Types

type ABICache 

type ABICache struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

type ABIDecoder 

type ABIDecoder struct {
	// contains filtered or unexported fields
}

ABIDecoder holds the ABI cache, controls it and process transaction on the fly parallel decoding the various elements that needs ABI decoding in-place in the data structure.

The ABI decoder is the one that controls the locking of the cache, so all locking of the cache should be performed by the decoder. The idea here is to have full control of the locking, so we can write-lock the cache and add multiple ABIs inside a single locking session, than resume with the read. That is to improve lock-contention.

type BlockReader 

type BlockReader struct {
	// contains filtered or unexported fields
}

BlockReader reads the dbin format where each element is assumed to be a `bstream.Block`.

func NewBlockReader 

func NewBlockReader(reader io.Reader) (out *BlockReader, err error)

func (*BlockReader) Read 

func (l *BlockReader) Read() (*bstream.Block, error)

type BlockWriter 

type BlockWriter struct {
	// contains filtered or unexported fields
}

BlockWriter reads the dbin format where each element is assumed to be a `bstream.Block`.

func NewBlockWriter 

func NewBlockWriter(writer io.Writer) (*BlockWriter, error)

func (*BlockWriter) Write 

func (w *BlockWriter) Write(block *bstream.Block) error

type ConsoleReader 

type ConsoleReader struct {
	// contains filtered or unexported fields
}

ConsoleReader is what reads the `nodeos` output directly. It builds up some LogEntry objects. See `LogReader to read those entries .

func NewConsoleReader 

func NewConsoleReader(reader io.Reader, opts ...ConsoleReaderOption) (*ConsoleReader, error)

TODO: At some point, the interface of a ConsoleReader should be re-done. 

Indeed, the `ConsoleReader` could simply receive each line already split
since the upstream caller is already doing this job it self. This way, we
would have a single split job instead of two. Only the upstream would split
the line and the console reader would simply process each line, one at a time.

func (*ConsoleReader) Close 

func (l *ConsoleReader) Close()

func (*ConsoleReader) Done 

func (l *ConsoleReader) Done() <-chan interface{}

func (*ConsoleReader) Read 

func (l *ConsoleReader) Read() (out interface{}, err error)

type ConsoleReaderOption 

type ConsoleReaderOption interface {
	// contains filtered or unexported methods
}

func LimitConsoleLength 

func LimitConsoleLength(maxByteCount int) ConsoleReaderOption

LimitConsoleLength ensure that `Console` field on `pbcodec.ActionTrace` are never bigger than `maxByteCount` bytes.

This is sadly incomplete as failing deferred transaction can still log out of band via the standard nodeos logging mecanism.

type CreationFlatNode 

type CreationFlatNode = [3]int

CreationFlatNode represents a flat node in a flat tree. It's a triplet slice where elements reprensents the following values, assuming `(<depthFirstWalkIndex>, <parentDepthFirstWalkIndex>, <executionActionIndex>)`:

The first value of the node is it's id, derived by doing a depth-first walk of the creation tree and incrementing an index at each node visited.

The second value is the parent index of the current node, the index is the index of the initial element of the `CreationFlatNode` slice.

The third value is the execution action index to get the actual execution traces from the actual execution tree (deep-first walking index in the execution tree).

type CreationFlatTree 

type CreationFlatTree = []CreationFlatNode

CreationFlatTree represents the creation order tree in a flatten manners. The flat list is built by doing a deep-first walk of the creational tree, outputting at each traversal the `CreationNode` triplet `(index, creatorParentIndex, executionIndex)` where a parent of `-1` represents a root node.

For example, assuming a `CreationFlatTree` of the form:

[ 

[0, -1, 0],
[1, 0, 1],
[2, 0, 2],
[3, 2, 3],

]

Represents the following creational tree:

``` 

0
├── 1
└── 2
    └── 3

```

The tree can be reconstructed using the following quick Python.

type PermOp 

type PermOp struct {
	Operation   string            `json:"op"`
	ActionIndex int               `json:"action_idx"`
	OldPerm     *permissionObject `json:"old,omitempty"`
	NewPerm     *permissionObject `json:"new,omitempty"`
}

type Specification 

type Specification struct {
	Name  string `json:"name"`
	Value string `json:"value"`
}

type SubjectiveRestrictions 

type SubjectiveRestrictions struct {
	Enable                        bool         `json:"enable"`
	PreactivationRequired         bool         `json:"preactivation_required"`
	EarliestAllowedActivationTime eos.JSONTime `json:"earliest_allowed_activation_time"`
}
