BridgeMessage is a type of chat message content which will be sent from Matterbridge.
It contains fields:
- bridge name - depends on the used bridge, eg. "discord", "slack", etc...
- user name - username the message was received from
- content - message content
- user avatar
- message id
- parent message id - used in case of replies
Message is saved to a separated table: bridge_messages, similarly to discord messages.
The user_messages table is untouched.
bridge_messages table contains user_messages_id in order to join with user_messages table.
Issue #13098
This PR fixes [9947](status-im/status-desktop#9947) and contains :
- Commit to fix the changing of custom picture and having the change
reflected on contact's side
- Commit to fix the deleting of picture and having the change reflected
on contact's side
- Rename confusing `ImageType` to `ImageFormat`
This commit adds a test for out of order messages, which were only
implicitly tested.
It also deletes them after being processed, otherwise they would be
reproceessed each time a message was sent
This commit changes the format of the encryption id to be based off 3
things:
1) The group id
2) The timestamp
3) The actual key
Previously this was solely based on the timestamp and the group id, but
this might lead to conflicts. Moreover the format of the key was an
uint32 and so it would wrap periodically.
The migration is a bit tricky, so first we cleared the cache of keys,
that's easier than migrating, and second we set the new field hash_id to
the concatenation of group_id / key_id.
This might lead on some duplication in case keys are re-received, but it
should not have an impact on the correctness of the code.
I have added 2 tests covering compatibility between old/new clients, as
this should not be a breaking change.
It also adds a new message to rekey in a single go, instead of having to
send multiple messages
- use `appdatabse.DbInitializer{}` in tests to ensure consistent migrations
- remove protocol's open database functions due to improper
initialization caused by missing node config migration
- introduce `PushNotificationServerConfig` to resolve cyclic dependency
issues
This commit adds support for unfurling static image URLs (not GIFs, not animated WebPs), such as https://placehold.co/600x400@2x.png. It also compresses images before returning them as data URIs to clients.
About compression: the compression strategy leverages the existing function images.CompressToFileLimits. A more comprehensive logic to consider the possibility of multiple image URLs being unfurled simultaneously is yet to be implemented.
Closes#3761
Sometimes confirmation for raw messages are received before the record
is actually saved in the database.
In this case, the code will preserve the Sent status.
This is the initial implementation for the new URL unfurling requirements. The
most important one is that only the message sender will pay the privacy cost for
unfurling and extracting metadata from websites. Once the message is sent, the
unfurled data will be stored at the protocol level and receivers will just
profit and happily decode the metadata to render it.
Further development of this URL unfurling capability will be mostly guided by
issues created on clients. For the moment in status-mobile:

### Terminology
In the code, I've tried to stick to the word "unfurl URL" to really mean the
process of extracting metadata from a website, sort of lower level. I use "link
preview" to mean a higher level structure which is enriched by unfurled data.
"link preview" is also how designers refer to it.
### User flows
1. Carol needs to see link previews while typing in the chat input field. Notice
from the diagram nothing is persisted and that status-go endpoints are
essentially stateless.

2. Carol sends the text message with link previews in the RPC request
wakuext_sendChatMessages. status-go assumes the link previews are good
because it can't and shouldn't attempt to re-unfurl them.
```
#+begin_src plantuml :results verbatim

3. The message was sent over waku and persisted locally in Carol's device. She
should now see the link previews in the chat history. There can be many link
previews shared by other chat members, therefore it is important to serve the
assets via the media server to avoid overloading the ReactNative bridge with
lots of big JSON payloads containing base64 encoded data URIs (maybe this
concern is meaningless for desktop). When a client is rendering messages with
link previews, they will have the field linkPreviews, and the thumbnail URL
will point to the local media server.
```
#+begin_src plantuml :results verbatim

