We must check if the channel is still open. The alternative approach is to not close any channels, which seems a bit odd. Fixes #2408 * docs: add client#Start/Stop to examples in RPC docs (#2939) follow-up on https://github.com/tendermint/tendermint/pull/2936 * Minor log changes (#2959) * node: allow state and code to have diff block versions * node: pex is a log module * p2p: panic on transport error (#2968) * p2p: panic on transport error Addresses #2823. Currently, the acceptRoutine exits if the transport returns an error trying to accept a new connection. Once this happens, the node can't accept any new connections. So here, we panic instead. While we could potentially be more intelligent by rerunning the acceptRoutine, the error may indicate something more fundamental (eg. file desriptor limit) that requires a restart anyways. We can leave it to process managers to handle that restart, and notify operators about the panic. * changelog * p2p: fix peer count mismatch #2332 (#2969) * p2p: test case for peer count mismatch #2332 * p2p: fix peer count mismatch #2332 * changelog * use httptest.Server to scrape Prometheus metrics * kv indexer: add separator to start key when matching ranges (#2925) * kv indexer: add separator to start key when matching ranges to avoid including false positives Refs #2908 * refactor code * add a test case * update changelog and upgrading (#2974) * don't ignore key when executing CONTAINS (#2924) Fixes #2912 * return an error if validator set is empty in genesis file and after InitChain (#2971) Fixes #2951 * docs: relative links in docs/spec/readme.md, js-amino lib (#2977) Co-Authored-By: zramsay * turn off strict routability every time (#2983) previously, we're turning it off only when --populate-persistent-peers flag was used, which is obviously incorrect. Fixes https://github.com/cosmos/cosmos-sdk/issues/2983 * Make mempool fail txs with negative gas wanted (#2994) This is only one part of #2989. We also need to fix the application, and add rules to consensus to ensure this. * p2p: set MConnection#created during init (#2990) Fixes #2715 In crawlPeersRoutine, which is performed when seedMode is run, there is logic that disconnects the peer's state information at 3-hour intervals through the duration value. The duration value is calculated by referring to the created value of MConnection. When MConnection is created for the first time, the created value is not initiated, so it is not disconnected every 3 hours but every time it is disconnected. So, normal nodes are connected to seedNode and disconnected immediately, so address exchange does not work properly. https://github.com/tendermint/tendermint/blob/master/p2p/pex/pex_reactor.go#L629 This point is not work correctly. I think, https://github.com/tendermint/tendermint/blob/master/p2p/conn/connection.go#L148 created variable is missing the current time setting. * Make testing logger that doesn't write to stdout (#2997) * add UnconfirmedTxs/NumUnconfirmedTxs methods to HTTP/Local clients (#2964) * docs: fixes from 'first time' review (#2999) * docs: enable full-text search (#3004) * mempool: add a comment and missing changelog entry (#2996) Refs #2994 * circleci: add a job to automatically update docs (#3005) * docs: add edit on Github links (#3014) * docs: update DOCS_README (#3019) Co-Authored-By: zramsay * mempool: notifyTxsAvailable if there're txs left, but recheck=false (#2991) (left after committing a block) Fixes #2961 -------------- ORIGINAL ISSUE Tendermint version : 0.26.4-b771798d ABCI app : kv-store Environment: OS (e.g. from /etc/os-release): macOS 10.14.1 What happened: Set mempool.recheck = false and create empty block = false in config.toml. When transactions get added right between a new empty block is being proposed and committed, the proposer won't propose new block for that transactions immediately after. That transactions are stuck in the mempool until a new transaction is added and trigger the proposer. What you expected to happen: If there is a transaction left in the mempool, new block should be proposed immediately. Have you tried the latest version: yes How to reproduce it (as minimally and precisely as possible): Fire two transaction using broadcast_tx_sync with specific delay between them. (You may need to do it multiple time before the right delay is found, on my machine the delay is 0.98s) Logs (paste a small part showing an error (< 10 lines) or link a pastebin, gist, etc. containing more of the log file): https://pastebin.com/0Wt6uhPF Config (you can paste only the changes you've made): [mempool] recheck = false create_empty_block = false Anything else we need to know: In mempool.go, we found that proposer will immediately propose new block if Last committed block has some transaction (causing AppHash to changed) or mem.notifyTxsAvailable() is called. Our scenario is as followed. A transaction is fired, it will create 1 block with 1 tx (line 1-4 in the log) and 1 empty block. After the empty block is proposed but before it is