Use IntelliJ idea to debug PHP using X-debug, the main need to configure the section has three places, respectively, the configuration of php.ini , the configuration of idea and browser configuration, mainly as follows:The main configuration of php.ini (Wamp modified Phpforapache.ini) is as follows, and the key parameters can be modified according to the actual situation:xdebug:https://xdebug.org/download.p

When releasing a website, set debug to false and release debug to false. Under the root directory of the ASP.

After deploying a website on the server, you mustdebugSet to false as follows: If you wantdebugThe property value is false and must bemachine.config. The 32-bit computer machine. config is locat

Debug the dependency attribute of WPF by Windbg, and debug wpf by windbgWhen we use wndbg for debugging, we often need to view the dependency attribute values of a control.For example, we can view the Content dependency attribute of the DataGridColumnHeader.1. The windbg commands we use include :! Do ,! Da-details,. formats2. Use it! Do: view the member variables of the dependent object and find the specifi

JNI Layer Debug Thread crash reasonOne, causing the crash reason:In the thread function of the JNI layer, as long as the function called Env is added, it freezes two, the solution first we should understand: ① (Independence) jnienv is a thread-related variable, that is, thread A has a jnienv variable, thread B also has a jnienv variable, because thread-related, so a A thread cannot use the jnienv struct variable of a B thread.So how do you ensure the

Use GDB to debug programs and gdb to debug programs GDB (GNU Debuger) is a powerful Debugger in Linux. GDB allows you to view the internal structure of the program, print the variable value, set the breakpoint, debug the source code in a single step, modify the variable value during running, track the path, switch the thread, and display the assembly code.Compil

Debug stored procedures and oracle debug stored proceduresProblem background N lines of code are written in the stored procedure. As soon as the result is run, an error is reported in the database. So how can we immediately test the village crude process after writing the stored procedure?

When we learned the TFTLCD display after a very obvious problem is: parameter estimation is not accurate, for example, we want to draw a circle in the center of the screen, but often the coordinates are not allowed to lead to the MCU inside the burning process once, once a tune, but did not burn a burning can MCU life ah. Obviously this is very wasteful, so the good people think of a way (Orz), I am using the atom write Usmart component, the component porting is very simple, just need to pull th

Simple Guide for using PDB to debug Python programs, and a simple guide for using pdb to debug python In Python, you can also debug programs like gcc/gdb, as long as you introduce the pdb module when running the Python Program (assuming the program to be debugged is named d. py ):Copy codeThe Code is as follows:$ Vi d. py#! /Usr/bin/python Def main ():I, sum = 1,

Here we need to modify Python's processing flow after the exception occurs Sys.excepthook is the exception handler for the Python system, overrides a custom processor, and starts the PDB after printing the exception information.ImportSYSdefinfo (type, value, TB):#Exception Type #Exception Value #Call Stack ifHasattr (SYS,'PS1')or notSys.stderr.isatty ():#we're in interactive mode or we don't have a tty-like #device, so we call the default hookSys.__excepthook__(type, value, TB)E

The most basic operations are:1, first set a breakpoint in a Java file, and then run, when the program goes to the breakpoint will go to the debug view,2, F5 keys and F6 keys are single-step debugging, F5 is step into, that is, into the bank code execution, F6 is step over,That is, execute our code, jump to the next line,3,f7 is the bounce function .4,f8 is executed to the last. 1.Step into (also F5) jump2.Step over (also F6) skip3.Step return (also F
