Roman Khimov	19c21452c9	interop/account: update and extend documentation	2020-05-26 19:51:20 +03:00
alexvanin	aca6f2f3ad	rpc/client: handle client creation error in new wsclient Client returns error if it can't parse endpoint string. WSClient should check client error or there could be panic at `cl.cli = nil` expression.	2020-05-26 11:36:47 +03:00
Roman Khimov	29e66925aa	rpc/client: deduplicate block/header tests a bit The same data is copied at least twice here. Also use this block for header test making it a bit more convenient.	2020-05-26 11:36:47 +03:00
Roman Khimov	5432530df4	result: use witnesses field in result.Header JSON Follow new Neo 3.0 standard for these outputs.	2020-05-26 11:36:47 +03:00
Roman Khimov	7633439845	rpc/block: rework the way Block is JSONized Our block.Block was JSONized in a bit different fashion than result.Block in its NextConsensus and Index fields. 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. Fix `Script` JSONization along the way, 3.0 node wraps it within `witnesses`.	2020-05-26 11:36:47 +03:00
Roman Khimov	393ce1c230	rpc/server: add notification filters And check state string correctness on unmarshaling.	2020-05-26 11:36:47 +03:00
Roman Khimov	2dc16c0694	transaction: add json.Unmarshaler to Attribute It actually was missing and it might affect Transaction conversion to/from JSON.	2020-05-26 11:36:47 +03:00
Roman Khimov	725b47ddef	rpc/client: add support for notification filters Differing a bit from #895 draft specification, we won't add `sender` or `cosigner` to `transaction_executed`.	2020-05-26 11:36:47 +03:00
Roman Khimov	c4c080d240	rpc: add subscriber queue overflow check Server-side test is added, but disabled because of its unreliability.	2020-05-26 11:36:47 +03:00
Roman Khimov	44ae9086b6	core: improve and fix locking in storeBlock Getting batch, updating Prometheus metrics and pushing events doesn't require any locking: batch is a local cache batch that no one outside cares about, Prometheus metrics are not critical to be in perfect sync and events are asynchronous anyway. Native contracts also don't require any locks and they should be processed before dumping storage changes.	2020-05-26 11:36:47 +03:00
Roman Khimov	bef14977a2	rpc/client: add notifications support for WSClient It differs from #895 design in that we have Notifications channel always exposed as WSClient field, probably it simplifies things a little.	2020-05-26 11:36:47 +03:00
Roman Khimov	fc22a46a4c	rpc/server: add notification subscription Note that the protocol differs a bit from #895 in its notifications format, to avoid additional server-side processing we're omitting some metadata like: * block size and confirmations * transaction fees, confirmations, block hash and timestamp * application execution doesn't have ScriptHash populated Some block fields may also differ in encoding compared to `getblock` results (like nonce field). I think these differences are unnoticieable for most use cases, so we can leave them as is, but it can be changed in the future.	2020-05-26 11:36:47 +03:00
Roman Khimov	03ecab5eec	smartcontract: add JSON marshal/unmarshal for InteropType We actually have to do that in order to answer getapplicationlog requests for transactions that leave some interop items on the stack. It follows the same logic our binary serializer/deserializes does leaving the type and stripping the value (whatever that is).	2020-05-25 00:27:39 +03:00
Roman Khimov	612500ed96	rpc/server: start and shutdown Server in tests It will be important for proper subscription testing and it doesn't hurt even though technically we've got two http servers listening after this change (one is a regular Server's http.Server and one is httptest's Server). Reusing rpc.Server would be nice, but it requires some changes to Start sequence to start Listener with net.Listen and then communicate back its resulting Addr. It's not very convenient especially given that no other code needs it, so doing these changes just for a bit cleaner testing seems like and overkill. Update config appropriately. Update Start comment along the way.	2020-05-25 00:27:39 +03:00
Roman Khimov	b7d2b659b4	network: get blocks directly from the chain for rebroadcasting Simplify network<->consensus relations, also broadcast blocks received by other means like RPC.	2020-05-25 00:27:39 +03:00
Roman Khimov	462022bbdd	consensus: remove OnNewBlock(), use Blockchain subscription Get new blocks directly from the Blockchain. It may lead to some duplications (as we'll also receive our own blocks), but at the same time it's more correct, because technically we can also get blocks via other means besides network server like RPC (submitblock call). And it simplifies network server at the same time.	2020-05-25 00:27:39 +03:00
Roman Khimov	3ca71d5e8d	core: add Blockchain event subscription mechanism A deep internal part of #895. Blockchainer interface is also extended for various uses of these methods.	2020-05-25 00:27:39 +03:00

