How to reproduce:
- Turn off networking on your computer.
- Eval this code in the repl:
(handler-case (usocket:get-hosts-by-name "github.com")
(USOCKET:NS-HOST-NOT-FOUND-ERROR (c)
(format nil "Slot bound: ~A"
(slot-boundp c 'usocket::host-or-ip))))It will output:
If you eval (usocket:get-hosts-by-name "github.com") then you'll see such traceback:
Condition USOCKET:NS-HOST-NOT-FOUND-ERROR was signalled.
[Condition of type USOCKET:NS-HOST-NOT-FOUND-ERROR]
Restarts:
0: [RETRY-REQUEST] Retry the same request.
1: [RETRY] Retry SLY mREPL evaluation request.
2: [*ABORT] Return to SLY's top level.
3: [ABORT] abort thread (#<THREAD "sly-channel-1-mrepl-remote-1" RUNNING {1003C8BFF3}>)
