Functions

func NewErrnoSystem 

func NewErrnoSystem(errno Errno) System

NewErrnoSystem creates a wasi.System that returns an errno for all calls.

func NewExitSystem 

func NewExitSystem(exitCode int) System

NewExitSystem creates a wasi.System that exits all calls with the exit code.

func NewFallbackSystem 

func NewFallbackSystem(primary, secondary System) System

NewFallbackSystem creates a wasi.System that wraps two other wasi.System instances, a primary and a secondary. Calls are first forwarded to the primary system, and then forwarded to the secondary system when the primary returns wasi.ENOSYS.

func NewObserver 

func NewObserver(system System, before, after func(context.Context, Syscall)) System

NewObserver creates a wasi.System that notifies callbacks before and/or after a system call.

func NewRecorder 

func NewRecorder(system System, write func(SyscallID, []byte)) System

NewRecorder creates a wasi.System that records system calls.

The provided write function must consume the write immediately as it's reused across function calls.

type Codec 

type Codec struct{}

Codec is responsible for encoding and decoding system call inputs and outputs.

The system calls are sealed so there's no need for forwards or backwards compatibility. Rather than use protobuf or flatbuffers or similar, we use simple bespoke encoders. We aren't too concerned with succinctness since the records are ultimately compressed.

Other things that have been tried:

  • varints (bb159c7, discussed in stealthrocket/timecraft#11)
  • omitting return values except for errno when errno!=ESUCCESS (532bfbb, discussed in stealthrocket/timecraft#11)

type ReadError

type Reader 

type Reader struct {

func NewReader 

func NewReader(records stream.Reader[timemachine.Record]) *Reader

NewReader creates a Reader.

func (*Reader) ReadSyscall 

func (r *Reader) ReadSyscall() (time.Time, Syscall, error)

ReadSyscall reads a recorded system call.

type Replay 

type Replay struct {
	Stdout io.Writer
	Stderr io.Writer
	// contains filtered or unexported fields
}

Replay implements wasi.System by replaying system calls recorded in a log.

During replay, records are pulled from the log and then used to answer system calls. No actual system calls are ever made. The WebAssembly module should thus be identical to the one used to create the log records.

When the replay is complete, the implementation will return ENOSYS for subsequent system calls, and the EOF method will return true.

When an error occurs, the replay will panic and the execution of the WebAssembly module will be halted. The following errors may occur:

  • ReadError: there was an error reading from the log
  • DecodeError: there was an error decoding a write from the log
  • UnexpectedSyscallError: a system call was made that did not match the next write in the log
  • UnexpectedSyscallParamError: a system call was made with input that did not match the next write in the log

The error may also be a compound error, indicating that multiple errors were encountered. In this case, the error will implement interface{ Unwrap() []error }.

func NewReplay 

func NewReplay(records stream.Reader[timemachine.Record]) *Replay

NewReplay creates a Replay.
