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/zenhttp/httpclientauth.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/zenhttp/httpclientauth.cpp') diff --git a/src/zenhttp/httpclientauth.cpp b/src/zenhttp/httpclientauth.cpp index 1ebf1f949..c42841922 100644 --- a/src/zenhttp/httpclientauth.cpp +++ b/src/zenhttp/httpclientauth.cpp @@ -105,7 +105,7 @@ namespace zen { namespace httpclientauth { } if (Hidden) { - ProcOptions.Flags |= CreateProcOptions::Flag_NoConsole; + ProcOptions.Flags |= CreateProcOptions::Flag_NoWindow; } const std::filesystem::path AuthTokenPath(std::filesystem::temp_directory_path() / fmt::format(".zen-auth-{}", Oid::NewOid())); -- cgit v1.2.3
