orientor 9170931da3 openapi: Add test for validating examples.
Zulip's openapi specification in zulip.yaml has various examples
for various schemas. Validate the example with their respective
schemas to ensure that all the examples are schematically correct.

Part of #14100.

Tim Abbott 35139ac559 api: Remove email field from realm_user and realm_bot events.
The `email` field for identifying the user being modified in these
events was not used by either the webapp or other official Zulip
clients.  Instead, it was legacy data from before we switched years
ago to sending user_id fields as the correct way to uniquely identify
a user.

clarammdantas 7e9024a39c popovers.js: Add version to user avatar request.
When a user changes its avatar image, the user's avatar in popovers
wasn't being correctly updated, because of browser caching of the
avatar image.  We added a version on the request to get the image in
the same format we use elsewhere, so the browser knows when to use the
cached image or to make a new request to the server.

Edited by Tim to preserve/fix sort orders in some tests, and update
zulip_feature_level.

Steve Howell 9137726e38 bots: Remove `owner` (email) from bot-related payloads.
We remove the `owner` field from `page_params/realm_bots`
and bot-related events.

In the recent commit 155f6da8ba
we added `owner_id`, which we now use everywhere we need
bot owners for.

We also bump the `API_FEATURE_LEVEL` to 5 here.  We
had already documented this in the prior commit to
add `owner_id`.

Note that we don't have to worry about mobile/ZT clients
here--we only deal with bot data in the webapp.
2020-05-12 09:48:37 -07:00
Steve Howell 155f6da8ba bots: Add owner_id to bot-related payloads.
For the below payloads we want `owner_id` instead
of `owner`, which we should deprecate.  (The
`owner` field is actually an email, which is
not a stable key.)

    page_params.realm_bots

    realm_bot/add

    realm_bot/update

IMPORTANT NOTE: Some of the data served in
these payloads is cached with the key
`bot_dicts_in_realm_cache_key`.

For page_params, we get the new field
via `get_owned_bot_dicts`.

For realm_bot/add, we modified
`created_bot_event`.

For realm_bot/update, we modified
`do_change_bot_owner`.

On the JS side, we no longer
look up the bot's owner directly in
`server_events_dispatch` when we get
a realm_bot/update event. Instead, we
delegate that job to `bot_data.js`.
I modified the tests accordingly.

Rohitt Vashishtha 26238426cd message-edit: Process user groups for mentioned user ids.
When editing a message where we mention a usergroup, we would remove
the 'mentioned' flag from messages, resulting in the message being
hidden from your mentions in the UI. This was reported by Greg Price in
https://chat.zulip.org/#narrow/stream/9-issues/topic/missing.20mention.

We add the same code that we use in do_send_messages to calculate the
updated mentions_user_ids. We add some tests alongside other user group
mention tests in test_bugdown.

Chris Heald c80e913c7a webhooks: Add a webhook capable of parsing Slack payloads.
This adds a webhook that can be used to interpret standard Slack
payloads. Since there are a ton of existing Slack integrations out
there, having a webhook which can accept standard Slack payloads can
significantly ease transition pains. Obviously this can't do everything
that Slack payloads can (particularly WRT their widgets/interactions),
but we can ingest text and parse out multi-block payloads into a message
relatively reasonably.

Pragati Agrawal bd9b74436c org settings: Enable message_retention_days in org settings UI.
Since production testing of `message_retention_days` is finished, we can
enable this feature in the organization settings page. We already had this
setting in frontend but it was bit rotten and not rendered in templates.

Here we replaced our past text-input based setting with a
dropdown-with-text-input setting approach which is more consistent with our
existing UI.

Along with frontend changes, we also incorporated a backend change to
handle making retention period forever. This change introduces a new
convertor `to_positive_or_allowed_int` which only allows positive integers
and an allowed value for settings like `message_retention_days` which can
be a positive integer or has the value `Realm.RETAIN_MESSAGE_FOREVER` when
we change the setting to retain message forever.

This change made `to_not_negative_int_or_none` redundant so removed it as
well.

