示例1: AppendLogChunk

func AppendLogChunk(db database.Database, artifact *model.Artifact, logChunk *model.LogChunk) *HttpError {
	if artifact.State != model.APPENDING {
		return NewHttpError(http.StatusBadRequest, fmt.Sprintf("Unexpected artifact state: %s", artifact.State))
	}

	if logChunk.Size <= 0 {
		return NewHttpError(http.StatusBadRequest, "Invalid chunk size %d", logChunk.Size)
	}

	if logChunk.Content == "" {
		return NewHttpError(http.StatusBadRequest, "Empty content string")
	}

	if int64(len(logChunk.Content)) != logChunk.Size {
		return NewHttpError(http.StatusBadRequest, "Content length does not match indicated size")
	}

	// Find previous chunk in DB - append only
	if nextByteOffset, err := db.GetLastByteSeenForArtifact(artifact.Id); err != nil {
		return NewHttpError(http.StatusInternalServerError, "Error while checking for previous byte range: %s", err)
	} else if nextByteOffset != logChunk.ByteOffset {
		return NewHttpError(http.StatusBadRequest, "Overlapping ranges detected, expected offset: %d, actual offset: %d", nextByteOffset, logChunk.ByteOffset)
	}

	logChunk.ArtifactId = artifact.Id

	// Expand artifact size - redundant after above change.
	if artifact.Size < logChunk.ByteOffset+logChunk.Size {
