Four new APIs `add_transport_from_qr()`, `add_transport()`,
`list_transports()`, `delete_transport()`, as described in the draft at
"API".
The `add_tranport*()` APIs automatically stops and starts I/O; for
`configure()` the stopping and starting is done in the JsonRPC bindings,
which is not where things like this should be done I think, the bindings
should just translate the APIs.
This also completely disables AEAP for now.
I won't be available for a week, but if you want to merge this already,
feel free to just commit all review suggestions and squash-merge.
Found and fixed a bug while investigating
https://github.com/chatmail/core/issues/6656. It's not the same bug,
though.
Steps to reproduce this bug:
- Create a new profile
- Transfer it to a second device
- Send a message from the first device
- -> It will never arrive on the second device, instead a warning will
be printed that you are using DC on multiple devices.
The bug was that the key wasn't created before the backup transfer, so
that the second device then created its own key instead of using the
same key as the first device.
In order to regression-test, this PR now changes `clone()` to use "Add
second device" instead of exporting and importing a backup. Exporting
and importing a backup has enough tests already.
This PR also adds an unrelated test `test_selfavatar_sync()`.
The bug was introduced by https://github.com/chatmail/core/pull/6574 in
v1.156.0
WebSocket support is not used
and is not maintained. It still uses
outdated axum 0.7 version
and does not have any authentication.
Delta Chat Desktop has a new browser target
that implements WebSocket support on top
of stdio server, supports blobs
and is tested in CI.
When it is possible to test that no unhidden contact
is creating by looking through the contact list
or get the contact ID as the from_id of received message,
do it to avoid acidentally creating a contact
or changing its origin before testing.
async-compression 0.4.21 fixes a bug in the encoder
where it did not flush all the internal state sometimes,
resulting in IMAP APPEND command timing out
waiting for response when uploading large sync messages.
See <https://github.com/Nullus157/async-compression/pull/333>
for details.
this PR deletes all known messages belonging to a chat when the chat is
deleted.
this may not be an exhaustive list as a client might not know all
message-ids (eg. when using different times for "delete from device").
in this case, other devices may know more IDs. otherwise, the chatmail
server will eventually clean up at some point. for non-chatmail, this is
up to the user then.
the deletion sql commands were inspired by
[`delete_msgs_ex`](https://github.com/chatmail/core/blob/main/src/message.rs#L1743)
(in fact, [a first
try](https://github.com/chatmail/core/compare/r10s/clear-chat-on-delete)
was adapting that part, however, that seems less performant as lots of
sql commands are needed)
successor of #5007
SecureJoin and importing a vCard are the primary
ways we want to support for creating contacts.
Typing in an email address and relying on Autocrypt
results in sending the first message unencrypted
and we want to clearly separate unencrypted and encrypted
chats in the future.
To make the tests more stable, we set up test contacts
with vCards as this always immediately
results in creating a single encrypted chat
and this is not going to change.
up to now, avatars were restricted to 20k, 256x256 pixel.
resulting in often poor avatar quality.
(the limitation comes from times
where unencrypted outlook inner headers were a thing;
this has changed meanwhile)
to increase quality while keeping a reasonable small size,
for "balanced quality",
we increase the allowed width to 512x512 and the allowed size to 60k.
for "worse quality", things stay unchanged at 128x128 pixel and 20k.
Currently broadcast lists creation is synced across devices. Groups creation, in some means, too --
on a group promotion by a first message. Otoh, messages deletion is synced now as well. So, for
feature-completeness, sync chats deletion too.
Say in the README that cargo-bolero@0.8.0
should be installed as newer versions
do not work currently.
Update `mailparse` to 0.16.0
because this is what Delta Chat currently uses.
I also added fuzzer outputs to .gitignore
Add "Chat-Group-Name-Timestamp" message header and use the last-write-wins logic when updating group
names (similar to group member timestamps). Note that if the "Chat-Group-Name-Changed" header is
absent though, we don't add a system message (`MsgGrpNameChangedBy`) because we don't want to blame
anyone.
Replacing default key
when a profile is already part of
verified groups results in
`[The message was sent with non-verified encryption. See 'Info' for more details]`
messages for other users.
It is still possible
to import the default key before
Delta Chat generates the key.
When there is a broken group (which might happen with multi-transport),
people want to leave it.
The problem is that every "Group left" message notifies all other
members and pops up the chat, so that other members also want to leave
the group.
This PR makes it so that "Group left" messages don't create a
notification, don't cause a number-in-a-cirle badge counter on the chat,
and don't sort up the chat in the chatlist.
If a group is deleted, then the group won't pop up when someone leaves
it; this worked fine already before this PR, and there also is a test
for it.
Instead of being trashed, the message containing a reaction remains in the chat, hidden and InFresh. When the chat is opened, it will be marked as Seen on the server, so that a second device removes the notifications for the reaction.
Close https://github.com/deltachat/deltachat-core-rust/issues/6210.
Also, this adds a benchmark.
Now that we are deduplicating everywhere, we can get rid of some code.
The old python bindings did not get an optional `name` parameter because
they are deprecated anyway, but it would be easy to add it.
> _greetings from the ice of the deutsche bahn 🚂🚃🚃🚃 always a pleasure to
see how well delta chat meanwhile performs in bad networks :)_
this PR adds an API to request other chat members to replace the message
text of an already sent message. scope is mainly to fix typos. this
feature is known from whatsapp, telegram, signal, and is
[requested](https://support.delta.chat/t/retract-edit-sent-messages/1918)
[since](https://support.delta.chat/t/edit-messages-in-delta-chat/899)
[years](https://github.com/deltachat/deltachat-android/issues/198).
technically, a message with an
[`Obsoletes:`](https://datatracker.ietf.org/doc/html/rfc2076#section-3.6)
header is sent out.
```
From: alice@nine
To: bob@nine
Message-ID: 2000@nine
In-Reply-To: 1000@nine
Obsoletes: 1000@nine
Edited: this is the new text
```
the body is the new text, prefixed by the static text `Edited:` (which
is not a header). the latter is to make the message appear more nicely
in Non-Delta-MUA. save for the `In-Reply-To` header. the `Edited:`
prefix is removed by Delta Chat on receiving.
headers should be protected and moved to e2ee part as usual.
corrected message text is flagged, and UI should show this state, in
practise as "Edited" beside the date.
in case, the original message is not found, nothing happens and the
correction message is trashes (assuming the original was deleted).
question: is the `Obsoletes:` header a good choice? i _thought_ there is
some more specifica RFC, but i cannot find sth. in any case, it should
be an header that is not used otherwise by MUA, to make sure no wanted
messages disappear.
what is NOT done and out of scope:
- optimise if messages are not yet sent out. this is doable, but
introduces quite some cornercaes and may not be worth the effort
- replaces images or other attachments. this is also a bit cornercasy
and beyond "typo fixing", and better be handled by "delete for me and
others" (which may come soon, having the idea now, it seems easy :)
- get edit history in any way. not sure if this is worth the effort,
remember, as being a private messenger, we assume trust among chat
members. it is also questionable wrt privacy, seized devices etc.
- add text where nothing was before; again, scope is "typo fixing",
better avoid cornercases
- saved messages are not edited (this is anyway questionable)
- quoted texts, that are used for the case the original message is
deleted, are not updated
- edits are ignored when the original message is not there yet (out of
order, not yet downloaded)
- message status indicator does not show if edits are sent out or not -
similar to reactions, webxdc updates, sync messages. signal has the same
issue :) still, connectivity should show if there are messages pending

This makes it so that files will be deduplicated when using the JsonRPC
API.
@nicodh and @WofWca you know the Desktop code and how it is using the
API, so, you can probably tell me whether this is a good way of changing
the JsonRPC code - feel free to push changes directly to this PR here!
This PR here changes the existing functions instead of creating new
ones; we can alternatively create new ones if it allows for a smoother
transition.
This brings a few changes:
- If you pass a file that is already in the blobdir, it will be renamed
to `<hash>.<extension>` immediately (previously, the filename on the
disk stayed the same)
- If you pass a file that's not in the blobdir yet, it will be copied to
the blobdir immediately (previously, it was copied to the blobdir later,
when sending)
- If you create a file and then pass it to `create_message()`, it's
better to directly create it in the blobdir, since it doesn't need to be
copied.
- You must not write to the files after they were passed to core,
because otherwise, the hash will be wrong. So, if Desktop recodes videos
or so, then the video file mustn't just be overwritten. What you can do
instead is write the recoded video to a file with a random name in the
blobdir and then create a new message with the new attachment. If
needed, we can also create a JsonRPC for `set_file_and_deduplicate()`
that replaces the file on an existing message.
In order to test whether everything still works, the desktop issue has a
list of things to test:
https://github.com/deltachat/deltachat-desktop/issues/4498
Core issue: #6265

This hopefully does not trigger Apple spam filter
which seems to pass thorugh Message-IDs with hyphens.
It is not confirmed, but better blend in
by mimicking existing popular email
where possible.
With iOS and Desktop copying the file to a to a temp file with the name
of `get_filename()`, it should be sanitized first.
The PR can be reviewed commit-by-commit or all at once.
This task is not guaranteed to be cancellation-safe
and provides a stop token for safe cancellation instead.
We should always cancel the task properly
and not by racing against another future.
Otherwise following call to Handle.done()
may work on IMAP session that is in the middle
of response, for example.
this converts old QR codes to the new format, in an hacky, but simple
way, see #6518 for more details and for code snippet
then QR code change is esp. bad as ppl will have different versions for
some days at least, weakening overall UX, esp. of first-time-users that
may come to delta because of praised, seamless multidevice ... :)
i tested in https://github.com/deltachat/deltachat-ios/pull/2595 that
this actually fixes the problem, and there is no deeper issue with
changed chashes or so - seemed not to be the case, at least, with this
hack, core accepts QR codes from the released 1.52-and-before series
this hack gives user time to update, it can be removed after some months
(we can also remove the old BACKUP qr code alltogether then)
we should still not wait too long with the PR as there are already
versions out with the "new/bad" QR code (and growing, as new iOS
installations will get the new format, one cannot revert a version, only
pause rollout)

This change adds a test and updates mailparse from 0.15.0 to 0.16.0.
mailparse 0.16.0 includes a fix for the bug
that resulted in CRLF being included at the end of the body.
Workaround for the bug in the `pk_validate` function is also removed.
APNS tokens never expire unless
the user uninstalls the application.
Because of this in most cases
the token remains valid forever
and chatmail server never removes the token
even if it is unencrypted
or the user has removed Delta Chat profile
from the device but not the whole application.
We want to modify chatmail servers
to remember the last time the token was stored
and remove them after some time.
Before we do this, we need to modify
the client to store the device token
each time so the server knows which tokens are used
and can update their timestamps.
QR code format changed because `NodeAddr` serialization
changed between iroh 0.29.0 and iroh 0.30.0.
We have already released iroh 0.30.0,
so the test at least makes change we don't break compatibility again.
There was a bug that file extensions were removed when recoding an
avatar. The problem was that `recode_avatar` used `name` to check for
the extension, but some functions passed an empty string.
There even were two tests from before the decision to keep the
extensions that tested for the faulty behavior.
These were the last places in the `deltachat` crate where files were
stored without deduplication. The CFFI python bindings are the last
thing that's still missing.
Deduplicate:
- In the REPL
- In `store_from_base64()`, which writes avatars received in headers
- In a few tests
- The saved messages, broadcast, device, archive icons
- The autocrypt setup message
1-2 more PRs, and we can get rid of `BlobObject::create`,
`sanitise_name()`, and some others
When receiving messages, blobs will be deduplicated with the new
function `create_and_deduplicate_from_bytes()`. For sending files, this
adds a new function `set_file_and_deduplicate()` instead of
deduplicating by default.
This is for
https://github.com/deltachat/deltachat-core-rust/issues/6265; read the
issue description there for more details.
TODO:
- [x] Set files as read-only
- [x] Don't do a write when the file is already identical
- [x] The first 32 chars or so of the 64-character hash are enough. I
calculated that if 10b people (i.e. all of humanity) use DC, and each of
them has 200k distinct blob files (I have 4k in my day-to-day account),
and we used 20 chars, then the expected value for the number of name
collisions would be ~0.0002 (and the probability that there is a least
one name collision is lower than that) [^1]. I added 12 more characters
to be on the super safe side, but this wouldn't be necessary and I could
also make it 20 instead of 32.
