Jakub Sokołowski cca47ef6e1 rename gomarkdown/markdown to status-im/markdown
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which was using a newer version of the same package.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.

Remove protocol and eth-node submodules (#1835) 2020-02-10 12:22:37 +01:00
Roman Volosovskyi dc80cb0e06
Cleanup after tx fetching changes
- 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.

Verify ENS in the background (#1824)
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.

[status-im/status-react#9927] Fast blocks sync after delay
- 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.

status-im/status-react#9203 Faster tx fetching with less request
*** 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

Handle membership update message
This commit does a few things:

1) Handle membership updates using protobuf and adds the relevant
endpoints.
2) Store in memory a map of chats + contacts for faster lookups, which
are then flushed to disk on each update
3) Validate incoming messages

Sorry for the large pr, but you know, v1 :)

Replace address with keyUid in accounts db
Account's address was used as a primary key in accounts db and as a
deterministic id of an account in some API calls. Also it was used as a
part of the name of the account specific database. This revealed some
extra information about the account and wasn't necessary.
At first the hash of the address was planned to be used as a
deterministic id, but we already have a keyUid which is calculated as
sha256 hash of account's public key and has similar properties:
- it is deterministic
- doesn't reveal accounts public key or address in plain

Move to protobuf for Message type (#1706)
* Use a single Message type `v1/message.go` and `message.go` are the same now, and they embed `protobuf.ChatMessage`

* Use `SendChatMessage` for sending chat messages, this is basically the old `Send` but a bit more flexible so we can send different message types (stickers,commands), and not just text.

* Remove dedup from services/shhext. Because now we process in status-protocol, dedup makes less sense, as those messages are going to be processed anyway, so removing for now, we can re-evaluate if bringing it to status-go or not.

* Change the various retrieveX method to a single one:
`RetrieveAll` will be processing those messages that it can process (Currently only `Message`), and return the rest in `RawMessages` (still transit). The format for the response is:
`Chats`: -> The chats updated by receiving the message
`Messages`: -> The messages retrieved (already matched to a chat)
`Contacts`: -> The contacts updated by the messages
`RawMessages` -> Anything else that can't be parsed, eventually as we move everything to status-protocol-go this will go away.

Andrea Maria Piana cef7f367ab Add topic negotiation
This commit add topic negotiation to the protocol.

On receiving a message from a client with version >= 1, we will generate
a shared key using Diffie-Hellman. We will record also which
installationID has sent us a message.

This key will be passed back to the above layer, which will then use to
start listening to a whisper topic (the `chat` namespace has no
knowledge of whisper).

When sending a message to a set of InstallationIDs, we check whether we
have agreed on a topic with all of them, and if so, we will send on this
separate topic, otherwise we fallback on discovery.

This change is backward compatible, as long as there is no downgrade of
the app on the other side.

A few changes:

* Factored out the DB in a separate namespace as now it is
being used by multiple services (TopicService and EncryptionService).

* Factored out multidevice management in a separate namespace

* Moved all the test to test the whole protoocl rather than just the encryption service

* Moved all the filter management in status-go

Fix channel subscriber that was blocking sending new requests (#1465)
In RequestMessagesSync subscriber is listening to a feed where all whisper
events are posted. After we received event with a request hash - subscriber will
stop actively consuming messages from a feed, as a subscription channel will
get overflow and whole feed will get blocked.

Some events are posted to a feed before request is sent, so blocked feed results
in blocked sending.

Now we will unsubscribe after relevant event was received, and terminate subscriber
explicitly by timeout.

Andrea Maria Piana 4ab08629f6 Add postgres
This commits adds support for postgres database.
Currently two fields are stored: the bloom filter and the topic.
Only the bloom filter is actually used to query, but potentially we will
use also the topic in the future, so easier to separate it now in order
to avoid a migration.
