* Unix Domain Socket auto discovery (#833)Stefan Boberg2026-03-131-7/+7
| | | | | | | | 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.
* 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`)
* move rpcrecorder out from cache subfolder (#552)Dan Engelbrecht2025-10-031-1/+1

* cache RPC replay fixes (minor) (#544)Stefan Boberg2025-10-031-0/+9
| | | | | * fixes misleading server side log message when using `--onhost` * fixed `--onhost` behaviour in zen (no longer replays twice)
* fix for RPC replay issue (wrong content-type) (#536)Stefan Boberg2025-10-021-26/+4
| | | | | likely fall-out from HttpClient refactor. The content type used to be explicit via headers but is now taken from the `IoBuffer` also fixed issue which meant the original request session ID would also not be propagated as intended
* make cpr a HttpClient implementation detail (#517)Stefan Boberg2025-09-291-60/+12
| | | | | these changes remove cpr from anything which is not `HttpClient` internals. The goal is to eventually replace cpr with a more direct curl interface to eliminate cpr since it's proven problematic due to their development practices which frequently breaks APIs and prevents us from updating vcpkg. But this PR is limited to refactoring existing cpr code to use `HttpClient` instead.
* add EMode to WorkerTheadPool to avoid thread starvation (#492)Dan Engelbrecht2025-09-101-1/+2
| | | - Improvement: Add a new mode to worker thread pools to avoid starvation of workers which could cause long stalls due to other work begin queued up. UE-305498
* refactor zen command return value handling (#487)Dan Engelbrecht2025-09-051-31/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Improvement: Use consistent language for command line argument parsing errors - Improvement: Changed zen command parsing errors to output help first and error last to make it easier to spot the error - Improvement: Refactor zen command return codes to conform to valid Linux range (0-255) kSuccess = 0, kOtherError = 1, kBadInput = 2, kOutOfMemory = 16, kOutOfDisk = 17, kAssertError = 70, kHttpOtherClientError = 80, kHttpCantConnectError = 81, kHttpNotFound = 66, // NotFound(404) kHttpUnauthorized = 77, // Unauthorized(401), kHttpSLLError = 82, kHttpForbidden = 83, // Forbidden(403) kHttpTimeout = 84, // RequestTimeout(408) kHttpConflict = 85, // Conflict(409) kHttpNoHost = 86, kHttpOtherServerError = 90, kHttpInternalServerError = 91, // InternalServerError(500) kHttpServiceUnavailable = 69, // ServiceUnavailable(503) kHttpBadGateway = 92, // BadGateway(502) kHttpGatewayTimeout = 93, // GatewayTimeout(504)
* improve console output (#476)Dan Engelbrecht2025-08-261-1/+1
| | | | * add color coded logging level to console output (for warn/err/crit levels) * clean up console output
* long filename support (#330)Dan Engelbrecht2025-03-311-1/+1
| | | - Bugfix: Long file paths now works correctly on Windows
* move basicfile.h/cpp -> zencore (#273)Dan Engelbrecht2025-01-161-1/+1
| | | | | | move jupiter.h/cpp -> zenutil move packageformat.h/.cpp -> zenhttp zenutil now depends on zenhttp instead of the inverse
* separate RPC processing from HTTP processing (#626)Stefan Boberg2023-12-201-1/+1
| | | | | | * moved all RPC processing from HttpStructuredCacheService into separate CacheRpcHandler class in zenstore * move package marshaling to zenutil. was previously in zenhttp/httpshared but it's useful in other contexts as well where we don't want to depend on zenhttp * introduced UpstreamCacheClient, this provides a subset of functions on UpstreamCache and lives in zenstore
* fixed v2 rpc recording issue with >4GB data per segment (#612)Stefan Boberg2023-12-151-114/+120
| | | | | | | | | * fixed v2 rpc recording issue with >4GB data per segment * implemented recovery logic to deal with partial RPC recordings * added check for invalid/null requests in RPC replay * also made sure at least one worker thread is configured * fix problem where "null" requests would cause infinite loop! * added basic RPC recorder tests
* moved process handling code into separate h/cpp (#555)Stefan Boberg2023-11-201-0/+1

* added missing includes (#504)Stefan Boberg2023-10-271-0/+1
| | | | | this change adds some includes to files which "inherit" includes from elsewhere this was exposed on another branch when removing some heavy dependencies from central headers
* Cache (rpc) activitity recording improvements (#482)Stefan Boberg2023-10-201-42/+81
| | | | | | | this adds a new RPC recording path aimed at more continuous recording and analysis of recorded sessions the new strategy is implemented alongside the original in order to retain the ability to read the older format the main difference between v2 and v1 is that the new strategy splits the recording into segments which are independent from each other. This is done to enable long running sessions with automatic disk cleanup (not implemented yet), appending to an existing recording (not implemented) and/or partial analysis and processing. The recorder will start a new segment when some criteria is fulfilled, including the number of files in the segment directory, disk footprint etc
* Collect all zen admin-related commands into admin.h/.cpp (#418)Dan Engelbrecht2023-09-221-0/+438
* move commands in scrub.h/cpp to admin_cmd.h/cpp * move job command into admin_cmd.h/.cpp * admin -> admin_cmd * bench -> bench_cmd * cache -> cache_cmd * copy -> copy_cmd * dedup -> dedup_cmd * hash -> hash_cmd * print -> print_cmd * projectstore -> projectstore_cmd * rpcreplay -> rpcreplay_cmd * serve -> serve_cmd * status -> status_cmd * top -> top_cmd * trace -> trace_cmd * up -> up_cmd * version -> version_cmd
