ThinkPHP笔记——开启debug调试模式，thinkphpdebug
debug+trace模式可以查看开发过程中TP的错误信息，可以更好地帮助开发者debug。但是debug模式的开启还不是简单的在配置文件中中设置就可以的，经过查资料摸索，找到一种有效的方法。
首先在你已经部署好了ThinkPHP的项目目录
然后注意是在入口文件开启调试模式，在入口文件index.php 中写入一下代码define(‘APP_DEBUG’,true); 首先删除Runtime目录 ，然后再次运行一下，你会发现runtime目录下面的~runtime.php 文件没有了，说明你的调试模式开启成功了
之所以这个~runtime.php文件删除 ，这个文件是编译后的文件 会有缓存，所以在调试模式期间我们不用担心因为缓存而造成其他错误
trace页面的 也是我们开发者获取错误信息的而一个途径，所以我们需要开启trace页面，在THinkPHp3.0版本中trace页面是默认没有开启的，需要我们手动 的在项目配置文件中添加
‘SHOW_PAGE_TRACE’ =>true, // 显示页面Trace信息
想要看看trace信息是否开启了，只要我们在 IndexAction.class.php 中的index方
法中加上$this->display();
然后再次运行如果你看到了如下界面，说明你的调试模式，以及trace 以及开启了
你用dw什么的修改一个页面属性 看编缉一致不 一般是编码问题 所致
什么版本的thinkphp
现在都写在入口文件了
define('APP_DEBUG', true);
不贴源码，神也救不了你

Detailed explanation of C++ function debugging: How to debug problems in multi-threaded functions?
May 02, 2024 pm 04:15 PM
C++ multi-thread debugging can use GDB: 1. Enable debugging information compilation; 2. Set breakpoints; 3. Use infothreads to view threads; 4. Use thread to switch threads; 5. Use next, stepi, and locals to debug. Actual case debugging deadlock: 1. Use threadapplyallbt to print the stack; 2. Check the thread status; 3. Single-step the main thread; 4. Use condition variables to coordinate access to solve the deadlock.
How to use LeakSanitizer to debug C++ memory leaks?
Jun 02, 2024 pm 09:46 PM
How to use LeakSanitizer to debug C++ memory leaks? Install LeakSanitizer. Enable LeakSanitizer via compile flag. Run the application and analyze the LeakSanitizer report. Identify memory allocation types and allocation locations. Fix memory leaks and ensure all dynamically allocated memory is released.
Shortcut to golang function debugging and analysis
May 06, 2024 pm 10:42 PM
This article introduces shortcuts for Go function debugging and analysis, including: built-in debugger dlv, which is used to pause execution, check variables, and set breakpoints. Logging, use the log package to record messages and view them during debugging. The performance analysis tool pprof generates call graphs and analyzes performance, and uses gotoolpprof to analyze data. Practical case: Analyze memory leaks through pprof and generate a call graph to display the functions that cause leaks.
How to conduct concurrency testing and debugging in Java concurrent programming?
May 09, 2024 am 09:33 AM
Concurrency testing and debugging Concurrency testing and debugging in Java concurrent programming are crucial and the following techniques are available: Concurrency testing: Unit testing: Isolate and test a single concurrent task. Integration testing: testing the interaction between multiple concurrent tasks. Load testing: Evaluate an application's performance and scalability under heavy load. Concurrency Debugging: Breakpoints: Pause thread execution and inspect variables or execute code. Logging: Record thread events and status. Stack trace: Identify the source of the exception. Visualization tools: Monitor thread activity and resource usage.
How to debug PHP asynchronous code

Jun 05, 2024 pm 03:18 PM
Common PHP debugging errors include: Syntax errors: Check the code syntax to make sure there are no errors. Undefined variable: Before using a variable, make sure it is initialized and assigned a value. Missing semicolons: Add semicolons to all code blocks. Function is undefined: Check that the function name is spelled correctly and make sure the correct file or PHP extension is loaded.
Detailed explanation of C++ function debugging: How to debug problems in functions that contain exception handling?
Apr 30, 2024 pm 01:36 PM
C++ debugging functions that contain exception handling uses exception point breakpoints to identify exception locations. Use the catch command in gdb to print exception information and stack traces. Use the exception logger to capture and analyze exceptions, including messages, stack traces, and variable values.
