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
We had an unhelpful log in the Testing group:
- it repeatedly says "src/imap.rs:1010: dc_receive_imf error: add_parts error" but the actual error is not shown
- it says "deltachat-ffi/src/lib.rs:186: dc_get_config(): invalid key" but it doesn't say what key it's trying to set
ASCII armored keys can be easily generated with `sq key generate` and
used to encrypt and decrypt test messages with `sq` and `gpg` without
converting them to binary using `base64 -d` first.
* fix missing MX resolver eg. on android
switching completely to /etc/resolv.conf (see #2780)
does not work at least on some Androids
(see https://github.com/deltachat/deltachat-android/issues/2151 )
therefore, we use the old approach as a fallback.
* log a warning, when we again have problems with figuring out MX resolvers
* generate qr code svg prototype
* qr code for groups
fix formatting
* - letter avatar in qrcode
- escape xml in userinput (display/groupname)
- fix "Me" display name
- merge import declarations
* remove dot at the end of VerifyContactQRDescription
* if addr == displayname, show only one of them
Especially useful for yggmail accounts without usernames,
because the text would overflow otherwise.
* use real clipPath for rounded avatar
* - center avatar text better (dominant-baseline)
- add "sans-serif" to font fallback for text if arial is missing
* make corner always blue
* add [logo + "get.delta.chat"] footer to qrcode
* Update deltachat-ffi/deltachat.h

* new card design
- add stockstrings
- update changelog
* make qrcode pixels also #f2f2f2 instead of full white
* rename VERIFY_CONTACT_QR_DESC to SETUP_CONTACT
make footer text a tiny bit darker upon r10s's request
* avoid using which is a doxygen command
* point out that one will join a group (this is still shorted and was also suggested in recent chats)
* add option to generate qr-code-svg to repl tool
* use same font-family in text and footer
* thinner card border
* remove superfluous <tspan> from footer to make color tweaking easier
* move font-weight to style, ios renderer does not pick it up from attribute; remove default font attributes not used consequently
* make get.delta.chat more visible
* align properly using dominant-baseline=central and alignment-baseline=middle, this makes things nice on all systems but android (before, ios was wrong and all others not 100% aligned as font metrics are ignored) (android needs a subsequent improvement)

It was there since the C core, labeled with "/* last_seen is for
future use */" but never actually used. The comment was lost during
the translation from C to Rust.
* Add DC_EVENT_SELFAVATAR_CHANGED
* Add test.
Unfortunately I can't easily also test that the avatar is not copied
from unencrypted messages:
In the second encrypted message, the avatar would not be sent again
then, because we only send avatars once a day or so.

* add Chattype::Broadcast and create_broadcast_list()
* do not disclose recipients for broadcasts
* allow sending/add-/remove-member for broadcast
* set broadcast subject same as for one-to-one chats
* broadcast-recipient-list does not include SELF
* use special icon for broadcast groups
* generate initial broadcast names
* make clippy happy
* send BCC message unencrypted to avoid unexpected disclosing; encryption is opportunistic anyway. if we have 'protected chats' at some point, we can think that over.
* reword 'To:'-group
* simplify can-send-check
* add broadcast tests
* tweak comments
* Update deltachat-ffi/deltachat.h