- Not 100% sure whether that's necessary at all - it would mainly be
necessary if we might hit a length limit on some file systems (the
blobdir is usually sth like
`accounts/2ff9fc096d2f46b6832b24a1ed99c0d6/dc.db-blobs` (53 chars), plus
64 chars for the filename would be 117).
- [x] "touch" the files to prevent them from being deleted
- [x] TODOs in the code
For later PRs:
- Replace `BlobObject::create(…)` with
`BlobObject::create_and_deduplicate(…)` in order to deduplicate
everytime core creates a file
- Modify JsonRPC to deduplicate blob files
- Possibly rename BlobObject.name to BlobObject.file in order to prevent
confusion (because `name` usually means "user-visible-name", not "name
of the file on disk").

https://www.geogebra.org/calculator, both of which came to the same
result

- This [is said to lead improve compilation
speed](https://matklad.github.io/2021/02/27/delete-cargo-integration-tests.html#Assorted-Tricks)
- When grepping for a function invocation, this makes it easy to see whether it's from a test or "real" code
- We're calling the files e.g. `chat_tests.rs` instead of `tests.rs` for the same reason why we moved `imap/mod.rs` to `imap.rs`: Otherwise, your editor always shows you that you're in the file `tests.rs` and you don't know which one.
This is only moving mimeparser and chat tests, because these were the
biggest files; we can move more files in subsequent PRs if we like it.
Fix https://github.com/deltachat/deltachat-core-rust/issues/6433
I at first only wanted to do it any outgoing messages, but @link2xt was
concerned that this may accidentally enable bcc_self, e.g. in the
following case:
- you send out a message
- it's deleted, e.g. via ephemeral messages
- Someone forwards this outgoing message to you again, e.g. via a
mailing list.
If we create an unpromoted group,
add a member there and then remove it
before we promote a group, there is no need to
add such member to the list of past members
and send the address of this member to the group
when it is promoted.
> _took quite some time until i found the time to finish this PR and to
find a time window that does not disturb other developments too much,
but here we are:_
this PR enables UI to improve "Saved messages" hugely, bringing it on
WhatsApp's "Starred Messages" or Telegram's "Saved Messages" level. with
this PR, UIs can add the following functionality with few effort ([~100
loc on iOS](https://github.com/deltachat/deltachat-ios/pull/2527)):
- add a "Save" button in the messages context menu, allowing to save a
message
- show directly in the chat if a message was saved, eg. by a little star
★
- in "Saved Messages", show the message in its context - so with author,
avatar, date and keep incoming/outgoing state
- in "Saved Messages", a button to go to the original message can be
added
- if the original message was deleted, one can still go to the original
chat
these features were often requested, in the forum, but also in many
one-to-one discussions, recently at the global gathering.
moreover, in contrast to the old method with "forward to saved", no
traffic is wasted - the messages are saved locally, and only a small
sync messages is sent around
this is how it looks out on iOS:
<img width="260" alt="Screenshot 2025-01-17 at 00 02 51"
src="https://github.com/user-attachments/assets/902741b6-167f-4af1-9f9a-bd0439dd20d0"

/>
technically, still a copy is done from the original message (with
already now deduplicated blobs), so that things work nicely with
deletion modes; eg. you can save an important message and preserve it
from deletion that way.
jsonrpc can be done in a subsequent PR, i was implementing the UI on iOS
where that was not needed (and most API were part of message object that
is not in use in jsonrpc atm)
@hpk42 the forward issue we discussed earller that day is already solved
(first implementation did not had an explict save_msgs() but was using
forward_msgs(SELF) as saving - with the disadvantage that forwarding to
SELF is not working, eg. if one wants the old behaviour) acutally, that
made the PR a lot nicer, as now very few existing code is changed
<details>
<summary>previous considerations and abandoned things</summary>
while working on this PR, there was also the idea to just set a flag
“starred” in the message table and not copy anything. however, while
tempting, that would result in more complexity, questions and drawbacks
in UI:
- delete-message, delete-chat, auto-deletion, clear-chat would raise
questions - what do do with the “Starred”? having a copy in “Saved
Messages” does not raise this question
- newly saved messages appear naturally as “new” in “Saved Messages”,
simply setting a flag would show them somewhere in between - unless we
do additional effort
- “Saved Messages” already has its place in the UI - and allows to
_directly_ save things there as well - not easily doable with “starring”
- one would need to re-do many things that already exist in “Saved
Messages”, at least in core
- one idea to solve some of the issues could be to have “Starred” as
well as “Saved Messages” - however, that would irritate user, one would
remember exactly what was done with a message, and understand the fine
differences
whatsapp does this “starred”, btw, so when original is deleted, starred
is deleted as well. Telegram does things similar to us, Signal does
nothing. Whatsapp has a per-chat view for starred messages - if needed,
we could do sth. like that as well, however, let’s first see how far the
“all view” goes (in contrast to whatsapp, we have profiles for
separation as well)
for the wording: “saving” is what we’re doing here, this is much more on
point as “starring” - which is more the idea of a “bookmark”, and i
think, whatsapp uses this wording to not raise false expectations
(still, i know of ppl that were quite upset that a “starred” message was
deleted when eg. the chat was cleared to save some memory)
wrt webxdc app updates: options that come into mind were: _empty_ (as
now), _snapshot_ (copy all updates) or _shortcut_ (always open
original). i am not sure what the best solution is, the easiest was
_empty_, so i went for that, as it is (a) obvious, and what is already
done with forwarding and (b) the original is easy to open now (in
contrast to forwarding).
so, might totally be that we need or want to tweak things here, but i
would leave that outside the first iteration, things are not worsened in
that area
wrt reactions: as things are detached, similar to webxdc updates, we do
not not to show the original reactions - that way, one can use reactions
for private markers (telegram is selling that feature :)
to the icon: a disk or a bookmark might be other options, but the star
is nicer and also know from other apps - and anyways a but vague UX
wise. so i think, it is fine
finally, known issue is that if a message was saved that does not exist
on another device, it does not get there. i think, that issue is a weak
one, and can be ignored mostly, most times, user will save messages soon
after receiving, and if on some devices auto-deletion is done, it is
maybe not even expected to have suddenly another copy there
</details>
EDIT: once this is merged, detailed issues about what to do should be
filed for android/desktop (however, they do not have urgency to adapt,
things will continue working as is)

This partially restores the fix from c9cf2b7f2e
that was removed during the addition of new group consistency at de63527d94
but only for "Member added" messages.
Multiple "Member added" messages happen
when the same QR code is processed multiple times
by multiple devices.
Some migrations change the `config` table, but they don't update the
cache. While this wasn't the cause for
https://github.com/deltachat/deltachat-core-rust/issues/6432, it might
have caused a similar bug, so, let's clear the config cache after every
migration.
Users report that in a setup with Android (1.50.4 from F-Droid) and Desktop (1.48.0 x86_64 .deb
release) and chatmail account `bcc_self` was reverted to 0 on Android, resulting in messages sent
from Android not appearing on Desktop. This might happen because of the bug in migration #127, it
doesn't handle `delete_server_after` > 1. Existing chatmail configurations having
`delete_server_after` != 1 ("delete at once") should get `bcc_self` enabled, they may be multidevice
configurations:
- Before migration #127, `delete_server_after` was set to 0 upon a backup export, but
then `bcc_self` is enabled instead (whose default is changed to 0 for chatmail).
- The user might set `delete_server_after` to a value other than 0 or 1 when that was
possible in UIs.
So let's add another migration fixing this. But still don't check `is_chatmail` for simplicity.
Using `repeat_vars()` to generate SQL statements led to some of them having more than
`SQLITE_MAX_VARIABLE_NUMBER` parameters and thus failing, so let's get rid of this pattern. But
let's not optimise for now and just repeat executing an SQL statement in a loop, all the places
where `repeat_vars()` is used seem not performance-critical and containing functions execute other
SQL statements in loops. If needed, performance can be improved by preparing a statement and
executing it in a loop. An exception is `lookup_chat_or_create_adhoc_group()` where `repeat_vars()`
can't be replaced with a query loop, there we need to replace the `SELECT` query with a read
transaction creating a temporary table which is used to perform the SELECT query then.
Before, `Chat::why_cant_send()` just returned `CantSendReason` after the first unsuccessful check
allowing to handle the result and finally send the message if the condition is acceptable in which
case the remaining checks are not done. This didn't result in any bugs, but to make the code more
robust let's add a functional parameter to filter failed checks without early return.
This implements new group consistency algorithm described in
<https://github.com/deltachat/deltachat-core-rust/issues/6401>
New `Chat-Group-Member-Timestamps` header is added
to send timestamps of member additions and removals.
Member is part of the chat if its addition timestamp
is greater or equal to the removal timestamp.
Python 3.7 is not supported on GitHub Actions ubuntu-latest runner:
https://github.com/actions/setup-python/issues/962
Python 3.7 has reached EOL more than 1 year ago anyway,
so not worth the effort supporting it.
This test keeps failing on macOS CI,
capturing events like `DC_EVENT_ACCOUNTS_ITEM_CHANGED`
before FailPlugin is setup.
These CI runners likely get less resources
because there is a limited number of them,
and this triggers this race condition.
Race is fixed by setting up fail plugin
before starting to capture events.
Currently Delta Chat puts self address in the To field
to avoid the To field being empty.
There is a plan to put empty `hidden-recipients`
group there, this fix prepares the receiver for such messages.
New Delta Chat is going to send self-sent messages
with undisclosed recipients instead of placing self into the `To` field.
To avoid assigning broadcast list messages to Saved Messages chat,
we should check the mailing list headers
before attempting to assign to Saved Messages.
First of all, chatmail servers normally forbid to send unencrypted mail, so if we know the peer's
key, we should encrypt to it. Chatmail setups have `E2eeEnabled=1` by default and this isn't
possible to change in UIs, so this change fixes the chatmail case. Additionally, for chatmail, if a
peer has `EncryptPreference::Reset`, let's handle it as `EncryptPreference::NoPreference` for the
reason above. Still, if `E2eeEnabled` is 0 for a chatmail setup somehow, e.g. the user set it via
environment, let's assume that the user knows what they do and ignore `IsChatmail` flag.
NB:
- If we don't know the peer's key, we should try to send an unencrypted message as before for a
chatmail setup.
- This change doesn't remove the "majority rule", but now the majority with
`EncryptPreference::NoPreference` can't disable encryption if the local preference is `Mutual`. To
disable encryption, some peer should have a missing peerstate or, for the non-chatmail case, the
majority should have `EncryptPreference::Reset`.
Change `BccSelf` default to 0 for chatmail configurations and enable it upon a backup export. As for
`DeleteServerAfter` who was set to 0 upon a backup export before, make its default dependent on
`BccSelf` for chatmail. We don't need `BccSelf` for chatmail by default because we assume
single-device use. Also `BccSelf` is needed for "classic" email accounts even if `DeleteServerAfter`
is set to "immediately" to detect that a message was sent if SMTP server is slow to respond and
connection is lost before receiving the status line which isn't a problem for chatmail servers.
Even if UIs don't call `Message::force_sticker()`, they don't want conversions of `Sticker` to
`Image` if it's obviously not an image, particularly, has non-image extension. Also UIs don't want
conversions of `Sticker` to anything other than `Image`, so let's keep the `Sticker` viewtype in
this case.
In multi-device case `vg-request-with-auth` left on IMAP may result in situation when Bob joins the
group, then leaves it, then second Alice device comes online and processes `vg-request-with-auth`
again and adds Bob back. So we should IMAP-delete `vg-request-with-auth`. Another device will know
the Bob's key from Autocrypt-Gossip. It's not a problem if Alice loses state (restores from an old
backup) or goes offline for long before sending `vg-member-added`, anyway it may not be delivered by
the server, rather Bob should retry sending SecureJoin messages as he is a part which wants to join,
so let's not solve this for now.
