Mateusz Mandera fe33966642 sessions: Implement the concept of expirable session variables.
This can be useful in the future for various things, and right now it'll
specifically be used in the signup mobile/desktop flows.

Hashir Sarwar eb23c6fa6c test_fixtures: Clean up interface for `template_database_status()`.
1) Created a new class `DatabaseType` and access its objects inside
`template_database_status()` instead of sending five arguments with
default values.

2) Made `check_files` and `setting_name` local variables instead of
function parameters since they had same value(None) for every call.

Fixes #13845.

Anders Kaseorg e257253e64 emoji_codes: Replace JS module with JSON module.
webpack optimizes JSON modules using JSON.parse("{…}"), which is
faster than the normal JavaScript parser.

Update the backend to use emoji_codes.json too instead of the three
separate JSON files.

Tim Abbott cb2c96f736 test_templates: Remove shallow template rendering code.
This code was very useful when first implemented to help catch errors
where our backend templates didn't render, but has been superceded by
the success of our URL coverage testing (which ensures every URL
supported by Zulip's urls.py is accessed by our tests, with a few
exceptions) and other tests covering all of the emails Zulip sends.

It has a significant maintenance cost because it's a bit hacky and
involves generating fake context, so it makes sense to remove these.
Any future coverage issues with templates should be addressed with a
direct test that just accessing the relevant URL or sends the relevant
email.

Mateusz Mandera 2475adbf8a messages_for_topic: Use stream.recipient_id for more efficient query. 2020-02-11 17:39:43 -08:00
Steve Howell 900f98c0c5 presence: Use realm_id for UserPresence queries.
We now use realm_id for querying UserPresence
instead of building a big WHERE clause from the
list of user_ids.

This commit may be a bit hard to measure, since
we still get the list of user_ids for the PushToken
query in the same method.

Tim Abbott fcac3a4342 recipients: Rename extract_recipients to extract_private_recipients.
Recent changes mean this function is now only used for private

Steve Howell 1b6578cafd messages: Fix bug with commas in stream names.
We now validate streams with a separate
function from PM recipients.

It's confusing enough all the ways you can
encode a stream or encode the PM recipients,
but trying to do it all in one function was
hard to reason about and led to at least one
bug.

In particular, there was a bug where streams
with commas in them would get split.  Now
we just don't ever split on commas inside
of `extract_stream_indicator`.

Fixes #13836

Steve Howell 96132fe0e9 extract_recipients: Enforce str as incoming type.
After removing internal_send_message() in a recent
commit, we now have only two callers for
extract_recipients, and they are both related
to our REQ mechanism that always passes strings
to converters.  (If there are default values,
REQ does not call the converters.)

We therefore make two changes:

    - use the more strict annotation of "str"
      for the `s` parameter

    - don't bother with the isinstance check

Steve Howell 8c3eaeb872 Remove obsolete internal_send_messages().

Steve Howell e37d660d19 error_notify: Use internal_send_stream_message(). 2020-02-11 12:20:53 -08:00
Steve Howell c4e3cfebb0 presence: Add realm_id to UserPresence.
This index is intended to optimize the performance of the very
frequently run query of "what is the presence status of all users in a
realm?".

Main changes:
    - add realm_id to UserPresence
    - add index for realm_id
    - backfill realm_id for old rows
    - change all writes to UserPresence to include
      realm_id

The index is of this form:

    "zerver_userpresence_realm_id_5c4ef5a9" btree (realm_id)

We will create an index on (realm_id, timestamp) in a
future commit, but I think it's a bit faster if you do
the backfill before the index.

There's also a minor tweak to the populate_db script.

Steve Howell 28a8ffbc4c email_mirror: Use internal_send_stream_message().
This is just a refactoring to the more modern API
for sending internal messages.

To make this work we now plumb the email_gateway
flag through `internal_send_stream_message` instead
of `internal_send_message`.

We also change `send_zulip` to have its callers
pass in a full UserProfile object (which one of
them already had).
2020-02-10 15:45:13 -08:00
Steve Howell 6922eef380 signups: Use internal_send_stream_message().
We prefer this to internal_send_message().

We are trying to deprecate `internal_send_message`,
which has extra moving parts related to
`extract_recipients` and `Addressee.legacy_build`.

There are two chunks of code that I touch here
that look pretty similar, but I'm not quite
sure they're worth de-duplicating, since they
use different topics and different message
content.

