Roman Khimov	2d0ad30fcf	vm: rework Map with internal slice representation Which makes iterating over map stable which is important for serialization and and even fixes occasional test failures.

Roman Khimov	3dbe549a61	smartcontract: store MapType Parameter as a slice of KV pairs Fixes #809. Basically, there are three alternative approaches to fixing it: * allowing both []byte and string for ByteArrayType value minimal invasion into existing code, but ugly as hell and will probably backfire at some point * storing string values in ByteArrayType incurs quite a number of type conversions (and associated data copying), though note that these values are not changed usually, so dynamic properties of []byte are almost irrelevant here * storing only []byte values in ByteArrayType makes it impossible to use them as map keys which can be solved in several ways: - via an interface (Marshalable) which is good, but makes testing and comparing values in general harder, because of keys mismatch - using serialized Parameter as a key (in a string) which will need some additional marshaling/unmarshaling - converting MapType from map to a slice of key-value pairs not a bad idea as we don't use this map as a map really, the type itself is all about input/output for real VM types and this approach is also a bit closer to JSON representation of the Map	2020-04-01 19:21:00 +03:00
Evgenii Stratonikov	a43c9b9246	compiler: calculate stack size more precisely When calculating number of local variables, only defining assignments (i.e. via `:=`) must be taken into account.	2020-04-01 17:36:19 +03:00

Roman Khimov	665bf78d11	vm: make map serialization more compatible with C# C# pushes value and key to the stack of non-serialized items, so key gets serialized first followed by value. Fixes #806. Notice though that neither IDictionary in C#, nor map in Go have elements ordered, so we can easily get a difference in KV pairs order and it would be impossible to fix.	2020-03-28 17:25:42 +03:00
Roman Khimov	4758de71ec	storage: optimize (*MemCachedStore).Persist for memory-backed ps Most of the time it's persisted into the MemoryStore or MemCachedStore, when that's the case there is no real need to go through the Batch mechanism as it incurs multiple copies of the data. Importing 1.5M mainnet blocks with verification turned off, before: real 12m39,484s user 20m48,300s sys 2m25,022s After: real 11m15,053s user 18m2,755s sys 2m4,162s So it's around 10% improvement which looks good enough.	2020-03-28 17:21:50 +03:00

Roman Khimov	c258adb532	core: move spent coin management out of the inner storeBlock loop prevHash == input.PrevHash, so make less DB accesses and more real work. Fix some bugs along the way: * spentCoins structure may already be present in the DB when persisting TX, there is nothing wrong with that and we shouldn't overwrite it * it's only used for NEO and only to check for claim validity. Thus, when processing claim tx the corresponding spentCoins should always be present in the DB	2020-02-25 17:21:09 +03:00

