As per #2127, this refactors the RequestCheckTx ProtoBuf struct to allow for a flag indicating whether a query is a recheck or not (and allows for possible future, more nuanced states).
In order to pass this extended information through to the ABCI app, the proxy.AppConnMempool (and, for consistency, the proxy.AppConnConsensus) interface seems to need to be refactored along with abcicli.Client.
And, as per this comment, I've made the following modification to the protobuf definition for the RequestCheckTx structure:
enum CheckTxType {
New = 0;
Recheck = 1;
}
message RequestCheckTx {
bytes tx = 1;
CheckTxType type = 2;
}
* Refactor ABCI CheckTx to notify of recheck
As per #2127, this refactors the `RequestCheckTx` ProtoBuf struct to allow for:
1. a flag indicating whether a query is a recheck or not (and allows for
possible future, more nuanced states)
2. an `additional_data` bytes array to provide information for those more
nuanced states.
In order to pass this extended information through to the ABCI app, the
`proxy.AppConnMempool` (and, for consistency, the
`proxy.AppConnConsensus`) interface seems to need to be refactored.

* 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

TxsFront should not be a part of the Mempool interface
because it leaks implementation details. Instead, we need to come up
with general interface for querying the mempool so the MempoolReactor
can fetch and broadcast txs to peers.

Refs #3306, irisnet@fdbb676
I ran an irishub validator. After the validator node ran several days, I dump the whole goroutine stack. I found that there were hundreds of broadcastTxRoutine. However, the connected peer quantity was less than 30. So I belive that there must be broadcastTxRoutine leakage issue.
According to my analysis, I think the root cause of this issue locate in below code:
select {
case <-next.NextWaitChan():
// see the start of the for loop for nil check
next = next.Next()
case <-peer.Quit():
return
case <-memR.Quit():
return
}
As we know, if multiple paths are avaliable in the same time, then a random path will be selected. Suppose that next.NextWaitChan() and peer.Quit() are both avaliable, and next.NextWaitChan() is chosen.
// send memTx
msg := &TxMessage{Tx: memTx.tx}
success := peer.Send(MempoolChannel, cdc.MustMarshalBinaryBare(msg))
if !success {
time.Sleep(peerCatchupSleepIntervalMS * time.Millisecond)
continue
}
Then next will be non-empty and the peer send operation won't be success. As a result, this go routine will be track into infinite loop and won't be released.
My proposal is to check peer.Quit() and memR.Quit() in every loop no matter whether next is nil.
Closes#1798
This is done by making every mempool tx maintain a list of peers who its received the tx from. Instead of using the 20byte peer ID, it instead uses a local map from peerID to uint16 counter, so every peer adds 2 bytes. (Word aligned to probably make it 8 bytes)
This also required resetting the callback function on every CheckTx. This likely has performance ramifications for instruction caching. The actual setting operation isn't costly with the removal of defers in this PR.

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().
Within every tx in the mempool, we store a 64 bit counter,
as an index for when it was inserted into the mempool.
This counter doesn't really serve any purpose.
It was likely added for debugging at one point,
Removing the counter reclaims memory,
which enables greater mempool sizes / mitigates resources at the same size.
Closes#2835
* use READ lock/unlock in ConsensusState#GetLastHeight
Refs #2721

* panic if peer has no state
https://github.com/tendermint/tendermint/issues/2721#issuecomment-435347165
It's confusing that sometimes we check if peer has a state, but most of
the times we expect it to be there
1. add79700b5/mempool/reactor.go (L138)
2. add79700b5/rpc/core/consensus.go (L196) (edited)
I will change everything to always assume peer has a state and panic
otherwise
that should help identify issues earlier
* abci/localclient: extend lock on app callback
App callback should be protected by lock as well (note this was already
done for InitChainAsync, why not for others???). Otherwise, when we
execute the block, tx might come in and call the callback in the same
time we're updating it in execBlockOnProxyApp => DATA RACE

```
* consensus: use read lock in Receive#VoteMessage
* use defer to unlock mutex because application might panic
* use defer in every method of the localClient
* add a changelog entry
* drain channels before Unsubscribe(All)
Read 55362ed766/libs/pubsub/pubsub.go (L13)
for the detailed explanation of the issue.
We'll need to fix it someday. Make sure to keep an eye on
https://github.com/tendermint/tendermint/blob/master/docs/architecture/adr-033-pubsub.md
* retry instead of panic when peer has no state in reactors other than consensus
in /dump_consensus_state RPC endpoint, skip a peer with no state
* rpc/core/mempool: simplify error messages
* rpc/core/mempool: use time.After instead of timer
also, do not log DeliverTx result (to be consistent with other memthods)
* unlock before calling the callback in reqRes#SetCallback
* fix amino overhead computation for Tx:
- also count the fieldnum / typ3
- add method to compute overhead per Tx
- slightly clarify comment on MaxAminoOverheadForBlock
- add tests
* fix TestReapMaxBytesMaxGas according to amino overhead
* fix TestMempoolFilters according to amino overhead
* address review comments:
- add a note about fieldNum = 1
- add forgotten godoc comment
* fix and use sm.TxPreCheck
* fix test
* remove print statement
* mempool: ErrPreCheck and more log info
* change Pre/PostCheckFunc to return errors
also, continue execution when checking txs in mempool_test if
err=PreCheckErr
This also refactors the prior mempool to filter to be known as
"precheck filter" and this new filter is called "postcheck filter"
This PR also fixes a bug where the precheck filter previously didn't
account for the amino overhead, which could a maliciously sized tx to
halt blocks from getting any txs in them.
* Move maxGas outside of function definition to avoid race condition
* Type filter funcs and make public
* Use helper method for post check
* Remove superfluous Filter suffix
* Move default pre/post checks into package
* Fix broken references
* Fix typos
* Expand on examples for checks
* follow up to removing some consensus params Refs #2382
* change args type to int64 in state#makeParams
* make valsCount and evidenceCount ints again
* MaxEvidenceBytesPerBlock: include magic number in godoc
* [spec] creating a proposal
* test state#TxFilter
* panic if MaxDataBytes is less than 0
* fixes after review
* use amino#UvarintSize to calculate overhead
0c74291f3b/encoder.go (L85-L90)
* avoid cyclic imports
* you can do better Go, come on
* remove testdouble package
* Make mempool aware of MaxGas requirement
* update spec
* Add tests
* Switch GasWanted from kv store to persistent kv store
* Fix typo in test name
* switch back to using kvstore, not persistent kv store
* mempool: Store txs by hash inside of cache
This allows for large cachesizes, without fear of the memory
consumption growing rapidly.
* (squash this) rename hashedTx -> txHash
* mempool: Keep cache hashmap and linked list in sync
This removes bugs with the linked list being full, but hashmap empty
* address PR comments
* switch clist back to list
