We now consistently set our query limits so that we get at
least `num_after` rows such that id > anchor. (Obviously, the
caveat is that if there aren't enough rows that fulfill the
query, we'll return the full set of rows, but that may be less
than `num_after`.) Likewise for `num_before`.
Before this change, we would sometimes return one too few rows
for narrow queries.
Now, we're still a bit broken, but in a more consistent way. If
we have a query that does not match the anchor row (which could
be true even for a non-narrow query), but which does match lots
of rows after the anchor, we'll return `num_after + 1` rows
on the right hand side, whether or not the query has narrow
parameters.
The off-by-one semantics here have probably been moot all along,
since our windows are approximate to begin with. If we set
num_after to 100, its just a rough performance optimization to
begin with, so it doesn't matter whether we return 99 or 101 rows,
as long as we set the anchor correctly on the subsequent query.
We will make the results more rigorous in a follow up commit.
We start to force downloads for the attachment files. We do this
for all files except images or pdf's. We would like images or pdf's
to open up in browser itself.

This will allow realm admins to remove others from private stream to
which the realm administrator is not subscribed; this is important for
managing those streams, because previously nobody could remove users
from private streams that didn't have any realm administrators
subscribed.
This will allow realm admins to access subscribers of unsubscribed
private stream. This is a preparatory commit for letting realm admins
remove those users.
This will allow realm admins to update the names and descriptions of
private streams even if they are not subscribed, which fixes the buggy
behavior that previously nobody could(!).
This generic function isolates the before/after logic that really
is independent of Message and doesn't need to clutter up
`get_messages_backend`. Also, introducing a new namespace
reduces some shadowing/mutation with variables like `query`.
It's a pure code move, with some very minor renaming (e.g.
inner_msg_id_col -> id_col).
If anchor is 0, there is no sense doing a before_query.
Likewise, if anchor is `LARGER_THAN_MAX_MESSAGE_ID`, there is
no sense doing an after_query.
We introduce variables called `need_before_query` and
`need_after_query` to enforce those conditions.
This also adds some comments explaining the fallthrough case
where neither query makes sense.
If use_first_unread_anchor is set and we don't have any unread
messages, then our anchor is effectively "positive infinity" and
we can streamline queries.
In the past we'd have clauses like `message_id <= 999999999999999`
in the query that were harmless but crufty.
We want to say `if num_after > 0` when we expect num_after to be
a positive integer. We don't want any confusion that we will
execute the blocks for values of -7 or None.
Apparently, we did essentially all the work to support showing full
topic history to newly subscribed users from a data flow perspective,
but didn't actually enable this feature by having the topic history
endpoint grant access to historical topics. This fixes that gap.
I'm not altogether happy with how the code and tests read for this
feature; the code itself has more duplication than I'd like, and the
tests do too, but it works.
"incorrect" here means rejected by a bot's validate_config() method.
A common scenario for this is validating API keys before the bot is
created. If validate_config() fails, the bot will not be created.
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.
This is necessary for mobile apps to do the right thing when only
RemoteUserBackend is enabled, namely, directly redirect to the
third-party SSO auth site as soon as the user enters the server URL
(no need to display a login form, since it'll be useless).
This got broken at some point when we moved around the context
processing logic for integrations/webhooks. Thankfully, the
context value for external_uri_scheme was only used in a couple of
our less popular integration docs. It should render perfectly now.
Previously, we used to raise an exception if the direct dev login code
path was attempted when:
* we were running under production environment.
* dev. login was not enabled.
Now we redirect to an error page and give an explanatory message to the
user.
Fixes#8249.
This uses an actual query to the backend to check if the subdomain is
available, using the same logic we would use to check when the
subdomain is in fact created.
This adds button under "Organization profile" settings, which
deactivates the organization and sends an "event" to all the
active user and log out them.
Fixes: #8212.
This may be helpful for some API clients, since it avoids them needed
to do somewhat messy post-processing on the results (the data was
always available via scanning for the first unread message in the result).
Fixes#6244.
