fix #2446

改动如下:
1、一个 client watch 的 key,被任何人修改(包括自己的改动),都会失效;
2、当执行 flushdb、flushall 命令时,只有当 watch 的 key 的值非空,才会影响这个 watch 动作;
3、添加了 multi 命令的 ACL 测试

Walkthrough

The recent updates to the Pika system enhance transaction management by replacing the SetAllTxnFailed method with SetTxnFailedIfKeyExists, enabling conditional failure based on key existence. This change refines the control logic around transactions. Additionally, the test suite for MULTI and EXEC commands has been robustly updated to ensure improved handling and verification of transactional behavior.

Changes

Files Change Summary
include/pika_client_conn.h, Method signature changed from SetAllTxnFailed() to SetTxnFailedIfKeyExists(const std::string target_db_name = "").
src/pika_client_conn.cc Function renamed to allow for conditional key existence checks; enhanced transaction failure logic.
src/pika_transaction.cc Transaction failure handling updated to use key existence checks; key formatting modified in WatchCmd::DoInitial().
tests/unit/multi.tcl, New helper function added; tests revised for key naming conventions and transactional behavior, enhancing robustness and clarity.
tests/test_helper.tcl New redis_client procedure added; test organization improved with the introduction of a global variable for connection configuration.

Poem

🐇 In the realm where transactions flow,
A watchful eye on keys we bestow.
With every command, a dance we make,
Ensuring no errors, for clarity's sake.
So let us hop and celebrate this cheer,
For Pika's new steps bring us near! 🌼

Verification successful

The method SetTxnFailedIfKeyExists is implemented correctly.

The implementation of SetTxnFailedIfKeyExists in src/pika_client_conn.cc aligns with the new functionality specified in the method signature.

If a key exists, it sets the transaction watch state to failed.

190-190: Verify the impact of logging command names.

Ensure that the logging of command names does not introduce any performance issues.


397-425: Verify the functionality of the new logic in SetTxnFailedIfKeyExists.

Ensure that the new logic works correctly and handles all edge cases, including the iteration through watched database keys and the existence check in the specified target database.


193-195: Verify the functionality of the SetTxnFailedIfKeyExists function.

Ensure that the modified function works correctly and handles all edge cases, including the new target_db_name parameter.

Verification successful

The SetTxnFailedIfKeyExists function works correctly and handles the target_db_name parameter as intended.

  • The function correctly iterates through involved connections and sets the transaction to a failed state if the key exists in the specified target database.
  • The calls to this function in src/pika_transaction.cc and src/pika_client_conn.cc handle the parameter correctly.

Add error handling for redis_client creation and wait_for_condition execution.

The function wait_for_dbsize lacks error handling for the redis_client creation and the wait_for_condition execution. Consider adding error handling to make the function more robust.

proc wait_for_dbsize {size} {
    set r2 [redis_client]
    if {$r2 == ""} {
        fail "Failed to create redis client"

如果一个client watch 了一个 key,就算这个 key 是被这个 client 自己修改的,这个 watch 也会失效。redis 是这个逻辑,所以去除了和这个判断
