sl0pboy.git/core.3092236, branch master sl0pboy - a Game Boy Color emulator (companion to the gbos OS) https://git.sl0p.foo/sl0pboy.git/atom/core.3092236?h=master 2026-07-15T21:44:28Z serial: headless mode tying serial port to stdio for OS debugging 2026-07-15T21:44:28Z gbc dev gbc@localhost 2026-07-15T21:44:28Z urn:sha1:24a015ff047d4b7bb955ba4bc61d5793d7492878 - --headless: no rendering/TUI; serial TX -> stdout, RX <- stdin (nonblocking) - generalize serial: serial_out_fd/serial_in_fd on the GB; internal-clock transfer now shifts in a real RX byte (from stdin) instead of always 0xFF - paced to native speed by default, --uncapped for turbo; pipes/scripts cleanly - README: document headless serial console fix(control): ignore SIGPIPE so a vanishing client can't kill the emulator 2026-07-14T23:42:34Z gbc dev gbc@localhost 2026-07-14T23:42:34Z urn:sha1:2d39cb0b3ff9851e9872b3eb1f1324bde6910a1c A client that connects and closes before reading (e.g. the HUD's liveness probe) made the greeting write() raise SIGPIPE, terminating the whole emulator - this was behind much of the 'it keeps dying' this session. Also: gbhud now re-resolves the live instance from the registry on every reconnect (skipping stale sockets by test-connecting), so the HUD follows respawns, and its box rendering is ANSI-width-correct.
