Sahil Batra 2c4e076fef message_edit: Use move_messages_within_stream_limit_seconds setting.
We now use the newly added move_messages_within_stream_limit_seconds
setting to check for how long the user can edit the topic replacing
the previously used 3-day limit. As it was previously, there is no
time limit for admins and moderators.

Sahil Batra 5b1f6a696e message: Refactor code for parsing message time limit settings.
This commit renames parse_message_content_edit_or_delete_limit
to parse_message_time_limit_setting and also renames
MESSAGE_CONTENT_EDIT_OR_DELETE_LIMIT_SPECIAL_VALUES_MAP to
MESSAGE_TIME_LIMIT_SETTING_SPECIAL_VALUES_MAP.

We do this change since this function and object will also be
used for message move limit and it makes sense to have a more
generic name.

Sahil Batra 1a656d2e23 realm: Deduplicate code for parsing message edit and delete limit settings.
This commit extracts a function to parse message time limit type settings
and to set it if the new setting value is None.

This function is currently used for message_content_edit_limit_seconds and
message_content_delete_limit_seconds settings and will be used for
message_move_limit_seconds setting to be added in further commits.

Alex Vandiver e3c976fed9 missed_messages: Include messages from topic which differ by case.
In Zulip, message topics are case-insensitive but case-preserving.
The `get_context_for_message` function erroneously did a
case-sensitive search, and thus only messages whose topic matched
exactly were pulled in as context.

Make the missed-message pipeline aware that message topics are not
case-sensitive.  This means that, when collapsing adjacent messages,
we merge messages with topic headers which are "different"; create a
separate explicit "grouping" to know which to collapse.

Alex Vandiver 23894fc9a3 uploads: Set Content-Type and -Disposition from Django for local files.
Similar to the previous commit, Django was responsible for setting the
Content-Disposition based on the filename, whereas the Content-Type
was set by nginx based on the filename.  This difference is not
exploitable, as even if they somehow disagreed with Django's expected
Content-Type, nginx will only ever respond with Content-Types found in
`uploads.types` -- none of which are unsafe for user-supplied content.

However, for consistency, have Django provide both Content-Type and
Content-Disposition headers.
2023-02-07 17:12:02 +00:00
Alex Vandiver 2f6c5a883e CVE-2023-22735: Provide the Content-Disposition header from S3.
The Content-Type of user-provided uploads was provided by the browser
at initial upload time, and stored in S3; however, 04cf68b45e
switched to determining the Content-Disposition merely from the
filename.  This makes uploads vulnerable to a stored XSS, wherein a
file uploaded with a content-type of `text/html` and an extension of
`.png` would be served to browsers as `Content-Disposition: inline`,
which is unsafe.

The `Content-Security-Policy` headers in the previous commit mitigate
this, but only for browsers which support them.

Revert parts of 04cf68b45e, specifically by allowing S3 to provide
the Content-Disposition header, and using the
`ResponseContentDisposition` argument when necessary to override it to
`attachment`.  Because we expect S3 responses to vary based on this
argument, we include it in the cache key; since the query parameter
has dashes in it, we can't use use the helper `$arg_` variables, and
must parse it from the query parameters manually.

Adding the disposition may decrease the cache hit rate somewhat, but
downloads are infrequent enough that it is unlikely to have a
noticeable effect.  We take care to not adjust the cache key for
requests which do not specify the disposition.

Alex Vandiver d41a00b83b uploads: Extra-escape internal S3 paths.
In nginx, `location` blocks operate on the _decoded_ URI[^1]:

> The matching is performed against a normalized URI, after decoding
> the text encoded in the “%XX” form

This means that if a user-uploaded file contains characters that are
not URI-safe, the browser encodes them in UTF-8 and then URI-encodes
them -- and nginx decodes them and reassembles the original character
before running the `location ~ ^/...` match.  This means that the `$2`
_is not URI-encoded_ and _may contain non-ASCII characters.

When `proxy_pass` is passed a value containing one or more variables,
it does no encoding on that expanded value, assuming that the bytes
are exactly as they should be passed to the upstream.  This means that
directly calling `proxy_pass https://$1/$2` would result in sending
high-bit characters to the S3 upstream, which would rightly balk.

However, a longstanding bug in nginx's `set` directive[^2] means that
the following line:

```nginx
set $download_url https://$1/$2;
```

...results in nginx accidentally URI-encoding $1 and $2 when they are
inserted, resulting in a `$download_url` which is suitable to pass to
`proxy_pass`.  This bug is only present with numeric capture
variables, not named captures; this is particularly relevant because
numeric captures are easily overridden by additional regexes
elsewhere, as subsequent commits will add.

