Version 0.18.5

Bug Fixes

lager debug ... flash and ... erase no longer fail with a 500 (filedescriptor out of range in select()) on a Lager Box that has been running for a long time. The box debug service is a long-lived process. Its GDB controller helper rebuilds a fresh gdb-multiarch connection on every retry attempt — retries that happen routinely while a debugger connection is coming up during flash and RTT — but a failed attempt was never registered for cleanup, so each one leaked the gdb-multiarch subprocess and the pipe handles to it. After enough leaks the service crossed the operating system’s 1024 file-descriptor limit for select(), at which point the tool that performs erase and flash crashed instead of running. Failed attempts are now closed immediately, and the erase/flash path uses poll() instead of select() so it is no longer bound by the 1024 limit even if descriptors run high. Recovering a box that has already hit this no longer needs anything beyond restarting the debug service.
