* Unix Domain Socket auto discovery (#833)Stefan Boberg2026-03-131-12/+12
| | | | | | | | 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.
* Various fixes to address issues flagged by gcc / non-UE toolchain build (#621)Stefan Boberg2025-11-011-1/+1
| | | | | | | | | | | | | | | | | | | | * gcc: avoid using memset on nontrivial struct * redundant `return std::move` * fixed various compilation issues flagged by gcc * fix issue in xmake.lua detecting whether we are building with the UE toolchain or not * add GCC ignore -Wundef (comment is inaccurate) * remove redundant std::move * don't catch exceptions by value * unreferenced variables * initialize "by the book" instead of memset * remove unused exception reference * add #include <cstring> to fix gcc build * explicitly poulate KeyValueMap by traversing input spans fixes gcc compilation * remove unreferenced variable * eliminate redundant `std::move` which gcc complains about * fix gcc compilation by including <cstring> * tag unreferenced variable to fix gcc compilation * fixes for various cases of naming members the same as their type
* add ability to limit concurrency (#565)Stefan Boberg2025-10-101-1/+1
| | | | | | | | | | | | effective concurrency in zenserver can be limited via the `--corelimit=<N>` option on the command line. Any value passed in here will be used instead of the return value from `std::thread::hardware_concurrency()` if it is lower. * added --corelimit option to zenserver * made sure thread pools are configured lazily and not during global init * added log output indicating effective and HW concurrency * added change log entry * removed debug logging from ZenEntryPoint::Run() also removed main thread naming on Linux since it makes the output from `top` and similar tools confusing (it shows `main` instead of `zenserver`)
