Regression: hash_hmac_algos Reflection missing array return — Zend array (ext/hash/hash.stub.php)

Problem

hash_algos() Reflection advertises array return, but sibling hash_hmac_algos() has no return type (ReflectionFunction::hasReturnType() === false). Zend stub is function hash_hmac_algos(): array. Probed 2026-08-06 VM @ bf5802236.

Function	Zend Reflection return	VM (2026-08-06)
hash_algos	array	array
hash_hmac_algos	array	<none>

Runtime list itself is fine (non-empty HMAC algo list).

php-src reference

• php/php-src ext/hash/hash.stub.php — function hash_hmac_algos(): array {}

PHP implementation target

• ext/hash/ Module / Internal arginfo for hash_hmac_algos — add array return metadata to match hash_algos; PHP-only, no C

Repro

./script/docker-exec.sh -- bash -lc 'php bin/vm.php -r '\''
$r = new ReflectionFunction("hash_hmac_algos");
echo "hmac return=", $r->hasReturnType() ? (string)$r->getReturnType() : "NONE", "\n";
$r2 = new ReflectionFunction("hash_algos");
echo "algos return=", $r2->hasReturnType() ? (string)$r2->getReturnType() : "NONE", "\n";
'\'''

Done when

• ReflectionFunction('hash_hmac_algos')->getReturnType() is array (matches hash_algos / Zend)
• Compliance .phpt guard under test/compliance/cases/
• php-src-strict; no php-compiler-strict shortcut

claim: PHP Compiler Ext — I/O & Crypto — starting this run

Pre-flight (this host):

• docker info: ok
• php script/bootstrap-inventory.php --check: red — stale docs/bootstrap-inventory.md (method-count drift on SprintfJitHelper / VmPhpCoreConstants / CompilerVersion; pre-existing on master, not this issue)
• ./script/release-readiness.sh --json: still running at claim time
• Repro confirmed: hash_hmac_algos Reflection return=NONE, hash_algos=array

Fix: stub hash_hmac_algos(): array in BuiltinInternalArgInfo (php-src ext/hash/hash.stub.php).

[PurHur]

Merged #28186 (d8ad62ab3)

Fix

BuiltinInternalArgInfo::stubReturnTypeLabelForFunction('hash_hmac_algos') → array (php-src ext/hash/hash.stub.php). Runtime list unchanged.

Verification

php bin/vm.php -r '…'
hmac return=array
algos return=array

vendor/bin/phpunit test/unit/BuiltinParamNamesAliasTest.php --filter testHashHmacAlgosStubReturnArray
OK (1 test, 3 assertions)

vendor/bin/phpunit test/compliance/HashHmacAlgosReflectionReturnVMTest.php
OK (1 test, 1 assertion)

Note: full VMTest data provider is broken on master by invalid dom_token_list_value_tostring.phpt (starts with <?php); this PR uses a dedicated compliance runner instead.
