* Upgrade geth to v1.9.14 (#75) * fix: resolve conflict * chg: use bor url for import * Fix regressions from merge Co-authored-by: Jaynti Kanani <jdkanani@gmail.com> * Bor update 1.9.16 (#77) * cmd, consensus: add option to disable mmap for DAG caches/datasets (#20484) * cmd, consensus: add option to disable mmap for DAG caches/datasets * consensus: add benchmarks for mmap with/with lock * cmd/clef: add newaccount command (#20782) * cmd/clef: add newaccount command * cmd/clef: document clef_New, update API versioning * Update cmd/clef/intapi_changelog.md Co-Authored-By: ligi <ligi@ligi.de> * Update signer/core/uiapi.go Co-Authored-By: ligi <ligi@ligi.de> Co-authored-by: ligi <ligi@ligi.de> * eth: add debug_accountRange API (#19645) This new API allows reading accounts and their content by address range. Co-authored-by: Martin Holst Swende <martin@swende.se> Co-authored-by: Felix Lange <fjl@twurst.com> * travis: allow cocoapods deploy to fail (#20833) * whisper/whisperv6: decrease pow requirement in tests (#20815) * metrics: improve TestTimerFunc (#20818) The test failed due to what appears to be fluctuations in time.Sleep, which is not the actual method under test. This change modifies it so we compare the metered Max to the actual time instead of the desired time. * les: create utilities as common package (#20509) * les: move execqueue into utilities package execqueue is a util for executing queued functions in a serial order which is used by both les server and les client. Move it to common package. * les: move randselect to utilities package weighted_random_selector is a helpful tool for randomly select items maintained in a set but based on the item weight. It's used anywhere is LES package, mainly by les client but will be used in les server with very high chance. So move it into a common package as the second step for les separation. * les: rename to utils * README: update private network genesis spec with istanbul (#20841) * add istanbul and muirGlacier to genesis states in README * remove muirGlacier, relocate istanbul * whisper: fix whisper go routine leak with sync wait group (#20844) * cmd/evm: Rework execution stats (#20792) - Dump stats also for --bench flag. - From memory stats only show number and size of allocations. This is what `test -bench` shows. I doubt others like number of GC runs are any useful, but can be added if requested. - Now the mem stats are for single execution in case of --bench. * cmd/devp2p, cmd/wnode, whisper: add missing calls to Timer.Stop (#20843) * p2p/server: add UDP port mapping goroutine to wait group (#20846) * accounts/abi faster unpacking of int256 (#20850) * p2p/discv5: add missing Timer.Stop calls (#20853) * miner/worker: add missing timer.Stop call (#20857) * cmd/geth: fix bad genesis test (#20860) * eth/filters: add missing Ticker.Stop call (#20862) * eth/fetcher: add missing timer.Stop calls (#20861) * les: add missing Ticker.Stop call (#20864) * event: add missing timer.Stop call in TestFeed (#20868) * metrics: add missing calls to Ticker.Stop in tests (#20866) * ethstats: add missing Ticker.Stop call (#20867) * p2p/discv5, p2p/testing: add missing Timer.Stop calls in tests (#20869) * core: add missing Timer.Stop call in TestLogReorgs (#20870) * rpc: add missing timer.Stop calls in websocket tests (#20863) * crypto/ecies: improve concatKDF (#20836) This removes a bunch of weird code around the counter overflow check in concatKDF and makes it actually work for different hash output sizes. The overflow check worked as follows: concatKDF applies the hash function N times, where N is roundup(kdLen, hashsize) / hashsize. N should not overflow 32 bits because that would lead to a repetition in the KDF output. A couple issues with the overflow check: - It used the hash.BlockSize, which is wrong because the block size is about the input of the hash function. Luckily, all standard hash functions have a block size that's greater than the output size, so concatKDF didn't crash, it just generated too much key material. - The check used big.Int to compare against 2^32-1. - The calculation could still overflow before reaching the check. The new code in concatKDF doesn't check for overflow. Instead, there is a new check on ECIESParams which ensures that params.KeyLen is < 512. This removes any possibility of overflow. There are a couple of miscellaneous improvements bundled in with this change: - The key buffer is pre-allocated instead of appending the hash output to an initially empty slice. - The code that uses concatKDF to derive keys is now shared between Encrypt and Decrypt. - There was a redundant invocation of IsOnCurve in Decrypt. This is now removed because elliptic.Unmarshal already checks whether the input is a valid curve point since Go 1.5. Co-authored-by: Felix Lange <fjl@twurst.com> * rpc: metrics for JSON-RPC method calls (#20847) This adds a couple of metrics for tracking the timing and frequency of method calls: - rpc/requests gauge counts all requests - rpc/success gauge counts requests which return err == nil - rpc/failure gauge counts requests which return err != nil - rpc/duration/all timer tracks timing of all requests - rpc/duration/<method>/<success/failure> tracks per-method timing * mobile: use bind.NewKeyedTransactor instead of duplicating (#20888) It's better to reuse the existing code to create a keyed transactor than to rewrite the logic again. * all: fix a bunch of inconsequential goroutine leaks (#20667) The leaks were mostly in unit tests, and could all be resolved by adding suitably-sized channel buffers or by restructuring the test to not send on a channel after an error has occurred. There