Otherwise location-only messages
that should be sent every 60 seconds
are never sent because location loop
waits until the end of location streaming
and is only interrupted by location streaming
ending in other chats or being enabled in other chats.
This fixes things for Gmail f.e. Before, `Imap::fetch_move_delete()` was called before looking for
Trash and returned an error because of that failing the whole `fetch_idle()` which prevented
configuring Trash in turn.
The way it was implemented it threw out all remaining messages after finding the next incoming
message. Better use FFIEventTracker functions, they are used in all the tests anyway.
Restart the IO scheduler if needed to make the new config value effective (for `MvboxMove,
OnlyFetchMvbox, SentboxWatch` currently). Also add `set_config_internal()` which doesn't affect
running the IO scheduler. The reason is that `Scheduler::start()` itself calls `set_config()`,
although not for the mentioned keys, but still, and also Rust complains about recursive async calls.
If a Delta Chat message has the Message-ID already existing in the db, but a greater "Date", it's a
resent message that can be deleted. Messages having the same "Date" mustn't be deleted because they
can be already seen messages moved back to INBOX. Also don't delete messages having lesser "Date" to
avoid deleting both messages in a multi-device setting.
Currently `Chat.send_msg()` modifies the source message and returns another message object
equivalent to the source one. That's how it works in the core and thus in Python bindings too.
We do not want all_work_done() to return true immediately
after calling start_io(), but only when connection goes idle.
"Connected" state is set immediately after connecting to the server,
but it does not mean there is nothing to do.
This change make all_work_done() return false
from the Connected state and introduces a new Idle
connectivity state that is only set before connection
actually goes idle. For idle state all_work_done() returns true.
From the user point of view both old Connected state
and new Idle state look the same.
Before, it was shown by UI when the chat is empty, however, in case of
verified groups, this is never the case any longer as the 'e2ee now
guaranteed' is always added.
1:1 chat may be blocked while the contact is not
if 1:1 chat was created as a result of scanning
a verified group join QR code with the contact
as the inviter. In this case 1:1 chat is blocked to hide it
while the contact is unblocked.
It can be used e.g. as a default in the file saving dialog. Also display the original filename in
the message info. For these purposes add Param::Filename in addition to Param::File and use it as an
attachment filename in sent emails.
Webxdc update messages may contain
long lines that get hard-wrapped
and may corrupt JSON if the message
is not encrypted.
base64-encode the update part
to avoid hard wrapping.
This is not necessary for encrypted
messages, but does not introduce
size overhead as OpenPGP messages
are compressed.
The test checks that if webxdc update is too large to
download with the current `download_limit`,
it is applied afterwards when the user manually downloads the update message.
Some Dovecot servers are configured
to alias "INBOX.DeltaChat" and "DeltaChat" to the same folder.
In this case Delta Chat moves new emails from "INBOX"
to "DeltaChat", but then discovers the same mail in "INBOX.DeltaChat"
and tries to move it to "DeltaChat" again.
Each time a MOVE command is issued to move the message
from "INBOX.DeltaChat" to "DeltaChat", the message gets a new UID.
To prevent such IMAP move loop between aliased folders,
we do not move the message if we have already seen it on IMAP,
i.e. we have its Message-ID in the `imap` table.
Note that we do not use `rfc724_mid_exists`,
because it checks the `msgs` table and would consider
BCC-self messages seen even before we see them in the Inbox,
preventing their move to the DeltaChat folder.
Duplicate messages and messages without Message-IDs
are not moved anymore, but this is better
than having an infinite move loop.
Normally the message has UID 1,
but this is not true when account is reused.
In this case the message may be
"Marked messages 2 in folder DeltaChat as seen."
and the test times out waiting for
"Marked messages 1 in folder DeltaChat as seen."
This patch adds new C APIs
dc_get_next_msgs() and dc_wait_next_msgs(),
and their JSON-RPC counterparts
get_next_msgs() and wait_next_msgs().
New configuration "last_msg_id"
tracks the last message ID processed by the bot.
get_next_msgs() returns message IDs above
the "last_msg_id".
wait_next_msgs() waits for new message notification
and calls get_next_msgs().
wait_next_msgs() can be used to build
a separate message processing loop
independent of the event loop.
Async Python API get_fresh_messages_in_arrival_order()
is deprecated in favor of get_next_messages().
Introduced Python APIs:
- Account.wait_next_incoming_message()
- Message.is_from_self()
- Message.is_from_device()
Introduced Rust APIs:
- Context.set_config_u32()
- Context.get_config_u32()
