Improvement: rename the variables in TCP reconnect function and some default constants #84
Conversation
WalkthroughThe changes made across multiple files in the repository involve enhancements and adjustments to the TCP client connection management, specifically regarding the reconnection logic. This includes renaming and reorganizing constants, updating the reconnection function to use new parameters, adding support for maximum reconnect attempts, refining error handling for setting deadlines, and adjusting configuration and initialization to support these new options.

This function allows for setting the maximum number of reconnect attempts, which is a useful addition. However, consider checking for negative values as well to ensure robustness.

@AlexStocks 雨哥，看着 reconnect 那边的逻辑其实可以加个 issue，太多参数都是临时变量，不利于维护。其实变成 client 里面的参数会更好一点。 |

这个要不调小一点，看着是短时间内发起 100次重连请求。
我把里面的一些变量调整为短变量申明的方式，这样看上去可能会好一点。然后除了maxReconnectAttempts（这个参数是client-side需要关心的参数，其他都不需要放到client里） |
…, adjust the defaultMaxReconnectAttempts from 100 to 50, and add the client's specification of the maxReconnectAttempts in the unit test

Review of reConnect function modifications.
The renaming of parameters and the restructuring of the reconnect logic are consistent with the PR's objectives. However, the logic for calculating maxReconnectInterval could be simplified, and there's an inconsistency in the renaming (maxTimes was supposed to be defaultMaxReconnectAttempts but is changed to maxBackOffTimes).
- maxBackOffTimes = 10
+ defaultMaxReconnectAttempts = 10Additionally, consider simplifying the calculation of maxReconnectInterval to improve readability.
- if reconnectAttempts > maxBackOffTimes {
- maxReconnectInterval = int64(maxBackOffTimes) * int64(reconnectInterval)
- } else {
- maxReconnectInterval = int64(reconnectAttempts) * int64(reconnectInterval)
- }
+ maxReconnectInterval = int64(min(reconnectAttempts, maxBackOffTimes)) * int64(reconnectInterval)…d simplify the maxReconnectInterval calculation

Incomplete Renaming of Constants

Incomplete Variable Renaming
The variables num, times, and maxDuration have not been fully renamed to sessionNum, reconnectAttempts, and maxReconnectInterval respectively in the codebase. The following occurrences in transport/client.go still need to be updated:

Renamed Variables for Clarity.
The variables num, times, and maxDuration have been renamed to sessionNum, reconnectAttempts, and maxReconnectInterval respectively. Ensure that all references to these variables in the codebase are updated accordingly.
The search results indicate that the old variable names num, times, and maxDuration still exist in the codebase. This suggests that not all references have been updated. To verify this, we need to check the specific lines in transport/client.go and other related files to confirm whether the renaming was applied correctly.