committed, second transaction is fired and added to mempool. (line 8-16) Now, since the last committed block is empty and mem.notifyTxsAvailable() will be called only if mempool.recheck = true. The proposer won't immediately propose new block, causing the second transaction to stuck in mempool until another transaction is added to mempool and trigger mem.notifyTxsAvailable(). * During replay, when appHeight==0, only saveState if stateHeight is also 0 (#3006) * optimize addProposalBlockPart * optimize addProposalBlockPart * if ProposalBlockParts and LockedBlockParts both exist,let LockedBlockParts overwrite ProposalBlockParts. * fix tryAddBlock * broadcast lockedBlockParts in higher priority * when appHeight==0, it's better fetch genDoc than state.validators. * not save state if replay from height 1 * only save state if replay from height 1 when stateHeight is also 1 * only save state if replay from height 1 when stateHeight is also 1 * only save state if replay from height 0 when stateHeight is also 0 * handshake info's response version only update when stateHeight==0 * save the handshake responseInfo appVersion * 2980 fix cors (#3021) * config: cors options are arrays of strings, not strings Fixes #2980 * docs: update tendermint-core/configuration.html page * set allow_duplicate_ip to false * in `tendermint testnet`, set allow_duplicate_ip to true Refs #2712 * fixes after Ismail's review * Revert "set allow_duplicate_ip to false" This reverts commit 24c1094ebcf2bd35f2642a44d7a1e5fb5c178fb1. * #2980 fix cors doc (#3013) * docs: networks/docker-compose: small fixes (#3017) * Bucky/v0.27.1 (#3022) * update changelog * linkify * changelog and version * Revert to using defers in addrbook.

Committing this to collaborate on the error. * Removes extraneous logging * Completes testing of Unix sockets client version This completes the testing of the client connecting via Unix sockets. There are two specific tests (TestSocketPVDeadline and TestRemoteSignerRetryTCPOnly) that are only relevant to TCP connections. * Renames test to show TCP-specificity * Adds testing into closures for consistency (forgot previously) * Moves test specific to RemoteSigner into own file As per discussion on #3132, `TestRemoteSignerRetryTCPOnly` doesn't really belong with the client tests.

Timeout deadlines are now tested for both TCP and Unix domain socket connections. There is also no need for the additional secret connection code: the connection will time out at the `acceptConnection()` phase for TCP connections, and will time out when attempting to obtain the `RemoteSigner`'s public key for Unix domain socket connections. * Removes extraneous logging * Adds IsConnTimeout helper function This commit adds a helper function to detect whether an error is either a fundamental networking timeout error, or an `ErrConnTimeout` error specific to the `RemoteSigner` class. * Adds a test for the IsConnTimeout() helper function * Separates tests logically for IsConnTimeout * docs: fix RPC links (#3141) * Bucky/fix evidence halt (#34) * consensus: createProposalBlock function * blockExecutor.CreateProposalBlock -

Here we decrease the retry timeout so we can try many times before the accept timeout. * p2p: increase handshake timeout in test This fails sometimes, presumably because the handshake timeout is so low (only 50ms). So increase it to 1s. Should fix #3187 * privval: fix race with ping. closes #3237 Pings happen in a go-routine and can happen concurrently with other messages. Since we use a request/response protocol, we expect to send a request and get back the corresponding response. But with pings happening concurrently, this assumption could be violated. We were using a mutex, but only a RWMutex, where the RLock was being held for sending messages - this was to allow the underlying connection to be replaced if it fails. Turns out we actually need to use a full lock (not just a read lock) to prevent multiple requests from happening concurrently. * node: fix test name. DelayedStop -> DelayedStart * autofile: Wait() method In the TestWALTruncate in consensus/wal_test.go we remove the WAL directory at the end of the test. However the wal.Stop() does not properly wait for the autofile group to finish shutting down. Hence it was possible that the group's go-routine is still running when the cleanup happens, which causes a panic since the directory disappeared. Here we add a Wait() method to properly wait until the go-routine exits so we can safely clean up. This fixes #2852. * p2p/conn: don't hold stopMtx while waiting (#3254) * p2p/conn: fix deadlock in FlushStop/OnStop * makefile: set_with_deadlock * close doneSendRoutine at end of sendRoutine * conn: initialize channs in OnStart * Add remote signer test harness (KMS) (#3149) * WIP: Starts adding remote signer test harness This commit adds a new command to Tendermint to allow for us to build a standalone binary to test remote signers such as KMS (https://github.com/tendermint/kms). Right now, all it does is test that the local public key