From here on we start to authenticate uploaded file request before
serving this files in production. This involves allowing NGINX to
pass on these file requests to Django for authentication and then
serve these files by making use on internal redirect requests having
x-accel-redirect field. The redirection on requests and loading
of x-accel-redirect param is handled by django-sendfile.
NOTE: This commit starts to authenticate these requests for Zulip
servers running platforms either Ubuntu Xenial (16.04) or above.
Fixes: #320 and #291 partially.
It catches the `UserProfile.DoesNotExist` exception and
hence prevent internal server error.
Also remove option to select empty bot owner.
Fixes: #8334.
When the answer is False, this will allow the mobile app to show a
warning that push notifications will not work and the server admin
should set them up.
Based partly on Kunal's PR #7810. Provides the necessary backend API
for zulip/zulip-mobile#1507.
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 will let us defer configuring outbound email to the end of the
install procedure, so we can greatly simplify it by consolidating
several scripted steps.
The new flow could be simplified further by giving the user the full
form in the first place, rather than first a form for just their
email address and then a form with the other details. We'll leave
that improvement for a separate change.
Now, there's just one spot at the beginning of the function where we
inspect the string key the user gave us; and after that point, we not
only have validated that string but in fact are working from our own
record that it pointed to, not the string itself.
This simplifies the code a bit, e.g. by not repeatedly searching the
database for the key (and hoping everything agrees so that we keep
getting the same row), and it will simplify adding logic to inspect
row attributes like `presume_email_valid`.
There's no use case for presenting a key that's invalid; if we haven't
given the user a valid key, we needn't send them to a URL that
presents an invalid one. And the code is simpler to think about if
the only keys that can exist (after the validation at the top of the
function) are valid ones.
Apart from the case where creation_key is None, but invalid, and
settings.OPEN_REALM_CREATION is True so that we'd previously let the
invalid key slide, this is a pure refactor.
We'll replace this primarily with per-realm quotas (plus the simple
per-file limit of settings.MAX_FILE_UPLOAD_SIZE, 25 MiB by default).
We do want per-user quotas too, but they'll need some more management
apparatus around them so an admin has a practical way to set them
differently for different users. And the error handling in this
existing code is rather confused. Just clear this feature out
entirely for now; then we'll build the per-realm version more cleanly,
and then we can later add back per-realm quotas modelled after that.
The migration to actually remove the field is in a subsequent commit.
Based in part on work by Vishnu Ks (hackerkid).
This is a little cleaner in that the try/except blocks for
SMTPException are a lot narrower; and it'll facilitate an upcoming
change to sometimes skip sending mail.
This is the first step for allowing users
to edit a bot's service entries, name the
outgoing webhook configuration entries. The
chosen data structures allow for a future
with multiple services per bot; right now,
only one service per bot is supported.
This is responsible for:
1.) Handling all the incoming requests at the
messages endpoint which have defer param set. This is similar to
send_message_backend apart from the fact that instead of really
sending a message it schedules one to be sent later on.
2.) Does some preliminary checks such as validating timestamp for
scheduling a message, prevent scheduling a message in past, ensure
correct format of message to be scheduled.
3.) Extracts time of scheduled delivery from message.
4.) Add tests for the newly introduced function.
5.) timezone: Add get_timezone() to obtain tz object from string.
This helps in obtaining a timezone (tz) object from a timezone
specified as a string. This string needs to be a pytz lib defined
timezone string which we use to specify local timezones of the
users.
This adds UI fields in the bot settings for specifying
configuration values like API keys for a bot. The names
and placeholder values for each bot's config fields are
fetched from the bot's <bot>.conf template file in the
zulip_bots package. This also adds giphy and followup
as embedded bots.
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
There might be case that NOTIFICATION_BOT is none, so before sending stream
announce notification, check first if settings.NOTIFICATION_BOT is not none.
This reverts commit 620b2cd6e.
Contributors setting up a new development environment were getting

The issue appears to be that we're using the `typing` module from the
3.5 stdlib, rather than the `typing=3.6.2` in our requirements files,
and that doesn't understand the `Callable[..., HttpResponse]` that
appears in the definition of `FuncKwargPair`.