Pragati Agrawal 12504075ee org settings: Rename plan_includes_wide_organization_logo to more generic.

of it too.

Steve Howell ebb16e7a68 error logging: Simplify deployment data.
We no longer have intermediate constants of
`git_described` and `zulip_version_const`.

Instead, we make a `deployment_data` dictionary
that is grep-friendly, and we just let
`deployment_repr` do simple formatting
without translating string constants.

This is pretty easy to test:

    - set DEBUG_ERROR_REPORTING = True
    - modify some code to throw an exception
    - see error output in #errors
    - use "/emails" with text-only option to view
      errors

Steve Howell 710e3144e7 error logging: Remove `zulip_version_file` code.
This code was bitrotted--we no longer have a file
called `version`.

The info that was probably reported when that feature
was originally written probably lives now
in `zulip-git-version`, although I didn't research
all the history here.  Here is the relevant
excerpt from `version.py`:

    zulip_git_version_file = os.path.join(
        os.path.dirname(os.path.abspath(__file__)),
        'zulip-git-version')

    if os.path.exists(zulip_git_version_file):
        with open(zulip_git_version_file) as f:
            version = f.read().strip()
            if version:
                ZULIP_VERSION = version

The file gets written as follows:

    $ cat tools/cache-zulip-git-version
    #!/usr/bin/env bash
    set -e

    cd "$(dirname "$0")/.."
    git describe --tags --match='[0-9]*' > zulip-git-version || true

Here is what that might look like:

    2.2-dev-2102-gf256ea39eb

Here is an excerpt from one of our recent error reports,
which demonstrates that the code I eliminated here was not
functioning (the third field is missing):

    Deployed code:
    - git: 2.2-dev-2028-g99ce96d49b-dirty
    - ZULIP_VERSION: 2.2-dev-2028-g99ce96d49b

This fixes the main problem reported on #7868.  I think
we may just want to close the issue, since the other
`nocoverage` stuff seems harmless to me.

Rohitt Vashishtha 7d3a31cd8b bugdown: Support hanging_lists preprocessor for indented lists.
Previously, hanging_lists preprocessor didn't consider anything
indented at 4 or above spaces to be a list. This meant that when
we had a list like:

1. 1
  2. 2
    3. 3
  2. 2a
1. 1a

We would insert a newline between 3. 3 and 2. 2a. This resulted
in the block processor breaeking down 1 list into 2 blocks, which
messed up the nesting and indentation for the second block.

Wyatt Hoodes 82e7ad8e25 data exports: Handle pending and failed exports.
Prior to this change, there were reports of 500s in
production due to `export.extra_data` being a
Nonetype.  This was reproducible using the s3
backend in development when a row was created in
the `RealmAuditLog` table, but the export failed in
the `DeferredWorker`.  This left an entry lying
about that was never updated with an `extra_data`
field.

To fix this, we catch any exceptions in the
`DeferredWorker`, and then update `extra_data` to
encode the failure.  We also fix the fact that we
never updated the export UI table with pending exports.

These changes also negated the use for the somewhat
hacky `clear_success_banner` logic.

Aman Agrawal 5fa1dbf5b3 test_fixtures: Add DB function to write database digest.
This will give help up write new digest only if the db rebuild
succeeds. We were relying on the caller to
be successful in building db, this was hacky and unreliable.

We write new db digest once the caller succeeds, this ensures
that we write new digest after every successful attempt.

This fixes the anomality we were facing that Databases were rebuild
on the 2nd provision attempt with no changes to files or migrations.
This was happening because we didn't write a new digest for db
after the first provision (The case of DB didn't exist).

During the 1st provision, we check the template_status() of
Database both Dev and Test, but database_exists() of Databases
obviously returned false, and we rebuild the database,
but forgot to write_new_digest and hence the anomaly in the
second provision explained above.

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
arguments, instead using a consistent data object for communicating
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.

Tim Abbott 03fecba917 alert_words: Fix cache flushing behavior and add tests.
The post_init cache-flushing behavior in the original alert words

We use post_save rather than post_init hooks precisely because they
ensure that we flush the cache after we know the database has been
updated and any future reads from the database will have the latest
state.

