[C++][Dev] Write gdb plugin

    XMLWordPrintableJSON

Details

    Description

      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 simple example:
      https://github.com/nlohmann/json/tree/develop/third_party/gdb_pretty_printer

      A sophisticated example of this is the gdb plugin for Python itself:
      https://github.com/python/cpython/blob/main/Tools/gdb/libpython.py
