this PR moves now advanced/unsupported ASM strings to core, removing
work from translations, esp. as another hint is added which would
require retranslations. it is better to have that just in english, it is
a nerd feature anyways.
moverover, this PR removes special rendering of ASM in the summary,
which might be confusion, but mainly it is now unneeded, dead code
i'll do another android PR that will point to "Add Second Device"
already on ASM generation EDIT: done at
https://github.com/deltachat/deltachat-android/pull/3726
targets https://github.com/deltachat/deltachat-desktop/issues/4946
When receiving messages, blobs will be deduplicated with the new
function `create_and_deduplicate_from_bytes()`. For sending files, this
adds a new function `set_file_and_deduplicate()` instead of
deduplicating by default.
This is for
https://github.com/deltachat/deltachat-core-rust/issues/6265; read the
issue description there for more details.
TODO:
- [x] Set files as read-only
- [x] Don't do a write when the file is already identical
- [x] The first 32 chars or so of the 64-character hash are enough. I
calculated that if 10b people (i.e. all of humanity) use DC, and each of
them has 200k distinct blob files (I have 4k in my day-to-day account),
and we used 20 chars, then the expected value for the number of name
collisions would be ~0.0002 (and the probability that there is a least
one name collision is lower than that) [^1]. I added 12 more characters
to be on the super safe side, but this wouldn't be necessary and I could
also make it 20 instead of 32.
- Not 100% sure whether that's necessary at all - it would mainly be
necessary if we might hit a length limit on some file systems (the
blobdir is usually sth like
`accounts/2ff9fc096d2f46b6832b24a1ed99c0d6/dc.db-blobs` (53 chars), plus
64 chars for the filename would be 117).
- [x] "touch" the files to prevent them from being deleted
- [x] TODOs in the code
For later PRs:
- Replace `BlobObject::create(…)` with
`BlobObject::create_and_deduplicate(…)` in order to deduplicate
everytime core creates a file
- Modify JsonRPC to deduplicate blob files
- Possibly rename BlobObject.name to BlobObject.file in order to prevent
confusion (because `name` usually means "user-visible-name", not "name
of the file on disk").

this PR adds the address to be used by the UI for
`window.webxdc.selfAddr` to webxdc-info. UIs need to be changed
accordingly and must not use configured_addr any longer.
the address is created by sha256(private-key + rfc724_mid) , which
results in different addresses for each webxdc, without the option to
find out the real address of the user.
this also returns the same address for a multi-device-setup - sending
totally random self address around might be an alternative, however
would require connectivity (both devices may be offline on first start).
for existing app, after the change, there will be a new user, resulting
eg. in a new highscore, otherwise, things should be mostly fine. this
assumption is also important as we might change the thing another time
when it comes to multi-transport.
ftr, addresses look like
`0f187e3f420748b03e3da76543e9a84ecff822687ce7e94f250c04c7c50398bc` now
when this is merged, we need to adapt #6230 and file issues for all UI
to use `info.selfAddr`
closes#6216
This is a hint for apps that a WebXDC icon should be shown in the summary, e.g. in the
chatlist. Otherwise it's not clear when it should be shown, e.g. it shouldn't be shown in a reaction
summary.
use get_summary_text_without_prefix() to get raw summaries without prefixes,
this is needed for reaction summaries,
where we also do not show the name, so we do not want to show "Forwarded" as well.
shows the last reaction in chatlist's summaries if there is no
newer message.
the reason to show reactions in the summary, is to make them a _little_
more visible when one is not in the chat. esp. in not-so-chatty or in
one-to-ones chats this becomes handy: imaging a question and someone
"answers" with "thumbs up" ...
otoh, reactions are still tuned down on purpose: no notifications, chats
are opend as usual, the chatlist is not sorted by reactions and also the
date in the summary refer to the last message - i thought quite a bit
about that, this seems to be good compromise and will raise the fewest
questions. it is somehow clear to the users that reactions are not the
same as a real message. also, it is comparable easy to implement - no
UI changes required :)
all that is very close to what whatsapp is doing (figured that out by
quite some testing ... to cite @adbenitez: if in doubt, we can blame
whatsapp :)
technically, i first wanted to go for the "big solution" and add two
more columns, chat_id and timestamp, however, it seemed a bit bloated if
we really only need the last one. therefore, i just added the last
reaction information to the chat's param, which seems more performant
but also easier to code :)
It can be used e.g. as a default in the file saving dialog. Also display the original filename in
the message info. For these purposes add Param::Filename in addition to Param::File and use it as an
attachment filename in sent emails.
Message.set_text() and Message.get_text() are modified accordingly
to accept String and return String.
Messages which previously contained None text
are now represented as messages with empty text.
Use Message.set_text("".to_string())
instead of Message.set_text(None).
this uses `get_webxdc_info().name` for chatlist etc.
the previuosly used static strings comes from a time
where we just did not had the correct name.
i was also thinking about adding `get_webxdc_info().summary`,
however, as this information is dynamic,
that may open several issues, eg. quoted text may change
so that the answer is out of context.
* 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.
