linux - Which line the program running on with a backtrace info? -


there backtrace info:

======= backtrace: ========= /lib64/libc.so.6(+0x7bc07)[0x7f959bba4c07] /lib64/libc.so.6(+0x7d23a)[0x7f959bba623a] /lib64/libspice-server.so.1(+0x2108e)[0x7f959c8d508e] /lib64/libspice-server.so.1(+0x227a3)[0x7f959c8d67a3] /usr/libexec/qemu-kvm(qemu_iohandler_poll+0xc6)[0x7f95a10571e6] /usr/libexec/qemu-kvm(main_loop_wait+0x188)[0x7f95a105b748] /usr/libexec/qemu-kvm(main+0x1240)[0x7f95a0f7ce30] /lib64/libc.so.6(__libc_start_main+0xf5)[0x7f959bb4aaf5] /usr/libexec/qemu-kvm(+0xb2ced)[0x7f95a0f80ced]

i create kvm instance spice, crashed , got message log.

now, want know line did make crash. no link symbol table /lib64/libspice-server.so.1.

i can address offset +0x2108e. way find out line did crash?

btw, tutorial debug library?

thanks.

any way find out line did crash?

your libc.so.6 , libspice-server.so.1 (apparently) fully-stripped.

you'll want install debuginfo packages both libraries, , use addr2line translate addresses symbol/file/line, so:

addr2line -fe /lib64/libc.so.6 0x7bc07 0x7d23a

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
