Latest versions 0.0.248 and 0.0.249 report false positive:
src/deltachat_rpc_client/client.py:105:9: RET503 [*] Missing explicit `return` at the end of function able to return
.call() interface is safer because it ensures
that blocking operations on SQL connection
are called within tokio::task::block_in_place().
Previously some code called blocking operations
in async context, e.g. add_parts() in receive_imf module.
The underlying implementation of .call()
can later be replaced with an implementation
that does not require block_in_place(),
e.g. a worker pool,
without changing the code using the .call() interface.
IIRC, this was written this way back when we didn't have config caching,
in order to save database accesses by getting the config outside the
for loop.
Gmail archives messages marked as `\Deleted` by default if those messages aren't in the Trash. But
if move them to the Trash instead, they will be auto-deleted in 30 days.
With the introduction of transactions in Contact::add_or_lookup(),
python tests sometimes fail to create contacts with the folowing error:
Cannot create contact: add_or_lookup: database is locked: Error code 5: The database file is locked
`PRAGMA busy_timeout=60000` does not affect
this case as the error is returned before 60 seconds pass.
DEFERRED transactions with write operations need
to be retried from scratch
if they are rolled back
due to a write operation on another connection.
Using IMMEDIATE transactions for writing
is an attempt to fix this problem
without a retry loop.
If we later need DEFERRED transactions,
e.g. for reading a snapshot without locking the database,
we may introduce another function for this.
When connection pool is organized as a stack,
it always returns most recently used connection.
Because each connection has its own page cache,
using the connection with fresh cache improves performance.
I commented out `oauth2::tests::test_oauth_from_mx`
because it requires network connection,
turned off the Wi-Fi and ran the tests.
Before the change, with a queue:
```
$ hyperfine "cargo test"
Benchmark 1: cargo test
Time (mean ± σ): 56.424 s ± 4.515 s [User: 183.181 s, System: 128.156 s]
Range (min … max): 52.123 s … 68.193 s 10 runs
```
With a stack:
```
$ hyperfine "cargo test"
Benchmark 1: cargo test
Time (mean ± σ): 29.887 s ± 1.377 s [User: 101.226 s, System: 45.573 s]

```
On version 1.107.1:
```
$ hyperfine "cargo test"
Benchmark 1: cargo test
Time (mean ± σ): 43.658 s ± 1.079 s [User: 202.582 s, System: 50.723 s]
Range (min … max): 41.531 s … 45.170 s 10 runs
```
This also removes BackupProvider::join in favour of implementing
Future directly. I wondered about implementing a FusedFutre to make
this a little safer but it would introduce a dependency on the futures
crate in deltachat-ffi which did not exist yet, so I didn't do that.
the axum update broke the websocket server, because yerpc still uses a the old 5.9 version.
So I needed to downgrade the dependency until https://github.com/deltachat/yerpc/pull/35 is merged.
I want to retry the kaiOS client experiment, for this I need a working websocket server binary.
We no longer need that in the transfer case, that would give very
weird results. This also means there is nothing imex-specific about
this anymore so move it to blobs.rs
