This adds a new `DownloadingHistoryArchivesFinished` signal to the
family of community archive signals. It's emitted when all to be
downloaded archives have been downloaded and handled.
Remove Favourites APIs and update the saved address APIs
Added up migration scripts that move the favourites from the old table
to the saved_addresses table with true flag and then drop the favourites table.
Required by #6546
`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.

As part of the new Discord <-> Status Community Import functionality,
we're adding an API that extracts all discord categories and channels
from a previously exported discord export file.
These APIs can be used in clients to show the user what categories and
channels will be imported later on.
There are two APIs:
1. `Messenger.ExtractDiscordCategoriesAndChannels(filesToimport
[]string) (*MessengerResponse, map[string]*discord.ImportError)`
This takes a list of exported discord export (JSON) files (typically one per
channel), reads them, and extracts the categories and channels into
dedicated data structures (`[]DiscordChannel` and `[]DiscordCategory`)
It also returns the oldest message timestamp found in all extracted
channels.
The API is synchronous and returns the extracted data as
a `*MessengerResponse`. This allows to make the API available
status-go's RPC interface.
The error case is a `map[string]*discord.ImportError` where each key
is a file path of a JSON file that we tried to extract data from, and
the value a `discord.ImportError` which holds an error message and an
error code, allowing for distinguishing between "critical" errors and
"non-critical" errors.
2. `Messenger.RequestExtractDiscordCategoriesAndChannels(filesToImport
[]string)`
This is the asynchronous counterpart to
`ExtractDiscordCategoriesAndChannels`. The reason this API has been
added is because discord servers can have a lot of message and
channel data, which causes `ExtractDiscordCategoriesAndChannels` to
block the thread for too long, making apps potentially feel like they
are stuck.
This API runs inside a go routine, eventually calls
`ExtractDiscordCategoriesAndChannels`, and then emits a newly
introduced `DiscordCategoriesAndChannelsExtractedSignal` that clients
can react to.
Failure of extraction has to be determined by the
`discord.ImportErrors` emitted by the signal.
**A note about exported discord history files**
We expect users to export their discord histories via the
[DiscordChatExporter](https://github.com/Tyrrrz/DiscordChatExporter/wiki/GUI%2C-CLI-and-Formats-explained#exportguild)
tool. The tool allows to export the data in different formats, such as
JSON, HTML and CSV.
We expect users to have their data exported as JSON.
Closes: https://github.com/status-im/status-desktop/issues/6690
This introduces a flag to configure whether `Messenger.CreateCommunity`
should create a default channel.
As discussed in https://github.com/status-im/status-go/issues/2758, this
is needed for the upcoming functionality to import discord communities.

This introduces a simple garbage collection which checks for all soft
deleted bookmarks (`removed = 1`) which have been marked for garbage
collection more than 30 days ago from the time of bootstapping the
messenger.
Closes#2705
These APIs are being introduced to address #2706 and #2704, provided
that clients will move to using these APIs instead of the currently
provided equivalent APIs in the browser service.
The `bookmarks` table is being extended with a `deleted_at` field which
can later be used for garbage collection, as "removing" a bookmark is
merely soft deletion and doesn't actually remove the data from the
database.
In addition to those APIs adding and soft deleting bookmark entries,
they also automatically perform a sync operation to ensure that
bookmarks are synced in real-time (#2704).
Closes#2706, #2704

Added functionality to find target address when 6th param in path is added
for ex: "m'/44'/60'/0'/0/500" reperents the Address at the 500th index
Added a api to get the Address derived from a private key
This introduces logic needed to:

These are used to store settings for individual communities a
user is part of, either as member or as owner.
This included whether or not the community history archive protocol
is enabled.
This adds a new `CommunitySettings` type and adds
a migration script that introduces a new `communities_settings`
table.
It also extends the `MessengerResponse` type to include
`CommunitySettings` which are honored when communities are being
added, edited, joined or left.
Lastly, this adds a new RPC API to retreive the settings.
Closes#2564
This commit introduces a new `TorrentConfig` as per #2563 with dedicated
default values and new options/flags for the status-go CLI.
Since it's part of `NodeConfig`, which is stored per user in the
database, this commit also adds a migration script that adds a new
`torrent_config` table and database APIs to insert and retreive the
torrent config.
Closes#2563
This commit enables mailserver cycle logic by default and make a few
changes:
1) Nodes are graylisted instead of being blacklisted for a set amount of
time. The reason is that if we blacklist, any cut in connectivity
might result in long delays before reconnecting, especially on spotty
connections.
2) Fixes an issue on the devp2p server, whereby the node would not
connect to one of the static nodes since all the connection slots
where filled. The fix is a bit inelegant, it always connects to
static nodes, ignoring maxpeers, but it's tricky to get it to work
since the code is clearly not written to select a specific node.
3) Adds support to pinned mailservers
4) Add retries to mailservers requests. It uses a closure for now, I
think we should eventually have a channel etc, but I'd leave that for
later.
We periodically check whether we should backup contacts through waku.
Currently it's not tied to any event, it will only schedule a backup on
a tick, or through the provided API endpoint.

Allow Communities to be edited, including display name, description, color, membership, and permissions.
* Added EditCommunity request type
* Fix lint errors
* Allow editing community without changing image
Previously, retaining an existing community image was not possible because the existing community image path had to be provided in the `editCommunity` RPC call to retain the image. However, once the image is processed by status-go, it is encoded as a base64 string and therefore it is not possible to get the original file path back from this string.
This commit allows for the original to be retained by passing an empty string for the image field in the RPC call.

- avoid making RPC request for `zero - zero` range
- avoid checking of nonce for a lower block in the range if it is zero
in a higher block
- on `wallet_getTransfersByAddress` scanning of history is skipped if
zero block is already reached
- no need to fetch block num before fetching token balances
- old existing ranges are merged when wallet service is started
- a new range is merged with an existing one if possible
This will decrease the number of entries in blocks_range table as
currently it can grow indefinitely (@flexsurfer reported 23307 entries).
This change is also needed for further optimisations of RPC usage.
There was a bug on status-react where it would save filters that were
not listened to.
This commit adds a task to clean up those filters as they might result
in long syncing times.
This commit also returns topics/ranges/mailserves from messenger in
order to make the initialization of the app simpler and start moving
logic to status-go.
It also removes whisper from vendor.
* Initial work on expanding Local Notifications
Adding functionality to support multiple notification types in Notification.Body. Currently have a bug that I think is caused by a the jsonMarshal func not working as intented, need to resolve this next before proceeding

* Tweak errors, go convention is errors don't begin with capital letters
* Added notificationMessageBody with un/marshalling
Also removed the Body interface

* Refactor to remove cycle imports
* Resolved linting issue ... Hopefully
* Resolving an implicit memory aliasing in a for loop

There was an issue in using the `Wallet` flag when checking accounts to
watch for transactions.
`Wallet` indicates that it's the default wallet, not whether is a wallet
account.
That can only be checked by looking at the type (and the `Wallet` flag).
If the type is `generated`, `key` or `seed` it should be watched for
transactions.
This commit adds an endpoint to batch the sending of messages.
This is useful to simplify client logic when sending a batch of messages
and ensuring the correct order in the message stream.
It currently implements only what's needed, and naively return an error
if any of the messages fail.
We were not actually passing the topics in the request, therefore we
were using bloom filter for query, which resulted in long syncing times
for some users.
- Wallet service is not started on foreground event on status-go side
anymore, it leaves a client side opportunity to decide whether new
blocks should be watched.
- `watchNewBlocks` parameter is added to `StartWallet`.
- Some requests are removed/moved to the place where they are necessary.
If one request failed, the whole batch would fail.
This caused issue as one of the contract is constantly returning an
error now, and essentially there was not way to fetch balance.
Also extend the timeout to 20s as we throw 165 request to Infura in one
go and it takes its time to reply to those, although it seems like we
should batch them on our side instead of sending them all cuncurrently.
For some reason when calling saveChat from desktop with `lastMessage`
set to null, a sigsev is received.
The issue seems to be in logFormat
05280a7ae3/log/format.go (L356)
which for some reason blows up if passed a nil pointer (`lastMessage`).
Can't replicate on any other platform or running it locally, but hey,
this fixes the issue.
StartWallet was called before service initialization.
After the recent changes this call was moved after initialization, but
the geth system automatically start services.
This meant that `IsStarted()` returned true, although the reactor was
not started, and only after calling `StopWallet()` and `StartWallet()`
again the system would reach the right state.
This commit changes the behavior so that we only check whether the
reactor has been started when calling `IsStarted()` and we allow
multiple calls to `Start()` on the signal service, which won't return an
error (it's a noop if callled multiple times).
Incentivisation was an experiment in running an incentivised fleet that
rewarded nodes based on their well behavior. It was heavily influenced
by https://docs.loki.network/ . It is currently not used anymore, so
removing.

