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.
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 :)
rust-analyzer was showing warnings here because it is always also
building in the Test configuration, and EventType has a
```rust
#[cfg(test)]
Test,
```
variant, which was not matched.
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
```
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 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
