Stdlib: stream_socket_accept() missing — TCP server accept on stream resource fatal (ext/standard/streamsfuncs.c) #15346

Category

stdlib · php-src-strict · stream sockets phase 2

Problem

stream_socket_server() / stream_socket_client() exist (#3202), but stream_socket_accept() is not registered — function_exists('stream_socket_accept') is false on VM while Zend returns true. Blocking TCP servers and test harnesses cannot accept connections on stream resources.

Related cluster: #6043 (shutdown/get_name/UDP), #4610 (stream_socket_enable_crypto).

Verified 2026-07-03 on master.

php-src reference

• php/php-src ext/standard/streamsfuncs.c — PHP_FUNCTION(stream_socket_accept)
• php/php-src main/streams/streams.c — php_stream_sock_ops accept path

PHP implementation target

• ext/standard/ stream socket builtin (PHP lowering + thin accept(2) ABI if needed)
• Reuse existing stream resource wrappers from stream_socket_server()

Repro

test/repro/maintainer_gap_stream_socket_accept.php

./script/docker-exec.sh -- bash -lc 'php test/repro/maintainer_gap_stream_socket_accept.php'           # true
./script/docker-exec.sh -- bash -lc 'php bin/vm.php test/repro/maintainer_gap_stream_socket_accept.php'  # undefined function

Done when (php-src-strict)

• Repro prints true on VM
• Timeout / invalid-server-resource errors match Zend
• Capability matrix lists stream_socket_accept VM=yes
