Mateusz Mandera 4b567d8edd rate_limiter: Fix secs_to_freedom being set to a timestamp.
time_reset returned from api_calls_left() was a timestamp, but
mistakenly treated as delta seconds. We change the return value of
api_calls_left() to be delta seconds, to be consistent with the return
value of rate_limit().

Mateusz Mandera 0155193140 rate_limiter: Change type of the RateLimitResult.remaining to int.
This is cleaner than it being Optional[int], as the value of None for

Mateusz Mandera e86cfbdbd7 rate_limiter: Store data in request._ratelimits_applied list.
The information used to be stored in a request._ratelimit dict, but
there's no need for that, and a list is a simpler structure, so this
allows us to simplify the plumbing somewhat.

Mateusz Mandera 9911c6a0f0 rate_limiter: Put secs_to_freedom as message when raising RateLimited.
That's the value that matters to the code that catches the exception,
and this change allows simplifying the plumbing somewhat, and gets rid
of the get_rate_limit_result_from_request function.

Wyatt Hoodes 13f86f35d9 zcommand: Add `/fluid-width` and `/fixed-width` slash commands. 2020-04-07 20:54:34 -07:00
Wyatt Hoodes 4d6755a807 zcommand.py: Clean up backend logic.
This commit contains a few clean ups:

* In order to scale better for adding multiple commands,
the message formatting and setting switch logic was
extracted to its own function.

* The command lists were removed, as the frontend parses
the slash command from the compose box, and only sends
a single command to the backend for any given command
alias typed.

* The `switch_command` logic was removed because, given
the aforementioned fact, the index of the command will
always be the same. Thus the switch command will always
be the same.

* Switched to using early returns as opposed to nested
conditionals.  Along with removing single use variable
declarations.

Tim Abbott 843345dfee message_edit: Add backend for moving a topic to another stream.
This commit reuses the existing infrastructure for moving a topic
within a stream to add support for moving topics from one stream to
another.

Split from the original full-feature commit so that we can merge just
the backend, which is finished, at this time.

This is a large part of #6427.

The feature is incomplete, in that we don't have real-time update of
the frontend to handle the event, documentation, etc., but this commit
is a good mergable checkpoint that we can do further work on top of.
We also still ideally would have a test_events test for the backend,
but I'm willing to leave that for follow-up work.

This appears to have switched to tabbott as the author during commit
squashing sometime ago, but this commit is certainly:

Steve Howell 1ae07b93d8 presence: Simplify payload for webapp.
This changes the payload that is used
to populate `page_params` for the webapp,
as well as responses to the once-every-50-seconds
presence pings.

Now our dictionary of users only has these
two fields in the value:

    - activity_timestamp
    - idle_timestamp

Example data:

    {
        6: Object { idle_timestamp: 1585746028 },
        7: Object { active_timestamp: 1585745774 },
        8: Object { active_timestamp: 1585745578,
                    idle_timestamp: 1585745400}
    }

We only send the slimmer type of payload
to clients that have set `slim_presence`
to True.

Note that this commit does not change the format
of the event data, which still looks like this:

    {
        website: {
            client: 'website',
            pushable: false,
            status: 'active',
            timestamp: 1585745225
        }

This commit migrates zulip outging webhook payload to
/zulip-outgoing-webhook:post in OpenAPI.

Steve Howell f6503a4061 validation: Use JsonableError for extractors.
The distinction between ValueError and TypeError
is not useful in these functions:

    - extract_stream_indicator
    - extract_private_recipients (or its callees)

These are always invoked in views to validate
user input.

When we use REQ to wrap the validators, any
Exception gets turned into a JsonableError, so
the distinction is not important.

And if we don't use REQ to wrap the validators,
the errors aren't caught.

Now we just let these functions directly produce
the desired end result for both codepaths.

Also, we now flag the error strings for translation.

Tim Abbott e3a4aeeffa CVE-2020-9445: Remove unused and insecure modal_link feature.
Zulip's modal_link markdown feature has not been used since 2017; it
was a hack used for a 2013-era tutorial feature and was never used
outside that use case.

Unfortunately, it's sloppy implementation was exposed in the markdown
processor for all users, not just the tutorial use case.

