Some feedback about the python scripting feature

[Marcelo Taube]

Dear gdb team,

I have been using the python scripting feature of gdb7

The feature is great it let me debug my code much better and in a much 
flexible way.

There are some features missing which would improve it even more, though.

I want to mention them in case noone did it before.

    * *calling functions*: From regular gdb command line the user can
      allways simply do " p foo()" to call function and print the
      result, it would be usefull to be able to call C functions (or the
      debugged lenguage) from python and get the result as a Value
      object in the same way a variable is accessed.
    * *equality of types: *i think there are problems with the equality
      of types in gdb. Look at the case that  two type objects were
      obtained and represent the same type, the expression
      'gdb.lookup_type("int") == gdb.lookup_type("int")' now returns
      false but it should return true.
    * *interactive python: *the current python command reads lines using
      gdb normal input instead of the regular python prompt line, making
      some nice features of python unavailable like
      completions-proposals (pressing the tab-key to get the name of a
      function completed) or auto indentation. Maybe running the regular
      python prompt line can be an option.
    * *regular members instead of dictionaries: *it would be more
      natural to have members of structs be accessed in their natural
      way like in c. For example if we have some struct "struct Type {
      int a; int b;}" and we have a value object in python called
      'value', Now to access 'value.a' we have to do 'value["a"]' but
      that feels preety unnatural, why not just support the syntax
      'value.a' ?

Thank you so much for your excelent work and for the time you spent 
reading this lines
