Problem
=======
Gdb is the canonical debugger for go programs. Package golang-src
provides a python file /usr/share/go/src/pkg/runtime/runtime-gdb.py to
assist go programmers with specialized gdb commands (I don't really know
just how useful they are). gdb complains when it starts that it can't
load /usr/share/go/src/pkg/runtime/runtime-gdb.py because its not on the
"auto-load safe-path":
$ gdb ./hello

warning: File "/usr/share/go/src/pkg/runtime/runtime-gdb.py" auto-loading has
been declined by your `auto-load safe-path' set to
"$debugdir:$datadir/auto-load".
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ warning above
(gdb)
I mitigated this by adding the following gdb directive in /etc/gdb/gdbinit:
add-auto-load-safe-path /usr/share/go/src/pkg/runtime
Then:
$ gdb ./hello

Loading Go Runtime support.
^^^^^^^^^^^^^^^^^^^^^^^^^^ success indicated above
(gdb)
I'm not sure how best to solve this in general, but golang-src probably needs
to configure gdb to accept
/usr/share/go/src/pkg/runtime/runtime-gdb.py as safe.
It took me a little while to figure out how auto-load safe-path works,
how gdb initializes on start, where the files are located such as
/etc/gdb/gdbinit and ~/.gdbinit. So it takes a little investigation for
a programmer to reconstruct what I did above. But its also a fixable
annoyance.
