When set to true, an invalid transaction will be kept in the cache (this may help some applications to protect against spam).
NOTE: this is a temporary config option. The more correct solution would be to add a TTL to each transaction (i.e. CheckTx may return a TTL in ResponseCheckTx).
Closes: #5751
`abci.Client`:
- Sync and Async methods now accept a context for cancellation
* grpc client uses context to cancel both Sync and Async requests
* local client ignores context parameter
* socket client uses context to cancel Sync requests and to drop Async requests before sending them if context was cancelled prior to that
- Async methods return an error
* socket client returns an error immediately if queue is full for Async requests
* local client always returns nil error
* grpc client returns an error if context was cancelled before we got response or the receiving queue had a space for response (do not confuse with the sending queue from the socket client)
- specify clients semantics in [doc.go](https://raw.githubusercontent.com/tendermint/tendermint/27112fffa62276bc016d56741f686f0f77931748/abci/client/doc.go)
`mempool.TxInfo`
- add optional `Context` to `TxInfo`, which can be used to cancel `CheckTx` request
Closes#5190
In order to have more control over the mempool implementation,
introduce a new exported function RemoveTxByKey.
Export also TxKey() and TxKeySize. Use TxKeySize const instead of
sha256.size, so future changes on the hash function won't break the API.
Allows using a TxKey (32 bytes reference) as parameter instead of
the complete array set. So the application layer does not need to
keep track of the whole transaction but only of the sha256 hash (32 bytes).
This function is useful when mempool.Recheck is disabled.
Allows the Application layer to implement its own cleaning mechanism
without having to re-implement the whole mempool interface.
Mempool.Update() would probably also need to change from txBytes to txKey,
but that would require to change the Interface thus will break backwards
compatibility. For now RemoveTxByKey() looks like a good compromise,
it won't break anything and will help to solve some mempool issues from the
application layer.

Contributes to #3262
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

* move Mempool interface into mempool package
Refs #2659
Breaking changes in the mempool package:
- Mempool now an interface
- old Mempool renamed to CListMempool
Breaking changes to state package:
- MockMempool moved to mempool/mock package and renamed to Mempool
- Mempool interface moved to mempool package
* assert CListMempool impl Mempool
* gofmt code
* rename MempoolReactor to Reactor
- combine everything into one interface
- rename TxInfo.PeerID to TxInfo.SenderID
- unexpose MempoolReactor.Mempool
* move mempool mock into top-level mock package
* add a fixme
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.
* change node#Mempool to return interface
* save commit = new reactor arch
* Revert "save commit = new reactor arch"
This reverts commit 1bfceacd9d.
* require CListMempool in mempool.Reactor
* add two changelog entries
* fixes after my own review
* quote interfaces, structs and functions
* fixes after Ismail's review
* make node's mempool an interface
* make InitWAL/CloseWAL methods a part of Mempool interface
* fix merge conflicts
* make node's mempool an interface
