* core: vm: sqlvm: add ESCAPE grammarwmin02019-03-264-653/+768
| | | | | Provide ESCAPE grammar for specifying escape character in like pattern matching.
* core: vm: sqlvm: errors: add length fieldTing-Wei Lan2019-03-265-442/+484
| | | | | When an error corresponds to a source code token, it should be able to report the length of the token in addition to the position.
* core: vm: sqlvm: limit the depth of AST to 1024Ting-Wei Lan2019-03-263-7/+50
| | | | | Since we traverse an AST by calling functions recursively, we have to protect the parser by limiting the depth of an AST.
* core: vm: sqlvm: parser: move generated code to internal packageTing-Wei Lan2019-03-265-1565/+1585
| | | | | | | | Code generated by pigeon includes many exported symbols which should not be used by any other code other than the parser itself. To prevent them from being misused, we used to hide them by editing the generated code with sed. This commit removes the unreliable sed trick by putting generated code to internal package.
* core: vm: sqlvm: ast: use non-empty interfaces in DataType{En,De}codeTing-Wei Lan2019-03-262-80/+34
| | | | | | | In addition to changes required to move DataTypeEncode and DataTypeDecode to use TypeNode interface, this commit also unifies the meaning of 'Size' field in 'FixedBytesTypeNode'. It always counts the length in bytes now.
* core: vm: sqlvm: errors: fix typoTing-Wei Lan2019-03-261-1/+1

* core: vm: sqlvm: parser: don't use @, #, $ in unquoted identifiersTing-Wei Lan2019-03-262-35/+34
| | | | | | These symbols are allowed in Microsoft SQL or PostgreSQL, but the SQL standard doesn't mention them. It is still possible to use these symbols as identifiers by putting them in double quotes.
* core: sqlvm: schema: define type for table/column/index/sequence sizeyenlin.lai2019-03-262-5/+17
| | | | | The size of table in db and column/index/sequence in a table is bounded by uint8. Define types for better readability.
* core: vm: sqlvm: ast: handle error in AST printerTing-Wei Lan2019-03-262-33/+63
| | | | Catch the error reported by fmt.Fprintf and report it to the caller.
* core: vm: sqlvm: fill source code position in AST nodesTing-Wei Lan2019-03-267-1141/+1510
| | | | | | | | | | | | | | | Now all AST nodes should have position information recorded during parsing. These fields are intended to be used to report errors and make debugging easier. However, precise location of each token is currently unavailable. It can be done in the future if it becomes necessary. To make it easier to traverse an AST, GetChildren is modified to skip nil nodes in the output. This means callers of GetChildren don't have to check for nil in returned slices. AST printer is modified to print the position and the corresponding source code token. A few special handling for interfaces are removed because reflection works better for structs.
* core: vm: sqlvm: ast: use pointer receiversTing-Wei Lan2019-03-261-89/+89
| | | | | | | Since all nodes must be declared as pointers to satisfy the interface, it is no longer meaningful to use value receivers. It should make the code look more consistent and reduce the amount of memory copying during function calls because these structs takes at least 8 bytes.
* core: vm: sqlvm: ast: remove pointer indicator in printer outputTing-Wei Lan2019-03-261-5/+4
| | | | | | Since our 'Node' interface includes methods which must be implemented with pointer receivers, all AST nodes are now referenced with pointers and the '*' pointer indicator is no longer useful.
* core: vm: sqlvm: check if a number is a valid addressTing-Wei Lan2019-03-265-334/+312
| | | | | | | | | | | | This commit implements isAddress function to allow a number literal to be considered as an address literal. Since Solidity only allows '0x' to be written in lower case, we remove the handling of upper case '0X' to keep the behavior in sync with Solidity. In addition to isAddress implementation, this commit also removes 'String' methods from AST nodes to prevent them from implementing the builtin 'Stringer' interface. Therefore, our AST printer is now able to print struct fields of value nodes instead of only one string.
* core: vm: sqlvm: introduce interfaces for AST nodesTing-Wei Lan2019-03-269-1704/+2956
| | | | | | | | | In order to make our AST easier and safer to use, all declarations with empty interface type are now removed. This changes also makes it possible to traverse the AST without using reflection or understanding what each type means because all AST nodes have at least one common interface.

| | | | | Modify Tuple.Data.Value type from *big.Int to interface{} and remove Max, Min.
* core: vm: sqlvm: shared interfaces and paramsJhih-Ming Huang2019-03-266-0/+245
| | | | | | | After reconstructing commits, we move shared interfaces and params as first runtime implementation. In this commit we define OP codes, runtime flow and entrypoint, and basic operand structs and minor helper components.