Steve Howell b33552997e cross realm bots: Simplify notify_new_user.
Instead of having `notify_new_user` delegate
all the heavy lifting to `send_signup_message`,
we just rename `send_signup_message` to be
`notify_new_user` and remove the one-line
wrapper.

We remove a lot of obsolete complexity:

    - `internal` was no longer ever set to True
      by real code, so we kill it off as well
      as well as killing off the internal_blurb code
      and the now-obsolete test

    - the `sender` parameter was actually an
      email, not a UserProfile, but I think
      that got past mypy due to the caller
      passing in something from settings.py

    - we were only passing in NOTIFICATION_BOT
      for the sender, so we just hard code
      that now

    - we eliminate the verbose
      `admin_realm_signup_notifications_stream`
      parameter and just hard code it to
      "signups"

    - we weren't using the optional realm
      parameter

There's also a long ugly comment in
`get_recipient_info` related to this code
that I amended for now.
We should try to take action in a subsequent
commit.

Hashir Sarwar dcbd3e486f stream_subscription: Remove unused TypedDict `SubInfo`. 2020-02-10 14:04:22 -08:00
Steve Howell 2ff41bf9e5 /json/users: Use field.realm for realm lookup.
This avoids an unnecessary join to UserProfile.

To verify this, you can do `print(queries)` in the
`test_get_custom_profile_fields_from_api` test.  It's
kinda noisy, so I excerpted them below...

Before:

    SELECT ...
    FROM "zerver_customprofilefieldvalue"
    INNER JOIN "zerver_userprofile" ON ("zerver_customprofilefieldvalue"."user_profile_id" = "zerver_userprofile"."id")
    INNER JOIN "zerver_customprofilefield" ON ("zerver_customprofilefieldvalue"."field_id" = "zerver_customprofilefield"."id")
    WHERE "zerver_userprofile"."realm_id" = 2

After:

    SELECT ...
    FROM "zerver_customprofilefieldvalue"
    INNER JOIN "zerver_customprofilefield" ON ("zerver_customprofilefieldvalue"."field_id" = "zerver_customprofilefield"."id")
    WHERE "zerver_customprofilefield"."realm_id" = 2'

I don't have any way to measure the two queries with
realistic data, but I would assume the second
query is significantly faster on most of our instances,
since CustomProfileField should be tiny.

Steve Howell 01f180d042 minor: Remove unused line of code in get_raw_user_data().
The line removed here is a noop, as both sides of the
immediately following conditional reassign the
same variable.

This harmless cruft was the result of the recent commit
1ae5964ab8, which added
support for single-user GETs.

Tim Abbott 84edb5c516 test_fixtures: Fix buggy reuse of status_dir between databases.
Apparently, the arguments passed to template_database_status were
incorrect for the manual testing development database, in that we
didn't pass a status_dir when calling into that code from provision.

The result was that provisioning before running `test-backend` would
ignore changes to the list of check_files (etc.) made after rebasing,
and vice versa.

The cleanest fix is to compute status_dir from other values passed in;
I'm also going to open a follow-up issue for creating a better overall
interface here.

akashaviator 1ae5964ab8 api: Add an api endpoint for GET /users/{id}

2020-02-07 10:36:31 -08:00
Steve Howell 7e99e7feb2 presence: Extract get_legacy_user_info.
This code is a bit flatter and just preps the data
for a single user.  There is never any interaction
between the data for user A and user B, so we can
mostly avoid complicated nested data structures
and do most of the data-crunching on a per-user basis.

We also do an explicit sort of the data before
running it through groupby.  The explicit sort
simplifies how we calculate `most_recent_info`
and also avoids needing to add `dt` to an intermediate
data structure.

Finally, when it comes to the individual client data,
the code has relied on the assumption that there is
only one row per client, which I believe to be true,
but now the code is more explicit about that.

Ryan Rehman 174b2abcfd settings: Migrate to stream_post_policy structure.
This commit includes a new `stream_post_policy` setting,
by replacing the `is_announcement_only` field from the Stream model,
which is done by mirroring the structure of the existing
`create_stream_policy`.

It includes the necessary schema and database migrations to migrate
the is_announcement_only boolean field to stream_post_policy,
a smallPositiveInteger field similar to many other settings.

