To create encrypted account with account manager, call
dc_accounts_add_closed_account(). Open this account with
dc_context_open() using the passphrase you want to use for encryption.
When application is loaded next time and account manager is created,
it will open all accounts that have no passphrase set. For encrypted
accounts dc_context_is_open() will return 0. To open them, call
dc_context_open() with the correct passphrase. After opening, call
dc_context_start_io() on this account or just dc_accounts_start_io()
to start all accounts that are not started yet.
Support for legacy SQLite-based backup format is removed in this
commit.
- Replace .ok_or_else() and .map_err() with anyhow::Context where possible.
- Use .context() to check Option for None when it's an error
- Resultify Chatlist.get_chat_id()
- Add useful .context() to some errors
- IMAP error handling cleanup
Seen status is only synchronized on servers supporting IMAP CONDSTORE
extension. At the end of fetch loop iteration, flags are fetched for
all messages modified since previous synchronization and highest
modification sequence is stored into `imap_sync` table.
It slows down dc_get_chat_msgs() from ~50ms to seconds on Android. It
is disabled by default in SQLCipher 4.5.0, but currently SQLCipher 4.4.3
is bundled so this PRAGMA has to be disabled manually.
This is an irrecoverable error, dc_receive_imf must not fail on it
as it prevents last seen UID from advancing, so the same message
is prefetched on each iteration of IMAP loop.
the summary can be modified by the apps using
`sendUpdate({summary: "foo", payload: ...})`
the summary is updated when there is no newer update
and chat will be informed by the change as usual by
`DC_EVENT_MSGS_CHANGED`.
additional parameters will be `summary` and `msg` (for an info-message)
right now, and maybe more in the future (`aggregated`, `fast`, `to` ...),
so adding just more parameters easily gets wild.
also, this makes adaptions easier as no ffi needs to be adapted
when we add more parameters.
finally, sending is in-sync with receiving, database and wire now,
one receives similar objects as one sends,
which also looks like the right thing :)
for now, `sendUpdate()` also allows to use the old, unwrapped payload
to not immediately break existing `.xdc`, however, that will be removed soon,
probably before the first release.
Previously default of `auto_vacuum=NONE` was used.
`PRAGMA auto_vacuum=INCERMENTAL` allows running `PRAGMA
incremental_vacuum`. Unlike `VACUUM`, `PRAGMA incremental_vacuum`
frees unused pages without rebuilding the whole database, like the
`VACUUM` does, so it does not require additional disk space to build a
vacuumed copy of the database. This may even free enough space on the
disk to run `VACUUM` afterwards.
New setting will only be enabled for new databases or if the `VACUUM`
command runs successfully. Currently `VACUUM` is only executed on
backup export, but may fail nevertheless if there is not enough space
on the disk.
Also try to run `PRAGMA incremental_vacuum` during housekeeping. It
may not be the best strategy, but likely does not make any difference
under normal usage when the database only grows and there are no free
pages. Free pages are created only if enough data is deleted to free
at least one database page of 4096 bytes, for example when automatic
deletion of messages is deleted for the first time. In the future if
more data is placed into the database, like avatars and other blobs,
it may be necessary to revise this strategy, for example to keep some
free pages instead of removing all of them each time by querying
`PRAGMA freelist_pages` and running `PRAGMA incremental_vacuum(N)`.
Also resultified `get_watched_folders`.
Python test `test_moved_markseen` is modified to test using incoming
message instead of BCC-self message, because BCC-self message is
detected immediately in the Inbox.
