* zen history command (#987)Dan Engelbrecht2026-04-201-5/+6
| | | | | | | | | - Feature: Per-user invocation history for `zen` and `zenserver`; each startup appends a record to a JSONL file capped at the most recent 100 entries. Location: `%LOCALAPPDATA%\Epic\Zen\History\invocations.jsonl` on Windows, `~/.zen/History/invocations.jsonl` on POSIX - `zen history` opens an interactive picker; selecting a zen row re-runs it inline and forwards the exit code, selecting a zenserver row spawns it detached - `zen history --list` (`-l`) prints the table to stdout instead of showing the picker - `zen history --filter zen|zenserver` restricts the listing to one executable - `zen history --print` prints the reconstructed command line of the selected row instead of launching it - `--enable-execution-history` global option on both binaries (default `true`) to opt out per invocation - The history file is attached to Sentry crash reports (alongside the existing zenserver log)

* zen hub command (#877)Dan Engelbrecht2026-03-211-156/+19
| | | | | | | | | | | | | | | - Feature: Added `zen hub` command for managing a hub server and its provisioned module instances: - `zen hub up` - Start a hub server (equivalent to `zen up` in hub mode) - `zen hub down` - Shut down a hub server - `zen hub provision <moduleid>` - Provision a storage server instance for a module - `zen hub deprovision <moduleid>` - Deprovision a storage server instance - `zen hub hibernate <moduleid>` - Hibernate a provisioned instance (shut down, data preserved) - `zen hub wake <moduleid>` - Wake a hibernated instance - `zen hub status [moduleid]` - Show state of all instances or a specific module - Feature: Added new hub HTTP endpoints for instance lifecycle management: - `POST /hub/modules/{moduleid}/hibernate` - Hibernate the instance for the given module - `POST /hub/modules/{moduleid}/wake` - Wake a hibernated instance for the given module - Improvement: `zen up` refactored to use shared `StartupZenServer`/`ShutdownZenServer` helpers (also used by `zen hub up`/`zen hub down`) - Bugfix: Fixed shutdown event not being cleared after the server process exits in `ZenServerInstance::Shutdown()`, which could cause stale state on reuse
* Transparent proxy mode (#823)Stefan Boberg2026-03-121-67/+117
| | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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)

| | | | | - Feature: `zen builds pause`, `zen builds resume` and `zen builds abort` commands to control a running `zen builds` command - `--process-id` the process id to control, if omitted it tries to find a running process using the same executable as itself - Improvement: Process report now indicates if it is pausing or aborting

* zen startup hardening (#49)Dan Engelbrecht2024-04-171-42/+106
| | | | | | | | | | | | | - Feature: `zen up` command improvements - --`port` allows you to specify a base port when starting an instance - --`base-dir` allows you to specify a base directory for the zenserver executable if it is not located next to the zen.exe executable - Feature: `zen down` - --`port` allows you to specify a base port when shutting down an instance - --`base-dir` allows you to specify a base directory for the zenserver executable if it is not located next to the zen.exe executable - --`force` if regular shutdown fails it tries to find a running zenserver.exe process and terminate it - If it fails to attach to the running server it now waits for it to exit when setting the RequestExit shared memory flag - Improvement: zenserver now checks the RequestExit flag in the shared memory and exist gracefully if it is set - Improvement: When adding a sponsor process to a running zenserver instance, we wait for it to be picked up from the shared memory section to determine success/fail
