this settings." was bad English, and in any case removing
an unnecessary string is always an improvement for translators.
Recently, we discovered that our settings_tab/relative Markdown
directives didn't work when they were in a macro that was included
in another Markdown file. Note that without this commit, the
/help/create-your-organization-profile page is broken. This commit
changes the respective priorities of these two extensions such that
these directives are rendered *after* the macro is included in
another file.
Thanks to Alya Abbott for reporting this bug!
All of our custom Markdown extensions have priorities that govern
the order in which the preprocessors will be run. It is more
convenient to have these all in one file so that you can easily
discern the order at first glance.
Thanks to Alya Abbott for reporting the bug that led to this
refactoring!
This is a follow-up to #19388.
We will in the future allow patch requests to change the visibility
of an existing topic, so `last_updated` is better name for this field.
This commit does not affect the API or events in any way, but only the
database.
This better matches the title of the page and more generally our
conventions around naming /help/ articles. We include a redirect
because this is referenced from Welcome Bot messages, and we
definitely don't want those links to break.
This parallels fe25517295, but for mobile notifications. It also
adds a test, which verifies that such content does not crash either
mobile or email notifications.
fe25517295 adjusted the email_notifications codepath to use
`lxml.html.fragment_fromstring` method when parsing
`rendered_content`, but left the tests using a helper which called
`fromstring`.
Switching the tests to match the code as run reveals a bug -- using
`drop_tree` on all `message_inline_image` classes now _does_ remove
all of a top-level image-URL-only message. Previously, such messages
were "safe" from the block that calls `drop_tree` only by dint of
`drop_tree` being a silent no-op for the root element. When parsed
using `fragment_fromstring`, they are no longer the root, and as such
an empty message results.
Reorder relative_to_full_url to check for only one `message_inline_image`
within the top `<div>`, and only run the `drop_tree` path in the
alternate case. Tests must be adjusted for their output now including
one more layer of `<div>`.
Our convention is to always have authenticate() called with a request
object. We need to be consistent with that in tests too, to avoid test
failures resulting from breaking that assumption.
We modify assert_login_failure to call client.login() in the same way as
the other similar helpers - with a properly initialized HttpRequest
instance.
Now, when we add a custom animated emoji to the realm
we also save a still image of it (1st frame of the gif). So
we can avoid showing an animated emoji every time.
create_confirmation_link has validity time as an optional argument,
because it has reasonable defaults. Thus it's a better API for
do_send_confirmation_email to make this optional as well, allowing
relying on create_confirmation_link's defaults.
This extends the invite api endpoints to handle an extra
argument, expiration duration, which states the number of
days before the invitation link expires.
For prereg users, expiration info is attached to event
object to pass it to invite queue processor in order to
create and send confirmation link.
In case of multiuse invites, confirmation links are
created directly inside do_create_multiuse_invite_link(),
For filtering valid user invites, expiration info stored in
Confirmation object is used, which is accessed by a prereg
user using reverse generic relations.
Fixes#16359.
The API for changing the batching period was added in
5db4fe8652.
This is a follow up to that commit. We also update the timestamps for
existing scheduled email notifications entries so that the effect of
changing the setting is immediate.

This commit moves check_settings_values to user_settings.py
from validator.py such that we can import the functions at
the top without any issue of cyclic imports.
We do not allow mentioning system user groups for now
because this can lead to circumventing the wildcard
mention restrictions. It will be enabled once we add
a setting to control that.
This is implemented by just ignoring it as one of the
mentioned user group even if the message content
inlcudes the mention syntax for it and the message
is sent normally.
We still keep the for_mention parameter for accessing
user group while sending email and push notifications
as mentioning system user groups will be allowed in
future.
This commit also removes the test for email notifications
for system user groups as we are not allowing mentioning
them.
This commit is only for backend change as we already
exclude the system groups from mention typeaheads and
other UI.
The name of the new realm created as a tombstone after renaming
a realm's subdomain is the constant 'placeholder-realm'.
This would confuse the user when shown the deactivation notice
and asking to join the realm at a new subdomain.
This PR replaces it with the original realm name to avoid confusion.
Fixes: #19677
This commit modifies the copy_user_settings code such that instead
of source user profile, we can have two types of sources - a user
profile and RealmUserDefault table of realm and then set the
settings from RealmUserDefault only is there is no user profile
as a source.
We also rename copy_user_settings to copy_default_settings for
clarity.
This commit adds do_set_realm_user_default_setting which
will be used to change the realm-level defaults of settings
for new users.
We also add a new event type "realm_user_settings_defaults"
for these settings and a "realm_user_settings_default" object
in '/register' response containing all the realm-level default
settings.
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.
This commit changes the type of enable_marketing_emails parameter of
create_user to Optional[bool].
The value of this parameter will be None in certain cases when user
registers through SSO and 'TERMS_OF_SERVICE=False' when there will
be no registration form and thus no value of enable_marketing_emails.
We set the enable_marketing_emails setting after copying user
settings to override the value selected in registration form.
This change is also necessary because enable_marketing_emails
field is present in RealmUserDefault to avoid copying code
but we do not use this value actually and instead we want
the setting to be set according to the value in registration
form.
We set this setting only for non-bot users since we generally
do not set any settings for bots.
We extract the checks for default_language, notification_sound,
and email_notifications_batching_period_seconds setting values
in json_change_settings to a new function check_settings_values.
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).
This check was copied from upstream python-markdown's "safe mode"
before they removed that feature. The upstream history is that they
introduced this check in
2db5d1c8e4,
which was not a complete security check, and then added the
immediately following check (with an allowlist of schemes) in
0b4ffbb60e.
Their first, incomplete check provides no security benefit and makes
the code hard to reason about, so we remove it.
The 'update_global_notifications' type event is sent only for
existing settings and will not be sent for new settings, so we
should use notification_settings_legacy dict to check the type
of setting value in check_update_global_notifications instead
of notification_settings_types dict.
We still used notification_setting_types in copy_user_settings
function of create_user.py and in a test in test_event_system.py.
It is not required to do so since we have added all settings in
property_types already and we loop over property_types at both
these places which includes all settings.
This commit adds `demo_organization_scheduled_deletion_date` to
the `realm` section of the `/register` response so that it is
available to clients when enabled.
This is a part of #19523.