More importantly, it was buggy, in that it did not validate the link
using the standard validation approach used by our other code
interacting with links.

The right solution is simply to remove it.

Udit107710 ef741bf317 messages: Return shallow copy of message object.
When more than one outgoing webhook is configured,
the message which is send to the webhook bot passes
through finalize_payload function multiple times,
which mutated the message dict in a way that many keys
were lost from the dict obj.

This commit fixes that problem by having
`finalize_payload` return a shallow copy of the
incoming dict, instead of mutating it.  We still
mutate dicts inside of `post_process_dicts`, though,
for performance reasons.

This was slightly modified by @showell to fix the
`test_both_codepaths` test that was added concurrently
to this work.  (I used a slightly verbose style in the
tests to emphasize the transformation from `wide_dict`
to `narrow_dict`.)

I also removed a deepcopy call inside
`get_client_payload`, since we now no longer mutate
in `finalize_payload`.

Finally, I added some comments here and there.

For testing, I mostly protect against the root
cause of the bug happening again, by adding a line
to make sure that `sender_realm_id` does not get
wiped out from the "wide" dictionary.

A better test would exercise the actual code that
exposed the bug here by sending a message to a bot
with two or more services attached to it.  I will
do that in a future commit.

Fixes #14384

Steve Howell 4c51a94bcd message: Move transitional shim for delivery email.
If we have an old event that's missing the field
`sender_delivery_email`, we now patch it at the top
of `process_message_event`, rather than for each call
to `get_client_payload`.  This will make an upcoming
commit a bit easier to reason about.  Basically, it's
simpler to shim the incoming event one time rather
than doing it up to four times.  We know that
`get_client_payload` is non-destructive, because it
does a deepcopy.

Steve Howell 8002f48099 tests: Validate payload in test_build_bot_request.
We now validate the message data explicitly, rather

event message data.  (We'll have a commit soon that
fixes a mutation-related bug.)

Steve Howell 50c197c1fc tests: Move bot event code out of setUp().

We've had a bug for a while that if any ScheduledEmail objects get

corrects the problem, they'll still get errors because of the objects
stored with the wrong format.

We solve this by using FromAddress placeholders strings in

setting the final `from_address` value when mail is actually sent

Steve Howell f62f8c9238 message tests: Clean up edit-message tests.
Overall, this change eliminates a lot of
optional parameters and conditionals, plus
some legacy logic related to caches.

For all the places we are just editing topics,
we now just call `check_topic` to see that
the topic got updated.

For places where the topic edit failed, we
just inline the checks that message still
has the old topic and content.

And then for successful **content** edits,
we now do a more rigorous, more sane check
that the messages are properly cached.  The
old code here had evolved from 2013 into
something that didn't really make much sense
in the context of editing topics.

Now we are literally pulling data from the
cache and making sure it's valid, rather
than trying to poorly simulate the two
codepaths related to dispatching message
events and fetching messages.  Some of the
history here was that when I introduced
`MessageDict` several years ago, I did a
lot of code sweeping and didn't analyze every
single test to make sure it's still valid,
plus some of the tests still had some value
for catching regressions.  A recent commit
now gets us coverage on that a lot more
explicitly, rather than in passing.

Steve Howell db4ae7fc39 tests: Test equivalency of the two message codepaths.
See the comment in the test for a thorough explanation.

In brief, this test makes sure that the events codepath

And this sets us up to simplify another test that kind
of poorly tried to do the same thing in passing.  (In
fairness the test was really ancient and preceded a lot
of later work that we did here.)

Steve Howell c2b3269420 message perf: Streamline stream name lookups.
When we are fetching messages, we need to hydrate
stream names into the messages for legacy reasons.

(Ideally, we could skip this step for the webapp
and modern mobile clients, since they really only
need stream_ids, but we're not there yet.)

We keep a recipient cache that maps recipient ids
to stream names.

When we populate that cache, we now use `values(...)`
to avoid fat objects and extra DB work.

Note that we are already using a similar technique
for hydrating PM/huddle recipients.

The previous system for documenting arguments was very ugly if any of

wrong design element to use for API parameters, and we'd be much
better off with individual card-type widgets instead.