* core: vm: sqlvm: ast: don't hardcode output and indent in PrintASTTing-Wei Lan2019-03-262-26/+35
| | | | | It is now possible to write AST dump to a writer other than stdout and use indent string other than 2 spaces.
* core: vm: sqlvm: process non-UTF-8 input and escape sequencesTing-Wei Lan2019-03-268-337/+579
| | | | | | | | | | | | | | | Our parser is able to process queries with invalid UTF-8, provided that it is compatible with ASCII. Since doing so requires encoding the input before passing to pigeon, Parse* functions generated by pigeon are unexported because they should not be used directly. Escape sequences in string literals and identifiers are now recognized. In addition to escape sequences supported by solidity, we support \U similar to the one supported by Go to allow users to specify non-BMP Unicode code point without using multiple \x escapes. AST printer is modified to quote non-printable characters in strings to prevent control characters from messing up the terminal.
* core: vm: sqlvm: parser: properly handle errorsTing-Wei Lan2019-03-266-1242/+1637
| | | | | | Instead of ignoring errors, errors returned from external functions are normalized and reported to users. Errors which should be impossible to occur are converted to panic calls.
* core: vm: sqlvm: remove optional interface and add print tag for detailwmin02019-03-263-99/+49
| | | | | | | There are some changes in print ast utility. 1. instead of using optional interface to get detail, use reflect 2. implement a `print` field tag for printer switching detail mode or not
* core: vm: sqlvm: move AST and parser to their own packagesTing-Wei Lan2019-03-268-1837/+2010
| | | | | | | | In order to avoid putting too many different things in single package and allow other projects to reuse the syntax tree and the parser, these two components are moved to different packages and all nodes used in AST are now exported. A lot of comments are added in this commit to pass golint checks.
* core: vm: sqlvm: add a tool to run gofmt on pigeon sourcesTing-Wei Lan2019-03-261-0/+253
| | | | | | This tool is good enough to format our sqlvm grammar file. It is not guaranteed to work for all valid pigeon files, and it only process multi-line Go code blocks.
* core: vm: sqlvm: add sql language parser prototypingwmin02019-03-2613-0/+11043

* dex: reduce msg when broadcast tx (#292)Sonic2019-03-212-19/+51
| | | | | | | | | | Our network topology is different from ethereum, the nodes in notary set will connect each other directly. So there is a waste for flooding tx msgs in notary set. And nodes in notary set are more likely to propose block successfully, it is not useful to broadcast tx msgs to non notary set nodes. This PR will increase some tx confirm latency, but can reduce waste tx msgs a lot.

| | | | | | | | | | Since a qualified node might fail stopped, we need to remove them from qualified nodes to maintain network integrity. We do this by inspect the previous round to see if there are dead nodes. A dead node is a notary set node that does not propose any block in the previous round. We disqualify them by fining them so their staked value is 1 wei below minStake. This make them unqualified for being notary set in the follow on rounds.

* dex: align recovery dMoment when resuming consensus (#271)Wei-Ning Huang2019-03-181-1/+16
| | | | | | In theory BA should tolerant inconsistant start time between every node. Since the vote cache is limited, we can not keep all the votes and pass them around all nodes. To fix this, we align the next recovery dmoment so nodes start at the same time.

| | | | | | | | | | The refactor in 4cd90e02e23ecf2bb11bcb4bba4fea2ae164ef74 introduced livness checks for nodes. However, the change in 86ec742f975d825f42dd69ebf17b0adaa66542c0 did not properly set the initial liveness check value for verified node. For verified node we should set livenessCheck to 1 initially. Without this change, the node entry will not be properly send to other nodes and the network would be broken.

* core: vm: remove delegation mechanism (#245)Wei-Ning Huang2019-03-128-1001/+267
| | | | | | | | | | | | | The current delegation mechanism are prone to unstaking attack. i.e. a malicious attacker could unstake a small amount from a lot of node it staked before and make them unqualified, which leads to potential failure of the network. Since DEXON does not use consensus like DPoS, node is required to have at least MinStake in order to become a node. Voting mechanism is not required in our system since qualified node does not depends on the number of votes. Instead of managing the delegation mechanism in governance contract, we should let the owner manage the delegation and reward distribution mechanism on their own.

* core: vm: modify randomness calculation algorithm (#173)Wei-Ning Huang2019-03-122-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | The original algorithm used for calculating algorithm is vulnerable to cross context re-entry attack. Example as follows: contract B { event Value(uint256 value); uint256 public value; function call() public { value = rand; emit Value(value); } } contract A { function randTwice(address bAddr) public { B b = B(bAddr); b.call.gas(100000)(); b.call.gas(100000)(); } } The two `b.call` will result in the same randomness value. This commit fix the issue by recording a called index used to store how many times opRand is called, and use it as argument to the Keccak call.

| | | | | | | | | | Using only state root and receipt root as witness data can not protect other fields in block header, ex: bloom, difficulty, gas limit, gas used... So that everyone can manipulate these fields to create as many valid blocks at the same height as he want. Although this will not effect the state, one can spam us when syncing. Using block hash as witness data can solve this.

This commit also fix when a block confirm but its parent is not in db yet, during restarting proposing. * dex: always accept NewBlockMsg, NewBlockHashesMsg We need to accept NewBlockMsg, NewBlockHashesMsg to sync current block with other peers in block proposer mode when syncing lattice data. It's a waste when the node is synced and start proposing. Todo: control msg processing on/off more granular, accept NewBlockMsg, NewBlockHashesMsg when syncing, but stop when synced.

| | | | | | | | | | | | | | | - Broadcasting blocks at chain head event is not correct when the full node is not running in block proposer mode. Introduce NewFinalizedBlockEvent, this event is post by the full node which runs in block proposer mode when a block is witnessed and resulting in some blocks are considered finalized. - Non block proposer node will still broadcast blocks at the following moment (same as ethereum): 1. a sync with a peer is terminated successfully 2. a block passes the fetcher's header check during inserting blocks 3. a block is successfully inserted by fetcher - Don't trigger a sync when we are not behind other peers more than acceptable distance.
