The flow in recipient_for_user_profiles previously worked by doing
validation on UserProfile objects (returning a list of IDs), and then
using that data to look up the appropriate Recipient objects.
For the case of sending a private message to another user, the new
UserProfile.recipient column lets us avoid the query to the Recipient
table if we move the step of reducing down to user IDs to only occur
in the Huddle code path.
This is adds foreign keys to the corresponding Recipient object in the
UserProfile on Stream tables, a denormalization intended to improve
performance as this is a common query.
In the migration for setting the field correctly for existing users,
we do a direct SQL query (because Django 1.11 doesn't provide any good
method for doing it properly in bulk using the ORM.).
A consequence of this change to the model is that a bit of code needs
to be added to the functions responsible for creating new users (to
set the field after the Recipient object gets created). Fortunately,
there's only a few code paths for doing that.
Also an adjustment is needed in the import system - this introduces a
circular relation between Recipient and UserProfile. The field cannot be
set until the Recipient objects have been created, but UserProfiles need
to be created before their corresponding Recipients. We deal with this
by first importing UserProfiles same way as before, but we leave the
personal_recipient field uninitialized. After creating the Recipient
objects, we call a function to set the field for all the imported users
in bulk.
A similar change is made for managing Stream objects.
In configurations with LDAP_APPEND_DOMAIN, we don't want people creating
non-ldap accounts with emails matching the ldap domain.
So in the registration flow, if the email isn't found in LDAP, but
matches LDAP_APPEND_DOMAIN, we stop, rather than proceeding with account
creation. In case of emails not matching LDAP_APPEND_DOMAIN, we will
still continue to make a normal, non-ldap account.
For a long time, we've been only doing the zxcvbn password strength
checks on the browser, which is helpful, but means users could through
hackery (or a bug in the frontend validation code) manage to set a
too-weak password. We fix this by running our password strength
validation on the backend as well, using python-zxcvbn.
In theory, a bug in python-zxcvbn could result in it producing a
different opinion than the frontend version; if so, it'd be a pretty
bad bug in the library, and hopefully we'd hear about it from users,
report upstream, and get it fixed that way. Alternatively, we can
switch to shelling out to node like we do for KaTeX.
Fixes#6880.
When creating realm with the ldap backend, the registration flow didn't
properly handle some things - the user wouldn't be set as realm admin,
initial subscriptions and messages weren't created, and the redirect
wasn't happening properly in the case of subdomains.
By adding some additional plumbing (through PreregistrationUser) of the
full_name and an additional full_name_validated option, we
pre-populate the Full Name field in the registration form when coming
through a social backend (google/github/saml/etc.) and potentially skip
the registration form (if the user would have nothing to do there other
than clicking the Confirm button) and just create the account and log
the user in.
This changes the way django_to_ldap_username works to make sure the ldap
username it returns actually has a corresponding ldap entry and raise an
exception if that's not possible. It seems to be a more sound approach
than just having it return its best guess - which was the case so far.
Now there is a guarantee that what it returns is the username of an
actual ldap user.
This allows communicating to the registration flow when the email being
registered doesn't belong to ldap, which then will proceed to register
it via the normal email backend flow - finally fixing the bug where you
couldn't register a non-ldap email even with the email backend enabled.
These changes to the behavior of django_to_ldap_username require small
refactorings in a couple of other functions that call it, as well as
adapting some tests to these changes. Finally, additional tests are
added for the above-mentioned registration flow behavior and some
related corner-cases.
MigrationsTestCase is intentionally omitted from this, since migrations
tests are different in their nature and so whatever setUp()
ZulipTestCase may do in the future, MigrationsTestCase may not
necessarily want to replicate.
Previously, the logic for determining whether to provide an LDAP
password prompt on the registration page was incorrectly including it
if any LDAP authentication was backend enabled, even if LDAP was
configured with the populate-only backend that is not responsible for
authentication (just for filling in name and custom profile fields).
