Roman Khimov	236438d799	core: do MPT compaction every once in a while We need to compact our in-memory MPT from time to time, otherwise it quickly fills up all available memory. This raises two obvious quesions --- when to do that and to what level do that. As for 'when', I think it's quite easy to use our regular persistence interval as an anchor (and it also frees up some memory), but we can't do that in the persistence routine itself because of synchronization issues (adding some synchronization primitives would add some cost that I'd also like to avoid), so do it indirectly by comparing persisted and current height in `storeBlock`. Choosing proper level is another problem, but if we're to roughly estimate one full branch node to use 1K of memory (usually it's way less than that) then we can easily store 1K of these nodes and that gives us a depth of 10 for our trie.

Roman Khimov	58b7e16e0e	core: fix PrevHash calculation for MPTRoot This was differing from C# notion of PrevHash.

Evgenii Stratonikov	6ca22027d5	mpt: implement (*Trie).Collapse() Because trie size is rather big, it can't be stored in memory. Thus some form of caching should also be implemented.

Roman Khimov	ae9658a108	dao: migrate nep5 balances with the contract Fixes #1144. It's quite simple approach, we just update balance info right upon contract migration. It will slow down migration transactions, but it takes about 1-2 seconds to Seek through balances at mainnet's 3.8M, so the approach should still work good enough. The other idea was to make lazy updates (maintaining contract migration map), but it's more complicated to implement (and implies that a balance get might also do a write). There also is a concern about memory usage, it can give a spike of some tens of megabytes, but that also is considered to be acceptable.	2020-07-17 19:03:12 +03:00

It's not good for notifications because third-party clients would probably expect to see the same format. Also, using completely different Block representation is probably making our client a bit weaker as this representation is harder to use with other neo-go components. So use the same approach we took for Transactions and wrap block.Block which is to be serialized in proper way.

In this situation an attemmpt to call the corresponding native contracts methods (e.g. transfer native GAS) leads to contract invocation failure, as far as `nep5TokenNative.incBalance` method is nil.

Anna Shaleva	4ebac5a069	core: fix bug in nep5 notifications handling Native contracts deployment creates `Transfer` notifications and adds them into interop context. However, these notifications were not stored for two reasons: 1. typo in `Transfer` (so these notifications were not recognised during processing of the invocation tx in (*Blockchain).storeBlock(...) method) 2. these notifications have `from` adress setted to null, so conversion to []byte fails.

Initial minting should be done in Neo.Native.Deploy because it generates notification that should have proper transaction context. RegisterNative() shouldn't exist as a public method, native contracts are only registered at block 0 and they can do it internally, no outside user should be able to mess with it. Move some structures from `native` package to `interop` also to avoid circular references as interop.Context has to have a list of native contracts (exposing them via Blockchainer is again too dangerous, it's too powerful tool).	2020-04-27 12:30:39 +03:00

Anna Shaleva	9b03f968b1	core: fixe FreeGasLimit constraint Lack of FreeGasLimit in privnet leads to gas limit exceeding in case of transactions with small amount of GAS to be used for invoke operation (< real cost of the transaction).

Roman Khimov	1133bbe584	mempool: remove unverified transactions pool Our mempool only contains valid verified transactions all the time, it never has any unverified ones. Unverified pool made some sense for quick unverifying after the new block acceptance (and gradual background reverification), but reverification needs some non-trivial locking between blockchain and mempool and internal mempool state locking (reverifying tx and moving it between unverified and verified pools must be atomic). But our current reverification is fast enough (and has all the appropriate locks), so bothering with unverified pool makes little sense.	2020-02-06 15:45:16 +03:00
Roman Khimov	b675903f52	mempool/core: redesign mempool dances on block acceptance We not only need to remove transactions stored in the block, but also invalidate some potential double spends caused by these transactions. Usually new block contains a substantial number of transactions from the pool, so it's easier to make one pass over it only keeping valid items rather than remove them one by one and make an additional pass to recheck inputs/witnesses.	2020-02-06 15:45:16 +03:00

Roman Khimov	794027a90b	mempool: use one slice for both priorities It doesn't harm as we have transactions naturally ordered by fee anyway and it makes managing them a little easier. This also makes slices store item itself instead of pointers to it which reduces the pressure on the memory subsystem.	2020-02-06 15:43:45 +03:00
Roman Khimov	325bea3fa9	mempool: cache Feer invocation results in the item They shouldn't depend on the chain state and for the same transaction they should always produce the same result. Thus, it makes no sense recalculating them over and over again.	2020-02-06 15:41:56 +03:00

Roman Khimov	a7457d08a1	vm/core: add ID support for SYSCALL, redo interop registration This solves two problems: * adds support for shortened SYSCALL form that uses IDs (similar to #434, but for NEO 2.0, supporting both forms), which is important for compatibility with C# node and mainnet chain that uses it from some height * reworks interop plugging to use callbacks rather than appending to the map, these map mangling functions are clearly visible in the VM profiling statistics and we want spawning a VM to be fast, so it makes sense optimizing it. This change moves most of the work to the init() phase making VM setup cheaper. Caveats: * InteropNameToID accepts `[]byte` because that's the thing we have in SYSCALL processing and that's the most often usecase for it, it leads to some conversions in other places but that's acceptable because those are either tests or init() * three getInterop functions are: `getDefaultVMInterop`, `getSystemInterop` and `getNeoInterop` Our 100K (1.4M->1.5M) block import time improves by ~4% with this change.	2019-12-19 13:35:42 +03:00
