~/.lldbinit is loaded many times

[zchrissirhcz]

Hi, vscode-lldb Authors, Developers and Users:

I write a custom lldb formatter, and it seems loaded many times (I expect only load once).

Environment

CodeLLDB plugin version: 1.7.0 (Linux x64, Ubuntu 20.04)

Settings.json:

    "lldb.launch.initCommands": ["command source ${env:HOME}/.lldbinit"], // 加载用户的 ~/.lldbinit
    "lldb.verboseLogging" : true,

C++ code

Debugging with C/C++ code:

// https://github.com/intel/ARM_NEON_2_x86_SSE/blob/master/NEON_2_SSE.h
#include "NEON_2_SSE.h"
#include <stdio.h>

int main() {
    uint8_t w8u2[16] = {1, 2, 3, 4, 5, 6, 7, 8, 11, 12, 13, 14, 15, 16, 17, 18};
    uint8x16_t vw8u2 = vld1q_u8(w8u2);
    uint8_t buf2[16];

    vst1q_u8(buf2, vw8u2);
    printf("Done2\n"); // set a breakpoint here

    int8_t w8u3[16] = {-128, -127, 3, 4, 5, 6, 7, 8, 11, 12, 13, 14, 15, 16, 17, 18};
    int8x16_t vw8u3 = vld1q_s8(w8u3);
    int8_t buf3[16];
    vst1q_s8(buf3, vw8u3);
    printf("Done3\n"); // set a breakpoint here

    return 0;
}

LLDB config

The customed LLDB formatter: ~/.lldbcfg/dbg_print.py:

def print_int8x16_t(valobj, internal_dict):
    print(">>> print_int8x16_t")
    res = 'print_int8x16_t'
    return res

def print_uint8x16_t(valobj, internal_dict):
    print(">>> print_uint8x16_t")
    res = 'print_uint8x16_t'
    return res

def __lldb_init_module(debugger, internal_dict):
    debugger.HandleCommand('type summary add -C no -P int8x16_t -F {:s}.print_int8x16_t'.format(__name__))
    debugger.HandleCommand('type summary add -C no -P uint8x16_t -F {:s}.print_uint8x16_t'.format(__name__))

The ~/.lldbinit configuration file:

command script import ~/.lldbcfg/dbg_print.py

Output

The actual output:

The terminal output (Use CodeLLDB bundled lldb, but in a terminal, instead of VSCode):

Question

Question: I guess the ~/.lldbinit or ~/.lldbcfg/dbg_print.y script is loaded many times, and I expect it only be load once.
Is my Settings.json configured not correctly ? Or if this is a bug/feature of CodeLLDB ?