We fix this by correcting the conditional, and add a test.
There's still follow-up work to do here: We may still end up
presenting a registration form in situations where it's useless
because we got all the data from SAML + LDAP. But that's for a future
issue.
This fixes a bug reported in #13275.
Fixes#1727.
With the server down, apply migrations 0245 and 0246. 0246 will remove
the pub_date column, so it's essential that the previous migrations
ran correctly to copy data before running this.
After a new user joins an active organization, it isn't obvious what
to do next; this change causes there to be recent unread messages in
the stream sidebar for the user to click on to get a feel for what's
happening in the organization and experiment with Zulip.
Fixes#6512.
Hopefully this does a better job of spurring people to action, and also
suggests a self-service fix if they don't (i.e. contacting the person that
invited them).
This was used as a helper to construct the final display_recipient when
fetching messages. With the new mechanism of constructing
display_recipient by fetching appropriate users/streams from the
database and cache, this shouldn't be needed anymore.
The user information in display_recipient in cached message_dicts
becomes outdated if the information is changed in any way.
In particular, since we don't have a way to find all the message
objects that might contain PMs after an organization toggles the
setting to hide user email addresses from other users, we had a
situation where client might see inaccurate cached data from before
the transition for a period of up to hours.
We address this by using our generic_bulk_cached_fetch toolchain to
ensure we always are fetching display_recipient data from the database
(and/or a special recipient_id -> display_recipient cache, which we
can flush easily).
Fixes#12818.
Rename notification property `enable_stream_sounds` to
`enable_stream_audible_notifications` to match with other
notification property patterns.
Fixes part of #12304
This cleans up the pattern for how we check which user is logged in
during Zulip's backend unit tests to be much more readable (replacing
the arcane session code that does this check).
This makes the implementation of `get_realm` consistent with its
declared return type of `Realm` rather than `Optional[Realm]`.
Fixes#12263.

The hope is that by having a shorter list of initial streams, it'll
avoid some potential confusion confusion about the value of topics.
At the very least, having 5 streams each with 1 topic was not a good
way to introduce Zulip.
This commit minimizes changes to the message content in
`send_initial_realm_messages` to keep the diff readable. Future commits will
reshape the content.
We never intended to render them for this use case as the result would
not look good, and now we have a convenient bugdown option for
controlling this behavior.
Since we're not storing the markdown rendering anywhere, there's
conveniently no data migration required.
Fixes#11889.
Follow up on 92dc363. This modifies the ScheduledEmail model
and send_future_email to properly support multiple recipients.
Tweaked by tabbott to add some useful explanatory comments and fix
issues with the migration.
Apparently, our invalid realm error page had HTTP status 200, which
could be confusing and in particular broken our mobile app's error
handling for this case.
ACCOUNT_ACTIVATION_DAYS doesn't seems to be used anywhere.
INVITATION_LINK_VALIDITY_DAYS seems to do it's job currently.
(It was only ever used in very early Zulip commits).
For Google auth, the multiuse invite key should be stored in the
csrf_state sent to google along with other values like is_signup,
mobile_flow_otp.
For social auth, the multiuse invite key should be passed as params to
the social-auth backend. The passing of the key is handled by
social_auth pipeline and made available to us when the auth is
completed.
This replaces the current usage of stream names with stream ids.
This commit also removes the `traditional` attribute from the invite
form as now we are sending stream_ids as an argument; this was the
only place in the codebase we used traditional=true, and it's great to
have it removed.
`fakeldap` assumes every attribute to be a multi-value attribute
while making comparison in `_comapare_s()` and so while making
comparisons for password it gives a false positive. The result
of this was that it was possible to login in the dev environment
using LDAP using a substring of the password. For example, if the
LDAP password is `ldapuser1` even entering `u` would log you in.
