Add `tee_reader` / `tee_reader_with_options` in `rustfs-rio`: a
`TeePrimary` that drives the source and a `TeeSecondary` that observes
an identical copy of every chunk through a byte-bounded queue. The
primary returns `Pending` when the queue is full, so both sides advance
at the pace of the slowest consumer; it is meant for small objects only.
Termination: source EOF and errors propagate to the secondary with the
same `io::ErrorKind`; dropping the secondary turns the primary into a
pass-through; dropping the primary early fails the secondary with
`BrokenPipe` by default, or hands the remaining source to a background
drain task bounded by `max_drain_bytes` when
`TeeOptions::drain_on_primary_drop` is set. `TeeSecondary::into_stream`
exposes the queued `Bytes` chunks without an extra copy.
Includes a proptest equivalence test, backpressure, error, drop,
drain-limit and cancel-safety tests, and a criterion bench comparing
tee throughput against a direct read (64 MiB in 1 MiB chunks).
Merge the hotpath-rs wall-time instrumentation from the backlog#936 analysis worktree behind an opt-in 'hotpath' cargo feature, keeping the default build at zero overhead and zero dependency.
- hotpath is an optional dependency everywhere (dep:hotpath feature syntax); the default dependency tree contains no hotpath crate at all
- 40+ measurement points across S3 handlers, ECStore/SetDisks object and multipart ops, erasure encode/decode, bitrot, LocalDisk I/O, FileMeta codec, and HashReader
- attribute sites use #[cfg_attr(feature = "hotpath", hotpath::measure)]; async_trait bodies use per-crate hp_guard! macros (ecstore + rustfs bin); rio gates measure_block! behind hp_measure_block!
- feature chain: rustfs -> rustfs-ecstore -> rustfs-rio / rustfs-filemeta, each crate owning its own gate
- hotpath-alloc is intentionally not wired up (hotpath 0.21.x TLS panic on cross-thread guard drop under tokio, see backlog#935); mimalloc stays the unconditional global allocator
- docs/development/hotpath-profiling.md documents building, HOTPATH_* env vars, SIGTERM report flow, and how to reproduce the backlog#936 timing reports