This rewrites the API arguments documentation implementation to use a
basic sort of card-like system with some basic styling; I think the
result is a lot more readable, and it's a lot more clear how we would
add additional OpenAPI details (like parameter types) to the
documentation.

This is because the To: header on the received email corresponds
to the email list, and there are no other headers to indicate the
final recipient, apart from the "Envelope-To" header added by
Exim. To resolve this problem, the commit adds "Envelope-To" to
the list of headers to check for a match.

Dinesh f526ae9377 tests: Change `is_signup` argument to boolean in `test_auth_backends.py`.
The function `prepare_login_url_and_headers` returns a register
link for any value of `is_signup` unless it's not none.
This commit changes it to a boolean for that function and other
functions using it so that it becomes much clearer when a
register link will be returned.

Also, all occurrences of `is_signup='1'` are changed to
`is_signup=True` to make the code consistent with the above change.

Tim Abbott d9bb6d0081 compatibility: Add more strict desktop app blocking.
This allows us to block use of the desktop app with insecure versions

error page).

For now we block only versions that are known to be both insecure and
not auto-updating, but we can easily adjust these parameters in the
future.

fields missing from what modern Jira does) and we've seen it in
production.

The best we can do is encourage users to upgrade Jira for better data.

Instead of operating on RateLimitedObjects, and making the classes

Dinesh 5cb476e03d auth: Handle confirm registration page in `stage_two_of_registration`.
When a user in login flow using github auth chooses a email that is

of `stage_two_of_registration`.

Dinesh 3de646d2cf auth: Improve GitHub auth with multiple verified emails.
The previous model for GitHub authentication was as follows:

* If the user has only one verified email address, we'll generally just log them in to that account
* If the user has multiple verified email addresses, we will always
  prompt them to pick which one to use, with the one registered as
  "primary" in GitHub listed at the top.

This change fixes the situation for users going through a "login" flow
(not registration) where exactly one of the emails has an account in
the Zulip oragnization -- they should just be logged in.

Fixes part of #12638.

Steve Howell a041d9e4aa minor: Clean up lstrip() for help article titles.
Saying `foo.lstrip('# ')` does more than just remove
a '# ' prefix.  It removes any combination of '#' and
spaces.

We now make the intention slightly more clear.

We would strip these as you'd expect:

    # foo
    ## foo
    ### foo

but for this we now only strip the first "#":

    # # # # # foo

Steve Howell edf1b1e5e8 minor: Fix buggy lstrip() call in integrations dev panel.
Thanks to @minusworld for catching this--see #14264, which

might tell you it does.

Now we properly remove the "HTTP_" prefix.

It's not clear to me why we need these prefixes for Django
purposes in the fixtures, but I didn't want to go down
the rabbit hole of fixing those.

To test:

    got to http://YOUR-DEV_SERVER/devtools/integrations/
    select "bitbucket3" for the integration.
    select "diagnostics_ping.json" for the fixture.
    see "X_EVENT_KEY" in "Custom HTTP Headers"

Steve Howell b5cba4aafe test_narrow: Use tuple unpacking to get messages.

Steve Howell ef772ee12f bot events: Prevent duplicate add-bot notifications.
We don't need `do_create_user` to send a partial
event here for bots.  The only caller to `do_create_user`
that actually creates bots (apart from some tests that
just need data setup) is `add_bot_backend`, which
sends the more complete event including bot "extras"
like service info.

The modified event tests show the simplification
here (2 events instead of 3).

Also, the bot tests now use tuple unpacking, which
will force a ValueError if we duplicate events
again.

Steve Howell eb9a252ec9 populate_db, tests: Restrict emails in zulip realm.
We now restrict emails on the zulip realm, and now
`email` and `delivery_email` will be different for
users.

This change should make it more likely to catch
errors where we leak delivery emails or use the
wrong field for lookups.

Steve Howell f647587675 bulk_create: Handle realms that hide delivery emails. 2020-03-19 16:04:05 -07:00
Steve Howell ecbbc3e365 performance: Simplify bulk_create_users().
We were going back to the database to get all
the users in the realm, when we had them right
there already.  I believe this is a legacy
of us running on a very old version of Django
(back in early days), where `bulk_create`
didn't give you back ids in a nice way.