Previously, zerver.views.registration.confirmation_key was only
available in development; now we make that more structurally clear by
moving it to the special zerver/views/development directory.
Fixes#11256.
Since we have already added the `invite_as` field to models, we can now
replace usage of `invite_as_admin` properly with its equivalent `invite_as
== PreregistrationUser.INVITE_AS['REALM_ADMIN']`.
Hence, also removed now redundant `invite_as`.
Note that a pretty common use case for this is a realm admin sending this to
everyone after an import from HipChat or Slack. So this adds the realm_name
to the title (so that there is something they might recognize) and kept the
wording generic enough to accommodate the user not having clicked anything
to get this email.
Also strengthens the tests a bit to better test the complicated template
logic.
This checks if push_notification_enabled() is set to false in
handle_push_notification and adds an early return statement.
This is a significant performance optimization for our unit tests
because the push notifications code path does a number of database
queries, and this migration means we don't end up doing those queries
the hundreds of times we send PMs or mentions in our tests where we're
not trying to test the push notifications functionality.
This should also have a small message sending scalability improvement
for any Zulip servers without push notifications enabled.
Tweaked by tabbott to fix a few small issues.
Fixes#10895.
Apparently, Django's get_current_site function (used, e.g., in
django-two-factor to look up the domain to use in QR codes) first
tries to use the Sites framework, and if unavailable, does the right
thing (namely, using request.get_host()).
We don't use the Sites framework for anything in Zulip, so the correct
fix is to just remove it.
Fixes#11014.
This styles the avatar and username that show when the registering
user is importing their settings from an existing Zulip account.
Tweaked by tabbott to fix the test/linter failures, a bit of styling,
and tag strings for translation.
This adds a function that sends provided email to all administrators
of a realm, but in a single email. As a result, send_email now takes
arguments to_user_ids and to_emails instead of to_user_id and
to_email.
We adjust other APIs to match, but note that send_future_email does
not yet support the multiple recipients model for good reasons.
Tweaked by tabbott to modify `manage.py deliver_email` to handle
backwards-compatibily for any ScheduledEmail objects already in the
database.
Fixes#10896.
This is largely inspired by requests from people not liking the
Google's new emojiset. A lot of people were requesting to revert
back to old blobs emojiset so we are re-enabling this feature
after making relevant infrastructure changes for supporting google's
old blob emojiset and re-adding support for twitter emojiset.
Fixes: #10158.
Also use name for selecting form in casper tests
as form with action=new is present in both /new
and /accounts/new/send_confirm/ which breaks
test in CircleCI as
waitWhileVisible('form[action^="/new/"]) never stops
waiting.
The function being tested here was kind of an
emergency response to some spam attacks. It
works for a pretty specific set of circumstances,
so it requires a lot of setup.
We may eliminate this function as we improve
our realm "plan types", and if that happens, we
can either eliminate this test or repurpose it.
We have code to prevent newbies on open realms
from inviting users. This is mostly intended
to hinder spammers. This commit just adds some
test coverage.
This uses the recently introduced active_mobile_push_notification
flag; messages that have had a mobile push notification sent will have
a removal push notification sent as soon as they are marked as read.
Note that this feature is behind a setting,
SEND_REMOVE_PUSH_NOTIFICATIONS, since the notification format is not
supported by the mobile apps yet, and we want to give a grace period
before we start sending notifications that appear as (null) to
clients. But the tracking logic to maintain the set of message IDs
with an active push notification runs unconditionally.
This is designed with at-least-once semantics; so mobile clients need
to handle the possibility that they receive duplicat requests to
remove a push notification.
We reuse the existing missedmessage_mobile_notifications queue
processor for the work, to avoid materially impacting the latency of
marking messages as read.
Fixes#7459, though we'll need to open a follow-up issue for
using these data on iOS.
Historically, queue_json_publish had a special third argument that was
basically its default mock behavior in the test suite. We've been
migrating away from that model, because it was confusing and resulted
in poor test coverage of our queue worker code paths; this was one of
the last holdouts.