Add a `create` param to `select_with_uidvalidity()` instead of always trying to create the folder
and return `Ok(false)` from it if the folder doesn't exist and shouldn't be created, and handle this
in `store_seen_flags_on_imap()` by just removing "jobs" from the `imap_markseen` table. Also don't
create the folder in other code paths where it's not necessary.
This is to avoid revalidating HTTP cache too frequently (and have many parallel revalidation tasks)
if revalidation fails or the HTTP request takes some time. The stale period >= 1 hour, so 1 more
minute won't be a problem.
It was called from `receive_imf` when an outgoing message is received. But
`Imap::fetch_new_messages()` already calls `chat::mark_old_messages_as_noticed()` which does the job
better (per-message).
SQL statements fail if the number of variables
exceeds `SQLITE_LIMIT_VARIABLE_NUMBER`.
Remaining repeat_vars() calls are difficult to replace
and use arrays passed from the UI,
e.g. forwarded message IDs or marked as seen IDs.
UIs may want to display smth like "Transferring..." after "Establishing connection between
devices..." on nonzero progress. Before, progress on the receiver side was starting with 2 after
receiving enough data.
It only contained proxy
that some users ran in Termux
to look at IMAP traffic.
The same can be achieved with `socat`, e.g.:
socat -v TCP-LISTEN:9999,bind=127.0.0.1 OPENSSL:nine.testrun.org:993
This fixes the HTML display of messages containing forwarded messages. Before, forwarded messages
weren't rendered in HTML and if a forwarded message is long and therefore truncated in the chat, it
could only be seen in the "Message Info". In #4462 it was suggested to display "Show Full
Message..." for each truncated message part and save to `msgs.mime_headers` only the corresponding
part, but this is a quite huge change and refactoring and also it may be good that currently we save
the full message structure to `msgs.mime_headers`, so i'd suggest not to change this for now.
Otherwise the "Show Full Message..." button appears somewhere in the middle of the multipart
message, e.g. after a text in the first message bubble, but before a text in the second
bubble. Moreover, if the second/n-th bubble's text is shortened (ends with "[...]"), the user should
scroll up to click on "Show Full Message..." which doesn't look reasonable. Scrolling down looks
more acceptable (e.g. if the first bubble's text is shortened in a multipart message).
I'd even suggest to show somehow that message bubbles belong to the same multipart message, e.g. add
"[↵]" to the text of all bubbles except the last one, but let's discuss this first.
without the prefix,
it looks as if it is part of the Message-ID,
esp. if Message-ID is longer,
a break on different delimiters may look exactly the same.
see #6329 for some screenshots that initially confused me :)
A user reported to me that after they left a group, they were implicitly readded, but there's no any
readdition message, so currently it looks in the chat like leaving it has no effect, just new
messages continue to arrive. The readdition probably happened because some member didn't receive the
user's self-removal message, anyway, at least there must be a message that the user is readded, even
if it isn't known by whom.
A NDN may arrive days after the message is sent when it's already impossible to tell which message
wasn't delivered looking at the "Failed to send" info message, so it only clutters the chat and
makes the user think they tried to send some message recently which isn't true. Moreover, the info
message duplicates the info already displayed in the error message behind the exclamation mark and
info messages do not point to the message that is failed to be sent.
Moreover it works rarely because `mimeparser.rs` only parses recipients from `x-failed-recipients`,
so it likely only works for Gmail. Postfix does not add this `X-Failed-Recipients` header. Let's
remove this parsing too. Thanks to @link2xt for pointing this out.
This PR:
- Moves the note about the false positive to the end of the test output,
where it is more likely to be noticed
- Also notes in test_modify_chat_disordered() and
test_setup_contact_*(), in addition to the existing note in
test_was_seen_recently()
This fixes HTML display of truncated (long) sent messages ("Show full message" in UIs). Before,
incorrect HTML was stored (with missing line breaks etc.) for them. Now stored plaintext is
formatted to HTML upon calling `MsgId::get_html()` and this results in the same HTML as on a
receiver side.
Also cleaned up test_connectivity()
which tested that state does not flicker to WORKING
when there are no messages to be fetched.
The state is expected to flicker to WORKING
when checking for new messages,
so the tests were outdated since
change 3b0b2379b8
The benchmark function (e.g. `recv_all_emails()`) is executed multiple
times on the same context. During the second iteration, all the emails
were already in the database, so, receiving them again failed.
This PR fixes that by passing in a second `iteration` counter that is
different for every invocation of the benchmark function.
This better reflects that this state means
we just connected and there may me work to do.
This state is converted to DC_CONNECTIVITY_WORKING
instead of DC_CONNECTIVITY_CONNECTED state now.
Before this change when IMAP connected
to the server, it switched
from DC_CONNECTIVITY_NOT_CONNECTED
to DC_CONNECTIVITY_CONNECTING,
then to DC_CONNECTIVITY_CONNECTED (actually preparing)
then to DC_CONNECTIVITY_WORKING
and then to DC_CONNECTIVITY_CONNECTED again (actually idle).
On fast connections this resulted in flickering "Connected"
string in the status bar right before "Updating..."
and on slow connections this "Connected" state
before "Updating..." lasted for a while
leaving the user to wonder if there are no new messages
or if Delta Chat will still switch to "Updating..."
before going into "Connected" state again.
Already apply rust beta (1.84) clippy suggestions now, before they let
CI fail in 6 weeks.
The newly used functions are available since 1.70, our MSRV is 1.77, so
we can use them.
A sync message for accepting or blocking a 1:1 chat may arrive before the first message from the
contact, when it does not exist yet. This frequently happens in non-chatmail accounts that have
moving to the DeltaChat folder disabled because Delta Chat unconditionally uploads sync messages to
the DeltaChat folder. Let's create a hidden contact in this case and a 1:1 chat for it.
this partly reverts experimental #3516
that allowed any .xdc sent to "Saved Messages" to request internet.
this helped on pushing map integration forward.
meanwhile, however, we have that map integration (#5461 and #5678),
that implies `info.internet_access` being set.
experimental `manifest.request_internet_access` is no longer needed therefore.
future will tell, if we revive the option at some point or
go for more intrations ('sending' is discussed often :) -
but currently it is not needed.
with this PR, when an `.xdc` with `request_integration = map` in the
manifest is added to the "Saved Messages" chat, it is used _locally_ as
an replacement for the shipped maps.xdc (other devices will see the
`.xdc` but not use it)
this allows easy development and adapting the map to use services that
work better in some area.
there are lots of known discussions and ideas about adding more barriers
of safety. however, after internal discussions, we decided to move
forward and also to allow internet, if requested by an integration (as
discussed at
https://github.com/deltachat/deltachat-core-rust/pull/3516).
the gist is to ease development and to make users who want to adapt,
actionable _now_, without making things too hard and adding too high
barriers or stressing our own resources/power too much.
note, that things are still experimental and will be the next time -
without the corresponding switch being enabled, nothing will work at
all, so we can be quite relaxed here :)
for android/ios, things will work directly. for desktop, allow_internet
needs to be accepted unconditionally from core. for the future, we might
add a question before using an integration and/or add signing. or sth.
completely different - but for now, the thing is to get started.
nb: "integration" field in the webxdc-info is experimental as well and
should not be used in UIs at all currently, it may vanish again and is
there mainly for simplicity of the code; therefore, no need to document
that.
successor of https://github.com/deltachat/deltachat-core-rust/pull/5461
this is how it looks like currently - again, please note that all that
is an experiment!

... when going out of experimental, there are loots of ideas, eg.
changing "Start" to "integrate"
following `RELEASE.md`, after merging, the following is needed:
6. Tag the release: `git tag --annotate v1.151.2`.
7. Push the release tag: `git push origin v1.151.2`.
8. Create a GitHub release: `gh release create v1.151.2 --notes ''`.
this PR adds the `href` from `update.href` to the IncomingWebxdcNotify
event (DC_EVENT_INCOMING_WEBXDC_NOTIFY in cffi)
purpose is to add a "Start" button to the notifications that allow
starting the app immediately with the given href
using long options make things less mystical, it is clearer what
happens.
(apart from that i also disallowed `git -a` on my machine in general, as
`git commit -a` is considered harmful. as my approach to disallow that
is a bit greedy and disallows `-a` just for any git commands, this is
the only place where i regularly struggle :)
Text parts are using quoted-printable encoding
which takes care of wrapping long lines,
so using format=flowed is unnecessary.
This improves compatibility with receivers
which do not support format=flowed.
Receiving format=flowed messages is still possible, receiver side of
Delta Chat is unchanged.

add `update.href` property option to update objects send via
`Context::send_webxdc_status_update()`.
when set together with `update.info`,
UI can implement the info message as a link that is passed to the webxdc
via `window.location.href`.
for that purpose, UI will read the link back from
`Message::get_webxdc_href()`.
Practically,
this allows e.g. an calendar.xdc
to emits clickable update messages
opening the calendar at the correct date.
closes#6219
documentation at https://github.com/webxdc/website/pull/90
it may be handy for an xdc to have only one list of all adresses, or
there may just be bugs.
in any case, do not notify SELF, e.g. in a multi-device setup; we're
also not doing this for other messages.
this is also a preparation for having an option to notify ALL.
I found the old documentation rather hard to understand. The new doc
string:
- uses whole sentences, leaving less space for misinterpretation
- explicitly mentions that it can happen that there is no
webxdc-info-message
- is clearly structured using bullet points.
this PR adds support for the property `update.notify` to notify about
changes in `update.info` or `update.summary`. the property can be set to
an array of addresses [^1]
core emits then the event `IncomingWebxdcNotify`, resulting in all UIs
to display a system notification, maybe even via PUSH.
for using the existing `update.info` and `update.summary`: the message
is no secret and should be visible to all group members as usual, to not
break the UX of having same group messages on all devices of all users -
as known already from the normal messages.
also, that way, there is no question what happens if user have disabled
notifications as the change is presented in the chat as well

this PR adds the address to be used by the UI for
`window.webxdc.selfAddr` to webxdc-info. UIs need to be changed
accordingly and must not use configured_addr any longer.
the address is created by sha256(private-key + rfc724_mid) , which
results in different addresses for each webxdc, without the option to
find out the real address of the user.
this also returns the same address for a multi-device-setup - sending
totally random self address around might be an alternative, however
would require connectivity (both devices may be offline on first start).
for existing app, after the change, there will be a new user, resulting
eg. in a new highscore, otherwise, things should be mostly fine. this
assumption is also important as we might change the thing another time
when it comes to multi-transport.
ftr, addresses look like
`0f187e3f420748b03e3da76543e9a84ecff822687ce7e94f250c04c7c50398bc` now
when this is merged, we need to adapt #6230 and file issues for all UI
to use `info.selfAddr`
closes#6216
`receive_imf() is only used in tests and the REPL, which enables the
"internals" feature. This PR marks it as such, so that it's clear not
only from the comment that this function is not used for anything else.
If a message partially downloaded before is already IMAP-seen upon a full download, it should be
updated to `InSeen`. OTOH if it's not IMAP-seen, but already `InNoticed` locally, its state should
be preserved. So we take the maximum of two states.
This fixes sending MDNs for big messages when they are downloaded and really seen. Otherwise MDNs
are not sent for big encrypted messages because they "don't want MDN" until downloaded.
Add a test on what happens currently when apps call `markseen_msgs()` for not downloaded encrypted
messages. Such messages are marked as seen, but MDNs aren't sent for them. Also currently when such
a message is downloaded, it remains `InSeen` despite the full content hasn't yet been seen by the
user.
As discussed in #5467 we want to use `i.delta.chat` in QR codes in favor
of `OPENPGP4FPR:` scheme. This PR does the replacement in
`get_securejoin_qr` which is used in `get_securejoin_qr_svg`.
close#5467
This is needed for iOS (https://github.com/deltachat/deltachat-ios/pull/2393), see comment in the code. An alternative would be
to add an API `invalidate_config_cache()` or to do nothing and just
assume that things will be fine.
There is a change in behavior for the case
when name is the same as the suffix
(`name_len` == `namespc_len`),
but normally `files_in_use` should not contain empty filenames.
