Calling ensurePeers outside of ensurePeersRoutine can lead to nodes
disconnecting from us due to "sent next PEX request too soon" error.
Solution is to just dial addrs we got from src instead of calling
ensurePeers.
Refs #2093Fixes#3338
* Move GenesisDocProvider and DefaultGenesisDocProviderFunc
GenesisDocProvider, being a provider of *types.GenesisDoc, makes sense
to be part of the types package.
DefaultGenesisDocProviderFunc, which relies on *config.Config to produce
a types.GenesisDocProvider, makes sense being part of the config
package.
* Add aliases to avoid breaking node package API
* Revert to original structure
After discussion, it appears as though the best place for the relocated
structures is still in the node package. This means that for the v0.31.6
release and into the future, there will be no changes two these two
entities' APIs.
* update changelog
* Update changelog
- less detail about internal stuff like the `mempool`
- focus BUG FIX entries more on what was fixed rather than how
* minor cleanup.
- remove entry for GenesisDocProvider, it's being undone
* minor fix
* Peer behaviour test tweaks:
Address the remaining test issues mentioned in ##3552 notably:
+ switch to p2p_test package
+ Use `Error` instead of `Errorf` when not using formatting
+ Add expected/got errors to
`TestMockPeerBehaviourReporterConcurrency` test
* Peer behaviour equal behaviours test
+ slices of PeerBehaviours should be compared as histograms to
ensure they have the same set of PeerBehaviours at the same
freequncy.
* TestEqualPeerBehaviours:
+ Add tests for the equivalence between sets of PeerBehaviours
* Allow testnet hostnames to be overridden
This allows one to specify the `--hostname` flag multiple times, each
time providing an additional custom hostname for a respective peer
(validator or non-validator). This overrides any of the
`--hostname-prefix` or `--starting-ip-address` flags.
The string array approach is taken instead of the string slice approach
(see the pflag docs:
https://godoc.org/github.com/spf13/pflag#StringArray) because the string
slice approach (a comma-separated string) doesn't allow for cleaner
multi-line BASH scripts - where this feature is intended to be used.
* Reorder conditional for clarity with simpler earlier return
* Allow for specifying peer hostname suffix
* Quote values in help strings for greater clarity
* Fix command switch
* Add CHANGELOG_PENDING entry for PR
* Allow for unique monikers
The current approach to generating monikers for testnet nodes assigns
the local hostname of the machine on which the testnet config was
generated to all nodes. This results in the same moniker for each and
every node.
This commit makes use of the supplied `--hostname-prefix` and
`--hostname-suffix`, or `--hostname` parameters to generate unique
monikers for each node. Alternatively, another parameter
(`--random-monikers`) allows one to forcibly override all of the other
options with random hexadecimal strings.
* Update CHANGELOG_PENDING entry for new command line switch
* fix peer state init to late
Peer does not have a state yet. We set it in AddPeer.
We need an new interface before mconnection is started
* pex message to soon
fix reconnection pex send too fast,
error is caused lastReceivedRequests is still
not deleted when a peer reconnected
* add test case for initpeer
* add prove case
* remove potentially infinite loop

* fix pex reactor

* use waitUntilSwitchHasAtLeastNPeers func
* bring back timeouts
* Test to ensure Receive panics if InitPeer has not been called
* p2p/pex: consult seeds in crawlPeersRoutine
This changeset alters the startup behavior for crawlPeersRoutine. Previously
the routine would crawl a random selection of peers on startup. For a
new seed node, there are no peers. As a result, new seed nodes are unable
to bootstrap themselves with a list of peers until another node with a list
of peers connects to the seed. If this node relies on the seed node for peers,
then the two will not discover more peers.
This changeset makes the startup behavior for crawlPeersRoutine connect to
any seed nodes. Upon connecting, a request for peers will be sent to the seed node
thus helping bootstrap our seed node.

NOTE: batch does not have to be safe for concurrent access. Delete may
be slow, but given it should not be used often, it's ok.

* mempool: remove only valid (Code==0) txs on Update
so evil proposers can't drop valid txs in Commit stage.
Also remove invalid (Code!=0) txs from the cache so they can be
resubmitted.
Fixes#3322@rickyyangz:
In the end of commit stage, we will update mempool to remove all the txs
in current block.
// Update mempool.
err = blockExec.mempool.Update(
block.Height,
block.Txs,
TxPreCheck(state),
TxPostCheck(state),
)
Assum an account has 3 transactions in the mempool, the sequences are
100, 101 and 102 separately, So an evil proposal can only package the
101 and 102 transactions into its proposal block, and leave 100 still in
mempool, then the two txs will be removed from all validators' mempool
when commit. So the account lost the two valid txs.
@ebuchman:
In the longer term we may want to do something like #2639 so we can
validate txs before we commit the block. But even in this case we'd only
want to run the equivalent of CheckTx, which means the DeliverTx could
still fail even if the CheckTx passes depending on how the app handles
the ABCI Code semantics. So more work will be required around the ABCI
code. See also #2185
* add changelog entry and tests
* improve changelog message
* reformat code