is an unavoidable goroutine leak in Console.Interactive: when we receive a signal, the line reader cannot be unblocked and will get stuck. This leak is now documented and I've tried to make it slightly less bad by adding a one-element buffer to the output channels of the line-reading loop. Should the reader eventually awake from its blocked state (i.e. when stdin is closed), at least it won't get stuck trying to send to the interpreter loop which has quit long ago. Co-authored-by: Felix Lange <fjl@twurst.com> * internal/ethapi: add CallArgs.ToMessage method (#20854) ToMessage is used to convert between ethapi.CallArgs and types.Message. It reduces the length of the DoCall method by about half by abstracting out the conversion between the CallArgs and the Message. This should improve the code's maintainability and reusability. * eth, les: fix flaky tests (#20897) * les: fix flaky test * eth: fix flaky test * cmd/geth: enable metrics for geth import command (#20738) * cmd/geth: enable metrics for geth import command * cmd/geth: enable metrics-flags for import command * core/vm: use a callcontext struct (#20761) * core/vm: use a callcontext struct * core/vm: fix tests * core/vm/runtime: benchmark * core/vm: make intpool push inlineable, unexpose callcontext * docs/audits: add discv5 protocol audits from LA and C53 (#20898) * .github: change gitter reference to discord link in issue template (#20896) * couple of fixes to docs in clef (#20900) * p2p/discover: add initial discovery v5 implementation (#20750) This adds an implementation of the current discovery v5 spec. There is full integration with cmd/devp2p and enode.Iterator in this version. In theory we could enable the new protocol as a replacement of discovery v4 at any time. In practice, there will likely be a few more changes to the spec and implementation before this can happen. * build: upgrade to golangci-lint 1.24.0 (#20901) * accounts/scwallet: remove unnecessary uses of fmt.Sprintf * cmd/puppeth: remove unnecessary uses of fmt.Sprintf * p2p/discv5: remove unnecessary use of fmt.Sprintf * whisper/mailserver: remove unnecessary uses of fmt.Sprintf * core: goimports -w tx_pool_test.go * eth/downloader: goimports -w downloader_test.go * build: upgrade to golangci-lint 1.24.0 * whisper/mailserver : recover corrupt db files before opening (#20891) * whisper/mailserver : recover db file when openfile corrupted * whisper/mailserver : fix db -> s.db * whisper/mailserver : common/errors for dbfile * accounts/abi/bind: Refactored topics (#20851) * accounts/abi/bind: refactored topics * accounts/abi/bind: use store function to remove code duplication * accounts/abi/bind: removed unused type defs * accounts/abi/bind: error on tuples in topics * Cosmetic changes to restart travis build Co-authored-by: Guillaume Ballet <gballet@gmail.com> * node: allow websocket and HTTP on the same port (#20810) This change makes it possible to run geth with JSON-RPC over HTTP and WebSocket on the same TCP port. The default port for WebSocket is still 8546. geth --rpc --rpcport 8545 --ws --wsport 8545 This also removes a lot of deprecated API surface from package rpc. The rpc package is now purely about serving JSON-RPC and no longer provides a way to start an HTTP server. * crypto: improve error messages in LoadECDSA (#20718) This improves error messages when the file is too short or too long. Also rewrite the test for SaveECDSA because LoadECDSA has its own test now. Co-authored-by: Felix Lange <fjl@twurst.com> * changed date of rpcstack.go since new file (#20904) * accounts/abi/bind: fixed erroneous filtering of negative ints (#20865) * accounts/abi/bind: fixed erroneous packing of negative ints * accounts/abi/bind: added test cases for negative ints in topics * accounts/abi/bind: fixed genIntType for go 1.12 * accounts/abi: minor nitpick * cmd: deprecate --testnet, use named networks instead (#20852) * cmd/utils: make goerli the default testnet * cmd/geth: explicitly rename testnet to ropsten * core: explicitly rename testnet to ropsten * params: explicitly rename testnet to ropsten * cmd: explicitly rename testnet to ropsten * miner: explicitly rename testnet to ropsten * mobile: allow for returning the goerli spec * tests: explicitly rename testnet to ropsten * docs: update readme to reflect changes to the default testnet * mobile: allow for configuring goerli and rinkeby nodes * cmd/geth: revert --testnet back to ropsten and mark as legacy * cmd/util: mark --testnet flag as deprecated * docs: update readme to properly reflect the 3 testnets * cmd/utils: add an explicit deprecation warning on startup * cmd/utils: swap goerli and ropsten in usage * cmd/geth: swap goerli and ropsten in usage * cmd/geth: if running a known preset, log it for convenience * docs: improve readme on usage of ropsten's testnet datadir * cmd/utils: check if legacy `testnet` datadir exists for ropsten * cmd/geth: check for legacy testnet path in console command * cmd/geth: use switch statement for complex conditions in main * cmd/geth: move known preset log statement to the very top * cmd/utils: create new ropsten configurations in the ropsten datadir * cmd/utils: makedatadir should check for existing testnet dir * cmd/geth: add legacy testnet flag to the copy db command * cmd/geth: add legacy testnet flag to the inspect command * les, les/lespay/client: add service value statistics and API (#20837) This PR adds service value measurement statistics to the light client. It also adds a private API that makes these statistics accessible. A follow-up PR will add the new server pool which uses these statistics to select servers with good performance.

