Test Compiling Speed

[PurHur]

Problem

Full ./script/ci-local.sh (JIT + AOT lint + link) is too slow for tight iteration loops. Contributors need a fast gate that still catches VM/compliance regressions.

Goal (achieved on master)

Mode	Command	LLVM	Typical use
Fast	./script/ci-fast.sh, make test-fast, phpc test --fast	skipped	daily iteration
Full	./script/ci-local.sh, make test-docker	phased aot-lint → jit → aot-link	pre-merge

#501 memory caps apply to both paths via script/ci-common.sh.

Implementation notes

• Phased llvm groups exit subprocesses between stages (#436 design)
• MINIWEBAPP_VM_CLI_GATE=1 default in ci-fast.sh (DevEx: MINIWEBAPP_VM_CLI_GATE runs MiniWebApp VM CLI tests in ci-fast #597)
• Capability/bootstrap --check in ci-common.sh

Acceptance criteria

./script/ci-fast.sh
./script/ci-local.sh   # slower; required before merge

Docker:

./script/docker-ci-local.sh        # full
./script/docker-ci-local.sh --fast # if supported, else ci-fast inside container

CI de-duplication

• Not CI: Run JIT compliance tests in CI (fix LLVM skip in PHPUnit) #98 (JIT must run in full gate)
• Not Infrastructure: LLVM 9 → 14+ upgrade and CI matrix #174 (LLVM version bump)
• Not CI: Add GitHub Actions workflow for PHPUnit (VM, compliance, real, AOT) #47 / Disable github actions for now #394 (GHA optional only)

Links

• Docs: Local CI matrix (host, Docker, GHA skips) in README #245 — CI matrix doc
• ROADMAP 🗺️ ROADMAP: Self-host + web-capable PHP subset (living) #78 Phase 0

Also it looks like this is using a huge amount of ram (>256gb) we need to limit that also. We have 126gb available

[PurHur]

Closed via #439: tiered ci-fast.sh + phased LLVM ci-local.sh with PHP_COMPILER_CI_RAM_GB memory cap.

[PurHur]

100gb for a run is too much. We need less. When 4 runs are running in parallel we only would have 32gb for each. Do 30gb as safety margin. But only do that if this will not break our compiling.

[PurHur]

Closed — implemented locally (batch 24 de-dupe):

• Fast gate: ./script/ci-fast.sh, phpc test --fast, make test-fast — VM/compliance + serve (no @group llvm).
• Full gate: ./script/ci-local.sh, phpc test, make test — phased aot-lint → jit → aot-link + Testing: Optional examples-web-smoke --aot gate in ci-local when LLVM present #444 AOT examples-web-smoke.

Do not track a separate “GHA compile speed” issue; use the scripts above on host or in php-compiler:22.04-dev.

Resolved — linked to local CI stack (batch 28)

Implemented as script/ci-fast.sh / phpc test --fast / make test-fast (VM + compliance, no LLVM compile). Full gate remains script/ci-local.sh (#250 JIT guard, #98 root cause).

GitHub Actions intentionally disabled (#394 ✅). Document verification paths in #245, not .github/workflows/*.

ROADMAP #78.

[PurHur]

Backlog de-dupe (batch 70): README still links #436 for local/Docker CI policy (remote GHA/Circle disabled). This closed issue title (“Test Compiling Speed”) is not the active tracker.

Topic	Canonical
Local full/fast CI	./script/ci-local.sh, ./script/ci-fast.sh, #245 ✅ docs/local-ci-matrix.md
No GHA merge gates	#394 ✅
LLVM 14+ upgrade	#174 (not a CI duplicate)
North Star 1 gate flips	#1760

Do not reopen #436 for CI work — comment on #78 ROADMAP or open a focused child issue.
