Bumps the turnloop family 0.1.0-alpha.6 → 0.1.0-alpha.7. All 7 direct pins move
in one commit — the crates require each other at ^0.1.0-alpha.N and Perry pins
with =, so mixing versions fails resolution. cargo update moved exactly 9
crates (the 7 plus transitive turnloop-wasi-random, turnloop-zstd-decoder);
all 7 checksums verified against the crates.io API.

Owner-approved publish-age override, applied as
CARGO_RESOLVER_INCOMPATIBLE_PUBLISH_AGE=allow on the re-resolve — cargo has no
per-package exclusion list, so that matches the precedent alpha.6's own comment
records.

Two findings that were not compile errors

ring — would have broken SCRAM-PLUS silently. In alpha.6 ring was an
UNCONDITIONAL dependency of turnloop-tls, so Perry's default-features = false
(present only to exclude the turnloop feature) still yielded ring. alpha.7
makes it optional-but-default, so that same flag newly STRIPS it.

Two consequences, neither a build failure. tls_server_end_point is
#[cfg(feature = "ring")], and it is what perry-tls-session feeds
turnloop-postgres as RFC 5929 channel binding — its own doc notes that a wrong
digest makes the driver offer PLUS and then fail the server signature. And
without ring, default_provider() degrades to a RUNTIME "no rustls crypto
provider" failure.

tls_server_end_point_hash is NOT a drop-in replacement: it returns which
hash RFC 5929 selects (EndPointHash), not the computed Digest. So this adds
features = ["ring"], restoring exactly what alpha.6 gave Perry rather than
opting into anything new. All six consumers use turnloop-tls.workspace = true,
so one edit covers them.

http1 Event::Upgrade — a live silent regression. In request mode alpha.7
raises Event::Upgrade INSTEAD of Event::End (CONNECT, or HTTP/1.1
Upgrade + Connection: upgrade). turnloop_serve/conn.rs already carried an
Event::Upgrade arm written as unreachable — "kept so a later decoder that does
raise it cannot fall through". alpha.7 is that decoder, so the arm went live,
and it was not a compile error.

Left alone it would have bypassed the attached-WebSocketServer precedence and
has_upgrade_listener (#4973: no listener ⇒ serve as an ordinary request), and
stopped dispatching CONNECT as a request. Upgrade now shares the End arm.

Note Event::Upgrade already existed in alpha.6 — what changed is that request
mode now raises it. That is why nothing failed to build.

Where the upstream change-map did not match this workspace

Checked rather than assumed:

  • turnloop-postgres and turnloop-mysql are not dependencies of this workspace
    at all
    , so Error::Transport, Value::Unknown, consume_output,
    Event::Eof and TIME-as-String reach nothing here.
  • PoolConfig (blocking pool) and Backend are unused.
  • DecodeStep is never constructed or destructured — Perry uses
    compression::decode / StreamingDecoder and reads only consumed /
    written, ignoring needs_input, so its loop is robust to process doing
    more per call.
  • LocalExecutor::turn does not reach Perry. That is turnloop-io's
    executor, which Perry deliberately never uses (documented in four places);
    Perry drives Driver::turn(timeout, &mut Completions), byte-identical between
    alpha.6 and alpha.7 apart from an internal self.budget() argument. There is
    no completion leak.

Flagged, deliberately not done

alpha.7 carries the peer's SettingsFrame and GOAWAY debug data, both of which
Perry's h2 pre-scan works around. Five module/doc comments asserting the old API
as current fact are corrected here; the pre-scan itself is untouched, since
moving three node:http2 surfaces wants its own commit and an h2spec run.
Loop::rebuild may suit the drop-and-recreate at
event_pump/agent_loop.rs:559 — not changed.

Verification

  • cargo check --workspace --all-targets (UI excludes): exit 0, 0 errors, 0 warnings
  • RUST_TEST_THREADS=1 cargo test --release -p perry-runtime: 4377 passed, 0 failed
  • cargo test for perry-db-turnloop and the five other edited crates: 260 passed, 0 failed
  • cargo fmt --check clean; check_file_size.sh, binding_pins.mjs --check
    ("17 pinned, lock-step holds"), binding_governance.py, tokio_inventory.py,
    workspace_architecture.py, addr_class_inventory.py,
    gc_runtime_root_holders.py, check_node_version_consistency.py,
    npm run soak: all pass

Pre-existing, each reproduced on the base tree rather than assumed:
scripts/run_lint_gates.sh cannot run at all (exits 4 on the cargo-xwin
extraction error — fixed separately in #11081), and perry-stdlib's full suite
SIGABRTs in readline::mod_tests::listeners_provider_roots_readable_snapshot_…
which passes in isolation and fails only in the full suite, i.e. order-dependent
global state unrelated to turnloop.