LocalNode returns the local node object.

The latter is allowed since evm itself is a blackbox and internal error is allowed to happen. This PR emphasizes the difference by introducing a executionResult structure.

p2p: new dial scheduler (#20592)
* p2p: new dial scheduler This change replaces the peer-to-peer dial scheduler with a new and improved implementation. The new code is better than the previous implementation in two key aspects: - The time between discovery of a node and dialing that node is significantly lower in the new version. The old dialState kept a buffer of nodes and launched a task to refill it whenever the buffer became empty. This worked well with the discovery interface we used to have, but doesn't really work with the new iterator-based discovery API. - Selection of static dial candidates (created by Server.AddPeer or through static-nodes.json) performs much better for large amounts of static peers. Connections to static nodes are now limited like dynanic dials and can no longer overstep MaxPeers or the dial ratio. * p2p/simulations/adapters: adapt to new NodeDialer interface * p2p: re-add check for self in checkDial * p2p: remove peersetCh * p2p: allow static dials when discovery is disabled * p2p: add test for dialScheduler.removeStatic * p2p: remove blank line * p2p: fix documentation of maxDialPeers * p2p: change "ok" to "added" in static node log * p2p: improve dialTask docs Also increase log level for "Can't resolve node" * p2p: ensure dial resolver is truly nil without discovery * p2p: add "looking for peers" log message * p2p: clean up Server.run comments * p2p: fix maxDialedConns for maxpeers < dialRatio Always allocate at least one dial slot unless dialing is disabled using NoDial or MaxPeers == 0. Most importantly, this fixes MaxPeers == 1 to dedicate the sole slot to dialing instead of listening. * p2p: fix RemovePeer to disconnect the peer again Also make RemovePeer synchronous and add a test. * p2p: remove "Connection set up" log message * p2p: clean up connection logging We previously logged outgoing connection failures up to three times. - in SetupConn() as "Setting up connection failed addr=..." - in setupConn() with an error-specific message and "id=... addr=..." - in dial() as "Dial error task=..." This commit ensures a single log message is emitted per failure and adds "id=... addr=... conn=..." everywhere (id= omitted when the ID isn't known yet). Also avoid printing a log message when a static dial fails but can't be resolved because discv4 is disabled. The light client hit this case all the time, increasing the message count to four lines per failed connection. * p2p: document that RemovePeer blocks |

p2p: enforce connection retry limit on server side (#19684)
The dialer limits itself to one attempt every 30s. Apply the same limit in Server and reject peers which try to connect too eagerly. The check against the limit happens right after accepting the connection. Further changes in this commit ensure we pass the Server logger down to Peer instances, discovery and dialState. Unit test logging now works in all Server tests. |

p2p, p2p/discover: add signed ENR generation (#17753)
This PR adds enode.LocalNode and integrates it into the p2p subsystem. This new object is the keeper of the local node record. For now, a new version of the record is produced every time the client restarts. We'll make it smarter to avoid that in the future. There are a couple of other changes in this commit: discovery now waits for all of its goroutines at shutdown and the p2p server now closes the node database after discovery has shut down. This fixes a leveldb crash in tests. p2p server startup is faster because it doesn't need to wait for the external IP query anymore. |

