This allows account manager to construct a single event channel and
inject it into all created contexts instead of aggregating events from
separate event emitters.
I added this poison_sender and poison_receiver stuff back when we had event listeners (which were called "sinks", too, but anyway), i.e. user-definable closures that were run in the events loop. This was to make sure that the test fails if the closure panics. But since we don't have them anymore and this code isn't supposed to panic anyway:
```rust
while let Some(event) = events.recv().await {
for sender in senders.read().await.iter() {
sender.try_send(event.clone()).ok();
}
}
```
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.
The state bob needs to maintain during a secure-join process when
exchanging messages used to be stored on the context. This means if
the process was killed this state was lost and the securejoin process
would fail. Moving this state into the database should help this.
This still only allows a single securejoin process at a time, this may
be relaxed in the future. For now any previous securejoin process
that was running is killed if a new one is started (this was already
the case).
This can remove some of the complexity around BobState handling: since
the state is in the database we can already make state interactions
transactional and correct. We no longer need the mutex around the
state handling. This means the BobStateHandle construct that was
handling the interactions between always having a valid state and
handling the mutex is no longer needed, resulting in some nice
simplifications.
Part of #2777.
* Add AcManager
See https://github.com/deltachat/deltachat-core-rust/pull/2901#issuecomment-998285039
This reduces boilerplate code again therefore, improving the
signal-noise-ratio and reducing the mental barrier to start
writing a unit test.
Slightly off-topic:
I didn't add any advanced functions like `manager.get("alice");` because
they're not needed yet; however, once we have the AcManager we can
think about fancy things like:
```rust
acm.send_text(&alice, "Hi Bob, this is Alice!", &bob);
```
which automatically lets bob receive the message.
However, this may be less useful than it seems at first, since most of
the tests I looked at wouldn't benefit from it, so at least I won't do
it until I have a test that would benefit from it.
* Remove unnecessary RefCell
* Rename AcManager to TestContextManager
* Don't store TestContext's in a vec for now as we don't need this; we can re-add it later
* Rename acm -> tcm
I considered removing it from the context by default, but the
migration test really wants to have the tracker initialised from the
very first event and not after the context is initialised. It is
easier for now to leave it hardcoded instead of adding an API to
explicitly require enabling it via the builder.
This replaces the EventSink callbacks with simple channel senders.
This simplifies the TestContext a lot as that is much simpler to
handle. It then also removes the special-casing of the LogSink since
it now is another even sender, only injected at the very start.
There are too many ways to create a TestContext, this introduces a
TestContextBuilder to try and keep this shorter. It also cleans up
the existing constructors keeping only the commonly used ones.
Without this the test output is written somewhere random and ends up
in the wrong test report. This buffers all the log output and prints
it inside the test on dropping the LogSink, or on dropping the
TestContext if no explicit LogSink was created.
`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.
ASCII armored keys can be easily generated with `sq key generate` and
used to encrypt and decrypt test messages with `sq` and `gpg` without
converting them to binary using `base64 -d` first.
Before this PR, when a test failed, we often got:
```
thread panicked while processing panic. aborting.
error: test failed, to rerun pass '-p deltachat --lib'
Caused by:
process didn't exit successfully: `/home/user/deltachat-android/jni/deltachat-core-rust/target/debug/deps/deltachat-33648fc4aaad608c 'contact::tests::test_selfavatar_changed_event' --nocapture` (signal: 4, SIGILL: illegal instruction)
```
instead of the error message and stack trace.
This PR fixes this.
* Add DC_EVENT_SELFAVATAR_CHANGED
* Add test.
Unfortunately I can't easily also test that the avatar is not copied
from unencrypted messages:
In the second encrypted message, the avatar would not be sent again
then, because we only send avatars once a day or so.

It turns out that it's pretty easy to distinguish between lots of states (currently Error/NotConnected, Connecting…, Getting new messages… and Connected). What's not that easy is distinguishing between an actual error and no network, because if the server just doesn't respond, it could mean that we don't have network or that we are trying ipv6, but only ipv4 works.
**WRT debouncing:**
Sending of EVENT_CONNECTIVITY_CHANGED is not debounced, but emitted every time one of the 3 threads (Inbox, Mvbox and Sentbox) has a network error, starts fetching data, or is done fetching data.
This means that it is emitted:
- 9 times when dc_maybe_network() is called or we get network connection
- 12 times when we lose network connection
Some measurements: dc_get_connectivity() takes a little more than 1ms (in my measurements back in March), dc_get_connectivity_html() takes 10-20ms. This means that it's no immmediate problem to call them very often, might increase battery drain though. For the UI it may be a lot of work to update the title everytime; at least Android is smart enough to update the title only once.
Possible problems (we don't have to worry about them now I think):
- Due to the scan_folders feature, if the user has lots of folders, the state could be "Connecting..." for quite a long time, generally DC seemed a little unresponsive to me because it took so long for "Connecting..." to go away. Telegram has a state "Updating..." that sometimes comes after "Connecting...".
To be done in other PRs:
- Better handle the case that the password was changed on the server and authenticating fails, see https://github.com/deltachat/deltachat-core-rust/issues/1923 and https://github.com/deltachat/deltachat-core-rust/issues/1768
- maybe event debouncing (except for "Connected" connectivity events)
fix https://github.com/deltachat/deltachat-android/issues/1760
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.
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
fix#2254: if the DB was closed without calling stop_io() and then an interrupt arrives (e.g. incoming message), the db was corrupted.
* Add result.log() for logging with less boilerplate code
* Bugfix: Resultify housekeeping() to make it abort if the db is closed instead of just deleting everything
* Require the UI to call dc_stop_io() before backup export
* Prepare a bit better for closed-db: Resultify get_uidvalidity and get_uid_next and let job::load_next() wait until the db is open
About the bug (before this PR):
if the DB was closed without calling stop_io() and then an interrupt arrives (e.g. incoming message):
- I don't know if it downloads the message, but of course at some point the process of receiving the message will fail
- In my test, DC is just in the process of moving a message when the imex starts, but then can't delete the job or update the msg server_uid
- Then, when job::load_next() is called, no job can be loaded. That's why it calls `load_housekeeping_job()`. As `load_housekeeping_job()` can't load the time of the last housekeeping, it assumes we never ran housekeeping and returns a new Housekeeping job, which is immediately executed.
- housekeeping can't find any blobs referenced in the db and therefore deletes almost all blobs.

* 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

- doc fixes
- make BobStateHandle safer by moving the state out of the handle.
- handle more match cases explicit in BobState returns
- fewer mutable variables
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.
