* Tui picker fixes (#1027)Stefan Boberg2026-05-041-71/+341
| | | | | | | | | | - **Viewport scrolling.** Cap rendered rows to the visible terminal height and track a scroll offset that follows the selection, so long lists no longer overflow the screen and corrupt the cursor-up redraw. Hint shows `[i/N]` when the list exceeds the viewport. - **Single-write frame rendering.** Each frame is built into one `ExtendableStringBuilder` and emitted via `TuiWrite`. On Windows, `TuiWrite` routes through `WriteConsoleW` when stdout is a console, so a frame is one syscall instead of one per `printf` — eliminates the visible per-character repaint. - **All `consoletui` helpers go through `TuiWrite`.** `TuiCursorHome`, `TuiSetScrollRegion`, `TuiResetScrollRegion`, `TuiMoveCursor`, `TuiSaveCursor`, `TuiRestoreCursor`, `TuiEraseLine`, `TuiShowCursor`, and the alternate-screen enter/exit pair now bypass the CRT on Windows consoles, matching the picker. `TuiFlush` remains an unconditional `fflush(stdout)` so callers that mixed `printf` output earlier in a sequence still drain correctly. - **Width detection fix.** `TuiConsoleColumns` now reports the visible window width rather than the screen-buffer width, so labels sized to it don't wrap on legacy cmd.exe configs where the buffer is wider than the window. - **PgUp / PgDn.** Jump by one viewport, clamped to the list ends. `VK_PRIOR` / `VK_NEXT` on Windows; `ESC[5~` / `ESC[6~` on POSIX. - **Terminal resize handling.** Enable `ENABLE_WINDOW_INPUT` on stdin (Windows) and install a `SIGWINCH` handler without `SA_RESTART` (POSIX) so the blocking key read returns a new `ConsoleKey::Resize`. The picker recomputes viewport/label budgets, clears the visible screen, and redraws as a fresh first frame; pre-picker output stays in scrollback. - **Centralized label truncation.** The picker truncates item labels to fit the current terminal width (cols minus the 3-column indicator), walking back to a UTF-8 codepoint boundary so multi-byte sequences are never split. The hand-rolled width-aware truncation in `history_cmd::BuildLabel` and `ui_cmd` is removed; callers hand the picker the full label and let it clip.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ### Compute Batch Submission - Consolidate duplicated action submission logic in `httpcomputeservice` into a single `HandleSubmitAction` supporting both single-action and batch (actions array) payloads - Group actions by queue in `RemoteHttpRunner` and submit as batches with configurable chunk size, falling back to individual submission on failure - Extract shared helpers: `MakeErrorResult`, `ValidateQueueForEnqueue`, `ActivateActionInQueue`, `RemoveActionFromActiveMaps` ### Retracted Action State - Add `Retracted` state to `RunnerAction` for retry-free rescheduling — an explicit request to pull an action back and reschedule it on a different runner without incrementing `RetryCount` - Implement idempotent `RetractAction()` on `RunnerAction` and `ComputeServiceSession` - Add `POST jobs/{lsn}/retract` and `queues/{queueref}/jobs/{lsn}/retract` HTTP endpoints - Add state machine documentation and per-state comments to `RunnerAction` ### Compute Race Fixes - Fix race in `HandleActionUpdates` where actions enqueued between session abandon and scheduler tick were never abandoned, causing `GetActionResult` to return 202 indefinitely - Fix queue `ActiveCount` race where `NotifyQueueActionComplete` was called after releasing `m_ResultsLock`, allowing callers to observe stale counters immediately after `GetActionResult` returned OK ### Logging Optimization and ANSI improvements - Improve `AnsiColorStdoutSink` write efficiency — single write call, dirty-flag flush, `RwLock` instead of `std::mutex` - Move ANSI color emission from sink into formatters via `Formatter::SetColorEnabled()`; remove `ColorRangeStart`/`End` from `LogMessage` - Extract color helpers (`AnsiColorForLevel`, `StripAnsiSgrSequences`) into `helpers.h` - Strip upstream ANSI SGR escapes in non-color output mode. This enables colour in log messages without polluting log files with ANSI control sequences - Move `RotatingFileSink`, `JsonFormatter`, and `FullFormatter` from header-only to pimpl with `.cpp` files ### CLI / Exec Refactoring - Extract `ExecSessionRunner` class from ~920-line `ExecUsingSession` into focused methods and a `ExecSessionConfig` struct - Replace monolithic `ExecCommand` with subcommand-based architecture (`http`, `inproc`, `beacon`, `dump`, `buildlog`) - Allow parent options to appear after subcommand name by parsing subcommand args permissively and forwarding unmatched tokens to the parent parser ### Testing Improvements - Fix `--test-suite` filter being ignored due to accumulation with default wildcard filter - Add test suite banners to test listener output - Made `function.session.abandon_pending` test more robust ### Startup / Reliability Fixes - Fix silent exit when a second zenserver instance detects a port conflict — use `ZEN_CONSOLE_*` for log calls that precede `InitializeLogging()` - Fix two potential SIGSEGV paths during early startup: guard `sentry_options_new()` returning nullptr, and throw on `ZenServerState::Register()` returning nullptr instead of dereferencing - Fail on unrecognized zenserver `--mode` instead of silently defaulting to store ### Other - Show host details (hostname, platform, CPU count, memory) when discovering new compute workers - Move frontend `html.zip` from source tree into build directory - Add format specifications for Compact Binary and Compressed Buffer wire formats - Add `WriteCompactBinaryObject` to zencore - Extended `ConsoleTui` with additional functionality - Add `--vscode` option to `xmake sln` for clangd / `compile_commands.json` support - Disable compute/horde/nomad in release builds (not yet production-ready) - Disable unintended `ASIO_HAS_IO_URING` enablement - Fix crashpad patch missing leading whitespace - Clean up code triggering gcc false positives
* Add `zen ui` command (#779)Stefan Boberg2026-02-241-0/+483
Allows user to automate launching of zenserver dashboard, including when multiple instances are running. If multiple instances are running you can open all dashboards with `--all`, and also using the in-terminal chooser which also allows you to open a specific instance. Also includes a fix to `zen exec` when using offset/stride/limit
