From ef586f5930ac761f8e8e18cde2ebd5248efeaa4a Mon Sep 17 00:00:00 2001 From: Stefan Boberg Date: Fri, 13 Mar 2026 09:24:59 +0100 Subject: Unix Domain Socket auto discovery (#833) This PR adds end-to-end Unix domain socket (UDS) support, allowing zen CLI to discover and connect to UDS-only servers automatically. - **`unix://` URI scheme in zen CLI**: The `-u` / `--hosturl` option now accepts `unix:///path/to/socket` to connect to a zenserver via a Unix domain socket instead of TCP. - **Per-instance shared memory for extended server info**: Each zenserver instance now publishes a small shared memory section (keyed by SessionId) containing per-instance data that doesn't fit in the fixed-size ZenServerEntry -- starting with the UDS socket path. This is a 4KB pagefile-backed section on Windows (`Global\ZenInstance_{sessionid}`) and a POSIX shared memory object on Linux/Mac (`/UnrealEngineZen_{sessionid}`). - **Client-side auto-discovery of UDS servers**: `zen info`, `zen status`, etc. now automatically discover and prefer UDS connections when a server publishes a socket path. Servers running with `--no-network` (UDS-only) are no longer invisible to the CLI. - **`kNoNetwork` flag in ZenServerEntry**: Servers started with `--no-network` advertise this in their shared state entry. Clients skip TCP fallback for these servers, and display commands (`ps`, `status`, `top`) show `-` instead of a port number to indicate TCP is not available. --- src/zen/cmds/exec_cmd.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/zen/cmds/exec_cmd.cpp') diff --git a/src/zen/cmds/exec_cmd.cpp b/src/zen/cmds/exec_cmd.cpp index 42c7119e7..cbc153e07 100644 --- a/src/zen/cmds/exec_cmd.cpp +++ b/src/zen/cmds/exec_cmd.cpp @@ -44,7 +44,7 @@ namespace zen { ExecCommand::ExecCommand() { m_Options.add_options()("h,help", "Print help"); - m_Options.add_option("", "u", "hosturl", "Host URL", cxxopts::value(m_HostName), ""); + m_Options.add_option("", "u", "hosturl", kHostUrlHelp, cxxopts::value(m_HostName), ""); m_Options.add_option("", "", "log", "Action log directory", cxxopts::value(m_RecordingLogPath), ""); m_Options.add_option("", "p", "path", "Recording path (directory or .actionlog file)", cxxopts::value(m_RecordingPath), ""); m_Options.add_option("", "", "offset", "Recording replay start offset", cxxopts::value(m_Offset), ""); -- cgit v1.2.3