Revert for now to get provision working again; at least one person
reports that reverting this sufficed. We'll need to do more testing
before putting this change back in.
Eventually this check for the realm will be done in get_object_from_key
itself. Rewriting this to fit the pattern in get_object_from_key.
No change to behavior.
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]
For example, this means that if a user already has an account on one
realm and they try to make an account on another by hitting "Sign in
with Google" (rather than following the little "Register" link to a
"Sign up with Google" button instead), they'll get to make an account
instead of getting an error.
Until very recently, if the user existed on another realm, any attempt
to register with that email address had to fail in the end, so this
logic gave the user a useful error message early. We introduced it in
c23aaa178 "GitHub: Show error on login page for wrong subdomain"
back in 2016-10 for that purpose. No longer! We now support reusing
an email on multiple realms, so we let the user proceed instead.
This function's interface is kind of confusing, but I believe when its
callers use it properly, `invalid_subdomain` should only ever be true
when `user_profile` is None -- in which case the revised
`invalid_subdomain` condition in this commit can never actually fire,
and the `invalid_subdomain` parameter no longer has any effect. (At
least some unit tests call this function improperly in that respect.)
I've kept this commit to a minimal change, but it would be a good
followup to go through the call sites, verify that, eliminate the use
of `invalid_subdomain`, then remove it from the function entirely.
[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.]
As we migrate to allow reuse of the same email with multiple realms,
we need to replace the old "no email reuse" validators. Because
stealing the email for a system bot would be problematic, we still ban
doing so.
This commit only affects the realm creation logic, not registering an
account in an existing realm.
The one thing this bit of logic is used for is to decide whether
there's an existing user which is a mirror dummy that we should
activate. This change causes us to ignore such an existing user if
it's on some other realm, and go straight into `do_create_user`.
This completes the last commit's work to fix CVE-2017-0910, applying
to any invite links already created before the fix was deployed. With
this change, all new-user registrations must match an explicit realm
in the PreregistrationUser row, except when creating a new realm.
[greg: rewrote commit message]
We would allow a user with a valid invitation for one realm to use it
on a different realm instead. On a server with multiple realms, an
authorized user of one realm could use this (by sending invites to
other email addresses they control) to create accounts on other
realms. (CVE-2017-0910)
With this commit, when sending an invitation, we record the inviting
user's realm on the PreregistrationUser row; and when registering a
user, we check that the PregistrationUser realm matches the realm the
user is trying to register on. This resolves CVE-2017-0910 for
newly-sent invitations; the next commit completes the fix.
[greg: rewrote commit message]
Previously, this was a ValidationError, but that doesn't really make
sense, since this condition reflects an actual bug in the code.
Because this happened to be our only test coverage the ValidationError
catch on line 84 of registration.py, we add nocoverage there for now.
An Integration object doesn't need access to the context dict used
to render its doc.md, since the context dict is just passed directly to
render_markdown_path.
Previously, when rendering a single integration, we tacked on the
following information to the context dict that was redundant:
* An OrderedDict containing all of the Integration objects for
all integrations.
* An OrderedDict containing all of the integration categories.
The context dict for rendering a particular integration doc would
contain 4 OrderedDicts, 2 for categories, 2 for Integration objects
because of how many times add_integrations_context had been called.
This was very wasteful, since an Integration object doesn't need
to access any other Integration object (or itself for that matter)
to render its documentation. This commit adds a function that
allows us to only pass in the context values that are necessary.
This often can cause minor caching problems.
Obviously, it'd be better if we had access to the AST and thus could
do this rule for UserProfile objects in general.
Instead of populating the context dict with integration-specific
information in render_markdown_path, we now do that in
zerver.views.integrations.integration_doc instead.
Fixes#7401.
Tweaked by tabbott to use cast to handle the typing issues here.
This endpoint will allow us to add/delete emoji reactions whose emoji
got renamed during various emoji infra changes. This was also a
required change for realm emoji migration.
This commit was tweaked significantly by tabbott for greater clarity
(with no changes to the actual logic).
