[dependabot]

Bumps github.com/gofiber/fiber/v3 from 3.3.0 to 3.4.0.

Release notes

Sourced from github.com/gofiber/fiber/v3's releases.

v3.4.0

🚀 New

• Complete HTTP QUERY method support (#4436, #4456) Adds the HTTP QUERY method (RFC 10008): fiber.MethodQuery, app.Query() routing, safe/idempotent handling in csrf, idempotency, earlydata and cache, plus client.Query() shorthands.

  app.Query("/search", func(c fiber.Ctx) error {
      return c.Send(c.Body()) // QUERY carries the query expression in the body
  })

  https://docs.gofiber.io/client/rest#query
• Add WithContext variants for session storage I/O (#4393) SaveWithContext, DestroyWithContext, RegenerateWithContext and ResetWithContext propagate deadlines/cancellation to the session storage backend; the plain methods keep working unchanged.

  sess := session.FromContext(c)
  err := sess.SaveWithContext(ctx) // storage write bounded by ctx

  https://docs.gofiber.io/middleware/session#session-with-context-timeoutscancellation
• Unify internal and custom constraints into a single interface (#4397) Built-in and custom route constraints now share one ConstraintHandler interface; the optional ConstraintAnalyzer precomputes constraint data at route registration, removing per-request parsing. Existing CustomConstraint implementations keep working unchanged.

  app.RegisterCustomConstraint(evenConstraint{}) // implements Name() + Execute()
  app.Get("/items/:id<even>", handler)

  https://docs.gofiber.io/guide/routing#constrainthandler-interface
• Expose prefork RecoverInterval and ShutdownGracePeriod (#4491) New ListenConfig knobs: PreforkRecoverInterval delays respawning a crashed child (default 0) and PreforkShutdownGracePeriod sets how long the master waits after SIGTERM before SIGKILL (default 5s).

  app.Listen(":3000", fiber.ListenConfig{
      EnablePrefork:              true,
      PreforkRecoverInterval:     time.Second,
      PreforkShutdownGracePeriod: 10 * time.Second,
  })
