Investigation into #12876, a mysterious bug where users were seeing
messages reappear as unread, determined that the root cause was
missing headers to disable client-side caching for Zulip's REST API
endpoints.
This manifested, in particular, for `GET /messages`, which is
essentially the only API GET endpoint used by the webapp at all. When
using the `Ctrl+Shift+T` feature of browsers to restore a recently
closed tab (and potentially other code paths), the browser would
return from its disk cache a cached copy of the GET /messages results.
Because we include message flags on messages fetched from the server,
this in particular meant that those tabs would get a stale version of
the unread flag for the batches of the most recent ~1200 messages that
Zulip fetches upon opening a new browser tab.
The issue took same care to reproduce as well, in large part because
the arguments to those initial GET /messages requests will vary as one
reads messages (because the `pointer` moves forward) and then enters
the "All messages" view; the disk cache is only used for GET requests
with the exact same URL parameters.
We will probably still want to merge the events error-handling changes
we had previously proposed for this, but the conclusion of this being
a straightforward case of missing cache-control headers is much more
satisfying than the "badly behaving Chrome" theory discussed in the
issue thread.
Fixes#12876.
Django’s default FileSystemFinder disallows STATICFILES_DIRS from
containing STATIC_ROOT (by raising an ImproperlyConfigured exception),
because STATIC_ROOT is supposed to be the result of collecting all the
static files in the project, not one of the potentially many sources
of static files.

In the rare case that Zulip receives an email with only an HTML
format, we originally (code dating to 2013) shelled out to
html2markdown/python-html2text in order to convert the HTML into
markdown.
We long since added html2text as a reasonably managed Python
dependency of Zulip; we should just use it here.
This change serves to declutter webhook-errors.log, which is
filled with too many UnexpectedWebhookEventType exceptions.
Keeping UnexpectedWebhookEventType in zerver/lib/webhooks/common.py
led to a cyclic import when we tried to import the exception in
zerver/decorators.py, so this commit also moves this exception to
another appropriate module. Note that our webhooks still import
this exception via zerver/lib/webhooks/common.py.
Changed the requirements for UserProfile in order to allow use of
the formataddr function in send_mail.py.
Converted send_email to use formataddr in conjunction with the commit
that strengthened requirements for full_name, such that they can now be
used in the to field of emails.
Fixes#4676.
This changes the requirements for UserProfile to disallow some
additional characters, with the overall goal of being able to use
formataddr in send_mail.py.
We don't need to be particularly careful in the database migration,
because user full_names are not required to be unique.
We were seeing errors when pubishing typical events in the form of
`Dict[str, Any]` as the expected type to be a `Union`. So we instead
change the only non-dictionary call, to pass a dict instead of `str`.
Per the import line:
`from unittest import loader, runner # type: ignore # Mypy cannot pick
these up.`
Because `TextTestResult` inherits from `runner.TextTestResult`, mypy
doesn't see `self` as having an attribute `stream`, so we ignore these
instead of cluttering with `casts` or `isinstances`.
The code generating pub_dates for messages would fail to distribute them
across days if tot_messages was too large.
We refactor this code as a separate function (for clarity and to unit
test for the bug we're fixing), and change the structure and naming to a
form that more clearly describes what's happening. We also shift away
from the approach of all the float-to-int conversions as this is in
general tricky and bug prone - django's timedelta() handles floats as
arguments, so we take advantage of that.
Apparently, a subtle mismatch between the filename/URL formats for our
upload codebases meant that importing Slack avatars into systems using
S3_UPLOAD_BACKEND would end up with the avatars having the wrong URLs.
This replaces the two custom Google authentication backends originally
written in 2012 with using the shared python-social-auth codebase that
we already use for the GitHub authentication backend. These are:
* GoogleMobileOauth2Backend, the ancient code path for mobile
authentication last used by the EOL original Zulip Android app.
* The `finish_google_oauth2` code path in zerver/views/auth.py, which
was the webapp (and modern mobile app) Google authentication code
path.
This change doesn't fix any known bugs; its main benefit is that we
get to remove hundreds of lines of security-sensitive semi-duplicated
code, replacing it with a widely trusted, high quality third-party
library.
During the time between when we refactored the GitHub authentication
backend to use SocialAuthBase and now (when we're about to migrate
GoogleAuthBackend to use that code path as well), we accidentally
added some GitHub-specific authentication backend tests to the common
test class.
Fix this by moving them to the GitHub-specific subclass.
This is a prep commit for adding validation of the request variable
types since then we would need to actually analyze the code of the
actual function itself and we would need a variable storing the
function itself.
In commit 7c71e98, we added a special exception for the
/users/me/subscriptions endpoint in the automatic validation test.
By adding some extra documentation, we now remove this extra code,
as well as the endpoint from the list of pending endpoints.
In the validation test, we now use a different message for when there
is an endpoint in pending_endpoints with some documentation already.
This change is a bit hackish, but it's okay since we'll be removing it
once we've resolved all pending endpoints (which is bound to happen).
The previous iteration did not properly handle languages with a
different word order than English.
Discovered via warning output in `manage.py makemessages`.
When we add Plus, the first sentence should change to "Available on Zulip
Standard and Plus".
I copied the styling of .tip out of expediency, but it's also possible that
long term we'll want only 1 tip-like box styling.
The hover styling is a bit random, but I tried to copy other hover styles I
found in settings.scss.
Note that this renames .upgrade_realm_plan_type_suggestion to .upgrade-tip.
If a url doesn't have a scheme, browsers would treat it as a relative
url and open something like: https://chat.zulip.org/google.com instead.
This PR fixes the issue on the backend; the frontend implementation
remains out of sync and the user sending the message wouldn't see
any linkification for urls without a scheme.
Fixes#12791.
The test_docs change is because Django runs test cases with DEBUG =

