If the email subject is something like `Fwd:`, it gets stripped to an
empty string, activating the "(no topic)" override. This however leads
to failure if the organization enables the setting forcing every message
to have a topic. Such emails should still go through, so we should just
change the topic value used.
Besides "RE:" and "FWD:", "AW:" (from German "Antwort" for answer) is
another common prefix in email subjects. Let email_mirror automatically
remove it as well.
This commit performs a sweep on the first batch of non API
files to rename "huddle" to "direct_message_group`.
It also renames variables and methods of type -
"huddle_message" to "group_direct_message".
This is a part of #28640
This commit updates code to access name from named_user_group
field which points to the "NamedUserGroup" instead of directly
accessing name from "UserGroup", since name field will only
be present on NamedUserGroup objects in further commits.
Updates translated JsonableError strings that relate to streams
to use channel instead of stream. Separated from other error string
updates as this is a dense area of changes for this rename.
Part of stream to channel rename project.
This is a prep commit to add a 'recipient_users' parameter to
the 'internal_send_huddle_message' function.
'emails' is no longer a required parameter. We can use either
of the 'emails' or 'recipient_users' parameter. 'emails' is
eventually used to fetch 'recipient_users', so if the
'recipient_users' is already available we should use that to
skip database query.
Replaced HUDDLE attribute with DIRECT_MESSAGE_GROUP using VS Code search,
part of a general renaming of the object class.
Fixes part of #28640.

This is preparatory work towards adding a Topic model.
We plan to use the local variable name as 'topic' for
the Topic model objects.
Currently, we use *topic as the local variable name for
topic names.
We rename local variables of the form *topic to *topic_name
so that we don't need to think about type collisions in
individual code paths where we might want to talk about both
Topic objects and strings for the topic name.
This commit adds code to not include original details of senders like
name, email and avatar url in the message objects sent through events
and in the response of endpoint used to fetch messages.
This is the last major commit for the project to add support for
limiting guest access to an entire organization.
Fixes#10970.
This commit adds code to pass all the required arguments to
select_related call for MissedMessageEmailAddress such that
only the required related fields are fetched from the database.
Previously, we did not pass any arguments to select_related,
so all the directly and indirectly related fields were fetched
when many of them were actually not being used and made the
query unnecessarily complex.
Refactors instances of `message_type_name` and `message_type`
that are referring to API message type value ("stream" or
"private") to use `recipient_type_name` instead.
Prep commit for adding "direct" as a value for endpoints with a
`type` parameter to indicate whether the message is a stream or
direct message.
The content of a message is truncated to `MAX_MESSAGE_LENGTH`, which
is 1000 characters. Since the email gateway places attachments at the
very end of the extracted body, that means that they are the first
thing to get truncated off.
That is, if an incoming email message contains 1000 `a`s and an image
attachment, the link that attaches the attachment to the message will
get truncated off, leaving it dangling in the database.
Truncate the message body content separately from the attachment links
which are included at the end of the body.
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.
These limits don't appear to provide useful security benefits, and
they do impact usability because they prevented email-based users from
replying more than once, or from replying to message more than 5 days
old.
Fixes#2755.
Fixes#19994.
These characters are not allowed and trying to create a Zulip message
with those characters throws a JsonableError in check_stream_topic.
We don't want to reject emails with those chars in the subject, so
it's best to just modify it appropriately.
Now that we can assume Python 3.6+, we can use the
email.headerregistry module to replace hacky manual email address
parsing.

These logs were pretty spammy, and there have long been much better
ways to communicate to system administrators that the incoming email
gateway is great, including, most importantly, in the section of the
emails themselves that explains how replying works.
