From 3a0d9340810a8808d963135a884f50d08442ac67 Mon Sep 17 00:00:00 2001 From: nsfisis Date: Thu, 25 Jun 2026 16:27:53 +0900 Subject: test: port 59 autoload/vcs/installer/util/command tests; fix output capture Port autoload_generator (24), bitbucket (14), suggested_packages (11), git_driver (6), archive_manager (3), and a bump command test. Fix the ApplicationTester output-capture root cause (php://memory streams must be readable regardless of fopen mode). Implement posix_getuid/geteuid, the PCRE 'A' anchored modifier, php_strip_whitespace, stream_get_wrappers, is_callable scalars; fix preg_quote angle-bracket escaping and class-map parser regexes.
