* fix(compiler): support first-class callable of internal functions
PHP 8.1 `foo(...)` builds a Closure from a single VariadicPlaceholder
argument instead of calling foo. Two paths mishandled it:
- checkInternalFunctionArgCount() counted the placeholder as a real
argument, so first-class callables of internal functions requiring 2+
parameters (e.g. `posix_kill(...)`) failed with a bogus "expects at
least N arguments, 1 given".
- The math-function return-type optimization read `$expr->args[0]->value`
on callables such as `round(...)`, crashing on the undefined
VariadicPlaceholder::$value property.
Guard both with isFirstClassCallable() so the expression falls through to
Closure (Type::OBJECT) resolution.
* fix(compiler): infer builtin callables before return optimizations

* optimize: convert for-loop post-inc/dec to prefix to avoid zval copy
For-loop post-expressions (third clause of `for (init; cond; post)`) always
discard the return value, so $i++ is semantically identical to ++$i in this
context. Converting to prefix increment/decrement avoids the zval copy +
destructor overhead from operator++(int)'s return value, saving ~6ns per
increment per loop iteration.
Changes:
- LoopControlTrait: convert PostInc→PreInc, PostDec→PreDec in for-loop
post-expressions only (while/do-while body untouched)
- Add phpunit test verifying generated C++ contains ++i/--i for for-loops
and retains i++ in while/do-while bodies

nested, mixed, and while/do-while cases

* fix(preprocessor): reject variadic promoted properties and callable property/constant types
Two promotion/type gaps against Zend (probed on 8.4.13):
- `__construct(public int ...$x)` was accepted and even registered
the property before the variadic-position check ran. A variadic
parameter collects its arguments into an array, so there is no single
value to promote; Zend fatals with "Cannot declare variadic promoted
property". The check now precedes the property registration.
- `callable` is a calling-scope-dependent type, so Zend forbids it in
property types (declared, promoted, interface hooked) and class
constant types (class and interface), bare or as a nullable/union
member: "Property A::$x cannot have type ?callable" /
"Class constant A::X cannot have type callable". Intersection
members are left to the compound-type validation, which rejects
every non-class standard type there.
`void`/`never` property and parameter types were already rejected by
parseTypeDecl ("The type `void`/`never` is allowed only for return
type") - verified, no change needed; union members are covered by the
compound-type validation.
* test(preprocessor): cover promotion and property/constant type rules
* fix(preprocessor): reject callable inside intersection and DNF types
typeDeclContainsCallable() deliberately skipped IntersectionType, so a
DNF-nested callable such as `public (Traversable&callable)|stdClass
$value;` sailed past the property checks and died in gen_stub on
assert(!$type->isBuiltin); a bare `Traversable&callable` property
compiled outright.
Zend rejects callable while compiling the intersection type itself,
with its own diagnostic ("Type callable cannot be part of an
intersection type", probed on 8.4.13), in every declaration context and
ahead of the property/constant-specific bans — `callable|(Traversable&
callable)` reports the intersection conflict, not the property one.
A dedicated assertTypeDeclIntersectionsHaveNoCallable() walk (nullable,
union, intersection members) now runs before the existing
typeDeclContainsCallable() checks in all contexts this branch guards:
class properties, promoted properties (both via addClassProperty),
typed class constants, and interface properties/constants. Tests cover
the bare intersection member, DNF in first and second union member,
the promoted and constant/interface variants, and a callable-free DNF
property that must keep compiling.
* fix(preprocessor): validate callable intersections on the common type-declaration path
assertTypeDeclIntersectionsHaveNoCallable() was invoked only from the
property and class/interface-constant paths, so the same invalid type
in a function parameter or return declaration bypassed the check and
reached the later generator path:
function consume(Traversable&callable $value): void {}
function produce(): Traversable&callable {}
Zend rejects both while compiling the type itself ("Type callable
cannot be part of an intersection type", probed on 8.4.13), in every
declaration context.
