Hostname resolution may timeout if DNS servers are not responding.
It is also not necessary to resolve fallback ICE server hostnames
if the user is not going to use calls.
Otherwise wrong IMAP client corresponding to a different transport
may pick up the job to mark the message as seen there,
and fail to do it as the message does not exist.
It may also mark the wrong message with the correct folder
and UID, but wrong IMAP server.
There was a comment that group messages should always be downloaded to avoid inconsistent group
state, but this is solved by the group consistency algo nowadays in the sense that inconsistent
group state won't spread to other members if we send to the group.
At urgent request from @hpk42, this adds a config option `team_profile`.
This option is only settable via SQLite (not exposed in the UI), and the
only thing it does is disabling synchronization of seen status.
I tested manually on my Android phone that it works.
Not straigthforward to write an automatic test, because we want to test that something
does _not_ happen (i.e. that the seen status is _not_ synchronized), and
it's not clear how long to wait before we check.
Probably it's fine to just not add a test.
This is what I tried:
```python
@pytest.mark.parametrize("team_profile", [True, False])
def test_markseen_basic(team_profile, acfactory):
"""
Test that seen status is synchronized iff `team_profile` isn't set.
"""
alice, bob = acfactory.get_online_accounts(2)
# Bob sets up a second device.
bob2 = bob.clone()
bob2.start_io()
alice_chat_bob = alice.create_chat(bob)
bob.create_chat(alice)
bob2.create_chat(alice)
alice_chat_bob.send_text("Hello Bob!")
message = bob.wait_for_incoming_msg()
message2 = bob2.wait_for_incoming_msg()
assert message2.get_snapshot().state == MessageState.IN_FRESH
message.mark_seen()
# PROBLEM: We're not waiting 'long enough',
# so, the 'state == MessageState.IN_SEEN' assertion below fails
bob.create_chat(bob).send_text("Self-sent message")
self_sent = bob2.wait_for_msg(EventType.MSGS_CHANGED)
assert self_sent.get_snapshot().text == "Self-sent message"
if team_profile:
assert message2.get_snapshot().state == MessageState.IN_FRESH
else:
assert message2.get_snapshot().state == MessageState.IN_SEEN
```
Currently there is a race between transports
to upload sync messages and delete them from `imap_send` table.
Sometimes mulitple transports upload the same message
and sometimes only some of them "win".
With this change only the primary transport
will upload the sync message.
For multiple transports we will need to run
multiple IMAP clients in parallel.
UID validity change detected by one IMAP client
should not result in UID resync
for another IMAP client.
`login_param` module is now for user-visible entered login parameters,
while the `transport` module contains structures for internal
representation of connection candidate list
created during transport configuration.
It's used in `fetch_existing_msgs()`, but we can remove it and tell users that they need to
move/copy messages from Sentbox to Inbox so that Delta Chat adds all contacts from them. This way
users will be also informed that Delta Chat needs users to CC/BCC/To themselves to see messages sent
from other MUAs.
The motivation is to reduce code complexity, get rid of the extra IMAP connection and cases when
messages are added to chats by Inbox and Sentbox loops in parallel which leads to various message
sorting bugs, particularly to outgoing messages breaking sorting of incoming ones which are fetched
later, but may have a smaller "Date".
We already have both rand 0.8 and rand 0.9
in our dependency tree.
We still need rand 0.8 because
public APIs of rPGP 0.17.0 and Iroh 0.35.0
use rand 0.8 types in public APIs,
so it is imported as rand_old.
We do not try to delete resent messages
anymore. Previously resent messages
were distinguised by having duplicate Message-ID,
but future Date, but now we need to download
the message before we even see the Date.
We now move the message to the destination folder
but do not fetch it.
It may not be a good idea to delete
the duplicate in multi-device setups anyway,
because the device which has a message
may delete the duplicate of a message
the other device missed.
To avoid triggering IMAP busy move loop
described in the comments
we now only move the messages
from INBOX and Spam folders.
I have logs from a user where messages are prefetched for long minutes, and while it's not a problem
on its own, we can't rely that the connection overlives such a period, so make
`fetch_new_messages()` prefetch (and then actually download) messages in batches of 500 messages.
Ignoring `receive_imf_inner()` errors, i.e. silently skipping messages on failures, leads to bugs
never fixed. As for temporary I/O errors, ignoring them leads to lost messages, in this case it's
better to bubble up the error and get the IMAP loop stuck. However if there's some logic error, it's
better to show it to the user so that it's more likely reported, and continue receiving messages. To
distinguish these cases, on error, try adding the message as partially downloaded with the error set
to `msgs.error`, this way the user also can retry downloading the message to finally see it if the
problem is fixed.
Actually this leads to fetching messages only from watched folders and Spam. Motivation:
- At least Gmail has virtual folders which aren't correctly detected as such, e.g. "Sent".
- At least Gmail has many virtual folders and scanning all of them takes significant time, 5-6 secs
in median for me. This slows down receiving new messages and consumes battery.
- Delta Chat shouldn't fetch messages from folders potentially created by other apps for their own
purposes. NB: All compatible Delta Chat forks should use the "DeltaChat" folder as mvbox.
- Fetching from folders that aren't watched, e.g. from "Sent", may lead to message ordering issues.
Follow-up to https://github.com/chatmail/core/pull/7125: We now have a
mix of non-async (parking_lot) and async (tokio) Mutexes used for the
connectivity. We can just use non-async Mutexes, because we don't
attempt to hold them over an await point. I also tested that we get a
compiler error if we do try to hold one over an await point (rather than
just deadlocking/blocking the executor on runtime).
Not 100% sure about using the parking_lot rather than std Mutex, because
since https://github.com/rust-lang/rust/issues/93740, parking_lot
doesn't have a lot of advantages anymore. But as long as iroh depends on
it, we might as well use it ourselves.
Connection sometimes fails while processing FETCH
responses. In this case `fetch_new_messages` exits early
and does not advance next expected UID even if
some messages were processed.
This results in prefetching the same messages
after reconnection and log messages
similar to
"Not moving the message ab05c85a-e191-4fd2-a951-9972bc7e167f@localhost that we have seen before.".
With this change we advance next expected UID
even if `fetch_new_messages` returns a network error.
This change introduces a new type of contacts
identified by their public key fingerprint
rather than an e-mail address.
Encrypted chats now stay encrypted
and unencrypted chats stay unencrypted.
For example, 1:1 chats with key-contacts
are encrypted and 1:1 chats with address-contacts
are unencrypted.
Groups that have a group ID are encrypted
and can only contain key-contacts
while groups that don't have a group ID ("adhoc groups")
are unencrypted and can only contain address-contacts.
JSON-RPC API `reset_contact_encryption` is removed.
Python API `Contact.reset_encryption` is removed.
"Group tracking plugin" in legacy Python API was removed because it
relied on parsing email addresses from system messages with regexps.

fetch_existing option is not enabled in existing clients
and does not work with encrypted messages
without importing the key into a newely created account.