### Some limitations of the current implementation
The following points will become separate issues in status-go that I'll work on
over the next couple weeks. In no order of importance:
- Improve how multiple links are fetched; retries on failure and testing how
unfurling behaves around the timeout limits (deterministically, not by making
real HTTP calls as I did). https://github.com/status-im/status-go/issues/3498
- Unfurl favicons and store them in the protobuf too.
- For this PR, I added unfurling support only for websites with OpenGraph
https://ogp.me/ meta tags. Other unfurlers will be implemented on demand. The
next one will probably be for oEmbed https://oembed.com/, the protocol
supported by YouTube, for example.
- Resize and/or compress thumbnails (and favicons). Often times, thumbnails are
huge for the purposes of link previews. There is already support for
compressing JPEGs in status-go, but I prefer to work with compression in a
separate PR because I'd like to also solve the problem for PNGs (probably
convert them to JPEGs, plus compress them). This would be a safe choice for
thumbnails, favicons not so much because transparency is desirable.
- Editing messages is not yet supported.
- I haven't coded any artificial limit on the number of previews or on the size
of the thumbnail payload. This will be done in a separate issue. I have heard
the ideal solution may be to split messages into smaller chunks of ~125 KiB
because of libp2p, but that might be too complicated at this stage of the
product (?).
- Link preview deletion.
- For the moment, OpenGraph metadata is extracted by requesting data for the
English language (and fallback to whatever is available). In the future, we'll
want to unfurl by respecting the user's local device language. Some websites,
like GoDaddy, are already localized based on the device's IP, but many aren't.
- The website's description text should be limited by a certain number of
characters, especially because it's outside our control. Exactly how much has
not been decided yet, so it'll be done separately.
- URL normalization can be tricky, so I implemented only the basics to help with
caching. For example, the url https://status.im and HTTPS://status.im are
considered identical. Also, a URL is considered valid for unfurling if its TLD
exists according to publicsuffix.EffectiveTLDPlusOne. This was essential,
otherwise the default Go url.Parse approach would consider many invalid URLs
valid, and thus the server would waste resources trying to unfurl the
unfurleable.
### Other requirements
- If the message is edited, the link previews should reflect the edited text,
not the original one. This has been aligned with the design team as well.
- If the website's thumbnail or the favicon can't be fetched, just ignore them.
The only mandatory piece of metadata is the website's title and URL.
- Link previews in clients should be generated in near real-time, that is, as
the user types, previews are updated. In mobile this performs very well, and
it's what other clients like WhatsApp, Telegram, and Facebook do.
### Decisions
- While the user typing in the input field, the client is constantly (debounced)
asking status-go to parse the text and extract normalized URLs and then the
client checks if they're already in its in-memory cache. If they are, no RPC
call is made. I chose this approach to achieve the best possible performance
in mobile and avoid the whole RPC overhead, since the chat experience is
already not smooth enough. The mobile client uses URLs as cache keys in a
hashmap, i.e. if the key is present, it means the preview is readily available
(naive, but good enough for now). This decision also gave me more flexibility
to find the best UX at this stage of the feature.
- Due to the requirement that users should be able to see independent loading
indicators for each link preview, when status-go can't unfurl a URL, it
doesn't return it in the response.
- As an initial implementation, I added the BLOB column unfurled_links to the
user_messages table. The preview data is then serialized as JSON before being
stored in this column. I felt that creating a separate table and the related
code for this initial PR would be inconvenient. Is that reasonable to you?
Once things stabilize I can create a proper table if we want to avoid this
kind of solution with serialized columns.
Adds a new column named `deleted` to the table `activity_center_notifications`.
Related PR in Mobile https://github.com/status-im/status-mobile/pull/15106 for a lot more details of the feature.
Why? Relying on the `dismissed` column for soft deletion is no longer viable because the mobile & desktop clients should display dismissed notifications (sometimes), hence the need for a new column to truly represent soft deletion.

Summary
=======
- [x] Changes endpoint ActivityCenterNotificationsBy to support fetching
multiple types of notification in a single query.
- [x] Adds endpoint UnreadAndAcceptedActivityCenterNotificationsCount to
allow the mobile client to fetch the count of unread & accepted
notifications.
- [x] Add `golangci-lint` to Nix shell. This was possible since PR
https://github.com/status-im/status-go/pull/3087 was merged.
Notes
=====
- If you'd like to understand why these changes are needed, please see
the mobile PR https://github.com/status-im/status-mobile/pull/14785,
or issue https://github.com/status-im/status-mobile/issues/14712
- All changes should be completely backwards compatible, and there
should be no impact for the desktop app.
- The mobile client has been already tested using this branch.
This creates a smoother experience for users when they leave a community since they can see the exact same messages they had before without having to rely on the mailserver.
This adds a new `DiscordMessageAttachment` type which is part of
`DiscordMessage`. Along with that type, there's also a new database
table for `discord_message_attachments` and corresponding persistence
APIs.
This commit also changes how chat messages are retrieved.
Here's why:
`DiscordMessage` can have multiple `DiscordMessageAttachment`.
A chat message can have a `DiscordMessage`.
Because we're `LEFT JOIN`'ing the discord message attachments into the
chat messages, there's a possibility of multiple rows per message.
Hence, this commit ensures we collect queried discord message
attachments on chat messages.
`FirstMessageTimestamp` enables members of the community to determine if
there are any messages they can fetch on the community channel(chat).
`FirstMessageTimestamp` is advertised by admin for each community chat
through `CommunityDescription`. It assumes admin is online frequently
enough to capture the first channel message.
For existing communities admin determines first message timestamp by
finding oldest chat message in its local database.
task: status-im/status-desktop#6731
This adds a new `discord_messages` table and extends the persistence
APIs such that `MessagesByID` and `MessageByID` will return user
messages that include their discord message payload.
It also adds APIs to save individual discord messages.
This introduces a new table to store discord message authors.
The main reason this table is being introduce is so that we don't have
to duplicate discord message author information in the `user_messages`
table when importing discord communities (ongoing work).
In addition to the table there are also two new APIs on the messenger
persistence layer (which are later used in the import logic):
- `HasDiscordMessageAuthor`
- `SaveDiscordMessageAuthor`
Closes#2759
* add PinMessage and PinnedMessage
* fix gruop pin messages
* add SkipGroupMessageWrap to pin messages
* update pinMessage ID generation to be symmetric
This commit expands the confirmation mechanism to allow private group
chat messages to be confirmed:
Changes:
- Added a separate table for message confirmations as group chat
messages have same messageID but multiple datasyncID
- Removed DataSyncID from raw message (I haven't removed the column name
as it can't be done in sqlite without copying over the table)