Roman Khimov	f9c6a0d77c	core: make voting choose the best validators They need to be sorted in order for voting system to work.	2020-02-13 13:07:34 +03:00
Roman Khimov	2ff7ceb8cf	core: properly update validator votes for Account descriptor ValidatorsCount is not implemented yet, but we need to update validators properly, adding account's vote to their votes count.	2020-02-13 13:07:34 +03:00
Roman Khimov	8310b76d28	core: properly save votes when processing Account descriptor They were ignored basically.	2020-02-13 13:07:34 +03:00
Roman Khimov	807309a0de	core/state: only drop unregistered non-voted validators Simple as that: UnregisteredAndHasNoVotes != !RegisteredAndHasVotes Registered validators should stay in the DB, we might be in the process of updating votes for them and that starts with subtraction.	2020-02-13 13:07:34 +03:00
Evgeniy Kulikov	64e325d9af	Update tests for `getblock` action - replace `GetBlockResponse.Result` with `wrappers.Block` - update `getblock` checker and add more assets	2020-02-12 21:58:43 +03:00
Roman Khimov	32a064aa31	keys: add Cmp method to PublicKey It can be used by code that doesn't operate with PublicKeys, but still needs to be able to compare keys for some purposes.	2020-02-12 21:27:40 +03:00
Roman Khimov	38d0efc96c	core: fix Registered state descriptor processing It has simple boolean value encoded, no `strconv` needed (it actually chokes on such input).	2020-02-12 21:27:40 +03:00
Roman Khimov	141553da4c	keys: fix PublicKeys decoding It changes the slice, thus it has to work via a pointer.	2020-02-12 21:23:28 +03:00
Roman Khimov	803fb39bb0	transaction: fix wrong state descriptor serdes Wrong field order.	2020-02-12 21:23:28 +03:00
Evgeniy Kulikov	41ebf12eb3	Update `getblock` RPC action response	2020-02-12 19:43:51 +03:00
Evgenii Stratonikov	0a894db7f8	storage: add Exists flag to KeyValue in batch Set Exists flag if an item with the specified key was already present in storage before persisting.	2020-02-12 12:16:31 +03:00
Evgenii Stratonikov	b1d9e1132d	cli: dump storage changes into JSON files	2020-02-12 12:16:31 +03:00
Evgenii Stratonikov	fb9af98179	storage: implement GetBatch() to view storage changes GetBatch returns changes to be persisted.	2020-02-12 12:16:31 +03:00
Evgenii Stratonikov	8ea3ef0b62	compiler: process empty []byte{} literals as ByteArrays It is wrong to count an empty byte slice as an Array.	2020-02-12 12:16:15 +03:00
Evgenii Stratonikov	32bce30777	compiler: support sub-slicing	2020-02-12 12:16:15 +03:00
Evgenii Stratonikov	310f7449d7	compiler: support for-range loops	2020-02-12 12:16:04 +03:00
Evgenii Stratonikov	ae03560589	compiler: support initializing struct fields from a variable While initializing a struct, it is a top item on ALTSTACK. This means that if we need to load a local variable, DUPFROMALTSTACK won't longer push an array of locals on stack but rather a currently initializing struct. Closes #656.	2020-02-12 12:15:54 +03:00
Evgenii Stratonikov	3e84f2bdf8	compiler: rewrite jump targets properly Old implementation could view 0x62 byte in a script as a JMP instruction irregardless of whether it is a real opcode or a part of a parameter of another instruction. In this commit instructions are decoded together with parameters during jump label rewriting.	2020-02-12 10:58:53 +03:00
Roman Khimov	d3badc3f97	consensus: log more like neo-cli, update dbft	2020-02-11 18:02:13 +03:00
Roman Khimov	38de2af073	Merge pull request #655 from nspcc-dev/fix-mempool-deadlock-on-reverification core: get transactions from dao when mempool should not be used	2020-02-11 13:34:23 +03:00
Roman Khimov	292051d8df	core: get transactions from dao when mempool should not be used All of these places deal strictly with the chain and shouldn't ever be bothered with mempool.

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). Solution: Fixed constraint in case when FreeGasLimit == 0. So now we are able to perform transactions in privnet with FreeGasLimit = 0 for free.	2020-02-10 18:07:19 +03:00

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	b567ce86ac	mempool: implement insertion to sorted slice Which is way faster than sort.Sort'ing things all the time.	2020-02-06 15:44:18 +03:00
Roman Khimov	35183b6dba	mempool: reverse the order of sorted slice Chopping off the last element of the slice if way easier than doing it with the first one.	2020-02-06 15:44:16 +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	e01bfeeb4d	mempool: remove lock indirection from the Pool After the `f0bb886be3` with all methods of Pool being pointer-based it makes no sense having this lock as a pointer.	2020-02-06 15:41:56 +03:00
Roman Khimov	a928ad9cfa	mempool: make item an internal thing of mempool package Nobody outside should care about these details, mempool operates on transactions and that's it.	2020-02-06 15:41:56 +03:00

Roman Khimov	b9b77ac1be	network: fix block relaying, don't spit out useless errors We can only add one block of the given height and we have two competing goroutines to do that --- consensus and block queue.
