Add new rest api endpoint GET users/{email} for looking up a user by
email, which is useful especially for corporate API applications that
might already have a user's email address.
Fixes#14302.
zerver/lib/users.py has a function named access_user_by_id, which is
used in /users views to fetch a user by it's id. Along with fetching
the user this function also does important validations regarding
checking of required permissions for fetching the target user.
In an attempt to solve the above problem this commit introduces
following changes:
1. Make all the parameters except user_profile, target_user_id
to be keyword only.
2. Use for_admin parameter instead of read_only.
3. Adds a documentary note to the function describing the reason for
changes along with recommended way to call this function in future.
4. Changes in views and tests to call this function in this changed
format.
Changes were tested using ./tools/test-backend.
Fixes#17111.
Adjustments made due to changes in Django 3.0:
(https://docs.djangoproject.com/en/3.0/releases/3.0/)
- test_signup: INTERNAL_RESET_URL_TOKEN was moved to
PasswordResetConfirmView.reset_url_token
- test_message_fetch:
"add_never_cache_headers() and never_cache() now add the private
directive to Cache-Control headers."
- "django.utils.html.escape() now uses html.escape() to escape HTML.
This converts ' to ' instead of the previous equivalent decimal
code '." - this requires adjusting the expected decimal code
in some of the string fixtures in tests.
By moving the relevant logic from realm.get_bot_domain to
get_fake_email_domain we will make realm.host be used (if possible) for
dummy user addresses. That is, instead of user11@zulipchat.com, the
address will become user11@subdomain.zulipchat.com.
Allowing any admins to create arbitrary users is not ideal because it
can lead to abuse issues. We should require something stronger that
requires the server operator's approval and thus we add a new
can_create_users permission.
In 709493cd75 (Feb 2017)
I added code to render_markdown that re-fetched the
sender of the message, to detect whether the message is
a bot.
It's better to just let the ORM fetch this. The
message object should already have sender.
The diff makes it look like we are saving round trips
to the database, which is true in some cases. For
the main message-send codepath, though, we are only
saving a trip to memcached, since the middleware
will have put our sender's user object into the
cache. The test_message_send test calls internally
to check_send_stream_message, so it was actually
hitting the database in render_markdown (prior to
my change).
Before this change we were clearing the cache on
every SQL usage.
The code to do this was added in February 2017
in 6db4879f9c.
Now we clear the cache just one time, but before
the action/request under test.
Tests that want to count queries with a warm
cache now specify keep_cache_warm=True. Those
tests were particularly flawed before this change.
In general, the old code both over-counted and
under-counted queries.
It under-counted SQL usage for requests that were
able to pull some data out of a warm cache before
they did any SQL. Typically this would have bypassed
the initial query to get UserProfile, so you
will see several off-by-one fixes.
The old code over-counted SQL usage to the extent
that it's a rather extreme assumption that during
an action itself, the entries that you put into
the cache will get thrown away. And that's essentially
what the prior code simulated.
Now, it's still bad if an action keeps hitting the
cache for no reason, but it's not as bad as hitting
the database. There doesn't appear to be any evidence
of us doing something silly like fetching the same
data from the cache in a loop, but there are
opportunities to prevent second or third round
trips to the cache for the same object, if we
can re-structure the code so that the same caller
doesn't have two callees get the same data.
Note that for invites, we have some cache hits
that are due to the nature of how we serialize
data to our queue processor--we generally just
serialize ids, and then re-fetch objects when
we pop them off the queue.
During the new user creation code path, there can be no existing
active clients for the user being created, so we can skip the code to
send events to that user's clients.
The tests here reflect that we need to send fewer events, and do fewer
queries that would have been spent computing data for these..
Fixes#16503, combined with the long series of recent changes by Steve
Howell to fix super-linear behavior in this code path.
We no bulk up peer_add/peer_remove events by user if the
same user has subscribed to multiple streams (and just
that single user).
This mostly optimizes the new-user codepath, but the
algorithm is a bit more general in nature.
This test was flaky due to some date-related
non-determinism. I make all the Message objects
current to make add_new_user_history reliably
try to bulk-update UserMessage rows to read.
The main race conditions, which actually happened in production was with
concurrent execution of deliver_email and clear_scheduled_emails.
clear_scheduled_emails could delete all email.users in the middle of
deliver_email execution, causing it to pass empty to_user_ids list to
send_email. We mitigate this by getting the list of user ids in a single
query and moving forward with that snapshot, not having to worry about
database data being mutated anymore.
clear_scheduled_emails had potential race conditions with concurrent
execution of itself due to not locking the appropriate rows upon
selecting them for the purpose of potentially deleting them. FOR UPDATE
locks need to be acquired to prevent simultaneous mutation.
Tested manually with some print+sleep debugging to make some races
happen.
fixes #zulip-2k (sentry)
This adds 'user_id' to the simple success response for 'POST /users'
api endpoint, to make it convenient for API clients to get details
about users they just created. Appropriate changes have been made in
the docs and test_users.py.
Fixes#16072.
Now, gather_subscriptions include web-public streams in the 3 sets
of streams that it returns, subscribed, unsubscribed and never
subscribed.
This is part of PR #14638 that aims to allow guest users to browse and
subscribe to web-public streams.
A few major themes here:
- We remove short_name from UserProfile
and add the appropriate migration.
- We remove short_name from various
cache-related lists of fields.
- We allow import tools to continue to
write short_name to their export files,
and then we simply ignore the field
at import time.
- We change functions like do_create_user,
create_user_profile, etc.
- We keep short_name in the /json/bots
API. (It actually gets turned into
an email.)
- We don't modify our LDAP code much
here.
When you post to /json/users, we no longer
require or look at the short_name parameter,
since we don't use it in any meaningful way.
An upcoming commit will eliminate it from the
database.
There is still some miscellaneous cleanup that
has to happen for things like analytics queries
and dead code in node tests, but this should
remove the main use of pointers in the backend.
(We will also still need to drop the DB field.)
We've been seeing an exception in server_event_dispatch.js in
production where in large organizations, sometimes when a new user
joined, every other browser in the organization would throw an
exception processing some sort of realm_user/update event.
It turns out the cause was that when a user copies their profile from
an existing user account with a user-uploaded avatar, the code path we
reused to set the avatar properly send a realm_user/update event about
the avatar change -- for a user that hadn't been fully created and
certainly hadn't have the realm_user/add event sent for.
We fix this and add tests and comments to prevent it recurring.
(Removed an incorrect docstring while working on this).
With this implementation of the feature of the automatic theme
detection, we make the following changes in the backend, frontend and
documentation.
This replaces the previous night_mode boolean with an enum, with the
default value being to use the prefers-color-scheme feature of the
operating system to determine which theme to use.