Fixing this is complicated; nginx does not supply any way to escape
values[^3], besides a third-party module[^4] which is an undue
complication to begin using.  The only variable which nginx exposes
which is _not_ un-escaped already is `$request_uri`, which contains
the very original URL sent by the browser -- and thus can't respect
any work done in Django to generate the `X-Accel-Redirect` (e.g., for
`/user_uploads/temporary/` URLs).  We also cannot pass these URLs to
nginx via query-parameters, since `$arg_foo` values are not
URI-decoded by nginx, there is no function to do so[^3], and the
values must be URI-encoded because they themselves are URLs with query
parameters.

Extra-URI-encode the path that we pass to the `X-Accel-Redirect`
location, for S3 redirects.  We rely on the `location` block
un-escaping that layer, leaving `$s3_hostname` and `$s3_path` as they
were intended in Django.

This works around the nginx bug, with no behaviour change.

David Rosa 2b8dfbfe1f help: Improve relative settings links for documentation on bots.
Fixes the documentation generated from the Markdown macros
{settings_tab|your-bots} and {settings_tab|bot-list-admin} to
match the text labels in the Zulip UI and improves the text of
relative links to explicitly say if we are referring to the Bots

This commit moves the Markdown formatting code to a new function that
receives tuples from `link_mapping` as input. This is a preliminary
step to offer more flexibility than the current approach.

Prakhar Pratyush 9997131df3 message_edit: Fix resolve topic notifications.
When 'resolve|unresolve' and 'move stream' actions occurs in
the same api call, 'This topic was marked as resolved|unresolved'
notification is not sent.

Both 'topic moved' and 'topic resolved' notification should be generated.

This commit updates the logic of when and where to send
'topic resolve|unresolve' notification. Unlike previous logic, notification
may be sent even in the case 'new_stream' is not None.

In general, 'topic resolved|unresolved' notification is sent to
'stream_being_edited'. In this particular case ('new_stream' is not None),
notification is sent to the 'new_stream' after check.

Test case is included.

Alessandro Toppi ff89590558 auth: Add JWT-based user API key fetch.
This adds a new endpoint /jwt/fetch_api_key that accepts a JWT and can
be used to fetch API keys for a certain user. The target realm is
inferred from the request and the user email is part of the JWT.

A JSON containing an user API key, delivery email and (optionally)
raw user profile data is returned in response.
The profile data in the response is optional and can be retrieved by
setting the POST param "include_profile" to "true" (default=false).

Mateusz Mandera 6c638a1057 auth: Extract token-check logic of remote_user_jwt.
This will be useful for re-use for implementation of an endpoint for
obtaining the API by submitting a JWT in the next commits.

It's not a pure refactor, as it requires some tweaks to remote_user_jwt
behavior:
1. The expected format of the request is changed a bit. It used to
   expect "user" and "realm" keys, from which the intended email was
   just generated by joining with @. Now it just expects "email"
   straight-up. The prior design was a bt strange to begin with, so this
   might be an improvement actually.
2. In the case of the codepath of new user signup, this will no longer
   pre-populate the Full Name in the registration form with the value
   from the "user" key. This should be a very minor lost of
   functionality, because the "user" value was not going to be a proper
   Full Name anyway. This functionality can be restored in a future
   commit if desired.

This is an API change, but this endpoint is nearly unused as far as
we're aware.

`is_email_notifiable`.

One query reduced for both `test_create_user_with_multiple_streams`
and `test_register`.
Reason: When welcome bot sends message after user creation
`do_send_messages` calls `get_active_presence_idle_user_ids`,
`user_ids` in `get_active_presence_idle_user_ids` remains empty if
`disable_external_notifications` is true because `is_notifiable` returns
false.
`get_active_presence_idle_user_ids` calls `filter_presence_idle_user_ids`
and since the `user_ids` is empty, the query inside the function doesn't
get executed.

MissedMessageHookTest updated.

Alex Vandiver 994806c505 migrations: Fix ownership, and re-attach, mis-owned email attachments.
608c787c52 fixed a bug where messages sent by the email gateway "as"
a user failed to properly attribute ownership of their attachments,
leaving the attachments orphaned and thus with nobody with permissions
to view them.

These orphaned attachments only remain longer than a few weeks if the
`delete_unclaimed_attachments` script has not been run reliably.
Since there is currently no shipped cron job for this, that is most
likely all deployments.

Add a migration to find such orphaned attachments, and re-attach them
to their original message.  While theoretically the attachments
could have been later referenced in other messages -- which would be
very difficult to find and determine if they had access to the
attachment -- we only fix the original message.

