perf(rpc): remove stream boxing and verify distributed TLS reads (#8885)
* perf(rpc): remove redundant boxing from read streams Keep the capped read stream concrete until StreamingBlob owns its type erasure. Add verified four-node TLS coverage for full, unaligned range and concurrent reads, with bounded client memory and explicit integrity checks. Document protocol comparison commands and the old-node workaround during rolling upgrades. Co-Authored-By: heihutu <heihutu@gmail.com> Co-Authored-By: zhi22915 <qiuzgang@gmail.com> * test(e2e): preserve TLS trust for alternate credentials Derive credential-specific clients from the cluster configuration so they retain the generated CA. Exercise successful trusted reads and reject an invalid replacement identity instead of inheriting root credentials. Co-Authored-By: heihutu <heihutu@gmail.com> Co-Authored-By: zhi22915 <qiuzgang@gmail.com> * test(e2e): collapse acceptance report path guard Combine the optional report path and existing-file checks into a let chain without changing the report or PID sidecar collision behavior. Co-Authored-By: heihutu <heihutu@gmail.com> Co-Authored-By: zhi22915 <qiuzgang@gmail.com> --------- Co-authored-by: heihutu <heihutu@gmail.com> Co-authored-by: zhi22915 <qiuzgang@gmail.com>

Set the protocol on every node and restart the processes. The node initiating a read, scan, or heal chooses the outbound protocol. With `http1`, retain the normal connection-pool settings; there is no need to set the maximum idle count to zero to isolate active bodies.
|
||||
|
||||
During a rolling upgrade, keep `RUSTFS_INTERNODE_HTTP_POOL_MAX_IDLE_PER_HOST=0` on older nodes that lack the protocol selector. Their coordinators, scanner and heal workers still choose the older outbound policy. After a node runs a release with the selector, use `http1` and restore its normal idle-pool setting. New response framing alone does not isolate streams initiated by an older HTTP/2 client.
|
||||
|
||||
HTTP/2 window and adaptive-window settings apply only with `auto` and a TLS connection that negotiates HTTP/2. The `legacy`, `balanced`, and `throughput` tuning profiles continue to control their existing pool and window settings; none overrides the protocol policy.
|
||||
|
||||
HTTP/1.1 uses more concurrent connections than multiplexed HTTP/2. Size file-descriptor and connection budgets for the workload. For bounded reads, consuming the full advertised byte count completes HTTP framing and permits reuse without an additional EOF poll. Unknown-length reads still require EOF. Cancelled or partially consumed responses can close their connections. A bounded response that ends early is a transport error; the server retains its existing read cap and never pads or shrinks a short response into success. Disabling pooling also adds TCP/TLS setup and connection churn to subsequent requests. No universal throughput improvement is implied by the protocol default.
|
||||
|
||||
For validation, compare complete 100 MiB and 1 GiB GETs through every coordinator, verify lengths and hashes, and include concurrent GET, scanner, and heal activity. Record latency, stall errors, CPU, connection counts, and file descriptors. Include small objects and uploads when assessing a deployment's performance. Local transport tests exercise TLS ALPN, shared HTTP/2 backpressure, full-body delivery, and HTTP/1.1 idle reuse; they do not replace a distributed cluster run.
|
||||
|
||||
The distributed E2E case below starts four processes with four drives each and a generated CA. Both S3 and volume endpoints use verified TLS. It streams 32 KiB, 100 MiB and 1 GiB uploads from files, checks complete and unaligned Range responses through every coordinator, and repeats full reads with all four coordinators active concurrently. Each GET checks Content-Length, Content-Range where applicable, the received byte count and SHA-256. SDK GET retries are disabled, and captured node logs must contain no internode body stalls.

Use an unused report filename for each invocation. The report has per-request timings and integrity results; adjacent files retain node logs and process IDs for external resource sampling. `RUSTFS_E2E_INTERNODE_HTTP_MODE=auto` selects pooled protocol negotiation, and `unpooled` selects the same negotiation with the idle pool disabled. Scanner and heal are enabled, but this case does not inject damage or certify their progress. A passing result does not complete mixed-version, mTLS or certificate-rotation acceptance.
|
||||
|
||||
These correctness timings are not a capacity benchmark: the client hashes every byte and shares a host with the four servers. For performance attribution, use the same release binary, topology and workload in isolated ABBA runs, gather CPU, FD, connections and TIME_WAIT externally, and reject candidate conclusions when the repeated baseline drifts. A few correctness requests cannot establish p99 or universal protocol superiority.
|
||||
|
||||
The mechanism follows [HTTP/2 flow control](https://www.rfc-editor.org/rfc/rfc9113.html#name-flow-control): stream and connection DATA credit both apply. In the client dependency, credit is released when the application polls body frames. Multiple paused bodies can therefore consume shared connection credit required by a stream the caller is still waiting for. Increasing a finite window or retrying the GET does not remove this coupling. Control frames and response headers are not subject to DATA credit.
|
||||
|
||||
S3 [GetObject](https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetObject.html) defines the returned object body, content length, and byte-range semantics; it does not require HTTP/2 for internode transport. This policy changes the transport below the existing integrity, quorum, timeout, and identity-fenced resume behavior.