As it turns out, we don't exercise this code path in a way that
impacts tests much; the main downside of this change is a likely small
penalty to performance of the full test suite when sending private
messages.
Since otp_encrypt_api_key only encrypts API keys, it doesn't require
access to the full UserProfile object to work properly. Now the
parameter it accepts is just the API key.
This is preparatory refactoring for removing the api_key field on
UserProfile.
This renames Realm.restricted_to_domain field to
emails_restricted_to_domains, for greater clarity as to what it does
just from seeing the setting name, without having to look it up.
Fixes part of #10042.
The only changes visible at the AST level, checked using

'\\[[X| ]\\] (\\d+_.+)\n' ↦ '\\[[X| ]\\] (\\d+_.+)\\n'
which is fine because re treats '\\x1b' and '\\n' the same way as
'\x1b' and '\n'.

Previously, if you had LDAPAuthBackend enabled, we basically blocked
any other auth backends from working at all, by requiring the user's
login flow include verifying the user's LDAP password.
We still want to enforce that in the case that the account email
matches LDAP_APPEND_DOMAIN, but there's a reasonable corner case:
Having effectively guest users from outside the LDAP domain.
We don't want to allow creating a Zulip-level password for a user
inside the LDAP domain, so we still verify the LDAP password in that
flow, but if the email is allowed to register (due to invite or
whatever) but is outside the LDAP domain for the organization, we
allow it to create an account and set a password.
For the moment, this solution only covers EmailAuthBackend. It's
likely that just extending the list of other backends we check for in
the new conditional on `email_auth_backend` would be correct, but we
haven't done any testing for those cases, and with auth code paths,
it's better to disallow than allow untested code paths.
Fixes#9422.
This is the analog of the last commit, for the password reset flow.
For these users, they should be managing/changing their password in
the LDAP server.
The error message for users doing the wrong thing here is nonexistent
isn't great, but it should be a rare situation.
This should significantly improve the user experience for creating
additional accounts on zulipchat.com.
Currently, disabled in production pending some work on visual styling.
Since this is a logged-out view, need to actually write code for the
case of deactivated realms.
The change to get_active_user is more for clarity; the Django password
reset form already checks for whether the user is active earlier.
This test class is basically a poor version of the end-to-end tests
that we have in `test_auth_backends.py`, and didn't really add any
value other than making it difficult to refactor.
In this commit we start to support redirects to urls supplied as a
'next' param for the following two backends:
* GoogleOAuth2 based backend.
* GitHubAuthBackend.
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.
This changes the followup_day2 emails delay from one day later to two days
later if it is getting delivered on any working days(i.e. Mon - Fri).
For Thursday it is compromised to next day as it would be too late to
postponed to Monday and for Friday it should be Monday.
At last actually, emails should send one hour before the above calculated so
that user can catch them when they are dealing with these kinds of stuff.
Fixes: #7078.
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 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.
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]
We should omit these for mypy. For most class definitions,
mypy doesn't need `Any`, and it provides no real useful info.
For clever monkeypatches, you should provide a more specific
type than `Any`.
The original logic is buggy now that emails can belong to (and be
invited to) multiple realms.
The new logic in the `invites` queue worker also avoids the bug where
when the PreregistrationUser was gone by the time the queue worker got
to the invite (e.g., because it'd been revoked), we threw an exception.
[greg: fix upgrade-compatibility logic; add test; explain
revoked-invite race above]
This code changes frequently enough that errors are bound to creep in. The
main change is that this sends the original invitation email instead of the
reminder email, but I think that's fine.
We'll need the expanded test coverage when we move
check_prereg_key_and_redirect to zerver/views/registration.py to avoid
test failures, and these are also tests we should really have anyway.
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.
Just now this is largely redundant with `test_signup_already_active`;
but very soon when we allow reusing an email across realms, the logic
will diverge.
