Why

Perry main now carries the four fixes this repository's in_process story was waiting on — landed as 2779c85c7 (batch #8892, #8893, #8894 → perry#8898) and d2b03a451 (#8924):

Perry PR Perry issue effect on Coop
#8893 perry#8546 class registries are per application image — every in_process app dispatches into its own code; before, only the last-initialised image worked
#8892 perry#8882 the Next fixture loads again (late-bound new for un-hoisted classes; unresolved constructors throw by name)
#8894 perry#8883 TailCallElim's alloca walk is bounded — the fixture compile drops from 92–116 min to ~10 min
#8924 derived-constructor capture stash follows super() in every statement shape (the regression #8892 had been masking)

perry-main.lock: 41e8479a5504013308 (2026-08-28). Version string unchanged at 0.5.1519 — the commit is the freshness signal. rust-toolchain.toml (nightly-2026-08-20) still matches Perry's; rusqlite stays 0.39.

Verification — macOS (M1, host loaded by other builds)

Providers rebuilt from 504013308, daemon/worker rebuilt, fixture compiled through the daemon in 570 s (COOP_NEXT_MAX_RSS_MB=16384), then with #18's harness (COOP_BENCH_REQUEST_PATH=/api/benchmark COOP_BENCH_EXPECT_BODY=checksum COOP_BENCH_EXECUTION_MODE=in_process):

run result
1 app 200
3 apps, preload_concurrency=1 200 / 200 / 200
3 apps, preload_concurrency=4 200 / 200 / 200
2 apps, PERRY_GC_SCHEDULE_SEED=12345 PERRY_GC_SCHEDULE_RATE=0.5 PERRY_GC_PROTECT_FROMSPACE=1 200 / 200, no fault

For contrast, the same table on 0.5.1516 + #14/#15 read ✗/✗/✓ (only the last-initialised app served) — see perry#8546.

Two script changes the Linux box forced

  1. build-perry-libraries.sh builds the ext wrappers. A deployment that imports http, net, events, zlib, … links libperry_ext_<name>.a into its image. The daemon compiles with --no-auto-optimize and a scrubbed environment through Coop's cc shim, so the compiler's on-demand wrapper build cannot succeed there (the shim rejects cargo's proc-macro links: "expected exactly one Perry wrapper ending in __coopHttpEntry, found 0"), and a wrapper built in a separate cargo invocation carries a different tokio compilation than the stdlib archive — a pair the link refuses. They are now built in ONE cargo invocation with perry-runtime-static/perry-stdlib-static and the stdlib pump features, into <perry>/target/release/ — the one directory the daemon's compiler searches without an environment. Set: COOP_PERRY_EXT_WRAPPERS (default http net events lru-cache zlib streams fetch ws uuid), COOP_PERRY_EXT_PUMPS.
    On developer machines this was invisible because a stale ~/.local/lib/libperry_ext_*.a from an old perry install silently satisfied the lookup. With this step in place the compiler's search order (<perry>/target/release/ via the exe-relative candidates comes before any Homebrew or ~/.local/lib fallback) picks the in-tree set; re-running the fixture on the Mac against it: compile 1201 s (cold cache under a new compiler identity, host shared with another build), then 1 app 200; 3 apps serial 200/200/200; 3 apps concurrent 200/200/200 — the same table as above, now without the stale archive in the link.
  2. prepare-next-benchmark.sh compile RSS cap 6 → 12 GB. With TRE bounded the emit phase peaks at ~6.3 GB (macOS and Linux alike); the old cap killed every run. GitHub's 7.75 GB runners never compile this fixture (the proof gates it behind next_fixture).

Plus the harness comment that still described the one-heap limitation.

Verification — Linux (fresh Ubuntu 24.04 box, no prior Perry)

On a fresh Ubuntu 24.04 host (16 cores, 61 GB; nothing pre-installed; Perry 504013308 built from source; the wrappers from change 1 present in .perry-main/target/release/) the daemon's compile reaches the final link in ~5 minutes and then **fails in GNU ld with 2,188 multiple definition of \.str.N' errors** between units of different modules (app-page.runtime.prod.jsroute.js: 1,607; jsonwebtoken/index.jsroute.js: 581). Perry's unit-split path promotes string constants to strong GLOBAL DEFAULTsymbols on ELF, while on Mach-O the same constants come outweak external automatically hidden and ld64 dedups them — which is the only reason the macOS table above links at all. That is a Perry codegen defect (.str.N` numbering restarts per module; the promoted owner definitions collide across modules); a fix PR against Perry is in progress and will be linked here. Until it lands, the Next fixture cannot be linked on Linux — the tiny fixture the Linux proof uses is single-unit and unaffected.

