dc_configure() spawns a background configuration process.
It should increase the number of context references
so even if we unref the context, it is not dropped
until the end of the configuration process.
Currently running the test
with `pytest tests/test_1_online.py::test_configure_unref`
results in segmentation fault.
Previously we used tags like "1.109.0" and "py-1.109.0".
Since Python bindings are always released
at the same time as the core,
it is easier to use a single tag for them.
"v" prefix is added to make matching by "v*" easier
in CI and scripts.
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.
There was the following bug:
- Bob has two devices, the second is offline.
- Alice creates a verified group and sends a QR invitation to Bob.
- Bob joins the group.
- Bob's second devices goes online, but sees a contact request instead of the verified group.
- The "member added" message is not a system message but a plain text message.
- Sending a message fails as the key is missing -- message info says "proper enc-key for <Alice>
missing, cannot encrypt".
- Alice has two devices, the second is offline.
- Alice creates a verified group and sends a QR invitation to Bob.
- Bob joins the group and sends a message there. Alice sees it.
- Alice's second devices goes online, but doesn't see Bob in the group.
This allows to distinguish exceptions,
such as database errors, from invalid user input.
For example, if the From: field of the message
does not look like an email address, the mail
should be ignored. But if there is a database
failure while writing a new contact for the address,
this error should be bubbled up.
It's a w/a for "Space added before long group names after MIME serialization/deserialization"
issue. DC itself never creates group names with leading/trailing whitespace, so it can be safely
removed. On the sender side there's no trim() because group names anyway go through
improve_single_line_input(). And I believe we should send the exact name we have in our db. Also
there's no check for leading/trailing whitespace because there may be existing user databases with
group names having such whitespaces.