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.
The installation admin is not the right person to get support requests from
deactivated users, regardless of the situation.
Also updates the wording to be a bit more concise.
This was basically rewritten by tabbott, because the code is a lot
cleaner after just rewriting the ZulipPasswordResetForm code to no
longer copy the model of the original Django version.
Fixes#4733.
This adds tests for a new more cases. Some were already covered
elsewhere in the codebase, but it feels best for LoginTest to fully
cover OurAuthenticationForm.
We don't have our linter checking test files due to ultra-long strings
that are often present in test output that we verify. But it's worth
at least cleaning out all the ultra-long def lines.
This change:
* Prevents weird potential attacks like taking a valid confirmation link
(say an unsubscribe link), and putting it into the URL of a multiuse
invite link. I don't know of any such attacks one could do right now, but
reasoning about it is complicated.
* Makes the code easier to read, and in the case of confirmation/views.py,
exposes something that needed refactoring anyway (USER_REGISTRATION and
INVITATION should have different endpoints, and both of those endpoints
should be in zerver/views/registration, not this file).
Because this is for tests, a heuristic like this that's right in most
situations is actually fine; we can override it in the few cases where
a test might set up a situation where it fails.
So just make it clear for the next reader that that's what's going on,
and also adjust the helper's interface slightly so that its callers
do have that flexibility.
Do you call get_recipient(Recipient.STREAM, stream_id) or
get_recipient(stream_id, Recipient.STREAM)? I could never
remember, and it was not very type safe, since both parameters
are integers.
The cookie mechanism only works when passing the login token to a
subdomain. URLs work across domains, which is why they're the
standard transport for SSO on the web. Switch to URLs.
Tweaked by tabbott to add a test for an expired token.
Most of these have more to do with authentication in general than with
registering a new account. `create_preregistration_user` could go
either way; we move it to `auth` so we can make the imports go only in
one direction.
Lets administrators view a list of open(unconfirmed) invitations and
resend or revoke a chosen invitation.
There are a few changes that we can expect for the future:
* It is currently possible to invite an email that you have already
invited, it might make sense to change this behavior.
* Resend currently sends an invite reminder instead of resending the
original invite, this is because 'custom_body' was not stored when
the first invite was sent.
Tweaked in various minor ways, primarily in the backend, by tabbott,
mostly for style consistency with the rest of the codebase.
Fixes: #1180.
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.
In do_send_messages, we only produce one dictionary for
the event queues, instead of different flavors for text
vs. html. This prevents two unnecessary queries to the
database.
It also means we only put one dictionary on the "message"
event queue instead of two, albeit a wider one that has
some values that won't be sent to the actual clients.
This wider dictionary from MessageDict.wide_dict is also
used for the `feedback_messages` queue and service bot
queues. Since the extra fields are possibly useful down
the road, and they'll just be ignored for now, we don't
bother to remove them. Also, those queue processors won't
have access to `content_type`, which they shouldn't need.
Fixes#6947
Every time we updated a UserProfile object, we were calling
delete_display_recipient_cache(), which churns the cache and
does an extra database hop to find subscriptions. This was
due to saying `updated_fields` instead of `update_fields`.
This made us prone to cache churn for fields like UserProfile.pointer
that are fairly volatile.
Now we use the helper function changed(). To prevent the
opposite problem, we use all the fields that could invalidate
the cache.
While our recent changing to hide /register means we don't need a nice
pretty error message here, eventually we'll want to clean up the error
message.
Fixes#7047.
Historically, we'd just use the default Django version of this
function. However, since we did the big subdomains migration, it's
now the case that we have to pass in the subdomain to authenticate
(i.e. there's no longer a fallback to just looking up the user by
email).
This fixes a problem with user creation in an LDAP realm, because
previously, the user creation flow would just pass in the username and
password (after validating the subdomain).