Tim Abbott 8e5b0351b3 alert_words: Fix case-sensitivity of alert words.
Previously, alert words were case-insensitive in practice, by which I
mean the Markdown logic had always been case-insensitive; but the data
model was not, so you could create "duplicate" alert words with the
same words in different cases.  We fix this inconsistency by making
the database model case-insensitive.

I'd prefer to be using the Postgres `citext` extension to have
postgres take care of case-insensitive logic for us, but that requires
installing a postgres extension as root on the postgres server, which
is a pain and perhaps not worth the effort to arrange given that we
can achieve our goals with transaction when adding alert words.

We take advantage of the migrate_alert_words migration we're already
doing for all users to effect this transition.

Abhishek-Balaji 052368bd3e alert_words: Move alert_words from UserProfile to separate model.
Previously, alert words were a JSON list of strings stored in a
TextField on user_profile.  That hacky model reflected the fact that
they were an early prototype feature.

This commit migrates from that to a separate table, 'AlertWord'.  The
new AlertWord has user_profile, word, id and realm(denormalization so
we can provide a nice index for fetching all the alert words in a
realm).

This transition requires moving the logic for flushing the Alert Words
caches to their own independent feature.

Note that this commit should not be cherry-picked without the
following commit, which fixes case-sensitivity issues with Alert Words.

Rohitt Vashishtha 087b54aa45 markdown: Keep only 'text' for a no-op pygments rendering.
Previously, we added support for 'none', 'plain' and 'noop' and a
function `lang = remap_language(lang)`. This also had the potential
to encourage adding more remappings- something that we deliberatly
want to keep to a minimum.

For context, Anders K doesn't want us to keep any remapping (only
keeping 'text' which is the default no-op lexer that pygments has)
and Tim wants to keep 'plain' and 'text'. We should only document
and advertise 'text'.

rebtung f7fbe3419f api: Improve consistency of reactions API.
Previously, the message and event APIs represented the user differently
for the same reaction data. To make this more consistent, I added a
user_id field to the reaction dict for both messages and events. I
updated the front end to use the user_id field rather than the user
dict. Lastly, I updated front end and back end tests that used user
info.

I primarily tested this by running my local Zulip build and
adding/removing reactions from messages.

Fixes #12049.

Steve Howell 02252c255a db tools: Use common scheme for digests.
We have two different digest schemes to make
sure we keep the database up to date.  There
is the migration digest, which is NOT in the
scope of this commit, and which already
used the mechanism we use for other tools.

Here we are talking about the digest for
important files like `populate_db.py`.

Now our scheme is more consistent with how we
check file changes for other tools (as
well as the aformentioned migration files).

And we only write one hash file, instead of
seven.

And we only write the file when things have
actually changed.

And we are explicit about side effects.

Finally, we include a couple new bot settings
in the digest:

    INTERNAL_BOTS
    DISABLED_REALM_INTERNAL_BOTS

NOTE: This will require a one-time transition,
where we rebuild both databases (dev/test).
It takes a little over two minutes for me,
so it's not super painful.

I bump the provision version here, even
though you don't technically need it (since
the relevant tools are actually using the
digest files to determine if they need to
rebuild the database).  I figure it's just
good to explicitly make this commit trigger
a provision, and the user will then see
the one-time migration of the hash files
with a little bit less of a surprise.

And I do a major bump, not a minor bump,
because when we go in the reverse direction,
the old code will have to rebuild the
database due to the legacy hash files not
being around, so, again, I just prefer it
to be explicit.

Steve Howell 239474124e test-backend: Remove generate_fixtures option.
We remove the `generate_fixtures` option here mostly
for simplicity, but in particular to facilitate
an upcoming commit to simplify the job of
`generate-fixtures` (and remove its `--force` option).

The command line option here for `test-backend`
was really calling `generate_fixtures --force`,
which we're about to rename `tools/rebuild-test-database`.

