* save webxdc-updates for not yet downloaded messages, that are probably webxdc instances then
* test webxdc updates received while instance is not yet downloaded
* keep msg_id on downloading messages
keeping msg_id on downloading messages
has the advantage that webxdc updates and other references to the msg_id
can be processed as usual.
if a message expands to multiple msg_id,
the last one is kept,
however, this does not affect webxdc at all.
(alternatives may be to update `msgs_status_updates`
but that seems more complicated and even less elegant,
another alternative would be to use different keys (eg. `rfc274_mid`),
but that also seems not to be much easier and would waste space as well.
also both alternatives would need adaption for other foreign keys)
* update CHANGELOG
* do not emit WebxdcStatusUpdate event in case the message is not yet downloaded
* move DELETE/UPDATE to an transaction
* make merge_msg_id() a little less confusing
* use some webxdc-update-param from placeholder
(the placeholder may be updated,
the just downloaded messages is not)
* more precise function name
* test not directly downloading status updates
* test not directly downloading mdn
* more flexible render_webxdc_status_update_object()
* delay webxdc updates when ratelimit is reached
* inject updates messages to the SMTP loop as needed
this avoids starting several tasks
and allows sending updates out after a restart of the app.
* use mutex to prevent race conditions in status updates
* check ratelimiter only before the sending loop; it won't change until messages are actually sent out
* fix typo
* prefer standard type declaration over turbofish syntax
* use UNIQUE and ON CONFLICT for query smtp_status_updates
* combine DELETE+SELECT to one atomic statement
* as all operations on smtp_status_updates are now atomic, a mutex is no longer needed
* test DELETE+RETURNING statement
* simplify calls to can_send()
* comment about ratelimit boolean in send_smtp_messages()
* clarify webxdc reference wrt info-messages
* add from_id parameter to add_info_msg_with_cmd()
* flag webxdc-info-messages as such
* set from_id to sender for webxdc-info-messages
* test additional webxdc info properties
* do not add series of similar info messages
instead, if on adding the last info message
is already from the same webxdc and sender,
just update the text
* test cleanup of webxdc info messages series
* update changelog
* make clippy happy
there is no real complexity in the args,
so allowing one more arg is probably fine.
if really wanted, we can refactor the function in another pr;
this pr is already complex enough :)
* use cleaner function names and comments
* clarify CHANGELOG
* do not wipe info for drafts
* drafts and received webxdc-instances, resent or not, do not trigger info-messages
* test that resending a webxdc does not not add legacy info-messages
* make clippy happy
* update CHANGELOG
bcc_self-updates are not received
due to the normal prevention of not even downloading these messages.
there is no extra defense of that on webxdc-level;
status-updates do not even have a "global-unique" id
(they have a local id and the message where they're wrappted into have the
"global-unique" Message-Id)
this bypasses the replication safety introduced by letting the caller track the last serial,
however, in case of bots that do not track much state and do not playback updates anyway,
it is still useful.
* add min_api to manifest.toml, define WEBXDC_API_VERSION
* return an error instead of index.html if the webxdc requires a newer api
* add a test with an webxdc requiring a newer api
* update CHANGELOG
This seems not only wasteful but genuinly has the risk someone makes
their device useless by accidentally adding a huge file.
This also re-structures the checks a little: The if-conditions are
flattened out and cheap checks are done before more expensive ones.
* (r10s, adb, hpk) remove getAllUpdates() and add a typical replica-API that works with increasing serials. Streamline docs a bit.
* adapt ffi to new api
* documentation: updates serials may have gaps
* get_webxdc_status_updates() return updates larger than a given serial
* remove status_update_id from status-update-event; it is not needed (ui should update from the last known serial) and easily gets confused with last_serial
* unify wording to 'StatusUpdateSerial'
* remove legacy payload format, all known webxdc should be adapted
* add serial and max_serial to status updates
* avoid races when getting max_serial by avoiding two SQL calls
* update changelog

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.
as discussed in dev chat,
100 kb is too low if one wants to use any game framework.
also, many game that doesn't have poor graphics
or uses magic CSS-tricks to do fancy draws,
will have more than 100 kb probably just in tiles and sprites.
even for regions with low resources,
100 kb is low for a game -
esp. if we compare that with stickers that are send around as well
are not deduplicated and also have several 100 kb in size -
for much less effect.
we should still encourage ppl to create tiny apps,
however, a too low limit also restricts possibilities wrt adaption.
already before,
we did _not_ sent updates to contact requests or other read-only-chats.
however, we _did_ modify the local database,
so that getAllUpdates() returns an update that was not sent out to other peers.
this is fixed by checking can_send() soon.
that way, all peers have the same state
also for contact requests or other read-only-chats
and webxdc in contact requests can be opened as usual.
further ui improvements may be needed for contact requests
(maybe allow the webxdc to know about that state or
maybe show a warning in the ui somewhere),
however, this is not part of this pr.
* let sending invalid webxdc fail
invalid webxdc can still be send as Viewtype::File, however
(maybe one want to discuss errors or so ;)
* clarify the supported zip compression methods
* add a test for unencrypted replies to encrypted webxdc instances
* make update messages work if a key is missing
even in opportunistic chats,
replies to encrypted messages are forced to be encrypted,
if that is not possbile, message sending fails.
while this is okay to not leak previously send text messages,
the quotes as used by webxdc are more artificial,
currently only the static text "Webxdc".
* changelog ...
* fix forwarding webxdc instances, add a test for that
* adapt webxdc test to fail on info-messages added when in draft mode
* do not add info-messages when in draft-mode
* half the number of instance-loads per webxdc update send/receive
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.
