This reverts commit 620b2cd6e.
Contributors setting up a new development environment were getting

The issue appears to be that we're using the `typing` module from the
3.5 stdlib, rather than the `typing=3.6.2` in our requirements files,
and that doesn't understand the `Callable[..., HttpResponse]` that
appears in the definition of `FuncKwargPair`.
Revert for now to get provision working again; at least one person
reports that reverting this sufficed. We'll need to do more testing
before putting this change back in.
The name `create_logger` suggests something much bigger than what this
function actually does -- the logger doesn't any more or less exist
after the function is called than before. Its one real function is to
send logs to a specific file.
So, pull out that logic to an appropriately-named function just for
it. We already use `logging.getLogger` in a number of places to
simply get a logger by name, and the old `create_logger` callsites can
do the same.
From the docs:
> This function does nothing if the root logger already has handlers
> configured for it.
Which we do if we've started up Django and configured settings, and in
particular allowed Django to process `settings.LOGGING`.
So, cut it out -- all it can do is confuse people about how logging
works.
If we ever actually used the `log_format` parameter, this would be
doubly confused, because only the first call would have any effect.
Because calls to `create_logger` generally run after settings are
configured, these would override what we have in `settings.LOGGING` --
which in particular defeated any attempt to set log levels in
`test_settings.py`. Move all of these settings to the same place in
`settings.py`, so they can be overridden in a uniform way.
This is already the loglevel we set on the root logger, so this has no
effect -- except in tests, where `test_settings.py` attempts to set
some of these same loggers to higher loglevels. Because the
`create_logger` call generally runs after we've configured settings,
it clobbers that effect.
The code in `test_settings.py` that tries to suppress logs only works
because it also sets `propagate=False`, which has nothing to do with
loglevels but does cause logs at this logger (and descendants) to be
dropped completely unless we've configured handlers for this logger
(or one of its relevant descendants.)
Adds a markdown preprocessor that finds ordered lists where all items
use the same number and change them to be in normal increasing order,
starting with that number.
Fixes#5159.
Eventually this check for the realm will be done in get_object_from_key
itself. Rewriting this to fit the pattern in get_object_from_key.
No change to behavior.
Commit d4ee3023 and its parent have the history behind this code.
Since d4ee3023^, all new PreregistrationUser objects, except those for
realm creation, have a non-None `realm`. Since d4ee3023, any legacy
PreregistrationUsers, with a `realm` of None despite not being for
realm creation, are treated as expired. Now, we ignore them
completely, and remove any that exist from the database.
The user-visible effect is to change the error message for
registration (or invitation) links created before d4ee3023^ to be
"link does not exist", rather than "link expired".
This change will at most affect users upgrading straight from 1.7 or
earlier to 1.8 (rather than from 1.7.1), but I think that's not much
of a concern (such installations are probably long-running
installations, without many live registration or invitation links).
[greg: tweaked commit message]
We should omit these for mypy. For most class definitions,
mypy doesn't need `Any`, and it provides no real useful info.
For clever monkeypatches, you should provide a more specific
type than `Any`.
The original logic is buggy now that emails can belong to (and be
invited to) multiple realms.
The new logic in the `invites` queue worker also avoids the bug where
when the PreregistrationUser was gone by the time the queue worker got
to the invite (e.g., because it'd been revoked), we threw an exception.
[greg: fix upgrade-compatibility logic; add test; explain
revoked-invite race above]
This code changes frequently enough that errors are bound to creep in. The
main change is that this sends the original invitation email instead of the
reminder email, but I think that's fine.
We'll need the expanded test coverage when we move
check_prereg_key_and_redirect to zerver/views/registration.py to avoid
test failures, and these are also tests we should really have anyway.
Empirically, the retry in `_on_connection_closed` didn't actually work
-- if a reconnect failed, that was it, and the exception handler
didn't get run. A traceback would get logged, but all its frames were
in Tornado or Pika, not our own code; presumably something magic and
async was happening to the exception.