This change is done to allow organization administrators to restrict
new members from creating and posting to a stream. However, this does
not affect admins who are new members.

With many tweaks by tabbott to documentation under /help, etc.

A few changes were made while extracting it:

* Renaming the UserProfile argument to acting_user, so we can do loops
  over a local user_profile variable.
* Moved it to zerver.lib.users, as that's a more appropriate home for
  this function formatting data on users.

* Simplified the calling convention for passing custom profile fields
  to reflect the fact that this function processes a single user (and
  is expected to be called in a loop).

"Zulip Voyager" was a name invented during the Hack Week to open

a Star Trek pun on the code it was based on, "Zulip Enterprise".

At the time, we just needed a name quickly, but it was never a good
name, just a placeholder.  This removes that placeholder name from
much of the codebase.  A bit more work will be required to transition
the `zulip::voyager` Puppet class, as that has some migration work
involved.

Tim Abbott 05108760f6 narrow: Add support for passing oldest/newest for anchor.
A wart that has long been present inin Zulip's get_messages API is how
to request "the latest messages" in the API.  Previously, the
recommendation was basically to pass anchor=10000000000000000 (for an
appropriately huge number). An accident of the server's implementation
meant that specific number of 0s was actually important to avoid a
buggy (or at least wasteful) value of found_newest=False if the query
had specified num_after=0 (since we didn't check).

This was the cause of the mobile issue
https://github.com/zulip/zulip-mobile/issues/3654.

The solution is to allow passing a special value of anchor='newest',
basically a special string-type value that the server can interpret as
meaning the user precisely just wants the most recent messages.  We
also add an analogous anchor='oldest' or similar to avoid folks
needing to write a somewhat ugly anchor=0 for fetching the very first
messages.

We may want to also replace the use_first_unread_anchor argument to be
a "first_unread" value for the anchor parameter.

While it's not always ideal to make a value have a variable type like
this, in this case it seems like a really clean way to express the
idea of what the user is asking for in the API.

Tim Abbott c0712431df openapi: Add hacky support for oneOf parameter types.
This is required for the upcoming type behavior of the "anchor"
parameter.

This change is the minimal work required to have our OpenAPI code not
fail when checking a union-type value of this form.  We'll likely want
to, in the future, do something nicer, but it'd require more extensive
infrastructure for parsing of OpenAPI data that it's worth with our
current approach (we may want to switch to using a library).

Tim Abbott 91f1825474 test_helpers: Fix POSTRequestMock typing.
The proximal issue here is that in upcoming commits, we're going to
change the type of the `anchor` field in `get_messages_backend` to
support passing either an integer or a string.

Many of our tests using POSTRequestMock currently define a query
object that uses integer values for the integer fields we're going to
pass into it, e.g. {'num_after': 0}.  That is the correct type for
that field in the Zulip API, before HTTP encoding turns it into a
string.  However, because POSTRequestMock didn't use HTTP encoding at
all (which will convert the 0 into a '0'), it ended up passing an
integer to a function that can't possible receive one as an argument.

Ideally, we'd just get rid of POSTRequestMock, since it's a hack, and
just do real HTTP requests instead.

But since it's used in a lot of places making doing so somewhat
impractical, we can get past this issue by just making POSTRequestMock
convert integers to strings.

Rohitt Vashishtha 630c564fc7 bugdown: Rewrite List Preprocessor logic to properly parse fences.
Previously, we didn't track opening and closing fences separately,
with led to bugs like not parsing a list that was immediately after
a quoted fence; we treated each ``` as a new fence.

This commit rewrites the function to maintain a stack of currently
open fences. If any of the parent fences is a code fence, we do not
insert a new line before a list.

We also add some test cases specifically to test this behavior with
complexly nested lists.

Mateusz Mandera 8d987ba5ae auth: Use tokens, with data stored in redis, for log_into_subdomain.
The desktop otp flow (to be added in next commits) will want to generate
one-time tokens for the app that will allow it to obtain an
authenticated session. log_into_subdomain will be the endpoint to pass
the one-time token to. Currently it uses signed data as its input
"tokens", which is not compatible with the otp flow, which requires
simpler (and fixed-length) token. Thus the correct scheme to use is to
store the authenticated data in redis and return a token tied to the
data, which should be passed to the log_into_subdomain endpoint.

In this commit, we replace the "pass signed data around" scheme with the
redis scheme, because there's no point having both.

This allows us to remove an unnecessary import from test_runner.py,
which in combination with DEFAULT_REALM's definition was causing us to
run models code before running migrations inside test-backend.

(That bug, in turn, caused test-backend's check for whether migrations
needs to be run to happen sadly after trying to access a Realm,
trigger a test-backend crash if the Realm model had changed since the
last provision).

Anders Kaseorg ea6934c26d dependencies: Remove WebSockets system for sending messages.
Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013.  We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not.  Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.

While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.

This WebSockets code path had a lot of downsides/complexity,
including:

* The messy hack involving constructing an emulated request object to
  hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
  needs and must be provisioned independently from the rest of the
  server).
* A duplicate check_send_receive_time Nagios test specific to
  WebSockets.
* The requirement for users to have their firewalls/NATs allow
  WebSocket connections, and a setting to disable them for networks
  where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
  been poorly maintained, and periodically throws random JavaScript
  exceptions in our production environments without a deep enough
  traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
  server restart, and especially for large installations like
  zulipchat.com, resulting in extra delay before messages can be sent
  again.

As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients.  We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.

If we later want WebSockets, we’ll likely want to just use Django
Channels.

Mateusz Mandera c011d2c6d3 email_mirror: Migrate missed message addresses from redis to database.
Addresses point 1 of #13533.

MissedMessageEmailAddress objects get tied to the specific that was
missed by the user. A useful benefit of that is that email message sent
to that address will handle topic changes - if the message that was
missed gets its topic changed, the email response will get posted under
the new topic, while in the old model it would get posted under the
old topic, which could potentially be confusing.

Migrating redis data to this new model is a bit tricky, so the migration
code has comments explaining some of the compromises made there, and
test_migrations.py tests handling of the various possible cases that
could arise.

Fixes #13504.

This commit is purely an improvement in error handling.

We used to not do any validation on keys before passing them to

validation would throw an exception.  Unfortunately, the resulting
error messages are super hard to read; the traceback structure doesn't
even show where the call into memcached happened.

In this commit we add validation to all the basic cache_* functions, and
appropriate handling in their callers.

We also add a lot of tests for the new behavior, which has the nice
effect of giving us decent coverage of all these core caching
functions which previously had been primarily tested manually.

In 3892a8afd8, we restructured the
system for managing uploaded files to a much cleaner model where we
just do parsing inside bugdown.

That new model had potentially buggy handling of cases around both
relative URLs and URLS starting with `realm.host`.

We address this by further rewriting the handling of attachments to
avoid regular expressions entirely, instead relying on urllib for
parsing, and having bugdown output `path_id` values, so that there's
no need for any conversions between formats outside bugdowm.

The check_attachment_reference_change function for processing message
updates is significantly simplified in the process.

The new check on the hostname has the side effect of requiring us to
fix some previously weird/buggy test data.

Tim Abbott 299896b6ce notifications: Ignore mobile presence when sending notifications.
Previously, if the user had interacted with the Zulip mobile app in
the last ~140 seconds, it's likely the mobile app had sent presence
data to the Zulip server, which in turns means that the Zulip server
might not send that user mobile push notifications (or email
notifications) about new messages for the next few minutes.

The email notifications behavior is potentially desirable, but the
push notifications behavior is definitely not -- a private message
reply to something you sent 2 minutes ago is definitely something you
want a push notification for.

This commit partially addresses that issue, by ignoring presence data
from the ZulipMobile client when determining whether the user is
currently engaging with a Zulip client (essentially, we're only
considering desktop activity as something that predicts the user is
likely to see a desktop notification or is otherwise "online").

Previously, we would naively set has_attachment just by searching

prevent running do_claim_attachments for messages that obviously
do not have an attachment in them that we previously ran.

For example: attachments in codeblocks or
             attachments that otherwise do not match our link syntax.

The new implementation runs that check on only the urls that
bugdown determines should be rendered. We also refactor some
Attachment tests in test_messages to test this change.

The new method is:

1. Create a list of potential_attachment_urls in Bugdown while rendering.
2. Loop over this list in do_claim_attachments for the actual claiming.
   For saving:
3. If we claimed an attachment, set message.has_attachment to True.
   For updating:
3. If claimed_attachment != message.has_attachment: update has_attachment.

