Tim Abbott 8bdbcbc371 lint: Fix unnecessarily translated test file strings.
Our linter for translation strings shouldn't check test files, since
then we'll end up translating non-user-facing strings.

So we fix that, and actually add the opposite lint rule.

adnrs96 ae31c6cc0d avatar: Move avatar data from email based to user id based.
This commit introduces a migration for moving avatars from email based
to user id based storage.

This is in responce to change in behaviour of user_avatar_path to
return path comprising of realm id and a hash based on user id. Also
we fix test_helpers accordingly.

Fixes #3776.

Ayush Jain 455c1919fc Add customizable invite-new-user text.
This makes life a lot easier for people inviting users to a new Zulip
organization, since they can give some form of context now.

Modified by tabbott to clean up CSS, backend code flow, and improve
the formatting of the emails.

Fixes: #1409.

Tommy Ip c7e33c6c9f optimization: Use Python to test management commands.
The original test was written in shell script which launches a new
django instance for every tests. By doing it in Python, we avoid
the overhead and reduce the test time to <1 second.

Fixes #3620.

Umair Khan 7743f74180 Do not append to INSTRMENTED_DATA directly.
Use append_instrumentation_data to append data to the INSTRUMENTED_DATA.
This gives us a layer of abstraction when we need to add instrumentation
data from other modules e.g. while running tests in parallel mode.
2017-02-10 16:01:43 -08:00
Umair Khan 78768a2ba9 Add process_instrumentation_data function.
This function can be used to perform processing on instrumentation data.
For example, this can be used to send the instrumentation data gathered
in the test suite running in the child process to the parent process for
aggregation.
2017-02-10 16:01:43 -08:00
Eklavya Sharma 415ce9c312 zerver/lib/test_helpers.py: Wrap function in lambda.
Wrap `list.append` in a lambda before assigning it to
event_queue.process_notification to prevent errors when
event_queue.process_notification is used with keyword arguments.

This also removes an error message by mypy 0.4.7.

Add test about avatar image was uploaded properly or not in
`tests.BotTest.test_add_bot_with_user_avatar` and
`tests.BotTest.test_patch_bot_avatar`.

Add `get_test_image_file()` and `avatar_disk_path()` in
`zerver.lib.test_helpers` and deduplicate some codes.

Reid Barton ecfa397567 Fix several type annotations for mypy 0.4.6 compatibility.
A few functions had arguments removed without having their type
annotations updated accordingly. As a result mypy version 0.4.6
thinks that the first type in the annotation is supposed to be
the type of `self`, a new mypy feature which we are not intending
to use here.

Tim Abbott 5e0d2c4e1b tests: Exclude markdown files from shallow template testing.
The markdown files under templates/zerver/help/ are technically not
templates in the standard sense, and thus should not be being
checked with this code path.

(We probably do want to add a test to make sure they all render fine,
but that can be its own project.)

Tim Abbott 169d404579 tornado: Move zerver.lib.handlers into zerver.tornado.handlers.

Steve Howell 6ed1dc9341 Create api docs from url coverage data from tests.

Steve Howell 5f5e6b6d83 tests: Enforce 100% URL coverage.
We now instrument URL coverage whenever you run the back end tests,
and if you run the full suite and fail to test all endpoints, we
exit with a non-zero exit code and report failures to you.

If you are running just a subset of the test suite, you'll still
be able to see var/url_coverage.txt, which has some useful info.

With some tweaks to the output from tabbott.

Fixes #1441.

Rishi Gupta c1713c9659 Prevent code from using email domain to determine realm when subdomains.
Also removes the intermediate step of going through Realm.domain in the
non-subdomains case. Part of a larger project to remove Realm.domain
entirely.