Old: a validator returns None on success and returns an error string
on error.
New: a validator returns the validated value on success and raises
ValidationError on error.
This allows mypy to catch mismatches between the annotated type of a
REQ parameter and the type that the validator actually validates.

Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.
Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start. I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

This new endpoint returns a 'user' dictionary which, as of now,
contains a single key 'is_subscribed' with a boolean value that
represents whether the user with the given 'user_id' is subscribed
to the stream with the given 'stream_id'.
Fixes#14966.
This commit adds some basic checks while adding or removing
realm owner status of a user and adds code to change owner
status of a user using update_user_backend.
This also adds restriction on removing owner status of the
last owner of realm. This restriction was previously on
revoking admin status, but as we have added a more privileged
role of realm owner, we now have this restriction on owner
instead of admin.
We need to apply that restriction both in the role change code path
and the deactivate code path.
We're migrating to using the cleaner zulip.com domain, which involves
changing all of our links from ReadTheDocs and other places to point
to the cleaner URL.
This commit removes short_name and client_id fields from the user
objects returned by get_profile_backend because neither of them
had a purpose.
* short_name hasn't been present anywhere else in the Zulip API for
several years, and isn't set through any coherent algorithm.
* client_id was a forgotten 2013-era predecessor to the queue_id field
returned by the register_event_queue process.
The combination of these changes gets us close to having `get_profile`
have the exact same format as other endpoints fetching a user object.
This commit changes get_profile_backend to be based on format_user_row
such that it's a superset of the fields for our other endpoints for
getting data on a user.
To be clear, this does not removes any of the exisiting fields, that
were returned by this endpoint.
This change adds some fields to the User object returned by the
endpoint. API docs are updated accordingly for the added fields.

This commit fixes the tests to use role instead of is_admin in
update user endpoint. These changes got missed in the original
commit 9fa6067 which included the change of using role in update user
endpoint and were also not caught in tests.
