To answer this for any particular case, one would need the launch.json configuration being used, and the source folder structure, at minimum. I have a true story from just last week to illustrate why: Background I recently inherited a relatively small Vue project, and immediately encountered the same problem. Breakpoints in VSCode were “jumpy” in … Read more
Error and console.log surprises When trying to use console.log to view an error, you might be surprised to not see all the error data available. This is because console.log treats values which are instances of the built-in Error class in a special way, printing only the message, the type, and the stack. Apollo extends its … Read more
ESP is the current stack pointer. EBP is the base pointer for the current stack frame. When you call a function, typically space is reserved on the stack for local variables. This space is usually referenced via EBP (all local variables and function parameters are a known constant offset from this register for the duration … Read more
Compiler does not need to “modify” the binary in any way to support the breakpoints. However it is important, that: Compiler includes enough information in the executable (that is not in the code itself but in special sections in same file), so that debugger can relate source that user wants to debug with machine code. … Read more
This page shows some general techniques. In short, run with enabled assertions (-ea JVM flag). kotlinx-coroutines-debug module is specifically designed for what its name says. This is how I use it in unit tests; runBlocking { DebugProbes.install() val deferred = async { methodUnderTest() } delay(3000) DebugProbes.dumpCoroutines() println(“\nDumping only deferred”) DebugProbes.printJob(deferred) DebugProbes.uninstall() cleanup() } There’s a … Read more
The following code works for me curl -i -X POST -d ‘{“some”:”data”}’ http://your-local-domain -b XDEBUG_SESSION=PHPSTORM
I believe you’re looking for: info symbol <addresss> Print the name of a symbol which is stored at the address addr. If no symbol is stored exactly at addr, GDB prints the nearest symbol and an offset from it. Example: (gdb) info symbol 0x400225 _start + 5 in section .text of /tmp/a.out (gdb) info symbol … Read more
Firstly, the level name to use is FINE, not DEBUG. Let’s assume for a minute that DEBUG is actually valid, as it makes the following explanation make a bit more sense… In the Handler specific properties section, you’re setting the logging level for those handlers to DEBUG. This means the handlers will handle any log … Read more
I don’t know that there is an option to create a watch expression directly from Xcode 4’s code window. If there’s something in the code window you’ll want to add an expression watch for, I think you’ll have to copy that code to the clipboard. Then while debugging, make sure the debug area is being … Read more
Qt defines QT_NO_DEBUG for release builds. Otherwise QT_DEBUG is defined. Of course you are free to specify any DEFINES in your .pro files and scope them for either debug or release.