matches the public key reported by the client, and fails at the point where it attempts to get the client to sign a proposal. * Fixes typo * Fixes proposal validation test This commit fixes the proposal validation test as per #3149. It also moves the test harness into its own internal package to isolate its exports from the `privval` package. * Adds vote signing validation * Applying recommendations from #3149 * Adds function descriptions for test harness * Adds ability to ask remote signer to shut down Prior to this commit, the remote signer needs to manually be shut down, which is not ideal for automated testing. This commit allows us to send a poison pill message to the KMS to let it shut down gracefully once testing is done (whether the tests pass or fail). * Adds tests for remote signer test harness This commit makes some minor modifications to a few files to allow for testing of the remote signer test harness. Two tests are added here: checking for a fully successful (the ideal) case, and for the case where the maximum number of retries has been reached when attempting to accept incoming connections from the remote signer. * Condenses serialization of proposals and votes using existing Tendermint functions * Removes now-unnecessary amino import and codec * Adds error message for vote signing failure * Adds key extraction command for integration test Took the code from here: https://gist.github.com/Liamsi/a80993f24bff574bbfdbbfa9efa84bc7 to create a simple utility command to extract a key from a local Tendermint validator for use in KMS integration testing. * Makes path expansion success non-compulsory * Fixes segfault on SIGTERM We need an additional variable to keep track of whether we're successfully connected, otherwise hitting Ctrl+Break during execution causes a segmentation fault. This now allows for a clean shutdown. * Consolidates shutdown checks * Adds comments indicating codes for easy lookup * Adds Docker build for remote signer harness Updates the `DOCKER/build.sh` and `DOCKER/push.sh` files to allow one to override the image name and Dockerfile using environment variables. Updates the primary `Makefile` as well as the `DOCKER/Makefile` to allow for building the `remote_val_harness` Docker image. * Adds build_remote_val_harness_docker_image to .PHONY * Removes remote signer poison pill messaging functionality * Reduces fluff code in command line parsing As per https://github.com/tendermint/tendermint/pull/3149#pullrequestreview-196171788, this reduces the amount of fluff code in the PR down to the bare minimum. * Fixes ordering of error check and info log * Moves remove_val_harness cmd into tools folder It seems to make sense to rather keep the remote signer test harness in its own tool folder (now rather named `tm-signer-harness` to keep with the tool naming convention). It is actually a separate tool, not meant to be one of the core binaries, but supplementary and supportive. * Updates documentation for tm-signer-harness * Refactors flag parsing to be more compact and less redundant * Adds version sub-command help * Removes extraneous flags parsing * Adds CHANGELOG_PENDING entry for tm-signer-harness * Improves test coverage Adds a few extra parameters to the `MockPV` type to fake broken vote and proposal signing. Also adds some more tests for the test harness so as to increase coverage for failed cases. * Fixes formatting for CHANGELOG_PENDING.md * Fix formatting for documentation config * Point users towards official Tendermint docs for tools documentation * Point users towards official Tendermint docs for tm-signer-harness * Remove extraneous constant * Rename TestHarness.sc to TestHarness.spv for naming consistency * Refactor to remove redundant goroutine * Refactor conditional to cleaner switch statement and better error handling for listener protocol * Remove extraneous goroutine * Add note about installing tmkms via Cargo * Fix typo in naming of output signing key * Add note about where to find chain ID * Replace /home/user with ~/ for brevity * Fixes "signer.key" typo * Minor edits for clarification for tm-signer-harness bulid/setup process * p2p: fix infinite loop in addrbook (#3232) * failing test * fix infinite loop in addrbook There are cases where we only have a small number of addresses marked good ("old"), but the selection mechanism keeps trying to select more of these addresses, and hence ends up in an infinite loop. Here we fix this to only try and select such "old" addresses if we have enough of them. Note this means, if we don't have enough of them, we may return more "new" addresses than otherwise expected by the newSelectionBias. This whole GetSelectionWithBias method probably needs to be rewritten, but this is a quick fix for the issue. * changelog * fix infinite loop if not enough new addrs * fix another potential infinite loop if a.nNew == 0 -> pickFromOldBucket=true, but we don't have enough items (a.nOld > len(oldBucketToAddrsMap) false) * Revert "fix another potential infinite loop" This reverts