The `test-backend` tools is already smart about catching
up on migrations, so we generally don't need to tell it
to repair the database.

And if the database does get corrupt, you can just do
it directly with `tools/rebuild-test-database`.

This eliminates the `use_force` flag in
`update_test_databases_if_required`, which was easy
to confuse with `rebuild_test_database`.

The other caller wasn't using `use_force`.

Somewhat confusingly, we have two types of different

necessitate a complete rebuild of the database.

Anyway, these are just more specific names.

Hashir Sarwar e3b90a5ec8 api: Add a monotonic integer "feature level" for non-webapp clients.
The purpose is to provide a way for (non-webapp) clients,
like the mobile and terminal apps, to tell whether the
server it's talking to is new enough to support a given
API feature -- in particular a way that

* is finer-grained than release numbers, so that for
features developed after e.g. 2.1.0 we can use them
immediately on servers deployed from master (like
chat.zulip.org and zulipchat.com) without waiting the
months until a 2.2 release;

* is reliable, unlike e.g. looking at the number of
commits since a release;

* doesn't lead to a growing bag of named feature flags
which the server has to go on sending forever.

Tweaked by tabbott to extend the documentation.

Closes #14618.

Steve Howell 51f74a7fd8 provision: Manage digests more rigorously.
We now have two functions related to digests
for processes:

    is_digest_obsolete
    write_digest_file

In most cases we now **wait** to write the
digest file until after we've successfully
run a process with its new inputs.

In one place, for database migrations, we
continue to write the digest optimistically.
We'll want to fix this, but it requires a
little more code cleanup.

Here is the typical sequence of events:

    NEVER RUN -
        is_digest_obsolete returns True
        quickly (we don't compute a hash)

        write_digest_file does a write (duh)

    AFTER NO CHANGES -
        is_digest_obsolete returns False
        after reading one file for old
        hash and multiple files to compute
        hash

        most callers skip write_digest_file

        (no files are changed)

    AFTER SOME CHANGES -
        is_digest_obsolete returns False
        after doing full checks

        most callers call write_digest_file
        *after* running a process

Steve Howell ca49f38619 provision: Extract helpers for paths to hash.
I make these all functions for consistency,
and in particular I want to continue to avoid
`glob.glob` calls until we are actually
computing hashes.

This is mostly a prep to allow us to do
hashing in two separate places:

    - check hashes
    - update hashes

We would only update hashes **after** running
processes anew.

For `provision_inner` I considered using a
class to put the three path-related helpers
into a mini namespace, but it felt too heavy.

It wouldn't be completely implausible here
to extract something like a JSON config
file that has a list of globs for each
process that we do path-hashing for, but I
want to clean up other stuff first.

I remove `is_force` from `file_or_package_hash_updated`

If `is_force` is `True`, we just now run the thing
we want to force-run without having to call
`file_or_package_hash_updated` to expensively
and riskily return `True`.

Another nice outcome of this change is that if
`file_or_package_hash_updated` returns `True`,
you can know that the file or package has
indeed been updated.

For the case of `build_pygments_data` we also
skip an `os.path.exists` check when `is_force`
is `True`.

We will short-circuit more logic in the next
few commits, as well as cleaning up some of
the long/wrapper lines in the `if` statements.

Also, the tool does not support webhooks with basic auth, and only supports

The Redis-based rate limiting approach takes a lot of time talking to

negative impact on the performance of `get_events()` since this is our
single highest-traffic endpoint.

This commit introduces an in-process rate limiting alternate for
`/json/events` endpoint. The implementation uses Leaky Bucket
algorithm and Python dictionaries instead of Redis. This drops the
rate limiting time for `get_events()` from about 3000us to less than
100us (on my system).

Fixes #13913.

Rohitt Vashishtha f9caf522f0 markdown: Allow setting a default language for code blocks.
This adds a new realm setting: default_code_block_language.

This PR also adds a new widget to specify a language, which
behaves somewhat differently from other widgets of the same
kind; instead of exposing methods to the whole module, we
just create a single IIFE that handles all the interactions
with the DOM for the widget.