2016-11-10 19:29:43 -08:00
Rishi Gupta e3646f28bd test_helpers.py: Fix default args for submit_reg_form_for_user.
Previously realm_name and realm_subdomain defalted to None, which when
posted to /accounts/register, are submitted as u'None'. "None" is an invalid
Realm.subdomain, since subdomains can't have capital letters.
2016-11-04 22:01:53 -07:00
Steve Howell c405b67138 tests: Ignore SAVEPOINT queries in queries_captured().
We use the queries_captured() context manager in our tests
to capture queries that happen during certain actions.  Usually
we use the list of queries to validate that we're not doing
too many database calls.

For most tests the database calls are fairly deterministic,
but SAVEPOINT-related things seem to be more random, and the
number of savepoints is usually not relevant to what the test
is trying to prevent, which is more serious problems like
O(N) database fetches.

Rishi Gupta 777fcaa6a0 Add new organization type field to Realm objects.
Adds a new field org_type to Realm.  Defaults for restricted_to_domain
and invite_required are now controlled by org_type at time of realm
creation (see zerver.lib.actions.do_create_realm), rather than at the
database level.  Note that the backend defaults are all
org_type=corporate, since that matches the current assumptions in the
codebase, whereas the frontend default is org_type=community, since if
a user isn't sure they probably want community.

Since we will likely in the future enable/disable various
administrative features based on whether an organization is corporate
or community, we discuss those issues in the realm creation form.
Before we actually implement any such features, we'll want to make
sure users understand what type of organization they are a member of.

Choice of org_type (via radio button) has been added to the realm
creation flow and the realm creation management command, and the
open-realm option removed.

The database defaults have not been changed, which allows our testing code
to work unchanged.

[includes some HTML/CSS work by Brock Whittaker to make it look nice]

hackerkid ea39fb2556 Add option for hosting each realm on its own subdomain.
This adds support for running a Zulip production server with each
realm on its own unique subdomain, e.g. https://realm_name.example.com.

This patch includes a ton of important features:
* Configuring the Zulip sesion middleware to issue cookier correctly
  for the subdomains case.
* Throwing an error if the user tries to visit an invalid subdomain.
* Runs a portion of the Casper tests with REALMS_HAVE_SUBDOMAINS
  enabled to test the subdomain signup process.
* Updating our integrations documentation to refer to the current subdomain.
* Enforces that users can only login to the subdomain of their realm
  (but does not restrict the API; that will be tightened in a future commit).

Note that toggling settings.REALMS_HAVE_SUBDOMAINS on a live server is
not supported without manual intervention (the main problem will be
adding "subdomain" values for all the existing realms).

Supriya 4959e8d10a tests: Extract and use assert_max_length test helper.

2. no-shallow

    fail if it finds a template which is shallow tested.

Tomasz Kolek c4254497b2 Add WebhookTestCase abstract class for writing webhook tests.
This cuts a ton of code duplication and semi-duplication between the
webhook tests, and thus should make it a lot easier to write new ones.

Tim Abbott 71a06d58de Convert uses of Realm.objects.get() to get_realm().
get_realm is better in two key ways:
* It uses memcached to fetch the data from the cache and thus is faster.
* It does a case-insensitive query and thus is more safe.

Zev Benjamin 814aed7cbe Send an event when a stream is created, is deleted, becomes occupied, or becomes vacant
A stream is vacant when it has no subscribers and occupied when it has at least
one subscriber.

We have a slightly odd model where stream creation is conflated with
subscription creation.  Streams are created by attempting to subscribe to a
stream that doesn't exist.  We also hide streams with no subscribers from users
to make it seem like they've gone away.  However, we can't actually remove those
streams because we want to preserve history.

This commit moves us towards a separation of these two concepts.  By sending
events for stream creation, occupation, vacancy, and deletion, we allow clients
to directly observe the global state of streams rather than indirectly observing
subscription information.  A more complete solution would involve adding a view
for explicitly creating streams without subscribing to them.

This commit does not handle the intricacies of invite-only streams.  We
currently simply do not send these events for invite-only streams.