Moreover, though we would make one attempt to reconnect if we had a
connection that got closed, we didn't have any form of retry if the
original attempt at connecting failed in the first place.
Happily, upstream offers a perfectly reasonable bit of API that avoids
both of these problems: the on-open-error callback. So use that.
This method was new in Tornado 4.0. It saves us from having to get
the time ourselves and do the arithmetic -- which not only makes the
code a bit shorter, but also easier to get right. Tornado docs (see
http://www.tornadoweb.org/en/stable/ioloop.html) say we should have
been getting the time from `ioloop.time()` rather than hardcoding
`time.time()`, because the loop could e.g. be running on the
`time.monotonic()` clock.
Adding it afterward is inherently racy, and upstream's API is quite
reasonable for avoiding that -- just like we can pass an on-open
callback up front, we can do the same with the on-close callback.
This is a more thorough version of 4adf2d5c2 from back in 2013-04.
The default value of this parameter is already False upstream.
(It was already False in pika version 0.9.6, which we were
supposedly using when we introduced this in 4baeaaa52; not sure
what the story was there.)
Previously, we weren't doing a proper left join in
user_groups_in_realm_serialized, resulting in empty user groups being
excluded from the query. We want to leave decisions about excluding
empty user groups to the UI layer, so we include these here.
These are the exceptions to the rule that our queues correspond to
queue-processor workers.
Purging `notify_tornado` in particular is a useful workaround right
now for some error spew in the dev environment.
Because we use access_stream_by_id here, and that checks for an active
subscription to interact with a private stream, this didn't work.
The correct fix to add an option to active_stream_by_id to accept an
argument indicating whether we need an active subscription; for this
use case, we definitely do not.
For example, this means that if a user already has an account on one
realm and they try to make an account on another by hitting "Sign in
with Google" (rather than following the little "Register" link to a
"Sign up with Google" button instead), they'll get to make an account
instead of getting an error.
Until very recently, if the user existed on another realm, any attempt
to register with that email address had to fail in the end, so this
logic gave the user a useful error message early. We introduced it in
c23aaa178 "GitHub: Show error on login page for wrong subdomain"
back in 2016-10 for that purpose. No longer! We now support reusing
an email on multiple realms, so we let the user proceed instead.
This function's interface is kind of confusing, but I believe when its
callers use it properly, `invalid_subdomain` should only ever be true
when `user_profile` is None -- in which case the revised
`invalid_subdomain` condition in this commit can never actually fire,
and the `invalid_subdomain` parameter no longer has any effect. (At
least some unit tests call this function improperly in that respect.)
I've kept this commit to a minimal change, but it would be a good
followup to go through the call sites, verify that, eliminate the use
of `invalid_subdomain`, then remove it from the function entirely.
[Modified by greg to (1) keep `USERNAME_FIELD = 'email'`,
(2) silence the corresponding system check, and (3) ban
reusing a system bot's email address, just like we do in
realm creation.]
As we migrate to allow reuse of the same email with multiple realms,
we need to replace the old "no email reuse" validators. Because
stealing the email for a system bot would be problematic, we still ban
doing so.
This commit only affects the realm creation logic, not registering an
account in an existing realm.
Just now this is largely redundant with `test_signup_already_active`;
but very soon when we allow reusing an email across realms, the logic
will diverge.
The one thing this bit of logic is used for is to decide whether
there's an existing user which is a mirror dummy that we should
activate. This change causes us to ignore such an existing user if
it's on some other realm, and go straight into `do_create_user`.
This code appears to exist to cover a few extra lines in
zerver/lib/digest.py. But it's rather brittle, tucked as it is into
the middle of a different test's loop, and with the upcoming
introduction of the `lear` realm in testing, this test code itself
loses coverage.
For now, rather than fix this test code up just delete it; we don't
have 100% coverage on `zerver/lib/digest.py`, while we do on this test
file, so that avoids breaking coverage in CI. As a followup, we
should add back some logic like this but in a more robust way,
probably as its own separate test method.