all: new p2p node representation (#17643)
Package p2p/enode provides a generalized representation of p2p nodes
which can contain arbitrary information in key/value pairs. It is also
the new home for the node database. The "v4" identity scheme is also
moved here from p2p/enr to remove the dependency on Ethereum crypto from
that package.
Record signature handling is changed significantly. The identity scheme
registry is removed and acceptable schemes must be passed to any method
that needs identity. This means records must now be validated explicitly
after decoding.
The enode API is designed to make signature handling easy and safe: most
APIs around the codebase work with enode.Node, which is a wrapper around
a valid record. Going from enr.Record to enode.Node requires a valid
signature.
* p2p/discover: port to p2p/enode
This ports the discovery code to the new node representation in
p2p/enode. The wire protocol is unchanged, this can be considered a
refactoring change. The Kademlia table can now deal with nodes using an
arbitrary identity scheme. This requires a few incompatible API changes:
- Table.Lookup is not available anymore. It used to take a public key
as argument because v4 protocol requires one. Its replacement is
LookupRandom.
- Table.Resolve takes *enode.Node instead of NodeID. This is also for
v4 protocol compatibility because nodes cannot be looked up by ID
alone.
- Types Node and NodeID are gone. Further commits in the series will be
fixes all over the the codebase to deal with those removals.
* p2p: port to p2p/enode and discovery changes
This adapts package p2p to the changes in p2p/discover. All uses of
discover.Node and discover.NodeID are replaced by their equivalents from
p2p/enode.
New API is added to retrieve the enode.Node instance of a peer. The
behavior of Server.Self with discovery disabled is improved. It now
tries much harder to report a working IP address, falling back to
127.0.0.1 if no suitable address can be determined through other means.
These changes were needed for tests of other packages later in the
series.
* p2p/simulations, p2p/testing: port to p2p/enode
No surprises here, mostly replacements of discover.Node, discover.NodeID
with their new equivalents. The 'interesting' API changes are:
- testing.ProtocolSession tracks complete nodes, not just their IDs.
- adapters.NodeConfig has a new method to create a complete node.
These changes were needed to make swarm tests work.
Note that the NodeID change makes the code incompatible with old
simulation snapshots.
* whisper/whisperv5, whisper/whisperv6: port to p2p/enode
This port was easy because whisper uses []byte for node IDs and
URL strings in the API.
* eth: port to p2p/enode
Again, easy to port because eth uses strings for node IDs and doesn't
care about node information in any way.
* les: port to p2p/enode
Apart from replacing discover.NodeID with enode.ID, most changes are in
the server pool code. It now deals with complete nodes instead
of (Pubkey, IP, Port) triples. The database format is unchanged for now,
but we should probably change it to use the node database later.
* node: port to p2p/enode
This change simply replaces discover.Node and discover.NodeID with their
new equivalents.
* swarm/network: port to p2p/enode
Swarm has its own node address representation, BzzAddr, containing both
an overlay address (the hash of a secp256k1 public key) and an underlay
address (enode:// URL).
There are no changes to the BzzAddr format in this commit, but certain
operations such as creating a BzzAddr from a node ID are now impossible
because node IDs aren't public keys anymore.
Most swarm-related changes in the series remove uses of
NewAddrFromNodeID, replacing it with NewAddr which takes a complete node
as argument. ToOverlayAddr is removed because we can just use the node
ID directly.

p2p: when peer is removed remove it also from dial history (#16060)
This change removes a peer information from dialing history when peer is removed from static list. It allows to force a server to re-dial concrete peer if it is needed. In our case we are running geth node on mobile devices, and it is common for a network connection to flap on mobile. Almost every time it flaps or network connection is changed from cellular to wifi peers are disconnected with read timeout. And usually it takes 30 seconds (default expiration timeout) to recover connection with static peers after connectivity is restored. This change allows us to reconnect with peers almost immediately and it seems harmless enough. |

p2p: new dialer, peer management without locks
The most visible change is event-based dialing, which should be an improvement over the timer-based system that we have at the moment. The dialer gets a chance to compute new tasks whenever peers change or dials complete. This is better than checking peers on a timer because dials happen faster. The dialer can now make more precise decisions about whom to dial based on the peer set and we can test those decisions without actually opening any sockets. Peer management is easier to test because the tests can inject connections at checkpoints (after enc handshake, after protocol handshake). Most of the handshake stuff is now part of the RLPx code. It could be exported or move to its own package because it is no longer entangled with Server logic. |
