breakpoints

Every time I refresh my web app with the Chrome Inspector open it pauses and takes me to the sources tab with a big red arrow icon pointing to some weird line inside jQuery. I see Paused in debugger in the top-middle of the window, and Paused on exception: DOMException in the Call Stack on the sources tab. As far as I'm aware, I haven't set any breakpoints and this code wasn't throwing exceptions before - so what's going on? That little pause icon in the lower left. Should be black in color. Click it to cycle through several breakpoint options. I had been debugging and forgotten to remove a

I am pretty sure I have seen this before, but I haven't found out / remembered how to do it. I want to have a line of code that when executed from the Delphi debugger I want the debugger to pop-up like there was a break point on that line. Something like: FooBar := Foo(Bar); SimulateBreakPoint; // Cause break point to occur in Delphi IDE if attached WriteLn('Value: ' + FooBar); Hopefully that makes sense. I know I could use an exception, but that would be a lot more overhead then I want. It is for some demonstration code. Thanks in advance! Joeri Sebrechts To trigger the debugger from code

What is the difference between hardware and software breakpoints? Are hardware breakpoints are said to be faster than software breakpoints, if yes then how, and also then why would we need the software breakpoints at all? This article provides a good discussion of pros and cons: http://www.nynaeve.net/?p=80 To answer your question directly software breakpoints are more flexible because hardware breakpoints are limited in some functionality and highly architecture-dependant. One example given in the article is that x86 hardware has a limit of 4 hardware breakpoints. Hardware breakpoints are

I am currently debugging complex JavaScript code with Firebug. I am looking for a way to stop the JavaScript execution as if it was a breakpoint programmatically. Example: instructions ... degugger.breakpoint(); // the execution stops here as if a breakpoint was // manually set other instructions ... RaYell You can use the debugger statement: // your JS code ... // break here debugger; It works in all major browsers. 来源： https://stackoverflow.com/questions/1265623/programmatically-stop-javascript-execution-in-firebug

I'm an experienced developer, but new to iOS/Objective C. The app below builds OK (modulo any typo/cut'n'paste errors). When I run it, it breaks in the print method, in a way that makes it look like there is some error. I cannot see what or where the error is. Probably a real newby error though! Can anyone help me out by explaining what I am doing wrong and how to fix it? This is a command line MacOS app, with Foundation, being built & run in XCode. @interface DayOfYear : NSObject - (void) print; - (id) init : (int) day; @end // DayOfYear @implementation DayOfYear int dayInYr =0; - (id) init :

I wrote a very simple Qt program here: int main(int argc, char* argv[]) { QApplication app(argc, argv); QTableView table(&frame); table.resize(100, 100); table.show(); return app.exec(); } And when I try to set a breakpoint where the table gets clicked, I get this error from gdb: (gdb) symbol-file /usr/lib/libQtGui.so.4.4.3.debug Load new symbol table from "/usr/lib/libQtGui.so.4.4.3.debug"?