The Linux three-app table will be added once that fix is pinned.

Not covered

  • The Linux proof builds providers with the new ext-wrapper step on a 7.75 GB runner; this PR's CI is the first time that runs there.
  • An un-hoisted-class / split-unit quirk seen on both platforms (string constants emitted with global binding in the four widest units) is being reported to Perry separately; it only bites when the same unit is linked twice.

Summary by CodeRabbit

  • Build Improvements

    • Improved library builds by generating required module libraries directly from the current source tree.
    • Added validation to detect missing libraries early and avoid using outdated locally installed versions.
  • Performance Testing

    • Increased the default memory allowance for benchmark compilation to support larger builds.
  • Documentation

    • Updated benchmark documentation to reflect that in-process execution supports multiple JavaScript heaps.

… #8924), build ext wrappers coherently

perry-main.lock: 41e8479a5 -> 504013308 (2026-08-28). The version string is
unchanged at 0.5.1519; the commit is what moved. In the range:

- #8893 (perry#8546): class registries become per application image. Every
  in_process application now dispatches into its own code; previously only
  the last-initialised image worked.
- #8892 (perry#8882): late-bound `new` for classes the CJS hoister missed, and
  unresolved constructors throw `ReferenceError: <name> is not defined`.
- #8894 (perry#8883): TailCallElim's alloca walk is bounded on wide statepoint
  functions; the fixture compile drops from 92-116 min to ~10 min.
- #8924: the derived-constructor capture stash follows `super()` in every
  statement shape; the Next fixture initialises again.

build-perry-libraries.sh now builds the ext wrappers a deployment links
(`http`, `net`, `events`, ...) in one cargo invocation with the static
archives, into `<perry>/target/release/` where the daemon's compiler looks.
The daemon compiles with a scrubbed environment through Coop's `cc` shim, so
the compiler's on-demand wrapper build cannot succeed there; on developer
machines a stale `~/.local/lib/libperry_ext_*.a` was silently standing in.

prepare-next-benchmark.sh's compile RSS cap rises to 12 GB: the bounded
pipeline peaks at ~6.3 GB in the emit phase, over the old 6 GB cap.

rust-toolchain.toml stays at nightly-2026-08-20, still Perry's pin; rusqlite
stays at 0.39.

Review Change Stack

📝 Walkthrough

Walkthrough

The changes build Perry extension archives within the Perry worktree, verify the expected outputs, raise the benchmark RSS limit, and update the in-process execution documentation.

Changes

Benchmark preparation

Layer / File(s) Summary
Static Perry library build
scripts/build-perry-libraries.sh
The script builds configured static extension wrappers with Perry runtime and standard-library archives. It verifies that each expected wrapper archive exists.
Benchmark resource settings
scripts/prepare-next-benchmark.sh, crates/coop-daemon/tests/resource_benchmark.rs
The default RSS limit increases from 6144 MB to 12288 MB. The in-process execution comment records that the one-JS-heap limitation was resolved.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 4f775

The PR raises the default fixture compile limit to 12 GB, but the Linux workflow runs on a 7.75 GB host without an override, so compilation may be killed before the benchmark runs; the wrapper build can also falsely fail when Cargo uses a different target directory. These bounded readiness issues should be addressed or explicitly accepted before merge.

Keep Cargo's output directory aligned with the archive check.

If CARGO_TARGET_DIR or [build].target-dir is set, Cargo can write the archives outside $perry_root/target/release. The loop then reports ext wrapper build did not produce ... after a successful build. Pass --target-dir "$perry_root/target" or resolve Cargo's effective target directory before checking the archives.

# Compile peak for this fixture: with TailCallElim bounded (perry#8894) the
# parallel emit phase peaks at ~6.3 GB (measured on macOS and Linux), so the
# previous 6 GB cap killed every run a few minutes in. 12 GB fits that with
# headroom on any host this script is meant for; GitHub's 7.75 GB runners never
# run this fixture (the Linux proof gates it behind `next_fixture`). The
# earlier note stands as history: before #8894 every run died AT the limit, so each
# reported figure was the cap and not the peak. Raise this on a host with real
# memory; the default is a floor that keeps a constrained runner from swapping
# itself to death, not a statement about what the compile needs.

Run next_fixture only on a larger host

next_fixture gates the workflow step, but .github/workflows/linux-shared-runtime.yml still uses ubuntu-24.04 with 7.75 GB and sets no COOP_NEXT_MAX_RSS_MB. The script writes compile_max_rss_mb = 12288, so the compiler can be OOM-killed before daemon enforcement. The binary_http_roundtrip fallback also invokes the script without an override. Use a larger runner or a host-specific limit, and update the generated configuration comment.