In the interim we added the `RealmAuditLog`
code, which does take advantage of the
existing profiles (and proves we can rely
on them).

But meanwhile we were still
doing a query to get all N users in the
realm.  With `selected_related`!

To be fair, bulk_create_users() is by
its very nature a pretty infrequent
operation.  This change is more motivated
by code cleanup.

Now we just loop through user_ids for
the Recipient/Subscriber foreign key rows.

I also removed some fairly convoluted code mapping
emails to user_ids and just work in user_id
space.
2020-03-19 16:04:05 -07:00
Steve Howell 1306239c16 tests: Use email/delivery_email more explicitly.
We try to use the correct variation of `email`
or `delivery_email`, even though in some
databases they are the same.

(To find the differences, I temporarily hacked
populate_db to use different values for email
and delivery_email, and reduced email visibility
in the zulip realm to admins only.)

In places where we want the "normal" realm
behavior of showing emails (and having `email`
be the same as `delivery_email`), we use
the new `reset_emails_in_zulip_realm` helper.

A couple random things:

    - I fixed any error messages that were leaking
      the wrong email

    - a test that claimed to rely on the order
      of emails no longer does (we sort user_ids
      instead)

    - we now use user_ids in some place where we used
      to use emails

    - for IRC mirrors I just punted and used
      `reset_emails_in_zulip_realm` in most places

    - for MIT-related tests, I didn't fix email
      vs. delivery_email unless it was obvious

I also explicitly reset the realm to a "normal"
realm for a couple tests that I frankly just didn't
have the energy to debug.  (Also, we do want some
coverage on the normal case, even though it is
"easier" for tests to pass if you mix up `email`
and `delivery_email`.)

In particular, I just reset data for the analytics
and corporate tests.

Steve Howell b1f8141200 tests: Prevent false positives for duplicate signups.

Steve Howell ca74cd6e37 bug fix: Fix unread counts for certain API messages.
If I send a message from a normal Zulip client, it is
considered to be "read" by me.  But if I send it via
an API program (using my human account), the message
is not immediately "read" by me.

Now we handle this correctly in `get_raw_unread_data`.

The symptom of this was that these messages would get
"stuck" in "Private Messages" narrows until the next
time you reloaded your app.

This security improvement only impacts a single installation of Zulip
where Zephyr mirroring is in use that has already had the fix applied,
so there's no reason to do a security notice for it.

Steve Howell fcc5ae5247 invites: Fix regression w/email vs. delivery_email.
In 220c2a5ff3 I
introduced a query to find invites by delivery_email

For most realms `email` and `delivery_email` are
synonymous, so this temporary bug would not affect
them.  For realms that restrict emails, the invite
would have probably failed for other reasons, but
the symptom would have been less clear.

We now have this API...

user:

    self.login('hamlet')

If you're gonna use the user in the
rest of the test:

    hamlet = self.example_user('hamlet')
    self.login_user(hamlet)

If you are specifically testing
email/password logins (used only in 4 places):

    self.login_by_email(email, password)

And for failures uses this (used twice):

Steve Howell c235333041 test performance: Pass in users to api_* helpers.
This reduces query counts in some cases, since
we no longer need to look up the user again. In
particular, it reduces some noise when we
count queries for O(N)-related tests.

The query count is usually reduced by 2 per
API call.  We no longer need to look up Realm
and UserProfile.  In most cases we are saving
these lookups for the whole tests, since we
usually already have the `user` objects for
other reasons.  In a few places we are simply
moving where that query happens within the
test.

In some places I shorten names like `test_user`
or `user_profile` to just be `user`.
2020-03-11 14:18:29 -07:00
Steve Howell 626ad0078d tests: Add uuid_get and uuid_post.
We want a clean codepath for the vast majority
of cases of using api_get/api_post, which now
uses email and which we'll soon convert to
accepting `user` as a parameter.

