Theo dõi VM
NOTE The JavaScript-based Tracing of VM Tracing APIs is considered unsafe to be opened to public. If you want to provide VM Tracing APIs to the public, we strongly recommend you to set the rpc.unsafe-debug.disable flag which will disable the Javascript-based Tracing and only allow pre-defined tracers.
debug_traceBadBlock
The traceBadBlock method will return a full stack trace of all invoked opcodes of all transactions that were included in this block.
NOTE: the parent of this block must be present or it will fail.

>Các tùy chọn theo dõi
You may give trace API function a secondary optional argument, which specifies the options for this specific call. The possible options are:
disableStorage:BOOL. Đặt thành true sẽ vô hiệu hóa tính năng thu thập lưu trữ (mặc định = false).disableMemory:BOOL. Đặt thành true sẽ vô hiệu hóa tính năng thu thập bộ nhớ (mặc định = false).disableStack:BOOL. Đặt thành true sẽ vô hiệu hóa tính năng thu thập ngăn xếp (mặc định = false).hết thời gian chờ:CHUỖI. Ghi đè thời gian chờ mặc định là 5 giây cho các lệnh gọi theo dõi dựa trên JavaScript. Các giá trị hợp lệ được mô tả tại đây.trình theo dõi:CHUỖI. Thiết lập cài đặt này sẽ kích hoạt theo dõi giao dịch dựa trên JavaScript, được mô tả trong phần tiếp theo. Nếu được thiết lập, bốn đối số trước đó sẽ bị bỏ qua. Các trình theo dõi được xác định trước cũng có thể được sử dụng như trong bảng sau.

Mô tả
4byteTracer
4byteTracer tìm kiếm các mã định danh 4byte và thu thập chúng để xử lý hậu kỳ. Phương thức này sẽ thu thập các mã định danh phương pháp cùng với kích thước của dữ liệu được cung cấp, do đó, chữ ký đảo ngược có thể khớp với kích thước của dữ liệu.
callTracer
callTracer là một công cụ theo dõi giao dịch toàn diện trích xuất và báo cáo tất cả các lệnh gọi nội bộ được thực hiện bởi một giao dịch cũng như các thông tin hữu ích khác.
fastCallTracer
fastCallTracer là phiên bản Go-native của callTracer. Do nó không được thực thi trên máy ảo JavaScript nên nó sẽ hiển thị tốc độ gấp 10 lần so với callTracer. Hãy sử dụng fastCallTracer thay vì callTracer nếu ưu tiên hiệu suất.
evmdisTracer
evmdisTracer trả về đầy đủ thông tin theo dõi để thực hiện quá trình phân giải kiểu evmdis.
noopTracer
noopTracer là mã soạn sẵn cơ bản được yêu cầu từ một đối tượng JavaScript để sử dụng làm công cụ theo dõi giao dịch.
opcountTracer
opcountTracer là công cụ theo dõi mẫu chỉ đếm số lượng lệnh được KLVM thực thi trước khi giao dịch kết thúc.
prestateTracer
prestateTracer cung cấp thông tin đầy đủ để thực thi cục bộ một giao dịch từ một khối khởi nguyên được kết hợp tùy chỉnh.
revertTracer
revertTracer cung cấp chuỗi lỗi REVERT. Nếu quá trình thực thi không được hoàn nguyên, nó sẽ xuất ra một chuỗi trống.
unigramTracer
unigramTracer trả về số lần xuất hiện của mỗi mã vận hành.
bigramTracer
bigramTracer trả về số lần xuất hiện của hai mã vận hành liên tiếp.
trigramTracer
trigramTracer trả về số lần xuất hiện của ba mã vận hành liên tiếp.

NOTE The JavaScript-based Tracing allows the user to run arbitrary JS code, which is unsafe. If you want to provide debug namespace APIs to the public, we strongly recommend to set the rpc.unsafe-debug.disable flag when running the EN, so the JavaScript-based Tracing can be disabled.
Specifying the tracer option in the second argument enables JavaScript-based tracing. In this mode, tracer is interpreted as a JavaScript expression that is expected to evaluate to an object with (at least) two methods, named step and result.
step is a function that takes two arguments, log and db, and is called for each step of the KLVM, or when an error occurs, as the specified transaction is traced.
log has the following fields:
Tên trường
type
Mô tả
pc
Số
Bộ đếm chương trình hiện tại.
op
Đối tượng
Một đối tượng Mã vận hành đại diện cho mã vận hành hiện tại.
gas
Số
Lượng gas còn lại.
giá gas
Số
Chi phí tính bằng peb của mỗi đơn vị gas.
bộ nhớ
Đối tượng
Một cấu trúc đại diện cho không gian bộ nhớ của hợp đồng.
ngăn xếp
array[big.Int]
Ngăn xếp thực thi KLVM.
độ sâu
Số
Độ sâu thực thi.
tài khoản
Chuỗi
Địa chỉ của tài khoản thực hiện thao tác hiện tại.
lỗi
Chuỗi
Nếu xảy ra lỗi, thông tin về lỗi đó.
If err is non-null, all other fields should be ignored.
For efficiency, the same log object is reused on each execution step, updated with current values; make sure to copy values you want to preserve beyond the current call. For instance, this step function will not work:
function(log) {
this.nhật ký.append(log);
}But this step function will:
function(log) {
this.nhật ký.append({gas: log.gas, pc: log.pc, ...});
}log.op has the following methods: log.op has the following methods:
Tên phương pháp
Mô tả
isPush()
Trả về true nếu mã vận hành là PUSHn.
toString()
Trả về chuỗi đại diện của mã vận hành.
toNumber()
Trả về số của mã vận hành.
log.memory has the following methods: log.memory has the following methods:
Tên phương pháp
Mô tả
slice(start, stop)
Trả về phân đoạn bộ nhớ đã chỉ định dưới dạng lát cắt byte.
length()
Trả về độ dài của bộ nhớ.
log.stack has the following methods:
Tên phương pháp
Mô tả
peek(idx)
Trả về phần tử thứ idx từ đầu ngăn xếp (0 là phần tử trên cùng) dưới dạng big.Int.
length()
Trả về số phần tử trong ngăn xếp.
db has the following methods:
Tên phương pháp
Mô tả
getBalance(address)
Trả về big.Int với số dư của tài khoản được chỉ định.
getNonce(address)
Trả về một số với số dùng một lần của tài khoản được chỉ định.
getCode(address)
Trả về một lát byte có mã cho tài khoản đã chỉ định.
getState(address, hash)
Trả về giá trị trạng thái cho tài khoản được chỉ định và hàm băm được chỉ định.
exists(address)
Trả về true nếu địa chỉ được chỉ định tồn tại.
The second function, result, takes no arguments, and is expected to return a JSON-serializable value to return to the RPC caller.
If the step function throws an exception or executes an illegal operation at any point, it will not be called on any further VM steps, and the error will be returned to the caller.
Note that several values are Golang big.Int objects, not JavaScript numbers or JS bigints. As such, they have the same interface as described in the godocs. Their default serialization to JSON is as a Javascript number; to serialize large numbers accurately call .String() on them. For convenience, big.NewInt(x) is provided, and will convert a uint to a Golang big.Int.
As an usage example below, it returns the top element of the stack at each CALL opcode only:
debug.traceTransaction(txhash, {tracer: '{data: [], step: function(log) { if(log.op.toString() == "CALL") this.data.push(log.stack.peek(0)); }, result: function() { return this.data; }}'});Last updated
