            Bug ID: 29217
           Summary: gdb.set_parameter doesn't accept a bool where
                    gdb.parameter returns one
           Product: gdb
           Version: HEAD
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: python
          Assignee: unassigned at sourceware dot org
          Reporter: plasmahh at gmx dot net
  Target Milestone: ---

bool settings return bools in python:

> python print(type(gdb.parameter("may-interrupt")))
<class 'bool'>


but do not accept them:

> python gdb.set_parameter("may-interrupt",False)
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/plasmahh/opt/gdb/share/gdb/python/gdb/__init__.py", line 237,=
 in
set_parameter
    execute("set " + name + " " + str(value), to_string=3DTrue)
gdb.error: "on" or "off" expected.
Error while executing Python code.


which paticularily also breaks gdb.with_parameter() for bool values.


While something like if( isinstance(gdb.parameter(name),bool) ): value =3D {
True:"on",False:"off"}[value]
will fix this particular case, it might make more sense to enhance the gdb =
core
functionality to accept "True" (and maybe "true") too since despite the
message, 1, "yes" and "enable" are already accepted.
