Do not process names, avatars, location XMLs, message signature
etc. for duplicate messages.
Previously only `add_parts` was stopped early, but not
`dc_receive_imf`. Also, `dc_receive_imf` processed From: and To:
fields and applied names to contacts even before checking the
Message-ID.
Fake Message-ID generation procedure is changed to operate on raw
header values to avoid interacting with the database.
Raw MIME messages may contain non-ASCII characters. Attempting to
store them as TEXT by using String::from_utf8_lossy results in
non-ASCII characters being replaced with Unicode U+FFFD "REPLACEMENT
CHARACTER" which is later incorrectly decoded when attempting to parse
`mime_headers` content into HTML.
Previously chats created by outgoing classic emails went into contact
requests (deaddrop). Outgoing messages are not shown in contact
requests, so created chat was not shown anywhere. With this fix chat
is created both for outgoing classic emails and outgoing chat emails.
systemli.org seems not to include Received: header in messages sent to
self, including BCC-self and messages sent to Saved message chat. This
results in all these messages not being displayed on other devices in
multi-device setting. To work around this problem we restrict draft
detection based on Received: header to classical mails.
Delta Chat already implements proper draft detection based on the
\Draft message flag and \Drafts folder flag. However, Thunderbird does
not set \Draft flag when message is stored as "Template". To make
draft detection for Thunderbird more robust, in case Received: header
check is removed altogether later, we check for X-Mozilla-Draft-Info
header which Thunderbird sets both for "Drafts" and "Templates".
* Add failing test for #2369
* Completely ignore Drafts folder
fix#2369
* Also ignore messages that have the Draft flag set but are not in the Drafts folder
Using `impl AsRef<str>` as the argument instead of `&str` makes it
possible to call the function with `&str`, `String` and other types
that implement `AsRef` trait.
The cost of it is that compiled binary contains mulitple versions of
the same function, one for each variant of types. If function contains
multiple generic `impl AsRef` arguments, the number of versions possibly
compiled into binary grows exponentially with the number of arguments.
Simple way to avoid it is to call `.as_ref()` on the caller side to
convert the argument to `&str`. In most cases even adding a `&` and
relying on `Deref` coercion is sufficient.
This patch changes many functions that accepted `impl AsRef<str>` and
`impl AsRef<Path>` to accept `&str` and `&Path` instead.
In some places `.clone()` calls are removed. Calling `.clone()` on
`String` and passing `String` to a function accepting `impl
AsRef<str>` is completely unnecessary as `&str` reference could be
passed instead. There is no clippy warning against it yet, but
changing argument type to `&str` allowed to find these cases.
The result of debloating is not impressive, several hundred kilobytes
are saved, which is about 3% of the `.so` binary, but the code is
cleaner too.
This moves the module-level lookup and creation functions to the
types, which make the naming more consistent. Now the lookup_* get_*
and create_* functions all behave similarly.
Peraps even more important the API of the lookup now allows
distinguishing failure from not found. This in turn is important to
be able to remove reliance on a ChatId with a 0 or "unset" value. The
locations where this ChatId(0) is still used is in database queries
which should be solved in an independed commit.
This introduces the explicit ChatIdBlocked struct to more explicitly
create a chat with a blocked status. It also adds a common shortcut
to ChatId itself which is more natural to use in many cases.
* Remove sql::error submodule
Use anyhow errors instead.
* Remove explicit checks for open SQL connection
An error will be thrown anyway during attempt to execute query.
* Don't use `with_conn()` and remove it
* Remove unused `with_conn_async`
* Resultify markseen_msgs
This feature is similar to existing avatar synchronization.
Whenever encrypted BCC-to-self copy of chat message is received, status
setting is updated with the signature of the message.
fix #2073fix#2292 (I think)
- Messages can be assigned to any chat by the References and In-Reply-To, also to 1:1 chats; this has higher priority than the group id because with ad-hoc groups, it can happen that two devices have different group ids for the same conversation thread.
- If `From` is not in the chat (we call this "shadow sender"), `OverrideSenderDisplayname` is set. This communicates to the UI that:
- A `~`should be added in front of the sender's displayname.
- Also in 1:1 chats, the sender's displayname and avatar is shown, as if this was a group.
The "Unknown sender for this chat" messages are completely removed for unprotected groups.
For protected chats, everything stays as it was before.
POSTPONED:
- Maybe (if it turns out to be still necessary):
- The ad-hoc group id is computed by the the References, instead of the member list, as it is currently done
- How do we prevent that the message can't be assigned to the correct chat as the parent message was deleted?
Switches from rusqlite to sqlx to have a fully async based interface
to sqlite.

