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 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.
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.
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.
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
```
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
