e30b125725 consensus: double-sign risk reduction (ADR-51) (#5147)
Implementation spec of Double Signing Risk Reduction [ADR-51](https://github.com/tendermint/tendermint/blob/master/docs/architecture/adr-051-double-signing-risk-reduction.md) by B-Harvest
- Add `DoubleSignCheckHeight` config variable to ConsensusConfig for "How many blocks looks back to check existence of the node's consensus votes when before joining consensus"
- Add `consensus.double_sign_check_height` to `config.toml` and `tendermint node` as flag for set `DoubleSignCheckHeight`
- Set default `consensus.double_sign_check_height` to `0`  ( it could be adjustable in this PR, disable when 0  )

cc247c091b genesis: add support for arbitrary initial height (#5191)
Adds a genesis parameter `initial_height` which specifies the initial block height, as well as ABCI `RequestInitChain.InitialHeight` to pass it to the ABCI application, and `State.InitialHeight` to keep track of the initial height throughout the code. Fixes #2543, based on [RFC-002](https://github.com/tendermint/spec/pull/119). Spec changes in https://github.com/tendermint/spec/pull/135.

431618cef6 lite2: remove auto update (#4535)
We first introduced auto-update as a separate struct AutoClient, which
was wrapping Client and calling Update periodically.

// AutoClient can auto update itself by fetching headers every N seconds.
type AutoClient struct {
    base         *Client
    updatePeriod time.Duration
    quit         chan struct{}

    trustedHeaders chan *types.SignedHeader
    errs           chan error
}

// NewAutoClient creates a new client and starts a polling goroutine.
func NewAutoClient(base *Client, updatePeriod time.Duration) *AutoClient {
    c := &AutoClient{
        base:           base,
        updatePeriod:   updatePeriod,
        quit:           make(chan struct{}),
        trustedHeaders: make(chan *types.SignedHeader),
        errs:           make(chan error),
    }
    go c.autoUpdate()
    return c
}

// TrustedHeaders returns a channel onto which new trusted headers are posted.
func (c *AutoClient) TrustedHeaders() <-chan *types.SignedHeader {
    return c.trustedHeaders
}

// Err returns a channel onto which errors are posted.
func (c *AutoClient) Errs() <-chan error {
    return c.errs
}

// Stop stops the client.
func (c *AutoClient) Stop() {
    close(c.quit)
}

func (c *AutoClient) autoUpdate() {
    ticker := time.NewTicker(c.updatePeriod)
    defer ticker.Stop()

    for {
        select {
        case <-ticker.C:
            lastTrustedHeight, err := c.base.LastTrustedHeight()
            if err != nil {
                c.errs <- err
                continue
            }

            if lastTrustedHeight == -1 {
                // no headers yet => wait
                continue
            }

            newTrustedHeader, err := c.base.Update(time.Now())
            if err != nil {
                c.errs <- err
                continue
            }

            if newTrustedHeader != nil {
                 c.trustedHeaders <- newTrustedHeader
            }
        case <-c.quit:
            return
        }
    }
}

Later we merged it into the Client itself with the assumption that most clients will want it.

But now I am not sure. Neither IBC nor cosmos/relayer are using it. It increases complexity (Start/Stop methods).

That said, I think it makes sense to remove it until we see a need for it (until we better understand usage behavior). We can always introduce it later 😅. Maybe in the form of AutoClient.

f95409e070 lite2: move AutoClient into Client (#4326)
* lite2: move AutoClient into Client

Most of the users will want auto update feature, so it makes sense to
move it into the Client itself, rather than having a separate
abstraction (it makes the code cleaner, but introduces an extra thing
the user will need to learn).

Also, add `FirstTrustedHeight` func to Client to get first trusted height.

* fix db store tests

* separate examples for auto and manual clients

* AutoUpdate tries to update to latest state

NOT 1 header at a time

* fix errors

* lite2: make Logger an option

4bfec797e8 cli: debug sub-command (#4227)
## Issue

Implement a new subcommand: tendermint debug. This subcommand itself has two subcommands:

    $ tendermint debug kill <pid> </path/to/out.zip> --home=</path/to/app.d>

Writes debug info into a compressed archive. The archive will contain the following:

├── config.toml
├── consensus_state.json
├── net_info.json
├── stacktrace.out
├── status.json
└── wal

The Tendermint process will be killed.

    $ tendermint debug dump </path/to/out> --home=</path/to/app.d>

This command will perform similar to kill except it only polls the node and dumps debugging data every frequency seconds to a compressed archive under a given destination directory. Each archive will contain:

├── consensus_state.json
├── goroutine.out
├── heap.out
├── net_info.json
├── status.json
└── wal

Note:

    goroutine.out and heap.out will only be written if a profile address is provided and is operational.
    This command is blocking and will log any error.

replaces: #3327
closes: #3249

## Commits:

* Implement debug tool command stubs

* Implement net getters and zip logic

* Update zip dir API and add home flag

* Add simple godocs for kill aux functions

* Move IO util to new file and implement copy WAL func

* Implement copy config function

f7f034a8be privval: refactor Remote signers (#3370)
This PR is related to #3107 and a continuation of #3351

It is important to emphasise that in the privval original design, client/server and listening/dialing roles are inverted and do not follow a conventional interaction.

Given two hosts A and B:

    Host A is listener/client
    Host B is dialer/server (contains the secret key)
    When A requires a signature, it needs to wait for B to dial in before it can issue a request.
    A only accepts a single connection and any failure leads to dropping the connection and waiting for B to reconnect.

The original rationale behind this design was based on security.

    Host B only allows outbound connections to a list of whitelisted hosts.
    It is not possible to reach B unless B dials in. There are no listening/open ports in B.

This PR results in the following changes:

    Refactors ping/heartbeat to avoid previously existing race conditions.
    Separates transport (dialer/listener) from signing (client/server) concerns to simplify workflow.
    Unifies and abstracts away the differences between unix and tcp sockets.
    A single signer endpoint implementation unifies connection handling code (read/write/close/connection obj)
    The signer request handler (server side) is customizable to increase testability.
    Updates and extends unit tests

A high level overview of the classes is as follows:

Transport (endpoints): The following classes take care of establishing a connection

    SignerDialerEndpoint
    SignerListeningEndpoint
    SignerEndpoint groups common functionality (read/write/timeouts/etc.)

Signing (client/server): The following classes take care of exchanging request/responses

    SignerClient
    SignerServer

This PR also closes #3601
