fix(plugin): 7z 加密压缩改成参数列表调用，依赖预检先过 kwargs 校验

[yifenliwu]

接着 #579 的 review 收尾。那两条 CodeRabbit 意见当时没人回（PR 已经合了，行内也回不了），代码在 dev 上还是原样，所以另开一个 PR。

zip_with_password 在拼 shell 命令串

save_dir / zip_path / zip_password 都来自 option 配置，原来这么拼：

cmd_list = f'''
cd {self.save_dir}
7z a "{zip_path}" {file_args} -p{self.zip_password} -mhe=on > "../7z_output.txt"
'''
self.execute_multi_line_cmd(cmd_list)   # subprocess.run(cmd, shell=True, check=True)

shlex.quote 只包了文件名，另外三个值是裸拼进去的。密码里放个分号就能跑出去，跑一下当前代码看到的就是：

7z a "...\o.7z" a.csv -pp w; rm -rf / # -mhe=on > "../7z_output.txt"

-pp w 之后整串都被 shell 当成新命令了。

改成参数列表加 cwd=save_dir，不走 shell：

cmd = ['7z', 'a', zip_path]
cmd += [of_file_name(f) for f in files]
cmd += [f'-p{self.zip_password}', '-mhe=on']
with open(os.path.join(self.save_dir, '..', '7z_output.txt'), 'w') as out:
    subprocess.run(cmd, cwd=self.save_dir, stdout=out,
                   stderr=subprocess.STDOUT, check=True)

7z_output.txt 的位置和原来一致（还是在 save_dir 上一级）。密码里的空格、分号、引号现在都只是普通字符。

check_plugins_dependencies 没走 kwargs 校验

原来直接把 pinfo.get('kwargs') or {} 丢给 check_plugin_dependency。kwargs 写成真值标量（kwargs: enabled）时字符串被原样带下去，required_dependencies_for 里 kwargs.get(...) 就抛 AttributeError，把本该给出的「kwargs 必须为 dict」配置错误盖掉了。

改成先走一遍 self.fix_kwargs(...)，跟 invoke_plugin 用同一套校验，报错文案也就一致了。fix_kwargs 返回新 dict、不回写 pinfo，所以只是多解析一次，没有副作用。

测试

tests/test_jmcomic/test_jm_plugin.py 改了 2 条、加了 2 条。只把 src/jmcomic 回滚到改动前跑一遍：

3 failed, 1 passed, 11 deselected

改动全上之后 15 passed, 6 subtests passed。

base 取的是 dev 当前 HEAD。和 #580 没有重叠改动，不过两个 PR 都碰到 jm_plugin.py，先合一个再合另一个可能要 rebase，需要的话我来处理。

Summary by CodeRabbit

• Bug Fixes

  • Improved validation for plugin configuration values, providing a clearer error when kwargs is not a mapping.
  • Strengthened password-protected archive creation so passwords and file paths are handled safely, including passwords containing special characters.
  • Preserved safeguards against archiving the entire save directory and retained support for empty file lists.

• Tests

  • Added coverage for plugin configuration validation and secure archive command handling.

📝 Walkthrough

Walkthrough

The change validates plugin kwargs before dependency checks and replaces shell-based 7z command execution with argv-based subprocess execution. Tests cover invalid kwargs, empty archives, archive contents, and passwords containing shell metacharacters.

Changes

Plugin safety updates

Layer / File(s)	Summary
Plugin kwargs validation src/jmcomic/jm_option.py, tests/test_jmcomic/test_jm_plugin.py	Plugin kwargs pass through fix_kwargs. Non-mapping values now raise a readable JmcomicException.
Password-protected archive execution src/jmcomic/jm_plugin.py, tests/test_jmcomic/test_jm_plugin.py	The plugin calls 7z with an argv list, sets cwd to the save directory, redirects output through a file handle, and preserves the empty-file early return. Tests verify archive arguments and literal password handling.

Sensitive Data Exposure

Redact zip_password before logging.

cmd includes -p{self.zip_password}, and self.log forwards it unchanged to jm_log. The default logger writes messages to stdout, so the archive password is exposed to log readers. Keep cmd for subprocess.run and log a redacted copy.

Proposed fix

-        self.log(f'运行命令: {cmd}')
+        log_cmd = [*cmd[:-2], '-p***', cmd[-1]]
+        self.log(f'运行命令: {log_cmd}')