The walk now lives in parseTypeDecl(), the declaration funnel behind
resolveTypeDecl() that parameters, returns, properties, promoted
properties, class and interface constants, and interface hooked
properties already flow through; the per-context calls are gone, and
the diagnostic points at the offending intersection member. Closure
and arrow-function signatures resolved no full type node anywhere, so
doGenClosure() now routes them through the same funnel - except bare
class names, which the native-object walk there already resolves (and,
inside trait methods, rewrites) via parseTypeDecl().
The property and constant paths resolve the declaration before
applying their own bare/nullable/union callable bans, so a type like
`callable|(Traversable&callable)` keeps reporting the intersection
conflict first, as Zend does.
New negative tests: parameter and return intersections, callable in a
DNF parameter member, and closure parameter and return intersections
(each probed against Zend 8.4.13); positive tests keep bare `callable`
parameters and callable-free DNF properties compiling.
* fix(gen_stub): register enum-case class constants as persistent AST constants
A class constant valued by an enum case was registered with the folded
scalar (the backing value, or the case name for pure cases), so
constant('K::CB'), $cls::CB and reflection observed an int/string where
PHP has the case object, and K::CB === E::B was false on every dynamic
path. Enum case objects have request lifetime and can never sit in the
persistent class-entry tables, in any request-init rebinding scheme
least of all: writing a request-owned object into the shared table is
unsafe under concurrent ZTS requests.
Reuse the engine's own mechanism for internal enums instead: the
constant is declared as a persistent IS_CONSTANT_AST holding the
Enum::Case fetch, so Zend separates the class constants table into
request-local mutable storage on first access, evaluates the fetch
there, and cleans it up at request shutdown. Identity is preserved for
static access, constant(), dynamic class access and reflection, with no
module-lifecycle hooks and no registration-order sensitivity.
Case identity flows through compile-time constant evaluation as an
EnumCaseRef value instead of a scalar, so it also survives constant
expressions (true ? E::A : E::B), constant chains, typed class
constants (declared type and AST value are registered together), and
internal enum cases such as RoundingMode::HalfEven, which previously
aborted stub generation. The runtime expression path (php::getEnumCase)
is unchanged.
The preprocessor also no longer reads the raw ->value property off
arbitrary case expressions (`case A = 1 + 1;` warned and was recorded
as a pure case): only literal backing values are recorded eagerly, and
no compile-time consumer needs the evaluated scalar - gen_stub
evaluates the registration value from the AST itself.
* fix(gen_stub): constrain enum-case AST registration to class constants
The persistent IS_CONSTANT_AST representation leaked into property and
parameter defaults, whose persistent tables reject refcounted zvals:
startup died with "Internal zvals cannot be refcounted". EvaluatedValue
now carries the case identity in a dedicated field while its value
degrades to what those consumers read before case identity existed
(the host case object for internal enums, the literal backing value or
case name for compiled ones), and only class-constant registration opts
into the AST. Property/parameter defaults keep flowing through their
existing runtime-restore machinery unchanged.
Also parenthesize a folded constant operand before appending a member
access: the C++ ternary of `const VALUE = cond ? E::A : E::B;` bound
`.attr("value")` to its else branch only, so `K::VALUE->value`
evaluated to the case object instead of its backing value.
* fix(gen_stub): give persistent AST constants a complete teardown lifecycle
destroy_zend_class() asserts (in debug builds) that every persistent
AST constant remaining on an internal class is CONST_ENUM_INIT, and its
teardown frees only the allocation referenced by Z_AST — the previous
representation left a CLASS_CONST root behind (assertion failure at
shutdown on 8.4/8.5 debug builds) and leaked the two separately
allocated children.
The AST is now built in one contiguous persistent allocation (ast_ref,
root, both zval children — mirroring Zend's own persistent enum AST
builder), and every generated file with AST constants emits a release
function that runs from the module's MSHUTDOWN, before Zend's class
teardown: it frees the single block and restores the constant slot to
null, so destroy_zend_class() never sees a foreign AST. Request-local
mutable copies are unaffected (no request is live at MSHUTDOWN).
CONST_ENUM_INIT itself is not usable here: that node constructs a new
case object rather than fetching the canonical registered one, which
would break case identity again.