📝 Walkthrough

Walkthrough

The workspace Turnloop dependencies move from alpha.6 to alpha.8. Perry’s HTTP integration updates event handling and request routing. TLS and TCP options now specify provider and default values. SMTP event handling and MongoDB comments also change.

Changes

Turnloop alpha.8 upgrade

Layer / File(s) Summary
Dependency versions and upgrade notes
Cargo.toml, changelog.d/11083-turnloop-alpha8.md
The workspace Turnloop dependencies move to alpha.8. The TLS dependency explicitly enables ring, and the changelog records release details and integration changes.
HTTP event handling and request routing
crates/perry-ext-http/src/server/turnloop_h2/*, crates/perry-ext-http/src/server/turnloop_serve/conn.rs
The HTTP/2 adapter handles the updated SETTINGS and GOAWAY event shapes while retaining the pre-scan as the source of existing settings and GOAWAY data. The HTTP/1 router sends Event::Upgrade through the same routing as Event::End, including WebSocket precedence, upgrade-listener dispatch, or ordinary request dispatch.
TLS provider and TCP option defaults
crates/perry-ext-ws/src/turnloop_io.rs, crates/perry-http-client/src/{tls.rs,transport.rs}, crates/perry-runtime/src/turnloop_net/mod.rs, crates/perry-stdlib/src/turnloop_tls_client.rs, crates/perry-tls-turnloop/src/lib.rs
TLS client options explicitly select the Turnloop default provider. TCP option construction retains nodelay and fills other fields from TcpOpts::default().
SMTP and MongoDB compatibility updates
crates/perry-stdlib/src/turnloop_smtp/mod.rs, crates/perry-ext-mongodb/src/turnloop_io/ops.rs
The SMTP event match adds an empty BodyReady arm for its whole-message send path. The MongoDB change updates comments and does not change code behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Pulled this back out of train 260. It is not wrong — it is expensive, in a way worth writing down.

benchmarks/public_baseline.py fingerprints Cargo.toml as a SOURCE_PATHS input, and _fingerprint_bytes hashes the whole file, normalizing only the workspace version (_normalize_cargo_workspace_version). #7282 narrowed HARNESS_PATHS, not this. So the alpha.6 → alpha.8 bump — dependency lines and the long comment block above them — changes the source fingerprint and hard-fails the required lint step:

public baseline error: public artifact benchmark inputs changed; regenerate it with ./benchmarks/run_public_baseline.sh

I measured it rather than guessed. With this commit in the train: source fingerprint adee565142…. With just this commit dropped: 9c87723d7c…, byte-identical to main, and python3 benchmarks/ci_public_baseline_check.py prints public baseline freshness OK. Nothing else in the train moves it — #11020 also edits root Cargo.toml but nets out to main's exact bytes there.

So landing this requires regenerating the published artifact: ./benchmarks/run_public_baseline.sh, roughly two hours on a quiet machine, pinned to Node v22.23.1 and Bun 1.3.14 per benchmarks/public-baseline-config.json. The pin and the measurement are atomic by design.

Two ways forward, and I would like your view since you own the turnloop line:

  1. Land it together with the regeneration in one PR, which is the honest option and what the gate is asking for.
  2. Batch it with the next Cargo.toml-touching change so one regeneration pays for both.

Either way it should not ride a general merge train, because a train that needs a 2 h measurement stops being a train. Everything else about the bump looks fine — your comment block already does the work of justifying the explicit ring feature and the Detached::from_listener_fd delta.

Update — you are not alone in this. I checked all five open cargo dependency bumps against the public-baseline fingerprint and exactly three trip it: this one, #11062 (base64 0.22 → 0.23) and #11063 (env_logger 0.10 → 0.11). #11064, #11065 and #11067 do not, because their manifest edits are in crate-level Cargo.tomls and Cargo.lock, neither of which is in SOURCE_PATHS — those three are going into the next train.

So the efficient path is one regeneration covering all three of us rather than three separate two-hour runs. I'll assemble that as a dedicated PR carrying #11062 + #11063 + this bump plus the regenerated artifact.

Second blocker, independent of the benchmark artifact, and it is the one that actually sets the timeline.

cargo metadata refuses to resolve this bump:

error: failed to select a version for the requirement `turnloop = "^0.1.0-alpha.8"`
  version 0.1.0-alpha.8 is too new (published 3 hours ago, minimum age 7 days)
  required by package `perry-http-client`

So the workspace's min-publish-age policy holds this until roughly 2026-09-30, whatever happens with the public baseline. Your own Cargo.toml comment block records that alpha.6 came in under an owner-approved one-time publish-age override, so the mechanism exists — but that is the owner's call, not mine, and I am not going to exercise it on a routine bump.

