* Add Metadata to messages, expose new messenger methods
This commits modifies deduplicator so that it takes a `StatusMessage`
instead of `WhisperMessage` and also returns a `Metadata` field which is
then passed back by the client when confirming messages, which fixes the
issue we had with not confirming pfs messages.
This commit moves envelopes tracking to status-go.
Post endpoint is not going to track envelopes anymore, as that's taken
care on status-protocol-go side, so this is a breaking change, and
version is updated accordingly.
Adds support for datasync, V1Messages and disabling the discovery topic.
This is a backward compatible change as long as they are not toggled on
(they are not by default).
* add multiaccount support
add multi account ImportPrivateKey and StoreAccount
test derivation from normal keys
* add multiaccount to mobile pkg
* use multiaccount params structs from the mobile pkg
* move multiaccount tests together with the other lib tests
* fix codeclimate warning and temporarily increase methods threshold
* split library_test_utils.go to avoid linter warnings
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.
As part of a performance profiling of mailserver we noticed that most of
the resources on a query are spend decoding the whisper envelope.
This PR changes the way we store envelopes encoding the Topic into the
database key, so we can check that and we are able to publish the
envelope rawValue if it matches.
The change is backward compatible as only newly added envelopes will
have the new key, while old ones will have to be unmarshaled.
* Notify users that envelope was discarded and retry sending it
* Update Gopkg files with released whisper version
* Forgot to remove signal after refactoring
Currently PFS messages are decrypted and therefore modified before being
passed to the client. This make IDs computation difficult, as we pass
the whole object to the client and expect the object be passed back once
confirmed.
This changes the behavior allowing confirmation by ID, which is passed
to the client instead of the raw object.
This is a breaking change, but status-react is already forward
compatible.
Libp2p keeps stream open if EOF wasn't seen and we called Close method.
The most important change is that reader now uses FullClose util, that will
wait for EOF character before closing the stream.
These changes add a support for syncing data between two Mail Servers. It does not give an easy way to start syncing. This will be solved in the next PR.
This change implements connection manager that monitors 3 types of events:
1. update of the selected mail servers
2. disconnect from a mail server
3. errors for requesting mail history
When selected mail servers provided we will try to connect with as many as possible, and later disconnect the surplus. For example if we want to connect with one mail server and 3 were selected, we try to connect with all (3), and later disconnect with 2. It will to establish connection with live mail server faster.
If mail server disconnects we will choose any other mail server from the list of selected. Unless we have only one mail server. In such case we don't have any other choice and we will leave things as is.
If request for history was expired we will disconnect such peer and try to find another one. We will follow same rules as described above.
We will have two components that will rely on this logic:
1. requesting history
If target peer is provided we will use that peer, otherwise we will request history from any selected mail server that is connected at the time of request.
2. confirmation from selected mail server
Confirmation from any selected mail server will bee used to send a feedback that envelope was sent.
I will add several extensions, but probably in separate PRs:
1. prioritize connection with mail server that was used before reboot
2. disconnect from mail servers if history request wasn't expired but failed.
3. wait some time in RequestsMessage RPC to establish connection with any mail server
Currently this feature is hidden, as certain changes will be necessary in status-react.

This commit updates geth to 1.8.17 and adds a possibility to enable metrics during compilation time.
The cascade of issues forced us to upgrade geth to 1.8.17 in order to allow enabling metrics during compilation time. 1.8.17 introduced `NodeID` refactoring and `enode` package which affected our peers pool and integration with Discovery V5.
- Skipped keys
The purpose of limiting the number of skipped keys generated is to avoid a dos
attack whereby an attacker would send a large N, forcing the device to
compute all the keys between currentN..N .
Previously the logic for handling skipped keys was:
- If in the current receiving chain there are more than maxSkip keys,
throw an error
This is problematic as in long-lived session dropped/unreceived messages starts
piling up, eventually reaching the threshold (1000 dropped/unreceived
messages).
This logic has been changed to be more inline with signals spec, and now
it is:
- If N is > currentN + maxSkip, throw an error
The purpose of limiting the number of skipped keys stored is to avoid a dos
attack whereby an attacker would force us to store a large number of
keys, filling up our storage.
Previously the logic for handling old keys was:
- Once you have maxKeep ratchet steps, delete any key from
currentRatchet - maxKeep.
This, in combination with the maxSkip implementation, capped the number of stored keys to
maxSkip * maxKeep.
The logic has been changed to:
- Keep a maximum of MaxMessageKeysPerSession
and additionally we delete any key that has a sequence number <
currentSeqNum - maxKeep
- Version
We check now the version of the bundle so that when we get a bundle from
the same installationID with a higher version, we mark the previous
bundle as expired and use the new bundle the next time a message is sent

Other changes:
* needed to patch that loop implementation in Discover V5 implementation in go-ethereum,
* fixed TestStatusNodeReconnectStaticPeers,
* fixed TestBackendAccountsConcurrently.
This change makes invalidation mechanism more aggressive. With a primary goal to invalidate short living nodes faster. In current setup any node that became known in terms of discovery will stay in this state until it will fail to respond to 5 queries. Removing them earlier from a table allows to reduce latency for finding required nodes.
The second change, one adds a version for discovery, separates status dht from ethereum dht.
After we rolled out discovery it became obvious that our boot nodes became spammed with irrelevant nodes. And this made discovery process very long, for example with separate dht discovery takes ~2s, with mutual dht - it can take 1m-10m and there is still no guarantee to find a max amount of peers, cause status nodes is a very small part of whole ethereum infra.
In my understanding, we don't need to be a part of ethereum dht, and lower latency is way more important for us.
Closes: #941
Partially closes: #960 (960 requires futher investigations on devices)
Now if Add is to be called it will be called before Wait, this is achieved
by doing following:
- if cancel() gets lock first and closes channelCh before spawnSync is called
we will exit right away
- if not than we will ensure that we hold a lock until syncers are spawned
so that cancel() will be blocked for this time and it will prevent whole Terminate() from
progressing
This change adds adds an ability to use different source of time for whisper:
when envelope is created it is used to set expiry
to track when envelope needs to be expired
This time is then used to check validity of the envelope when it is received. Currently If we receive an envelope that is sent from future - peer will get disconnected. If envelope that was received has an expiry less then now it will be simply dropped, if expiry is less than now + 10*2 seconds peer will get dropped.
So, it is clear that whisper depends on time. And any time we get a skew with peers that is > 20s reliability will be grealy reduced.
In this change another source of time for whisper will be used. This time source will use ntp servers from pool.ntp.org to compute offset. When whisper queries time - this offset will be added/substracted from current time.
Query is executed every 2 mins, queries 5 different servers, cut offs min and max and the computes mean value. pool.ntp.org is resolved to different servers and according to documentation you will rarely hit the same.
Closes: #687
* Rebase on 1.8.5
* Remove outdated patches and apply all others
* Use shh_post that returns hash
* Use bloom filter for request to mailserver
* Remove tests for sending messages without subbing first
* Fix deadlock in ethdb
* Expect null if receipt is not yet created
* Subscribe to messages before sending them in whisper test
* Add default peer limits configuration
If discovery is enabled for a given cluster - we will set a default
expected number of peers for each enabled service. For example:
- if cluster is rinkeby has a discovery enabled we will
check which services are enabled
- if whisper is enabled we will set min and max limits by default
- if les is enabled and infura is not used we will set limits too
When statusd is used - configuration must be provided using configuration
supported by statusd.
* Fix deadlock in les peer set