* fix(codegen): reject lifecycles that cannot release AST constants
The typephp_release_ast_constants_*() teardown ran only from MSHUTDOWN,
which is not a general pre-class-destruction hook: for a
MODULE_TEMPORARY module loaded through dl(), module_destructor() runs
clean_module_classes() before the shutdown callback, so the foreign
ZEND_AST_CLASS_CONST reached destroy_zend_class() first and still
tripped the debug assertion; and a MINIT that fails after registering
such a constant never sets module_started, so MSHUTDOWN is not
guaranteed to run at all.
The generated module now enforces the lifecycle contract instead of
assuming it. When the module declares any enum-case AST constant, MINIT
opens with a guard that rejects MODULE_TEMPORARY (zend_error E_WARNING,
return FAILURE) before a single class is registered — with nothing in
the class table, teardown is trivially safe. MINIT is also restructured
so that every step that can return FAILURE precedes the first
register_class_*() call: the AST constants are installed by the
infallible tail (class registration, then symbol registration), so a
FAILURE return can never leave a foreign AST in the persistent tables.
The generator itself throws if a future change introduces a FAILURE
return after registration begins. The MSHUTDOWN release is unchanged
and remains the supported, persistent-module path.
EnumCaseAstConstantLifecycleTest asserts the guard exists exactly when
AST constants exist, that it precedes every registration step, that no
FAILURE return follows the first class registration, and that MSHUTDOWN
releases the constants before any other teardown. The enum-case phpt
gains a never-accessed constant so the full process shutdown it already
performs also covers a pristine persistent AST; a dl()-path phpt is not
feasible because the harness only builds standalone binaries whose
module is registered persistently (documented in the test file).
* fix(preprocessor): enforce Zend interface member declaration rules
parseInterface accepted several declarations Zend rejects at compile
time (all wordings probed on 8.4.13, which renamed the modifier errors
to "must not be abstract/final"):
- interface method with a body ("Interface function I::f() cannot
contain body")
- private/protected interface method ("Access type for interface
method I::f() must be public")
- explicit `abstract` modifier on an interface method ("Interface
method I::f() must not be abstract")
- `final` interface method ("Interface method I::f() must not be
final")
- private/protected interface constant ("Access type for interface
constant I::X must be public"); `final` interface constants remain
legal per PHP 8.1
- explicit `abstract` on an interface hooked property ("Property in
interface cannot be explicitly abstract...")
- `interface I extends A` where A is a known class, enum, or trait
("I cannot implement A - it is not an interface"); only checked when
A's declaration has already been prepared - a parent declared later
is left to the Translator (deferred to integrator)
- the same interface listed twice in extends ("Interface I cannot
implement previously implemented interface A")
Zend's precedence for combined modifier violations (visibility, then
abstract, then final, then body) is preserved.
* fix(translator): validate same-name methods when interfaces merge
Two interfaces declaring the same method were never cross-checked:
`interface J extends I1, I2` and a class implementing both compiled
even when the declarations were mutually incompatible (Zend:
"Declaration of I1::f(): int must be compatible with I2::f(): string").
The first-seen declaration is now validated as an override of every
later one, mirroring Zend's merge order; diamond inheritance of one
original declaration never conflicts, and a method the class chain
defines silences the pairwise check (it is validated against each
interface individually instead) — all probed against Zend 8.4.
* fix(translator): reject an interface extending a class, validate merged methods
An interface can only extend other interfaces: naming a class either
fataled with a misleading missing-symbol message (declaration seen
earlier) or compiled silently (declaration appearing later). The
translation phase now rejects both with Zend's wording.
Same-name methods arriving from several extended interfaces (or from
several interfaces a class implements without defining the method) were
never cross-checked; the first-seen declaration is now validated as an
override of every later one, matching Zend's merge order, with diamond
inheritance of one original declaration exempt.
