[jira] [Created] (ARROW-12735) [C++][Dev] Write gdb plugin

Antoine Pitrou created ARROW-12735:
--------------------------------------

             Summary: [C++][Dev] Write gdb plugin
                 Key: ARROW-12735
                 URL: https://issues.apache.org/jira/browse/ARROW-12735
             Project: Apache Arrow
          Issue Type: Wish
          Components: C++, Developer Tools
            Reporter: Antoine Pitrou


One common issue when using gdb with Arrow is that it's non-trivial to explore and display Arrow data and metadata using built-in gdb functionality. One usually needs lots of hand typing of expressions.

One way to alleviate this would be to write a gdb plugin giving a higher-level view of Arrow C++ objects. This should be possible using the gdb Python API (though not trivial):
https://sourceware.org/gdb/current/onlinedocs/gdb/Python.html#Python

A sophisticated example of this is the gdb plugin for Python itself:
