Mateusz Mandera f078509105 saml: Extract logic for determining if subdomain is allowed by an attr.
This logic has some trickiness due to the need to handle root subdomain
aliases, so this is worth extracting into a helper for use in other
backends.

Alex Vandiver e5f62d083e tornado: Merge the TORNADO_SERVER and TORNADO_PORTS configs.
Having both of these is confusing; TORNADO_SERVER is used only when
there is one TORNADO_PORT.  Its primary use is actually to be _unset_,
and signal that in-process handling is to be done.

Rename to USING_TORNADO, to parallel the existing USING_RABBITMQ, and
switch the places that used it for its contents to using
TORNADO_PORTS.

Alex Vandiver 2a12fedcf1 tornado: Remove explicit tornado_processes setting; compute it.
We can compute the intended number of processes from the sharding
configuration.  In doing so, also validate that all of the ports are
contiguous.

This removes a discrepancy between `scripts/lib/sharding.py` and other
parts of the codebase about if merely having a `[tornado_sharding]`
section is sufficient to enable sharding.  Having behaviour which
changes merely based on if an empty section exists is surprising.

This does require that a (presumably empty) `9800` configuration line
exist, but making that default explicit is useful.

After this commit, configuring sharding can be done by adding to
`zulip.conf`:

```
[tornado_sharding]
9800 =              # default
9801 = other_realm
```

Followed by running `./scripts/refresh-sharding-and-restart`.

Alex Vandiver f638518722 tornado: Move default production port to 9800.
In development and test, we keep the Tornado port at 9993 and 9983,
respectively; this allows tests to run while a dev instance is
running.

In production, moving to port 9800 consistently removes an odd edge
case, when just one worker is on an entirely different port than if
two workers are used.

Alex Vandiver 536bd3188e middleware: Move locale-setting before domain checking.
Calling `render()` in a middleware before LocaleMiddleware has run
will pick up the most-recently-set locale.  This may be from the
_previous_ request, since the current language is thread-local.  This
results in the "Organization does not exist" page occasionally being
in not-English, depending on the preferences of the request which that
thread just finished serving.

Move HostDomainMiddleware below LocaleMiddleware; none of the earlier
middlewares call `render()`, so are safe.  This will also allow the
"Organization does not exist" page to be localized based on the user's
browser preferences.

Unfortunately, it also means that the default LocaleMiddleware catches
the 404 from the HostDomainMiddlware and helpfully tries to check if
the failure is because the URL lacks a language component (e.g.
`/en/`) by turning it into a 304 to that new URL.  We must subclass
the default LocaleMiddleware to remove this unwanted functionality.

Doing so exposes a two places in tests that relied (directly or
indirectly) upon the redirection: '/confirmation_key'
was redirected to '/en/confirmation_key', since the non-i18n version
did not exist; and requests to `/stats/realm/not_existing_realm/`
incorrectly were expecting a 302, not a 404.

This regression likely came in during f00ff1ef62, since prior to
that, the HostDomainMiddleware ran _after_ the rest of the request had
completed.

This undoes a small part of b8a2e6b5f8; namely, logs to

UnsupportedWebhookEventType, should still be logged to the main error
loggers.  This maintains the property that exceptions generating 500's
are all present in `errors.log`.

Anders Kaseorg 463929f349 urls: Migrate re_path routes to path.
Django treats path("<name>") like re_path(r"(?P<name>[^/]+)") and
path("<path:name>") like re_path(r"(?P<name>.+)").

This is more readable and consistent than the mix of slightly
different regexes we had before, and fixes various bugs:

• The r'apps/(.*)$' regex was missing a start anchor ^, so it
  incorrectly matched all URLs that included apps/ as a substring
  anywhere.
• The r'accounts/login/(google)/$' regex was missing a start anchor ^,
  so it incorrectly matched all URLs that ended with
  accounts/login/google/.
• The type annotation of zerver.views.realm_export.delete_realm_export
  takes export_id as an int, but it was previously passed as a string.
• The type annotation of zerver.views.users.avatar takes medium as a
  bool, but it was previously passed as a string.
• The [0-9A-Za-z]+ pattern for uidb64 was missing the - and _
  characters that can validly be part of a base64url encoded
  string (although I think the id is actually a decimal integer here,
  in which case only 012345ADEIMNOQTUYcgjkwxyz are present in its
  base64url encoding).

Alex Vandiver 9ea9752e0e webhooks: Rename UnexpectedWebhookEventType to UnsupportedWebhookEventType.
Any exception is an "unexpected event", which means talking about

this is about an _unsupported_ event type.

This also switches the path that these exceptions are written to,
accordingly.

Alex Vandiver 3d24571cad sentry: Send user identifiers, but strip PII.
By default, the Django Sentry integration provides the email address
and username of pulled from the auth layer.  This is potentially PII,
and not data that we wish to store.  Enable sending user data at all,
by setting `send_default_pii=True`, but strip the username and
email (which are the same, in Zulip) before sending.  Users will be
identified in Sentry only by their IP address, user ID, realm, and
role.
2020-09-03 17:32:16 -07:00
Alex Vandiver 012113c542 models: Force the translated role into a translated string.
The return type of `ugettext_lazy('...')` (aliased as `_`) is a
promise, which is only forced into a string when it is dealt with in
string context.  This `django.utils.functional.lazy.__proxy__` object
is not entirely transparent, however -- it cannot be serialized by
`orjson`, and `isinstance(x, str) == False`, which can lead to
surprising action-at-a-distance.

In the two places which will serialize the role value (either into
Zulip's own error reporting queue, or Sentry's), force the return
value.  Failure to do this results in errors being dropped
mostly-silently, as they cannot be serialized and enqueued by the
error reporter logger, which has no recourse but to just log a
warning; see previous commit.

When we do this forcing, explicitly override the language to be the
realm default.  Failure to provide this override would translate the
role into the role in the language of the _request_, yielding varying
results.

Via API, users can now access messages which are in web-public

Any malformed narrow which is not allowed in a web-public query
results in a 400 or 401. See test_message_fetch for the allowed
queries.

Alex Vandiver 596cf2580b sentry: Ignore all SuspiciousOperation loggers.
django.security.DisallowedHost is only one of a set of exceptions that
are "SuspiciousOperation" exceptions; all return a 400 to the user
when they bubble up[1]; all of them are uninteresting to Sentry.
While they may, in bulk, show a mis-configuration of some sort of the
application, such a failure should be detected via the increase in
400's, not via these, which are uninteresting individually.

While all of these are subclasses of SuspiciousOperation, we enumerate
them explicitly for a number of reasons:

 - There is no one logger we can ignore that captures all of them.
   Each of the errors uses its own logger, and django does not supply
   a `django.security` logger that all of them feed into.

 - Nor can we catch this by examining the exception object.  The
   SuspiciousOperation exception is raised too early in the stack for
   us to catch the exception by way of middleware and check
   `isinstance`.  But at the Sentry level, in `add_context`, it is no
   longer an exception but a log entry, and as such we have no
   `isinstance` that can be applied; we only know the logger name.

 - Finally, there is the semantic argument that while we have decided
   to ignore this set of security warnings, we _may_ wish to log new
   ones that may be added at some point in the future.  It is better
   to opt into those ignores than to blanket ignore all messages from
   the security logger.

This moves the DisallowedHost `ignore_logger` to be adjacent to its
kin, and not on the middleware that may trigger it.  Consistency is
more important than locality in this case.

Of these, the DisallowedHost logger if left as the only one that is
explicitly ignored in the LOGGING configuration in
`computed_settings.py`; it is by far the most frequent, and the least
likely to be malicious or impactful (unlike, say, RequestDataTooBig).

There are three exceptions in Python3 which are descended from
BaseException, but not Exception: GeneratorExit, KeyboardInterrupt,

For example, SystemExit is raised by `sys.exit`; in that sense, it is
never "uncaught" because we chose to cause it explicitly.

necessity for the override.

Mateusz Mandera 6a50911032 auth: Allow signing in to an existing account with noreply github email.
In particular importing gitter data leads to having accounts with these
noreply github emails. We generally only want users to have emails that
we can actually send messages to, so we'll keep the old behavior of
disallowing sign up with such an email address. However, if an account
of this type already exists, we should allow the user to have access to
it.

Steve Howell c44500175d database: Remove short_name from UserProfile.
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.

Rohitt Vashishtha 912e372c4e markdown: Remove !avatar() and !gravatar() syntax.
This particular commit has been a long time coming. For reference,
!avatar(email) was an undocumented syntax that simply rendered an
inline 50px avatar for a user in a message, essentially allowing
you to create a user pill like:

`!avatar(alice@example.com) Alice: hey!`

---

Reimplementation

If we decide to reimplement this or a similar feature in the future,
we could use something like `<avatar:userid>` syntax which is more
in line with creating links in markdown. Even then, it would not be
a good idea to add this instead of supporting inline images directly.

Since any usecases of such a syntax are in automation, we do not need
to make it userfriendly and something like the following is a better
implementation that doesn't need a custom syntax:

`![avatar for Alice](/avatar/1234?s=50) Alice: hey!`

---

History

We initially added this syntax back in 2012 and it was 'deprecated'
from the get go. Here's what the original commit had to say about
the new syntax:

> We'll use this internally for the commit bot.  We might eventually
> disable it for external users.

We eventually did start using this for our github integrations in 2013
but since then, those integrations have been neglected in favor of
our GitHub webhooks which do not use this syntax.

When we copied `!gravatar` to add the `!avatar` syntax, we also noted
that we want to deprecate the `!gravatar` syntax entirely - in 2013!

Since then, we haven't advertised either of these syntaxes anywhere
in our docs, and the only two places where this syntax remains is
our game bots that could easily do without these, and the git commit
integration that we have deprecated anyway.

We do not have any evidence of someone asking about this syntax on
chat.zulip.org when developing an integration and rightfully so- only
the people who work on Zulip (and specifically, markdown) are likely
to stumble upon it and try it out.

This is also the only peice of code due to which we had to look up
emails -> userid mapping in our backend markdown. By removing this,
we entirely remove the backend markdown's dependency on user emails
to render messages.

Mateusz Mandera d51afcf485 emails: Improve handling of timeouts when sending.
We use the EMAIL_TIMEOUT django setting to timeout after 15s of trying

queue, due to the retry_send_email_failures decorator.

smtlib documentation suggests that socket.timeout can be raised as the
result of timing out, so in attempts I'm getting
smtplib.SMTPServerDisconnected. Either way, seems appropriate to add
socket.timeout to the exception that we catch.

wowol fec77381ee urls: Migrate zproject urls to use modern django patterns.
This migrations use of url() to path() or re_path().  In this commit,
we only migration regular expressions to path where the translation is trivial:
* URLs with no parameters in them
* URLs with only integer parameters in them
* Strings where there regular expression just checked for `/`s
path; strings, which can have variable validation in the URLs that
need by-hand auditing, we leave for future commits that are easier to
review and think about the individual changes.

Modified by tabbott to convert back to `re_path` various URLs with
strings that had been converted to use `path()` with string
validation to simplify review.

Dinesh 04671f40ae auth: Add auth_name attribute for non external auth backends.
This commit adds `name` attribute for the backends that do not
have them.

This is just a kind of prep commit in case if we want to use
`self.logger.xxxx()` in the future which is dependent on the
`name` attribute. But right now these logging calls aren't used
anywhere in those backends.

Dinesh e22ca9483e logging: Log exception name also in auth_complete.

Dinesh d30f11888a logging: Set up a different logger for each backend.
Adds a top-level logger in `settings.LOGGING` `zulip.auth`
with the default handlers `DEFAULT_ZULIP_HANDLERS` and
an extra hanlder that writes to `/var/log/zulip/auth.log`.

Each auth backend uses it's own logger, `self.logger` which
is in form 'zulip.auth.<backend name>'.

This way it's clear which auth backend generated the log
and is easier to look for all authentication logs in one file.

Besides the above mentioned changes, `name` attribute is added to
`ZulipAuthMixin` so that these logging kind of calls wouldn't raise
any issues when logging is tried in a class without `name` attribute.

Also in the tests we use a new way to check if logger calls are made
i.e. we use `assertLogs` to test if something is logged.

Thanks to Mateusz Mandera for the idea of having a seperate logger
for auth backends and suggestion of using `assertLogs`.

Helps to see if users are often trying to login with deactived

This implementation adds a new key `inactive_user_id`

check if a `user_profile` is active. This reduces the effort
of getting `user_id` just before logging.

Mateusz Mandera dd40649e04 queue_processors: Remove the slow_queries queue.
While this functionality to post slow queries to a Zulip stream was
very useful in the early days of Zulip, when there were only a few
hundred accounts, it's long since been useless since (1) the total
request volume on larger Zulip servers run by Zulip developers, and
(2) other server operators don't want real-time notifications of slow
backend queries.  The right structure for this is just a log file.

We get rid of the queue and replace it with a "zulip.slow_queries"
logger, which will still log to /var/log/zulip/slow_queries.log for
ease of access to this information and propagate to the other logging
handlers.  Reducing the amount of queues is good for lowering zulip's
memory footprint and restart performance, since we run at least one
dedicated queue worker process for each one in most configurations.

Dinesh a3329f288c auth: Modify `filter_usable_emails` to only exclude noreply github emails.

just filter `@noreply.github.com` and handle verified/unverified
part in their respective functions because of `@noreply.github.com`
exception being a fiddly special-case detail.
Also renamed `filter_usable_emails` to `get_usable_email_objects`
as a line that gets all associated github emails is removed in
`get_verified_emails` and `get_unverified_emails` and added to
`filter_usable_emails`. The name `filter_usable_emails` suggests

Mateusz Mandera f1ec02b40a auth: Add ExternalAuthResult to manage data in authentication flows.
This new type eliminates a bunch of messy code that previously
involved passing around long lists of mixed positional keyword and

about the state of an external authentication (constructed in
backends.py).

The result is a significantly more readable interface between
zproject/backends.py and zerver/views/auth.py, though likely more
could be done.

This has the side effect of renaming fields for internally passed
structures from name->full_name, next->redirect_to; this results in
most of the test codebase changes.

Modified by tabbott to add comments and collaboratively rewrite the
initialization logic.

Steve Howell e47e1cd648 droplet settings: Fix hostname-related settings.
We recently changed our droplet setup such that their
host names no longer include zulipdev.org.  This caused
a few things to break.

The particular symptom that this commit fixes is that
we were trying to server static assets from
showell:9991 instead of showell.zulipdev.org:9991,
which meant that you couldn't use the app locally.
(The server would start, but the site's pretty unusable
without static assets.)

Now we rely 100% on `dev_settings.py` to set
`EXTERNAL_HOST` for any droplet users who don't set
that var in their own environment.  That allows us to
remove some essentially duplicate code in `run-dev.py`.

We also set `IS_DEV_DROPLET` explicitly, so that other
code doesn't have to make inferences or duplicate
logic to detemine whether we're a droplet or not.

And then in `settings.py` we use `IS_DEV_DROPLET` to
know that we can use a prod-like method of calculating
`STATIC_URL`, instead of hard coding `localhost`.

We may want to iterate on this further--this was
sort of a quick fix to get droplets functional again.
It's possible we can re-configure droplets to have
folks get reasonable `EXTERNAL_HOST` settings in their
bash profiles, or something like that, although that
may have its own tradeoffs.

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.

Dinesh 5888d7c0f5 auth: Change how config error URLs are configured.
URLs for config errors were configured seperately for each error
which is better handled by having error name as argument in URL.
A new view `config_error_view` is added containing context for
each error that returns `config_error` page with the relevant
context.
Also fixed tests and some views in `auth.py` to be consistent with
changes.

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.

Mateusz Mandera bf0f1274fa saml: Make the bad idp param KeyError log message more verbose.
Original idea was that KeyError was only going to happen there in case

misconfiguration, so it's worth logging more info as it may help in
debugging the configuration.

Tim Abbott 229090a3a5 middleware: Avoid running APPEND_SLASH logic in Tornado.
Profiling suggests this saves about 600us in the runtime of every GET
/events request attempting to resolve URLs to determine whether we
need to do the APPEND_SLASH behavior.

It's possible that we end up doing the same URL resolution work later
and we're just moving around some runtime, but I think even if we do,
Django probably doesn't do any fancy caching that would mean doing
this query twice doesn't just do twice the work.

In any case, we probably want to extend this behavior to our whole API
because the APPEND_SLASH redirect behavior is essentially a bug there.
That is a more involved refactor, however.

Tim Abbott 4fbcbeeea7 settings: Disable django.request logging at WARNING log level.
The comment explains this issue, but effectively, the upgrade to
Django 2.x means that Django's built-in django.request logger was
writing to our errors logs WARNING-level data for every 404 and 400
error.  We don't consider user errors to be a problem worth
highlighting in that log file.

rht 41e3db81be dependencies: Upgrade to Django 2.2.10.
Django 2.2.x is the next LTS release after Django 1.11.x; I expect
we'll be on it for a while, as Django 3.x won't have an LTS release
series out for a while.