Why make the change?
As discussed previously, the way we will move across versions is to maintain completely separate
codebases and eventually remove those that are not supported anymore.
This has the drawback of some code duplication, but the advantage is that is more
explicit what each version requires, and changes in one version will not
impact the other, so we won't pile up backward compatible code.
This is the same strategy used by `whisper` in go ethereum and is influenced by
https://www.youtube.com/watch?v=oyLBGkS5ICk .
All the code that is used for the networking protocol is now under `v0/`.
Some of the common parts might still be refactored out.
The main namespace `waku` deals with `host`->`waku` interactions (through RPC),
while `v0` deals with `waku`->`remote-waku` interactions.
In order to support `v1`, the namespace `v0` will be copied over, and changed to
support `v1`. Once `v0` will be not used anymore, the whole namespace will be removed.
This PR does not actually implement `v1`, I'd rather get things looked over to
make sure the structure is what we would like before implementing the changes.
What has changed?
- Moved all code for the common parts under `waku/common/` namespace
- Moved code used for bloomfilters in `waku/common/bloomfilter.go`
- Removed all version specific code from `waku/common/const` (`ProtocolVersion`, status-codes etc)
- Added interfaces for `WakuHost` and `Peer` under `waku/common/protocol.go`
Things still to do
Some tests in `waku/` are still testing by stubbing components of a particular version (`v0`).
I started moving those tests to instead of stubbing using the actual component, which increases
the testing surface. Some other tests that can't be easily ported should be likely moved under
`v0` instead. Ideally no version specif code should be exported from a version namespace (for
example the various codes, as those might change across versions). But this will be a work-in-progress.
Some code that will be common in `v0`/`v1` could still be extract to avoid duplication, and duplicated only
when implementations diverge across versions.
This resolves a dependency conflict we have with MatterBridge
which was using a newer version of the same package.
This resulted in a JSON marshalling bug that would crash the bridge.

