Debugging git on MS Windows

[Thiago Farina]

Hi guys,

How can I debug git on Windows? I'm able to compile git through the
make that was installed by msysgit installation.
But I want to debug, not only build. I think is not possible to
compile and debug git with Visual Studio, or is it possible?

If is not possible, what are the other methods to debug git?

Thanks all!

Did you actually just go and try to debug it?

Yeah, I mean, I created a Solution in Visual Studio that I imported
all *.c and *.h files from git.
But it requires many headers that only mingw provide, like unistd.h,
sys/param.h, dirent.h, sys/time.h, fnmatch.h, utime.h. So I can't
compile because of these headers, and I read something that git
depends in many others third_party libraries, like curl, openssl, etc.

I thought that if you guys are building the msysGit, you must are
debugging it somehow that I don't know.

msvc is not supported

yes, with gdb :-)

Thanks for the hint.

For those who are interested in debugging git on windows:
I downloaded the dgb from here:http://sourceforge.net/projects/mingw/
files/GNU%20Source-Level%20Debugger/

After I searched for a tutorial how to use gdb, and I found this
tutorial: http://www.chemie.fu-berlin.de/chemnet/use/info/gdb/gdb_toc.html

And I succeeded to debug git on windows. But I felt so strange to have
to be typing the commands all the time.

The steps I'm doing to debug are:
- c:\mingw\bin\gdb.exe c:\msysgit\bin\git.exe
- <gdb> b git.c:458
- <gdb> run
- continue or step
- print variable_name

I was more accustomed to just press F5 (debug) and then F11 in Visual
Studio.

...or they could just download the msysgit environment, which already
includes gdb.

unfortunately, that's the cost of using mingw.

Maybe the word "complete" is missing from "msysGit is the build
environment for Git for Windows".

There's ddd, I hear. I'm not opposed to bundling it if somebody does the
work of verifying that it works nicely, and of making a proper patch. Not
opposed at all.

Of course, I'm opposed to that idea. :-)

Bundle KDbg!! Oh, wait... KDbg does not exist for Windows :(

Eclipse runs on Windows. It runs fine with the msys/mingw build
environment. Maybe there's a way you could use that one for git as well.
It has a nice gui for debugging. And once you get used to it, it is
close in user experience terms of Visual Studio...

Once you get it running, please tell us how :)

[Thiago Farina]

Ok, I'm trying this options as you suggested. But I have no experience
with this IDE, and I don't like eclipse, but I will try.

Do you know how can I set the include paths?
For example how eclipse will know that the "fnmatch.h" in under
compat/fnmatch directory?
In Visual Studio I know how to do this but, but in eclipse no.

Hi,

I'm not opposed to that, either, if you get it to run and provide me with
a patch I can lazily apply while continuing to nurse my White Russian.

Now that's funny! Love this group.

In eclipse do:
- Rightclick project
- Properties
- C/C++ Build
- Settings
- GCC C++ Compiler
- Directories

Here you can add include directories to your eclipse config.

Sorry, I meant GCC C Compiler in stead of GCC C++ Compiler :)