We do not modify the logic for 'unclaiming' attachments when editing.

Nat1405 d5f005fd61 wildcard_mentions_notify: Add per-stream override of global setting.
Adds required API and front-end changes to modify and read the
wildcard_mentions_notify field in the Subscription model.

It includes front-end code to add the setting to the user's "manage
streams" page. This setting will be greyed out when a stream is muted.
The PR also includes back-end code to add the setting the initial state of
a subscription.

New automated tests were added for the API, events system and front-end.
In manual testing, we checked that modifying the setting in the front end
persisted the change in the Subscription model. We noticed the notifications
were not behaving exactly as expected in manual testing; see
https://github.com/zulip/zulip/issues/13073#issuecomment-560263081 .

Tweaked by tabbott to fix real-time synchronization issues.

Mateusz Mandera dda3ff41e1 messages: Optimize get_recent_private_conversations.
Previously, get_recent_private_messages could take 100ms-1s to run,
contributing a substantial portion of the total runtime of `/`.

We fix this by taking advantage of the recent denormalization of
personal_recipient into the UserProfile model, allowing us to avoid
the complex join with Recipient that was previously required.

The change that requires additional commentary is the change to the
main, big SQL query:
1. We eliminate UserMessage table from the query, because the condition
m.recipient_id=%(my_recipient_id)d
implies m is a personal message to the user being processed - so joining
with usermessage to check for user_profile_id and flags&2048 (which
checks the message is private) is redundant.
2. We only need to join the Message table with UserProfile
(on sender_id) and get the sender's personal_recipient_id from their
UserProfile row.

Fixes #13437.
2019-12-09 15:23:10 -08:00
Mateusz Mandera 8acfa17fe6 models: Add recipient foreign key in UserProfile and Stream.
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.

Vishnu KS c8ede33fc3 openapi: Specify securityScheme for the API in root level.
We used to specify the securityScheme for each REST operation seperately.
This is unecessary as the securityScheme can be specified in root level
and would be automatically applied to all operations. This also prevents
us accidentally not specifying the securityScheme for some operations and
was the case for /users/me/subscriptions PATCH endpoint. The root level
securityScheme can be also overriden in the operational level when
necessary.

2019-12-04 09:58:22 -08:00
Mateusz Mandera 7d0444f903 push_notifs: Improve handling of errors when talking to the bouncer.
We use the plumbing introduced in a previous commit, to now raise
PushNotificationBouncerRetryLaterError in send_to_push_bouncer in case
of issues with talking to the bouncer server. That's a better way of
dealing with the errors than the previous approach of returning a
"failed" boolean, which generally wasn't checked in the code anyway and
did nothing.
The PushNotificationBouncerRetryLaterError exception will be nicely
handled by queue processors to retry sending again, and due to being a
JsonableError, it will also communicate the error to API users.
2019-12-04 09:58:22 -08:00
Mateusz Mandera 20b30e1503 push_notifs: Set up plumbing for retrying in case of bouncer error.
We add PushNotificationBouncerRetryLaterError as an exception to signal
an error occurred when trying to communicate with the bouncer and it
should be retried. We use JsonableError as the base class, because this
signal will need to work in two roles:
1. When the push notification was being issued by the queue worker
PushNotificationsWorker, it will signal to the worker to requeue the
event and try again later.
2. The exception will also possibly be raised (this will be added in the
next commit) on codepaths coming from a request to an API endpoint (for
example to add a token, to users/me/apns_device_token). In that case,
it'll be needed to provide a good error to the API user - and basing
this exception on JsonableError will allow that.

This simple change switches us to take advantage of the

This should make it a lot more convenient to find historical private
message conversations, since one can effectively scroll infinitely
into the history.

We'll need to do some profiling of the backend after this is deployed
in production; it's possible we'll need to add some database indexes,
denormalization, or other optimizations to avoid making loading the
Zulip app significantly slower.

Tim Abbott 54e357e154 avatars: Fix gravatar URLs with EMAIL_ADDRESS_VISIBILITY_ADMINS.
Previously, we were using user_profile.email rather than
user_profile.delivery_email in all calculations involving Gravatar
URLs, which meant that all organizations with the new
EMAIL_ADDRESS_VISIBILITY_ADMINS setting enabled had useless gravatars
not based on the `user15@host.domain` type fake email addresses we
generate for the API to refer to users.

