mosdns 版本

v5.1.3-0-gac99eb1

操作系统

macOS Ventura 13.3.1

Bug 描述和复现步骤

从 main_sequence 进入 local_sequence 后，如果 has_resp 的话 accept。

按照文档 accept 后所有 sequence 都不再继续执行后续规则，但是日志打印显示还是回到 main_sequence 中继续执行了。

使用的配置文件

plugins:
  - tag: local_forward
    type: forward
    args:
      concurrent: 1
      upstreams:
        - addr: https://1.12.12.12/dns-query

  - tag: local_sequence
    type: sequence
    args:
      - exec: debug_print AAAAAAAAAAAAAAAAAAAA
      - exec: $local_forward
      - matches: has_resp
        exec: debug_print BBBBBBBBBBBBBBBBBBBB
      - matches: has_resp
        exec: accept

  - tag: main_sequence
    type: sequence
    args:
      - exec: prefer_ipv4
      - matches: qname &./Loyalsoldier/direct-list.txt
        exec: $local_sequence
      - exec: debug_print CCCCCCCCCCCCCCCCCCCC

  - tag:
    type: udp_server
    args:
      entry: main_sequence
      listen: :53

exec: $local_sequence 改为 exec: jump local_sequence 解决
