This change separates rendering into two separate steps:
1. Rendering of the message payload without the From, Date and Autocrypt headers.
2. Adding the From, Date and Autocrypt headers and possibly encrypting the message.
The goal is to have serializable result of the first step
that can be persisted in the database and sent later with any email address.
This way it will be possible to send queued messages over any relay.
This will make it possible not to remove all messages from the queue
when the sending relay is changed.
Currently changing `configured_addr` deletes everything from `smtp` table.
This change is however only a refactoring and does not implement any features.
Otherwise users may add up to 5 relays, but 2 oldest relays
are actually ignored.
Having the maximum number of published relays
and the number of relays used the same between all clients
makes the order of relays in the key irrelevant.
We may even remove sorting by `add_timestamp`
from `get_all_self_addrs()` in the future.
EventThread is created in Account.__init__,
but the thread start may be scheduled later.
If the thread only cals dc_get_event_emitter()
after some events have been emitted,
EventThread will never capture such events
and the tests will timeout waiting for the event.
This happened in CI on a Linux runner
with test_markseen_invalid_message_ids
timing out waiting for DC_EVENT_MSGS_CHANGED
right after sending a message.
The lint is reasonable, but without some work
to bring the future sizes way below the limit,
this lint is frequently triggered in unrelated PRs
that just add some local variables to async functions
or extend some structure that is passed on the stack.
Largest change is in the FFI crate.
With 2024 (but not 2021) edition unsafe code
inside unsafe functions should be marked separately
so we can mark exactly the code that is unsafe.
Some CFFI functions even have no unsafe code inside.
Most interesting change is that .strdup()
functions are not marked as unsafe anymore.
They are allocating memory and return raw pointers,
but there is nothing unsafe about it.
Only using the returned raw pointers is unsafe.
This way calls to .strdup() don't have to be marked
with unsafe{} blocks.
Enabling brotli does not add new dependencies,
we have it already.
Documentation at <https://docs.rs/rustls/0.23.42/rustls/compress/>
recommends enabling at least brotli.
zlib feature is not enabled as it pulls in duplicate zlib-rs 0.6.6
zlib was even never supported in Chromium (while brotli is).
It might still be interesting to enable it in the future
because it seems to be the only option supported by OpenSSL
and there may be servers that support zlib but not brotli.
RFC 8879 specifies zstd as well, but there is no feature to enable it yet.
This also brings back explicit TLS 1.2 feature that was reverted.
We don't want TLS 1.2 support to be accidentally dropped
if no dependencies explicitly require it anymore.
https://docs.npmjs.com/trusted-publishers recommends node-version 24
and not updating npm separately, this change copies the recommended configuration.
Also update node version to 24 in non-release workflows, version 18 is EOL.
There is a version 26 already, but 24 is LTS.
Also disable cache for release pipelines.
Before this change "Err" case spams the logs with
"Failed to download message rfc724_mid=...: IMAP location for ... post-message is unknown."
logged by every transports when the message is not available on any transport.
Network errors such as timeouts should not break out of the loop
by bubbling up errors. There may be more candidates to try,
breaking out of the loop skips trying them.
This is a follow-up to 8f51c7b9d5
which removed sync_seen_flags().
MODSEQ is a message attribute related to
CONDSTORE IMAP extension and is not used anymore
since CONDSTORE is not used.
We use the timestamp of the latest transport modification
as the timestamp of the Direct Key Signature.
However, first transport is created before the public key
and existing transports may even have zero timestamp
if they were created before migration 142.
For interoperability with Sequoia-PGP,
make sure signatures always have a timestamp
that is not in the past compared to the timestamp
of the primary key.
It is needed to speed up "DELETE FROM imap_markseen_new WHERE id = ?".
Otherwise if imap_markseen table grows large,
marking a lot of messages at once as seen and trying to delete them one by one
from imap_markseen table may have quadratic complexity.
With madmail 2.2.2 from https://github.com/themadorg/madmail/releases/download/v2.2.2/madmail-linux-amd64
using IMAP command SETMETADATA to set /private/devicetoken
returns error "A0003 BAD command not supported".
With this change connection is not aborted anymore
and the error is logged like this:
src/scheduler.rs:458: Transport 1: Failed to register push token: SETMETADATA command failed: bad response: code: None, info: Some("command not supported").
madmail 2.2.2 however fails to select the INBOX afterwards
and the following command `A0004 SELECT "INBOX"`
results in `* BAD command not supported` response.
Fixes https://github.com/chatmail/core/issues/8334
Arbitrary timeouts often result in flaky tests,
especially if CI runners may be paused.
In this case however timeout was not used by any tests
and only slowed down the tests in cases where
no message is expected but non-zero timeout is set.
Webxdc updates go to pre-message and when the message has no text,
the whole pre-message is trashed if it has a webxdc update.
The solution is not to trash pre-message in this case so preview is displayed.
aws-lc-rs is the default provider for Rustls.
We have been using ring as the default provider
to avoid duplicate dependency
because iroh supports only ring in 0.35.0,
but with version 1.0 it will be possible
to select other crypto providers
and we can switch to using more common default.
This change also enables "tls12" feature explicitly,
otherwise if there is no other dependency
requiring it, only TLS 1.3 will be supported
and we want to keep supporting TLS 1.2.
This hack was needed to "build" Android packages
by repackaging Linux packages on-the-fly,
but PyPI has since added Android support
and we are using it directly.
crates.io recently started rejecting requests to https://crates.io/api/v1/crates
made by Nix: https://github.com/rust-lang/crates.io/issues/13482
This resulted in failing to download any dependencies
from crates.io with 403 error during Rust package builds.
The problem was solved in nixpkgs by switching
to CDN URL https://static.crates.io/crates
in https://github.com/NixOS/nixpkgs/pull/524985
As of writing this on 2026-05-29
the fix is on "master" branch of nixpkgs,
but not on "nixos-unstable" or "nixpkgs-unstable"
branches yet according to https://nixpk.gs/pr-tracker.html?pr=524985
so I have switched nixpkgs to "master" branch to get the problem fixed.
naersk needs a similar fix. I opened a PR for it
https://github.com/nix-community/naersk/pull/391
but because the fix is not merged yet,
switched to my PR branch in flake.nix.
Updating nixpkgs required some minor changes,
e.g. sphinx_rtd_theme has been renamed to sphinx-rtd-theme,
pthreads in Windows builds had to be moved to buildInputs to fix
"Refusing to evaluate package 'mingw_w64-pthreads-13.0.0'
in /nix/store/f78lkqnk63pd0kf52zf2wcx35p1nnalr-source/pkgs/os-specific/windows/mingw-w64/headers.nix:35
because it is not available on the requested hostPlatform"
receive_imf should not fail in this case,
but trash the post-message and updates.
The problem with previously used message::rfc724_mid_exists check
was that rfc724_mid_exists may return a trashed message.
"[::1]" is not a hostname, but an IPv6 address,
and should be passed as "::1" to tokio::net functions.
Otherwise connecting to proxy addresses such as `socks5://[::1]:9150`
fails by trying to resolve IPv6 address with DNS.
This info is added at the top of the logs
and we don't want users to send us the logs
with the key fingerprint for debugging,
it is not really useful but identifies the profile.
This change is a preparation for ignoring
unencrypted messages by default.
New test_utils::encrypt_raw_message and
test_utils::receive_encrypted_imf are
used to encrypt the messages before
"receiving" them with receive_imf.