This test would produce a bunch of log messages with tracebacks,
complaining that `welcome-bot@zulip.com` tried to send cross-realm PMs
and can't. The issue is that the test overrides
`settings.CROSS_REALM_BOT_EMAILS`, and hasn't kept up with additions
to the normal value for that setting. Update it so that welcome-bot
is permitted as usual.
Originally this used signals, namely SIGRTMIN. But in prod, the
signal handler never fired; I debugged fruitlessly for a while, and
suspect uwsgi was foiling it in a mysterious way (which is kind of
the only way uwsgi does anything.)
So, we listen on a socket. Bit more code, and a bit trickier to
invoke, but it works.
This was developed for the investigation of memory-bloating on
chat.zulip.org that led to a331b4f64 "Optimize query_all_subs_by_stream()".
For usage instructions, see docstring.
In two factor authentication every step adds a unique prefix to the fields,
due to this the name of the form fields differs from the HTML fields. If
we do not do this we will have to change the name in the HTML, which
will cause the change in tests.
There's one migration required by this release:
* queue_processors: Stop passing state_handler to handle_message.
state_handler is now a property of bot_handler and thus, does
not need to be passed to bot_handler.handle_message().

This completes the last commit's work to fix CVE-2017-0910, applying
to any invite links already created before the fix was deployed. With
this change, all new-user registrations must match an explicit realm
in the PreregistrationUser row, except when creating a new realm.
[greg: rewrote commit message]
We would allow a user with a valid invitation for one realm to use it
on a different realm instead. On a server with multiple realms, an
authorized user of one realm could use this (by sending invites to
other email addresses they control) to create accounts on other
realms. (CVE-2017-0910)
With this commit, when sending an invitation, we record the inviting
user's realm on the PreregistrationUser row; and when registering a
user, we check that the PregistrationUser realm matches the realm the
user is trying to register on. This resolves CVE-2017-0910 for
newly-sent invitations; the next commit completes the fix.
[greg: rewrote commit message]
This fixes some subtle JavaScript exceptions we've been getting in
zulipchat.com, caused by the system bot realm there not being "zulip"
interacting with get_cross_realm_users.
This should help protect us from future issues with the way that
`bulk_get_users` does caching.
It's likely that we'll want to further restructure `bulk_get_users` to
not have this base_query code path altogether (since it's kinda
buggy), but I'm going to defer that for a time when we have another
user.
The previous implementation had a subtle caching bug: because it was
sharing its cache with the `get_user_profile_by_email` cache, if a
user happened to have an email in that cache, we'd return it, even
though that user didn't match `base_query`.
This causes `get_cross_realm_users` to no longer have a problematic
caching bug.
Hides URL if the message content == image url so that sending gifs or
images feels less cluttered. Uses the url_to_a() function to generate
the expected url string for matching.
Fixes#7324.
Appends "Test: " text to some tests to make changes to the image preview
rendering. In the future, if the message is only a link to an image,
the link will be hidden.
We include ERROR_BOT in this set, even though it's not technically
cross-realm (it just lives in the admin realm).
This code path does not correctly handle emails that correspond to
multiple accounts (because `get_system_bot` does not). Since it's
intended to only be used by system bots, we add an appropriate
assertion to ensure it is only used for system bots.
This was causing problems, because internal_send_message assumes that
there is a unique user (across all realms) with the given email
address (which is sorta required to support cross-realm bot messages
the way it does).
With this change, it now, in practice, only sends cross-realm bot
messages.
We now ignore payloads where payload['push']['changes'] is empty,
because an empty push doesn't really convey any useful information.
I couldn't find a way to replicate the action that would generate
such a payload, so I took one of our existing payloads and editted
out payload['push']['changes'] myself, so this payload is not
authentic.
Previously, this was a ValidationError, but that doesn't really make
sense, since this condition reflects an actual bug in the code.
Because this happened to be our only test coverage the ValidationError
catch on line 84 of registration.py, we add nocoverage there for now.