These apis that take two different types of
values for the same parameter make sweeps
like this kinda painful, and they're pretty
easy to avoid by extracting helpers to do
the actual common tasks.  So, for example,
here I still keep a common method to
actually encode the credentials (since
the whole encode/decode business is an
annoying detail that you don't want to fix
in two places):

    def encode_credentials(self, identifier: str, api_key: str) -> str:
        """
        identifier: Can be an email or a remote server uuid.
        """
        credentials = "%s:%s" % (identifier, api_key)
        return 'Basic ' + base64.b64encode(credentials.encode('utf-8')).decode('utf-8')

But then the rest of the code has two separate
codepaths.

And for the uuid functions, we no longer have
crufty references to realm.  (In fairness, realm
will also go away when we introduce users.)

For the `is_remote_server` helper, I just inlined
it, since it's now only needed in one place, and the
name didn't make total sense anyway, plus it wasn't
a super robust check.  In context, it's easier
just to use a comment now to say what we're doing:

    # If `role` doesn't look like an email, it might be a uuid.
    if settings.ZILENCER_ENABLED and role is not None and '@' not in role:
        # do stuff

Mateusz Mandera 89394fc1eb middleware: Use request.user for logging when possible.
Instead of trying to set the _requestor_for_logs attribute in all the
relevant places, we try to use request.user when possible (that will be
when it's a UserProfile or RemoteZulipServer as of now). In other
places, we set _requestor_for_logs to avoid manually editing the
request.user attribute, as it should mostly be left for Django to manage
it.
In places where we remove the "request._requestor_for_logs = ..." line,
it is clearly implied by the previous code (or the current surrounding
code) that request.user is of the correct type.

Tim Abbott ccf63ac66b decorators: Restructure get_client_name interface.
Previously, get_client_name was responsible for both parsing the
User-Agent data as well as handling the override behavior that we want
to use "website" rather than "Mozilla" as the key for the Client object.

Now, it's just responsible for User-Agent, and the override behavior
is entirely within process_client (the function concerned with Client
objects).

This has the side effect of changing what `Client` object we'll use
for HTTP requests to /json/ endpoints that set the `client` attribute.
I think that's in line with our intent -- we only have a use case for
API clients overriding the User-Agent parsing (that feature is a
workaround for situations where the third party may not control HTTP
headers but does control the HTTP request payload).

This loses test coverage on the `request.GET['client']` code path; I
disable that for now since we don't have a real use for that behavior.

(We may want to change that logic to have Client recognize individual
browsers; doing so requires first using a better User-Agent parsing
library).

API, so this sets up a more effective test.  It also allows us to
remove certain Client parsing logic for the /json/ views using session
authentication.

Mateusz Mandera fe0f381914 populate_db: Don't restrict email domains by default in tests and dev.
The email domain restriction to @zulip.com is annoying in development
environment when trying to test sign up. For consistency, it's best to
have tests use the same default, and the tests that require domain
restriction can be adjusted to set that configuration up for themselves
explicitly.

Tim Abbott 5835023021 tests: Use user IDs internally in send message helpers.
This uses the better, modern, user ID based API for sending messages
internally in the test suite, something that's convenient to do as a
follow-up to the migration to pass UserProfile objects to these
functions.

Steve Howell 5e2a32c936 tests: Use users in send_*_message.
This commit mostly makes our tests less
noisy, since emails are no longer an important
detail of sending messages (they're not even
really used in the API).

It also sets us up to have more scrutiny
on delivery_email/email in the future
for things that actually matter.  (This is
a prep commit for something along those
lines, kind of hard to explain the full
plan.)

Vishnu KS 1c6435d4cc validator: Optionally record a type_structure attribute.
We plan to use these records to check and record the schema of Zulip's
events for the purposes of API documentation.

Based on an original messier commit by tabbott.

In theory, a nicer version of this would be able to work directly off
the mypy type system, but this will be good enough for our use case.

Tim Abbott 9230213bde settings: Add EMAIL_ADDRESS_VISIBILITY_NOBODY.
This extends our email address visibility settings to deny access to
user email addresses even to organization administrators.

At the moment, they can of course change the setting (which leaves an
audit trail), but in the future only organization owners will be able
to change that setting.

While we're at this, we rewrite the settings_data.js test to cover all
the cases in a more consistent way.

