deepin pr auto review

我来审查这段代码的修改,并提供改进意见:

语法逻辑

  1. 代码将 QSet<QString> 改为了 QStringList,并添加了 removeDuplicates() 调用来去除重复项。这从功能上来说是可行的,但可能不是最优的实现方式。

代码质量

  1. 使用 QStringList 而不是 QSet<QString> 来存储注解会降低查找效率。QSet 是基于哈希集合实现的,查找操作的时间复杂度是 O(1),而 QStringList 的查找是 O(n)。
  2. 代码中使用了 for (int i(0); i != method.outputArgs.size(); ++i) 这样的循环,虽然语法正确,但使用基于范围的 for 循环会更清晰。
  3. 注解的处理逻辑分散在代码中,可以考虑封装成一个单独的函数来提高可读性和可维护性。

代码性能

  1. QSet<QString> 改为 QStringList 并调用 removeDuplicates() 会导致性能下降:
    • QSet 自动保证元素的唯一性,不需要额外的去重操作
    • removeDuplicates() 需要遍历整个列表,时间复杂度为 O(n)
    • 后续的查找操作也会变慢

代码安全

  1. 代码中没有明显的安全问题,但可以考虑添加一些边界检查,比如确保 annotation 不为空。

改进建议

  1. 建议保持使用 QSet<QString>,因为它更适合存储唯一元素且性能更好:
QSet<QString> annotations;
for (const QDBusIntrospection::Interface *interface : interfaces) {
    for (const auto &method : interface->methods) {
        for (const auto &arg : method.outputArgs) {
            annotations += arg.annotations;
        }
        for (const auto &arg : method.inputArgs) {
            annotations += arg.annotations;
        }
    }
}
  1. 如果确实需要保持顺序,可以考虑使用 QSet 来检查重复项,同时维护一个 QStringList
QSet<QString> annotationSet;
QStringList annotationList;
for (const QDBusIntrospection::Interface *interface : interfaces) {
    for (const auto &method : interface->methods) {
        for (const auto &arg : method.outputArgs) {
            for (const QString &annotation : arg.annotations) {
                if (!annotationSet.contains(annotation)) {
                    annotationSet.insert(annotation);
                    annotationList.append(annotation);
                }
            }
        }
        // 类似处理 inputArgs
    }
}
  1. 将注解处理逻辑封装成单独的函数:
static QStringList collectAnnotations(const QList<QDBusIntrospection::Interface *> &interfaces)
{
    QSet<QString> annotations;
    for (const QDBusIntrospection::Interface *interface : interfaces) {
        for (const auto &method : interface->methods) {
            for (const auto &arg : method.outputArgs) {
                annotations += arg.annotations;
            }
            for (const auto &arg : method.inputArgs) {
                annotations += arg.annotations;
            }
        }
    }
    return annotations.values();
}

总结来说,原代码的修改虽然功能正确,但降低了代码的性能和效率。建议保持使用 QSet<QString> 来存储注解,这样可以获得更好的性能和更简洁的代码。