There’s no reason to monkey-patch something that we were already
subclassing.
Removing the PRODUCTION conditional causes us to generate
staticfiles.json in the right place to begin with so we don’t need to
move it later. It also allows Django to find staticfiles.json if
running the dev server with PIPELINE_ENABLED.

This fixes a user-visible bug, where users signing up for realms with
restricted email visibility get reminder emails 1 week later, whether or not
they created an account.
Making sender name go in-line with message body only if
the html starts with <p> tag since it won't look good

If message starts with p tag we can safely assume that

The decorator running at import time was causing directory
creation in the project's root.
One could imagine linting for this, but it seems unlikely that similar
code will be added in the future; the problem one would be trying to
solved is already addressed by default in the framework now.
It was discovered that errors such as:
`OSError: [Errno 16] Device or resource busy`
potentially arise when running in serial mode, or with
explicit test cases passed to `test-backend`.
In the unlikely event that someone edited the properties of a system
bot and then saved the result, we were still caching the old version
indefinitely in the get_system_bot cache.
This led to a confusing case where a newly installed Zulip server
didn't have is_api_super_user properly set on its EMAIL_GATEWAY_BOT in
memcached.

Previously we sent "" for stream_name where we should have sent None, which
made this function harder to understand. The "" value was never used.
This also reorders the arguments to be match the order of the arguments in
the two callers.
This commit adds a new setting to the user's notification settings that
will change the behaviour of the unread count in the title bar and
desktop application.
When enabled, the title bar will show the count of unread private messages
and mentions. When disabled, the title bar will act as before, showing
the total number of unread messages.
Fixes#1736.
The approach taken here is basically use user IDs in operator that
support it when sending the request for fetching the messages
(see comments in code for more details).
Modified by punchagan to:
* Replace URLs with titles only if the inline url embed previews are turned on
* Add a test for youtube titles replacing URLs
The titles for the videos are fetched asynchronously after the message has been
sent via the code that fetches metadata for open graph previews. So, the URLs
are replaced with titles only if the inline embed url previews feature is
enabled.
Ideally, YouTube previews should be shown only if inline url previews are
enabled, but this feature is in beta, while YouTube previews are pretty stable.
Once this feature is out of beta, YouTube previews should be shown only if the
url previews feature is turned on.
YouTube preview image is calculated as soon as the message is sent, while the
title needs to be fetched using a network request. This means that the URL is
replaced only after the data has been fetched from the request, and happens a
couple of seconds after the message has been rendered.
Closes#7549
Messages with links embedded in blockquotes turn out to be replies to
messages with links, more often than not. Showing previews for links in
replies seems like clutter, and it seems reasonable to turn off previews for
such links.
We create a path structure in the from:
`/var/<uuid>/test-backend/run_1234567/worker_N/`
A settings attribute, `TEST_WORKER_DIR`, was created as a worker's
directory for a given `test-backend` run's file storage. The
appropirate path is created in `setup_test_environment`, while each
workers subdirectory is created within `init_worker`.
This allows a test class to write to `settings.TEST_WORKER_DIR`,
populating the appropirate directory of a given worker. Also
providing the long-term approach to clean up filesystem access
in the backend unit tests.
We implicitly assume settings.NOTIFICATION_BOT is not None just a few lines
above, in
sender = get_system_bot(settings.NOTIFICATION_BOT)
notifications.append(
internal_prep_private_message(
realm=user_profile.realm,
sender=sender,
...
This will make it easier to have access to the stream creator.
The indirection also isn't really adding anything, especially given that the
announce message is inlined just above.
Modified by punchagan to:
* Add a separate markdown test for de-duplicating inline previews
* Check for number of unique URLs to see if per limit message is crossed
* Use a set for processed URLs instead of a list
Fixes#8379.
Extract some logical segments of test_openapi_arguments into
individual (helper) functions. E.g. extraction of the regex
to OpenAPI URL format conversion and testing.
The previous code for the validator test was fairly messy due to
checking for both formats of the openapi url, one with
<variable_name> and the other with {variable_name}. To eliminate
this, we have standardized the format and restricted it to
{variable_name} as per the official format at:
https://swagger.io/docs/specification/describing-parameters.
These updates are added as a direct result of the new strategy related
to the the following refactorings:
* Having `do_export_realm` return the value of the tarball path.
See 6e187e974a4e6282d3616312bdfa19d0d2a949d1.
* Moving the upload logic for s3 and local tarball storage out of
`export_realm_wrapper` and into `upload.py`.
See f1041e1fb6cb60f2c53b294695245e4c86a4d40b.
Add new custom profile field type, External account.
External account field links user's social media
profile with account. e.g. GitHub, Twitter, etc.

