Emmanuel Odeke	15ef57c6d0	types: TxEventBuffer.Flush now uses capacity preserving slice clearing idiom Fixes https://github.com/tendermint/tendermint/issues/1189 For every TxEventBuffer.Flush() invoking, we were invoking a: b.events = make([]EventDataTx, 0, b.capacity) whose intention is to innocently clear the events slice but maintain the underlying capacity. However, unfortunately this is memory and garbage collection intensive which is linear in the number of events added. If an attack had access to our code somehow, invoking .Flush() in tight loops would be a sure way to cause huge GC pressure, and say if they added about 1e9 events maliciously, every Flush() would take at least 3.2seconds which is enough to now control our application. The new using of the capacity preserving slice clearing idiom takes a constant time regardless of the number of elements with zero allocations so we are killing many birds with one stone i.e b.events = b.events[:0] For benchmarking results, please see https://gist.github.com/odeke-em/532c14ab67d71c9c0b95518a7a526058 for a reference on how things can get out of hand easily.	7 years ago

Anton Kaliaev	5f3048bd09	call FlushSync before calling CommitSync if we call it after, we might receive a "fresh" transaction from `broadcast_tx_sync` before old transactions (which were not committed). Refs #1091 ``` Commit is called with a lock on the mempool, meaning no calls to CheckTx can start. However, since CheckTx is called async in the mempool connection, some CheckTx might have already "sailed", when the lock is released in the mempool and Commit proceeds. Then, that spurious CheckTx has not yet "begun" in the ABCI app (stuck in transport?). Instead, ABCI app manages to start to process the Commit. Next, the spurious, "sailed" CheckTx happens in the wrong place. ```	7 years ago

Adrian Brink	32311acd01	Vulnerability in light client proxy (#1081 ) * Vulnerability in light client proxy When calling GetCertifiedCommit the light client proxy would call Certify and even on error return the Commit as if it had been correctly certified. Now it returns the error correctly and returns an empty Commit on error. * Improve names for clarity The lite package now contains StaticCertifier, DynamicCertifier and InqueringCertifier. This also changes the method receivers from one letter to two letter names, which will make future refactoring easier and follows the coding standards. * Fix test failures * Rename files * remove dead code	7 years ago