* fix(translator): guard the interface method table against extends cycles
getEffectiveInterfaceMethodTable() recursed forever on a cyclic extends
graph (interface A extends B; interface B extends A). Zend never reaches
this state - declarations are linked one at a time, so the first one
already fails with 'Interface "B" not found' - but ahead-of-time the
whole graph exists before linking, so the cycle must be detected.
Track the tables being built in a visiting set (cleared with
try/finally) and fail promptly with the same stable diagnostic the
constants table uses ('Interface inheritance cycle detected at ...'),
so the helper is safe regardless of which validation pass reaches the
cycle first. Diamond (non-cyclic) graphs still converge through the
memoized table.
Covered by a negative test on the two-interface cycle; the diamond case
is already exercised by interface_collision_valid.php.
* fix(preprocessor): enforce Zend readonly property declaration rules
The readonly checks previously lived only in the Native-class branch;
ZendVM-backed classes accepted declarations Zend rejects at compile
time. addClassProperty now enforces, for declared and promoted
properties alike (probed against Zend 8.4.13):
- readonly property with a default value ("Readonly property A::$x
cannot have default value") - a readonly property carries runtime
initialization state, so a compile-time default is meaningless
- untyped readonly property, including untyped promoted readonly ctor
params ("Readonly property A::$x must have type")
- static readonly ("Static property A::$x cannot be readonly")
- a `readonly class` applies the same three rules to every property:
the class-level Modifiers::READONLY flag (already recorded on
ClassDef->flags for the Translator-side inheritance check) is OR-ed
into the per-property check
Promoted readonly params keep accepting parameter defaults: the default
belongs to the constructor argument, not the property (Zend-verified).
The inheritance_error_prop_readonly fixture used `readonly int $x = 2`,
which Zend itself rejects with the default-value error before ever
reaching the readonly-mismatch link error; the default is dropped so the
fixture still exercises the inheritance mismatch.
* fix(translator): enforce readonly-class inheritance in both directions
Zend seals readonly-ness across a hierarchy: a non-readonly class cannot
extend a readonly one and vice versa. Both directions compiled silently.
* fix(translator): complete readonly-class contracts for traits, internal parents and attributes
Three readonly-class rules Zend enforces at compile time were still
accepted (all probed on 8.4.13):
- A trait property keeps its own declaration; the consuming class's
readonly modifier does not upgrade it, so composing a non-readonly
(or static, which can never be readonly) trait property into a
readonly class fails: "Readonly class C cannot use trait with a
non-readonly property T::$value". The check runs in composeTraitAst's
property pass, which also matches Zend's naming of the directly used
trait when the property originates in a nested trait. A trait property
declared readonly composes fine.
- The readonly inheritance check only covered compiled parents; classes
extending internal ones skipped it entirely, so `readonly class C
extends ArrayObject {}` compiled. Internal parents now consult host
reflection (ReflectionClass::isReadOnly), keeping the contract
two-directional: the host runtime also knows internal readonly classes
(BcMath\Number, Dom\NamespaceInfo — both final in 8.4, so only the
readonly-child direction is reachable today).
- #[AllowDynamicProperties] contradicts readonly semantics (every
property is readonly and declared); Zend rejects the combination:
"Cannot apply #[AllowDynamicProperties] to readonly class C". The
pre-existing readonly-class.phpt carried exactly this invalid
combination and is adjusted to stay a valid positive test.
* fix(preprocessor): enforce property-hook placement rules for class properties
The interface path already validated hook placement; class and trait
properties accepted every combination. parseClassPropertyDef now
mirrors Zend's compile-time rules (probed on 8.4.13, including the
precedence order static -> readonly -> abstract rules):
- hooks on a static property ("Cannot declare hooks for static
property")
- hooks on a readonly property, including properties made readonly by
a `readonly class` ("Hooked properties cannot be readonly")
- `abstract` on a hook-less property ("Only hooked properties may be
declared abstract")
- abstract hooked property with a default value ("Cannot specify
default value for virtual hooked property A::$x")
- abstract hooked property whose hooks all have bodies ("Abstract
property A::$x must specify at least one abstract hook")
- abstract hooked property in a non-abstract class; traits stay exempt
(the consuming class satisfies the hook) and enums are already
rejected by the property ban
- bodiless hook on a non-abstract property, in classes and traits
("Non-abstract property hook must have a body"); previously the
lowering fabricated a concrete backing-store accessor for it
* test(preprocessor): cover property-hook placement rules
* fix(preprocessor): reject abstract-private, abstract-final and final-private hooks
Three hook-level modifier conflicts Zend rejects at compile time were
still accepted by the class/trait property path (all probed on 8.4.13):
- `abstract private int $x { get; }` — an abstract (bodiless) hook must
be implemented by a subclass, which private visibility forbids
("Property hook cannot be both abstract and private"). Unlike abstract
private trait methods, Zend does NOT exempt traits from this rule.