The message may be deleted while chatlist item is loading.
In this case displaying "No messages" is better than failing.
Ideally loading of the chatlist item
should happen in 1 database transaction and
always return some message if chat is not empty,
but this requires large refactoring.
this PR changes `DC_CERTCK_ACCEPT_*` to the same values in cffi as rust
does. and regards the same values as deprecated afterwards
there is some confusion about what is deprecated and what not, see
https://github.com/deltachat/deltachat-android/issues/3408
iOS needs to be adapted as it was following the docs in the CFFI before,
same desktop. both need to be graceful on reading and strict on writing.
~~**this PR is considered harmful,** so we should not merge that in
during 1.48 release, there is no urgency, things are fine (wondering if
it isn't even worth the effort, however, having different values and
deprecations is a call for trouble in the future ...)~~

due to async processing,
it may happen getConnectivityHtml() is called from UI before startIO() is actually called.
eg. on iOS, we may delay startIo() if another process is still processing a PUSH notification -
when during this time, the connectivity view is opened,
it is weird if a big error "CONTACT THE DEVELOPERS!11!!!" is shown :)
also, there is not really a function is_connected(),
for $reasons, as this turned out to be flacky,
so it is not even easy to check the state before calling getConnectivityHtml()
it is not worth in doing too much special,
we are talking about rare situaton,
also, the connectivity view gets updated some moments later.
Before I was getting
```

After this update it is fixed.
80 characters are a bit limited in practise ...

... already breaks the limit. it is good to allow up to 40 additional characters

allowing any length, however, may catch too much,
as the line could also be a normal paragraph with important content,
so 120 characters seems reasonable.
the idea of adding more complexity here would probably lead only to, well more complexity -
things can anyways go wrong -
and, we have the "show full message..." button for exactly that purpose,
so that the user can access everything as original.
so, if things go wrong sometimes,
this is expected and fine.
There were many cases in which "member added/removed" messages were added to chats even if they
actually do nothing because a member is already added or removed. But primarily this fixes a
scenario when Alice has several devices and shares an invite link somewhere, and both their devices
handle the SecureJoin and issue `ChatGroupMemberAdded` messages so all other members see a
duplicated group member addition.
This change adds support for receiving
Autocrypt header in the protected part of encrypted message.
Autocrypt header is now also allowed in mailing lists.
Previously Autocrypt header was rejected when
List-Post header was present,
but the check for the address being equal to the From: address
is sufficient.
New experimental `protect_autocrypt` config is disabled
by default because Delta Chat with reception
support should be released first on all platforms.
Over the past years, it happend two times that a user came to me worried
about a false-positive "Cannot login as ***. Please check if the e-mail
address and the password are correct." message.
I'm not sure why this happened, but this PR makes the logic for
showing this notification stricter:
- Before: The notification is shown if connection fails two times in a
row, and the second error contains the word "authentication".
- Now: The notification is shown if the connection fails two times in a
row, and _both_ error messages contain the word "authentication".
The second commit just renames `login_failed_once` to
`authentication_failed_once` in order to reflect this change.
Delta Chat for Android does not support Android 4 anymore,
so there is no reason to keep using unsupported NDK.
r27 is the latest LTS version of Android NDK.
Tested:
- `nix build .#deltachat-rpc-server-arm64-v8a-android`
- `nix build .#deltachat-rpc-server-armv6l-linux`
`nix build .#deltachat-rpc-server-x86_64-android`
and
`nix build .#deltachat-rpc-server-x86-android`
still fail, but we do not build it in CI.
Explicit check for `-----BEGIN PGP MESSAGE-----` is unnecessary
and not sufficient to ensure that the message is valid.
We have already checked the MIME type,
so ASCII-armored OpenPGP message should be inside.
If it's not, decryption will fail anyway.

Concat error messages when receiving new ndns.
This PR adds a newline followed by the new NDN error to the error text.
Maybe we should use something more prominent like
```
-----------------------------------------------------------------------
```
or more newlines, but I'm not sure. This maybe has to be tested on a
real device to see what works best.
3f9242a saves name from all QR codes to `name` (i.e. manually edited name), but for SecureJoin QR
codes the name should be saved to `authname` because such QR codes are generated by the
inviter. Other QR codes may be generated locally and not only by Delta Chat, so the name from them
mustn't go to `authname` and be revealed to the network or other contacts.
If the number of retries for message is exceeded,
do not fail when marking it as failed if the message does not exist.
Otherwise we may never delete the message from SMTP queue
because corresponding msg_id is not valid anymore.
The server should decode the URL and according to RFC 3986
query parameters may or may not be URL-encoded,
but at some servers don't decode the dot correctly.
`@` is decoded correctly by autoconfig.murena.io
This may indicate that there was a new \Seen flag
that we don't want to skip.
Also don't drain unsolicited responses while scanning folders. Now we
only drain unsolicited responses right before IDLE and always redo the
whole fetch cycle if there have been some. Some message in the scanned
folder may not be fetched that would be previously fetched otherwise,
but it will be picked up on the next folder scan.
Just a small refactoring. Instead of rebinding res all the time just use
`and` and `and_then`how they are inteded to be used. Improves code
readability imo.
This adds a function to `Message`:
```rust
pub fn new_text(text: String) -> Self {
Message {
viewtype: Viewtype::Text,
text,
..Default::default()
}
}
```
I keep expecting that a function like this must exist and being
surprised that it doesn't.
Open question is whether it should be `pub` or `pub(crate)` - I made it
`pub` for now because it may be useful for others and we currently we
aren't thinking about the Rust API that much, anyway, but I can make it
`pub(crate)`, too (then it can't be used in deltachat-jsonrpc and
deltachat-repl).
I replaced some usages of Message::new(Viewtype::Text), but not all yet,
I'm going to do this in a follow-up, which will remove another around 65
LOC.
Right now, when there is an SMTP connection error, the connectivity view
will always show "Error: SMTP connection failure: SMTP failed to
connect".
Instead, I just used the same method that is used in imap connect()
already.
0a63083df7 (fix: Shorten message text in locally sent messages too)
sets `msgs.mime_modified` for long outgoing messages, but forgets to save full message text.
I.e. add the "Messages are guaranteed to be end-to-end encrypted from now on." message and mark the
chat as protected again because no user action is required in this case. There are a couple of
problems though:
- If the program crashes earlier than the protection is restored, the chat remains
protection-broken. But this problem already exists because `ChatId::set_protection()` is never
retried.
- If multiple old unverified messages are received, protection messages added in between don't
annihilate, so they clutter the chat.
Let's always set `Config::NotifyAboutWrongPw` before saving configuration, better if a wrong
password notification is shown once more than not shown at all. It shouldn't be a big problem
because reconfiguration is a manual action and isn't done frequently.
Also for the same reason reset `Config::NotifyAboutWrongPw` only after a successful addition of the
appropriate device message.
Otherwise it always fails with SQLITE_READONLY:
```
WARNING src/sql.rs:769: Failed to run incremental vacuum: attempt to write a readonly database: Error code 8: Attempt to write a readonly database.
```
this PR adds a function that can be used to create any QR code, in a raw
form.
this can be used to create add-contact as well as add-second-device QR
codes (eg. `dc_create_qr_svg(dc_get_securejoin_qr())`) - as well as for
other QR codes as proxies.
the disadvantage of the rich-formatted QR codes as created by
`dc_get_securejoin_qr_svg()` and `dc_backup_provider_get_qr_svg()` were:
- they do not look good and cannot interact with UI layout wise (but
also tapping eg. an address is not easily possible)
- esp. text really looks bad. even with
[some](e5dc8fe3d8)
[hacks](https://github.com/deltachat/deltachat-android/pull/2215) it
[stays buggy](https://github.com/deltachat/deltachat-ios/issues/2200);
the bugs mainly come from different SVG implementation, all need their
own quirks
- accessibility is probably bad as well
we thought that time, SVG is a great thing for QR codes, but apart from
basic geometrics, it is not.
so, we avoid text, this also means to avoid putting an avatar in the
middle of the QR code (we can put some generic symbol there, eg.
different ones for add-contact and add-second-device).
while this looks like a degradation, also other messengers use more raw
QR codes. also, we removed many data from the QR code anyway, eg. the
email address is no longer there. that time, sharing QR images was more
a thing, meanwhile we have invite links, that are much better for that
purpose.
in theory, we could also leave the SVG path completely and go for PNG -
which we did not that time as PNG and text looks bad, as the system font
is not easily usable :) but going for PNG would add further challenges
as passing binary data around, and also UI-implemtation-wise, that would
be a larger step. so, let's stay with SVG in a form we know is
compatible.
the old QR code functions are deprecated.
this PR allows setting a "private tag" for a profile, see
https://github.com/deltachat/deltachat-android/pull/3373 for a possible
UI.
currently, the core does not do anything with the tag (so, it could also
be a ui.-config option), however, this may change in the future - it
might bet synced, and become also otherwise useful in core. also, having
this in core is better documentation-wise, as otherwise each UI easily
does its own things :)
This adds "stale-while-revalidate" in-memory cache for DNS. Instead of
calling `tokio::net::lookup_host` we use previous result of
`tokio::net::lookup_host` immediately and spawn revalidation task in the
background. This way all lookups after the first successful one return
immediately.
Most of the time results returned by resolvers are the same anyway, but
with this cache we avoid waiting 60 second timeout if DNS request is
lost. Common reason result may be different is round-robin DNS load
balancing and switching from IPv4 to IPv6 network. For round-robin DNS
we don't break load balancing but simply use a different result, and for
IPv6 we anyway likely have a result in persistent cache and can use IPv4
otherwise.
Especially frequent should be the case when you send a message over SMTP
and SMTP connection is stale (older than 60 s), so we open a new one.
With this change new connection will be set up faster as you don't need
to wait for DNS resolution, so message will be sent faster.
rust-analyzer was showing warnings here because it is always also

become a hard error in the future
This is because when referring to a workspace dependency, it's not

the `vendored` feature was always enabled with no possibility to disable
it.
This PR restores the wanted behavior of enabling vendoring by default

It fixes `nix build .#python-docs` by not passing
`--no-default-features` when building deltachat with nix.

so the contact verification preserves. But the chat protection breaks because the old message is
sorted to the bottom as it mustn't be sorted over the protection info message (which is `InNoticed`
moreover). Would be nice to preserve the chat protection too e.g. add a "protection broken" message,
then the old message and then a new "protection enabled" message, but let's record the current
behaviour first.
To avoid reordering, wait for "member removed" message
to be received before sending "member added".
The test failed at least once
because email server may reorder the messages internally
while delivering.
Otherwise instead of "old address"
ac2 may receive "member added",
resulting in this failure:
```
> assert msg_in_1.text == msg_out.text
E AssertionError: assert 'Member Me (c...hat.computer.' == 'old address'
E - old address
E + Member Me (ci-hfpxxe@***) added by ci-8e7mkr@***.
```
This ensures we do not get stuck trying DNS resolver results
when we have a known to work IP address in the cache
and DNS resolver returns garbage
either because it is a captive portal
or if it maliciously wants to get us stuck
trying a long list of unresponsive IP addresses.
This also limits the number of results we try to 10 overall.
If there are more results, we will retry later
with new resolution results.
It is impossible to set no display name anyway
in Delta Chat Android at least
because we don't want email addresses
in the UI.
This test does not work with long domains
that may get wrapped, so better remove it
instead of trying to prevent wrapping of domains.
Received messages shouldn't mingle with just sent ones and appear somewhere in the middle of the
chat, so we go after the newest non fresh message.
But if a received outgoing message is older than some `InSeen` message, better sort the received
message purely by timestamp (this is an heuristic in order not to break the Gmail-like case
simulated by `verified_chats::test_old_message_4()`). We could place the received message just
before that `InSeen` message, but anyway the user may not notice it.
At least this fixes outgoing messages sorting for shared accounts where messages from other devices
should be sorted the same way as incoming ones.
Otherwise backups exported from the current core and imported in versions < 1.144.0 have QR codes
not working. The breaking change which removed the column is
5a6efdff44.
