Punk-0.24

Changes for version 0.24 - 2026-08-20

  • Large uploads no longer cost what they weigh. A multipart part over 64KB is written to a temp file as it arrives rather than copied into memory, and Punk::Upload carries a `path` and an `fh` to it. Measured end to end through a socket into a handler holding the upload, a 128MB upload costs a worker 15.5MB of RSS against roughly 275MB before.
  • ADDS: the `upload_dir` keyword, naming where a large part is spilled. It decides the filesystem, which decides whether save() is a rename, and it decides what shares a filesystem with attacker controlled bytes. Temp file names owe nothing to the client's filename, and every file is removed when its request ends.
  • ADDS: Punk::Plugin::Blob stores an on-disk upload without reading it into memory: hashed where it lies through Apophis's identify_fh, then moved into the store.
  • ADDS: Punk::Plugin::Idempotency - Idempotency-Key on unsafe methods, replaying the stored response.
  • ADDS: Punk::Plugin::Metrics - a Prometheus /metrics endpoint
  • ADDS: Punk::Plugin::Health - /healthz and /readyz,
  • ADDS: Punk::Plugin::CSP - Content-Security-Policy with a per request nonce.
  • ADDS: Punk::Plugin::ConditionalGet - ETags and 304s for dynamic responses.
  • ADDS: Punk::Plugin::Blob, content addressed uploads on Apophis. $c->blob_put stores by contents, so a user's filename never becomes a filesystem path. $c->blob_send serves through send_file as a download.
  • ADDS: Apophis to the prerequisites.
