IDA plugin handles signal only when I click the "hotkey" and not when I execute signal with
$ echo "test" > /tmp/fifo & # created w/ `mkfifo /tmp/fifo` $ kill -SUIGUSR2 $(pidof ida)
import idaapi import signal def receiveSignal(signalNumber, frame): print('Received:', signalNumber) print('[+]', open('/tmp/fifo').readline()) return class PluginEntry(idaapi.plugin_t): flags = 0 # load each time a database is opened in IDA. comment = "" help = "" wanted_name = "A" wanted_hotkey = "Alt+S" def init(self): signal.signal(signal.SIGUSR2, receiveSignal) return idaapi.PLUGIN_OK def term(self): pass def run(self, arg): print('[-] run') def PLUGIN_ENTRY(): return PluginEntry()
When I hit the hotkey;
[-] run Received: 12 [+] test
Is there a way to make it handle on signal ?