- unused API methods are removed
- some unusued code is removed too
- API docs are updated
That's just a portion of clean up that should be done,
but the rest of it will probably happen in different PR
with changes to the way how we watch to chain updates.
Currently ENS are verified explicitly by status-react, this is not ideal
as if that fails it will have to be explicilty retried in status-react.
This commits changes that behavior so that ENS are verified in a loop
and updated if new messages are received.
- In order to avoid handling of the reorganized blocks we use an offset
from the latest known block when start listening to new blocks. Before
this commit the offset was 15 blocks for all networks. This offset is
too big for mainnet and causes noticeable delay of marking a transfer as
confirmed in Status (comparing to etherscan). So it was changed to be 5
blocks on mainnet and is still 15 blocks on other networks.
- Also before this commit all new blocks were handled one by one with
network specific interval (10s for mainnet), which means that in case of
lost internet connection or application suspension (happens on iOS)
receiving of new blocks would be paused and then resumed with the same
"speed" - 1 blocks per 10s. In case if that pause is big enough the
application would never catch up with the latest block in the network,
and this also causes the state of transfers to be delayed in the
application. In this commit in case if there was more than 40s delay
after receiving of the previous block the whole history in range between
the previous received block and ("latest"-reorgeSafetyDepth) block is
checked at once and app catches up with a recent state of the chain.
*** How it worked before this PR on multiaccount creation:
- On multiacc creation we scanned chain for eth and erc20 transfers. For
each address of a new empty multiaccount this scan required
1. two `eth_getBalance` requests to find out that there is no any
balance change between zero and the last block, for eth transfers
2. and `chain-size/100000` (currently ~100) `eth_getLogs` requests,
for erc20 transfers
- For some reason we scanned an address of the chat account as well, and
also accounts were not deduplicated. So even for an empty multiacc we
scanned chain twice for each chat and main wallet addresses, in result
app had to execute about 400 requests.
- As mentioned above, `eth_getBalance` requests were used to check if
there were any eth transfers, and that caused empty history in case
if user already used all available eth (so that both zero and latest
blocks show 0 eth for an address). There might have been transactions
but we wouldn't fetch/show them.
- There was no upper limit for the number of rpc requests during the
scan, so it could require indefinite number of requests; the scanning
algorithm was written so that we persisted the whole history of
transactions or tried to scan form the beginning again in case of
failure, giving up only after 10 minutes of failures. In result
addresses with sufficient number of transactions would never be fully
scanned and during these 10 minutes app could use gigabytes of
internet data.
- Failures were caused by `eth_getBlockByNumber`/`eth_getBlockByHash`
requests. These requests return significantly bigger responses than
`eth_getBalance`/`eth_transactionsCount` and it is likely that
execution of thousands of them in parallel caused failures for
accounts with hundreds of transactions. Even for an account with 12k
we could successfully determine blocks with transaction in a few
minutes using `eth_getBalance` requests, but `eth_getBlock...`
couldn't be processed for this acc.
- There was no caching for for `eth_getBalance` requests, and this
caused in average 3-4 times more such requests than is needed.
*** How it works now on multiaccount creation:
- On multiacc creation we scan chain for last ~30 eth transactions and
then check erc20 in the range where these eth transactions were found.
For an empty address in multiacc this means:
1. two `eth_getBalance` transactions to determine that there was no
balance change between zero and the last block; two
`eth_transactionsCount` requests to determine there are no outgoing
transactions for this address; total 4 requests for eth transfers
2. 20 `eth_getLogs` for erc20 transfers. This number can be lowered,
but that's not a big deal
- Deduplication of addresses is added and also we don't scan chat
account, so a new multiacc requires ~25 (we also request latest block
number and probably execute a few other calls) request to determine
that multiacc is empty (comparing to ~400 before)
- In case if address contains transactions we:
1. determine the range which contains 20-25 outgoing eth/erc20
transactions. This usually requires up to 10 `eth_transactionCount`
requests
2. then we scan chain for eth transfers using `eth_getBalance` and
`eth_transactionCount` (for double checking zero balances)
3. we make sure that we do not scan db for more than 30 blocks with
transfers. That's important for accounts with mostly incoming
transactions, because the range found on the first step might
contain any number of incoming transfers, but only 20-25 outgoing
transactions
4. when we found ~30 blocks in a given range, we update initial
range `from` block using the oldest found block
5. and now we scan db for erc20transfers using `eth_getLogs`
`oldest-found-eth-block`-`latest-block`, we make not more than 20 calls
6. when all blocks which contain incoming/outgoing transfers for a
given address are found, we save these blocks to db and mark that
transfers from these blocks are still to be fetched
7. Then we select latest ~30 (the number can be adjusted) blocks from
these which were found and fetch transfers, this requires 3-4
requests per transfer.
8. we persist scanned range so that we know were to start next time
9. we dispatch an event which tells client that transactions are found
10. client fetches latest 20 transfers
- when user presses "fetch more" button we check if app's db contains next
20 transfers, if not we scan chain again and return transfers after
small fixes
Move settings table schema from a key-value store to a one row table with many columns.
We now save the first row with initial data in saveAccountAndLogin and follow up saveSetting calls are only saving one setting at a time.