- `abstract public int $x { final get; }` — a bodiless hook must stay
overridable to ever gain a body ("Property hook cannot be both
abstract and final").
- `private int $x { final get => 1; }` — a final hook on a private
property is meaningless because private members cannot be overridden
("Property hook cannot be both final and private").
Diagnostic precedence follows Zend: static, then readonly, then the
per-hook final+private conflict (which wins over both abstract
conflicts: `abstract private int $x { final get; }` reports
final+private), then per bodiless hook abstract+private before
abstract+final, all ahead of the default-value and
at-least-one-abstract-hook rules. Protected abstract hooks remain
legal in classes and traits.
* fix(codegen): keep Zend operand read order around hoisted side effects
Lowering a later call argument or concat operand that materializes
captured statements (an assignment, a call result) appended them to the
enclosing statement, executing the side effect before earlier operands
were read: two($j, $j = 5) with $j = 1 produced "5,5" (Zend "1,5") and
$m . "," . ($m = 9) produced "9,9" (Zend "1,9").
Call arguments: Zend SENDs strictly left to right, so when a later
argument hoists statements, every earlier by-value plain-variable
argument is snapshotted into a temporary at its own argument position.
By-reference parameters, unpacked arguments, $this and $GLOBALS are
left alone.
Concat chains: Zend reads a CV operand when its CONCAT opcode executes,
so in the left-associated chain the first two items are read together
at the first op (after both items' side effects: $s . ($s = 'b') . $s
is "bbb") and each later item after the side effects of everything up
to itself. The flattened braced-list lowering now snapshots a
plain-variable item exactly at that read position, deferring the first
item's snapshot until the second item has been lowered.
Plain arithmetic is intentionally unchanged: Zend's ADD reads the CV at
op time, so $k + ($k = 5) is 10 in both worlds, and the existing
codegen already matches.
* test(codegen): platform-neutral integer-literal suffixes in eval-order assertions
* fix(codegen): detect wrapped side effects when ordering operand reads
Zend sends call arguments strictly left to right and reads a concat
operand's CV when its opcode executes: an assignment nested in a later
argument runs after every earlier by-value argument has been sent, so
pairValue($i, (int) ($i = 5)) passes the old value ("1,5"), and the
same holds when the assignment is wrapped in !, unary +/-, ~, or @.
shouldMaterializeOrderedOperand() only descended through BinaryOp
nodes, so an assignment inside any other expression wrapper was not
classified as side-effecting: no earlier operand was snapshotted and
the assignment could even stay inline in the C++ argument list
(php::toInt(i = 5LL)), mutating the variable at an unsequenced point.
Deriving the decision from the captured statements lowering produces
would miss exactly these inline cases, so the classifier now recurses
structurally through every sub-expression: any wrapper of a
side-effecting node is itself side-effecting. Closure and arrow
function bodies do not run at creation time and stop the walk; throw,
yield, yield from, and backtick expressions join the side-effecting
leaves.
Zend's ADD opcode still reads its CV at op time, so $k + ($k = 5)
keeps its existing codegen (10 in both worlds, no snapshot).
* fix(codegen): type materialized wrapper operands as dynamic temporaries
A wrapper expression around a side effect (-strlen($s), a cast, error
suppression) is now materialized for evaluation order, but the temp-type
fallback typed it by the detected PHP type. The lowered C++ can still be
dynamic — an unqualified namespaced call lowers to php::call(...), a
Variant — so a php::Int temporary failed to compile in the self-build.