Practical consequence for the batching plan I described earlier: I have dropped this from the baseline-regeneration batch. Coupling it would have meant either holding the regenerated artifact for a week or burning a second two-hour measurement when it finally lands. #11062 and #11063 are independent of the publish-age gate.

When the age clears (or if the owner grants an override), ping me and I will fold it into whichever regeneration is next. Nothing else about the bump looks wrong — the ring feature reasoning and the Detached::from_listener_fd delta in your comment block are exactly the detail that makes it reviewable.

All 7 direct pins move in one commit -- the crates require each other at
`^0.1.0-alpha.N` and Perry pins with `=`, so mixing versions fails resolution.
The re-resolve moved exactly 9 crates (the 7 plus transitive
turnloop-wasi-random and turnloop-zstd-decoder) and nothing else; lockstep is
asserted over the whole lockfile, not eyeballed.

Owner-approved publish-age override, applied as
CARGO_RESOLVER_INCOMPATIBLE_PUBLISH_AGE=allow on the re-resolve, since cargo has
no per-package exclusion list. RELEASING.md wants the release source commit:
d72fea0b4644af0b13376bf62b3b8181206d359e (turnloop release PR #109).

alpha.7 -> alpha.8 is purely additive: it adds `Detached::from_listener_fd`
(turnloop#108) and semver-checks rated it API-compatible. All of the work below
is from alpha.6 -> alpha.7.

TWO CHANGES THAT WERE NOT COMPILE ERRORS

`ring` -- would have broken SCRAM-PLUS silently. In alpha.6 `ring` was an
UNCONDITIONAL dependency of turnloop-tls, so Perry's `default-features = false`
(present only to exclude the `turnloop` feature) still yielded ring. alpha.7
makes it optional-but-default, so the same flag newly STRIPS it.
`tls_server_end_point` is `#[cfg(feature = "ring")]` and is what
perry-tls-session feeds turnloop-postgres as RFC 5929 channel binding -- a wrong
digest makes the driver offer PLUS and then fail the server signature -- and
without ring `default_provider()` degrades to a RUNTIME "no rustls crypto
provider" failure. `tls_server_end_point_hash` is NOT a drop-in: it returns
WHICH hash RFC 5929 selects (`EndPointHash`), not the computed `Digest`
(confirmed with the turnloop maintainer, who has corrected the release notes).
So this adds `features = ["ring"]`, restoring exactly what alpha.6 gave Perry.

http1 `Event::Upgrade` -- a live silent regression. In request mode alpha.7
raises `Event::Upgrade` INSTEAD of `Event::End` (CONNECT, or HTTP/1.1
Upgrade + `Connection: upgrade`). `turnloop_serve/conn.rs` already carried an
`Event::Upgrade` arm written as unreachable, "kept so a later decoder that does
raise it cannot fall through". alpha.7 is that decoder, so the arm went live and
it did not fail to build. Left alone it would have bypassed the attached
WebSocketServer precedence and `has_upgrade_listener` (#4973: no listener =>
serve as an ordinary request), and stopped dispatching CONNECT as a request.
`Upgrade` now shares the `End` arm.

WHERE THE UPSTREAM CHANGE-MAP DID NOT MATCH THIS WORKSPACE, checked not assumed:
turnloop-postgres and turnloop-mysql are not dependencies here at all, so their
listed changes reach nothing; `PoolConfig` and `Backend` are unused; `DecodeStep`
is never constructed or destructured; and `LocalExecutor::turn` does not reach
Perry -- that is turnloop-io's executor, which Perry deliberately never uses and
which does not appear in the lockfile, so there is no completion leak.

Flagged, deliberately not done: Perry's h2 pre-scan works around the peer's
SettingsFrame and GOAWAY debug data now carried by alpha.7 -- five module/doc
comments asserting the old API as current fact are corrected, the pre-scan is
not, since moving three node:http2 surfaces wants its own commit and an h2spec
run. `Loop::rebuild` may suit the drop-and-recreate at event_pump/agent_loop.rs.

Merge queue: rebased onto current main. Conflicts were version/lock only: kept main's version (no bump in the PR — the next train carries it), took the turnloop alpha.8 manifest block as written, and re-resolved Cargo.lock from main's lock with the recorded one-time publish-age override. Only the 9 turnloop-family packages moved (alpha.6 → alpha.8), and every checksum matches this PR's original lock. cargo check --all-targets clean for all 15 turnloop-using crates. Will merge directly once pr-gate is green.
