Break on variable value change in Android Studio 1.1.0?

不羁的心 提交于 2019-12-31 11:32:39
问题 I know I could set a breakpoint at every line where my code changes the variable, but is there an option such as right-clicking a variable (to "Add to Watches") that would stop when a variable changes value? I think C++ has this option. See this. And Eclipse? See this. Is this implemented in AS? 回答1: You can break on value changes of some variables in Android Studio 1.1.0. Android Studio calls them 'Java Field Watchpoints'. From the breakpoints windows, (Run -> "View breakpoints...") or Ctrl

Debug C++ program in Linux

守給你的承諾、 提交于 2019-12-31 10:33:24
问题 I have written a simple C++ program like this: #include <iostream> using namespace std; int main() { cout << "Hello."; return 0; } Now I want to debug it. So what will be the command for it so my control goes to every line? 回答1: You can use gdb for this: $ gdb hello This will start gdb and prompt you for what to do next. The next command executes one line of source and stops at the next line. I found a basic GDB tutorial that may be helpful. 回答2: Don't forget to compile your source code using

eclipse debugger: attaching source-code of maven dependencies?

会有一股神秘感。 提交于 2019-12-31 10:22:11
问题 I'd like to use the source code of maven-managed dependencies when debugging our webapp in myEclipse 8. I have managed to attach the sources to the libraries in the "Maven Managed Dependencies" classpath container, i.e. when I open a class file from a dependency (e.g. using Ctrl-Shift-T), I see the source code. However, when I define a server connector for my tomcat, deploy the wepapp to it, and launch it in debug mode and execution halts on a breakpoint in that same class, the editor pane

Breakpoints out of nowhere when debugging with gdb, inside ntdll

问题 I made a very simple program which automates some things for me.I wrote it in c++ and it runs on Windows. While debugging it with GDB from inside the Codeblocks IDE , I get many breakpoints out of nowhere. I have no idea what might be causing this problem. The breakpoints seem to be related with memory issues ... since when I fixed a memory leak I had detected, the breakpoints number got significantly less. The exact thing that gdb tells me is: Program received signal SIGTRAP, Trace

Visual patterns in memory?

旧巷老猫 提交于 2019-12-31 08:57:15
问题 Started up remote debugging a C++ project today on a Win 7 machine running in VMWare and was astonished to see the following pattern on a random memory location: Who might code this (it's not me!) and for what reason?? Just curious if anyone has seen something like this. 回答1: It looks like a rendered mask for a font (each character in a font (typeface+size+style) is rendered once in-memory, then blitted to the output surface) using 8bpp, which suggests you've got font anti-aliasing enabled. I

Why are assertEquals() parameters in the order (expected, actual)?

社会主义新天地 提交于 2019-12-31 08:52:18
问题 Why do so many assertEquals() or similar function take the expected value as first parameter and the actual one as second ? This seems counter-intuitive to me, so is there a particular reason for this unusual order ? 回答1: Because the authors had a 50% chance of matching your intuition. Because of the other overload assertWhatever(explanation, expected, actual) And the explanation, which is part of what you know, goes with the expected, which is what you know, as opposed to the actual, which

msvsmon.exe crashed when debugging

问题 When I debugging in VS2013 update3, msvsmon.exe crashed when hit at a breakpoint. It shows "The debugger's worker process (msvsmon.exe) unexpectedly exited. Debugging will be aborted". I'm not using remote debug. Is it possible to shut down the msvsmon.exe to avoid calling it when debugging ? 回答1: Deleting all of the breakpoints solves the problem when I hit this error. Disabling the breakpoints was not enough - they had to be deleted. I was able to attach to a process numerous times. Once I