Follow the call/binary-op policy: native scalar types only in
native-types mode, otherwise a dynamic temporary.
* fix(codegen): route typed division, int modulo and shifts through PHP operators
Typed int/int and float-typed division fell through to a raw C++ '/':
7 / 2 on zend_long operands truncated to 3 where PHP returns 3.5,
integer division by zero was undefined behavior and float division by
zero produced INF, while PHP raises a catchable DivisionByZeroError in
both cases; PHP_INT_MIN / -1 also has UB in C++ but promotes to float
in PHP. The '%' guard only routed through php::fn::mod when NOT both
operands were int, so both-int modulo kept raw C++ '%' (UB for a zero
divisor and for PHP_INT_MIN % -1, which PHP defines as 0). Dynamic int
shifts were raw C++ too: PHP defines counts >= the word size as 0 (or
-1 for negative right shifts) and raises ArithmeticError for negative
counts, both undefined in C++.
Route all of these through the encapsulated php::Var operators /
php::fn::mod in non-native mode, matching the existing +/-/* pattern.
Constant folds are untouched; constant shifts that C++ defines
identically to PHP still emit raw operators.
* fix(parser): defer literal zero divisors to the runtime DivisionByZeroError
A literal `/ 0` or `% 0` (including `/=` and `%=`) was a compile-time
fatal, rejecting valid PHP: Zend compiles it and raises a catchable
DivisionByZeroError only when the statement executes, so dead or
guarded code like `if ($cond) { $x = 1 % 0; }` must compile. The
equivalent spellings `1 % (1 - 1)` and `10 / ZERO` were already
accepted and lowered to the catchable runtime error.
Give the literal spelling the same lowering: route the operation
through the encapsulated Variant operators (compound assignments on
Variant slots already defer via operator/= and operator%=), keep a
compile-time warning in normal mode, and keep the fatal in native mode
where the C++ operation would be undefined behavior.
The six OperatorTest cases asserting the old compile-time fatal now
assert the runtime-error lowering instead.
* test(operator): platform-neutral literal suffixes, PHP division on typed ints
The literal-division assertions hardcoded the macOS zend_long suffix
(LL); Linux emits L, so they now match either. native-type.phpt
asserted the truncating int division this change removes: division on
typed int operands follows PHP semantics in non-native mode, consistent
with the pre-existing + - * routing (use native_types keeps raw
division), so std::int(10) / 4 is now float(2.5).
* fix(codegen): literal zero divisors on native scalar slots raise the runtime error
Downgrading the literal-zero compile fatal to a warning exposed the raw
C++ compound path on typed native slots: `int $value; $value /= 0`
compiled to `value /= php::toInt(0L)` and killed the process with
SIGFPE instead of the catchable DivisionByZeroError (`%= 0` likewise;
float `/= 0.0` produced INF). A proven zero divisor always throws
before any assignment happens, so the whole compound lowers to the
PHP-semantics binary operation through php::Var and the target is left
untouched. Native-types mode keeps the compile-time rejection.
* fix(codegen): exclude explicit native scalars from PHP arithmetic routing
std::int()/std::float() opt into native C++ arithmetic independently of
the file-wide native_types declaration, and the existing + - * routing
already honors that via isExplicitNativeArithmeticExpr(). The new
division, both-int modulo and dynamic shift branches, and the
literal-zero compound lowering, bypassed it: std::int(10) / 4 changed
from int(2) to float(2.5) and native-type.phpt was updated to encode
the regression.
Every new PHP-semantics branch now skips explicitly native operands,
native-type.phpt is restored to int(2), and a proven zero divisor on an
explicit native slot keeps the compile-time rejection used by
native_types mode instead of being silently rerouted to PHP semantics.
Boundary coverage added on both sides: ordinary typed parameters keep
PHP behavior (7 / 2 is 3.5, -7 % 2 is -1) while std::int()/std::float()
keep native division, modulo and shifts.