Before file extensions were also limited to 32 chars, but extra chars in the beginning were just cut
off, e.g. "file.with_lots_of_characters_behind_point_and_double_ending.tar.gz" was considered to
have an extension "d_point_and_double_ending.tar.gz". Better to take only "tar.gz" then.
Also don't include whitespace-containing parts in extensions. File extensions generally don't
contain whitespaces.
There is already code below that emits
progress 0 or 1000 depending on whether
configuration succeeded or failed.
Before this change cancelling resulted
in progress 0 emitted,
immediately followed by progress 1000.
Before this change progress bar only started
when database is already transferred.
Database is usually the largest file
in the whole transfer, so the transfer appears
to be stuck for the sender.
With this change progress bar
starts for backup export
as soon as connection is received
and counts bytes transferred over the connection
using AsyncWrite wrapper.
Similarly for backup import,
AsyncRead wrapper counts the bytes
received and emits progress events.
Instead of treating NULL type error
as absence of the row,
handle NULL values with SQL.
Previously we sometimes
accidentally treated a single column
being NULL as the lack of the whole row.
The "Cannot establish guaranteed end-to-end encryption with ..." info
message can have lots of causes, and it happened twice to us now that it
took us some time to figure out which one it is.
So, include some more detail in the info message by simply adding the
non-translated error message in parantheses.
If we want to put in some more effort for nicer error messages, we
could:
- Introduce one new translated string "Cannot establish guaranteed
end-to-end encryption with …. Cause: %2$s" or similar (and remove the
old stock string)
- And/Or: Introduce new translated strings for all the possible errors
- And/Or: Maybe reword it in order to account better for the case that
the chat already is marked as g-e2ee, or use a different wording
(because if the chat is marked as g-e2ee then it might be nice to notify
the user that something may have gone wrong, but it's still working,
just that maybe the other side doesn't have us verified now)
Info messages are added
at the beginning of unpromoted group chats
("Others will only see this group after you sent a first message."),
may be created by WebXDC etc.
They are not sent outside
and have local Message-ID that
is not known to other recipients
so they should be skipped when constructing
In-Reply-To and References.
Without this fix IMAP loop may get stuck
trying to download non-existing message over and over
like this:
```
src/imap.rs:372: Logging into IMAP server with LOGIN.
src/imap.rs:388: Successfully logged into IMAP server
src/scheduler.rs:361: Failed to download message Msg#3467: Message Msg#3467 does not exist.
src/scheduler.rs:418: Failed fetch_idle: Failed to download messages: Message Msg#3467 does not exist
```
The whole download operation fails
due to attempt to set the state of non-existing message
to "failed". Now download of the message
will "succeed" if the message does not exist
and we don't try to set its state.
HTTPS requests are used to fetch
remote images in HTML emails,
to fetch autoconfig XML,
to POST requests for `DCACCOUNT:` QR codes
to make OAuth 2 API requests
and to connect to HTTPS proxies.
Rustls is more aggressive than OpenSSL
in deprecating cryptographic algorithms
so we cannot use it for IMAP and SMTP
to avoid breaking compatibility,
but for HTTPS requests listed
above this should not result in problems.
As HTTPS requests use only strict TLS checks,
there is no `strict_tls` argument
in `wrap_rustls` function.
Rustls is already used by iroh,
so this change does not introduce new dependencies.
This should fix ad-hoc groups splitting when messages are fetched out of order from different
folders or otherwise reordered, or some messages are missing so that the messages reference chain is
broken, or a member was removed from the thread and readded later, etc. Even if this way two
different threads are merged, it looks acceptable, having many threads with the same name/subject
and members isn't a common use case.
Instead of generating 72 random bits
and reducing them to 66 bits of Base64 characters,
generate 144 bits (18 bytes)
which is exactly 24 Base64 characters.
This should still be accepted by existing
Delta Chat clients which expect group ID
to be between 11 and 32 characters.
Message-ID creation is also simplified
to not have `Mr.` prefix
and dot in between two IDs.
Now it is a single ID followed by `@localhost`.
Some outdated documentation comments
are removed, e.g. group messages
don't start with `Gr.` already.
The greeting is now always read manually,
even for STARTTLS connections,
so the errors returned on failure to read form the stream
are the same regardless of the connection type.
Why:
- With IMAP APPEND we can upload messages directly to the DeltaChat folder (for non-chatmail
accounts).
- We can set the `\Seen` flag immediately so that if the user has other MUA, it doesn't alert about
a new message if it's just a sync message (there were several such reports on the support
forum). Though this also isn't useful for chatmail.
- We don't need SMTP envelope and overall remove some overhead on processing sync messages.
If a displayname equals to the address, adding it looks excessive.
Moreover, it's not useful for Delta Chat receiving the message because
`sanitize_name_and_addr()` removes such a displayname anyway. Also now
at least DC Android requires specifying profile name, so there should be
a fallback for users having meaningful addresses to keep the old
behaviour when Core generates `From` w/o the profile name, and this
question has already appeared on the forum.
This reverts commit 1caf672904.
Otherwise public key signature is regenerated each time the key is
loaded and test `key::tests::test_load_self_existing` which loads the
key twice fails when two loads happen on different seconds.
Closes#5976
Groups promotion to other devices and QR code tokens synchronisation are not synchronised processes,
so there are reasons why a QR code token may arrive earlier than the first group message:
- We are going to upload sync messages via IMAP while group messages are sent by SMTP.
- If sync messages go to the mvbox, they can be fetched earlier than group messages from Inbox.
`chat::create_send_msg_jobs()` already handles `Config::BccSelf` as needed. The only exception is
Autocrypt setup messages. This change unifies the logic for the self-chat and groups only containing
`SELF`.
This makes possible to schedule one more sending of the message, the existing jobs are not
cancelled. Otherwise it's complicated to implement bots that resend messages when a new member joins
the group.
This change removes OAuth2 for Gmail
as Delta Chat does not have a working
client ID anymore.
Tests are adjusted to test against Yandex
and MX queries for OAuth2 are always disabled
because they were only used to detect Google Workspace.
This change introduces new config options
`proxy_enabled` and `proxy_url`
that replace `socks5_*`.
Tested with deltachat-repl
by starting it with
`cargo run --locked -p deltachat-repl -- deltachat-db` and running
```
> set proxy_enabled 1
> set proxy_url ss://...
> setqr dcaccount:https://chatmail.example.org/new
> configure
```
And also:
- Make it `pub(crate)`.
- Use it in `should_request_mdns()` as using `config_exists()` there isn't correct because the
latter doesn't look at environment.
I.e. treat `DeleteServerAfter == None` as "delete at once". But when a backup is exported, set
`DeleteServerAfter` to 0 so that the server decides when to delete messages, in order not to break
the multi-device case. Even if a backup is not aimed for deploying more devices, `DeleteServerAfter`
must be set to 0, otherwise the backup is half-useful because after a restoration the user wouldn't
see new messages deleted by the device after the backup was done. But if the user explicitly set
`DeleteServerAfter`, don't change it when exporting a backup. Anyway even for non-chatmail case the
app should warn the user before a backup export if they have `DeleteServerAfter` enabled.
Also do the same after a backup import. While this isn't reliable as we can crash in between, this
is a problem only for old backups, new backups already have `DeleteServerAfter` set if necessary.

There are providers in the provider database
that do not have servers specified.
For such providers default list should be tried
just like when configuring unknown providers.
Documentation comment says forward and backward verification is set,
but the code was not doing it.
`vc-contact-confirm` and `vg-member-added` messages
indicate that other device finished securejoin protocol
so we know Bob has our key marked as verified.
bcc_self has been enabled by default
since core version 1.95.0
by merging
PR <https://github.com/deltachat/deltachat-core-rust/pull/3612>.
However deltachat.h documentation
still incorrectly said that bcc_self is disabled by default.
This change replaces
usage of `reqwest` and `hyper-util`
with custom connection establishment code
so it is done in the same way
as for IMAP and SMTP connections.
This way we control HTTP, IMAP and SMTP
connection establishment
and schedule connection attempts
to resolved IP addresses
in the same way for all 3 protocols.
With current implementation
every time connection fails
we take the next delay from `delays` iterator.
In the worst case first 4 DNS results
immediately refuse connection
and we start fifth connection attempt
with 1 year timeout,
effectively continuing all remaining
connection attempts without concurrency.
With new implementation
new connection attempts are
added to `connection_attempt_set`
independently of connection failures
and after 10 seconds
we always end up with five
parallel connection attempts
as long as there are enough IP addresses.
Previously for each connection candidate (essentially host and port
pair) after resolving the host to a list of IPs Delta Chat iterated IP
addresses one by one. Now for IMAP and SMTP we try up to 5 IP addresses
in parallel. We start with one connection and add more connections
later. If some connection fails, e.g. we try to connect to IPv6 on IPv4
network and get "Network is unreachable" (ENETUNREACH) error, we replace
failed connection with another one immediately.

This ensures we don't add multiple Auto-Submitted headers
when bots send vg-request or vc-request messages.
The change fixes failing
receive_imf::tests::test_bot_accepts_another_group_after_qr_scan
test.
This fixes the bug that sometimes made QR scans fail.
The problem was:
When sorting headers into unprotected/hidden/protected, the From: header
was added twice for all messages: Once into unprotected_headers and once
into protected_headers. For messages that are `is_encrypted && verified
|| is_securejoin_message`, the display name is removed before pushing it
into unprotected_headers.
Later, duplicate headers are removed from unprotected_headers right
before prepending unprotected_headers to the message. But since the
unencrypted From: header got modified a bit when removing the display
name, it's not exactly the same anymore, so it's not removed from
unprotected_headers and consequently added again.
I.e. to all messages except "v{c,g}-request" as they sent out on a QR code scanning which is a
manual action and "vg-member-added" as formally this message is auto-submitted, but the member
addition is a result of an explicit user action. Otherwise it would be strange to have the
Auto-Submitted header in "member-added" messages of verified groups only.
Before the fix HTTP client
had no connection timeout,
so it only had a chance
to test one IPv6 and one IPv4
address if the first addresses timed out.
Now it can test at least 4 addresses
of each family and more if some addresses
refuse connection rather than time out.
Otherwise if DNS server returns incorrect results,
we may never try preloaded DNS results.
For example, we may get our first results
from a captive portal.
To test, add `127.0.0.1 example.org`
and try to create an account.
Without this change we only try 127.0.0.1 and fail.
With this change preloaded DNS results are tried as well.
this PR adds the type DC_QR_SOCKS5_PROXY to `dc_check_qr()` for
**supporting telegram proxy QR codes**. if returned, the UI should ask
the user if they want to us the proxy and call
`dc_set_config_from_qr();` afterwards (plus maybe `dc_configure()`).
idea is to improve our proxy story, follow ups may be:
- in UI, - move proxy out of "Account & Password", as a **separate
"Proxy Activity"** (it should stay in "Advanced" for now, however, below
"Server", which might be moved up)
- allow **opening the "Proxy Activity" from the welcome screens**
three-dot-menu (that would also solve a long standing issue that
entering the email address bypasses the proxy
- show proxy usage in the "Connectivity View" and/or add an **icon** to
the main chatlist screen (beside three-dot menu) in case some proxy is
in use; tapping this icon will open the "Proxy Activity"
- the the new "Proxy Activity", add a **share / show proxy QR code**
button. that would generate invite links in the form
`https://i.delta.chat/socks#...` - so that tapping then opens the app.
support for these links need to be added to core then.
- handle a list of proxies in core, offer selection in UI. the list
could be one for all profiles and could be filled eg. by normal invite
links or other channels

Fix a typo in the config name
(by using `Config::` to avoid it)
and make sure we don't panic on unknown values.
Also test that we don't panic on unknown
`configured_imap_certificate_checks` values.
Apparently some providers fail TLS connection
with "no_application_protocol" alert
even when requesting "imap" protocol for IMAP connection
and "smtp" protocol for SMTP connection.
Fixes <https://github.com/deltachat/deltachat-core-rust/issues/5892>.
configured_imap_certificate_checks=0 means
accept invalid certificates unless provider database
says otherwise or SOCKS5 is enabled.
It should not be saved into the database anymore.