save subject for messages:
- new api `dc_msg_get_subject()`,
- when quoting, use the subject of the quoted message as the new subject, instead of the
last subject in the chat
the test has multiple text parts because
the content text is signed and
the mailinglist software wants to add some text
(and cannot alter signed part without breaking the signature)
* add test for mailchimp mailinglists
* pass MimeMessage to create_or_lookup_mailinglist() (as of the other create*() routines) to allow more flexible name processing; document the function
* get mailing list name for mailchimp from From:-header
* make clippy happy
* add comment to '.list-id.mcsv.net' suffix
This changes the internal stock strings API to be more strongly typed,
ensuring that the caller can not construct the stock string in the
wrong way.
The old approach left it to the callers to figure out how a stock
string should be created, now each stock string has their specific
arguments and callers can not make mistakes. In particular all the
subtleties and different ways of calling stock_system_msg() disappear.
This could not use a trait for stock strings, as this would not allow
having per-message typed arguments. So we needed a type per message
with a custom method, only by convention this method is .stock_str().
The type is a enum without variants to avoid allowing someone to
create the type.
Sadly the fallback string and substitutions are still far away from
each other, but it is now only one place which needs to know how to
construct the string instead of many.
The following rules apply now:
1. "name" column is only updated manually and never over the network
2. "authname" column is only updated over the network and never manually
3. Displayname is a "name" if it is non-empty, otherwise it is "authname".
This fixes a known (pytest.xfail) problem of "name" being changed over
the network when user has set it to non-empty string manually.
This also fixes the problem when "name" and "authname"
became unsynchronized accidentally, when they were equal and then
Origin::IncomingUnknownTo update arrived, setting "name" but not
"authname". Rust regression test is added for this case.
* Copypaste-merge my old work
* Start implementing mailinglists the new way
* Create pseudo contact
* Fine-tune docs
* Remove some unnecessary changes
* style
* Make a stock str
* Fix a crash. Yes, this line caused a panic when reconfiguring on Android
(without a reasonable error log). Also, I could not receive any messages
anymore.
* rfmt
* Add tests and make them pass
* Even more tests
* rfmt
* Enhance test and fix bug
* Don't update the sender name when prefetching because maybe it's a mailing list
* Use an enum instead of numbers for the decision
* Don't remove anyone from mailing lists
* Fix bug in the regex
* Adjust error msg
* Compile error after rebase
* Correctly emit event
* Add dc_msg_is_mailing_list so that you can find out whether messages in the deaddrop belong to mailing lists.
* Add received headers to unit tests
* Comments, small tweaks
* Use dc_msg_get_override_sender_name instead of dc_msg_get_sender_name
* Add dc_msg_get_sender_first_name() because sometimes the first name was not correctly shown in mailing lists
* small fixes, don't let the user modify mailing list groups
* Hide contacts for addresses like noreply@github.com and reply+AEJ...@reply.github.com
When testing mailing lists, I noticed that sometimes a mailing list
contact got a name (like, hocuri <noreply@github.com>). It turned out
that ages ago, I had accidentally written an email to - in this example
- hocuri <noreply@github.com> and it had been added to the contacts
list.
This hides email addresses from the contacts list that are obviously not
meant to be written at and prevents updating the names.
* Comment, clippy
* Replace u32 with ChatId
* Resolve lost of small issues from the reviews
* remove dc_msg_get_sender_first_name
* add dc_msg_get_real_chat_id()
this allows to check if a contact request belongs to a mailing list
and to show name/avatar/whatever of the mailinglist.
another approach was to duplicate some chat-apis for messages
(eg. dc_msg_is_mailing_list()) however that would require far more new apis.
the idea to change the behavior of dc_msg_get_chat_id() would be
more clean, however, that easily breaks existing implementations
and can led to hard to find bugs.
* remove now unused Message.is_mailing_list()
* if a name for a mailing list is missing, use List-ID
* fix comment
* fix error message
* document how dc_get_chat_contacts() works for mailing lists
* refine decide api (#2185)
* add DC_DECIDE* constants to deltachat.h, tweak documentation
* use StartChat/Block/NotNow instead of Yes/Never/NotNow
* decide_on_contact_request works on ctx/msg-id
functions working on message-objects
usually do not read or write directly on the database.
therefore, decide_on_contact_request()
should not work with message-objects as well,
it is even a bit misleading, as eg. chat-id of the object is not modified.
instead, the function works on context,
similar to dc_send_msg(), dc_create_chat() and so on.
for now, i moved it to context, could maybe be part od MsgId.
* Update src/chatlist.rs

* refine documentation
* re-add accidentally deleted Param::MailingList
* remove pseudo-contact in domain @mailing.list
1. the pseudo-contact was added to the mailing list contacts,
which is not needed.
might be that we want to add the recent contacts there in a subsequent pr
(we do not know all contacts of a mailing list)
2. the pseudo-contact was used to block
mailing lists; this is done by setting the chat to Blocked::Manually now
3- the pseudo-contact was used for unblocking;
as it is very neat not to require additional ui for mailing list unblocking,
might be that we introduce a similar pseudo-contact for this limited purpose
in a subsequent pr, however, the pseudo-contact needs to exist only
during unblocking then, maybe also the special domain is not needed,
we'll see :)
* Move dc_decide_on_contact_request() up to the dc_context section as it's a member of dc_context now
More specifically, to the "handle messages" section
* re-introduce Chattype::Mailinglist (#2195)
* re-introduce Chattype::Mailinglist
* exhaustive chattype-check in fetch_existing_msgs() and get_summary2()
* exhaustive chattype-check in ndn_maybe_add_info_msg()
* exhaustive chattype-check in message::fill()
* remove dc_chat_is_mailing_list() from ffi

This introduces a state machine which takes care of managing the
handshake transitions in the secure-join protocol. This separates
user interactions from the protocol state handling.
This means that while handling the protocol state there are a bunch of
failures no longer possible due to all state information being
guaranteed to be present. As part of this the QR-code state has been
extracted from the generic Lot structure to something suitable just
for the SecureJoin protocol.
A LogSink has been added to the testing tools allowing log messages to
be correctly displayed on test failures.