Because of upstream API changes in Django, this commit includes
several changes beyond requirements and:

* urls: django.urls.resolvers.RegexURLPattern has been replaced by
  django.urls.resolvers.URLPattern; affects OpenAPI code and related
  features which re-parse Django's internals.
  https://code.djangoproject.com/ticket/28593
* test_runner: Change number to suffix. Django changed the name in this
  ticket: https://code.djangoproject.com/ticket/28578
* Delete now-unnecessary SameSite cookie code (it's now the default).
* forms: urlsafe_base64_encode returns string in Django 2.2.
  https://docs.djangoproject.com/en/2.2/ref/utils/#django.utils.http.urlsafe_base64_encode
* upload: Django's File.size property replaces _get_size().
  https://docs.djangoproject.com/en/2.2/_modules/django/core/files/base/
* process_queue: Migrate to new autoreload API.
* test_messages: Add an extra query caused by .refresh_from_db() losing
  the .select_related() on the Realm object.
* session: Sync SessionHostDomainMiddleware with Django 2.2.

There's a lot more we can do to take advantage of the new release;
this is tracked in #11341.

Many changes by Tim Abbott, Umair Waheed, and Mateusz Mandera squashed
are squashed into this commit.

Fixes #10835.
2020-02-13 16:27:26 -08:00
Tim Abbott 1ea2f188ce tornado: Rewrite Django integration to duplicate less code.
Since essentially the first use of Tornado in Zulip, we've been
maintaining our Tornado+Django system, AsyncDjangoHandler, with
several hundred lines of Django code copied into it.

The goal for that code was simple: We wanted a way to use our Django
middleware (for code sharing reasons) inside a Tornado process (since
we wanted to use Tornado for our async events system).

As part of the Django 2.2.x upgrade, I looked at upgrading this
implementation to be based off modern Django, and it's definitely
possible to do that:
* Continue forking load_middleware to save response middleware.
* Continue manually running the Django response middleware.
* Continue working out a hack involving copying all of _get_response
  to change a couple lines allowing us our Tornado code to not
  actually return the Django HttpResponse so we can long-poll.  The
  previous hack of returning None stopped being viable with the Django 2.2
  MiddlewareMixin.__call__ implementation.

But I decided to take this opportunity to look at trying to avoid
copying material Django code, and there is a way to do it:

* Replace RespondAsynchronously with a response.asynchronous attribute
  on the HttpResponse; this allows Django to run its normal plumbing
  happily in a way that should be stable over time, and then we
  proceed to discard the response inside the Tornado `get()` method to
  implement long-polling.  (Better yet might be raising an
  exception?).  This lets us eliminate maintaining a patched copy of
  _get_response.

* Removing the @asynchronous decorator, which didn't add anything now
  that we only have one API endpoint backend (with two frontend call
  points) that could call into this.  Combined with the last bullet,
  this lets us remove a significant hack from our
  never_cache_responses function.

* Calling the normal Django `get_response` method from zulip_finish
  after creating a duplicate request to process, rather than writing
  totally custom code to do that.  This lets us eliminate maintaining
  a patched copy of Django's load_middleware.

* Adding detailed comments explaining how this is supposed to work,
  what problems we encounter, and how we solve various problems, which
  is critical to being able to modify this code in the future.

A key advantage of these changes is that the exact same code should
work on Django 1.11, Django 2.2, and Django 3.x, because we're no
longer copying large blocks of core Django code and thus should be
much less vulnerable to refactors.

There may be a modest performance downside, in that we now run both
request and response middleware twice when longpolling (once for the
request we discard).  We may be able to avoid the expensive part of
it, Zulip's own request/response middleware, with a bit of additional
custom code to save work for requests where we're planning to discard
the response.  Profiling will be important to understanding what's
worth doing here.

Mateusz Mandera 5f94ea3d54 auth: Rate limit username+password authenticate() calls.
This applies rate limiting (through a decorator) of authenticate()
functions in the Email and LDAP backends - because those are the ones
where we check user's password.
The limiting is based on the username that the authentication is
attempted for - more than X attempts in Y minutes to a username is not
permitted.

If the limit is exceeded, RateLimited exception will be raised - this
can be either handled in a custom way by the code that calls
authenticate(), or it will be handled by RateLimitMiddleware and return
a json_error as the response.