Fixes #14111.

Tim Abbott 914cda9e2d test_classes: Fix api credentials with email_address_visibility setting.
This isn't the only bug in our testing libraries with
EMAIL_ADDRESS_VISIBILITY; but we don't have a lot of tests that need
to deal with that set of settings.

Steve Howell 1b4cac6734 models: Cache failures to find user in get_user_by_api_key.
We will cache failed lookups with None.  The
use case here is that broken API clients may
continually ask for the same wrong API key, and
we want to handle that as quickly as possible.

Steve Howell f2b8eef21a refactor: Avoid hacky use of ValidationError.code.
We were using `code` to pass around messages.

The `code` field is designed to be a code, not
a human-readable message.

It's possible that we don't actually need two
flavors of messages for these type of validations,
but I didn't want to change that yet.

We **definitely** don't need to put two types of
message in the exception, so I fix that.  Instead,
I just have the caller ask what level of detail
it needs.

I added a non-verbose message for the case of
system bots.

I removed the non-translated version of the message
for deactivated accounts, which didn't have test
coverage and is slightly more prone to leaking
email info that we don't want to leak.
2020-03-06 11:53:22 -08:00
Steve Howell 62fb3ad801 refactor: Move validate_email_not_already_in_realm.
We move this to email_validation.py.

Steve Howell 7e55cab429 invite performance: Reduce queries to find existing users.
In the prep commits leading up to this, we split
out two new helpers:

    validate_email_is_valid
    get_errors_for_new_emails

Now when we validate invites we use two separate
loops to filter our emails.

Note that the two extracted functions map to two
of the data structures that used to be handled
in a single loop, and now we break them out:

    errors = validate_email_is_valid
    skipped = get_errors_for_new_emails

The first loop checks that emails are even valid
to begin with.

The second loop finds out whether emails are already
in use.

The second loop takes advantage of this helper:

    get_errors_for_new_emails

The second helper can query all potential new emails
with a single round trip to the database.

This reduces our query count.
2020-03-06 11:53:22 -08:00
Steve Howell 220c2a5ff3 performance: Add get_users_by_delivery_email().
The main purpose of this new function is to allow
us to validate emails in bulk, which we don't do
yet (still setting the stage for that).

This is still a speedup, though, since in our
caller we grab only three fields now.

And other than that, we're essentially doing
the same query for the single-email case, just
outside the loop.
2020-03-06 11:53:22 -08:00
Steve Howell b35ffde5fb tests: Avoid calling actions.validate_email().
We are trying to kill off `validate_email`, so
we no longer call it from these tests.

These tests are already kind of low-level in
nature, so testing the more specific helpers
here should be fine.

Note that we also make the third parameter
to `validate_email` non-optional in this commit,
to preserve 100% coverage.  This is really just
refactoring noise--we will soon eliminate the
entire function, but I didn't want to do everything
in a huge commit.
2020-03-06 11:53:22 -08:00
Steve Howell 6f62c993a6 refactor: Extract get_existing_user_errors.
This is a prep commit that will allow us
to more efficiently validate a bunch of
emails in the invite UI.

This commit does not yet change any
behavior or performance.

A secondary goal of this commit is to
prepare us to eliminate some hackiness
related to how we construct
`ValidationError` exceptions.

It preserves some quirks of the prior
implementation:

   - the strings we decided to translate
     here appear haphazard (and often
     get ignored anyway)

   - we use `msg` in most codepaths,
     but use `code` for invites

Right now we never actually call this with
more than one email, but that will change
soon.

Note that part of the rationale for the inner
method here is to avoid a test coverage bug
with `continue` in loops.
2020-03-06 11:53:22 -08:00
Steve Howell ad85e286de user settings: Inline call to validate_email.
We are trying to elminate the version of
`validate_email` that lives in `actions.py`.