The fix is to convert these calculations to use the user's
delivery_email.  Some refactoring is required to ensure the data is
passed through to the parts of the codebase that do the check;
fortunately, our automated tests of schemas are effective in verifying
that the new `sender_delivery_email` field isn't visible to the API.

Fixes #13369.

Tim Abbott 399acea755 outgoing webhooks: Call finalize_payload on payloads.
Apparently, the refactor months ago that introduced finalize_payload
wasn't applied to the outgoing webhook code path, resulting in message
dicts with an unexpected format with no avatar_url and some extra
values that were intended to be internal details not relevant to
external clients.

Because this API is not widely used, we expect there to be little to
no impact of converting this back to matching the `get_messages`
interface, as it once was and has always been intended to be.

The one somewhat tricky detail is that we include both the `content`
and `rendered_content` fields, rather than asking the client to pick
which they want via the `apply_markdown` flag, because there is no
place for the client to configure that setting.

Mateusz Mandera dbe508bb91 models: Migration of Message.pub_date to date_sent, part 2.
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.

Tim Abbott c869a3bf82 upload: Fix browser caching of uploads with local uploads backend.
Apparently, our change in b8a1050fc4 to
stop caching responses on API endpoints accidentally ended up
affecting uploaded files as well.

Fix this by explicitly setting a Cache-Control header in our Sendfile
responses, as well as changing our outer API caching code to only set
the never cache headers if the view function didn't explicitly specify
them itself.

This is not directly related to #13088, as that is a similar issue
with the S3 backend.

Thanks to Gert Burger for the report.

Tim Abbott 7e0ea61b00 upload: Support S3-compatible S3 hosting providers.
Previously, we were hardcoding the domain s3.amazonaws.com.  Given
that we already have an interface for configuring the host in
/etc/zulip/boto.cfg (which in turn, automatically configures boto), we
just need to actually use the value configured in boto for what S3
hostname to use.

We don't have tests for this new use case, in part because they're
likely annoying to write with `moto` and there hasn't been a huge
amount of demand for it.  Since this doesn't regress existing S3
backend support, it seems worth merging.

Tim Abbott b8b0ae362c uploads: Only initialize S3 connection once in __init__.
This should be a mild performance optimization for the S3
authentication backend, since we aren't initializing unnecessary
duplicate connections.

Hemanth V. Alluri 98a33c0fda page_params: Fix list of config_options sent for incoming webhook bots.
This patches an issue in f37535044 where we mistakenly tried to send
the function as part of the page_params. Instead, we should just try
to send the list of configuration options (in their user displayable
form).

Tim Abbott 96726c00ce export: Fix broken URLs in UI with S3 backend.
Apparently, the Zulip notifications (and resulting emails) were
correct, but the download links inside the Zulip UI were incorrectly
not including S3 prefix on the URL, making them not work.

While we're at this, we rewrite the somewhat convoluted previous
system for formatting the data export output.

Tim Abbott 6e5c99328a models: Extract a helper function for whether emails are realm-public.
This is also a useful preparatory refactor for having a user setting

within the organization.

Tim Abbott 767a1b9f0c user_activity: Skip an unnecessary database query for new entries.

Tim Abbott 5c960b3e0f user_activity: Make the queue processor a bit more efficient.
We don't actually need to go to the memcached (falling back to the
database) to fetch either user or client objects on every event.  For
user objects, we actually can just pass through the user ID
transparently; for client objects, we can use an in-process cache,
since the mapping of string to ID never changes.

Anders Kaseorg cf5a00d94b bulk_get_subscriber_user_ids: Sort each user list by ID.
This simple backwards-compatible change saves approximately 12% in the
compressed size of the chat.zulip.org page_params.  We can do much,
much better by changing the format, but this seems like a good
intermediate step.

Anders Kaseorg 780ecb672b CVE-2019-16216: Fix MIME type validation.
* Whitelist a small number of image/ types to be served as
  non-attachments.
* Serve the file using the type that we validated rather than relying
  on an independent guess to match.

This issue can lead to a stored XSS security vulnerability for older
browsers that don't support Content-Security-Policy.

It primarily affects servers using Zulip's local file uploads backend
for servers running Ubuntu 16.04 Xenial or newer; the legacy local
file upload backend for (now EOL) Ubuntu 14.04 Trusty was not affected
and it has limited impact for the S3 upload backend (which uses an
unprivileged S3 bucket domain to serve files).

