Use more descriptive error codes for specific failure scenarios___ **Consider using a more specific error code thankErrOther for uninitialized PRAFT and non-leader scenarios to improve error handling and client debugging.** [src/base_cmd.cc [41-46]](https://github.com/OpenAtomFoundation/pikiwidb/pull/316/files#diff-23c5847b03356e8dd665fe88eaea18e5a2ba197586895ecc56426ea9186f7fafR41-R46) ```diff -return client->SetRes(CmdRes::kErrOther, "PRAFT is not initialized"); -return client->SetRes(CmdRes::kErrOther, fmt::format("MOVED {}", PRAFT.GetLeaderAddress())); +return client->SetRes(CmdRes::kErrPraftUninitialized, "PRAFT is not initialized"); +return client->SetRes(CmdRes::kErrNotLeader, fmt::format("MOVED {}", PRAFT.GetLeaderAddress())); ``` Suggestion importance[1-10]: 8Why: Using more descriptive error codes enhances error handling and client debugging, making it easier to diagnose specific issues. | 8 |

4 months ago | ⏱️ Estimated effort to review [1-5] | 3, because the PR involves changes in the core command execution logic and introduces new conditions based on the state of the Raft cluster. Understanding the implications of these changes on the overall system behavior and ensuring they do not introduce new bugs or regressions requires a moderate level of effort. |
| 🧪 Relevant tests | Yes |
| ⚡ Possible issues | Possible Bug: The new code in `BaseCmd::Execute` does not handle the case where a command is neither read-only nor write, which might lead to unexpected behaviors for such commands. |
| 🔒 Security concerns | No |
| relevant file | src/base_cmd.cc |
| suggestion | Consider adding an else clause to handle commands that do not fall into read-only or write categories. This will ensure that all command types are accounted for and handled appropriately. [important] |
| relevant line | return client->SetRes(CmdRes::kErrOther, fmt::format("MOVED {}", PRAFT.GetLeaderAddress())); |

4 months ago 本次更改主要集中在对命令处理和测试逻辑的增强。包括在执行命令前检查PRAFT初始化和领导状态的逻辑修改，以及更新命令构造函数的参数以调整其行为。此外，还增强了数据库刷新测试中的错误检查逻辑。
| 文件路径 | 更改摘要 |
|---|---|
src/base_cmd.cc |
增加PRAFT初始化和领导状态检查逻辑。 |
src/cmd_admin.cc 和 src/cmd_kv.cc |
修改命令构造函数的参数，调整其行为和ACL类别。 |
tests/consistency_test.go |
增强数据库刷新测试中的错误检查逻辑。 |
代码变更如微风， 优雅修复，步步成。 测试更严代码精， PRAFT助力稳如松。 未来之路皆光明， 齐心协力，共锦绣。

read/write commands are now dropped if raft has not been initialized in raft mode, and an error message 'NOCLUSTER No Raft Cluster' is returned to the client. This change prevents the system from crashing due to failed assertions.
