PDB files map an assembly’s MSIL to the original source lines. This means that if you put the PDB that was compiled with the assembly in the same directory as the assembly, your exception stack traces will have the names and lines of the positions in the original source files. Without the PDB file, you … Read more
To break on all exceptions, caught or uncaught: Open the Breakpoints window via Run -> View Breakpoints. The Breakpoints dialog appears. In the left pane, scroll to the bottom. Select Any exception under Java Exception Breakpoints With Any exception selected, on the right pane, configure as follows: Suspend: checked All: selected Condition: !(this instanceof java.lang.ClassNotFoundException) … Read more
There’s the more general but perhaps not as helpful to you Wireshark. One of the SO server sites might be better suited for your question. In fact, it’s already been asked on SuperUser.
Everytime docker successfully executes a RUN command from a Dockerfile, a new layer in the image filesystem is committed. Conveniently you can use those layers ids as images to start a new container. Take the following Dockerfile: FROM busybox RUN echo ‘foo’ > /tmp/foo.txt RUN echo ‘bar’ >> /tmp/foo.txt and build it: $ docker build … Read more
Yes! With the new version 7.0 gdb, you can do exactly that! The command would be “reverse-step“, or “reverse-next“. You can get gdb-7.0 from ftp.gnu.org:/pub/gnu/gdb If you run into the error: Target child does not support this command. then try adding target record at the beginning of execution, after starting run. Edit: Since GDB 7.6 … Read more
I imagine there are better ways to do it, but the finish command executes until the current stack frame is popped off and prints the return value — given the program int fun() { return 42; } int main( int argc, char *v[] ) { fun(); return 0; } You can debug it as such … Read more
What I’d like to do is insert a bit of code at the particular point that I want to start debugging. I usually do it like this: volatile int done = 0; while (!done) sleep(1); Attach GDB (you’ll be inside sleep). Do finish, then set var done = 1, and enjoy the rest of your … Read more
Bare minimum -Og/-O0 -O0 basically tells the compiler to make no optimisations. Optimiser can remove some local variables, merge some code blocks, etc. and as an outcome it can make debugging unpredictable. The price for -O0 option is very slow code execution, but starting from version 4.8 GCC compilers (including the Fortran one) accept a … Read more
There’s also dotrace, which allows you to look at the inputs and outputs of selected functions. (use ‘clojure.contrib.trace) (defn fib[n] (if (< n 2) n (+ (fib (- n 1)) (fib (- n 2))))) (dotrace [fib] (fib 3)) produces the output: TRACE t4425: (fib 3) TRACE t4426: | (fib 2) TRACE t4427: | | (fib … Read more
If you look in [File menu ->] Settings -> Debugger -> Stepping you will see a list “Do not step into these classes”, probably with “java.*” listed there. Is that the case? You can turn that off there. Apparently the debug information is not available. According to this thread: Sadly the JDK classes have debug … Read more
