// Argument parsing + usage for the daemon-relocation spike.
|
|
//
|
|
// The spike answers an empirical question (see README): what is the MINIMAL
|
|
// set of files that must be copied out of a packaged win-unpacked build so a
|
|
// COPIED Orca.exe (ELECTRON_RUN_AS_NODE=1) can host the terminal daemon and a
|
|
// real ConPTY session while holding no open handles into the install dir.

const USAGE = `
|
|
daemon-relocation-spike — minimal relocated daemon-host file-set probe (Windows)
|
|
|
|
Usage:
|
|
node tools/daemon-relocation-spike/spike.mjs --app-dir <win-unpacked> --work-dir <temp out> [--tier <t>]
|
|
node tools/daemon-relocation-spike/spike.mjs --selftest
|
|
|
|
Required (launch mode):
|
|
--app-dir <path> Path to a packaged win-unpacked build (contains Orca.exe)
|
|
--work-dir <path> Scratch dir for the copied host + logs (created, then removed)
|
|
|
|
Options:
|
|
--tier <t> File-set tier to copy: "full" (default), "no-gpu", "minimal"
|
|
full = Orca.exe + icudtl.dat + both snapshot blobs +
|
|
ALL top-level *.dll + daemon bundle + node-pty
|
|
no-gpu = full minus GPU/render DLLs (libEGL, libGLESv2,
|
|
vk_swiftshader, vulkan-1, d3dcompiler_47);
|
|
ffmpeg.dll kept
|
|
minimal = Orca.exe + icudtl.dat + both snapshots +
|
|
daemon bundle + node-pty only (no top-level DLLs)
|
|
--keep-work-dir Leave --work-dir on disk after the run (for inspection)
|
|
--selftest Validate arg parsing, tier defs, and the module-path filter
|
|
against synthetic inputs. No real build or launch. Exits
|
|
0 on pass, non-zero on failure.
|
|
-h, --help Show this help
|
|
|
|
Exit code is 0 only when the run PASSES: daemon ready, PTY echo round-trips the
|
|
nonce, and NO loaded module resolves under --app-dir.