We also move the code for remapping languages to format_code
function since we want to preserve the original language to
decide if we override it using default_code_clock_language.

Fixes #14404.

Abhinav 41fc7b2ae1 webhooks/semaphore: Add support for Semaphore 2.0 notifications.
Semaphore has currently has two different versions of their product -
Classic and 2.0. This commit adds support for Semaphore 2.0, along side
Semaphore Classic, using the same webhook. This would let the integration
work seamlessly for users who have already configured a Zulip integration in
their Semaphore 2.0 projects.

Semaphore 2.0 currently only supports GitHub and their payloads do not
contain URLs for common entities like commits, pull requests and tags. We
construct URLs for them using templates, but also try to support other
services by providing notifications without URLs.

Closes #14171

Mateusz Mandera 46a02e70b0 rate_limiter: Fix inconsistency in an edge case in redis limiter.
If we had a rule like "max 3 requests in 2 seconds", there was an
inconsistency between is_ratelimited() and get_api_calls_left().
If you had:
request #1 at time 0
request #2 and #3 at some times < 2

Next request, if exactly at time 2, would not get ratelimited, but if
get_api_calls_left was called, it would return 0. This was due to
inconsistency on the boundary - the check in is_ratelimited was
exclusive, while get_api_calls_left uses zcount, which is inclusive.

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,

The distinction between ValueError and TypeError
is not useful in these functions:

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.

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.

arpit551 8f7733cb20 emails: Added placeholders strings in FormAddress.
We've had a bug for a while that if any ScheduledEmail objects get
created with the wrong email sender address, even after the sysadmin
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
send_future_email function, so that ScheduledEmail objects end up
setting the final `from_address` value when mail is actually sent
using the setting in effect at that time.

for hydrating PM/huddle recipients.

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.

Emilio López d3c841d587 email_mirror: also check for Envelope-To
After subscribing a stream email address to a Mailman email list
and receiving a message from it (using the polling configuration
with an Exim + Dovecot mailserver), the following error message
is emitted by Zulip:

    Logger zerver.lib.email_mirror, from module zerver.lib.email_mirror line 77:
    Error generated by Anonymous user (not logged in) on zulip deployment

    Sender: "Foo Bar" <foo@example.com>
    To: No recipient found
    Missing recipient in mirror email

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.

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 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.

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.

the optimized version only ~0.05-0.06.

Likely fixes #13874; we can re-open if after production testing we
feel more work is warranted.

Steve Howell fcc5ae5247 invites: Fix regression w/email vs. delivery_email.
In 220c2a5ff3 I
introduced a query to find invites by delivery_email
but was still using email as the key.

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.

Steve Howell 1b16693526 tests: Limit email-based logins.
We now have this API...

If you really just need to log in
and not do anything with the actual
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):

    self.assert_login_failure(email)

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.

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.)

In theory, a nicer version of this would be able to work directly off

Tim Abbott 9230213bde settings: Add EMAIL_ADDRESS_VISIBILITY_NOBODY.
This extends our email address visibility settings to deny access to

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.

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 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 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

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 57f1aa722c refactor: Rename validate_email_for_realm.
Now called:

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.

Steve Howell 49b8218463 perf: Extract get_subscribed_stream_ids_for_user.
This new method prevents us from getting fat
objects from the database.

Instead, now we just get ids from the database
to build our subqueries.

Note that we could also technically eliminate
the `set(...)` wrappers in this code to have
Django make a subquery and save a round trip.
I am postponing that for another commit (since
it's still somewhat coupled to some other
complexity in `do_get_streams` that I am trying
to cut through, plus it's not the main point
of this commit.)

BEFORE:

Steve Howell 504ec9d489 typing: Remove recipient-related complexity.
For historical reasons we were creating Recipient
objects at some point in the typing-notifications
codepath.  Now we just work with UserProfiles.
This removes some queries, as indicated by
the change to `len(queries)` in a couple of the
tests.

