# Restart the local pxpipe proxy.
|
|
#
|
|
# What this does, in order:
|
|
# 1. Discover every running pxpipe proxy via `pgrep -f "node.*bin/cli.js"`
|
|
# and list them. If multiple are running (orphans from a prior crashed
|
|
# session), kill all of them — there's no "right" oldest in a graceful
|
|
# restart, we want a clean slate.
|
|
# 2. Send SIGTERM. The proxy's SIGTERM handler flushes the JSONL tracker
|
|
# and exits. Poll up to 5s for clean exit.
|
|
# 3. Anything still alive after 5s gets SIGKILL with a warning.
|
|
# 4. Rebuild (`pnpm run build`) unless --no-build is passed. Build errors
|
|
# abort the restart so we never start a stale binary.
|
|
# 5. Check the target port is actually free; if not, name the process
|
|
# holding it (with a hint for the user — common cause: another tool, or
|
|
# step 3 didn't fully release).
|
|
# 6. Start a fresh proxy via `exec node bin/cli.js "$@"` so Ctrl-C reaches
|
|
# Node directly.
|
|
#
|
|
# Flags:
|
|
# --no-build Skip the rebuild step. Use when you know dist/ is fresh.
|
|
#
|
|
# Examples:
|
|
# pnpm run restart
|
|
# pnpm run restart -- --no-build
|
|
# PORT=47899 pnpm run restart
|