In order to make this somewhat performant, we assume that the Message
rows associated with an Attachment made by the email gateway happened
within 5 minutes, since they must have been made during one HTTP
request.

This is complicated by the message potentially having been deleted; in
this case, the Attachment is moved into ArchivedAttachment, so it can
relate to the ArchivedMessage.  The many-to-many
`zerver_archivedattachment_messages` relationship table cannot use its
own `id` sequence for the value, since the `id` is re-used when the
row is inserted into the `zerver_attachment_messages` table -- we
instead consume a value from the `id` sequence of the
`zerver_attachment_messages` table.

Alex Vandiver 608c787c52 email_mirror: Create attachments as the message sender.
When the email mirror gateway is sending messages "as" a user (as
triggered by having access to the missed-message email address),
attachments were still created as the Email Gateway bot.  Since the
sender (the end-user) was not the owner of those attachments (the
gateway bot), nor were they referenced yet anywhere, this resulted in
the attachments being "orphaned" and not allowed to be accessed by
anyone -- despite the attachment links being embedded in the message.
This was accompanied by the error:

```
WARN [] User 12345 tried to share upload 123/3LkSA4OcoG6OpAknS2I0SFAQ/example.jpf in message 123456, but lacks permission
INFO [zerver.lib.email_mirror] Successfully processed email from user 12345 to example-stream
```

We solve this by creating attachment objects as the users the message
will be sent from.

Lauryn Menard c2bcfb52aa api-tests: Reduce error output for `/register` openapi validation.
For descriptive endpoints, such as `/register`, that might raise
Schema Validation errors via `validate_against_openapi_schema`,
omits the OpenAPI schema definition in the error output.

Also omits the error instance definition in the error output
when it is a jsonschema object with over 100 properties. This
means that the test instance for objects, like user settings,
will be printed in the error output, but the test instance for
the entire endpoint will not be printed to the console.

The omitted output can be thousands of lines long making it
difficult to find the initial console output that actually helps
the contributor with debugging.

debugging and understanding these errors that is linked to
in the error console output.

Alex Vandiver 04cf68b45e uploads: Serve S3 uploads directly from nginx.
When file uploads are stored in S3, this means that Zulip serves as a
302 to S3.  Because browsers do not cache redirects, this means that
no image contents can be cached -- and upon every page load or reload,
every recently-posted image must be re-fetched.  This incurs extra
load on the Zulip server, as well as potentially excessive bandwidth
usage from S3, and on the client's connection.

Switch to fetching the content from S3 in nginx, and serving the
content from nginx.  These have `Cache-control: private, immutable`
headers set on the response, allowing browsers to cache them locally.

Because nginx fetching from S3 can be slow, and requests for uploads
will generally be bunched around when a message containing them are
first posted, we instruct nginx to cache the contents locally.  This
is safe because uploaded file contents are immutable; access control
is still mediated by Django.  The nginx cache key is the URL without
query parameters, as those parameters include a time-limited signed
authentication parameter which lets nginx fetch the non-public file.

This adds a number of nginx-level configuration parameters to control
the caching which nginx performs, including the amount of in-memory
index for he cache, the maximum storage of the cache on disk, and how
long data is retained in the cache.  The currently-chosen figures are
reasonable for small to medium deployments.

The most notable effect of this change is in allowing browsers to
cache uploaded image content; however, while there will be many fewer
requests, it also has an improvement on request latency.  The
following tests were done with a non-AWS client in SFO, a server and
S3 storage in us-east-1, and with 100 requests after 10 requests of
warm-up (to fill the nginx cache).  The mean and standard deviation
are shown.

|                   | Redirect to S3      | Caching proxy, hot  | Caching proxy, cold |
| ----------------- | ------------------- | ------------------- | ------------------- |
| Time in Django    | 263.0 ms ±  28.3 ms | 258.0 ms ±  12.3 ms | 258.0 ms ±  12.3 ms |
| Small file (842b) | 586.1 ms ±  21.1 ms | 266.1 ms ±  67.4 ms | 288.6 ms ±  17.7 ms |
| Large file (660k) | 959.6 ms ± 137.9 ms | 609.5 ms ±  13.0 ms | 648.1 ms ±  43.2 ms |

The hot-cache performance is faster for both large and small files,
since it saves the client the time having to make a second request to
a separate host.  This performance improvement remains at least 100ms
even if the client is on the same coast as the server.

Cold nginx caches are only slightly slower than hot caches, because
VPC access to S3 endpoints is extremely fast (assuming it is in the
same region as the host), and nginx can pool connections to S3 and
reuse them.

