* perf(erasure): remove UUID from clone + increase encode inflight budget
Two targeted optimizations for the erasure encoding hot path:
1. Erasure::clone() no longer generates Uuid::new_v4() per clone.
The _id field is unused in the hot path; reusing the original ID
eliminates a CSPRNG call per block encode (100 calls for a 100MB
object with 1MB blocks).
2. Default RUSTFS_ERASURE_ENCODE_MAX_INFLIGHT_BYTES raised from 8MB
to 32MB. This increases the encode pipeline depth from ~5 to ~20
blocks, allowing more read-ahead between the encoder and disk
writer stages. The per-request memory bound is still controlled
by the 8-block hard cap and the env var override.
3. Added encode_data_owned() utility method for zero-copy encoding
when the caller already owns a heap buffer (Vec<u8> → BytesMut
via Bytes::try_into_mut). Not used in the hot path yet but
available for future callers.
All 1157 ecstore tests pass. Criterion micro-benchmarks show no
regression (< 2% variance). Single-machine warp E2E tests were
inconclusive due to high variance; a dedicated multi-disk test
environment is needed for reliable E2E comparison.

* fix(ecstore): remove dead _buf field from Erasure struct
_buf was allocated in new(), clone(), and Default but never read or written.
Each clone() was allocating block_size bytes (typically 10MB) for nothing.
- Remove _buf from struct, Default, Clone, new_with_options
- 51 erasure tests pass
* fix: remove empty line after doc comment

* fix(rio): surface incomplete put bodies
Propagate incomplete PUT request bodies as IncompleteBody instead of allowing erasure encode to treat truncated input as a normal EOF.\n\n- mark premature EOFs in HardLimitReader with an explicit IncompleteBody error\n- preserve EOF error chains through read_full and map them to S3 IncompleteBody\n- stop erasure encode from swallowing UnexpectedEof on truncated input\n- add regression tests for reader, erasure encode, and API error mapping\n\nRefs: rustfs/backlog#654
* fix(s3): honor decoded length for aws chunked put
Use x-amz-decoded-content-length for aws-chunked PutObject requests so trailer-checksum uploads are sized against the decoded payload instead of the wire-encoded content-length.\n\n- prefer decoded content length for aws-chunked put bodies\n- add a regression test covering the size selection logic\n- keeps the incomplete body fix working for truly truncated uploads while restoring checksum trailer compatibility\n\nRefs: rustfs/backlog#654
* fix(io): follow up review comments on incompletebody handling
Address PR review feedback by restoring read_full's existing EOF contract, adding a dedicated read_full_or_eof helper for erasure encoding, covering nested incomplete-body error chains, and documenting plus hardening aws-chunked size selection.\n\n- keep read_full returning early EOF on empty reads\n- use read_full_or_eof only in erasure encoding paths\n- detect aws-chunked via content-encoding or transfer-encoding\n- add nested error-chain and aws-chunked regression tests\n\nRefs: rustfs/backlog#654

* fix(rio): reject bytes beyond hard limit
* fix(ecstore): reject zero-sized erasure blocks
* perf: reduce spawn_blocking contention in PUT path (~23% throughput gain)
Flame graph profiling identified tokio blocking pool mutex contention
as the #1 bottleneck (17.3% of CPU time). Each spawn_blocking call must
acquire parking_lot::raw_mutex to enqueue work. With 16 concurrent PUTs
× 4 disks × 3+ spawn_blocking per disk, this became a serialization point.
Optimizations applied:
- Merge make_dir_all + file write into single spawn_blocking
- Merge read_file + parse + write + rename into single spawn_blocking
for inline objects (small files)
- Optimize reliable_rename to try rename first, mkdir only on ENOENT
- Optimize remove/remove_std to try remove_file first, EISDIR fallback
- Add encode_inline_small fast path for small objects
- Parallelize bitrot writer creation with join_all
Benchmark (4KiB PUT, 4-disk EC, 16 concurrent, 8 rounds, randomized A/B):
Baseline: ~950 obj/s → Optimized: ~1173 obj/s (+23%)

* test: add unit tests for encode_inline_small fast path
* test: fix comment and line length in encode_inline_small tests
* fix: revert reliable_rename and write_all_internal to match original
Restore the original reliable_rename logic (check parent exists, then
rename in loop) and the original write_all_internal (make_dir_all outside
spawn_blocking). The optimization changes caused a CI-only test failure
in capacity_dirty_scope_test that could not be reproduced locally.

Object repair rebuilt missing data shards but left missing parity shards unrecreated. A parity-only repair could therefore complete without restoring the shard contents.
Add a repair-specific reconstruction path that regenerates parity after data shards are available, while keeping normal read decoding data-only. Also shut down repair writers after all blocks are written.
Constraint: Preserve read-path decode behavior and limit parity regeneration to repair.
Confidence: high
Scope-risk: moderate
Directive: Do not route read decoding through parity regeneration without measuring the cost.
