In particular TLSRPT reports
contain files that may be interesting for admins.
Currently Delta Chat drops the attachment
so message appears as a text message without actual payload.
If we wait for inviter success,
vg-member-added message may be still in flight
and reach ac2 after device resetup.
Making ac2 wait for joining the group ensures that old
device receives vg-member-added message
and new device will not receive it and fail to decrypt.
Other instances of wait_for_securejoin_inviter_success()
in the same tests are also replaced for reliability.
Previously the message was removed from `download` table,
but message bubble was stuck in InProgress state.
Now download state is updated by the caller,
so it cannot be accidentally skipped.
Trying non-strict TLS checks is not necessary
for most servers with proper TLS setup,
but doubles the time needed to fail configuration
when the server is not responding, e.g.
when all connection attempts time out.
There is also a risk of accidentally
configuring non-strict TLS checks in a rare case
that strict TLS check configuration spuriously failed,
e.g. on a bad network.
If the server has a known broken TLS setup,
it can still be added to the provider database
or configured with non-strict TLS check manually.
User can also configure another email provider,
such as chatmail servers, instead of using the server
with invalid TLS hostname.
This change does not affect exising setups.
deltachat.h uses `@defgroup` commands to create topics
for groups of constants. Prior to Doxygen 1.9.8
defining a group created a "module"
and all constants were visible from the modules.html page.
In Doxygen 1.9.8 "modules" were renamed into "topics"
as C++20 modules have taken their place,
so Delta Chat documentation does not have modules
in Doxygen sense anymore.
The change is to replace "modules.html" with "topics.html"
in the DoxygenLayout.xml.
See <https://www.doxygen.nl/manual/grouping.html> for
Doxygen documentation about groups and their relation to topics.
Mark 1:1 chat as verified as soon as Alice is forward-verified
so Bob can already start sending Chat-Verified headers.
This way Alice and Bob can scan each other's QR codes
and even if all Secure-Join headers are dropped from the network,
still get forward verifications via QR-code scans
and backward verifications via Chat-Verified messages in 1:1 chat.
Before this fix actual contents of the message
reposted by Schleuder is considered a mailing list footer and removed,
not visible even in the "Show Full Message..." view.
With this change there will be two message bubbles,
one for header and one for the contents,
but it is still better than losing the contents completely.
Attempting to parse header part is out of scope for this change.
This is broken since 44227d7b86
mimeparser only recognizes read receipts
by the Content-Type being "multipart/report".
If multipart/report is hidden inside multipart/mixed
and the message is not encrypted,
it degrades encryption.
As ratelimit was introduced to avoid reconnecting immediately after disconnecting
in case of bugs in IMAP protocol handling,
connection attempts should only be counted when IMAP is actually used,
i.e. when the first command (LOGIN) is sent.
We do not want all_work_done() to return true immediately
after calling start_io(), but only when connection goes idle.
"Connected" state is set immediately after connecting to the server,
but it does not mean there is nothing to do.
This change make all_work_done() return false
from the Connected state and introduces a new Idle
connectivity state that is only set before connection
actually goes idle. For idle state all_work_done() returns true.
From the user point of view both old Connected state
and new Idle state look the same.
This change depends on async-imap update that resets the timeout
every time an `* OK Still here` is received.
Reducing timeout allows to detect lost connections
not later than 6 minutes
because Delta Chat will attempt to finish IDLE with DONE
after 5 minutes without keepalives
and will either get TCP RST directly
or, worst case, wait another minute for TCP socket read timeout.
- Use TestContextManager
- Actually run receive_imf rather than only mimeparser on "received" messages
- Check that received message parts actually have a padlock
parse_mime_recursive() skips empty text parts,
so there may be no parts as the result of parsing.
In this case an empty part is added.
However, because it is added with parts.push()
rather than add_single_part(),
it is added without a padlock even if the message is encrypted.
`do_add_single_part()` adds padlock (GuaranteeE2EE param)
and should be used to add parts instead.
This test reproduces a bug preventing joining the group with a QR code
if the group already has a contact with inconsistent key state,
which means both Autocrypt and verified key exist,
but don't match.
This can happen when an invite QR code created by this contact
is scanned as scanning an invite code creates unprotected group
with the inviter for info messages.
If securejoin process never finishes because the inviter is offline,
group remains in this unprotected state with added inviter.
Normally the group becomes verified when a "Member added" (vg-member-added)
message is received in the chat.
However, current code checks that all members
of the chat are verified
(have a green checkmark, use verified key in 1:1 chat)
before marking the group as verified and fails otherwise.
- Remove "Detected Autocrypt-mime message" logs printed for every incoming Autocrypt message.
- Print only a single line at the beginning of receive_imf with both the Message-ID and seen flag.
- Print Securejoin step only once, inside handle_securejoin_handshake or observe_securejoin_on_other_device.
- Do not log "Not creating ad-hoc group" every time ad-hoc group is not created, log when it is created instead.
- Log ID of the chat where Autocrypt-Gossip for all members is received.
- Do not print "Secure-join requested." for {vg,vc}-request, we already log the step.
- Remove ">>>>>>>>>>>>>>>>>>>>>>>>>" noise from securejoin logs.
Allowing outgoing unencrypted messages in groups with 2 members
breaks the test
`python/tests/test_0_complex_or_slow.py::test_verified_group_vs_delete_server_after`
This centralizes all Securejoin/verification checks and updates in one
place right before add_parts() even before we assign the message to
the chat, so we can decouple chat logic from verification logic.
Currently this leads to