Evgenii Stratonikov	673e6c84d1	vm/tests: preserve order when decoding Map item. When using Go's `map` for decoding, order can change from time to time, while we may want to check it too. Use custom decoder for saving items in order.	2020-05-22 14:17:15 +03:00

Anna Shaleva	c7a040ff81	core: fix bug with native contracts methods initialisation `NewNEO()` and `NewGAS()` methods are trying to initialise both `onPersist` and `incBalance` methods of NEO and GAS AFTER nep5TokenNative is set to the VALUE of created nep5 token. 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. Fixed this by initializing both `onPersist` and `incBalance` methods before getting the value of nep5 contract.	2020-05-20 23:16:04 +03:00
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. Same thing could happen with `to`. Related C# issue: https://github.com/neo-project/neo/issues/1646 For now, made both `transfer` and `Transfer` valid.	2020-05-20 23:16:04 +03:00

Roman Khimov	7287c01bd0	rpc/server: rework submitblock empty test The original intention here was to check for server reaction in presence of validation errors (response.ErrValidationFailed) and it was very easy to make validation fail for block without transactions in Neo 2. But in Neo 3 transactionless blocks are perfectly valid (see `29d321b5e1`) which broke this test even though we didn't see it until websocket addition (which required `8cec6694ae` to make this test work initially). So make a valid block and then spoil its verification script.	2020-05-06 14:20:35 +03:00

Anna Shaleva	2ec1d76320	compiler: add ability to generate .abi.json file A part of integration with NEO Blockchain Toolkit (see #902). To be able to deploy smart-contract compiled with neo-go compiler via NEO Express, we have to generate additional .abi.json file. This file contains the following information: - hash of the compiled contract - smart-contract metadata (title, description, version, author, email, has-storage, has-dynamic-invoke, is-payable) - smart-contract entry point - functions - events However, this .abi.json file is slightly different from the one, described in manifest.go, so we have to add auxilaury stractures for json marshalling. The .abi.json format used by NEO-Express is described [here](https://github.com/neo-project/neo-devpack-dotnet/blob/master/src/Neo.Compiler.MSIL/FuncExport.cs#L66).	2020-05-04 08:37:39 +03:00

Roman Khimov	30836ca69b	core/native: untangle native contracts initialization The notion of NativeContractState shouldn't ever existed, native contract is a contract and its state is saved as regular contract state which is critical because we'll have MPT calculations over this state soon. 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

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

Roman Khimov	23464401bc	core/state: merge spent and unspent coins state, use it to store more things This change reduces pressure on DB by doing the following things: * not storing additional KV pair for SpentCoin * storing Output right in the UnspentCoin, thus eliminating the need to get a full transaction from DB At the same time it makes UnspentCoin more fat and hot, but it should probably worth it. Also drop `GetUnspentCoinStateOrNew` as it shouldn't ever existed, UTXOs can't come out of nowhere. 1.5M block import time (VerifyBlocks disabled) on AMD Ryzen 5 1600/16GB/HDD, before: real 302m9.895s user 96m17.200s sys 13m37.084s after: real 159m16.551s user 69m58.279s sys 7m34.334s So it's almost two-fold which is a great improvement.	2020-03-11 12:40:02 +03:00

Roman Khimov	bba8ac15ff	rpc: introduce proper type for sendrawtransaction, drop useless types sendrawtransaction just returns a bool, sendtoaddress returns a proper transaction and that should be the same as the one we have in TransactionOutputRaw.	2020-02-21 15:12:04 +03:00

Roman Khimov	f330f2f40b	rpc: separate out request and response structures Mostly as is, no real effort done yet to optimize them, so there are still a lot of duplicates there, but at least we sort them out into different smaller packages.	2020-02-21 15:12:04 +03:00

Roman Khimov	bfa2d54e16	rpc: move validateAddress() function from wrappers into server It's a server implementation detail, it has nothing to do with the data format itself. It also makes no sense exporing it.	2020-02-21 15:12:04 +03:00
Roman Khimov	72a62f1292	result: add trivial test for peers management functions	2020-02-21 15:12:04 +03:00
