From 21c2abb1bde697c31bee562465cb986a0429a299 Mon Sep 17 00:00:00 2001 From: Stefan Boberg Date: Tue, 24 Mar 2026 15:47:23 +0100 Subject: Subprocess Manager (#889) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a `SubprocessManager` for managing child processes with ASIO-integrated async exit detection, stdout/stderr pipe capture, and periodic metrics sampling. Also introduces `ProcessGroup` for OS-backed process grouping (Windows JobObjects / POSIX process groups). ### SubprocessManager - Async process exit detection using platform-native mechanisms (Windows `object_handle`, Linux `pidfd_open`, macOS `kqueue EVFILT_PROC`) — no polling - Stdout/stderr capture via async pipe readers with per-process or default callbacks - Periodic round-robin metrics sampling (CPU, memory) across managed processes - Spawn, adopt, remove, kill, and enumerate managed processes ### ProcessGroup - OS-level process grouping: Windows JobObject (kill-on-close guarantee), POSIX `setpgid` (bulk signal delivery) - Atomic group kill via `TerminateJobObject` (Windows) or `kill(-pgid, sig)` (POSIX) - Per-group aggregate metrics and enumeration ### ProcessHandle improvements - Added explicit constructors from `int` (pid) and `void*` (native handle) - Added move constructor and move assignment operator ### ProcessMetricsTracker - Cross-platform process metrics (CPU time, working set, page faults) via `QueryProcessMetrics()` - ASIO timer-driven periodic sampling with configurable interval and batch size - Aggregate metrics across tracked processes ### Other changes - Fixed `zentest-appstub` writing a spurious `Versions` file to cwd on every invocation --- src/zencore/logging.cpp | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'src/zencore/logging.cpp') diff --git a/src/zencore/logging.cpp b/src/zencore/logging.cpp index 828bea6ed..5ada0cac7 100644 --- a/src/zencore/logging.cpp +++ b/src/zencore/logging.cpp @@ -414,6 +414,13 @@ InitializeLogging() { ZEN_MEMSCOPE(ELLMTag::Logging); + EnableVTMode(); + +#if ZEN_PLATFORM_WINDOWS + // Enable UTF-8 output so multi-byte characters render correctly via WriteFile + SetConsoleOutputCP(CP_UTF8); +#endif + TheDefaultLogger = LoggerRef(*Registry::Instance().DefaultLoggerRaw()); g_LoggingInitialized = true; } -- cgit v1.2.3
