The webxdc file name itself isn't informative for users. Still, send and display it if the webxdc
manifest can't be parsed, it's better than sending "Mini App" and this isn't a normal case anyway.
Iroh-Gossip-Topic is sent in a post-message. Post-message goes to trash,
so topic should be associated with the existing pre-message that is
updated rather than with the post-message.
with this PR, when an `.xdc` with `request_integration = map` in the
manifest is added to the "Saved Messages" chat, it is used _locally_ as
an replacement for the shipped maps.xdc (other devices will see the
`.xdc` but not use it)
this allows easy development and adapting the map to use services that
work better in some area.
there are lots of known discussions and ideas about adding more barriers
of safety. however, after internal discussions, we decided to move
forward and also to allow internet, if requested by an integration (as
discussed at
https://github.com/deltachat/deltachat-core-rust/pull/3516).
the gist is to ease development and to make users who want to adapt,
actionable _now_, without making things too hard and adding too high
barriers or stressing our own resources/power too much.
note, that things are still experimental and will be the next time -
without the corresponding switch being enabled, nothing will work at
all, so we can be quite relaxed here :)
for android/ios, things will work directly. for desktop, allow_internet
needs to be accepted unconditionally from core. for the future, we might
add a question before using an integration and/or add signing. or sth.
completely different - but for now, the thing is to get started.
nb: "integration" field in the webxdc-info is experimental as well and
should not be used in UIs at all currently, it may vanish again and is
there mainly for simplicity of the code; therefore, no need to document
that.
successor of https://github.com/deltachat/deltachat-core-rust/pull/5461
this is how it looks like currently - again, please note that all that
is an experiment!

... when going out of experimental, there are loots of ideas, eg.
changing "Start" to "integrate"
as discussed in several chats, this PR starts making it possible to use
Webxdc as integrations to the main app. In other word: selected parts of
the main app can be integrated as Webxdc, eg. Maps [^1]
this PR contains two parts:
- draft an Webxdc Integration API
- use the Webxdc Integration API to create a Maps Integration
to be clear: a Webxdc is not part of this PR. the PR is about marking a
Webxdc being used as a Map - and core then feeds the Webxdc with
location data. from the view of the Webxdc, the normal
`sendUpdate()`/`setUpdateListener()` is used.
things are still marked as "experimental", idea is to get that in to
allow @adbenitez and @nicodh to move forward on the integrations into
android and desktop, as well as improving the maps.xdc itself.
good news is that we currently can change the protocol between Webxdc
and core at any point :)
# Webxdc Integration API
see `dc_init_webxdc_integration()` in `deltachat.h` for overview and
documentation.
rust code is mostly in `webxdc/integration.rs` that is called by other
places as needed. current [user of the API is
deltachat-ios](https://github.com/deltachat/deltachat-ios/pull/1912),
android/desktop will probably follow.
the jsonrpc part is missing and can come in another PR when things are
settled and desktop is really starting [^2] (so we won't need to do all
iterations twice :) makes also sense, when this is done by someone
actually trying that out on desktop
while the API is prepared to allow other types of integrations (photo
editor, compose tools ...) internally, we currently ignore the type. if
that gets more crazy, we probably also need a dedicated table for the
integrations and not just a single param.
# Maps Integration
rust code is mostly in `webxdc/maps_integration.rs` that is called by
`webxdc/integration.rs` as needed.
EDIT: the idea of having a split here, is that
`webxdc/maps_integration.rs` really can focus on the json part, on the
communication with the .xdc, including tests
this PR is basic implementation, enabling to move forward on
integrations on iOS, but also on desktop and android.
the current implementation allows already the following:
- global and per-chat maps
- add and display POIs
- show positions and tracks of the last 24 hours
the current maps.xdc uses leaflet, and is in some regards better than
the current android/desktop implementations (much faster, show age of
positions, fade out positions, always show names of POIs, clearer UI).
however, we are also not bound to leaflet, it can be anything
> [**screenshots of the current
state**](https://github.com/deltachat/deltachat-ios/pull/1912)
> 👆
to move forward faster and to keep this PR small, the following will go
to a subsequent PR:
- consider allowing webxdc to use a different timewindow for the
location
- delete POIs
- jsonrpc
[^1]: maps are a good example as anyways barely native (see android
app), did cause a lot of pain on many levels in the past (technically,
bureaucratically), and have a comparable simple api
[^2]: only going for jsonrpc would only make sense if large parts of
android/ios would use jsonrpc, we're not there

* add request_internet_access manifest option
* test request_internet_access
* update CHANGELOG
* force warning when internet access is enabled
if internet access is enabled,
show a warning instead of the normal summary
(the internet access is currently mainly to test out integrations
as maps for video chat; the summary is dispensable in the cases currently)
* adapt json-rpc's WebxdcMessageInfo
* 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
* 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
