Esteemed monks,
the gdb debugger can connect to any running process, perl scripts included. So if I know that my script has process id 1234, I can simply call
gdb -p 1234
and boom! I'm connected to the script. But can I also figure out which file and which line the script is currently processing? Typing
where shows a stack trace:
(gdb) where
#0 0x55000402 in ?? ()
#1 0x00c75420 in __nanosleep_nocancel () from /lib/tls/libc.so.6
#2 0x00c7526f in sleep () from /lib/tls/libc.so.6
#3 0x080dacea in Perl_pp_sleep ()
#4 0x080a6044 in Perl_runops_standard ()
#5 0x0806103e in S_run_body ()
#6 0x08060e36 in perl_run ()
#7 0x0805e359 in main ()
Does anyone know enough about
perlguts to figure out from here where (file/line) the script is right now?
