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.

Switches the default HTTP client to the libcurl-based backend and follows up with a series of correctness fixes and code quality improvements to `CurlHttpClient`.
**Backend switch & build fixes:**
- Switch default HTTP client to libcurl-based backend
- Suppress `[[nodiscard]]` warning when building fmt
- Miscellaneous bugfixes in HttpClient/libcurl
- Pass `-y` to `xmake config` in `xmake test` task
**Boilerplate reduction:**
- Add `Session::SetHeaders()` for RAII ownership of `curl_slist`, eliminating manual `curl_slist_free_all` calls from every verb method
- Add `Session::PerformWithResponseCallbacks()` to absorb the repeated 12-line write+header callback setup block
- Extract `ParseHeaderLine()` shared helper, replacing 4 duplicate header-parsing implementations
- Extract `BuildHeaderMap()` and `ApplyContentTypeFromHeaders()` helpers to deduplicate header-to-map conversion and Content-Type scanning
- Unify the two `DoWithRetry` overloads (PayloadFile variant now delegates to the Validate variant)
**Correctness fixes:**
- `TransactPackage`: both phases now use `PerformWithResponseCallbacks()`, fixing missing abort support and a dead header collection loop
- `TransactPackage`: error path now routes through `CommonResponse`, preserving curl error codes and messages for the caller
- `ValidatePayload`: merged 3 separate header-scan loops into a single pass
**Performance improvements:**
- Replace `fmt::format` with `ExtendableStringBuilder` in `BuildHeaderList` and `BuildUrlWithParameters`, eliminating heap allocations in the common case
- Replace `curl_easy_escape`/`curl_free` with inline URL percent-encoding using `AsciiSet`
- Remove wasteful `CommonResponse(...)` construction in retry logging, formatting directly from `CurlResult` fields

- Add `--no-network` CLI option which disables all TCP/HTTPS listeners, restricting zenserver to Unix domain socket communication only.
- Also fixes asio upgrade breakage on main

Adds a **transparent TCP proxy mode** to zenserver (activated via `zenserver proxy`), allowing it to sit between clients and upstream Zen servers to inspect and monitor HTTP/1.x traffic in real time. Primarily useful during development, to be able to observe multi-server/client interactions in one place.
- **Dedicated proxy port** -- Proxy mode defaults to port 8118 with its own data directory to avoid collisions with a normal zenserver instance.
- **TCP proxy core** (`src/zenserver/proxy/`) -- A new transparent TCP proxy that forwards connections to upstream targets, with support for both TCP/IP and Unix socket listeners. Multi-threaded I/O for connection handling. Supports Unix domain sockets for both upstream/downstream.
- **HTTP traffic inspection** -- Parses HTTP/1.x request/response streams inline to extract method, path, status, content length, and WebSocket upgrades without breaking the proxied data.
- **Proxy dashboard** -- A web UI showing live connection stats, per-target request counts, active connections, bytes transferred, and client IP/session ID rollups.
- **Server mode display** -- Dashboard banner now shows the running server mode (Zen Proxy, Zen Compute, etc.).
Supporting changes included in this branch:
- **Wildcard log level matching** -- Log levels can now be set per-category using wildcard patterns (e.g. `proxy.*=debug`).
- **`zen down --all`** -- New flag to shut down all running zenserver instances; also used by the new `xmake kill` task.
- Minor test stability fixes (flaky hash collisions, per-thread RNG seeds).
- Support ZEN_MALLOC environment variable for default allocator selection and switch default to rpmalloc
- Fixed sentry-native build to allow LTO on Windows

The main goal of this change is to eliminate the cpr back-end altogether and replace it with the curl implementation. I would expect to drop cpr as soon as we feel happy with the libcurl back-end. That would leave us with a direct dependency on libcurl only, and cpr can be eliminated as a dependency.
### HttpClient Backend Overhaul
- Implemented a new **libcurl-based HttpClient** backend (`httpclientcurl.cpp`, ~2000 lines)
as an alternative to the cpr-based one
- Made HttpClient backend **configurable at runtime** via constructor arguments
and `-httpclient=...` CLI option (for zen, zenserver, and tests)
- Extended HttpClient test suite to cover multipart/content-range scenarios
### Unix Domain Socket Support
- Added Unix domain socket support to **httpasio** (server side)
- Added Unix domain socket support to **HttpClient**
- Added Unix domain socket support to **HttpWsClient** (WebSocket client)
- Templatized `HttpServerConnectionT<SocketType>` and `WsAsioConnectionT<SocketType>`
to handle TCP, Unix, and SSL sockets uniformly via `if constexpr` dispatch
### HTTPS Support
- Added **preliminary HTTPS support to httpasio** (for Mac/Linux via OpenSSL)
- Added **basic HTTPS support for http.sys** (Windows)
- Implemented HTTPS test for httpasio
- Split `InitializeServer` into smaller sub-functions for http.sys
### Other Notable Changes
- Improved **zenhttp-test stability** with dynamic port allocation
- Enhanced port retry logic in http.sys (handles ERROR_ACCESS_DENIED)
- Fatal signal/exception handlers for backtrace generation in tests
- Added `zen bench http` subcommand to exercise network + HTTP client/server communication stack

- Feature: Added `--security-config-path` option to zenserver to configure security settings
- Expects a path to a .json file
- Default is an empty path resulting in no extra security settings and legacy behavior
- Current support is a top level filter of incoming http requests restricted to the `password` type
- `password` type will check the `Authorization` header and match it to the selected authorization strategy
- Currently the security settings is very basic and configured to a fixed username+password at startup
{
"http" {
"root": {
"filter": {
"type": "password",
"config": {
"password": {
"username": "<username>",
"password": "<password>"
},
"protect-machine-local-requests": false,
"unprotected-uris": [
"/health/",
"/health/info",
"/health/version"
]
}
}
}
}

This PR brings over some changes made to avoid performing setup for otel instrumentation if we are not sending otel information anywhere anyway.
It also adds the ability to configure an OTLP endpoint on the command line using `--otlp-endpoint=<URI>`.
Bear in mind that OTLP support is still not officially supported so this should not be used in production at this stage.

* make sure the correct `UE_WITH_TRACE` conditional is used to enable/disable support code as appropriate
* fixed some accidental `int32`, `int64` et al usage, due to typedefs leaking through from trace header
with this fix, it is now possible to build with `--zentrace=no` again

this breaks out the configuration logic to allow multiple applications to share common configuration and initialization logic whilst customizing chosen aspects of the process
|
|
|
* move all storage-related services into storage tree
* move config into config/
* also move admin service into storage since it mostly has storage related functionality
* header consolidation
