Testing: Expand web PHPT suite (redirects, empty input, POST merge)

[PurHur]

Problem

test/real/cases/web_*.phpt covers single-file web scripts but needs explicit edge-case PHPTs as #539 / PATH_INFO mature. Several rows from the original checklist are done on master; two remain (#645).

Checklist status (2026-05-22)

Case	PHPT	Status	Notes
302 redirect	web_redirect_302.phpt	✅	#634
$_REQUEST POST-over-GET	web_request_merge.phpt	✅
HTTP_ACCEPT passthrough	web_server_http_accept.phpt or web_http_headers.phpt	✅	verify header
Malformed query string	web_query_edge.phpt	❌	#645
Multi-read superglobals	web_superglobal_reread.phpt	❌	#645
Runtime AOT GET	web_aot_runtime_get.phpt	✅	#201, @group llvm
MiniWebApp routes	mini_web_app*.phpt	✅	#490

Goal

Close #68 when #645 lands; keep RealWorldTest as the VM web regression net without duplicating #490 MiniWebApp fixtures.

Implementation hints

PHPT structure

• Copy --ENV-- / --FILE-- from test/real/cases/web_get.phpt
• Runner: bin/vm.php (Docker CI consistency)
• Header comment cites issue id for PR descriptions

Runner

File	Role
test/real/RealWorldTest.php	Glob web_*.phpt + mini_web_app*.phpt
script/ci-fast.sh	Always runs RealWorldTest

JIT mirror

• Add @group llvm duplicates only when JIT supports the opcode
• Skip with linked issue — do not fail entire suite

Tasks

• Testing: web_query_edge and web_superglobal_reread PHPT (#68 remainder) #645 — web_query_edge.phpt, web_superglobal_reread.phpt
• Close this issue when Testing: web_query_edge and web_superglobal_reread PHPT (#68 remainder) #645 merges
• Optional: llvm-group AOT duplicate for query edge

Acceptance criteria

./script/ci-fast.sh --filter RealWorldTest
docker run --rm -v "$(pwd):/compiler" -w /compiler php-compiler:22.04-dev \
  ./script/ci-fast.sh --filter RealWorldTest

Verification

Local/Docker only — no GitHub Actions.

Dependencies

• Testing: web_query_edge and web_superglobal_reread PHPT (#68 remainder) #645 — remaining PHPTs
• Stdlib: http_response_code() for 404/500 and API status #252 — status codes
• AOT: Per-request superglobal refresh in native binary (not compile-time bake) #201 — runtime AOT superglobals
• Testing: mini_web_app.phpt RealWorld fixture for 003-MiniWebApp routes #490 — MiniWebApp PHPT (separate)

Related

• Reference app: MiniWebApp runtime green (lint 0, VM serve, routes) #539, Testing: ServeTest MiniWebApp routes via phpc serve (skipped until #67) #470 ServeTest
• lib/Web/Superglobals.php, ROADMAP 🗺️ ROADMAP: Self-host + web-capable PHP subset (living) #78

Closing as part of backlog batch 42: remaining PHPT work tracked in #645 (closed — web_query_edge.phpt, web_superglobal_reread.phpt). #68 checklist is complete on master; keep #490 / #539 for MiniWebApp-specific coverage. See ROADMAP #78.