The one subtle thing that changes here is huddles.
If user 10 sends a typing notification that they
are talking to users 20 and 30, there might not
actually be a huddle for users 10/20/30, but
we were actually creating huddles on the fly!
There is no need to create huddles just for
typing notifications, since we don't even
share huddle ids with our clients.  The clients
just infer the huddles.

Some of the code that gets killed off here as
somewhat "collateral damage" is some
defensive code related to formerly supporting streams
in typing indicators.  The support for streams
was killed off almost as soon as we released
the feature, and the codepath is pretty clearly
user-centric at this point.

Steve Howell bed6d5a789 typing: Inline check_typing_notification.
I actually like this pattern:

    def check_send_typing_notification(...):
        typing_notification = check_typing_notification(...)
        do_send_typing_notification(...)

It can help divide responsibilities nicely and make it easy
to write detailed unit tests against each of the two helpers.

Unfortunately, the good things didn't really happen here, and
instead we got the worst aspects of the pattern:

    - The responsibilities for validation leaked into
      the second function.

    - Both functions were doing sane things individually
      that became not-so-sane in the big picture (namely,
      we ended up making Recipient objects for no reason,
      but if you read each of the helpers, it was just one
      step that seemed reasonable).

    - Passing around dictionaries for results can be annoying.

Also, the pattern made a lot more sense when the validation
for typing was a lot more complicated.  My prior commit makes
it so that we only ever deal with a list of user_ids.

Anyway, now I'm inlining it. :)

Subsequent commits will clean up the more substantive issue
here, which is that we are building Recipients for no reason.

Steve Howell 995353fb28 message validation: Clean up extract_private_recipients.
This is mostly refactoring, but we also prevent a new

Cleanup includes:

    - Use early-exit for email case.
    - Rename helpers to get_validate_*.
    - Avoid clumsy rebuilding of lists in helpers.
    - Avoid the confusing `recipient` name (which
      can be confused with the model by the same
      name).
    - Just delegate duplicate-id/email-removal to
      the helpers.

The cleaner structure allows us to elminate a couple
mypy workarounds.

Tim Abbott 27edc18330 test_classes: Use realistic web and mobile User-Agent strings.
This fixes a confusing aspect of how our automated tests worked
previously, where we'd almost all HTTP requests in the unlikely
configuration with no User-Agent string specified.

We need to adjust query counts in a few tests that now are a bit
cheaper because they now can take advantage of a Client object created
in server_initialization.py in `process_client`.

Tim Abbott 27b267026e test_classes: Rename set_http_host to set_http_headers.
This supports the goal of setting other headers like User-Agent in the
future.

Tim Abbott d80175d29e server_initialization: Create Client objects for mobile/desktop.
This replaces the "API" client, which isn't used by any real clients,
with the "ZulipMobile" and "ZulipElectron" client strings, which are.

Mateusz Mandera c78d0712f7 tests: For ldap tests, give each ldap user a unique password.
To avoid some hidden bugs in tests caused by every ldap user having the
same password, we give each user a different password, generated based
on their uids (to avoid some ugly hard-coding in a bunch of places).

With recipient being now a Stream field, there's no more use for
this helper function.

Mateusz Mandera 920d22524b import: Use re_map_foreign_keys on the realm column of UserPresence.
We forgot to make this adjustment in the recent denormalization of realm
into UserPresence. It's needed for imports to work correctly.

Anders Kaseorg b2ec8e157b has_request_variables: Remove query_params dict.
‘req_var in request.GET’ was previously believed to be slow from
profiling results.  However, the real explanation for those profiling
results is that WSGIRequest.GET is a lazy cached property, so there’s
no reason to avoid it if we’re accessing request.GET anyway.

Mateusz Mandera cbdfef28a8 retention: Update to account for the zulipinternal realm.
In https://github.com/zulip/zulip/pull/12823 some changes to the realms
structure have been made, so now both in production and development
cross-realm bots live in the realm with string_id "zulipinternal".
There was a TODO in retention code to eliminate a conditional in a query
that became redundant with this change, and also the zulipinternal realm
should be omitted from the archiving process in archive_messages().