Inlining it barely increases the code size, and
it removes some noise related the three-item
tuple that `check_incoming_email` returns.
2020-03-06 11:53:22 -08:00
Steve Howell 689aca9140 refactor: Extract validate_email_is_valid().
This has two goals:

    - sets up a future commit to bulk-validate
      emails

    - the extracted function is more simple,
      since it just has errors, and no codes
      or deactivated flags

This commit leaves us in a somewhat funny
intermediate state where we have
`action.validate_email` being a glorified
two-line function with strange parameters,
but subsequent commits will clean this up:

    - we will eliminate validate_email
    - we will move most of the guts of its
      other callee to lib/email_validation.py

To be clear, the code is correct here, just
kinda in an ugly, temporarily-disorganized
intermediate state.

Steve Howell 30b43605c3 invite performance: Reduce RealmDomain queries.
We now use the `get_realm_email_validator()`
helper to build an email validator outside
the loop of emails in our invite list.

This allows us to perform RealmDomain queries
only once per request, instead of once per
email.
2020-03-06 11:53:22 -08:00
Steve Howell ce8f6797c7 performance: Optimize get_realm_email_validator.
We now query RealmDomain objects up front.  This
change is minor in most circumstances--it sometimes
saves a round trip to the database; other times,
it actually brings back slightly more data
(optimistically).

The big win will come in a subsequent commit,
where we avoid running these queries in a loop
for every callback.

Note that I'm not sure if we intentionally
omitted checks for emails with "+" in them
for some circumstances, but I just preserved
the behavior.
2020-03-06 11:53:22 -08:00
Steve Howell ddbc536739 refactor: Extract get_realm_email_validator.
This change sets us up to use the same realm
data for multiple email validations.
2020-03-06 11:53:22 -08:00
Steve Howell 57f1aa722c refactor: Rename validate_email_for_realm.
Now called:

    validate_email_not_already_in_realm

We have a separate validation function that
makes sure that the email fits into a realm's
domain scheme, and we want to avoid naming
confusion here.

Steve Howell c43a29ff54 invites: Fix bug with inviting cross realm bots.
Without the fix here, you will get an exception
similar to below if you try to invite one of the
cross realm bots.  (The actual exception is
a bit different due to some rebasing on my branch.)

	  File "/home/zulipdev/zulip/zerver/lib/request.py", line 368, in _wrapped_view_func
		return view_func(request, *args, **kwargs)
	  File "/home/zulipdev/zulip/zerver/views/invite.py", line 49, in invite_users_backend
		do_invite_users(user_profile, invitee_emails, streams, invite_as)
	  File "/home/zulipdev/zulip/zerver/lib/actions.py", line 5153, in do_invite_users
		email_error, email_skipped, deactivated = validate_email(user_profile, email)
	  File "/home/zulipdev/zulip/zerver/lib/actions.py", line 5069, in validate_email
		return None, (error.code), (error.params['deactivated'])
	TypeError: 'NoneType' object is not subscriptable

Obviously, you shouldn't try to invite a cross
realm bot to your realm, but we want a reasonable
error message.

RESOLUTION:

Populate the `code` parameter for `ValidationError`.

BACKGROUND:

Most callers to `validate_email_for_realm` simply catch
the `ValidationError` and then report a more generic error.

That's also what `do_invite_users` does, but it has the
somewhat convoluted codepath through `validate_email`
that triggers this code:

    try:
        validate_email_for_realm(user_profile.realm, email)
    except ValidationError as error:
        return None, (error.code), (error.params['deactivated'])

The way that we're using the `code` parameter for
`ValidationError` feels hacky to me.  The intention
behind `code` is to provide a descriptive error to
calling code, and it's not intended for humans, and
it feels strange that we actually translate this in
other places.  Here are the Django docs:

    https://docs.djangoproject.com/en/3.0/ref/forms/validation/

And then here's an example of us actually translating
a code (not part of this commit, just providing context):

    raise ValidationError(_('%s already has an account') %
                          (email,), code = _("Already has an account."),
                          params={'deactivated': False})

Those codes eventually get put into InvitationError, which
inherits from JsonableError, and we do actually display
these errors in the webapp:

    if skipped and len(skipped) == len(invitee_emails):
        # All e-mails were skipped, so we didn't actually invite anyone.
        raise InvitationError(_("We weren't able to invite anyone."),
                              skipped, sent_invitations=False)

I will try to untangle this somewhat in upcoming commits.