I think an hour after signup is not the right time to try to get someone to
re-engage with a product.
This also makes the day1 email clearly a transactional email both in
experiencing the product and in the eyes of various anti-spam laws, and
allows us to remove the unsubscribe link.
This modifies the realm creation form to (1) support a
realm_in_root_domain flag and (2) clearly check whether the root
domain is available inside check_subdomain_available before trying to
create a realm with it; this should avoid IntegrityErrors.
We were doing an unnecessary database query on every user registration
checking the availability of the user's subdomain, when in fact this
is only required for realm creation.
This removes sender names from the message cache, since
they aren't guaranteed to be valid, and they're inexpensive
to add.
This commit will make the message cache entries smaller
by removing sender___full_name and sender__short_name
fields.
Then we add in the sender fields to the message payloads
by doing a query against the unique sender ids of the
messages we are processing.
This change leads to 2 extra database hops for most of
our message-related codepaths. The reason there are 2 hops
instead of 1 is that we basically re-calculate way too
much data to get a no-markdown dictionary.
This commit prepares us to introduce a StreamLite class. For
these tests, we don't care about the actual contents of the
Stream, just the right stream is there.
Create a new custom email backend which would automatically
logs the emails that are send in the dev environment as
well as print a friendly message in console to visit /emails
for accessing all the emails that are sent in dev environment.
Since django.core.mail.backends.console.EmailBackend is no longer
userd emails would not be printed to the console anymore.
These arguments are only intended to be used for realm creation, and
they make the code more confusing.
We need to make a few changes after doing this, because some tests
were relying on these extra arguments causing the form to not submit
for their error handling.
We don't apply these changes to the LDAP tests, since fixing those
seems complicated.
Previously, invitation reminder emails were only being cleared after a
successful signup if newsletter_data was available, since that was the
circumstance in which we were calling the relevant queue processor
code. Now, we (1) clear them when a human user finishes signing up
and (2) correctly clear them using the 'address' field of
ScheduleEmail, not user_id.
This commit makes get_recipient_info() faster by never creating
Django ORM objects. We use the ORM to create a values query
instead, and then we iterate over the rows to create various
collections of ids.
In order to avoid lots of code duplication, this commit unifies
how we query UserProfile for PMs and streams. Prior to this
commit we were getting "wide" UserProfile objects out of
our memcached cache. Now we just go to the database with our
list of userids. The new approach at worst adds one hop to the
database for PMs, which aren't really a performance bottleneck
(compared to streams). And the new approach actually saves a
hop when both partners aren't in cache (plus we don't pay the
penalty of hitting the cache itself).
The performance improvement here is easy to measure for messages
to streams with many users, even with all the other activity
that goes on inside do_send_messages(). I took test_performance()
in test_messages.py, set num_extra_users to 3000, and consistently
measured a ~20% speedup in do_send_messages().
This commit also eliminates fetching of emails. We probably
could have done that in a prior commit, but in this commit it
is very explicit that we don't need it. While removing email
from the query is a no-brainer, it actually had a negigible
impact on performance. Almost all the savings here comes from
not create UserProfile objects.
Usually a small minority of users are eligible to receive missed
message emails or mobile notifications.
We now filter users first before hitting UserPresence to find idle
users. We also simply check for the existence of recent activity
rather than borrowing the more complicated data structures that we
use for the buddy list.
Use this new variable to determine if the user already exists while
doing registration. While doing login through GitHub if we press
*Go back to login*, we pass email using email variable. As a result,
the login page starts showing the "User already exists error" if we
don't change the variable.
Previously, Zulip's server logs would not show which user or client
was involved in login or user registration actions, which made
debugging more annoying than it needed to be.
This should significantly improve the user experience for new users
signing up with GitHub/Google auth. It comes complete with tests for
the various cases. Further work may be needed for LDAP to not prompt
for a password, however.
Fixes#886.
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 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.
