Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

127-127: 建议:添加日志记录

为了更好地追踪后台保存操作,建议在设置 is_bgsaving_ 标志时添加日志记录。

void PikiwiDB::StartBgsave() { 
  is_bgsaving_ = true; 
  INFO("Background saving started");
}

129-132: 建议:添加日志记录

为了更好地追踪后台保存操作,建议在重置 is_bgsaving_ 标志和更新 lastsave_ 时间戳时添加日志记录。

void PikiwiDB::FinishBgsave() {
  is_bgsaving_ = false;
  lastsave_ = pstd::UnixTimestamp();
  INFO("Background saving finished at {}", lastsave_);
}

819-839: 测试用例通过,但建议添加更多边缘情况。

该测试用例验证了写操作后的数据库大小一致性,结构良好。

建议添加更多边缘情况,例如在数据库中已有多个键值对的情况下测试数据库大小的一致性。

+		{
+			// 添加多个键值对
+			for i := 0; i < 10; i++ {
+				_, err := leader.Set(ctx, testKey+strconv.Itoa(i), testValue, 0).Result()
+				Expect(err).NotTo(HaveOccurred())
+			}
+
+			// 检查数据库大小
+			dbSize, err := leader.DBSize(ctx).Result()
+			Expect(err).NotTo(HaveOccurred())
+			Expect(dbSize).To(Equal(int64(11)))
+
+			// 读取检查
+			readChecker(func(c *redis.Client) {
+				dbSize, err := c.DBSize(ctx).Result()
+				Expect(err).NotTo(HaveOccurred())
+				Expect(dbSize).To(Equal(int64(11)))
+			})
+		}