This bug was introduced in
<https://github.com/deltachat/deltachat-core-rust/pull/5854>
(commit 6b4532a08e)
and affects released core 1.142.4, 1.142.5 and 1.142.6.
Fix reverts faulty fix from
<https://github.com/deltachat/deltachat-core-rust/pull/5886>
(commit a268946f8d)
which changed the way configured_imap_certificate_checks=0
is interpreted and introduced problems
for existing setups with configured_imap_certificate_checks=0:
<https://github.com/deltachat/deltachat-core-rust/issues/5889>.
Existing test from previous fix is not reverted
and still applies.
Regression test is added to check that
configured_imap_certificate_checks
is not "0" for new accounts.
If user has not set any settings manually
and provider is not configured,
default to strict TLS checks.
Bug was introduced in
<https://github.com/deltachat/deltachat-core-rust/pull/5854>
(commit 6b4532a08e)
and affects released core 1.142.4 and 1.142.5.
The problem only affects accounts configured
using these core versions with provider
not in the provider database or when using advanced settings.
`imap::Session::store_seen_flags_on_imap()` handles messages from multiple folders, so not being
able to select one folder mustn't fail the whole function.
`cargo install` ignores lockfile by default.
Without lockfile current build fails
due to iroh-net 0.21.0 depending on `derive_more` 1.0.0-beta.6
but failing to compile with `derive_more` 1.0.0.-beta.7.
This particular error will be fixed by upgrading to iroh 0.22.0,
but using lockfile will avoid similar problems in the future.
- To avoid receiving undecryptable MDNs by bots and replying to them if the bot's key changes.
- MDNs from bots don't look useful in general, usually the user expects some reply from the bot, not
just that the message is read.
Recently there are many questions on the Delta Chat forum why some unexpected encrypted messages
appear in Inbox. Seems they are mainly sync messages, though that also obviously happens to
SecureJoin messages. Anyway, regardless of the `MvboxMove` setting, auto-generated outgoing messages
should be moved to the DeltaChat folder so as not to complicate co-using Delta Chat with other MUAs.
Otherwise cargo emits these warnings:
warning: .../deltachat-core-rust/deltachat-ffi/Cargo.toml: `default-features` is ignored for deltachat, since `default-features` was not specified for `workspace.dependencies.deltachat`, this could become a hard error in the future
warning: .../deltachat-core-rust/deltachat-rpc-server/Cargo.toml: `default-features` is ignored for deltachat, since `default-features` was not specified for `workspace.dependencies.deltachat`, this could become a hard error in the future
warning: .../deltachat-core-rust/deltachat-rpc-server/Cargo.toml: `default-features` is ignored for deltachat-jsonrpc, since `default-features` was not specified for `workspace.dependencies.deltachat-jsonrpc`, this could become a hard error in the future
Previously Delta Chat tried to use local part of email address as well.
This configuration is very uncommon,
but trying it doubled the time of configuration try
in the worst case, e.g. when the password is typed in incorrectly.
Single function smtp::connect::connect_stream
returns a stream of a single `dyn` type
that can be a TLS, STARTTLS or plaintext
connection established over SOCKS5 or directly.
This way we can't get an account with missing blobs if there's not enough disk space.
Also delete already unpacked files if all files weren't unpacked successfully. Still, there are some
minor problems remaining:
- If a db wasn't imported successfully, unpacked blobs aren't deleted because we don't know at which
step the import failed and whether the db will reference the blobs after restart.
- If `delete_and_reset_all_device_msgs()` fails, the whole `import_backup()` fails also, but after a
restart delete_and_reset_all_device_msgs() isn't retried. Probably errors from it should be
ignored at all.
Previously Delta Chat tried all DNS resolution results
in sequence until TCP connection is established successfully,
then tried to establish TLS on top of the TCP connection.
If establishing TLS fails, the whole
connection establishment procedure failed
without trying next DNS resolution results.
In particular, in a scenario
where DNS returns incorrect result
pointing e.g. to a server
that listens on the TCP port
but does not have correpsponding TLS certificate,
Delta Chat now will fall back to the cached result
and connect successfully.
while adapting strings for the recent change about read receipts,
https://github.com/deltachat/deltachat-core-rust/pull/5712 , it turns
out in discussions eg. at
https://github.com/deltachat/deltachat-android/issues/3179 that
untranslated english for the read receipts seem to be sufficient or even
better:
- do not reveal the sender's language
- unexpected languages are confusing - even if you chat in english, you
may get Chinese read receipts
- many clients do not show the text anyways, iirc, eg. Outlook display
the read receipts in context, and Delta Chat of course as well
- afaik, we're leaving comparable `multipart/report` untranslated as
well (sync, but also webxdc updates are practically english only)
- less code, fewer translations needed :)
There are many reasons why we may fail to find valid signatures in a message, e.g. we don't yet know
a public key attached in the same message, anyway, if From is forged, the message must be rejected.
Also always take the displayname from encrypted From, even if no valid signatures are found.
This is a hint for apps that a WebXDC icon should be shown in the summary, e.g. in the
chatlist. Otherwise it's not clear when it should be shown, e.g. it shouldn't be shown in a reaction
summary.
For hardcoded built-in DNS results
there is no cache entry in `dns_cache` table
so they cannot be prioritized if DNS resolution
never returned these results yet.
If there is no entry, a new one should be created.
SQL UPSERT does this.
Follow-up to 3cf78749df "Emit DC_EVENT_MSGS_CHANGED for
DC_CHAT_ID_ARCHIVED_LINK when the number of archived chats with unread messages increases (#3940)".
In general we don't want to make an extra db query to know if a noticied chat is
archived. Emitting events should be cheap, better to allow false-positive `MsgsChanged` events.
`Context::send_sync_msg()` mustn't be called from multiple tasks in parallel to avoid sending the
same sync items twice because sync items are removed from the db only after successful
sending. Let's guarantee this by calling `send_sync_msg()` only from the SMTP loop. Before
`send_sync_msg()` could be called in parallel from the SMTP loop and another task doing
e.g. `chat::sync()` which led to `test_multidevice_sync_chat` being flaky because of events
triggered by duplicated sync messages.
New protocol streams .tar into iroh-net
stream without traversing all the files first.
Reception over old backup protocol
is still supported to allow
transferring backups from old devices
to new ones, but not vice versa.
The "Chat-Group-Member-Removed" header is added to ad-hoc group messages as well, so we should check
for its presense before creating an ad-hoc group as we do for DC-style groups.
Before, update sending might be delayed due to rate limits and later merged into large
messages. This is undesirable for apps that want to send large files over WebXDC updates because the
message with aggregated update may be too large for actual sending and hit the provider limit or
require multiple attempts on a flaky SMTP connection.
So, don't aggregate updates if the size of an aggregated update will exceed the limit of 100
KiB. This is a soft limit, so it may be exceeded if a single update is larger and it limits only the
update JSON size, so the message with all envelopes still may be larger. Also the limit may be
exceeded when updates are sent together with the WebXDC instance when resending it as the instance
size isn't accounted to not complicate the code. At least this is not worse than the previous
behaviour when all updates were attached.
Bridge bots like matterdelta need to set a quoted text without referencing the quoted message, this
makes easier bridging messages from other platforms to Delta Chat or even bridging Delta Chat groups
in different accounts where you can not set a quoted message by the message id from another account.
Even though SMTP ALPN is not officially registered (unlike IMAP),
it is an obvious choice that will allow
to multiplex SMTP and other protocols on the same TLS port.
Newer node-gyp uses newer gyp
which requires newer python
that is not available in Debian 10
container that is
used for building node prebuilds
with old glibc.
Follow-up to 5fa7cff46. Let's still not send a sync message if the contact wasn't modified. This is
not very important, but just for consistency with the `chat::rename_ex()` behaviour.
This way it's clearer which key is which and also adding the key fingerprint to the file name avoids
overwriting another previously exported key. I think this is better than adding an incremental
number as we do for backups, there's no need to export a key several times to different files.
For purposes of building a message it's better to consider the self-chat as verified. Particularly,
this removes unencrypted name from the "From" header.
If currently there are no multi-device bots, let's disable sync messages for bots at all. Another
option is to auto-disable sync messages when `Config::Bot` is set, so sync messages can be reenabled
if needed. But let's leave this option for the future.
About the first TODO: I tried this out, but it didn't actually improve
things, for two reasons:
1. The trick with `#![cfg_attr(not(test),
warn(clippy::indexing_slicing))]` that enables the lint everywhere
except for tests doesn't work with workspace-wide lints. (Context: We
want to lint against indexing because it might panic, but in a test
panicking is fine, so we don't want to enable the lint in tests).
2. Most of our crates have different sets of lints right now, so it
would only be very few crates that use the workspace-wide list of lints.
About the second TODO:
It's not feasible right now to fully parse vCards, and for our
good-enough parser the current behavior is fine, I think. If we fail to
parse some realworld vCards because of this, we can still improve it.
Notification server uses APNS server
for heartbeat notifications,
so registering FCM tokens there
will result in failing to notify them
and unregistering them anyway.
It's possible that when rebasing a PR adding a migration a merge-conflict doesn't occur if another
migration was added in the target branch. Better to have at least runtime checks that the migration
version is correct. Looks like compile-time checks are not possible because Rust doesn't allow to
redefine constants, only vars.
Instead of constructing lists of protected,
unprotected and hidden headers,
construct a single list of headers
and then sort them into separate lists
based on the well-defined policy.
This also fixes the bug
where Subject was not present in the IMF header
for signed-only messages.
Closes#5713
Bot processes are run asynchronously, so we shouldn't send messages to a bot before it's fully
initialised and skipped existing messages for processing, i.e. before DC_EVENT_IMAP_INBOX_IDLE is
emitted.
we're always checking the configuration encrypted.
saying it is 'preferred' encrypted is misleading,
therfore, just remove it.
i do not think, it is worth saying that we do not query 'http',
this is clear from the source code.
moreover, fix two typos.
Looks like it has no sense to send any profile data (From/To names, self-status; self-avatar was
never sent even before) in MDNs, they aren't normal messages and aren't seen in a MUA. Better not to
reveal profile data to the network and even to contacts in MDNs and make them more lightweight.
Follow-up to b771311593. Since that commit names are not revealed in
verified chats, but during verification (i.e. SecureJoin) they are still sent unencrypted. Moreover,
all profile data mustn't be sent even encrypted before the contact verification, i.e. before
"v{c,g}-request-with-auth". That was done for the selfavatar in
304e902fce, now it's done for From/To names and the self-status as
well. Moreover, "v{c,g}-request" and "v{c,g}-auth-required" messages are deleted right after
processing, so other devices won't see the received profile data anyway.
Probably sync messages generated for a not yet configured account are useless because there are no
other devices yet. And even if this is not true, we don't want to depend on the order of setting
`Config::SyncMsgs` and other keys. Also w/o this the Python tests don't work if we start syncing
`Config::MvboxMove` because they don't expect that sync messages are sent while configuring
accounts.
NB: We don't restart IO from the synchronisation code, so `MvboxMove` isn't effective immediately if
`ConfiguredMvboxFolder` is unset, but only after a reconnect to IMAP.
Before, if the user deleted a message too quickly after sending, it was deleted only locally. The
fix is to remember for tombstones that the corresponding message should be deleted on the server
too.
This is a way to prevent redownloading locally deleted messages. Otherwise if a message is deleted
quickly after sending and `bcc_self` is configured, the BCC copy is downloaded and appears as a new
message as it happens for messages sent from another device.
Delta Chat -style groups have names w/o prefixes like "Re: " even if the user is added to an already
existing group, so let's remove prefixes from ad-hoc group names too. Usually it's not very
important that the group is a classic email thread existed before, this info just eats up screen
space. Also this way a group name is likely to preserve if the first message was missed.
SQLite search with `LIKE` is case-insensitive only for ASCII chars. To make it case-insensitive for
all messages, create a new column `msgs.txt_normalized` defaulting to `NULL` (so we do not bump up
the database size in a migration) and storing lowercased/normalized text there when the row is
created/updated. When doing a search, search over `IFNULL(txt_normalized, txt)`.
