* ignore status/footer updates from mailinglist messages
mailinglist software often modified existing footers
or adds footers on their own.
therefore,therefore, these footers often do not reflect the status/footer set by the user.
* test status footers not updated from mailinglists
some mailinglists have their name in square brackets prepended to the subject.
we pick up that name and remove the square brackets,
as these do not look good as the chat name in delta chat.
if a mailing list has a sequence of square brackets, we use all of them
(this seems to be okayish, at least i do not know of any complains).
however, the removal of square brackets was not nice for sequences,
resulting in `ml topic] [sub topic`.
this pr removes the square brackets only for the first name
and leave the other ones as is.
* more flexible render_webxdc_status_update_object()
* delay webxdc updates when ratelimit is reached
* inject updates messages to the SMTP loop as needed
this avoids starting several tasks
and allows sending updates out after a restart of the app.
* use mutex to prevent race conditions in status updates
* check ratelimiter only before the sending loop; it won't change until messages are actually sent out
* fix typo
* prefer standard type declaration over turbofish syntax
* use UNIQUE and ON CONFLICT for query smtp_status_updates
* combine DELETE+SELECT to one atomic statement
* as all operations on smtp_status_updates are now atomic, a mutex is no longer needed
* test DELETE+RETURNING statement
* simplify calls to can_send()
* comment about ratelimit boolean in send_smtp_messages()
This makes quotes created by user display properly in other MUAs like
Thunderbird and not start with space in MUAs that don't support format=flowed.
To distinguish user-created quotes from top-quote inserted by Delta
Chat, a newline is inserted if there is no top-quote and the first
line starts with ">".
Nested quotes are not supported, e.g. line starting with "> >" will
start with ">" on the next line if wrapped.
* do not use ratelimiter for bots
i tried some other approaches as having optional ratelimiter
or handle `can_send()` for bots differently,
but all that results in _far_ more code and/or indirections -
esp. as the "bot" config can change and is also persisted -
and the ratelimiter is created
at a point where the database is not yet available ...
of course, all that could be refactored as well,
but this two-liner also does the job :)
* update CHANGELOG
New ratelimiter module counts number of sent messages and calculates
the time until more messages can be sent.
Rate limiter is currently applied only to MDNs. Other messages are
sent without rate limiting even if quota is exceeded, but MDNs are not
sent until ratelimiter allows sending again.
* 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
Not completely sure it's worth it since some other dependencies still
depend on it. Anyway, proc macros are said to be bad for compile times, I just typed out what the proc macro generates and it's only 8 more lines, and we're already doing it this way in e.g. action_by_contact() and collect_texts_recursive() (the latter needs the boxed future both for the trait and for recursion).
* do not wipe info for drafts
* drafts and received webxdc-instances, resent or not, do not trigger info-messages
* test that resending a webxdc does not not add legacy info-messages
* make clippy happy
* update CHANGELOG
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();
}
}
```
* test contact name changes applied everywhere
this test is failing on current master,
a changed authname is set to `contact.authname` but not cached at `chat.name`;
resulting in `dc_chat_get_name()` returning a name
undiscoverable by `dc_get_chatlist(name)`.
* fix: update chat.name on contact.authname changes
* do read contact.display_name from database only of chat.name is empty
* update CHANGELOG
This ensures that no invalid states are possible,
like the one where cancel channel exists, but
no ongoing process is running, or the one where
the ongoing process is not allocated, but
should not be stopped.
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().
Skipping of all [Gmail] folders was introduced to avoid scanning
virtual "[Gmail]/All Mail" folder. However, it also skips Sent and
Spam folders which reside inside [Gmail]. As a result
configured_sentbox_folder becomes unset after folder scan, making it
impossible to watch Sent folder, and Spam folder is never scanned.
This change makes Delta Chat identify virtual Gmail folders by their
flags, so virtual folders are skipped while Sent and Spam folders are
still scanned.