Rename URL type custom profile field in populate db to avoid confusion
with the "GitHub profile" custom external account profile field we'll
be adding shortly.
We can simply archive cross-realm personal messages according to the
retention policy of the recipient's realm. It requires adding another
message-archiving query for this case however.
What remains is to figure out how to treat cross-realm huddle messages.
This reverts commit 8f15884c7d. Using the
WITH ( ) ... DELETE method leads to a small performance drop, while
probably not offering many positives, so it seems appropriate to go to
the simpler case of just letting things get cleaned up by CASCADE.
The way the code changed in this commit was written caused Django to
fetch stream.realm from the database for every stream, leading to
redundant, identical queries. Each stream's realm is already known, so
we use that information.
In addition to the test which checks to to see if each endpoint in
code (urls.py) is documented in the openapi documentation (and with
the right arugments). We now also have a test to see if every
endpoint in the openapi documentation is a legitimate endpoint
also existing in code.
We do this by piggy-backing on the work done be the former test and
using set operations. This method avoid the need for an extra loop
and it uses set operations for additional speed and ease of reading.
The main things targeted by the refactor are the usage of comments and
moving the top-level variables to the scope of the class.
The movement of variables was to facilitate allowing us to perform
a reverse mapping test from OpenAPI URLs -> Code defined URLs.
By importing a few view modules in the validation test itself we
can remove a few endpoints which were marked as buggy. What was
happening was that the view functions weren't imported and hence
the arguments map was not filled. Thus the test complained that
there was documentation for request parameters that seemed to be
missing in the code. Also, for the events register endpoint, we
have renamed one of the documented request parameters from
"stream" to "topic" (the API itself was not modified though).
We add a new "documentation_pending" attribute to req variables
so that any arguments not currently documented but should be
documented can be properly accounted for.
DELETing from archive tables and ALTERing ArchivedMessage needs to be
split into separate transactions.
zerver_archivedattachment_messages needs to be cleared out before
zerver_archivedattachment.
The conditional block containing the tarball upload logic for both S3
and local uploads was deconstructed and moved to the more appropriate
location within `zerver/lib/upload.py`.
This change is preliminary refactoring in order to improve the test
mocking strategy related to `test_realm_export.py`.
What this allows is the ability to simply mock a return value from
`do_export_realm`. We can then use that value as a dummy url to
ensure a file has been served and can be retrieved.
Use UserProfiles instead of emails to fetch recipient objects for
narrowing; this is cleaner as it avoids unnecessary parsing and
unparsing. We just map ids/emails operand to user profiles and then
use common code from there.
Fixes#12601.
This reverts commit f476ec7fac (#10312)