Before, if `Config::FetchExistingMsgs` is set, existing messages were received with the `InSeen`
state set, but for bots they must be `InFresh` and also `IncomingMsg` events should be emitted for
them so that they are processed by bots as it happens with new messages.
Since commit c0a17df344
(PR https://github.com/deltachat/deltachat-core-rust/pull/3402)
`send_smtp_messages` returns an error
as soon as it encounters the first message it failed to send.
Since this worked like this for about 2 years
without any problems, there is no need to revert the change,
but outdated comment should be removed.
If a display name should be protected (i.e. opportunistically encrypted), only put the corresponding
address to the unprotected headers. We protect the From display name only for verified chats,
otherwise this would be incompatible with Thunderbird and K-9 who don't use display names from the
encrypted part. Still, we always protect To display names as compatibility seems less critical here.
When receiving a messge, overwrite the From display name but not the whole From field as that would
allow From forgery. For the To field we don't really care. Anyway as soon as we receive a message
from the user, the display name will be corrected.

Otherwise it's impossible to remove a member with missing key from a protected group. In the worst
case a removed member will be added back due to the group membership consistency algo.
The "I left the group" message can't be sent to a protected group if some member's key is missing,
in this case we should remain in the group. The problem should be fixed first, then the user may
retry to leave the group.
There was a comment in `fetch_existing_msgs()`: "Bots don't want those messages". If a bot doesn't
want this setting, why enable it? It's disabled by default anyway.
`IsChatmail` is set also by `inbox_fetch_idle()`, but it isn't called during `configure()`. Setting
`IsChatmail` from `inbox_fetch_idle()` is necessary to handle client/server upgrades, but
`IsChatmail` also should be available for the app after configuring an account, e.g. DC Android
needs it to know whether to ask the user to disable battery optimisations.
Before this fix LogSink was dropped immediately,
resulting in no logs printed for contexts created using
TextContext::new_alice(), but printed for contexts created
using TextContext::new().
`!to_ids().is_empty()` check is needed in cases of 1:1 chat creation
because otherwise `to_id` is undefined,
but in case of outgoing group message without recipients
observed on a second device creating a group should be allowed.
Previously OpenSSL was pinned due to problems
with Zig toolchain used back then
and then not unpinned even after switching from Zig to Nix
due to <https://github.com/alexcrichton/openssl-src-rs/issues/235>.
The problem should be fixed now
and we can try to unpin OpenSSL again.
When doing an AEAP transition, we mustn't just delete the old peerstate as this would break
encryption to it. This is critical for non-verified groups -- if we can't encrypt to the old
address, we can't securely remove it from the group (to add the new one instead).
-remove `DELTA_CHAT_SKIP_PATH` environment variable

async-broadcast returns Overflowed error once
if channel overflow happened.
Public APIs such as get_next_event JSON-RPC method
are only expecting an error if the channel is closed,
so we should not propagate overflow error outside.
In particular, Delta Chat Desktop
stop receiving events completely if an error
is returned once.
If overflow happens, we should ignore it
and try again until we get an event or an error because
the channel is closed (in case of recv())
or empty (in case of try_recv()).
If multiple headers with the same name are present,
we must take the last one.
This is the one that is DKIM-signed if
this header is DKIM-signed at all.
Ideally servers should prevent adding
more From, To and Cc headers by oversigning
them, but unfortunately it is not common
and OpenDKIM in its default configuration
does not oversign any headers.
closes#5533
adds the functions that were still missing for migration to jsonrpc (the
ones that the cffi already had, so just should be quick to review ;)
It's actually `deltachat::contact::Contact::authname` by semantics. `display_name`/`name` shouldn't
be shared, it's the name given by the user locally.

When there are no parent references,
Delta Chat inserts Message-ID into References.
Such references should be ignored
because otherwise fully downloaded message
may be assigned to the same chat as previously incorrectly assigned
partially downloaded message.
Fixes receive_imf::tests::test_create_group_with_big_msg
Chat-Group-ID always correctly identifies the chat
message was sent to, while In-Reply-To and References
may point to a message that has itself been incorrectly
assigned to a chat.
This protects Bob (the joiner) of sending unexpected-unencrypted messages during an otherwise nicely
running SecureJoin.
If things get stuck, however, we do not want to block communication -- the chat is just
opportunistic as usual, but that needs to be communicated:
1. If Bob's chat with Alice is `Unprotected` and a SecureJoin is started, then add info-message
"Establishing guaranteed end-to-end encryption, please wait..." and let `Chat::can_send()` return
`false`.
2. Once the info-message "Messages are guaranteed to be e2ee from now on" is added, let
`Chat::can_send()` return `true`.
3. If after SECUREJOIN_WAIT_TIMEOUT seconds `2.` did not happen, add another info-message "Could not
yet establish guaranteed end-to-end encryption but you may already send a message" and also let
`Chat::can_send()` return `true`.
Both `2.` and `3.` require the event `ChatModified` being sent out so that UI pick up the change wrt
`Chat::can_send()` (this is the same way how groups become updated wrt `can_send()` changes).
SECUREJOIN_WAIT_TIMEOUT should be 10-20 seconds so that we are reasonably sure that the app remains
active and receiving also on mobile devices. If the app is killed during this time then we may need
to do step 3 for any pending Bob-join chats (right now, Bob can only join one chat at a time).
`ChatId::lookup_by_contact()` returns `None` for blocked chats, so it should be only used if we need
to filter out blocked chats, e.g. when building a chatlist.
E.g. the multi-device synchronisation creates the "Saved Messages" chat as blocked, in this case the
chat icon wasn't updated before and the user avatar was displayed instead.

this PR checks if the quotes are used in a reasonable way:
- quoted messages should be send to the same chat
- or to one-to-one chats
if the quote's chat ID is not the same than the sending chat _and_ the
sending chat is not a one-to-one chat, sending is aborted.
usually, the UIs does not allow quoting in other ways, so, this check is
only a "last defence line" to avoid leaking data in case the UI has
bugs, as recently in
https://github.com/deltachat/deltachat-android/issues/3032
@iequidoo @link2xt @adbenitez i am not 100% sure about this PR, maybe
i've overseen a reasonable usecase where other quotes make sense

Otherwise, e.g. if a message is a large GIF, but its viewtype is set to `Image` by the app, this GIF
will be recoded to JPEG to reduce its size. GIFs and other special viewtypes must be always detected
and sent as is.
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 is similar to `test_modify_chat_disordered`,
but tests that recovery works in the simplest case
where next message is not modifying group membership.
... and fails if file already exists. The UI should open the file saving dialog, defaulting to
Downloads and original filename, when asked to save the file. After confirmation it should call
dc_msg_save_file().
This way we avoid an immediate retry if the network is not yet ready exhausting the ratelimiter's
quota of two connection attempts. Also notify the ratelimiter only after a successful connection so
that it only limits the server load, but not connection attempts.
Otherwise an error
"The encoder or decoder for Jpeg does not support the color type `Rgba8`"
is returned if image has an alpha channel.
This is caused by the recent change of JPEG encoder
in `image` crate: <https://github.com/image-rs/image/issues/2211>
This makes `EventTracker` receive events immediately
instead of being moved from event emitter to event tracker
by a task spawned from `TestContext::new_internal`.
This makes `EventTracker.clear_events` reliable
as it is guaranteed to remove all events emitted
by the time it is called rather than only events
that have been moved already.
as discussed in several chats, this PR starts making it possible to use
Webxdc as integrations to the main app. In other word: selected parts of
the main app can be integrated as Webxdc, eg. Maps [^1]
this PR contains two parts:
- draft an Webxdc Integration API
- use the Webxdc Integration API to create a Maps Integration
to be clear: a Webxdc is not part of this PR. the PR is about marking a
Webxdc being used as a Map - and core then feeds the Webxdc with
location data. from the view of the Webxdc, the normal
`sendUpdate()`/`setUpdateListener()` is used.
things are still marked as "experimental", idea is to get that in to
allow @adbenitez and @nicodh to move forward on the integrations into
android and desktop, as well as improving the maps.xdc itself.
good news is that we currently can change the protocol between Webxdc
and core at any point :)
# Webxdc Integration API
see `dc_init_webxdc_integration()` in `deltachat.h` for overview and
documentation.
rust code is mostly in `webxdc/integration.rs` that is called by other
places as needed. current [user of the API is
deltachat-ios](https://github.com/deltachat/deltachat-ios/pull/1912),
android/desktop will probably follow.
the jsonrpc part is missing and can come in another PR when things are
settled and desktop is really starting [^2] (so we won't need to do all
iterations twice :) makes also sense, when this is done by someone
actually trying that out on desktop
while the API is prepared to allow other types of integrations (photo
editor, compose tools ...) internally, we currently ignore the type. if
that gets more crazy, we probably also need a dedicated table for the
integrations and not just a single param.
# Maps Integration
rust code is mostly in `webxdc/maps_integration.rs` that is called by
`webxdc/integration.rs` as needed.
EDIT: the idea of having a split here, is that
`webxdc/maps_integration.rs` really can focus on the json part, on the
communication with the .xdc, including tests
this PR is basic implementation, enabling to move forward on
integrations on iOS, but also on desktop and android.
the current implementation allows already the following:
- global and per-chat maps
- add and display POIs
- show positions and tracks of the last 24 hours
the current maps.xdc uses leaflet, and is in some regards better than
the current android/desktop implementations (much faster, show age of
positions, fade out positions, always show names of POIs, clearer UI).
however, we are also not bound to leaflet, it can be anything
> [**screenshots of the current
state**](https://github.com/deltachat/deltachat-ios/pull/1912)
> 👆
to move forward faster and to keep this PR small, the following will go
to a subsequent PR:
- consider allowing webxdc to use a different timewindow for the
location
- delete POIs
- jsonrpc
[^1]: maps are a good example as anyways barely native (see android
app), did cause a lot of pain on many levels in the past (technically,
bureaucratically), and have a comparable simple api
[^2]: only going for jsonrpc would only make sense if large parts of
android/ios would use jsonrpc, we're not there

As trashed messages can't be loaded from the db now by `Message::load_from_db()` returning an error
for such messages, errors from `Message::load_from_db()` should be logged as warnings. If it's
really an error like a db failure, it should be logged internally.
As trashed messages can't be loaded from the db now, `get_message_by_id()` returns None in some
tests e.g. in `test_deleted_msgs_dont_reappear()`. A `PerAccount` hook shouldn't be called if so.
There's no need to load an updated message state from the db to implement `is_outgoing()` and also
this function is implicitly called in some tests where a message is already trashed and a call to
`dc_get_msg()` generates an unexpected error.
Previously test did not trigger
deletion of ephemeral messages
and worked because clear_events() did not
remove just emitted events from `send_text_msg`.
It keeps timing out with the default timeout of 2 s on macOS runners.
Also fix comment in the integration test which
said that timeout is 1 minute but sets it to 3 minutes.
Set this timeout to 5 minutes as well.
API now pretends that trashed messages don't exist.
This way callers don't have to check if loaded message
belongs to trash chat.
If message may be trashed by the time it is attempted to be loaded,
callers should use Message::load_from_db_optional.
Most changes are around receive_status_update() function
because previously it relied on loading trashed status update
messages immediately after adding them to the database.
This way nightly clippy warnings are not generated
when devshell is used.
Nighly Rust is also not cached, e.g. rust-analyzer has to be rebuilt
if version from fenix is used.
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.
`a.clone_from(&b)` is equivalent to `a = b.clone()` in functionality,
but can be overridden to reuse the resources of a to avoid unnecessary
allocations.
When the env var CARGO_BUILD_TARGET is set, cargo will crossbuild for the given arch triplet. In this case, the targets will not be put into target/release/, but target/$CARGO_BUILD_TARGET/release/. Add this subdirectory, if neccessary.
If `delete_device_after` is configured, that period should be counted for webxdc instances from the
last status update, otherwise nothing prevents from deleting them. Use `msgs.timestamp_rcvd` to
store the last status update timestamp, it anyway isn't used for anything except displaying a
detailed message info. Also, as `ephemeral::select_expired_messages()` now also checks
`timestamp_rcvd`, we have an improvement that a message is guaranteed not to be deleted for the
`delete_device_after` period since its receipt. Before only the sort timestamp was checked which is
derived from the "sent" timestamp.
