问题描述
有没有一种方法可以在不附加GDB的情况下打印所有线程的堆栈跟踪?
或者是否有一个命令可以用作gdb批处理模式打印所有线程的堆栈跟踪线程?
解决方案在GDB中有一个线程应用所有命令:
(gdb)线程全部应用bt 线程12(线程0x7f7fe2116700(LWP 5466)): #0 sem_wait()at ../nptl/sysdeps/unix/sysv/linux/x86_64/sem_wait.S:86 #1 0x0000000000425358 in ?? () ... 线程1(线程0x7f7feabc27c0(LWP 5465)):#0 0x00007f7fe76c5203在select()at ../sysdeps/unix/syscall-template.S:82不幸的是,GDB似乎无法从管道读取命令,因此要运行命令在批处理模式下,必须使用一个临时文件:
$ gdbbt(){ tmp = $(tempfile ) echo thread apply all bt>$ tmp gdb -batch -nx -q -x$ tmp-p$ 1 rm -f$ tmp} $ gdbbt $(pidof $ SHELL)
Is there a way to print stacktrace of all threads without attaching GDB?
Or is there a command which I can use as gdb batch mode to print stacktrace of all threads?
解决方案There is a thread apply all command in GDB:
(gdb) thread apply all bt Thread 12 (Thread 0x7f7fe2116700 (LWP 5466)): #0 sem_wait () at ../nptl/sysdeps/unix/sysv/linux/x86_64/sem_wait.S:86 #1 0x0000000000425358 in ?? () ... Thread 1 (Thread 0x7f7feabc27c0 (LWP 5465)): #0 0x00007f7fe76c5203 in select () at ../sysdeps/unix/syscall-template.S:82Sadly, GDB seems not to be able to read the commands from a pipe, so to run the commands in its batch mode, a temporary file must be used:
$ gdbbt() { tmp=$(tempfile) echo thread apply all bt >"$tmp" gdb -batch -nx -q -x "$tmp" -p "$1" rm -f "$tmp" } $ gdbbt $(pidof $SHELL)