Thomas Ip 574c35c0b8 markdown: Render ordered lists using <ol> markup.
This brings us in line, and also allows us to style these more like
unordered lists, which is visually more appealing.

On the backend, we now use the default list blockprocessor + sane list
extension of python-markdown to get proper list markup; on the
frontend, we mostly return to upstream's code as they have followed
CommonMark on this issue.

Using <ol> here necessarily removes the behaviour of not renumbering
on lists written like 3, 4, 7; hopefully users will be OK with the
change.

Fixes #12822.

Mateusz Mandera a7ec1a089c errors: Fix infinite recursion during memcached outages.
We have a very useful piece of code, _RateLimitFilter, which is
designed to avoid sending us a billion error emails in the event that
a Zulip production server is down in a way that throws the same
exception a lot. The code uses memcached to ensure we send each
traceback roughly once per Zulip server per 10 minutes (or if
memcached is unavailable, at most 1/process/10 minutes, since we use
memcached to coordinate between processes)

However, if memcached is down, there is a logging.error call internal
to the Django/memcached setup that happens inside the cache.set() call,
and those aren't caught by the `except Exception` block around it.

This ends up resulting in infinite recursion, eventually leading to
Fatal Python error: Cannot recover from stack overflow., since this
handler is configured to run for logging.error in addition to
logging.exception.

We fix this using a thread-local variable to detect whether we are
being called recursively.

This change should prevent some nasty failure modes we've had in the
past where memcached being down resulted in infinite recursion
(resulting in extra resources being consumed by our error
notifications code, and most importantly, the error notifications not
being sent).

Fixes #12595.

Tim Abbott 70c513a640 analytics: Fix logging for errors connecting to push bouncer.
There's no reason for this to be a category of error that emails the
server administrator, since there's a good chance that fixing it will
need to be done in the Zulip codebase, not administrator action.

Mateusz Mandera d70e1bcdb7 settings: Add FAKE_EMAIL_DOMAIN setting.
Fixes #9401.

This adds a FAKE_EMAIL_DOMAIN setting, which should be used if
EXTERNAL_HOST is not a valid domain, and something else is needed to
form bot and dummy user emails (if email visibility is turned off).
It defaults to EXTERNAL_HOST.

get_fake_email_domain() should be used to get this value. It validates
that it's correctly set - that it can be used to form valid emails.

If it's not set correctly, an exception is raised. This is the right
approach, because it's undesirable to have the server seemingly
peacefully operating with that setting misconfigured, as that could
mask some hidden sneaky bugs due to UserProfiles with invalid emails,
which would blow up the moment some code that does validate the emails
is called.

Tim Abbott 62c9ea7cf9 linkifiers: Fix problems with capture groups called "name".
Apparently, due to poor naming of the outer capture group we use to
separate the actual match from the surrounding whitespace (etc.) we
use to determine if the syntax is a possible linkifier start/end, if
you created a linkifier using "name" as the capture group, we'd try to
compile a pattern with two capture groups called "name", which would
500, preventing anyone from accessing the organization.

Tim Abbott 0ed0bb6828 messages: Add email/push notifications for wildcard mentions.
Historically, Zulip's implementation of wildcard mentions never
triggered either email or push notifications, instead being limited to
desktop notifications and the "mentions" counter.

We fix this just by plumbing the "wildcard_mentioned" flag through our
system.

Rohitt Vashishtha abe2dab88c markdown: Upgrade to use InlineProcessor for links.
This commit wraps up the major work that we held back when upgrading
py-markdown 2.6.11 to 3.0.1. Since we were making our custom changes
to the link syntax, at the time we stuck to using the old method of
parsing links. This lays the groundwork for further changes to our
link and image link handling, and brings us on par with upstream.

Also, we now better document the ways in which our link handling is
different from upstream.

Tim Abbott 5e19546c14 messages: Fix unread_msgs accounting of wildcard mentions.
Previously, the unread_msgs data structure accounting (used for both
the web and mobile apps to determine the "Unread mentions" count
displayed in the UI) did not include wildcard mentions at all.

We fix this by adding the logic required to include properly that
data, with tests.  As discussed in #6040, it makes sense to include
muted streams and topics for the purpose of this calculation.

Fixes part of #6040.