Let's add a 1-minute tolerance to `Params::MemberListTimestamp`.
This adds to the group membership consistency algo the following properties:
- If remote group membership changes were made by two members in parallel, both of them are applied,
no matter in which order the messages are received.
- If we remove a member locally, only explicit remote member additions/removals made in parallel are
allowed, but not the synchronisation of the member list from "To". Before, if somebody managed to
reply earlier than receiving our removal of a member, we added it back which doesn't look good.
This change avoids the race between
`provide_backup` changing the state from NoProvider to Pending
and a call to `get_backup_qr` or `get_backup_qr_svg`.
With this change `get_backup_qr` and `get_backup_qr_svg`
always block until QR code is available,
even if `provide_backup` was not called yet.
- Always emit `ContactsChanged` from `contact::update_last_seen()` if a contact was seen recently
just for simplicity and symmetry with `RecentlySeenLoop::run()` which also may emit several events
for single contact.
- Fix sleep time calculation in `RecentlySeenLoop::run()` -- `now` must be updated on every
iteration, before the initial value was used every time which led to progressively long sleeps.
Instead, look up the 1:1 chat in `receive_imf::add_parts()`. This is a more generic approach to fix
assigning outgoing reactions to 1:1 chats in the multi-device setup. Although currently both
approaches give the same result, this way we can even implement a "react privately"
functionality. Maybe it sounds useless, but it seems better to have less reaction-specific code.
we checked for tombstones already using `is_trash()`,
however, we've overseen that tombstones get deleted at some point :)
therefore, just do not treat loading failures of the weak msg_id as errors -
usually, they are not - and if, just the normal summary is shown.
in theory, we could check for existance explicitly before tryong load_from_db,
however, that would be additional code (and maybe another database call)
and not worth the effort.
anyways, this commit also adds an explicit test
for physical deletion after housekeeping.
use get_summary_text_without_prefix() to get raw summaries without prefixes,
this is needed for reaction summaries,
where we also do not show the name, so we do not want to show "Forwarded" as well.
shows the last reaction in chatlist's summaries if there is no
newer message.
the reason to show reactions in the summary, is to make them a _little_
more visible when one is not in the chat. esp. in not-so-chatty or in
one-to-ones chats this becomes handy: imaging a question and someone
"answers" with "thumbs up" ...
otoh, reactions are still tuned down on purpose: no notifications, chats
are opend as usual, the chatlist is not sorted by reactions and also the
date in the summary refer to the last message - i thought quite a bit
about that, this seems to be good compromise and will raise the fewest
questions. it is somehow clear to the users that reactions are not the
same as a real message. also, it is comparable easy to implement - no
UI changes required :)
all that is very close to what whatsapp is doing (figured that out by
quite some testing ... to cite @adbenitez: if in doubt, we can blame
whatsapp :)
technically, i first wanted to go for the "big solution" and add two
more columns, chat_id and timestamp, however, it seemed a bit bloated if
we really only need the last one. therefore, i just added the last
reaction information to the chat's param, which seems more performant
but also easier to code :)
`is_probably_private_reply()` checks
if a message should better go to the one to one chat
instead of the chat already identified by the `In-Reply-To`.
this functionality is needed to make "Reply Privately" work.
however, this functionality is never true for reactions.
if we would return `true` here, own reactions seen by a second device
would not get the correct chat assiged.
We update version in several .toml and .json files
on every release anyway, so updating pyproject.toml is easy.
setuptools_scm makes it more difficult to build
python packages for software distributions
because it requires full git checkout
with tags rather than just a worktree.
It is also possible to remove or move tags
after the release, so git revision no longer
pins python package version if setuptools_scm is used.
- the `jobs` table is no longer in use,
no need to track files on housekeeping,
no need to clear it from repl tool
- some `Params` were used for jobs table only,
they can be used freely for other purposes on other tables.
param 'protection settings timestamp' was never used in practise,
its code is removed as well, so we can free the Param as well.
it was used by iOS to know when a background fetch was complete;
meanwhile the superiour `dc_accounts_background_fetch()` is used for
that.
there is still the corresponding context function `dc_all_work_done()`,
this not used by any UI as well, however, it is in use by a python
tests.
not sure, what to do with it, at a first glance, the test still seems
useful.
Don't attach selfavatar in "v{c,g}-request" and "v{c,g}-auth-required" messages:
- These messages are deleted right after processing, so other devices won't see the avatar.
- It's also good for privacy because the contact isn't yet verified and these messages are auto-sent
unlike usual unencrypted messages.
the rendered time output seems different on different systems and timezomes,
eg. on my local machine, it is
`Sent: 2024.03.20 10:00:01 ` and not `Sent: 2024.03.20 09:00:01`,
maybe because of winter/summer time, idk.
as the gist of the test is to check the name,
however, i just removed the whole time check.
Do not include oldest reference, because chat members
which have been added later and have not seen the first message
do not have referenced message in the database.
Instead, include up to 3 recent Message-IDs.
If user specifies build directory, respect this
instead of building inside the target/ directory.
Also remove outdated comment about Rust 1.50.0 support.
Current MSRV is 1.70.0 and we use 2021 edition
which implies version 2 resolver.
This is a test reproducing the problem
in <https://github.com/deltachat/deltachat-core-rust/issues/5339>.
Fix would be to avoid reordering on the server side,
so the test checks that the unverified message
is replaced with a square bracket error
as expected if messages arrive in the wrong order.
Add white background instead of the default black one to avatars when recoding to JPEG. But not for
"usual" images to spare the CPU. The motivation is to handle correctly
"black-on-transparent-background" avatars which are quite common.
as turned out on recent researches wrt a slow database, setting
`save_mime_headers` will result in 25x larger databases.
this is definetely something we want to know at least in the debug info.
(the option cannot be enabled in current UIs,
however, esp. devs find options to set this.
apart from that, save_mime_headers is only used in some python tests)
ftr: the huge database was more than 10 times slower, leading to missing
notifications on ios (as things do not finish within the few seconds iOS
gave us).
moreover, the hugeness also avoids exporting; this is fixed by
https://github.com/deltachat/deltachat-core-rust/pull/5349
this PR fixes one of the issues we had with an (honestly accidentally)
huge database of >2gb.
this database could not be exported on iOS, as ram memory is limited
there, leading to the app just crashing.
it is unclear if that would be better on eg. Android, however,
temp_store=FILE is not working as well there, this is the smaller
drawback there.
before merging, this PR should be tested on time with export/import on
iOS (export/import uses VACUUM which uses /tmp) EDIT: did so, works on
iphone7 with ios15
`Param::MemberListTimestamp` was updated only from `receive_imf::apply_group_changes()` i.e. for
received messages. If we sent a message, that timestamp wasn't updated, so remote group membership
changes always overrode local ones. Especially that was a problem when a message is sent offline so
that it doesn't incorporate recent group membership changes.
When scheduler is destroyed, e.g. during a key import,
there is some time between destroying the interrupt channel
and the loop task.
To avoid busy looping, tasks should terminate if
receiving from the interrupt loop fails
instead of treating it as the interrupt.

- over jsonrpc built with napi.rs (experimental): \[[📂 source](https://github.com/deltachat/napi-jsonrpc) | [📦 npm](https://www.npmjs.com/package/@deltachat/napi-jsonrpc)\]

We format the code using `rustfmt`. Run `cargo fmt` prior to committing the code.
Run `scripts/clippy.sh` to check the code for common mistakes with [Clippy].
[Clippy]: https://doc.rust-lang.org/clippy/
## SQL
Multi-line SQL statements should be formatted using string literals,
for example
```
sql.execute(
"CREATE TABLE messages (
id INTEGER PRIMARY KEY AUTOINCREMENT,
text TEXT DEFAULT '' NOT NULL -- message text
) STRICT",
)
.await?;
```
Do not use macros like [`concat!`](https://doc.rust-lang.org/std/macro.concat.html)
or [`indoc!](https://docs.rs/indoc).
Do not escape newlines like this:
```
sql.execute(
"CREATE TABLE messages ( \
id INTEGER PRIMARY KEY AUTOINCREMENT, \
text TEXT DEFAULT '' NOT NULL \
) STRICT",
)
.await?;
```
Escaping newlines
is prone to errors like this if space before backslash is missing:
```
"SELECT foo\
FROM bar"
```
Literal above results in `SELECT fooFROM bar` string.
This style also does not allow using `--` comments.

Declare new SQL tables with [`STRICT`](https://sqlite.org/stricttables.html) keyword
to make SQLite check column types.
Declare primary keys with [`AUTOINCREMENT`](https://www.sqlite.org/autoinc.html) keyword.
This avoids reuse of the row IDs and can avoid dangerous bugs
like forwarding wrong message because the message was deleted
and another message took its row ID.
Declare all new columns as `NOT NULL`
and set the `DEFAULT` value if it is optional so the column can be skipped in `INSERT` statements.
Dealing with `NULL` values both in SQL and in Rust is tricky and we try to avoid it.
If column is already declared without `NOT NULL`, use `IFNULL` function to provide default value when selecting it.
Use `HAVING COUNT(*) > 0` clause
to [prevent aggregate functions such as `MIN` and `MAX` from returning `NULL`](https://stackoverflow.com/questions/66527856/aggregate-functions-max-etc-return-null-instead-of-no-rows).
Don't delete unused columns too early, but maybe after several months/releases, unused columns are
still used by older versions, so deleting them breaks downgrading the core or importing a backup in
an older version. Also don't change the column type, consider adding a new column with another name
instead. Finally, never change column semantics, this is especially dangerous because the `STRICT`

The JSON-RPC API is exposed in two fashions:
* A executable that exposes the JSON-RPC API through a [WebSocket](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API) server running on localhost.
* The JSON-RPC API can also be called through the [C FFI](../deltachat-ffi). The C FFI needs to be built with the `jsonrpc` feature. It will then expose the functions `dc_jsonrpc_init`, `dc_jsonrpc_request`, `dc_jsonrpc_next_response` and `dc_jsonrpc_unref`. See the docs in the [header file](../deltachat-ffi/deltachat.h) for details.

## Usage
#### Running the WebSocket server
From within this folder, you can start the WebSocket server with the following command:
```sh
cargo run --features webserver
```
If you want to use the server in a production setup, first build it in release mode:
```sh
cargo build --features webserver --release
```
You will then find the `deltachat-jsonrpc-server` executable in your `target/release` folder.
The executable currently does not support any command-line arguments. By default, once started it will accept WebSocket connections on `ws://localhost:20808/ws`. It will store the persistent configuration and databases in a `./accounts` folder relative to the directory from where it is started.
The server can be configured with environment variables:
|variable|default|description|
|-|-|-|
|`DC_PORT`|`20808`|port to listen on|
|`DC_ACCOUNTS_PATH`|`./accounts`|path to storage directory|
If you are targeting other architectures (like KaiOS or Android), the webserver binary can be cross-compiled easily with [rust-cross](https://github.com/cross-rs/cross):
The package includes a JavaScript/TypeScript client which is partially auto-generated through the JSON-RPC library used by this crate ([yerpc](https://github.com/Frando/yerpc/)). Find the source in the [`typescript`](typescript) folder.

## MVP - Websocket server&client
For kaiOS and other experiments, like a deltachat "web" over network from an android phone.
- [ ] coverage for a majority of the API
- [ ] Blobs served
- [ ] Blob upload (for attachments, setting profile-picture, importing backup and so on)
- [ ] other way blobs can be addressed when using websocket vs. jsonrpc over dc-node
- [ ] Web push API? At least some kind of notification hook closure this lib can accept.
### Other Ideas for the Websocket server
- [ ] make sure there can only be one connection at a time to the ws
- why? , it could give problems if its commanded from multiple connections
- [ ] encrypted connection?
- [ ] authenticated connection?
- [ ] Look into unit-testing for the proc macros?

Incomplete todo for desktop api porting, just some remainders for points that might need more work:
- [ ] manual start/stop io functions in the api for context and accounts, so "not syncing all accounts" can still be done in desktop -> webserver should then not do start io on all accounts by default