However, all of the 648ms taken to serve a cold-cache large file is
occupied in nginx, as opposed to the only 263ms which was spent in
nginx when using redirects to S3.  This means that to overall spend
less time responding to uploaded-file requests in nginx, clients will
need to find files in their local cache, and skip making an
uploaded-file request, at least 60% of the time.  Modeling shows a
reduction in the number of client requests by about 70% - 80%.

The `Content-Disposition` header logic can now also be entirely shared
with the local-file codepath, as can the `url_only` path used by
mobile clients.  While we could provide the direct-to-S3 temporary
signed URL to mobile clients, we choose to provide the
served-from-Zulip signed URL, to better control caching headers on it,
and greater consistency.  In doing so, we adjust the salt used for the
URL; since these URLs are only valid for 60s, the effect of this salt
change is minimal.

Alex Vandiver ed6d62a9e7 avatars: Serve /user_avatars/ through Django, which offloads to nginx.
Moving `/user_avatars/` to being served partially through Django
removes the need for the `no_serve_uploads` nginx reconfiguring when
switching between S3 and local backends.  This is important because a
subsequent commit will move S3 attachments to being served through
nginx, which would make `no_serve_uploads` entirely nonsensical of a
name.

Serve the files through Django, with an offload for the actual image
response to an internal nginx route.  In development, serve the files
directly in Django.

We do _not_ mark the contents as immutable for caching purposes, since
the path for avatar images is hashed only by their user-id and a salt,
and as such are reused when a user's avatar is updated.

Alex Vandiver cc9b028312 uploads: Set X-Accel-Redirect manually, without using django-sendfile2.
The `django-sendfile2` module unfortunately only supports a single
`SENDFILE` root path -- an invariant which subsequent commits need to
break.  Especially as Zulip only runs with a single webserver, and
thus sendfile backend, the functionality is simple to inline.

It is worth noting that the following headers from the initial Django
response are _preserved_, if present, and sent unmodified to the
client; all other headers are overridden by those supplied by the
internal redirect[^1]:
 - Content-Type
 - Content-Disposition
 - Accept-Ranges
 - Set-Cookie
 - Cache-Control
 - Expires

As such, we explicitly unset the Content-type header to allow nginx to
set it from the static file, but set Content-Disposition and
Cache-Control as we want them to be.

Alex Vandiver 8e68d68f32 uploads: Be consistent about first arguments to write_local_file.
Enforcing a consistent `type` helps us double-check that we're not
playing fast-and-loose with any file paths for local files.  As noted
in the comment, this is purely for defense-in-depth.

Passing `write_local_file` a consistent `type` requires removing the
"avatars" out of `realm_avatar_and_logo_path` -- which makes it
consistent across upload backends.

This, in turn, requires a compensatory change to zerver.lib.export, to
be explicit that the realm icons are exported from the avatars
directory.  This clarity is likely an improvement.

Alex Vandiver 679fb76acf uploads: Provide our own Content-Disposition header.
sendfile already applied a Content-Disposition header, but the
algorithm may provide both `filename=` and `filename*=` values (which
is potentially confusing to clients) and incorrectly slash-escapes
quotes in Unicode strings.

Django provides a correct implementation, but it is only accessible to
FileResponse objects.  Since the entire point is to offload the
filehandle handling, we cannot use a FileResponse.

Django 4.2 will make the function available outside of FileResponse.
Until then, extract our own Content-Disposition handling, based on
Django's.

We remove the very verbose comment added in d4360e2287, describing
Content-Disposition headers, as it does not add much.

same for all test cases) but that might not be worth the added
complexity.

For alert words, we currently don't send email/push notifications --

here, since desktop notifications do not utilize the presence status

Tested manually that alert word desktop notifications work as expected.

When we implement email/push notifications for alert words (issues #5137
and #13127), we can add new fields like
`notifications_data.alert_word_email_notify`, similar to the existing
`notifications_data.wildcard_mention_email_notify`, which will allow us
to keep the alert word notifiability check inside the dataclass, similar
to how the mentions checks are done currently. So, even when that
feature is implemented, the code which this commit removes would be
unnecessary.

Alex Vandiver 7613928e8a apps: Fix redirect from /apps -> https://zulip.com/apps/.
When this code was moved from being in zerver in 21a2fd482e, it kept
the `if ZILENCER_ENABLED` blocks.  Since ZILENCER and CORPORATE are
generally either both on or both off, the if statement became
mostly-unnecessary.

However, because tests cannot easily remove elements from
INSTALLED_APPS and re-determine URL resolution, we switch to checking
`if CORPORATE_ENABLED` as a guard, and leave these in-place.

