Fileupload Gunner Project New

One standout feature of the fileupload gunner project new architecture is its intelligent chunk reassembly. When a client uploads a file in chunks, Gunner temporarily stores each chunk in Redis with a TTL (time-to-live). Once all chunks are received, a background worker reassembles them in the correct order using a deterministic chunking algorithm.

How to enable:

// Client-side (JavaScript)
const uploader = new GunnerUploader(
  projectId: "my-upload-service",
  chunkSize: 5 * 1024 * 1024,
  parallelChunks: 3
);
uploader.upload(file, 
onProgress: (percent) => console.log($percent%),
onComplete: (etag) => console.log(Upload complete: $etag)
);

The "New" project introduces three major subsystems: One standout feature of the fileupload gunner project

A "fileupload gunner" is a load- and functional-testing tool that repeatedly uploads files to a target endpoint to measure throughput, latency, error behavior, and server-side handling under realistic or adversarial conditions.

For mission-critical files, the new project can simultaneously upload to three object stores (e.g., S3, Backblaze, and local disk). If one mirror fails, the Gunner automatically cuts over without user intervention. The "New" project introduces three major subsystems: A

In a standard web application, fileupload refers to the process of sending binary or text files from a client to a server. However, within the gunner project ecosystem, fileupload takes on additional complexity:

| Test case | Expected behavior | |-----------|------------------| | Upload .exe as .jpg | Reject (magic bytes mismatch) | | Upload file >10MB | Reject (size limit) | | Upload EICAR test string | Reject (malware) | | Upload ../../../config.php | Sanitized to _____config.php | | 200 requests in 1 minute | HTTP 429 rate limit |

Always perform MIME sniffing on the file's first 512 bytes. Gunner projects include a magic_number validator:

// internal/validator/mime.go
func ValidateMime(data []byte) error 
    mime := http.DetectContentType(data)
    if !allowedMimes[mime] 
        return errors.New("invalid content type")
return nil