summary::Summary replaces Lot in the Rust API for methods returning
chatlist summaries. Lot is a legacy type for C API compatibility, so
Summary can be converted into Lot.
Also make Accounts uncloneable. It is still possible to derive Clone,
but does not make sense to do so, as .clone() creates two separate
account managers which use the same files but different unsynchronized
in-memory data structures.
This adds following settings:
- Socks5Enabled
- Socks5Host
- Socks5Port
- Socks5User
- Socks5Password
Currently http requests and dns requests are not getting executed as they currently can't get tunneled through socks5 proxy. Therefore gmail with oauth2 wont work through tor.
Contact request chats are not merged into a single virtual "deaddrop"
chat anymore. Instead, they are shown in the chatlist the same way as
other chats, but sending of messages to them is not allowed and MDNs
are not sent automatically until the chat is "accepted" by the user.
New API:
- dc_chat_is_contact_request(): returns true if chat is a contact
request. In this case option to accept and block the chat via
dc_accept_chat() and dc_block_chat() should be shown in the UI.
- dc_accept_chat(): accept contact request and unblock the chat
- dc_block_chat(): decline contact request and block the chat
Removed API:
- dc_create_chat_by_msg_id(): deprecated 2021-02-07 in favor of
dc_decide_on_contact_request()
- dc_marknoticed_contact(): deprecated 2021-02-07 in favor of
dc_decide_on_contact_request()
- dc_decide_on_contact_request(): this call requires a message ID from
deaddrop chat as input. As deaddrop chat is removed, this call can't
be used anymore.
- dc_msg_get_real_chat_id(): use dc_msg_get_chat_id() instead, the
only difference between these calls was in handling of deaddrop chat
- removed DC_CHAT_ID_DEADDROP and DC_STR_DEADDROP constants
See https://support.delta.chat/t/discussion-how-to-show-error-states/1363/10 <!-- comment -->
It turns out that it's pretty easy to distinguish between lots of states (currently Error/NotConnected, Connecting…, Getting new messages… and Connected). What's not that easy is distinguishing between an actual error and no network, because if the server just doesn't respond, it could mean that we don't have network or that we are trying ipv6, but only ipv4 works.
**WRT debouncing:**
Sending of EVENT_CONNECTIVITY_CHANGED is not debounced, but emitted every time one of the 3 threads (Inbox, Mvbox and Sentbox) has a network error, starts fetching data, or is done fetching data.
This means that it is emitted:
- 9 times when dc_maybe_network() is called or we get network connection
- 12 times when we lose network connection
Some measurements: dc_get_connectivity() takes a little more than 1ms (in my measurements back in March), dc_get_connectivity_html() takes 10-20ms. This means that it's no immmediate problem to call them very often, might increase battery drain though. For the UI it may be a lot of work to update the title everytime; at least Android is smart enough to update the title only once.
Possible problems (we don't have to worry about them now I think):
- Due to the scan_folders feature, if the user has lots of folders, the state could be "Connecting..." for quite a long time, generally DC seemed a little unresponsive to me because it took so long for "Connecting..." to go away. Telegram has a state "Updating..." that sometimes comes after "Connecting...".
To be done in other PRs:
- Better handle the case that the password was changed on the server and authenticating fails, see https://github.com/deltachat/deltachat-core-rust/issues/1923 and https://github.com/deltachat/deltachat-core-rust/issues/1768
- maybe event debouncing (except for "Connected" connectivity events)
fix https://github.com/deltachat/deltachat-android/issues/1760
in most (all?) UIs, import/export works on an already created account,
so, dc_accounts_import_account() does not really help here -
but adds some noise and confusion
eg. as for the other dc_accounts_t functions,
the corrsponding dc_context_t functions must not be called.
if really a new account is required for import,
it seems to be easier to call add_account() before import.
Raw MIME messages may contain non-ASCII characters. Attempting to
store them as TEXT by using String::from_utf8_lossy results in
non-ASCII characters being replaced with Unicode U+FFFD "REPLACEMENT
CHARACTER" which is later incorrectly decoded when attempting to parse
`mime_headers` content into HTML.
New `dc_msg_is_bot()` C API and corresponding `Message.is_bot()`
Python API can be used to check if incoming message is sent by a bot,
e.g. to avoid two echo bots replying indefinitely to each other.
"Bot" flag is not set for outgoing messages, but may be set for
BCC-self messages. For now documentation says that `dc_msg_is_bot()`
return value is unspecified for outgoing messages. It can be better
specified later if needed for specific applications, e.g. sharing an
account with a helper bot.
Using `impl AsRef<str>` as the argument instead of `&str` makes it
possible to call the function with `&str`, `String` and other types
that implement `AsRef` trait.
The cost of it is that compiled binary contains mulitple versions of
the same function, one for each variant of types. If function contains
multiple generic `impl AsRef` arguments, the number of versions possibly
compiled into binary grows exponentially with the number of arguments.
Simple way to avoid it is to call `.as_ref()` on the caller side to
convert the argument to `&str`. In most cases even adding a `&` and
relying on `Deref` coercion is sufficient.
This patch changes many functions that accepted `impl AsRef<str>` and
`impl AsRef<Path>` to accept `&str` and `&Path` instead.
In some places `.clone()` calls are removed. Calling `.clone()` on
`String` and passing `String` to a function accepting `impl
AsRef<str>` is completely unnecessary as `&str` reference could be
passed instead. There is no clippy warning against it yet, but
changing argument type to `&str` allowed to find these cases.
The result of debloating is not impressive, several hundred kilobytes
are saved, which is about 3% of the `.so` binary, but the code is
cleaner too.
This moves the module-level lookup and creation functions to the
types, which make the naming more consistent. Now the lookup_* get_*
and create_* functions all behave similarly.
Peraps even more important the API of the lookup now allows
distinguishing failure from not found. This in turn is important to
be able to remove reliance on a ChatId with a 0 or "unset" value. The
locations where this ChatId(0) is still used is in database queries
which should be solved in an independed commit.
* Remove sql::error submodule
Use anyhow errors instead.
* Remove explicit checks for open SQL connection
An error will be thrown anyway during attempt to execute query.
* Don't use `with_conn()` and remove it
* Remove unused `with_conn_async`
* Resultify markseen_msgs
- Currently, group images are compressed as well because it was easier to implement that way.
- Currently, in the unlikely case that the avatar is compressed down to 20x20 pixels but still bigger than 20KB, the user doesn't get any indication of this, the avatar simply isn't changed (at least on Android).
If we want to change this, the easiest way is probably to let `dc_set_config()` in the ffi call `error!()` if `Selfavatar` can't be set. The same might make sense for some or all other configs. BUUUUUT: At least Android doesn't show error!() toasts anymore, probably because they were used too often and too spammy.
- The factor by which we scale down if the file is too big is 1.5.
Switches from rusqlite to sqlx to have a fully async based interface
to sqlite.
