because many linebreaks seem to cause the chat open delay on deltachat-ios

Co-authored-by: link2xt <link2xt@testrun.org>
* force a reason when calling `set_msg_failed()`
the string is displayed to the user,
so even _some_ context as "NDN without further details"
is better than an empty string.
* make clippy happy
* add CHANGELOG entry
* clarify webxdc reference wrt info-messages
* add from_id parameter to add_info_msg_with_cmd()
* flag webxdc-info-messages as such
* set from_id to sender for webxdc-info-messages
* test additional webxdc info properties
* do not add series of similar info messages
instead, if on adding the last info message
is already from the same webxdc and sender,
just update the text
* test cleanup of webxdc info messages series
* update changelog
* make clippy happy
there is no real complexity in the args,
so allowing one more arg is probably fine.
if really wanted, we can refactor the function in another pr;
this pr is already complex enough :)
* use cleaner function names and comments
* clarify CHANGELOG
mimeparser now handles try_decrypt() errors instead of simply logging
them. If try_decrypt() returns an error, a single message bubble
with an error is added to the chat.
The case when encrypted part is found in a non-standard MIME structure
is not treated as an encryption failure anymore. Instead, encrypted
MIME part is presented as a file to the user, so they can download the
part and decrypt it manually.
Because try_decrypt() errors are handled by mimeparser now,
try_decrypt() was fixed to avoid trying to load private_keyring if the
message is not encrypted. In tests the context receiving message
usually does not have self address configured, so loading private
keyring via Keyring::new_self() fails together with the try_decrypt().
This change is aimed at decoupling parsing and
add_parts() stages to eventually separate parsing
from database changes and pipeline message parsing and
decryption.
This seems not only wasteful but genuinly has the risk someone makes
their device useless by accidentally adding a huge file.
This also re-structures the checks a little: The if-conditions are
flattened out and cheap checks are done before more expensive ones.
This makes the contact ID its own newtype instead of being a plain
u32. The change purposefully does not yet try and reap any benefits
from this yet, instead aiming for a boring change that's easy to
review. Only exception is the ToSql/FromSql as not doing that yet
would also have created churn in the database code and it is easier to
go straight for the right solution here.
Message-IDs are now retrieved only during fetching and saved into imap
table. dc_receive_imf_inner does not attempt to extract the Message-ID
anymore.
For messages without Message-ID the ID is now generated in
imap::fetch_new_messages rather than dc_receive_imf_inner,
so the same ID is used in the imap table (maintained by the imap
module) and msgs table (maintained by dc_receive_imf module).
Message-ID generation based on the Date, From and To field hashing has
been replaced with a simple dc_create_id() to avoid retrieving Date,
From, and To fields in the imap module, as it's hard to test that it
stays compatible between Delta Chat versions in this module. This
breaks jump-to-quote for quoted messages without Message-ID, which is
not critical.
Also prefetch X-Microsoft-Original-Message-ID, so retrieval of
duplicate messages with X-Microsoft-Original-Message-ID can be skipped
like it is done for messages with Message-ID header.
`imap` table maps Message-IDs to UIDs on the server. `dc_receive_imf`
no longer gets the UID of the message as an argument and does not
insert the folder and UID of the message into the `msgs`
table. `server_folder` and `server_uid` columns in `msgs` table are
deprecated.
MoveMsg and DeleteMsgOnImap jobs are removed. Now messages are moved
and deleted only in the `fetch_move_delete` procedure that consults
the `target` column of the `imap` table to determine where the message
should go.
Where the message should go is determined after prefetching by the
`imap::target_folder()` procedure. Messages are only downloaded once
they reach their target folder to avoid race conditions in multidevice
setting, such as:
1. One device trying to FETCH the message while the other tries to
MOVE it.
2. One device marking the message as \Seen in the Inbox while the
other has already copied unseen message to the Movebox and is going to
delete the \Seen message in the Inbox.
3. Device downloads the message from the Inbox while there are newer
messages in the Movebox placed there by the other device, thus
processing the messages out of order.
They contain X-MSExch-Correlation-Key header, but no
Original-Message-ID, so they cannot be used to find the original
message, but we want to recognize them as MDN nevertheless to assign
them to the trash chat.
Update gossiped_timestamp when someone else sends autocrypt gossip in
the group, so we postpone sending gossip again ourselves.
- Warn about failures to parse Autocrypt-Gossip header
- Move gossip-related methods into ChatId impl
- Fix a "gossi_pp_ed" typo

- Fix a typo: s/DC_ELLIPSE/DC_ELLIPSIS/
- Do not truncate the text when loading from the database.

This bug sometimes results in sending read receipts to self in
multi-device setups.
It happens consistently in a setup where the first device is
configured to move messages to DeltaChat folder and the second device
is not. When both devices receive BCC-self message simultaneously, the
first device moves the message to DeltaChat folder, while the second
device tries to mark the message as seen in the Inbox. Regardless of
whether the second device marks the message as seen successfully or
fails because the message is already moved by the first device,
`Job.markseen_msg_on_imap()` sends the read receipt to the From
address.
Previously system messages were always added to the end of the chat,
even if the message triggering them was sent earlier. This is
especially important for messages about disappearing timer reset
triggered by classic email messages, as they should be placed right
after the message resetting the timer.
Contact request chats are not merged into a single virtual "deaddrop"
chat anymore. Instead, they are shown in the chatlist the same way as
other chats, but sending of messages to them is not allowed and MDNs
are not sent automatically until the chat is "accepted" by the user.
New API:
- dc_chat_is_contact_request(): returns true if chat is a contact
request. In this case option to accept and block the chat via
dc_accept_chat() and dc_block_chat() should be shown in the UI.
- dc_accept_chat(): accept contact request and unblock the chat
- dc_block_chat(): decline contact request and block the chat
Removed API:
- dc_create_chat_by_msg_id(): deprecated 2021-02-07 in favor of
dc_decide_on_contact_request()
- dc_marknoticed_contact(): deprecated 2021-02-07 in favor of
dc_decide_on_contact_request()
- dc_decide_on_contact_request(): this call requires a message ID from
deaddrop chat as input. As deaddrop chat is removed, this call can't
be used anymore.
- dc_msg_get_real_chat_id(): use dc_msg_get_chat_id() instead, the
only difference between these calls was in handling of deaddrop chat
- removed DC_CHAT_ID_DEADDROP and DC_STR_DEADDROP constants