The other side effect of this is that with e54ded49c4, most Zulip
deployments started to 404 requests for `/apps` instead of redirecting
them to `https://zulip.com/apps/` since they no longer had any path
configured for `/apps`.  Unfortunately, this URL is in widespread use
in the app (e.g. in links from the Welcome Bot), so we should ensure
that it does successfully redirect.

Add the `/apps` path to `zerver`, but only if not CORPORATE_ENABLED,
so the URLs do not overlap.

Josh Klar c15d066bf5 email-notifs: Use bracketed prefix to indicate a resolved topic.
Some email clients (notably, Gmail Web) support automatically threading
emails together if recipients and subjects match[1]. Manual testing
indicated that prefixing a subject with "[bracketed content]" does not
break this threading behavior, but the added checkmark in a resolved
topic's title does. Before sending an email notification, determine
whether the topic is resolved, and pass this information to the Jinja
template to properly format a threadable email subject.

Josh Klar 69c042bff6 email-notifs: Concatenate topic subject lines only in Jinja.
Previously, stream names and topics (without consideration for their
resolution status) were concatenated in Python-land and passed through
to the template. To more cleanly separate concerns, and to prepare for
accounting for topic resolution status being a third, independent,
component of a subject line, instead pass stream and topic strings
independently to the Jinja template, which can format them as it sees
fit.

Sahil Batra 939a6edf0f settings: Rename helper function to check who can edit topics.
This commit renames "can_edit_topic_of_any_message" function
in models.py to "can_move_messages_to_another_topic" and
"user_can_edit_topic_of_any_message" function in settings_data.js
to "user_can_move_messages_to_another_topic".

This change is done since topic editing permission does not
depend on message sender now and messages are considered same
irrespective of whether the user who is editing the topic had sent
the message or not. This also makes the naming consistent with
what we use for the label of this setting in webapp and how we
describe this action in help documentation.

Previously, we always allowed topic edits when the user themseleves had
sent the message not considering the edit_topic_policy and the 3-day time

according to edit_topic_policy setting and the time limit of 3 days in
addition for users who are not admins or moderators.

Zixuan James Li a3a0103d86 markdown: Calculate linkifier precedence in topics.
This uses the linkifier index among the list of linkifiers in the
replacement as the priority to order the replacement order for
patterns in the topic. This avoids having multiple overlapping matches
that each produce a link.

The linkifier with the lowest id will be prioritized when its pattern
overlaps with another. Linkifiers are prioritized over raw URLs.

Note that the same algorithm is used for local echoing and the
backend markdown processor.

As we have seen no further cases of this in production since #23215,
increase the severity to an error, and switch from returning a
list (which is not type-safe if the function declares a QuerySet
return) to returning the QuerySet without caching.

Failing to store the result in the cache, with an error, seems
superior to raising an exception; in both cases the next request will
redo the work, but we are guaranteed a worse user experience if we 500
the request.

Alex Vandiver f1a8209705 slack_incoming: Fix formatting fixups with overlaps, or at start/end.
The previous regular expression required a `[^\w]` at the start and
end of the match.  This had two unintended effects -- it meant that it
could never match at the start or end of a string, and it meant
that *adjacent* words required *two* non-word characters between them,
as the pattern matches cannot overlap.

Switch to allowing string start/end to anchor the matches, and make
the trailing `[^\w]` be a zero-width look-ahead, to allow the patterns
to overlap.  Also remove the spurious `^` within the inner character
classes, which prevented `*foo^bar*` from matching.  Finally, add
tests to cover the functionality, which was previously untested.

Tim Abbott 0ba63826dd tornado: Disable event compression for mark-as-unread events.
Doing rapid pace mark-as-unread in the Zulip web application, one
observed assertion failures showing that the server would send an
event containing multiple message IDs but only one of the messages
present in the message_details side data structure.

The cause of this was the "virtual events" compression system; two
flags/remove/read events were being combined by simply concatenating
the lists of events, without any attempt to merge the
`message_details` field on those objects.

The immediate fix is to disable virtual events compression for this
event class, but it's not unlikely we'll need to just eliminate the
virtual_events system entirely, because it seems difficult to make it
soundly handle a message whose state for a given flag changes back and
forth while the client is offline.

But we'll leave that for later, since removing that optimization
deserves more discussion than fixing this event corruption bug.

Anders Kaseorg 1735b8863e ruff: Fix B012 return inside finally blocks.
return inside finally blocks causes exceptions to be silenced.
Although these blocks follow blanket ‘except Exception’ handlers, they
do not seem to have a goal of silencing BaseException and exceptions
thrown by the exception handler, so rewrite them to avoid it.