commit 146540c1125597162bd89820d611f6531f5e5e4b. * check num addresses instead of buckets, new test * fixed the int division * add slack to bias % in test, lint fixes * Added checks for selection content in test * test cleanup * Apply suggestions from code review Co-Authored-By: ebuchman * address review comments * change after Anton's review comments * use the same docker image we use for testing when building a binary for localnet * switch back to circleci classic * more review comments * more review comments * refactor addrbook_test * build linux binary inside docker in attempt to fix ``` --> Running dep + make build-linux GOOS=linux GOARCH=amd64 make build make[1]: Entering directory `/home/circleci/.go_workspace/src/github.com/tendermint/tendermint' CGO_ENABLED=0 go build -ldflags "-X github.com/tendermint/tendermint/version.GitCommit=`git rev-parse --short=8 HEAD`" -tags 'tendermint' -o build/tendermint ./cmd/tendermint/ p2p/pex/addrbook.go:373:13: undefined: math.Round ``` * change dir from /usr to /go * use concrete Go version for localnet binary * check for nil addresses just to be sure * addrbook_test: preallocate memory for bookSizes (#3268) Fixes https://circleci.com/gh/tendermint/tendermint/44901 * prepare v0.29.2 (#3272) * update changelog * linkify * bump version * update main changelog * final fixes * entry for wal fix * changelog preamble * remove a line * secp256k1: change build tags (#3277) * remove MixEntropy (#3278) * remove MixEntropy * changelog * review comment: cleaner constant for N/2, delete secp256k1N and use (#3279) `secp256k1.S256().N` directly instead * treat validator updates as set (#3222) * Initial commit for 3181..still early * unit test updates * unit test updates * fix check of dups accross updates and deletes * simplify the processChange() func * added overflow check utest * Added checks for empty valset, new utest * deepcopy changes in processUpdate() * moved to new API, fixed tests * test cleanup * address review comments * make sure votePower > 0 * gofmt fixes * handle duplicates and invalid values * more work on tests, review comments * Renamed and explained K * make TestVal private * split verifyUpdatesAndComputeNewPriorities.., added check for deletes * return error if validator set is empty after processing changes * address review comments * lint err * Fixed the total voting power and added comments * fix lint * fix lint * Sec/bucky/35 commit duplicate evidence (#36) Don't add committed evidence to evpool * Reject blocks with committed evidence (#37) * evidence: NewEvidencePool takes evidenceDB * evidence: failing TestStoreCommitDuplicate tendermint/security#35 * GetEvidence -> GetEvidenceInfo * fix TestStoreCommitDuplicate * comment in VerifyEvidence * add check if evidence was already seen -

improve ResetTestRootWithChainID() concurrency safety Rely on ioutil.TempDir() to create test root directories and ensure multiple same-chain id test cases can run in parallel. * Update config/toml.go Co-Authored-By: alessio * clean up test directories after completion Closes: #1034 * Remove redundant EnsureDir call * s/PanicSafety()/panic()/s * Put create dir functionality back in ResetTestRootWithChainID * Place test directories in OS's tempdir In modern UNIX and UNIX-like systems /tmp is very often mounted as tmpfs. This might speed test execution a bit. * Set 0700 to a const * rootsDirs -> configRootDirs * Don't double remove directories * Avoid global variables * Fix consensus tests * Reduce defer stack * Address review comments * Try to fix tests * Update CHANGELOG_PENDING.md Co-Authored-By: alessio * Update consensus/common_test.go Co-Authored-By: alessio * Update consensus/common_test.go Co-Authored-By: alessio * 3291 follow-up (#3323) * changelog: use issue number instead of PR number * follow up to #3291 - rpc/test/helpers.go add StopTendermint(node) func - remove ensureDir(filepath.Dir(walFile), 0700) - mempool/mempool_test.go add type cleanupFunc func() * cmd/show_validator: wrap err to make it more clear * p2p: check secret conn id matches dialed id (#3321) ref: [#3010 (comment)](https://github.com/tendermint/tendermint/issues/3010#issuecomment-464287627) > I tried searching for code where we authenticate a peer against its NetAddress.ID and couldn't find it. I don't see a reason to switch to Noise, but a need to ensure that the node's ID is authenticated e.g. after dialing from the address book. * p2p: check secret conn id matches dialed id * Fix all p2p tests & make code compile * add simple test for dialing with wrong ID * update changelog * address review comments * yet another place where to use IDAddressString and fix testSetupMultiplexTransport * update changelog and bump version * cs: sync WAL more frequently (#3300) As per #3043, this adds a ticker to sync the WAL every 2s while the WAL is running. * Flush WAL every 2s This adds a ticker that flushes the WAL every 2s while the WAL is running. This is related to #3043. * Fix spelling * Increase timeout to 2mins for slower build environments * Make WAL sync interval configurable * Add TODO to replace testChan with more comprehensive testBus * Remove extraneous debug statement * Remove testChan in favour of using system time As per https://github.com/tendermint/tendermint/pull/3300#discussion_r255886586, this removes the `testChan` WAL member and replaces the approach with a system time-oriented one. In this new approach, we keep track of the system time at which each flush and periodic flush successfully occurred. The naming of the various functions is also updated here to be more consistent with "flushing" as opposed to "sync'ing". * Update naming convention and ensure lock for timestamp update * Add Flush method as part of WAL interface Adds a `Flush` method as part of the WAL interface to enforce the idea that we can manually trigger a WAL flush from outside of the WAL. This is employed in the consensus state management to flush the WAL prior to signing votes/proposals, as per https://github.com/tendermint/tendermint/issues/3043#issuecomment-453853630 * Update CHANGELOG_PENDING * Remove mutex approach and replace with DI The dependency injection approach to dealing with testing concerns could allow similar effects to some kind of "testing bus"-based approach. This commit introduces an example of this, where instead of relying on (potentially fragile) timing of things between the code and the test, we inject code into the function under test that can signal the test through a channel. This allows us to avoid the `time.Sleep()`-based approach previously employed. * Update comment on WAL flushing during vote signing Co-Authored-By: thanethomson * Simplify flush interval definition Co-Authored-By: thanethomson * Expand commentary on WAL disk flushing Co-Authored-By: thanethomson * Add broken test to illustrate WAL sync test problem Removes test-related state (dependency injection code) from the WAL data structure and adds test code to illustrate the problem with using `WALGenerateNBlocks` and `wal.SearchForEndHeight` to test periodic sync'ing. * Fix test error messages * Use WAL group buffer size to check for flush A function is added to `libs/autofile/group.go#Group` in order to return the size of the buffered data (i.e. data that has not yet been flushed to disk). The test now checks that, prior to a `time.Sleep`, the group buffer has data in it. After the `time.Sleep` (during which time the periodic flush should have been called), the buffer should be empty. * Remove config root dir removal from #3291 * Add godoc for NewWAL mentioning periodic sync * docs: fix rpc Tx() method docs (#3331) * update changelog * cs: update wal comments (#3334) * cs: update wal comments Follow-up to https://github.com/tendermint/tendermint/pull/3300 * Update consensus/wal.go Co-Authored-By: melekes * refactor decideProposal in common_test (#3343) * fix TestWALPeriodicSync (#3342) The test was sometimes failing due to processFlushTicks being called too early. The solution is to call wal#Start later in the test. * pubsub 2.0 (#3227) * green pubsub tests :OK: * get rid of clientToQueryMap * Subscribe and SubscribeUnbuffered * start adapting other pkgs to new pubsub * nope * rename MsgAndTags to Message * remove TagMap it does not bring any additional benefits * bring back EventSubscriber * fix test * fix data race in TestStartNextHeightCorrectly ``` Write at 0x00c0001c7418 by goroutine 796: github.com/tendermint/tendermint/consensus.TestStartNextHeightCorrectly() /go/src/github.com/tendermint/tendermint/consensus/state_test.go:1296 +0xad testing.tRunner() /usr/local/go/src/testing/testing.go:827 +0x162 Previous read at 0x00c0001c7418 by goroutine 858: github.com/tendermint/tendermint/consensus.(*ConsensusState).addVote() /go/src/github.com/tendermint/tendermint/consensus/state.go:1631 +0x1366 github.com/tendermint/tendermint/consensus.(*ConsensusState).tryAddVote() /go/src/github.com/tendermint/tendermint/consensus/state.go:1476 +0x8f github.com/tendermint/tendermint/consensus.(*ConsensusState).handleMsg() /go/src/github.com/tendermint/tendermint/consensus/state.go:667 +0xa1e github.com/tendermint/tendermint/consensus.(*ConsensusState).receiveRoutine() /go/src/github.com/tendermint/tendermint/consensus/state.go:628 +0x794 Goroutine 796 (running) created at: testing.(*T).Run() /usr/local/go/src/testing/testing.go:878 +0x659 testing.runTests.func1() /usr/local/go/src/testing/testing.go:1119 +0xa8 testing.tRunner() /usr/local/go/src/testing/testing.go:827 +0x162 testing.runTests() /usr/local/go/src/testing/testing.go:1117 +0x4ee testing.(*M).Run() /usr/local/go/src/testing/testing.go:1034 +0x2ee main.main() _testmain.go:214 +0x332 Goroutine 858 (running) created at: github.com/tendermint/tendermint/consensus.(*ConsensusState).startRoutines() /go/src/github.com/tendermint/tendermint/consensus/state.go:334 +0x221 github.com/tendermint/tendermint/consensus.startTestRound() /go/src/github.com/tendermint/tendermint/consensus/common_test.go:122 +0x63 github.com/tendermint/tendermint/consensus.TestStateFullRound…
